A volunteer-supported walking programme to improve physical function in older people with restricted mobility (the POWER Study): a randomised controlled trial.

BACKGROUND: Regular physical activity has multiple health benefits, especially in older people. Therefore, the World Health Organization recommends at least 2.5 h of moderate physical activity per week. The aim of the POWER Study was to investigate whether volunteer-assisted walking improves the physical performance and health of older people. METHODS: We approached people aged 65 years and older with restricted mobility due to physical limitations and asked them to participate in this multicentre randomised controlled trial. The recruitment took place in nursing homes and the community setting. Participants randomly assigned to the intervention group were accompanied by volunteer companions for a 30-50 min walk up to three times a week for 6 months. Participants in the control group received two lectures that included health-related topics. The primary endpoint was physical function as measured with the Short Physical Performance Battery (SPPB) at baseline and 6 and 12 months. The secondary and safety endpoints were quality of life (EQ-5D-5L), fear of falling (Falls Efficacy Scale), cognitive executive function (the Clock Drawing Test), falls, hospitalisations and death. RESULTS: The sample comprised 224 participants (79% female). We failed to show superiority of the intervention with regard to physical function (SPPB) or other health outcomes in the intention-to-treat analyses. However, additional exploratory analyses suggest benefits in those who undertook regular walks. The intervention appears to be safe regarding falls. CONCLUSIONS: Regular physical activity is essential to preserve function and to improve health and quality of life. Against the background of a smaller-than-planned sample size, resulting in low power, and the interference of the COVID-19 pandemic, we suggest that community based low-threshold interventions deserve further exploration. TRIAL REGISTRATION: The trial was registered with the German Clinical Trials Register ( www.germanctr.de ), with number DRKS00015188 on 31/08/2018.

Development and implementation of a treatment pathway to reduce coronary angiograms - lessons from a failure.

BACKGROUND: The rates of coronary angiograms (CA) and related procedures (percutaneous intervention [PCI]) are significantly higher in Germany than in other Organisation for Economic Co-ordination and Development (OECD) countries. The current guidelines recommend non-invasive diagnosis of coronary heart disease (CHD); CA should only have a limited role in choosing the appropriate revascularisation procedure. The aim of the present study was to explore whether improvements in guideline adherence can be achieved through the implementation of regional treatment pathways. We chose four regions of Germany with high utilisation of CAs for the study. Here we report the results of the concomitant qualitative study. METHODS: General practitioners and specialist physicians (cardiologists, hospital-based cardiologists, emergency physicians, radiologists and nuclear medicine specialists) caring for patients with suspected CHD were invited to develop regional treatment pathways. Four academic departments provided support for moderation, provision of materials, etc. The study team observed session discussions and took notes. After the development of the treatment pathways, 45 semi-structured interviews were conducted with the participating physicians. Interviews and field notes were transcribed verbatim and underwent qualitative content analysis. RESULTS: Pathway development received little support among the participants. Although consensus documents were produced, the results were unlikely to improve practice. The participants expressed very little commitment to change. Although this attempt clearly failed in all study regions, our experience provides relevant insights into the process of evidence appraisal and implementation. A lack of organisational skills, ignorance of current evidence and guidelines, and a lack of feedback regarding one's own clinical behaviour proved to be insurmountable. CA was still seen as the diagnostic gold standard by most interviewees. CONCLUSIONS: Oversupply and overutilisation can be assumed to be present in study regions but are not immediately perceived by clinicians. The problem is unlikely to be solved by regional collaborative initiatives; optimised resource planning within the health care system combined with appropriate economic incentives might best address these issues.

[Improving Postgraduate Medical Training In Germany: A Proposal]. / Ein Vorschlag zur Förderung der ärztlichen Weiterbildung im Kontext einer reformierten Krankenhausfinanzierung.

