The aim of the study. To estimate the rate of admission to hospital the patients with idiopathic inflammatory myopathies (IIM) in moldovian cohort. Materials and methods: We performed a cross-sectional study from January − December 2016. The patients included in the study fulfilled the Bohan and Peter criteria for IIM. Results. Thirty-four patients were enrolled in the study, of which resulted in 27 hospitalizations. The mean age at diagnosis was 44.6±14.9 years versus 52.9±12.5 years at the time of hospitalization. Twelve (35.2%) patients were not hospitalized during last 12 months. The most common reasons for admission to hospital were recurrence of the disease − 10 (29.4%) patients, myalgia − 6 (17.6%) patients and complications (osteoporosis, avascular necrosis) in 5 (14.7%) patients. The less common causes for hospitalizations were infection and pain, both in 3 (8.8%) patients. The mean hospitalization period was 7.9 (range 414) days. We determined the annual rate of hospitalizations for IIM was 0.79 patients per year. The hospitalization rate in patients with disease duration less than 24 months was 0.81 versus 0.7 per year in patients with disease more than 2 years. During study period there was no death. Conclusion. In moldovian cohort of patients with IIM the rate of hospitalization was 0.79 patients per year, flares being the most frequent reason..
