The feasibility and accuracy of evaluating lipid management performance metrics using an electronic health record

Abstract

Background: Over the past decade, electronic health records (EHRs) have emerged as a potential tool to assess quality of care; however, the feasibility and accuracy of EHRs to assess adherence to lipid management performance measures have not been evaluated.

Methods: We created a retrospective cohort of 3779 patients with coronary artery disease who were followed up in a cardiology clinic at an academic medical center using an EHR database. Of these 3779 patients, 300 randomly-selected charts were reviewed to identify reasons for failure to adhere to lipid management performance measures.

Results: Based on the EHR, a low-density lipoprotein cholesterol measurement was obtained in 73% of patients within the past 3 years; of which, 34% had low-density lipoprotein cholesterol levels ≥100 mg/dL and statin therapy had been prescribed in 88%. Manual chart review revealed that many of these apparent failures were actually false positives, due to inaccurate capture of indications and contraindications to lipid measurement and statin prescription, patient/provider treatment preferences, and external data sources.

Conclusions: While it is possible to monitor adherence to lipid management performance measures using an EHR, the accuracy of this assessment is currently limited and may underestimate provider quality of care.
