Background: The increasing utilization of general internal medicine hospital wards in Israel during the last decade is a source of concern for health policy makers.

Objectives: To report on the distribution of selected main and secondary diagnoses among GIM inpatients, and to estimate the proportion of disorders for which appropriate care in the community will reduce the need for hospital admissions and re-admissions.

Methods: Data from the Health Information and Computer Services of the Israel Ministry of Health (national hospitalization database) for a one year period were analyzed by distribution of diagnostic entities (ICD-9-CM) in GIM and in medical subspecialty wards.

Results: Of the 313,824 discharges from hospital divisions of medicine in 1995, 256,956 (81.9%) were from GIM and 56,868 (18.1%) from specialty wards. Main and secondary discharge diagnoses were available for 188,807 GIM and 35,992 specialty patients. Of all main diagnoses in GIM wards, 27% were coded as "general or systemic symptoms and signs" or as "abnormal laboratory or ill defined manifestations" (ICD-9-CM codes 780-799, 276,277), and heart diseases comprised another 27%. The remaining main diagnoses covered almost all medical conditions. The combined proportion of "ambulatory care sensitive hospital admissions" (bronchial asthma, hypertension, congestive heart failure, chronic obstructive pulmonary disease, diabetes) constituted 12% of all main diagnoses in GIM, and respiratory symptoms or signs comprised another 11%. A by-product of this analysis was an insight into the experience of undergraduate medical students in GIM.

Conclusions: Assuming that 12-75% of admissions for "ambulatory care sensitive disorders" are preventable, an improved review before hospital discharge and a closer outpatient follow-up may reduce the load on GIM wards by 1-17%. This wide range justifies controlled trials to determine the effect of improved community care on hospital utilization. GIM wards offer valuable learning opportunities, but they cannot be a substitute for primary care clinics. The unexplained high proportion of GIM inpatients who were discharged with an unspecified main diagnosis could be detrimental for the accuracy of hospitalization statistics, and justifies investigation by chart audits into physicians' habits of documentation.

Background: Cefuroxime is a second-generation cephalosporin antibiotic used widely for the treatment of various infections.

Objectives: To assess the appropriateness of cefuroxime usage as well as the long-term impact of re-feeding the results to prescribing physicians.

Methods: Drug utilization evaluation involved three data-collecting periods, each comprising 6 weeks, during which all patients receiving cefuroxime were evaluated. Results of phase I were distributed to all physicians in a newsletter and departmental lectures; phase II was announced and conducted 6 months later. An identical phase III was unannounced and conducted one year after phase II. The study included all patients receiving cefuroxime during the three phases. The main outcome measure was appropriateness of initiation, and continuation beyond 3 days, of empirical treatment. Appropriateness was determined according to a prepared list of indications based on the literature and the hospital's protocols.

Results: Cefuroxime was initiated appropriately in 104 of 134 patients (78%) in phase I, in 85 of 100 (85%) in phase II, and in 93 of 100 (93%) in phase III (P<0.001). Cefuroxime was continued appropriately after 3 days in 58/134 (43%), 57/100 (57%) and 70/100 (70%) respectively (P<0.001). The total number of appropriate treatment days out of all treatment days increased from 516 of 635 (81%) in phase I, to 450 of 510 (88%) in phase II, to 485 of 509 (95%) in phase III (P<0.001). The principal reason for cefuroxime usage was community-acquired respiratory tract infection.

Conclusion: Drug utilization evaluation may provide valuable data on the usage of a particular drug. This information, once re-fed to physicians, may improve utilization of the particular drug. This positive effect may be prolonged beyond the immediate period of observation.

Background: Bronchiolitis caused by respiratory syncytial virus is one of the major causes of hospitalization in young children, especially during the winter.  Recent evidence has shown that pharmacological treatment, especially nebulized epinephrine, in addition to the traditional supportive treatment, can alleviate symptoms and shorten hospitalization, but this approach is not yet widespread.

Objectives: To determine whether the management of bronchiolitis in Israel is moving toward a stronger emphasis on pharmacological care.

Methods: A questionnaire on the diagnosis and management of bronchiolitis was completed by 27 heads of pediatric departments throughout Israel.  The questionnaire dealt with the frequency of usage of diagnostic and selected therapeutic procedures.

Results: Chest X-ray and arterial blood gases are commonly used as a diagnostic aid in more than 75% of the departments, and antibiotics are prescribed routinely in 24%.  Corticosteroids are still in use: 48% use systemic steroids, and 19% nebulized steroids.  Nebulized epinephrine is used in 22% of the departments, while nebulized beta-agonists are used frequently in two-thirds of the departments.

Conclusions: Despite convincing data that beta-agonists and steroids have no positive effect on the outcome of bronchiolitis on the one hand, and that nebulized epinephrine has advantages in children on the other, we found significant use of the former two agents and sparse use of the latter.  Greater awareness is needed among pediatricians, and measures should be introduced to incorporate the new recommendations, with further study of the effect of the old and new drugs on bronchiolitis.

 

Objectives: To analyze the factors that influence the success of physicians in the ATLS®¹ written tests.

Methods: A retrospective study was conducted of 4,475 physicians participating in the Israeli ATLS® training program between 1990 and 1996. Several variables in the records of these physicians were related to their success or failure in the final written examination of the course.

Results: Age, the region of medical schooling, and the medical specialty were found to significantly influence the successful completion of the ATLS® course.

Conclusions: Physicians younger than 45 years of age or with a surgical specialty are more likely to graduate the ATLS® course. The success rate could be improved if the program’s text and questionnaires were translated into Hebrew.

 Background:  Pulmonary alveolar proteinosis is a rare disease in which a surfactant-like phospholipid-rich protein accumulates in the lungs. The disease is amenable to effective therapy by total lung lavage.       

Objectives: To investigate the prevalence, ethnic distribution and course of PAP  in Israel.

Methods: A countrywide survey was conducted during which pulmonologists were questioned about patients with PAP. The patients were examined and their charts, radiological images, pathological slides and physiological data were reviewed.

Results: The survey yielded 15 patients (8 females) during the period 1976–98 (14 in the last decade), giving a prevalence of 3.7x10⁶ and an incidence of 0.36x10⁶/year.

Mean age of the patients was 33±13 years (range 0.5–46 years). Seven patients were North African (two were siblings), four were from Iraq and two were Arabs; there was only one Ashkenazi Jew (a child). Symptoms at the onset were dyspnea and chest pain. Spontaneous remission occurred in at least 3 patients, and 10 patients required 1–4 bronchoalveolar lavage treatments. The subjective and physiological response was favorable, but there was less consistent radiological improvement.

Conclusion: The prevalence of PAP in Israel is approximately 3.7x10⁶. Most cases occurred in Jews who had immigrated from North Africa or Iraq, and two were siblings. The prevalence among the Arab population appears to be similar. This clustering suggests the existence of a genetic predisposition. The course of the disease appears to be similar to that reported elsewhere.
