Specialized Pain Clinics in Primary Care: Common Diagnoses, Referral Patterns and Clinical Outcomes - Novel Pain Management Model.

An estimated 19% of the adult population in western countries lives with chronic pain. Pain management lies mainly within the primary care and community setting. We evaluated the outcome of a new model of secondary care clinics, conducted by primary care physicians with specialized training in pain medicine. Data on referral patterns, prevalence of pain diagnosis, and medication consumption were recorded at five secondary pain management clinics in the community setting. In total, 997 patients with pain attended 2,652 visits (average 2.7 visits per patient) during 12 mo. Patients' age ranged from 18 to 92 yr (mean 59 ± 19). Mean pain intensity on the first visit, evaluated by the visual analogue scale was 7.7/10. Myofascial pain syndrome was the most common diagnosis (82%). Treatment included dry needling or trigger point injection (82%), manual myofascial release (23%), and pharmacotherapy (38%). Significant short-term improvement after treatment was reported by 75% of patients, and 72% reported long-term improvement. Four percent were referred to tertiary care pain clinics, 5% were referred to other specialists, and 5% to imaging. Secondary, community-based pain clinics, run by specially-trained primary physicians, demonstrated feasibility. The vast majority of patients referred to the clinics were treated using simple, inexpensive modalities, while sparing referrals to unnecessary consultation visits, imaging tests, and medications.

Vitamin B12 screening in metformin-treated diabetics in primary care: were elderly patients less likely to be tested?

Low serum B12 level is a common occurrence in patients with type 2 diabetes (T2DM) treated with metformin. There is lack of evidence concerning blood testing of vitamin B12 and current clinical guidelines make no recommendations on the detection or prevention of vitamin B-12 deficiency during metformin treatment. Our objective was to examine the current practice and clinical determinants of vitamin B12 testing in metformin treated T2DM patients. Data were collected from health maintenance organization patients, and consisted of T2DM patients who were newly prescribed metformin from 2008 to 2013. Patients were randomly divided into two subgroups: referred for a vitamin B12 blood test, and did not receive a referral. The demographic data and medical characteristics were analyzed. 5131 patients began taking metformin during the study period. Of these 2332 (44.5 %) had vitamin B12 tested. Significant differences were found between the groups in regard to glycosylated hemoglobin, low density lipoprotein, systolic blood pressure, dyslipidemia, chronic renal failure, and disease duration. A significant positive association (p < .05) was found between vitamin B12 testing and insulin treatment, retinopathy, neuropathy and hypertension. Vitamin B12 in elderly (>75 years) patients was significantly lower (p < .01). Insulin treatment, hypertension, and chronic diabetic complications in metformin treated T2DM patients are associated with higher rates of vitamin B12 testing. T2DM patients 75 years and above were less likely to be tested for B12 deficiency.

Using weight-for-age percentiles to screen for overweight and obese children and adolescents.

There are relatively low rates of screening for overweight and obesity among children and adolescents in primary care. A simplified method for such screening is needed. The study objective was to examine if weight-for-age percentiles are sufficiently sensitive in identifying overweight and obesity in children and adolescents. We used data from two distinct sources: four consecutive cycles of the National Health and Nutrition Examination Surveys (NHANES) from the years 2005 to 2012, using participants aged 2-17.9 years for whom data on age, sex, weight, and height were available (n=12,884), and primary care clinic measurements (n=15,152). Primary outcomes were the threshold values of weight-for-age percentiles which best discriminated between normal weight, overweight, and obesity status. Receiver operating characteristic analyses demonstrated that weight-for-age percentiles well discriminated between normal weight and overweight and between non-obese and obese individuals (area under curve=0.956 and 0.977, respectively, both p<0.001). Following Classification and Regression Trees analysis, the 90th and 75th weight-for-age percentiles were chosen as appropriate cutoffs for obesity and overweight, respectively. These cutoffs had high sensitivity and negative predictive value in identifying obese participants (94.3% and 98.6%, respectively, for the 90th percentile) and in identifying overweight participants (93.2% and 95.9%, respectively, for the 75th percentile). The sensitivities and specificities were nearly identical across race and sex, and in the validation data from NHANES 2011 to 2012 and primary care. We conclude that weight-for-age percentiles can discriminate between normal weight, overweight and obese children, and adolescents. The 75th and 90th weight-for-age percentiles correspond well with the BMI cutoffs for pediatric overweight and obesity, respectively.

