OBJECTIVES: To determine the extent of provider communication, predictors of good communication and the association between provider communication and patient outcomes, such as patient satisfaction, in seven sub-Saharan African countries.

DESIGN: Cross-sectional, multicountry study.

SETTING: Data from recent Service Provision Assessment (SPA) surveys from seven countries in sub-Saharan Africa. SPA surveys include assessment of facility inputs and processes as well as interviews with caretakers of sick children. These data included 3898 facilities and 4627 providers.

PARTICIPANTS: 16 352 caregivers visiting the facility for their sick children.

PRIMARY AND SECONDARY OUTCOME MEASURES: We developed an index of four recommended provider communication items for a sick child assessment based on WHO guidelines. We assessed potential predictors of provider communication and considered whether better provider communication was associated with intent to return to the facility for care.

RESULTS: The average score of the composite indicator of provider communication was low, at 35% (SD 26.9). Fifty-four per cent of caregivers reported that they were told the child's diagnosis, and only 10% reported that they were counselled on feeding for the child. Caregivers' educational attainment and provider preservice education and training in integrated management of childhood illness were associated with better communication. Private facilities and facilities with better infrastructure received higher communication scores. Caretakers reporting better communication were significantly more likely to state intent to return to the facility (relative risk: 1.19, 95% CI 1.16 to 1.22).

CONCLUSIONS: There are major deficiencies in communication during sick child visits. These are associated with lower provider education as well as less well-equipped facilities. Poor communication, in turn, is linked to lower satisfaction and intention to return to facility among caregivers of sick children. Countries should test strategies for enhancing quality of communication in their efforts to improve health outcomes and patient experience.

OBJECTIVES: The WHO called for the elimination of maternal-to-child transmission (MTCT) of HIV and syphilis, a harmonised approach for the improvement of health outcomes for mothers and children. Testing early in pregnancy, treating seropositive pregnant women and preventing syphilis reinfection can prevent MTCT of HIV and syphilis. We assessed the health and economic outcomes of a dual testing strategy in a simulated cohort of 100 000 antenatal care patients in Malawi.

METHODS: We compared four screening algorithms: (1) HIV rapid test only, (2) dual HIV and syphilis rapid tests, (3) single rapid tests for HIV and syphilis and (4) HIV rapid and syphilis laboratory tests. We calculated the expected number of adverse pregnancy outcomes, the expected costs and the expected newborn disability-adjusted life years (DALYs) for each screening algorithm. The estimated costs and DALYs for each screening algorithm were assessed from a societal perspective using Markov progression models. Additionally, we conducted a Monte Carlo multiway sensitivity analysis, allowing for ranges of inputs.

RESULTS: Our cohort decision model predicted the lowest number of adverse pregnancy outcomes in the dual HIV and syphilis rapid test strategy. Additionally, from the societal perspective, the costs of prevention and care using a dual HIV and syphilis rapid testing strategy was both the least costly ($226.92 per pregnancy) and resulted in the fewest DALYs (116 639) per 100 000 pregnancies. In the Monte Carlo simulation the dual HIV and syphilis algorithm was always cost saving and almost always reduced DALYs compared with HIV testing alone.

CONCLUSIONS: The results of the cost-effectiveness analysis showed that a dual HIV and syphilis test was cost saving compared with all other screening strategies. Updating existing prevention of mother-to-child HIV transmission programmes in Malawi and similar countries to include dual rapid testing for HIV and syphilis is likely to be advantageous.

Tropical Medicine & International Health : TM & IH 20 (8): 1057-66. https://doi.org/10.1111/tmi.12518.

OBJECTIVES: To examine factors associated with home delivery among women in Pwani Region, Tanzania, which has experienced a rapid rise in facility delivery coverage.

METHODS: Cross-sectional data from a population-based survey of women residing in rural areas of Pwani Region were linked to health facility locations. We fitted multilevel logistic models to examine individual and community factors associated with home delivery.

RESULTS: A total of 752 (27.95%) of the 2691 women who completed the survey delivered their last child at home. Women were less likely to deliver at home if they had any primary education [odds ratio (OR) 0.62; 95% confidence interval (CI): 0.50, 0.79], were primiparous (OR: 0.52; 95% CI: 0.37, 0.73), had more exposure to media (OR: 0.80; 95% CI: 0.66, 0.96) or had received more (OR: 0.78; 95% CI: 0.63, 0.96) or better quality antenatal care (ANC) services (OR: 0.48; 95% CI: 0.34, 0.67). Increased wealth was strongly associated with lower odds of home delivery (OR: 0.27; 95% CI: 0.18, 0.39), as was living in a village that grew cash crops (OR: 0.56; 95% CI: 0.35, 0.88). Farther distance to hospital, but not to lower level facilities, was associated with higher likelihood of home delivery (OR 2.49; 95% CI: 1.60, 3.88).

