Methoden Die Kommission „Telemedizinische Schlaganfallversorgung" der Deutschen Schlaganfall-Gesellschaft f{\"u}hrte eine Umfragestudie in allen Schlaganfall-Netzwerken durch. Ergebnisse In Deutschland sind 22 telemedizinische Schlaganfall-Netzwerke aktiv, welche insgesamt 43 Zentren (pro Netzwerk: Median 1,5, Interquartilsabstand [IQA] 1-3) sowie 225 Kooperationskliniken (pro Netzwerk: Median 9, IQA 4-17) umfassen und an einem unmittelbaren Zugang zur Schlaganfallversorgung f{\"u}r 48 Mio.

The aim of this study was to explore PCPs, namely General Practitioners' (GPs) and outpatient pediatricians' (PDs) knowledge of guideline recommendations on rational antimicrobial treatment, the determinants of confidence in treatment decisions and the perceived need for training in this topic in a large sample of PCPs from southern Germany. Out of 3753 reachable PCPs, 1311 completed the survey (overall response rate = 34.9\%). Knowledge of guideline recommendations and perceived confidence in making treatment decisions were high in both GPs and PDs. The two highest rated influencing factors on prescribing decisions were reported to be guideline recommendations and own clinical experiences, hence patients' demands and expectations were judged as not influencing treatment decisions. The majority of physicians declared to have attended at least one specific training course on antibiotic use, yet almost all the participating PCPs declared to need more training on this topic. More studies are needed to explore how consultation-related and context-specific factors could influence antibiotic prescriptions in general and pediatric primary care in Germany beyond knowledge. Moreover, efforts should be undertaken to explore the training needs of PCPs in Germany, as this would serve the development of evidence-based educational interventions targeted to the improvement of antibiotic prescribing decisions rather than being focused solely on knowledge of guidelines.}, language = {en} } @article{SaundersDavisKrankeetal.2018, author = {Saunders, Rhodri and Davis, Jason A. and Kranke, Peter and Weissbrod, Rachel and Whitaker, David K and Lightdale, Jenifer R}, title = {Clinical and economic burden of procedural sedation-related adverse events and their outcomes: analysis from five countries}, series = {Therapeutics and Clinical Risk Management}, volume = {14}, journal = {Therapeutics and Clinical Risk Management}, doi = {10.2147/TCRM.S154720}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-227508}, pages = {393-401}, year = {2018}, abstract = {Background: Studies have reported on the incidence of sedation-related adverse events (AEs), but little is known about their impact on health care costs and resource use. Methods: Health care providers and payers in five countries were recruited for an online survey by independent administrators to ensure that investigators and respondents were blinded to each other. Surveys were conducted in the local language and began with a "screener" to ensure that respondents had relevant expertise and experience. Responses were analyzed using Excel and R, with the Dixon's Q statistic used to identify and remove outliers. Global and country-specific average treatment patterns were calculated via bootstrapping; costs were mean values. The sum product of costs and intervention probability gave a cost per AE. Results: Responses were received from 101 providers and 26 payers, the majority having. 5 years of experience. At a minimum, the respondents performed a total of 3,430 procedural sedations per month. All AEs detailed occurred in clinical practice in the last year and were reported to cause procedural delays and cancellations in some patients. Standard procedural sedation costs ranged from (sic)74 (Germany) to \$2,300 (US). Respondents estimated that AEs would increase costs by between 16\% (Italy) and 179\% (US). Hypotension was reported as the most commonly observed AE with an associated global mean cost (interquartile range) of \$43 (\$27-\$68). Other frequent AEs, including mild hypotension, bradycardia, tachycardia, mild oxygen desaturation, hypertension, and brief apnea, were estimated to increase health care spending on procedural sedation by \$2.2 billion annually in the US. Conclusion: All sedation-related AEs can increase health care costs and result in substantial delays or cancellations of subsequent procedures. The prevention of even minor AEs during procedural sedation may be crucial to ensuring its value as a health care service.