The Effect of Combined Aspirin and Clopidogrel Treatment on Cancer Incidence

BACKGROUND

Multiple studies have shown an association between aspirin treatment and a reduction in newly diagnosed cancer. Conversely, there are conflicting clinical and laboratory data on the effect of combined clopidogrel and aspirin therapy on cancer incidence, including analyses suggesting an increased cancer risk. No large-scale cohort study has been performed to address this issue in a heterogeneous real-world scenario. We investigated the effect of clopidogrel and aspirin on cancer incidence compared with aspirin alone and no antiplatelet therapy.

METHODS

A population-based historical cohort study of subjects aged ≥50 years covered by Clalit Health Services, an Israeli health maintenance organization, was performed. Patients treated with the newer antiplatelet drugs, prasugrel or ticagrelor, which, like clopidogrel, inhibit adenosine diphosphate receptors, and those with prior cancer were excluded. Prescription records of antiplatelet medication were retrieved.

RESULTS

The cohort included 183,912 subjects diagnosed with 21,974 cancer cases based upon the International Classification of Diseases, Ninth Revision. Dual aspirin and clopidogrel was prescribed in 9.6%, while 49% received aspirin alone and 41% used neither. Compared with nonusers, there was a lower risk of cancer in subjects exposed to aspirin with (hazard ratio [HR] 0.46; 95% confidence interval [CI], 0.44-0.49) or without clopidogrel (HR 0.54; 95% CI, 0.52-0.56), on long-term follow-up. Combined treatment was associated with a lower cancer risk than the aspirin-only group (HR 0.92; 95% CI, 0.86-0.97).

CONCLUSIONS

Dual clopidogrel and aspirin treatment is safe regarding the cancer risk. This study generates the hypothesis that clopidogrel may reduce cancer incidence.

The Ecology of Medical Care Among Israeli Military Aviators

BACKGROUND

The ecology of medical care model has been used in various populations with varying results. We aimed to apply this model in the population of Israeli Air Force (IAF) aviators.

METHODS

An anonymous questionnaire was presented to all Israeli Air Force aviators during their mandatory yearly check-up over 1 yr starting on November 26th, 2012. The questionnaire contained items on demographic, personal, and military details, as well as items on the presence of clinical symptoms, and various health care contacts in the previous month. We assessed the differences between career and reserve personnel using a X2 test.

RESULTS

There were 325 aviators who completed the questionnaire (2 women, 132 reserves). Clinical symptoms were reported by 62.5% of the responders. Over half (52.6%) had any health care encounter: 23.7% with a dentist, 17.9% with non-MD therapists, 12.6% with a specialist, and 11.7% with a primary physician. A significant difference between reserve and career personnel was found only in primary care visits. Out of the aviators who reported having clinical symptoms, 70.9% did not visit a physician. Of those who did not seek medical care, 42.4% reported that the symptoms were viewed as unimportant, 41% thought they would disappear by themselves, 40.3% could not find time for treatment.

CONCLUSIONS

Aviators in the IAF have similar rate of clinical symptoms as in other unselected populations. Those who report symptoms usually do not visit a physician for treatment. When they do seek advice it is mostly from non-MD practitioners.Gordon B, Levy Y, Yemini T, Carmon E, Erlich Y, Hermoni D. The ecology of medical care among Israeli military aviators.

Living outliers: experiences, insights and narratives of exceptional survivors of incurable cancer

AIM

Unexplained prolonged survival given a diagnosis of incurable advanced cancer is a puzzling phenomenon that recently has attracted more scientific research. The purpose of this study was to add to the understanding of how exceptional patients perceive and explain their unusual experience.

METHODS

We recruited patients for interviews from a population registry, patients with advanced lung or pancreatic malignancy who experienced exceptional survival.

RESULTS & CONCLUSION

In total, 15 participants were interviewed. The main recurrent themes in most of the interviews were patient-doctor communication, family support and the patient's proactive attitude. In this study, patients attribute their longevity to relationships with their doctor and their family - not the type of treatment they received. Further research on this phenomenon is needed.

Late successful weight reduction and maintenance among overweight and obese adults--a two-year retrospective study

AIMS

Our purpose was to identify those factors associated with successful late weight reduction and maintenance among overweight and obese adults who failed to achieve initial weight reduction success.

METHODS

Medical computerized files of 5254 participants, who failed to achieve ≥ 5% weight reduction after an initial 6-month period, were retrospectively analyzed to identify predictors associated with late successful weight reduction and maintenance (≥ 5% during the first and second years, respectively). Over 40 independent variables were analyzed. The main outcome was the percentage of weight change.

RESULTS

Significant predictors of late success in weight reduction were as follows: more visits to a dietitian, higher baseline BMI, and any initial weight reduction (0-5%) (OR=3.69, compared with participants who initially gained weight). The use of insulin (OR=0.499) and the presence of hypertension (OR=0.75) were significantly correlated with failure to reduce weight. Predictors of late maintenance were as follows: more visits to a dietitian, higher baseline BMI, any initial weight reduction, a younger age, not being treated with insulin (OR=0.316), and more weighings (OR=1.68).

CONCLUSIONS

A substantial sub-group of obese and overweight patients was able to reduce their weight at a slower rate than the defined successful time of 6 months. Significant specific predictors were identified. Diabetic and hypertensive patients are at a significantly higher risk of failure to reduce and maintain weight. Using regression models, we calculated the probability of successful late weight reduction. This calculation could serve as a clinical tool for a professional team.

Thyrotropin levels within the lower normal range are associated with an increased risk of hip fractures in euthyroid women, but not men, over the age of 65 years

CONTEXT

The contemporary literature on the relationship between serum TSH levels and osteoporotic fractures in euthyroid individuals is limited by conflicting results and analyses conducted on a small number of fractures.

OBJECTIVE

Our objective was to examine the association between the normal range of variation of TSH and the incidence of hip fractures in male and female euthyroid patients aged 65 years or older.

DESIGN AND SETTING

We performed a population-based historical prospective cohort study within the Clalit Health Services population.

PARTICIPANTS

Clalit Health Services members aged ≥65 years with at least 1 TSH measurement during the year 2004. We excluded patients with preexisting hip fracture, thyroid disease, malignancy, or chronic kidney disease.

OUTCOME MEASURES

The primary outcome was hip fracture, and the secondary outcome was any other osteoporotic fracture.

STATISTICAL ANALYSIS

Adjusted odds ratios comparing episodes of each outcome across 3 TSH groups (low, 0.35-1.6 mIU/L; intermediate, 1.7-2.9 mIU/L; high, 3-4.2 mIU/L) were generated using logistic regression models.

RESULTS

The 14 325 included participants suffered from 514 hip fractures (mean follow-up, 102 ± 3 months). Women, but not men, in the lowest TSH group had a higher incidence of hip fractures (odds ratio = 1.28, 95% confidence interval = 1.03-1.59, P = .029) when compared with the intermediate group, after multivariate adjustment for age, comorbidities, and use of drugs affecting bone metabolism. There was no difference in hip fracture incidence between intermediate- and high-TSH groups. No association was found between TSH levels and other osteoporotic fractures.

CONCLUSIONS

TSH levels within the lower normal range are associated with an increased risk of hip fractures in euthyroid women, but not men, aged 65 years and more.

