Background: The chronic progressive course of peripheral arterial occlusive disease with its limb-threatening and life-threatening potential is associated with physical, psychological and social distress for elderly patients and their families.

Objective: To evaluate the influence of infra-inguinal bypass surgery for limb salvage, and social support, on quality of life in elderly patients (over 60 years old).

Methods: Sixty patients aged 60 years and above diagnosed with limb-threatening ischemia were evaluated using the SF-36 generic questionnaire for quality of life, and the MOS-SS questionnaire for social support. Thirty patients (group I) were evaluated in the hospital prior to reconstructive surgery and 30 postoperative patients (group II) were evaluated at home at least 6 months after infra-inguinal bypass operations. Both groups were comparable in terms of age, gender, prevalence of ischemic heart disease, diabetes, and other atherosclerosis risk factors.

Results: All quality of life parameters were higher among patients who underwent limb salvage surgery (group II) as compared to preoperative patients (group I), yet the obtained values were lower than those in the general population. Patients in the surgical intervention group had higher levels of function, lower pain levels, and higher emotional and social well-being and, in addition, were spared limb amputation. The findings also indicate that the social support dimensions (emotional support, receipt of information, affection and positive social interaction), as measured in terms of perceived availability, do not operate as one entity. Different types of social support were more beneficial along different stages of the disease.

Conclusion: Peripheral arterial occlusive disease causes severe impairment of the quality of life in elderly patients. Arterial reconstructive surgery improves the quality of life though it still remains low compared to the general population. Social support is beneficial in the treatment of these patients, and the social worker in the vascular surgery department has a key role in identifying the various needs of the patients along the path of their chronic illness.
 

Background: An important question on the health agenda concerns the most appropriate place to hospitalize stroke patients and its effect on acute stroke care.

Objectives: To examine how the existing hospital system treats these patients, specifically: a) the departments to which stroke patients are admitted; b) differences in the admission, diagnosis and rehabilitative care of stroke patients, by department; c) patient characteristics, by department; and d) mortality rates during hospitalization.

Methods: We surveyed 616 people with acute stroke (ICD-CM9 430-433, 436) admitted consecutively to one of seven large general hospitals in Israel between October 1998 and January 1999. Data were collected from medical records at admission and at discharge.

Results: Forty-two percent of the patients were admitted to an internal medicine department, 56% to a neurology department, and only 2% to a geriatric department. The majority (95%) underwent a computed tomography scan of the brain, but other imaging tests were performed on fewer patients, with significant differences among hospitals and between internal medicine and neurology departments. Patients admitted to neurology departments were younger and had milder stroke symptoms than did patients admitted to internal medicine departments. Fifty-three percent of patients received at least one type of rehabilitative care during their hospital stay – usually physiotherapy, and least often occupational therapy. Seventeen percent of stroke patients died during hospitalization. Mortality was not found to be related to the admitting department.

Conclusions: Uniform realistic policies and work procedures should be formulated for all hospitals in Israel regarding the admitting department and processes as well as the performance of diagnostic imaging. Standards of medical and rehabilitative care and discharge destination should be developed to promote quality of care while containing utilization and costs.
 

Background: The frequent systemic side effects associated with the use of systemic carbonic anhydrase inhibitors have adversely affected the compliance to treatment in glaucoma patients, obviating their long-term use. The introduction of the topical CAI[1], dorzolamide, has further reduced their use. However, the tolerability of dorzolamide in patients who have been intolerant to systemic CAIs has not been evaluated prospectively.

Objectives: To study the tolerability and efficacy of dorzolamide (a topical CAI) in a selected group of glaucoma and ocular hypertensive patients who have been intolerant to systemic CAI.

Methods: A 3 month prospective study was conducted in 39 patients. Following recruitment, patients were evaluated on the day of switching from systemic CAI to dorzolamide and for five more visits. The SF-36 health assessment questionnaire was used to evaluate changes in well-being and quality of life, and the intraocular pressure was measured periodically.

Results: Within 4 weeks of switching from systemic CAI to dorzolamide, the mean health assessment scores improved significantly in seven of the eight categories of the SF-36, and remained generally unchanged for the rest of the study. No significant differences were noted between the mean IOP[2] on day 0 and the following measurements throughout the 84 days of dorzolamide therapy.

Conclusion: In glaucoma patients who were intolerant to systemic CAI, topical CAI dorzolamide offers a similar efficacy and better tolerability.

