[Swiss recommendations for the check-up in the doctor's office]. / Schweizer Empfehlungen für den Check-up in der Arztpraxis.

Prevention and screening of diseases belong to the role of each primary care physician. Recommendations have been developed in the EviPrev programme, which brings together members of all five academic ambulatory general internal medicine centers in Switzerland (Lausanne, Bern, Geneva, Basel and Zürich). Several questions must be addressed before realising a prevention intervention: Do we have data demonstrating that early intervention or detection is effective? What are the efficacy and adverse effects of the intervention? What is the efficiency (cost-effectiveness) of the intervention? What are the patient's preferences concerning the intervention and its consequences? The recommendations aim at answering these questions independently, taking into account the Swiss context and integrating the patient's perspective in a shared decision-making encounter.

Simple functional performance tests and mortality in COPD.

Exercise tests are important to characterise chronic obstructive pulmonary disease patients and predict their prognosis, but are often not available outside of rehabilitation or research settings. Our aim was to assess the predictive performance of the sit-to-stand and handgrip strength tests. The prospective cohort study in Dutch and Swiss primary care settings included a broad spectrum of patients (n=409) with Global Initiative for Chronic Obstructive Lung Disease stages II to IV. To assess the association of the tests with outcomes, we used Cox proportional hazards (mortality), negative binomial (centrally adjudicated exacerbations) and mixed linear regression models (longitudinal health-related quality of life) while adjusting for age, sex and severity of disease. The sit-to-stand test was strongly (adjusted hazard ratio per five more repetitions of 0.58, 95% CI 0.40-0.85; p=0.004) and the handgrip strength test moderately strongly (0.84, 95% CI 0.72-1.00; p=0.04) associated with mortality. Both tests were also significantly associated with health-related quality of life but not with exacerbations. The sit-to-stand test alone was a stronger predictor of 2-year mortality (area under curve 0.78) than body mass index (0.52), forced expiratory volume in 1 s (0.61), dyspnoea (0.63) and handgrip strength (0.62). The sit-to-stand test may close an important gap in the evaluation of exercise capacity and prognosis of chronic obstructive pulmonary disease patients across practice settings.

A decision aid to rule out pneumonia and reduce unnecessary prescriptions of antibiotics in primary care patients with cough and fever.

BACKGROUND: Physicians fear missing cases of pneumonia and treat many patients with signs of respiratory infection unnecessarily with antibiotics. This is an avoidable cause for the increasing worldwide problem of antibiotic resistance. We developed a user-friendly decision aid to rule out pneumonia and thus reduce the rate of needless prescriptions of antibiotics. METHODS: This was a prospective cohort study in which we enrolled patients older than 18 years with a new or worsened cough and fever without serious co-morbidities. Physicians recorded results of a standardized medical history and physical examination. C-reactive protein was measured and chest radiographs were obtained. We used Classification and Regression Trees to derive the decision tool. RESULTS: A total of 621 consenting eligible patients were studied, 598 were attending a primary care facility, were 48 years on average and 50% were male. Radiographic signs for pneumonia were present in 127 (20.5%) of patients. Antibiotics were prescribed to 234 (48.3%) of patients without pneumonia. In patients with C-reactive protein values below 10 µg/ml or patients presenting with C-reactive protein between 11 and 50 µg/ml, but without dyspnoea and daily fever, pneumonia can be ruled out. By applying this rule in clinical practice antibiotic prescription could be reduced by 9.1% (95% confidence interval (CI): 6.4 to 11.8). CONCLUSIONS: Following validation and confirmation in new patient samples, this tool could help rule out pneumonia and be used to reduce unnecessary antibiotic prescriptions in patients presenting with cough and fever in primary care. The algorithm might be especially useful in those instances where taking a medical history and physical examination alone are inconclusive for ruling out pneumonia.

Walk-ins seeking treatment at an emergency department or general practitioner out-of-hours service: a cross-sectional comparison.

