The sorting effect in healthcare access: Those left behind

Résumé 0

Many governments have sought to enhance patient choice in hospital by intensifying competitive pressure on hospital administrations that results in an improvement in efficiency, quality, and innovation. However, there is mixed evidence on whether patients travel past their local hospitals to seek better quality care and whether higherincome patients are those most sensitive to respond to competitive pressures. Using detailed data from 17 million inpatient stays admitted in France during 2019, this paper explores the attributes of hospital ownership as determinants of patients' choice for healthcare. We found that, in general, patients travel for their care, with just one-quarter of them going to the nearest hospital. In fact, the most vulnerable patients (i.e., those socioeconomically deprived, and very aged) are mostly treated in local public hospitals with the lowest quality service level, and with large variability in quality as well, while those with less socioeconomic deprivation seek care at higher-quality for-profit hospitals. Our counterfactual simulations show that admission to university hospitals attenuates existing inequalities. However, whether it delays the healthcare access sought by this population remains an open question.
