The longitudinal association of stressful life events with depression remission among SHARP trial participants with depression and hypertension or diabetes in Malawi.

Depressive disorders are leading contributors to morbidity in low- and middle-income countries and are particularly prevalent among people with non-communicable diseases (NCD). Stressful life events (SLEs) are risk factors for, and can help identify those at risk of, severe depressive illness requiring more aggressive treatment. Yet, research on the impact of SLEs on the trajectory of depressive symptoms among NCD patients indicated for depression treatment is lacking, especially in low resource settings. This study aims to estimate the longitudinal association of SLEs at baseline with depression remission achievement at three, six, and 12 months among adults with either hypertension or diabetes and comorbid depression identified as being eligible for depression treatment. Participants were recruited from 10 NCD clinics in Malawi from May 2019-December 2021. SLEs were measured by the Life Events Survey and depression remission was defined as achieving a Patient Health Questionaire-9 (PHQ-9) score <5 at follow-up. The study population (n = 737) consisted predominately of females aged 50 or higher with primary education and current employment. At baseline, participants reported a mean of 3.5 SLEs in the prior three months with 90% reporting ≥1 SLE. After adjustment, each additional SLE was associated with a lower probability of achieving depression remission at three months (cumulative incidence ratio (CIR) 0.94; 95% confidence interval: 0.90, 0.98, p = 0.002), six months (0.95; 0.92, 0.98, p = 0.002) and 12 months (0.96; 0.94, 0.99, p = 0.011). Re-expressed per 3-unit change, the probability of achieving depression remission at three, six, and 12 months was 0.82, 0.86, and 0.89 times lower per 3 SLEs (the median number of SLEs). Among NCD patients identified as eligible for depression treatment, recent SLEs at baseline were associated with lower probability of achieving depression remission at three, six, and 12 months. Findings suggest that interventions addressing SLEs during integrated NCD and depression care interventions (e.g., teaching and practicing SLE coping strategies) may improve success of depression treatment among adult patient populations in low-resource settings and may help identify those at risk of severe and treatment resistant depression.

Protocol for an evaluation of the initiation of an integrated longitudinal outpatient care model for severe chronic non-communicable diseases (PEN-Plus) at secondary care facilities (district hospitals) in 10 lower-income countries.

INTRODUCTION: The Package of Essential Noncommunicable Disease Interventions-Plus (PEN-Plus) is a strategy decentralising care for severe non-communicable diseases (NCDs) including type 1 diabetes, rheumatic heart disease and sickle cell disease, to increase access to care. In the PEN-Plus model, mid-level clinicians in intermediary facilities in low and lower middle income countries are trained to provide integrated care for conditions where services traditionally were only available at tertiary referral facilities. For the upcoming phase of activities, 18 first-level hospitals in 9 countries and 1 state in India were selected for PEN-Plus expansion and will treat a variety of severe NCDs. Over 3 years, the countries and state are expected to: (1) establish PEN-Plus clinics in one or two district hospitals, (2) support these clinics to mature into training sites in preparation for national or state-level scale-up, and (3) work with the national or state-level stakeholders to describe, measure and advocate for PEN-Plus to support development of a national operational plan for scale-up. METHODS AND ANALYSIS: Guided by Proctor outcomes for implementation research, we are conducting a mixed-method evaluation consisting of 10 components to understand outcomes in clinical implementation, training and policy development. Data will be collected through a mix of quantitative surveys, routine reporting, routine clinical data and qualitative interviews. ETHICS AND DISSEMINATION: This protocol has been considered exempt or covered by central and local institutional review boards. Findings will be disseminated throughout the project's course, including through quarterly M&E discussions, semiannual formative assessments, dashboard mapping of progress, quarterly newsletters, regular feedback loops with national stakeholders and publication in peer-reviewed journals.

Development and piloting of a primary school-based salt reduction programme: Formative work and a process evaluation in rural and urban Malawi.