Postgraduate (vocational, residency) training in Germany is regulated by the Physicians' Chamber in each federal state. Although training requirements are specified in detail by regulatory documents, young doctors are left on their own to find training posts and suitable learning experiences. There are no programmes in place to support trainees nor to identify the need of the health care system regarding the composition of its medical workforce. Hospitals and practices pay salaries to physicians in training from funding obtained for services they provide. We propose a systematic and continuing process of identifying gaps in the workforce. Disciplines with a lack of qualified doctors will be supported by additional funds directed to practices and hospitals. Regional rotation schemes will coordinate and improve the quality of training. Apart from an administrative overhead, this system of regulation will not need additional resources because a limited part of current budgets will be explicitly channelled into salaries for trainees in specialties for which there is a higher need than into others.

Diffusion of a new drug among ambulatory physicians-The impact of patient pathways.

When drugs enter the market, physicians' prescribing behavior plays a crucial role in the diffusion process. Although regulations to foster economically efficient prescribing exist, physicians have some degree of freedom in choosing medication and are subject to various influencing factors. The aim of the present analysis is to investigate how interaction among patients and physicians affects the diffusion. We look at two different ways that patient pathways might influence physicians and examine these effects for Sacubitril/Valsartan (S/V), a new drug for patients with heart failure. Using administrative data from Germany, we identify physicians who prescribed S/V in the first 2 years of its availability. We apply survival models to estimate the impact of the patient-physician interaction on the physicians' adoption time. To this end, we determine whether individual physicians treated patients that had been prescribed S/V, and how many other physicians already prescribing S/V were connected in patient-sharing networks. Our main findings are that patients with a previous prescription seem to induce adoption by demanding repeat prescriptions. Moreover, patients establish connections between physicians that may lead to prescriptions for new patients. Our results therefore suggest that patient pathways play a significant role in the diffusion of a new drug.

Experiences of participants of a volunteer-supported walking intervention to improve physical function of nursing home residents - a mixed methods sub-study of the POWER-project.

BACKGROUND: Regular physical activity improves physical health and mental well-being and reduces the risk of falling in older adults. The randomized controlled "Prevention by lay-assisted Outdoor-Walking in the Elderly at Risk" POWER-study investigates whether volunteer-supported outdoor-walking improves physical function and quality of life in older people living independently or in nursing homes. This sub-study explores the experiences of older participants and volunteers in relation to their physical and psychosocial well-being as well as the challenges faced by both groups. A further aim was to explore volunteers' experience with people living in nursing homes during the first pandemic lockdown (spring 2020). METHODS: The sub-study was designed as mixed-methods approach consisting of 11 individual semi-structured guide-based interviews (nursing home residents), two focus group interviews (volunteers), and a cross-sectional questionnaire survey (volunteers). The interviews were audiotaped, transcribed verbatim, and analyzed by content analysis as described by Kuckartz. Topics addressed in the interviews were triangulated by means of a questionnaire. The quantitative data were analyzed using descriptive statistics. RESULTS: Participants' evaluation of the intervention was generally positive. Nursing home residents appreciated the social interaction associated with the assisted walking, which motivated them to take part regularly, provided a sense of safety, and caused pleasure on both sides. The impact on physical health status of the nursing home residents of this sub-study varied to a large degree as reported in interviews: in some cases, an improvement in physical performance, a decrease in physical complaints, and an improvement in gait or independence was reported. If not, reference was made to previous or sudden illnesses and the advanced age of the participants. Despite the COVID-19-lockdown and the associated restrictions, about 60% of contacts were still possible and participants planned to continue the assisted walks after the lockdown. CONCLUSION: Volunteers have a positive effect on the quality of life, mobility, and general health of nursing home residents. Even more than the improvement of physical performance, social interaction was seen as helpful. Despite their advanced age, the nursing home residents were curious and open to new contacts. When removing the identified barriers, it might be possible to integrate this program into the long-term everyday life of nursing homes.

Physicians' assessment of the Bavarian drug-expenditure control system: a qualitative study.

