Competition in French hospital: Does it impact the patient management in healthcare?

Summary We explore the competition impact on patient management in healthcare (length of stay and technical procedure's probability to be performed) by difference-indifference , exploiting time variations in the intensity of local competition caused by the French pro-competition reform (2004-2008). Models are estimated with hospital fixed effects to take into account hospital unobserved heterogeneity. We use an exhaustive dataset of in-hospital patients over 35 admitted for a heart attack. We consider the period before the reform from 2001 to 2003 and a period after the reform from 2009 to 2011. Before the reform, there were two types of reimbursement systems. Hospitals from private sector, were paid by fee-for-service. Hospitals from public sector were paid by global budget. They had no current activity's link, and a weak competition incentive. After the DRG-based payment reform, all hospitals compete with each other to attract patients. We find the reform a sizeable positive competition effect on high-technical procedure for the private sector as well as a negative competition effect on the length of stay for public hospitals. However, the overall local competition effect of the reform explained a very marginal part of the explanatory power of the model. Actually, this period is characterised by two contradictory components: a competition effect of the reform and in-patients who are more concentrated. Results suggest that if competition impacted management patient's change, it is through a global competition included in a global trend much more than a local competitive aspect of the reform.