BACKGROUND: Emergency Departments (ED) in Switzerland are faced with increasing numbers of patients seeking non-urgent treatment. The high rate of walks-ins with conditions that may be treated in primary care has led to suggestions that those patients would best cared for in a community setting rather than in a hospital. Efficient reorganisation of emergency care tailored to patients needs requires information on the patient populations using the various emergency services currently available. The aim of this study is to evaluate the differences between the characteristics of walk-in patients seeking treatment at an ED and those of patients who use traditional out-of-hours GP (General Practitioner) services provided by a GP-Cooperative (GP-C). METHODS: In 2007 and 2009 data was collected covering all consecutive patient-doctor encounters at the ED of a hospital and all those occurring as a result of contacting a GP-C over two evaluation periods of one month each. Comparison was made between a GP-C and the ED of the Waid City Hospital in Zurich. Patient characteristics, time and source of referral, diagnostic interventions and mode of discharge were evaluated. Medical problems were classified according to the International Classification of Primary Care (ICPC-2). Patient characteristics were compared using non-parametric tests and multiple logistic regression analysis was applied to investigate independent determinants for contacting a GP-C or an ED. RESULTS: Overall a total of 2974 patient encounters were recorded. 1901 encounters were walk-ins and underwent further analysis (ED 1133, GP-C 768). Patients consulting the GP-C were significantly older (58.9 vs. 43.8 years), more often female (63.5 vs. 46.9%) and presented with non-injury related medical problems (93 vs. 55.6%) in comparison with patients at the ED. Independent determining factors for ED consultation were injury, male gender and younger age. Walk-in distribution in both settings was equal over a period of 24 hours and most common during daytime hours (65%).Outpatient care was predominant in both settings but significantly more so at the GP-C (79.9 vs. 85.7%). CONCLUSIONS: We observed substantial differences between the two emergency settings in a non gate-keeping health care system. Knowledge of the distribution of diagnoses, their therapy, of diagnostic measures and of the factors which determine the patients' choice of the ED or the GP-C is essential for the efficient allocation of resources and the reduction of costs.

Obesity management and continuing medical education in primary care: results of a Swiss survey.

BACKGROUND: The worldwide increase in obesity is becoming a major health concern. General practitioners (GPs) play a central role in managing obesity. We aimed to examine Swiss GPs self-reported practice in diagnosis and treatment of obesity with a special focus on the performance of waist measurement. METHODS: A structured self-reported questionnaire was mailed to 323 GPs recruited from four urban physician networks in Switzerland. Measures included professional experience, type of practice, obesity-related continuing medical education (CME) and practice in dealing with obesity such as waist measurement. We assessed the association between the performance of waist measurement and obesity-related CME by multivariate ordered logistic regression controlling for GP characteristics as potential confounders. RESULTS: A total of 187 GPs responded to the questionnaire. More than half of the GPs felt confident in managing obesity. The majority of the GPs (73%) spent less than 4 days in the last 5 years on obesity-related CME. More than half of GPs gave advice to reduce energy intakes (64%), intakes of high caloric and alcoholic drinks (56%) and to increase the physical activity (78%). Half of the GPs seldom performed waist measurement and documentation. The frequency of obesity-related CME was independently associated with the performance of waist measurement when controlled for GPs' characteristics by multivariate ordered logistic regression. CONCLUSIONS: The majority of GPs followed guideline recommendations promoting physical activity and dietary counselling. We observed a gap between the increasing evidence for waist circumference assessment as an important measure in obesity management and actual clinical practice. Our data indicated that specific obesity-related CME might help to reduce this gap.

Effect of Briefing on Acupuncture Treatment Outcome Expectations, Pain, and Adverse Side Effects Among Patients With Chronic Low Back Pain: A Randomized Clinical Trial.

