Tropical Medicine & International Health : TM & IH 24 (5): 636-46. https://doi.org/10.1111/tmi.13220.

OBJECTIVES: Reduction in maternal and newborn mortality requires that women deliver in high quality health facilities. However, many facilities provide sub-optimal quality of care, which may be a reason for less than universal facility utilisation. We assessed the impact of a quality improvement project on facility utilisation for childbirth.

METHODS: In this cluster-randomised experiment in four rural districts in Tanzania, 12 primary care clinics and their catchment areas received a quality improvement intervention consisting of in-service training, mentoring and supportive supervision, infrastructure support, and peer outreach, while 12 facilities and their catchment areas functioned as controls. We conducted a census of all deliveries within the catchment area and used difference-in-differences analysis to determine the intervention's effect on facility utilisation for childbirth. We conducted a secondary analysis of utilisation among women whose prior delivery was at home. We further investigated mechanisms for increased facility utilisation.

RESULTS: The intervention led to an increase in facility births of 6.7 percentage points from a baseline of 72% (95% Confidence Interval: 0.6, 12.8). The intervention increased facility delivery among women with past home deliveries by 18.3 percentage points (95% CI: 10.1, 26.6). Antenatal quality increased in intervention facilities with providers performing an additional 0.5 actions across the full population and 0.8 actions for the home delivery subgroup.

CONCLUSIONS: We attribute the increased use of facilities to better antenatal quality. This increased utilisation would lead to lower maternal mortality only in the presence of improvement in care quality.

In 2018, three independent reports were published, emphasizing the need for attention to, and improvements in, quality of care to achieve effective universal health coverage. A key aspect of high quality health care and health systems is that they are person-centred, a characteristic that is at the same time intrinsically important (all individuals have the right to be treated with dignity and respect) and instrumentally important (person-centred care is associated with improved health-care utilization and health outcomes). Following calls to make 2019 a year of action, we provide guidance to policy-makers, researchers and implementers on how they can take on the task of measuring person-centred care. Theoretically, measures of person-centred care allow quality improvement efforts to be evaluated and ensure that health systems are accountable to those they aim to serve. However, in practice, the utility of these measures is limited by lack of clarity and precision in designing and by using measures for different aspects of person-centeredness. We discuss the distinction between two broad categories of measures of patient-centred care: patient experience and patient satisfaction. We frame our discussion of these measures around three key questions: (i) how will the results of this measure be used?; (ii) how will patient subjectivity be accounted for?; and (iii) is this measure validated or tested? By addressing these issues during the design phase, researchers will increase the usability of their measures.

Human Resources for Health 17 (1): 23. https://doi.org/10.1186/s12960-019-0355-7.

BACKGROUND: There is a dearth of evidence on the causal effects of different care delivery approaches on health system satisfaction. A better understanding of public satisfaction with the health system is particularly important within the context of task shifting to community health workers (CHWs). This paper determines the effects of a CHW program focused on maternal health services on public satisfaction with the health system among women who are pregnant or have recently delivered.

METHODS: From January 2013 to April 2014, we carried out a cluster-randomized controlled health system implementation trial of a CHW program. Sixty wards in Dar es Salaam, Tanzania, were randomly allocated to either a maternal health CHW program (36 wards) or the standard of care (24 wards). From May to August 2014, we interviewed a random sample of women who were either currently pregnant or had recently delivered a child. We used five-level Likert scales to assess women's satisfaction with the CHW program and with the public-sector health system in Dar es Salaam.

RESULTS: In total, 2329 women participated in the survey (response rate 90.2%). Households in intervention areas were 2.3 times as likely as households in control areas to have ever received a CHW visit (95% CI 1.8, 3.0). The intervention led to a 16-percentage-point increase in women reporting they were satisfied or very satisfied with the CHW program (95% CI 3, 30) and a 15-percentage-point increase in satisfaction with the public-sector health system (95% CI 3, 27).

CONCLUSIONS: A CHW program for maternal and child health in Tanzania achieved better public satisfaction than the standard CHW program. Policy-makers and implementers who are involved in designing and organizing CHW programs should consider the potential positive impact of the program on public satisfaction.

