Purpose: The abundant use of antibiotics (Abs) in the community plays a major role in inducing Ab resistance, but the literature concerning patterns in outpatient Ab use is limited. This study aims to lay the foundations for future policy and interventional programs to address the rise in Ab resistance by looking at long-term trends in Ab usage in Israel. Methods: Defined daily doses per 1,000 inhabitants per day (DID) of total Ab use, consumption in different age groups, and of different Ab preparations were calculated for the years 2000, 2005, and 2010 in the eight districts of Israel. Data were collected from the pharmacy registries of 'Clalit Health Services', the largest Health Maintenance Organization (HMO) in Israel, covering 4 million patients, representing 53 % of the population. Trends in use over time were analyzed. Results: The overall Ab usage in Israel has remained constant in the last decade. Three significant trends were identified in this study: an increase in the consumption of expensive, broad-spectrum Abs, paralleled by a reduction in narrow-spectrum Abs; an increase in Ab consumption among the elderly, counteracted by reduced usage among children; large regional variations in the overall and specific use of Ab agents. Conclusions: Our main findings of increased broad-spectrum Ab consumption, primarily among the adult population in Israel, and a wide variability in Ab use between the regions in Israel, can focus our future studies on searching for the factors behind these trends to aid in constructing interventional methods for decreasing outpatient Ab overuse.

Objective: The aims of this study were to evaluate the prevalence of metabolic syndrome (MetS) in psoriatic arthritis (PsA) patients according to the most recent definition in a Mediterranean population and to determine its association with biomarkers of inflammation and serum adipocytokine levels., Methods: Demographic, clinical, and laboratory data were collected on 74 patients with PsA and 82 control subjects. The presence of MetS was determined according to the current "harmonization" definition. Serum adipocytokines were analyzed. Continuous variables were compared by t test and discrete variables by χ test. Multivariate regression models compared the association between the presence of MetS and the blood levels of adipocytokines., Results: The prevalence of MetS was higher in PsA patients compared with the control group: 54.8% versus 36.6%, respectively (P = 0.02; odds ratio, 2.33; 95% confidence interval, 1.16-4.69). The main difference between the 2 groups was waist circumference. No association was found between MetS and parameters of articular and skin disease activity or treatment. Leptin levels and leptin/adiponectin ratio were higher in PsA patients compared with control subjects: 83.4 versus 51.7 ng/mL (P = 0.001) and 6.3 × 10 versus 4.1 × 10 (P = 0.015), respectively. There was no significant difference in the adiponectin levels between the groups., Conclusions: The prevalence of MetS was higher in PsA patients compared with non-PsA control subjects in this Mediterranean population. Clinicians caring for PsA patients ought to be aware of the increased risk of MetS in PsA patients, confirmed in different regions worldwide. The increased MetS seems to be linked to central obesity in these patients, and appropriate treatment recommendations are advised.

Introduction: The southern district of Clalit Health Services and Soroka University Medical Center are combined in an organizational configuration: the Southern Region. The Region has developed joint programs in order to advance the quality of medical care whilst optimizing the utilization of available resources. An objective continuous method of assessment was needed to evaluate the continuity of care between the community and the hospital., Aims: To produce objective tools for quantification based on pre-existing data systems, which enable ongoing assessment of the quality of continuity of care between the community and hospital, and the impact of the introduction of novel means of improvement., Methods: We defined a set of measurements that exemplify continuity of care in different areas of transition between community and hospital, all directly retrievable from existing computerized data sources., Results: About forty different measurements have been defined, in different clinical areas. Of these, a dozen have already been implemented by mapping the process and the main obstacles that the patient goes through, followed by implementation of appropriate solutions., Conclusions: The application of an objective system of assessment of the results of continuity of care, utilizing pre-existing data sources, is essential for advancing the initiative, and is a breakthrough in the quantification of continuity of care., Discussion: Continuity of care between community and hospital has been applied in the Southern Region to dozens of quality measurements. This is a novel project developing an objective system of measurement, directly assessing the quality of continuity of care for the individual patient.