Managing Diabetes Mellitus: A Survey of Attitudes and Practices Among Family Physicians.

Due to the increasing prevalence of diabetes and the shortage of endocrinologists, family physicians have an important role in diabetes management. The purpose of this study was to examine the sources of knowledge, attitudes and practices of family physicians regarding the management of type 2 diabetes. Attendees at continuous medical education (CME) programs in Israel were requested to respond anonymously to written questions about their sources of knowledge about diabetes, the methods of diabetes management they advise their patients, their knowledge of diabetes medication treatments, and their attitudes toward people with type 2 diabetes. Questionnaires were completed by 362 family physicians (79% response rate). Of them, 329 (91%) reported that they usually manage their patients' diabetes care, including that of patients with concomitant risk factors. Their most common recommendations for diabetes control were: to increase physical activity, decrease total calorie intake, consult with a dietitian and undergo weight loss counseling. Almost all physicians (97%) reported providing lifestyle change counseling. Sixty percent reported lacking knowledge about nutritional issues. Only 58% answered correctly regarding the effect of the anti-diabetic drug, GLP1 analog. Board certified family physicians and their residents exhibited more knowledge about diabetes practice than did non-board certified family physicians. The great majority of family physicians surveyed usually manage their patients' diabetes themselves, and do not refer them to diabetes specialists. The implementation of strategies that will enhance the competencies and confidence of family physicians in diabetes management are important for achieving successful treatment.

Medical cannabis treatment for chronic pain: Outcomes and prediction of response.

BACKGROUND: Although studied in a few randomized controlled trials, the efficacy of medical cannabis (MC) for chronic pain remains controversial. Using an alternative approach, this multicentre, questionnaire-based prospective cohort was aimed to assess the long-term effects of MC on chronic pain of various aetiologies and to identify predictors for MC treatment success. METHODS: Patients with chronic pain, licensed to use MC in Israel, reported weekly average pain intensity (primary outcome) and related symptoms before and at 1, 3, 6, 9 and 12 months following MC treatment initiation. A general linear model was used to assess outcomes and identify predictors for treatment success (≥30% reduction in pain intensity). RESULTS: A total of 1,045 patients completed the baseline questionnaires and initiated MC treatment, and 551 completed the 12-month follow-up. At 1 year, average pain intensity declined from baseline by 20% [-1.97 points (95%CI = -2.13 to -1.81; p < 0.001)]. All other parameters improved by 10%-30% (p < 0.001). A significant decrease of 42% [reduction of 27 mg; (95%CI = -34.89 to 18.56, p < 0.001)] from baseline in morphine equivalent daily dosage of opioids was also observed. Reported adverse effects were common but mostly non-serious. Presence of normal to long sleep duration, lower body mass index and lower depression score predicted relatively higher treatment success, whereas presence of neuropathic pain predicted the opposite. CONCLUSIONS: This prospective study provides further evidence for the effects of MC on chronic pain and related symptoms, demonstrating an overall mild-to-modest long-term improvement of the tested measures and identifying possible predictors for treatment success.

Poor glycemic control as a reason for referral of diabetes patients to specialists in Israel.

AIMS/INTRODUCTION: Family physicians face the dilemma of when to refer patients with diabetes to specialists. This study examined attitudes of family physicians to referring patients with poor glucose control to diabetes specialists. MATERIALS AND METHODS: At continuous medical education courses, family physicians were asked to respond anonymously, as to whether they generally manage the diabetes of their patients, and specifically those with poor glycemic control (HbA1c>9.0%). RESULTS: Of 470 respondents, 426 (90%) reported that they generally manage their patients' diabetes; 202 (43%) reported that they manage the diabetes of patients with HbA1c>9.0%. Board certification in family medicine and affiliation to a health maintenance organization, but not sex, age, years of professional experience, or the proportion of patients with diabetes at their clinics, were associated with referral practices. CONCLUSIONS: Family medicine residency and organizational support appear to promote treatment by family physicians of patients with poorly controlled diabetes in the primary care setting.

Antiatherosclerotic effects of licorice extract supplementation on hypercholesterolemic patients: decreased CIMT, reduced plasma lipid levels, and decreased blood pressure.