Assessment of the knowledge and attitudes regarding HIV/AIDS among pre-clinical medical students in Israel

BACKGROUND

Today's medical students are the future physicians of people living with HIV/AIDS (PLWHA). It is therefore essential that medical students possess the appropriate knowledge and attitudes regarding PLWHA. This study aims to evaluate knowledge and attitudes of pre-clinical Israeli medical students and to assess whether their knowledge and attitudes change throughout their pre-clinical studies.

METHODS

A cross-sectional study was conducted among all pre-clinical medical students from the four medical schools in Israel during the academic year of 2010/2011 (a total of 1,470 students). A self-administered questionnaire was distributed. The questionnaire sought student responses pertaining to knowledge of HIV transmission and non-transmission routes, basic knowledge of HIV/AIDS treatment and attitudes towards HIV/AIDS.

RESULTS

The study's response rate was 62.24 percent. Knowledge among pre-clinical medical students was generally high and showed a statistically significant improvement as students progressed through their pre-clinical studies. However, there were some misconceptions, mostly regarding HIV transmission via breastfeeding and knowledge of HIV prevention after exposure to the virus. Students' attitudes were found to include stigmatizing notions. Furthermore, the majority of medical students correlated HIV with shame and fear. In addition, students' attitudes toward HIV testing and providing confidential medical information were contradictory to health laws, protocols and guidelines. Overall, no positive changes in students' attitudes were observed during the pre-clinical years of medical school.

CONCLUSION

The knowledge of pre-clinical medical students in Israel is generally high, although there are some knowledge inadequacies that require more emphasis in the curricula of the medical schools. Contrary to HIV-related knowledge, medical students' attitudes are unaffected by their progression through medical school. Therefore, medical schools in Israel should modify their curricula to include teaching methods aimed at improving HIV-related attitudes and adherence to medical professionalism.

Lipid control in patients with coronary heart disease treated in primary care or cardiology clinics

BACKGROUND

Guidelines recommend low-density lipoprotein-cholesterol (LDL-C) target of <70 mg/dL in patients with coronary disease. However, this goal is not achieved in many patients.

OBJECTIVES

We compared LDL-C control in patients with coronary disease treated by a primary care physician or with the addition of a cardiologist.

METHODS

Included were patients with coronary disease who had full lipid profile. Primary end points included the percentage of patients who achieved the LDL-C goals of <100 mg/dL and <70 mg/dL.

RESULTS

Of the 27,172 patients, 12,965 (47.7%) were followed only by a primary care physician and 14,207 (52.3%) were also followed by a cardiologist. Overall, 18,366 patients (67.6%) achieved the LDL-C goal of <100 mg/dL, and 6517 patients (24%) achieved the LDL-C goal of <70 mg/dL. Patients followed by a cardiologist more frequently achieved the LDL-C goal of <100 mg/dL (74.3% and 60.3%; P < .0001, in patients treated by a cardiologist or by a primary care physician, respectively), as well as the lower LDL-C goal of <70 mg/dL (27.2% and 20.4%; P < .0001, in patients treated by a cardiologist or by a primary care physician, respectively). Differences in LDL-C control remained significant after a multivariate adjustment. Patients followed by a cardiologist were more commonly treated with highly potent statins and with non-statin cholesterol-lowering drugs.

CONCLUSIONS

Among patients with coronary disease, those followed by a cardiologist receive a more aggressive antilipid treatment and more frequently achieve lipids goals. Nevertheless, the disappointingly poor lipid control in both groups warrants an effort to improve adherence for guidelines in both primary care and cardiology clinics.

New-onset diabetes in elderly subjects: association between HbA1c levels, mortality, and coronary revascularization

OBJECTIVE

New-onset diabetes mellitus (DM) in elderly patients is associated with increased risk of diabetes complications and mortality. It is unknown whether glycemic control in this population influences the mortality risk.

RESEARCH DESIGN AND METHODS

The current study was conducted using the computerized database of the Sharon-Shomron District of Clalit Health Services in Israel. Included in the study were subjects 65 years of age and above with new-onset DM. The primary outcome measures were all-cause mortality and coronary revascularization procedures with either percutaneous coronary intervention or coronary artery bypass grafting.

RESULTS

Participants (n = 2,994) were stratified into four groups according to their mean HbA1c levels during the follow-up period (<6.5% [48 mmol/mol], 6.5-6.99% [48-52 mmol/mol], 7-7.49% [53-57 mmol/mol], and ≥7.5% [58 mmol/mol]). During a mean follow-up of 5.54 ± 2.1 years, 1,173 (39.17%) participants died and 285 (9.51%) underwent coronary revascularization. An HbA1c level >7.5% (58 mmol/mol) was associated with a significantly increased all-cause mortality rate (hazard ratio [HR] 1.74 [95% CI 1.2-1.8], P < 0.0001). This difference remained statistically significant after a multivariate model adjusted for the conventional cardiovascular risk factors and for the use of hypoglycemic agents and statins. Kaplan-Meier survival plots revealed lower survival rates in this group of patients. Coronary revascularization rates were highest among subjects with HbA1c 6.5-6.99% (48-52 mmol/mol) (HR 1.6 [1.01-2.4], P < 0.05) and lowest in patients with HbA1c ≥7.5% (58 mmol/mol).

CONCLUSIONS

An HbA1c level >7.5% (58 mmol/mol) is associated with increased risk for all-cause mortality and with a lower revascularization rate in elderly patients with new-onset DM.

Comparison of lipid control in patients with coronary versus peripheral artery disease following the first vascular intervention

Peripheral arterial disease (PAD) is a strong risk factor for cardiovascular morbidity and mortality. Therefore, target low-density lipoprotein (LDL) cholesterol level in patients with PAD is ≤70 mg/dl, similar to patients with coronary artery disease (CAD). However, despite their high cardiovascular risk, patients with PAD less frequently achieve LDL cholesterol goals compared to patients with CAD. We aimed to compare LDL cholesterol control in patients after first coronary or peripheral vascular intervention. Included were patients ≥18 years of age without a history of cardiovascular disease who underwent first coronary or peripheral vascular intervention from 2004 through 2010. Primary end points were percentage of patients who achieved the LDL cholesterol goal of <100 and <70 mg/dl. Of 9,138 patients available for analysis, 7,512 (82.2%) underwent first coronary revascularization and 1,626 (17.8%) underwent first peripheral revascularization. Patients after first coronary revascularization were treated more frequently with any statin and with highly potent statins. Furthermore, they more frequently achieved the LDL cholesterol goals compared to patients after first peripheral intervention. This was true for the LDL cholesterol goal of <100 mg/dl (65% and 46.7%, p <0.0001) and for the lower LDL cholesterol goal of <70 mg/dl (23.3% and 13.3%, p <0.0001). Differences in LDL cholesterol control between the 2 groups remained statistically significant after multivariate adjustment. In conclusion, lipid control in patients with PAD is poor and significantly inferior to that of patients with CAD even after the first vascular intervention.

Effect of ezetimibe on the prevalence of cholelithiasis

AIM: To investigate the prevalence of cholelithiasis among patients treated with ezetimibe.

