ABSTRACT: The goal of this study was to investigate the willingness of Medical Reserve Corps (MRC) volunteers to participate in public health emergency-related activities by assessing their attitudes and beliefs. MRC volunteers responded to an online survey organized around the Extended Parallel Process Model (EPPM). Respondents reported agreement with attitude/belief statements representing perceived threat, perceived efficacy, and personal/organizational preparedness in 4 scenarios: a weather-related disaster, a pandemic influenza emergency, a radiological ("dirty bomb") emergency, and an inhalational anthrax bioterrorism emergency. Logistic regression analyses were used to evaluate predictors of volunteer response willingness. In 2 response contexts (if asked and regardless of severity), self-reported willingness to respond was higher among those with a high perceived self-efficacy than among those with low perceived self-efficacy. Analyses of the association between attitude/belief statements and the EPPM profiles indicated that, under all 4 scenarios and with few exceptions, those with a perceived high threat/high efficacy EPPM profile had statistically higher odds of agreement with the attitude/belief statements than those with a perceived low threat/low efficacy EPPM profile. The radiological emergency consistently received the lowest agreement rates for the attitude/belief statements and response willingness across scenarios. The findings suggest that enrollment with an MRC unit is not automatically predictive of willingness to respond in these types of scenarios. While MRC volunteers' self-reported willingness to respond was found to differ across scenarios and among different attitude and belief statements, the identification of self-efficacy as the primary predictor of willingness to respond regardless of severity and if asked highlights the critical role of efficacy in an organized volunteer response context.

ABSTRACT: Readmission reduction is at the focus of health care systems worldwide in efforts to improve efficiency across care settings. Yet, setting targets for readmission reduction is complicated due to inconsistencies in evidence pointing to effective organization-wide interventions and because of inverse incentives (such as maintaining high occupancy rates). Nonetheless, readmission reduction is one of the few quality measures that, if implemented properly, can serve as a catalyst for system integration. Appropriate mechanisms should be applied to hospitals as well as ambulatory settings to ensure that accountability is assigned to all stakeholders.

ABSTRACT: BACKGROUND: During the 1990s, Israel absorbed approximately 1 million immigrants. The entitlement to citizenship and social rights in a country with universal health care coverage makes the Israeli case of special interest concerning immigrants' utilization of health care services. OBJECTIVES: 1. To describe utilization patterns of emergency room and in-hospital services among recent immigrants to Israel. 2. To determine if and when there is convergence of health care utilization patterns on the part of recent immigrants with native-born and long-established immigrants to Israel. METHODS: Data was obtained from Clalit Health Services computerized database and included sociodemographics, date of immigration,presence of chronic disease, emergency room visits, and hospitalization days among all covered residents.Descriptive analysis of the group characteristics, multivariate analyses to determine influential factors, and tests for trend were conducted. RESULTS: Rates of emergency room and hospitalization were lower for immigrants, and remained so even after 10 years. CONCLUSIONS: Economic and cultural factors influence health care utilization among immigrants and may lead to inequity in health care delivery and consequent health outcomes. A better understanding is needed for the differences in health care utilization patterns between immigrants and veteran Israelis.

ABSTRACT: BACKGROUND: A national program of a 2-dose universal childhood MMR vaccination policy has been in effect in Israel since 1988. As the 1988 birth cohort reached fertility age, questions regarding immunity against rubella were raised. OBJECTIVE: To assess the seroprevalence of rubella IgG antibodies among young Israeli adults born after 1987 in comparison to previous birth cohorts, in order to determine evidence based policy for prevention of rubella and congenital rubella syndrome. METHODS: We conducted a seroprevalence study of rubella IgG antibodies among 416 Israeli adults (42.5% females) born in 1988-1989, based on a representative sample of sera collected at age 18-19 upon recruitment to mandatory military service in 2007. RESULTS: In total, 87.7% were seropositive (>15IU/ml) as compared with 84.8% in the 1999 recruitment (P=0.26) and 93.4% in 1987 (P=0.004). Yet there was a difference by gender. The proportion of seropositives among female young adults (92.7%) was significantly lower as compared to those measured in the 1999 (99.2%, P=0.001) and 1987 (99.0%, P=0.006) recruitments. The proportion of seropositives among males (84.1%) was significantly higher as compared to those measured in 1999 (73.0%, P<0.001) but similar to those of 1987 (88.8%, P=0.13). Females born in the FSU were found to be high risk groups as 11.5% were seronegative. CONCLUSIONS: Our findings indicate that despite a successful program of congenital rubella syndrome prevention in Israel, there is a decline in seroprevalence among female young adults, especially immigrants from the FSU. A proactive catch-up program for females, especially for those of higher risk for susceptibility should be considered in Israel and in other countries.

