Feasibility and acceptability of a community health worker administered behavioral activation intervention for postpartum depression: a single arm pilot study from India.

Women in India experience high rates of postpartum depression (PPD), with minimal availability of screening or treatment. India has an extensive network of community health workers, known as accredited social health activists (ASHAs). While they are knowledgeable about most maternal-child health problems, they have minimal knowledge about PPD. We trained ASHAs to deliver a simple home-based intervention, behavioral activation (BA), which involves individuals in activities that are sources of positive reinforcement to counter depression. The research questions guiding this study were as follows: 1) What are the feasibility and acceptability of ASHAs screening for and delivering a brief behavioral activation intervention addressing PPD among women in Belagavi, South India? 2) What impact did the brief behavioral activation intervention have on PPD? The mixed methods evaluation used interviews with participants and interventionists, and depression scores were assessed before and after the evaluation. After a 2-day training with 17 ASHAs that focused on understanding PPD, screening using the Edinburgh Postnatal Depression Scale (EPDS), and implementing the BA protocol, ASHAs and researcher supervisors screened the mothers 6-12 weeks postpartum presenting at pediatric immunization clinics. Mothers who screened positive were invited to participate in an ASHA-led 5-week BA intervention, with ASHAs visiting the mothers' homes. We assessed post-intervention EPDS scores and conducted satisfaction assessments and individual interviews. All 26 women who screened positive on the EPDS agreed to be enrolled in the study. All participants had a significant reduction (p < 0.001) in PPD scores. Both ASHAs and mothers had high enthusiasm for the intervention methods and activities. This ASHA-delivered BA intervention was found to be feasible, acceptable, and effective in treating PPD in rural Indian mothers. This corroborates literature that demonstrates the efficacy of a BA intervention among individuals with generalized depression in South Asia. In communities with minimal mental health resources, interventions led by trained community workers have the potential to address PPD.

Malaria surveillance and case management in remote and indigenous communities of Panama: results from a community-based health worker pilot

BackgroundPanama is one of eight countries in Mesoamerica that aims to eliminate malaria by 2022. Malaria is concentrated in indigenous and remote regions like Guna Yala, a politically autonomous region where access to health services is limited and cases are predominately detected through intermittent active surveillance. To improve routine access to care, a joint effort was made by Guna Yala authorities and the Ministry of Health to pilot a network of community health workers (CHWs) equipped with rapid diagnostic tests and treatment. The impact of this pilot is described.MethodsAccess to care was measured using the proportion of villages targeted by the effort with active CHWs. Epidemiological impact was evaluated through standard surveillance and case management measures. Tests for differences in proportions or rates were used to compare measures prior to (October 2014-September 2016) and during the pilot (October 2016-September 2018).ResultsAn active CHW was placed in 39 (95%) of 41 target communities. During the pilot, CHWs detected 61% of all reported cases from the region. Test positivity in the population tested by CHWs (22%) was higher than in those tested through active surveillance, both before (3.8%) and during the pilot (2.9%). From the pre-pilot to the pilot period, annual blood examination rates decreased (9.8 per 100 vs. 8.0 per 100), test positivity increased (4.2% to 8.5%, Χ2 = 126.3, p < 0.001) and reported incidence increased (4.1 cases per 1000 to 6.9 cases per 1000 [Incidence Rate Ratio = 1.83, 95% CI 1.52, 2.21]). The percent of cases tested on the day of symptom onset increased from 8 to 27% and those treated on the day of their test increased from 26 to 84%.ConclusionsThe CHW network allowed for replacement of routine active surveillance with strong passive case detection leading to more targeted and timely testing and treatment. The higher test positivity among those tested by CHWs compared to active surveillance suggests that they detected cases in a high-risk population that had not previously benefited from access to diagnosis and treatment. Surveillance data acquired through this CHW network can be used to better target active case detection to populations at highest risk.

Feasibility of establishing a network of community health workers to support care of people with sickle cell disease in Kumasi, Ghana.

