Background: General practitioners (GPs) should regularly review patients’ medications and, if necessary, deprescribe, as inappropriate polypharmacy may harm patients’ health. However, deprescribing can be challenging for physicians. This study investigates GPs’ deprescribing decisions in 31 countries. Methods: In this case vignette study, GPs were invited to participate in an online survey containing three clinical cases of oldest-old multimorbid patients with potentially inappropriate polypharmacy. Patients differed in terms of dependency in activities of daily living (ADL) and were presented with and without history of cardiovascular disease (CVD). For each case, we asked GPs if they would deprescribe in their usual practice. We calculated proportions of GPs who reported they would deprescribe and performed a multilevel logistic regression to examine the association between history of CVD and level of dependency on GPs’ deprescribing decisions. Results: Of 3,175 invited GPs, 54% responded (N = 1,706). The mean age was 50 years and 60% of respondents were female. Despite differences across GP characteristics, such as age (with older GPs being more likely to take deprescribing decisions), and across countries, overall more than 80% of GPs reported they would deprescribe the dosage of at least one medication in oldest-old patients (> 80 years) with polypharmacy irrespective of history of CVD. The odds of deprescribing was higher in patients with a higher level of dependency in ADL (OR =1.5, 95%CI 1.25 to 1.80) and absence of CVD (OR =3.04, 95%CI 2.58 to 3.57). Interpretation: The majority of GPs in this study were willing to deprescribe one or more medications in oldest-old multimorbid patients with polypharmacy. Willingness was higher in patients with increased dependency in ADL and lower in patients with CVD. publishersversion published

Introduction Common colds are the most frequently encountered disease worldwide and the most frequent reason for self-care. According to the cross-sectional European Common Colds study (COCO), patients use as many as 12 items on average for self-care. Little is known about the influence of discomfort and knowledge on self-care for common colds. Main objective To understand the influence of patients’ discomfort during a cold and their knowledge about the self-limited disease course on the use of self-care measures. Materials and methods This COCO analysis included 2,204 patients from 22 European primary care sites in 12 countries. Each site surveyed 120 consecutive adults with a 27-item questionnaire asking about patients’ self-care, subjective discomfort during a cold (discomfort: yes/no), and knowledge about the self-limited course (yes/no). Country-specific medians of the number of self-care items served as a cut-off to define high and low self-care use. Four groups were stratified based on discomfort (yes/no) and knowledge (yes/no). Results Participants’ mean age was 46.5 years, 61.7% were female; 36.3% lacked knowledge; 70.6% reported discomfort. The group has discomfort/no knowledge exhibited the highest mean item use (13.3), followed by has discomfort/has knowledge (11.9), no discomfort/no knowledge (11.1), and no discomfort/has knowledge (8.8). High use was associated with discomfort (OR 1.8; CI 1.5–2.2), female gender (OR 1.7; 1.4–2.0), chronic pain/arthritis (OR 1.6; 1.2–2.1), more years of education (OR 1.3; 1.1–1.6), age

Background: Strategies for the involvement of primary care in the management of patients with presumed or diagnosed dementia are heterogeneous across Europe. We wanted to explore attitudes of primary care physicians (PCPs) when managing dementia: i) the most popular cognitive tests ii) who had the right to initiate or continue cholinesterase inhibitor or memantine treatment and iii) therelationship between the permissiveness of these rules/guidelines and PCP’s approach in the dementia investigations and assessment.Methods: Key informant Survey. Setting: Primary care practices across 25 European countries. Subjects: Four hundred forty-five PCPs responded to a self-administered questionnaire. Two-step cluster analysis was performed using characteristics of the informants and the responses to the survey. Main outcome measures: Two by two contingency tables with odds ratios and 95% confidence intervals were used to assess the association between categorical variables. A multinomial logistic regression model was used to assess the association of multiple variables (age class, gender and perceived prescription rules) with the PCPs’ attitude of “trying to establish a diagnosis of dementia on their own”. Results: Discrepancies between rules/guidelines and attitudes to dementia management was found in many countries. There was a strong association between the authorization to prescribe dementia drugs and pursuing dementia diagnostic work-up (odds ratio, 3.45; 95% CI 2.28- 5.23). Conclusions: Differing regulations about who does what in dementia management seemed to affect PCP’s engagement in dementia investigations and assessment. PCPs who were allowed to prescribe dementia drugs also claimed higher engagement in dementia work-up than PCPs who were not allowed to prescribe.

