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.

Exceptional patients and communication in cancer care-are we missing another survival factor?

OBJECTIVE: There is increased awareness of the issue of exceptional survival beyond expectations among cancer patients with poor prognosis, and researchers are starting to look closely at this phenomenon. In this study, we explored the perceptions of these "exceptional patients" as to their understanding and insight into their unusual experience. METHODS: We used a qualitative approach consisting of in-depth, open-ended interviews with exceptional patients in two locations, Texas and Israel, from 2007 to 2014. The interviews were audio-recorded and qualitatively analyzed, and gave rise to illness narratives entailing detailed descriptions of patients experience over the course of their disease and treatment. A qualitative content analysis focusing on contextual meaning was utilized. RESULTS: Twenty-nine patients participated in our study. The mean years since diagnosis was 9.55 years (range, 4-23 years). All patients had received conventional treatment, including surgery, chemotherapy, and radiation therapy. One of the prevailing themes in these interviews was related to the patient-doctor relationship. Most participants mentioned that the support they received from one or more physicians was a crucial factor for their exceptional survival. CONCLUSION: The significance of patient-doctor relationship in cancer survival requires further research. This research is especially important as it adds to the current trend of patient centered care and points to the added value of relationship between health providers and patients. This relationship, as perceived by these exceptional patients, can be a factor that adds to improved survival in cancer care.

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.

Breastfeeding motivation and Self-Determination Theory.

RATIONALE: In the current social climate, breastfeeding is regarded as the "gold standard" of babies' nutrition and optimal mothering. It is not surprising, therefore, that the vast majority of contemporary women begin breastfeeding after they give birth. OBJECTIVE: This paper presents two separate quantitative studies conducted in Israel which examined breastfeeding motivation and its association with maternal well-being as derived from Self-Determination Theory (SDT). In Study I, a new breastfeeding motivation scale reflecting the various SDT-informed motivations was developed. Study II sought to validate the structure of the scale and to examine the hypotheses derived from SDT. METHODS: In Study I, which took place in 2007, 130 mothers of at least one child under the age of eight years old filled out the Breastfeeding Motivation Scale. In Study II, which took place during the years 2008-2010, a different sample of 236 women were followed at three different time points: during the third trimester of pregnancy, at eight weeks postnatal, and at five months postnatal. The participants completed the Breastfeeding Motivation Scale and maternal well-being, maternal self-efficacy and maternal attachment questionnaires. RESULTS: The findings supported the structure of the Breastfeeding Motivation Scale according to SDT. As predicted, autonomous motivation was positively correlated with maternal well-being and self-efficacy, while controlled motivations were positively associated with distress and inversely correlated with self-efficacy. Anxious attachment predicted both controlled and autonomous breastfeeding motivations. DISCUSSION: The findings support the validity of the SDT for breastfeeding motivations, and highlight the role of these motivations as differentiating between positive and negative subjective well-being, among breastfeeding women.

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.

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.

Comparison of mortality in patients with coronary or peripheral artery disease following the first vascular intervention.

OBJECTIVES: Patients with peripheral artery disease (PAD) less frequently achieve secondary prevention goals compared with patients with coronary artery disease (CAD). We aimed to compare mortality rates in patients with PAD and CAD following first vascular intervention. PATIENTS AND METHODS: Patients 18 years of age or older without a history of cardiovascular disease, who underwent first coronary or lower limb vascular intervention between 2002 and 2010, were included in this study. The primary endpoint was all-cause mortality. RESULTS: Of the 9950 participants, 8242 (82.8%) underwent first coronary revascularization and 1708 (17.2%) received first peripheral vascular intervention. During a mean follow-up period of 5.6±2.3 years, 1283 (12.9%) participants died. Compared with CAD patients, patients with PAD had significantly worse long-term prognosis with an increased risk for all-cause mortality (hazard ratio=2.95, 95% confidence interval 2.6-3.3, P<0.0001). This association remained statistically significant following a multivariable analysis (hazard ratio=1.86, 95% confidence interval 1.6-2.1, P<0.0001). Furthermore, PAD patients were less frequently treated with cardioprotective medications including statins, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, aspirin, and clopidogrel (P<0.001). CONCLUSION: Patients with PAD have worse outcome compared with patients with CAD, even in the specific group of patients following first vascular intervention. These findings demand more effort to improve secondary prevention guidelines in all patients with cardiovascular diseases, but especially in PAD patients.

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.

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.

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.

Mortality and coronary heart disease in euthyroid patients.

