Fulminant Heterotopic Ossification of the Lower Extremity After Gunshot Injury and Blunt Trauma: A Case Report.

Traumatic heterotopic ossification (HO) of the lower extremity is relatively rare but is of major importance in clinical practice. They are defined as posttraumatic abnormal formations of bone within soft tissue outside of the skeletal system. This article describes the clinical case of a 31-year-old male patient who suffered 2 traumatic events within 12 months-a gunshot wound in the lumbar spine/gluteal region followed by a severe traumatic brain injury with intracranial hemorrhage in a traffic accident as a pedestrian. Clinically, the patient was bedridden because of complete stiffening of the lumbar spine, both hip joints, and the left knee joint. After preoperative diagnosis, 3 surgical ablations of the HO were performed on both the hip joints and the left knee joint. In addition, physiotherapeutic exercise, postoperative nonsteroidal anti-inflammatory drug administration (25 mg of indomethazine for 6 weeks, 3 times a day), and perioperative radiation with 7 Gy for each operation were advised. After 4 years of follow-up, the patient showed significant improvement. In HO treatment, prophylactic local radiotherapy (pre- and postoperative radiation with a local single dose of 7 Gy) and postoperative administration of nonsteroidal anti-inflammatory drugs are often recommended. For therapeutic purposes, surgical resection is still indicated for pronounced cases.

Professional Social Media Use Among Orthopedic and Trauma Surgeons in Germany: Cross-Sectional Questionnaire-Based Study.

BACKGROUND: Social media (SM) has been recognized as a professional communication tool in the field of orthopedic and trauma surgery that can enhance communication with patients and peers, and increase the visibility of research and offered services. The specific purposes of professional SM use and the benefits and concerns among orthopedic and trauma surgeons, however, remain unexplored. OBJECTIVE: This study aims to demonstrate the specific uses of different SM platforms among orthopedic and trauma surgeons in Germany as well as the advantages and concerns. METHODS: A web-based questionnaire was developed on the use of SM in a professional context by considering the current literature and the authors' topics of interest. The final questionnaire consisted of 33 questions and was distributed among German orthopedic and trauma surgeons via the mail distributor of the Berufsverband für Orthopädie und Unfallchirurgie (Professional Association of Orthopaedic Surgeons in Germany). The study was conducted between June and July 2022. A subgroup analysis was performed for sex (male vs female), age (<60 years vs ≥60 years), and type of workplace (practice vs hospital). RESULTS: A total of 208 participants answered the questionnaire (male: n=166, 79.8%; younger than 60 years: n=146, 70.2%). In total, all of the participants stated that they use SM for professional purposes. In contrast, the stated specific uses of SM were low. Overall, the most used platforms were employment-oriented SM, messenger apps, and Facebook. Instagram emerged as a popular choice among female participants and participants working in hospital settings. The highest specific use of SM was for professional networking, followed by receiving and sharing health-related information. The lowest specific use was for education and the acquisition of patients. Conventional websites occupied a dominating position, exceeding the use of SM across all specific uses. The key benefit of SM was professional networking. Under 50% of the participants stated that SM could be used to enhance communication with their patients, keep up-to-date, or increase their professional visibility. In total, 65.5% (112/171) of participants stated that SM use was time-consuming, 43.9% (76/173) stated that they lacked application knowledge, and 45.1% (78/173) stated that they did not know what content to post. Additionally, 52.9% (91/172) mentioned medicolegal concerns. CONCLUSIONS: Overall, SM did not seem to be used actively in the professional context among orthopedic and trauma surgeons in Germany. The stated advantages were low, while the stated concerns were high. Adequate education and information material are needed to elucidate the possible professional applications of SM and to address legal concerns.

Social Media Use Among Orthopedic and Trauma Surgeons in Germany: Cross-Sectional Survey Study.

