Adherence to medical follow-up recommendations reduces hospital admissions: Evidence from diabetic patients in France.

The aim of this study was to document the extent to which diabetic patients who adhered to required medical follow-ups in France experienced reduced hospital admissions over time. The main assumption was that enhanced monitoring and follow-up of diabetic patients in the primary care setting could be a substitute for hospital use. Using longitudinal claim data of diabetic patients between 2010 and 2015 from MGEN, a leading mutuelle insurance company in France, we estimated a dynamic logit model with lagged measures of the quality of adherence to eight medical follow-up recommendations. This model allowed us to disentangle follow-up care in hospitals from other forms of inpatient care that could occur simultaneously. We found that a higher adherence to medical guidance is associated with a lower probability of hospitalization and that the take-up of each of the eight recommendations may help reduce the rates of hospital admission. The reasons for the variation in patient adherence and implications for health policy are discussed.
