Cost perspectives of laparoscopic and open appendectomy.

BACKGROUND: Despite multiple studies comparing laparoscopic and open appendectomies, the clinically and economically superior procedure still is in question. A cost analysis was performed using both institutional and societal perspectives. METHODS: A decision analytic model was developed to evaluate laparoscopic and open appendectomies. The institutional perspective addressed direct health care costs, whereas the societal perspective addressed direct and indirect health care costs. Baseline values and ranges were taken from randomized controlled trials, meta-analyses, and Medicare databases. RESULTS: From the institutional perspective, open appendectomy is the least expensive strategy, with an expected cost of $5,171, as compared with $6,118 for laparoscopic appendectomy. The laparoscopic approach is less expensive if open appendectomy wound infection rates exceed 23%. From the societal perspective, laparoscopic appendectomy is the least expensive strategy, with an expected cost of $10,400, as compared with $12,055 for open appendectomy. CONCLUSIONS: The decision analysis demonstrated an economic advantage to the hospital of open appendectomy. In contrast, laparoscopic appendectomy represents a better economic choice for the patient.

Cigarette smoking and functional ovarian cysts.

This population-based case-control study assessed the effect of current cigarette smoking on the risk of functional ovarian cyst development. Cases were all 15-39 year-old enrollees of Group Health Cooperative of Puget Sound (GHC) who had either an inpatient primary diagnosis of functional ovarian cyst in 1988 or 1989 (n = 61) or an outpatient primary diagnosis of functional ovarian cyst at five GHC primary care clinics (n = 37). Controls were randomly selected enrollees matched to cases on age, primary care clinic, and enrollment date (n = 239). A total of 36.7% of cases and 20.5% of controls were determined by medical record review to be current smokers. Compared with women who were not current smokers, the relative risk of a diagnosed functional ovarian cyst among smokers was 2.0 (95% confidence interval 1.1-3.5). This finding, in an area of little previous research, provides a promising lead in the investigation of the etiology of functional ovarian cysts and the effects of smoking on ovarian function in general.

Moving from "small qa" to "large qa". An outcomes framework for improving quality management.

In this article we describe an "outcomes framework" for planning and analyzing quality management systems in relation to their ultimate purpose, enhancing the wide range of health care benefits. "Small qa" includes those methods that focus on structure or process and induce improvement of outcomes. These methods are essential but, predictably, often involve minimal improvement of health care. "LARGE QA" is defined as those methods that focus on unacceptable outcomes and deduce processes and structures to be changed to enhance outcomes. These methods focus on either "problems" or "opportunities" that predict substantial improvement in health care benefits. We briefly describe and analyze this outcomes framework for quality management in terms of its conceptual factors and its current and future emphasis. We then describe several major national program developments and resources that will facilitate moving the balance of quality management effort from small qa to LARGE QA.
