RESUMEN

Physician maldistribution affects remote and rural population health indicators and as such constitutes a major concern for health systems. Various countries, including Israel, have sought to remedy this problem, often by implementing more than one intervention simultaneously. In this paper, we explored the considerations that motivated Israeli residents to opt for a position in the periphery, as well as potential factors that could facilitate their retention in these underserved areas. We found that the motivation driving young physicians to specialize in a specific hospital includes personal- and family-oriented considerations (proximity to the nuclear family, perceived quality of life and lifestyle) as well as professional considerations (prior acquaintance with a hospital and a specific hospital department, department characteristics, availability of a residence position in a preferred specialty, prospective professional advancement). We therefore argue that the key to recruitment and retention of young physicians in remote areas lies in tailored interventions that take personal, professional and regional issues into account, preferably in consultation with the physicians themselves. The prominence of personal issues in the interviews with young physicians suggests that effective interventions should support a work-life balance. Hence success in attracting residents as a first step towards correcting physician maldistribution hinges upon coordinating policies in the medical field with policies in non-medical arenas - education, welfare, local authorities.

RESUMEN

BACKGROUND: In 2005, Clalit Health Services (CHS), the largest health maintenance organization in Israel, initiated an intervention program aimed at reducing the prevalence rate of infantile anemia (IA). This study evaluated the progress made during the intervention (2005-2014) and its yield 5 years after it ended (2019). METHODS: The CHS database was retrospectively reviewed twice yearly from 2005 to 2014 for repetitive samples of children aged 9 to 18 months regarding the previous half-year interval, and a single sample in 2019. Data were collected on gender, ethnicity (Jewish/non-Jewish), socioeconomic class (SEC; low/intermediate/high), hemoglobin testing (yes/no), and hemoglobin level (if tested). Excluded were infants with documented or suspected hemoglobinopathy. RESULTS: At study initiation, the rate of performance of hemoglobin testing was 54.7%, and the IA prevalence rate was 7.8%. The performance rate was lower in the Jewish than the non-Jewish subpopulation. The low-SEC subpopulation had a similar hemoglobin testing rate to the high-SEC subpopulation but double the IA prevalence rate. Overall, by the end of the intervention (2014), the performance rate increased to 87.5%, and the AI prevalence rate decreased to 3.4%. In 2019, there was little change in the performance rate from the end of the intervention (88%) and the IA prevalence was further reduced to 2.7%. The non-Jewish and low-SEC subpopulations showed the most improvement which was maintained and even bettered 5 years after the intervention ended. CONCLUSIONS: The 10-year IA intervention program introduced by CHS in 2005 led to a reduction in IA prevalence rate to about 3.5% in all sub-populations evaluated. By program end, the results in the weaker subpopulations, which had the highest prevalence of IA at baseline, were not inferior to those in the stronger subpopulations. We recommended to the Israel Ministry of Health to adopt the intervention countrywide, and we challenge other countries to consider similar interventions.

RESUMEN

OBJECTIVES: This study assessed rates of ambulatory care-sensitive condition (ACSC) admissions within a healthcare system to identify areas for intervention. STUDY DESIGN: This was a multiyear cross-sectional study using the data warehouse of Clalit Health Services (Clalit), the largest payer/provider healthcare system in Israel, with complete clinical records for more than 4 million members. All admissions from 2009 to 2014 were included in the study. Discharge diagnoses were identified using International Classification of Diseases, Ninth Revision codes. METHODS: We provide adjusted rates (per 100,000 Clalit population adjusted by age and sex to the 2005 Organisation for Economic Co-operation and Development population) for all admissions, by discharge diagnoses, for each year. We identify the highest adjusted rates (relative and absolute) by both catchment area and hospital affiliation (Clalit or non-Clalit). RESULTS: ACSC-related admissions made up 16.2% of all admissions for the 5 years studied, and the overall rate increased by 26.8% from 2009 to 2014. The conditions with the highest admission rates in all years and all catchment areas were pneumonia and congestive heart failure. There was extreme variation among catchment areas for hypertension-related admissions. Within the Clalit hospitals, ACSCs accounted for 20.5% of admissions; within non-Clalit hospitals, ACSCs accounted for 13.6% of admissions. CONCLUSIONS: In evaluating the rates of ACSC-related admissions, this study demonstrates the contribution of a single, longitudinal benchmark. This study also suggests that hypertension, congestive heart failure, and pneumonia may be areas for future intervention in Clalit.

