Measuring utility values for QALYs: two methodological issues.

Abstract

Two methodological concerns in utility estimation, the development of health state descriptions (scenarios) and the interpretation of interval scale anchor points, are examined in the context of disease-specific cost utility analyses (CUA). It is contended that results in CUA can be fundamentally biased by: (i) how the information presented in a scenario is generated; and (ii) the researcher's 'definition' of anchor points, when these are used as bounds to the interval scale. A number of recommendations are made, in particular for a more explicit reporting of these issues in CUA, to facilitate greater consistency in the application of utility measurement techniques.

Prospective development of a cost-efficient program for the pubovaginal sling.

OBJECTIVES: We designed and implemented a cost-containment program for patients undergoing a pubovaginal sling procedure. We sought to test the hypothesis that preoperative patient education could reduce the length of hospital stay in these patients. Our goal was to decrease hospital charges while maintaining quality of care. METHODS: A multidisciplinary group of clinic and hospital staff identified factors that contribute to a patient's hospital charges for a pubovaginal sling procedure. A program of preoperative patient education to teach intermittent self-catheterization was combined with the elimination or control of items considered unnecessary to the delivery of safe, efficient care. Patient care was standardized from the preoperative visit to discharge planning. The difference in the mean values of 38 prestudy patients was compared with 15 study patients with a Wilcoxon rank sum test. RESULTS: Length of hospital stay was reduced from a mean of 2.8 to 1.1 days after implementation of the program (P < 0.0001). This decreased length of stay, combined with a reduction in routine laboratory studies (97% decrease; P < 0.0001), operating room charges (11% decrease; P < 0.01), and medications (35% decrease; P < 0.01), led to significantly reduced hospital charges. Total hospital charges decreased by 35%, from a mean of $4862 to a mean of $3153 (P < 0.0001). There was no increase in morbidity. Patient satisfaction with length of hospital stay did not change significantly following implementation of the program. CONCLUSIONS: With a program of preoperative patient education combined with a critical review of the factors contributing to a patient's hospital charges, it is possible to implement a cost-efficient program for a pubovaginal sling, leading to a 35% reduction in mean total hospital charges. This approach directed toward other incontinence procedures could be expected to yield comparative results.