METHODS: A retrospective, case-control study based on computerized medical records from patients of the Clalit Health Services, Sharon-Shomron region, from 2000 to 2009. Patients 20-85 years of age, who had been treated with ezetimibe and statins or statins only for at least 6 mo, and who had an abdominal ultrasound were included in the study. Collected data included age, gender, ezetimibe treatment duration, presence of hypothyroidism or diabetes, and existence of cholelithiasis as determined by ultrasound. Excluded were subjects after gallbladder resection, with hemolysis, myeloproliferative or inflammatory bowel diseases, and those treated with ursodeoxycholic acid and fibrates. Patients treated with statins and ezetimibe (study group) were compared to patients treated with statins only (control group).

RESULTS: The study group included 25 patients and the control group 168. All patients in the study were treated with statins. The study group included 13 males (52%) and 12 females (48%), the control group 76 males (45%) and 92 (55%) females (P = 0.544). The groups did not differ in age (mean age: 68 ± 8 years, range 53-85 years vs mean age: 71 ± 8 years, range 51-85 years; P = 0.153) or in the rate of diabetic and hypothyroid patients [11 (44%) vs 57 (33%), P = 0.347 in the study group and 5 (20%) vs 23 (14%), P = 0.449 in the control group, respectively]. Patients in the study group were treated with ezetimibe for an average of 798 ± 379 d. Cholelithiasis was found in 4 (16%) patients in the study group and in 33 (20%) patients in the control group (P = 0.666).

CONCLUSION: Ezetimibe does not appear to influence the prevalence of gallstones.

[Evidence-based clinical database--rational use saves time]

During the last decade, the production of medical information has doubled every 14 months. It is predicted that information will double at an even faster rate. This dramatic rate of changing medical knowledge presents a challenge for physicians to keep up to date. Physicians are usually eager for the latest medical information. The late British epidemiologist, Archie Cochrane, developed a relatively new approach using up-to-date medical information. His approach integrates individual clinical expertise with the best available external clinical evidence from systematic research. Through this method new information is located, identified and its significance evaluated. If the new information has been proven to be reliable and relevant, it is integrated into existing information systems to be used by physicians all over the world. This approach is called evidence-based medicine. This review will summarize the four leading clinical databases which are evidence based medicine oriented: Dynamed, Cochrane Library, Trip database and Attract, and short presentation of the best evidence based medicine "secondary literature".

The e-patient: a survey of israeli primary care physicians' responses to patients' use of online information during the consultation

BACKGROUND

The Internet has transformed the patient-physician relationship by empowering patients with information. Because physicians are no longer the primary gatekeepers of medical information, shared decision making is now emerging as the hallmark of the patient-physician relationship.

OBJECTIVES

To assess the reactions of primary care physicians to encounters in which patients present information obtained from the Internet (e-patients) and to examine the influence of the physicians' personal and demographic characteristics on their degree of satisfaction with e-patients.

METHODS

A questionnaire was developed to assess physicians' attitudes to e-patients, their knowledge and utilization of the Internet, and their personal and professional characteristics. Family physicians in central Israel were interviewed by telephone and in person at a continuing medical education course.

RESULTS

Of the 100 physicians contacted by phone, 93 responded to the telephone interviews and 50 physicians responded to the questionnaire in person. There was an 85% response rate. The mean age of respondents was 49 years. Most physicians were born in Israel, with a mean seniority of 22 years. Most had graduated in Eastern Europe, were not board certified and were employees of one of the four health management organizations in Israel. Most physicians responded positively when data from the Internet were presented to them by patients (81%). A number of respondents expressed discomfort in such situations (23%). No association was found between physicians' satisfaction in relationships with patients and comfort with data from the Internet presented by patients.

CONCLUSIONS

Physicians in this sample responded favorably to patients bringing information obtained online to the consultation. Though it may be difficult to generalize findings from a convenience sample, Israeli family physicians appear to have accepted internet use by patients.

[Validation of an international infrastructure and management set of quality indicators for Israeli primary care]

BACKGROUND

Adequate premises, equipment and organization of care are prerequisites for good primary care. The lack of a generally accepted systematic framework for practice management contributes to clinical outcome variations as well as inequalities in health care delivery.

OBJECTIVE

To validate, localize and assess an internationally validated method for practice assessment in primary care in Israel.

METHODS

The international tool contained 6 domains, 171 indicators and 470 items in 32 different aspects of primary health care provision. The instrument was translated into Hebrew. The major assessment in Israel was performed in 30 practices of Clalit Health Services by practice visits of 2 independent observers who completed check lists, structured interviews with the management staff of the clinic, work satisfaction questionnaires of the clinic staff and satisfaction questionnaires to patients at 30 clinics. The data was processed and analysed by SPSS. Frequency distribution and descriptive statistics were computed for all questions. Factor and reliability analysis were used to reduce the remaining items to a reduced number of indicators.

OUTCOMES

From the initial 171 indicators and 470 items, we have managed to downsize the process of evaluation to a feasible size of 57 indicators and 142 items which have been proved as discriminating between the practices on an international level. The Israeli assessment downsized the number of locally discriminating indicators to 50.

CONCLUSIONS/RECOMMENDATIONS

The resulting set of indicators is good and valid for improving the organization and management of general practices. On a national Israeli level there is need for further validation, which will include all the Israeli providers.

Is knowledge a barrier to implementing low back pain guidelines? Assessing the knowledge of Israeli family doctors

OBJECTIVES

To measure knowledge of Israeli low back pain (LBP) clinical practice guidelines among different subgroups of primary care doctors, prior to designing an intervention programme to enhance guideline adherence in practice.

STUDY DESIGN

Confidential mailed survey questionnaire.

SETTING

Family practices in the Haifa and western Galilee district, Israel.

PARTICIPANTS

Random sample of 163 primary care doctors. A total of 134 doctors (82%) completed the questionnaire.

MAIN OUTCOME MEASURES

A Multiple Choice Questionnaire measuring knowledge of the LBP guidelines. Instrument reliability and inter-item reliability were tested in a pilot phase. Content validity was assured by having the Israeli LBP guideline authors involved in a consensus procedure.

RESULTS

Distribution of test scores significantly differentiated professional levels and background variables, demonstrating the instrument reliability. Cronbach's alpha was above 0.91. The average test score was 67.7 [standard deviation (SD) 16.2], family doctors had average scores of 75.2 (SD 9.8), general practitioners (GPs) 57.9 (SD 19) and family practice residents 67.4 (SD 13.2). The difference between the test average scores of family doctors, GPs and residents was significant (P < 0.001). Significant differences were also found for specific variables including the doctor's age, country of medical training and self-report familiarity with the LBP guidelines.

CONCLUSIONS

Striking differences exist between subgroups of primary care doctors regarding their knowledge of LBP guidelines. These differences will require the design of multiple interventions tailored to each subgroup.

Teaching complementary medicine at an academic oncology department

BACKGROUND

The increased use of complementary and alternative medicine (CAM) by patients with cancer is a significant phenomenon in cancer care and suggests the need for increased knowledge by clinicians of these therapies.

METHODS

Aiming at bridging the gap in knowledge of the philosophy and practice of major CAM modalities in cancer care, an elective course was offered to physicians and nurses in a large academic center.

RESULTS

The course also aimed at providing the tools necessary to establish open and trusting clinician-patient dialogue regarding CAM.

CONCLUSIONS

Exposure to the course was successful in improving knowledge and attitudes.

Is patients' sexual orientation a blind spot of family physicians?