Objective: To assess a quality improvement disparity reduction intervention and its sustainability., Data Sources/study Setting: Electronic health records and Quality Index database of Clalit Health Services in Israel (2008-2012)., Study Design: Interrupted time-series with pre-, during, and postintervention disparities measurement between 55 target clinics (serving approximately 400,000 mostly low socioeconomic, minority populations) and all other (126) clinics., Data Collection/extraction Methods: Data on a Quality Indicator Disparity Scale (QUIDS-7) of 7 indicators, and on a 61-indicator scale (QUIDS-61)., Principal Findings: The gap between intervention and nonintervention clinics for QUIDS-7 decreased by 66.7 percent and by 70.4 percent for QUIDS-61. Disparity reduction continued (18.2 percent) during the follow-up period., Conclusions: Quality improvement can achieve significant reduction in disparities in a wide range of clinical domains, which can be sustained over time., (© Health Research and Educational Trust.)

Background: Readmission prevention should begin as early as possible during the index admission. Early identification may help target patients for within-hospital readmission prevention interventions., Objectives: To develop and validate a 30-day readmission prediction model using data from electronic health records available before the index admission., Research Design: Retrospective cohort study of admissions between January 1 and March 31, 2010., Subjects: Adult enrollees of Clalit Health Services, an integrated delivery system, admitted to an internal medicine ward in any hospital in Israel., Measures: All-cause 30-day emergency readmissions. A prediction score based on before admission electronic health record and administrative data (the Preadmission Readmission Detection Model-PREADM) was developed using a preprocessing variable selection step with decision trees and neural network algorithms. Admissions with a recent prior hospitalization were excluded and automatically flagged as "high-risk." Selected variables were entered into multivariable logistic regression, with a derivation (two-thirds) and a validation cohort (one-third)., Results: The derivation dataset comprised 17,334 admissions, of which 2913 (16.8%) resulted in a 30-day readmission. The PREADM includes 11 variables: chronic conditions, prior health services use, body mass index, and geographical location. The c-statistic was 0.70 in the derivation set and of 0.69 in the validation set. Adding length of stay did not change the discriminatory power of the model., Conclusions: The PREADM is designed for use by health plans for early high-risk case identification, presenting discriminatory power better than or similar to that of previously reported models, most of which include data available only upon discharge.

Background: After a decade of extensive use, the actual contribution of bevacizumab in first-line treatment of metastatic colorectal cancer (mCRC) is still unclear., Objective: To evaluate 'real-life' outcomes of patients with mCRC before and after the introduction of bevacizumab to standard mCRC first-line practice., Methods: Using the computerized administrative database of Clalit Health Services' (CHS), Israel's largest health care provider, we retrospectively compared two cohorts (n = 1739): (A) all CHS' patients diagnosed with mCRC between January 2000 and December 2004 that received first-line irinotecan or oxaliplatin-based combination chemotherapy (before bevacizumab was introduced) (n = 1052), and (B) all patients that started first-line irinotecan or oxaliplatin combination chemotherapy together with bevacizumab between September 2006 and December 2009 (after bevacizumab was fully reimbursed in Israel for mCRC first-line therapy) (n = 687). The primary endpoint was overall survival (OS) and secondary endpoints were first-line progression-free survival (PFS) and metastatectomy rates., Results: Median OS was longer in Cohort B than in Cohort A [23.0 months vs.15.0, adjusted hazard ratio (HR), 0.75]. Secondary outcomes were also better; PFS of 14.0 months vs. 9.8 in the earlier period (HR, 0.75) and metastatectomy rate of 8.1% versus 3.9%. The longer OS in Cohort B was preserved even after controlling for latter-line epidermal growth factor receptor (EGFR) inhibitor use (HR = 0.77)., Conclusion: In this analysis, OS, PFS and metastatectomy rates of first-line treatment of mCRC were significantly higher in the later period of the study. These results, derived from 'real-life' practice, suggest that the use of bevacizumab, among other alterations in the clinical management of mCRC between the two periods, might have had a significant contribution to these outcomes, and may therefore support the current practice of adding bevacizumab to first-line treatment of mCRC.

