Acceptability of option B+ among HIV positive women receiving antenatal and postnatal care services in selected health centre's in Lusaka.

BACKGROUND: In 2013, Zambia accepted the immediate operationalization of Option B+, a policy used to try and eliminate mother to child transmission. This policy requires all HIV-positive pregnant and breastfeeding women to initiate antiretroviral treatment for life regardless of CD4 count. However, not all HIV positive women accept treatment for life. This study aimed to investigate acceptability of lifelong ART (Option B+) among HIV positive women receiving antenatal and postnatal services at the university teaching hospital and Lusaka urban city clinics. METHODS: This was a cross sectional study conducted in November, 2016 to March 2017. The study population comprised of HIV positive women in their reproductive age (15-49 years). A Structured questionnaire was used to collect data in a face to face interview with the participants. Data was entered in EpiData version 3.1 and analysed using Stata version 13. Multivariate logistic regression analysis was performed to determine predictors of acceptability. RESULTS: Overall, 427 women participated in this study. Their mean age was 30 years. Of the 427, over half (54%) had inadequate knowledge and about 30% of the women in the study still experience stigma and discrimination.63.2% of the women had good attitude towards Option B+ and overall, the majority (77.8%) were willing to accept antiretroviral therapy for life. Multivariate analysis showed that only women with good attitude were 9.4 times more likely to accept Option B+ than those with a bad attitude [OR: 9.4: 95%CI, 5.8-15.2)]. CONCLUSION: This study showed that in general, women accepted initiation of Option B+. However, there is still a gap in the level of knowledge of Option B+ as well as stigma and discrimination in some communities, hence there is need to intensify programs that are aimed at educating the community on the importance of ART for life, combat stigma and discrimination and consequently promote acceptability of Option B+.

Uptake of intermittent preventive treatment for malaria during pregnancy with Sulphadoxine-Pyrimethamine (IPTp-SP) among postpartum women in Zomba District, Malawi: a cross-sectional study.

BACKGROUND: Malaria in pregnancy causes adverse birth outcomes. Intermittent preventive treatment of malaria during pregnancy with sulphadoxine-pyrimethamine (IPTp-SP) is recommended as a chemoprevention therapy. Zomba district IPTp uptake falls far below the national average. The study was conducted to assess determinants of IPTp-SP uptake during pregnancy among postpartum women in Zomba district after adoption of new IPTp-SP policy in 2014. METHODS: This was a cross-sectional survey. Two public health facilities (HFs) were randomly selected from urban and rural areas in Zomba district. Study participants were postpartum women selected by using exit poll method from HFs. A total of 463 postpartum women were interviewed using structured questionnaire. Bivariate and multiple logistic regression was used in data analysis. RESULTS: Out of all the enrolled participants (n = 463), 92% women had complete information for analysis. Of these, (n = 426) women, 127 (29.8%, 95% CI: 25.6%-34.3%) received three or more doses of SP, 299 (70.2%, 95% CI: 65.7%-74.4%) received two or less doses. Women receiving SP from rural HF were less likely to get at least three doses of SP than urban women, (AOR = 0.31, 95% CI 0.13-0.70); Others less likely were those with three or few antenatal care (ANC) visits versus four or more visits (AOR = 0.29, 95% CI 0.18-0.48); not taking SP under direct observation therapy (DOT) (AOR = 0.18, 95% CI (0.05-0.63). CONCLUSIONS: There is low utilisation of at least three doses of SP in this population and this seems to be associated with the number of ANC visits and use of DOTs. These determinants may therefore be important in shaping interventions aimed at increasing the uptake of IPTp in this district. In addition, the rural urban differential suggests the need for further research to understand the barriers and enablers of uptake in each context in order to improve the health of the community.

Towards a framework for analyzing determinants of performance of community health workers in malaria prevention and control: a systematic review.

BACKGROUND: Community health workers (CHWs) are an important human resource in improving coverage of and success to interventions aimed at reducing malaria incidence. Evidence suggests that the performance of CHWs in malaria programs varies in different contexts. However, comprehensive frameworks, based on systematic reviews, to guide the analysis of determinants of performance of CHWs in malaria prevention and control programs are lacking. METHODS: We systematically searched Google Scholar, Science Direct, and PubMed including reference lists that had English language publications. We included 16 full text articles that evaluated CHW performance in malaria control. Search terms were used and studies that had performance as an outcome of interest attributed to community-based interventions done by CHWs were included. RESULTS: Sixteen studies were included in the final review and were mostly on malaria Rapid Diagnosis and Treatment, as well as adherence to referral guidelines. Factors determining performance and effective implementation of CHW malaria programs included health system factors such as nature of training of CHWs; type of supervision including feedback process; availability of stocks, supplies, and job aids; nature of work environment and reporting systems; availability of financial resources and transport systems; types of remuneration; health staff confidence in CHWs; and workload. In addition, community dynamics such as nature of community connectedness and support from the community and utilization of services by the community also influenced performance. Furthermore, community health worker characteristics such marital status, sex, and CHW confidence levels also shaped CHW performance. CONCLUSIONS: Effectively analyzing and promoting the performance of CHWs in malaria prevention and control programs may require adopting a framework that considers health systems and community factors as well as community health worker characteristics.