Even though certain health needs of gay, lesbian, and bisexual (GLB) patients are unique and different from those of the heterosexual patient, physicians do not usually ask patients about their sexual orientation. This study investigates family physicians' common practice regarding their patients' sexual orientation. Most of the physicians surveyed knew of less than 0.5% GLB patients in their practice; 44.4% did not know of any GLB patients. Only one physician commonly asked his patients about their sexual orientation; other physicians rarely or never asked. Asking patients about their sexual orientation significantly (P < 0.01) predicted the number of GLB patients known to the physician. Asking about patients' sexual orientation is not a common practice for family physicians, and, thus, they are usually unaware of the GLB patients in their practice.

[Percutaneous discectomy and intradiscal radiofrequency thermocoagulation for low back pain: evaluation according to the best available evidence]

Within the framework of evidence-based medicine, high quality randomized trials and systematic reviews are needed for new medical treatment. Clinicians should conscientiously, explicitly and judiciously use the best current evidence in making decisions about the care of individual patients. This paper summarizes the best available evidence from systematic reviews and randomized controlled trials concerning two minimally invasive procedures: percutaneous discectomy and percutaneous intradiscal radiofrequency thermocoagulation. Percutaneous discectomy is a minimally invasive surgical procedure that treats contained, herniated discs. Specific procedures within the class include: manual percutaneous lumbar discectomy, Automated percutaneous lumbar discectomy (APLD) laser discectomy and nucleoplasty percutaneous intradiscal radiofrequency thermocoagulation is a procedure that allows the controlled delivery of heat to the intervertebral disc via an electrode or coil. Results of systematic reviews were retrieved from four leading evidence-based databases: the National Institute for Clinical Excellence--NICE, which is an independent organization responsible for providing national guidance on treatments, the Cochrane Library, which is the largest library world-wide for systematic reviews and randomized controlled trials, the Center for Review and Dissemination (CRD) at the University of York, which undertakes reviews of research about the effects of interventions in health and social care and finally, a search via Medline. The results from those systematic reviews and randomized trials shows that, at present, unless or until better scientific evidence is available, automated percutaneous discectomy and laser discectomy should be regarded as research techniques. Radiofrequency denervation can relieve pain from neck joints, but may not relieve pain originating from lumbar discs, and its impact on low-back joint pain is uncertain.

[The importance of sexual orientation in the medical consultation]

Gay, lesbian, bisexual and transgender (GLBT) patients have unique and different health needs other then those of the heterosexual patient. Although a significant proportion of the population is gay or lesbian, physicians receive little formal training about homosexuality, and the unique health care needs of these patients are often ignored. GLBT patients may have higher rates of depression, suicide attempts, alcoholism, and certain cancers, sexual transmitted and cardiovascular disease. One of the most significant medical risks of these populations is avoidance of routine health care and dissatisfaction due to fear of stigmatization by the medical community. Youth GBLT patients are particularly vulnerable to internal and external pressures, resulting in higher rates of substance and alcohol abuse, suicide, and homelessness. Declining health and loneliness may trouble older GBLT patients, who generally view themselves more positively. Physicians can improve the health care of GBLT patients and their families by maintaining a non-homophobic attitude toward these patients, distinguishing sexual behavior from sexual identity, communicating with gender-neutral terms, and maintaining awareness of how their own attitude affects clinical judgment. Scant research exists with regard to the best ways to teach medical students about the special challenge GBLT patients face. However, the recommendation is to integrate such teaching throughout the entire medical school curriculum. This article includes a summary of the medical literature for the GBLT patients' health care needs and suggests strategies for enhancing the care for this population, as well as incorporating it during the medical education.

The challenge of using the low back pain guidelines: a qualitative research

PURPOSE

Current low back pain (LBP) clinical guidelines have helped to summarize the scientific evidence and research, but have failed to provide tools and guide family physicians (FPs). The purpose of this study is to identify barriers and facilitators for the implementation of LBP guidelines from family FPs' perspective.

METHODS

A qualitative focus group study of FPs in the north of Israel. Purposeful sampling was used to recruit participants, all of them board-certified FPs. Four focus groups were created, and discussions were taped, transcribed and analysed for major themes.

RESULTS

Focus groups findings have expanded the understanding of the intellectual and mental challenges faced by Israeli FPs caring for LBP patients and highlighted the many obstacles to implementing LBP guidelines. Physicians' decision-making, pertaining to LBP, functions on three levels simultaneously: the physicians' agenda based on familiarity with the guidelines; their need to remain grounded in the context of the specific patient-doctor relationship; and the constraints and demands of the physician's workplace, medical system and environment.

CONCLUSIONS

Despite an overall positive attitude towards LBP guideline implementation, FPs found it hard to come to terms with the conflicting dimensions of LBP patient care. The patient-doctor interaction determined the outcome of the encounter, whether it complied with the guidelines and whether the encounter leads to a healing process or to a vicious circle of unnecessary utilization of services.

Promoting lifestyle self-awareness among the medical team by the use of an integrated teaching approach: a primary care experience

OBJECTIVES

Healthy lifestyle is recommended in clinical guidelines for the prevention and treatment of chronic diseases such as cardiovascular disease and diabetes. Research previously identified a gap between lifestyle recommendations and their implementation in clinical practice. In this paper, we describe a pilot educational program aimed to promote providers' awareness of their own lifestyles, and to explore whether increased personal awareness enhances providers' willingness to engage in lifestyle-change discussion with patients.

METHODS

Two primary-care urban clinics in Northern Israel participated in the program, which consisted of a series of six biweekly educational sessions, each lasting 2-4 hours. Each session included both knowledge-based and experiential learning based on complementary medicine modalities. Surveys at the end of the program and a year later provided the program evaluation.

RESULTS

Thirty-five personnel participated in the program. Thirteen (13) of the 20 participants (65%) reported an attitude change regarding eating habits after the program. At 1-year follow up, 24 of the 27 respondents (89%) stated that they were more aware of their eating habits and of their physical activity compared with precourse status. Twenty-three (23) of 27 respondents (85%) stated that after the program they were better prepared to initiate a conversation with their patients about lifestyle change.

CONCLUSIONS

An integrated educational approach based on knowledge-based and complementary and alternative medicine experiential modalities, aimed to facilitate self-awareness, may enhance learners' attitude change. The findings demonstrate readiness of learners to reexamine their lifestyles. Increased self-awareness helped participants to make a positive attitude change regarding eating habits and physical activity and was associated with participants' increased engagement in lifestyle-change discussions with patients. The teaching approach had longstanding effect, noted in the one-year follow-up.

The LBP patient perception scale: a new predictor of LBP episode outcomes among primary care patients

OBJECTIVE

To describe a new tool designed to capture patients' perception of their low back pain (LBP) episodes-the patient perception scale (PPS) and test its ability to predict episode outcomes.

METHODS

Thirty-two family physicians recruited 526 low back pain patients during an office visit. Physicians completed a short questionnaire at the index visit, which included both their assessments of patients' patient perception scale (PPS-doc) and contact information. Patients were then interviewed by telephone within 2 weeks after the index visit, with follow-up telephone contacts at 2, 4, 8 and 12 months. The patient perception scale as reported by the physician (PPS-doc) and patient (PPS-pt), each constituent question, and different combinations were analyzed for their ability to predict patient outcomes.

RESULTS

Patients' responses (PPS-pt) proved predictive for all outcome items. PPS-doc was much less predictive. Measures of patient centeredness did not perform well in this study.