Globally, sickle cell disease (SCD) is a common, yet often neglected, non-communicable disease. Community health worker (CHW) interventions have been shown to improve outcomes for chronic diseases but have not been evaluated with SCD. This study assessed the interest in and feasibility of establishing a network of CHWs to support care of people with SCD in Kumasi, Ghana. Using in-depth interviews with key stakeholders (N = 15) identified through purposive and snowball sampling from January to March 2020, we gathered focused information about interest in and feasibility of establishing a network of CHWs. Respondents were chosen for their knowledge and oversight of health services for people with SCD. Latent content analysis was used to examine the data. Participants expressed interest in establishing a network of CHWs to better support care for people with SCD. Three primary themes emerged from the data: (1) support by CHWs could be beneficial for people with SCD; (2) using existing CHW networks for SCD services would be best; and (3) funding of expanded CHW network might be a problem. We advocate for the mobilization of resources to expand the current network of CHWs to include a focus on SCD in Kumasi, Ghana. Participants believe that it is feasible to use CHWs to improve care outcomes of people with SCD. There is potential for findings from this exploratory project to be adapted and implemented in other settings throughout sub-Saharan Africa, as well as areas of higher income countries where there are higher proportions of people living with sickle cell.

Optimizing Active Tuberculosis Case Finding: Evaluating the Impact of Community Referral for Chest X-ray Screening and Xpert Testing on Case Notifications in Two Cities in Viet Nam.

To accelerate the reduction in tuberculosis (TB) incidence, it is necessary to optimize the use of innovative tools and approaches available within a local context. This study evaluated the use of an existing network of community health workers (CHW) for active case finding, in combination with mobile chest X-ray (CXR) screening events and the expansion of Xpert MTB/RIF testing eligibility, in order to reach people with TB who had been missed by the current system. A controlled intervention study was conducted from January 2018 to March 2019 in five intervention and four control districts of two low to medium TB burden cities in Viet Nam. CHWs screened and referred eligible persons for CXR to TB care facilities or mobile screening events in the community. The initial diagnostic test was Xpert MTB/RIF for persons with parenchymal abnormalities suggestive of TB on CXR or otherwise on smear microscopy. We analyzed the TB care cascade by calculating the yield and number needed to screen (NNS), estimated the impact on TB notifications and conducted a pre-/postintervention comparison of TB notification rates using controlled, interrupted time series (ITS) analyses. We screened 30,336 individuals in both cities to detect and treat 243 individuals with TB, 88.9% of whom completed treatment successfully. All forms of TB notifications rose by +18.3% (95% CI: +15.8%, +20.8%). The ITS detected a significant postintervention step-increase in the intervention area for all-form TB notification rates (IRR(β6) = 1.221 (95% CI: 1.011, 1.475); p = 0.038). The combined use of CHWs for active case findings and mobile CXR screening expanded the access to and uptake of Xpert MTB/RIF testing and resulted in a significant increase in TB notifications. This model could serve as a blueprint for expansion throughout Vietnam. Moreover, the results demonstrate the need to optimize the use of the best available tools and approaches in order to end TB.

Navigating the COVID-19 Pandemic: Lessons From Global Surgery.

Many hospitals in HIC rely on just-in-time inventory management, which can be an effective method to cut down on costs, as it calls for minimal reserves of healthcare supplies However, the widespread use of such strategies, which are reliant on consistent and tightly controlled supply chains, have made HIC vulnerable to PPE and supply shortages should demand sharply increase, as has been seen with the COVID-19 pandemic In some HIC hospitals, healthcare workers facing PPE shortages have already had to adopt common practices from LMIC, such as using bin liners instead of gowns and wearing reusable cloth masks HIC providers have also implemented evidence based adaptations, such as creating reusable elastomeric respirators, the development of open source ventilators, and reprocessing N95 masks using the hydrogen peroxide vapor sterilization technique Learning how LMIC providers manage resource limitations through global surgery collaborations can give surgeons working in HIC valuable perspective that has become increasingly relevant during the COVID-19 pandemic The rapid expansion of social media has facilitated such collaborations, and is a valuable tool for networking, mentorship, and information sharing Additionally, the rapid sharing of research findings via social media is enhancing our ability as a global health community to respond to this pandemic in a strong evidence based manner However, it is essential that social media be used responsibly, and that precautions are taken to prevent the spread of misinformation The most vulnerable populations, often linked to the underlying social determinants of health such as poverty, food security, literacy, sex, and racial and ethnic factors, are most at risk of adverse outcomes during these health and social shocks There is already data demonstrating that racial and ethnic minorities in the US and UK are at increased risk of death from COVID-19 Difficulty in accessing care for emergent conditions exists at baseline for these populations, and extensive backlogs for essential operations are commonplace, especially in LMIC This is likely only to get worse during the current crisis and underscores the importance of our professional commitment to health equity - regardless of geography New estimates of the "collateral damage" caused by the pandemic are very concerning and also illustrate the urgent need to mitigate this impact through local and global coordinated action

