[Cellular phone interference with medical instruments].

Cellular telephones and other telecommunication equipment occasionally cause malfunctioning of medical equipment, including life-support equipment. We review such malfunctioning and relate it to Israeli and Worldwide standards, analyzing the characteristics of the interference in terms of amplitude and frequency. The results of a controlled study of interference by cellular telephones and portable 2-way radios with medical devices in our clinical departments are also presented. The levels of background environmental electromagnetic noise at several sites in both Hadassah hospitals (Ein Karem and Mount Scopus) were measured, as well as signal levels of cellular telephones and other communication equipment at various distances and in various areas. We recommend 2 different levels of restrictions on the use of this equipment within the hospital. These include prohibition of the use of wireless telecommunication equipment in intensive care areas and operating theaters. In all other areas it is recommended to turn off the cellular telephone within 1 meter of medical devices and not to transmit (but only to receive) calls with a portable 2-way radio within a 5 meter distance of medical devices.

Emergency preparedness and response in Israel during the Gulf War.

We examined the effect of the emergency response on medical and public health problems during the 1991 Gulf War in Israel. On the first day of the conflict, the number of deaths from suffocation, asphyxiation, aspiration, myocardial infarction, cardiac arrest, and cerebrovascular accident increased abruptly, as did the number of sudden deaths associated with the use of tight-fitting masks with filters in sealed rooms. Much of the excess risk for death from cardiorespiratory complications during the first alert may have been a consequence of its duration (140 minutes). Mass evacuation and concrete buildings are believed to have kept the death toll from trauma down, and mask use may have protected against facial and upper-airway injuries. Falls and hip fractures, airway irritation from exposure to bleach, carbon monoxide intoxication from open kerosene heaters in sealed rooms, and self-injection with atropine syringes were also noted. A measles epidemic and increased death rates from automobile crashes were other preventable causes of death. Protection against biological warfare was limited to surveillance of trends for pneumonia and gastroenteritis. Emergency planners failed to anticipate the need for better mask fit, hands-on training in the use of masks, and special guidelines for older persons to prevent deaths from suffocation and other cardiovascular-respiratory problems in the first minutes of use. If masks are to be distributed as a protection against chemical warfare, a simpler model including the use of shrouds for whole-body skin protection might help avoid cardiorespiratory complications. Public health problems not adequately dealt with in the predisaster period are apt to emerge with greater severity during a crisis.

Israeli women were at a higher risk than men for mortality following coronary bypass surgery.

As part of a national study of surgical departments is Israel, cardiac surgery patients undergoing open heart surgery between 1987 and 1989 were followed-up prospectively. Of these, 1,046 patients had coronary artery bypass grafting (CABG) and are the subject of this report. The six-months mortality after surgery was 12.9% among 202 women and 4.1% among 844 men. Female gender was an independent predictor of mortality even after controlling for the effect of 14 putative risk factors. The adjusted relative risk for mortality in women compared to men was 2.79 (1.5-5.2). In an attempt to understand this excessive mortality among women, a detailed analysis in one of the participating hospitals revealed differences associated with surgical technique by gender, such as proportion of patients with entirely venous grafting vs internal mammary artery grafts (IMA). Thirty percent of women vs 4.8% of men had entirely venous grafting. Adjusting the data for differences in the proportion of venous grafting has obliterated the difference in mortality between the genders in that hospital. We suggest that interventions to reduce mortality among women should involve a more careful choice of female candidates for CABG surgery, as well as introduction of modifications in the operating technique.

An international practitioner data bank as a quality tool.

While international tort costs have not reached the level of those in the United States, international medical employers, like their American counterparts, must be able to ascertain updated objective information regarding the physicians they are going to employ, in order to protect their patients and organizations from the increasing risks in today's medical environment. The NPDB set up in the United States by the United States Congress provides a structure that can record and set standards for professional reviews. While the data bank established in the United States can still be considered a new entity, and the exact impact it has on quality, peer review and risk management is still being judged, it is the first step towards an organized, objective governing body. We recommend that an international committee convene to study the American model of a data bank and decide how and which parameters could be used for setting international standards and norms to be recorded in an international data bank. This data bank would be an important addition to the increasing array of tools available to ensure quality care.