CONCLUSION

By using a short scale based on the patient's perception of pain (PPS-pt), it is possible to predict adverse outcomes of a low back pain episode. The patient perception scale should be evaluated further and perhaps combined with other instruments for targeting care and chronicity prevention efforts in low back pain.

PRACTICE IMPLICATIONS

The PPS-pt could potentially be used as part of the standard initial patient evaluation of new LBP patients, as a proxy for "yellow flags" (markers of psychosocial risk) where a positive score might be the equivalent to high-risk identification. The apparent advantage of this scale is its brevity and simplicity of administration. The separation, through this scale of pain episodes into simple and complex LBP might be a useful tool for helping direct resources and avoiding chronicity.

Factors in the doctor-patient relationship that accentuate physicians' hurt feelings when patients terminate the relationship with them

OBJECTIVE

The present study explores the emotional effect of the injury experienced by physician's, as a consequence of a patient's termination of their relationship.

METHODS

A vignette study using different scenarios describing a patient who switched to another doctor was distributed to 119 family physicians. A three-way ANCOVA analysis was employed. Additionally, physicians' answered an open question asking of situations that elicited negative emotions.

RESULTS

The quantitative results indicated that termination of the relationship by a "high status" patient and/or after a long duration is more emotionally hurtful than termination by a "lower status" patient after a brief relationship. The results of the open question provided an additional insight into the emotional impact of the doctor's hurt feelings on the doctor-patient relationship.

CONCLUSIONS

The severity and consequences of the emotional injury experienced by physicians when patients decide to transfer to another physician are influenced by factors related to the patient, physician and the relationship between them.

PRACTICE IMPLICATIONS

We discuss the implications of our results on the understanding of the emotional injury and consequent impaired function and possible "burn-out" in physicians and explore the possibility of educating doctors to heightened awareness and consequently enhanced ability to cope with such situations.

Aggregation of qualitative studies--From theory to practice: Patient priorities and family medicine/general practice evaluations

OBJECTIVE

Aggregation (i.e., meta-ethnography or meta-synthesis) of qualitative studies remains relatively rare and controversial. We have attempted this procedure within an investigation of patient priorities and evaluations of primary care in order to triangulate an instrument development process as well as explore associated dilemmas.

METHODS

The procedures included a literature search of qualitative research on patient priorities and evaluations and creation of a framework for quality assessment of retrieved papers. The tool for the evaluation of quality in qualitative studies was piloted, refined, and applied to the retrieved literature. The articles were equally distributed between two teams in random fashion, and inter-rater agreement calculated. Finally, we formulated and applied a strategy for aggregation of data from included papers that allowed comparison to a systematic review of quantitative studies on the topic.

RESULTS

Thirty-seven articles met inclusion criteria. Twenty-four of these articles were of sufficient quality to be included in the qualitative aggregation. Inter-rater agreement ranged from 0.22 to 0.77 and 0.38 to 0.60 for pair and assessor comparisons, respectively. The aggregation strategy enabled synthesis within sub-categories of the heterogeneous papers.

CONCLUSIONS

We have devised a modestly reliable instrument to assess the quality of qualitative work. The procedure for quality assessment and aggregation appears to be both feasible and potentially useful, though both theoretical and practical problems underline the need for further refinement prior to widespread utilization of this approach.

PRACTICE IMPLICATIONS

An instrument to assess the quality of qualitative work within the context of aggregation efforts is described. Calculating inter-rater reliability in this framework can support future quality assessments. A method of breaking a heterogeneous collection of included papers into sub-categories to enable aggregation of qualitative studies is applied and demonstrates its feasibility and potential usefulness.

Eating attitudes among adolescents

BACKGROUND

Israeli youth lead 27 western countries in dieting. The prevalence of eating disorders has been rising in the last 30 years, causing social problems and medical complications.

OBJECTIVES

To examine the prevalence of eating disorders among high school students in a region in northern Israel (Misgav) and to examine the relationship between the parents' employment status and the subject's eating disorder.

METHODS

A structured questionnaire was administered to collect demographic data. The short version of the Eating Attitudes Test (EAT-26) was used to evaluate the subject's attitudes toward and preoccupation with food, dieting, eating, physical appearance, and personal control over eating.

RESULTS

Of 360 students approached, 283 (78%) completed the self-report EAT-26. One of every 5 females and one in every 20 males had an abnormal eating attitude. The rate of pathologic EAT-26 results, 20.8%, falls within the high range of similar community-based samples of female adolescents. There were no differences in EAT-26 score between students with an employed or unemployed mother; however, there was a trend for higher EAT-26 scores among those whose father was unemployed (21.4% vs. 12.7%, chi2 = 0.14).

CONCLUSIONS

The findings support our hypothesis of a relatively high rate of abnormal eating attitudes (as reflected by high EAT-26 score) in this population. Another possible risk factor is having an unemployed father, which warrants further research and attention. Our next step is to introduce an intervention program in the school and to study its effect.

[Complementary medicine research in Israel between the years 1994-2004]

Alternative and complementary medicine (CAM) is gaining the attention of the medical academic community due to increased public use and ongoing concern of efficacy, safety and quality of CAM treatments. The aim of this work was to review the scope of research that was performed in Israel during the past 10 years. We detected 91 works that focus on clinical research: RCT's, pilot studies, comparative studies, surveys of prevalence & patterns of use, and the attitudes of the medical establishment and of medical students. The results of this work indicate considerable progress in the research of CAM within medical establishments in Israel. We believe that future research will benefit from an upgrading of quality of research that will further focus on cost-effectiveness as well as on possible adverse effects of CAM. This goal can be achieved through appropriate research training of MD's and CAM therapists, and by governmental funding of the research.

An approach to teaching primary care physicians how to integrate complementary medicine into their daily practices: a pilot study

This paper describes a pilot educational approach to integration of complementary and alternative medicine (CAM) into the daily routine of primary care practice. Twelve (12) family practice residents and specialists were assigned to develop an integrative treatment program geared to address the needs of their own patients. In the process, participants were asked to formulate treatment plans by searching resources to find appropriate CAM modalities and consult with CAM practitioners. The effectiveness of the educational process was assessed by questionnaires. The researchers found that providing a short course in advanced integrative medicine improves physician ability to better formulate an individualized treatment plan. This approach of teaching has long-standing results, as noted with a 2-year follow-up evaluation.

[Recording of risk factors and preventive pharmaceutical therapy among ischemic heart disease patients in family practice during the years 1993-1998]

The review of international literature yielded unsatisfactory performance of guidelines for secondary prevention of cardiovascular diseases. This study aimed to evaluate records of the implementation of guidelines published in 1995, for the treatment and follow-up of patients after myocardial infarction in family medicine. In a retrospective sectional cohort study we identified all the patients with previous myocardial infarction in the practices of 6 family physicians, with an overall total of 97 patients. All data was gathered from manual medical records. The quality of care was evaluated according to follow-up indicators such as performance of blood pressure measurement, LDL cholesterol tests and according to secondary prevention indicators such as: treatment with aspirin, beta blockers and statins. In the cohort of 97 patients, 20.6% had diabetes, 53.6% had hypertension and 88.7% performed blood pressure follow-up, 100% cholesterol and fasting glucose tests, and 86.6% LDL cholesterol tests. Of the eligible patients, 98% received aspirin, 81% received beta-blockers and 76.2% were treated with statins. The target LDL cholesterol was not achieved by 66.7% of the patients. During the years 1993-1998 the quality of secondary prevention in the study was better than findings reported in international publications in corresponding years. However, the treatment of hypercholesterolemia should be improved.

