Improving the quality of childbirth services in Zambia through introduction of the Safe Childbirth Checklist and systems-focused mentorship.

Although strong evidence exists about the effectiveness of basic childbirth services in reducing maternal and newborn mortality, these services are not provided in every childbirth, even those at health facilities. The WHO Safe Childbirth Checklist (SCC) was developed as a job aide to remind health workers of evidenced-based practices to be provided at specific points in the childbirth process. The Zambian government requested context-specific evidence on the feasibility and outcomes associated with introducing the checklist and related mentorship. A study was conducted on use of the SCC in four facilities in Nchelenge District of Zambia. Observations of childbirth services were conducted just before and six months after the introduction of the intervention. Observers used a structured tool to record adherence to essential services indicated on the checklist. The primary outcome of interest was the change in the average proportion of essential childbirth practices completed. Feedback questionnaires were administered to health workers before and six months after the intervention. At baseline and endline, 108 and 148 pause points were observed, respectively. There was an increase from 57% to 76% of tasks performed (p = 0.04). Considering only these cases where necessary supplies were available, health workers completed 60% of associated tasks at baseline compared to 84% at endline (p<0.01). Some tasks, such as taking an infant's temperature and hand washing, were never or rarely performed at baseline. Feedback from the health workers indicated that nearly all health workers agreed or strongly agreed with positive statements about the intervention. The performance of health workers in Zambia in completing essential practices in childbirth was low at baseline but improvements were observed with the introduction of the SCC and mentorship. Our results suggest that such interventions could improve quality of care for facility-based childbirth. However, national-level commitment to ensuring availability of trained staff and supplies is essential for success.

Impact of the Umoyo mother-infant pair model on HIV-positive mothers' social support, perceived stigma and 12-month retention of their HIV-exposed infants in PMTCT care: evidence from a cluster randomized controlled trial in Zambia.

BACKGROUND: Public health systems in resource-constrained settings have a critical role to play in the elimination of HIV transmission but are often financially constrained. This study is an evaluation of a mother-infant-pair model called "Umoyo," which was designed to be low cost and scalable in a public health system. Facilities with the Umoyo model dedicate a clinic day to provide services to only HIV-exposed infants (HEIs) and their mothers. Such models are in operation with reported success in Zambia but have not been rigorously tested. This work establishes whether the Umoyo model would improve 12-month retention of HEIs. METHODS: A cluster randomized trial including 28 facilities was conducted across two provinces of Zambia to investigate the impact on 12-month retention of HEIs in care. These facilities were offering Prevention of Mother-to-Child-Transmission (PMTCT) services and supported by the same implementing partner. Randomization was achieved by use of the covariate-constrained optimization technique. Secondary outcomes included the impact of Umoyo clinics on social support and perceived HIV stigma among mothers. For each of the outcomes, a difference-in-difference analysis was conducted at the facility level using the unweighted t test. RESULTS: From 13 control (12-month retention at endline: 45%) and 11 intervention facilities (12-month retention at endline: 33%), it was found that Umoyo clinics had no impact on 12-month retention of HEIs in the t test (- 11%; 99% CI - 40.1%, 17.2%). Regarding social support and stigma, the un-weighted t test showed no impact though sensitivity tests showed that Umoyo had an impact on increasing social support (0.31; 99% CI 0.08, 0.54) and reducing perceived stigma from health care workers (- 0.27; 99% CI - 0.46, - 0.08). CONCLUSION: The Umoyo approach of having a dedicated clinic day for HEIs and their mothers did not improve retention of HEIs though there are indications that it can increase social support among mothers and reduce stigma. Without further support to the underlying health system, based on the evidence generated through this evaluation, the Umoyo clinic day approach on its own is not considered an effective intervention to increase retention of HIV-exposed infants.

Impact of the Safe Childbirth Checklist on health worker childbirth practices in Luapula province of Zambia: a pre-post study.

BACKGROUND: A strong evidence base exists regarding routine and emergency services that can effectively prevent or reduce maternal and new-born mortality. However, even when skilled providers care for women in labour, many of the recommended services are not provided, despite being available. Barriers to the provision of appropriate childbirth services may include lack of availability of supplies, limited health worker knowledge and confidence, or inadequate time. The WHO Safe Childbirth Checklist (SCC) includes reminders for evidenced-based practices at specific points in the childbirth process. Zambia is currently considering nation-wide adoption of the SCC, but there is a need for context-specific evidence. Beginning in September 2017, a program is being implemented in Nchelenge District to pilot use of the SCC, along with coaching that focuses on strengthening the systems that allow the essential practices in childbirth to be performed. METHODS: This study will use a pre-post study design to measure health worker adherence to the essential practices for delivery care outlined in the SCC. Data will be collected through observations of health workers as they care for mothers during childbirth at four facilities. Data collection will take place before the start of the intervention, at 3 months, and at 6 months post-intervention. The primary outcome interest is the change in the average proportion of essential childbirth practices completed. A health worker questionnaire will be administered at the time that the SCC is introduced and 6 months later to gather their perspectives on incorporating the SCC into clinical practice in Zambia. DISCUSSION: Findings are expected to inform plans for introducing the SCC in Zambia. This evaluation will aim to understand uptake and impact of the SCC and associated coaching in the context of a basic level of mentorship that the government could feasibly provide at a national scale.

