Gala P, Moshokgo V, Seth B, et al. - Given a high occurrence of antihypertensive medication errors and a strong link between medication errors and inadequate blood pressure control has been shown in medication reconciliation studies from high-income countries, however, there is a lack of data from low- and middle-income countries, and therefore, researchers undertook this cross-sectional analysis to assess the frequency of uncontrolled hypertension, the frequency and type of medication errors resulting in differences between patient-reported and prescribed antihypertensive medications, and the link between medication errors and uncontrolled hypertension. Among 280 enrolled adult patients receiving pharmacologic treatment for known hypertension, from Kweneng East District, Botswana, the prevalence of uncontrolled hypertension was estimated to be 55%, and ≥ 1 medication error was reported in 95 (34%). Errors that were reported most often were: patients receiving medications incorrectly (11.1%; 31/280), the omission of medications by patients (7.9%; 22/280), and unfilled prescriptions caused by pharmacy stock outs (7.5%%; 21/280). A significant link of uncontrolled hypertension with having ≥ 1 medication error vs no errors was reported. Findings revealed a strong link of medication errors with poor blood pressure control in this setting.
