[Direct percutaneous transluminal coronary angioplasty].

Early reperfusion in acute myocardial infarction (AMI) effectively reduces mortality. Direct. percutaneous. transluminal coronary angioplasty (PTCA) is a recognized alternative to intravenous thrombolytic therapy in early AMI. Of 289 PTCAs performed during a year, 29 (10%) were direct PTCAs. Indications for direct PTCA in 21 patients (72%) were large infarcts, and in 8 (28%) cardiogenic shock. The left anterior descending artery was involved in 15 patients (52%), the right coronary artery in 10 (34%), the left circumflex in 3 (10%), and the left main artery in 1 (3%). Satisfactory opening of the occlusion was achieved in 26 (90%); there was partial success in 2 (7%) and failure in 1 (3%). 4 patients required stent deployment for treatment of dissection. There was no major complication. A patient in whom success was only partial, and the one in whom PTCA failed, were sent for operation. These data do not differ from our success rate in elective PTCA. It is concluded that direct PTCA is a safe procedure with a high rate of successful reperfusion in AMI.

Compassionate-empathic physicians: personality traits and social-organizational factors that enhance or inhibit this behavior pattern.

Compassionate-empathic physicians (CEPs) are desired by patients, but rarely found in medical settings. The purpose of this study was to promote our understanding of this gap by determining personal characteristics that distinguish CEPs from other physicians, and organizational factors that might enhance or inhibit physicians' compassionate-empathic behavior (CEB). In the first stage of the study, three groups of physicians who differed in their compassionate-empathic pattern of behavior toward patients were identified by a sociometric questionnaire distributed to 324 physicians in a general hospital. In the second stage, almost all of these physicians (N = 308) were asked to fill out a self administered structured questionnaire, and 214 (69.5%) responded. Comparisons among the three groups show that the physicians identified as CEPs, more than other physicians, are younger, have fewer years in medical practice, and score higher on pro-social, non-stereotypic attitudes toward patients and on empathy measures. Their self-esteem is, however, similar to that of the non-CEPs. The CEPs express similar levels of satisfaction with work on most dimensions, but they report more emotional exhaustion (burnout) than other physicians. A consensus among all physicians was found with regard to two rank orders: (a) the important qualities for being "a good physician"; and (b) the important qualities for being promoted in the hospital. However, while empathic behavior was considered the most important quality for being "a good physician", it was ranked as the least important for being promoted in the hospital. The conclusions can serve as a scientific base for improving methods of selection of medical students, and for re-evaluating the existent criteria for promoting medical staff in general hospitals.

Behavior, attitudes, and expectations regarding the use of life-sustaining treatments among physicians in Israel: an exploratory study.

The use of life-sustaining treatments (LST) for prolonging lives of terminally ill patients without being able to improve the quality of life is a source of ethical, medical, economic and legal dilemmas for physicians. Although physicians in all Western countries face these dilemmas, they are unique in each society due to the special combination of its dominant religion, and its priorities regarding social values and legislation. This paper presents opinions, attitudes, expectations and behavior regarding the use of LST among 25 physicians attached to one teaching hospital in Israel. The data, which was collected by in-depth, semi-structured interviews, indicate that all of the physicians agree that life does not always have to be artificially prolonged. The general message that the physicians conveyed was that they deal quite effectively with these issues. They are not at all bothered by economic considerations and found ways to deal with the legal, ethical and medical dilemmas. It is suggested that in Israel the core issue is not the current law, but lack of communication among physicians and between physicians and patients/families. The relevance of the dominant model of the doctor-patient relationship and applications for medical education and practice are discussed. A list of hypotheses derived from this exploratory study for future intra-societal and inter-societal research is presented.

Relation between shortness of breath, left ventricular end diastolic pressure and severity of coronary artery disease.

The relation of shortness of breath to left ventricular end diastolic pressure and the severity of coronary artery disease was evaluated in 146 patients with normal segmental and global left ventricular systolic performance. None had chronic lung disease, cardiomyopathy, previous myocardial infarction, uncontrolled hypertension or unstable angina pectoris. A strong relationship was found between shortness of breath and elevated left ventricular end diastolic pressure, and a borderline relationship with the severity of coronary disease. Shortness of breath as a clinical symptom indicates diastolic dysfunction in this selected group of patients.

Angiographic follow-up of coronary artery ectasia.

