Objectives: To describe and analyze how PCPs[1] in the IDF[2] view their roles as primary care providers and to characterize how they perceive the quality of the medical care that they provide.

Methods: We conducted a survey using a questionnaire that was mailed or faxed to a representative sample of PCPs. The questionnaire included demographic background, professional background, statements on self-perception issues, and ranking of roles as a PCP in the IDF.

Results: Statements concerning commitment to the patient were ranked higher than statements concerning commitment to the military organization. Most physicians perceive the quality of the medical care service that they provide as high; they also stated that they do not receive adequate continuous medical education.

Conclusions: Our survey shows that PCPs in the IDF, like civilian family physicians, perceive their primary obligation as serving the needs of their patients but are yet to take on the full role of “gatekeepers” in the IDF’s healthcare system. We conclude that the Medical Corps should implement appropriate steps to ensure that PCPs are prepared to take on a more prominent role as “gatekeepers” and providers of high quality primary medical care.

Background: Burnout is a professional occupational disease that puts both physicians and patients at risk. Triggered by the increase in burnout levels among physicians, the European Forum of Medical Associations and the World Health Organization issued a statement in March 2003 expressing serious concerns about the situation, urging all national medical associations to increase awareness of the problem, monitor it and study its causes in order to develop preventive strategies.

Objectives: To compare burnout levels in two separate samples of primary care physicians measured in the mid-1990s, with burnout levels in a similar but small and independent sample, assessed in 2001; and to outline the theoretical bases of burnout.

Methods: Altogether, 508 primary care physicians employed by Clalit Health Services responded anonymously to a self-report questionnaire. The samples were not representative and included family physicians, pediatricians and clinic directors.

Results: Burnout levels were significantly higher in the 2001 sample than in the mid-1990s samples, especially among clinic directors.

Conclusions: Despite methodologic limitations of the study, the findings suggest that burnout levels may be increasing among primary care physicians in Israel. This may be due to substantial increases in workload and role conflicts, following implementation of the Health Insurance Law and Patients’ Rights Act. Because these findings are consistent with the trend in Europe, this situation cannot be ignored, and systematic studies of burnout among all medical specialties should be carried out to uncover current sources of the syndrome and to devise measures of prevention and treatment.
 

Background: Primary pulmonary hypertension is a rare disorder, characterized by progressive pulmonary hypertension and right heart failure. It may be familial or sporadic. Mutations in bone morphogenetic protein receptor II (BMPR2), a member of the transforming growth factor-beta receptor superfamily of receptors, underlie many cases of the disorder.

Objectives: To perform molecular analysis of a patient with familial PPH[1] and provide her and her family with suitable genetic counseling.

Methods: DNA was extracted from 10 ml whole blood, and the BMPR2 gene was screened for mutations. Individual exons were amplified by polymerase chain reaction and sequenced. Mutation confirmation and molecular characterization of additional family members was performed using restriction enzyme analysis followed by appropriate genetic counseling.

Results: We identified a novel T to C missense mutation expected to result in substitution of arginine for a conserved cysteine in the ligand-binding domain of BMPR2. Screening of family members demonstrated the presence of the mutation in the father and a younger asymptomatic sister of the index patient.

Conclusions: Molecular diagnosis in PPH allows for identification of at-risk family members and raises the option of earlier diagnosis and possibly instituting earlier treatment in affected individuals. However, molecular screening of asymptomatic family members raises difficult ethical questions that can only be resolved by conducting large multicenter prospective studies in BMPR2 carriers.

The complexity of medical problems is a well-recognized phenomenon. In the presence of economic and cultural restrictions, medical decision-making can be particularly challenging. This paper outlines a system of analysis and decision-making for solving such problems, and briefly describes a case study in which the method was used to analyze the case of antibiotic overprescribing in a large health maintenance organization. The purpose of the study was to determine if a technique for problem-solving in the field of engineering could be applied to the complex problems facing primary care. The method is designated Systematic Inventive Thinking and consists of a three-step procedure: problem reformulation, general search-strategy selection, and an application of idea-provoking techniques. The problem examined is the over-prescribing of antibiotics by general practitioners working in Maccabi Healthcare Services, an HMO[1] serving one and a half million patients in Israel. The group of healthcare professionals involved in the discussions generated 117 ideas for improving antibiotic use. Six of these ideas were then implemented in a national campaign in the winter of 2000/1 and 2001/2. During this period, a significant reduction in per-visit antibiotic purchasing was observed for influenza visits (from 79.2 per 1,000 to 58.1 per 1,000, P < .0001), but not for other categories of visits. The SIT[2] methodology is a useful technique for problem-solving and idea generation within the medical framework.

