Program evaluation of an ORS and zinc scale-up program in 8 Nigerian states.

BACKGROUND: In Nigeria, diarrhea is the second leading killer of children under five. Between 2012-2017, the Clinton Health Access Initiative, Inc. (CHAI) and the Government of Nigeria implemented a comprehensive program in eight states aimed at increasing the percentage of children under five with diarrhea who were treated with zinc and oral rehydration solution (ORS). The program addressed demand, supply, and policy barriers to ORS and zinc uptake through interventions in both public and private sectors. The interventions included: (1) policy revision and partner coordination; (2) market shaping to improve availability of affordable, high-quality ORS and zinc; (3) provider training and mentoring; and (4) caregiver demand generation. METHODS: We conducted cross-sectional household surveys in program states at baseline, midline, and endline and constructed logistic regression models with generalized estimating equations to assess changes in ORS and zinc treatment during the program period. RESULTS: In descriptive analysis, we found 38% (95% CI = 34%-42%) received ORS at baseline and 4% (95% CI = 3%-5%) received both ORS and zinc. At endline, we found 55% (95% CI = 51%-58%) received ORS and 30% (95% CI = 27%-33%) received both ORS and zinc. Adjusting for other covariates, the odds of diarrhea being treated with ORS were 1.88 (95% CI = 1.46, 2.43) times greater at endline. The odds of diarrhea being treated with ORS and zinc combined were 15.14 (95% CI = 9.82, 23.34) times greater at endline. When we include the interaction term to investigate whether the odds ratios between the endline and baseline survey were modified by source of care, we found statistically significant results among diarrhea episodes that sought care in the public and private sector. Among cases that sought care in the public sector, the predictive probability of treatment with ORS increased from 57% (95% CI = 50%-65%) to 83% (95% CI = 79%-87%). Among cases that sought care in the private sector, the predictive probability increased from 41% (95% CI = 34%-48%) to 58% (95% CI = 54%-63%). CONCLUSIONS: Use of ORS and combined ORS and zinc for treatment of diarrhea significantly increased in program states during the program period.

Effectiveness of the Diagnose-Intervene- Verify-Adjust (DIVA) model for integrated primary healthcare planning and performance improvement: an embedded mixed methods evaluation in Kaduna state, Nigeria.

OBJECTIVES: This study evaluates the real-world effectiveness of Diagnose-Intervene-Verify-Adjust (DIVA), an innovative quality improvement mode, in improving primary healthcare (PHC) bottlenecks impeding health system performance in Kaduna, a northern Nigerian state. DESIGN: An embedded mixed method study design involving participant observation. SETTING: PHCs in 23 local government areas of Kaduna state, Nigeria. PARTICIPANTS: 138 PHC managers across the state (PHC directors and programme managers in the 23 local governments). INTERVENTION: DIVA is a four-step improvement model in which 'Diagnose' identifies constraints to effective coverage, 'Intervene' develops/implements action plans addressing constraints, while 'Verify/Adjust' monitor performance and revise plans. PRIMARY AND SECONDARY OUTCOME MEASURES: The model, as adapted in Nigeria, is designed to evaluate and improve the availability of health commodities, human resources, geographical accessibility, acceptability, continuous utilisation and quality of four PHC interventions (immunisation, integrated management of childhood illnesses, antenatal care and skilled birth attendance). RESULTS: 183 bottlenecks were identified by local government teams across all interventions in 2013. 41% of bottlenecks concern human resources. Geographical access and availability of commodities ranked least. Availability of commodities was the most improved determinant although among the least constrained, probably indicating skewed implementation of operational plans. 1562 activities were planned to address identified bottlenecks in the state, of which only 568 (36%) were completely implemented CONCLUSION: Our study demonstrates that PHC planning using the DIVA model can potentially improve health system performance. However, effective implementation is critical and may require some central government oversight.

Pay for performance in Nigeria: the influence of context and implementation on results.

Pay-for-performance (P4P) has recently been introduced in Nigeria to improve quality of health services. Its early results show significant variation between implementation sites. Literature suggests this might be explained by differences in design, context and implementation of the scheme. This study aimed to explore how context and implementation influence P4P in Nigeria. Semi-structured in-depth interviews with 36 health workers explored their views and experiences on how contextual and implementation factors influenced the impact of the P4P scheme. Data were analysed using the framework approach. Four themes captured the views and experiences of participants. Uncertainty of earning the incentive and inadequate infrastructure reduced health worker motivation and performance results; whilst adequate health worker understanding of the scheme and good managerial skills (health facility level) improved motivation and performance. Minimising delays in incentive payments, effective communication and improving the health workers understanding of the P4P scheme are likely to improve the outcomes of pay for performance programmes, independent of their design.

