Decrease in asthma mortality rate in Israel from 1991-1995: is it related to increased use of inhaled corticosteroids?

BACKGROUND: Asthma mortality rates (AMRs) during the last several decades increased in many countries with developed medical services, including Israel. The reasons for this trend were never established. Recent data suggested that this trend is changing. OBJECTIVES: We sought to compare the AMR in Israel during 1991-1995 with that of the previous decade and to investigate a possible correlation between mortality rates and use of inhaled corticosteroids (ICSs) and beta(2)-agonists. METHODS: Statistical data on the AMR in Israel during 1981-1995 were extracted. Data were analyzed for 5- and 10-year periods (1981-1990) and compared with a 5-year period (1991-1995). Data on ICS and beta(2)-agonist sales were extracted from the marketing companies' official reports. RESULTS: The mean AMR per 100,000 population per year during 1981-1990 in the 5- to 34-year-old group was 0.393 +/- 0.055 and decreased to 0.202 +/- 0. 046 during the 1991-1995 period (P =.03). There was no significant difference between changes in mean AMR in the 35- to 64-year-old or in the 5- to 64-year-old group during the same periods (4.568 vs 4. 063 and 2.480 vs 2.133). The mean ICS unit sales rates (per 100,000 population per year) between 1982-1990 and 1991-1995 were 21.70 and 190.45, respectively (P <.05). The correlation between ICS sales and AMR was -0.631 (P =.016). Sales of beta(2)-agonists did not change significantly during the study period. CONCLUSIONS: We identified a trend of decreased AMRs in Israel during 1991-1995. The decline in AMRs paralleled the increase in ICS sales, whereas the sales of inhaled beta(2)-agonists did not change significantly. One may speculate that the decrease in AMR may be the result of better anti-inflammatory treatment, as reflected by the increased use of ICSs. The feasibility of reducing AMRs in a country such as Israel, with low AMRs to start with, by improving medical treatment is encouraging.

Hospitalizations due to falls in Jewish and Arab children in northern Israel.

In Israel, there are no epidemiological data regarding nonfatal childhood falls. A retrospective survey was conducted in order to find epidemiological characteristics of childhood falls among the different populations of northern Israel. During the years 1993 through 1995, 3082 children were hospitalized in Rambam Medical Center (RMC) due to injury. The children were subdivided into the four main populations: Jewish and Arab residents of Haifa region (the main metropolitan area) and Jewish and Arab residents of the Galilee region (the rural region). All of the children who suffered injury that required mechanical ventilation and careful assessment were admitted to the PICU. The charts of the children admitted to the PICU were then further studied. The demographic characteristics of all the cases of falls were statistically analyzed and the annual admission rates due to falls were calculated using the national statistical registrations of children in Israel. Falls were responsible for 1049 admissions due to injury, one third of the total number of children who were admitted due to an injury. Most of the children were five years of age or younger. Two thirds of the total childhood falls were of Arabs. The majority of the admissions were of two major sub-populations of northern Israel: Arab residents of Galilee region (66%) and Jewish residents of Haifa region (34%). Higher admission rate was found among Arab children of the Western Galilee district in comparison with Jewish children of the Haifa district. Most of the children who were admitted to the PICU were Arabs: nearly all of these children were from the rural region. More Arab than Jewish children who fell were admitted to the PICU and the majority of these cases were falls from buildings (private houses). Arab children of the rural region were responsible for 95% of the cases. These falls were mainly in staircases (46%) and from balconies (21%), roofs (11%) and windows (11%). The findings of the present study suggest that young Arab rural children in northern Israel are at high risk to a severe injury due to fall. Possible causes are discussed and a preventative intervention is suggested.

Complementary medicine in Israel.

