<abstract><p><bold>Background:</bold> The COVID-19 pandemic has had a significant impact on the mental health of healthcare workers (HCWs) particularly in low and middle-income countries (LMICs). This scoping review provides a summary of current evidence on the mental health consequences of COVID on HCWs.</p>
<p><bold>Methods:</bold> A scoping review was conducted searching PubMed and Embase for articles relevant to mental health conditions among HCWs during COVID-19. Relevant articles were screened and extracted to summarize key outcomes and findings.</p>
<p><bold>Results:</bold> A total of fifty-one studies were included in this review. Depressive symptoms, anxiety symptoms, psychological trauma, insomnia and sleep quality, workplace burnout and fatigue, and distress were the main outcomes reviewed. Most studies found a high number of symptoms endorsed for depression, anxiety, and other conditions. We found differences in symptoms by sex, age, and HCW role, with female, younger-aged, frontline workers, and non-physician workers being affected more than other subgroups.</p>
<p><bold>Conclusion:</bold> This review highlights the existing burden of mental health conditions reported by HCWs during COVID-19.

<title>Introduction</title>
<p>From January to August 2020, over 800,000 people have died due to the COVID-19 pandemic, and health departments confirmed more than 24 million cases worldwide (<xref ref-type="bibr" rid="B1">1</xref>). The high transmission rate of SARS-CoV-2 and the severity of illness associated with COVID-19 have severely strained healthcare systems globally. The media and researchers continue to monitor and report the availability of hospital space, equipment, and treatment supplies (<xref ref-type="bibr" rid="B2">2</xref>). Shortages of personal protective equipment (PPE) and ventilators have been widely discussed in the literature (<xref ref-type="bibr" rid="B3">3</xref>, <xref ref-type="bibr" rid="B4">4</xref>). The World Health Organization (WHO) has also issued guidance around managing such shortages by recommending reasonable and appropriate usage of PPE (<xref ref-type="bibr" rid="B5">5</xref>).</p>
<p>An equally important issue is the severe threat to the well-being of healthcare workers (HCWs) during this pandemic. HCWs currently comprise the most critical sector of the workforce at the frontlines of testing and treatment for COVID-19 as well as covering other essential health services. They are at an unusually high risk of exposure to infection, and they are also at high risk of developing mental and behavioral disorders due to the high psychological toll of their intensive work in managing this highly infectious virus and grieving deaths of their colleagues (<xref ref-type="bibr" rid="B6">6</xref>, <xref ref-type="bibr" rid="B7">7</xref>). Several studies and reviews have examined the psychological effects of the COVID-19 pandemic on HCWs (<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" rid="B9">9</xref>). HCWs experience symptoms of depression and anxiety, sleep problems, burnout, and general psychological distress (<xref ref-type="bibr" rid="B10">10</xref>&#x02013;<xref ref-type="bibr" rid="B12">12</xref>). Understandably, at this stage in the pandemic existing studies show considerable variation in sampling methods and measurement of mental health outcomes. Nevertheless, emerging differences in mental disorder prevalence by sex and worker type may be of public health significance and warrant closer review (<xref ref-type="bibr" rid="B12">12</xref>).</p>
<p>Although HCWS across the world are currently overwhelmed by the demands of care for COVID-19 patients, the impact of the pandemic on the mental health of HCWs holds significance for low and middle-income countries (LMICS) in particular. Health systems in LMICs typically do not effectively incorporate continued care modalities for chronic conditions in comparison to high-income countries (HICs). Mental healthcare services for HCWs in particular are also far less accessible in LMICs than in HICs. The onset of COVID-19 has now resulted in a tremendous increase in demand for care in health systems that are already taxed with a higher burden of acute care compared to HICs. Adequate equipment and infrastructure to treat those with complex and intensive care needs are limited in supply. Therefore, LMICs have to navigate a complex trade-off&#x02014;preventing transmission, managing existing cases, as well as keeping their health systems and economies on track. Given these challenges LMICs face, supporting the well-being of HCWs is essential to maximizing benefits to those who need their services in both the short and long term.</p>