Frontiers in Public Health 6: 273. https://doi.org/10.3389/fpubh.2018.00273.

Background: Poor health system experiences negatively affect the lives of poor people throughout the world. In East Africa, there is a growing body of evidence of poor quality care that in some cases is so poor that it is disrespectful or abusive. This study will assess whether community feedback through report cards (with and without non-financial rewards) can improve patient experience, which includes aspects of patient dignity, autonomy, confidentiality, communication, timely attention, quality of basic amenities, and social support. Methods/Design: This cluster-randomized controlled study will randomize 75 primary health care facilities in rural Pwani Region, Tanzania to one of three arms: private feedback (intervention), social recognition reward through public reporting (intervention), or no feedback (control). Within both intervention arms, we will give the providers at the study facilities feedback on the quality of patient experience the facility provides (aggregate results from all providers) using data from patient surveys. The quality indicators that we report will address specific experiences, be observable by patients, fall into well-identified domains of patient experience, and be within the realm of action by healthcare providers. For example, we will measure the proportion of patients who report that providers definitely "explained things in a way that was easy to understand." This feedback will be delivered by a medical doctor to all the providers at the facility in a small group session. A formal discussion guide will be used. Facilities randomized to the social recognition intervention reward arm will have two additional opportunities for social recognition. First, a poster that displays their achieved level of patient experience will be publicly posted at the health facility and village government offices. Second, recognition from senior officials at the local NGO and/or the Ministry of Health will be given to the facility with the best or most-improved patient experience ratings at endline. We will use surveys with parents/guardians of sick children to measure patient experience, and surveys with healthcare providers to assess potential mechanisms of effect. Conclusion: Results from this study will provide evidence for whether, and through what mechanisms, patient reported feedback can affect interpersonal quality of care.

Geldsetzer, Pascal, Joel M Francis, Nzovu Ulenga, David Sando, Irene A Lema, Eric Mboggo, Maria Vaikath, et al. (2017) 2017. “The Impact of Community Health Worker-Led Home Delivery of Antiretroviral Therapy on Virological Suppression: A Non-Inferiority Cluster-Randomized Health Systems Trial in Dar Es Salaam, Tanzania.”. BMC Health Services Research 17 (1): 160. https://doi.org/10.1186/s12913-017-2032-7.

BACKGROUND: Home delivery of antiretroviral therapy (ART) by community health workers (CHWs) may improve ART retention by reducing the time burden and out-of-pocket expenditures to regularly attend an ART clinic. In addition, ART home delivery may shorten waiting times and improve quality of care for those in facility-based care by decongesting ART clinics. This trial aims to determine whether ART home delivery for patients who are clinically stable on ART combined with facility-based care for those who are not stable on ART is non-inferior to the standard of care (facility-based care for all ART patients) in achieving and maintaining virological suppression.

METHODS: This is a non-inferiority cluster-randomized trial set in Dar es Salaam, Tanzania. A cluster is one of 48 healthcare facilities with its surrounding catchment area. 24 clusters were randomized to ART home delivery and 24 to the standard of care. The intervention consists of home visits by CHWs to provide counseling and deliver ART to patients who are stable on ART, while the control is the standard of care (facility-based ART and CHW home visits without ART home delivery). In addition, half of the healthcare facilities in each study arm were randomized to standard counseling during home visits (covering family planning, prevention of HIV transmission, and ART adherence), and half to standard plus nutrition counseling (covering food production and dietary advice). The non-inferiority design applies to the endpoints of the ART home delivery trial; the primary endpoint is the proportion of ART patients at a healthcare facility who are virally suppressed at the end of the study period. The margin of non-inferiority for this primary endpoint was set at nine percentage points.

DISCUSSION: As the number of ART patients in sub-Saharan Africa is expected to rise, this trial provides causal evidence on the effectiveness of a home-based care model that could decongest ART clinics and reduce patients' healthcare expenditures. More broadly, this trial will inform the increasing policy interest in task-shifting of chronic disease care from facility- to community-based healthcare workers.