[A review of the evidence based smoking cessation interventions delivered by the family physician]

Smoking is one of the most preventable causes of morbidity and mortality resulting in almost 10,000 deaths each year in Israel. Since tobacco-related disease is preventable, efforts to promote cessation in patients who smoke should be a routine step in preventive primary care measures. In Israel, 26% of the adult population smoke. Within this group, a third want to quit but only two percent succeed in abstaining from smoking for a whole year. Family physicians are in an ideal position to facilitate patients' attempts to quit smoking: 70% of smoking patients report that firm, supportive messages from their family physician can act as an important motivating factor to quit smoking. The updated Clinical Practice Guidelines from the US Public Health Service recommend that family physicians should opportunistically advise smokers to stop smoking during routine consultation, encourage and assist smokers in the use of nicotine replacement therapies or bupropion and refer smokers to professional behavioral or psychological counselors specializing in smoking cessation. Most physicians rank smoking as the most important behavior affecting health, but few physicians are confident in their own ability to help their patients stop smoking. In this review the authors present several evidence-based strategies that were found to be helpful in promoting smoking cessation when delivered by general practitioners. The power of the physician's advice, first and second line agents, behavioral counseling and stage based interventions, are all discussed in detail.

Is a biopsychosocial-spiritual approach relevant to cancer treatment? A study of patients and oncology staff members on issues of complementary medicine and spirituality

BACKGROUND

Complementary and alternative medicine (CAM) is increasingly being used by patients with cancer.

OBJECTIVES

Our aim is to compare the attitudes of cancer patients who use CAM to those of nonusers, on issues of CAM, biopsychosocial considerations, and spiritual needs.

METHODS

Questionnaires were administered to patients and medical care providers in a tertiary teaching hospital with a comprehensive cancer center.

RESULTS

Forty-nine percent of the study patients reported integrating CAM into their conventional care. Health care providers considered psychological and spiritual needs as major reasons for CAM use, while patients considered the familial-social aspect to be more important.

CONCLUSIONS

Cancer patients do not correlate CAM use with spiritual concerns but expect their physicians to attend to spiritual themes. Health care providers involved in oncology cancer care should emphasize spiritual as well as CAM themes. The integration of these themes into a biopsychosocial-spiritual approach may enrich the dialogue between patients and health providers.

The role of the patient care team in elderly people decision on influenza vaccination

Understanding the elderly decision-making process on influenza vaccination is important in developing appropriate strategies to increase uptake. Our objective was to explore the decision making process on influenza vaccination among an elderly population. Prospective documentation of baseline data and vaccination status of elderly primary care patients was followed by a telephone survey 5 months later to explore their decision making process. Baseline data and vaccination status were documented on 1313 patients out of whom 51% received the influenza vaccine. Telephone survey was attempted in all of them and eventually 950 (72.4%) were interviewed. When members of the patient care team (PCT) provided information on the vaccine, were consulted about it and were actively involved in the vaccination decision, each resulted in a significantly higher (p<0.0001) rate of immunization. After logistic regression analysis, only consultation with PCT remained significantly associated with higher (p<0.0001) immunization rate. Our findings emphasize the central role of the PCT in improving uptake of the influenza vaccine and point at the stages where change can, and should, be made.

An approach to educating family practice residents and family physicians about complementary and alternative medicine

Complementary and alternative medicine (CAM) in the context of medical education is a controversial topic among the medical community. With the increased popularity of complementary and alternative medicine, medical educators are faced with the need of educating physicians so they would become competent to communicate with patients about CAM. As academic medicine shows more interest in CAM, it is critical to develop initiatives to overcome physicians' attitudinal barriers toward CAM and develop an instruction strategy that can address these needs. An approach to educate family practice residents and family physicians about CAM is described in this article. This patient-centered teaching approach hinges on the belief that CAM and family medicine are closely related. It espouses utilizing critical thinking and basing decisions on evidence-based material. The course covered four main topics in CAM: herbal medicine, traditional Chinese medicine (TCM), homeopathy and complementary nutrition. The course had limited objectives of exposing physicians to the common methods in CAM and providing sufficient information, so physicians could provide their patients with an informed, safe and balanced advice. The instructions emphasized the importance of improving physician-patient relationship and enriching the participant both professionally and personally. Results of our study revealed that after the course physicians' referral to CAM became more selective, at the same time, their personal use of CAM also increased. This reflects the increased value of CAM in the physicians' own healthcare, as well as their improved knowledge of appropriate referral patterns. Most importantly, the course increased the physicians' awareness of the psychosocial aspect of clinical problems encountered in family practice and, through the close observation of CAM in practice, gave them an additional viewpoint to better understand the patient-doctor relationship.

Predicting self-reported health: the CORDIS study

BACKGROUND

There have been few attempts to determine factors important in predicting subsequent self-reported health (SRH) in population studies of men or women.

METHODS

In the following study, we determine the predictive value of behavioral and biomedical risk factors for self-evaluated health 7.7-11.5 years later in 2,962 male industrial workers.

RESULTS

We found that age [odds ratio (OR) per 10 years = 1.5, 95% confidence interval (CI) = 1.30,1.74], current smoking (OR = 1.63, 95% CI = 1.23,2.16), higher systolic blood pressure (SBP) measurements (OR = 1.16 per 10 mm Hg, 95% CI = 1.03,1.31), use of chronic medications (OR =2.75, 95% CI = 2.03,3.71), diabetes mellitus (OR = 2.83, 95% CI = 1.73-4.63), low educational status (OR = 1.67, 95% CI = 1.23, 2.25), and lack of regular leisure sports activity (OR = 1.67, 95% CI = 1.04, 2.17) significantly added to a logistic regression model predicting poorer self-evaluated health 7.7-11.5 years later ]area under the receiver-operator curve (ROC) = 76.0%]. There was a trend for poorer self-rated health in the obese workers (OR = 1.40, 95% CI = 0.97-2.01).

CONCLUSIONS

Behavioral and biomedical risk factors for mortality predict self-evaluated health 7.7-11.5 years later.

[Screening for depression in primary care clinics in Israel--how wide is the gap?]

Depressive disorders are common and cause substantial suffering, loss of productivity, and increased morbidity and mortality. Nonetheless, it is frequently cited that the disorder is under-diagnosed. In this article we examined the utility of a two phase case detection strategy for depression in primary care clinics in Israel. We compared screening findings with the medical charts diagnoses. A three-question screening test for depression taken from the Diagnostic Interview Schedule (DIS) was answered by 551 primary care patients. Those who answered positively on one or more questions were asked to answer a more specific and detailed questionnaire in order to detect depression: The Inventory to Diagnose Depression (IDD). The results were compared with the diagnoses on the medical charts, and treatment for depression. In addition the number of visits to the primary care physician was compared, between depressed and non-depressed patients. The first questionnaire (from the DIS) was completed by 551 patients. A total of 222 (40%) of these patients gave at least one positive answer. Only 113 (51%) agreed to answer the second questionnaire (IDD). According to the IDD, 15 were depressed: 9 fulfilled the criteria for major depression (1.6% of the 551) and 6 fulfilled the criteria for minor depression (1.1%). Of the 9 that the IDD identified as suffering from major depression only one was diagnosed as such according to his medical chart. Two of the patients that the IDD found to be suffering from minor depression were diagnosed according to their medical chart as depressive. Five patients that were diagnosed by their physicians as suffering from depression were not diagnosed by the IDD. In a sample of patients who answered positively to one or more questions of the DIS, but refused to answer the IDD, it was found that 10 (20% of the sample) were diagnosed as depressed and 32% of the sample had some psychiatric diagnosis according to their charts. We discovered that patients who suffer from a depressive disorder visited their physicians more often than those that were not depressed: 12.7 and 7.14 respectively (during 6 months) (p < 0.028).

