Background: Endothelial dysfunction is recognized as a major factor in the development of atherosclerosis and it has a prognostic value.

Objectives: To detect the long-term association of peripheral vascular endothelial function and clinical outcome in healthy subjects and patients with cardiovascular disease.

Methods: We prospectively assessed brachial artery flow-mediated dilation in 110 consecutive subjects (46 CVD[1] patients and 64 healthy controls), mean age 57 ± 11 years; 68 were men. After an overnight fast and discontinuation of all medications for ≥ 12 hours, percent improvement in FMD and nitroglycerin-mediated vasodilatation were assessed using high resolution ultrasound.

Results: %FMD[2] but not %NTG[3] was significantly lower in CVD patients (9.5 ± 8.0% vs. 13.5 ± 8.0%, P = 0.012) compared to healthy controls (13.4 ± 8.0% vs. 16.7 ± 11.0%, P = 0.084; respectively). In addition, an inverse correlation between %FMD and the number of traditional CVD risk factors was found among all study participants (r = -0.23, P = 0.015) and healthy controls (r = -0.23, P = 0.036). In a mean follow-up of 15 ± 2 months, the composite CVD endpoints (all-cause mortality, myocardial infarction, hospitalization for heart failure or angina pectoris, stroke, coronary artery bypass grafting and percutaneous coronary interventions) were significantly more common in subjects with FMD < 6% compared to subjects with FMD > 6% (33.3% vs. 12.1%, P < 0.03, respectively).
Conclusions: Thus, brachial artery %FMD provides important prognostic information in addition to that derived from traditional risk factor assessment

Preventive medicine is taking an increasingly central place in modern clinical practice, at least in primary care. What, if anything, does the Jewish rabbinic tradition have to say about keeping healthy? The delayed response of contemporary rabbis to the dangers of smoking, in particular, raises questions about the underlying principles that Halakhah* employs to approach health promotion. As is often the case in Halakhah, we may detect different streams of thought in the classical sources, which may be felt in the way contemporary issues are handled. Three approaches will be discussed. First, Maimonides, famous for the practical preventive approach in his medical writings, makes his philosophy clear both in his halakhic works and in his Guide for the Perplexed. For him, a healthy body is a prerequisite for a healthy soul. We must be free of physical suffering in order to be able to do the work of perfecting our souls. Second, the view that health is the reward for goodness and illness a punishment for sin as expounded or implied in the writings of Nahmanides, and of Ibn Ezra that the way to good health is to lead a good life. Third, an early midrashic** source picked up again much later by Rabbi Israel Meir Kagan (the Hafetz Hayim) gives the argument from custodianship – since the body is divine property we have a duty to look after it well. So for Maimonides there is a prior duty to keep healthy, while for Nahmanides the prior requirement is to repent of sin. For the Hafetz Hayim, keeping the body healthy is an independent duty in its own right. These then are the differences in basic approach that may affect the emphases that different rabbis today place on health maintenance and promotion.

Background: Healthcare behavior occurs within the context of the family unit. Little research has investigated the influences among adult family members regarding their use of medical care services.

Objectives: To investigate the effects of maternal attendance patterns and maternal self-assessed health status on those of adult children.

Methods: This study was a retrospective cohort, analyzing both patient records for physician visits and mailed self-administered questionnaires regarding subjective health assessment. We evaluated a unique study group of multi-generational families with free and equal access to medical services at a primary care kibbutz clinic in Israel. This enabled an exclusive focus on the association between the use of healthcare by mothers and their grown children.

Results: Controlling for the subjects' age, gender and number of chronic diagnoses, a significant association exists between the family physician visit rates of a mother and those of her grown offspring (P = 0.03). Low self-health assessment is associated with higher levels of physician utilization (P = 0.003). Maternal self-health evaluation is associated with her adult children's own self-health evaluation (odds ratio 5.9, P = 0.04) and their rates of physician utilization (one additional offspring visit per year for low maternal self-health, P = 0.02).

Conclusions: A mother’s behavior patterns measured via self-rated health status and physician visit rates serve as a proxy for maternal attitudes regarding healthcare, and these attitudes are possibly imparted to her children for life. This study provides unique evidence for a maternal health behavior effect on grown children, and enables a more complete understanding of families attending the primary care clinic.
 

Objectives: To describe how an HMO[1] used its health information technology in a way that enables its management to receive updated online information on the demands of the insured, according to their distribution throughout the country during the time of the war in Lebanon in July-August 2006.

Methods: Data were derived from the computerized medical records of Maccabi Healthcare Services – the second largest HMO in Israel, providing care to more than 1.7 million members nationwide. Data on healthcare utilization by northern members were compared to the geographic distribution of clinics.