ABSTRACT: PURPOSE: To assess the seroprevalence and seroconversion of Epstein-Barr virus (EBV) and cytomegalovirus (CMV) Immunoglobulin G (IgG) antibodies and identify associated socioeconomic and smoking variables among male young adults in Israel, to explore health disparities and aid prevention efforts. METHODS: A population-based seroprevalence study of EBV and CMV IgG antibodies in a systematic sample of Israeli males upon recruitment to mandatory military service during 1994-2004. Associations between socioeconomic and smoking variables and the seroprevalence of EBV/CMV were evaluated, controlling for possible confounders. A subset of seronegative subjects was assessed for seroconversion upon discharge from military service. RESULTS: Overall seroprevalence rates were 87% for EBV and 59% for CMV. An association between the seroprevalence of EBV and CMV was observed. Seroconversion was 56% for EBV as compared with 31% for CMV. Lower paternal education was found to be associated with both EBV and CMV seroprevalence. Lower socioeconomic status, North African origin, and urban residence were found to be associated with CMV seropositivity, as was smoking for EBV seropositivity. CONCLUSIONS: Socioeconomic disparities exist in the seroprevalence rates of CMV and EBV among Israeli male young adults. The results of the study could aid public health efforts and determine target populations when a vaccine becomes available.

ABSTRACT: The all-hazards willingness to respond (WTR) of local public health personnel is critical to emergency preparedness. This study applied a threat-and efficacy-centered framework to characterize these workers' scenario and jurisdictional response willingness patterns toward a range of naturally-occurring and terrorism-related emergency scenarios.
Eight geographically diverse local health department (LHD) clusters (four urban and four rural) across the U.S. were recruited and administered an online survey about response willingness and related attitudes/beliefs toward four different public health emergency scenarios between April 2009 and June 2010 (66% response rate). Responses were dichotomized and analyzed using generalized linear multilevel mixed model analyses that also account for within-cluster and within-LHD correlations.
Comparisons of rural to urban LHD workers showed statistically significant odds ratios (ORs) for WTR context across scenarios ranging from 1.5 to 2.4. When employees over 40 years old were compared to their younger counterparts, the ORs of WTR ranged from 1.27 to 1.58, and when females were compared to males, the ORs of WTR ranged from 0.57 to 0.61. Across the eight clusters, the percentage of workers indicating they would be unwilling to respond regardless of severity ranged from 14-28% for a weather event; 9-27% for pandemic influenza; 30-56% for a radiological 'dirty' bomb event; and 22-48% for an inhalational anthrax bioterrorism event. Efficacy was consistently identified as an important independent predictor of WTR.
Response willingness deficits in the local public health workforce pose a threat to all-hazards response capacity and health security. Local public health agencies and their stakeholders may incorporate key findings, including identified scenario-based willingness gaps and the importance of efficacy, as targets of preparedness curriculum development efforts and policies for enhancing response willingness. Reasons for an increased willingness in rural cohorts compared to urban cohorts should be further investigated in order to understand and develop methods for improving their overall response.

ABSTRACT: Data on utilization of ambulatory care and the impact of lifestyle on health among young adults are scarce. Israeli mandatory military service provides a unique opportunity to investigate these topics. Study objective was to analyze the utilization of health care services (HCS) during the first year of military service, and its associations with health behavior at recruitment, in order to plan health services, health classification, and health promotion activities.
We conducted a retrospective cohort study among a representative sample of 5,751 mandatory new recruits between January 1, 2004, and December 31, 2008. Data were collected from the Israeli Defense Force computerized medical and administrative records and from an ongoing health survey among military recruits.
During their first year of service, recruits had, on average, more than 7 visits to the primary care clinic, more than 10 dispensed nonchronic medications, and more than 5 days of sick leave. Female sex (OR = 1.27; 1.06-1.51) and current cigarette smoking (OR = 1.57; 1.34-1.84) were significantly associated with increased use of HCS, after controlling for possible confounders.
Our findings indicate high utilization of HCS during the first year of military service and highlight the potential effect of cigarette smoking as a risk factor for increased morbidity among apparently healthy young adults. These findings support adding smoking status to fitness assessments and could aid health promotion efforts to reduce smoking rates among adolescents.

