Background: The extent of medical and financial problems of polypharmacy in the elderly is disturbing, particularly in nursing homes and nursing departments.

Objectives: To improve drug therapy and minimize drug intake in nursing departments.

Methods: We introduced a geriatric-palliative approach and methodology to combat the problem of polypharmacy. The study group comprised 119 disabled patients in six geriatric nursing departments, and the control group 71 patients of comparable age, gender and co-morbidities patients in the same wards. After 12 months, we assessed whether any change in medications affected the death rate, referrals to acute care facility and costs.

Results: A total of 332 different drugs were discontinued in 119 patients (average of 2.8 drugs per patient) and was not associated with significant adverse effects. The overall rate of drug discontinuation failure was 18% of all patients and 10% of all drugs. The 1 year mortality rate was 45% in the control group but only 21% in the study group (P < 0.001, chi-square test). The patients’ annual referral rate to acute care facilities was 30% in the control group but only 11.8% in the study group (P < 0.002). The intervention was associated with a substantial decrease in the cost of drugs.

Conclusions: Application of the geriatric-palliative methodology in the disabled elderly enables simultaneous discontinuation of several medications and yields a number of benefits: reduction in mortality rates and referrals to acute care facilities, lower costs, and improved quality of living.

Background: Surgery for spinal stenosis is a frequent procedure in elderly patients. Presentation, hospital course and outcome of disease, including pain perception, may vary among patients of different ethnic origin.

Objectives: To evaluate whether differences in various medical indicators can explain differences in pain perception between two ethnic groups

Methods: We conducted a case-control study on the experience of two spinal units treating a mixed Arab and Jewish population, and compared the data on 85 Arab and 189 Jewish patients undergoing spinal lumbar surgery.

Results: Arab patients were younger (P = 0.027), less educated (P < 0.001), had a higher body mass index (P = 0.004) and included a higher proportion of diabetics (P = 0.013). Preoperative pain intensity (P = 0.023) and functional disability (P = 0.005) were more prominent, and factors associated with pre- or postoperative pain perception differed between the two ethnic groups. Despite these differences, results on follow-up were similar with respect to pain perception and level of disability.

Conclusions: A better understanding of ethnic differences is crucial for predicting surgery outcomes.

Background: Studies have found ethno-cultural disparities in health care delivery in different countries. Minority populations may receive lower standards of care.

Objectives: To test a hypothesis that Jewish Ethiopian women may be receiving less preventive recommendations than other women in Israel.

Methods: A telephone survey was conducted using a structured questionnaire designed specifically for this study in Hebrew, Russian and Amharic (Semitic language of Ethiopia). The study group included 51 post-menopausal women of Ethiopian origin, aged 50–75. The control group included 226 non-Ethiopians matched by age, some of whom were immigrants from the former Soviet Union. The questionnaire dealt with osteoporosis and breast cancer screening and prevention.

Results: All the parameters measured showed that the general population received more preventive treatment than did Jewish Ethiopian women, including manual breast examination, mammography, osteoporosis prevention, bone density scans, and recommendations for a calcium-rich diet, calcium supplementation, hormone replacement therapy, biphosphonates and raloxifen. On a logistic regression model the level of knowledge of the Hebrew language, age, ethnicity and not visiting the gynecologist were significantly related to not having received any preventive medicine recommendations.
Conclusions: Differences in cultural backgrounds and language between physicians and their patients may become barriers in the performance of screening and preventive medicine. Recognizing this potential for inequity and using methods to overcome these barriers may prevent it in the future

Background: Patients with severe persistent asthma despite GINA 2002 step 4 treatment are at risk for asthma-related morbidity and mortality. This study constitutes the Israeli arm of the international INNOVATE study.

Objectives: To determine the efficacy and safety of Xolair® as an add-on treatment in patients with severe persistent asthma.

Methods: Asthma patients (age 12–75 years) not controlled with high dose inhaled corticosteroids and long-active beta-2 agonists were randomized to receive either Xolair® or placebo for 28 weeks in a double-blind study in two Israeli centers.

