OBJECTIVES: The aims of this study were to evaluate: (1) the prevalence and types of potentially inappropriate prescribing in older adults with hypertension or diabetes mellitus and hypertension, and (2) whether or not differences in the training of primary care physicians were associated with potentially inappropriate prescribing. MATERIALS AND METHODS: Primary care prescriptions issued by family physicians and general practitioners were audited using Screening Tool of Older Persons' Prescriptions criteria (version 1), with 18 out of 65 applicable criteria. Descriptive statistics were used to test the difference between proportions, and two-tailed t test was used for continuous variables. RESULTS: A total of 2,090 outpatient prescriptions were written during the study period; of these, 712 (34.1%) were potentially inappropriate. The mean number of drugs per patient was 6.03 (±2.5). Of the 712 prescriptions, 543 (76.3%) were used for the treatment of acute medical illnesses. The most common examples of potentially inappropriate prescribing were: orphenadrine (n = 174; 8.33%), long-term nonsteroidal anti-inflammatory drugs for > 3 months (n = 150; 7.18%), proton pump inhibitors for > 8 weeks (n = 135; 6.46%), antihypertensive therapy duplication (n = 59; 2.82%), long-acting glyburide (n = 48; 2.29%), and chlordiazepoxide for > 1 month (n = 44; 2.11%). Family physicians showed a greater tendency toward potentially inappropriate prescribing compared to general practitioners, but the difference was nonsignificant (n = 514 [34.75%] vs. n = 162 [31.3%]; p = 0.16). CONCLUSIONS: The prevalence of potentially inappropriate prescribing (i.e., 34.1%) was within the spectrum reported worldwide and unrelated to the training backgrounds of physicians. Most of the identified potentially inappropriate prescribing (76.3%) in older adults was associated with medications for acute medical illnesses and hence inappropriate polypharmacy should be discouraged.