Excess salt intake is a major modifiable risk factor for cardiovascular disease. Promoting salt reduction as part of routine school-health programming may be a pragmatic way to address this risk factor early in the life course but has not been tested in sub-Saharan Africa (SSA). Here we describe the formative work with stakeholders and process evaluation of pilot work to develop a school-based salt reduction programme for children aged 11-14 years, in preparation for a cluster-randomised trial in rural/urban Malawi. Collection of observational data and documentary evidence (meeting minutes/field notes) from the earliest key stakeholder engagement with Malawi Ministries of Health, Education, Local Government and Rural Development and Malawi Institute of Education, and non-governmental stakeholders; and a series of semi-structured interviews and focus groups (with head teachers (n = 2); teachers (n = 4); parents (n = 30); and learners (n = 40)). Data was analysed thematically and conceptualised through a Normalization Process Theory lens. Formative work illustrated a range of administrative, technical, and practical issues faced during development of the programme; including allocation of stakeholder roles and responsibilities, harmonisation with pre-existing strategies and competing priorities, resources required for programme development, and design of effective teaching materials. While participants were positive about the programme, the process evaluation identified features to be refined including perceived challenges to participation, recommended adaptations to the content and delivery of lessons, and concerns related to quantity/quality of learning resources provided. This study demonstrates the importance of comprehensive, sustained, and participatory stakeholder engagement in the development of a novel school health programme in SSA; and highlights the factors that were critical to successfully achieving this. We also demonstrate the value of detailed process evaluation in informing development of the programme to ensure that it was feasible and relevant to the context prior to evaluation through a cluster-randomised trial.

Champion and audit and feedback strategy fidelity and their relationship to depression intervention fidelity: A mixed method study.

Background: Globally, mental health disorders rank as the greatest cause of disability. Low and middle-income countries (LMICs) hold a disproportionate share of the mental health burden, especially as it pertains to depression. Depression is highly prevalent among those with non-communicable diseases (NCDs), creating a barrier to successful treatment. While some treatments have proven efficacy in LMIC settings, wide dissemination is challenged by multiple factors, leading researchers to call for implementation strategies to overcome barriers to care provision. However, implementation strategies are often not well defined or documented, challenging the interpretation of study results and the uptake and replication of strategies in practice settings. Assessing implementation strategy fidelity (ISF), or the extent to which a strategy was implemented as designed, overcomes these challenges. This study assessed fidelity of two implementation strategies (a 'basic' champion strategy and an 'enhanced' champion + audit and feedback strategy) to improve the integration of a depression intervention, measurement based care (MBC), at 10 NCD clinics in Malawi. The primary goal of this study was to assess the relationship between the implementation strategies and MBC fidelity using a mixed methods approach. Methods: We developed a theory-informed mixed methods fidelity assessment that first combined an implementation strategy specification technique with a fidelity framework. We then created corresponding fidelity indicators to strategy components. Clinical process data and one-on-one in-depth interviews with 45 staff members at 6 clinics were utilized as data sources. Our final analysis used descriptive statistics, reflexive-thematic analysis (RTA), data merging, and triangulation to examine the relationship between ISF and MBC intervention fidelity. Results: Our mixed methods analysis revealed how ISF may moderate the relationship between the strategies and MBC fidelity. Leadership engagement and implementation climate were critical for clinics to overcome implementation barriers and preserve implementation strategy and MBC fidelity. Descriptive statistics determined champion strategy fidelity to range from 61 to 93% across the 10 clinics. Fidelity to the audit and feedback strategy ranged from 82 to 91% across the 5 clinics assigned to that condition. MBC fidelity ranged from 54 to 95% across all clinics. Although correlations between ISF and MBC fidelity were not statistically significant due to the sample of 10 clinics, associations were in the expected direction and of moderate effect size. A coefficient for shared depression screening among clinicians had greater face validity compared to depression screening coverage and functioned as a proximal indicator of implementation strategy success. Conclusion: Fidelity to the basic and enhanced strategies varied by site and were influenced by leadership engagement and implementation climate. Champion strategies may benefit from the addition of leadership strategies to help address implementation barriers outside the purview of champions. ISF may moderate the relationship between strategies and implementation outcomes.

Evaluating the validity of depression-related stigma measurement among diabetes and hypertension patients receiving depression care in Malawi: A mixed-methods analysis.