<p>Given the rapidly evolving nature of the evidence, we provide an update of the current evidence base on HCW mental health in LMICs. We review evidence from all locations but use our findings to guide recommendations for LMICs. This scoping review aims to (a) summarize emerging themes and results from key quantitative and qualitative evidence published between December 2019 and June 2020 on the psychological consequences of COVID-19 on HCWs, and (b) use the updated evidence base to provide a set of broad recommendations for mental health support for HCWs in LMICs. Findings highlighted here may guide the implementation of workplace interventions in low-resourced healthcare settings and help policymakers and health ministries develop mitigation policies and programs supporting the mental health of HCWs.</p>

<title>HCW Case Definition</title>
<p>For the purpose of this scoping review, we adhered to the Centers for Disease Control and Prevention (CDC) definition of HCWs which includes physicians, nurses, emergency medical personnel, dental professionals and students, medical and nursing students, laboratory technicians, pharmacists, hospital volunteers, and administrative staff (<xref ref-type="bibr" rid="B13">13</xref>).</p>
</sec>
<sec>
<title>Search Strategy</title>
<p>A scoping review was conducted using PubMed and Embase (Dec 2019&#x02013;June 2020) to broadly search for studies relevant to mental health in the context of COVID-19. Details of the search strings are in the <xref ref-type="supplementary-material" rid="SM1">Appendix</xref>. Papers on mental health conditions among HCWs were then screened and selected for this review. According to out inclusion criteria, papers were included if they reported any quantitative or qualitative data on mental disorders or symptoms and other related conditions among healthcare workers such as psychological trauma, distress, and workplace burnout. According to our exclusion criteria, papers were excluded if they did not provide pertinent information on mental health outcomes among HCWs or were not relevant to mental health during COVID-19. Selected studies were screened and information on study characteristics and outcomes reported were extracted. Findings from our review were then summarized by study methodology, outcomes, and HCW group in the results section below. MM, MR, and MK screened studies. MM and MR extracted data from selected studies. Any questions around study eligibility were jointly discussed and resolved by MM, MR, and MK. MM summarized findings from the final list of studies. The PRISMA study selection flowchart is provided in <xref ref-type="fig" rid="F1">Figure 1</xref>.</p>

<title>Results</title>
<p>A total of 51 studies were selected for this review. <xref ref-type="table" rid="T1">Table 1</xref> shows the countries represented in these studies. A majority, 61% of selected studies, originated from China. Based on World Bank Income level classifications, 72.5% of the studies were from Low and Middle Income Countries (LMICs). The sample size of included studies ranged from 52 to 14825 with a median sample size of 548. Of the 39 studies that reported data on the distribution of HCWs by sex, the median proportion of female HCWs was 64%. However, more than half the sample comprised female HCWs in 79% of these studies. All HCWs (physicians, nurses, and other workers) were represented in 78% of studies. Approximately 6% of studies reported exclusively on non-physician samples (example nurses, therapists) and 16% reported exclusively on physicians. Frontline or first-line medical workers (FMW), who typically are first responders to COVID-19 crises, are mentioned in the sample descriptions of nine studies.</p>

