Aims Three randomized trials of implantable cardioverter defibrillator (ICD) therapy vs medical treatment for the prevention of death in survivors of ventricular fibrillation or sustained ventricular tachycardia have been reported with what might appear to be different results. The present analysis was performed to obtain the most precise estimate of the efficacy of the ICD, compared to amiodarone, for prolonging survival in patients with malignant ventricular arrhythmia.Methods and Results Individual patient data from the Antiarrhythmics vs Implantable Defibrillator (AVID) study, the Cardiac Arrest Study Hamburg (CASH) and the Canadian Implantable Defibrillator Study (CIDS) were merged into a master database according to a pre-specified protocol. Proportional hazard modelling of individual patient data was used to estimate hazard ratios and to investigate subgroup interactions. Fixed effect meta-analysis techniques were also used to evaluate treatment effects and to assess heterogeneity across studies. The classic fixed effects meta-analysis showed that the estimates of ICD benefit from the three studies were consistent with each other (P heterogeneity=0·306). It also showed a significant reduction in death from any cause with the ICD; with a summary hazard ratio (ICD:amiodarone) of 0·72 (95% confidence interval 0·60, 0·87;P=0·0006). For the outcome of arrhythmic death, the hazard ratio was 0·50 (95% confidence interval 0·37, 0·67;P<0·0001). Survival was extended by a mean of 4·4 months by the ICD over a follow-up period of 6 years. Patients with left ventricular ejection fraction ≤35% derived significantly more benefit from ICD therapy than those with better preserved left ventricular function. Patients treated before the availability of non-thoracotomy ICD implants derived significantly less benefit from ICD therapy than those treated in the non-thoracotomy era.Conclusion Results from the three trials of the ICD vs amiodarone are consistent with each other. There is a 28% reduction in the relative risk of death with the ICD that is due almost entirely to a 50% reduction in arrhythmic death. [ABSTRACT FROM PUBLISHER]

Background: Professional qualification as a doctor of medicine includes completion of medical studies and residency. Data on the real duration of residency are currently not assessed systematically in Germany., Objectives: Our study aimed to analyze data on the real length of residency under consideration of area of expertise (specialization), part-time working, grades after school and medical studies, gender, and parenthood of the physicians in residency., Material and Methods: The KarMed Study's database consists of annual postal surveys throughout the entire residency of medical students, beginning with their "Practical Year" in 2008/2009 until 2019. The study analyzed data six and ten years within this residency period., Results: The majority of the residents was capable of finishing their residency within the minimal time. One significant effect on actual duration of residency was the subject choice. One-third of the female residents had not yet finished their residency after ten years. Partenhood had a significant effect on female residents, but not on male residents. A regression analysis showed (R²corr=0.03, p<0.001) that the duration of residency was associated with the grade received after studying (β=0.30). Male residents were more satisfied with the overall residency then female residents., Discussion: Structural improvement in postgraduate training needs to be adjusted in terms of parental status. Prospective studies should take the selection process of universities into account and examine its association with the time required to complete residency., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Background: In Germany, homeless people are entitled to health care within the regular health care system. However, due to their specific living conditions they make little use of these services. In 2013, three Medical centres for the homeless (MCH) were opened in Hamburg to provide general health care. This study aims to analyse the consultation reasons and diagnoses prevalent among the homeless in comparison to regular primary care patients. It also examines the means and obstacles of integrating the homeless into Germany's regular health care system., Methods: From 2013 to 2014, routine medical data of all patients of the MCH consenting to participate in the study were analysed descriptively, in particular consultation reasons (categorised by ICPC-2), ICD-10 diagnoses and data on health insurance status and the use of the regular health care system. Consultation reasons and diagnoses of homeless patients were compared descriptively with data from regular general practices. Additionally, anonymous data on patient numbers, gender and insurance status was exported from the MCH's software and analysed descriptively for the years 2013 to 2020., Results: A total of 840 homeless patients in 2013 and 2014 gave consent to the evaluation of consultation reasons and diagnoses. The most frequent consultation reasons in the MCH in 2013 were skin conditions (24%), musculoskeletal conditions (16%) and psychological disorders (14%), in GP practices these were musculoskeletal conditions (22%), conditions affecting the digestive system (14%) and skin conditions (12%). Essential (primary) hypertension, diabetes mellitus type 2 and back pain are among the top-10-diagnoses in GP practices, as well as in MCH. With regard to the other top-10-diagnoses, there are clear differences between GP practices and MCH: "Psychological behavioural disorder due to alcohol" and diagnoses in connection with trauma, skin infections and acute respiratory infections stand out in MCH. 35% of the homeless patients reported a lack of health insurance as the reason for "not making use of" the regular health care system, while 10% reported they were unable to visit a regular general practitioner due to physical or psychological reasons. In the years 2013-2020 46% to 73% of the 8.380 MCH patients had no health care insurance., Conclusion: Patients consulting the MCH suffer from medical conditions typical for the homeless, namely skin diseases, wounds, injuries and behavioural disorders due to alcohol abuse, but also from "typical" symptoms in regular GP care as cough or lower back symptoms. Consultation reasons mostly are acute illnesses. Chronic diseases are equally present in regular GP and MCH patients, but pose a great challenge for the homeless among other things due to their irregular contact with the health care system. The lack of health insurance poses the greatest hurdle to the integration of the homeless into the regular health care system., (© 2023. The Author(s).)

Background: The huge increase of refugees to Germany caused a great challenge to the health system. We aimed to examine the level of patient-centredness in medical consultations with refugee patients, aided by video interpreters in primary care walk-in clinics (PCWC) in Hamburg., Methods: Videotaped consultations (N = 92) of 83 patients from 2017 to 2018 were analysed. Two raters used the Measure of Patient-Centered Communication (MPCC) and the International Classification of primary care (ICPC-2). MPCC scores with regard to patients' reason for seeking medical care and the procedures taken were explored using variance analyses adjusted for age, gender, and the duration of the consultation. The duration was further explored by Pearson correlations., Results: Patient-centredness of all consultations on average was 64% (95% CI 60-67) according to MPCC, with health-related issues affecting the results. The highest level of patient-centredness was achieved in psychological health issues with 79% (65-94), the lowest in respiratory ones with 55% (49-61). Longer consultations resulted in higher MPCC scores., Conclusions: The level of patient-centredness varied in the addressed health issues as well as in the duration of the consultation. Despite the variation, video interpreting in consultations supports a solid patient-centredness., Practice Implications: We recommend the use of remote video interpreting services for outpatient healthcare to support patient-centred communication and to fill the gap of underrepresentation of qualified interpreters on site, regarding a high diversity of spoken languages., (© 2023.
