Objectives.The authors compare the extent and nature of triazolam use before and after its deletion from a health maintenance organization's (HMO) open and advisory-type drug formulary.Methods.Benzodiazepine dispensings of HMO members were collected for the 3 years before (1989-1991) and for the 2 years after (1992-1993) the deletion of triazolam from the HMO's drug formulary. The number of triazolam users, their sex and ages, total annual exposure, estimated daily doses, and total days of annual exposure were calculated and compared before and after its deletion from the formulary.Results.From being the most frequently dispensed short-acting benzodiazepine in the HMO in 1989, the prescribing and use of triazolam decreased tenfold by the end of 1993. The effect on who was using the drug and how it was being used was less dramatic. The elderly were frequent longterm users and had the longest exposure to the drug.Conclusions.An open and advisory-type formulary can affect providers' drug selection behavior.

Objectives.Do not resuscitate (DNR) orders are increasingly common, though there has been little evaluation of their changing use. The authors contrasted the use and outcomes of DNR orders for nationally representative samples of Medicare patients hospitalized with specific diagnoses in 1981 to 1982 and 1985 to 1986.Methods.Using ordinary least squares regression to adjust for patient and hospital characteristics, the authors compared use, timing and predictors of DNR orders, and survival to hospital discharge of patients with DNR orders between the two time periods.Results.After adjustment for sickness at admission and for patient and hospital factors, more patients received DNR orders in 1985 to 1986 than in 1981 to 1982 (13% versus 10%,P<0.001), with most of the increase among patients with the greatest sickness at admission. Disparity in DNR order use by age, diagnosis, functional status, preadmission residence, and gender found in 1981 to 1982 was still present in 1985 to 1986. DNR orders were written earlier in hospitalization during the latter time period. Patients with DNR orders were more likely to survive to hospital discharge in 1985 to 1986 than in 1981 to 1982 (44% versus 36%,P=0.001), but their 30-day survival did not differ.Conclusions.Although use increased, disparities in DNR order assignment persisted in these 1980s data. Examination is needed into whether these differences persist and whether they reflect patient preferences. Systems should be developed to preserve and review the preferences of the increasing number of patients discharged after in-hospital DNR orders.

摘要:

Objectives.The purpose of this study was to examine the national variability in patient-level cost and length of stay for coronary artery bypass grafting (CABG) in Medicare patients.Methods.Retrospective multivariate regression analysis was done using Medicare administrative files and American Hospital Association files. Patients in the study had an International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedure code for CABG, with accompanying 1990 procedure date, in the Medicare Provider Analysis and Review File (n = 92,449).Results.Outcome measures used were inpatient cost (exclusive of professional fees) and inpatient length of stay associated with bypass admission. The national average cost of bypass surgery was $22,847 (median $18,783), with an accompanying average length of stay of 16 days (median 13 days). Multivariate regression analysis revealed that patient-level cost and length of stay were related to clinical, demographic, hospital, and regional characteristics (R2= 25% and 16%, respectively). After accounting for these characteristics at the patient level, considerable variation among states persisted in both cost and length of stay. In addition, states with similar adjusted lengths of stay varied widely with respect to adjusted cost. No relation was found at the state level between level of resource use and either procedural mortality or 60-day mortality/readmission rates.Conclusions.Considerable variability exists among states in patient-level cost and length of stay for CABG surgery, after adjusting to the extent possible for clinical, demographic, hospital, and regional characteristics. The lack of association at the state level between resource use and rates of mortality and hospital readmission suggests that costs could be reduced in many areas of the United States without compromising quality of care.

摘要:

Objectives.The purpose of this randomized controlled trial was to test the efficacy and effectiveness of process consultation consisting of a series of nurse manager-consultant problem-solving meetings for leadership development that would lead to their staff's improved morale, quality of care, and reduced absenteeism.Methods.Thirteen consenting clinical inpatient units were stratified for four variables known to affect outcome and were then randomly assigned to treatment and control conditions. The nurse managers from the seven experimental units were paired with outside nurse consultants from the McMaster University School of Nursing (Hamilton, Ontario, Canada) in a cooperative form of retraining in problem-solving through process consultation.Morale was determined through measures of perceptions of the work environment, an attitude scale concerning work (alienation), a personality measure (hardiness), and one of each scale for work satisfaction and for sources of satisfaction and dissatisfaction. Demographic data and information regarding family life responsibilities were collected as well. Assessment of quality of care was determined by the frequency and type of incident reports and by patients' perception of their satisfaction. A ratio of absence hours to total paid hours of work was used to compare experimental and control units' absenteeism rates.Results.Experimental subjects reported a statistically significant improvement in the characteristics of their work setting and in the quality of working relationships. The consultation process facilitated a perceived change in the organizational context of the experimental hospital units with less centralization of authority and more clarity about expectation. These organizational changes were accompanied by improved working relationships and less alienation from work. There was no statistically significant difference in absenteeism. However, a subanalysis of the units by "dose" of the intervention identified those who benefited from the effects of the consultation. Subjects whose nurse managers participated more actively in the consultation process accounted for the changes in working relationships and perceived organizational changes. The "low-dose" experimental subjects were more like the control subjects, with the exception of absenteeism, for which they had higher rates.Conclusions.The findings of this study suggest that process consultation can alter the staff's perceptions of the characteristics of the work setting, can reverse negative attitudes (alienation), and can create a more positive and supportive working environment (improved working relationship). However, the results suggest the need to target this type of intervention to managers who have the personal resources to engage in self-evaluation and personal development and thus to participate in the consultative process.