Importance: In observational studies, patients' treatment outcome expectations have been associated with better outcomes (ie, a placebo response), whereas concerns about adverse side effects have been associated with an in increase in the negative effects of treatments (ie, a nocebo response). Some randomized trials have suggested that communication from clinicians could affect the treatment outcomes by changing patients' expectations. Objective: To investigate whether treatment outcome expectations and reported adverse side effects could be affected by different briefing contents before a minimal acupuncture treatment in patients with chronic low back pain (CLBP). Design, Setting, and Participants: This randomized single-blinded clinical trial was conducted among patients with CLBP at 1 outpatient clinic in Switzerland who had a pain intensity of at least 4 on a numeric rating scale from 0 to 10. Different recruitment channels were used to enroll patients. Data were collected from May 2016 to December 2017 and were analyzed from June to November 2018. Interventions: Patients were randomized to receive either a regular expectation briefing or a high expectation briefing (effectiveness) and either a regular adverse side effect briefing or an intense adverse side effect briefing (adverse side effect) in a 2 × 2 factorial design. The intervention (briefing sessions and written materials) was standardized and delivered before the acupuncture treatment, with additional booster informative emails provided during the 4-week, 8-session acupuncture course. Main Outcomes and Measures: The primary end point was the patients' expectations regarding the effectiveness of the acupuncture treatment (Expectation for Treatment Scale [ETS]) after the briefing and the subsequent pain intensity (numeric rating scale). The primary end point for the adverse side effect briefing was the adverse side effect score at the end of the acupuncture treatment, derived from session-by-session assessments of adverse side effects. Results: A total of 152 patients with CLBP (mean [SD] age, 39.54 [12.52] years; 100 [65.8%] women) were included. The estimated group difference (regular vs high) for the ETS was -0.16 (95% CI -0.81 to 0.50, P = .64), indicating no evidence for a difference between intervention groups. There was also no evidence for a difference in pain intensity at the end of the acupuncture treatment between the groups with different expectation briefings. The adverse side effects score in the group with the intense adverse side effect briefing were estimated to be 1.31 times higher (95% CI, 0.94 to 1.82; P = .11) than after a regular adverse side effect briefing, but the finding was not statistically significant. Conclusions and Relevance: In this study, suggestions regarding treatment benefits (placebo) and adverse side effects (nocebo) did not affect treatment expectations or adverse side effects. Information regarding adverse side effects might require more research to understand nocebo responses. Trial Registration: German Clinical Trials Register Identifier: DRKS00010191.

Assessment of Chronic Illness Care with the German version of the ACIC in different primary care settings in Switzerland.

BACKGROUND: In Switzerland the extent to which patients with chronic illnesses receive care congruent with the Chronic Care Model (CCM) is unknown. METHODS: According to guidelines we translated the Assessment of Chronic Illness Care (ACIC) into German (G-ACIC). We tested the instrument in different primary care settings and compared subscales with the original testing. RESULTS: Difficulties encountered during the translation process consisted in the difference of health care settings in Switzerland and USA. However initial testing showed the G-ACIC to be a suitable instrument. The average ACIC subscale scores in Swiss managed care (MC)-, group (GP)- and single handed practices (SP) were higher for MC practices than for group- and single handed practices: Organization of the healthcare delivery system: MC mean (m) = 6.80 (SD 1.55), GP m = 5.42 (SD 0.99), SP m = 4.60 (SD 2.07); community linkages: MC m = 4.19 (SD 1.47), GP m = 4.83 (SD 1.81), SP m = 3.10 (SD 2.12); self-management support: MC m = 4.96 (SD 1.13), GP m = 4.73 (SD 1.40), SP m = 4.43 (SD 1.34); decision support: MC m = 4.75 (SD 1.06); GP m = 4.20 (SD 0.87), SP m = 3.25 (SD 1.59); delivery system design: MC m = 5.98 (SD 1.61), GP m = 5.05 (SD 2.05), SP m = 3.86 (SD 1.51) and clinical information systems: MC m = 4.34 (SD = 2.49), GP m = 2.06 (SD 1.35), SP m = 3.20 (SD 1.57). CONCLUSIONS: The G-ACIC is applicable and useful for comparing different health care settings in German speaking countries. Managed care organizations seem to implement the different components of the CCM in a greater extend than group and single handed practices. However, much room exists for further improvement.

The provision of out-of-hours care and associated costs in an urban area of Switzerland: a cost description study.