Of 1,125 patients catheterized over a period of 8 years, 68 (6%) had coronary ectasia. Twenty-five of them were catheterized at least twice and constituted the study group. The time between the first and last catheterization ranged from 2 to 8 years (mean +/- SD = 4.2 +/- 1.6). Coronary ectasia was more frequent in males (88%). The frequency of involvement was: the right coronary (47%), the left circumflex (30%), the left anterior descending (21%) and the left main arteries (2%). Proximal segments were most frequently involved (48%). Diffuse involvement was found in 29%. Severity of ectasia progressed in 6 segments (14%) and 2 new ectatic segments appeared over the follow-up period. During that period, 2 patients had myocardial infarction, 1 of them due to a total occlusion of an ectatic segment. There were no deaths. In conclusion, coronary ectasia has a relatively benign course.

[AIDS-related knowledge, behavior and attitudes of workers in Israel].

Control of the AIDS pandemic depends largely on the success of educational programs designed to persuade the population at risk to use currently recommended methods of prevention. In Israel there are no regular national surveys on the health-related behavior of the population. The consequent lack of reliable data makes it difficult both to develop and to evaluate AIDS-related educational programs. A survey was therefore conducted among 536 employees of 3 workplaces in Dec. 1992, using anonymous questionnaires. The level of general knowledge of the disease was good, although in selected areas there were deficiencies: more than 20% of the men and 40% of the women believed that AIDS can be contracted through the use of public toilets. More than 50% of the subjects indicated that they would like more information on the disease, and believe that insufficient education is given youth regarding the use of the condom. Women tended to be more worried than men about the possibility of contracting AIDS, and were more likely to adopt preventive behavior and educate their children in this regard. These findings indicate the need to design separate educational programs for men and women. Further on-going surveys in representative samples of the general population are urgently needed to monitor trends in AIDS-related knowledge, attitudes and behavior.

Left ventricular performance in patients with normal coronary arteries: hemodynamic characteristics and clinical follow-up.

Of 111 patients with normal coronary angiograms, 68 patients had elevated left-ventricular end diastolic pressure and 'low-normal' ejection fraction (Group I) while the other 43 patients had normal left ventricular end diastolic pressure and 'high normal' ejection fractions (Group II). Although the number of patients was too small for meaningful statistical analysis, systematically a higher percentage of patients with diabetes mellitus, hypertension, hypercholesterolemia and smoking history was found in Group I. In contrast to the patients in Group II, patients in Group I tended to have more angina and ischemic events.

Measuring patient satisfaction in primary care: a joint project of community representatives, clinic staff members and a social scientist.

We describe the process of planning and developing a questionnaire and conducting a patient satisfaction survey in a neighbourhood clinic in Beer-Sheva, Israel. The project was conducted by the clinic staff members, patient representatives and a medical sociologist. The satisfaction survey was conducted in patients' homes, with a 67% response rate. General satisfaction and satisfaction with specific components of service are described. Patient satisfaction was higher among men than among women, and negatively correlated with family size. The strongest predictor of general satisfaction was satisfaction with physicians' services. Implications of the survey results were decided upon by active collaboration between the clinic staff and the patient representatives. The inferences drawn from the patients' replies and the changes introduced as a result of them, are discussed. Health care consumers should be active participants in carrying out surveys of satisfaction on a regular basis.

The role of age and an expanded Health Belief Model in predicting skin cancer protective behavior.

Skin cancer (SC), the most common form of cancer in the US, with a rapidly growing incidence, has become a target for health education. Sun exposure protective behavior (SEPB) is currently believed to be the best means to prevent it. Focusing on age differences, this paper applies an expansion of the Health Belief Model (HBM) to the prediction of engagement in SC protective behaviors in four age-groups, following an intervention program. It is based on data collected by a structured questionnaire completed by 509 members of four kibbutzim in Israel. The results indicate that the proposed model explains the SC-related protective behaviors of the older age-groups (45+) much better than that of the younger groups (15-44). The older age-groups are also more likely to change risky behavior following the intervention. The youngest age-group (15-29), although being highest at risk for SC due to sun exposure habits, is least likely to change them and least likely to participate in the intervention. Beliefs about sun tanning, sun exposure habits (barriers) and degree of exposure to the intervention are the best predictors of the likelihood to engage in SEPB in the younger age-groups, while among the older groups the best predictors are the value of health and appearance. These findings suggest that health education programs should develop different messages for different age-groups. Regarding SC, it seems especially important to focus prevention efforts on adolescents and young adults by recruiting the beauty and fashion industries as well as legislation. The merits of age group analyses in the research of health behavior are discussed.

