Impact of community health workers on improving identification and primary care of hypertension among the urban poor - findings from Chhattisgarh state of India.

BACKGROUND: Hypertension is a major health problem globally and in India. Around 60% of people with hypertension in India are not aware that they have the condition. Less than 30% of individuals with hypertension are on treatment. Existing studies have indicated that community health workers (CHWs) can play a useful role in expanding the care for hypertension. Evaluations are needed to study the impact when an intervention is implemented by the government in its existing large-scale CHW programme to improve the identification, regular follow-up and medication adherence for hypertension. METHODS: Chhattisgarh state implemented a pilot intervention to improve screening and follow-up for hypertension by equipping Mitanin-CHWs to measure blood pressure (BP). The study design involved an intervention-group and a comparison-group of urban slum population. The survey covered 5974 individuals (30-79 years age) in intervention-group and 5131 in comparison-group. Multivariate analysis was conducted to find out the effect of intervention on the desired outcomes. RESULTS: In intervention-group, 80.2% of the individuals (30-79 years age) had been screened for hypertension whereas the proportion was 37.9% in comparison-group. For 47.0% of individuals in intervention-group, Mitanin CHW was the provider who measured BP for the first time. Around 16.3% of individuals in intervention-group and 9.5% in comparison-group had been diagnosed with hypertension. Around 85.9% of hypertension cases in intervention-group and 77.0% in comparison-group were on treatment. BP had been measured in preceding 30 days for 81.8% of hypertension-cases in intervention-group and 64.3% in comparison-group. Around 70.3% of hypertension-cases in intervention-group and 55.1% in comparison-group had taken their complete medication for last seven days. Multivariate analysis showed that CHW intervention was associated significantly with improvements in all the desired outcomes. CONCLUSION: Equipping the CHWs to measure BP was effective in increasing the screening and identification of hypertension, regular measurement of BP of individuals with hypertension and the adherence to medication. This shows the potential if the one-million strong work-force of Accredited-Social-Health-Activists (ASHA) CHWs in India gets equipped for this role. Governments need to provide a stronger policy push to get this materialised.

Assessing afebrile malaria and bed-net use in a high-burden region of India: Findings from multiple rounds of mass screening.

A key obstacle in the fight against malaria is afebrile malaria. It remains undiagnosed and, therefore, is invisible to the health system. Apart from being a serious illness, it contributes to increased transmission. Existing studies in India have not adequately reported afebrile malaria and its determinants, including the use of long-lasting insecticide-treated nets (LLINs). This study used six waves of mass screening, which were conducted by the state government in the high-malaria-burden region of Chhattisgarh, a state in India, in 2020, 2021, and 2022. Each round of data collection included more than 15000 individuals. Descriptive statistics were used to analyse key indicators of malaria prevalence and LLIN use. Multivariate analyses were performed to identify the determinants of afebrile malaria and LLIN use. Malaria prevalence in the afebrile population varied from 0.6% to 1.4% across the different waves of mass screening. In comparison, malaria positivity among febrile individuals was greater than 33% in each wave. Afebrile malaria contributed to 19.6% to 47.2% of the overall malaria burden in the region. Indigenous communities (scheduled tribes) were more susceptible to malaria, including afebrile malaria. Individuals using LLINs were less likely to be affected by afebrile malaria. Overall, 77% of the individuals used LLINs in early monsoon season, and in winter the rate was lower at 55%. LLIN use was significantly associated with the number of LLINs the households received from the government. Although fever continues to be a primary symptom of malaria, afebrile malaria remains a significant contributor to the malaria burden in the region. The free distribution of LLINs should be expanded to include high-burden populations. Global policies must include strategies for surveillance and control of afebrile malaria in high-burden areas.

Role of Mitanin community health workers in improving complementary feeding practices under scaled-up home-based care of young children in a rural region of India.