BACKGROUND: Ethanolic extract of licorice root has been shown to reduce low-density lipoprotein (LDL) oxidation in atherosclerotic mice and in both hypercholesterolemic and normal lipidemic humans. OBJECTIVE: This study examined the effect of licorice-root extract on carotid intima-media thickness (CIMT) in individuals with hypercholesterolemia. DESIGN: Individuals with hypercholesterolemia (total cholesterol ≥6.18 mmol/L [240 mg/dL]) and without significant stenosis were randomly allocated to two groups: an experimental group that consumed 0.2 g/day of ethanolic extract of licorice root for 12 months, and a control group that received a placebo. RESULTS: Of 110 eligible participants, 94 (41-80 years old) completed the study. A significant CIMT decrease from 0.92±0.25 mm to 0.84±0.21 mm was observed in the experimental group compared with an increase from 0.85±0.17 mm to 0.88±0.19 mm in the control group. Mean plasma total cholesterol levels and LDL cholesterol decreased, at the range baseline to 1 year, from 284±32 mg/dl to 262±25 mg/dl and from 183±8.5 mg/dl to 174±9.1 mg/dl, respectively, for the experimental group (p<0.001) and from 291±35 to 289±31 mg/dl and from 177.6±10.7 to 179.3±9.6 (p=0.08), respectively, for the control group. Mean high-density lipoprotein (HDL) did not change significantly in either group. In the experimental group, systolic blood pressure decreased from 138±12 mmHg to 125±13 mmHg after 1 year (p=0.01) and increased from 136±15 mmHg to 137±13 mmHg in the control group. Diastolic blood pressure decreased from 92±9 mmHg to 84±10 mmHg (p=0.01) in the experimental group and increased from 89±11 mmHg to 90±8 mmHg in the control group. CONCLUSION: Following 1 year of licorice consumption, mean CIMT, total cholesterol, LDL levels, and blood pressure were decreased. This suggests that licorice may attenuate the development of atherosclerosis and of related cardiovascular diseases.

Managing Osteoporosis: A Survey of Knowledge, Attitudes and Practices among Primary Care Physicians in Israel.

BACKGROUND: Osteoporosis is a systemic skeletal disorder characterized by impaired bone quality and microstructural deterioration leading to an increased propensity to fractures. This is a major health problem for older adults, which comprise an increasingly greater proportion of the general population. Due to a large number of patients and the insufficient availability of specialists in Israel and worldwide, osteoporosis is treated in large part by primary care physicians. We assessed the knowledge of primary care physicians on the diagnosis and treatment of osteoporosis. METHODS: Physician's knowledge, sources of knowledge acquisition and self-evaluation of knowledge were assessed using a multiple choice questionnaire. Professional and demographic characteristics were assessed as well. RESULTS: Of 490 physicians attending a conference, 363 filled the questionnaires (74% response rate). The physicians demonstrated better expertise in diagnosis than in medications (mechanism of action, side effects or contra-indications) but less than for other treatment related decisions. Overall, 50% demonstrated adequate knowledge of calcium and vitamin D supplementation, 51% were aware of the main therapeutic purpose of osteoporosis pharmacotherapy and 3% were aware that bisphosphonates should be avoided in patients with impaired renal function. Respondents stated frontal lectures at meetings as their main source of information on the subject. CONCLUSION: The study indicates the need to intensify efforts to improve the knowledge of primary care physicians regarding osteoporosis, in general; and osteoporosis pharmacotherapy, in particular.

Blood levels of vitamin D and health-functional status in asymptomatic individuals: a cross sectional study.