In recent years, the status of complementary medicine in Israel has appeared frequently on the public agenda. The debates and the newspaper headlines concerned with this subject usually deal with legal aspects of the subject, including the relation between complementary medicine and the medical establishment. With the enactment in 1995 of the Compulsory Health Insurance Law, debate over the issue intensified, with the public divided over any proposal to make complementary medicine part of the services guaranteed by law. This paper addresses the current status of complementary medicine in Israel, describes the introduction of complementary medicine to Israel, attitudes toward it of both consumers and medical professionals, and the question of its legal status. While no comprehensive survey describing all aspects of this subject in Israel has yet been undertaken, this paper is based on a survey of the professional literature in Israel, especially that of the Israeli scientific-medical community, a survey of the general press, and an analysis of the health insurance law and its position with respect to the complementary medicine.

Four decades of shigellosis in Israel: epidemiology of a growing public health problem.

Despite the improved standard of living in Israel, shigellosis remains a common disease. Examination of trends in the incidence of shigellosis in Israel between 1951 and 1987 showed a period of declining rates followed by an increase in the reported incidence beginning around 1969. This increase was mainly due to Shigella sonnei; rates of infection with Shigella flexneri remained relatively constant. Trends showed marked differences between age groups and between ethnic groups. In comparison, the rates in the United States--much lower than those in Israel--began to decline in the early 1950s and have remained low. The incidence in Israel is now about 20 times higher than that in the United States. Thus shigellosis remains a major and growing public health problem in Israel, a country that has enjoyed a dramatic improvement in basic sanitary services and infrastructure over the past few decades. This disturbing finding lends urgency to efforts to control the disease.

Radiocesium body burdens in immigrants to Israel from areas of the Ukraine, Belarus and Russia near Chernobyl.

Of the 500,000 immigrants from the former Soviet Union who came to Israel during 1990-1993, about 100,000 are estimated to have come from radiocontaminated areas near Chernobyl. These people were subject to chronic uptake of environmental radiocesium over protracted periods. During October-November 1991, a joint Israeli-Canadian investigation measured radiocesium body burdens in immigrants to Israel from the Ukraine, Belarus, and the southern Russian republic in order to provide factual information on radiocesium levels to concerned immigrants and to relate the body burdens to the geographic area of residence before coming to Israel. Assessments were made of 137Cs body burdens in 1,228 volunteer men, women, and children. These measurements were accompanied by medical assessments based on clinical histories and examinations. Radiocesium levels were strongly dependent on the duration of residence in Israel, with the highest levels being found in the most recent immigrants. The maximum level, extrapolated back to the time of leaving the former Soviet Union, was estimated to be about 0.83 kBq (10.3 Bq kg-1). Of the most recent immigrants from the Kiev region (< 101 days in Israel), only 15% had back extrapolated body burdens > 50 Bq, whereas 53% of those coming from Gomel and other towns in the contaminated zones (> 3.7 x 10(10) Bq km-2 of radiocesium) had detectable levels > 50 Bq. People coming from the latter region had significantly higher body burdens as compared to those from the former, in accordance with the higher degree of ground radiocesium contamination reported for the latter region. Women and children showed considerably lower total radiocesium content in comparison to men. All radiocesium body burdens at the time of measurement were too low to be of health concern.

Epidemiology of Crohn's disease in Israel: a survey of Israeli kibbutz settlements.

OBJECTIVE: The prevalence of Crohn's disease ranges from 10 to 70 cases per 100,000 population, and is 3-8 times more common among Jews. However, this excess risk is not evident in the Jewish population of Israel. Recently we have described a significant increase in the prevalence and incidence of Crohn's disease in the south of Israel. The aim of this study was to confirm this trend in a stable population found in communal (kibbutz) settlements. METHODS: We repeated a community-based survey in 124,400 kibbutz residents, 10 yr after our first study. This population represents 5% of the Jewish population of Israel. All Crohn's disease patients were located by contacting the kibbutz clinics of the 269 kibbutz settlements (100% compliance). Data was updated to December 31st, 1997, which was designated the point prevalence date, and included information on gender, age, origin, education, profession, extent of the inflammatory process, clinical spectrum of the disease, therapy, complications of the disease, and treatment. The average annual incidence for the 10 yr was calculated from the prevalence data. Only cases with a definite diagnosis of Crohn's disease made in a recognized gastroenterology unit were accepted into the study. RESULTS: There were 81 confirmed cases of Crohn's disease and the prevalence rate rose from 25.5/100,000 in 1987 to 65.1/100,000 in 1997 (p < 0.001). The mean annual incidence rate for this period (1987-1997) is 5.0/100,000/yr. Prevalence rates were higher in women than men, and in those born in Israel or Europe/America than in Asia/Africa. The mean age at presentation of the disease was lower in 1997 than in 1987, 37.4 +/- 17.0 and 45.0 +/- 17.0 yr, respectively (p = 0.041). Prevalence was highest in men with > 16 yr of education, and in women with 11-12 yr education, 119.7 and 100.3/100,000, respectively. CONCLUSIONS: During the decade 1987-1997, the prevalence of Crohn's disease has increased in Israel and is approaching the rates in Europe and America.