BACKGROUND: A large proportion of young children in developing countries receive inadequate feeding and face frequent infections. Global research has established the need for improving feeding practices and management of child illnesses. Interventions involving home visits by community health workers (CHWs) for caregiver education have been attempted in many countries. Indian government rolled out an intervention called home-based care of young children (HBYC) in 2018 but no studies exist of its scaled-up implementation. The current study was aimed at assessing the coverage of HBYC in Chhattisgarh state where it has been implemented through 67,000 rural CHWs known as Mitanins. METHODS: This cross-sectional study was based on a primary household survey. Households with children in 7-36 months age were eligible for survey. A multi-stage sample of 2646 households was covered. Descriptive analyses were performed and key indicators were reported with 95% confidence intervals. To find out the association between caregiver practices and receiving advice from the CHWs, multivariate regression models were applied. RESULTS: Overall, 85.1% children in 7-36 months age received at least one home visit from a CHW within the preceding three months. Complementary feeding had been initiated for 67% of children at six months age and the rate was 87% at eight months age. Around one-third of the children were fed less than three times a day. Around 41% households added oil in child's food the preceding day. CHWs were contacted in 73%, 69% and 61% cases of diarrhea, fever and respiratory infections respectively in children. Among those contacting a CHW for diarrhea, 88% received oral rehydration. The adjusted models showed that receiving advice from CHWs was significantly associated with timely initiation of complementary feeding, increasing the frequency of feeding, increasing diet diversity, addition of oil, weighing and consumption of food received from government's supplementary nutrition programme. CONCLUSIONS: Along with improving food security of households, covering a large share of young children population with quality home visits under scaled-up CHW programmes can be the key to achieving improvements in complementary feeding and child care practices in developing countries.

Assessing the time use and payments of multipurpose community health workers for the various roles they play-a quantitative study of the Mitanin programme in India.

BACKGROUND: Community health workers (CHWs) are crucial human resources for health. While specialist CHWs focus on a single disease vertically, the generalist or multipurpose CHWs perform wider functions. The current study was aimed at examining the time multipurpose CHWs spend on performing their different roles. This can help in understanding the importance they attach to each role. Since CHWs in many developing countries are classified as part-time volunteers, this study also aimed to assess the adequacy of CHW payments in relation to their time use. METHODS: The study covered a well-established CHW programme in India's Chhattisgarh state. It had 71,000 multipurpose part-time CHWs known as Mitanins. Data collection involved interviews with a representative sample of 660 rural and 406 urban Mitanins. A semi-structured tool was designed and field tested. It included 26 pre-coded activities of CHWs placed under their six purposes or roles. Prompting and triangulation were used during interviews to mitigate the possibility of over-reporting of work by CHWs. The recall period was of one week. Descriptive analysis included comparison of key indicators for rural and urban Mitanins. A multi-variate linear model was used to find the determinants of CHW time-use. RESULTS: The rural and urban Mitanins respectively spent 25.3 and 34.8 h per week on their CHW work. Apart from location (urban), the total time spent was associated with size of population covered. The time-use was well balanced between roles of service-linkage, providing health education and curative care directly, COVID-19 related work and action on social determinants of health. More than half of their time-use was for unpaid tasks. Most of the cash-incentives were concentrated on service linkage role. The average payment earned by Mitanins was less than 60% of legal minimum wage. CONCLUSION: The time-use pattern of Mitanins was not dictated by cash-incentives and their solidarity with community seemed be a key motivator. To allow wide ranging CHW action like Mitanins, the population per CHW should be decided appropriately. The considerable time multipurpose CHWs spend on their work necessitates that developing countries develop policies to comply with World Health Organisation's recommendation to pay them fairly.

Coverage of home-based newborn care and screening by ASHA community health workers: Findings from a household survey in Chhattisgarh state of India.

Background and Objectives: Community health workers known as Accredited Social Health Activists (ASHAs) provide home visits for home-based newborn care (HBNC) in India. The objectives of the study were to assess coverage of HBNC, to assess current practices of newborn care by the care providers and to assess status of screening of sick newborns by ASHAs in rural Chhattisgarh. Methods: The study was a quantitative cross-sectional study. Multi-stage random sampling was applied to draw a representative sample from rural Chhattisgarh. The survey collected primary data of 1928 newborns by interviewing the caregivers. Descriptive statistical analysis using cross tabulations was performed. Confidence intervals at 95% were computed for key indicators. Results: ASHAs were present during 84.3% of the deliveries. 74.1% newborns received the designated six home visits from ASHAs whereas 3.6% newborns did not receive any visits. Coverage of different important messages ranged from 74% to 90%. Around 95% of newborns were screened by ASHAs for signs of sickness. ASHAs identified 12.9% of newborns as sick. Of the identified sick newborns, 48.1% were referred by ASHAs to health facilities, whereas 34.7% were treated directly by ASHAs by using amoxicillin. Early initiation of breastfeeding was reported for 85.4% of newborns and skin-to-skin contact was practiced for 63.6%. Conclusions: ASHAs were able to achieve an adequate coverage of HBNC in rural Chhattisgarh. Uptake of desired newborn care practices by caregivers was found. Identification of sick newborn was also adequate. Further research is recommended to identify factors facilitating the coverage under HBNC.