Background: Elderly patients are at a higher risk of acquiring sepsis, and are largely being treated in Internal Medicine (IM) departments., Aim: To characterize the differences between nonagenarians and other age groups in patients admitted to IM departments with sepsis, and to assess predictors for survival in patients older than 90 years of age., Design and Methods: A prospective registry of all-comers with sepsis admitted to IM departments in a community-based Medical Center was build. Patients' demographics, medical history, clinical presentation and outcomes were recorded and analyzed according to age groups., Results: One thousand and eighty patients were followed for a mean of 83.63 ± 65.90 days. Nonagenarians constituted 10.93% (118/1080) of our cohort. Of these, 70.48% had a cognitive impairment and 82.60% had reduced functional state. Of these, 5.61 and 10.50% fulfilled the criteria of septic shock and severe sepsis, respectively. Sepsis category was significantly influenced by age groups (P < 0.001). Complications secondary to sepsis at admission and throughout hospitalization, and mortality rates, were higher in the nonagenarian population (61.86 vs. 51.14%, P = 0.032 and 37.29 vs. 20.06%, P < 0.001, respectively), and overall survival was significantly lower in the nonagenarian population (40.68 vs. 66.84%, P < 0.001)., Conclusion: Patients treated in IM departments for sepsis are old, and a significant percentage is older than 90 years of age with reduced function and mental status at baseline. These frail patients are afflicted by a worse outcome, which is most likely associated with poor functional status at baseline and severe deconditioning during the acute illness. Prognostic tools are needed to address today's trends in patient-mix and disease severity, specifically for very-old patients admitted with sepsis cared for in IM departments.

Background: Sepsis is prevalent in internal medicine (IM) departments. Elderly patients with sepsis and chronic medical conditions are at an increased risk for venous thromboemolism (VTE). The objective of this study was to assess the rate of VTE and the accuracy of the Padua Prediction Score (PPS) to predict VTE in patient with sepsis admitted to IM departments., Methods: We prospectively collected data on septic patients admitted to IM departments in a community-based medical center. Additionally, we retrospectively collected VTE risk factors and events throughout a 1-year post hospitalization period. We computed the PPS for every patient, and analyzed the data accordingly., Results: In total, 1080 patients were included in the study. The mean age was 74.68 ± 16.1 years. The average PPS was 4.86 ± 2.26, and 71.2% of the patients had a positive PPS. Only 17.8% of the patients received anticoagulant prophylaxis during their hospital stay. Seven patients had VTE on admission, 14 (1.29%) acquired in-hospital VTE, and 7 (0.65%) had VTE post discharge throughout 1 year. In all, 21.9% patients died during hospitalization, and the overall survival rate was 64%. PPS was not correlated with anticoagulant administration (P = 0.36), in-hospital VTE (P = 0.23) or 1-year VTE (P = 0.40), but was significantly associated with in-hospital death and survival (P < 0.0001)., Conclusion: The rate of VTE in medical patients with sepsis in IM departments is low, and PPS lacks granularity in detecting patients at risk of acquiring it. In this population, a positive PPS is highly associated with death, and may reflect a more general co-morbidity and disease severity index., (© 2012 International Society on Thrombosis and Haemostasis.)

Technological advances combined with the aging of the population bring about an increasingly growing number of patients with chronic conditions and multi-morbidity. Multi-morbidity, the co-occurrence of chronic and/or non-chronic conditions in an individual, is the norm among elderly patients, and is becoming increasingly common among younger adults. The Israeli health system, like other systems worldwide, is faced with the challenges posed by the increase in complex multi-morbidity, in an era of growing fiscal constraints, a situation that can induce financial and organizational crises. To effectively cope with such circumstances, a paradigm shift is needed. Health systems need to focus on overall morbidity burden and multi-morbidity (rather than the prevailing one disease at a time approach) and on better care integration. The Israeli health system entails many of the essential elements for addressing the challenges of integrated care, including universal health coverage and advanced health information technology systems. Yet, like other health systems, there is a need for care management support mechanisms that are more effectively tailored to meet the needs of the highly multimorbid patients. This review outlines the organizational approach required to better align care for the main customers of health care in the 21st century: patients with multi-morbidity. We focus on four domains: assessment of morbidity burden according to measures that account for the interaction and synergism amongst conditions; integration across the care continuum; enhancement of primary care and self-management support approaches; and provision of uniquely tailored care management solutions for the highest risk multi-morbid patients.

