Objective: To evaluate the spectrum of rheumatic disease in a tertiary level hospital in Bangladesh. Materials and Methods: This cross-sectional study was carried out at the Physical Medicine and Rehabilitation department of the DMCH for six months. The study sought to enroll patients who had musculoskeletal problems or systemic symptoms that would indicate rheumatic illness. After meeting the requirements, patients were accepted. Each respondent provided written informed consent, and those who refused to engage in the study or undertake additional research were not included. By conducting a face-to-face interview with the respondents and utilizing a pre-tested semi-structured questionnaire, information about the respondents' socio-demographic characteristics, disease duration, clinical symptoms and signs, and investigations report was gathered.