BACKGROUND: In 2014 a new system for drug expenditures, the Wirkstoffvereinbarung (WSV, English: Active substance agreement) was implemented in Bavaria. In pre-defined indication groups, economic prescription of medications shall be enabled based on the selection, quantity, and proportion of an individual drug. Ambulatory care physicians receive quarterly trend reports on their prescribing behavior. This study examines physicians' perceptions of the WSV. METHODS: Qualitative interviews (n = 20) and seven focus groups (n = 36) were conducted with ambulatory care physicians (e.g. general practitioners, cardiologists, pulmonologists). The methodology followed Qualitative Content Analysis. RESULTS: Physicians generally accepted the necessity of prescribing economically. The majority of them rated the WSV positively and better than the previous system. As an improvement, they especially named timely feedback in form of easily understandable trend reports, encouraging self-reflection as well as allowing early control options. Problems perceived were drug discount contracts that were strongly criticized as leading to patients mixing up medications. Some perceived constraints of therapeutic freedom. CONCLUSIONS: The implementation of the WSV is mostly viewed positively by physicians. The restrictions of therapeutic freedom partially perceived might be met by improved information on the reasons why some drugs are rated as less economical than others.

Identifying and Investigating Ambulatory Care Sequences Before Invasive Coronary Angiography.

BACKGROUND: The concept of care pathways is widely used to provide efficient, timely, and evidence-based medical care. Recently, the investigation of actual empirical patient pathways has gained attention. We demonstrate the usability of State Sequence Analysis (SSA), a data mining approach based on sequence clustering techniques, on comprehensive insurance claims data from Germany to identify empirical ambulatory care sequences. We investigate patients with coronary artery disease before invasive coronary angiography (CA) and compare identified patterns with guideline recommendations. This patient group is of particular interest due to high and regionally varying CA rates. METHODS: Events relevant for the care of coronary artery disease patients, namely physician consultations and medication prescriptions, are identified based on medical guidelines and combined to define states. State sequences are determined for 1.5 years before CA. Sequence similarity is defined for clustering, using optimal matching with theory-informed substitution costs. We visualize clusters, present descriptive statistics, and apply logistic regression to investigate the association of cluster membership with subsequent undesired care events. RESULTS: Five clusters are identified, the included patients differing with respect to morbidity, urbanity of residential area, and health care utilization. Clusters exhibit significant differences in the timing, structure, and extent of care before CA. When compared with guideline recommendations, 3 clusters show signs of care deficits. CONCLUSIONS: Our analyses demonstrate the potential of SSA for exploratory health care research. We show how SSA can be used on insurance claims data to identify, visualize, and investigate care patterns and their deviations from guideline recommendations.

Regional variation in coronary angiography rates: the association with supply factors and the role of indication: a spatial analysis.

BACKGROUND: Coronary angiographies (CAs) are among the most common diagnostic procedures carried out in German hospitals, and substantial regional differences in their frequency of use have been documented. Given the heterogeneity with regard to the expected benefits and the varying scope for discretion depending on the indication for the procedure, we hypothesized that the observed variation and the association of need and supply factors differs by indication for CA. METHODS: We investigated the correlation between supply factors and the regional rates of CAs in Germany while controlling for need using spatial-autoregressive error models (SARE) and spatial cross-regressive models with autoregressive errors (SCRARE). The overall rates of CAs and the rates in specific patient subgroups, namely, patients with and without myocardial infarction (MI), were calculated based on a comprehensive set of nationwide routine data from three statutory health insurances at the district level. RESULTS: Although little variation was found in cases with MI, considerable variation was seen in the overall cases and cases without MI. The SARE models revealed a positive association between the number of hospitals with a cardiac catheterization laboratory per 10,000 population and the rates of overall cases and cases without MI, whereas no such relationship existed in cases with MI. Additionally, an association between regional deprivation and the rates of CAs was found in cases with MI, but no such association was seen in cases without MI. CONCLUSIONS: The results supported the hypothesis that the relative association of need and supply factors differed by the indication for CA. Although the regional differences in the frequency of use of CAs can only be explained in part by the factors examined in our study, it offers insight into patient access to and the provision of CA services and can provide a platform for further local research.

Inductive foraging: patients taking the lead in diagnosis, a mixed-methods study.

