Respiratory medicine curriculum in Portuguese family medicine training: A Delphi study

BACKGROUND

Respiratory diseases (RD) constitute a significant part of the workload of family physicians. There is no consensus on what family doctors should know in this area but established methods for achieving consensus may help to overcome this.

OBJECTIVES

The purpose of the study was to obtain a national consensus on the required knowledge and skills in respiratory medicine for family medicine trainees after vocational training.

METHODS

A Delphi study was conducted via e-mail with a diverse panel of experts. We developed a Learning Curriculum Framework (LCF) with 399 items adapted from the Royal Australasian College of Physicians ..÷ Respiratory Medicine Advanced Training Curriculum. The LCF was submitted to the experts in two rounds for consensus. Consensus was considered for items that had an agreement of 80% in the classifications above 4 on a scale of importance that ranged from 1 (not important) to 5 (very important).

RESULTS

Consensus was obtained for 159 items (38.8%). These included structure and function of the respiratory tract (0.6%), presenting problems (21.4%), diagnosis (7.5%), interventions and prevention (11.3%), COPD-emphysema (12.6%), tumours (3.1%), infections (10.7%), tuberculosis (5.7%), HIV (1.3%), thromboembolic disease (2.5%), pleural-pulmonary disease (3.1%), pregnancy (0.6%) and sleep disorders (3.8%). Items on iatrogenic diseases and respiratory research did not reach consensus.

CONCLUSIONS

Consensus on the respiratory medicine curriculum may contribute to further development of the vocational training curriculum in Portugal. This approach may help teachers in other countries in Europe to develop curricula for respiratory medicine and other areas of general practice.

Placebo prescription and empathy of the physician: A cross-sectional study

Background: Empathy in the patient–physician relationship is a major component in an effective placebo treatment, as in every medical treatment. Understanding the role of empathy of the physician in the placebo effect may help dissect some of the context variables responsible for the effectiveness of the placebo.

Objectives: To determine the frequency of placebo prescription, doctors’ beliefs, motivation, and attitudes to placebos in general practice in northern Portugal and to test the association between placebo prescription and physician empathy.

Methods: A cross-sectional study was conducted between November 2014 and January 2015 among general practice specialists and interns from 14 health centres in a northern Portuguese health region. The self-report questionnaire included the Portuguese version of the Jefferson scale of physician empathy (JSPE) and a questionnaire about placebo prescription. Associations between demographic variables, JSPE score, prescription of placebo, and the attitudes to placebo score were tested with the chi-squared statistic, student t-tests for independent samples, and Pearson correlation.

Results: The study included 93 general practitioners (GP) (response rate: 74%). Placebos were prescribed by 73% (n = 68) of the respondents. GPs who prescribe placebo are significantly younger (mean age = 38.4 years; SD = 11.1; t (90) = 2.98, P <.05, d = 0.67) than non-prescribers (mean age =46.5 years; SD =13.3). Favourable attitudes towards placebo prescription are associated with higher empathy scores (R = 0.310, P <.01).

Conclusion: Placebo prescription is frequent and associated with empathy from the prescriber, especially among younger GPs.

Twenty-five years of the international Bled course for teachers of family medicine in Europe: Glancing back and looking forward

The international Bled course for teacher training has played a central role in faculty development in family medicine for the past 25 years. The course was originally designed to promote faculty development for family medicine teachers in the new academic discipline of family medicine in Slovenia in 1990 and to introduce new topics into the family medicine curriculum. In this background paper, we perform a SCOT analysis (strengths, challenges, opportunities, and threats) of the current course, evaluating participant feedback and reviewing past topics and their impact on local and international teaching programmes. We also review the place of the course in the context of other teacher-training programmes in family medicine in Europe. We found that the structure and learning aims of the Bled course have remained stable over 25 years. It provides a safe, well-structured learning environment for the participants even though the course topic is different every year. The course has had a significant impact on curriculum development and teacher training in Slovenia as well as in many other countries in Europe and beyond. Because of the positive impact of the course and the high degree of satisfaction of the participants and course directors, it seems worthwhile to continue this endeavour. New directions for the course will depend on the learning needs of the participants and the evolving medical curricula in the countries they represent.

The respiratory research agenda in primary care in Portugal: a Delphi study

BACKGROUND

A research agenda can help to stimulate and guide research. The International Primary Care Respiratory Group (IPCRG) published a Research Needs Statement (RNS) in 2010 in which 145 research questions were identified. In 2012, priorities for respiratory research were established, based on these questions. To date, there has been no statement on primary care respiratory research needs in Portugal. The aim of the study was to develop a national consensus on research priorities in respiratory diseases in primary care in Portugal and to assess the applicability of the priorities for respiratory research set by the IPCRG.

METHOD

We conducted a Delphi study by electronic mail with a panel of experts on respiratory disease from primary and secondary care in Portugal. In the first round, the research needs in respiratory disease in Portugal were identified. In the second round, 196 research questions in six disease areas, derived from the first round and from the IPCRG Respiratory needs statement, were prioritised on a five-point Likert-type scale. In the third round, the questions were prioritized again with feed-back provided on the median scores for each item in the second round. Consensus was considered to have been reached when 80 % of the participants gave a score of 4 or 5 out of five on a given item.

RESULTS

The 40 experts identified 121 respiratory research questions in Round 1 and expressed their views on 196 questions in Rounds 2 and 3. Twelve research questions (6 %) reached consensus. There were five questions in the asthma domain on early diagnosis, pulmonary function tests, the use of inhalers, and adherence to treatment. There were four questions in the chronic obstructive pulmonary disease domain on vaccinations, on routine monitoring and evaluation of treatment, on diagnosis, and on adherence to treatments. There was one question in the smoking domain on the effects of brief counselling. There were two questions on respiratory tract infections on the treatment of children and on the prescription of antibiotics. An additional 23 research questions (12 %) achieved consensus between 75 and 79 %.

