Objective. Fibromyalgia (FM) is a central pain syndrome characterised by widespread pain, fatigue, unrefreshing sleep, memory impairment and cognitive changes, predominantly in women, and is a cause for disability and frequent sick leave. So far, no assessment has been made of the use of the American College of Rheumatology (ACR) 2010 questionnaire in the fitness for work (FFW) assessment of FM patients. To assess the correlation between the severity of FM as measured by the ACR questionnaire and other parameters and FFW. Methods. We conducted a retrospective cross-sectional study involving women with FM who had their FFW assessed at an occupational health clinic between 2014-2018. The ACR questionnaire was completed during the medical assessment. Results. We examined 60 files of women, mean age 48.8 years. Absolute loss of working capacity (ALWC) was calculated in relation to a standard 8-hour workday, while relative loss of working capacity (RLWC) was based on the patient’s actual appointment percentage before the examination. The average ALWC determined by the occupational physicians was 59% ± 33%. Age group correlated significantly with ALWC (correlation coefficient = 0.03, p<0.05). The Part 2b symptoms (0-41) also correlated significantly with ALWC (mean ± SD 21.8±5.6, correlation coefficient = 0.23, p<0.05). Medical treatment correlated significantly with RLWC (correlation coefficient = 0.02, p<0.05). The rate of disability was high compared to what was reported in other studies. The correlation between different parts of the ACR questionnaire and disability demonstrated that symptom severity is a predictor of loss of working capacity. Conclusion. When performing a FFW assessment of FM patients, physicians may use the ACR questionnaire, since FFW correlates with its score. We assume that patients who experience more pain visit their physicians more often and consume more analgesics.
