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.

Performance indicators for clinical practice management in primary care in Portugal: consensus from a Delphi study.

BACKGROUND: Performance indicators assessing the quality of medical care and linked to pay for performance may cause disagreement. Portuguese indicators included in recent health care reform are controversial. OBJECTIVES: To obtain consensus from opinion leaders in family medicine regarding the performance indicators for practice management used in the evaluation of Family Health Units in Portugal. METHODS: Eighty-nine specialists in primary care were invited to answer the following question in an online Delphi study: 'Which performance indicators should be assessed regarding the organization and management of clinical practice in primary care in Portugal?' A Likert scale was used to evaluate validity, reliability, feasibility and sensitivity to change. Twenty-seven experts participated in the second round and achieved a high degree of consensus. Eight categories were created for analysis. RESULTS: The experts suggested the use of existing indicators as well as new indicators. Thirty-nine indicators suggested by the experts are currently in use in Portugal. The assessment of the number of clinical acts performed, the number of administrative acts, and evaluation of the clinical demographic profile achieved a high degree of consensus. The expert panel suggested fifty new indicators. Five categories of these new indicators had a high degree of consensus, and three categories had a low degree of consensus. CONCLUSION: The expert panel recommended that performance indicators of practice management should first assess the quantity of clinical and administrative activities undertaken. These indicators must take into account the human and financial resources available to the clinic and its demographic context.

[Cervical cancer screening: target age bracket, screening frequency and screening method: review of recent evidence and comparison with the Portuguese performance indicator]. / Rastreio do câncer do colo do útero: limites etários, periodicidade e exame ideal: revisão da evidência recente e comparação com o indicador de desempenho avaliado em Portugal.

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]. / Grupo etário e periodicidade recomendados para a mamografia de rastreio: uma revisão sistemática.

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.

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.

Sintomas somatoformes em medicina de família: um estudo descritivo da incidência e evolução em uma unidade de saúde familiar de Portugal / Somatoform symptoms in family medicine: a descriptive study of incidence and outcome in a family health center in Portugal / Síntomas somatomorfos en medicina familiar: un estudio descriptivo de la incidencia y evolución en un centro de salud familiar de Portugal

Objetivo: O presente estudo objetivou avaliar a proporção de pacientes com queixas físicas, sem explicação orgânica, que foram identificados pelos médicos de família de uma unidade prestadora de cuidados de saúde primários de uma zona urbana de Portugal. Além disso, pretendeu-se avaliar a evolução deste tipo de queixas após 6 meses de observação. Métodos: Durante uma semana, oito médicos de família identificaram os pacientes que consultaram e que apresentaram queixas físicas para as quais não previam uma justificativa orgânica. Seis meses depois, os pacientes foram avaliados quanto à evolução dos seus sintomas. Resultados: Em 864 consultas, 73 (8%) pacientes apresentaram queixas físicas para as quais não havia previsão de explicação orgânica. Estes tinham maior probabilidade de terem depressão, ansiedade e síndrome do cólon irritável. Depois de 6 meses, apenas em 3 pacientes, foi identificada uma doença orgânica e 21 (33%) mantiveram-se com sintomas inalterados ou agravados. Conclusões: Os pacientes com sintomas físicos sem doença orgânica são frequentes nas consultas de medicina familiar. A maioria evolui para a remissão completa e o clínico tem uma pequena probabilidade de omitir um diagnóstico orgânic

Objective: This study aimed to estimate the proportion of patients with physical complaints, not attributable to organic causes, presented to family physicians working in an urban Portuguese primary care center and to evaluate the outcome of these clinical cases after 6 months of observation. Methods: For a week, eight family physicians were asked to identify consulting patients whose physical complaints did not seem to have organic causes. These patients were re-evaluated six months later to determine the outcome of their symptoms. Results: The eight physicians conducted 864 appointments during the study period and identified 73 patients (8%) with physical complaints for which no organic explanation was found. These patients were more likely to suffer from depression, anxiety, headache, and irritable bowel syndrome. After six months of follow-up, an organic cause was identified in only three of these patients, while 21 out of 73 patients (33%) had persistent unexplained symptoms. Conclusions: Patients with unexplained physical symptoms are frequently encountered in family practice. Most symptons resolve completely and clinicians have a small probability of missing a significant organic diagnosis in these patients.

Objetivo: El presente estudio buscó evaluar la proporción de pacientes con síntomas físicos sin explicación orgánica, identificados por los médicos de medicina familiar que trabajan en una unidad de atención primaria de la salud en una zona urbana de Portugal. Además se pretendió evaluar la evolución de este tipo de quejas después de 6 meses de observación. Métodos: Durante una semana, ocho médicos de medicina familiar identificaron los pacientes que refirieron problemas físicos para los cuales no se encontró justificativa orgánica. Seis meses después, los pacientes fueron evaluados con relación a la evolución de sus síntomas. Resultados: En 864 consultas, 73 (8%) eran pacientes con síntomas físicos para los que no se encontró explicación orgánica. Estos eran más propensos a tener depresión, ansiedad y síndrome de intestino irritable. Después de 6 meses, una enfermedad orgánica fue diagnosticada en sólo 3 pacientes y los síntomas se mantuvieron inalterados o sin agravarse en 21 pacientes (33%). Conclusiones: Los pacientes con síntomas físicos sin enfermedad orgánica son frecuentes en las consultas de medicina familiar. La mayor parte evoluciona hacia la remisión completa y el clínico tiene una pequeña probabilidad de omitir un diagnóstico orgánico.

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 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.

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.

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.

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.