Mental illness stigma research is sparse in Malawi. Our team previously analyzed the reliability and statistical validity of a quantitative tool to measure depression-related stigma among participants with depressive symptoms using quantitative psychometric methods. This analysis aims to further evaluate the content validity of the stigma tool by comparing participants' quantitative responses with qualitative data. The SHARP project conducted depression screening and treatment at 10 noncommunicable disease clinics across Malawi from April 2019 through December 2021. Eligible participants were 18-65 years with depressive symptoms indicated by a PHQ-9 score ≥5. Questionnaires at each study timepoint included a vignette-based quantitative stigma instrument with three thematic domains: disclosure carryover (i.e., concerns about disclosure), treatment carryover (i.e., concerns about external stigma because of receiving depression treatment), and negative affect (i.e., negative attitudes about people having depression). Sub-scores were aggregated for each domain, with higher scores indicating greater stigma. To better understand participants' interpretation of this quantitative stigma questionnaire, we asked a subset of six participants a parallel set of questions in semi-structured qualitative interviews in a method similar to cognitive interviewing. Qualitative responses were linked with participants' most recent quantitative follow-up interviews using Stata 16 and NVivo software. Participants with lower quantitative stigma disclosure sub-scores had qualitative responses that indicated less stigma around disclosure, while participants with higher quantitative stigma sub-scores had qualitative responses indicating greater stigma. Similarly, in the negative affect and treatment carryover domains, participants had parallel quantitative and qualitative responses. Further, participants identified with the vignette character in their qualitative interviews, and participants spoke about the character's projected feelings and experiences based on their own lived experiences. The stigma tool was interpreted appropriately by participants, providing strong evidence for the content validity of the quantitative tool to measure these stigma domains.

The cross-sectional association of stressful life events with depression severity among patients with hypertension and diabetes in Malawi.

Depressive disorders are a leading cause of global morbidity and remain disproportionately high in low- and middle-income settings. Stressful life events (SLEs) are known risk factors for depressive episodes and worsened depressive severity, yet are under-researched in comparison to other depression risk factors. As depression is often comorbid with hypertension, diabetes, and other noncommunicable diseases (NCDs), research into this relationship among patients with NCDs is particularly relevant to increasing opportunities for integrated depression and NCD care. This study aims to estimate the cross-sectional association between SLEs in the three months preceding baseline interviews and baseline depressive severity among patients with at least mild depressive symptoms who are seeking NCD care at 10 NCD clinics across Malawi. SLEs were measured by the Life Events Survey and depressive severity (mild vs. moderate to severe) was measured by the Patient Health Questionnaire-9. The study population (n = 708) was predominately currently employed, grand multiparous (5-8 children) women with a primary education level. Two thirds (63%) had mild depression while 26%, 8%, and 3% had moderate, moderately severe, and severe depression, respectively. Nearly all participants (94%) reported at least one recent SLE, with the most common reported SLEs being financial stress (48%), relationship changes (45%), death of a family member or friend (41%), or serious illness of a family member or friend (39%). Divorce/separation, estrangement from a family member, losing source of income, and major new health problems were significant predictors of greater (moderate or severe) depressive severity compared to mild severity. Having a major new health problem or experiencing divorce/separation resulted in particularly high risk of more severe depression. After adjustment, each additional SLE was associated with a 9% increased risk of moderate or worse depressive severity compared to mild depressive severity (RR: 1.09; (95% CI: 1.05, 1.13), p<0.0001). Among patients with NCDs with at least mild depressive symptoms, SLEs in the prior 3 months were associated with greater depressive severity. While many SLEs may not be preventable, this research suggests that assessment of SLEs and teaching of positive coping strategies when experiencing SLEs may play an important role in integrated NCD and depression treatment models.

"Thandi should feel embarrassed": describing the validity and reliability of a tool to measure depression-related stigma among patients with depressive symptoms in Malawi.

PURPOSE: There are no validated tools in Malawi to measure mental health stigma. Accordingly, this study evaluates the validity and reliability of a short quantitative instrument to measure depression-related stigma in patients exhibiting depressive symptoms in Malawi. METHODS: The SHARP study began depression screening in 10 NCD clinics across Malawi in April 2019; recruitment is ongoing. Eligible participants were 18-65 years, had a patient health questionnaire (PHQ-9) score ≥ 5, and were new or current diabetes or hypertension patients. Participants completed a baseline questionnaire that measured depression-related stigma, depressive symptoms, and sociodemographic information. The stigma instrument included a vignette of a depressed woman named Thandi, and participants rated their level of agreement with statements about Thandi's situation in nine prompts on a 5-point Likert scale. Inter-item reliability was assessed with Cronbach's alpha. Exploratory factor analysis (EFA) was used to assess structural validity, and OLS regression models were used to assess convergent and divergent validity between measured levels of depression-related stigma and covariates. RESULTS: The analysis of patient responses (n = 688) to the stigma tool demonstrated acceptable inter-item reliability across all scales and subsequent subscales of the instrument, with alpha values ranging from 0.70 to 0.87. The EFA demonstrated clustering around three domains: negative affect, treatment carryover, and disclosure carryover. Regression models demonstrated convergence with several covariates and demonstrated divergence as expected. CONCLUSION: This study supports the reliability and validity of a short stigma questionnaire in this population. Future studies should continue to assess the validity of this stigma instrument in this population.