Home delivery of medication during Coronavirus disease 2019, Cape Town, South Africa: Short report

The public sector primary care facilities in Cape Town serve a large number of patients with chronic diseases such as human immunodeficiency virus, tuberculosis, diabetes, hypertension, asthma and chronic obstructive pulmonary disease. Prior to the Coronavirus disease 2019 (COVID-19) epidemic, stable patients with chronic conditions attended the facility or support groups to obtain their medication. During the COVID-19 epidemic, these patients would be put at risk if they had to travel and gather in groups to receive medication. The Metropolitan Health Services, therefore, decided to offer home delivery of medication. A system of home delivery was rapidly established by linking the existing chronic dispensing unit system with the emerging approach to community-orientated primary care in the Metro. Medication was delivered as usual to primary care pharmacies, but then a variety of means were used to disseminate the parcels to local non-profit organisations, where they could be delivered by a city-wide network of community health workers (CHWs). Innovations included various ways of delivering the parcels, including via Uber, bicycles and electric scooters, as well as Google forms to monitor the success of the initiative. It was estimated that up to 200 000 parcels per month could be delivered in this way via 2500 CHWs. The new system was established throughout the Metropole, and its strengths, weaknesses, opportunities and threats are further discussed. The initiative may prevent COVID-19 amongst people with comorbidities who would be at risk of more severe diseases. It may also have de-congested primary care facilities ahead of the expected surge in COVID-19 cases.

High level of treatment failure and drug resistance to first-line antiretroviral therapies among HIV-infected children receiving decentralized care in Senegal

BackgroundIn Senegal in 2015, an estimated 4800 children were living with HIV, with 1200 receiving ARV treatment, of whom half had follow-up care in decentralized sites outside Dakar.However, until now no studies have determined the efficacy of pediatric treatment in decentralized settings, even though the emergence of viral resistance, particularly among children in Africa, is a well-known phenomenon. This study aimed to assess the virological status of HIV-infected children in all decentralized facilities to help improve access to quality care.MethodsA cross-sectional epidemiological and virological study was conducted in all of Senegal’s regions, except Dakar, between March and June 2015 and sought to include all HIV-infected children and adolescents (0–19 years), treated or not with ARVs.Socio-demographic and clinical data and a blood sample on blotting paper were collected for children from treatment sites. Samples were routed on public transportation, assisted by a network of community health workers. A viral load (VL) assay was performed for each child, followed by genotyping when it exceeded 1000 copies/mL (3 log10).ResultsOf the 851 identified children, 666 (78%) were enrolled in the study. Half of the children were girls, and the average age was 8 years (6 months–19 years). Most of the children (96.7%) were infected with HIV-1, and 90% were treated with ART, primarily with AZT + 3TC + NVP/EFV therapeutic regimen. The median duration of time on ART was 21 months (1–129). VL was measured for 2% of children before this study. Almost two-thirds (64%) of the children are experiencing virological failure. Among them, there was resistance to at least one drug for 86.5% of cases. Also, 25% children presented resistance to one drug and 40% to two out of three. For nearly one-third of the children presenting resistance, none of the three drugs of the treatment was active. Factors associated with virological failure were male sex, follow-up by a generalist rather than a specialist, and treatment interruptions.ConclusionsWe observed a high level of virological failure and a high percentage of viral resistance among children receiving health care in decentralized facilities in Senegal.

Malaria case management by community health workers in the Central African Republic from 2009\u20132014: overcoming challenges of access and instability due to conflict

