Objectives: The aim of our study was to compare the results of endoscopy and manometry with regard to the presence and longitudinal size of hiatal hernias using a cohort of patients with PPI-refractory reflux symptoms. In addition, we aimed to investigate the clinical relevance of hiatal hernias and their size in relation to the occurrence of GERD.

Methods: Five hundred patients with suspected GERD due to typical reflux symptoms (heartburn and regurgitation) and inadequate response to PPI therapy underwent standardized screening at a reflux center.

Background: The number of patients with proton pump inhibitor (PPI)-refractory reflux symptoms is underestimated since many patients resign after an unsuccessful therapy attempt. Thus, it would be useful having a non-invasive tool that can help identify true gastroesophageal reflux disease (GERD) patients in order to manage them early and properly. The GerdQ is a validated tool developed for this purpose but its applicability in PPI-refractory patients has not yet been investigated.

Background: Burnout in the field of gastroenterology is an under-researched phenomenon. So far, only a few studies have dealt with this topic. There are large geographical variations in burnout rates with 16-20% of gastroenterologists in Mexico and Germany being at risk or having burnout, 30-40% in the United Kingdom, and 50-55% in South Korea, Canada, and the USA.

International guidelines recommend to inform men about the benefits and harms of prostate specific antigen (PSA) based early detection of prostate cancer. This study investigates the influence of a transactional decision aid (DA) or cost compensation (CC) for a PSA test on the decisional behaviour of men. Prospective, cluster-randomised trial to compare two interventions in a 2 × 2 factorial design: DA versus counselling as usual, and CC versus noCC for PSA-testing.

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.

There is evidence that intake of proton pump inhibitors (PPI) increases the risk for spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis. However, data regarding the impact of PPI intake on occurrence of infections other than SBP are still lacking.We hypothesized that PPI use is associated with a higher rate of infections other than SBP in patients with liver cirrhosis.

Background: The ongoing digitalization in health care is enabling patients to receive treatment via telemedical technologies, such as video consultation (VC), which are increasingly being used by general practitioners. Rural areas in particular exhibit a rapidly aging population, with an increase in associated health issues, whereas the level of attraction for working in those regions is decreasing for young physicians. Integrating telemedical approaches in treating patients can help lessen the professional workload and counteract the trend toward the spatial undersupply in many countries.

Background: Burnout is known to have detrimental effects on healthcare staff with regard to both personal and occupational matters. The association between burnout symptoms and work satisfaction in endoscopy nursing staff in Germany has not been studied previously. We aimed to investigate the association between work satisfaction and risk of burnout in endoscopy nursing staff in Germany and to extract predictors for burnout in the area of work satisfaction, which can inform the design of future interventions.

Objectives: We examined the relationship between the initial treatment of acute lower and upper tract respiratory infections with phytopharmaceuticals and the duration of the disease as well as between the initial treatment and the use of antibiotics in the further course of the disease.

Method: Outpatients from the IMS® Disease Analyzer database with diagnoses of acute respiratory infections between January 2015 and March 2019 were observed for 30 days. Patients who had been prescribed phytopharmaceuticals on the day of their diagnosis were matched with controls who had not received such prescriptions by treating practice, diagnosis, age, sex, insurance status, index year, and Charlson comorbidity score.

Background: Shortage of general practitioners (GPs), especially in rural areas, is an increasing problem for the German healthcare system. Different approaches are pursued to counteract this development. The study HaMEdSi (Hausärzte (GPs) for Medical Education in Siegen-Wittgenstein) among other things examines the occupational perspectives of the GPs depending on their surgeries' characteristics and draws a realistic picture of how primary care in the region of Siegen-Wittgenstein, representative for many rural regions, will develop over the next few years.

Background: Etiological factors, such as a malignant disease, in young stroke patients are often neglected. Therefore, in this study, we aimed to investigate the risk of developing cancer in young stroke survivors.

Methods: The current case-control study sample included patients who received an initial ischemic stroke diagnosis documented in the Disease Analyzer database (IQVIA), which compiles data such as risk factors, drug prescriptions, and diagnoses obtained from general practitioners and specialists.

Background: Shared decision-making is a well-established approach to increasing patient participation in medical decisions. Increasingly, using lifetime-risk or time-to-event (TTE) formats has been suggested, as these might have advantages in comparison with a 10-year risk prognosis, particularly for younger patients, whose lifetime risk for some events may be considerably greater than their 10-year risk. In this study, a randomized trial, the most popular 10-year risk illustration in the decision-aid software Arriba (emoticons), is compared with a newly developed TTE illustration, which is based on a Markov model.

Background: The establishment of a medical education program in the rural area of Siegen is planned to be the first step against a shortage of physicians in this region. General practitioners (GPs) will be extensively involved in this program as Family Medicine (Allgemeinmedizin) will become a core subject in the curriculum nationwide. Based on this situation we aim to figure out GPs motivation to participate in medical education.

Background: An increasing number of general practitioners (GPs) are not satisfied with their working conditions and are at risk of developing burnout symptoms. As family medicine is becoming a major subject within the medical curriculum in Germany, practicing GPs need to meet higher demands in the future, ie, treating patients and taking part in the education of medical students. Accordingly, we aimed to determine GPs' work satisfaction and risk of burnout.

The shortage of general practitioners (GPs) in Germany has become a relevant problem. Therefore, it is important to find the determinants that make primary care more attractive, and which support GPs remaining in practice. Our aim in this exploratory study was to search for relevant GP subgroups and their characteristics in order to find starting points for improvements or interventions.

Several biases can occur when performing economic evaluations (EE) and it is important for researchers to minimize these biases, as they can significantly affect economic outcomes. This review aims, firstly, to identify biases that can occur in model-based EE and to illustrate their impact on economic outcomes and, secondly, to present a checklist for assessing the overall risk of bias in EE. Eleven biases that can occur in model-based studies were identified through a scoping review, scrutiny of systematic reviews, the authors' own experiences and discussions with experts.

There has been a debate on whether cost-effectiveness analysis should consider the cost of consumption and leisure time activities when using the quality-adjusted life year as a measure of health outcome under a societal perspective. The purpose of this study was to investigate whether the effects of ill health on consumptive activities are spontaneously considered in a health state valuation exercise and how much this matters. The survey enrolled patients with inflammatory bowel disease in Germany (n = 104).