Results: Thirty-three patients, 20 females and 13 males, mean age 54 ± 11.7 years, were included in the Israeli arm of the INNOVATE study. There were neither major adverse events nor withdrawals from the study. Xolair® (omalizumab) significantly reduced the rate of clinically significant asthma exacerbations (55% reduction) and all asthma-related emergency visits (53% reduction).
Conclusions: In patients with severe persistent difficult-to-treat asthma, despite regular treatment with LABA[1] and inhaled corticosteroids (GINA 2002 step 4), Xolair® is a safe and effective treatment

Background: Asthma control and treatment compliance are widely investigated issues around the world. Studies have demonstrated relatively low asthma compliance and control in 40–90% of asthma patients in different countries. There are no available data on the Israeli adult asthmatic population

Objectives: To investigate the level of asthma control and compliance in adult asthmatic patients.

Methods: This cross-sectional study of consecutive adult asthmatic patients visiting the pulmonary clinic used a combined questionnaire that included demographics, data on asthma severity and management, and asthma control and compliance scores. Each patient was interviewed and questionnaires were filled out during a routine visit.

Results: The study group comprised 142 males (35.4%) and 259 females (64.6%). Compliance was found optimal in 8 patients (2%), fair in 146 (36%), partial in 156 (39%) and poor in 92 (23%) of the participating asthmatic patients. Asthma control was found optimal in 26 (7%), fair in 124 (31%), partial in 122 (30%) and poor in 129 (32%) patients. Sephardic and Ashkenazi Jewish origin, higher level of education, and treatment protocol including either single fixed-dose inhalers or short-acting beta-agonist bronchodilators significantly improved compliance in our cohort. Socioeconomic status and compliance were found to positively affect asthma control, whereas active smoking negatively affected asthma control in the study patients.

Conclusions: The figures of optimal asthma control and compliance to treatment in Israeli adult asthmatics are low and worse than reported in other studies abroad.

Background: Infective endocarditis is a common disease with significant morbidity and mortality.

Objectives: To define clinical and echocardiographic parameters predicting morbidity and in-hospital mortality in patients with infective endocarditis hospitalized in a tertiary hospital from 1991 to 2000.

Methods: All patients with definite IE diagnosed according to the Duke criteria were included. We examined relevant clinical features that might influence outcome.

Results: The study group comprised 100 consecutive patients, 77 with native valve and 23 with prosthetic valve endocarditis. The overall in-hospital mortality rate was 8%. There was a higher mortality in the PVE[1] group compared to the NVE[2] group (13% vs. 7%, P = 0.07). The mortality rate in each group, with or without surgery, was not significantly different. Clinical predictors of mortality were older age and hospital-acquired endocarditis. The presence of vegetations and their size were significant predictors of major embolic events and mortality. Staphylococcus aureus was a predictor of mortality (25% vs. 5%, P < 0.005) and abscess formation. Multivariate logistic analysis identified vegetation size and S. aureus as independent predictors of mortality.

Conclusions: Mortality is higher in older hospitalized patients. S. aureus is associated with a poor outcome. Vegetation size is an independent predictor of embolic events and of a higher mortality.

Background: Oral lichen planus is a cell-mediated immune condition of unknown etiology. A possible association of OLP[1] with hepatitis C virus infection has been documented in specific populations. However, no such possible association has been studied in Israel.

Objectives: To assess the prevalence of HCV[2] antibodies among patients with OLP in Israel.

Methods: The prevalence of HCV seropositivity was studied in OLP patients (n=62) and compared with that of a control group (n=65) and with the prevalence among healthy volunteer blood donors (n=225,452) as representatives of the general population.

Results: The prevalence of HCV, as detected by the presence of anti-HCV antibodies screened by enzyme-linked immunosorbent assay, and confirmed by recombinant immunoblot assay, was 4.8%, 1.5% and 0.1%, respectively. HCV seropositivity in the OLP patients was significantly higher than in the healthy blood donors (P < 0.001).

Conclusions: A possible association between OLP and HCV is suggested. Therefore, screening OLP patients for antibodies to HCV is recommended.

Background: Despite improved management of heart failure patients, their prognosis remains poor.

Objectives: To characterize hospitalized HF[1] patients and to identify factors that may affect their short and long-term outcome in a national prospective survey.

Methods: We recorded stages B-D according to the American College of Cardiology/American Heart Association definition of HF patients hospitalized in internal medicine and cardiology departments in all 25 public hospitals in Israel.