CONCLUSION

The results reflect the Portuguese reality in response the international agenda for research on respiratory diseases published by the IPCRG. They can support the development of future respiratory disease research in Portugal.

[Cervical cancer screening: target age bracket, screening frequency and screening method: review of recent evidence and comparison with the Portuguese performance indicator]

The scope of this review was to assess the strength of evidence of Portuguese performance indicators on Cervical Cancer screening: (1) age group of the women that should be screened for cervical cancer; (2) frequency of screening; and (3) the best method for screening. The following MeSH terms were searched: vaginal smears, age groups, periodicity, methods, uterine cervical cancer. Articles not reflecting the study objectives or not available in English, Portuguese or Spanish were excluded. The SORT classification was used to rate the articles selected.Of the 197 articles found, 9 that met all study criteria were selected for inclusion in this review. These included 1 systematic review, 1 randomized controlled clinical trial, 2 retrospective studies and 5 clinical guidelines. The authors also chose to include 4 clinical guidelines and two systematic reviews relevant to the Portuguese population even though they did not appear in the initial search of the literature. The studies suggest screening women between the ages of 21 to 25 years and 65 years of age, once every three years using conventional cytology. There is still controversy regarding the three objectives of this study (target age bracket, screening frequency and screening method).

[Recommended age groups and frequency of mammography screening: a systematic review]

The scope of this review was to assess the strength of evidence for the current Portuguese performance indicator on breast cancer screening with mammography in order to determine the recommended age group and periodicity for screening. A search for articles was conducted in the main international databases of medical literature. Articles published between January 2006 and January 2012 addressing the objectives of this review were included. The SORT taxonomy was used to classify the results. Of the 253 articles, five articles met the inclusion criteria and were selected for review. These included three systematic reviews, one meta-analysis and one clinical guideline based on a systematic review. A reduction in breast cancer mortality with mamography screening was the outcome in all articles selected. Mammography screening between 50 and 69 years was recommended in all articles that assess this age group. The clinical guidelines recommended screening every two years. In conclusion, the current literature recommends mammography for women every two years between the ages of 50 and 69 years. This is consistent with the current performance indicator for breast cancer screening in Portugal.

Asthma control, quality of life, and the role of patient enablement: a cross-sectional observational study

Background:

Self-assessment of asthma and a stronger doctor-patient relationship can improve asthma outcomes. Evidence for the influence of patient enablement on quality of life and the control of asthma is lacking.

Aims:

To assess asthma severity, medication use, asthma control, and patient enablement in patients with asthma treated in primary care and to study the relationship between these variables and quality of life.

Methods:

A cross-sectional study was conducted in an urban clinic in northern Portugal. Data were collected from both clinical records and questionnaires from a random sample of asthma patients. The modified Patient Enablement Instrument, the Asthma Quality of Life Questionnaire, and the Asthma Control Questionnaire were used. Peak expiratory flow and forced expiratory volume in one second (FEV₁) were measured. Receiver operating characteristic curve analysis was performed to establish cut-off values for the quality of life measurements. The associations between enablement, asthma control, and quality of life were tested using logistic regression models.

Results:

The study sample included 180 patients. There was a strong correlation between asthma control and quality of life (r=0.81, p<0.001). A weak association between patient enablement and asthma control and quality of life was found in the logistic regression models. Poor control of asthma was associated with female gender, concomitant co-morbidities, reduced FEV₁, and increased severity of asthma.

Conclusions:

The weak correlation between enablement and asthma control requires further study to determine if improved enablement can improve asthma outcomes independent of gender, severity, and concomitant co-morbidities. This study confirms the strong correlation between asthma control and quality of life.

Intranasal steroids for acute sinusitis

BACKGROUND

Acute sinusitis is a common reason for primary care visits. It causes significant symptoms and often results in time off work and school.

OBJECTIVES

We examined whether intranasal corticosteroids (INCS) are effective in relieving symptoms of acute sinusitis in adults and children.

SEARCH METHODS

We searched CENTRAL 2013, Issue 4, MEDLINE (January 1966 to May week 2, 2013), EMBASE (1990 to May 2013) and bibliographies of included studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing INCS treatment to placebo or no intervention in adults and children with acute sinusitis. Acute sinusitis was defined by clinical diagnosis and confirmed by radiological evidence or by nasal endoscopy. The primary outcome was the proportion of participants with either resolution or improvement of symptoms. Secondary outcomes were any adverse events that required discontinuation of treatment, drop-outs before the end of the study, rates of relapse, complications and return to school or work.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data, assessed trial quality and resolved discrepancies by consensus.

MAIN RESULTS

No new trials were found for inclusion in this update. Four studies involving 1943 participants with acute sinusitis met our inclusion criteria. The trials were well-designed and double-blind and studied INCS versus placebo or no intervention for 15 or 21 days. The rates of loss to follow-up were 7%, 11%, 41% and 10%. When we combined the results from the three trials included in the meta-analysis, participants receiving INCS were more likely to experience resolution or improvement in symptoms than those receiving placebo (73% versus 66.4%; risk ratio (RR) 1.11; 95% confidence interval (CI) 1.04 to 1.18). Higher doses of INCS had a stronger effect on improvement of symptoms or complete relief: for mometasone furoate 400 µg versus 200 µg (RR 1.10; 95% CI 1.02 to 1.18 versus RR 1.04; 95% CI 0.98 to 1.11). No significant adverse events were reported and there was no significant difference in the drop-out and recurrence rates for the two treatment groups and for groups receiving higher doses of INCS.

AUTHORS' CONCLUSIONS

Current evidence is limited for acute sinusitis confirmed by radiology or nasal endoscopy but supports the use of INCS as a monotherapy or as an adjuvant therapy to antibiotics. Clinicians should weigh the modest but clinically important benefits against possible minor adverse events when prescribing therapy.

