AbstractAims Potential prescribing omissions (PPOs) of medications are a frequent form of inadequate prescription drug practices. The objective of this study was to identify PPOs in a sample of elderly patients with cardiovascular disease. Methods Quasi-experimental study. Data were collected from a population database. We included patients who were older than 65 years and had a diagnosis of hypertension, dyslipidaemia, diabetes mellitus, coronary heart disease, heart failure or atrial fibrillation in Colombia. PPOs were determined in a random sample of patients by the START-2 (Screening Tool to Alert doctors to Right Treatment) criteria. The impact of the PPO was determined after an educational intervention with the doctors who were responsible for treating said patients. Results A total of 630 patients, with a median age of 72 years (interquartile range: 68-78 years), were included; 56.2% were women. The most frequent diagnoses were arterial hypertension (94.1%, n = 593) and dyslipidaemia (56.5%, n = 356). We identified 100 patients (15.9%) with omissions equalling 139 PPOs, and the most common PPOs were due to a lack of angiotensin-converting enzyme inhibitors in patients associated with heart failure or coronary heart disease (n = 23, 16.5%) and a lack of statins (n = 20; 14.4%) and aspirin (n = 20; 14.4%) in coronary heart disease. Prescription adjustments were achieved in 35 patients (25.2%). Conclusions Potential prescribing omissions are common in elderly patients with cardiovascular disease. Educational interventions may contribute to a reduced PPO frequency and improve the quality of prescription drug administration.© 2019 John Wiley & Sons Ltd.