BACKGROUND: In Switzerland, General Practitioners (GPs) play an important role for out-of-hours emergency care as one service option beside freely accessible and costly emergency departments of hospitals. The aim of this study was to evaluate the services provided and the economic consequences of a Swiss GP out-of-hours service. METHODS: GPs participating in the out-of-hours service in the city of Zurich collected data on medical problems (ICPC coding), mode of contact, mode of resource use and services provided (time units; diagnostics; treatments). From a health care insurance perspective, we assessed the association between total costs and its two components (basic costs: charges for time units and emergency surcharge; individual costs: charges for clinical examination, diagnostics and treatment in the discretion of the GP). RESULTS: 125 GPs collected data on 685 patient contacts. The most prevalent health problems were of respiratory (24%), musculoskeletal (13%) and digestive origin (12%). Home visits (61%) were the most common contact mode, followed by practice (25%) and telephone contacts (14%). 82% of patients could be treated by ambulatory care. In 20% of patients additional technical diagnostics, most often laboratory tests, were used. The mean total costs for one emergency patient contact were €144 (95%-CI: 137-151). The mode of contact was an important determinant of total costs (mean total costs for home visits: €176 [95%-CI: 168-184]; practice contact: €90 [95%-CI: 84-98]; telephone contact: €48 [95%-CI: 40-55]). Basic costs contributed 83% of total costs for home visits and 70% of total costs for practice contacts. Individual mean costs were similarly low for home visits (€30) and practice contacts (€27). Medical problems had no relevant influence on this cost pattern. CONCLUSIONS: GPs managed most emergency demand in their out-of-hours service by ambulatory care. They applied little diagnostic testing and basic care. Our findings are of relevance for policy makers even from other countries with different pricing policies. Policy makers should be interested in a reimbursement system promoting out-of-hours care run by GPs as one valuable service option.

Toward Standardized Monitoring of Patients With Chronic Diseases in Primary Care Using Electronic Medical Records: Development of a Tool by Adapted Delphi Procedure.

BACKGROUND: Long-term care for patients with chronic diseases poses a huge challenge in primary care. There are deficits in care, especially regarding monitoring and creating structured follow-ups. Appropriate electronic medical records (EMR) could support this, but so far, no generic evidence-based template exists. OBJECTIVE: The aim of this study is to develop an evidence-based standardized, generic template that improves the monitoring of patients with chronic conditions in primary care by means of an EMR. METHODS: We used an adapted Delphi procedure to evaluate a structured set of evidence-based monitoring indicators for 5 highly prevalent chronic diseases (ie, diabetes mellitus type 2, asthma, arterial hypertension, chronic heart failure, and osteoarthritis). We assessed the indicators' utility in practice and summarized them into a user-friendly layout. RESULTS: This multistep procedure resulted in a monitoring tool consisting of condensed sets of indicators, which were divided into sublayers to maximize ergonomics. A cockpit serves as an overview of fixed goals and a set of procedures to facilitate disease management. An additional tab contains information on nondisease-specific indicators such as allergies and vital signs. CONCLUSIONS: Our generic template systematically integrates the existing scientific evidence for the standardized long-term monitoring of chronic conditions. It contains a user-friendly and clinically sensible layout. This template can improve the care for patients with chronic diseases when using EMRs in primary care.

ICE COLD ERIC--International collaborative effort on chronic obstructive lung disease: exacerbation risk index cohorts--study protocol for an international COPD cohort study.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is a systemic disease; morbidity and mortality due to COPD are on the increase, and it has great impact on patients' lives. Most COPD patients are managed by general practitioners (GP). Too often, GPs base their initial assessment of patient's disease severity mainly on lung function. However, lung function correlates poorly with COPD-specific health-related quality of life and exacerbation frequency. A validated COPD disease risk index that better represents the clinical manifestations of COPD and is feasible in primary care seems to be useful. The objective of this study is to develop and validate a practical COPD disease risk index that predicts the clinical course of COPD in primary care patients with GOLD stages 2-4. METHODS/DESIGN: We will conduct 2 linked prospective cohort studies with COPD patients from GPs in Switzerland and the Netherlands. We will perform a baseline assessment including detailed patient history, questionnaires, lung function, history of exacerbations, measurement of exercise capacity and blood sampling. During the follow-up of at least 2 years, we will update the patients' profile by registering exacerbations, health-related quality of life and any changes in the use of medication. The primary outcome will be health-related quality of life. Secondary outcomes will be exacerbation frequency and mortality. Using multivariable regression analysis, we will identify the best combination of variables predicting these outcomes over one and two years and, depending on funding, even more years. DISCUSSION: Despite the diversity of clinical manifestations and available treatments, assessment and management today do not reflect the multifaceted character of the disease. This is in contrast to preventive cardiology where, nowadays, the treatment in primary care is based on patient-specific and fairly refined cardiovascular risk profile corresponding to differences in prognosis. After completion of this study, we will have a practical COPD-disease risk index that predicts the clinical course of COPD in primary care patients with GOLD stages 2-4. In a second step we will incorporate evidence-based treatment effects into this model, such that the instrument may guide physicians in selecting treatment based on the individual patients' prognosis.

