Abstract
BACKGROUND: Poor access and utilisation of health care services remains a big challenge in rural communities in low to middle income countries leading to high prevalence of preventable childhood illnesses and death. Many community mobilisation models have been employed to address this. However, scientific evidence remain scanty on the long-term effects of such models to inform policy-makers on how to reduce preventable child morbidity and mortality and to provide guidance on what is pragmatic. The purpose of this study was to determine the long-term effects of the Integrated Care Model (ICM) on child morbidity and mortality in Zimbabwe.
 
 METHODS: This was a pragmatic trial that used a quasi-experimental design. The study used population based sampling to enrol villages into either intervention sites or control sites from two health centres in Murewa District. Target sampling was used to enrol children aged 0-48 months into the study. A total of 1380 children were enrolled and followed up prospectively for a period of 18 months. The disease condition that were being tracked were pneumonia, diarrhoea, fever and Malaria.
 
 RESULTS: We performed negative binomial logistic regression to determine the long-term effects of the intervention on child morbidity, adjusting for the number of under-fives in each village/cluster, village size, distance to the clinic and number of under-fives in each cluster. Overall, the intervention reduce the risk of general child morbidity by 83% [RR=0.17, 95% CI (0.14-0.23)]. The intervention reduced risk of incidence of pneumonia by 79% [RR=0.21, 95% CI (0.10-0.45)], risk of incidence of diarrhoea by 80% [RR=0.20 95% CI (0.15-0.29)], fever by 91%[RR=0.09, 95% CI (0.04-0.22)] and malaria by 73%[RR=0.27, 95% CI (0.14-0.51)].The incidence rate of childhood severe illnesses was reduced by 79%[RR=0.24, 95% CI (0.11-0.40)] through the intervention. 
 
 CONCLUSION: This study sought to determine the long term effects of the Integrated Care Model on Child Morbidity in Murewa district, Zimbabwe. Study results revealed that indeed the ICM had a statistically significant impact on child morbidity in the long-term. Countries in low resource settings can benefit from the use of such a low-cost high impact model to reduce not only child morbidity and mortality, but also to address maternal health challenges.

Summary
There is currently much controversy over the effectiveness of the community mobilisation models in reducing child morbidity in the long-term. There is still limited evidence about the effectiveness of integrated community-based approaches in reducing child morbidity. Poor access and utilisation of health care services remains a big challenge in rural communities in low to middle income countries leading to high prevalence of preventable childhood illnesses and death. Scientific evidence remain scanty on the long-term effects of such models to inform policy-makers on how to reduce preventable child morbidity and mortality and to provide guidance on what is pragmatic.
