OBJECTIVE: To determine the prevalence and characteristics of inappropriate prescribing of drugs (IP) in patients >65 years-old evaluated by a primary care team (PCT), using the STOPP-START criteria. MATERIAL AND METHOD: Cross-sectional sample of patients older than 65 years-old with active clinical history in 2010, and who were attended in 13 urban clinics (systematic random sampling, expected IP prevalence of 40%, precision: 5% confidence level: 95%). Requirement was reviewed clinical histories in 2010, using the STOPP-START criteria. RESULTS: A total of 363 patients were selected (56.7% women), mean age 75.2 years (SD: 7.02). The most frequent diseases were cardiovascular (76.9%) and osteoarticular (57.6%) diseases, and the average number of prescription drugs was 4.9 (SD: 3.32). IP was detected in 170 patients (46.8%; 95% CI: 41.7-52.0%), 42% in men (95% CI: 34.3-49.8%) and 46.6% in women (95% CI: 39.8-53.4%), with no differences between sexes (P=.386), with a higher prevalence if polypharmacy or comorbidity were present (P<.001). The STOPP criteria were met in 131 patients (36.1%; 95% CI: 31.1-41.0%), and START criteria in 73 (20.1%; 95% CI: 16-24.2%), with no difference between sexes (P=.623 for STOPP, and P=.678 for START). The most frequent STOPP criteria were observed in the musculoskeletal system (50 patients, 38.2%; 95% CI: 29.8-46.5%) and START endocrinology indicators (38 patients, 52.1%; 95% CI: 40.0-63.9%). CONCLUSIONS: The STOPP-START tool detected and systematised IP in a high percentage of elderly patients treated by a PCT, and can promote improvement in prescribing strategies.