Prioritizing Health-Sector Interventions for Noncommunicable Diseases and Injuries in Low- and Lower-Middle Income Countries: National NCDI Poverty Commissions.

Health sector priorities and interventions to prevent and manage noncommunicable diseases and injuries (NCDIs) in low- and lower-middle-income countries (LLMICs) have primarily adopted elements of the World Health Organization Global Action Plan for NCDs 2013-2020. However, there have been limited efforts in LLMICs to prioritize among conditions and health-sector interventions for NCDIs based on local epidemiology and contextually relevant risk factors or that incorporate the equitable distribution of health outcomes. The Lancet Commission on Reframing Noncommunicable Diseases and Injuries for the Poorest Billion supported national NCDI Poverty Commissions to define local NCDI epidemiology, determine an expanded set of priority NCDI conditions, and recommend cost-effective, equitable health-sector interventions. Fifteen national commissions and 1 state-level commission were established from 2016-2019. Six commissions completed the prioritization exercise and selected an average of 25 NCDI conditions; 15 conditions were selected by all commissions, including asthma, breast cancer, cervical cancer, diabetes mellitus type 1 and 2, epilepsy, hypertensive heart disease, intracerebral hemorrhage, ischemic heart disease, ischemic stroke, major depressive disorder, motor vehicle road injuries, rheumatic heart disease, sickle cell disorders, and subarachnoid hemorrhage. The commissions prioritized an average of 35 health-sector interventions based on cost-effectiveness, financial risk protection, and equity-enhancing rankings. The prioritized interventions were estimated to cost an additional US$4.70-US$13.70 per capita or approximately 9.7%-35.6% of current total health expenditure (0.6%-4.0% of current gross domestic product). Semistructured surveys and qualitative interviews of commission representatives demonstrated positive outcomes in several thematic areas, including understanding NCDIs of poverty, informing national planning and implementation of NCDI health-sector interventions, and improving governance and coordination for NCDIs. Overall, national NCDI Poverty Commissions provided a platform for evidence-based, locally driven determination of priorities within NCDIs.

Facilitators, barriers and potential solutions to the integration of depression and non-communicable diseases (NCDs) care in Malawi: a qualitative study with service providers.

BACKGROUND: Integration of depression services into infectious disease care is feasible, acceptable, and effective in sub-Saharan African settings. However, while the region shifts focus to include chronic diseases, additional information is required to integrate depression services into chronic disease settings. We assessed service providers' views on the concept of integrating depression care into non-communicable diseases' (NCD) clinics in Malawi. The aim of this analysis was to better understand barriers, facilitators, and solutions to integrating depression into NCD services. METHODS: Between June and August 2018, we conducted nineteen in-depth interviews with providers. Providers were recruited from 10 public hospitals located within the central region of Malawi (i.e., 2 per clinic, with the exception of one clinic where only one provider was interviewed because of scheduling challenges). Using a semi structured interview guide, we asked participants questions related to their understanding of depression and its management at their clinic. We used thematic analysis allowing for both inductive and deductive approach. Themes that emerged related to facilitators, barriers and suggested solutions to integrate depression assessment and care into NCD clinics. We used CFIR constructs to categorize the facilitators and barriers. RESULTS: Almost all providers knew what depression is and its associated signs and symptoms. Almost all facilities had an NCD-dedicated room and reported that integrating depression into NCD care was feasible. Facilitators of service integration included readiness to integrate services by the NCD providers, availability of antidepressants at the clinic. Barriers to service integration included limited knowledge and lack of training regarding depression care, inadequacy of both human and material resources, high workload experienced by the providers and lack of physical space for some depression services especially counseling. Suggested solutions were training of NCD staff on depression assessment and care, engaging hospital leaders to create an NCD and depression care integration policy, integrating depression information into existing documents, increasing staff, and reorganizing clinic flow. CONCLUSION: Findings of this study suggest a need for innovative implementation science solutions such as reorganizing clinic flow to increase the quality and duration of the patient-provider interaction, as well as ongoing trainings and supervisions to increase clinical knowledge.

