Quality of care in teaching hospitals: a literature review.

PURPOSE: To compare the quality of care in teaching hospitals with that in nonteaching hospitals. METHOD: By performing a literature review via PubMed, the author identified and surveyed 23 studies that compared the quality of care in teaching hospitals with that in nonteaching hospitals. The studies were published from 1989-2004 and in all but one case dealt exclusively with U.S. hospitals. RESULTS: The teaching hospitals studied had better-quality measures than did nonteaching hospitals in the predominant number of studies reviewed. Process measures were significantly better in teaching hospitals in seven of the eight studies where such measures were observed, and equal in the other study. Risk-adjusted mortality was lower in teaching hospitals in nine of the 15 studies using that measure, not significantly different in five, and significantly lower in nonteaching hospitals in one study (in pediatric intensive care units, even though the teaching hospitals had a better process of care). In nonmortality outcomes, teaching hospitals were better in one study using that measure; there were no significant differences in five other such studies. Major teaching hospitals had more favorable outcomes end points than did minor teaching hospitals in eight studies in which they were compared. Including only those six studies using clinical data for process analysis or risk adjustment, teaching hospitals had a better process in all six and lower adjusted mortality in five of seven studies where that measure was used. CONCLUSIONS: Overall, the favorable results in teaching hospitals extended over a range of locations, conditions, and populations, including routine as well as complex conditions. However, the quality measured in these studies was not at target levels across the spectrum of hospitals. There needs to be a continuous and determined effort for improvement in all institutions. It is to be hoped that teaching hospitals will take the lead not only in continuously improving their own quality, but also in developing and evaluating ever improving methods of quality assessment.

Creating a new structure for research on health care effectiveness.

Effectiveness research (a term we use in preference to the more confining and difficult health services or outcomes research) evaluates the clinical setting and the health care system on which it depends. It uses a variety of health care assessment techniques and the practical clinical trial to inform clinical practice, quality interventions, and health policy decisions. Effectiveness research had not had sufficient public or private funding to produce the information needed to facilitate evidence-based health care improvement. However, recent trends, such as the likelihood for continued substantial increases in health care costs and concern regarding the quality and safety of the US health care system, are among the important arguments for increasing its funding and capacity. We propose a new entity, a public-private consortium to expand and offer new capability and resources in this area. The consortium would consist of all relevant public and private entities. It would be organized into an executive committee, which would identify research priorities and panels to design requests for proposals. Competitive peer-reviewed proposals, transparency and balance of forces in choice of topics, conduct of research, and interpretation of results would be important features. Metrics for success would be use of the data derived from consortium projects in medical decision making and benefit design. The consortium would provide balance and potential mediation of conflicting or competing interests in which all stakeholders will be present to establish the rules. Broad representation of all interests would serve to avoid the economic, policy, and political issues that have bedeviled past efforts. Models for the consortium include the Health Effectiveness Institute, the Centers for Education and Research on Therapeutics, and the Transportation Research Board.

Changes in rates of beta-blocker use in community hospital patients with acute myocardial infarction.

OBJECTIVE: To examine changes in the rate of beta-blocker (BB) use at admission, in hospital, and at discharge between 1994 and 1995 (MICH I) and 1997 (MICH II) in patients with acute myocardial infarction (AMI). DESIGN: Comparison of two prospectively enrolled cohorts. SETTING: Five mid-Michigan community hospitals. PATIENTS: We studied 287 MICH I patients and 121 MICH II patients with AMI who had no contraindications to BB use from cohorts of consecutively admitted cases of AMI (814 in MICH I; 500 in MICH II). RESULTS: Prescription of BBs to ideal patients with AMI increased in patients with previous history of myocardial infarction on arrival at the hospital (12.5% vs 36.0%; P= .01), in hospital (47.0% vs 76%; P < .01), and at discharge (34.0% vs 61.9%; P < .01). Neither race nor gender was a predictor of BB use. Younger age predicted BB prescription at discharge (odds ratio [OR], 2.07; 95% confidence interval [CI], 1.32 to 3.23). Later study cohort was the most important predictor of BB use in hospital (OR, 3.4; 95% CI, 2.09 to 5.25). CONCLUSION: BB use improved dramatically over the study period, but additional work is needed to improve use of BB after discharge and among elderly patients with AMI.

Realized access to physician services among the elderly in West Texas.

The purpose of this study is to identify populations in a sparsely populated region that are less likely to obtain medical care. We conducted a cross-sectional survey of more than 5,000 elderly persons who participated in telephone interviews after being identified through more than 65,000 calls to residential listings. Subjects were persons aged 65 years and older who resided in 108 counties in western Texas. The response rate was 72%. The probability of seeing a physician in the last 6 months for urban and rural residents was modeled using multiple logistic regression analysis. Among rural residents, characteristics that were significantly (p < 0.05) associated with not recently visiting a physician when health status is held constant included belief in home remedies, having less than a high school education, lack of health insurance, and low income. Among urban residents, Hispanic ethnicity and skepticism about medical care were negatively associated with having a recent visit, whereas being religious was positively associated. Despite the availability of Medicare coverage, several subgroups of the elderly population have impaired access to medical care in this sparsely populated region. Intensified outreach efforts are indicated.

Atropine Sulfate Premedication and Cardiac Arrhythmia in Electroconvulsive Therapy (ECT).

Prophylactic effects of atropine sulfate as a premedication for cardiac arrhythmia were studied in 44 patients receiving electroconvulsive therapy in a randomized, cross-over, double-blind design. Cardiac rhythms were recorded with Holter monitors during atropine sulfate and placebo treatments. Vagal arrhythmia seemed to be reduced with atropine sulfate premedication, but the frequency of ventricular arrhythmia was not affected.