Quantity in health care is not always a substitute for quality.

Examines the outcomes of attempts to improve health services in the former Communist countries of Eastern Europe and in the West European democracies. Discovers that while the East Europeans focused their efforts on increasing the numbers of doctors and beds per patient, while keeping to relatively low levels of investment in technological advances, West European countries have taken the opposite approach, emphasizing quality of care, particularly advanced care, reducing the numbers of physicians and hospital beds, acquiring advanced technological systems for diagnosis and treatment and spending ten times as much per patient as in Eastern Europe. Concludes that the West European approach has led to far better results.

Decreased hospital utilization by older adults attributable to a home hospitalization program.

OBJECTIVE: To evaluate the cost effectiveness of a short-term home health care program for older people, Home Hospitalization (HH), compared with the alternative of regular ambulatory care with general or geriatric hospitalization as necessary. SETTING: Our HH was initiated in November 1991 to serve Jerusalem residents. Program staff included physicians, nurses, and paramedical professionals. Other medical/hospital services were provided nonselectively by the general medical personnel of the various hospitals in Jerusalem. STUDY DESIGN: Patients over the age of 65 were either referred to the HH program (study group, n = 36,500) or to routine medical care (control group; n = 9000) depending on their Sick Fund assignment. Hospital utilization rates per enrollee were studied prospectively and compared both between the two groups and with hospitalization rates in the year before the initiation of the program. RESULTS: During the first 26 months of operations, the HH program cared for 741 older persons for a total of 37,290 days' care at an average daily costs of $30.06 (1992) and $23.64 (1993). Annual general hospitalization rates per person declined in the study group from 2.80 days in the 1991 baseline period to 2.65 days in 1992 and to 2.54 days in 1993. Hospitalization rates in the control group increased from 2.62 in 1991 to 2.70 days/member and 2.71 days/member in 1992 and 1993, respectively. Annual geriatric hospitalization rates declined considerably in the study group from the 1991 baseline of 1.49 to 1.34 (1992) to 1.33 (1993). The control group experienced a small decrease from 1.64 (1991) to 1.58 (1992) and then a rise to 1.68 days per member in 1993. For the 26-month duration of the program, estimated savings of 20,773 general hospital days ($5.54 million) and 8486 geriatric hospital days ($0.98 million) exceeded its costs ($0.97 million), providing a cost/benefit ratio of 5.7/1. In addition, patient satisfaction was high. CONCLUSION: The HH program provided a cost effective substitute for care in a geriatric or general hospital for Jerusalem's elderly.

Osteoarthritis, the hazard of living longer: arthroscopy vs. conservative treatment.

The lengthening of the average life span has led to an increase in degenerative diseases, among them osteoarthritis. Arthroscopy, which has been used extensively to decrease pain and inflammation and increase the range of motion, has recently been challenged as the treatment of choice. Several studies have found that joint lavage, which is a less costly procedure, provides better solutions to joint disorders. In Israel, where resources for health care are limited, physicians must also be guided by cost-benefit and cost-effectiveness. Since there is limited benefit to be gained from arthroscopy in cases where there is no mechanical damage to the knee, we suggest that nonsurgical, conservative methods be employed in treating the majority of cases of osteoarthritis.

Insulin-like growth factor I and its binding proteins 3 and 4 are increased in Human inflammatory synovial fluid.