A systematic review of factors that shape implementation of mass drug administration for lymphatic filariasis in sub-Saharan Africa.

BACKGROUND: Understanding factors surrounding the implementation process of mass drug administration for lymphatic filariasis (MDA for LF) elimination programmes is critical for successful implementation of similar interventions. The sub-Saharan Africa (SSA) region records the second highest prevalence of the disease and subsequently several countries have initiated and implemented MDA for LF. Systematic reviews have largely focused on factors that affect coverage and compliance, with less attention on the implementation of MDA for LF activities. This review therefore seeks to document facilitators and barriers to implementation of MDA for LF in sub-Saharan Africa. METHODS: A systematic search of databases PubMed, Science Direct and Google Scholar was conducted. English peer-reviewed publications focusing on implementation of MDA for LF from 2000 to 2016 were considered for analysis. Using thematic analysis, we synthesized the final 18 articles to identify key facilitators and barriers to MDA for LF programme implementation. RESULTS: The main factors facilitating implementation of MDA for LF programmes were awareness creation through innovative community health education programmes, creation of partnerships and collaborations, integration with existing programmes, creation of morbidity management programmes, motivation of community drug distributors (CDDs) through incentives and training, and management of adverse effects. Barriers to implementation included the lack of geographical demarcations and unregistered migrations into rapidly urbanizing areas, major disease outbreaks like the Ebola virus disease in West Africa, delayed drug deliveries at both country and community levels, inappropriate drug delivery strategies, limited number of drug distributors and the large number of households allocated for drug distribution. CONCLUSION: Mass drug administration for lymphatic filariasis elimination programmes should design their implementation strategies differently based on specific contextual factors to improve implementation outcomes. Successfully achieving this requires undertaking formative research on the possible constraining and inhibiting factors, and incorporating the findings in the design and implementation of MDA for LF.

Acceptability and associated factors of indoor residual spraying for malaria control by households in Luangwa district of Zambia: A multilevel analysis.

The global burden of malaria has increased from 227 million cases in 2019 to 247 million cases in 2020. Indoor residual spraying (IRS) remains one of the most effective control strategies for malaria. The current study sought to measure the acceptability level and associated factors of indoor residual spraying. A cross sectional study was conducted from October to November 2020 in sixteen urban and rural communities of Luangwa district using a cluster sampling method, Multilevel analysis was used to account for the hierarchical structure of the data. The acceptability level of indoor residual spraying among household heads was relatively high at 87%. Individuals who felt the timing was not appropriate were associated with decreased odds of accepting IRS (AOR = 0.55, 95% CI: 0.20-0.86). Positive attitude was associated with increased odds of accepting IRS (AOR = 29.34, 95% CI: 11.14-77.30). High acceptability level was associated with unemployment (AOR = 1.92, 95% CI: 1.07-3.44). There were no associations found between acceptability levels and community-level factors such as information, education, communication dissemination, awareness achieved through door-to-door sensitization, and public address system. Acceptability level of indoor residual spraying was relatively high among households of Luangwa District suggesting that the interventions are more acceptable which is essential in reaching malaria elimination by 2030. Finding that community factors known to influence acceptability such as information, education and communication as well as awareness were not important to influencing acceptability suggests need for reinforcing messages related to indoor residual spraying and redefining the community sensitization approaches to make indoor residual spraying more acceptable.

Evaluation of Bacterial Contamination in Dressed Chickens in Lusaka Abattoirs.

Objective: The aim of this study was to evaluate bacterial contamination and the risk factors associated with contamination of poultry during processing. Despite the rapid growth of the poultry industry, the presence of high levels of pathogenic bacteria contaminants, such as Escherichia coli and Salmonella, pose serious public health concerns in dressed chickens. These infections negatively affect the product's shelf life. Methods: A cross sectional design was used to study two main poultry abattoirs in Lusaka. The processing line was used to collect biological samples along with the acquisition of risk-associated data using a structured questionnaire. Data collected both from biological sources and the risk analysis were entered into Excel and analysed in STATA version 14 for windows. Results: Escherichia coli and Salmonella contamination was detected in 70 and 2.5% of the selected dressed chickens (n = 80), respectively. The number of total coliforms and Escherichia coli were observed to be significantly higher in samples from washed carcasses than pre-washed carcasses (65 and 35%, respectively). In addition, this study revealed that among the anthropogenic and exposure risk factors, bacterial contamination levels resulted mainly from a lack of hygienic practices. This included hand washing and an increased frequency of slaughters per day (>15,000). Conclusion: This study indicates that the water used for dressing chickens is probably the major cause of high levels of cross-contamination. The results also highlight the issues that need to be addressed to improve environmental and carcass hygiene in a poultry abattoir. Significance: Critical findings in this study are that contamination sources may be variable and hygienic practices may play a major role. In this particular study, the reuse of contaminated water was a case in point. Accordingly, there is need for both the water source and the water being used for processing to be tested.