Toward Standardized Monitoring of Patients With Chronic Diseases in Primary Care Using Electronic Medical Records: Systematic Review.

BACKGROUND: Long-term care for patients with chronic diseases poses a huge challenge in primary care. In particular, there is a deficit regarding monitoring and structured follow-up. Appropriate electronic medical records (EMRs) could help improving this but, so far, there are no evidence-based specifications concerning the indicators that should be monitored at regular intervals. OBJECTIVE: The aim was to identify and collect a set of evidence-based indicators that could be used for monitoring chronic conditions at regular intervals in primary care using EMRs. METHODS: We searched MEDLINE (Ovid), Embase (Elsevier), the Cochrane Library (Wiley), the reference lists of included studies and relevant reviews, and the content of clinical guidelines. We included primary studies and guidelines reporting about indicators that allow for the assessment of care and help monitor the status and process of disease for five chronic conditions, including type 2 diabetes mellitus, asthma, arterial hypertension, chronic heart failure, and osteoarthritis. RESULTS: The use of the term "monitoring" in terms of disease management and long-term care for patients with chronic diseases is not widely used in the literature. Nevertheless, we identified a substantial number of disease-specific indicators that can be used for routine monitoring of chronic diseases in primary care by means of EMRs. CONCLUSIONS: To our knowledge, this is the first systematic review summarizing the existing scientific evidence on the standardized long-term monitoring of chronic diseases using EMRs. In a second step, our extensive set of indicators will serve as a generic template for evaluating their usability by means of an adapted Delphi procedure. In a third step, the indicators will be summarized into a user-friendly EMR layout.

Chronic conditions and multimorbidity in a primary care population: a study in the Swiss Sentinel Surveillance Network (Sentinella).

OBJECTIVES: To provide estimates of the prevalence of chronic conditions in Swiss primary care. METHODS: In total, 175 general practitioners (GP) or pediatricians (PED) reporting to the Swiss Sentinel Surveillance Network collected morbidity data. RESULTS: In 26,853 patient contacts, mean (± SD) age was 55.8 ± 21.6 or 6.1 ± 5.7 years (in GPs vs. PEDs, respectively) and 47% were males. In GP patients, median Thurgau Morbidity Index was 2 (IQR 1-3). The median numbers of chronic conditions and permanently used prescribed drugs were 2 (0-5) and 2 (1-4), respectively; in PEDs medians were 0. Out of all patients, 16.7 and 7.0% of the PED patients were hospitalized during the previous year; patients cared by family/proxies or community nurses were hospitalized significantly more often than patients living in homes (50.1 vs. 35.4%, OR 1.41, p < 0.001). Out of patients over 80 years of age, 51.5% were care dependent and 45.5% of the patients over 90 years were living in homes for the elderly. CONCLUSIONS: In a representative sample of Swiss primary care patients, a substantial part shows multimorbidity with a high prevalence of chronic diseases, multiple drug treatment, and care dependency. These data may serve to be compared with other patient groups or other primary care systems.

Cognitive-behavioural treatment for weight loss in primary care: a prospective study.

