###### Strengths and limitations of this study

</div>

- This review analysed various workplace well-being strategies, both individually and organisationally focused interventions for physicians, nurses and allied healthcare workers.

- The reported evidence in this review builds on previous evidence in the literature that focused on specific well-being interventions such as mindfulness-based practices and contrasts these results against other types of workplace well-being interventions.

- A quantitative meta-analysis was not possible due to the marked variation in study designs and reported outcomes implemented by the eligible studies.

- Organisationally focused interventional studies were under-represented in this review with only three meeting the inclusion criteria.

# Introduction

Widely acknowledged as the cost of caring, healthcare workers report higher rates of absences due to psychological distress and job burnout than workers in other sectors.<span class="citation" data-cites="R1"><sup>1–6</sup></span> Psychosocial hazards such as chronic exposure to occupational stress, place healthcare workers at greater risk of presenteeism (reduced productivity), anxiety and depression.<span class="citation" data-cites="R3"><sup>3 7–9</sup></span> Occupational stress relates to workplace interferences that can disturb a worker’s well-being physically and mentally, thereby fostering the potential for burnout.<span class="citation" data-cites="R1"><sup>1 10</sup></span> Moreover, the financial constraints of healthcare systems within developed countries are further pressurised by an ageing patient population, technological advances and poor worker retention.<span class="citation" data-cites="R10"><sup>10–12</sup></span> The Australian Institute of Health and Safety estimated in 2019, that worker’s absenteeism due to poor mental health, cost between \$13 and \$17 billion per year.<span class="citation" data-cites="R13"><sup>13</sup></span> These figures were exponentially compounded throughout the recent COVID-19 pandemic.<span class="citation" data-cites="R9"><sup>9 10 14</sup></span> For example, in a study conducted in England during the first wave of COVID-19, sickness absences due to poor mental health in National Health Service staff, increased from 519 807 days in March–April of 2019 to 899 730 days 12 months later.<span class="citation" data-cites="R14"><sup>14</sup></span>

The reduced productivity of healthcare professionals in the workplace can lead to suboptimal delivery of care to patients and therefore poorer treatment outcomes.<span class="citation" data-cites="R6"><sup>6 10</sup></span> Consequently, there is growing interest in boosting healthcare worker wellness, resiliency and self-care, globally.<span class="citation" data-cites="R6"><sup>6</sup></span> The framework for occupational health and safety is moving beyond traditional workplace hazards and now seeks to include emerging demographic factors such as mental health conditions.<span class="citation" data-cites="R15"><sup>15</sup></span> This view is reflected in the 2030 United Nations Goal that employment respects the ‘… physical and mental integrity of the worker in the exercise of his or her employment’.<span class="citation" data-cites="R15"><sup>15</sup></span> Additionally, in July 2022, Safe Work Australia released new codes of practice for managing psychosocial hazards at work, including risks to workers’ mental health.<span class="citation" data-cites="R16"><sup>16</sup></span> Using theoretical frameworks such as the Job Demands-Resources (JD-R) model or Watson’s Human Caring theory, researchers are developing support strategies that aim to improve well-being as well as understand worker’s wellness and exhaustion.<span class="citation" data-cites="R7"><sup>7 17</sup></span> Both these validated frameworks are invaluable to well-being researchers as the JD-R model explains how increasing job resources can buffer job strain in workers, while Watson’s theory of Human Caring aims to create a holistic or mind-body-soul approach to human care.<span class="citation" data-cites="R17"><sup>17–19</sup></span> The literature demonstrates that workers who receive treatment for absenteeism and presenteeism, for example, through workplace well-being interventions, report higher levels of productivity, which can then lead to higher levels of job satisfaction.<span class="citation" data-cites="R3"><sup>3</sup></span> Furthermore, workplace interventions that focus on self-care, worker empowerment and access to mental health services such as mindfulness sessions or meditation, have been found to decrease levels of psychological stress, anxiety and burnout in healthcare workers.<span class="citation" data-cites="R20"><sup>20</sup></span>

Workplace interventions may be designed and applied based on the level at which behavioural changes are targeted, for example, the individual worker, manager or the organisation itself.<span class="citation" data-cites="R21"><sup>21</sup></span> Interventions designed to target health behaviours for the individual, such as mindfulness-based practices, gratitude journaling, meditation or yoga are increasingly popular among researchers.<span class="citation" data-cites="R8"><sup>8 22–24</sup></span> As such, several recent systematic reviews have reported the benefit of individual focused interventions in healthcare, predominantly highlighting the effectiveness of mindfulness-based practices to improve well-being.<span class="citation" data-cites="R22"><sup>22–24</sup></span> Organisational interventions designed to target the source of occupational stress such as reducing workloads, increasing autonomy or job crafting (physical and cognitive changes individuals make in the task or relational boundaries of their work<span class="citation" data-cites="R25"><sup>25</sup></span>), are less explored.<span class="citation" data-cites="R21"><sup>21</sup></span> The predominant view in the literature is that interventions designed to alter health behaviours in the individual, may be a reactive strategy to occupational stress, whereas organisational change may be far more proactive in promoting worker well-being in the long term.<span class="citation" data-cites="R21"><sup>21 25</sup></span> A recent surge in the understanding of workplace wellness and causes of occupational stress further promotes the need to explore and invest in organisational strategies.<span class="citation" data-cites="R26"><sup>26 27</sup></span> As it stands, institutions may be reluctant to implement large organisational changes without strong literature evidence supporting the effectiveness and long-term benefits to employees.<span class="citation" data-cites="R26"><sup>26 27</sup></span>