Assessing the impact of a school intervention to promote students' knowledge and practices on correct antibiotic use

The clinical efficacy of antibiotics depends on their correct use. Widespread ignorance and inappropriate attitudes to antibiotic use have been identified among consumers. In order to improve the knowledge of middle-school students on antibiotics and their correct use, 82 ninth-grade students were enrolled in a teaching activity. The teaching activity consisted of a slide show presentation followed by discussion in a regular class. To evaluate the impact of the teaching activity the students were asked to answer a questionnaire before and after the activity. This study aimed: (1) to evaluate knowledge on the use of antibiotics in students of two schools in the north of Portugal and (2) to evaluate the efficacy of the school intervention in improving students' knowledge on correct antibiotic use. We found lack of knowledge among students regarding antibiotic spectra and indications and incorrect attitudes in the pre-test. Significant increases in knowledge were observed after implementation of the teaching activity. Knowledge of the correct use of antibiotics for bacterial diseases rather than viral diseases rose from 43% to 76% in the post-test (p < 0.01). Knowledge of the risk of bacterial resistance to antibiotics from their incorrect use rose from 48% to 74% in the post-test (p < 0.05). We believe that it is important to reinforce the teaching activities on microbiology and antibiotic use at the middle school level.

Asthma incidence and accuracy of diagnosis in the Portuguese sentinel practice network

AIMS

Asthma is frequently under-diagnosed with a wide variation in incidence rates. We aimed to assess how physicians in a Portuguese sentinel practice network perform using standardised diagnostic criteria.

METHOD

Patients consulting one of the 43 network physicians with complaints suggestive of asthma were enrolled in the study over a four-year period. Symptom frequency and diagnoses of asthma were tabulated. Diagnostic accuracy was computed by dividing the rate of asthma diagnosis by the true rate using established diagnostic criteria.

RESULTS

Over four years, 43 physicians followed 32,103 patients (128,412 patient-years) and diagnosed asthma in 310. The diagnosis was confirmed in 260 cases, giving a true incidence rate of 2.02/1000/year (95% confidence interval 1.8 to 2.2) and an accuracy of diagnosis of 84%.

CONCLUSIONS

Asthma incidence approaches published rates if accepted criteria are used. Educational efforts to ensure more accurate diagnosis may improve outcomes for asthma patients.

Non-specific symptoms as clues to changes in emotional well-being

Background -

Somatic symptoms are a common reason for visits to the family physician. The aim of this study was to examine the relation between non-specific symptoms and changes in emotional well-being and the degree to which the physician considers the possibility of mental distress when faced with such patients.

Methods -

Patients who complained of two or more symptoms including headache, dizziness, fatigue or weakness, palpitations and sleep disorders over one year were identified from the medical records of a random sample of 45 primary care physicians. A control group matched for gender and age was selected from the same population. Emotional well-being was assessed using the MOS-SF 36 in both groups.

Results -

The study group and the control group each contained 110 patients. Completed MOS questionnaires were obtained from 92 patients, 48 patients with somatic symptoms and 44 controls. Sixty percent of the patients with somatic symptoms experienced decreased emotional well being compared to 25% in the control group (p = 0.00005). Symptoms of dizziness, fatigue and sleep disturbances were significantly linked with mental health impairments. Primary care physicians identified only 6 of 29 patients (21%) whose responses revealed functional limitations due to emotional problems as suffering from an emotional disorder and only 6 of 23 patients (26%) with a lack of emotional well being were diagnosed with an emotional disorder.

Conclusions -

Non-specific somatic symptoms may be clues to changes in emotional well-being. Improved recognition and recording of mental distress among patients who complain of these symptoms may enable better follow up and treatment.

Asthma in an urban population in Portugal: a prevalence study

Background

The prevalence and incidence of asthma are believed to be increasing but research on the true incidence, prevalence and mortality from asthma has met methodological obstacles since it has been difficult to define and diagnose asthma in epidemiological terms. New and widely accepted diagnostic criteria for asthma present opportunities for progress in this field. Studies conducted in Portugal have estimated the disease prevalence between 3% and 15%. Available epidemiological data present a significant variability due to methodological obstacles.

Aim

To estimate the true prevalence of asthma by gender and age groups in the population of the area covered by one urban Health Centre in Portugal.

Method

An observational study was conducted between February and July 2009 at the Horizonte Family Health Unit in Matosinhos, Portugal. A random sample of 590 patients, stratified by age and gender was obtained from the practice database of registered patients. Data was collected using a patient questionnaire based on respiratory symptoms and the physician's best knowledge of the patient's asthma status. The prevalence of asthma was calculated by age and gender.

Results

Data were obtained from 576 patients (97.6% response rate). The mean age for patients with asthma was 27.0 years (95% CI: 20.95 to 33.16). This was lower than the mean age for non-asthmatics but the difference was not statistically significant. Asthma was diagnosed in 59 persons giving a prevalence of 10.24% (95% CI: 8.16 to 12.32). There was no statistically significant difference in the prevalence of asthma by gender.

Conclusion

The prevalence of asthma found in the present study was higher than that found in some studies, though lower than that found in other studies. Further studies in other regions of Portugal are required to confirm these findings.

The effect of the Internet on the patient-doctor relationship from the patient's perspective: a survey from primary care

BACKGROUND

Internet use by patients as a source of information on health and disease is expanding rapidly with obvious effects on the doctor-patient relationship. Many of these effects remain undocumented or are poorly understood.

OBJECTIVES

To assess the use of the internet for health information by patients in primary care in Israel and their perception of the effects of internet use on their relationship with their doctor.

METHODS

A cross-sectional survey was conducted among a convenience sample of patients visiting 10 primary care clinics in central Israel using a questionnaire developed for this survey. The survey examined attitudes to using the internet for health-related information and attitudes to sharing this information with doctors. Associations between demographic variables, internet use and patient satisfaction with the doctor's response were tested using the chi-square statistic and t-tests.

RESULTS

Completed questionnaires were received from 138 patients; the response rate was 69%. Patients in the study sample had a high rate of internet access (87%), with many using the internet as a source of health information (41%) although most patients using the internet never share this information with their doctor (81%). Among those who share information with the doctor, most felt that this has a positive effect on the relationship (870/%). Few patients reported being referred to websites by the doctor (28%).