RESUMEN

OBJECTIVES: To compare the prevalence of cardiovascular diseases and risk factors in Holocaust survivors with that of Jewish immigrants from Europe and America. DESIGN: Population-based, cross-sectional study. SETTING: Clalit, a large Israeli healthcare provider. PARTICIPANTS: Holocaust survivors (n=83,971) and a comparison group of Jewish individuals born in North or South America or European countries not under Nazi occupation or who immigrated to Israel before 1939 (n=16,058) (mean age 84±7, 61% female) MEASUREMENTS: Univariate and multivariable logistic regression analyses of cardiovascular diseases and risk factors. Matching the comparison group to Holocaust Survivors on propensity scores for exposure. RESULTS: The prevalence of ischemic heart disease (38.7% vs 31.3%), congestive heart failure (10.9% vs 9.1%), past stroke (15.7% vs 13.4%), and peripheral vascular disease (9.5% vs 7.9%) was higher in Holocaust survivors (p<.001 for all comparisons). Similar results were found for cardiovascular risk factors (diabetes mellitus (14.4% vs 13.6%), hypertension (89.3% vs 86.4%), dyslipidemia (75.9% vs 74.0%) (p<.001 for all comparisons). In multivariable analysis, matched on propensity scores and controlled for confounders, odds ratios for men and women were higher for diabetes (1.23, 1.55), dyslipidemia (1.53, 1.51), hypertension (1.56 , 1.94), stroke (1.18, 1.17), and ischemic heart disease (1.18, 1,40), but not congestive heart failure (0.95, 1.02). A Positive association was noted for peripheral vascular disease in males (1.20) but not females (0.96). CONCLUSION: Prevalence of cardiovascular diseases and risk factors was higher in Holocaust survivors. These associations were stronger in women in most cases.

RESUMEN

BACKGROUND: The purpose of this study was to examine the incidence of malignant diseases among Holocaust survivors in Israel compared with European and American immigrants who did not experience the Holocaust. METHODS: Study subjects included Holocaust survivors born in European countries under Nazi occupation before 1945, who immigrated to Israel after 1945 and were alive as of the year 2000. Living survivors were identified based on recognition criteria in accordance with the Holocaust Survivor Benefits Law. The comparison group consisted of Clalit enrollees who were born before 1945 in European countries not under Nazi occupation and were alive in 2000 or were born in any European country or America, immigrated to Israel before 1939 and were alive in 2000. The incidence of malignant diseases was compared in univariate and Poisson regression models analyses, controlling for age, smoking, obesity, diabetes and place of residence. RESULTS: The study included 294,543 Holocaust survivors, and the mean age at the beginning of follow-up was 74 ± 8.7 years; 43% males. In multivariable analyses, the rate ratio (RR) values for males and females were 1.9 and 1.3 for colon cancer, 1.9 and 1.4 for lung cancer, 1.6 and 1.4 for bladder cancer and 1.2 and 1.3 for melanoma, respectively. For prostate cancer in males, the RR was 1.4, while for breast cancer in females, it was 1.2. CONCLUSIONS: The incidence of malignant diseases among Holocaust survivors residing in Israel was higher than that among non-Holocaust survivors. These associations remained statistically significant in a multivariable analysis and were stronger for males.

RESUMEN

OBJECTIVES: To assess the effect of hip fracture on healthcare utilization among elderly patients. DESIGN: Retrospective cohort study. SETTING: Eight general hospitals in Israel, owned by Clalit. PARTICIPANTS: Enrollees >65 years, admitted with a hip fracture during 2009-2013. MAIN OUTCOME MEASURES: Data collected included demographics, comorbidities, admission details related to the surgical and rehabilitation hospitalizations, mortality and costs. Mean monthly costs before and after the event were compared. Quantile regression was used to analyze associations between patient characteristics and healthcare expenditure in univariate and multivariate analysis. RESULTS: Of 9650 patients admitted with hip fracture during the study period, 6880 (71%) were Clalit enrollees and included in the present study (69% females, median age: 83 years). Total mean monthly costs increased by 96% during the follow-up year ($1470 vs. $749). Costs for rehabilitation accounted for 40% of costs during the first follow-up year. Mean monthly non-rehabilitation costs increased by 21% ($877 vs. $722). Several factors were found to be consistently associated with increased mean monthly costs during the follow-up year. These included Charlson's comorbidity index, hypertension, baseline expenditure in the base year, the location of the fracture, procedure performed, department on admission, admission to the intensive care unit, discharge to a rehabilitation facility and mortality during the follow-up year. CONCLUSIONS: Hip fractures in adults in Israel are associated with a significant increase in healthcare utilization and costs. The largest increment was seen in costs for rehabilitation. However, increased costs were noted in all sub-categories of healthcare costs.