A second approach to implementing workplace well-being interventions can be achieved through first identifying the presence and likely cause of occupational stress and then applying the intervention at either the primary, secondary or tertiary level.<span class="citation" data-cites="R28"><sup>28</sup></span> Primary interventions may be implemented in a largely preventative manner as they aim to eliminate occupational stress or change the cause of stress such as through workload reductions.<span class="citation" data-cites="R28"><sup>28</sup></span> Secondary and tertiary interventions are designed to treat workers who are already showing signs of occupational stress. Secondary interventions aim to help workers minimise the effects of occupational stress through methods such as relaxation training and tertiary interventions aim to treat workers who have already developed stress-related health issues such as anxiety or depression.<span class="citation" data-cites="R28"><sup>28</sup></span>

To date, a multitude of systematic reviews have investigated the effects of mindfulness-based education or yoga interventions for healthcare professionals in a wide array of contexts. For example, Lomas *et al*<span class="citation" data-cites="R22"><sup>22</sup></span> conducted a meta-analysis investigating the impact of mindfulness-based interventions on healthcare workers, Cocchiara *et al*<span class="citation" data-cites="R29"><sup>29</sup></span> investigated the use of yoga to manage stress and burnout in healthcare workers and Klein *et al*<span class="citation" data-cites="R30"><sup>30</sup></span> investigated the benefits of mindfulness-based interventions on burnout among health professionals. Other systematic reviews have focused on specific populations, for example, DeChant *et al*<span class="citation" data-cites="R31"><sup>31</sup></span> investigated the effect of organisation-directed workplace interventions on physician burnout and Murray *et al*<span class="citation" data-cites="R32"><sup>32</sup></span> investigated interventions to improve the psychological well-being of general practitioners. To the authors knowledge, no systematic review has been conducted to provide an overview of all types of well-being interventions for allied healthcare professionals, including physicians and nurses. The authors also acknowledge the effects that COVID-19 has had on healthcare practices as well as healthcare worker mental well-being.<span class="citation" data-cites="R14"><sup>14</sup></span> Therefore, in order to include all above-stated professional groups and types of interventions in this review, as well as sampling the most recent research (including 5 years prior to the onset of COVID-19), the search criterium for this review was restricted to 2015.

This systematic review therefore aims to identify and analyse all positive outcome measures produced by workplace interventional strategies designed to support well-being and reduce burnout for nurses, physicians and allied health professionals since 2015.

# Methodology

A search strategy was developed by the research team and validated by an institutional research librarian using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines prior to searching the literature and we used the PRISMA checklist when writing our report.<span class="citation" data-cites="R33"><sup>33 34</sup></span> The full search protocol, including the search terms, can be found in <a href="#SP1" data-ref-type="supplementary-material">online supplemental appendix</a>. Title and abstract screening as well as full-text screening was carried out by two members of the research team (CC, JC). Where there were disagreements or uncertainty, a third, senior member of the research team was available for resolution if reconciliation sessions were unsuccessful.

## Patient and public involvement

There was no patient or public involvement in this research.

## Eligibility criteria

### Population

All studies in which the sampled population included either allied health personnel, physicians or nurses were included in this review. Studies that contained mixed populations that is, healthcare workers as well as patients, were included, however, data not pertaining to healthcare workers were excluded. Studies that did not confirm that healthcare workers, physicians or nurses were involved in the intervention, were also excluded. A summary of the allied health professions included in this review, both regulated by the Australian Health Practitioner Regulation Agency and self-regulated, as per the Australian Government Department of Health can be found in <a href="#SP1" data-ref-type="supplementary-material">online supplemental file 1</a>.<span class="citation" data-cites="R35"><sup>35</sup></span>

### Interventions

This review accepted all studies reporting the outcomes of either organisationally or individually focused workplace well-being interventions. Studies whereby improving employee well-being or reducing burnout was not the primary focus of the intervention, were excluded. Studies that suggested workplace interventions but did not implement them were also excluded.

### Outcome measures

All study designs were accepted if objective and quantifiable preintervention and postintervention outcome measures such as observer ratings were reported, using a valid and reliable well-being or burnout survey inventory. Systematic literature reviews were not included in the initial synthesis; however, they were included in the discussion and summary of study findings. Studies published prior to 2015 were also excluded to ensure the most up to date literature was reviewed (while still including 5 years prior to the onset of COVID-19) as well as including all well-being intervention types for nurses, physicians and allied healthcare professionals.

### Literature search

Five healthcare/medicine databases (CINAHL, Embase, Emcare, Medline, PsycInfo) were searched on 2 May 2022 and again on 5 October 2022 using a three-step (Population, Intervention, Outcome) systematic approach (see inclusion criteria for details). A secondary search of Google Scholar was also performed with results limited to the first five pages of articles (n=50). The outcomes of the literature search are outlined in <a href="#F1" data-ref-type="fig">figure 1</a>.

</figure>

### Study selection

Data extraction was performed by the first author (CC) and verified by all other members of the research team (EB, JC, SP and MT). The extracted data was summarised into an Excel spreadsheet and comprised study design, objectives, location, participants (numbers and characteristics), sample size justification, number of institutions, outcome measurement tools, intervention used (type, repeatability, random or blinded), data collection timeframe, ethical approval, rate of attrition, quantitative data results and study outcomes.

### Quality assessment

Quality assessment of the articles was also carried out independently by two members of the research team (CC and JC) using the Medical Education Research Study Quality Instrument (MERSQI).<span class="citation" data-cites="R36"><sup>36</sup></span> The MERSQI is a long-standing and validated quality assessment tool that is applicable to a wide array of study designs.<span class="citation" data-cites="R35"><sup>35</sup></span> Papers were given scores (out of a maximum of 18) based on study design, number of institutions, response, type, validity of the methods, sophistication of data analysis, appropriateness and reported outcomes.<span class="citation" data-cites="R36"><sup>36</sup></span>

### Meta-analysis

It was not possible to perform a meta-analysis due to a marked variation in study designs, interventions employed, survey instruments used and statistical analyses performed.