ABSTRACT: To evaluate patient and physician characteristics associated with the type of psychotropic medications (anti-anxiety, antidepressant, or both) purchased.
The Clalit Health Care Services is the largest managed care health fund in Israel, a country that employs a universal healthcare system. We randomly sampled 30,000 primary care patients over the age of 22 as of January, 2006.
Overall, 2,217 purchased either antidepressant or antianxiety medications at least once during the year 2006 and had no prior purchases during the last quarter of 2005. The majority (1,518; 68.4%) purchased only anti-anxiety medications and as many as 264 (12%) purchased both anti-anxiety and antidepressant medications. The remaining 435 (19.6%) patients purchased only antidepressant medications. Physician level characteristics explained only a small portion of the variance and, thus, were not included in further analysis. Several patient level characteristics, including age, somatic, and psychiatric diagnosis were associated with the purchase of different types of medications.
Contrary to clinical guidelines, the purchase of anti-anxiety medications is more prevalent than the purchase of antidepressant medications. In a managed care setting, patient characteristics have a greater role in determining purchasing patterns than provider characteristics; potentially, because of the managed care characteristics that actively guide the care provided to patients.

ABSTRACT: Outbreaks and sporadic cases of pneumococcal illness occur among young adults in confined settings. Our aim was to characterize pneumococcal acquisition and carriage among healthy young adults in Israel during military training in confined settings.
During the years 2007-2008, an observational longitudinal study was conducted in three cohorts of healthy soldiers, during a 7-month basic training period. Epidemiological data, oropharyngeal and nasopharyngeal cultures were sampled on 5 occasions: before and 3, 6, 12 and 24 weeks after start of training. Samples were processed within 2-18 hours. Relatedness of isolates was investigated by capsular typing of all isolates and pulsed-field gel electrophoresis to determine acquisition and transmission. Carriage and acquisition patterns were analyzed and multivariable logistic regression analysis was performed to assess the impact of time on acquisition after mixing, controlling for other covariates.
Pneumococci were recovered on 202 of 1872 visits among 742 individuals, including 40 different serotypes. Mean carriage prevalence increased in all visits following training initiation. Acquisition during training was high, as 36.9% of individuals acquired pneumococci at least once during training, and for almost one fourth of the whole population this occurred during the first 6 weeks. Significant clustering was noted. Sharing drinking glass/bottle was found to be a significant and common risk factor for pneumococcal acquisition.
Pneumococcal acquisition is highly frequent when young adults live in close contact in confined settings, especially early after mixing.

ABSTRACT: Introduction of new private, voluntary immunizations often results in low vaccine uptake among certain sub-groups within the population. Revealing factors associated with underimmunization is crucial in vaccine endorsement and distribution.
Our goal was to investigate the effect of child's birth order on private voluntary varicella vaccination.
A nested case-control study was conducted on a cohort of 110,902 Israeli children under the age of 5 years. We compared social and demographic factors of immunized and unimmunized participants. Logistic regression models were built to examine the association between birth order and vaccination, controlling for child's age, gender, country of birth, ethnicity, parents' country of birth, area of residence, and socioeconomic status (SES).
Ethnicity had the highest association with varicella immunization status. The odds of vaccination in the general Jewish and Ultra-Orthodox Jewish populations were 25.55- (95%CI:20.13;32.42) and 15.04- (95%CI:10.18;22.22) times the odds in Arab population, respectively. Child's birth order was inversely related to vaccination status and presented a nonlinear exposure-response relationship. This relationship was maintained in different ethnicity and SES groups. Child's birth order was associated with vaccination differently in large (> 3 siblings) and small to average-sized sibships (≤ 3 siblings). Other parameters associated with vaccination were child's and parents' country of origin, area of residence and SES.
Birth order is an independent risk factor for underimmunization, associated with child's vaccination status beyond economic, social, and demographic parental characteristics.

