Description of the population covered by the data source in the catchment area whose data are not collected (e.g., people who are registered only for private care)

The population covered by the ReS database is composed only by people of whom data are collected in the administrative databases. Namely, each time a patient receives a healthcare service reimbursed by the Italian National Healthcare Service (SSN), the patient is registered in the related administrative database that is forwarded to ReS by the local/regional Health Authority with whom ReS has signed the specific agreement. Patients are not registered when they pay for the healthcare service (i.e., drugs, hospitalizations, inpatient/outpatient specialist care) which is only provided as out-of-pocket. Namely, this happens when the service is not reimbursed by the SSN (e.g., off label drug, OTC drug, services performed in private facilities or not affiliated with the SSN...) or when the patient does not want to be cared by the SSN.
