Evaluating cancer costs in NCI trials

Cost of care for patients in cancer clinical trials

BACKGROUND

Information on the costs of medical care for patients enrolled in clinical trials is needed by policymakers evaluating ways to facilitate clinical research in a managed care environment. We examined the direct costs of medical care for patients enrolled in cancer clinical trials at a large health maintenance organization (HMO).

METHODS

Costs for 135 patients who entered 22 cancer clinical trials (including 12 breast cancer trials) at Kaiser Permanente in Northern California, from 1994 through 1996 were compared with costs for 135 matched control subjects who were not enrolled in such trials. Cancer registry data and medical charts were used in matching the control subjects to the trial enrollees with respect to cancer site, stage, date of diagnosis, age, sex, and trial eligibility. The direct costs of medical care were compared between trial enrollees and the control subjects for a 1-year period, with data on costs and utilization of services obtained from Kaiser Permanente databases and medical charts.

RESULTS

Mean 1-year costs for the enrollees in trials were 10% higher than those for the control subjects ($17 003 per enrollee compared with $15 516 per control subject; two-sided P =.011). The primary component of this difference was a $1376 difference in chemotherapy costs ($4815 per trial enrollee versus $3439 per control subject; two-sided P<.001). Costs for the 11 enrollees in trials that had a bone marrow transplant (BMT) arm were approximately double the costs for their matched control subjects (borderline significance: two-sided P=.054). The $15 041 mean cost for the enrollees in trials without BMT was similar to the $15 186 mean cost for their matched control subjects.

CONCLUSIONS

Participation in cancer clinical trials at a large HMO did not result in substantial increases in the direct costs of medical care.

Federation of European Cancer Societies. Full report. Economic evaluation in cancer care: questions and answers on how to alleviate conflicts between rising needs and expectations and tightening budgets

All Western countries have experienced a fast growth in their healthcare expenses over recent decades. It is expected that pressure for such growth will continue in the future. But spending an ever larger share of our nation's resources on healthcare cannot be afforded. As a consequence, making choices will become more and more inevitable, even in cancer care. Economic evaluation is a very supportive tool for such decisions. This position statement concludes with recommendations for providers and healthcare policy-makers, to safeguard and further improve good clinical decision making and healthcare policy in cancer care under tightening budgets.