The fall and rise of gonorrhoea incidence in Israel: an international phenomenon?

BACKGROUND: There is evidence of a recent resurgence of the incidence of gonorrhoea in some countries. AIM: To examine trends in gonorrhoea incidence in Israel and compare them with the United States and countries in Europe METHOD: The 1967-2001 annual incidence of gonorrhoea in Israel was obtained from the Israel Ministry of Health's department of epidemiology and for the United States from summary reports of the Centers for Disease Control. The incidence of gonorrhoea in European countries was extracted from the World Health Organization, Health for All database. RESULTS: In Israel, following a long period of decline from 40 per 100 000 in 1970 to 0.74 per 100 000 in 1997, incidence rates began to increase in 1998 to 13.8 per 100 000 in 2001. This pattern parallels those observed in a number of European countries and to some extent, in the United States. Most reported morbidity in Israel occurs among males aged 20-44 years. CONCLUSIONS: The resurgence of gonorrhoea does not appear to be explained solely by behavioural changes. Transmission of the disease should be further studied among different subpopulations in order to develop new prevention strategies.

Population group differences in trends in stroke mortality in Israel.

BACKGROUND AND PURPOSE: In Israel, stroke is the third most common cause of death. In 1997 stroke accounted for 2905 deaths (8.1% of total), 1390 of them among men (7.5% of total; crude mortality rate of 48.3/100 000) and 1515 among women (8.6% of total; crude rate of 51.7/100 000). This report presents trends on stroke mortality by population group and estimates of morbidity in Israel. METHODS: Data on stroke mortality in Israel during 1969-1997 were obtained from the Israel Central Bureau of Statistics. Age-specific and age-adjusted mortality rates were calculated for the 2 main population groups. Data on morbidity were obtained form the 1996/1997 National Health Survey. Hospitalization rates due to stroke are based on the national hospitalization data. RESULTS: A monotonic decrease in stroke mortality is evident in Jews during 1969-1997 in both sexes. Age-adjusted mortality rates declined by 62.5% for Jewish men and by 73.4% for Jewish women during 1969-1997. Among Arabs, there was a general decreasing trend in the mortality for both sexes during 1973-1997. The main difference in population group mortality trends was found in the group aged >/=75 years: a statistically significant decrease in mortality rates for Jews is evident, while no decrease is apparent for Arabs. On the basis of available data for 1990, an estimated 13 000 patients with stroke were hospitalized during 1997. CONCLUSIONS: During the last 25 years, age-adjusted stroke mortality in Israel has declined substantially, but the decline has been much greater among Jews than Arabs. The group aged >/=75 years shows the greatest difference in trends between Jews and Arabs. This finding may be explained by differences in risk factor distribution and case fatality rates.

Parental communication and psychological distress in children of Holocaust survivors: a comparison between the U.S. and Israel.

To determine how the children of Holocaust survivors in Israel and the U.S. differ on measures of parental communication and psychological distress, we performed a comparative study on 140 subjects in the U.S. and 54 in Israel using a written questionnaire. Respondents in Israel reported more communication by their parents, but also a higher level of demoralization; this may be due to more demoralization among the general population. In both populations, parents' general communication correlated negatively with anxiety, depression and demoralization and positively with guilt. Parents' Holocaust communication resulted in similar findings; however, in Israel only a negative correlation with demoralization reached significance. Parental communication about the Holocaust thus seems to be of less importance in Israel in determining the children's psychological outcome. This may be due to a greater role by Israeli society in forming children's perception of the Holocaust.