This paper describes "Health Value Added" – an innovative model that links performance measurement to strategy in health maintanance organizations. The HVA[1] model was developed by Maccabi Healthcare Services, Israel’s second largest HMO[2], with the aim of focusing all its activities on providing high quality care within budgetary and regulatory constraints. HVA draws upon theory and practice from strategic management and performance measurement in order to assesses an HMO’s ability to improve the health of its members. The model consists of four interrelated levels – mission, goals, systems, and resources – and builds on the existence of advanced computerized information systems that make comprehensive measurements available to decision makers in real time. HVA enables management to evaluate overall organizational performance as well as the performance of semi-autonomous units. In simple terms, the sophisticated use of performance measures can help healthcare organizations obtain more health for the same money.

Background: Ventilator-dependent patients represent an increasing clinical, logistic and economic burden.  An alternative solution might be monitored home care with high-tech ventilatory support systems. 

Objectives: To explore the implications of such home-care management, such as its impact on quality of life and its cost-effectiveness, and to assess the practical feasibility of this mode of home care in Israel.

Methods: We surveyed 25 partly or fully home-ventilated patients (17 males and 8 females), average age 37.6 years (range 1–72), who were treated through a home-care provider during a 2 year period.

Results: Most patients (n=18) had a neuromuscular respiratory disorder.  The average hospital stay of these patients prior to entry into the home-care program was 181.2 days/per patient.  The average home-care duration was 404.9 days/per patient (range 60–971) with a low hospitalization rate of 3.3 ± 6.5 days/per patient.  The monthly expenditure for home care of these patients was one-third that of the hospital stay cost ($3,546.9 vs. $11,000, per patient respectively).  The patients reported better quality of life in the home-care environment, as assessed by the Sickness Impact Profile questionnaire. 

Conclusions: Home ventilation of patients in Israel by home-care providers is a practical and attractive treatment modality in terms of economic benefits and quality of life.
 

One of the most important issuesfor a country, its population and doctors is the effective use of its health system. The tremendous waste of resources. To combat this, and at the same time ensure that medical quality plays a role when making decisions on interventions, it is essential to equip doctors and clinic directors with information on the quality of the medical care they are providing. In order to assist clinic directors in maitaining medical quality, Clalit Health Services has developed comparative medical indices enabling doctors to compare their performance to that of their colleagues, as well as to the standard and their performance over time. The development of an index to evaluate the quality of medical treatment offered in clinics provides doctors and the health system with an essential tool to lessen the existing variation among doctors and to enhance and evaluate performance.

Background: Urinary incontinence in older women is common. Its characteristics and impact on quality of life is not well established since these women are usually reluctant to tell their healthcare providers about the problem.

Objective: To determine the characteristics of urinary incontinence in women and the manner in which it affects patients quality of life.

Methods: Twenty family physicians were requested to distribute a questionnaire to the first 25 consecutive women aged 30 to 75 years who visited their clinic for any reason. The questionnaire covered general health issues, symptoms of urinary incontinence, and quality of life.

Results: A total of 418 women, mean age 50.0 ± 11.8 years, completed the questionnaire (84% response rate). Of these, 148 (36%) reported having episodes of urinary incontinence. Urinary incontinence was found to be associated with older age, menopause, obesity and coexisting chronic disorders. Sixty percent of the women with urinary incon­tinence found it to be a disturbing symptom, and 44% reported that it had a detrimental effect on their quality of life. Only 32% of the affected women had sought medical advice, half of them from their family physician. Treatment was recommended to 66% of those who sought help, and in about two-thirds of these it brought some measure of relief.

Conclusions: Urinary incontinence is a common com­plaint among women attending primary care clinics, but it does not receive appropriate attention, Though it often adversely affects quality of life, only a small proportion of women seek medical advice. Family physicians should raise the issue as a part of the routine general health check-up.
 

Objective: To explore the putative effect of cardiac rehabilitation programs on the health-related quality of life’ and ‘return to work’ in pre-retirement patients one year after coronary artery bypass grafting.

Methods: Of the 2085 patients aged 45-4 who survived one year after CABG and were Israeli residents, 145 (6.9%) had participated in rehabilitation programs. Of these, 124 (83%) who answered QOL questionnaires were individually matched with 248 controls by gender, age within 5 years. and the time the questionnaire was answered. All patients had full clinical follow-up including a pre-operative interview. The Short Form-36 QOL questionnaire as well  as a specific questionnaire were mailed to surviving patients one year after surgery. Study outcomes included the scores on eight scales and two summary components of the SF-36, as well as return to work’ and ‘satisfaction with medical services’ from the specific questionnaire. Analysis was done for matched samples.