ABSTRACT: This study evaluated patients' and physicians' characteristics associated with the purchase of benzodiazepines by older primary care patients in Israel. The analytic sample consists of those 6,421 patients age 65 and older. We used multi-level analysis with whether or not benzodiazepines were purchased at least once between June 2005 and 2007 as an outcome. We also evaluated patients' and physicians' characteristics associated with the purchase of benzodiazepines for 6 months or longer. Almost half the sample (41.5%) purchased benzodiazepines at least once during the study period and more than half (54.5%) of those purchasing benzodiazepines had a continued purchase for 6 months or longer. Physicians' characteristics explained only a small portion of the variance associated with purchasing, whereas patients' demographic and clinical characteristics were associated with purchasing. Any intervention to improve the use of benzodiazepines should be directed at both patients and physicians.

ABSTRACT: Vaccines are a cornerstone in any pandemic influenza preparedness plan. Successful supplementary mass vaccination programs require proper advance planning. We aimed to identify general, and Israeli specific, challenges and opportunities before initiating the Israeli pandemic influenza vaccination program in order to better plan implementation of the program. Following the vaccination campaign the analysis was retrospectively examined in order to determine whether the challenges were properly identified and whether the opportunities were indeed realized. The major challenges identified were prioritization; ongoing communication with the public; balancing between central management and accessibility; and preventing vaccination errors. The major opportunity was expected to be the chance to enhance cooperation and communication between different organizations both within and outside of the health system at local, national and international levels. The vaccination program was planned based on this analysis. In retrospect, the analysis identified the key challenges and opportunities and appropriate measures were taken. However, the criticalness of acceptance of the vaccine among health care practitioners was not given sufficient attention and should be addressed in future vaccination programs. Analysis of global and local challenges and opportunities served as a useful tool for planning a pandemic influenza vaccination program. Lessons learned from this analysis could serve to foster cooperation and communication between various agencies in the event of planning rapid mass vaccination programs as well as for more routine public health vaccination campaigns.

ABSTRACT: In March 2010 the United States enacted the most significant health care reform in several decades. The Patient Protection and Affordable Care Act, amongst other provisions, addresses two of the main current shortcomings of the U.S. health system: the large portion of the population that are uninsured and the high percentage of hsealth expenditures (mostly private] which amounts to about 16% of the GDP. Changes to the current structure and financing of the U.S. health system will have implications for other health systems, for science (e.g., through enhanced federal funding for comparative effectiveness research), and for technological advance (e.g., through accelerated development and use of electronic health records). There are several lessons from the reform, and the factors leading to its implementation, for the Israeli health system. Firstly, the basic principles of the Israeli health system are a source of pride, and undermining its main values can have deleterious effects. Overreliance on private, out-of-pocket, spending and lack of support for public practice of medicine (in community and hospital settings) will weaken the public sector, strengthen the private sector, and could result in a tiered lower quality and less accessible public system with greater widening of gaps in health and health care utilization. This paper reviews the main provisions of the U.S. health care reform and the potential implications for the IsraeLi health system.

ABSTRACT: The ability to accurately detect differential resource use between persons of different socioeconomic status relies on the accuracy of health-needs adjustment measures. This study tests different approaches to morbidity adjustment in explanation of health care utilization inequity.
A representative sample was selected of 10 percent (~270,000) adult enrolees of Clalit Health Services, Israel's largest health care organization. The Johns-Hopkins University Adjusted Clinical Groups® were used to assess each person's overall morbidity burden based on one year's (2009) diagnostic information. The odds of above average health care resource use (primary care visits, specialty visits, diagnostic tests, or hospitalizations) were tested using multivariate logistic regression models, separately adjusting for levels of health-need using data on age and gender, comorbidity (using the Charlson Comorbidity Index), or morbidity burden (using the Adjusted Clinical Groups). Model fit was assessed using tests of the Area Under the Receiver Operating Characteristics Curve and the Akaike Information Criteria.
Low socioeconomic status was associated with higher morbidity burden (1.5-fold difference). Adjusting for health needs using age and gender or the Charlson index, persons of low socioeconomic status had greater odds of above average resource use for all types of services examined (primary care and specialist visits, diagnostic tests, or hospitalizations). In contrast, after adjustment for overall morbidity burden (using Adjusted Clinical Groups), low socioeconomic status was no longer associated with greater odds of specialty care or diagnostic tests (OR: 0.95, CI: 0.94-0.99; and OR: 0.91, CI: 0.86-0.96, for specialty visits and diagnostic respectively). Tests of model fit showed that adjustment using the comprehensive morbidity burden measure provided a better fit than age and gender or the Charlson Index.
Identification of socioeconomic differences in health care utilization is an important step in disparity reduction efforts. Adjustment for health-needs using a comprehensive morbidity burden diagnoses-based measure, this study showed relative underutilization in use of specialist and diagnostic services, and thus allowed for identification of inequity in health resources use, which could not be detected with less comprehensive forms of health-needs adjustments.

