Analgesic drug use associated with statin prescription--a cross-sectional study in primary care settings.

ABSTRACT

BACKGROUND: To investigate whether features of muscular complaints (MC) differ between receivers of a statin prescription and non-receivers. To analyze the relationship between analgesics prescription, statin prescription and/or musculoskeletal disorders. METHODS: Cross-sectional study. Consecutive patients in offices of family practitioners were interviewed using a standardized questionnaire. Target variables Rates of features of MC in patients with or without a statin prescription and rates of analgesic drug prescription in patients with or without statin prescription and/or musculoskeletal disorders. Odds ratios (adjusted for age, sex, and socio-economic status) were calculated using logistic regression analysis. RESULTS: 1135 patients in 26 general practitioners' offices were asked to participate, and 1031 patients agreed. Features of MC did not differ between the two groups of patients. Analgesic prescription was found to be associated with statin prescription in patients without musculoskeletal disorders (OR 2.2, CI 1.1-4.7 without statin, OR 2.5, CI 0.9-6.9 with statin) and particularly in those with musculoskeletal disorders (OR 5.2, CI 2.9-9.3 without statin, OR 9.3, CI 4.5-19.1 with statin). CONCLUSIONS: Analgesic prescriptions are probably positively associated with statin prescription. Assuming that analgesics attenuate MC, an even stronger association between MC and statin use seems likely. The results generate the hypothesis that statin use contributes to analgesic use in primary care patients.