Putting Institutions at the Center of Primary Health Care Reforms: Experience from Implementation in Three States in Nigeria.

Abstract-Within the last two decades, the Nigerian government has committed to strengthening its primary health care system, through reforms addressing institutional restructuring, deepening decentralized governance, and the incorporation of an alternative health care financing strategy. One of these reforms prescribed the establishment of state primary health care agencies/boards (SPHCDBs) as an integral part of the national health system, with the principal responsibility "for the coordination of planning, budgeting, provision and monitoring of all primary health care services that affect residents of the state." Central to this reform is the integration of primary health care (PHC) governance and management, popularly called primary health care under one roof. Another reform, piloting results-based financing, has been implemented since 2011 in three states under the Nigeria State Health Investment Project. This study assesses the implementation of the Primary Health Care Under One Roof (PHCUOR) policy as part of the broader PHC reforms, with a specific focus on how this policy has been strengthened through the Nigeria State Health Investment Project (NSHIP) in Adamawa, Nasarawa, and Ondo states, documenting the evolution of SPHCDB and PHC service delivery, with a focus on management, accountability, and incentives. The study shows that, in the above-mentioned states, significant milestones were achieved in the establishment of the SPHCDB, the strengthening of PHC systems, the improvement of accountability linkages, and an increase in service utilization. The authors therefore argue that integrated PHC systems through SPHCDBs, as enshrined in the PHCUOR guidelines, are a panacea for effective provision of primary health care and a potential game changer for health outcomes, especially when reinforced with a results-based financing approach.

Salmonella Bacteremia Among Children in Central and Northwest Nigeria, 2008-2015.

BACKGROUND: Etiologic agents of childhood bacteremia remain poorly defined in Nigeria. The absence of such data promotes indiscriminate use of antibiotics and delays implementation of appropriate preventive strategies. METHODS: We established diagnostic laboratories for bacteremia surveillance at regional sites in central and northwest Nigeria. Acutely ill children aged <5 years with clinically suspected bacteremia were evaluated at rural and urban clinical facilities in the Federal Capital Territory, central region and in Kano, northwest Nigeria. Blood was cultured using the automated Bactec incubator system. RESULTS: Between September 2008 and April 2015, we screened 10,133 children. Clinically significant bacteremia was detected in 609 of 4051 (15%) in the northwest and 457 of 6082 (7.5%) in the central region. Across both regions, Salmonella species account for 24%-59.8% of bacteremias and are the commonest cause of childhood bacteremia, with a predominance of Salmonella enterica serovar Typhi. The prevalence of resistance to ampicillin, chloramphenicol, and cotrimoxazole was 38.11%, with regional differences in susceptibility to different antibiotics but high prevalence of resistance to readily available oral antibiotics. CONCLUSIONS: Salmonella Typhi is the leading cause of childhood bacteremia in central Nigeria. Expanded surveillance is planned to define the dynamics of transmission. The high prevalence of multidrug-resistant strains calls for improvement in environmental sanitation in the long term and vaccination in the short term.

How decentralisation influences the retention of primary health care workers in rural Nigeria.

BACKGROUND: In Nigeria, the shortage of health workers is worst at the primary health care (PHC) level, especially in rural communities. And the responsibility for PHC - usually the only form of formal health service available in rural communities - is shared among the three tiers of government (federal, state, and local governments). In addition, the responsibility for community engagement in PHC is delegated to community health committees. OBJECTIVE: This study examines how the decentralisation of health system governance influences retention of health workers in rural communities in Nigeria from the perspective of health managers, health workers, and people living in rural communities. DESIGN: The study adopted a qualitative approach, and data were collected using semi-structured in-depth interviews and focus group discussions. The multi-stakeholder data were analysed for themes related to health system decentralisation. RESULTS: The results showed that decentralisation influences the retention of rural health workers in two ways: 1) The salary of PHC workers is often delayed and irregular as a result of delays in transfer of funds from the national to sub-national governments and because one tier of government can blame failure on another tier of government. Further, the primary responsibility for PHC is often left to the weakest tier of government (local governments). And the result is that rural PHC workers are attracted to working at levels of care where salaries are higher and more regular - in secondary care (run by state governments) and tertiary care (run by the federal government), which are also usually in urban areas. 2) Through community health committees, rural communities influence the retention of health workers by working to increase the uptake of PHC services. Community efforts to retain health workers also include providing social, financial, and accommodation support to health workers. To encourage health workers to stay, communities also take the initiative to co-finance and co-manage PHC services in order to ensure that PHC facilities are functional. CONCLUSIONS: In Nigeria and other low- and middle-income countries with decentralised health systems, intervention to increase the retention of health workers in rural communities should seek to reform and strengthen governance mechanisms, using both top-down and bottom-up strategies to improve the remuneration and support for health workers in rural communities.