CONCLUSIONS

Internet use is prevalent in this population, though physicians may be unaware of this. Future study could examine the effects of doctors who ask patients actively about their internet use and inform them of relevant health information sources online.

Antimicrobial agents for treating uncomplicated urinary tract infection in women

BACKGROUND

Acute uncomplicated lower urinary tract infection (UTI) is one of the most common problems for which young women seek medical attention.

OBJECTIVES

To compare the efficacy, resistance development and safety of different antimicrobial treatments for acute uncomplicated lower UTI.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Renal Group's Specialised Register, MEDLINE, EMBASE and bibliographies of included studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing different classes of antimicrobials for acute uncomplicated UTI in women were included. The outcomes of interest were symptomatic and bacteriological cure at short and long-term follow-up, resistance development, number of days to symptom resolution, days of work loss, adverse events and complications.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted the data and assessed study quality. Statistical analyses were performed using the random effects model and the results expressed as risk ratios (RR) with 95% confidence intervals (CI).

MAIN RESULTS

Trimethoprim-sulfamethoxazole (TMP-SMX) was as effective as fluoroquinolones in achieving short-term (RR 1.00, 95% CI 0.97 to 1.03) and long-term (RR 0.99, 95% CI 0.94 to 1.05) symptomatic cure. Beta-lactam drugs were as effective as TMP-SMX for short-term (RR 0.95' 95% CI 0.81 to 1.12) and long-term (RR 1.06' 95% CI 0.93 to 1.21) symptomatic cure. Short-term cure for nitrofurantoin was similar to that of TMP-SMX (RR 0.99' 95% CI 0.95 to 1.04) as was long-term symptomatic cure (RR 1.01' 95% CI 0.94 to 1.09).Fluoroquinolones were more effective than beta-lactams (RR 1.22, 95% CI 1.13 to 1.31) for short-term bacteriological cure. Rashes were more frequent in patients treated with TMP-SMX than with nitrofurantoin or fluoroquinolones and in patients treated with beta-lactam drugs compared to fluoroquinolones. Minimal data were available on the emergence of resistant strains during or after antimicrobial treatment.

AUTHORS' CONCLUSIONS

No differences were observed between the classes of antimicrobials included in this review for the symptomatic cure of acute uncomplicated UTI. Fluoroquinolones proved more effective than beta-lactams for the short-term bacteriological outcome, probably with little clinical significance. Individualised treatment should take into consideration the predictable susceptibility of urinary pathogens in local areas, possible adverse events and resistance development, and patient preference.

The competence of primary care doctors in the investigation of patients with elevated blood pressure: results of a cross-sectional study using clinical vignettes

BACKGROUND

Specific laboratory tests are required to ensure adequate management of patients with hypertension, according to internationally accepted guidelines. There is wide variation in doctor test ordering behaviour. Many factors are known to affect this. Little is known about the interaction between doctor, patient and practice characteristics. The current study was designed to explore this.

METHODS

A series of eight case vignettes was designed to examine test ordering behaviour among primary care doctors in Poland. The cases differed with regard to the level of blood pressure and the presence or absence of other cardiovascular risk factors, including diabetes. Doctors stated their choices of laboratory investigations needed in these cases. Their responses were compared with recommendations in the 2003 European Society of Hypertension/European Society of Cardiology hypertension guidelines. Associations between the correct responses and patient, doctor and practice characteristics were tested.

RESULTS

One hundred and twenty-five out of 192 invited doctors (65%) participated in the study. They ordered a mean of 4.9 laboratory tests per case. This represents 47.9% of the tests recommended by current guidelines. Older doctors working in smaller practices and private settings ordered fewer laboratory tests. Specialization in family medicine was associated with greater compliance with guidelines. Grade 2 hypertension and the presence of other risk factors of cardiovascular disease were associated with ordering more tests but the presence of diabetes did not improve compliance with guidelines.

CONCLUSIONS

Further educational efforts are needed to promote rational test ordering for hypertensive patients by Polish primary health care doctors.

Hormone replacement therapy and WONCA/COOP functional status: a cross-sectional population-based study of women in Israel

BACKGROUND

Current indications for hormone replacement therapy (HRT) for menopausal women include symptom relief, but recent studies have raised concerns about the safety of HRT. Little data are available on the effect of HRT on functional status of women taking hormonal preparations after menopause.

OBJECTIVE

To assess the association between hormonal replacement therapy and functional status in menopausal women.

METHODS

A cross-sectional survey, population-based study of 682 menopausal women between the ages of 50 and 70 years registered with six family physicians in central Israel. The main outcome measure was the functional status measured by the WONCA/COOP charts.

RESULTS

A total of 587 women (86%) completed questionnaires. Univariate analysis showed an association between current use of HRT and improved functional status. However this association was diminished in a regression analysis which controlled for sociodemographic status and health variables. The contribution of HRT to functional status was small but was found to be significant in the domains of general health status (1.9%, p<0.002), sleep (0.9%, p<0.044), physical activities (2.1%, p<0.001) and feelings (1.0%, p<0.033). The contribution of HRT to daily activities, social activities, change in health status and pain was not significant.

CONCLUSIONS

HRT use had a small contribution to improved functional status in half of the domains measured by the WONCA/COOP charts.

Competence of Polish primary-care doctors in the pharmacological treatment of hypertension

RATIONALE, AIMS AND OBJECTIVES

Compliance with treatment guidelines for hypertension is variable. This study assessed the competence of Polish general practitioners in compliance with hypertension treatment guidelines, and doctor and patient characteristics associated with compliance.