摘要:

Objectives.The authors compute and compare productivity growth in the health-care sectors for a sample of Organization for Economic Cooperation and Development countries over the period from 1974 to 1989. The authors compute Malmquist productivity indexes, which allow productivity growth to be decomposed into efficiency changes and technical change. These indexes also allow the use of primary quantity data (recently available from the Organization for Economic Cooperation and Development), rather than expenditure data, which the authors argue reduces bias resulting from distorted prices.Methods.The authors specify two models. The first model focuses on the hospital sector; inputs include physicians and medical care beds, whereas outputs are the "intermediate" type used in hospital efficiency studies, namely, inpatient days and discharges.Results.For the 19 countries with complete data, the authors found little productivity growth based on this model (with the exception of Denmark, with 15.4% cumulated growth, and the United States, with about 5% from 1974 to 1989). The authors did find, however, that the highest productivity levels are found in the United States (Italy and Finland were also on the frontier of technology in the base period, 1974). The second model uses the same inputs as the first (but in per capita terms), but it specifies simple proxies of health outcomes as outputs: life expectancy of women at age 40 and the reciprocal of the infant mortality rate.Conclusions.For the 10 countries with complete data for this model, the authors found evidence of much more widespread and rapid productivity growth: Denmark's cumulated growth was close to 33%, with the United States close behind. In both these countries, this growth was due solely to technical change over this period.

摘要:

Objectives.This study examines the use of the patient review instrument (PRI), a reimbursement reporting system used by the New York State Department of Health, to assess quality of care based on risk-adjusted outcomes.Methods.Data for all residents in approximately 550 nursing homes in upstate New York are used to develop five risk-adjusted outcome measures. The five measures are rates of decline in functional status activities of daily living (ADL), rates of increases in severity of decubitus ulcers, physical restraints rates, dehydration rates, and rates of major accidents. Logistic models are used to adjust for individual patients' risk factors. The face validity, content, construct, and criterion validity of these measures is examined.Results.Measures based on ADL decline, deterioration in decubiti, and physical restraints rates met all validity criteria and were correlated significantly with deficiency citations. Measures based on accident rates and rates of dehydration did not perform as well. There was significant variation in these quality measures across regions and between for-profit and nonprofit nursing homes.Conclusions.Information about quality of care is important to the efficient operation of competitive markets. Such information, however, often is costly to obtain and not available to individual patients. This study demonstrates that valid risk-adjusted outcome measures of quality can be developed based on data collected for reimbursement purposes.

摘要:

Objectives.The authors assess (1) the effects of first-dollar prescription drug insurance coverage provided by the Ontario Drug Benefit plan at age 65 on prescription drug use by seniors, and (2) the differential effects of this coverage on prescription drug use by seniors with varying levels of health status.Methods.The authors modeled self-reported prescription drug use contained in the 1990 Ontario Health Survey as a function of eligibility for coverage, controlling for health status and other factors. The two-part model was used and was estimated by maximum likelihood.Results.The provision of first-dollar prescription drug insurance coverage at age 65 is associated with an increase in drug use. Increases in drug use are, however, concentrated primarily among individuals with lower levels of health status. Most of the increased use occurs among individuals already under physician supervision, ie, an increase in the level of use among drug users rather than an increase in the probability of use.Conclusions.As Ontarians turn age 65 and become eligible for publicly subsidized prescription drugs, their use increases but the effect appears to be restricted mainly to persons with lower levels of health status. Given a growing trend toward reduction of public subsidy and increased reliance on patient cost sharing, more research is needed to quantify the use and health effects of such initiatives.

摘要:

Objectives.Market forces make it essential to know what policies and actions influence patients' reports of hospital services. No studies have examined the role of patient characteristics, labor quality and staff characteristics, nonlabor resources, managerial practices, and employee attitudes within a single investigation.Methods.The authors collected, simultaneously, data about labor, management and service processes, nonlabor resources, and employee attitudes on 117 nonintensive medical-surgical inpatient units in 17 hospitals selected from a pool of 69 institutions within a metropolitan area by a stratified random sample. Of the 2,595 patients who agreed to participate, 2,051 (79%) completed telephone interviews regarding their experiences with physical care, education, and pain management services within 26 days of hospital discharge.Results.A significant amount of variation in patients' service reports was explained (adjusted R2= 0.41 physical care, 0.35 pain management, 0.44 education). Although the predictors varied for each service report, patient characteristics, especially those related to personal resources, had a large explanatory role. A labor assignment pattern that could explain why earlier studies found labor quality and staff characteristics to have only a weak role in the prediction of patients' service reports was noted.Conclusions.The results related to patient characteristics may indicate opportunities to improve care by confronting service design strategies that erroneously rely on a homogeneous patient population. Measurement challenges identified by this study must be addressed to determine the role of labor quantity and staff characteristics.
