The objective is to assess the impact of workload on pregnancy among women physicians in public hospitals in Israel. A self-administered, cross-sectional study of pregnancies among women physicians in public hospitals was conducted. An 82-item questionnaire was mailed to women physicians in the three largest university hospitals in Israel. The questionnaire assessed demographic data, pregnancy course, perceived stress, and complications during pregnancy. Response rate was 52% (207/400). The complication rates were compared with rates in the Jewish population and expressed as mean +/- SD. Mean number of pregnancies during residency was 1.3 +/- 1.2. Mean age at the first delivery was 27 +/- 3.2 years. There was a significant difference in the rates of stillbirth (32/1000 births versus 3.7/1000, p < 0.001) and premature delivery (12.4% versus 7.6%, p = 0.0014) between women physicians and the general population. There was no significant difference in the proportion of spontaneous abortions (12.7%), pregnancy induced hypertension (3.2%), hyperemesis gravidarum (3.2%), and diabetes (1%). Seven percent of women physicians changed their specialty due to pregnancy while in residency. Our results suggest that working long hours in a stressful occupation in a hospital environment has an adverse effect on pregnancy course and is associated with increased rates of stillbirth and premature delivery.

Survey of injuries and protective gear worn by in-line skaters in public parks.

In-line skating, also known as rollerblading, has become popular as a recreational activity as well as a mode of transportation. Increased participation has been accompanied with a marked rise in major and minor injuries. The objective of this study was to survey active in-line skaters and to describe their demographic features, formal training, protective gear used, and a history of incurred injuries. A questionnaire was distributed to randomly selected in-line skaters in a large public park in New York City. Of the 223 skaters who responded, 128 were male and 95 were female. Ages ranged from 12 to 64 (mean, 29) yr. Some kind of injury was reported by 87 (39%) of the participants. The majority of those injuries occurred when the skaters were beginners (46). Skin abrasions and musculoligamentous injuries were the most common. Only 15 (17.2%) sought medical treatment, and of these, 5 were treated for fractures: 3 at the wrist and 1 each at the ankle and knee. The knee was the most commonly injured part of the body (24.7%), followed by the elbow and wrist. Approximately 5% of all injuries involved the head. Many skaters did not wear helmets or knee pads, even though they owned this equipment. There was a strong preference for wearing wrist pads, either alone or with other protective gear. This suggests that skaters have learned that the wrist is particularly vulnerable to serious injury and should be protected.

A simplified testing system to evaluate performance after transplantation of human skin preserved in glycerol or in liquid nitrogen.

We have designed and tested a mouse recipient model for evaluation and direct comparison of skin-preservation procedures. Glycerolized skin was compared with cryopreserved and fresh cadaveric skin. Human skin samples were grafted on Balb/c mice, and primary take was evaluated after 4 and 7 days. The results demonstrate that although all grafted specimens were initially accepted as indicated by gross observations, histologic differences were evident and significant. Cryopreserved skin grafts performed better than did glycerolized skin even after a transplantation period as short as 4 days; this difference became even more pronounced after 7 days. Both methods of preservation provided a less successful product than did fresh viable cadaveric skin. However, for very short periods of grafting the performance of glycerolized skin might be considered adequate (79% compared with cryopreserved). Because the present study used an immunocompetent xenogeneic model, it is possible that the period of adequate allogeneic grafting will be prolonged in patients who are immunosuppressed. The present model is simple to use, requires a minimum of maintenance and expertise, and has inherent clinical relevance, because it is concerned primarily with the clinical performance of the skin. Thus it may be used as a quality control test for banked skin.

Transplantation performance of human skin cryopreserved by programmed or stepwise freezing and stored at -80 degrees C or -180 degrees C.