METHODS

The study was conducted on a random sample of Polish primary-care doctors working in clinics contracted by the national health insurance funds. Doctors completed a questionnaire consisting of eight case vignettes describing patients with elevated blood pressure. The cases differed on three variables relating to the level of blood pressure, the presence or absence of diabetes mellitus, and the presence or absence of other risk factors. Doctors were asked to give their treatment decision for each case. Demographic data and details of the doctor's practice were also collected. Treatment decisions were tabulated, and associations between doctor and patient characteristics and treatments were assessed.

RESULTS

One hundred twenty-five doctors (65% response rate) completed the questionnaire. Compliance with treatment guidelines was judged to be 51%. Poor compliance with guidelines was noted for patients with diabetes mellitus. The level of blood pressure was the strongest predictor of drug treatment. Angiotensin-converting enzyme inhibitors were the most frequently prescribed medications. Appropriate decisions were associated with practice in large cities.

CONCLUSIONS

Compliance with hypertension treatment guidelines was judged to be poor in this study of a sample of Polish primary-care doctors using case vignettes to test competence. Additional emphasis on hypertension guidelines in training doctors is needed, especially for diabetic patients and for doctors outside urban centres.

An anatomy of conflicts in primary care encounters: a multi-method study

BACKGROUND

Medical consultations are replete with conflicts, particularly in the current era of explicit and implicit rationing practices in health care organizations. Although such conflicts may challenge the doctor-patient relationship, little is known about them or their consequences.

AIMS

To systematically describe the nature of doctor-patient conflicts in medical encounters and the strategies physicians use when faced with conflicts.

METHODS

Analysis of 291 videotaped routine encounters with 28 general practitioners, using a novel adaptation of the Roter interaction analysis system software, provided quantitative empirical data on the conflicts and on the communication process. Seven focus groups (56 GPs) provided qualitative insights and guided the analysis.

RESULTS

Conflicts were identified in 40% of consultations; 21% of these were related to the rationing of health care resources. In conflictual encounters, both the opening and closing phases of the encounter were shorter than in non-conflictual encounters. In coping with resource rationing, the commonest strategy was to accept the dictates of the system without telling the patients about other options. When conflict of this type occurred, doctors showed more opposition to the patients rather than empathy.

CONCLUSIONS

Doctors often face conflicts in their routine work, but resource-related conflicts are especially difficult and expose the dual loyalties of the doctor to the patient and to the system. Insights derived from this research can be used to design training interventions that improve doctors' efficacy in coping with conflicts and ultimately allow them to provide better patient care.

Faculty development for teachers of family medicine in Europe: reflections on 16 years' experience with the international Bled course

BACKGROUND

Instruction in principles and methods of medical education is a core component of the training of medical teachers. Curricula for new medical teachers have developed across Europe, but few European courses have had the success of the EURACT Bled course for teachers of family medicine. The course focuses on practical issues in medicine and the professional development of physicians. This article describes 16 years' experience with the Bled course for teachers in general practice/family medicine (GP/FM).

COURSE STRUCTURE

The course is centred on the preparation of a teaching module, exploring a specific theme in family medicine. The main teaching methods used are: keynote lectures, small group sessions, field work and preparation of a teaching module by the participants.

OUTCOMES

This course has attracted 555 participants from 20 countries since 1992. The course and its outputs have been applied in undergraduate and postgraduate teaching, and in continuous professional development (CPD) in several countries. It is a respected forum for faculty development. The experience of the Bled course suggests that academic medicine may be better able to fulfil its responsibilities by paying attention to relevant topics and using appropriate methods in undergraduate and postgraduate medical curricula.

Intranasal steroids for acute sinusitis

BACKGROUND

Acute sinusitis is a common reason for primary care visits. It causes significant symptoms and often results in time off work and school.

OBJECTIVES

We examined whether intranasal corticosteroids (INCS) are effective in relieving symptoms of acute sinusitis.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library, 2008, issue 4) which contains the Acute Respiratory Infections Group's Specialized Register, MEDLINE (January 1966 to October 2008), EMBASE (1990 to October 2008) and bibliographies of included studies.

SELECTION CRITERIA

Randomized controlled trials (RCTs) were considered eligible if they compared INCS treatment to placebo treatment of a control group for acute sinusitis; acute sinusitis was defined by clinical diagnosis and confirmed by radiological evidence or by nasal endoscopy. The primary outcome was the proportion of participants with either resolution or improvement of symptoms. Secondary outcomes were any adverse events that required discontinuation of treatment, drop-outs before the end of the study, rates of relapse, complications and return to school or work.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted the data, assessed trial quality and resolved discrepancies by consensus.

MAIN RESULTS

Four studies with 1943 participants met the inclusion criteria. The trials were well designed, double-blind, placebo controlled in which the included participants had acute sinusitis. The treatment assigned was INCS versus control treatment for 15 or 21 days. The rates of loss to follow up in the studies were 7%, 11%, 41% and 10%. When the results from the three trials included in the meta-analysis were combined, participants receiving INCS were more likely to have resolution or improvement of symptoms than those receiving placebo (73% versus 66.4%; risk ratio (RR) 1.11; 95% CI 1.04 to 1.18). Higher doses of INCS had a stronger effect on improvement or complete relief of symptoms: for mometasone furoate (MFNS) 400 mcg versus 200 mcg, (RR 1.10; 95% CI 1.02 to 1.18 versus RR 1.04; 95% CI 0.98 to 1.11). No significant adverse events were reported and there was no significant difference in the drop-out and recurrence rate for the two treatment groups and for groups receiving higher doses of INCS.

AUTHORS' CONCLUSIONS

For acute sinusitis confirmed by radiology or nasal endoscopy, current evidence is limited, but supports the use of INCS as a monotherapy or as an adjuvant therapy to antibiotics. Clinicians should weigh the modest but clinically important benefits against possible minor adverse events when prescribing therapy.

Portuguese students' knowledge of antibiotics: a cross-sectional study of secondary school and university students in Braga

Background

Recent surveys show that the knowledge of the general public about the correct use of antibiotics is limited. This contributes to the problem of inappropriate antibiotic use, leading to a progressive loss of bacterial sensitivity to these drugs and the spreading of resistant strains of bacteria.

