BACKGROUND: In Italy, where all mental hospitals have been gradually phased out since 1978, psychiatric patients requiring long-term care are being treated in non-hospital residential facilities (NHRFs). However, detailed data on these facilities are sparse. AIMS: The Progetto Residenze (PROGRES) residential care project is a three-phase study, the first phase of which aims to survey the main characteristics of all Italian NHRFs. METHOD: Structured interviews were conducted with the manager of each NHRF. RESULTS: On 31 May 2000 there were 1370 NHRFs with 17 138 beds; an average of 12.5 beds each and a rate of 2.98 beds per 10 000 inhabitants. Residential provision varied ten-fold between regions and discharge rates were very low. Most had 24-hour staffing with 1.42 patients per full-time worker. CONCLUSIONS: There is marked variability in the provision of residential places between different regions; discharge rates are generally low.
