Background: Transmission of Pseudomonas aeruginosa among cystic fibrosis patients attending health camps has been reported previously.

Objectives: To determine the transmission of P. aeruginosa among CF[1] patients during three winter camps in the Dead Sea region in southern Israel.

Methods: Three consecutive CF patient groups were studied, each of which spent 3 weeks at the camp. The patients were segragated prior to camp attendance: patients who were not colonized with P. aeruginosa constituted the first group and colonized patients made up the two additional groups. Sputum cultures were obtained upon arrival, at mid-camp and on the last day. Environmental cultures were also obtained. Patients were separated during social activities and were requested to avoid social mingling. Isolates were analyzed by antibiotics susceptibility profile and by pulsed field gel electrophoresis.

Results: Ninety isolates from 19 patients produced 28 different fingerprint patterns by PFGE[2]. Isolates from two siblings and two patients from the same clinic displayed the same fingerprint pattern. These patients were already colonized with these organisms upon arrival. Two couples were formed during the camp, but PFGE showed no transmission of organisms. All other patients' isolates displayed unique fingerprint patterns and were distinguishable from those of other attendees, and none of the P. aeruginosa-negative patients acquired P. aeruginosa during camp attendance. Environmental cultures were negative for P. aeruginosa.

Conclusions: We were unable to demonstrate cross-infection of P. aeruginosa among CF patients participating in health camps at the Dead Sea who were meticulously segregated.

Background: In the emergency department the physician is often confronted with the decision of where to hospitalize a patient presenting with chest pain and a possible acute myocardial infarction – in the cardiac care unit or in the internal medicine ward.

Objective: To characterize the clinical factors involved in the triage disposition of patients hospitalized with AMI[1] in Israel to either CCUs[2] or IMWs[3] and to determine to what extent the perceived probability of ischemia influenced the disposition decision.

Methods: During a 2 month nationwide prospective survey in the 26 CCUs and 82 of the 94 IMWs in Israel, we reviewed the charts of 1,648 patients with a discharge diagnosis of AMI. The probability of ischemia at admission was determined retrospectively by the Acute Coronary Ischemia Time-Insensitive Predictive Instrument. Co-morbidity was coded using the Index of Coexistent Diseases.

Results: The ACI-TIPI[4] score for patients admitted to CCUs or to IMWs was 76.2% and 57.7% respectively (P < 0.001). Multivariate analysis showed that young patients with a high probability of ischemia and low co-morbidity or functional impairment were more likely to be hospitalized in CCUs than in IMWs.

Conclusion: In Israel, the factors that strongly influence the initial triage disposition of patients with AMI to CCUs or IMWs are age, perceived probability of ischemia, status of co-morbid conditions and functional impairment.

Background: Little information is available on the clinical practice and implementation of guidelines in treating acute myocardial infarction patients in Israel.

Objective: To assess patient characteristics, hospital course, management, and 30 day clinical outcome of all AMI[1] patients hospitalized in Israel during a 2 month period in 2000.

Method: We conducted a prospective 2 month survey of consecutive AMI patients admitted to 82 of 96 internal medicine departments and all 26 cardiac departments operating in Israel in 2000. Data were collected uniformly by means of a hospital and 30 day follow-up form.

Results: During the survey 1,683 consecutive patients with a discharge diagnosis of AMI were included. Their mean age was 66 years; 73% were male. The electrocardiographic pattern on admission revealed ST elevation, non-ST elevation and an undetermined ECG[2] in 63%, 34% and 4% of patients respectively. Aspirin and heparin were given to 95% of patients. Beta-blockers and angiotensin-converting enzyme inhibitors were given to 76% and 65% of patients respectively. Among hospital survivors, 45% received lipid-lowering drugs. Thrombolytic therapy was administered in 28% of patients, coronary angiography was used in 45%, and 7% of patients underwent primary percutaneous coronary intervention. The 7 and 30 day mortality rates were 7% and 11% respectively.