QUESTIONS UNDER STUDY: Cognitive-behavioural treatment (CBT) is effective for weight loss in obese patients, but such programmes are difficult to implement in primary care. We assessed whether implementation of a community-based CBT weight loss programme for adults in routine care is feasible and prospectively assessed patient outcome. PATIENTS AND METHODS: The weight loss programme was provided by a network of Swiss general practitioners in cooperation with a community centre for health education. We chose a five-step strategy focusing on structure of care rather than primarily addressing individual physician behaviour. A multidisciplinary core group of trained CBT instructors acted as the central element of the programme. Overweight and obese adults from the community (BMI >25 kg/m2) were included. We used a patient perspective to report the impact on delivery of care and assessed weight change of consecutive participants prospectively with a follow-up of 12 months. RESULTS: Twenty-eight courses, with 16 group meetings each, were initiated over a period of 3 years. 44 of 110 network physicians referred patients to the programme. 147 of 191 study participants were monitored for one year (attrition rate: 23%). Median weight loss after 12 months for 147 completers was 4 kg (IQR: 1-7 kg; intention-to-treat analysis for 191 participants: 2 kg, IQR: 0-5 kg). CONCLUSIONS: The programme produced a clinically meaningful weight loss in our participants, with a relatively low attrition rate. Implementation of an easily accessible CBT programme for weight loss in daily routine primary care is feasible.

Barriers to apply cardiovascular prediction rules in primary care: a postal survey.

BACKGROUND: Although cardiovascular prediction rules are recommended by guidelines to evaluate global cardiovascular risk for primary prevention, they are rarely used in primary care. Little is known about barriers for application. The objective of this study was to evaluate barriers impeding the application of cardiovascular prediction rules in primary prevention. METHODS: We performed a postal survey among general physicians in two Swiss Cantons by a purpose designed questionnaire. RESULTS: 356 of 772 dispatched questionnaires were returned (response rate 49.3%). About three quarters (74%) of general physicians rarely or never use cardiovascular prediction rules. Most often stated barriers to apply prediction rules among rarely- or never-users are doubts concerning over-simplification of risk assessment using these instruments (58%) and potential risk of (medical) over-treatment (54%). 57% report that the numerical information resulting from prediction rules is often not helpful for decision-making in practice. CONCLUSION: If regular application of cardiovascular prediction rules in primary care is in demand additional interventions are needed to increase acceptance of these tools for patient management among general physicians.

Medication incidents in primary care medicine: a prospective study in the Swiss Sentinel Surveillance Network (Sentinella).

OBJECTIVES: To describe the type, frequency, seasonal and regional distribution of medication incidents in primary care in Switzerland and to elucidate possible risk factors for medication incidents. DESIGN: Prospective surveillance study. SETTING: Swiss primary healthcare, Swiss Sentinel Surveillance Network. PARTICIPANTS: Patients with drug treatment who experienced any erroneous event related to the medication process and interfering with normal treatment course, as judged by their physician. The 180 physicians in the study were general practitioners or paediatricians participating in the Swiss Federal Sentinel reporting system in 2015. OUTCOMES: Primary: medication incidents; secondary: potential risk factors like age, gender, polymedication, morbidity, care-dependency, previous hospitalisation. RESULTS: The mean rates of detected medication incidents were 2.07 per general practitioner per year (46.5 per 1 00 000 contacts) and 0.15 per paediatrician per year (2.8 per 1 00 000 contacts), respectively. The following factors were associated with medication incidents (OR, 95% CI): higher age 1.004 per year (1.001; 1.006), care by community nurse 1.458 (1.025; 2.073) and care by an institution 1.802 (1.399; 2.323), chronic conditions 1.052 (1.029; 1.075) per condition, medications 1.052 (1.030; 1.074) per medication, as well as Thurgau Morbidity Index for stage 4: 1.292 (1.004; 1.662), stage 5: 1.420 (1.078; 1.868) and stage 6: 1.680 (1.178; 2.396), respectively. Most cases were linked to an incorrect dosage for a given patient, while prescription of an erroneous medication was the second most common error. CONCLUSIONS: Medication incidents are common in adult primary care, whereas they rarely occur in paediatrics. Older and multimorbid patients are at a particularly high risk for medication incidents. Reasons for medication incidents are diverse but often seem to be linked to communication problems.

Primary care in Switzerland--no longer attractive for young physicians?