}, language = {en} } @article{HeinGamerGalletal.2021, author = {Hein, Grit and Gamer, Matthias and Gall, Dominik and Gr{\"u}ndahl, Marthe and Domschke, Katharina and Andreatta, Marta and Wieser, Matthias J. and Pauli, Paul}, title = {Social cognitive factors outweigh negative emotionality in predicting COVID-19 related safety behaviors}, series = {Preventive Medicine Reports}, volume = {24}, journal = {Preventive Medicine Reports}, doi = {10.1016/j.pmedr.2021.101559}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-265008}, year = {2021}, abstract = {Emotion-motivation models propose that behaviors, including health behaviors, should be predicted by the same variables that also predict negative affect since emotional reactions should induce a motivation to avoid threatening situations. In contrast, social cognitive models propose that safety behaviors are predicted by a different set of variables that mainly reflect cognitive and socio-structural aspects. Here, we directly tested these opposing hypotheses in young adults (N = 4134) in the context of COVID-19-related safety behaviors to prevent infections. In each participant, we collected measures of negative affect as well as cognitive and socio-structural variables during the lockdown in the first infection wave in Germany. We found a negative effect of the pandemic on emotional responses. However, this was not the main predictor for young adults' willingness to comply with COVID-19-related safety measures. Instead, individual differences in compliance were mainly predicted by cognitive and socio-structural variables. These results were confirmed in an independent data set. This study shows that individuals scoring high on negative affect during the pandemic are not necessarily more likely to comply with safety regulations. Instead, political measures should focus on cognitive interventions and the societal relevance of the health issue. These findings provide important insights into the basis of health-related concerns and feelings as well as behavioral adaptations.}, language = {en} } @article{VollmuthMuljukovAbuMugheisibetal.2021, author = {Vollmuth, Christoph and Muljukov, Olga and Abu-Mugheisib, Mazen and Angermeier, Anselm and Barlinn, Jessica and Busetto, Loraine and Grau, Armin J. and G{\"u}nther, Albrecht and Gumbinger, Christoph and Hubert, Nikolai and H{\"u}ttemann, Katrin and Klingner, Carsten and Naumann, Markus and Palm, Frederick and Remi, Jan and R{\"u}cker, Viktoria and Schessl, Joachim and Schlachetzki, Felix and Schuppner, Ramona and Schwab, Stefan and Schwartz, Andreas and Trommer, Adrian and Urbanek, Christian and Volbers, Bastian and Weber, Joachim and Wojciechowski, Claudia and Worthmann, Hans and Zickler, Philipp and Heuschmann, Peter U. and Haeusler, Karl Georg and Hubert, Gordian Jan}, title = {Impact of the coronavirus disease 2019 pandemic on stroke teleconsultations in Germany in the first half of 2020}, series = {European Journal of Neurology}, volume = {28}, journal = {European Journal of Neurology}, number = {10}, doi = {10.1111/ene.14787}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-259396}, pages = {3267-3278}, year = {2021}, abstract = {Background and purpose The effects of the coronavirus disease 2019 (COVID-19) pandemic on telemedical care have not been described on a national level. Thus, we investigated the medical stroke treatment situation before, during, and after the first lockdown in Germany. Methods In this nationwide, multicenter study, data from 14 telemedical networks including 31 network centers and 155 spoke hospitals covering large parts of Germany were analyzed regarding patients' characteristics, stroke type/severity, and acute stroke treatment. A survey focusing on potential shortcomings of in-hospital and (telemedical) stroke care during the pandemic was conducted. Results Between January 2018 and June 2020, 67,033 telemedical consultations and 38,895 telemedical stroke consultations were conducted. A significant decline of telemedical (p < 0.001) and telemedical stroke consultations (p < 0.001) during the lockdown in March/April 2020 and a reciprocal increase after relaxation of COVID-19 measures in May/June 2020 were observed. Compared to 2018-2019, neither stroke patients' age (p = 0.38), gender (p = 0.44), nor severity of ischemic stroke (p = 0.32) differed in March/April 2020. Whereas the proportion of ischemic stroke patients for whom endovascular treatment (14.3\% vs. 14.6\%; p = 0.85) was recommended remained stable, there was a nonsignificant trend toward a lower proportion of recommendation of intravenous thrombolysis during the lockdown (19.0\% vs. 22.1\%; p = 0.052). Despite the majority of participating network centers treating patients with COVID-19, there were no relevant shortcomings reported regarding in-hospital stroke treatment or telemedical stroke care. Conclusions Telemedical stroke care in Germany was able to provide full service despite the COVID-19 pandemic, but telemedical consultations declined abruptly during the lockdown period and normalized after relaxation of COVID-19 measures in Germany.}, language = {en} } @article{FehskeBerningerAlmetal.2021, author = {Fehske, Kai and Berninger, Markus T. and Alm, Lena and Hoffmann, Reinhard and Zellner, Johannes and K{\"o}sters, Clemens and Barzen, Stefan and Raschke, Michael J. and Izadpanah, Kaywan and Herbst, Elmar and Domnick, Christoph and Sch{\"u}ttrumpf, Jan Philipp and Krause, Matthias}, title = {Aktueller Versorgungsstandard von Patellafrakturen in Deutschland}, series = {Der Unfallchirurg}, volume = {124}, journal = {Der Unfallchirurg}, organization = {Komitee Frakturen der Deutschen Kniegesellschaft (DKG)}, issn = {0177-5537}, doi = {10.1007/s00113-020-00939-8}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-235047}, pages = {832-838}, year = {2021}, abstract = {Hintergrund Die Versorgung von Patellafrakturen ist technisch anspruchsvoll.
