Relationship between patient race and the intensity of hospital services.

This study reviews evidence on whether services in United States hospitals vary by racial groupings of patients. The focus is on both equity and quality of hospital services. Patients with the diagnosis of pneumonia were studied at 16 randomly selected hospitals. The services and outcomes studied include five measures of the intensity of diagnostic and therapeutic services received by patients, and death rates during hospitalization. Multiple regression was used to control for patient health status at the time of entry into the hospital. Results are presented both before and after controlling for the effects of differences in the services offered between hospitals and patient payment sources. Our findings suggest that nonwhite pneumonia patients received fewer hospital services than expected on the basis of their health characteristics, and that their hospital lengths of stay were longer than expected. These findings were apparent when the hospitals were examined in aggregate and within individual institutions. No consistent differences in death rates were apparent. Possible explanations for these results are discussed. From our data, we conclude that patient race remains a potentially significant characteristic in determining the intensity of care provided to patients in hospitals, which is not explained by differences among racial groups in health status, source of payment, or site of hospitalization.

Does practice make perfect? Part II: The relation between volume and outcomes and other hospital characteristics.

The effect of a greater volume of patients with similar conditions being treated at a hospital on the outcomes achieved is investigated for almost 500,000 selected surgical and medical patients treated in over 1,200 nonfederal United States hospitals. In Part I the authors found strong and consistent evidence for surgical patients that high volume is associated with better outcome; evidence for medical patients was mixed. In this paper the authors include other hospital variables related both to volume and outcome--hospital size, teaching status, and expenditures--to determine whether they mask the true relationship; still, strong and consistent evidence that greater volume produces better outcome was found for both surgical and medical patients. This relation was significant for low-, medium-, and high-risk patients. Among the hospital variations added, only size was consistently and strongly related to outcome; greater size was associated with poorer outcome after accounting for volume. The potential importance of the findings for reducing deaths and days in hospital on a national level is discussed. The evidence is strongly supportive of the need for policies that would promote greater regionalization of a given service, and not greater size, to obtain better quality outcome for patients treated.

Does practice make perfect? Part I: The relation between hospital volume and outcomes for selected diagnostic categories.

The effect of a greater volume of patients with similar conditions being treated at a hospital on the outcomes achieved is studied using a variety of categories of patients, 15 surgical and 2 medical, and involving 550,000 patients treated in over 1,200 nonfederal United States acute care hospitals. After demonstrating that there are significant differences in the outcomes of patients, taking into account patient health status, the authors examine the impact of being treated in a hospital with a high or low volume of similar patients. Strong and consistent evidence is found that high volume is associated with better outcomes for surgical patients, which supports regionalizing patient care by procedure. Two additional variables, relative difficulty of the procedure and risk level of the patients, are analyzed to determine whether they change the relationship between volume and outcome. Some evidence is found that low-volume hospitals are associated with the poorest outcome for low-risk surgical patients. The evidence for medical patients is weak and mixed. Possible alternative explanations for the observed findings for surgical and medical patients are discussed.

Effectiveness in professional organizations: the impact of surgeons and surgical staff organizations on the quality of care in hospitals.

In this research, we examine the relative importance of different structural units in a professional organization, the hospital, as they affect organizational effectiveness. The difficulties of measuring effectiveness in a complex professional organization are discussed, and an adjusted measure of surgical outcome is developed. Data are drawn from a prospective study of over 8,000 surgical patients treated by more than 500 surgeons in 15 hospitals throughout the nation. Two different types of analyses are presented, both indicating that hospital features have more impact on surgical outcomes than do surgeon characteristics. The second analysis assesses the relative importance of specific attributes of the hospital, surgical staff organization, and surgeon characteristics on surgical outcomes.

Measuring the complexity and uncertainty of surgery and postsurgical care.

This article reports the results of a survey of a nationwide sample of more than 900 surgeons and post-surgical nurses, who were asked to rate the relative complexity and uncertainty of 71 surgical procedures frequently performed in hospitals. Average scores assigned to each surgical procedure by both types of raters are reported and the extent of agreement is assessed across indicator questions and types of raters. A surprisingly high level of agreement was observed. Explanations for the extent of agreement are discussed and uses for these scores are described.

Organizational determinants of services, quality and cost of care in hospitals.

Characteristics of hospitals may be useful predictors of the economy, efficiency, and effectiveness of services delivered. But it is difficult to explain the variables of cost and quality among hospitals until differences among patients and outcomes are accounted for. A promising new research approach is explored as a source of information on that most elusive of all measures in service organizations--the outcome experienced by clients.
