Overcrowding in Emergency Departments is often considered as an outcome of insufficient access to hospital beds or primary care, therefore a potential lack of health resources. We sought to describe the quantitative evolution of health resources in the French health care system, in comparison with demographic and epidemiologic parameters that reflect health needs. Overall, in the last decade, parameters of capacity and human resources stagnated while activity and spending increased jointly, stimulated by ageing of the population and chronic diseases mostly. Nevertheless, recent official previsions have again recommended to proceed with hospital bed reduction until 2030. This has led to a dangerous saturation of emergency care and to the ongoing systemic health crisis. This situation will require ambitious health resources reinforcement plans in both hospital and primary care. Furthermore, ageing of the population and chronic diseases must lead society to deliberate on the fundamental goals and funding of our health care system.