CONCLUSIONS: Poverty, multiparity, weak ANC and distance to hospital were associated with persistence of home delivery in a region with high coverage of facility delivery. A pro-poor path to universal coverage of safe delivery requires a greater focus on quality of care and more intensive outreach to poor and multiparous women.

Syphilis is a curable disease, yet over 10million people worldwide are infected with syphilis each year. Syphilis case finding and subsequent treatment are key steps in syphilis control and prevention efforts. The advent of rapid point-of-care tests - which require minimal equipment, are easy to perform and are relatively low cost - have the potential to improve syphilis control by allowing for more widespread testing in clinical and non-clinical settings. However, strategies to maximise the potential public health impact of those tests are needed, and those include regulatory oversight, effective supply-chain management and quality assurance systems.

PloS One 10 (8): e0135621. https://doi.org/10.1371/journal.pone.0135621.

OBJECTIVE: In order to develop patient-centered care we need to know what patients want and how changing socio-demographic factors shape their preferences.

METHODS: We fielded a structured questionnaire that included a discrete choice experiment to investigate women's preferences for place of delivery care in four rural districts of Pwani Region, Tanzania. The discrete choice experiment consisted of six attributes: kind treatment by the health worker, health worker medical knowledge, modern equipment and medicines, facility privacy, facility cleanliness, and cost of visit. Each woman received eight choice questions. The influence of potential supply- and demand- side factors on patient preferences was evaluated using mixed logit models.

RESULTS: 3,003 women participated in the discrete choice experiment (93% response rate) completing 23,947 choice tasks. The greatest predictor of health facility preference was kind treatment by doctor (β = 1.13, p<0.001), followed by having a doctor with excellent medical knowledge (β = 0.89 p<0.001) and modern medical equipment and drugs (β = 0.66 p<0.001). Preferences for all attributes except kindness and cost were changed with changes to education, primiparity, media exposure and distance to nearest hospital.

CONCLUSIONS: Care quality, both technical and interpersonal, was more important than clinic inputs such as equipment and cleanliness. These results suggest that while basic clinic infrastructure is necessary, it is not sufficient for provision of high quality, patient-centered care. There is an urgent need to build an adequate, competent, and kind health workforce to raise facility delivery and promote patient-centered care.

(2014) 2014. “Bypassing Primary Care Clinics for Childbirth: A Cross-Sectional Study in the Pwani Region, United Republic of Tanzania.”. Bulletin of the World Health Organization 92 (4): 246-53. https://doi.org/10.2471/BLT.13.126417.

OBJECTIVE: To measure the extent, determinants and results of bypassing local primary care clinics for childbirth among women in rural parts of the United Republic of Tanzania.

METHODS: Women were selected in 2012 to complete a structured interview from a full census of all 30076 households in clinic catchment areas in Pwani region. Eligibility was limited to those who had delivered between 6 weeks and 1 year before the interview, were at least 15 years old and lived within the catchment areas. Demographic and delivery care information and opinions on the quality of obstetric care were collected through interviews. Clinic characteristics were collected from staff via questionnaires. Determinants of bypassing (i.e. delivery of the youngest child at a health centre or hospital without provider referral) were analysed using multivariate logistic regression. Bypasser and non-bypasser birth experiences were compared in bivariate analyses.

FINDINGS: Of 3019 eligible women interviewed (93% response rate), 71.0% (2144) delivered in a health facility; 41.8% (794) were bypassers. Bypassing likelihood increased with primiparity (odds ratio, OR: 2.5; 95% confidence interval, CI: 1.9-3.3) and perceived poor quality at clinics (OR: 1.3; 95% CI: 1.0-1.7) and decreased if clinics recently underwent renovations (OR: 0.39; 95% CI: 0.18-0.84) and/or performed ≥ 4 obstetric signal functions (OR: 0.19; 95% CI: 0.08-0.41). Bypassers reported better quality of care on six of seven quality of care measures.

CONCLUSION: Many pregnant women, especially first-time mothers, choose to bypass local primary care clinics for childbirth. Perceived poor quality of care at clinics was an important reason for bypassing. Primary care is failing to meet the obstetric needs of many women in this rural, low-income setting.