BACKGROUND: Social media (SM) has gained importance in the health care sector as a means of communication and a source of information for physicians and patients. However, the scope of professional SM use by orthopedic and trauma surgeons remains largely unknown. OBJECTIVE: This study presents an overview of professional SM use among orthopedic and trauma surgeons in Germany in terms of the platforms used, frequency of use, and SM content management. METHODS: We developed a web-based questionnaire with 33 variables and 2 separate sections based on a review of current literature. This study analyzed the first section of the questionnaire and included questions on demographics, type of SM used, frequency of use, and SM content management. Statistical analysis was performed using SPSS (version 26.0). Subgroup analysis was performed for sex, age groups (<60 years vs ≥60 years), and type of workplace (practice vs hospital). Differences between groups were assessed with a chi-square test for categorical data. RESULTS: A total of 208 participants answered the questionnaire (166/208, 79.8% male), of whom 70.2% (146/208) were younger than 60 years and 77.4% (161/208) worked in a practice. All participants stated that they use SM for private and professional purposes. On average, participants used 1.6 SM platforms for professional purposes. More than half had separate SM accounts for private and professional use. The most frequently used SM platforms were messenger apps (119/200, 59.5%), employment-oriented SM (60/200, 30%), and YouTube (54/200, 27%). All other SM, including Facebook and Instagram, were only used by a minority of the participants. Women and younger participants were more likely to use Instagram (P<.001 and P=.03, respectively). The participants working in a hospital were more likely to use employment-oriented SM (P=.02) and messenger apps (P=.009) than participants working in a practice. In a professional context, 20.2% (39/193) of the participants produced their own content on SM, 24.9% (48/193) used SM daily, 39.9% (77/193) used SM during work, and 13.8% (26/188) stated that they checked the number of followers they had. Younger participants were more likely to have participated in professional SM training and to have separate private and professional accounts (P=.04 and P=.02, respectively). Younger participants tended toward increased production of their own content (P=.06). CONCLUSIONS: SM is commonly used for professional purposes by orthopedic and trauma surgeons in Germany. However, it seems that professional SM use is not exploited to its full potential, and a structured implementation into daily professional work routines is still lacking. SM can have a profound impact on medical practices and communication, so orthopedic and trauma surgeons in Germany should consider increasing their SM presence by actively contributing to SM.

Development of Open Backend Structures for Health Care Professionals to Improve Participation in App Developments: Pilot Usability Study of a Medical App.

BACKGROUND: Efficient digitization in medicine still is in its infancy but undeniably has great potential for current and future challenges in health care. Thus far, the rollout of medical apps has not resulted in widespread use of smartphones in the German health care sector-the reasons for this have not been clarified so far. Nevertheless, the lack of user involvement in the development process and content creation might contribute to low acceptance of these products. OBJECTIVE: This study aims to outline an approach to involve medical expertise without any coding knowledge for developing medical app content and functions. METHODS: An end user-operable backend was built. Its usability was evaluated using a usability evaluation test protocol. The results of the usability tests were evaluated by the app development team, and the usability test was repeated for optimizing backend usability. In total, 40 criteria to measure the ease of app usage were defined a priori. The usability test comprised 20 tasks that had to be fulfilled. Usability tasks were analyzed for completion, dropout, and test duration. Due to the COVID-19 pandemic, digital videoconferencing platforms (Zoom and QuickTime Player) were used to complete usability questionnaires. Finally, several backend-based apps for several specialties (infectiology, plastic and reconstructive surgery, and orthopedics) were developed by health care professionals as prototypes. RESULTS: Initial usability testing was conducted with 5 participants (4 men and 1 woman; mean age 39.2, SD 5.97 years). All of them could complete the assigned backend tasks with only a few workflow interruptions and some minor errors. After usability optimization, the workflow completion time decreased from 5.03 minutes to 3.50 minutes, indicating a time saving. The basic backend structure was clear to all test users and the handling was intuitive to learn. Some minor errors in the backend occurred during the test rounds. The apps developed using the aforementioned approach are in clinical use as a proof of concept. CONCLUSIONS: Backends offering operability for medical professionals might have great potential for app development in the mobile health sector. Sophisticated and time-saving usability are pivotal for the acceptance of medical software, as illustrated by the backend-based apps presented herein, which are in clinical use as a proof of concept. Basic interventions are essential and sufficient for adequate usability optimization. Practicable, well-structured software usability evaluation is possible based on the usability evaluation test protocol.