Disease patterns and manifestations may vary among different populations and change over time. The purpose of our study was to define the demographic, clinical, roentgenologic, and laboratory findings in a recent cohort of psoriatic arthritis patients followed up in rheumatology clinics in northern Israel. We conducted a cross-sectional study of 149 psoriatic arthritis patients. Demographic, clinical, laboratory, and radiological data, with emphasis on the pattern of arthritis, treatment regimens, and co-morbidities were obtained from patient interviews and rheumatology file reviews. The mean age of our patients was 58.2, with a female preponderance (57.3%). Skin involvement preceded the arthritis or was diagnosed simultaneously in 90.1% of cases. The most common joint involvement was an RA-like arthritis (49.7% of the patients) correlating positively with age, female gender, and disease duration. Dactylitis and nail involvement were observed in 33.6 and 36.2% of the patients, respectively. Radiographic bone erosions were noted in a third of the patients, correlating with DIP and RA-like arthritis patterns. Most patients were treated with methotrexate (73.8%) and a combination therapy (41.4%). An increased incidence of hypertension, hyperlipidemia, and diabetes mellitus was noted in our cohort compared to the general Israeli population. Our survey, the first of its kind conducted in Israel, noted a relative increase in the polyarticular manifestation of PsA and a decrease in spondyloarthropathy, compared to historic series, with more aggressive disease found in women above the age of sixty. These findings are in line with recent surveys.

Background: Extended-spectrum beta-lactamase (ESBL) resistance is a growing concern in and outside hospitals. Physicians often face a true clinical dilemma when initiating empirical antibiotic treatment in patients admitted to internal medicine departments., Objectives: To determine the prevalence of risk factors for ESBL resistance in patients with urinary tract infection (UTI) admitted to internal medicine departments., Methods: We conducted a retrospective analysis of the medical records of patients with UTI admitted to an internal medicine division in a community-based academic hospital over a 1 year period. We collected clinical, laboratory and imaging data that were available to the treating physician at admission. Outcome measures included ESBL resistance and death., Results: Of the 6754 admissions 366 patients were included in the study. Hospitalization during the previous 3 months (odds ratio 3.4, P < 0.0001), residency in a long-term-care facility (OR 2.4, P = 0.004), and the presence of a permanent urinary catheter (OR 2.2, P = 0.015) were correlated to ESBL resistance with statistical significance. These risk factors were extremely prevalent in our patient cohort., Conclusions: ESBL resistance is becoming prevalent outside hospital settings, and patients admitted to an internal medicine department with UTI frequently carry risk factors for harboring resistant bacteria. In such patients a high index of suspicion and early targeted antibiotic treatment for ESBL-producing Enterobacteriaceae may be justified.

Objective: Kikuchi Fujimoto disease (KFD) is a rare, benign disorder, usually characterized by cervical lymphadenopathy. Most available data on KFD has come from the Far East. We examined the characteristics of KFD in Israel., Methods: A retrospective analysis of the records of all patients diagnosed as KFD in seven medical centers in Israel and all the cases previously reported as having occurred in Israel in the literature., Results: Nineteen patients were included, 13 new cases and six from the literature. Mean age of patients was 23 (range 9-50) years. Female/male ratio was 1.1:1. Cervical lymphadenopathy, the hallmark of KFD in the Far East (97%), was less frequent in Israel (44%). However, Israeli patients presented more often with generalized (26%) or retroperitoneal (21%) lymphadenopathy (P < 0.01). Systemic signs such as fever (73%), night sweats (21%), weight loss (21%), hepatomegaly or splenomegaly (25%), and elevated sedimentation rate (52%) were more common in Israeli patients compared to most reports from other parts of the world, excluding Germany (P < 0.05). Leukopenia was evident in most Israeli patients (72%) in contrast to other countries (P < 0.01). Clinical presentation of KFD in Germany was comparable to Israel in most aspects., Conclusion: The clinical presentation of KFD in Israel often resembles a systemic disease with fever, leukopenia and generalized or retroperitoneal lymphadenopathy in more than half of the cases, contrary to the presentation in the Far East, which typically includes cervical lymphadenitis, and less frequently, systemic manifestations., (Copyright 2010 Elsevier Inc.