International Journal for Quality in Health Care : Journal of the International Society for Quality in Health Care 29 (1): 104-10. https://doi.org/10.1093/intqhc/mzw141.

OBJECTIVE: To determine the effective coverage of obstetric care in a rural Tanzanian region and to assess differences in effective coverage by wealth.

DESIGN: Cross-sectional structured interviews.

SETTING: Pwani Region, Tanzania.

PARTICIPANTS: The study includes 24 rural, government-managed, primary healthcare clinics and their catchment populations. From January-April 2016, we conducted a household survey of a census of women with recent deliveries, health worker knowledge surveys and facility audits.

MAIN OUTCOME MEASURES: We explored the proportion of women receiving quality care through the cascade and conducted an equity analysis by wealth.

RESULTS: In total, 2,910 of 3,564 women (81.6%) reported delivering their most recent child in a health facility, 1,096 of whom delivered in a study facility. Using a minimum threshold of quality, the effective coverage of obstetric care was 25%. Quality was lowest in the emergency care dimensions, with the average score on the provider knowledge tests at 47% and the average provision of basic emergency obstetric services below 50%. The wealthiest 20% of women were 4.1 times as likely to deliver in facilities offering at least the minimum threshold of quality care through the cascade compared to the poorest 80% of women (95% confidence interval: 1.5-11.3).

CONCLUSIONS: Effective coverage of delivery care is very low, particularly among poorer women. Health worker knowledge caused the sharpest decline in effective coverage. Measures of effective coverage are a better performance measure of under-resourced health systems than utilization. Equity analyses can further identify important discrepancies in quality across socio-economic levels.

(2017) 2017. “Beyond the Crisis: Did the Ebola Epidemic Improve Resilience of Liberia’s Health System?”. Health Policy and Planning 32 (suppl_3): iii40-iii47. https://doi.org/10.1093/heapol/czx109.

Resilience was widely identified as a critical attribute for strong health systems following the 2014-15 West Africa Ebola epidemic. In Liberia, Sierra Leone and Guinea, struggles to control the disease and suspension of the operation of many health services demonstrated that health systems must plan for resilience long before a crisis. However, the operational elements of resilience and ways that a crisis experience can shape resilience are not well described in the literature. To understand how a health system adapts to crisis and how the priorities of different health system actors influence this response we conducted interviews with global, national, and local respondents in Liberia between July and September 2015 (n = 108), several months after the country was first declared Ebola-free. We found that health system resilience functions prioritized by global and national actors improved to a greater extent than those valued by community leaders and local health actors over the course of the epidemic. Although the Ebola epidemic stimulated some positive adaptations in Liberia's health system, building a truly resilient health system will require longer-term investments and sustained attention long beyond the crisis.

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.

Maternal and Child Health Journal 21 (3): 407-13. https://doi.org/10.1007/s10995-016-2229-0.

Objectives To assess the prevalence of high blood pressure amongst postpartum women in rural Tanzania, and to explore factors associated with hypertension prevalence, awareness, treatment, and control. Methods 1849 women in Tanzania's Pwani Region who delivered a child in the prior year participated in the study. We measured blood pressure, administered a structured questionnaire and assessed factors associated with the prevalence, awareness, treatment, and control of hypertension (HTN) using bivariable and multivariable logistic regressions. Findings 26.7% of women had high blood pressure and/or were taking antihypertensive medication. Women were on average 27.5 years old (range 15-54). Nearly all women (99.5%) reported contact with the health system during their pregnancy and delivery, with an average of 5.2 visits for their own care in the past year. Only 23.5% of those with HTN were aware of their diagnosis, 17.4% were taking medication, and only 10.5% had controlled blood pressure. In multivariable analysis, facility delivery, health insurance, and increased distance from a hospital were associated with increased likelihood of HTN awareness; facility delivery and hospital distance were associated with current hypertensive treatment; younger age and increased hospital distance were associated with control of HTN. Conclusion The prevalence of high blood pressure in this postpartum population was high, and despite frequent recent contacts with the health system, awareness, treatment and control of HTN were low. These findings highlight an important missed opportunity to improve women's health during antenatal and postnatal care.