OBJECTIVES Cancer survival and stage of disease at diagnosis and treatment vary widely across Europe. These differences may be partly due to variations in access to investigations and specialists. However, evidence to explain how different national health systems influence primary care practitioners' (PCPs') referral decisions is lacking.This study analyses health system factors potentially influencing PCPs' referral decision-making when consulting with patients who may have cancer, and how these vary between European countries. DESIGN Based on a content-validity consensus, a list of 45 items relating to a PCP's decisions to refer patients with potential cancer symptoms for further investigation was reduced to 20 items. An online questionnaire with the 20 items was answered by PCPs on a five-point Likert scale, indicating how much each item affected their own decision-making in patients that could have cancer. An exploratory factor analysis identified the factors underlying PCPs' referral decision-making. SETTING A primary care study; 25 participating centres in 20 European countries. PARTICIPANTS 1830 PCPs completed the survey. The median response rate for participating centres was 20.7%. OUTCOME MEASURES The factors derived from items related to PCPs' referral decision-making. Mean factor scores were produced for each country, allowing comparisons. RESULTS Factor analysis identified five underlying factors: PCPs' ability to refer; degree of direct patient access to secondary care; PCPs' perceptions of being under pressure; expectations of PCPs' role; and extent to which PCPs believe that quality comes before cost in their health systems. These accounted for 47.4% of the observed variance between individual responses. CONCLUSIONS Five healthcare system factors influencing PCPs' referral decision-making in 20 European countries were identified. The factors varied considerably between European countries. Knowledge of these factors could assist development of health service policies to produce better cancer outcomes, and inform future research to compare national cancer diagnostic pathways and outcomes.

Background: Despite the abundant literature on physical comorbidity, the full range of the concurrent somatic healthcare needs among individuals with schizophrenia has rarely been studied. Aims: This observational study aimed to assess the distressing somatic symptoms and needs for physical health interventions in outpatients with schizophrenia, and factors predicting those needs. Methods: A structured, comprehensive health examination was carried out, including a visit to a nurse and a general practitioner on 275 outpatients with schizophrenia. The required interventions were classified by type of disease. Logistic regression was used to assess the influence of sociodemographic factors, lifestyle, functional limitations, factors related to psychiatric disorder, and healthcare use on the need for interventions. Results: In total, 44.9% of the patients (mean age 44.9 years) reported somatic symptoms affecting daily life; 87.6% needed specific interventions for a disease or condition, most commonly for cardiovascular, dermatological, dental, ophthalmological, and gastrointestinal conditions, and for altered glucose homeostasis. Smoking and obesity predicted significantly a need of any intervention, but the predictors varied in each disease category. Strikingly, use of general practitioner services during the previous year did not reduce the need for interventions. Conclusions: Health examinations for outpatients with schizophrenia revealed numerous physical healthcare needs. The health examinations for patients with schizophrenia should contain a medical history taking and a physical examination, in addition to basic measurements and laboratory tests. Prevention and treatment of obesity and smoking should be given priority in order to diminish somatic comorbidities in schizophrenia.

OBJECTIVES We previously found large variations in general practitioner (GP) hypertension treatment probability in oldest-old (>80 years) between countries. We wanted to explore whether differences in country-specific cardiovascular disease (CVD) burden and life expectancy could explain the differences. DESIGN This is a survey study using case-vignettes of oldest-old patients with different comorbidities and blood pressure levels. An ecological multilevel model analysis was performed. SETTING GP respondents from European General Practice Research Network (EGPRN) countries, Brazil and New Zeeland. SUBJECTS This study included 2543 GPs from 29 countries. MAIN OUTCOME MEASURES GP treatment probability to start or not start antihypertensive treatment based on responses to case-vignettes; either low (80 years of age). • In this study including 1947 GPs from 29 countries, we found that a high country-specific cardiovascular disease (CVD) burden (i.e. myocardial infarction and/or stroke) was associated with a higher GP treatment probability in patients aged >80 years. • However, the association was modified by country-specific life expectancy at age 60. While there was a positive association for GPs in countries with a low life expectancy at age 60, there was no association in countries with a high life expectancy at age 60. • These findings help explaining some of the large variation seen in the decision as to whether or not to treat hypertension in the oldest-old.