Primary pulmonary hypertension in Israel: a national survey.

OBJECTIVES: To characterize the incidence of patients with primary pulmonary hypertension (PPH) in Israel and their outcomes. METHODS: We have evaluated retrospectively all the patients in Israel in whom PPH was diagnosed between the years 1988 and 1997. We looked at medical history, hemodynamic data, pulmonary function and gas exchange, and demographic variables. Patients were followed up for survival until November 1997. Life table analysis and Kaplan-Meier statistics were used to estimate the overall survival distribution. Regression analysis was used to examine the relations between survival and selected variables. RESULTS: Overall, we found 44 patients with PPH. The estimated incidence of PPH in Israel is 1.4 new cases per year per million population. The mean (+/- SD) age at diagnosis was 43 +/- 13 years. In the Jewish population, PPH was more frequent among immigrants from Europe and the United States. The mean interval from the onset of symptoms to diagnosis was 3 years (median, 2 years). The median survival time was 4 years. The 1-year, 3-year, and 5-year survival rates were 82%, 57%, and 43%, respectively. The major variables influencing the survival rate were the following: interval from symptom onset to diagnosis; and hemodynamic measurements (ie, mean pulmonary artery pressure, mean right atrial pressure, and cardiac index). In comparison to rates discerned from the National Institutes of Health registry data, the survival rate in Israel is somewhat better and prognosis is influenced by similar hemodynamic variables. CONCLUSION: PPH is a rare and fatal disease in Israel. New therapeutic modalities such as prostacyclin therapy and lung transplantation may improve survival among patients with this malignant disease.

Absence of Kaposi sarcoma among Ethiopian immigrants to Israel despite high seroprevalence of human herpesvirus 8.

OBJECTIVE: To determine the prevalence of Kaposi sarcoma (KS) and human herpesvirus 8 (HHV-8) seropositivity in Ethiopian Jewish immigrants to Israel. METHODS: A Western blot assay was used to determine the seroprevalence of HHV-8 in serum samples from 202 randomly selected human immunodeficiency virus (HIV)-negative and 47 HIV-positive Ethiopian immigrants; samples were obtained on arrival of the immigrants in Israel. The Israel Cancer Registry provided comprehensive data on the occurrence of KS among Ethiopian immigrants and in the non-Ethiopian population of Israel. RESULTS: A total of 39.1% and 57% of the HIV-negative and HIV-positive Ethiopians, respectively, were infected with HHV-8 (P<.03). However, none of the Ethiopians examined and none of the other HIV-negative Ethiopians among about 45,000 immigrants had KS. Moreover, only 1 (0.85%) of 118 Ethiopian patients with acquired immunodeficiency syndrome (AIDS) developed KS compared with 49 (12.5%) of 391 non-Ethiopian AIDS patients (P<.001). CONCLUSION: Although HHV-8 infection is common in Ethiopian Jewish immigrants to Israel, these patients almost never develop KS, in marked contrast to the strong association usually observed. The mechanism behind this population's unique protection requires further study.

[Israel hospital pharmaceutical services: a national survey].

Results of a 1996 survey of hospital pharmaceutical services in Israel are presented. A questionnaire was mailed to 46 pharmacy directors in Israel hospitals of which a total of 33 were returned (72%). The main services provided at hospital pharmacies are production of pharmaceuticals and inventory management. The pharmacy directors estimated that more then half of their pharmacists' time was spent on technical work that did not need their academic, professional knowledge. In Israel general hospitals there are on the average 1.23 full time pharmacist positions per 100 hospital beds and 1.09 positions for other pharmacy employees. A similar survey carried out in the United States showed an average of 7.4 pharmacists per 100 hospital beds. Pharmacists there have broad clinical roles which, in general Israeli pharmacists do not have. Computer systems are used in our pharmacies mainly for inventory management. About half of the directors did not think that the location, structure and furnishings of their pharmacy were appropriate for its role. Under current conditions, Israel hospital pharmacies are not organized to provide pharmaceutical services beyond inventory management and pharmaceutical production. Appropriate budgets and personnel are required to develop clinical pharmacy services at Israel hospitals. This would lead to improved quality of drug treatment and cost-containment and would allow pharmacists to exploit their knowledge, skills and training that under the current system, are only partially utilized.