Malaria prevalence in symptomatic and asymptomatic pregnant women in a high malaria-burden state in India.

INTRODUCTION: Malaria in pregnancy ('MiP') poses risks to mother, foetus and newborn. Studies from Africa and Asia have reported high prevalence of 'MiP' and recommended further research to address 'MiP'. India has a significant burden of 'MiP' but most of the studies are a decade old. Hardly any studies exist in India that report on asymptomatic malaria in pregnant women. The current Indian policies for malaria control are silent on 'MiP'. A campaign was carried out by community health workers (CHWs) in 2019 to screen pregnant women across rural Chhattisgarh. METHODS: This is a cross-sectional study. Malaria was tested in pregnant women by CHWs using bivalent rapid tests. Multi-stage sampling was used to cover 21,572 pregnant women screened across different geographical areas of rural Chhattisgarh. Cross-tabulation and multivariate regression were used to find out the relationship of 'MiP' with different symptoms and geographical areas. GIS maps were used to compare malaria in pregnant women against overall febrile population. RESULTS: In rural Chhattisgarh, malaria was present in 0.81% of the pregnant women at the time of testing. 'MiP' prevalence varied across geographies, reaching 4.48% in the geographical division with highest burden. Febrile pregnant women had three times greater malaria-positivity than overall febrile population and both showed a similar geographical pattern. DISCUSSION: Prevalence of 'MiP' was found to be less than earlier studies in the state. Though overall malaria in India has shown some decline, a policy response is needed for 'MiP' in high-burden areas. Fever, diarrhoea and jaundice remain relevant symptoms in 'MiP', but around one fourth of malaria-positive pregnant-women were afebrile, suggesting the need for strategies to address it. CONCLUSION: The current study based on a large sample provides fresh evidence on 'MiP' in India. It used CHWs as skilled providers for large-scale screening for malaria. In high-burden areas, intermittent screening and treatment (IST) of all pregnant women can be a useful strategy in order to address 'MiP'. Pregnant women can be considered as a pertinent sentinel population for malaria. The global and national policies need to evolve concrete strategies for addressing malaria in pregnancy.

Coverage of community case management for malaria through CHWs: a quantitative assessment using primary household surveys of high-burden areas in Chhattisgarh state of India.

BACKGROUND: Community Case Management of Malaria (CCMM) has been implemented through community health workers (CHWs) in many countries. Existing studies have shown that CHWs can be viable means of implementing CCMM. However, not many studies have examined the coverage under large-scale CCMM programmes. India is a big contributor to global malaria burden. Chhattisgarh is a leading state in India in terms of malaria incidence and mortality. CCMM was implemented on a large scale through the 'mitanin' CHWs in rural Chhattisgarh from 2015. Under CCMM, 37,696 CHWs in 84 high-burden administrative blocks of the state were trained and equipped with rapid diagnostic tests (RDT), artemisinin-based combination therapy (ACT) and chloroquine. METHODS: This descriptive quantitative study assesses coverage of CCMM in detection and treatment of Malaria over three rounds of household surveys-2015, 2016 and 2018. Household-interviews covered more than 15,000 individuals in each round, using multi-stage random sampling across the 84 blocks. The main objectives were to find out the coverage in identification and treatment of malaria and the share of CHWs in them. A 15-days recall was used to find out cases of fever and healthcare sought by them. RESULTS: In 2018, 62% of febrile cases in rural population contacted CHWs. RDT, ACT and chloroquine were available with 96%, 80% and 95% of CHWs, respectively. From 2015 to 2018, the share of CHWs in testing of febrile cases increased from 34 to 70%, while it increased from 28 to 69% in treatment of malaria cases. CHWs performed better than other providers in treatment-completion and administered medication under direct observation to 72% of cases they treated. CONCLUSION: This study adds to one of the most crucial but relatively less reported area of CCMM programmes, i.e. the extent of coverage of the total febrile population by CHWs, which subsequently determines the actual coverage of case-management in malaria. Mitanin-CHWs achieved high coverage and treatment-completion rates that were rarely reported in context of large-scale CCMM elsewhere. Close to community, well-trained CHWs with sufficient supplies of rapid tests and anti-malarial drugs can play a key role in achieving the desired coverage in malaria-management.