BACKGROUND: Recently issued guidelines do not recommend screening for vitamin D deficiency in asymptomatic adults. The large range of health effects that have been associated with vitamin D deficiency raises the possibility that vitamin D levels may be a marker of poor health status rather than a cause of it. We investigated an association between vitamin D level and health-functional status. METHODS: This cross-sectional study comprised 205 individuals who had taken a first plasma vitamin D test and were not symptomatic for vitamin D deficiency. During an interview, participants responded to questions regarding demographic information and their exposure to the sun, as well as a health-functional status questionnaire - World Organization of Family Doctors/COOP charts. Correlations between study variables and vitamin D levels were calculated. A stepwise linear regression was performed to estimate variables that independently predict vitamin D levels. RESULTS: The participants were 51 men and 154 women, mean age 41 years. Vitamin D level was positively correlated with weekend sun exposure and negatively correlated with body mass index (BMI). A reported positive change in health over the previous 2 weeks correlated with a higher vitamin D level. Individuals with higher vitamin D levels were more likely to report participation in physical activity and to report capability of performing daily activities. A total of 176 (86%) of the study population was deficient in vitamin D, according to a level <30 ng mL-1 . Vitamin D deficiency was associated with older age, higher BMI, Arab compared with Jewish ethnicity (darker skin), and religious identification (more body covering). In the multivariate analysis older age, female gender, religious identification, Arab ethnicity, higher BMI, sunscreen use and low exposure to sun during the weekdays all associated with lower vitamin D levels. CONCLUSION: No parameter of functional health demonstrated capability of distinguishing vitamin D deficiency among healthy young to middle-aged adults.

Efficacy of dry needling for treatment of myofascial pain syndrome.

Myofascial pain is a major cause of musculoskeletal regional pain. Myofascial pain, which is a high-prevalence but eminently treatable condition, is almost universally underdiagnosed by physicians and undertreated by physical therapy modalities. Large numbers of patients can be left suffering in chronic pain for years. Dry needling, also referred to as Intramuscular Stimulation, is a method in the arsenal of pain management which has been known for almost 200 years in Western medicine, yet has been almost completely ignored. With the increase in research in this field over the past two decades, there are many high-quality studies that demonstrate dry needling to be an effective and safe method for the treatment of myofascial pain when diagnosed and treated by adequately-trained physicians or physical therapists. This article provides an overview of recent literature regarding the treatment of myofascial pain syndrome, evidence for the efficacy of dry needling as a central component of its management, and a glimpse at developments in recent imaging methods to aid in the treatment of these problems.

Prevalence of and change in the prescription of methylphenidate in Israel over a 2-year period.

INTRODUCTION: The use of methylphenidate for the treatment of attention deficit-hyperactivity disorder (ADHD) has increased dramatically in the past decade in some countries in Europe and North America. In response to a public debate in Israel, several Knesset members introduced a legislative initiative that aims to limit the prescription of methylphenidate by physicians. The objective of this study was to examine the rate methylphenidate prescriptions dispensed for the treatment of ADHD in children in northern and central Israel in 1999 and 2001. PATIENTS AND STUDY DESIGN: The population included all children aged 0-18 years living in central or northern Israel and insured by the largest national health management organisation who were prescribed methylphenidate at least once in 1999 or 2001. This was a population-based prevalence study comparing the two timepoints using data from the health management organisation and descriptive statistics. RESULTS: The overall 1-year prevalence of methylphenidate prescriptions dispensed to children was 1.01% in 1999 and 1.22% in 2001 (relative risk [RR] 1.21, 95% CI 1.15-1.26), an increase of 21%. Seventy-seven percent of those prescribed methylphenidate were boys. The prescription rate ranged from 0.2% (RR 1.24, 95% CI 0.76-2.05) in Arabic cities to 5.99% (RR 1.19, 95% CI 1.09-1.30) in kibbutzim; this wide variation by type of residence apparently involved cultural, racial and economic factors. CONCLUSION: Israel shows no unusual or unexpected patterns in methylphenidate prescriptions dispensed to children and a lesser increase over time than other developed countries. This suggests that limiting physician freedom to prescribe methylphenidate to children may not be justified.

Assessment of participation in physical activities and relationship to socioeconomic and health factors. The controversial value of self-perception.

Physician counseling on physical activities for sedentary people is usually based on anamneses. The aim of the present study was to investigate the accuracy of self-perception of participation in physical activities, and the correlation of physical activity with background factors. A random sample of 276 individuals aged 20-65 years completed a detailed questionnaire on type and intensity of physical activity and associated socioeconomic and health factors. Physical activities were divided into work, leisure-time, and sports and rated according to Baecke's four-item index. In addition, subjects answered a yes/no item that resembled the general question regarding physical activity usually asked by physicians in a typical anamnesis. About half of the population was found to lead a sedentary life-style. The lower the level of education, the greater the physical activity at work. Males had a higher sports index than females. Interestingly, 1.3% of those with a high questionnaire score reported on the anamnesis question that they did not engage in regular physical activity, whereas 17.5% with a low questionnaire score answered "yes" to the last item. In conclusion, self-reports on physical activity may be inaccurate and to ensure proper counseling, primary care physicians must place greater weight on the patient history.