Methods

In this cross-sectional study, a questionnaire about antibiotic use was given to a sample of students in the 9^th and 12^th grades of secondary school and in the first year of university in the north of Portugal.

Results

349 students returned completed questionnaires. Deficits were found in the students' knowledge of antibiotics and their correct use. Only 4% of 9^th grade students were aware that antibiotics are used to treat bacteria only, while 14% of 12^th grade students and 29% of first-year university students were aware of this. Fewer students were aware that antibiotics are used to treat tuberculosis. There were deficiencies in the knowledge of timing and duration of therapy. However close to 70% of these students are aware that inappropriate use of antibiotics can contribute to resistance to these drugs.

Conclusion

This study has observed a lack of general knowledge on correct antibiotic use in Portugal, as has been found in other countries. Since this may be due to a lack of formal education on this subject, we believe that a teaching unit on infectious diseases should be included in the 9^th and 12^th grades, in all curricular areas, with emphasis on bacterial and viral pathogens and correct antibiotic use. In addition, education on the correct use of medications may need to begin at much earlier ages.

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.

Dietary calcium supplementation for preventing colorectal cancer and adenomatous polyps

BACKGROUND

Several dietary factors have been considered to be involved in the increasing incidence of colorectal cancer in industrialised countries. Experimental and epidemiological evidence has been suggestive but not conclusive for a protective role for high dietary calcium intake. Intervention studies with colorectal cancer as an endpoint are difficult to perform owing to the large number of patients and the long follow-up required; studies using the appearance of colorectal adenomatous polyps as a surrogate endpoint are therefore considered in reviewing the existing evidence.

OBJECTIVES

This systematic review aims to assess the effect of supplementary dietary calcium on the incidence of colorectal cancer and the incidence or recurrence of adenomatous polyps.

SEARCH STRATEGY

We searched the Cochrane Controlled Trials Register, the Cochrane Colorectal Cancer Group specialised register, MEDLINE, Cancerlit , and Embase, to July 2007. The reference lists of identified studies were inspected for further studies, and the review literature was scrutinized.

SELECTION CRITERIA

Randomised controlled trials of the effects of dietary calcium on the development of colonic cancer and adenomatous polyps in humans are reviewed. Studies of healthy adults and studies of adults at higher risk of colon cancer due to family history, previous adenomatous polyps, or inflammatory bowel disease were considered; data from subjects with familial polyposis coli are excluded. The primary outcomes were the occurrence of colon cancer, and occurrence or recurrence of any new adenomas of the colon. Secondary outcomes were any adverse event that required discontinuation of calcium supplementation, and drop-outs before the end of the study.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data, assessed trial quality and resolved discrepancies by consensus. The outcomes were reported as odds ratios (OR) with 95% confidence intervals (CI). The data were combined with the fixed effects model.

MAIN RESULTS

Two studies with 1346 subjects met the inclusion criteria. Both trials were well designed, double - blind, placebo controlled trials, included participants with previous adenomas. The doses of supplementary elemental calcium used were 1200 mg daily for a mean duration of 4 years, and 2000 mg/day for three years. The rates of loss to follow -up were 14 % and 11%. For the development of recurrent colorectal adenoma, a reduction was found (OR 0.74, CI 0.58,0.95) when the results from both trials were combined.

AUTHORS' CONCLUSIONS

Although the evidence from two RCTs suggests that calcium supplementation might contribute to a moderate degree to the prevention of colorectal adenomatous polyps, this does not constitute sufficient evidence to recommend the general use of calcium supplements to prevent colorectal cancer.

Current primary care physician interventions to promote smoking cessation in Israel: an observational study

BACKGROUND

Smoking continues to be the most significant preventable cause of morbidity and early mortality in the developed world. Primary care physicians are not fufilling their potentially vital and effective role with regard to tobacco use and dependence.

OBJECTIVES

To evaluate current primary care physician practise in promoting smoking cessation.

METHODS

This observational study evaluated physician recording of smoking status by analysis of patients' electronic medical records. The 126 primary care physicians were based in 23 Tel Aviv clinics treating 144,811 patients. We also assessed additional physician anti-smoking activities by a telephone questionnaire of 178 randomly selected patients.

RESULTS

Analysis of the EMRs revealed that an average of 4.4% of patients per physician were recorded as smokers (as compared to a known smoking rate in this patient population of 24%). Male physicians recorded a significantly higher proportion of their patients as smokers in the EMR compared to female physicians (P < 0.05). A non-significantly higher rate of recording smokers was found in doctors who had completed postgraduate specialization in family medicine as compared to non-specialists. The questionnaire results show that 41% of patients interviewed recalled being asked if they smoked and 31% of smoking patients had been advised to quit. A non-significantly higher proportion of male as compared to female patients reported being questioned if they smoked, and if they were smokers, being advised to quit.

CONCLUSIONS

This study shows low rates of physician intervention to promote smoking cessation. It appears that a large proportion of the primary care physicians surveyed do not follow recommendations to promote smoking cessation among their patients. Intervention among adolesent smokers was particularly inadequate. Further action is needed to improve the performance of physicians in aiding smoking cessation.

Perceptions of family medicine and career choice among first year medical students: a cross-sectional survey in a Turkish medical school

Public attitudes to family medicine in Turkey have lagged behind its rapid academic development. The effect of undergraduate training in primary care on medical students' attitudes to family medicine has not been assessed. Objectives of this study were to assess the attitudes of first year medical students at Uludag University School of Medicine in Bursa, Turkey to family medicine and to determine their career aspirations. The study was a survey of the first year medical class in 2003-2004. The response rate was 95% (248/261 students). Students were positive about their choice of medicine as a career but had negative opinions of general practice. Female students were more positive in this respect. Initial preference was for specialization in fields other than general practice with little knowledge of the academic specialty of family medicine. Greater undergraduate exposure to family medicine is needed in order to increase knowledge of the field and influence student career choices.

