Objective: To gain an insight into the forces behind these changes, we compared the trends in hospital utilization in Israel with those in 21 developed countries with available data.

Materials and Methods: Our data were derived from The "Hospitals and Day Care Units, 1995" report by the Health Information and Computer Services of the Israel Ministry of Health, and the Organization for Economic Cooperation and Development Health Data, 98. We examined the numbers of acute care hospital beds, of patients on dialysis and of doctors' consultations, health expenditures and age structure of the population in 1995 or closest year with available data, as well as changes in DRs, HDs and ALOS between 1976 and 1995.

Results: In Israel the DRs increased from 130 in 1976 to 177 in 1995 (36%), HDs declined from 992 to 818 (18%), and ALOS declined from 7.60 to 4.51 days (41%). Relative to other countries, in 1995 Israel had the lowest ALOS; low HDs similar to those in the UK, Portugal, Spain, the USA and Sweden; and intermediate DRs similar to those in Belgium, Germany, Sweden and Australia. The number of acute care beds per 1,000 population was directly related to HDs (r=0.954, P=0.000) and to DRs (r=0.419, P=0.052). Health expenditures (% of the gross national product) correlated with the number of patients on dialysis per 1,000,000 population (r=0.743, P=0.000). Between 1976 and 1995, HDs and ALOS declined in most countries, however the trends in DRs varied from an increase by 119% in the UK to a decline by 29% in Canada.

Conclusions and hypotheses: The increase in DRs in Israel from 1976 to 1995 was shared by many but not all countries. This variability may be related to differences in trends in local practice norms and in available hospital beds. If the number of patients on dialysis is a valid index for use of expensive treatment modalities, the correlation of health expenditures with the number of patients on dialysis suggests that the use of expensive technology is a more important determinant of health care costs than the age of the population or hospital utilization. Since the use of expensive technology is highest during the first few days in hospital, decisions about health care policy should consider the possibility that the savings incurred by a further decline in HDs and ALOS may be offset by a possible increase in per diem hospital costs and in health care expenditures after discharge from hospital.

Background: With market failures characterizing the health care sector, societies are continuously searching for ways to achieve an efficient and fair allocation of resources. A natural source of opinion on the desired allocation of health resources is the public. In fact, several governments have recently involved the general public in decisions about resource allocation in their health systems.

Objectives: To investigate the views of the Israeli Jewish public aged 45-75 on horizontal equity in medical care; specifically, the characteristics (including a lottery) for determining which of two individuals with similar medical need should be treated first, against a background of limited resources.

Methods: A sample of 2,030 individuals was chosen to represent a population of about 800,000 urban Jewish Israelis aged 45–75. Data were collected in face-to-face full sit-down interviews by trained interviewers between October 1993 and February 1994.

Results: The three most preferred prioritizers were chances of recovery, number of dependants, and young age. Random prioritization was preferred by only 8% of the population. Age, level of education and religiosity were the main characteristics associated with the choice.

Conclusions: The Israeli adult public does not favor strict horizontal equity in health care. As in other social programs, “equals” were defined in a multi-criteria manner, based on both medical need and other personal characteristics. The preferred prioritizers seem to reflect universal tastes and cast doubt on the traditional distinction between efficiency and equity and between horizontal and vertical equity when applied to health care.
 

Background: Data regarding the epidemiology of secondary pulmonary hypertension are scanty.

Objectives: To describe the spectrum and relative incidence of background diseases in patients with significant secondary PHT.

Methods: We identified 671 patients with systolic pulmonary artery pressure of 45 mm Hg or more from the database of the echocardiographic laboratory. Their background diseases were recorded and classified into three subgroups: cardiac, pulmonary and pulmonary vascular disease without pulmonary parenchymal disease. Age at the first echocardiographic study, gender and systolic PAP values were recorded. Data between the three subgroups were compared.