Background: Unexplained pulmonary hypertension is assumed to occur mainly in young adults.

Objectives: To describe the features of the disease in older patients and compare them to those in PHT[1] patients of all ages.

Methods: We conducted a retrospective evaluation of the files of patients over 65 years of age in whom UPHT[2] was diagnosed between 1987 and 1999 at two PHT centers serving a population of 4 million. Patients were followed for survival until March 2003. Clinical variables of the study patients were compared to those in PHT patients of all ages.

Results: The study group included 14 patients, 10 females and four males, with a mean age of 70.5 ± 6.7 years. The calculated mean annual incidence of UPHT for the study population was one new case per year per million persons. Seven patients (50%) had systemic hypertension. The mean interval from onset of symptoms to diagnosis was 8.3 months. At diagnosis, 64% of patients had functional capacity of III-IV according to the New York Heart Association classification, and 43% had right heart failure. Mean systolic pulmonary artery pressure was 80 ± 21 mmHg, peripheral vascular resistance 11.7 ± 7 mmHg/L/min, cardiac index 2.16 ± 0.81, and mean right atrial pressure 10.5 ± 5.9 mmHg. Median survival time was 43 months; survival rates for 1 year, 3 years and 5 years were 92.6%, 50%, 40%, respectively. Compared to data from the U.S. National Institute of Health Registry, UPHT in older patients is more common in females, but the incidence as well as clinical, hemodynamic and survival parameters are similar to those in PHT patients at any age.

Conclusions: UPHT occurs in the elderly more frequently than previously thought, with similar features in PHT patients of all ages. The coexistence of systemic and pulmonary hypertension warrants further investigation.

Background: Corneal erosions, a common and very painful ailment, are traditionally treated with pressure patches and antibiotic ointment but the healing is slow.

Objectives: To report our experience with the use of therapeutic contact lenses for the primary treatment of traumatic corneal erosions.

Methods: During the last 5 years in a single community clinic 65 consecutive patients with traumatic corneal erosions were treated with a corneal contact lens and antibiotic drops as a routine measure. The charts were reviewed for outcome, side effects and complications.

Results: Healing of the corneal erosions occurred within 1 to 3 days in all patients, with minimal or no pain. No corneal infection occurred. One patient had a recurrence that was successfully treated by lens placement.

Conclusions: The therapeutic contact lens with antibiotic drops is a safe and effective method to treat traumatic corneal erosions, and patients can immediately resume their regular activities.

Background: Reperfusion practices have changed markedly over the last few years with the introduction of primary percutaneous coronary intervention. This technique has gained growing popularity in Israel, but little published data are available regarding the delays to primary PCI[1] in real life in this country.

Objectives: To examine temporal trends in time to reperfusion achieved in a large tertiary center over 6 years.

Results: Between 1997 and 2002, 1,031 patients were admitted to our hospital with ST elevation myocardial infarction. Of these, 62% underwent thrombolysis and 38% primary PCI. The proportion of patients referred for primary PCI increased steadily, from 14% in 1997 to 68% in 2002. Door to treatment time among patients referred for thrombolysis or primary PCI was 54 ± 42 and 117 ± 77 minutes, respectively (P < 0.00001). The door to needle time in patients given thrombolysis remained virtually unchanged during the study period at around 54 minutes. In contrast, the door to balloon time has progressively and substantially decreased, from 175 ± 164 minutes in 1997 to 96 ± 52 minutes in 2002.

Conclusions: There is a steady increase in the proportion of patients referred for primary PCI than for thrombolysis. The door to needle delay in patients given thrombolysis substantially exceeds the recommended time. The door to balloon time has declined considerably but still slightly exceeds the recommended time. Given the inherent delay between initiation of lysis and arterial recanalization, it appears from our experience that PCI does not substantially delay arterial reperfusion as compared to thrombolysis. Efforts should continue to minimize delays to reperfusion therapy.
