Resource utilization implications of treatment were able to be assessed from appropriately reported clinical trial data

Background and Objective: Published clinical trial data rarely allow assessment of the health care resource utilization implications of treatment. We give an example of how these can be assessed given appropriate tabulation of data. Methods: Data from a trial comparing long-acting nifedipine gastrointestinal therapeutic system to placebo in 7,665 patients with stable angina pectoris was analyzed. Results: Relative to placebo, nifedipine significantly increased mean cardiovascular (CV) event-free survival by 41 days but had no effect on mean survival. Per 100 years of follow-up, 78.1 patient-years of double-blind nifedipine administration reduced use of another calcium antagonist, an angiotensin converting enzyme inhibitor, an angiotensin receptor blocker, a diuretic and a cardiac glycoside by 1.54, 3.73, 2.63, 2.23, and 0.64 years, respectively, whereas 0.21 less hospitalization for overt heart failure, 0.47 less hospitalization for any stroke or transient ischemic attack, 0.8 less coronary angiogram, 0.38 less coronary bypass procedure, and 0.13 additional orthopedic procedure was required. Combining resource utilization with cost data for one particular hospital showed that one additional year of CV event-free survival costs an average additional €3,036 in the setting considered. Conclusion: Appropriately tabulated clinical trial data allows clinicians to judge the resource utilization implications and economic effect of treatment decisions.