# Results

The database searches produced 1596 total articles for screening. A grey literature search of Google Scholar as well as Pearling reference lists generated a further 67 papers. In total, 545 articles were marked as duplicates. Of the remaining 1118 articles, 921 were removed during title and abstract screening. Of the 197 full-texts articles, 40 were included in this review. Following quality assessment, seven papers that scored 12 points or lower were excluded from data synthesis leaving 33 articles for analysis.

## Characteristics and quality of studies

The full results of the quality assessment are available in <a href="#SP2" data-ref-type="supplementary-material">online supplementary table 1</a>. All articles in this review were published between 2015 and 2022 with most studies (n=22) based in the USA.<span class="citation" data-cites="R1">1 4 7 17 26 37–53</span> Two studies were based in Australia,<span class="citation" data-cites="R54"><sup>54 55</sup></span> two in the Netherlands<span class="citation" data-cites="R56"><sup>56 57</sup></span> and one each from Ireland,<span class="citation" data-cites="R58"><sup>58</sup></span> Italy,<span class="citation" data-cites="R59"><sup>59</sup></span> Portugal,<span class="citation" data-cites="R60"><sup>60</sup></span> Brazil,<span class="citation" data-cites="R61"><sup>61</sup></span> Hong Kong,<span class="citation" data-cites="R12"><sup>12</sup></span> Japan<span class="citation" data-cites="R62"><sup>62</sup></span> and Iran.<span class="citation" data-cites="R63"><sup>63</sup></span> Twenty-seven<span class="citation" data-cites="R1">1 4 7 12 26 37–52 54 58–61 63</span> studies had participants that were predominantly female, two<span class="citation" data-cites="R56"><sup>56 57</sup></span> reported more male than female participants and four<span class="citation" data-cites="R17">17 46 53 55</span> did not specify gender. A total of 16<span class="citation" data-cites="R17">17 37 39 42 44 46–48 50–54 60 61 63</span> articles reported that nurses were the sole participants in their studies, 5<span class="citation" data-cites="R26">26 38 43 56 57</span> reported physicians only, 1<span class="citation" data-cites="R59"><sup>59</sup></span> reported sampling both physicians and nurses, 5<span class="citation" data-cites="R1">1 12 40 49 55</span> sampled a variety of healthcare workers (including allied health) and 6<span class="citation" data-cites="R4">4 7 41 45 58 62</span> articles used generic terminology such as healthcare professionals, hospital staff or clinical/non-clinical roles.

In the five studies that sampled various allied healthcare professionals, three<span class="citation" data-cites="R1"><sup>1 40 55</sup></span> studies listed social workers, three<span class="citation" data-cites="R12"><sup>12 49 55</sup></span> included occupational therapists, two<span class="citation" data-cites="R1"><sup>1 55</sup></span> mentioned psychologists/therapists, two<span class="citation" data-cites="R12"><sup>12 49</sup></span> reported physiotherapists, two<span class="citation" data-cites="R40"><sup>40 49</sup></span> included pharmacists and one<span class="citation" data-cites="R49"><sup>49</sup></span> study mentioned technologists/technicians. Sample sizes ranged from 9<span class="citation" data-cites="R55"><sup>55</sup></span> to 228<span class="citation" data-cites="R49"><sup>49</sup></span> with 11<span class="citation" data-cites="R7">7 12 39 43 44 48 49 52 57 60 62</span> studies providing a power analysis to sample size justification.

Eight<span class="citation" data-cites="R4">4 12 37 41 43 63</span> studies used randomised controlled trials (RCTs), six<span class="citation" data-cites="R26">26 40 43 44 57 60</span> used quasi-experimental study designs and nineteen<span class="citation" data-cites="R1">1 7 17 42 45–55 58 59 61 62</span> used a single group pretest/post-test study design method. Of the 14 studies that implemented a control group, 3<span class="citation" data-cites="R4"><sup>4 12 44</sup></span> used an active control method, 4<span class="citation" data-cites="R26">26 39 43 63</span> chose no treatment control groups and 7<span class="citation" data-cites="R37">37 38 40 41 56 57 60</span> implemented waitlist control groups. Seventeen<span class="citation" data-cites="R4">4 37 38 40 42 44 45 47 50 51 53–55 57 59 60 63</span> studies implemented interventions incorporating mindfulness based education (MBE) such as stress management, resiliency training, emotional intelligence training, or improving mindfulness and self-compassion. Three<span class="citation" data-cites="R7"><sup>7 17 41</sup></span> studies opted for MBE combined with yoga and one<span class="citation" data-cites="R39"><sup>39</sup></span> study used yoga only. The remaining studies implemented a myriad of well-being interventions including gratitude journaling,<span class="citation" data-cites="R12"><sup>12 49 62</sup></span> meditation sessions,<span class="citation" data-cites="R48"><sup>48 61</sup></span> workload reduction,<span class="citation" data-cites="R26"><sup>26 56</sup></span> massage chairs,<span class="citation" data-cites="R46"><sup>46</sup></span> choir singing,<span class="citation" data-cites="R58"><sup>58</sup></span> acupuncture,<span class="citation" data-cites="R1"><sup>1</sup></span> professional coaching<span class="citation" data-cites="R43"><sup>43</sup></span> and a peer support network (PSN).<span class="citation" data-cites="R52"><sup>52</sup></span>

