[Inappropriate prescription in the community elderly, are we aware of?]

Objectives: To analyse the prescription according to the STOPP (Screening Tool of Older Person's Prescriptions) and Beer's suitability criteria, and associated factors in patients over 85 years-old.

Patients and methods: Cross-sectional study of inappropriate prescribing to over 85 year-olds. The data recorded were: sociodemographic variables, cardiovascular risk factors, chronic illnesses, multiple medication (or polypharmacy) (4 or more) and geriatric assessment. The inappropriate prescription (IP) was evaluated according to total and cardiovascular prescription.

Results: The mean number of drugs in the total of 78 subjects was 6.1 (3.3). Of the total number, 34.6% patients had 1 IP drug; 19.2% had 2; 15.4% had 3 or more, and in total 69.2% of patients had at least one IP drug, and 37.2% had 1 or more IP cardiovascular drugs. The therapeutic groups involved in the overall IP were benzodiazepines (BZP) 23.1%, loop diuretics 17.9%, selective serotonin reuptake inhibitors (SSRIs) 16.7%, and non-steroidal anti-inflammatory drugs (NSAIDs) made up 10.3% of the total criteria. The bivariate analyse found a relationship between the number of drugs and multiple medication (P=.030 in both) and total IP, with no significance found in cardiovascular IP. The multivariate analysis showed an association between multiple medication (OR: 1.22; 95% CI: 1.02-1.47; P=.031) and total IP, and dyslipaemia (OR: 0.30; 95% CI: 0.10-0.87; P=.026) and AHT (OR: 0.15; 95% CI: 0.03-0.78; P=.024) for cardiovascular IP.

Conclusions: More than half the over 85 year-old patients received an inappropriate prescription. Dyslipaemia and AHT are associated with an inappropriate cardiovascular prescription, and the most frequent drug groups were, BZP, diuretics, SSRIs, and NSAIDs.
