The oversupply of physicians: implications for hospital planning.

In the next ten years, hospitals will have to contend with the impact of group practice, which often competes with hospital-based services. How will a new interdependence between hospitals and group practices affect hospitals' strategic planning?

The use of correlative SEM and TEM to study thrombocyte and platelet adhesion to artificial surfaces.

Platelet adhesion is a complex process involving circulating cells, the damaged vessel wall and the complex medium of plasma in which the events take place. Elucidation of several cellular changes which occur during adhesion has been enhanced through the use of conventional transmission and scanning electron microscopy; however, many question, particularly relating to cytoplasmic control of cellular reorganization have remained unanswered. This paper describes the preparative techniques and the potential for use of correlative stereo SEM and TEM in studies of platelet adhesion. Three particular techniques: (1) stereo SEM, (2) stereo SEM-TEM of digest replicas and (3) whole mount stereo TEM are described. The applicability of these techniques to areas of cytoplasmic filaments organization, granule movement, and cell to cell contact organization is suggested.

Evaluation of an Emergency Department Patient Advocacy Program.

In the Patient Advocacy Program at the Adult Emergency Department of The Johns Hopkins Hospital, first year medical and health associate students provide patient teaching, crisis intervention, emotional support, assistance in patient-provider-family communication, resource referrals, information and assistance in maintaining patients' rights. The advocacy program was evaluated through a three-month trial of a Control Group, Patient Advocacy Group, Halo Group and Placebo Group, including 412 study subjects in all. It was hypothesized that patients' satisfaction, behavior and knowledge would improve significantly as a result of the advocate's intervention in this order: Patient Advocacy, Halo, Placebo and Control. Patient interviews and medical reports were used to assess the impact of patient advocacy. Results did not support the hypotheses of either improvement or the ranked order. Competition with traditional roles, identification of advocates with providers rather than patients, and placing the needs of the institution over patients were suggested as explanations for the advocacy program's failure.

Psychological characteristics of the nurse practitioner.

First, present research on the selection and characteristics of practitioners is both controversial and important. We need good answers to be helpful to those planning directions for the future of nursing. Second, we need good descriptive research indicating how applicants for different types of programs vary; how age, experience, and background factors affect the outcome of training. Third, we need multi-criteria for measuring success and effectiveness-criteria that will take into account both competence and commitment and will measure competence in a variety of ways. Fourth, we need more theory for what we are measuring and why we are measuring it. We need predictions from different personality and developmental theories. We need to contrast and combine these theoretical approaches, and we need more complex variables than we currently have. We need constructs and types rather than simple empiricism and single traits. Finally, we should not overlook the fact that the majority of nurse practitioners are women, and thus we are doing research on an interesting group at a significant time in women's history. If we are alert and responsive to what we learn about our subjects, we may also gain a deeper understanding of the lives of adult women and how they are affected by social change and changing times.

Psychological and social barriers to women in science.

Commitment and creativity in science are not merely a function of an individual's competence or excellence, but are a product of the social environment as well. Acceptance and recognition from significant other people (one's peers and other professionals), and opportunities for stimulating and challenging interaction are essential for developing a strong occupational or professional identiy, and for creating the inner sense of role competence which can lead to greater commitment and productivity in professional work. Unfortunately women, especially those who have experienced interrupted or discontinuous careers, find such opportunities and acceptance difficult to obtain.

A review of the role of social support systems in the drug use behavior of Hispanics.

In this article the authors conducted a critical review of ongoing and recently completed drug abuse studies which have examined the importance of social support systems in the drug-using behavior of Hispanics. Published and unpublished preliminary data from these studies are presented and discussed. This critical review of the research literature supports earlier findings that social support systems play an important role in preventing drug abuse among Hispanics. Specifically, this review found that familial factors, peer influences, involvement with religious institutions, and after-school activities have a powerful impact on the drug-using behaviors of Hispanic child, youth and adult drug users. The authors suggest that drug prevention and treatment programs within Hispanic communities will be more successful if they incorporate social support systems into their programs. In conclusion, the authors identify areas in which the role of social support systems in the drug-using behavior of Hispanics need further investigation.

Energy expenditure measurements in ventilated critically ill children: within- and between-day variability.

BACKGROUND: Energy expenditure measurement (EEM) by indirect calorimetry is used as a research and clinical tool in pediatric intensive care units. The aims of the study were to determine if a 30-minute EEM is representative of a 24-hour EEM (within-day variation); to determine if there is any diurnal variation during the 24-hour period of EEM; and to determine if there is a clinically significant between day variation of EEMs. METHODS: To determine within-day variation, energy expenditure was measured for a period of 24 hours for each subject (n = 11). The 24-hour period was then divided into 30-minute periods. The 30-minute means were compared with the 24-hour means. To determine between-day variation, EEMs were made daily for 30 minutes. RESULTS: In the within-day study, the overall mean percent coefficient of variation of the 30-minute measurements was 7.2% +/- 4.5%. There was no significant difference between the 30-minute means and the 24-hour means for each patient (p < .691). In 8 subjects the 30-minute means did not differ from the 24-hour mean by more than 20%. No diurnal variation was observed. The mean percent variation of between day EEM was 21% +/- 16%; the range was 1% to 69%. CONCLUSION: In critically ill ventilated children, clinically relevant within-day variations in EEM are uncommon and a single 30-minute EEM gives an acceptable guide to the level of nutrition support required. Between-day variations can, however, be large and daily EEMs are required.
