Shaping systems to promote desired outcomes. The magnet hospital model.

The organization of nurses' work is a major determinant of patient and staff welfare. Magnet hospitals have demonstrated organizational attributes that enable nurses to fully use their knowledge and expertise to provide high-quality patient care. The empirical evidence that this type of organization produces better patient and staff outcomes is compelling. Therefore when reconfiguring the delivery of care, the organizational form found in the magnet hospitals should shape systems to promote desired outcomes.

Satisfaction with inpatient acquired immunodeficiency syndrome care. A national comparison of dedicated and scattered-bed units.

OBJECTIVES: This study sought to determine whether there were differences in acquired immunodeficiency syndrome (AIDS) patients' satisfaction with inpatient nursing care on dedicated AIDS units compared with conventional, multidiagnosis medical units. METHODS: Interview data were collected from more than 600 consecutive AIDS admissions in 40 patient care units in 20 hospitals in 11 high AIDS incidence cities. Ten hospitals with dedicated AIDS units were matched with comparable hospitals treating AIDS patients on multidiagnosis medical units. AIDS patients' satisfaction with nursing care on dedicated AIDS units was compared with AIDS patients' satisfaction with care on scattered-bed units in the same hospital and with AIDS patients' satisfaction on scattered-bed units in different, matched hospitals without dedicated units. Interhospital differences that were not controlled by design were controlled statistically, as were differences in patient characteristics and illness severity. RESULTS: Acquired immunodeficiency syndrome patients receiving care on dedicated AIDS units were significantly more satisfied with their nursing care. In hospitals with units of both types, dedicated AIDS units had a higher proportion of white patients, men, and homosexuals, whereas scattered-bed units had more minority patients and intravenous drug users. Controlling for these factors as well as for differences in illness severity and interhospital differences in patient satisfaction did not diminish the positive AIDS unit effect on patient satisfaction. CONCLUSIONS: Dedicated AIDS units achieve higher levels of satisfaction among patients with AIDS than general medical units. There is no evidence that patients feel isolated or stigmatized on dedicated AIDS units compared with patients on general units, and many patients have a clear preference for dedicated units.

Hospital restructuring in the United States, Canada, and Western Europe: an outcomes research agenda.

OBJECTIVES: This article describes the extent and nature of hospital restructuring across the United States, Canada, and Western Europe, countries with differently organized and financed health-care systems, and assesses the feasibility of international research on the outcomes of hospital restructuring. METHODS: The conceptual background, context, and focus for the Bellagio conference on Hospital Restructuring in North America and Western Europe held in November 1996 is provided, illustrating key issues on hospital and workforce trends using the US data with international comparisons. RESULTS: Hospital systems internationally are undertaking very similar restructuring interventions, particularly ones aimed at reducing labor expenses through work redesign. Nursing has been a prime target for work redesign, resulting in changes in numbers and skill mix of nursing staff as well as fundamental reorganizing of clinical care at the inpatient unit level. Yet little is known about the outcomes of such organizational interventions and there are few efforts in place to critically evaluate these actions. CONCLUSIONS: Restructuring of the hospital workforce and redesign of work in inpatient settings is widespread and markedly similar across North American and Europe, and warrants systematic study. Cross-national studies of the impact of restructuring inpatient care on patient outcomes would yield valuable lessons about the cost-quality tradeoffs in hospital redesign and re-engineering, as well as inform national planning about the numbers and types of nurses needed in the coming decades.

Studying outcomes of organizational change in health services.

