Telemedicine is the application of advanced telecommunication technology for diagnostic, monitoring and therapeutic purposes. It enables data transmission from the patient's whereabouts or his/her primary care provider to a specialized medical call center. Telecardiology is a highly developed medical discipline involving almost every aspect of cardiology, including acute coronary syndromes, arrhythmias, congestive heart failure, sudden cardiac arrest and others. Israel is one of the leading countries in the use of telecardiology, achieving both extended survival, improvement of the patient's quality of life, and significant reduction in health costs. 

Background: Obstructive sleep apnea syndrome (OSAS) is a sleep-related breathing disorder characterized by excessive daytime sleepiness, accidents and high medical expenses. The first line of treatment for OSAS is continuous positive airway pressure (CPAP).

Objectives: To examine attitudes and beliefs as well as physiological and sociodemographic factors affecting OSA patients' decision whether or not to purchase a CPAP device.

Methods: The study was divided into two stages; in the first, 83 subjects completed self-administered questionnaires prior to sleep examination (polysomnographic study). The questionnaires related to sleep habits, sleep disorders, questions organized around health belief model (HBM) concepts, sociodemographic information, health status and PSG[1] examination. In the second stage, 3 months later, 50 OSAS patients were interviewed by telephone, which included questions about their reasons for purchasing/not purchasing the CPAP device.

Results: Only 48% of the OSAS patients purchased the CPAP device. The significant factors positively affecting the decision included higher levels of physiological factors such as body mass index (coefficient 0.36, P < 0.05) and respiratory disturbance index (coefficient 0.16, P < 0.05), higher income levels (coefficient 3.26, p < 0.05), and higher levels of knowledge about OSAS (coefficient -2.98, P < 0.1).

Conclusions: Individuals who are more aware of their own health condition, are better informed about OSAS and have higher incomes are more likely to purchase the device. We suggest reducing the level of co-payment and providing patients with more information about the severe effects of OSAS.

Background: Influenza vaccination of community-dwelling elderly is widely recommended. Observational studies have shown a strong association between physicians' personal vaccination status and their reported level of recommendation to patients and possibly their patients' actual vaccination. No published trials have examined whether increasing vaccination rates of primary care staff raises vaccination among their patients. Proof of a positive effect would support the notion that vaccinating health care workers benefits their patients.

Objectives: To examine whether an intervention to increase staff vaccination also increases vaccination of their patients aged 65 and over.

Methods: A trial examining an intervention aiming to raise staff immunization rates was performed in primary care community clinics in the Jerusalem area. The study population comprised the staff of 13 randomly chosen intervention clinics during the season of 2007–2008, with another 14 clinics serving as controls. The intervention resulted in a staff vaccination rate of 52.8% compared to 26.5% in the control clinics (66.1% and 32.2% among physicians). No intervention was directed at the patients. Data on patient vaccination and other patient characteristics were extracted from the health funds’ computerized databases.

Results: The percentage of patients vaccinated during the intervention season was 57.8% in both intervention and control groups, reflecting an increase of 14.4% compared to the previous season in the intervention clinics and of 13.4% in the control clinics. Logistic regression demonstrated a statistically significant association between intervention and patient vaccination with an odds ratio of 1.10 (95% confidence interval 1.03–1.18). However, analysis adjusting for clustering did not show a significant association.

Conclusions: Increasing influenza vaccination of the medical staff did not substantially increase patient vaccination. These results do not show any patient benefit from staff vaccination in primary care.
 

Before World War II the number of Jewish physicians practicing pediatric medicine in Germany was very high, but soon after the National Socialists came to power the discrimination against Jewish physicians began. One of them, Dr. Albert Uffenheimer, serves as a moving example of this persecution. Dr. Uffenheimer was engaged in the fight against the high infant mortality and was instrumental in the creation of public health facilities for counselling parents. In 1925 he became Director of the Children’s Hospital in Magdeburg and within a short time had improved the medical care of both infants and mothers. In April 1933, two months after the Nazi takeover, he was dismissed from his post at the Children’s Hospital in Magdeburg and immigrated to the United States. Dr. Uffenheimer was a pioneer in the field of public health before such new concepts were recognized as important. As such he should be remembered as a founding father of social pediatrics in Germany.

Background: Rapid reperfusion of an infarct-related artery is crucial for the successful treatment of ST elevation myocardial infarction. Every effort should be made to shorten door-to-balloon time.

