Background: Colorectal cancer is the second leading cause of cancer mortality in Israel. Unfortunately, compliance  with annual fecal occult blood testing is very low.

Objective: To assess the effectiveness of interventions to increase FOBT[1] screening in primary care clinics in Israel.

Methods: A prospective, randomized study included all 50–75 year old enrollees of six family physicians in two primary care clinics. The register of two physicians, one from each clinic, was allocated to one of three groups. Two FOBT reminder strategies were tested: a physician reminder (753 patients), and a patient reminder that was either a phone call (312 patients) or a letter (337 patients). The control group (913 patients) of physicians continued administering their regular level of care. The main outcome measure was the percentage of patients undergoing FOBT screening in each study arm at the conclusion of the one year study period.

Results: In the intervention groups 14.3% (201/1,402) were screened using the FOBT over the course of the study year. Using an intent-to-screen analysis, the screening rate in the physician and patient reminder groups was significantly higher than in the control group(16.5 and 11.9%,vs. 1.2% respectively, P < 0.0001). Phone reminders were significantly more efective as compared to letters (14.7 vs. 9.2%, P = 0.01).

Conclusions: Our study has shown the benefit of various FOBT reminder systems, especially those centered around the family physician. Further research should focus on this area, in conjunction with other novel approaches.

Background: Family physicians coordinate the care of their patients and follow them in a longitudinal manner. Do they have a role to play while their patients are hospitalized? Does the system of care expect them to play a role, and how does it support or integrate it?

Objectives: To discuss the various models of relations between hospital and primary care physicians in the world as compared to those in Israel.

Method: Short cases are reported describing the author’s personal experiences and difficulties encountered in a family practice.

Discussion: Identifying and defining problems encountered, as well as their origin and development within the history and evolution of the system of delivery of care in Israel, will lead to some suggestions for a possible solution. Maturation of the system, especially education of the junior staff within the hospital system, is still needed to facilitate the hospital-physician relationship.

Conclusion: More active participation of the family physician offers added value to patients’ management during their hospital stay and is welcomed by them. The full implementation of a system promoting continuity of care requires further attempts at developing suitable models of cooperation between hospital and family physicians.
 

Background: The rapidly increasing costs of healthcare pose a major challenge to many governments, particularly those of developed countries. Health policy makers in some Western European countries have adopted the policy of a strong primary healthcare system, partly due to their recognition of the value of primary care medicine as a means to restrain costs while maintaining the quality and equity of healthcare services. In these countries there is a growing comprehension that the role of the family physician should be central, with responsibility for assessing the overall health needs of the individual, for coordination of medical care and, as the primary caregiver, for most of the individual’s medical problems in the framework of the family and the community.

Objectives: To describe primary care physicians in Israel from their own perception, health policy makers' opinion on the role PCPs should play, and patients' view on their role as gatekeepers.

Methods: The study was based on three research tools: a) a questionnaire mailed to a representative sample of all PCPs employed by the four sick funds in Israel in 1997, b) in-depth semi-structured interviews with key professionals and policy makers in the healthcare system, and c) a national telephone survey of a random representative sample of patients conducted in 1997.

Results: PCPs were asked to rank the importance of 12 primary functions. A total of 95% considered coordination of all patient care to be a very important function, but only 43% thought that weighing economic considerations in patient management is important, and 30.6% thought that 24 hour responsibility for patients is important. Also, 60% of PCPs have undergone specialty training and 94% thought that this training is essential. With regard to the policy makers, most preferred highly trained PCPs (board-certified family physicians, pediatricians and internists) and believed they should play a central role in the healthcare system, acting as coordinators, highly accessible and able to weigh cost considerations. Yet, half opposed a full gatekeeper model. They also felt that the general population has lost faith in PCPs, and that most have a low status and do not have adequate training. Regarding the patients’ viewpoint, 40% preferred that the PCP function as their “personal physician” coordinating all aspects of their care and fully in charge of their referrals; 30% preferred self-referral to sub-specialists, and 19% preferred their PCP to coordinate their care but wanted to be able to refer themselves to specialists.

Conclusions: In order to maintain high quality primary care, it is important that all PCPs have board certification. In addition, PCP training systems should emphasize preventive medicine, health promotion, health economy, and cost-effectiveness issues. Efforts should be make to render PCPs a central role in the healthcare system by gradually implementing the elements of the gatekeeper model through incentives rather than regulations.
 

Background: Breast cancer is the most common malignancy among women in Israel and throughout the world. Israeli women aged 50–75 years are advised to undergo a mammographic screening examination every 2 years. However, the lack of a structured referral system is reflected in the low utilization rate of mammography.

Objectives: To describe an innovative program in which family physicians in an urban clinic developed a model framework for referrals, coordinated with radiologists and surgeons, aimed at increasing compliance among women referred for mammography.

Methods: A community-based study was conducted, outside of the regular reception hours, in a neighborhood practice with a population of 527 women aged 50–75. A referral system under the supervision of family physicians was designed, and the women received appointments for mammography at specified days and hours. The results of the examination were sent to the physician who used dedicated time to continue the diagnostic and/or therapeutic process, as appropriate. At the physician’s instructions a research assistant contacted the women who did not keep their appointments and scheduled a second appointment.