BACKGROUND: Subclinical thyroid dysfunction is associated with increased mortality and cardiovascular risk. It is unknown whether this association remains within normal thyroid function range. METHODS: The study was conducted using the computerized database of the Sharon-Shomron district of Clalit Health services. Included were subjects aged ≥40 years with normal thyroid function. Patients with a history of thyroid or cardiovascular diseases or diabetes were excluded. The primary end points were all-cause mortality and the need for coronary revascularization with either percutaneous coronary intervention or coronary artery bypass grafting. RESULTS: The 42,149 participants were stratified into 3 groups of equal thyrotropin intervals (0.35-1.6, 1.7-2.9, and 3-4.2 mIU/L). During a mean follow-up of 4.5±2.1 years, 4239 (10.1%) participants died and 1575 (3.7%) underwent coronary revascularization. For both women and men, the lowest mortality rates were observed in the intermediate thyrotropin group. Nevertheless, only for the low thyrotropin group, mortality risk remained significantly higher as compared with the intermediate thyrotropin group, even following multivariate model adjusted for the conventional cardiovascular risk factors, in both women (odds ratio 1.22; 95% confidence interval, 1.09-1.36 for the low thyrotropin group, compared with the intermediate group) and men (odds ratio 1.14; 95% confidence interval, 1.01-1.3 for the low thyrotropin group, compared with the intermediate group). There was no significant difference in the need for coronary revascularization among the 3 thyrotropin groups in both men and women. CONCLUSIONS: Low thyrotropin level within the reference range is associated with increased risk for all-cause mortality.

HDL-C levels and revascularization procedures in coronary heart disease patients treated with statins to target LDL-C levels.

BACKGROUND: A low level of high-density lipoprotein cholesterol (HDL-C) is a strong predictor for cardiovascular disease morbidity and mortality at all low-density lipoprotein cholesterol (LDL-C) concentrations. HYPOTHESIS: We evaluated this association in routine clinical practice among statin-treated coronary heart disease patients who achieved LDL-C target levels. This association also exists in routine clinical practice. METHODS: A retrospective dynamic cohort included all male coronary heart disease patients of the Sharon-Shomron district, Clalit Health Services, Israel, with LDL-C levels < 100 mg/dL and who were receiving statins (≥ 6 purchases/y) from January 1998 to June 2008. Data were collected on demographic variables; coexistence of hypertension, diabetes mellitus, and peripheral vascular diseases; details of revascularization procedures; and lipid levels. The outcome variable was revascularization procedure, by either percutaneous intervention or coronary artery bypass graft. RESULTS: The study group of 909 male patients was stratified into quintiles, based on mean HDL-C levels: Q1 (n = 179): ≤ 26.4 mg/dL; Q2 (n = 190): 26.4-≤ 30.0 mg/dL; Q3 (n = 191): > 30.0-≤ 34.0 mg/dL; Q4 (n = 186): > 34.0-≤ 41.0 mg/dL; Q5 (n = 163): > 41.0 mg/dL. During the study period, 307 (33.8%) of the cohort required ≥ 1 revascularization procedure. Those in the highest quintile underwent significantly fewer procedures (40.8% for Q1 vs 16.6% for Q5, P<0.001). This significant effect of the highest HDL-C quintile was not influenced by any variable. CONCLUSIONS: The protective effect of high HDL-C levels, regardless of other risk factors, in preventing revascularization procedures was confirmed in the routine clinical practice among statin-treated CHD patients who reached LDL-C level < 100 mg/dL. Possible additional benefits of using agents to raise HDL-C levels should be investigated.

Cardiovascular risk in patients with fasting blood glucose levels within normal range.

Fasting glucose levels elevated beyond the normal range have been associated with increased cardiovascular risk. However, it is unknown whether this association exists for variations of fasting glucose within the normal range. The present study was conducted using the computerized database of the Sharon-Shomron District of Clalit Health Services. Included in the present study were subjects with fasting glucose levels within the normal range (< 100 mg/dl). We excluded patients with a history of cardiovascular disease or diabetes. The primary outcome was the incidence of coronary revascularization with either percutaneous coronary intervention or coronary artery bypass grafting. The 28,263 participants (age 53.7 ± 12.2 years) were divided into quartiles according to the fasting glucose level (75.4 ± 4.5, 83.6 ± 1.7, 88.9 ± 1.4, and 95.1 ± 2.2 mg/dl). During a mean follow-up of 5.9 ± 0.7 years, 424 subjects required coronary revascularization. A progressive increase was seen in the risk of coronary revascularization as the fasting glucose levels increased within the normal range (hazard ratio 1.73, 95% confidence interval 1.3 to 2.3, p > 0.001, between the fourth and first quartiles). However, this association lost its statistical significance after adjustments for the conventional coronary risk factors (hazard ratio 1.17, 95% confidence interval 0.85 to 1.62, p = 0.328). In conclusion, elevated fasting glucose levels within the normal range were associated with an increased cardiovascular risk. This association was caused by the greater prevalence of the other conventional risk factors and not by the glucose level itself.

[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.

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.

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.