Medical studies in times of a pandemic - concepts of digital teaching for Orthopaedics and Trauma at german universities.

BACKGROUND: Due to the Covid-19 pandemic, on-site classroom teaching became limited at most German medical universities. This caused a sudden demand for digital teaching concepts. How the transfer from classroom to digital teaching or digitally assisted teaching was conducted was decided by each university and/or department individually. As a surgical discipline, Orthopaedics and Trauma have a particular focus on hands-on teaching as well as direct contact to patients. Therefore, specific challenges in designing digital teaching concepts were expected to arise. Aim of this study was to evaluate medical teaching at German universities one year into the pandemic as well as to identify potentials and pitfalls in order to develop possible optimization approaches. METHODS: A questionnaire with 17 items was designed and sent to the professors in charge of organising the teaching in Orthopaedics and Trauma at each medical university. A differentiation between Orthopaedics and Trauma was not made to allow a general overview. We collected the answers and conducted a qualitative analysis. RESULTS: We received 24 replies. Each university reported a substantial reduction of their classroom teaching and efforts to transfer their teaching to digital formats. Three sites were able to switch to digital teaching concepts completely, whereas others tried to enable classroom and bedside teaching at least for students of higher edcuational levels. The online platforms used varied depending on the university as well as the format it was supposed to support. CONCLUSION: One year into the pandemic significant differences concerning the proportions of classroom and digital teaching for Orthopaedics and Trauma can be observed. Simultaneously huge differences in concepts used to create digital teaching are present. Since a complete suspense of classroom teaching was never mandatory, several universities developed hygiene concepts to enable hands-on and bedside teaching. Despite these differences, some similarities were observed: the lack of time and personnel to generate adequate teaching material was reported as the leading challenge by all participants of this study.

Orthopaedic and trauma surgeons' prioritisation of app quality principles based on their demographic background.

BACKGROUND: Although apps are becoming increasingly relevant in healthcare, there is limited knowledge about how healthcare professionals perceive "quality" in this context and how quality principles that can aid them in assessing health-related apps may be prioritised. The objective was to investigate physicians' views of predefined (general) quality principles for health apps and to determine whether a ranking algorithm applied to the acquired data can provide stable results against various demographic influences and may thus be appropriate for prioritisation. METHODS: Participants of an online survey of members of two German professional orthopaedics associations conducted between 02/12/2019 and 02/01/2020 were asked about their perception of a set of quality principles for health apps (i.e., "practicality," "risk adequacy," "ethical soundness," "legal conformity," "content validity," "technical adequacy," "usability," "resource efficiency," and "transparency"). Structured as a Kano survey, for each principle, there were questions about its perceived relevance and opinions regarding the presence or absence of corresponding characteristics. The available data were evaluated descriptively, and a newly developed method for prioritisation of the principles was applied overall and to different demographic strata (for validation). RESULTS: Three hundred eighty-two datasets from 9503 participants were evaluated. Legal conformity, content validity, and risk adequacy filled ranks one to three, followed by practicability, ethical soundness, and usability (ranks 4 to 6). Technical adequacy, transparency, and resource efficiency ranked last (ranks 7 to 9). The ranking based on the proposed method was relatively stable, irrespective of demographic factors. The principles were seen as essential, with one exception ("resource efficiency"). Only those with little to no interest in digitisation (22/382, 5.8%) rated the nine principles indifferently. CONCLUSIONS: The specified quality principles and their prioritisation can lay a foundation for future assessments of apps in the medical field. Professional societies build upon this to highlight opportunities for digital transformations in medicine and encourage their members to participate.

Joint and Functional Examinations in the Orthopaedic and Traumatological Video Consultation - What is Currently Possible? / Orthopädisch-unfallchirurgische Funktionsuntersuchung in der Online-Videosprechstunde ­ was ist heute möglich?