Identifying challenges and recommendations for advancing global mental health implementation research: A key informant study of the National Institute of Mental Health Scale-Up Hubs.

OBJECTIVE: This study explored perspectives of researchers working with the National Institute of Mental Health (NIMH) Scale-Up Hubs, consisting of research partnerships for scaling up mental health interventions in low- and middle-income countries (LMICs), to: 1) identify common barriers to conducting impactful research on the implementation of evidence-based mental health services; and 2) provide recommendations to overcome these implementation challenges. METHODS: A sequential qualitative approach was employed. First, an open-ended survey was distributed to the 10 Scale-Up Hubs and NIMH program staff asking informants to identify challenges in conducting mental health implementation research in LMICs. Second, survey findings guided an in-person workshop to generate implementation recommendations to inform the field. RESULTS: In total, 46 respondents completed surveys, and 101 researchers attended the workshop. The workshop produced implementation recommendations for low-resource settings: 1) identifying impact of research on policy and practice; 2) sustaining careers of early researchers in global mental health; 3) engaging policymakers and donors to value mental health research; 4) supporting the workforce for delivering evidence-based treatments for mental disorders; and 5) promoting sustainability of programs. CONCLUSIONS: These findings can strengthen collaboration between researchers and key stakeholders, and highlight important targets for improving mental health implementation research in LMICs.

The Sub-Saharan Africa Regional Partnership (SHARP) for Mental Health Capacity-Building Scale-Up Trial: Study Design and Protocol.

BACKGROUND: Depression is a leading cause of death and disability worldwide, including in low- and middle-income countries (LMICs). Depression often coexists with chronic medical conditions and is associated with worse clinical outcomes. This confluence has led to calls to integrate mental health treatment with chronic disease care systems in LMICs. This article describes the rationale and protocol for a trial comparing the clinical effectiveness and cost-effectiveness of two different intervention packages to implement evidence-based antidepressant management and psychotherapy into chronic noncommunicable disease (NCD) clinics in Malawi. METHODS: Using constrained randomization, the Sub-Saharan Africa Regional Partnership (SHARP) for mental health capacity building will assign five Malawian NCD clinics to a basic implementation strategy via an internal coordinator, a provider within the chronic care clinic who champions depression services by providing training, supervision, operations, and reporting. Another five clinics will be assigned to depression services implementation via an internal coordinator along with an external quality assurance committee, which will provide a quarterly audit of intervention component delivery with feedback to providers and the health management team. RESULTS: The authors will compare key implementation outcomes (fidelity to intervention), clinical effectiveness outcomes (patient health), and cost-effectiveness and will assess characteristics of clinics that may influence uptake and fidelity. NEXT STEPS: This trial will provide key information to guide the Malawi Ministry of Health in scaling up depression management in existing NCD settings. The SHARP trial is anticipated to substantially contribute to enhancing both mental health treatment and implementation science research capacity in Malawi and the wider region.

Availability of equipment and medications for non-communicable diseases and injuries at public first-referral level hospitals: a cross-sectional analysis of service provision assessments in eight low-income countries.

CONTEXT AND OBJECTIVES: Non-communicable diseases and injuries (NCDIs) comprise a large share of mortality and morbidity in low-income countries (LICs), many of which occur earlier in life and with greater severity than in higher income settings. Our objective was to assess availability of essential equipment and medications required for a broad range of acute and chronic NCDI conditions. DESIGN: Secondary analysis of existing cross-sectional survey data. SETTING: We used data from Service Provision Assessment surveys in Bangladesh, the Democratic Republic of the Congo, Ethiopia, Haiti, Malawi, Nepal, Senegal and Tanzania, focusing on public first-referral level hospitals in each country. OUTCOME MEASURES: We defined sets of equipment and medications required for diagnosis and management of four acute and nine chronic NCDI conditions and determined availability of these items at the health facilities. RESULTS: Overall, 797 hospitals were included. Medication and equipment availability was highest for acute epilepsy (country estimates ranging from 40% to 95%) and stage 1-2 hypertension (28%-83%). Availability was low for type 1 diabetes (1%-70%), type 2 diabetes (3%-57%), asthma (0%-7%) and acute presentations of diabetes (0%-26%) and asthma (0%-4%). Few hospitals had equipment or medications for heart failure (0%-32%), rheumatic heart disease (0%-23%), hypertensive emergencies (0%-64%) or acute minor surgical conditions (0%-5%). Data for chronic pain were limited to only two countries. Availability of essential medications and equipment was lower than previous facility-reported service availability. CONCLUSIONS: Our findings demonstrate low availability of essential equipment and medications for diverse NCDIs at first-referral level hospitals in eight LICs. There is a need for decentralisation and integration of NCDI services in existing care platforms and improved assessment and monitoring to fully achieve universal health coverage.