Coping with the Gulf war: subculture differences among ischemic heart disease patients in Israel.

The purpose of this study was to assess short term effects of the Gulf war on ischemic heart disease patients of different ethnic origin. Three dimensions of patients' reactions to the war situation were studied: psychological, physical and behavioral. The study first focused on changes in patients' responses on these dimensions over three stages of the war, differentiated according to degree of threat. Second, differences stemming from ethnic origin were examined among patients who live in the same geographical region, use the same health services and were exposed to the same threatening life event. One hundred ischemic heart disease patients were interviewed while waiting in outpatient hospital clinics for a regular examination at the end of the war. The results of intrapersonal comparisons showed that the intensity of responses, as expected, increased significantly on the three dimensions from the week before the war started to the first week of the war, which was the most stressful period for Israelis. During the last week of the war, however, when stress was significantly reduced, the expected change was found primarily with regard to psychologic responses. That is, worries were significantly reduced, but no significant reduction in frequency of anginal pain and in drug consumption followed, indicating differences in the adjustment process on the psychologic and physical levels. Subcultural differences were found in the studied responses: Patients of Asian or North African countries of origin reported having more frequent anginal pains, and consuming more drugs than patients from Western countries.(ABSTRACT TRUNCATED AT 250 WORDS)

Coping with recent life events: the interplay of personal and collective resources.

The importance of personal and collective resources in coping with recent life events was studied among 230 kibbutz members. The sense of coherence, a global life orientation that detects the ability to avoid stressors and to choose appropriate coping strategies and resources, represented personal resources. Collective resources, embedded in the social system to which one belongs, were measured by membership in a religious kibbutz, the kibbutz being viewed as a powerful, collective-coping resource by itself. Physical well-being, psychological distress, and functional limitations were used as outcome measures. Both types of resources have a salutogenic effect, but sense of coherence appears to be a better resource for avoiding the effect of recent life events and for moderating psychological distress and functional limitation after experiencing such events. The two types of resources have no additive effect, nor do they compensate for each other. Only one significant interaction was found, suggesting that the combination of the two resources is useful in avoiding functional limitation. It is also suggested that collective resources have a slight positive effect on personal resources, which, in turn, take over and become most valuable in coping with recent life events. When stress affects social functioning, these same personal resources facilitate the mobilization of whatever collective resources are available.

Abnormal thallium stress test and normal coronary angiograms: catheterization and clinical characteristics.

Left ventricular end-diastolic pressure at rest, left ventricular ejection fraction, thallium segmental abnormalities, as well as sex, age and presence of diabetes mellitus, hypertension, hypercholesterolemia and smoking excess were analyzed in 40 patients with abnormal thallium stress test and normal coronary angiograms. Of these patients, 25 had elevated left ventricular end-diastolic pressure and "low normal" ejection fraction (group 1), while the other 15 had normal left ventricular end-diastolic pressure and "high normal" ejection fraction (group 2). The left ventricular end-diastolic pressure was 18.1 +/- 4.5 mm Hg in group 1 vs. 8.5 +/- 2.4 mm Hg in group 2 (P < 0.000). The ejection fraction was 57.6 +/- 8.3% in group 1 vs. 63.9 +/- 9.1% in group 2 (P < 0.05). There was no difference between the groups in relation to the abnormal segment on thallium stress tests, aged and sex. Although the number of patients was too small for meaningful statistical analysis, most of the patients with diabetes mellitus, hypertension, hypercholesterolemia or smoking history were in group 1. Thus, the patient population with abnormal results on radionuclide exercise tests and angiographically normal coronary arteries probably comprises two groups: a) patients with decreased diastolic and relatively decreased systolic performances which might reflect coronary flow disturbances, and b) patients with normal diastolic and systolic performances, probably reflecting "true false positive thallium stress test".

Life events, sense of coherence and health: gender differences on the kibbutz.

The effects of recently experienced life events (RLE) and of a personal coping resource--the sense of coherence (SOC)--on the health of men and women were investigated among members of two small and cohesive communities--two kibbutzim in Israel (n = 230). Results of analyses lend support to previous findings about the negative effects of life events on health, and to Antonovsky's theory about the positive influence of SOC on health. Separate analyses for men and women, however, show that while RLEs negatively affect women's health, SOC has no significant counterbalancing effect on their health. Among men, an opposite pattern is found; their health is not affected by RLE, but is significantly affected by their SOC. Our findings lead to the conclusion that men and women are differentially affected by stressors and make different use of their coping resources. These findings should be taken into consideration in further research on stress, coping and health.

