Preventive Cardiovascular Care for Hypercholesterolemia in US Emergency Departments: A National Missed Opportunity

Background: Hypercholesterolemia (HCL) affects nearly half of Emergency Department (ED) patients who present with possible acute coronary syndrome (ACS). However, it is unknown whether US ED providers obtain lipid panels, calculate 10-year atherosclerotic cardiovascular disease (ASCVD) risk, and prescribe cholesterol-lowering medications for these patients.

Methods: We conducted a nationwide cross-sectional ED survey from April 18, 2023, to May 12, 2023. An electronic survey assessing current preventive HCL care practices for patients being evaluated for ACS. A convenience sample was obtained by sharing the survey with ED medical directors, chairs, and senior leaders using emergency medicine professional organization listservs and snowball sampling. Responding EDs were categorized as being associated with an academic medical center (AMC) or not (non-AMC).

Results: During the 4-week study period, 110 EDs (50 AMC and 60 non-AMC EDs) across 39 states responded. Just 1.8% (2/110) stated that their providers obtain a lipid panel on at least half of patients with possible ACS and only one ED (0.9%) responded that its providers calculate 10-year ASCVD risk and prescribe cholesterol medication for the majority of eligible patients. Most reported never obtaining lipid panels (60.9%, 67/110), calculating 10-year ASCVD risk (55.5%, 61/110), or prescribing cholesterol-lowering medications (52.7%, 58/110).

Conclusions: The vast majority of US ED providers do not provide preventive cardiovascular care for patients presenting with possible ACS. Most ED providers do not evaluate for HCL, calculate ASCVD risk, or prescribe cholesterol-lowering medications for these patients.