RESUMEN

The association between hepatitis B and autoimmune disorders has been intriguing for decades. Many reports have speculated on the possible linkage between these two conditions, yet never before data driven from a large national database was utilized in order to investigate this issue. The objective of this study was to investigate the association between SLE and hepatitis B carrier state. Patients with SLE were compared with age- and sex-matched controls regarding the proportion of hepatitis B carrier state in a case-control study. Chi-square and t tests were used for univariate analysis, and a logistic regression model was used for multivariate analysis. The study was performed utilizing the medical database of Clalit Health Services. The study included 5018 lupus patients over the age of 20 years and 25,090 age- and sex-frequency-matched controls without SLE. The proportion of hepatitis B carriers was higher in SLE patients as compared to controls (0.9 and 0.56 %, respectively; p < 0.001). A significant association was also observed among patients in lower socioeconomic status. In a multivariate logistic regression analysis, SLE was significantly associated with hepatitis B (OR = 1.828, 95 % CI = 1.291-2.590). Patients with SLE have a greater proportion of hepatitis B carrier state than matched controls.

RESUMEN

There is substantial evidence that aortic aneurysm (AA) may be a manifestation of several systemic rheumatic disorders. However, only several studies have assessed the association between rheumatoid arthritis (RA) and AA. The aim of this study was to evaluate the incidence of AA in RA patients in a case-control study. A retrospective case-control study was performed utilizing the database of Clalit Health Services (CHS), a large healthcare provider organization in Israel. Data available from the CHS database included age, sex, socioeconomic status (SES), and diagnoses of chronic diseases, including AA. Patients over the age of 20 years who were diagnosed with RA ("cases") were compared with a sample of age- and gender-matched enrollees without RA ("controls") regarding the prevalence of AA. Chi-square and t tests were used for univariate analysis, and a logistic regression model was used for multivariate analysis. The study included 11,782 RA patients and 57,973 age- and gender-matched controls. The proportion of AA was significantly higher in RA patients (0.72 %) compared to the control group 0.49 % (odds ratio (OR) 1.48, 95 %; confidence interval (CI) 1.15-1.88; p = 0.002). A multivariate analysis that evaluated covariates associated with AA revealed an independent association of AA and RA after adjustment for different factors including age, gender, SES, and smoking status (OR 1.406, 95 %; CI 1.094-1.789; p = 0.006). Our study has demonstrated that AA is more prevalent in patients with RA in comparison with general population. Future large randomized studies are important to identify cardiovascular- and disease-related risk factors for AA formation in RA patients.

RESUMEN

BACKGROUND: Opioids are considered a cornerstone in the treatment of pain. They are rarely used in almost half of the countries of the world, especially in children. OBJECTIVE: The aim of this study was to assess opioid use over a ten-year study period from 2001-2010, among children 0-18 years old who are members of Clalit Health Services (CHS), the largest HMO in Israel METHODS: Data on the purchase of opioids, authorized for use in Israel, was obtained from the computerized databases of CHS. In addition, the patient's demographic details and cancer morbidity were also extracted. The data was analyzed after all the doses of all opioids consumed (fentanyl patch, oxycodone, methadone, hydromorphone, oral transmucosal fentanyl) were converted into oral morphine equivalents (OME). RESULTS: In all, 1,098 children purchased at least one opioid prescription during the study period. Of them, 27.3% had a diagnosis of cancer and 55.5% were female. A 42% decrease in total annual OME (mg) purchased, from 209,443 mg to 122,048 mg, was observed from 2001 to 2010. There was no specific pattern or trend in the annual number of pediatric and adolescent patients who purchased at least one opioid drug during the study period. In 86.5% of the cases, children with a non-cancer cause of pain purchased opioids for only one month. CONCLUSIONS: There is a low and inconsistent rate of opioid consumption among pediatric and adolescent members of the CHS. Further study is needed to explore the reasons for this low opioid consumption rate in this population group.

