Accuracy of terminology and methodology in economic analyses in otolaryngology.

OBJECTIVE: Economic studies increasingly guide health care resource allocation decisions. Because rigorous adherence to accepted definitions and research techniques is critical to ensure accuracy, we evaluated the terminology and methods of otolaryngology economic analyses. STUDY DESIGN: A total of 71 articles published from 1990 to 1999 in 6 peer-reviewed otolaryngology journals with terms such as "cost-effective" in their title or representing economic analyses were reviewed for terminology and use of established methodology guidelines. RESULTS: Over half (35 of 66) of terms such as "cost-effective" were used incorrectly, and 60% of articles (39 of 64) confused "charge" and "cost" data. Eleven percent (7 of 64) of papers specified the perspective of their analysis. About half (17 of 30) reported a summary measure such as a cost-effectiveness ratio. Only one third (23 of 63) performed sensitivity analyses. CONCLUSION: Adherence to accepted definitions and research methods is inconsistent, although we did note moderate improvements in making the distinction between costs and charges, defining of study perspective, and performing sensitivity analysis. SIGNIFICANCE: Greater attention to both terminology and methodology can enhance the quality of economic analyses and ultimately improve certain resource allocation decisions.

Effects of compensation method on physician behaviors.

OBJECTIVE: To examine physician and leader perceptions of the relationship between physician compensation and the productivity of physicians practicing in medical groups. STUDY DESIGN: Key informant interviews identified subjects' perceptions of factors influencing physician productivity and the behavioral effects of individual financial incentives. Interview transcripts were analyzed by a team of physicians, economists, and other researchers. STUDY POPULATION: Physicians, medical leaders, and group practice administrators (n = 114) representing 46 medical group practices in California, Oregon, Washington, and Wisconsin were interviewed. RESULTS: Five major themes emerged: (1) Most physicians reported that financial incentives did not substantially affect their own behavior, except for productivity. However, they suggested that specific compensation models do lead to certain seemingly undesirable physician behaviors. (2) By contrast, medical group leaders reported that financial incentives do affect a variety of physician behaviors. (3) Four productivity drivers emerged: financial incentives, demand-side factors, systems and infrastructure, and other individual or group attributes. (4) Physician compensation systems are evolving toward a blend of production-based and production-neutral incentives, plus new metrics aligned with the demands of managed care. (5) Culture, size, and specialty mix are significant determinants of group physician compensation systems. CONCLUSIONS: Compensation method is perceived to be a significant influence on physician productivity, particularly among group practice leaders. The changing context of medical practice represents another powerful "macro" lever on physician behavior.

Cost and cost-effectiveness of universal screening for hearing loss in newborns.

OBJECTIVE: To estimate the cost and cost-effectiveness of universal newborn hearing screening. STUDY DESIGN AND SETTING: Decision analysis model utilizing the hospital perspective. This model evaluated 4 distinct protocols for screening a fixed and defined hypothetical cohort of newborn infants. OUTCOME MEASURES: Cost of screening and the number of infants with hearing loss identified through universal screening. RESULTS: Otoacoustic emissions testing at birth followed by repeat testing at follow up demonstrated the lowest cost ($13 per infant) and had the lowest cost-effectiveness ratio ($5100 per infant with hearing loss identified). Screening auditory brainstem evoked response testing at birth with no screening test at follow-up was the only protocol with greater effectiveness, but it also demonstrated the highest cost ($25 per infant) and highest cost-effectiveness ratio ($9500 per infant with hearing loss identified). These findings were robust to sensitivity analysis, including best-case and worst-case estimation. The prevalence of hearing loss and the fraction of infants returned for follow-up testing had a large impact on the absolute level, but not relative level of protocol cost and cost-effectiveness. CONCLUSION: The otoacoustic emissions testing protocol should be selected by screening programs concerned with cost and cost-effectiveness, although there are certain caveats to consider. SIGNIFICANCE: The most significant barriers to implementation of universal newborn hearing screening programs have been financial, and this study compares the most common protocols currently in use. This study can assist program directors not only in the decision to initiate universal screening but also in their choice of screening protocol.