BACKGROUND: Patient involvement in treatment decisions is widely accepted. Making a diagnosis, however, is still seen as a technical task mainly driven by physicians. Patients in this respect are perceived as passive providers of data. But, recent patient-centred concepts highlight the value of an active patient involvement in diagnosis. OBJECTIVE: We aim to reach a deeper understanding of how patients themselves contribute to the diagnostic process. METHODS: This is an observational study of patient consultations with their General Practitioner (GP) in 12 German practices. We performed a mixed-method qualitative and quantitative analysis of 134 primary care consultations. RESULTS: At the beginning of most consultations lies a phase where patients were invited to freely unfold their reason for encounter: This was named "inductive foraging" (IF). While patients actively present their complaints, GPs mainly listen and follow the presentation. This episode was found with every GP participating in this study. Ninety-one percent of consultations with diagnostic episodes were opened by IF. IF had a major contribution to the number of cues (diagnostic information) yielded in the diagnostic process. We illustrate a variety of tactics GPs make use of to invite, support, and terminate their patients in IF. CONCLUSION: IF was found to be a highly relevant strategy in the diagnostic process. Patient involvement through IF offered a major contribution of diagnostic cues. We hypothesize that a patient-centred approach improves diagnosis.

Making a diagnosis is a central part in medicine. Before advising treatments, physicians need to understand patients' complaints and ideally the reason for their symptoms. Generating an accurate diagnosis is often attributed to clinicians asking many specific questions and performing an array of tests. The patients' task in turn is passively answering "yes" or "no," or donating blood. In this study, we shed a different light on the phenomenon of diagnosis. We observed and recorded 295 primary care consultations. After each consultation, GPs were asked to reflect on their diagnostic thinking during the encounter. At the beginning of consultations, we witnessed a phase where patients were invited to freely report their complains and unfold their reason for encounter. Here, physicians mainly listened to their patients and motivated for further elaboration. We termed this phase "inductive foraging." GPs received the majority of diagnostic information (cues) during this phase. We therefore belief that an active patient involvement may improve diagnosis.

Educating physicians on strong opioids by descriptive versus simulated-experience formats: a randomized controlled trial.

BACKGROUND: Long-term prescriptions of strong opioids for chronic noncancer pain-which are not supported by scientific evidence-suggest miscalibrated risk perceptions among those who prescribe, dispense, and take opioids. Because risk perceptions and behaviors can differ depending on whether people learn about risks through description or experience, we investigated the effects of descriptive versus simulated-experience educative formats on physicians' risk perceptions of strong opioids and their prescription behavior for managing chronic noncancer pain. METHODS: Three hundred general practitioners and 300 pain specialists in Germany-enrolled separately in two independent exploratory randomized controlled online trials-were randomly assigned to either a descriptive format (fact box) or a simulated-experience format (interactive simulation). PRIMARY ENDPOINTS: Objective risk perception (numerical estimates of opioids' benefits and harms), actual prescriptions of seven therapy options for managing chronic pain. SECONDARY ENDPOINT: Implementation of intended prescriptions of seven therapy options for managing chronic pain. RESULTS: Both formats improved the proportion of correct numerical estimates of strong opioids' benefits and harms immediately after intervention, with no notable differences between formats. Compared to description, simulated experience led to significantly lower reported actual prescription rates for strong and/or weak opioids, and was more effective at increasing prescription rates for non-drug-based therapies (e.g., means of opioid reduction) from baseline to follow-up for both general practitioners and pain specialists. Simulated experience also resulted in a higher implementation of intended behavior for some drug-based and non-drug-based therapies. CONCLUSIONS: The two formats, which recruit different cognitive processes, may serve different risk-communication goals: If the goal is to improve exact risk perception, descriptive and simulated-experience formats are likely to be equally suitable. If, however, the goal is to boost less risky prescription habits, simulated experience may be the better choice.

[Prescribing behavior of Bavarian general practitioners at the inpatient-outpatient interface within the context of the Bavarian active substance agreement-qualitative results of the WirtMed Study]. / Verordnungsverhalten von bayerischen Hausärzt*innen an der stationär-ambulanten Schnittstelle vor dem Hintergrund der Bayerischen Wirkstoffvereinbarung ­ Qualitative Ergebnisse der WirtMed-Studie.