May Measurement Month 2018: an analysis of blood pressure screening results from Malawi.

Raised blood pressure (BP) is a growing health care problem in the world leading to over 10 million deaths annually. May Measurement Month (MMM), which aims at raising awareness and screening people for raised BP, is assisting people to know their BP status. In 2018, an opportunistic cross-sectional survey was carried out during May and June in 10 791 volunteers aged 18 years and above following that done in 2017. The screening took place in Lilongwe, Blantyre, Dedza, Kasungu, and Nkhatabay districts mostly in hospitals/clinics, marketplaces, workplaces, and churches/mosques with Kasungu and Nkhatabay in rural areas. After multiple imputation, 2404 (22.3%) had hypertension. Of individuals not receiving antihypertensive treatment, 2101 (20.0%) were found to have raised BP. Only 303 (12.6%) of those with hypertension were receiving antihypertensive treatment, and of these 101 (33.3%) had uncontrolled BP. MMM was the largest BP screening campaign ever undertaken in Malawi. The results identified a large number of individuals with raised BP who were unaware and not on treatment and over one-third of those on treatment were uncontrolled, indicating the need for better management of cases. These results suggest that opportunistic screening can identify significant numbers with raised BP.

The role of patient-provider communication: a qualitative study of patient attitudes regarding co-occurring depression and chronic diseases in Malawi.

BACKGROUND: Globally, depression is a leading cause of morbidity and mortality particularly in Low and Middle-Income Countries (LMICs). The burden of non-communicable diseases (NCDs) are also increasing in LMICs, the conditions frequently co-occur and exacerbate NCD outcomes. Depression interventions alone are not effective at improving NCD outcomes, resulting in wide-reaching calls for integrated services. Integrated services are in a nascent phase in LMICs in general and in Malawi in particular. This manuscript serves to clarify Malawian patients' attitudes and perceptions towards depression integration into routine NCD services. METHODS: Ten District Hospitals were selected for data collection and 2 participants were interviewed from each site (N = 20). An iterative approach to concept-driven coding was applied to facilitate the formation of similarities, differences, and connections between codes. RESULTS: While patients infrequently described moderate depression as a medical condition, and held various attitudes regarding treatments, they agreed on the appropriateness of integrated services. Patients' respect for their providers led them to support integration. Patients discussed how medical knowledge is highly regarded, revealing a power dynamic with their providers. Patients further acknowledged the importance of a provider's communication in shaping a patient's feelings about depression. CONCLUSIONS: Training and interventions that facilitate providers' abilities to transfer their medical knowledge, use strategies to channel their power, and engage patients in a meaningful and collaborative relationship will be key to successfully integrating depression treatment into Malawian NCD clinics. TRIAL REGISTRATION: This work served as part of formative data collection for National Institute of Mental Health (NIMH) Trail NCT03711786 registered on 10th October, 2018.

Non-communicable respiratory disease in Malawi: a systematic review and meta-analysis.

BACKGROUND: Non-communicable respiratory diseases are important contributors to morbidity and mortality in sub-Saharan African countries such as Malawi. AIM: To conduct a systematic review of the available literature relating to chronic respiratory disease in Malawi. METHODS: We conducted a systematic protocol-driven literature search of key scientific databases including Scopus and Medline. Papers were independently assessed for eligibility by two authors and included if they reported objective measures (including self-reported standard symptoms) of chronic respiratory disease and were conducted in Malawi. A meta-analysis of available estimates was then conducted. We re-analysed data from three of these studies in a secondary data analysis to allow for between-study comparisons. RESULTS: Our search identified 393 papers of which 17 (5 involving children and 12 involving adults) met the inclusion criteria. Wheeze was the symptom most frequently reported in children in the community (12.1%), hospital (11.2%) and HIV clinic (8.1%) settings. Cough was the symptom most frequently reported by adults in the community (3-18%). Spirometric abnormalities varied substantially between studies. For example, in adults, airflow obstruction varied between 2.3% and 20% and low forced vital capacity (FVC) varied between 2.7% and 52.8%. CONCLUSION: We identified a high burden of chronic respiratory symptoms and abnormal spirometry (particularly low FVC) within paediatric and adult populations in Malawi. The estimates for country-wide burden related to this disease were limited by the heterogeneity of the methods used to assess symptoms and spirometry. There is an urgent need to develop a better understanding of the determinants and natural history of non-communicable respiratory disease across the life-course in Malawi.