Results: During March-April 2003, 4102 consecutive patients were recorded. Their mean age was 73 ± 12 years and 57% were males; 75.3% were hypertensive, 50% diabetic and 59% dyslipidemic; 82% had coronary artery disease, 33% atrial fibrillation, 41% renal failure (creatinine ³ 1.5 mg/dl), and 49% anemia (hemoglobin £ 12 g/dl). Mortality rates were 4.7% in-hospital, 7.6% at 30 days, 18.7% at 6 months and 28.1% at 12 months. Multiple logistic regression analysis revealed that increased 1 year mortality rate was associated with New York Heart Association III–IV (odds ratio 2.07, 95% confidence interval 1.78–2.41), age (for 10 year increment) (OR[2] 1.41, 95% CI[3] 1.31–1.52), renal failure (1.79, 1.53–2.09), anemia (1.50, 1.29–1.75), stroke (1.50, 1.21–1.85), chronic obstructive pulmonary disease (1.25, 1.04–1.50) and atrial fibrillation (1.20, 1.02–1.40).

Conclusions: This nationwide heart failure survey indicates a high risk of long-term mortality and the urgent need for the development of more effective management strategies for patients with heart failure discharged from hospitals.

Background: Heart failure with preserved systolic left ventricular function is a major cause of cardiac disability.

Objectives: To examine the prevalence, characteristics and late clinical outcome of patients hospitalized with HF-PSF[1] on a nationwide basis in Israel.

Methods: The Israel nationwide HF survey examined prospectively 4102 consecutive HF patients admitted to 93 internal medicine and 24 cardiology departments in all 25 public hospitals in the country. Echocardiographic LV function measurements were available in 2845 patients (69%). The present report relates to the 1364 patients who had HF-PSF (LV ejection fraction ≥ 40%).

Results: Mortality of HF-PSF patients was high (in-hospital 3.5%, 6 months 14.2%, 12 months 22.0%), but lower than in patients with reduced systolic function (all P < 0.01). Mortality was higher in patients with HF as the primary hospitalization diagnosis (16.0% vs. 12.5% at 6 months, P = 0.07 and 26.2% vs. 18.0% at 12 months, P = 0.0002). Patients with HF-PSF who died were older (78 ± 10 vs. 71 ± 12 years, P < 0.001), more often female (P = 0.05) and had atrial fibrillation more frequently (44% vs. 33%, P < 0.01). There was also a relationship between mortality and pharmacotherapy: after adjustment for age and co-morbid conditions, mortality was lower in patients treated with angiotensin-converting enzyme inhibitors (P = 0.0003) and angiotensin receptor blockers (P = 0.002) and higher in those receiving digoxin (P = 0.003) and diuretic therapy (P = 0.009).

Conclusions: This nationwide survey highlights the very high late mortality rates in patients hospitalized for HF without a decrease in systolic function. The findings mandate a focus on better evidence-based treatment strategies to improve outcome in HF-PSF patients.

Background: Coronary heart disease and ischemic stroke are among the leading causes of morbidity and mortality in adults, and cerebrovascular disease is associated with the presence of symptomatic and asymptomatic CHD[1]. Several studies noted an association between coronary calcification and thoracic aorta calcification by several imaging techniques, but this association has not yet been examined in stable angina pectoris patients with the use of spiral computed tomography.

Objectives: To examine by spiral CT the association between the presence and severity of CC[2] and thoracic aorta calcification in patients with stable angina pectoris.

Methods: The patients were enrolled in ACTION (A Coronary Disease Trial Investigating Outcome with Nifedipine GITS) in Israel. The 432 patients (371 men and 61 women aged 40–89 years) underwent chest CT and were evaluated for CC and aortic calcification.

Results: CC was documented in 90% of the patients (n=392) and aortic calcification in 70% (n=303). A significant association (P < 0.05) was found between severity of CC and severity of aortic calcification (as measured by area, volume and slices of calcification). We also found an association between the number of coronary vessels calcified and the presence of aortic calcification: 90% of patients with triple-vessel disease (n=157) were also positive for aortic calcification (P < 0.05). Age also had an effect: 87% of patients ≥ 65 years (n=219) were positive for both coronary and aortic calcification (P = 0.005) while only 57% ≤ 65 (n=209) were positive for both (P = 0.081).

Conclusions: Our study demonstrates a strong association between the presence and severity of CC and the presence and severity of calcification of thoracic aorta in patients with stable angina pectoris as detected by spiral CT.
