Dispensary record group VIII for patients with sarcoidosis was introduced in Moscow in 1994 and a center based on the Moscow Research Production Center?? was set up to diagnose and treat such patients. In addition to advisory work, the sarcoidosis center performs organizational and methodological functions. A scheme of subgroup (A, B, and C) distribution of Group III patients by the activity and pattern of sarcoidosis has been developed to have unique follow-up methods. The diagnosis made in the patients and their dispensary registration, the efficiency of treatment, and their movement by subgroups are checked up. This system of a center-dispensary interaction revealed a dynamics in sarcoidosis incidence and prevalence in the city in 1994-1997. Evidence is provided for that it is expedient and timely to organize a follow-up of patients with sarcoidosis particularly when the share of paid medical services is increasing.