<p>The studies predominantly made use of a cross-sectional study design (88% of studies). Nearly all studies used a convenience sampling strategy and online data collection methods. Symptoms of anxiety (65% of studies), depression (57% of studies), and distress (37% of studies) were the most commonly studied conditions. The Patient Health Questionnaire (PHQ) (33% of studies) and the Generalized Anxiety Disorder Scale (GAD) (29% of studies) were the most commonly used instruments to measure symptoms of depression and anxiety, respectively.</p>
<sec>
<title>Anxiety Symptoms</title>
<p>HCWs frequently reported symptoms of anxiety (<xref ref-type="bibr" rid="B14">14</xref>, <xref ref-type="bibr" rid="B39">39</xref>, <xref ref-type="bibr" rid="B47">47</xref>, <xref ref-type="bibr" rid="B50">50</xref>, <xref ref-type="bibr" rid="B57">57</xref>, <xref ref-type="bibr" rid="B60">60</xref>). Anxiety was frequently associated with lowered sleep quality and insomnia and was common among those living with infants or elderly family members (<xref ref-type="bibr" rid="B32">32</xref>, <xref ref-type="bibr" rid="B47">47</xref>, <xref ref-type="bibr" rid="B58">58</xref>, <xref ref-type="bibr" rid="B61">61</xref>). Severe anxiety was associated with being in direct treatment contact with COVID-19 and the lack of adequate personal protective equipment (PPE) (<xref ref-type="bibr" rid="B32">32</xref>, <xref ref-type="bibr" rid="B36">36</xref>). Differences by age were also reported, with younger HCWs experiencing higher levels of anxiety compared to older age groups (<xref ref-type="bibr" rid="B30">30</xref>, <xref ref-type="bibr" rid="B44">44</xref>, <xref ref-type="bibr" rid="B45">45</xref>). Differences between male and female HCWs were also found, with women experiencing more symptoms of anxiety compared to men (<xref ref-type="bibr" rid="B20">20</xref>, <xref ref-type="bibr" rid="B22">22</xref>, <xref ref-type="bibr" rid="B24">24</xref>, <xref ref-type="bibr" rid="B30">30</xref>, <xref ref-type="bibr" rid="B32">32</xref>, <xref ref-type="bibr" rid="B44">44</xref>, <xref ref-type="bibr" rid="B45">45</xref>, <xref ref-type="bibr" rid="B64">64</xref>). Studies that examined mental health outcomes before and during the COVID-19 outbreak found a significant increase in reported anxiety symptoms in the outbreak period compared to the non-outbreak period (<xref ref-type="bibr" rid="B19">19</xref>, <xref ref-type="bibr" rid="B34">34</xref>, <xref ref-type="bibr" rid="B57">57</xref>).</p>
<p>Differences by HCW role: Differences in anxiety symptoms were also reported by HCW role and proximity to patients with COVID-19. In a study examining mental health conditions among physicians, nurses, and other professionals, nurses, and trainees reported higher anxiety than physicians (<xref ref-type="bibr" rid="B27">27</xref>). Similar findings are reported elsewhere with HCWs in non-physician roles such as nurses experiencing greater anxiety than those in physician roles (<xref ref-type="bibr" rid="B20">20</xref>, <xref ref-type="bibr" rid="B29">29</xref>, <xref ref-type="bibr" rid="B62">62</xref>, <xref ref-type="bibr" rid="B64">64</xref>). Front-line medical workers who are typically required to respond to COVID-19 emergencies experience higher levels of anxiety compared to non-frontline HCWs (<xref ref-type="bibr" rid="B28">28</xref>, <xref ref-type="bibr" rid="B51">51</xref>, <xref ref-type="bibr" rid="B55">55</xref>). HCWs in patient care roles experience higher anxiety than those in non-patient care roles or administrative roles (<xref ref-type="bibr" rid="B37">37</xref>, <xref ref-type="bibr" rid="B53">53</xref>). Similarly, those working in ICU wards reported greater anxiety compared to those who worked in isolation wards or other departments (<xref ref-type="bibr" rid="B45">45</xref>).</p>
</sec>
<sec>
<title>Depressive Symptoms</title>
<p>Symptoms of depression are highly prevalent among HCWs. Similar to anxiety symptoms, depressive symptoms were also associated with poor sleep quality and insomnia (<xref ref-type="bibr" rid="B47">47</xref>, <xref ref-type="bibr" rid="B52">52</xref>, <xref ref-type="bibr" rid="B61">61</xref>). Moderate to severe depressive symptoms were also linked to higher access to COVID information, lack of adequate PPE, and treating more COVID-19 patients (<xref ref-type="bibr" rid="B15">15</xref>). Studies that prospectively evaluated mental health outcomes found a significant increase in symptoms of depression in the outbreak period compared to the non-outbreak period (<xref ref-type="bibr" rid="B19">19</xref>, <xref ref-type="bibr" rid="B34">34</xref>, <xref ref-type="bibr" rid="B57">57</xref>).</p>
