Influence of a quality improvement intervention on rehabilitation outcomes of children (6-24 months) with acute malnutrition: a retrospective study in rural Angola

Background Defaulting is the most frequent cause of Community Management of Acute Malnutrition (CMAM) program failure. Lack of community sensitization, financial/opportunity costs and low quality of care have been recognized as the main driving factors for default in malnutrition programs. The present study aimed to evaluate if a logistic reorganization (generic outpatient department, OPD vs dedicated clinic, NRU) and a change in management (dedicated vs non dedicated staff) of the follow-up of children between 6 and 24 months of age with acute malnutrition, can reduce the default, relapse and readmission rate and increase the recovery rate. Methods Retrospective observational study on the impact of quality improvement interventions on rehabilitation outcomes of children (6-24 months) with acute malnutrition, admitted at the Catholic Mission Hospital of Chiulo (Angola) from January 2018 to February 2020. Main outcome measures were recovery rate, the default rate, the relapse rate, and the readmission rate. Results The intervention was associated with a decrease in the default rate from 89 to 76% (p = 0.02). Recovery rate was 69% in OPD and 88% in NRU (p = 0.25). Relapse rate was nil. Conclusions The present study supports the hypothesis that an improvement in quality of care can positively influence the rehabilitation outcomes of malnourished children. Further studies are needed to identify children at risk of low adherence to follow-up visits to increase the effectiveness of rehabilitation programs.
