Characteristics of hospitals providing preventive services: does delivery system integration make a difference?

OBJECTIVE: As health care organizations consolidate into integrated delivery systems, increased delivery of preventive services is expected. The study objective was to evaluate the impact of hospitals' participation in multiorganizational arrangements and managed care on their delivery of preventive services. METHOD: The study is a secondary data analysis of data in the American Hospital Association 1993 Annual Survey of Hospitals Data Base. Two primary prevention variables (health promotion services to patients and to community members), and one secondary prevention variable (screening mammography) were included. Hospital characteristics included ownership, bed-size, and integration-participation in a multiorganizational arrangement and having managed care (HMO and PPO) contracts. RESULT: The 5,387 general medical and surgical hospitals responding to the 1993 survey were included in the analysis. Proportions of hospitals reporting delivery of health promotion services to patients, and to community members, and screening mammography services were respectively 90%, 83%, and 88%. Hospitals reporting participation in multiorganizational arrangements were more likely to report delivery of preventive services after adjusting for bed-size. The bed-adjusted odds ratios for providing health promotion services to inpatients, and to members of the community, and screening mammography services in hospitals with managed care contracts versus those without managed care contracts were respectively: 2.72 (95% CI: 1.65, 2.50), 2.03 (1.63, 2.53), and 1.51 (1.26, 1.81). CONCLUSION: Preliminary findings from this secondary data analysis support the expectation that current changes in the health care delivery system may expand the delivery of preventive services.

Medicare Peer Review Organization preprocedure review criteria. An analysis of criteria for three procedures.

The Medicare Peer Review Organization (PRO) program includes preprocedure review using explicit criteria to assess the appropriateness of specific procedures. This study evaluates the variability in the PRO preprocedure criteria for the three procedures most frequently reviewed by PROs: carotid endarterectomy, cataract removal, and cardiac pacemaker implants. In August 1989, the PRO review criteria were received from the Health Care Financing Administration. To provide a reference point for reviewing the PRO criteria, national practice guidelines for these three procedures were identified. Wide variability was demonstrated in the PRO procedure-specific carotid endarterectomy and cataract removal review criteria among PROs, and the criteria differed significantly from the identified practice guidelines. The criteria for cardiac pacemaker implants were somewhat less variable, and were based, to varying degrees, on practice guidelines developed by the American College of Cardiology (ACC). Greater attention is needed to improve the development of review criteria, including the use of relevant practice guidelines, to ensure that review criteria are optimal.

Appropriateness of medical care. Findings, strategies.

Concerns regarding significant levels of inappropriate medical services--as high as 20% or more--continue to influence discussions regarding medical care quality, utilization, and costs. The basis of these concerns are findings from a series of studies of the appropriateness of use of several medical and surgical services provided in the late 1970s and early 1980s--cardiac pacemaker implants, carotid endarterectomy, coronary artery bypass surgery, coronary angiography, and upper gastrointestinal endoscopy. More recent data from Medicare peer review organizations, however, indicate lower levels of unnecessary hospital admissions and medical services. Despite uncertainties regarding the extent of inappropriate care, additional efforts are required to better define appropriate medical care. A promising effort to meet this need is the development of practice parameters, which include practice guidelines and standards.

Sex-specific and race-specific hip fracture rates.

Sex-, race- and age-specific hip fracture rates were determined using Health Care Financing Administration data for Medicare-reimbursed hip fracture hospitalizations from 1980 to 1982. Rates were highest in White women, lowest in Black men, and intermediate in White men and Black women. Proportions of hip fracture patients dying during hospitalization and those discharged to nursing homes, respectively, were: White men (10.5%; 49%); Black men (9.3%; 32%); White women (5.0%; 54%); and Black women (8.2%; 30%).

Spirometry variability criteria--association with respiratory morbidity and mortality in a cohort of coal miners.

To clarify the association between spirometry variability and respiratory morbidity and mortality, the authors analyzed data for miners examined in the first round of the National Coal Study, 1969-1971, and they compared groups of miners who failed with those who met each of two spirometry variability criteria: a 5% criterion recommended by the American Thoracic Society, and a 200 ml criterion used in prior research studies. Compared with miners who met the 5% criterion (the best two forced vital capacities must be within 5% or 100 ml of one another), the group that failed had a lower mean for forced expiratory volume in one second (FEV1), and odds ratios for cough, phlegm, wheeze, shortness of breath, and death of 1.75, 1.67, 1.76, 2.71, and 1.30, respectively. The findings for the 200 ml criterion (the best two FEV1s must be within 200 ml of one another) were somewhat different. The group that failed versus the group that met this criterion had a higher mean for FEV1, and odds ratios for cough, phlegm, wheeze, shortness of breath, and death of 1.13, 1.07, 1.15, 1.43, and 0.94, respectively. Although the findings differ for the two criteria, the findings demonstrate that increased spirometry variability is associated with poorer health.