Results: The war was characterized by the massive evacuation of citizens southwards. During this period there was an abrupt decline in the utilization of medical services by northern members in the northern region. This decline returned to normal 10 days after the ceasefire. A reciprocal increase was noted in the use of health services by citizens from the north in other regions. This increase returned to normal after the war. No such pattern was noticed during the same period in 2005.

Conclusions: Real-time surveillance of trends in consumption of health services by citizens in times of regular daily living as well as during emergencies and wars is a vital management tool for medical directors responsible for providing health services.

In Israel, updating of the National List of Health Services is performed on a yearly basis in a systematic and structured mechanism for almost a decade. The existence of such a mechanism is vital for keeping medicine up to date, since many innovative and breakthrough medical technologies continuously and frequently evolve. The 2006 update is unique in several aspects, relating both to the mechanism and to the decision-making process. In this article we describe notable issues that arose during the current process: modifications to the update mechanism, the four-phase increase in allocated resources to fund the addition of new medical technologies (including the addition of finances at the expense of the 2007 planned budget), and public funding for high-cost therapies. Finally, we discuss the impact of medical advances on healthcare costs and a suggested constant annual addition to the budget.

Background: Anti-influenza vaccination has proven cost-effective for society. In Israel, however, vaccination rates remain relatively low in comparison to other countries.

Objectives: To analyze the socioeconomic and health status factors affecting the decision to be vaccinated against flu and to compare these factors to results from other countries in order to determine which segments of the adult population should be targeted for increased coverage in influenza vaccination programs.

Methods: Our source was the 1999/2000 Health Survey of the Central Bureau of Statistics for the group aged 25 and above, comprising 16,033 individuals. We used statistical methods such as the Probit regression model to estimate the effects of socioeconomic and health status variables on the decision to get a flu shot. The variables included gender, age, marital status, education, ethnic origin, religious affiliation and housing density, as well as chronic illnesses, smoking, hospitalizations, membership in health management organizations and kibbutz membership.

Results: Our findings indicate that being a post-1990 immigrant from the former Soviet Union, living in a densely populated house, being unmarried and smoking heavily are important factors in predicting the decision not to be vaccinated. In contrast, chronic illness, previous hospitalizations, older age, and kibbutz membership have a positive effect on the decision to take the vaccine.

Conclusions: It is necessary to identify the socioeconomic and health variables marking population sectors that are less likely to be vaccinated in order to design a suitable policy to encourage vaccination.

Objectives: To assess the effects of the recently introduced co-payment for consultant specialist services on patients' utilization of these services in southern Israel.

Methods: Computerized utilization data on specialists' services for 6 months before and 6 months after initiation of co-payment were retrieved from the database of Israel's largest health management organization.

Results: A decrease of 4.5% was found in the total number of visits to Soroka Medical Center outpatient clinics and of 6.8% to community-based consultants. An increase of 20.1% was noted in the number of non-actualized visits at the outpatient clinics. A decrease of 6.2% in new visits was found in the hospital outpatient clinics and of 6.5% in community clinics. A logistic regression model showed that the residents of development towns and people aged 75+ and 12–34 were more likely not to keep a prescheduled appointment.

Conclusion: After introduction of a modest co-payment, a decrease in the total number of visits to specialists with an increase in "no-shows" was observed. The logistic regression model suggests that people of lower socioeconomic status are more likely not to keep a prescheduled appointment.

Background: Anesthesiology is a vital specialty that permits the safe and humane performance of painful procedures. Most Israeli anesthesiologist are immigrants, while only a minimal number of Israeli medical school graduates enter the specialty. Unfortunately, the supply of immigrant physicians is declining due to falling immigration rates.

Objectives: To examine the current Israeli anesthesiology workforce and project future needs.

Methods: Demographic and professional information about Israeli hospital anesthesiologists was solicited from anesthesiology department heads. Data were also gathered about the past, present and projected future growth, age distribution and birth rate of the Israeli population. Needs and demand-based analyses were used to project future anesthesiology workforce requirements.

Results: Data about 711 anesthesiologists were obtained from 30 hospital anesthesiology department heads. Eighty-seven anesthesiologists (12.2%) graduated from Israeli medical schools and 459 (64.6%) graduated from medical schools in the former Soviet Union. Among the 154 anesthesiology residents were ≤ 40 years old, and only 13 (8.4%) graduated from Israeli medical schools There are approximately 10.8 anesthesiologists per 100,000 population. Projections for 2005–2015 revealed a need for 250–300 new anesthesiologists.
Conclusions: The anesthesiology workforce is predominantly composed of immigrants. This has vast implications for the future viability of the specialty because of the continuing reduction in immigration, the lack of interest in the specialty by Israeli medical school graduates, and the projected need for many new anesthesiologists to replace retirees and to provide care to a growing and aging population