<p>Several studies showed that younger age was associated with a higher number of reported depressive symptoms (<xref ref-type="bibr" rid="B31">31</xref>, <xref ref-type="bibr" rid="B35">35</xref>, <xref ref-type="bibr" rid="B44">44</xref>, <xref ref-type="bibr" rid="B45">45</xref>, <xref ref-type="bibr" rid="B48">48</xref>). Female HCWs reported experiencing a higher severity of depressive symptoms than males in several studies that examined differences by sex (<xref ref-type="bibr" rid="B24">24</xref>, <xref ref-type="bibr" rid="B31">31</xref>&#x02013;<xref ref-type="bibr" rid="B33">33</xref>, <xref ref-type="bibr" rid="B44">44</xref>, <xref ref-type="bibr" rid="B45">45</xref>, <xref ref-type="bibr" rid="B64">64</xref>) with the exception of one study that reported higher depressive symptom severity in male HCWs compared to female counterparts (<xref ref-type="bibr" rid="B20">20</xref>). A study of otolaryngology physicians found no sex differences in depressive symptoms among HCWs (<xref ref-type="bibr" rid="B22">22</xref>).</p>
<p>Reported depressive symptoms also differed by healthcare roles and level of professional experience. A prospective cohort of first-year trainee physicians in China reported significant increases in depressive symptom severity during the COVID-19 outbreak (<xref ref-type="bibr" rid="B34">34</xref>). Nurses and other HCWs in non-physician roles experienced greater depressive symptom severity compared to HCWs in physician roles (<xref ref-type="bibr" rid="B20">20</xref>, <xref ref-type="bibr" rid="B27">27</xref>, <xref ref-type="bibr" rid="B28">28</xref>, <xref ref-type="bibr" rid="B33">33</xref>, <xref ref-type="bibr" rid="B62">62</xref>, <xref ref-type="bibr" rid="B64">64</xref>). Those in government health services reported more depressive symptoms compared to other sectors such as private practice or NGOs (<xref ref-type="bibr" rid="B31">31</xref>). Proximity to COVID-19 crises also affect depression severity (<xref ref-type="bibr" rid="B45">45</xref>). A study of frontline medical workers (FMWs) in China found that over 45% of FMWs experienced symptoms of depression (<xref ref-type="bibr" rid="B51">51</xref>). Several studies showed that FMWs reported greater depressive symptom severity when compared to non-FMWs (<xref ref-type="bibr" rid="B28">28</xref>, <xref ref-type="bibr" rid="B33">33</xref>, <xref ref-type="bibr" rid="B55">55</xref>). Similarly, HCWs in medical roles experience greater depression symptom severity than those in non-medical roles in healthcare (<xref ref-type="bibr" rid="B53">53</xref>).</p>
</sec>
<sec>
<title>Insomnia and Sleep Quality</title>
<p>Insomnia and poor sleep quality were commonly reported by HCWs alongside depression, anxiety and stress (<xref ref-type="bibr" rid="B15">15</xref>, <xref ref-type="bibr" rid="B17">17</xref>, <xref ref-type="bibr" rid="B33">33</xref>, <xref ref-type="bibr" rid="B47">47</xref>, <xref ref-type="bibr" rid="B59">59</xref>). Similar to depression and anxiety, there are differences that emerged by sex and occupational role. A study conducted among hospital staff in China between January and February 2020 showed that females reported higher rates of insomnia compared to males (<xref ref-type="bibr" rid="B61">61</xref>). The same study also found that nurses experienced greater insomnia severity (ascertained using the Insomnia Severity Index&#x02013;which measures the severity and frequency of the sleep disorder insomnia) compared to doctors and other medical staff (<xref ref-type="bibr" rid="B61">61</xref>). Similar findings were also reported in a study of mental health outcomes among HCWs in Italy: nurses and healthcare assistants reported greater insomnia severity than physicians, general practitioners and other medical professions (<xref ref-type="bibr" rid="B44">44</xref>). Proximity to COVID-19 cases was also associated with poor sleep quality (ascertained using the Pittsburgh Sleep Quality Index&#x02013;which measures recent deviances in usual sleeping habits) and insomnia. Frontline workers and medical HCWs experienced worse sleep quality and higher insomnia severity than non-frontline workers and non-medical HCWs (<xref ref-type="bibr" rid="B41">41</xref>, <xref ref-type="bibr" rid="B53">53</xref>, <xref ref-type="bibr" rid="B55">55</xref>).</p>
