Comprehensive occupational health services for healthcare workers in Zimbabwe during the SARS-CoV-2 pandemic.

BACKGROUND: Healthcare workers are disproportionately affected by COVID-19. In low- and middle- income countries, they may be particularly impacted by underfunded health systems, lack of personal protective equipment, challenging working conditions and barriers in accessing personal healthcare. METHODS: In this cross-sectional study, occupational health screening was implemented at the largest public sector medical centre in Harare, Zimbabwe, during the "first wave" of the country's COVID-19 epidemic. Clients were voluntarily screened for symptoms of COVID-19, and if present, offered a SARS-CoV-2 nucleic acid detection assay. In addition, measurement of height, weight, blood pressure and HbA1c, HIV and TB testing, and mental health screening using the Shona Symptom Questionnaire (SSQ-14) were offered. An interviewer-administered questionnaire ascertained client knowledge and experiences related to COVID-19. RESULTS: Between 27th July and 30th October 2020, 951 healthcare workers accessed the service; 210 (22%) were tested for SARS-CoV-2, of whom 12 (5.7%) tested positive. Clients reported high levels of concern about COVID-19 which declined with time, and faced barriers including lack of resources for infection prevention and control. There was a high prevalence of largely undiagnosed non-communicable disease: 61% were overweight or obese, 34% had a blood pressure of 140/90mmHg or above, 10% had an HbA1c diagnostic of diabetes, and 7% had an SSQ-14 score consistent with a common mental disorder. Overall 8% were HIV-positive, with 97% previously diagnosed and on treatment. CONCLUSIONS: Cases of SARS-CoV-2 in healthcare workers mirrored the national epidemic curve. Implementation of comprehensive occupational health services during a pandemic was feasible, and uptake was high. Other comorbidities were highly prevalent, which may be risk factors for severe COVID-19 but are also important independent causes of morbidity and mortality. Healthcare workers are critical to combatting COVID-19; it is essential to support their physical and psychological wellbeing during the pandemic and beyond

Evaluation of a comprehensive health check offered to frontline health workers in Zimbabwe

Health workers are essential for a functioning healthcare system, and their own health is often not addressed. During the COVID-19 pandemic health workers were at high risk of SARS-CoV-2 infection whilst coping with increased healthcare demand. Here we report the development, implementation, and uptake of an integrated health check combining SARS-CoV-2 testing with screening for other communicable and non-communicable diseases for health workers in Zimbabwe during the COVID-19 pandemic. Health checks were offered to health workers in public and private health facilities from July 2020 to June 2022. Data on the number of health workers accessing the service and yield of screening was collected. Workshops and in-depth interviews were conducted to explore the perceptions and experiences of clients and service providers. 6598 health workers across 48 health facilities accessed the service. Among those reached, 5215 (79%) were women, the median age was 37 (IQR: 29-44) years and the largest proportion were nurses (n = 2092, 32%). 149 (2.3%) healthcare workers tested positive for SARS-CoV-2. Uptake of screening services was almost 100% for all screened conditions except HIV. The most common conditions detected through screening were elevated blood pressure (n = 1249; 19%), elevated HbA1c (n = 428; 7.7%) and common mental disorder (n = 645; 9.8%). Process evaluation showed high acceptability of the service. Key enablers for health workers accessing the service included free and comprehensive service provision, and availability of reliable point-of-care screening methods. Implementation of a comprehensive health check for health workers was feasible, acceptable, and effective, even during a pandemic. Conventional occupational health programmes focus on infectious diseases. In a society where even health workers cannot afford health care, free comprehensive occupational health services may address unmet needs in prevention, diagnosis, and treatment for chronic non-communicable conditions

Early risk assessment in paediatric and adult household contacts of confirmed tuberculosis cases by novel diagnostic tests (ERASE-TB): protocol for a prospective, non-interventional, longitudinal, multicountry cohort study.