Objectives: To investigate whether bypassing the emergency room (ER) has a positive influence on door-to-balloon time in patients presenting with ST elevation myocardial infarction (STEMI) and whether the reduction in door-to-balloon time improves patients’ clinical outcome.

Methods: We analyzed data of 776 patients with STEMI[1] from the 2004 and the 2006 Acute Coronary Syndrome Israeli Survey (ACSIS) registry. The ACSIS[2] is a biennial survey on acute myocardial infarction performed in all 25 intensive cardiac care units in Israel during a 2-month period. Twenty-five percent of patients (193 of 776) arrived directly to the intensive cardiac care unit (ICCU) and 75% (583 of 776) were assessed first in the ER[3]. We compared door-to-balloon time, ejection fraction, 30 days MACE (major adverse cardiac and cerebrovascular events) and 30 days mortality in the two study groups.

Results: There was significantly shorter door-to-balloon time in the direct ICCU group as compared with the ER group (45 vs. 79 minutes, P < 0.002). Patients in the direct ICCU group were more likely to have door-to-balloon time of less than 90 minutes in accordance with ACC/AHA guidelines (88.7% vs. 59.2%, P < 0.0001). Moreover, patients in the direct ICCU group were less likely to have left ventricular ejection fraction < 30% (5.4% vs. 12.2%, P = 0.045) and less likely to have symptoms of overt congestive heart failure. Lastly, 30 days MACE[4] was significantly lower in the direct ICCU group (22 vs. 30%, P < 0.004).

Conclusions: There is significant reduction of the door-to-balloon time in the direct ICCU admission strategy. This reduction translates into improvement in clinical outcome of patients. It is reasonable to apply the direct ICCU strategy to patients with STEMI.

Background: The European Quality of Life 5-Dimensions questionnaire is one of the most commonly used measures of health-related quality of life.

Objectives: To present the feasibility, reliability, and validity of the Hebrew version of the EQ-5D[1].

Methods: We conducted face-to-face interviews with a representative sample (n=1666) of the Israeli Jewish population. The data collected included demographic and medical information, and self-valuation of health using the EQ-5D descriptive system, Visual Analogue Scale and Time Trade-Off. Construct validity was assessed by assuming that older individuals, those with a greater burden of diseases, and those reporting experience with their own severe illness would have lower EQ-5D indexes, VAS[2] and TTO[3] values. Test-retest reliability was assessed in a small sample (n=50) that was reevaluated after a 3 week interval.

Results: Test-retest reliability of the EQ-5D and VAS was very high (r ≥ 0.85). Reliability of the TTO was moderate (r = 0.48). There were significant differences in the EQ-5D index, profiles, VAS and TTO between healthy and sick respondents and younger and older respondents, indicating good validity of the instrument.

Conclusions: The Hebrew translation of the EQ-5D is a practical, reliable and valid instrument for assessing the health-related quality of life of the general Israeli Jewish population.

Background: For health professionals who interact professionally with children, adequate awareness and training regarding the clinical indicators of child abuse and neglect, as well as subsequent reporting and procedures, are essential.

Objectives: To study Israeli health professionals’ experiences with identification and reporting of suspected cases of child abuse and neglect, and their perceived training needs in this area.

Methods: The study group was a convenience sample comprising 95 Israeli health professionals (physicians, nurses, social workers, psychologists, etc.) attending workshops on medical aspects at a national conference on child abuse and neglect. The study was a cross-sectional survey. The health professionals were asked to complete an anonymous structured questionnaire on their experience with child abuse and neglect and on their training needs.

Results: The participants in the survey had relatively high levels of involvement with child protection. Nevertheless, they strongly expressed their need for training, especially in mastering practice skills. The need for training was greater for professionals with less experience in child protection, and there were different needs according to profession.

Conclusions: Despite their prior extensive experience in dealing with child abuse and neglect, most of the health professionals participating in the conference reported the need for training in various areas.

Background: Health care workers bear the risk of both contracting influenza from patients and transmitting it to them. Although influenza vaccine is the most effective and safest public health measure against influenza and its complications, and despite recommendations that HCWs[1] should be vaccinated, influenza vaccination coverage among them remains low.

Objectives: To characterize influenza vaccination coverage and its determinants among employees in an Arab hospital in Israel.

Methods: An anonymous, self-administered questionnaire was distributed among employees involved in patient care in the winter of 2004–2005 at Nazareth Hospital in Israel. The questionnaire included items related to health demographic characteristics, health behaviors and attitudes, knowledge and attitude concerning influenza vaccination, and whether the respondent had received the influenza vaccine during the previous winter or any other winter.

