Effects of Guideline and Formulary Changes on Statin Prescribing in the Veterans Affairs.

ABSTRACT:

Objective

To compare the effects of two sequential policy changes-the addition of a high-potency statin to the Department of Veterans Affairs (VA) formulary and the release of the American College of Cardiology/American Heart Association (ACC/AHA) cholesterol guidelines-on VA provider prescribing.

Data sources/study setting

Retrospective analysis of 1,100,682 VA patients, 2011-2016.

Study design

Interrupted time-series analysis of changes in prescribing of moderate-to-high-intensity statins among high-risk patients and across high-risk subgroups. We also assessed changes in prescribing of atorvastatin and other statin drugs. We estimated marginal effects (ME) of formulary and guideline changes by comparing predicted and observed statin use.