Conclusions: This nationwide survey shows that one-third of the AMI patients in Israel are elderly (≥ 75 years). The survey suggests that clinical guidelines for the management of patients with AMI are partially implemented in the community. Data from large surveys representing the "real world" practice are of utmost importance for the evaluation of clinical guidelines, research and educational purposes.

Background: Appropriateness of hospital admission has both clinical and economic relevance, especially in light of the growing pressure for increased efficiency of health services utilization. In Israel, the number of referrals and use of the emergency room continue to rise along with an increase in hospital admissions and the number of inappropriate admis­sions. Using evaluation protocols, such as the Pediatric Appropriateness Evaluation Protocol, international studies have shown that 10-30% of hospital admissions are medically unnecessary. Inappropriate hospitalizations have an economic impact as well as medical and psychological effects on the child and the family.

Objectives: To assess the extent and characteristics of inappropriate pediatric admissions to a tertiary care facility in Israel.

Methods: We conducted a prospective study using chart review of pediatric admissions to Soroka University Medical Center on 18 randomly selected days in 1993, and evaluated the appropriateness of admissions using the PAEP.

Results: Of the 221 pediatric admissions 18% were evaluated as inappropriate. The main reason for such an evaluation was that the problem could have been managed on an ambulatory basis. Inappropriate admissions were asso­ciated with hospital stays of 2 or less days, children older than 1 year of age, Jewish children, and self-referrals to the pediatric emergency room.

Conclusions: The assessment and identification of characteristics of inappropriate hospital admissions can serve as indicators of problems in healthcare management and as a basis for improving quality of care and developing appropriate medical decision-making processes.

Background: Previous studies have documented an increased incidence of cardiac mortality and sudden death during winter months.

Objectives: To evaluate seasonal variation in sudden death in a hot climate such as the desert region of southern Israel.

Methods: We analyzed the files of 243 consecutive patients treated for out-of-hospital sudden death by the Beer Sheva Mobile Intensive Care Unit during 1989-90. Daily, monthly and seasonal incidence of sudden death was correlated with meteorological data, including temperature, heat stress, relative humidity and barometric pressure.

Results: The seasonal distribution of sudden death was 23% in spring, 21% in summer, 25% in autumn and 31% in winter (not significant). In patients with known heart disease there were more episodes of sudden death in cold weather (<15.4°C) than hot (>34.2°C) (16 vs. 3, P<0.05). Resuscitation was less successful in cold compared with hot weather (28 vs. 11, P<0.05). Of patients older than 65 years, 11 sustained sudden death when heat stress was below 12.4°C compared to 2 patients when heat stress was above 27.5°C (P=0.05).

Conclusion: Despite the warm desert climate, there were more cases of sudden death in older patients and in those with known heart disease during the winter season and on particularly cold days.
 

Background: Hallway medicine is an integral part of physicians' medical culture, but little is known about it.

Objective: To characterize the practice of hallway medicine among hospital physicians, both as providers and consumers.

Methods: We conducted a survey of 112 randomly chosen hospital physicians at the Soroka Medical Center in Beer Sheva, Israel between November 1997 and May 1998. A self-administered 39-item questionnaire was used that included sociodemographic data, the extent to which hallway medicine is practiced, and satisfaction from and attitudes to it.

Results: Of the 112 selected physicians, 111 responded (99.1%). Of these, 91 (82%) had been asked by their colleagues to provide hallway medicine. Most of them (91%) agreed because of "willingness to help," because "it's unpleasant to refuse," or "it's the acceptable thing to do." Most of the requests (72%) were unscheduled and time consuming (41% up to 10 minutes and 21% more than 20 minutes). Records were kept in only 36% of the cases and follow-up in 62%. Physicians who provided hallway medicine were also consumers of it (P<0.001), based on personal acquaintance, time saved and easy accessibility. In general, the attitude to hallway medicine was negative (54%) or ambiguous (37%). Most requests for hallway medicine were made to Israeli-trained physicians, surgeons or gynecologists, and senior physicians.

Conclusions: Hallway medicine is practiced frequently among hospital physicians. A formal organization of health care service within medical centers might provide physicians with better medical care and reduce potential ethical, medical, legal, psychosocial and economic problems.