Changes in drug economy in Israel's health maintenance organizations in the wake of the National Health Insurance Law.

BACKGROUND: It is not clear to what extent the drug economy in Israel's health maintenance organizations is responsive to major healthcare reforms. OBJECTIVE: To provide information on how drug expenditures, revenues, net costs and drug utilization have changed in the wake of the 1995 National Health Insurance Law in Israel. METHODS: This study compares trends in aggregate sick fund expenditures, revenues (patient co-payment) and net costs (expenditures less revenues) in Israel's four health maintenance organizations for the 3 year period 1992-1994 prior to the introduction in 1995 of the NHI Law, with that of the 4 year period 1995-1998 following its introduction. This analysis is similarly carried out for Israel's largest HMO, Clalit Health Services, and for the three smaller HMOs combined. RESULTS: The pace of growth in the pre-NHI era in drug expenditures and particularly in drug revenues was drastically reduced in the NHI era--whether measured as totals or as per insured person (age-adjusted) or in real terms at constant medicine prices. These trends were mirrored to a large extent in Clalit and in the other HMOs, with some important differences noted between the HMOs. Despite declining growth rates in drug expenditures and net costs, the proportion of these measures of the total HMO economy actually increased in the NHI era, reversing the trend seen in the pre-NHI era. CONCLUSIONS: The impact of the NHI Law on the HMO drug economy has been substantial. The evidence suggests a decline in both the qualitative (basket of drugs consumed) and quantitative (volume of drugs consumed) elements of growth. These changes in expenditure and revenue trends are discussed in the light of the evolving involvement of the Israel Ministry of Health in drug policy within the framework of the NHI, with emphasis on the basket of drugs reimbursed and co-payments for prescriptions.

Self-reported health status of immigrants from the former Soviet Union in Israel.

BACKGROUND: A mass influx of immigrants from the former Soviet Union to western countries and Israel followed the demise of the Soviet Bloc at the beginning of the 1990s. It was expected that these immigrants would have a higher morbidity and mortality rate similar to that in the former USSR. OBJECTIVES: To measure and compare self-reported diseases, subjective health and health services utilization of a representative sample of veteran Israeli Jews and immigrants from the former USSR. METHODS: A cross-sectional survey of Israeli adults was performed by telephone interviews. The survey included 793 Israeli Jews, of whom 124 were immigrants from the former USSR who arrived in Israel after 1989 (response rate 52%). RESULTS: The immigrants reported a higher rate of diseases and sub-optimal health after adjustment for other variables. However, no excess in health services utilization was reported. A time trend of reporting sub-optimal subjective health was observed: the longer the immigrants spent in Israel the more their reporting patterns resembled those of immigrants who arrived in Israel before 1970. Those who arrived after 1994 more frequently reported having a chronic disease. CONCLUSIONS: Acculturation seems to have been the main effect on the immigrants' health, together with a healthy migrant effect at the beginning of the 1990s. The immigrants' health was worse in the later years of the immigration wave, partially reflecting the poor state of health in the former Soviet Union compared to Israel.

Health knowledge, attitudes, and practice (KAP)--a basis for health promotion policy in Israel.

