OBJECTIVE: To determine the percentage of patients over 65 years of age with potential problems derived from the consumption of medications, and identify associated variables. DESIGN: A descriptive cross-sectional study. SETTING: Otero y Paulino Prieto Health Centers (Oviedo). PATIENTS: A randomly selected group of 298 patients over 65 years. MEASUREMENTS AND RESULTS: A questionnaire using both interview and clinical case notes provided data about sociodemographic details, perceived state of health, and functional status of patients, and qualitative and quantitative aspects of pharmacological treatment. 222 valid questionnaires were obtained. Once having identified patients with potential treatment problems, the associated variables were studied using bivariant and multivariant analysis. The mean consumption of medications was 3.1. 32.9% of patients had treatment problems (95% CI, 26.7-39.1), identified as drug interactions (54.8%), inappropriate use (36.9%) or both (8.3%). The bivariant analysis showed an association between the presence of problems and number of medications consumed (p < 0.001), prescribers (p < 0.001), diagnostic (p < 0.001), number of visit/year (p < 0.004), patient's own perception of health (p = 0.006), age (p = 0.018), socioeconomic status (p = 0.024) and cultural level (p = 0.039); the associations was not significative for functional status (p = 0.150), sex (p = 0.246), and number of UTB (Use Therapeutic Low) drug used (p = 0.751). Logistic regression showed an association between the presence of problems and patient's perceived state of health (OR, 1.56; 95% CI, 1.03-2.36) and the number of medications consumed (OR, 1.67; 95% CI, 1.41-2). CONCLUSIONS: A third of the population studied showed potential problems derived from the consumption of medications, through drug interactions and/or inappropriate use. Variables associated with this problems are the patient's perceived ill-health, and the highest consumption of medications.