BackgroundIn the Central African Republic (CAR), decades of armed conflict have crippled the public health system. This has left the population without timely access to life-saving services and therefore vulnerable to the numerous consequences of infectious diseases, including malaria. As a response, in 2008 an international non-governmental organization started a network of community health workers (CHWs) in the highly malaria-endemic region of northwest CAR. The area has experienced years of violent clashes between rebel groups and seen hundreds of thousands of people displaced.MethodsData from routine patient registers from 80 CHWs working in Paoua and Markounda sub-prefectures were entered and retrospectively reviewed. The time period covered December 2009–April 2014 and hence different stages of conflict and unrest. Several indicators were measured over time, including malaria rapid diagnostic test (RDT) positivity rates, CHW reporting rates, and malnutrition indicators.ResultsAmong nearly 200,000 people who consulted a CHW during this period, 81% were found to be positive for malaria parasites by RDT. In total, 98.9% of these positive cases were appropriately treated with artemisinin-based combination therapy (ACT). Only 1.2% of RDT negative cases were incorrectly treated with an ACT. Monthly data from each CHW were regularly reported, with more than 96% of CHWs reporting each month in the first 3 years of the project. However, since the coup d’état in March 2013, the number of CHWs reporting each month decreased as the programme battled the additional constraints of civil war.ConclusionsAlthough the political crisis affected the CHWs, the programme showed that it could reach those most vulnerable and continue some level of care at all times. In addition, this programme revealed that surveillance could be maintained in conflict zones. This paper fills a significant gap in the knowledge of malaria control in CAR and this is especially important for agencies which must often decide in a short space of time how to respond effectively to complex emergencies.

Community Health Workers and Disasters: Lessons Learned from the 2015 Earthquake in Nepal

In March 2016, key-informant interviews, FCHV interviews, and focus group discussions (FGDs) were conducted in Nepali health facilities using semi-structured guides. The audio-recorded data were obtained with the assistance of a translator (Nepali-English), transcribed verbatim in English, and coded by two independent researchers (manually and with NVivo 11 Pro software [QSR International; Melbourne, Australia]). Across seven different regions, 14 interviews with FCHVs, two FGDs with community women, and three key-informant interviews were conducted. Four major themes emerged around the topic of FCHVs and the 2015 earthquake: (1) community care and rapport between FCHVs and local residents; (2) emergency response of FCHVs in the immediate aftermath of the earthquake; (3) training requested to improve the FCHVs' ability to manage disasters; and (4) interaction with relief organizations and how to create collaborations that provide aid relief more effectively. The FCHVs in Nepal provided multiple services to their communities in the aftermath of the earthquake, largely without any specific training or instruction. Proper preparation, in addition to improved collaboration with aid agencies, could increase the capacity of FCHVs to respond in the event of a future disaster. The information gained from this study of the FCHV experience in the Nepal earthquake could be used to inform risk reduction and emergency management policies for CHWs in various settings worldwide.

Developing a Network of Community Health Workers: Improving the Lives of Migrant Farmworkers

One of the main strengths of today’s global food system is the labor force. Within emergent countries, farmworkers are an important element of competitiveness. However, food production that frequently stands in developed countries family tables rests upon the usually precarious living and health conditions of farmworkers, especially those that should migrate from regions that are far from the agribusiness where they work and live most of the year. Furthermore, healthcare becomes a challenging task because of cultural, socioeconomic and ethnic barriers. The aim of this study was to develop and evaluate a Community Health Worker (CHW) training model among agricultural Mexican migrant farmworkers, focusing on strengthening a health prevention environment conducive to improve health. This was a qualitative action-driven research carried out in southern Mexico communities as well as at northwest Mexico agribusiness. The project was implemented in four stages: needs assessment, curriculum design, training and implementation and process evaluation. The socioecological model guided our methodological and analytical process; we followed a Community Based Participatory Approach (CBPA) to interview and train a network of 40 CHW. Results showed that CHW’s main health priorities were dehydration and heat stroke, respiratory infections, gastrointestinal infections, work accidents, hygiene, nutrition, as well as mental health including substance abuse and depression. Training evaluation 1) improved communication between middle management and migrant farmworkers, as well as between middle management and farm administrators, 2) increased middle management consciousness about farmworkers health needs and responsibility, and 3) increased awareness about how improving the environment could help prevent diseases.

Health and economic benefits of scaling up a home-based neonatal care package in rural India: a modelling analysis.