Results: In 1993, the year prior to the study, when women referred themselves for mammography, the utilization rate was 9%. During the study year the utilization rate was 77%. Women born in Europe or America had higher compliance rates than women born in Asia or Africa (81% vs. 72%, respectively). Married women were more compliant than unmarried women (81% vs. 70%, respectively). No correlation was found between compliance and age, family history of cancer in general, or breast cancer in particular. Six new cases of breast cancer were detected.

Conclusions: The initiative of family physicians increased the utilization of mammography among women under their care. Family physicians allocated time outside of their regular reception hours for the program. A relatively large number of new malignancies were found, but this impression should be confirmed or negated by a large-scale study using the same methods.
 

Background: *Previous descriptive studies have demonstrated the problematic nature of physicians' attitudes toward battered women. However, little empirical research has been done in the field, especially among the various medical specialties.

Objectives: To compare the approach and feelings of competence regarding the care of battered women between primary care and non-primary care physicians. The non-primary care physicians who are likely to encounter battered women in the ambulatory setting are gynecologists and orthopedists.

Methods: A self-report questionnaire formulated for this study was mailed to a random sample of 400 physicians working in ambulatory clinics of the two main health maintenance organizations in Israel (300 primary care physicians, 50 gynecologists and 50 orthopedists).

Results: In both physician groups, treating battered women tended to evoke more negative emotional states than treating patients with infectious disease. The most prevalent mood state related to the management of battered women was anger at her situation. Primary care physicians experienced more states of tension and confusion than non-primary care physicians and had lower perceived self-efficacy and self-competence in dealing with battered women.

Conclusions: Though both physician groups exhibited negative feelings when confronting battered women, the stronger emotion of the primary care physicians may indicate greater sensitivity and personal awareness. We believe that more in-service training should be introduced to help physicians at the undergraduate and postgraduate levels to cope both emotionally and professionally with these patients.

Background: Israeli physicians are very familiar with the problem of interruptions during encounters with patients. However, a thorough search of the medical literature revealed only one report of this problem from Israel, and none from other countries.

Objectives: To characterize the phenomenon of interruptions to the patient-physician encounter in a clinic in Dimona and to assess the effect of an intervention program designed to reduce the magnitude of this problem.

Methods: During an 8 day work period in March 1997 all patient-physician encounters were recorded and characterized. An intervention program was then designed and implemented to reduce the number of interruptions. Data were again collected a year after the initial data collection.

Results: During the 8 day study period prior to the intervention program there were 528 interruptions to 379 encounters (mean of 1.39 per encounter). The main causes of interruptions were entrance of uninvited patients to the examination room (31%) and telephone calls (27%). Most of the interruptions occurred during the morning hours between 8 and 10 a.m. (45%) and at the beginning of the week (Sunday 30%). After the intervention program there were 402 interruptions to 355 encounters (mean of 1.13 per appointment, P=0.21).

Conclusions: There was no statistically significant improvement in the number of interruptions following the intervention program. This finding is either the result of a local cultural phenomenon, or it indicates a national primary care health system problem that may require a long-term educational program to resolve it. Further research is needed on the magnitude, causes and consequences of interruptions in family practice and, if warranted, methods will have to devised to cope with this serious problem.

Background: The reasons that patients consult the clinic physician for common minor symptoms are not clearly defined. For seasonal epidemic events such as flu-like symptoms this characterization is relevant.

Objectives: To identify the factors that prompt patients to seek medical attention, and correlate patient behavior with different demographic and disease variables.

Methods: A random sample of 2,000 enrolled people aged 18–65 years and registered with eight primary care clinics located throughout Israel were asked to report whether they had had flu-like symptoms within the previous 3 months.  Those who responded affirmatively (n=346) were requested to complete an ad hoc questionnaire evaluating their treatment-seeking behavior.

Results: A total of 318 patients completed the questionnaire (92% response rate), of whom 271 (85%) consulted a physician and 47 (15%) did not. Those who sought medical assistance had more serious symptoms as perceived by them (cough, headache and arthralgia) (P<0.05), and their main reason for visiting the doctor was “to rule out serious disease.”  Self-employed patients were more likely than salaried workers to visit the clinic to rule out serious disease (rather than to obtain a prescription or sick note or to reassure family). They also delayed longer before seeking treatment (P=0.01).

Conclusion: In our study the majority of individuals with flu symptoms tended to consult a physician, though there were significant variations in the reasons for doing so, based on a combination of sociodemographic variables. We believe these findings will help primary care physicians to characterize their practices and to program the expected demand of flu-like symptoms.

Background: Smoking rates have decreased in western countries as well as in Israel during the past 20 years.

Objectives: To estimate current rates of smoking and smoking cessation, and to assess factors associated with smoking and smoking cessation in family practice.

Methods: Prospective face-to-face interviews were conducted with 1,094 subjects, aged 16 years or older, registered in a family practice.