Systematic Review of Hypertension and Diabetes Burden, Risk Factors, and Interventions for Prevention and Control in Malawi: The NCD BRITE Consortium.

Recent studies have found an increasing burden of noncommunicable diseases in sub-Saharan Africa. A compressive search of PubMed, Medline, EMBASE, and the World Health Organization Global Health Library databases was undertaken to identify studies reporting on the prevalence, risk factors, and interventions for hypertension and diabetes in Malawi. The findings from 23 included studies revealed a high burden of hypertension and diabetes in Malawi, with estimates ranging from 15.8% to 32.9% and from 2.4% to 5.6%, respectively. Associated risk factors included old age, tobacco smoking, excessive alcohol consumption, obesity, physical inactivity, high salt and sugar intake, low fruit and vegetable intake, high body mass index, and high waist-to-hip ratio. Certain antiretroviral therapy regimens were also associated with increased diabetes and hypertension risk in human immunodeficiency virus patient populations. Nationwide, the quality of clinical care was generally limited and demonstrated a need for innovative and targeted interventions to prevent, control, and treat noncommunicable diseases in Malawi.

The Malawi NCD BRITE Consortium: Building Research Capacity, Implementation, and Translation Expertise for Noncommunicable Diseases.

Africa is experiencing an increasing prevalence of noncommunicable diseases (NCD). However, few reliable data are available on their true burden, main risk factors, and economic impact that are needed to inform implementation of evidence-based interventions in the local context. In Malawi, a number of initiatives have begun addressing the NCD challenge, which have often utilized existing infectious disease infrastructure. It will be crucial to carefully leverage these synergies to maximize their impact. NCD-BRITE (Building Research Capacity, Implementation, and Translation Expertise) is a transdisciplinary consortium that brings together key research institutions, the Ministry of Health, and other stakeholders to build long-term, sustainable, NCD-focused implementation research capacity. Led by University of Malawi-College of Medicine, University of North Carolina, and Dignitas International, NCD-BRITE's specific aims are to conduct detailed assessments of the burden and risk factors of common NCD; assess the research infrastructure needed to inform, implement, and evaluate NCD interventions; create a national implementation research agenda for priority NCD; and develop NCD-focused implementation research capacity through short courses, mentored research awards, and an internship placement program. The capacity-building activities are purposely designed around the University of Malawi-College of Medicine and Ministry of Health to ensure sustainability. The NCD BRITE Consortium was launched in February 2018. In year 1, we have developed NCD-focused implementation research capacity. Needs assessments will follow in years 2 and 3. Finally, in year 4, the generated research capacity, together with findings from the needs assessments, will be used to create a national, actionable, implementation research agenda for NCD prioritized in this consortium, namely cardiovascular disease, diabetes mellitus, and asthma and chronic obstructive pulmonary disease.

May Measurement Month 2017: results of a blood pressure screening campaign in Malawi-Sub-Saharan Africa.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. May Measurement Month (MMM) is a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programs worldwide. A World Health Organization and Ministry of Health STEPS Survey conducted in 2009 in Malawi found that 32.9% tested positive for age-standardized hypertension. The survey further showed that three-quarters (75%) of the participants never had their BP measured before and 94.9% with high BP were unaware of the hypertensive condition. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. BP measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. The screening took place in cities of Lilongwe and Blantyre mostly in hospitals, clinics, marketplaces, workplaces, and churches. About 4009 individuals were screened during MMM17. After multiple imputations, 849 (22.3%) had hypertension. Of individuals not receiving antihypertensive medication, 697 (19.1%) were found to have hypertension. Only 152 individuals were receiving antihypertensive medication, and of these 78 (51.4%) had uncontrolled BP. MMM17 was the largest BP screening campaign ever undertaken in Malawi. The results identified a large number with hypertension who were not on treatment and over half of those on antihypertensive treatment who were uncontrolled, indicating the need for better management of cases. These results suggest that opportunistic screening can identify significant numbers with raised BP.