Results: The overall rate of questionnaire return was 66%; 256 employees participated in the study. The immunization coverage rate was 16.4%, similar to that reported for other hospitals in Israel. Logistic regression analysis demonstrated a significant association only between influenza vaccination coverage and the presence of chronic illness and influenza vaccination in the past.

Conclusions: Influenza vaccination coverage among Nazareth Hospital health care workers was low. They did not view themselves as different to the general population with regard to vaccination. An intervention program was launched after the study period, aimed at increasing the knowledge on the efficacy and safety of the vaccine, stressing the importance of vaccinating HCWs, and administering the vaccine at the workplace. The program raised the vaccination coverage to 50%.

Immunization coverage is a major health indicator. In Israel, routine childhood immunizations are provided at community public well-baby clinics. Immunization monitoring is an important cornerstone of a national health policy however, data obtained through sampling carries the risk of under-representation of certain population strata, particularly high risk groups. Despite high national average immunization coverage, specific sub-populations are under-immunized, as highlighted by outbreaks of vaccine-preventable diseases. The mean national immunization coverage at age 2 years (2006 data) was: DTaP[1]-IPV[2]-Hib4[3] (all 93%), HBV[4]3 (96%), MMR1[5] (94%), HAV1[6] (90%). These reports are based on a 17% population-based sample in some districts and on cumulative reports in others. A national immunization registry requires data completeness, protection of confidentiality, compulsory reporting by providers, and links to other computerized health records. It should provide individual immunization data from infancy to adulthood and be accessible to both providers and consumers. In 2008 the Israel Ministry of Health launched a national immunization registry based on immunization reporting from well-baby clinics using a web-based computerized system. As of January 2010, 120 well-baby clinics are connected to the nascent registry, which includes the records of some 50,000 children. The implementation of a comprehensive national immunization registry augurs well for the prospect of evidence-based assessment of the health status of children in Israel.

Background: Down syndrome is one of the most common chromosomal abnormalities. Children and adults with DS[1] have significant medical problems and require life-long medical follow-up.

Objectives: To determine the adequacy of medical surveillance of individuals with DS as recommended by the American Academy of Pediatrics.

Methods: The study was conducted at a multidisciplinary center specializing in the care of DS during the period 2004–2006. At their first visit to the Center, caregivers of individuals with DS were questioned about the medical status of their child including previous evaluations. Medical records brought in by the parents were reviewed.

Results: The caregivers of 150 individuals with DS (age ranging from newborn to 48 years old, median age 5 years) were interviewed and medical records were reviewed. The prevalence of specific medical problems differed between our population and the reported prevalence from other surveys. For example, 39.3% of our population had documented auditory deficits while the reported prevalence is 75%. For gastrointestinal and thyroid disease, the prevalence was higher in the studied population than that reported in the literature. In terms of compliance with the AAP[2] recommendations, most children (94%) underwent echocardiography, but only 42.7% and 63.3% had been tested for auditory or visual acuity respectively. Only 36.3% over the age of 3 years had cervical spine films.
Discussion: Many individuals with DS are not receiving appropriate medical follow-up and the implications of inadequate surveillance can be serious

Background: Respiratory syncytial virus bronchiolitis is the single leading cause of pediatric admissions for infants in the first year of life, presenting regularly in epidemic proportions in the winter months and impacting in a major way on pediatric inpatient services.

Objective: To quantitate the burden of RSV[1] disease on a pediatric service with the purpose of providing a database for proper health planning and resource allocation.

Methods: We conducted a prospective 5 year study of documented RSV infections in a single pediatric service. RSV disease was confirmed by direct immunofluorescence testing of nasal swabs from all hospitalized cases of bronchiolitis.

Results: On average, 147 ± 17 cases of RSV bronchiolitis were admitted annually in the November–March RSV season, representing 7%–9% of admissions and 10%–14% of hospital days. There was a consistent male preponderance of admissions (55–64%) and 15–23% of admissions were patients less than 1 month old. In peak months RSV cases accounted for as many of 40% of the hospitalized infants and was the leading cause of over-occupancy (up to 126%) in the pediatric ward during the winter,

Conclusions: RSV infection is a major burden for pediatric inpatient services during the winter season. This recurrent and predictable “epidemic,” which regularly leads to over-occupancy, requires increased manpower (nursing) and resources (beds, pulse oximeters) to facilitate proper care. Since this annual event is not a surprise nor an unexpected peak, but rather a cyclical predictable epidemiological phenomenon, proper planning and allocation of services are crucial.