Results: Cardiac rehabilitation participants had signifi­cantly higher SF-36 scores in general health, physical functioning, and social functioning. They had borderline significant higher scores in the physical summary component of the SF-36. The specific questionnaire revealed significantly better overall functioning, higher satisfaction with medical care. and higher rate of return to work. While participants in cardiac rehabilitation and their controls were similar in their socio­-demographic and clinical profiles, participating patients tended to be more physically active and more fully employed than their controls.

Conclusions: Rehabilitation participants had a self-per­ception of better HRQOL, most significantly in social function­ing. Our findings of more frequent return to work and higher satisfaction with medical care should induce a policy to encourage participation in cardiac rehabilitation programs after CABG.
 

The Management of a 750-bed tertiary care university hospital that serves the Jerusalem area and nationwide referrals initiated a total overhaul of all its supporting systems. This program, with parallel contingency plans, ensured a smooth transition of all computer-depended and othe services into the year 2000. Because this extraordinary project proved successful, its outcomes are noe being utilized as a unique impetus for implementation of hospital-wide continuous quality improvement programs. This paper reports how the established QI procedures, which were introduced also during the campaign, are now being activated from the baseline of those outcomes that have provided absolute efficacy in all hospital activities. The success of the campaign was achieved through the total involvement of all staff. This involvement was enhanced by the popular appeal of the dramatic deadline of the date 2000, as well as by focusing attention on personnel dynamics. Strategies for sustaining the momentum must be considered.

Background: Cefuroxime is a second-generation cephalosporin antibiotic used widely for the treatment of various infections.

Objectives: To assess the appropriateness of cefuroxime usage as well as the long-term impact of re-feeding the results to prescribing physicians.

Methods: Drug utilization evaluation involved three data-collecting periods, each comprising 6 weeks, during which all patients receiving cefuroxime were evaluated. Results of phase I were distributed to all physicians in a newsletter and departmental lectures; phase II was announced and conducted 6 months later. An identical phase III was unannounced and conducted one year after phase II. The study included all patients receiving cefuroxime during the three phases. The main outcome measure was appropriateness of initiation, and continuation beyond 3 days, of empirical treatment. Appropriateness was determined according to a prepared list of indications based on the literature and the hospital's protocols.

Results: Cefuroxime was initiated appropriately in 104 of 134 patients (78%) in phase I, in 85 of 100 (85%) in phase II, and in 93 of 100 (93%) in phase III (P<0.001). Cefuroxime was continued appropriately after 3 days in 58/134 (43%), 57/100 (57%) and 70/100 (70%) respectively (P<0.001). The total number of appropriate treatment days out of all treatment days increased from 516 of 635 (81%) in phase I, to 450 of 510 (88%) in phase II, to 485 of 509 (95%) in phase III (P<0.001). The principal reason for cefuroxime usage was community-acquired respiratory tract infection.

Conclusion: Drug utilization evaluation may provide valuable data on the usage of a particular drug. This information, once re-fed to physicians, may improve utilization of the particular drug. This positive effect may be prolonged beyond the immediate period of observation.

Background: Hallway medicine is an integral part of physicians' medical culture, but little is known about it.

Objective: To characterize the practice of hallway medicine among hospital physicians, both as providers and consumers.

Methods: We conducted a survey of 112 randomly chosen hospital physicians at the Soroka Medical Center in Beer Sheva, Israel between November 1997 and May 1998. A self-administered 39-item questionnaire was used that included sociodemographic data, the extent to which hallway medicine is practiced, and satisfaction from and attitudes to it.

Results: Of the 112 selected physicians, 111 responded (99.1%). Of these, 91 (82%) had been asked by their colleagues to provide hallway medicine. Most of them (91%) agreed because of "willingness to help," because "it's unpleasant to refuse," or "it's the acceptable thing to do." Most of the requests (72%) were unscheduled and time consuming (41% up to 10 minutes and 21% more than 20 minutes). Records were kept in only 36% of the cases and follow-up in 62%. Physicians who provided hallway medicine were also consumers of it (P<0.001), based on personal acquaintance, time saved and easy accessibility. In general, the attitude to hallway medicine was negative (54%) or ambiguous (37%). Most requests for hallway medicine were made to Israeli-trained physicians, surgeons or gynecologists, and senior physicians.

Conclusions: Hallway medicine is practiced frequently among hospital physicians. A formal organization of health care service within medical centers might provide physicians with better medical care and reduce potential ethical, medical, legal, psychosocial and economic problems.
