The Romanian authorities are the main recipients of requests regarding doctors through the IMI system, receiving around 16.5% of all requests on average per month. The Ministry of Health responds to 70% of requests, taking around 3 weeks on average to respond, while the Romanian College of Physicians responds to 5% of requests. Some difficulties encountered include the large volume of requests, the need to contact authorities not registered in IMI for additional information, and limited staff and resources to thoroughly research and respond to all requests in a timely manner.