The longest intervention period was 6 months,<span class="citation" data-cites="R44"><sup>44</sup></span> and the shortest intervention period was 90 min.<span class="citation" data-cites="R50"><sup>50</sup></span> In each study, participants were issued surveys at baseline and immediately following the intervention. Several studies also issued additional follow-up surveys at either 1, 3, 6 or 12 months postintervention. Overall, attrition rates were low across the studies with 19<span class="citation" data-cites="R12">12 17 39–44 46 47 49–51 55 58 59 61–63</span> reporting they experienced 0% participant dropout and only 5<span class="citation" data-cites="R1">1 45 52 53 60</span> recording 25% or greater attrition. For some studies, it was difficult to quantify attrition rates, for example, Bevan and Emerson<span class="citation" data-cites="R42"><sup>42</sup></span> reported 0% attrition yet also stated that two out of three mindfulness sessions were not attended by all participants (session one 53% and session two 85% attendance). In another web-based study,<span class="citation" data-cites="R37"><sup>37</sup></span> 10 out of 52 experimental participants did not withdraw from the study but never actually logged online to use the programme. All studies provided sufficient details regarding the interventions used, to ensure repeatability. All outcome measures relating to well-being or burnout were evaluated for this review, however burnout, perceived stress, depression, and anxiety as well as resilience, quality of life and work engagement levels were of particular interest to the authors. A full summary of the wellbeing interventions analysed in this review are outlined below in <a href="#T1" data-ref-type="table">table 1</a>.

## Organisationally focused interventions

Three<span class="citation" data-cites="R26"><sup>26 52 56</sup></span> of the thirty-three studies implemented workplace interventions focused on the organisation altering daily practices and protocols to enhance worker well-being. Two<span class="citation" data-cites="R26"><sup>26 56</sup></span> of these studies used interventions designed to eradicate or eliminate stress in the workplace and were therefore categorised as primary level interventions and one<span class="citation" data-cites="R52"><sup>52</sup></span> was secondary that is, participants were managed for symptoms of occupational stress. Gordon *et al*<span class="citation" data-cites="R56"><sup>56</sup></span> implemented general job crafting strategies based around weekly goals to promote teamwork and increase quality of care for medical specialists and nurses, through training and setting personal goals. In the study conducted by Gregory *et al*<span class="citation" data-cites="R26"><sup>26</sup></span> workloads for physicians were reduced, by employing a certified medical assistant to run appointments, manage pharmaceutical refill requests, triage and coordinate care activities.

Finally, a three-tiered PSN programme was delivered by Wahl *et al*<span class="citation" data-cites="R52"><sup>52</sup></span> which consisted of departmental peer supporters, a trained peer support team and mental health experts.<span class="citation" data-cites="R52"><sup>52</sup></span> The key goals of this study were to develop a PSN, identify at-risk colleagues, and understand and deliver therapeutic communications by developing keywords and phrases.<span class="citation" data-cites="R52"><sup>52</sup></span>

The duration of these interventions varied from 3 weeks<span class="citation" data-cites="R56"><sup>56</sup></span> to 3 months<span class="citation" data-cites="R52"><sup>52</sup></span> with only one<span class="citation" data-cites="R26"><sup>26</sup></span> conducting an additional follow-up, 3 months after the intervention. All three studies showed positive results; however, comparison and contrast of efficacy is difficult due to the significant heterogeneity of data collection methods and outcomes measured (see for a summary of all study outcomes). Both Gregory *et al*<span class="citation" data-cites="R26"><sup>26</sup></span> and Gordon *et al*<span class="citation" data-cites="R56"><sup>56</sup></span> implemented quasi-experimental study designs with non-randomised, no treatment and waitlist control groups. Wahl *et al*<span class="citation" data-cites="R52"><sup>52</sup></span> implemented a single group pretest/post-test study design method and recorded a significantly smaller sample size of just 20 participants compared with the other two organisational studies (107<span class="citation" data-cites="R56"><sup>56</sup></span> and 69,<span class="citation" data-cites="R26"><sup>26</sup></span> respectively). All three studies reported on multiple well-being outcomes by using more than one validated survey instrument, however, there was not a wellness inventory (survey tool) that was implemented in all three studies. Gregory *et al*<span class="citation" data-cites="R26"><sup>26</sup></span> and Gordon *et al*<span class="citation" data-cites="R56"><sup>56</sup></span> measured levels of emotional exhaustion (EE) for their participants using the Maslach Burnout Inventory (MBI) and the Oldenburg Burnout Inventory (OLBI).

Both studies demonstrated statistically significant reductions in EE for participants following the intervention in comparison to the control groups, the reduction in EE was also sustained at the 6-month follow-up in the study by Gregory *et al*.<span class="citation" data-cites="R26"><sup>26</sup></span> In the study by Wahl *et al*<span class="citation" data-cites="R52"><sup>52</sup></span> a reduction in the burnout subscale of the Professional Quality of Life Scale (ProQOL-5) was reported by participants following the PSN intervention but it was not significant.<span class="citation" data-cites="R52"><sup>52</sup></span> A significant improvement in mean scores was reported for the Compassion Satisfaction (CS) subscale of the Compassion Practice Instrument (CPI), however, it was noted that comparison of the CS subscales for the ProQOL-5 and the CPI revealed contradictory results in that CS scores decreased following the intervention as measured by the ProQOL-5. It is thought that the CPI may be more sensitive for measuring CS and therefore able to discern more subtle differences.<span class="citation" data-cites="R52"><sup>52</sup></span>

## Individually focused interventions

Thirty<span class="citation" data-cites="R1">1 4 7 12 17 37–51 53–55 57–63</span> studies in this review implemented secondary level well-being interventions that targeted individual behavioural changes by aiming to minimise the effects of stress in participants through such techniques as relaxation training or promoting a positive mindset.