RESUMEN

INTRODUCTION: The association between glucose intolerance, elevated blood pressure and abnormal lipid levels is well established and comprises the basis of metabolic syndrome pathophysiology. We hypothesize that abnormal preconception lipid levels are associated with the increased risk of severe pregnancy complications such as preeclampsia and gestational diabetes mellitus. METHODS: We included all singleton deliveries (n = 27,721) of women without known cardiovascular morbidity and preeclampsia and gestational diabetes mellitus during previous pregnancies. Association between preconception low high density lipoprotein cholesterol (HDLc level≤50 mg/dL), high triglycerides (level≥150 mg/dL) and the primary outcome (composite of gestational diabetes mellitus/or preeclampsia) was assessed using Generalized Estimation Equations. RESULTS: Primary outcome of preeclampsia and/or gestational diabetes was observed in a total of 3,243 subjects (11.7%). Elevated triglycerides and low HDLc were independently associated with the primary outcome: with odds ratio (OR) of 1.61 (95% CI 1.29-2.01) and OR = 1.33 (95% CI 1.09-1.63), respectively, after adjusting for maternal age, weight, blood pressure, repeated abortions, fertility treatments and fasting glucose. There was an interaction between the effects of HDLc≤50 mg/dL and triglycerides≥150 mg/dL with an OR of 2.69 (95% CI 1.73-4.19). CONCLUSIONS: Our analysis showed an increased rate of preeclampsia and/or gestational diabetes in women with low HDLc and high triglycerides values prior to conception. In view of the severity of these pregnancy complications, we believe this finding warrants a routine screening for the abnormal lipid profile among women of a child-bearing age.

RESUMEN

Bedside computing may lead to increased hospital-acquired infections mediated by computer input devices handled immediately after patient contact. We compared 2 decontamination methods in 2 types of wards. We found high baseline contamination rates, which decreased following decontamination, but the rates remained unacceptably high. Decontamination was more effective in intensive care units compared with medical wards and when using alcohol-based impregnated wipes compared with quaternary ammonium-based impregnated wipes.

RESUMEN

Coronary atherosclerosis is a progressive disease. We sought to determine whether this fact also applies to patients at an advanced age with normal coronary arteries (NCAs) undergoing repeat catheterization at least 5 years later. Of the 189 patients who were found to have NCAs, 154 (81%) remained with NCAs and 35 (19%) developed obstructive coronary artery disease (OCAD). Development of OCAD was observed at all ages. Isolated risk factors were not associated with the appearance of OCAD, but the combination of diabetes mellitus with age >65 years or with smoking was associated with the appearance of OCAD (P = .04 for both). In conclusion, the finding of angiographically NCAs in elderly individuals does not prevent the later development of OCAD.

RESUMEN

BACKGROUND: To investigate the risk for subsequent cardiovascular events in women having placental abruption during a follow-up period of more than 10 years. METHODS: A population-based study of the incidence of cardiovascular events in women who had placental abruption with women without placental abruption during 1988-99 and with follow-up until 2010. Associations between placental abruption and maternal long-term cardiovascular morbidity and mortality were investigated. Kaplan-Meier survival curves and multivariable Cox regression were used to estimate cumulative incidence of cardiovascular mortality. RESULTS: During the study period, there were 47 585 deliveries meeting the inclusion criteria; of these, 653 occurred in patients with placental abruption. No significant association was noted between placental abruption and subsequent long-term hospitalisations because of cardiovascular causes. However, placental abruption was associated with long-term cardiovascular mortality [odds ratio (OR) = 6.6; 95% confidence interval (CI) 2.3, 18.3]. The cardiovascular case fatality rate for the placental abruption group was 13.0% vs. 2.5% in the comparison group (P < 0.001). Patients with a history of placental abruption had a significantly higher risk for cardiovascular mortality during the follow-up period (Log-rank test P = 0.017). Using Cox multivariable regression models, placental abruption remained an independent risk factor for long-term maternal cardiovascular mortality [adjusted hazard ratio (HR) = 4.3; 95% CI 1.1, 18.6). CONCLUSION: Placental abruption is a significant risk factor for long-term cardiovascular mortality in a follow-up period of more than a decade.

RESUMEN

OBJECTIVE: To investigate whether a diagnosis of gestational diabetes mellitus (GDM) is a risk factor for subsequent long-term cardiovascular morbidity. DESIGN: A population-based study. SETTING: Soroka University Medical Center, a tertiary centre in the southern region of Israel. PATIENTS: A cohort of women with and without a diagnosis of GDM who delivered during the years 1988-1999 with a follow-up period until 2010. INTERVENTIONS: A comparison of the incidence of cardiovascular morbidity. RESULTS: Of 47 909 deliveries that met the inclusion criteria, 4928 (10.3%) occurred in patients who were diagnosed with GDM. During a follow-up period of more than 10 years, compared with women who gave birth at the same time period, after adjustment for age and ethnicity, patients with GDM had higher rates of cardiovascular morbidity including non-invasive cardiac diagnostic procedures (OR=1.8; 95% CI 1.4 to 2.2), simple cardiovascular events (OR=2.7; 95% CI 2.4 to 3.1) and total cardiovascular hospitalisations (OR=2.3; 95% CI 2.0 to 2.5). In a Cox proportional hazards model, adjusted for comorbidities such as pre-eclampsia and obesity, GDM was independently associated with cardiovascular hospitalisations (adjusted HR 2.6, 95% CI 2.3 to 3). CONCLUSIONS: GDM is an independent risk factor for long-term cardiovascular morbidity in a follow-up period of more than a decade.

