While a staff member at the VA Medical Center Memphis, Dr. William Cushman was Co-Chair of the Diuretic Comparison Project (DCP) from its planning stages through recruitment of VA medical

centers/health care systems and patient selection. This large VA clinical trial found that the blood pressure drug chlorthalidone (CTD) was not superior to hydrochlorothiazide (HCTZ) for the

prevention of cardiovascular disease or non-cancer death. Both drugs, commonly known as water pills are used to help the body rid itself of excess fluid, which can lower blood pressure. The

Diuretic Comparison was conducted at 537 VA medical centers and community clinics in the U.S. The trial enrolled more than 4,000 providers and 13,500 Veterans with high blood pressure who

were taking HCTZ at baseline. Study participants were randomized to stay on their current dose of HCTZ or take an equivalent dose of CTD. The study was funded by the VA Cooperative Studies

Program. The study results were published online December 14, 2022, by the New England Journal of Medicine: CHLORTHALIDONE VS. HYDROCHLOROTHIAZIDE FOR HYPERTENSION–CARDIOVASCULAR EVENTS

Studies. Cushman was Chairman for PATHS (Prevention and Treatment of Hypertension Study), a multicenter clinical trial examining the effects of reducing alcohol intake on blood pressure in

heavy drinkers and led the VA participation in the Antihypertensive and Lipid Lowering Treatment to Prevent Heart Attack Trial (ALLHAT), a National Heart, Lung and Blood Institute (NHLBI)

study comparing cardiovascular events from four major classes of antihypertensive agents. He was Co-Chair for the Diuretic Comparison Project (DCP), a randomized VA Cooperative Study

comparing the effects of chlorthalidone vs hydrochlorothiazide on major cardiovascular events. Cushman was also Principal Investigator for the VA Clinical Center Network and Chair of the