BACKGROUND AND OBJECTIVES: In 2014, the Association of Statutory Health Insurance Physicians of Bavaria introduced the active substance agreement (WSV) for the transparent control of pharmaceutical expenditure within the framework of the efficiency principle (§ 12 of the Fifth Book of the German Social Code [SGB V]). It replaced the prescribing target scheme. Regarding the role of the WSV, the article presents the reasons of the general practitioners (GPs) for or against a further prescription of drugs from the hospital. MATERIALS AND METHODS: In a qualitative study design, individual interviews (n = 18) and two focus groups (n = 10) were conducted with Bavarian GPs between November 2019 and March 2020 and evaluated according to qualitative content analysis. RESULTS: With the introduction of the WSV, recourse concerns decreased for GPs overall. Patient-oriented care and the professional correctness of therapy decisions are of great importance in prescribing, ahead of cost-effectiveness. Economic challenges arise with discharge medication, especially with the lead substance target of oral anticoagulants, the generic targets for antidiabetics, and for therapeutics for the cardiovascular system. Generally criticized are drug discount contracts, which often lead to drug changes after hospital discharge. There are individual reports of a "predominance" of hospital physicians when prescribing, which is contrary to their own economic actions as GPs. According to the GPs, there is a lack of cross-sectoral cost responsibility. CONCLUSIONS: In the view of GPs, a smooth interface transition is not yet available in the outpatient sector despite a framework agreement on discharge management and the new control system of the WSV. An economical supply of drugs continues to require political discussion across sectors, but also across federal states.

Delivering the unexpected-Information needs for PSA screening from Men's perspective: A qualitative study.

BACKGROUND: Making decisions about PSA screening tests is challenging, as it requires both knowledge of the possible benefits and harms of screening and an individual assessment of the patient's values. Our research explores how much and what information men perceive to be necessary with regard to screening for prostate cancer. OBJECTIVE: To explore men's information and associated needs for decision making in PSA testing. DESIGN: Qualitative interview study. SETTING AND PARTICIPANTS: We interviewed 32 men (aged 55-69) about their decision making on PSA screening following counselling with a Decision Aid at their GP's or urologist's practice in Germany. MAIN OUTCOME MEASURES: Men's expressed needs for decision making in PSA testing. METHODS: All interviews were transcribed verbatim and analysed by framework analysis. RESULTS: Comprehensive pre-screening counselling is needed. For the men in our study, information about test (in)accuracy, the benefit-harm balance and consequences of the test were relevant and surprising. Additional needs were for interpretation support, a take-home summary and time for deliberation. For several men, their physician's attitude was of interest. After being well-informed, most men felt empowered to make a preference-based decision on their own. DISCUSSION: Men were surprised by what they learned, especially regarding the accuracy and possible harms of screening. There is large variation in the breadth and depth of information needed, and some controversy regarding the consequences of testing. CONCLUSION AND PATIENT CONTRIBUTION: A core set of information should be offered before men make their first PSA screening decision. Information about biopsy and associated side-effects could follow in a short form, with details only on request. Knowledge about a high rate of false-positive test results beforehand might help men handle a suspicious test result.

A volunteer-supported walking programme to improve physical function in older people (the POWER Study): study protocol for a randomised controlled trial.

BACKGROUND: Currently 21% of the German population is older than 65 years. Above this age, the risk of suffering from chronic disease and mental disorders increases rapidly. Therefore, physical inactivity is one of the most important public health concerns among older people. To address this issue, we have conceptualised and evaluated a simple and low-threshold intervention, which requires only minimal demand on the participants, targeting older people with inadequate activity levels. The aim of the POWER Study is to investigate whether volunteer-supported outdoor-walking improves physical function and quality of life in older people. METHODS/DESIGN: In a randomised, controlled interventional superiority-trial, individuals older than 65 years of age living in the community or nursing homes will be randomised into two groups. The study will be conducted in two study centres with assessments at baseline, 6 and 12 months. The intervention group will participate in a supported physical activity intervention for 6 months. An assigned volunteer will visit them three times a week for an outdoor walk between 30 and 50 min, or equivalent indoor activity. Persons in the control group will be invited to two lectures covering topics related to health. Primary endpoint is the physical function measured by the Short Physical Performance Battery (SPPB) at baseline, after 6 and 12 months. Secondary and safety endpoints will be quality of life (EQ. 5D), fear of falling (Falls Efficacy Scale), physical activity (activity diary), cognitive executive function (clock drawing test), falls requiring medical attention, hospitalisation and death. Primary analysis will be carried out by intention to treat. DISCUSSION: We expect the intervention to improve the overall health status of the participants in a wide range of health-related outcomes. If effectiveness can be shown, the intervention will close an important gap in current services for older people. We will disseminate our experiences and results in the form of informational documents (training manual) to allow municipalities and health care organisations to implement a similar intervention.