We developed a mouse recipient model that was used to evaluate and compare four cryopreservation procedures for human cadaveric skin stored for two time periods. Skin specimens were identically processed and preserved by programmed (1 degree C/min), or stepwise freezing, and stored at -180 degrees C or -80 degrees C for periods of 1 month and 6 to 10 months. Samples were grafted on Balb/c mice, and primary take was evaluated after 7 days. The results indicate that although all grafted specimens were initially accepted, as indicated by gross observations, histologic differences were evident and significant. The study groups were analyzed for the effect of method and skin sample variety; the effect of freezing procedure and temperature level; time effect (storage period); and advantage of method 1 (programmed freezing at -180 degrees C) over the other methods. The significance (p value) was determined for separate histologic criteria and average skin score or quality. The overall results indicate that average score of skin preserved by method 1 is highest for both storage periods. This method has an almost significant advantage (p = 0.057) over the others on quality of skin stored for 1 month, and a highly significant advantage (p = 0.007) on graft adherence of skin stored for 6 to 10 months. The effect of method and samples variety on the separate histologic criteria and average score of skin is not always significant. However, an interaction factor (between method and samples) has a highly significant effect (p < 0.001) on almost all of the histologic criteria and average skin score. The effects of freezing method is significant only on average skin score, for 1 month of storage; whereas temperature effect is seldom significant. Evaluating the effects of time, samples, and the interaction factor (between time and samples) indicated that the interaction factor is highly significant (p < 0.001). Time and samples effects are rarely significant. Thus the quality of the final product-the cryopreserved skin-is determined by many factors, and quite often they interact. Highly significant is the combined effect, or interaction factor, of sample variability with method of cryopreservation or with storage period.

Israel--a health system in transition.

Israeli health reform, implemented after many failed attempts throughout the years, represents an attempt to solve problems of politicization, dissatisfaction, unclear roles of government and public organizations, and lack of financial accountability, while maintaining a high quality and universally accessible health system. Despite many favorable aspects, including high quality medical care, near universal insurance coverage, and high availability of services, the health system has attracted criticism since its earliest days. Israel's experience with health reform, based on a version of managed competition, is of interest to other countries considering similar policy decisions.

Preadmission screening of patients scheduled for hip and knee replacement: impact on length of stay.

OBJECTIVE: An evaluation of the impact of a social work preadmission program on length of stay (LOS) of orthopedic patients undergoing elective total hip or total knee replacement surgeries (under diagnosis-related groups [DRGs]) at the Hadassah Ein-Kerem Hospital in Jerusalem is Israel. INTERVENTION: The social work interventions included preadmission psychosocial evaluation and preliminary discharge planning, coordination of nursing and physiotherapy evaluations, ensuring completion of all medical tests prior to admission, and additional psychosocial follow-up during hospitalization to carry out the original discharge plan or prepare alternatives. PATIENTS: The intervention patients were divided into two groups in order to see changes over time: May through December 1994 (n = 48), and January through December 1995 (n = 81). The comparison groups included patients operated on at the same hospital during 1993 (n = 51) and during January through April 1994 (n = 21) and at the Hadassah Mount Scopus Hospital during the same time periods. Patients in the comparison groups received usual social work intervention, as necessary, only after hospitalization. RESULTS: Mean LOS was reduced significantly in the intervention patient groups, as compared to the preintervention patient groups in the same hospital, from 14.2 days (standard deviation [SD], 4.7) in 1993 and 14.7 (SD, 5.1) in January through April 1994 to 10.9 (SD, 3.0) in May through December 1994 and to 9.1 (SD, 2.8) in 1995 (P < .01). Length of stay also was reduced in the comparison hospital, but by 1995 was longer than in the intervention patients. No differences in LOS by gender, age, or marital status were found. Length of stay was significantly longer for those undergoing total hip replacement as compared to those undergoing total knee replacement in all the groups. CONCLUSIONS: Preadmission screening and case management by a social worker can contribute to the efforts to decrease LOS of orthopedic patients by early multidisciplinary evaluations, discharge planning, and coordination of services.

Measurements of electromagnetic fields radiated from communication equipment and of environmental electromagnetic noise: impact on the use of communication equipment within the hospital.

The increasing use of all types of cellular telephones requires the formulation of new standards to ensure the immunity of electronic medical equipment to electromagnetic radiation. It will be many years before all hospital medical equipment conforms to new and higher standards. Until that time, the medical, security, maintenance, and other staff will need to be ever vigilant regarding restrictions on the use of wireless equipment within the hospital, to prevent potential danger to the lives of the patients. A comprehensive hospital policy must be formulated to reduce risks to patients from equipment susceptible to electromagnetic interference (EMI). Such an aim should address the following needs: To devise a uniform policy for the instruction of hospital staff, visitors, and patients, thereby reducing confusion regarding the use of cellular telephones, beepers, and portable transceivers. To implement a policy that avoids unwarranted restrictions but does not ignore statistical evidence regarding potential EMI problems. To allow comparison, with other clinical facilities, of the benefits derived from such a policy.