Gender differences in the utilization of emergency department services.

Some of the suggested explanations of the well documented gender morbidity differences imply that these are not 'real' but the result of women's tendency to perceive and report more symptoms, to magnify symptom severity, and to seek help. To contribute to this debate, gender differences in utilization of a general hospital emergency department (ED), often used as a primary care service and for mild conditions, were studied. Data were collected from the general ED admissions registry for 6815 patients. In our data strikingly more men than women visited the ED during the period studied; generally, the same proportion of men and women were self-referred patients; and similar rates of both sexes were hospitalized regardless of type of referral. Thus, these findings suggest that, at least among ED patients, there is no gender differential in symptoms perception, evaluation, or presentation. Indications for these were somewhat found among young patients (aged 17-24) only. Alternatively, the findings with regard to this age group could reflect professional gender stereotyping at the primary care level.

Social class differences in coping with a physicians' strike in Israel.

The 1983 physicians' strike in Israel lasted 118 days. Striking physicians established alternative medical care centers (ACC) providing primary and specialized medical care on a fee for service basis. This contrasted with the usual pre-paid health insurance system, and provides an interesting natural experiment in health care services. Hospital emergency rooms remained open during the strike. Thus, primary medical care was available in these two settings. This paper compares people of different educational levels as they experienced and adapted to this strike with regard to their expressed need for physicians, their health behavior and outcomes in terms of patterns of utilization of the two services, financial expenses, satisfaction with the ACC's and perceived damage to health caused by the strike. The data were extracted from 719 self-administered questionnaires which were distributed in 14 primary care clinics and among university employees. The results show that the groups with lower levels of education, as compared to groups with higher education levels, reported more need for physicians' care and more damage to health. They were, however, less critical of the parties involved in the strike. When urgent need was reported, all respondents behaved similarly; however, people of lower social classes reported less satisfaction and perceived more damage. In non-urgent need conditions, although lower class respondents had higher utilization rates and higher expenses, they achieved no better results than the higher classes. It is suggested that due to a relative lack of psychological, social and financial resources, people of lower socio-economic classes cope less effectively with sudden changes in the provision of health services.

Emergency department utilization: a comparative analysis of older-adults, old and old-old patients.

A comparative analysis of Emergency Department (ED) utilization by 2936 older-adults, old, and old-old patients was conducted in the only hospital available for residents of a vast geographical region. All patients (45+) who arrived at the ED during the first week of every even month from September 1986 to August 1987 were selected for the study. No significant differences were found among the three groups with regard to sociodemographic characteristics other than age. Data showed that the old-old use the ED approximately twice as much as the old and the older-adults; they also use the ED more often than the two other groups during the winter season. These two findings indicate the utility of viewing the old-old not only as a part of the elderly population, but also as a unique risk group. Hospitalization rates present a different pattern: they double in each age group moving from the youngest to the oldest. Complaints of an internal medicine nature are more often presented by the two groups of the elderly in comparison to the older-adults, and are followed by more frequent hospitalizations in internal medicine wards. Such findings have practical implications, and should be taken into consideration by policymakers.

Emergency department utilization by two subcultures in the same geographical region.

An exploratory study of emergency department (ED) utilization, comparing Israeli adult Jews and Bedouin Arabs was conducted. The data interpretation derived from the premise that health services utilization reflects not only morbidity patterns but characteristics of both subcultures and the structure of health services. The Bedouins in the study are a Moslem traditional society going through a rapid process of urbanization and modernization, with a relative deficiency in primary health services. Data were collected from the general ED admissions registry. Patients (17+) who arrived at the ED during the first week of every even month of one calendar year were selected for this study (6815 Jews and 583 Bedouins). The findings indicate that, in general Bedouins use the ED significantly less than Jews. They adjust to the structure of the ED services and use them, more than Jews, as a primary service. Yet, the hospitalization rates of the two populations are similar. In both subcultures the pattern of gender differences changes after the age of 45. The change, however, is in the opposite direction. Differences in ED usage among Bedouin age-sex groups are discussed in terms of changes in social status during a period of socio-cultural transition.