INTRODUCTION: The WHO End-TB Strategy calls for the development of novel diagnostics to detect tuberculosis (TB) earlier and more accurately. Better diagnostics, together with tools to predict disease progression, are critical for achieving WHO End-TB targets. The Early Risk Assessment in TB Contacts by new diagnoStic tEsts (ERASE-TB) study aims to evaluate novel diagnostics and testing algorithms for early TB diagnosis and accurate prediction of disease progression among household contacts (HHCs) exposed to confirmed index cases in Mozambique, Tanzania and Zimbabwe. METHODS AND ANALYSIS: A total of 2100 HHCs (aged ≥10 years) of adults with microbiologically-confirmed pulmonary TB will be recruited and followed up at 6-month intervals for 18–24 months. At each time point, a WHO symptom screen and digital chest radiograph (dCXR) will be performed, and blood and urine samples will be collected. Individuals screening positive (WHO symptom screen or dCXR) will be requested to provide sputum for Xpert MTB/Rif Ultra. At baseline, HHCs will also be screened for HIV, diabetes (HbA1c), chronic lung disease (spirometry), hypertension and anaemia. Study outcomes will be coprevalent TB (diagnosed at enrolment), incident TB (diagnosed during follow-up) or no TB at completion of follow-up. Novel diagnostics will be validated using fresh and biobanked samples with a nested case–control design. Cases are defined as HHCs diagnosed with TB (for early diagnosis) or with incident TB (for prediction of progression) and will be matched by age, sex and country to HHCs who remain healthy (controls). Statistical analyses will include assessment of diagnostic accuracy by constructing receiver operating curves and calculation of sensitivity and specificity ETHICS AND DISSEMINATION: ERASE-TB has been approved by regulatory and ethical committees in each African country and by each partner organisation. Consent, with additional assent for participants <18 years, is voluntary. Attestation by impartial witnesses is sought in case of illiteracy. Confidentiality of participants is being maintained throughout. Study findings will be presented at scientific conferences and published in peer-reviewed international journals.

Prevalence of chronic conditions and multimorbidity among healthcare workers in Zimbabwe:Results from a screening intervention

Non-communicable diseases (NCDs) are the leading causes of death globally, with most deaths occurring in low and middle income countries [1]. In particular, diabetes, hypertension, and their consequences, are among the top five causes of death and disability, with their prevalence and impact projected to increase dramatically in the coming decades. In southern Africa, the rapidly increasing impact of NCDs on mortality and years lived with disability is occurring in a context of ongoing high prevalence of HIV, tuberculosis (TB) and nutritional disorders, and a persisting substantial burden of other infections [2]. This presents considerable challenges to fragile health systems.Shared social and structural risk factors, together with shared biological pathways, mean that chronic conditions coexist within individuals: this phenomenon of multimorbidity, commonly defined as two or more physical or mental health conditions of long duration, magnifies the physical, psychological, social and financial consequences of ill health [3]. The last decade has seen growing awareness of multimorbidity with a suggestion of high prevalence of multimorbidity in Africa (pooled prevalence among adults 28% from a systematic review) [4]. However, population-based data are only available from a few countries and have usually relied on self-reported conditions [4,5], an approach which is likely to underestimate prevalence given that many conditions are undiagnosed [6,7].The healthcare workforce is the core of any health system: maintaining staff wellbeing is critically important for population health generally, for achieving Sustainable Development Goals, and for our ability to combat future pandemics [8]. Africa faces a healthcare workforce crisis, with a projected shortfall of 6.1 million healthcare workers by 2030 [9]. Alongside a severe HIV epidemic, Zimbabwe has experienced a sustained economic crisis that has severely impacted the health system and resulted in a mass exodus of health workers [10]. The infrastructure for identifying and managing NCDs is weak, resulting in underdiagnosis and undertreatment [11]. As a result of a depleted healthcare workforce, Zimbabwe has been added to the WHO health workforce support and safeguards list [12].It is likely that chronic diseases and multimorbidity impact on the ability of healthcare workers to continue to work, resulting in illness-related absences, requiring adjustment of work roles, or leading to early retirement. In countries affected by economic migration, staff who remain are generally older and therefore likely to be at higher risk of multimorbidity; increasing the impact of multimorbidity on human resources for health [13]. There are no studies on the prevalence or impact of multimorbidity among healthcare workers in Africa nor of multimorbidity among the general Zimbabwean population. One small study reported on the prevalence of hypertension among healthcare workers in Africa; whilst more reports have considered mental health in the context of the COVID-19 pandemic. Zimbabwean NCD prevalence estimates are either almost 20 years old or restricted to people attending HIV clinics [14].In the context of the COVID-19 pandemic, we implemented comprehensive health check-ups for healthcare workers in Zimbabwe, to provide access to SARS-CoV-2 testing and to address underlying risk factors for severe COVID-19 (ICAROZ [Impact of the COVID-19 pandemic on healthcare workers and the healthcare system in Zimbabwe]). In this analysis, we aimed to describe the epidemiology of both multimorbidity and the prevalence of individual chronic conditions, among healthcare workers in Zimbabwe

Psychological distress among healthcare workers accessing occupational health services during the COVID-19 pandemic in Zimbabwe.

