Deprescribing, or the supervised process of intentionally reducing or stopping medication, has emerged as a strategy to reduce medication overuse and mitigate risks associated with taking multiple medications. 1 Odden and colleagues 2 evaluated the association of antihypertensive deprescribing with the risk of cardiovascular events, specifically myocardial infarction (MI) and stroke, among Veterans Health Administration long-term care residents. The investigators used an observational study design and electronic health record and administrative data with a target trial emulation framework approach, which helps estimate causal effects in situations like this one in which randomized clinical trials would be difficult. Based on data from 2006 to 2019 on 13 096 adults aged 65 years or older, 18% of patients had medications deprescribed, defined as discontinuation or a 30% or greater reduction in dose; after up to 2 years of follow-up, the estimated cumulative incidence of hospitalization for MI or stroke was 11.2% in patients whose medications were deprescribed vs 8.8% in those whose medications were not (adjusted hazard ratio, 0.93; 95% CI, 0.70-1.26). Overall, the authors concluded that the adverse consequences of antihypertensive medication deprescribing, particularly major cardiovascular events, were likely to be minimal in this population.The rigorous study by Odden et al 2 challenges some conclusions of existing literature on deprescribing, which is relatively limited in terms of recency and clinical setting. 3 While low blood pressure targets less than 130/80 mm Hg (and even 120/80 mm Hg) are recommended for many patients under current guidelines, determining the right threshold for patients with complex health status, like those in long-term care settings, is less clear. The authors had access to electronic health record data to verify blood pressure values at the time of deprescribing, with median systolic and diastolic values of 127 mm Hg and 69 mm Hg, respectively, in the deprescribed group and 129 mm Hg and 70 mm Hg, respectively, in the not deprescribed group; these findings suggest that discontinuing antihypertensive medication was appropriate in these patients. While the relevance of blood pressure variability is increasingly being recognized, the relationship between this variability and long-term cardiovascular outcomes remains unclear, leaving uncertainty about how antihypertensive deprescribing should influence clinical guidelines. Patients in the study who had antihypertensives deprescribed were also taking more and different medications, raising further unanswered questions about whether certain antihypertensives may be better deprescribing targets and which patients may be most appropriate for deprescribing interventions. As mentioned by the authors, future research should also expand beyond this predominately male population of US veterans to include more diverse populations and understand whether the effects of deprescribing differ by other meaningful characteristics.The study by Odden et al ...