OBJECTIVES: The rapidly changing organizational context within which health care is delivered is altering provider-patient relations and processes of clinical decision-making, with significant implications for patient outcomes. Yet definitive research on such effects is lacking. The authors seek to underscore the contribution of organizational research to studies of clinical outcomes and demonstrates several approaches to further such efforts. METHODS: The authors present a theoretical framework of the operant mechanisms linking organizational attributes and patient outcomes. They use case examples from their ongoing research on hospitals to illustrate strategies for measuring these mechanisms and for overcoming some of the feasibility issues inherent in organizational research. RESULTS: Several methodological issues are explored: (1) exploiting "targets of opportunity" and "natural experiments" is a promising strategy for studying patient outcomes related to organizational reform; (2) indices of organizational traits, constructed from individual survey responses, can illuminate the operant mechanisms by which structure affects outcomes; and (3) secondary data sources and innovative statistical matching procedures provide a feasible strategy for constructing study comparison groups. Extending the organizational outcomes research strategy to new areas of inquiry offers an opportunity to enhance our understanding of how nursing organization affects outcomes. CONCLUSIONS: Improving the effectiveness of medical care in a health-care system undergoing fundamental restructuring requires greater understanding of how organizational context affects clinical outcomes. A higher priority should be placed on organizational outcomes research by researchers and funding agencies.

Hospital nurses' occupational exposure to blood: prospective, retrospective, and institutional reports.

OBJECTIVES: This study examined nurses risk of exposure to blood resulting from injuries with needles and sharps, the methods of estimating those risks, and the factors affecting risks. METHODS: Nurses on 40 medical units in 20 hospitals in cities with a high incidence of AIDS were studied. Percutaneous injuries were documented for every shift during a 30-day period. These prospective reports were compared with retrospective and institutional reports. Factors affecting the likelihood of injuries were explored. RESULTS: Based on the prospective reports, the rate of injuries to staff nurses was 0.8 per nurse-year. Prospective and retrospective rates were similar, while institutional rates were significantly lower. Factors associated with increased injuries included recapping needles and temporary work assignments. Working in hospitals characterized by professional nurse practice models and taking precautions to avoid blood contact were associated with fewer injuries. CONCLUSIONS: Injuries from needlesticks are more common than institutional reports suggest and do not occur at random. Diminishing the frequency with which nurses recap needles, increasing precautions they take, reducing use of temporary nursing personnel, and implementing organizational changes may lower the odds of nurses being injured.

Using existing health care systems to respond to the AIDS epidemic: research and recommendations for Chile.

Chile is a country with a relatively low prevalence of HIV infection, where successful prevention has the potential to change the future course of the epidemic. A controversial national prevention strategy based upon public education has emerged in response to characterizations of the epidemic as well-dispersed with a growing involvement of heterosexuals. This characterization is not consistent with the observed facts. There is a comparatively well-organized health care system in Santiago that is doing a good job of detecting HIV infection and already has in place the elements of a targeted intervention scheme. Chile should place priority on the use of the existing health care infrastructure for implementing both the traditional public health interventions for sexually transmitted diseases (contact tracing and partner notification) and the AIDS-necessitated strategy of focused counseling and education.

Effects of specialization and client differentiation on the status of nurses: the case of AIDS.

This is a study of how change in the organization of work within hospitals affects the disputes over contested professional jurisdictions. We employ the natural experiment in hospital work reorganization motivated by the AIDS epidemic to empirically document the effects of specialization and client differentiation on the increased intra-organizational status of nurses. We demonstrate that specialized AIDS units represent a form of hospital reorganization in which responsibility, authority, and autonomy devolve toward nurses. Measures of organizational outcomes are derived from the aggregated evaluations of the nurses working in 40 units in 20 hospitals. Our analyses show that different organizational forms are mirrored in differences in the presence of features related to the status and autonomy of nurses. Our work provides some new sociological perspectives on nursing and the changing medical division of labor.

The role of functional status in predicting inpatient mortality with AIDS: a comparison with current predictors.