### Relaxation techniques

Various relaxation techniques accounted for 25 of the individually focused intervention studies. MBE was the most consistently implemented (n=20),<span class="citation" data-cites="R4">4 7 17 37 38 40–42 44 45 47 50 51 53–55 57 59 60 63</span> followed by meditation,<span class="citation" data-cites="R45"><sup>45 48</sup></span> yoga,<span class="citation" data-cites="R39"><sup>39</sup></span> acupuncture<span class="citation" data-cites="R1"><sup>1</sup></span> and massage chairs.<span class="citation" data-cites="R46"><sup>46</sup></span>

Of the 20 intervention studies involving MBE, 10<span class="citation" data-cites="R4">4 7 38 40–42 44 50 54 63</span> held in-person educational sessions, 7<span class="citation" data-cites="R17">17 50 51 53 55 59 60</span> applied a combination of in-person education sessions followed by individual practices at home and 4<span class="citation" data-cites="R4">4 37 45 47</span> used online delivery methods either via a smartphone application or web-based programmes. In the study performed by Mistretta *et al*,<span class="citation" data-cites="R4"><sup>4</sup></span> two intervention groups were structured to implement MBE both in-person and via a smartphone application and therefore has been listed two times. Study durations for MBE ranged from 2 to 16 weeks, with a single outlier study running for 6 months (McNulty *et al*<span class="citation" data-cites="R44"><sup>44</sup></span> implemented four MBE sessions throughout a 6-month nursing residency programme). The number of sessions delivered in each MBE programme also varied greatly from a single seminar<span class="citation" data-cites="R50"><sup>50</sup></span> to a 12-session education programme.<span class="citation" data-cites="R62"><sup>62</sup></span> Most delivered between 4 and 12 sessions. Nine out of the twenty studies implementing MBE interventions used control groups and of these, six<span class="citation" data-cites="R37">37 38 40 41 50 60</span> implemented a waitlist style control, two<span class="citation" data-cites="R4"><sup>4 44</sup></span> were active and one<span class="citation" data-cites="R37"><sup>37</sup></span> group received no treatment. The largest sample size was reported by McNulty *et al*<span class="citation" data-cites="R44"><sup>44</sup></span> with 131 participants in the intervention group and 69 in the active control group. The smallest sample was 13.<span class="citation" data-cites="R42"><sup>42</sup></span> All programmes that delivered in-person group-based MBE education reported at least one statistically significant, positive outcome. Four<span class="citation" data-cites="R4">4 7 38 50</span> studies documented EE levels as measured by the MBI with three<span class="citation" data-cites="R4"><sup>4 38 50</sup></span> reporting improvements following the intervention. Although not statistically significant, EE levels did improve in participants in the study by Ofei-Dodoo *et al*<span class="citation" data-cites="R7"><sup>7</sup></span> who also noted that baseline MBI scores were low. This study did show significant reductions in depression, anxiety and stress scores as measured by the Depression Anxiety and Stress Scale (DASS-21) following the intervention, as well as significant improvements in levels of Personal Accomplishment. Changes in stress (DASS-21), as well as levels of perceived stress (Perceived Stress Scale (PSS)) were reported in 7<span class="citation" data-cites="R4">4 7 38 41 44 45 54</span> of the 11 studies. Of these seven, six were statistically significant with Schroeder *et al*.<span class="citation" data-cites="R38"><sup>38</sup></span> Werneburg *et al*<span class="citation" data-cites="R45"><sup>45</sup></span> and Mistretta *et al*<span class="citation" data-cites="R4"><sup>4</sup></span> all reporting that reductions in levels of stress were maintained at the 3-month follow-up. Mistretta *et al*<span class="citation" data-cites="R4"><sup>4</sup></span> also reported improvements in well-being as measured by the WHO Well-being Index (WHO-5) for the in-person intervention group. Schroeder *et al*<span class="citation" data-cites="R38"><sup>38</sup></span> and Colgan *et al*<span class="citation" data-cites="R40"><sup>40</sup></span> both reported improvements in resiliency levels using the Brief Resilience Scale for participants following the MBE sessions compared with the control groups. A substantial increase in resiliency levels was reported by Colgan *et al*<span class="citation" data-cites="R40"><sup>40</sup></span> following the intervention, however, the increase in resiliency for participants in the study by Schroeder *et al*<span class="citation" data-cites="R38"><sup>38</sup></span> was not enough to be significant. Werneburg *et al*<span class="citation" data-cites="R45"><sup>45</sup></span> and Ofei-Dodoo *et al*<span class="citation" data-cites="R7"><sup>7</sup></span> also both reported changes in resilience levels using the Connor Davidson Resilience Scale (CD-RISC) and the Resilience Scale (RS-14), respectively. Neither study employed a control group however both reported substantial improvements in resiliency following the interventions which were maintained at the 3-month follow-up in Werneburg *et al*’s study.<span class="citation" data-cites="R45"><sup>45</sup></span>