The effect of drug information leaflets on patient behavior

BACKGROUND

The patient package insert, an information leaflet included by law in the packaging of prescription drugs, contains information for the user on the specific medication.

OBJECTIVES

To explore how patient information leaflets influence patient anxiety and adherence.

METHODS

A prospective cohort study was conducted in the practices of 15 family physicians. All patients receiving a new prescription for antibiotics, analgesics or antihypertensives were included. Physicians completed a questionnaire containing demographic data, assessment of the patient's anxiety, a prediction regarding adherence to the treatment, and response to the information leaflet. Patients were contacted by telephone for a follow-up structured interview. Patients' reactions to the information leaflet, adherence to treatment, and use of other sources of information on medication were assessed.

RESULTS

The study group comprised 200 patients. The patient information leaflet was read by 103 of them (51.5%). A higher educational level and a chronic medication were associated with reading the leaflet (P= 0.02 and 0.01 respectively). In 36 (34.9%), an increase in anxiety was reported after reading the leaflet. Among those who read the leaflet, 9.7% had decreased adherence. Patients who stated that reading the leaflet caused anxiety were more likely to reduce their use of the medication--7/36 (19.5%) vs. 3/67 (4.5%), P= 0.01.

CONCLUSIONS

The proportion of patients reading the drug information leaflet is about 50%, lower than that found in previous studies. Reading the leaflet did not greatly affect adherence but aroused anxiety and decreased adherence in some patients.

Steroids for acute sinusitis

BACKGROUND

Acute sinusitis is a common reason for primary care visits. It causes significant symptoms and often results in time off work and school.

OBJECTIVES

We examined whether intranasal corticosteroids (INCS) are effective in relieving symptoms of acute sinusitis.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2006), MEDLINE (January 1966 to December 2006), EMBASE (1990 to June 2006) and bibliographies of included studies.

SELECTION CRITERIA

Randomized controlled trials (RCTs) were considered eligible if they compared INCS treatment to placebo treatment of a control group for acute sinusitis; acute sinusitis was defined by clinical diagnosis and confirmed by radiological evidence or by nasal endoscopy. The primary outcome was the proportion of participants with either resolution or improvement of symptoms. Secondary outcomes were any adverse events that required discontinuation of treatment, drop-outs before the end of the study, rates of relapse, complications and return to school or work.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted the data, assessed trial quality and resolved discrepancies by consensus.

MAIN RESULTS

Four studies with 1943 participants met the inclusion criteria. The trials were well designed, double-blind, placebo controlled in which the included participants had acute sinusitis. The treatment assigned was INCS versus control treatment for 15 or 21 days. The rates of loss to follow up in the studies were 7%, 11%, 41% and 10%. When the results from the three trials included in the meta-analysis were combined, participants receiving INCS were more likely to have resolution or improvement of symptoms than those receiving placebo (73% versus 66.4%; RR 1.11; 95% CI 1.04 to 1.18). Higher doses of INCS had a stronger effect on improvement or complete relief of symptoms: for mometasone furoate (MFNS) 400 mcg versus 200 mcg, (RR 1.10; 95% CI 1.02 to 1.18 versus RR 1.04; 95% CI 0.98 to 1.11). No significant adverse events were reported and there was no significant difference in the drop-out and recurrence rate for the two treatment groups and for groups receiving higher doses of INCS.

AUTHORS' CONCLUSIONS

For acute sinusitis confirmed by radiology or nasal endoscopy, current evidence is limited, but supports the use of INCS as a monotherapy or as an adjuvant therapy to antibiotics. Clinicians should weigh the modest but clinically important benefits against possible minor adverse events when prescribing therapy.

Preventive adolescent health care in family practice: a program summary

The AMA Guidelines for Adolescent Preventive Services (GAPS) has been the cornerstone of preventive care for teenagers since its publication in 1994. Despite this, there has been little documentation of their implementation in the family medicine literature. This article gives an overview of a family practice-based adolescent preventive health program based on GAPS recommendations, and reports on compliance, feasibility and health issues. A Community-Oriented Primary Care (COPC) program targeted all adolescent patients aged 12-18 years in two Israeli family practices. 321 teenagers were invited to participate. Every 7th and 10th grader was invited for a preventive health visit with the family physician and nurse. The visits included a medical evaluation, screening and counseling regarding health issues recommended by GAPS, and counseling regarding personal health concerns. Parents were also invited to meet with the staff. 184 (57%) of the adolescents invited for health visits attended. The overall visit time was 47 minutes, including 12 minutes for a questionnaire and 35 minutes with providers. Common biomedical problems included overweight, acne and dysmenorrhea. Health risk behaviors and psychosocial problems included cigarette or alcohol use, dieting, infrequent/never seat belt use, and feeling depressed. 78% wanted to discuss at least one personal health issue. 27% were invited for follow-up visits. Only 3% of the parents came for visits. A community-oriented approach facilitates bringing adolescents for preventive health visits. Many previously undetected health issues, particularly psychosocial and behavioral, are revealed during these visits. A concerns checklist aids in addressing personal health concerns.

The role of periodic mortality case review sessions in a primary care teaching clinic

BACKGROUND

Maintaining a death register and holding staff discussions about patients who died can aid the physician in audit and research, which will lead to improved care of the terminally ill and the bereaved and to the development of prevention strategies. These issues are important for students and residents as well.

OBJECTIVES

To review the value of mortality-case discussions in primary care clinics, particularly teaching clinics.

METHODS

The clinic death register, instituted in 1998, includes age, gender, cause of death, place of death, relevant illnesses, and support provided to the patient before the death. In the half-yearly sessions, the data are reviewed, and individual cases that had an emotional impact on the staff, or information that can bring about changes in future care are discussed by the clinic staff and trainees.

