Introduction. The prevalence of frailty among the rheumatologic population ranges from 23 to 60% cases. As rheumatic diseases are characterized by chronic inflammation, so frailty is an emerging concept in the identification of individuals, vulnerable to outcomes. Material and methods. The study included 23 patients hospitalized with rheumatic diseases between January and December 2022 with SLE, RA, PR, Takayasu, SS, PsA and OA. The mean age was 60.4±1.65 (19-81) y.o, 19 (82.6%) women. Frailty was auto-assessed by the Edmonton score. Results. Different degrees of frailty were identified in 9 (39.1%), women: men ratio 2:1, the average age in frail group- 57.5±2.53 y.o, Cognitive assessment by "imaginary clock" test detected minor mistakes in 22.2% and serious - 77.8% cases. Addressability noted that 55.6% required medical assistance 2-4 times/year and 44% -5-8 times/year. Self-reported health status data was „acceptable” in 66.7% and „low” in 33.3 %, while „good” health hadn’t been reported. Patients needed help at least for 2-4 activities - 55.6% and 33.3% with 5-8 daily activities. Permanent social support needed 2 (22.2%), occasional -7 (77.8%) cases. Drug administration of 5 and more drugs was in 88.8%, about 1/3 sometimes skip it. Loss of weight was reported by 2 (22.2%), the decrease of physical activity- 6 (66.7%), incontinence – 4 (44.4%), sleep five or less hours in 5 (55.6%) frail respondents. Feeling of sadness was noted in 66.7% cases. "Getting up and walking" test identified slow walk (≥ 10s) in 77.8% patients. Conclusion. Frailty syndrome is common in rheumatic diseases estimated in our study group in 39.1% cases, affecting the four main domains: cognitive, clinical, physical and social.