Of the seven studies that implemented a combination of in-person MBE followed by self-directed practice, six<span class="citation" data-cites="R17">17 51 53 57 59 60</span> reported on levels of burnout using either the MBI or the ProQOL-5 and of these, two<span class="citation" data-cites="R50"><sup>50 60</sup></span> employed a waitlist control group. Statistically significant reductions in burnout were reported postintervention in the studies by Duarte and Pinto-Gouveia<span class="citation" data-cites="R60"><sup>60</sup></span> and Hevezi.<span class="citation" data-cites="R51"><sup>51</sup></span> There were significant reductions in EE as well as Depersonalisation (DP) levels but not overall burnout in the study by Caponnetto *et al*<span class="citation" data-cites="R59"><sup>59</sup></span> with Verweij *et al*<span class="citation" data-cites="R57"><sup>57</sup></span> documenting significantly reduced DP levels only. Van Horne *et al*<span class="citation" data-cites="R53"><sup>53</sup></span> reported a reduction in burnout for participants who attended three or more OASIS sessions versus those who reported not attending any sessions, however, this study did not report all mean scores. Dobie *et al*<span class="citation" data-cites="R55"><sup>55</sup></span> and Duarte and Pinto-Gouveia<span class="citation" data-cites="R60"><sup>60</sup></span> documented significantly reduced stress levels in participants following the intervention as measured by the DASS-21 and Caponnetto *et al*<span class="citation" data-cites="R59"><sup>59</sup></span> also reported a significant reduction in perceived stress as measured by the PSS. It is worth noting however, that the study by Dobie *et al*<span class="citation" data-cites="R55"><sup>55</sup></span> had strong limitations in that they recruited the smallest sample size of just nine participants. Bianchini and Copeland<span class="citation" data-cites="R17"><sup>17</sup></span> employed the largest sample size (143 participants) yet did not report any statistically significant change in outcome measures following the 12-week didactic intervention. Of the four studies that implemented MBI practices in an online or solely self-directed manner, two<span class="citation" data-cites="R37"><sup>37 47</sup></span> used the web-based BREATHE programme designed to help nurses manage stress. Both studies reported statistically significant changes in levels of stress as measured by the Nurse Stress Scale (NSS) despite the varied study designs.<span class="citation" data-cites="R37"><sup>37 47</sup></span> Hersch *et al*<span class="citation" data-cites="R37"><sup>37</sup></span> implemented an RCT design with a total of 104 participants while Dutton and Kozachik<span class="citation" data-cites="R47"><sup>47</sup></span> used a single group pretest/posttest study design with 31 participants. Participants in both studies were encouraged to login and use the online programme as much as possible within a 2-month<span class="citation" data-cites="R47"><sup>47</sup></span> and 3-month<span class="citation" data-cites="R37"><sup>37</sup></span> period.

The smartphone intervention group in the study by Mistretta *et al*<span class="citation" data-cites="R4"><sup>4</sup></span> reported less significant changes in outcome measures compared with the in-person MBE intervention group. Significant improvements in well-being were reported as measured by the WHO-5, however, this was not maintained at the 6-month follow-up.<span class="citation" data-cites="R4"><sup>4</sup></span> Reductions in stress, anxiety and depression were not enough to be significant for the smartphone group. Two<span class="citation" data-cites="R48"><sup>48 61</sup></span> of the thirty individually focused studies implemented a meditation intervention and one<span class="citation" data-cites="R39"><sup>39</sup></span> implemented yoga. Three<span class="citation" data-cites="R7"><sup>7 17 62</sup></span> of the twenty MBE studies also incorporated yoga as part of the overall mindfulness education programme with one study by Duchemin *et al*<span class="citation" data-cites="R41"><sup>41</sup></span> using a combination of MBE, yoga and meditation. Neither of the meditation studies used a control group and both had relatively small sample sizes (13 and 27 participants). Burnout levels were reported to be significantly reduced in both studies using the MBI<span class="citation" data-cites="R58"><sup>58</sup></span> and the ProQOL-5 burnout subscale.<span class="citation" data-cites="R48"><sup>48</sup></span> dos Santos *et al*<span class="citation" data-cites="R61"><sup>61</sup></span> additionally reported significant reductions in perceived stress as well as trait anxiety using the State-Trait Anxiety Inventory (STAI) which were all further maintained at the 6-week follow-up. Bonamer and Aquino-Russell<span class="citation" data-cites="R48"><sup>48</sup></span> reported that resiliency scores (CD-RISC) significantly increased following the meditation intervention and demonstrated a correlation between resiliency combined with burnout and CS (ProQOL-5).

In the single yoga study by Alexander *et al*<span class="citation" data-cites="R39"><sup>39</sup></span> the intervention group reported significant improvements in self-care as measured by the Health Promoting Lifestyle Profile (HPLP II) and mindfulness as measured by the Freiburg Mindfulness Inventory (FMI) as well as significant reductions in EE and DP postintervention. Yoga was also incorporated into three of the MBE studies with Ofei-Dodoo *et al*<span class="citation" data-cites="R7"><sup>7</sup></span> implementing group mindfulness-based yoga sessions 1 hour a week for 8 weeks. The 43 participants in this study reported significant improvements in depression, anxiety and stress (DASS-21) as well as increased resilience (RS-14) and compassion as measured by the Santa Clara Brief Compassion Scale (SCBCS).<span class="citation" data-cites="R7"><sup>7</sup></span> The other two<span class="citation" data-cites="R17"><sup>17 41</sup></span> MBE studies that incorporated yoga both implemented a control group, and both reported no significant change in burnout (MBI) or perceived stress. Statistically significant reductions in both state anxiety and trait anxiety (STAI) were reported following the auricular (around the ear) acupuncture intervention, and total work engagement scores as measured by the Utrecht Work Engagement Scale (UWES) also showed significant improvement for the 112 participants.<span class="citation" data-cites="R1"><sup>1</sup></span> The study using a massage chair intervention reported substantial reductions in all outcome measures (perceived stress, heart rate, systolic and diastolic blood pressure) for the 51 study participants.