ABSTRACT: A recent mumps outbreak in Israel despite an ongoing national program of a 2-dose universal childhood vaccination policy since 1988, raised questions regarding population immunity among young adults.
To assess the seroprevalence of mumps antibodies among young Israeli adults born after 1987 in order to determine evidence based vaccination policy.
We conducted a seroprevalence study of mumps IgG antibodies among 441 Israeli adults born in 1988-9, based on a representative sample of sera collected upon recruitment to mandatory military service in 2007.
The overall seroprevalence of IgG antibody to mumps virus among 1988-9 born was 83.7%, 82.1% among males and 85.7% among females. Seroprevalence among 2007 recruits was similar to 1999 recruits (83.3%, P=0.89) and significantly lower than 1987 recruits (94.1%, P<0.0001). The absolute decrease between 2007 and 1987 for males was 13.1% (P<0.0001) and for females 7.0% (P=0.02). Seroprevalence was not significantly higher among native Israelis (84.9%) than among young adults born in the Commonwealth of Independent States (81.1%, P=0.46) and significantly higher compared to young adults born in Western Europe or North America (68.2%, P=0.045).
Our findings indicate sub-optimal population seroprevalence despite a 2-dose universal childhood vaccination policy. This study allows better understanding of current mumps outbreaks in Israel and elsewhere following periods of low circulation of wild virus. These findings support mumps vaccination, even for populations and individuals that received two doses during childhood, as means for outbreak containment among young adults, especially in crowded settings, and serve as a reminder to the need for dynamic vaccination policy, supported by health promotion activities.

ABSTRACT: To describe an organization-wide disparity reduction strategy and to assess its success in quality improvement and reduction of gaps in health and health care.
Clalit Health Services, Israel's largest non-for-profit insurer and provider serving 3.8 million persons.
Before and after design: quality assessment before and 12-month postinitiation of the strategic plan. A composite weighted score of seven quality indicators, measuring attainment of diabetes, blood pressure, and lipid control, lack of anemia in infants, and performance of mammography, occult blood tests, and influenza vaccinations.
Quality indicator scores, derived from Clalit's central data warehouse, based on data from electronic medical records.
Low-performing clinics, of low-socioeconomic and minority populations, were targeted for intervention. Twelve months after the initiation of the project continuous improvement was observed coupled with a reduction of 40 percent of the gap between disadvantaged clinics, serving ~10 percent of enrollees, and all other medium-large clinics.
The comprehensive strategy, following a quality improvement framework, with a top-down top-management incentives and monitoring, and a bottom-up locally tailored interventions, approach, is showing promising results of overall quality improvement coupled with disparity reduction in key health and health care indicators.

ABSTRACT: Terrorist use of a radiological dispersal device (RDD, or "dirty bomb"), which combines a conventional explosive device with radiological materials, is among the National Planning Scenarios of the United States government. Understanding employee willingness to respond is critical for planning experts. Previous research has demonstrated that perception of threat and efficacy is key in the assessing willingness to respond to a RDD event.
An anonymous online survey was used to evaluate the willingness of hospital employees to respond to a RDD event. Agreement with a series of belief statements was assessed, following a methodology validated in previous work. The survey was available online to all 18,612 employees of the Johns Hopkins Hospital from January to March 2009.
Surveys were completed by 3426 employees (18.4%), whose demographic distribution was similar to overall hospital staff. 39% of hospital workers were not willing to respond to a RDD scenario if asked but not required to do so. Only 11% more were willing if required. Workers who were hesitant to agree to work additional hours when required were 20 times less likely to report during a RDD emergency. Respondents who perceived their peers as likely to report to work in a RDD emergency were 17 times more likely to respond during a RDD event if asked. Only 27.9% of the hospital employees with a perception of low efficacy declared willingness to respond to a severe RDD event. Perception of threat had little impact on willingness to respond among hospital workers.
Radiological scenarios such as RDDs are among the most dreaded emergency events yet studied. Several attitudinal indicators can help to identify hospital employees unlikely to respond. These risk-perception modifiers must then be addressed through training to enable effective hospital response to a RDD event.