RESUMEN

BACKGROUND: Opioids are considered a cornerstone in the treatment of cancer pain. OBJECTIVES: To assess opioid use during a 6 year period (2001-2006) among cancer patients served by Clalit Health Services, the largest health management organization in Israel. METHODS: Purchasing data of opioids authorized for use in Israel were obtained from the computerized databases of Clalit for the period 2001-2006. Patients' demographic and cancer morbidity data were extracted. The data were analyzed by translating the purchased opioids (fentanyl patch, oxycodone, buprenorphine, methadone, hydromorphone) to oral morphine equivalents (OME). RESULTS: During the study period 182,066 Clalit members were diagnosed with cancer; 58,443 (32.1%) of them died and 31,628 (17.3%) purchased opioids at least once. In 2001, 7.5% of Clalit cancer patients purchased opioids at least once within 5 years of the initial diagnosis. Between 2002 and 2006 this percentage increased consistently, reaching 9.9% in 2006. The average daily dose of opioids increased from 104.1 mg OME in the year 2001 to 115.2 mg OME in 2006 (11% increase). The average duration of opioid purchasing was 5.0 +/- 8.3 months (range 1-84 months, median 2). During the study period 19,426 cancer patients who purchased opioids at least once died; only 14.3% (3274) were still alive 2 years after their first opioid prescription. CONCLUSIONS: Opioid purchasing increased during the study period, especially during the final months of life. Children (0-18 years old) and elderly male patients (> or = 65 years) began opioid treatment later compared to other age groups. Only a few patients had an opioid early enough to relieve their pain.

RESUMEN

OBJECTIVE: The present study was aimed to evaluate long-term morbidity of patients with hypertensive disorders of pregnancy. STUDY DESIGN: A retrospective cohort study was conducted, including women who gave birth between the years of 1988 to 1998, and had a follow-up until December 2009. Data were extracted by linking a computerized database of hospitalizations with computerized database containing maternal records from the same regional medical center. The exposed group comprised 2072 patients with mild or severe preeclampsia in one or more of their pregnancies and the comparison group included 20742 patients without preeclampsia. Excluded from the study were patients with chronic hypertension and pre-gestational diabetes before the index pregnancy. Data included subsequent hospitalizations in internal medicine, oncology, nephrology, neurology, cardiac intensive care unit, and hematology, as well as a diagnosis of chronic hypertension during the follow-up period. RESULTS: Patients with preeclampsia had significantly higher rates of chronic hypertension diagnosed after the index pregnancy as compared with patients without preeclampsia (12.5% vs. 0.9%; OR = 15.8, 95% CI 12.9-19.3; p < 0.001). Likewise, patients with preeclampsia were more likely to be hospitalized at least once (13.7% vs. 11.4%; OR = 1.2, 95% CI 1.1-1.4; p = 0.002) as compared with patients without preeclampsia. Exposed women had 582 hospitalizations (0.28 hospitalization/patient), while the non-exposed patients had a total of 4687 hospitalizations (0.23 hospitalization/patient; p < 0.001). CONCLUSION: Preeclampsia is a significant risk factor for long-term morbidity such as chronic hypertension and hospitalizations later in life.

RESUMEN

Most studies on safety/risk of drugs in pregnancy consider the proportion of births (but not pregnancy terminations) affected by the drug from all exposed infants. Lack of data on pregnancy terminations could bias results. A computerized database for medications dispensed to pregnant women in southern Israel was linked with records from the district hospital; 84 823 deliveries and 998 medical pregnancy terminations took place; 571 of the women were exposed to folic acid antagonists in the first trimester. When only births were examined, there was no association between folic acid antagonists and fetal malformations. When data on pregnancy terminations were examined and births and pregnancy terminations were combined, there was a significant risk (neural tube defects: odds ratio 18.83, 95% confidence interval 9.24-38.37; cardiovascular defects: odds ratio 3.86, 95% confidence interval 1.67-8.88; and neural tube defects: odds ratio 6.30, 95% confidence interval 3.34-9.15; cardiovascular defects: odds ratio 1.76, 95% confidence interval 1.05-2.92, respectively). Inclusion of only birth data in observational studies of drugs in pregnancy constitutes a source of bias toward the null hypothesis.