BACKGROUND AND OBJECTIVES: A trend away from primary care (PC) to other specialties has been noted in Switzerland, as well as in the health-care systems of many other Western countries. The objective of the present study was to ascertain how many third-year residents graduating in 2001/02 from medical schools in German-speaking Switzerland wanted to become PC physicians (PCPs), whether this career goal was continuously followed, and how many subjects switched to or away from PC during residency. METHODS: Data reported are from the third assessment of the longitudinal Swiss physicians' career development study, begun in 2001. In 2005, at the third assessment, 515 residents (53.8% females, 46.2% males) were asked what specialty qualifications and career goals they aspired to. In addition, participants' socio-demographic, personality, and career-related characteristics as well as their life goals were addressed. RESULTS: Of n = 515 (total sample) third-year residents, 81 had not yet decided on the medical field in which they wished to specialise, while 434 had made this decision. Of the latter, only 42 (9.7%) aspired to become PCPs. Twelve of the 42 future PCPs consistently mentioned PC as a career goal from graduation throughout residency. The other 30 subjects only decided on PC during the course of their residencies. A switch away from PC was also noted in the case of 19 subjects who on graduation or after the first year of residency aspired to become PCPs, but abandoned this goal after three years of residency. Future PCPs differ from those pursuing other specialties in terms of personal and career-related characteristics, as well as in their life goals, insofar as they are less career-orientated and regard having more time outside work a priority. There are few gender-based differences between female and male future PCPs. CONCLUSION: Primary care seems to hold little attraction as a career goal for young physicians. Residency experiences would seem to have more of an effect on choice of specialty than teaching experiences during medical school. The percentage of subjects qualifying in PC is far too low to fill the need for the future generation of PCPs. In addition to efforts to incorporate PC issues into medical school curricula, structured residency programs should be established to promote PC.

The Inaccuracy of Patient Recall for COPD Exacerbation Rate Estimation and Its Implications: Results from Central Adjudication.

BACKGROUND: COPD exacerbation incidence rates are often ascertained retrospectively through patient recall and self-reports. We compared exacerbation ascertainment through patient self-reports and single-physician chart review to central adjudication by a committee and explored determinants and consequences of misclassification. METHODS: Self-reported exacerbations (event-based definition) in 409 primary care patients with COPD participating in the International Collaborative Effort on Chronic Obstructive Lung Disease: Exacerbation Risk Index Cohorts (ICE COLD ERIC) cohort were ascertained every 6 months over 3 years. Exacerbations were adjudicated by single experienced physicians and an adjudication committee who had information from patient charts. We assessed the accuracy (sensitivities and specificities) of self-reports and single-physician chart review against a central adjudication committee (AC) (reference standard). We used multinomial logistic regression and bootstrap stability analyses to explore determinants of misclassifications. RESULTS: The AC identified 648 exacerbations, corresponding to an incidence rate of 0.60 ± 0.83 exacerbations/patient-year and a cumulative incidence proportion of 58.9%. Patients self-reported 841 exacerbations (incidence rate, 0.75 ± 1.01; incidence proportion, 59.7%). The sensitivity and specificity of self-reports were 84% and 76%, respectively, those of single-physician chart review were between 89% and 96% and 87% and 99%, respectively. The multinomial regression model and bootstrap selection showed that having experienced more exacerbations was the only factor consistently associated with underreporting and overreporting of exacerbations (underreporters: relative risk ratio [RRR], 2.16; 95% CI, 1.76-2.65 and overreporters: RRR, 1.67; 95% CI, 1.39-2.00). CONCLUSIONS: Patient 6-month recall of exacerbation events are inaccurate. This may lead to inaccurate estimates of incidence measures and underestimation of treatment effects. The use of multiple data sources combined with event adjudication could substantially reduce sample size requirements and possibly cost of studies.

Medication incidents in primary care medicine: protocol of a study by the Swiss Federal Sentinel Reporting System.

BACKGROUND/RATIONALE: Patient safety is a major concern in healthcare systems worldwide. Although most safety research has been conducted in the inpatient setting, evidence indicates that medical errors and adverse events are a threat to patients in the primary care setting as well. Since information about the frequency and outcomes of safety incidents in primary care is required, the goals of this study are to describe the type, frequency, seasonal and regional distribution of medication incidents in primary care in Switzerland and to elucidate possible risk factors for medication incidents. STUDY DESIGN AND SETTING: We will conduct a prospective surveillance study to identify cases of medication incidents among primary care patients in Switzerland over the course of the year 2015. PARTICIPANTS: Patients undergoing drug treatment by 167 general practitioners or paediatricians reporting to the Swiss Federal Sentinel Reporting System. INCLUSION CRITERIA: Any erroneous event, as defined by the physician, related to the medication process and interfering with normal treatment course. EXCLUSION CRITERIA: Lack of treatment effect, adverse drug reactions or drug-drug or drug-disease interactions without detectable treatment error. PRIMARY OUTCOME: Medication incidents. RISK FACTORS: Age, gender, polymedication, morbidity, care dependency, hospitalisation. STATISTICAL ANALYSIS: Descriptive statistics to assess type, frequency, seasonal and regional distribution of medication incidents and logistic regression to assess their association with potential risk factors. Estimated sample size: 500 medication incidents. LIMITATIONS: We will take into account under-reporting and selective reporting among others as potential sources of bias or imprecision when interpreting the results. ETHICS AND DISSEMINATION: No formal request was necessary because of fully anonymised data. The results will be published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT0229537.