Coughing children in family practice and primary care: a systematic review of prevalence, aetiology and prognosis.

BACKGROUND: For evidence-based decision making, primary care physicians need to have specific and reliable information on the pre-test probabilities of underlying diseases and a symptom's course. We performed a systematic review of symptom-evaluating studies in primary care, following three research questions: (1) What is the prevalence of the symptom cough in children consulting primary care physicians? (2) What are the underlying aetiologies of cough and the respective frequencies? (3) What is the prognosis of children with cough? METHODS: Following a pre-defined algorithm and independent double reviewer ratings we searched MEDLINE and EMBASE. All quantitative original research articles in English, French or German were included if they focused on unselected study populations of children consulting a primary care physician for cough. We used the random effects model for meta-analysis in subgroups, if justifiable in terms of heterogeneity. RESULTS: We identified 14 eligible studies on prevalence, five on aetiology and one on prognosis. Prevalence estimates varied between 4.7 and 23.3% of all reasons for an encounter, or up to estimates of 60% when related to patients or consultations. Cough in children is more frequent than in adults, with lowest prevalences in adolescents and in summer. Acute cough is mostly caused by upper respiratory tract infections (62.4%) and bronchitis (33.3%); subacute or chronic cough by recurrent respiratory tract infection (27.7%), asthma (up to 50.4% in cough persisting more than 3 weeks), and pertussis (37.2%). Potentially serious diseases like croup, pneumonia or tuberculosis are scarce. In children with subacute and chronic cough the total duration of cough ranged from 24 to 192 days. About 62.3% of children suffering from prolonged cough are still coughing two months after the beginning of symptoms. CONCLUSION: Cough is one of the most frequent reasons for an encounter in primary care. Our findings fit in with current guideline recommendations supporting a thoughtful wait-and-see approach in acute cough and a special awareness in chronic cough of the possibility of asthma and pertussis. Further evidence of aetiological pre-test probabilities is needed to assess the diagnostic gain based on patient history and clinical signs for differential diagnoses of cough in children.

Prevalence, aetiologies and prognosis of the symptom cough in primary care: a systematic review and meta-analysis.

BACKGROUND: Cough is a relevant reason for encounter in primary care. For evidence-based decision making, general practitioners need setting-specific knowledge about prevalences, pre-test probabilities, and prognosis. Accordingly, we performed a systematic review of symptom-evaluating studies evaluating cough as reason for encounter in primary care. METHODS: We conducted a search in MEDLINE and EMBASE. Eligibility criteria and methodological quality were assessed independently by two reviewers. We extracted data on prevalence, aetiologies and prognosis, and estimated the variation across studies. If justifiable in terms of heterogeneity, we performed a meta-analysis. RESULTS: We identified 21 eligible studies on prevalence, 12 on aetiology, and four on prognosis. Prevalence/incidence estimates were 3.8-4.2%/12.5% (Western primary care) and 10.3-13.8%/6.3-6.5% in Africa, Asia and South America. In Western countries the underlying diagnoses for acute cough or cough of all durations were respiratory tract infections (73-91.9%), influenza (6-15.2%), asthma (3.2-15%), laryngitis/tracheitis (3.6-9%), pneumonia (4.0-4.2%), COPD (0.5-3.3%), heart failure (0.3%), and suspected malignancy (0.2-1.8%). Median time for recovery was 9 to 11 days. Complete recovery was reported by 40.2- 67% of patients after two weeks, and by 79% after four weeks. About 21.1-35% of patients re-consulted; 0-1.3% of acute cough patients were hospitalized, none died. Evidence is missing concerning subacute and chronic cough. CONCLUSION: Prevalences and incidences of cough are high and show regional variation. Acute cough, mainly caused by respiratory tract infections, is usually self-limiting (supporting a "wait-and-see" strategy). We have no setting-specific evidence to support current guideline recommendations concerning subacute or chronic cough in Western primary care. Our study presents epidemiological data under non non-pandemic conditions. It will be interesting to compare these data to future research results of the post-pandemic era.