IN SUMMARY

The combined two phase screening instrument was found to be impractical and problematic for use as a screening tool. There was a difference between the diagnoses that appeared in the charts and those resulting from the screening tool. Using the 3 questions from the DIS as a case finding tool for depression in high risk populations (such as frequent attenders) might prove useful in primary care setting.

[Oral anticoagulation treatment--control, risks, benefits, and informed consent]

The most common indications for warfarin therapy are atrial fibrillation, the presence of a mechanical heart valve and venous thromboembolism. The risks and benefits of treatment for these conditions have been fairly well characterized and recent consensus groups have provided guidelines which are nearly identical. Although we can define the recommended range of the PT in INR units, it is often difficult under the best of circumstances to keep the INR in the desired range. Physicians often dont recognize the limitations of INR testing. Furthermore, the continued risk of thromboembolic and bleeding complications despite state of the art treatment might not be recognized by the patient. This places the physician at risk of a malpractice suit and emphasizes the need for informed consent. The following review will summarize current recommendations for the major conditions requiring long-term management with oral anticoagulants, identify problems with PT-INR testing, consider when the laboratory should contact the physician urgently, define acceptable control of the PT-INR during audits, and finally suggest information for the patient, which might be used in an informed consent form.

[The psychological (long-term) sequelae of abortion]

This article aims to review the available literature on the short and long-term psychological sequelae of abortion. This subject remains controversial. The most common reactions women experienced after pregnancy loss were grief, depression and anxiety. From the reviewed literature it seems that those reactions are more common following spontaneous abortion than after therapeutic abortion. Risk factors for these reactions include past psychiatric history, social and cultural attitude, poor social support, history of previous therapeutic abortion, the fact that the current abortion is the result of medical or genetic problem, no living children, or being a single woman. Most of the reviewed papers deal with short-term reactions and raise the need for long term research (more than 2 years). Only one such paper was found. It is recommended that all those who treat women that had an abortion should be aware of its psychological consequences and help identify and refer high-risk women for treatment.

Advances in the field of low back pain in primary care: a report from the fourth international forum

STUDY DESIGN

Review of advances in the primary care research on low back pain (LBP) from a unique international forum, and analysis of open-ended questionnaires from participants.

SUMMARY OF BACKGROUND DATA

LBP continues to be one of the most common and challenging problems in primary care. It is associated with enormous costs in terms of direct health care expenditures, and indirect work and disability-related losses.

OBJECTIVE

To ascertain the current status and state of the art regarding LBP in primary care.

METHODS

Four reviewers independently assessed the content and implications of presentations at the Fourth International Forum for Primary Care Research on LBP, pooled the data, and then augmented it with open-ended questionnaires completed by 35 participants.

RESULTS

The Fourth Forum documented the field's emergent new paradigm-a transition from thinking about back pain as a biomedical "injury" to viewing LBP as a multifactorial biopsychosocial pain syndrome. The paradigm shift has occurred in the context of increased interest in evidence-based medicine regarding LBP in primary care. The Forum demonstrated the strides taken in moving from research and evidence gathering, through guidelines and policy formulations and finally to the dissemination and implementation imperative. There was an increasing confidence among the Forum researchers that LBP can be managed successfully in primary care settings through a combination of encouraging activity, reassurance, short-term symptom control, and alteration of inappropriate beliefs about the correlations of back pain with impairment and disability. There is also recognition that a wide range of international, evidence-based guidelines now exists that have very similar messages.

CONCLUSIONS

The Fourth Forum reflected a major shift in the conceptualization of LBP in primary care and an increased emphasis on implementation and dissemination of LBP research findings and clinical guidelines. Although there is a wide array of challenges ahead, the Fourth Forum provided a clear message regarding the need to focus research energies on changing practitioner behavior.

Effects of homeopathic intervention on medication consumption in atopic and allergic disorders

CONTEXT

Allergies are the most common immunologic diseases among the general population. Increasing evidence suggests that the incidence of allergic disorders is rising dramatically. Conventional medicine provides only limited relief and does not offer a complete cure to this health problem. Consequently, patients seek additional approaches and therapies to integrate into their healthcare. Homeopathy is one of the leading complementary modalities used to treat this health problem.

OBJECTIVE

This preliminary study assessed the effect of integrating homeopathic treatment in allergic diseases on conventional medication consumption in a health maintenance organization.

DESIGN

Retrospective outcome study designed as a before-after trial.

SETTING

Patients were studied in a complementary medicine clinic affiliated with an Israeli health maintenance organization.

PARTICIPANTS

Forty-eight patients were treated for allergic diseases with homeopathic remedies and conventional medications.

MAIN OUTCOME MEASURES

A computerized medication chart for each patient was evaluated for conventional medication consumption 3 months before and 3 months after the homeopathic intervention. Each patient served as his or her own control.

RESULTS

Fifty-six percent of patients in this study reduced their use of conventional medication following the homeopathic intervention. Patients who used conventional medications for their allergic disorders reduced their medication expense by an average of 60%, with an average savings of $24 per patient in the 3-month period following the homeopathic intervention.

CONCLUSIONS

This retrospective outcome study demonstrates cost savings for an Israeli health maintenance organization. The homeopathic intervention led to a modest but significant reduction in the use of medications commonly used to treat allergic conditions and their complications. Larger controlled studies are needed to verify these findings.

Determining teaching objectives for the family medicine clerkship in medical school--an Israeli national Delphi survey

BACKGROUND

Most of the published documents proposing teaching objectives for undergraduate clerkships were prepared by expert bodies. Seldom have the clinical teachers, who are critical to the learning process and to the implementation of the teaching objectives, been the actual proponents of its core content.

OBJECTIVE

To develop a national-scale proposal of teaching objectives for the family medicine clerkship in medical school, using a consensus method and the actual, community-based teachers as the expert body.

METHODS

The Delphi method was chosen for that purpose. In the first round all 189 family medicine teachers in Israeli medical schools were asked to propose five teaching objectives. In the second round the objectives, which were generated in the first round, were characterized by key words and were sent to the participants as a second round for ranking according to their importance.

RESULTS

A total of 116 family medicine teachers (61.38%) responded in the first round and 91 of the 116 (78.5%) in the second round. They formulated 51 teaching objectives listed in order of importance, covering a wide array of themes and including knowledge, attitude and skills objectives. The most important objectives were common problems in primary care, recognition of the biopsychosocial model, and understanding the importance of the doctor-patient relationship. The structure of the list provides a unique insight into the relative importance of each objective in the context of the whole core content of the clerkship.

