Adherence to integrated management of childhood illness (IMCI) guidelines by community health workers in Kano State, Nigeria through use of a clinical decision support (CDS) platform.

BACKGROUND: The World Health Organization (WHO) Integrated Management of Childhood Illness (IMCI) guidelines established in 1992 to decrease preventable under-five child morbidity and mortality, was adopted by Nigeria in 1997. Over 20 years later, while under-five child mortality remains high, less than 25% of first level facilities have trained 60% of community health workers (CHW) who care for sick children with IMCI. This study investigated the impact in CHWs overall adherence to IMCI guidelines, particularly for critical danger signs, as well as usability and feasible following the implementation of THINKMD's IMCI-based digital clinical decision support (CDS) platform. METHODS: Adherence to IMCI guidelines was assessed by observational and digital data acquisition of key IMCI clinical data points by 28 CHWs, prior, during, and post CDS platform implementation. Change in IMCI adherence was determined for individual CHW and for the cohort by analyzing the number of IMCI data points acquired by each CHW per clinical evaluation. Consistency of adherence was also calculated by averaging the percentage of total evaluations each data point was observed. Usability and acceptability surveys were administered following use of the CDS platform. RESULTS: THINKMD CDS platform implementation notably enhanced the CHWs' ability to capture key IMCI clinical data elements. We observed a significant increase in the mean percentage of data points captured between the baseline period and during the CDS technology implementation (T-test, t = -31.399, p < 0.016, Holm-Bonferroni correction, two-sided), with the mean values going from 30.7% to 72.4%. Notably, even after the completion of the technology implementation phase, the mean percentage of IMCI elements captured by CHWs remained significantly elevated compared to the baseline, with a 26.72 percentage point increase (from 30.7% to 57.4%, T-test, t = -15.779, p < 0.05, Holm-Bonferroni correction, two-sided). Usability and feasibility of the platform was high. CHWs reported that the CDS platform was easy to learn and use (93%) and enabled them to identify sick children (100%). CONCLUSION: These results demonstrate that utilization of a digital clinical decision support tool such as THINKMD's IMCI based CDS platform can significantly increase CHW adherence to IMCI guidelines over paper-based utilization, increase clinical quality and capacity, and improve identification of key danger signs for under-five children while being highly accepted and adopted.

Effect of Vaccine Direct Delivery (VDD) on vaccine stockouts and number of vaccinations: Case study from Bauchi State, Nigeria.

OBJECTIVE: Vaccine stockouts are prevalent in Africa. Despite the importance of this as a barrier to universal vaccination coverage, rigorous studies looking at ways to reduce vaccine stockouts have been limited. We causally evaluated the effect of Vaccine Direct Delivery (VDD), an intervention to ensure the vaccine stock availability at health facilities, on the reduction of stockouts in Bauchi state, Nigeria. METHODS: Employing the interrupted time-series method, we evaluated the change in the occurrence of vaccine stockouts before and after the introduction of VDD in July 2015. We used health facility level data from January 2013 to December 2018 among 175 facilities in Bauchi state, collected through the District Health Information Software 2 (DHIS2) for monthly information on stockouts and stock balances in all the health facilities in Nigeria. Data were analyzed using Stata 15 SE. To validate the causal relationship between VDD and vaccine stockouts, we conducted two sets of robustness checks. First, we evaluated the effect of VDD on the stockouts of other commodities. Second, we compared the trend of the prevalence of vaccine stockouts among health facilities between Bauchi state where VDD was introduced and another state (Adamawa state) where VDD was never introduced. RESULTS: After the introduction of VDD, vaccine stockouts in Bauchi state decreased by 9 percentage points on average, and they have been decreasing monthly by 0.4 percentage points more than pre-VDD. In Adamawa state, where VDD was never introduced, the prevalence of vaccine stockouts did not change over time. In Bauchi state after VDD introduction, the stock balances of target vaccines all increased, and the number of vaccinations carried out increased in neighboring health facilities. CONCLUSIONS: VDD intervention resulted in a significant reduction of vaccine stockouts as well as in an increase in the number of vaccinations performed. However, we should consider how to improve the system to provide vaccination service to the population in a sustainable way.