BACKGROUND: In the context of the COVID-19 pandemic, video consultations have gained importance in orthopaedic and traumatological departments. In current literature, different adaptations of classic joint and functional examinations have been described for the virtual examination. METHODOLOGY: A systematic review of current literature on adaptations for the virtual joint and functional examination in orthopaedics and trauma surgery was performed over PubMed (January 2010 to April 2021). The identified examination methods were then summarised systematically according to body region and pathology. Each examination was then described in detail and depicted in an exemplary picture. RESULTS: In total 17 articles were identified and included in the analysis. Most of the examinations employed classical examination methods which were adapted so that they could be performed by the patient independently. Everyday items were described as supporting tools. In five publications, orthopaedic examinations performed in video consultations were compared to the classical examination. Results of functional examinations showed less agreement with results of classical orthopaedic examinations when compared to inspection and ROM-testing. CONCLUSION: Current literature offers a substantial repertoire of examination options that can be used in the orthopaedic and traumatological video consultation. The reported examinations are mostly oriented to classical orthopaedic examinations. In future digital examinations have to be validated and possibly further adapted in future.

Is student mentoring career-defining in surgical disciplines? A comparative survey among medical schools and medical students for mentoring programs.

Objective: Facing a shortage of young surgeons, this study aimed to examine the availability of mentoring programs and if this can counteract this lack. Summary background data: Medical mentoring programs have proven to be decisive to influence students' later career decisions. Since their structure may depend on the medical school and the effort of single disciplines, the offers are often very heterogeneous. Methods: Anonymous online-questionnaires were developed and distributed among medical students in Germany and the dean for teaching of the medical schools from July 2019 to January 2020 in Germany. Data of the availability of mentoring programs, their structure and the impact of surgery were collected. Results: Forty three medical schools participated, with 65% offering mentoring programs. 18 of medical schools had no additional funding available for this. Surgical subjects participated in these programs in only 30%. Additionally, 1,516 medical students participated in the second survey. A total of 70% had already participated in a mentoring program with a significantly higher proportion of men. Of these, 94% stated that this was helpful and had an impact on their career planning, without any gender differences. 95% would participate in structured surgical mentoring programs and 95% agreed that this could have an impact on their career planning. Conclusion: Mentoring programs may be able to influence career planning, nevertheless participation by surgical specialties has been low. Becoming more active in providing mentoring programs with a special focus on women and offering more surgical content can be a way to counteract the lack of surgical trainees.

Decision support by machine learning systems for acute management of severely injured patients: A systematic review.

Introduction: Treating severely injured patients requires numerous critical decisions within short intervals in a highly complex situation. The coordination of a trauma team in this setting has been shown to be associated with multiple procedural errors, even of experienced care teams. Machine learning (ML) is an approach that estimates outcomes based on past experiences and data patterns using a computer-generated algorithm. This systematic review aimed to summarize the existing literature on the value of ML for the initial management of severely injured patients. Methods: We conducted a systematic review of the literature with the goal of finding all articles describing the use of ML systems in the context of acute management of severely injured patients. MESH search of Pubmed/Medline and Web of Science was conducted. Studies including fewer than 10 patients were excluded. Studies were divided into the following main prediction groups: (1) injury pattern, (2) hemorrhage/need for transfusion, (3) emergency intervention, (4) ICU/length of hospital stay, and (5) mortality. Results: Thirty-six articles met the inclusion criteria; among these were two prospective and thirty-four retrospective case series. Publication dates ranged from 2000 to 2020 and included 32 different first authors. A total of 18,586,929 patients were included in the prediction models. Mortality was the most represented main prediction group (n = 19). ML models used were artificial neural network ( n = 15), singular vector machine (n = 3), Bayesian network (n = 7), random forest (n = 6), natural language processing (n = 2), stacked ensemble classifier [SuperLearner (SL), n = 3], k-nearest neighbor (n = 1), belief system (n = 1), and sequential minimal optimization (n = 2) models. Thirty articles assessed results as positive, five showed moderate results, and one article described negative results to their implementation of the respective prediction model. Conclusions: While the majority of articles show a generally positive result with high accuracy and precision, there are several requirements that need to be met to make the implementation of such models in daily clinical work possible. Furthermore, experience in dealing with on-site implementation and more clinical trials are necessary before the implementation of ML techniques in clinical care can become a reality.

How far has the digitization of medical teaching progressed in times of COVID-19? A multinational survey among medical students and lecturers in German-speaking central Europe.