Results: Of all subjects studied, 746 (68.2%) were non-smokers, 237 (21.7%) were current smokers, and 111 (10.1%) had stopped smoking. Overall, 31.8% of the males and 13.8% of the females were current smokers, and 20.1% males and 2.4% females had stopped smoking. Current smoking and smoking cessation rates were significantly and inversely associated with age among males and females. Smoking rates were higher among males and females who were married, had 10-12 years of education, and among males of North African origin and females of Israeli origin. The number of cigarettes smoked per day was associated with smoking and smoking cessation in males, but not in females. The highest rate of quitting occurred among males who smoked 25 cigarettes per day. In a multiple regression analysis, gender and the number of cigarettes smoked per day were the most significant factors that predicted smoking cessation. The most common reason for stopping was the appearance of new signs of illness or the development of a new chronic disease, followed by a physician's recommendation to quit smoking.

Conclusions: Female smokers and male smokers who smoke less than 25 cigarettes per day are the least likely to quit smoking. Future programs should be designed for and targeted at these groups of patients.

Background: Osteoporosis is the most common human bone disease. It affects millions of persons throughout the world and its prevalence will increase as the population ages worldwide.

Objective: To assess Israeli physicians' attitudes and knowledge with regard to management of osteoporosis.

Methods: A questionnaire was mailed to 1,900 Israeli physicians concerning their attitudes to the management of osteoporosis, their prescribing habits, and their knowledge on the pharmacological treatment of the disease.

Results: Replies were received from 19% of the physicians. The respondents encouraged physical activity and cessation of smoking for all women, and prescribed estrogen replacement as the main treatment for 50-year-old women. A relatively low level of knowledge was found regarding the adequate dosage of several of the pharmacological treatments.

Conclusions: The findings of the present study stress the need to provide clear guidelines and to extend physicians' knowledge regarding the management of osteoporosis.

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: Most countries today are experiencing an accelerated pace of population aging. The management of the elderly housebound patient presents a special challenge to the family physician.

Objectives: To investigate a series of home visits to housebound patients, the therapeutic procedures used, the equipment needed, and the diagnostic conclusions reached.

Methods: The details of 379 consecutive home visits to housebound patients were recorded by 91 family doctors serving 125,000 patients in Israel.

Results: The average age of the patients was 76.1 years. The vast majority of the visits were during office hours (94%). In 24.1% it was the doctor who decided to make the home visit on his/her own initiative. The most common initial reason for a home visit was undefined general symptoms, but the doctor was usually able to arrive at a more specific diagnosis after the visit. Medications were prescribed in 59.1% of the visits, and in 23.5% the medication was administered directly by the physician. The commonest drugs used were analgesics and antibiotics. In 19.3% of visits no action at all, other than examination and counseling, was undertaken. The equipment needed included prescription pads (73%), a stethoscope (81%), sphygmomanometer (74.9%), and otoscope/torch (30.6%). Only 15% of visits resulted in referral to hospital.

Conclusions: Home visits to housebound patients serve as a support to caregivers, provide diagnostic information, and help the family with the decision as to when hospitalization is appropriate. The specific medical cause for the patient being housebound had little effect on the process of home visiting.
 

Background: Dyslipidemia and obesity serve as risk factors for the development of atherosclerotic cardiovascular disease. Fasting is sometimes recommended for treating these conditions. This study was undertaken to try to resolve conflicting results reported in the literature.

Objectives: To study the effect of fasting (0 calories, with free intake of fluids) for 3-5 days on plasma concentration of triglyceride, cholesterol and apolipoprotein B.

Methods: Physicians, about to begin a hunger strike, were divided into four groups: normolipidemic non-obese men (group 1), two moderately obese men and two men with type IV hyperlipidemia (group 2), healthy non-obese women (group 3), and healthy non-obese women on oral contraceptives (group 4). Adherence to fasting was monitored daily by detailed interviews, loss of weight, drop in plasma glucose, presence of ketonuria, progressive rise in serum creatinine and uric acid, and decrease in plasma pH. We monitored their serum glucose, electrolytes, liver function, lipids, lipoproteins and apolipoprotein B on days 0, 3, and 5.

Results: Physicians who adhered to complete fasting lost more than 1.5% of their body weight after 3 days of fasting (n=12), and more than 3.2% at 5 days (n=5). All non-obese normolipidemic males and females (groups 1 and 3) showed an increase in plasma triglyceride (by 28-162%) and very low density lipoprotein cholesterol (by 22-316%) after 3 days of fasting. The obese and hyperlipidemic men (group 2) showed a decrease of 17-63% in their VLDL cholesterol, and the women on oral contraceptives (group 4) showed a 20% decrease in their plasma triglyceride on day 3. Low density lipoprotein cholesterol increased by 13% in group 2, decreased by 7.3% in group 4, and remained unchanged in group 1 and 3. Apolipoprotein B level correlated well with LDL cholesterol in all groups. High density lipoprotein cholesterol changes were inconsistent.

Conclusions: These results help to explain and reconcile previous published reports. The metabolic background of the individual together with the amount of energy consumed affect the behavior of plasma lipids and lipoproteins levels during fasting.