RESULTS

In our clinic 233 deaths occurred during a 6 year period (1998-2003). The crude all-cause mortality rate was 7.1/1000. The median age was 80 years old. Neoplastic causes were slightly more frequent than cardiovascular causes of death. Only 15% died at home; 20% lived alone and 70% lived with a spouse or family members before the death. Topics discussed in the mortality review meetings include identifying pre-suicidal patients, when to hospitalize the sick elderly, dealing with the anger of bereaved families, and ensuring proper home care for terminal patients.

CONCLUSIONS

We recommend keeping a death register and conducting mortality review sessions in order to improve the quality of care, emotional support of the staff, and training students and residents about the complex issues surrounding the death of patients.

Adjuvant prednisone therapy in pharyngitis: a randomised controlled trial from general practice

BACKGROUND

Acute pharyngitis is a frequent and well-documented complaint in general practice but the associated suffering has remained largely unaddressed in the literature. Evidence, however, from five randomised controlled trials suggests that corticosteroids may be useful in relieving pain and discomfort arising from the condition.

AIM

To determine if short-acting oral therapy with prednisone was more effective than placebo in alleviating the suffering from acute pharyngitis in adults in a general practice setting.

DESIGN OF STUDY

Randomised placebo-controlled trial.

SETTING

General practice in Israel.

METHOD

Patients with acute pharyngitis were randomised to receive 60 mg prednisone orally for 1 or 2 days, or identical placebo treatment. The main outcome measures were throat pain, measured by a visual analogue scale at 12, 24, 48 and 72 hours after presentation, time off work, fever, dysphagia, recurrence of symptoms and bacterial recurrence.

RESULTS

Patients treated with prednisone experienced more rapid throat pain resolution than those in the placebo group. No adverse effects were reported nor any differences between the two groups regarding either symptom or positive bacterial culture recurrence.

CONCLUSION

Short-acting oral steroid therapy is effective for shortening throat pain duration in acute pharyngitis.

[The creation of a national faculty development program in Israel for family physicians]

University Departments from many countries recruit their faculty members for academic duties without prior formal training (specific for their jobs). This has been the common approach in Israel. Other countries however, have created faculty development (FD) programs to help new faculty accomplish their new tasks. This article describes the creation of the first National Faculty Development Program in Israel for Family Physicians. The main goals of a comprehensive FD program are to improve vitality in education, promote academic excellence and develop professional and organizational leadership. In 1998, the Israeli Society of Teachers in Family Medicine decided to develop a National Program to deal with basic FD requirements. Family Physicians and educationalists worked together at its development and cooperated in co-teaching. The program was launched in 2001 and we are now in the process of evaluating the first year and the development of the second course. We chose a format similar to the program from the University of Toronto. Twenty-three family physicians enrolled in the course. Half of the participants were born and trained in medicine in Israel. After completing the first year of this program, both participants and teachers provided positive feedback and requests were received for a second course for new participants.

The role of the staff meeting in resolving professional dilemmas in family medicine: concealing a diagnosis

Staff meetings are an integral part of the family medicine process but little has been written in the family medicine literature about their utility. In addition to filling administrative or management functions, the staff meeting can be a creative process for growth of staff members and the road to innovative solutions to clinical problems. Presentation of illness narratives is common in staff meetings. This report describes a staff meeting where a difficult doctor-patient narrative was presented by the treating physician. Contributions from all the doctors in the clinic at the meeting led to improved understanding of the problem and a shared sense of well-being.

Comparison of blood pressure measurements on the bare arm, below a rolled-up sleeve, or over a sleeve

BACKGROUND

This study examined the effect of measuring blood pressure below subjects' rolled-up sleeves, over the sleeve, or on the bare arm. This is an important day-to-day issue for the busy GP.

METHODS

The sample consisted of 201 subjects in family practice clinics and residents of a senior citizens' home. A digital device was used in all cases. Each participant underwent three blood pressure measurements in each of the following conditions in random order: cuff on bare arm; cuff over the sleeve; and cuff below the rolled-up sleeve. Differences between measurements were plotted against the mean blood pressure. Confounding factors controlled for were age, sex, clothing pressure and skin-fold thickness.

RESULTS

Differences in mean blood pressure readings between the clothed and bare arm were 0.5 mmHg (SD 7.5) for systolic pressure and 1 mmHg (SD 5) for diastolic pressure; neither difference was significant. However, in hypertensive subjects (>140 mmHg systolic), although the mean difference remained small (systolic pressure, 2 mmHg, SD 10), the range of difference for individual subjects was -32 mmHg to +22 mmHg.

CONCLUSION

The degree of clothing under the sphygmomanometer cuff does not have a clinically important effect on the blood pressure measurement. In patients known or found to be hypertensive, measurement on the bare arm is recommended.

How do examiners decide?: a qualitative study of the process of decision making in the oral examination component of the MRCGP examination

OBJECTIVE

To determine how examiners make decisions about candidates in the oral examination for membership in the Royal College of General Practitioners.

DESIGN

Qualitative research using interpersonal process recall interviews with oral examiners immediately following examination of an Medical Research Council General Practitioner (MRCGP) candidate.

SETTING

Summer 1999 sessions of the MRCGP examination in Edinburgh and London.

PARTICIPANTS

Twenty-six examiners in a convenience sample from the panel of Royal College of General Practitioners (RCGP) oral examiners.

RESULTS

Analysis of the transcripts revealed a three-stage process of decision-making consisting of a first impression, followed by a provisional grade and a final grade decision. The examiners used stem questions, exploratory questions and confirming questions during this process. Examiners produced lists of the attributes of successful and unsuccessful candidates, which resembled the grading guidelines provided by the examination committee. Some of the candidates' attributes which influenced the examiners' grading decisions related to personal qualities rather than knowledge or behaviours acquired in vocational training. When examiners were presented with the explanatory model arising from the analysis of the transcripts, they confirmed the validity of the observations.

CONCLUSIONS

Decision-making by examiners during oral examinations is a complex process involving initial impressions, hypothesis generation and hypothesis testing. Candidates' knowledge, attitudes and performance influence the final outcome of the examination. Interpersonal process recall is a useful tool for exploring professional communication.