Generic instruments for drug discontinuation in primary care: A systematic review.

AIMS: The aim of this systematic review was to identify generic instruments for drug discontinuation in patients with polypharmacy in the primary care setting. METHODS: We systematically searched PubMed and EMBASE, 8 guideline databases (AWMF, NICE, NGC, SIGN, NHMRC, CPG, KCE), the Cochrane Library and grey literature (Google) in 2016 and 2017. Two independent researchers screened and analysed data. The drug discontinuation instruments of the included publications were described and classified. RESULTS: We identified 16 relevant publications. Here we found complex algorithms as well as instruments composed of distinct sequential steps. Two guidelines are constructed as electronic web-applications. Instruments revealed diverging emphases on the stages of deprescribing, i.e. preparation, drug evaluation, decision-making and implementation. Accordingly, 3 types of instruments emerged: general frameworks, detailed drug assessment tools and comprehensive discontinuation guidelines. CONCLUSION: Diverse generic instruments exist for different areas of applications in regard to drug discontinuation. However, there is still a need for practical and user-friendly tools that support physicians in communicational aspects, visualise trade-offs and also enhance patient involvement.

Regret among primary care physicians: a survey of diagnostic decisions.

BACKGROUND: Experienced and anticipated regret influence physicians' decision-making. In medicine, diagnostic decisions and diagnostic errors can have a severe impact on both patients and physicians. Little empirical research exists on regret experienced by physicians when they make diagnostic decisions in primary care that later prove inappropriate or incorrect. The aim of this study was to explore the experience of regret following diagnostic decisions in primary care. METHODS: In this qualitative study, we used an online questionnaire on a sample of German primary care physicians. We asked participants to report on cases in which the final diagnosis differed from their original opinion, and in which treatment was at the very least delayed, possibly resulting in harm to the patient. We asked about original and final diagnoses, illness trajectories, and the reactions of other physicians, patients and relatives. We used thematic analysis to assess the data, supported by MAXQDA 11 and Microsoft Excel 2016. RESULTS: 29 GPs described one case each (14 female/15 male patients, aged 1.5-80 years, response rate < 1%). In 26 of 29 cases, the final diagnosis was more serious than the original diagnosis. In two cases, the diagnoses were equally serious, and in one case less serious. Clinical trajectories and the reactions of patients and relatives differed widely. Although only one third of cases involved preventable harm to patients, the vast majority (27 of 29) of physicians expressed deep feelings of regret. CONCLUSION: Even if harm to patients is unavoidable, regret following diagnostic decisions can be devastating for clinicians, making them 'second victims'. Procedures and tools are needed to analyse cases involving undesirable diagnostic events, so that 'true' diagnostic errors, in which harm could have been prevented, can be distinguished from others. Further studies should also explore how physicians can be supported in dealing with such events in order to prevent them from practicing defensive medicine.

Professional roles of general practitioners, community pharmacists and specialist providers in collaborative medication deprescribing - a qualitative study.

