Effectiveness of four interventions in improving community health workers' performance in western Kenya: a quasi-experimental difference-in-differences study using a longitudinal data.

BACKGROUND: Community health workers (CHWs) are up-front health workers delivering the most effective life-saving health services to communities. They are the key driver to achieve Universal Health Coverage. However, maintaining CHWs' performance is one of the challenges in sustaining their effectiveness. This article assessed the effectiveness of the four interventions and their combinations on the CHWs' performance in terms of health knowledge, job satisfaction, and household coverage. METHODS: We used the longitudinal survey data collected in western Kenya. Our study participants were the representative of all CHWs working in the four districts, Kenya. The four types of interventions were composed of a basic core intervention (i.e., refresher training with/without defaulter tracing) and three supplementary interventions (i.e., provision of a bicycle, frequent supportive supervision, and financial incentives). We performed the three fixed-effect models to assess the effectiveness of the four interventions and their combinations on the three performance indicators. RESULTS: Three single and combination interventions significantly increased CHWs' health knowledge: refresher training only [Coef.: 48.43, 95% CI: 42.09-54.76, P < 0.001]; refresher training plus defaulter-tracing [Coef.: 38.80, 95% CI: 32.71-44.90, P < 0.001]; combination of refresher training plus defaulter-tracing and frequent supervision [Coef.: 17.02, 95% CI: 7.90-26.15, P < 0.001]. Financial support was the only intervention that significantly increased job satisfaction among CHWs [Coef.: 4.97, 95% CI: 0.20-9.75, P = 0.041]. There was no single intervention that significantly increased household coverage. Yet, the combinations of the interventions significantly increased household coverage. CONCLUSIONS: There was no single intervention to improve all the aspects of CHWs' performance. The refresher training significantly improved their health knowledge, while financial incentive enhanced the level of their job satisfaction. The combinations of regular refresher training and other intervention(s) are the recommended as the effective interventions in improving and further sustaining CHWs' performance.

Determinants of health facility utilization for childbirth in rural western Kenya: cross-sectional study.

BACKGROUND: Skilled attendance at delivery is recognized as one of the most important factors in preventing maternal death. However, more than 50% of births in Kenya still occur in non-institutional locations supported by family members and/or traditional birth attendants (TBAs). To improve this situation, a study of the determinants of facility delivery, including individual, family and community factors, was necessary to consider effective intervention in Kenya. METHODS: This study was conducted to identify the factors which influence the place of delivery in rural western Kenya, and to recommend ways to improve women's access to skilled attendants at delivery. A community-based cross-sectional survey was carried out from August to September 2011 in all 64 sub-locations which were covered by community health workers (CHWs). An interviewer-administered questionnaire on seventeen comprehensive variables was administered to 2,560 women who had children aged 12-24 months. RESULTS: The response rate was 79% (n = 2,026). Of the respondents, 48% of births occurred in a health facility and 52% in a non-institutional location. The significant determinants of facility delivery examined using multivariate analysis were: maternal education level, maternal health knowledge, ANC visits, birth interval, economic status of household, number of household members, household sanitation practices and traveling time to nearest health facility. CONCLUSIONS: The results suggest that the involvement of TBAs to promote facility delivery is still one of the most important strategies. Strengthening CHWs' performance by focusing on a limited number of topics and clear management guidance might also be an effective intervention. Stressing the importance of regular attendance at ANC (at least four times) would be effective in enhancing motivation for a facility delivery. Based on our findings, those actions to improve the facility delivery rate should focus more on pregnant women who have a low education level, poor health knowledge and short pregnancy spacing. In addition, women with low economic status, a large number of family members and a long distance to travel to a health facility should also be targeted by further interventions.