No association of 25-hydroxyvitamin D with exacerbations in primary care patients with COPD.

BACKGROUND: Cross-sectional studies suggest an association of 25-hydroxyvitamin D with exacerbations in patients with COPD, but longitudinal evidence from cohort studies is scarce. The aim of this study was to assess the association of serum 25-hydroxyvitamin D with exacerbations and mortality in primary care patients with COPD. METHODS: In the main analysis, we included 356 patients with COPD (GOLD [Global Initiative for Chronic Obstructive Lung Disease] stages II-IV, free from exacerbations for ≥ 4 weeks) from a prospective cohort study in Dutch and Swiss primary care settings. We used negative binomial and Cox regression to assess the association of 25-hydroxyvitamin D with (centrally adjudicated) exacerbations and mortality, respectively. RESULTS: Baseline mean ± SD serum 25-hydroxyvitamin D concentration was 15.5 ± 8.9 ng/dL, and 274 patients (77.0%) had 25-hydroxyvitamin D deficiency (< 20 ng/dL). Compared with patients with severe 25-hydroxyvitamin D deficiency (< 10 ng/dL, n = 106 [29.8%]), patients with moderately deficient (10-19.99 ng/dL, n = 168 [47.2%]) and insufficient (20-29.99 ng/dL, n = 58 [16.3%]) concentrations had the same risk for exacerbations (incidence rate ratio, 1.01 [95% CI, 0.77-1.57] vs 1.00 [95% CI, 0.62-1.61], respectively). In patients with desirable concentrations (> 30 ng/dL, n = 24 [6.7%]), the risk was lower, although not significantly (incidence rate ratio, 0.72 [95% CI, 0.37-1.42]). In patients taking vitamin D supplements, using different cutoffs for 25-hydroxyvitamin D or competing risk models did not materially change the results. We did not find a statistically significant association of 25-hydroxyvitamin D concentration with mortality. CONCLUSIONS: This longitudinal study in a real-world COPD population that carefully minimized misclassification of exacerbations and the influence of confounding did not show an association of 25-hydroxyvitamin D with exacerbations and mortality.

Prediction of COPD-specific health-related quality of life in primary care COPD patients: a prospective cohort study.

BACKGROUND: Health-related quality of life (HRQL) is an important patient-reported outcome for chronic obstructive pulmonary disease (COPD). AIM: We developed models predicting chronic respiratory questionnaire (CRQ) dyspnoea, fatigue, emotional function, mastery and overall HRQL at 6 and 24 months using predictors easily available in primary care. METHODS: We used the "least absolute shrinkage and selection operator" (lasso) method to build the models and assessed their predictive performance. RESULTS: were displayed using nomograms. RESULTS: For each domain-specific CRQ outcome, the corresponding score at baseline was the best predictor. Depending on the domain, these predictions could be improved by adding one to six other predictors, such as the other domain-specific CRQ scores, health status and depression score. To predict overall HRQL, fatigue and dyspnoea scores were the best predictors. Predicted and observed values were on average the same, indicating good calibration. Explained variance ranged from 0.23 to 0.58, indicating good discrimination. CONCLUSIONS: To predict COPD-specific HRQL in primary care COPD patients, previous HRQL was the best predictor in our models. Asking patients explicitly about dyspnoea, fatigue, depression and how they cope with COPD provides additional important information about future HRQL whereas FEV1 or other commonly used predictors add little to the prediction of HRQL.