Results: The mean age of the patients was 6515 years, mean systolic PAP 6114 mm Hg and female:male ratio 1.21:1. At the time of diagnosis 85% of the patients were older than 50. PHT was secondary to cardiac disease in 579 patients (86.3%), to PVD without PPD in 54 patients (8%) and to PPD in only 38 patients (5.7%). Mean age and mean systolic PAP did not differ significantly among the three subgroups. There was a significantly higher female: male ratio in patients with PVD without PPD compared with cardiac or pulmonary diseases (1.7:1 vs. 1.2:1 and 1.7 vs. 0.8:1 respectively, P0.05).

Conclusions: The majority of patients with significant PHT are elderly with heart disease. PVD without PPD and chronic PPD are a relatively uncommon cause of significant PHT. Since the diagnosis of PHT is of clinical significance and sometimes merits different therapeutic interventions, we recommend screening by Doppler echocardiography for patients with high risk background diseases.

Background: Carbohydrate malabsorption of lactose, fructose and sorbitol has already been described in normal volunteers and in patients with functional bowel complaints including irritable bowel syndrome. Elimination of the offending sugar(s) should result in clinical improvement.

Objective: To examine the importance of carbohydrate malabsorption in outpatients previously diagnosed as having functional bowel disorders, and to estimate the degree of clinical improvement following dietary restriction of the malabsorbed sugar(s).

Methods: A cohort of 239 patients defined as functional bowel complaints was divided into a group of 94 patients who met the Rome criteria for irritable bowel syndrome and a second group of 145 patients who did not fulfill these criteria and were defined as functional complaints. Lactose (18 g), fructose (25 g) and a mixture of fructose (25 g) plus sorbitol (5 g) solutions were administered at weekly intervals. End-expiratory hydrogen and methane breath samples were collected at 30 minute intervals for 4 hours. Incomplete absorption was defined as an increment in breath hydrogen of at least 20 ppm, or its equivalent in methane of at least 5 ppm. All patients received a diet without the offending sugar(s) for one month.

Results: Only 7% of patients with IBS and 8% of patients with FC absorbed all three sugars normally. The frequency of isolated lactose malabsorption was 16% and 12% respectively. The association of lactose and fructose-sorbitol malabsorption occurred in 61% of both patient groups. The frequency of sugar malabsorption among patients in both groups was 78% for lactose malabsorption (IBS 82%, FC 75%), 44% for fructose malabsorption and 73% for fructose-sorbitol malabsorption (IBS 70%, FC 75%). A marked improvement occurred in 56% of IBS and 60% of FC patients following dietary restriction. The number of symptoms decreased significantly in both groups (P<0.01) and correlated with the improvement index (IBS P<0.05, FC P<0.025).

Conclusions: Combined sugar malabsorption patterns are common in functional bowel disorders and may contribute to symptomatology in most patients. Dietary restriction of the offending sugar(s) should be implemented before the institution of drug therapy.

Background: About one-third of patients with severe ulcerative colitis do not respond to conventional therapy and require urgent colectomy. It was recently shown that cyclosporin is effective in some of these patients.

Objectives: To review the current experience of six hospitals in central Israel that used cyc-losporin in patients with severe ulcerative colitis.

Methods: The files of all 32 patients treated with cyclosporin for corticosteroid-resistant ulcerative colitis were reviewed. Activity of disease was measured by a clinical activity, index colonoscopy and laboratory tests.

Results: The average duration of treatment with intravenous cyclosporin was 12.7 days (range 9–28) after which the disease activity index dropped from an average of 14.22 to 4.74. The mean time for response was 7.5 days (4–14). Twelve patients (40%) required surgery within 6 months and another 6 patients (18.8%) were operated on after more than 6 months. Twelve patients (37%) maintained remission for at least 6 months and did not require surgery. In one patient treatment was stopped because of non-compliance and one was lost to follow-up. There were numerous side effects, but in only one case with neurotoxicity was treatment withdrawn.

Conclusions: Cyclosporin is a relatively safe and effective treatment for severe ulcerative colitis. It induced long-term remission in 37% of the patients, and in those who required surgery the treatment resulted in an improved clinical condition before the operation.