Background: Parallel to increased life expectancy, the number of very elderly patients hospitalized in internal medicine departments is growing rapidly, although clinical data on hospital care are lacking., Objectives: To investigate the sociodemographic data, hospitalization characteristics and outcomes of nonagenarian patients, as these measures are necessary for evaluating prognostic information and predictors of mortality., Methods: We reviewed the medical records of all patients aged > or = 90 hospitalized in our institute's Department of Internal Medicine. The data comprised 482 admissions of 333 patients hospitalized over a one year period., Results: Half of the study patients were residents of nursing institutions. A high rate of atrial fibrillation was documented (106 patients, 32%). Acute infectious diseases constituted the leading diagnosis (276/482 admissions, 57%), followed by acute coronary syndrome (17% of admissions). In-hospital mortality occurred in 74 patients (22%). Chronic therapy with statins or acetylsalicylic acid was inversely related to mortality (P<0.05). The main predictors for in-hospital death of nonagenarians were pressure sores, older age, atrial fibrillation, malignant disease, and admission due to an acute infection, especially Clostridium difficile-associated diseases in addition, mental decline, permanent urinary catheter, leukocytosis, renal failure and hypoalbuminemia predicted post-discharge mortality. Admission due to an infectious disease but not acute coronary syndrome was significantly correlated to in-hospital and post-discharge mortality (P<0.001)., Conclusions: Hospitalized nonagenarians comprise a growing group with distinct characteristics and increasing significance in the daily practice of internal medicine departments. Comprehensive assessment of the elderly at admission together with identification of the above clinical and laboratory risk factors for mortality will help determine in-hospital management, discharge planning and rehabilitation programs.

The incidence of Pneumocystis Carinii pneumonia (PCP) may rise due to a more extensive use of immunosuppressive therapy. Information and guidelines in the last decade regarding prevention, diagnosis and treatment of the disease were based upon data collected in patients with Acquired Immuno Deficiency Syndrome (AIDS). However, scientific data regarding risk factors, clinical manifestations and treatment of PCP in patients without AIDS is accumulating. The major risk factors for acquiring PCP are hematological malignancies and treatment with immunosuppressive drugs, especially corticosteroids. The clinical course deteriorates more rapidly than in patients with AIDS and many patients have other opportunistic coinfections, especially with Cytomegalovirus and Candida. The duration of treatment may be shorter and drug tolerance is usually better than in patients with AIDS. However, mortality remains high even with appropriate treatment and necessitates a high index of suspicion and the use of empiric treatment even before a definitive diagnosis is made.

Objective: To evaluate the phase plane (PP) ECG as a method for detecting acute coronary occlusion (ACO)., Background: Balloon inflation in a coronary artery during PTCA produces acute myocardial ischemia. The sensitivity of the standard ECG for detecting ACO is approximately 50%, depending on the number of leads recorded., Methods: The standard ECG signals of 18 patients (91 leads), undergoing PTCA were sampled and converted to digital data, prior to, and during acute coronary occlusion. PPs were constructed by projecting the ECG signals and their first derivatives onto a two-dimensional plane. Standard ECG signals and PPs, prior to ACO, were compared to their respective recordings and PPs during ACO., Results: Using the standard ECG analysis, the acute occlusion was detected in 39 of 91 leads (43%), and in 15 of 18 patients (83%), whereas using the PP analysis it was detected in 82 of 91 leads (90%), and in all 18 patients (100%) (P<0.001, for leads). The median number of leads per patient demonstrating standard ECG changes was 2.0, whereas for the PP analysis it was 5.5 (P<0.001). The specificity of the PP method was 83.5%., Conclusions: The sensitivity of the PP method for detecting ACO during PTCA was superior to that of the standard ECG analysis. A smaller lead system is required to detect changes of ACO, during PTCA, when the PP method is used. The PP method is simple, low-priced, and may serve to detect acute myocardial ischemia in a number of clinical settings.

During the recent Persian Gulf war, the civilian population in Israel was frequently instructed to stay in sealed rooms in preparation for a possible chemical missile attack. The war broke out in mid-winter, and in many instances it was necessary to heat the rooms. The use of open fires or malfunctioning heating appliances inside sealed rooms could create ideal conditions for carbon monoxide (CO) poisoning. Six patients with CO intoxication resulting from confinement inside sealed rooms were referred for hyperbaric oxygen (HBO) treatment. Indications for HBO therapy were loss of consciousness and metabolic acidosis. The treatment protocol consisted of 90-min exposure to 100% oxygen at 2.5 atmospheres absolute (ATA), with repeated exposures when required. All patients made a full recovery. The risk of CO poisoning should be taken into consideration and should determine the selection of heating devices for future use in similar circumstances.