OBJECTIVE: To measure insulin-like growth factor I (IGF-I) and its binding proteins (IGFBP) in human synovial fluid (SF), as IGF-I resistance in the chondrocyte was implicated in the pathogenesis of inflammatory arthritis. METHODS: Ten patients with inflammatory arthritis and 7 controls were evaluated. IGF-I and IGFBP-3 were measured by radioimmunoassay while all IGFBP were evaluated by Western ligand blotting. RESULTS: Serum IGF-I did not differ between patients and controls (22.3 +/- 2.9 vs 22.0 +/- 3.0 nmol/l), while significantly higher values were found in inflammatory SF compared with noninflammatory SF (14.7 +/- 1.5 vs 10.2 +/- 1.2 nmol/l; p = 0.05). IGFBP-3 and IGFBP-4 were the most prominent bands found in inflammatory SF by Western ligand blotting. The 24 kDa IGFBP-4 band appeared faintly in 2 noninflammatory effusions and was nearly absent in others. IGFBP-3 levels in sera from the 2 groups did not differ (2.9 +/- 0.3 vs 2.5 +/- 0.3 mg/l), but were significantly higher in inflammatory compared with noninflammatory effusions (1.5 +/- 0.2 vs 0.9 +/- 0.2 mg/l; p = 0.05). CONCLUSION: The pattern of IGFBP in SF differs in inflammatory versus noninflammatory joints.

Factors predicting emergency room utilization in a 70-year-old population.

Emergency room (ER) utilization in a representative sample (n = 605) of 70-year-old Jerusalem residents was investigated using multiple and logistic regression techniques. Around 23% of the study population visited an ER during the pre-interview year. Problems associated with ER use were heart diseases (mainly ischemic), asthma, renal disorders, psychiatric problems, headaches, and nocturia. Also associated with increased ER use were prior hospital admissions, taking sleeping pills, driving a car, distance from one's general practitioner, and low self-assessed health status. The availability of help from children increased ER use, possibly by sharing in the decision-making process or by helping with post-visit financial bureaucracy. Persons with cognitive problems had decreased ER use, possibly due to their inability to cope with the related complex decision-making process. The inclusion of interaction terms improved the models fit, in keeping with the general philosophy of geriatric care which often deals with cases presenting multiple diagnoses in addition to various social problems. Information on key variables identified as predictors of ER use in order to predict ER use as a basis for budget allocation to specific sick funds, was collected by means of a postal questionnaire or by phone.

Discharge from hospital and its effect on surgical wound infections. The Israeli Study of Surgical Infections (ISSI).

A multicenter study of 2846 consecutive hernia operations was conducted to identify risk factors for infections that occurred during the hospitalization and post-discharge from hospital. Operated patients were followed-up for 30 days after surgery, whether at home or still hospitalized, and half the wound infection episodes were found to occur at home. Risk factors for both in-hospital and post-discharge infections seemed to be influenced by; (a) the selective nature of discharge, (b) the differential effect some risk factors had on either early or late infections. On any given day, patients selected by the clinical team to remain in hospital were more "at risk" for infection than those who left. As a result, they had a better chance of being diagnosed as infected during hospitalization. By contrast, those who were discharged home were perceived as low risk for complications. Subsequent infections in these patients occurred either due to factors "causing" late infections, therefore, unappreciated at the time of discharge, or unknown risk factors. More study risk factors were associated with in-hospital than with post-discharge infections, especially those associated with "early" infections. The implications of these findings for future evaluations of medical care in hospitalized patients are discussed.

Differential effect of risk factors on early and late wound infections in patients undergoing herniorrhaphies.

In a prospective follow-up of 2846 patients who underwent hernia repair in 22 general surgery departments in Israel, factors affecting early or late infections were explored. Risk factors included inherent patient characteristics such as old age, ethnic group, and type of hernia prior to the surgery. Patient management factors included duration of the operation, use of urinary catheters, and use of drains. Of the 12 variables studied, only three had a constant effect during the entire 30-day follow-up. The other factors affected the occurrence of either early or late infections, but not both. For example, patients undergoing long operations, or from ethnic minorities, had a high rate of early infection, while those with special wound treatment (such as evacuation of hematomas) had high rates of late infection. It is postulated that factors present at the time of the operative incision tend to "cause" early infections, while factors that accumulate over time, or develop after leaving the operating theater, tend to affect late infections.