BACKGROUND: Healthcare workers (HCWs) have experienced anxiety and psychological distress during the COVID-19 pandemic. We established and report findings from an occupational health programme for HCWs in Zimbabwe that offered screening for SARS-CoV-2 with integrated screening for comorbidities including common mental disorder (CMD) and referral for counselling. METHODS: Quantitative outcomes were fearfulness about COVID-19, the Shona Symptom Questionnaire (SSQ-14) score (cutpoint 8/14) and the number and proportion of HCWs offered referral for counselling, accepting referral and counselled. We used chi square tests to identify factors associated with fearfulness, and logistic regression was used to model the association of fearfulness with wave, adjusting for variables identified using a DAG. Qualitative data included 18 in-depth interviews, two workshops conducted with HCWs and written feedback from counsellors, analysed concurrently with data collection using thematic analysis. RESULTS: Between 27 July 2020-31 July 2021, spanning three SARS-CoV-2 waves, the occupational health programme was accessed by 3577 HCWs from 22 facilities. The median age was 37 (IQR 30-43) years, 81.9% were women, 41.7% said they felt fearful about COVID-19 and 12.1% had an SSQ-14 score ≥ 8. A total of 501 HCWs were offered referral for counselling, 78.4% accepted and 68.9% had ≥1 counselling session. Adjusting for setting and role, wave 2 was associated with increased fearfulness over wave 1 (OR = 1.26, 95% CI 1.00-1.60). Qualitative data showed high levels of anxiety, psychosomatic symptoms and burnout related to the pandemic. Mental wellbeing was affected by financial insecurity, unmet physical health needs and inability to provide quality care within a fragile health system. CONCLUSIONS: HCWs in Zimbabwe experience a high burden of mental health symptoms, intensified by the COVID-19 pandemic. Sustainable mental health interventions must be multisectoral addressing mental, physical and financial wellbeing

Exploring COVID-19 vaccine uptake among healthcare workers in Zimbabwe: A mixed methods study.

With COVID-19 no longer categorized as a public health emergency of international concern, vaccination strategies and priority groups for vaccination have evolved. Africa Centres for Diseases Prevention and Control proposed the '100-100-70%' strategy which aims to vaccinate all healthcare workers, all vulnerable groups, and 70% of the general population. Understanding whether healthcare workers were reached during previous vaccination campaigns and what can be done to address concerns, anxieties, and other influences on vaccine uptake, will be important to optimally plan how to achieve these ambitious targets. In this mixed-methods study, between June 2021 and July 2022 a quantitative survey was conducted with healthcare workers accessing a comprehensive health check in Zimbabwe to determine whether and, if so, when they had received a COVID-19 vaccine. Healthcare workers were categorized as those who had received the vaccine 'early' (before 30.06.2021) and those who had received it 'late' (after 30.06.2021). In addition, 17 in-depth interviews were conducted to understand perceptions and beliefs about COVID-19 vaccines. Of the 3,086 healthcare workers employed at 43 facilities who participated in the study, 2,986 (97%, 95% CI [92%-100%]) reported that they had received at least one vaccine dose. Geographical location, older age, higher educational attainment and having a chronic condition was associated with receiving the vaccine early. Qualitatively, (mis)information, infection risk perception, quasi-mandatory vaccination requirements, and legitimate concerns such as safety and efficacy influenced vaccine uptake. Meeting the proposed 100-100-70 target entails continued emphasis on strong communication while engaging meaningfully with healthcare workers' concerns. Mandatory vaccination may undermine trust and should not be a substitute for sustained engagement

Disease control status of chronic conditions and multimorbidity, in multiply imputed dataset (N = 5215 women / 1383 men).

Clients were considered to have a condition if they either self-reported or screened positive during the study. Screening positive was defined as follows. Hypertension: Systolic BP ≥140mmHg or diastolic BP ≥90mmgHg. Diabetes: ≥6.5%. Common mental disorder: Shona Symptom Questionnaire Score ≥8. In the plot of multimorbidity (right panel), included conditions are HIV, diabetes, hypertension, and common mental disorders. Multimorbidity is defined as two or more conditions coexisting in an individual (orange, yellow or red). Disease control is defined as having a previous history of the condition, but a normal result during screening (e.g., known diabetes but HbA1c <6.5% on testing). HIV control was not assessed, HIV on treatment is included as a ‘controlled’ condition in the multimorbidity figure.</p