To assess the independent prognostic role of functional status, as reflected by a measure of an inpatient's global requirement for nursing assistance with basic activities of daily living (Global ADL), we compared Global ADL with three validated AIDS mortality predictors: the Clinical AIDS Prognostic Staging (CAPS); the Severity Classification System for AIDS Hospitalization--version 2 (SCAH-2); and CD4 cell count. Our study sample consisted of 1392 patients with AIDS and a hospital stay of 3 or more days at one of 20 hospitals in 11 U.S. cities with high AIDS incidence. Data were collected from September 1990 through December 1991. Two percent of patients refused participation, and 26% were eliminated due to incomplete data collection, leaving an analytic sample of 1003 patients. Only 30% of patients had a CD4 count measured at any time during hospitalization. Cox regression was used to measure the hazard of inpatient mortality adjusted for length of stay. Overall mortality was 12%. Mortality rates for patients in Global ADL stages I-IV were 3%, 8%, 19%, and 51%, respectively (p < 0.0001). Global ADL more effectively discriminated mortality than CAPS (p < 0.001), SCAH-2 (p < 0.001), or CD4 count (p < 0.001). Global ADL also added independent information in analyses adjusted for both CAPS and SCAH-2: a single stage increase of Global ADL demonstrated a 1.9-fold increased hazard of death (CI: 1.6, 2.3). SCAH-2, assigned at discharge, was not strongly correlated with admission predictors (Global ADL: r = 0.17; CI: 0.11, 0.23 or CAPS: r = 0.03, CI: 0.02, 0.17). We conclude that Global ADL, alone or in tandem with other severity systems, provides an excellent severity adjustment for inpatient mortality with AIDS. Finally, CD4 cell counts were not routinely available and were not as predictive as Global ADL in the patients for whom both were available.

Medicare funding of nurse education. The case for policy change.

OBJECTIVES: To determine the magnitude and distribution of US Medicare funding for nursing education and to assess the extent to which Medicare funding contributes to meeting national health care workforce priorities. DATA SOURCES: Medicare Hospital Cost Report Information System, American Hospital Association Annual Survey of Hospitals, and National League for Nursing national surveys of schools of nursing. DATA ANALYSIS: Using hospital identifiers, data from three data sets were merged and analyzed to estimate percentage distributions of Medicare funding according to types of educational programs, hospital characteristics, and student enrollment. RESULTS: Fifteen percent of direct Medicare graduate medical education funding goes to hospitals for the training of nurses and paramedical personnel. Totaling approximately $174 million in 1991, 71% of these funds went to hospitals for nursing education costs. Most of the nation's teaching hospitals (289 of 381 Council of Teaching Hospitals member hospitals) and nurse education programs (1112 of 1484) do not qualify under existing policies for Medicare nursing education reimbursement. Sixty-six percent of Medicare nurse training funds, totaling $114 million in 1991, went to 145 hospitals operating diploma nursing programs; these programs produce less than 10% of nurse graduates. Three states (Pennsylvania, New Jersey, and Ohio) received nearly one half (48%) of the $114 million for diploma nursing education. CONCLUSIONS: Medicare is the largest single source of federal support for nursing education. Yet, the majority of Medicare nursing education funding goes to hospitals affiliated with an increasingly smaller, idiosyncratic subset of nurse training programs. Unlike graduate medical education, Medicare supports primarily preprofessional education in nursing. Graduate education, including the preparation of nurse practitioners, does not generally qualify for reimbursement. Medicare reimbursement for nursing education must be retargeted.

Organizational aspects of caring.

Caring is fundamental to competence in medicine. Expressions of humaneness in the relationship between doctor and patient foster bonds of trust, enabling doctors and patients to communicate in ways that enhance diagnosis, treatment, and compliance. To be effective, a caring attitude must be adopted by all persons involved in the delivery of health care. Components of caring can be specified, learned, and incorporated into routine medical practice. Through their impact on stress management and coping, as well as morale and job satisfaction, the organizational and administrative practices surrounding health care encounters decisively impinge on caring. The organizational and financial arrangements for enhancing the humane delivery of health care are examined.

Lower Medicare mortality among a set of hospitals known for good nursing care.