### Promoting a positive mindset

Five of the thirty individually focused studies implemented interventions designed to promote a positive mindset in participants including gratitude journaling,<span class="citation" data-cites="R12"><sup>12 49 62</sup></span> choir singing<span class="citation" data-cites="R58"><sup>58</sup></span> and professional coaching.<span class="citation" data-cites="R43"><sup>43</sup></span> Gratitude journaling interventions are designed to shift thoughts away from the negativity of stress and towards a more positive primary appraisal of a situation.<span class="citation" data-cites="R12"><sup>12</sup></span> Similarly, choral singing research has shown that participants who regularly engage, may experience cognitive benefits through the addition of social routine and meaningful activity to everyday life.<span class="citation" data-cites="R58"><sup>58</sup></span> The professional coaching intervention was also specifically implemented for participants to design and achieve goals, thereby strengthening personal resilience and mindset positivity.<span class="citation" data-cites="R43"><sup>43</sup></span> All three studies that implemented a gratitude intervention had large recruitment numbers with the smallest sample size being 102.<span class="citation" data-cites="R12"><sup>12</sup></span> Cheng *et al*<span class="citation" data-cites="R12"><sup>12</sup></span> implemented a three-arm randomised control trial and overall scored the highest on the MERSQI for quality and design. In addition to a gratitude and control group, Cheng *et al*<span class="citation" data-cites="R12"><sup>12</sup></span> employed a ‘hassle group’ to record only negative work-related events throughout the 4-week intervention. Postintervention, no significant interaction effects with time or other changes were found for the hassle group, suggesting it was indistinguishable from the control group.<span class="citation" data-cites="R12"><sup>12</sup></span> The gratitude group reported significantly less perceived stress, following the intervention, which was also documented at the 3-month follow-up. A reduction in depressive symptoms was also seen over time for the gratitude group compared with the control group. Participants in the study by Komase *et al*<span class="citation" data-cites="R62"><sup>62</sup></span> attended a single 50 min gratitude workshop and were then asked to send lists of three work-related things they were grateful for, three times a week for three consecutive weeks. Gratitude, self-efficacy, psychological distress and job performance improved significantly postintervention. The gratitude study by Sexton and Adair<span class="citation" data-cites="R49"><sup>49</sup></span> also reported significant improvements in both depressive symptoms (Center for Epidemiologic Studies Depression Scale (CES-D)) and subjective happiness (Subjective Happiness Scale (SHS)) following participants keeping a log of everything that went well for 15 days. However, it was also noted in this study, the extent to which participants expressed their gratitude was not known as participants could opt to share their diaries or not.

The study by Moss and O’Donoghue<span class="citation" data-cites="R58"><sup>58</sup></span> reported no significant improvement for any quantifiable outcome measure in this study, however, qualitative findings reported that a workplace choir can promote social connectedness, enjoyment at work and staff engagement.<span class="citation" data-cites="R58"><sup>58</sup></span> Dyrbye *et al*<span class="citation" data-cites="R43"><sup>43</sup></span> implemented professional coaching for 44 participants and assigned the same number of participants to a control group (no treatment). The proportion of participants in the intervention group with high EE, at 5-month follow-up decreased by 19.5% and increased by 9% in the control group. The intervention group also had a significant overall improvement in quality of life as measured by the Quality of Life Scale as well as resilience (CD-RISC) compared with the control group.

### Individual job crafting

Finally, the second intervention group within the study by Gordon *et al*<span class="citation" data-cites="R56"><sup>56</sup></span> implemented individual job crafting to improve work engagement and lower burnout. Participants in the individual job crafting group reported improved work engagement (UWES) as well as significantly lowered levels of EE (OLBI) compared with the waitlist control group.<span class="citation" data-cites="R56"><sup>56</sup></span> Results were comparable to the first group who received a generalised job crafting intervention and therefore no variation in positive study outcomes was reported between the two job crafting treatment groups.<span class="citation" data-cites="R56"><sup>56</sup></span> A detailed breakdown of all study outcomes is outlined below in <a href="#T2" data-ref-type="table">table 2</a>.

Based on reported effect size, this yoga intervention was promising with future research needed. |
| Bevan & Emerson<span class="citation" data-cites="R42"><sup>42</sup></span> 2020 | Mindfulness-based practices | (MDS-R), (PES), (CWEQ-II). | – | MDS Total 132–111, MDS Frequency 38–34, MDS Intensity 65–72, PES Meaning 14–16. | Nurses scored significantly lower means in overall moral distress and frequency after the intervention. However, intensity scores were significantly higher following the intervention. There were no change in scores for perceived personal or group empowerment. There was an improvement seen in the ‘meaning’ subscale of the PES, a measure of a person’s own evaluation pertaining to the importance of their work. |
| Bianchini & Copeland<span class="citation" data-cites="R17"><sup>17</sup></span> 2021 | Yoga and Mindfulness-based practices | (MBI), (PSS). | – | – | Post 12 week intervention, nurses reported a 11% reduction in perceived stress and reduced burnout levels. PSS scores following the intervention were still 3.1% higher than population norms. Burnout was higher in personal accomplishment than emotional exhaustion or depersonalisation. Although there were some improvement in MBI scores, they were not statistically significant. |

# Discussion

Overall, the studies included in this review scored moderate-highly on the MERSQI rating system yet were markedly heterogeneous pertaining to intervention types, study designs, outcome measures and sample sizes implemented. The literature suggests that organisationally focused well-being interventions may be more effective in promoting and maintaining worker well-being however, with only three studies falling under the organisational umbrella, this review cannot confirm or refute this notion. Each organisational intervention reported at least one statistically significant positive outcome, however only the study by Gregory *et al*<span class="citation" data-cites="R26"><sup>26</sup></span> conducted a follow-up beyond the finalisation of the intervention whereby one outcome (workload) had nearly reverted to the baseline measurement (2.5-2.99-2.62).