Approximately 900 000 newborn children die every year in India, accounting for 28% of neonatal deaths globally. In 2011, India introduced a home-based newborn care (HBNC) package to be delivered by community health workers across rural areas. We estimate the disease and economic burden that could be averted by scaling up the HBNC in rural India using IndiaSim, an agent-based simulation model, to examine two interventions. In the first intervention, the existing community health worker network begins providing HBNC for rural households without access to home- or facility-based newborn care, as introduced by India's recent programme. In the second intervention, we consider increased coverage of HBNC across India so that total coverage of neonatal care (HBNC or otherwise) in the rural areas of each state reaches at least 90%. We find that compared with a baseline of no coverage, providing the care package through the existing network of community health workers could avert 48 [95% uncertainty range (UR) 34-63] incident cases of severe neonatal morbidity and 5 (95% UR 4-7) related deaths, save $4411 (95% UR $3088-$5735) in out-of-pocket treatment costs, and provide $285 (95% UR $200-$371) in value of insurance per 1000 live births in rural India. Increasing the coverage of HBNC to 90% will avert an additional 9 (95% UR 7-12) incident cases, 1 death (95% UR 0.72-1.33), and $613 (95% UR $430-$797) in out-of-pocket expenditures, and provide $55 (95% UR $39-$72) in incremental value of insurance per 1000 live births. Intervention benefits are greater for lower socioeconomic groups and in the poorer states of Chhattisgarh, Uttarakhand, Bihar, Assam and Uttar Pradesh.

Ageing and mental health in a developing country: who cares? Qualitative studies from Goa, India.

While there is a growing body of epidemiological evidence on the prevalence of mental illnesses in late-life in developing countries, there is limited data on cultural perceptions of mental illnesses and care arrangement for older people. This qualitative study used focus group discussions with older people and key informants to investigate the status of older people and concepts of late-life mental health conditions, particularly dementia and depression, in Goa, India. Vignettes of depression and dementia were widely recognized. However, neither condition was thought to constitute a health condition. Dementia was construed as a normal part of ageing and was not perceived as requiring medical care. Thus, primary health physicians rarely saw this condition in their clinical work, but community health workers frequently recognized individuals with dementia. Depression was a common presentation in primary care, but infrequently diagnosed. Both late-life mental disorders were attributed to abuse, neglect, or lack of love on the part of children towards a parent. There was evidence that the system of family care and support for older persons was less reliable than has been claimed. Care was often conditional upon the child's expectation of inheriting the parent's property. Care for those with dependency needs was almost entirely family-based with little or no formal services. Unsurprisingly, fear for the future, and in particular 'dependency anxiety' was commonplace among older Goans. There is a need to raise awareness about mental disorders in late-life in the community and among health professionals, and to improve access to appropriate health care for the elderly with mental illness. The study suggests directions for the future development of locally appropriate support services, such as involving the comprehensive network of community health workers.

Strengthening health services for MCH in Africa: the first four years of the ‘Bamako Initiative’

The basic intent of the Bamako Initiative which is supported by African Ministers of Health WHO and UNICEF was to provide longterm sustainability of primary health care (PHC) by strengthening community mobilization and using community resources and strengthening district level health services. National government would focus on the referral system. Consideration in this article is given to important issues that have arisen since its inception in 1987 the policy framework key components the global action country progress (Benin Guinea Kenya Nigeria Sierra Leone Togo Mali and Zaire) key management questions and future directions in the next decade. The Bamako Initiative has 4 key features: 1) the rehabilitation and extension of the basic health care delivery system particularly for maternal and child health services and including peripheral health facilities and the network of community health workers; 2) provision for affordable drugs and improved knowledge on prescribing and use; 3) appropriate financing of services for longterm sustainability; and 4) community mobilization in order to increase the effectiveness and esteem of health services and involving the community as a full partner in the decision making process. The Ministers agreed to 8 principles which would facilitate the implementation of the Bamako Initiative in September 1988 as follows: 1) national commitment to the development of universally accessible PHC services 2) essential drug policies in agreement with the development of PHC 3) community financing which is consistent at all levels of care for health care services 4) substantial government financial support 5) substantial decentralization to the district level for management of PHC 6) decentralized management of community resources 7) measures which ensure access of the poor for PHC and 8) clearly defined intermediate objectives and agreement on indicators to evaluate the effectiveness. A number of issues have arisen concerning the implementation of the Initiative such as community control equity drug use and the low status of health workers. Since 1988 UNICEF has established funding for national task forces and conducted 3 conferences to deal with the issues and constraints. Collaboration is important and considerable involvement has been effected by the World Bank the African Development Bank and multilateral bilateral and government agencies. The most active supporter of the Initiative has been Nigeria. Key lessons are that there is a need for policy development for support from national and local leaders for a supportive legal system for detailed planning for logistics strategies and workable management for information management for operations research and for balanced implementation in rural and urban areas. International solidarity is need to provide the resources to fulfill the aims.