The objective of this study is to investigate whether hospitals known to be good places to practice nursing have lower Medicare mortality than hospitals that are otherwise similar with respect to a variety of non-nursing organizational characteristics. Research to date on determinants of hospital mortality has not focused on the organization of nursing. We capitalize on the existence of a set of studies of 39 hospitals that, for reasons other than patient outcomes, have been singled out as hospitals known for good nursing care. We match these "magnet" hospitals with 195 control hospitals, selected from all nonmagnet U.S. hospitals with over 100 Medicare discharges, using a multivariate matched sampling procedure that controls for hospital characteristics. Medicare mortality rates of magnet versus control hospitals are compared using variance components models, which pool information on the five matches per magnet hospital, and adjust for differences in patient composition as measured by predicted mortality. The magnet hospitals' observed mortality rates are 7.7% lower (9 fewer deaths per 1,000 Medicare discharges) than the matched control hospitals (P = .011). After adjusting for differences in predicted mortality, the magnet hospitals have a 4.6% lower mortality rate (P = .026 [95% confidence interval 0.9 to 9.4 fewer deaths per 1,000]). The same factors that lead hospitals to be identified as effective from the standpoint of the organization of nursing care are associated with lower mortality among Medicare patients.

Health care workforce priorities: what nursing should do now.

We provide an appraisal of the adequacy of the aggregate supply of nurses and the appropriateness of their educational mix in view of anticipated changes in health care. We view the supply as adequate, but the educational mix as deficient with regard to nurses with baccalaureate and higher degrees who will be in greatest demand in new and expanding roles. Five priority areas are identified in which nursing can make particularly important contributions to improving health and health care: restructuring hospitals, improving primary care availability, contributing to the viability of academic health centers, improving care of the underserved, and redesigning the role of public health in a reformed health care system.

Nurse practitioner managed care for persons with HIV infection.

This exploratory study examined whether outcomes of care for HIV-infected patients are related to whether the patient's primary provider is a physician (MD) or a nurse practitioner (NP). Functional status, symptom occurrence, self management, health service use and patients' assessment of their care were evaluated for 87 HIV-infected patients in a teaching hospital outpatient setting. NP patients were three times as likely to report their health status as only fair or poor (odds-ratio = 3.06, p = .028), and reported significantly more unpleasant symptoms over a four-week period. Despite being in poorer health than patients cared for by physicians, NP patients functioned at comparable levels and used no more health care services than MD patients. NP patients reported 45 percent fewer problems with their care (p = 0.003). Findings suggest that more extensive use of nurse practitioners could safely enhance access to care for persons with HIV-related illnesses.

Charting the future of hospital nursing.

Nursing roles are expanding in all health care settings; however, the majority of nurses will continue to practice in hospitals for the foreseeable future. Yet hospital nursing is experiencing great ferment and turmoil. Nurses are dissatisfied increasingly with hospital practice, and vacancy and turnover rates are high enough to raise major concerns about adverse consequences for patients. This paper focuses on the nature and causes of the current problems in hospital nursing and advances recommendations for charting a new course for hospital nursing.

Uninsured working-age adults: characteristics and consequences.

While estimates of the country's uninsured vary, ranging from 10 to 18 percent of the general population, virtually every study on use of medical services reports that lack of health insurance represents a major barrier to medical care. Based on the 1986 national Robert Wood Johnson Access Survey of 10,130 noninstitutionalized persons, the characteristics of working-age adults without health insurance, and the consequences, are examined. Among working-age adults, the uninsured are most likely to be poor or near-poor, Hispanic, young, unmarried and unemployed. Compared with the insured, they have significantly fewer ambulatory visits during a year, are less likely to have contact with a medical provider during a 12-month period, and are more likely to receive their care in a hospital outpatient clinic or emergency room. Differences in health status do not account for these findings. Especially among persons with chronic and serious illnesses, the uninsured are less likely than the insured to receive medical care. Further, the uninsured are significantly more likely to report needing but not receiving medical care, primarily for economic reasons, and although poorer, they have higher out-of-pocket medical expenses than others in the population.
