Effectiveness of antimalarial interventions in Nigeria: Evidence from facility-level longitudinal data.

ABSTRACT:

Objective

To evaluate the effectiveness of a program of antimalarial interventions implemented in 2010-2013 in Niger State, Nigeria.

Data sources

Utilization reports from 99 intervention and 51 non-intervention health facilities from the Niger State Malaria Elimination Program, supplemented by data on facility-level characteristics from the Niger State Primary Health Care Development Agency and Local Government Malaria Control units.

Study design

Estimated with mixed-effects negative binomial modeling, a difference-in-differences method was used to quantify the impact of the program on the number of febrile illness cases and confirmed malaria cases. Potential confounding factors, non-stationarity, seasonality, and autocorrelation were explicitly accounted for.

Data extraction methods

Data were retrieved from hard copies of utilization reports and manually inputted to create a panel of 5550 facility-month observations.

Principal findings

The program was implemented in two phases. The first phase (August 2010-June 2012) involved the provision of free artemisinin-based combination therapies, long-lasting insecticidal nets, and intermittent preventive treatments. In the second phase (July 2012-March 2013), the program introduced an additional intervention: free parasite-based rapid diagnostic tests. Compared to the pre-intervention period, the average number of monthly febrile illness and malaria cases increased by 20.876 (P < 0.01) and 22.835 (P < 0.01) in the first phase, and by 19.007 (P < 0.05) and 19.681 (P < 0.05) in the second phase, respectively. The results are consistent across different evaluation methods.

Conclusions

This study suggests that user-fee removal leads to increased utilization of antimalarial services. It motivates future studies to cautiously select their investigative methods.

Project description:BackgroundUnmet need for postpartum contraception is high. Integration of family planning with routine child immunization services may help to satisfy unmet need. However, evidence about the determinants and effects of integration has been inconsistent, and more evidence is required to ascertain whether and how to invest in integration. In this study, facility-level family planning and immunization integration index scores are used to: (1) determine whether integration changes over time and (2) identify whether facility-level characteristics, including exposure to the Nigerian Urban Reproductive Health Initiative (NURHI), are associated with integration across facilities in six urban areas of Nigeria.MethodsThis study utilizes health facility data collected at baseline (n = 400) and endline (n = 385) for the NURHI impact evaluation. Difference-in-differences models estimate the associations between facility-level characteristics, including exposure to NURHI, and Provider and Facility Integration Index scores. The two outcome measures, Provider and Facility Integration Index scores, reflect attributes that support integrated service delivery. These indexes, which range from 0 (low) to 10 (high), were constructed using principal component analysis. Scores were calculated for each facility. Independent variables are (1) time period, (2) whether the facility received the NURHI intervention, and (3) additional facility-level characteristics.ResultsWithin intervention facilities, mean Provider Integration Index scores were 6.46 at baseline and 6.79 at endline; mean Facility Integration Index scores were 7.16 (baseline) and 7.36 (endline). Within non-intervention facilities, mean Provider Integration Index scores were 5.01 at baseline and 6.25 at endline; mean Facility Integration Index scores were 5.83 (baseline) and 6.12 (endline). Provider Integration Index scores increased significantly (p = 0.00) among non-intervention facilities. Facility Integration Index scores did not increase significantly in either group. Results identify facility-level characteristics associated with higher levels of integration, including smaller family planning client load, family planning training among providers, and public facility ownership. Exposure to NURHI was not associated with integration index scores.ConclusionPrograms aiming to increase integration of family planning and immunization services should monitor and provide targeted support for the implementation of a well-defined integration strategy that considers the influence of facility characteristics and concurrent initiatives.