</sec>
<sec>
<title>Other Related Conditions (Distress, Psychological Trauma, and Burnout)</title>
<p>The studies in this review also reported additional outcomes such as distress, psychological trauma, and workplace burnout. High levels of workplace exhaustion and fatigue were prevalent (<xref ref-type="bibr" rid="B38">38</xref>, <xref ref-type="bibr" rid="B42">42</xref>). Younger HCWs reported higher prevalence of symptoms of psychological trauma and distress compared to older HCWs (<xref ref-type="bibr" rid="B44">44</xref>, <xref ref-type="bibr" rid="B48">48</xref>). Females, more than males, reported psychological trauma, burnout due to stressful work conditions, and distress (<xref ref-type="bibr" rid="B22">22</xref>, <xref ref-type="bibr" rid="B29">29</xref>, <xref ref-type="bibr" rid="B40">40</xref>, <xref ref-type="bibr" rid="B59">59</xref>, <xref ref-type="bibr" rid="B64">64</xref>) though one study reported greater psychological trauma symptoms among male HCWs (<xref ref-type="bibr" rid="B48">48</xref>). These sex differences also existed among physicians, with female physicians reporting higher burnout than their male counterparts (<xref ref-type="bibr" rid="B22">22</xref>, <xref ref-type="bibr" rid="B43">43</xref>). Differences by HCW role were reported with nurses and healthcare assistants reporting greater distress than those in physician roles (<xref ref-type="bibr" rid="B44">44</xref>, <xref ref-type="bibr" rid="B48">48</xref>). Nurses, trainees, and non-physicians reported also higher stress (<xref ref-type="bibr" rid="B20">20</xref>, <xref ref-type="bibr" rid="B27">27</xref>, <xref ref-type="bibr" rid="B59">59</xref>, <xref ref-type="bibr" rid="B64">64</xref>). Among physician roles, resident physicians experienced greater burnout than attending physicians and physicians in branches of general surgery, gynecology, and orthopedics also reported higher burnout (<xref ref-type="bibr" rid="B22">22</xref>, <xref ref-type="bibr" rid="B23">23</xref>). In terms of work duration, permanent workers reported greater burnout and fatigue compared to temporary workers (<xref ref-type="bibr" rid="B43">43</xref>).</p>

<title>Discussion</title>
<p>Our findings highlight the high prevalence frequency of anxiety, depressive symptoms, insomnia, burnout, and distress that HCWs have experienced during the COVID-19 pandemic and are consistent with existing reviews (<xref ref-type="bibr" rid="B12">12</xref>, <xref ref-type="bibr" rid="B65">65</xref>&#x02013;<xref ref-type="bibr" rid="B70">70</xref>). Reviews published on this topic either cover shorter timeframes compared to this current review or report on studies only from China. Meta-analytic approaches used by some reviews may be subject to important methodological limitations. For instance, an earlier meta-analysis by Pappa et al. synthesized results from 13 studies to provide prevalence estimates of depression, anxiety, and insomnia (<xref ref-type="bibr" rid="B12">12</xref>). However, the paper also highlights limited data availability and important methodological sources of variation that contribute to between-study heterogeneity. Similar concerns around the lack of validated mental health outcome measures and appropriate comparisons to pre-outbreak time periods are also cited by Thombs et al. (<xref ref-type="bibr" rid="B71">71</xref>).</p>
<p>Our current review includes 51 studies with substantial variation in methodology and results reported which precluded the use of a meta-analytic approach and made a narrative review of results most suitable for this work. These studies employed a variety of instruments and used different cutoff thresholds to assess severity. Notably, the magnitude and severity of reported mental health outcomes may vary based on the validity and sensitivity of the measurement tools. The selection criteria of HCW samples also varied between studies, and HCWs&#x00027; degree of exposure to patients with COVID-19 care also differed. It is likely that the degree of proximity to COVID-19 treatment may determine the extent to which HCWs experience grief, fear, anxiety, or concerns about their personal safety.</p>