BACKGROUND: To ensure successful medical education despite the COVID-19 pandemic, the demand for online instruction has substantially increased. Fast and efficient teaching in a digital format poses a great challenge for medical students and lecturers as well as the universities. OBJECTIVE: The aim of this study is to capture the readiness of medical students and faculty members to participate in rapidly- evolving online education. METHODS: This cross-sectional study is based on two questionnaires distributed among medical students and associate deans for education in Germany, Austria and Switzerland. Questions included decision- making questions, categorical questions, and open-ended questions, all addressing the frequency and format of the digital education offered, the perceived quality of digital education, and medical student satisfaction with digital education. Questions about missing content and areas for improvement from the perspectives of medical students were included. The associate deans were asked for their opinions about the impact of the pandemic on teaching, the organizational setup and implementation of digital education by universities, and plans for future initiatives. RESULTS: Three thousand and thirty medical students (m = 752 and f = 2245) from 53 universities participated in the study. The study showed that 92% of students were affected by the pandemic, and 19% of the students viewed the changes as entirely negative. 97% of the medical students were able to participate in digital courses, but only 4% were able to learn exclusively online. For 77% of the medical students, digital offerings accounted for over 80% of the education offered. In terms of content, medical students complained about a lack of practical teaching, such as contact with patients, lecturers, fellow medical students, and a poor perceived quality of teaching due to dubbing, frequent changeover of seminars, problem-oriented learning groups and in-person teaching, a lack of interaction possibilities and a lack of technical equipment, such as lecturers' knowledge and server capacities, at the universities. Overall, almost half of the medical students (42%) rated the implementation of digital teaching at their universities as good or very good. Forty-one of the 53 associate deans responded to the questionnaire, and 35 felt medical education was influenced by the pandemic. The associate deans (80%; 33/41) felt that the digitalization of medical education was negatively influenced by the pandemic. Only 44% (18/41) felt that their universities were well or very well positioned for digital teaching. All the associate deans believe that digital teaching in medicine will continue after the pandemic. CONCLUSIONS: In the German-speaking world, the rapid conversion of medical teaching to a digital format has been well implemented in many cases. The perceived quality of the implementation of digital education still lacks practical relevance and the use of new digital media, such as learning games, VR, and online question time. The digital format of medical education will likely continue beyond the COVID-19 pandemic.

Digital implications for human resource management in surgical departments.

BACKGROUND: Changes in demographics and dynamics of our society are affecting the healthcare system, leading to an intensified "war for talents," especially for surgical departments. Also with regard to the current COVID-19 pandemic, the present work analyzes the potential of digitalization for human resource management of surgical departments in hospitals. METHODS: PubMed and Google Scholar were searched to identify articles referring to the specific subject of human resource management and its digital support in hospitals and surgical departments in particular. RESULTS: The main topics include the digital affinity of young physicians and surgeons in terms of staff recruiting, digital support for everyday working life in surgical departments, and the potential of digital approaches for surgical training. These topics are put into the context of company strategies, and their future potential is identified accordingly. CONCLUSION: Digital programs, digital structures, and digital tools can today be used by human resources departments to advertise the hospital and to make the recruitment of future candidates increasingly attractive. In addition, by making digital tools available, the employees' satisfaction can be raised with the potential of a strong employer branding. In times of the COVID-19 pandemic, digital personnel strategies and training formats have to be regarded a contemporary offering.

Routine laboratory parameters predict intensive care unit admission and hospitalization in patients suffering stab injuries.