ABSTRACT: Objectives: To evaluate patient and physician characteristics associated with the purchase of antidepressant medication for at least 6 months.
Clalit Health Services is the largest managed care health fund in Israel, a country that uses a universal healthcare system. We randomly sampled 30,000 primary care patients over the age of 22 years. Our analytic sample consisted of those 949 patients who did not purchase antidepressant medication during the last quarter of 2005 and purchased antidepressant medication at least once in 2006. We used multilevel analysis, with whether or not medication was purchased for at least 6 months as an indicator of adherence. Patient and physician characteristics were evaluated as potential predictors.
Only 23% of the sample was classified as adherent. Physician characteristics explained only a small portion of the variance in adherence and, as a result, were not included in multivariate analysis. Patients who did not have a somatic diagnosis, had a depression diagnosis, and were of higher socioeconomic status were more likely to be classified as adherent. Patients who purchased tricyclic antidepressants were less likely to be classified as adherent.
The findings suggest that in a managed care setting, there is high uniformity among physicians. Although physician characteristics explain little of the variability associated with adherence, certain patient characteristics as determined by their physicians (eg, antidepressant drug class, psychiatric diagnosis) do play a role in adherence.

ABSTRACT: Equitable distribution of healthcare resources and fair assessments of providers' performance necessitates adjusting for case-mix. The feasibility and validity of applying case-mix measures, based on inpatient and outpatient diagnoses, has yet to be tested in Israel.
Assessment of the feasibility and validity of applying the Johns-Hopkins University Adjusted Clinical Groups (JHU-ACG) case-mix system, using diagnoses from hospitalizations or physician visits, at Clalit Health Services (CHS).
A representative sample of 117,355 enrollees during 2006. The distribution of ACG morbidity groups and relative resource weights in CHS and the degree to which it corresponds to ACGs' distribution in other countries was examined. The degree to which ACGs can explain utilization of primary and specialty care in CHS was determined.
ACGs explained a large percent of the variance in primary care and specialist visits (R2 = 38-54%), better than age and gender alone (R2 =12-13%). A high degree of correlation was found between the distribution of the population into ACG groups in CHS and samples from Canada or the United States (r = 0.91), and between the relative resource use for each ACG at CHS compared to the Canadian and US samples (r = 0.78-0.98).
The JHU-ACG case-mix system can be applied in the Largest healthcare organization in Israel based on diagnoses generated at hospitalizations and physician visits. The system can now be applied for a variety of purposes, including resource allocation according to medical need, and for conducting fair assessments of providers' performance, which are currently being tested by CHS.

ABSTRACT: To investigate prospectively the effects of vigor at work on the end points of mortality and the prevalence of ischemic heart disease (IHD) and diabetes.
We tested the hypothesized beneficial effects of feeling vigorous at work at baseline on the risks of all-cause mortality, IHD, and diabetes during a 20-year follow-up. Participants were healthy employees (n = 968) who underwent a routine health check at baseline. We calculated the risk of all-cause mortality, IHD, and diabetes, with days as the time scale, using the Cox proportional hazard model. In our analyses, we predicted the above end points by baseline vigor, age, gender, and educational level, adjusting for the physiological risk factors of total cholesterol, glucose, and body mass index, the behavioral risk factors of smoking, alcohol intake, and physical activity, and the psychological risk factors of depressive and anxiety symptoms.
As hypothesized, we found that, after the above adjustments, baseline vigor decreased the risk of follow-up mortality by 26% (hazard ratio, 0.74; 95% confidence interval, 0.58-0.95) and the risk of diabetes by 17% (hazard ratio, 0.83; 95% confidence interval, 0.68-0.98). However, vigor did not have a significant effect on the risk of IHD.
Independently of physiological, behavioral, and psychological risk factors, feeling vigorous at work protected the participants from diabetes and reduced their risk of mortality.