CONCLUSIONS

Constructing a proposal for teaching objectives is feasible using the Delphi method and the field instructors as the selecting body. The process and its results can provide faculty with relevant and important suggestions on the content and structure of the family medicine clerkship.

Trends in medical specialty choice among Israeli medical graduates, 1980-1995

BACKGROUND

Which medical specialties do Israeli medical graduates choose? Answers to this question can serve as an essential means of evaluating both Israeli medical education and the healthcare system.

OBJECTIVES

To determine the distribution of medical specialty choice, its change over time and the possible influence of the medical school on the choice; to study the graduates' gender, gender variability in specialty choice and time trends in both; and to assess the choice of family medicine as a career among the graduates as a group, by medical school, gender, and time trends.

METHODS

The study population comprised all graduates of the four medical schools in Israel during 16 years: 1980-1995 inclusive. Data were obtained from the four medical schools, the Israel Medical Association's Scientific Council, and the Ministry of Health. Data allowed for correct identification of two-thirds of the graduates.

RESULTS

A total of 4,578 physicians graduated during this period. There was a significant growth trend in the proportion of women graduates from 22.6% in 1980 (lowest: 20.0% in 1981) to 35.3 in 1995 (highest: 41.5% in 1991). Overall, 3,063 physicians (66.8%) started residency and 1,714 (37.4%) became specialists. The four most popular residencies were internal medicine, pediatrics, obstetrics and gynecology, and family medicine. Ten percent of Israeli graduates choose family medicine.

CONCLUSIONS

The overall class size in Israel was stable at a time of considerable population change. Women's place in Israeli medicine is undergoing significant change. Family medicine is one of the four most popular residencies. A monitoring system for MSC in Israel is imperative.

Doctor-patient discussions of alternative medicine for back pain

OBJECTIVE

To document the frequency of conversations about alternative medicine during primary care consultations for back pain in diverse settings.

DESIGN

"Exit interview" type patient survey.

SETTINGS

General practices in Seattle, Washington; rural Israel; and Birmingham, England.

PATIENTS

A convenience sample of 218 adults completing a doctor visit for back pain.

MAIN OUTCOME MEASURES

Frequencies of doctor-patient discussions of alternative medicine.

RESULTS

Alternative medicine was discussed in a minority of visits (US site 40%, Israel site 37%, UK site 14%, p < 0.05). At each site, patients initiated at least half of the discussions. Users were five to six times more likely to discuss alternative medicine with their doctor than non-users (p < 0.05 for comparison at each site). The percentage of patients who used alternative medicine but left the consultation without discussing it was similar at all sites (US site 17%, Israel site 23%, UK site 15%).

CONCLUSIONS

Discussions of alternative medicine occurred in a minority of consultations for back pain although the rate varied considerably by site. Discussions were initiated primarily by patients who use it.

[The efficacy of a doctor-patient appointment in a primary care setting dedicated to preventive medicine]

BACKGROUND

Previous data on the importance of promoting cessation of smoking, physical activity and a healthy diet exists in the literature. However, there is insufficient evidence that counseling healthy patients to change their life-styles will indeed have a positive effect on their behavior. In this study we examined whether a single doctor-patient appointment dedicated to preventive medicine can have a positive effect on cessation of smoking, promoting physical activity and weight control.

METHOD

Eighty-eight patients from the "French Carmel" Clinic, aged 25-50, were summoned to a doctor-patient appointment lasting 20 minutes. The patients filled out a questionnaire and their weight and height were measured. The doctor counseled the patients to cease smoking, increase their physical activity and lose weight. The counseling was patient-oriented. Six to twelve months later the patients were interviewed by telephone and data was collected. The data was processed on a windows-based SPSS program.

RESULTS

Of the 25 smoking patients, 2 (8%) stopped smoking, another 5 (20%) reduced their cigarette smoking. None of the non-smokers began smoking during the study, and there was no increase in the number of cigarettes smoked among the smokers. There was an increase in the number of patients who engaged in physical activity on a regular basis after the intervention: 56.1% as compared to 42.7% prior to the consultation. This increase was found to be statistically significant (p < 0.001). Among overweight (BMI 25-26.9) and obese (BMI > 27) patients there was a decrease in BMI following the intervention which was found to be statistically significant (p < 0.01). Among patients with normal weight (BMI 20-24.9) and underweight (BMI < 20) there was a decrease in BMI which was not statistically significant.

CONCLUSION

In an era when economic considerations challenge the everyday work of the physician, we have showed in our study that a 20-minute doctor-patient appointment could influence the patient's life-style and thus promote healthy living.

Doctor-patient concordance and patient initiative during episodes of low back pain

Doctor-patient concordance and patient initiative were examined in a prospective network interview study, with telephone follow-up, of a cohort of 100 patients presenting with low back pain to their family physician. The average overall rate of concordance was 60% (95% CI = 53 to 66), with the highest rates for radiographic imaging studies and sick leave. No correlation was found between concordance and patient parameters. Subjects initiated an average of two (95% CI = 1.7 to 2.3) diagnostic or therapeutic procedures, the most common of which were for medications (40%), followed by bed rest (26%) and back school (22%). One out of every six subjects initiated a referral to a complementary therapist. Positive correlation was found between patient initiatives and pain severity (P = 0.022) and disability (P = 0.02). There was a negative correlation between the subjects' initiatives and their belief that the physician understood the cause of their pain and its influence on their life (P = 0.02). Overall, those patients who described more pain or disability sought more types of diagnostic and therapeutic measures, while those who felt they had been understood sought less.

Chlamydia preumoniae in ischemic heart disease

BACKGROUND

Previous work has suggested an association between Chlamydia pneumoniae infection and coronary artery disease. The infection was demonstrated by titers of antibodies--enzyme-linked immunosorbent assay or immunofluorescence, and polymerase chain reaction--and by the findings of C. pneumoniae in the atherosclerotic plaque.

OBJECTIVES

To evaluate the association between chronic infection with C. pneumoniae, as measured by a high titer of IgG antibody, and CAD. Our study was designed to explore the relationship between seropositivity to C. pneumoniae and serious coronary events, and to assess whether or not there may be an additional association between established cardiovascular factors and infection with this organism.

METHODS

The serum of 130 patients with proven CAD was tested for the presence of IgG antibodies to C. pneumoniae using an ELISA test. A titer < or = 1:64 using the microinfluorescence method, the recognized "gold standard," correlates with a positive result when using the ELISA method. The mean age was 57 (40-65 years). The patients, 82% male and 18% female, had either myocardial infarction (n = 109) or unstable angina (n = 21) 6 months before the investigation (range 3-24 months). The serum for the control group was obtained from 98 blood donors from the same area matched for age 52 (40-58 years) and sex. The donors had no known cardiac history.

RESULTS

In the CAD group 75% of patients were positive for C. pneumoniae compared to 33% in the control group (P = 0.001). No increased correlation could be demonstrated between traditional risk factors and C. pneumoniae infection, except in those patients with diabetes mellitus. We found a lower prevalence of IgG antibody to C. pneumoniae in the diabetes subgroup than in other subgroups (P < 0.006), but a higher prevalence than in the control group.

CONCLUSIONS

We demonstrated a more than twofold increase in seropositivity to C. pneumoniae among patients suffering serious coronary events, and this trend was independent of gender, age or ethnic group. These findings suggest that chronic C. pneumoniae infection may be a significant risk factor for the development of CAD, but this correlation should be investigated further.