OBJECTIVE: To review how health promotion policy can be based on research data. DATA SOURCES: The Department of Health Promotion, Ministry of Health, Israel, in collaboration with Midgam Research and Consultation Company and the Israel Center for Disease Control have conducted ongoing research on health knowledge, attitudes, and practice in Israel as a basis for health policy. MAIN FINDINGS: Based on data from 1995 to 2000: 1. There is a positive trend in healthy dietary habits. 2. There is no decrease in smoking rates. 3. There is an increase in drinking rates of wine. 4. There is an increase in aerobic exercise. More Israelis declare they eat healthy foods, but currently this is only for 50% of the population. There is a need for health promotion efforts to further increase positive dietary habits. There is an immediate need for extensive health promotion efforts to decrease smoking rates in Israel. Also, there is a need for health promotion campaigns to decrease drinking in Israel. Although more people are participating in aerobic physical exercise, there is a need to further increase this number. CONCLUSION: Data on health knowledge, attitudes, and practice is an important source for health promotion policy. By trends seen in a national survey of health knowledge, attitudes, and practice conducted every two years, additional health promotion policy can be shaped.

Estimates of demand for abortion among Soviet immigrants in Israel.

In 1990, more than 185,000 Soviet Jews emigrated to Israel, increasing Israel's population by 4 percent; 148,000 more arrived in 1991. Given the fertility and abortion patterns prevailing among Soviet women in their native country, this article inquires about the short-range expected increase in abortion demand in Israel engendered by this large migratory inflow. Estimation techniques based on the abortion experience of an earlier wave of Soviet-born immigrants in Israel reveal that the increase in requests for abortion brought about by the 1990 immigrants may reach up to 14 percent, and as high as 24 percent for the combined immigration waves of 1990 and 1991. The expanded demand for abortions in Israel engendered by the new Soviet immigrants necessitates an expansion of both family planning services and of the medical committees entitled to grant a legal abortion. A failure in these fields would benefit illegal abortion.

[Asthma management in adult emergency departments in Israel in comparison to asthma guidelines].

BACKGROUND: Asthma management is in focus all over the world. It is constantly updated, including aspects of Emergency Department (ED) care, on the basis of global and national evidence-based clinical guidelines. Despite the existence of these guidelines, the management of asthma, including management in the ED, is lagging behind. AIM: This study strives to evaluate various aspects of asthma management in the EDs in Israel. METHOD: A questionnaire was sent to each Head or Deputy Head of all the adult EDs in Israel. The questionnaires were collected within 16 days in December 2000. Ninety-six percent of all adult EDs in Israel responded. The mean response of each ED to all the questions was 99.5%. RESULTS: Oximetry on admission is performed for every patient in a third of the EDs although an oximeter is available in every ED. Measurements of airway obstruction severity by PEFRm or FEV1 in more than 50% of patients before hospital admission or discharge is only conducted in 9% of the EDs and in 52% of them it is not measured at all. Inhalation of a short beta-agonist combined with anticholinergic is performed in 84% of EDs. Corticosteroids are given to more than 80% of the arriving patients in only 54% of EDs and on discharge it is continued in all or almost all patients in 63% of EDs. A written time interval for the next medical visit after discharge from ED is not specified in 50% of EDs. In contrast to these findings, there is almost complete accordance among EDs (88%) that asthma management in the ED should follow formal guidelines and that common guidelines for asthma management should be adopted by all EDs in Israel (71%). CONCLUSIONS: The discrepancies between the existing clinical guidelines for asthma management in the ED and its actual use on the one hand, and the agreement among EDs on the importance of the guidelines on the other hand, are raising the necessity for common guidelines for asthma management in the EDs in Israel. Perhaps, more importantly, it highlights the urgent need for new effective and creative ways to implement asthma guidelines into routine ED practice.

Healthy aging around the world: Israel too?

Mortality rates have been falling at all ages, even for very old cohorts, in most western countries as well as in Israel. The question remains open as to whether morbidity rates are also decreasing, especially for Israel's elderly. While health is improving in almost all industrialized countries, the situation in Israel is not yet resolved. While the more recent cohorts of the young-old (65-74 years) are healthier than their predecessors, Israel's old-old (75+) may still be lagging behind other countries with regard to improvements in health status. This phenomenon is not well understood but could be explained in part by the more severe formative experiences of many of Israel's very elderly cohort.