Both Gordon *et al*<span class="citation" data-cites="R56"><sup>56</sup></span> and Gregory *et al*<span class="citation" data-cites="R26"><sup>26</sup></span> also implemented waitlist style control groups and the final organisational peer support study (Wahl *et al*<span class="citation" data-cites="R52"><sup>52</sup></span>) did not implement a control group at all. The literature reports growing concerns over the use of waitlist style control groups in psychotherapy research, as the outcomes of the interventions may be over-estimated with this type of control.<span class="citation" data-cites="R64"><sup>64</sup></span>

Organisational intervention studies that target work conditions and create a preventative or primary approach to reducing occupational stress are more effective in promoting healthier workplaces yet are far more difficult to feasibly implement.<span class="citation" data-cites="R21"><sup>21</sup></span> Perhaps this explains why all but three of the intervention studies in this review used secondary, individually focused interventions designed to manage the effects of stress in individual workers. These interventions may be implemented for employers who are concerned about staff productivity and retention or to mitigate employee health costs, however, do not address any underlying contributors to occupational stress such as work conditions or environments.<span class="citation" data-cites="R21"><sup>21</sup></span> Three out of 26 studies implementing relaxation techniques, did not report a positively significant outcome nor did one study that promoted a positive mindset. Overall, MBE interventions were successful with all but two reporting significantly positive outcomes, however, out of 20 MBE studies, only 6 conducted follow-ups beyond the intervention period and only two implemented active style control groups.

Many of the studies in this review that implemented MBE interventions reported reductions in participant levels of burnout, perceived stress and anxiety as well as increased resiliency. However, there were limited validation factors implemented to suggest these improvements were the true result of the intervention itself (ie, comparison against an appropriate control group and follow-up conducted beyond the intervention period). Multiple systematic reviews conducted by Lomas *et al*<span class="citation" data-cites="R22"><sup>22 23</sup></span> achieved similar results with overall study findings reporting that mindfulness was generally associated with positive outcomes in relation to most measures, however, the quality of assessed studies was inconsistent, especially noting the lack of RCT study designs that were eligible for inclusion. Kriakous *et al*<span class="citation" data-cites="R24"><sup>24</sup></span> also found that mindfulness based stress reduction techniques were effective in reducing healthcare professionals’ experiences of anxiety, depression and stress but were less effective at reducing burnout or improving resiliency. MBE interventions can be implemented quite sustainably as they are generally performed in the workplace (during scheduled breaks) or through self-directed practices.<span class="citation" data-cites="R22"><sup>22–24</sup></span> Interventions that do not greatly disrupt daily productivity are more easily implemented for longer time periods and make longer term follow-up assessments more achievable.<span class="citation" data-cites="R30"><sup>30–32</sup></span> Despite this, most studies (n=20) in this review did not collect postintervention follow-up data and only one<span class="citation" data-cites="R57"><sup>57</sup></span> study conducted a long-term follow-up (12 months post the gratitude intervention), in which reported improvements were sustained. It is therefore difficult to suggest which interventions show long-term benefits and therefore may be more effective. With the acknowledgement that healthcare workers face especially difficult psychosocial hazards in the workplace, this review suggests that healthcare employees are likely to benefit from a stronger focus on well-being promotion in the workplace. However, with such a large volume of studies attempting to relieve symptoms of burnout by encouraging new health behaviours in employees themselves, rather than affecting change at an institutional level, further interventional research is demanded. Particularly in the form of RCTs with adequate long-term follow-up data collection.

# Conclusion

The results of this review suggest that healthcare workers benefited from workplace well-being interventions, with a wide array of positive outcomes (improvements in well-being, work engagement, quality of life and mindfulness as well as reductions in burnout, perceived stress, anxiety and depressive symptoms) reported. Relaxation techniques targeted at the secondary interventional level (designed to manage stress in the individual worker) were the predominant well-being strategy of choice. The literature suggests this is due to the feasibility of implementing such a study. Reported positive outcomes included: improvement in EE, resilience, mindfulness, well-being, quality of life, and work engagement and/or reduction in burnout, perceived stress, anxiety and depressive symptoms. However, many of these reported positive outcomes, were somewhat diluted by the limitations of the various study designs that is, no control group, usage of a waitlist style control group and/or lack of postintervention follow-up surveys. Despite this, healthcare institutions can implement interventions pertaining to mindfulness-based education, promoting positive mindsets or organisational changes that are shown to illicit positive results in the well-being of their staff. Employers must also address the bigger picture for healthcare worker well-being. A short-term inconvenience, can cultivate an environment condusive to improved well-being and reduced burnout, thereby fostering long-term productivity and retention of staff.

## Limitations and future research

Due to the large variation in study designs and data collection methods implemented, quantitative meta-analysis or comprehensive comparison of all study findings was not possible. Theoretical and practical implementations of the results are therefore complicated by the marked heterogeneity in intervention types, intervention timeframes, participant groups and conduction of postintervention follow-ups. This review was also limited by the lack of organisational studies that met the inclusion criteria. For example, several studies that implemented interventions involving the use of medical scribes or the electronic health record were excluded from this review as they did not focus on well-being as a primary outcome or did not use validated measures of well-being. Twenty-six of the thirty-three intervention studies reviewed opted to implement employee relaxation techniques to manage symptoms of occupational stress in the individual. With most studies adopting this one-dimensional view to employee well-being, it is difficult to accurately comment on the overall impact of well-being strategies for healthcare workers. Future research is needed to implement more primary or proactive organisational well-being interventions for healthcare workers, using robust study designs including appropriate control groups as well as further data collection beyond the conclusion of the intervention timeframe.