Background: Ulcerative colitis begins in early childhood in 4% of cases. Medical therapy is non-specific, and as many as 70% of children will ultimately require surgery. The dynamic growth, physical and psychological changes that characterize childhood are severely compromised by the complications of ulcerative colitis and its therapy.

Objective: To review the outcome of children undergoing early surgery for ulcerative colitis at a tertiary medical center in Israel.

Methods: A retrospective review was conducted of all children operated on following failure of medical therapy for ulcerative colitis during a 5 year period.

Results: Eleven children underwent a J-pouch procedure with ileo-anal anastomosis in one to three stages. Postoperative complications included recurrent pouchitis in 5 patients, intestinal obstruction in 3, fistula with incontinence in one, stricture in one, and wound infection in 4. Follow-up revealed that most of the patients have three to four soft bowel movements daily. All currently enjoy normal physical activities and a rich social life.

Conclusions: The quality of life in children with ulcerative colitis was markedly improved following J-pouch surgery. This procedure was not associated with major complications. We recommend early surgery as an alternative to aggressive medical therapy in children with this disease.

Background: General pediatricians in Israel are actively involved in the initial evaluation, resuscitation and management of traumatized children. However, pediatric trauma care is not a part of pediatric specialty training in Israel, and the few Advanced Trauma Life Support^R courses per year are insufficient for most pediatricians working in accident and emergency care.

Objective: To examine the value of the course in relation to the limited resources available for such training.

Methods: A telephone survey of 115 pediatricians who had taken the course between 1990 and 1994 was conducted. The responding physicians (67%) were asked to complete a specially designed questionnaire on life-saving procedures that were taught in the course. In addition, they were asked to subjectively assess the practical utility of the course.

Results: Forty-three (56%) pediatricians reported that they routinely treated both adult and pediatric trauma cases. Of these, 81% performed 27 life-saving ATLS^R procedures. Pediatric trauma was treated by only 22 (28%), of whom 72.3% performed 18 life-saving ATLS^R procedures. These pediatricians ranked the courses as being "very high" to "high" in impact.

Conclusions: These figures indicate that an ATLS^R course designed specifically for pediatricians can markedly improve pediatric trauma care. To ensure standard education and patient care, such a course should be developed and made a mandatory component of residency training. Further studies to examine the objective impact of the courses on pediatric trauma care should be carried out.

Background: Urinary tract infection is one of the most common bacterial infections. Since antibiotics are given empirically, it is necessary to assess the distribution and susceptibility of the microorganisms in each case.

Objectives: To evaluate the demographic characteristics of ambulatory patients with UTI, the distribution and susceptibility of uropathogens, and the risk factors associated with trimethoprim-sulfamethoxazole resistant bacteria in women.

Methods: During 12 days in August 1997 all the urine cultures sent to the Tel-Hanan Laboratory (Haifa) were evaluated. Demographic characteristics of the patients, their underlying diseases and the previous use of antibiotics were obtained.

Results: During the 12 day survey 6,495 cultures were sent for evaluation. Of the 1,075 (17%) that were positive 950 were included in the study; 83.7% were from females, of whom 57% were ≥50 years old. Escherichia coli was the most common pathogen, with 74.7% in the female and 55% in the male population; 86.2% of the E. coli were resistant to amoxicillin, 38.8% to cephalexin and 46.8% to TMP-SMX. Cefuroxime (4.2%), ofloxacin (4.8%), ciprofloxacin (4.8%) and nitrofurantoin (0.4%) showed the lowest rates of resistance. By a multivariant analysis, post-menopause and recurrent UTI were found to be independent factors related to TMP-SMX resistance in women.

Conclusion: In northern Israel, ampicillin, cephalexin and TMP-SMX cannot be used empirically in the treatment of community-acquired UTI. Post-menopause and recurrent UTI are independent factors associated with TMP-SMX resistant pathogens in women.