Somatization in response to undiagnosed obsessive compulsive disorder in a family.

BACKGROUND: Somatization is a common problem in primary care and often presents puzzling problems for the family physician. A family or contextual approach is often useful in investigating and treating refractory symptoms. CASE PRESENTATION: A 63 year-old patient presented to his family physician with recurrent episodes of syncope, weakness and various other somatic symptoms. Lengthy clinical investigations found no organic pathological findings but a brief family assessment by the family physician revealed that the patient's wife was the "hidden" patient. Successful treatment of the patient's wife led to full recovery for both. CONCLUSIONS: Exploration and treatment of the family context may often hold the key to the solution of difficult problems in somatizing patients.

Increasing the satisfaction of general practitioners with continuing medical education programs: a method for quality improvement through increasing teacher-learner interaction.

BACKGROUND: Continuing medical education (CME) for general practitioners relies on specialist-based teaching methods in many settings. Formal lectures by specialists may not meet the learning needs of practitioners and may cause dissatisfaction with traditional CME. Increasing learner involvement in teaching programs may improve learner satisfaction. METHODS: A quality improvement program for CME for 18 general practitioners in the Tel Aviv region was designed as a result of dissatisfaction with traditional CME activities. A two-step strategy for change was developed. The CME participants first selected the study topics relevant to them from a needs assessment and prepared background material on the topics. In the second step, specialist teachers were invited to answer questions arising from the preparation of selected topics. Satisfaction with the traditional lecture program and the new participatory program were assessed by a questionnaire. The quality criteria included the relevance, importance and applicability of the CME topic chosen to the participant's practice, the clarity of the presentation and the effective use of teaching aids by the lecturer and the potential of the lecturer to serve as a consultant to the participant. RESULTS: The participatory model of CME significantly increased satisfaction with relevance, applicability and interest in CME topics compared to the traditional lecture format. CONCLUSIONS: Increased learner participation in the selection and preparation of CME topics, and increased interaction between CME teachers and learners results in increased satisfaction with teaching programs. Future study of the effect of this model on physician performance is required.

Severe vitamin B12 deficiency in an infant associated with a maternal deficiency and a strict vegetarian diet.

The authors present a case of severe megaloblastic anemia and neurologic damage due to vitamin B12 deficiency in a 6-month-old infant. The cause of the vitamin deficiency was a maternal dietary deficiency because of a strict vegetarian diet and prolonged breast-feeding. The importance of early recognition of significant maternal vitamin B12 deficiency during pregnancy and lactation in vegetarians is emphasized so that appropriate supplementation can be given and irreversible neurologic damage in the infant prevented.

Patient and family physician preferences for care and communication in the eventuality of anthrax terrorism.

BACKGROUND: The threat of bioterrorism consequent to the September 11, 2001 attack in the USA generated suggestions for improved medical response mainly through hospital preparedness. OBJECTIVES: The aim of the present study was to investigate the impact of this period of tension on patients' first choice for care and for receiving relevant information, and on primary care doctors' feelings of responsibility in the eventuality of an anthrax attack. METHODS: During October 11-31, 2001, 500 patients from 30 clinics throughout Israel were asked to complete a questionnaire on their awareness of the anthrax threat, measures taken to prepare for it, and preferred sources of care and information. Their 30 physicians, and an additional 20, completed a questionnaire on knowledge about anthrax and anthrax-related patient behaviours and clinic visits. RESULTS: The outstanding finding was the low rate (30%) of patients who chose the hospital emergency department as their first choice for care or information if they were worried about an anthrax attack or the media communicated that an attack was in progress. The other two-thirds preferred their family doctor or the health authorities. Most of the physicians (89%) felt it was their responsibility to treat anthrax-infected patients and that they should therefore be supplied with appropriate guidelines. CONCLUSION: This study suggests that in Israel, a country with a high degree of awareness of civil defence aspects, both patients and primary care doctors believe that family physicians should have a major role in the case of bioterrorist attacks. This must be seriously considered during formulation of relevant health services programmes.