Impact of passenger engagement through road safety bus stickers in public service vehicles on road traffic crashes in Zambia: a randomized controlled trial.

BACKGROUND: Road Traffic Crashes (RTCs) are the third highest cause of death in Zambia, claiming about 2000 lives annually, with pedestrians and cyclists being the most vulnerable. Human error accounts for 87.3% of RTCs. Minibus and big bus public service vehicles (PSVs) are among the common vehicle types involved in these crashes. Given the alarmingly high rate of road traffic crashes involving PSV minibuses and big buses within Zambia, there is a need to mitigate this through innovative solutions. In other settings, it has been shown that stickers in PSVs encouraging passengers to speak out against reckless driving can reduce RTCs, but it is unclear whether such an intervention could work in Zambia. Based on this evidence, the Zambia Road Transport and Safety Agency (RTSA) has developed a road safety bus sticker campaign for PSVs and before national scale-up, RTSA is interested in evidence of the impact of these stickers. METHODS: This evaluation will be a stratified two-arm randomized controlled trial with a one-to-one ratio. The sample will be stratified by vehicle type, thus creating a two-arm trial for minibuses and a separate two-arm trial for big buses. The sample will include 2110 minibuses and 300 big buses from four towns in Zambia. The primary outcome of interest will be the difference in the rate of RTCs over a 14-month period (7-months before the intervention and 7 months after) between buses with and without the new RTSA road safety bus stickers. DISCUSSION: This study will provide evidence on the impact of the Zambian sticker program on road traffic crashes as implemented through minibuses and big buses, that can help inform the scale up of a national 'Zambia road safety bus sticker campaign'.

An exploration of facilitators and challenges in the scale-up of a national, public sector community health worker cadre in Zambia: a qualitative study.

BACKGROUND: In 2010 a public sector cadre of community health workers called Community Health Assistants (CHAs) was created in Zambia through the National Community Health Worker Strategy to expand access to health services. This cadre continues to be scaled up to meet the growing demands of Zambia's rural population. We summarize factors that have facilitated the scale-up of the CHA program into a nationwide CHW cadre and the challenges of introducing and institutionalizing the cadre within the Zambian health system. METHODS: Semi-structured, individual interviews were held across 5 districts with 16 CHAs and 6 CHA supervisors, and 10 focus group discussions were held with 93 community members. Audio recordings of interviews and focus group discussions were transcribed and thematically coded using Dedoose web-based software. RESULTS: The study showed that the CHAs play a critical role in providing a wide range of services at the community level, as described by supervisors and community members. Some challenges still remain, that may inhibit the CHAs ability to provide health services effectively. In particular, the respondents highlighted infrequent supervision, lack of medical and non-medical supplies for outreach services, and challenges with the mobile data reporting system. CONCLUSIONS: The study shows that in order to optimize the impact of CHAs or other community health workers, key health-system support structures need to be functioning effectively, such as supervision, community surveillance systems, supplies, and reporting. The Ministry of Health with support from partners are currently addressing these challenges through nationwide supervisor and community data trainings, as well as advocating for adding primary health care as a specific focus area in the new National Health Strategy Plan 2017-2021. This study contributes to the evidence base on the introduction of formalized community health worker cadres in developing countries.

Implementation of the Community Health Assistant (CHA) Cadre in Zambia: A Process Evaluation to Guide Future Scale-Up Decisions.

Universal health coverage requires an adequate health workforce, including community health workers (CHWs) to reach rural communities. To improve healthcare access in rural areas, in 2010 the Government of Zambia implemented a national CHW strategy that introduced a new cadre of healthcare workers called community health assistants (CHAs). After 1 year of training the pilot class of 307 CHAs deployed in September 2012. This paper presents findings from a process evaluation of the barriers and facilitators of implementation of the CHA pilot, along with how evidence was used to guide ongoing implementation and scale-up decisions. Qualitative inquiry was used to assess implementation during the first 6 months of the program rollout, with 43 in-depth individual and 32 small group interviews across five respondent types: CHAs, supervisors, volunteer CHWs, community members, and district leadership. Potential 'implementation moderators' were explored using deductive coding and thematic analysis of participant perspectives on community acceptance of CHAs, supervision support mechanisms, and coordination with volunteer CHWs, and health system integration of a new cadre. Community acceptance of CHAs was generally high, but coordination between CHAs and existing volunteer CHWs presented some challenges. The supervision support system was found to be inconsistent, limiting assurance of consistent quality care delivered by CHAs. Underlying health system weaknesses regarding drug supply and salary payments furthermore hindered incorporation of a new cadre within the national health system. Recommendations for implementation and future scale based on the process evaluation findings are discussed.