BACKGROUND: Patients' reported opinions of the health system need to be understood in order to provide patient-centered care. We investigated determinants of women's ratings of the quality of care during their most recent facility delivery.

METHODS: We conducted a census of all deliveries in the 6 weeks to 12 months preceding the survey, in villages served by 24 primary care clinics in rural Pwani Region, Tanzania. Women who had delivered children in a study facility were included in this analysis (n = 855). We interviewed women about demographic and obstetric factors and the quality of their obstetric care using a structured questionnaire. We created a composite index of perceived quality from six quality questions. We also assessed the functioning of the local health clinic using structured surveys. We used a multi-level model to analyze factors associated with women's rating of the quality of care during delivery.

RESULTS: 14% of respondents rated the overall quality of care received during delivery as excellent. Women who listened to the radio daily reported lower quality composite scores (β: -0.99, p < 0.001). Women who reported receiving more services in ANC had higher quality scores (β: 0.46, p = 0.001), as did women receiving more delivery services (β: 0.55, p < 0.001). Women who reported disrespect and abuse during delivery had significantly lower quality scores (β: -4.13, p < 0.001).

CONCLUSIONS: A woman's expectations and prior and current experiences influence her perception of the quality of care she received. Health facility characteristics did not influence ratings of overall quality. Focusing on improving the process rather than inputs of service delivery during ANC visits and delivery may increase perceived quality of delivery care in low-resource settings.

Mbaruku, Godfrey M, Elysia Larson, Angela Kimweri, and Margaret E Kruk. (2014) 2014. “What Elements of the Work Environment Are Most Responsible for Health Worker Dissatisfaction in Rural Primary Care Clinics in Tanzania?”. Human Resources for Health 12: 38. https://doi.org/10.1186/1478-4491-12-38.

BACKGROUND: In countries with high maternal and newborn morbidity and mortality, reliable access to quality healthcare in rural areas is essential to save lives. Health workers who are satisfied with their jobs are more likely to remain in rural posts. Understanding what factors influence health workers' satisfaction can help determine where resources should be focused. Although there is a growing body of research assessing health worker satisfaction in hospitals, less is known about health worker satisfaction in rural, primary health clinics. This study explores the workplace satisfaction of health workers in primary health clinics in rural Tanzania.

METHODS: Overall, 70 health workers in rural Tanzania participated in a self-administered job satisfaction survey. We calculated mean ratings for 17 aspects of the work environment. We used principal components analysis (PCA) to identify groupings of these variables. We then examined the bivariate associations between health workers demographics and clinic characteristics and each of the satisfaction scales.

RESULTS: Results showed that 73.9% of health workers strongly agreed that they were satisfied with their job; however, only 11.6% strongly agreed that they were satisfied with their level of pay and 2.9% with the availability of equipment and supplies. Two categories of factors emerged from the PCA: the tools and infrastructure to provide care, and supportive interpersonal environment. Nurses and medical attendants (compared to clinical officers) and older health workers had higher satisfaction scale ratings.

CONCLUSIONS: Two dimensions of health workers' work environment, namely infrastructure and supportive interpersonal work environment, explained much of the variation in satisfaction among rural Tanzanian health workers in primary health clinics. Health workers were generally more satisfied with supportive interpersonal relationships than with the infrastructure. Human resource policies should consider how to improve these two aspects of work as a means for improving health worker morale and potentially rural attrition.

International Journal of STD & AIDS 25 (9): 636-42. https://doi.org/10.1177/0956462413515639.

Our aim was to describe the association between increasing access to antiretroviral therapy and all-cause mortality in South Africa from 2005 to 2009. We undertook a longitudinal, population-level study, using antiretroviral monitoring data reported by PEPFAR implementing partners and province-level and national all-cause mortality records from Statistics South Africa (provider of official South African government statistics) to analyse the association between antiretroviral therapy and mortality. Using mixed effects models with a random intercept for province, we estimated the contemporaneous and lagging association between antiretroviral therapy and all-cause mortality in South Africa. We also conducted subgroup analyses and estimated the number of deaths averted. For each 100 HIV-infected individuals on antiretroviral therapy reported by PEPFAR implementing partners in South African treatment programmes, there was an associated 2.9 fewer deaths that year (95% CI: 1.5, 4.2) and 6.3 fewer deaths the following year (95% CI: 4.6, 8.0). The associated decrease in mortality the year after treatment reporting was seen in both adults and children, and men and women. Treatment provided from 2005 to 2008 was associated with 28,305 deaths averted from 2006 to 2009. The scale-up of antiretroviral therapy in South Africa was associated with a significant reduction in national all-cause mortality.