Project description:Most of the maternal and newborn deaths occur at birth or within 24 hours of birth. Therefore, essential lifesaving interventions need to be delivered at basic or comprehensive emergency obstetric care facilities. Facilities provide complex interventions including advice on referrals, post discharge care, long-term management of chronic conditions along with staff training, managerial and administrative support to other facilities. This paper reviews the effectiveness of facility level inputs for improving maternal and newborn health outcomes. We considered all available systematic reviews published before May 2013 on the pre-defined facility level interventions and included 32 systematic reviews. Findings suggest that additional social support during pregnancy and labour significantly decreased the risk of antenatal hospital admission, intrapartum analgesia, dissatisfaction, labour duration, cesarean delivery and instrumental vaginal birth. However, it did not have any impact on pregnancy outcomes. Continued midwifery care from early pregnancy to postpartum period was associated with reduced medical procedures during labour and shorter length of stay. Facility based stress training and management interventions to maintain well performing and motivated workforce, significantly reduced job stress and improved job satisfaction while the interventions tailored to address identified barriers to change improved the desired practice. We found limited and inconclusive evidence for the impacts of physical environment, exit interviews and organizational culture modifications. At the facility level, specialized midwifery teams and social support during pregnancy and labour have demonstrated conclusive benefits in improving maternal newborn health outcomes. However, the generalizability of these findings is limited to high income countries. Future programs in resource limited settings should utilize these findings to implement relevant interventions tailored to their needs.

Project description:BackgroundA recent systematic review suggested that drug registrations and onsite quality inspections may be effective in reducing the prevalence of counterfeit and substandard drugs. However, simply replicating the most effective interventions is problematic, as it denotes implementing the intervention without further adaptation.ObjectiveThe aim was to systematically review the evidence beyond effectiveness for systems-level interventions to combat or prevent drug counterfeiting.MethodsWe conducted an extensive search, including an electronic search of 14 databases. We included studies examining the efficiency, feasibility, reliability, and economic outcomes of the interventions, as well as barriers and facilitators to their implementation. Two reviewers selected eligible studies and abstracted data in duplicate and independently. We synthesized the results narratively, stratified by type of intervention.ResultsOf 10,220 captured citations, 19 met our inclusion criteria. The findings suggest that the following may strengthen regulatory measures (e.g., registration): minimizing drug diversion, enhancing lines of communications, ensuring feedback on drug quality, and promoting strict licensing criteria. There is evidence that onsite quality surveillance and inspection systems may be efficient and cost-effective for preliminary testing of large samples of drugs. Laws and legislation need to be specific to counterfeit drugs, include firm penalties, address online purchasing of drugs, and be complemented by education of judges and lawyers. Public awareness and education should rely on multiple platforms and comprehensive and dedicated content. While product authentication technologies may be efficient and reliable in detecting counterfeit drugs in the supply chain, they require a strong information system infrastructure. As for pharmacovigilance systems, it is critical to tackle the issue of underreporting, to enhance their chances of success.ConclusionSeveral factors are critical to the successful design and implementation of systems-level interventions to combat or prevent drug counterfeiting. Policymakers need to take these into consideration to ensure success of these interventions.

Project description:BackgroundNational programs are often developed with little consideration to the sub-national local factors that might affect program success. These factors include political support, capacity for implementation of program and variation in malnutrition indices being tackled. State context factors are evident in the distribution of malnutrition (e.g. high prevalence or gap among Local Government Areas), in the implementation of nutrition-sensitive interventions (e.g. access to early childhood education) and in the political economic context (e.g. presence of external funding agencies). Context is shaped by the economy, population, religion, and poverty, which impact everyday lives. Considering these contexts, a roadmap was developed and validated. The aim of this paper is to report expert review and stakeholder validation to determine feasibility of the developed contextualised roadmap for two Nigerian states.MethodsA validation tool was developed and reviewed using three experts. The content review occurred in two rounds to obtain recommendation and revisions of the developed roadmap and the validation tool. A pilot test of the roadmap and validation tool was done using two stakeholders in South Africa. The roadmap and the validation tool were then sent to the stakeholders and potential end-users in Nigeria using electronic media. Two research assistants were also engaged to deliver and collect hard copies to those who preferred it.ResultsOf the ten stakeholders invited, nine responded. All participants showed an adequate understanding of the roadmap as evidenced by the scores given. Responses regarding the translation of the roadmap to implementation varied. The majority (86,6%) either strongly agreed or agreed that the actions were translatable (43.0 and 43.6% respectively).ConclusionsThe final roadmap comprises of actions that are appropriate for the state's context. It is recommended that stakeholders or end-users of any programme must be involved in the validation of such contextual programmes to improve chances of success.
