Containment Impact on Primary Care & Adverse Events Unrelated to COVID-19 in Older Patients and/or With Chronic Diseases

In 2017, 10.7 million people affiliated to the general health insurance scheme benefited from the "Long-term condition" scheme, i.e. 17% of insured patients. Most of these patients suffer from chronic diseases requiring regular medical and paramedical follow-up. During the first containment period of the SARS-CoV-2 epidemic, the French government's messages were to call the Urgent Medical Assistance Service (15) and not to go directly to the general practitioner (GP), favouring teleconsultations. Other countries have adopted the same strategy. Mortality rates due to SARS-CoV-2 infection were higher in elderly patients and/or those with co-morbidities, particularly heart failure, hypertension, respiratory failure and diabetes. The elderly and patients with chronic cardiometabolic and respiratory diseases should therefore be particularly protected during the epidemic. However, these populations also need close monitoring to avoid acute decompensation of their chronic diseases or loss of autonomy. However, during the first containment, general practitioners and other medical and paramedical ambulatory health professionals perceived a notable decrease in their daily activity, including for their chronic and/or elderly patients who may not have called for a visit, consultation and/or access to telemedicine. "Public Health France" also reported a decrease in consultations with GPs at the beginning of the lockdown, a decrease in the number of emergency room visits and hospitalizations for cardio and neurovascular diseases. The investigators hypothesise that under-attendance of primary care services during the epidemic is associated with excess mortality and morbidity unrelated to COVID-19. The main objective is to assess non-COVID-19 related overmortality during the containment period and 12 months after the start of containment, in a population of elderly and/or chronically ill patients in France. The overmortality will be assessed globally and according to individual an