<p>Some limitations are important to note. First, our search was conducted from December 2019 to June 2020 which covers &#x0007E;7 months of the COVID-19 pandemic. Given the rapidly evolving literature in this area at present, it is possible that new studies may have been indexed later that we were unable to include in this review. Second, the timeline for this rapid review allowed for the search of only two electronic databases. Finally, there were very few studies from lower-middle income countries that could be used in our report indicating a need for more studies from these locations to improve the quality of available evidence.</p>
<p>Despite the methodological variation present in the studies reviewed, there are important themes that are predominant in the evidence thus far. Significant differential patterns by age, sex, and HCW role have emerged. Younger, female, non-physician HCWS, and frontline workers appear to be more vulnerable to poor mental health as seen in several studies reported above. Workplace burnout is also highly prevalent among these subgroups and is important to study further as it co-occurs with other mental health conditions such as depression (<xref ref-type="bibr" rid="B72">72</xref>). These differences based on demographics and work role are also observed in earlier reviews (<xref ref-type="bibr" rid="B12">12</xref>). It is important to note that the majority of non-physician HCWs are typically female, and it will be useful to disentangle the effects of sex and HCW role in future work. In our review, only 9 studies reported inclusion of frontline workers in their samples and 3 studies sampled non-physicians exclusively. Therefore, gaining a more comprehensive understanding of mental health in these subgroups will require additional studies. Nonetheless, such differences as seen in our review and elsewhere are likely to have varying consequences for HCWs in the larger context of workplace equity during major global health crises.</p>
<p>Support of HCW mental health in LMICs must be tailored from the perspective of these differences that could be potential harbingers of emerging disparities. These could likely place specific HCW subgroups (female HCWs, younger HCWs, non-physician workers) at a disproportionately higher risk for developing mental disorders. LMICs are known to experience challenges in investment in healthcare resources including inadequate personnel. Adaptations in healthcare delivery models such as repurposing of health facilities, task shifting without competency based trainings and supportive supervision, and redeployment from different departments to accommodate high patient volumes will inevitably place a greater burden on already vulnerable HCW subgroups. In addition to the burden of these stressors, HCWs are also likely to face economic changes such as exacerbated poverty and inequality that are projected to take place in LMICs due to the pandemic (<xref ref-type="bibr" rid="B73">73</xref>). Therefore, these have important implications for future research and intervention development. International institutes have developed guidelines to address mental health burden of HCWs. The United Nations and WHO published guidelines and recommendations on mitigating the mental health impact of COVID-19 on HCWs (<xref ref-type="bibr" rid="B74">74</xref>, <xref ref-type="bibr" rid="B75">75</xref>). The National Academy of Medicine has also published strategies to support mental health of HCWs and clinicians during COVID-19 (<xref ref-type="bibr" rid="B76">76</xref>). In the context of the evidence presented above and by these major organizations, some general guidelines and recommendations are provided below in <xref ref-type="table" rid="T2">Tables 2A</xref>, <xref ref-type="table" rid="T3">B</xref>. These are aimed at improving both the generation of high quality evidence through research as well as intervention strategies to implement in practice for the support of HCWs&#x00027; mental health in LMICs.</p>

<title>Conclusion</title>
<p>HCWs experience considerable adverse mental health outcomes in the context of COVID-19. Findings summarized in this review can inform approaches to monitoring and data collection for mental health outcomes among HCWs in LMICs. These findings can aid the tailoring of interventions and support strategies implemented at the institutional and national levels to mitigate and manage mental health conditions among HCWs in LMICs with a specific focus on vulnerable HCW subgroups.</p>
