Underuse of statins for secondary prevention of atherosclerotic cardiovascular disease events among ambulatory surgical patients.

Abstract

Although statins are highly effective for reducing cardiovascular disease events, prior studies demonstrate their significant underuse in the US population, including among those with known atherosclerotic disease. It is unknown whether this finding applies to the subset of patients who present for outpatient surgery, as such patients would be expected to have recent exposures to healthcare providers during the preoperative referral period. The primary aim of this manuscript was to ascertain the prevalence of statin underuse and associated risk-factors for such underuse among ambulatory surgical patients with documented atherosclerotic cardiovascular disease. This was a retrospective observational study of a random sample of 600 patients ages 40-75 years presenting for ambulatory surgery within a 6-month period in 2016, at one of three ambulatory surgical centers affiliated with a large, tertiary care hospital. Compilation and analysis of data occurred in 2018-2019. Of the 600 subjects, 117 (19.5%) had documented atherosclerotic cardiovascular disease. Within this high-risk group, only 71 (60.7%) carried a prescription for any statin, and only 30 (25.6%) were prescribed a recommended high intensity statin dose for secondary prevention. In a multivariable logistic regression analysis, older age, male sex, and treatment for hypertension were positively associated with statin use. In conclusion, statin underuse among ambulatory surgical patients is common and mirrors what has been observed in non-surgical populations. Future trials are needed to investigate the possible role of surgical teams to promote guideline-based statin therapy, including the role of preoperative screening interventions to impact long term cardiovascular morbidity and mortality.