BACKGROUND: Collaborative care approaches between general practitioners (GPs) and pharmacists have received international recognition for medication optimization and deprescribing efforts. Although specialist providers have been shown to influence deprescribing, their profession so far remains omitted from collaborative care approaches for medication optimization. Similarly, while explorative studies on role perception and collaboration between GPs and pharmacists grow, interaction with specialists for medication optimization is neglected. Our qualitative study therefore aims to explore GPs', community pharmacists' and specialist providers' role perceptions of deprescribing, and to identify interpersonal as well as structural factors that may influence collaborative medication optimization approaches. METHOD: Seven focus-group discussions with GPs, community pharmacists and community specialists were conducted in Hesse and Lower Saxony, Germany. The topic guide focused on views and experiences with deprescribing with special attention to inter-professional collaboration. We conducted conventional content analysis and conceptualized emerging themes using the Theoretical Domains Framework. RESULTS: Twenty-six GPs, four community pharmacists and three community specialists took part in the study. The main themes corresponded to the four domains 'Social/professional role and identity' (1), 'Social influences' (2), 'Reinforcement' (3) and ´Environmental context and resources' (4) which were further described by beliefs statements, that is inductively developed key messages. For (1), GPs emerged as central medication managers while pharmacists and specialists were assigned confined or subordinated tasks in deprescribing. Social influences (2) encompassed patients' trust in GPs as a support, while specialists and pharmacists were believed to threaten GPs' role and deprescribing attempts. Reinforcements (3) negatively affected GPs' and pharmacists' effort in medication optimization by social reprimand and lacking reward. Environmental context (4) impeded deprescribing efforts by deficient reimbursement and resources as well as fragmentation of care, while informational and gate-keeping resources remained underutilized. CONCLUSION: Understanding stakeholders' role perceptions on collaborative deprescribing is a prerequisite for joint approaches to medication management. We found that clear definition and dissemination of roles and responsibilities are premise for avoiding intergroup conflicts. Role performance and collaboration must further be supported by structural factors like adequate reimbursement, resources and a transparent continuity of care.

[Which Proportion of Prescriptions in Germany is Evidence Based?] / Welcher Anteil der Medikamentenverordnungen in Deutschland ist evidenzbasiert?

BACKGROUND: The provision of healthcare has to take into consideration evidence-based results from valid and relevant studies; this principle is included in German social laws. The prescribing assessment scheme (PAS) of the German National Association of Statutory Health Insurance Physicians contains a systematic appraisal of the benefit of drugs on the basis of their clinical evidence, their safety, and indications for their prescription. METHODS: We analysed nationwide prescription data of physicians that have contractual relationships with statutory health insurance funds in 2014. The drugs have been classified on the basis of their clinical evidence as "standard", "reserve" or "third level" medication. We report proportions of prescriptions in the first and third priority levels of the PAS in primary care, cardiology, and neurology/psychiatry as their prescriptions have a high correspondence with the PAS. RESULTS: The proportion in the first priority in primary care was more than two-thirds of the total prescriptions. The highest proportion in this category was observed in Bremen; the lowest proportions were found in the new federal states. In cardiology, the first priority was chosen in 54%, in neurology/psychiatry in about 41% of prescriptions (DDDs). The proportion of the third priority is with one-fifth highest in cardiology, with 16%, lowest in primary care; neurology/psychiatry takes a middle position with 17.7%. CONCLUSIONS: Prescriptions predominantly conformed with the first priority of the PAS. There were variations across disciplines and regions (federal states). The PAS offers an opportunity to connect quality and indication in the prescription process.

[Narratives help disseminate medical technologies: the case of coronary interventions]. / Mechanistische Narrative als Mittel der Dissemination: das Beispiel koronarer Technologien.

Medical technologies are often disseminated and used although evidence demonstrating their effectiveness and safety is missing. Percutaneous intervention (PCI) in stable coronary artery disease (CAD) is an example. This raises the question of how these technologies get disseminated and on which basis they are accepted by clinicians, patients, and the wider public.Studies investigating the communication between clinicians and patients show that simple narratives play a decisive role here. In this paper I discuss how narratives contribute to the dissemination of medical technologies. Communication within the profession, which includes medical education, also relies on narratives to a large degree. They have the following characteristics in common: 1) extreme simplification, 2) reduction to biological processes, 3) deterministic logic, and 4) strong moral message. These narratives are always biased; narratives dealing with interventions paint an overoptimistic picture of their effectiveness and safety. Although they represent "modern" technologies, their logic and purpose are akin to archaic myths.Presumably education and persuasion cannot eschew narratives completely. But health professionals, patients and the public should be aware of the inevitable bias that comes with narratives and their potential for manipulation.