Background: Knife crime has increased considerably in recent years in Northern Europe. Affected patients often require immediate surgical care due to traumatic organ injury. Yet, little is known about clinically relevant routine laboratory parameters in stab injury patients and how these are associated with intensive care unit (ICU) admission, hospitalization and number of surgeries. Methods: We retrospectively analyzed 258 stab injury cases between July 2015 and December 2021 at an urban Level I Trauma Center. Annual and seasonal incidences, injury site, injury mechanism, Injury Severity Score (ISS), and surgical management were evaluated. First, correlations between routine laboratory parameters for hematology, coagulation, and serum biochemistry (peak, and Δ (change from admission to peak within 3 days following admission)) and length of hospital stay, ICU stay, and number of surgeries were assessed using Spearman's rank correlation coefficients. Second, multivariable Least Absolute Shrinkage and Selection Operator (LASSO) regression analyses were conducted to identify parameters predictive of clinical outcomes. Third, longitudinal developments of routine laboratory parameters were assessed during hospital admission. Results: In 2021, significantly more stab injuries were recorded compared with previous years and occurred less during winter compared with other seasons. Mean ISS was 8.3 ± 7.3, and ISS was positively correlated with length of hospital and ICU stay (r = 0.5-0.8, p < 0.001). Aspartate transaminase (AST) (Δ) (r = 0.690), peak C-reactive protein (CrP) (r = 0.573), and erythrocyte count (Δ) (r = 0.526) showed the strongest positive correlations for length of ICU stay for penetrating, thoracoabdominal, and organ injuries, respectively. No correlations were observed between routine laboratory parameters and number of surgeries. For patients with penetrating injuries, LASSO-selected predictors of ICU admission included ISS, pH and lactate at admission, and Δ values for activated partial thromboplastin time (aPTT), K+, and erythrocyte count. CrP levels on day 3 were significantly higher in patients with penetrating (p = 0.005), thoracoabdominal (p = 0.041), and organ injuries (p < 0.001) compared with those without. Conclusion: Our data demonstrate an increase in stab injury cases in 2021 and an important link between changes in routine laboratory parameters and ICU admission and hospitalization. Monitoring ISS and changes in AST, CrP, erythrocyte count, pH, lactate, aPTT, and K+ may be useful to identify patients at risk and adjust surgical and ICU algorithms early on.

Acceptance of Supportive Illustrations for Preparation of Patients for an Orthopedic Telemedical Consultation.

Introduction: Telemedical video consultations are a powerful support for patient-doctor interactions. For optimal digital settings, explanatory illustrations may be helpful for patients. This study analyzed patients' the attitude of patients to illustrations preparing for an orthopedic telemedical consultation (OTC). Methods: A leaflet with eight illustrations was designed and their acceptance and estimated necessity was evaluated among patients who had experienced an OTC (EXP-group) and others who had not (NOV-group) with a 12-item-questionnaire. Results: Sixty patients participated (n = 30 each group). All illustrations were evaluated positively. The EXP-group gave significantly higher ratings than the NOV-group for improved understanding by the given keywords of the illustrations (p = 0.046), preference for being informed by illustrations than by merely by a pure text (p = 0.023), better feeling of preparation for an OTC by the illustrations (p = 0.005), and the impression of a simplified process of the OTC by the illustrations (p = 0.012). Discussion: While the illustrations were well-accepted by the participants, significant differences were revealed between the valuation of single aspects by patients, depending on a previous experience with an OTC. Therefore, a leaflet with explanatory illustrations may be helpful in preparing patients for an OTC to support the digital patient-doctor contact.

An Augmented Reality Device for Remote Supervision of Ultrasound Examinations in International Exercise Science Projects: Usability Study.

BACKGROUND: Support for long-distance research and clinical collaborations is in high demand and has increased owing to COVID-19-related restrictions on travel and social contact. New digital approaches are required for remote scientific exchange. OBJECTIVE: This study aims to analyze the options of using an augmented reality device for remote supervision of exercise science examinations. METHODS: A mobile ultrasound examination of the diameter and intima-media thickness of the femoral and carotid arteries was remotely supervised using a head-mounted augmented reality device. All participants were provided with a link to a YouTube video of the technique in advance. In part 1, 8 international experts from the fields of engineering and sports science were remotely connected to the study setting. Internet connection speed was noted, and a structured interview was conducted. In part 2, 2 remote supervisors evaluated 8 physicians performing an examination on a healthy human subject. The results were recorded, and an evaluation was conducted using a 25-item questionnaire. RESULTS: In part 1, the remote experts were connected over a mean distance of 1587 km to the examination site. Overall transmission quality was good (mean upload speed: 28.7 Mbps, mean download speed: 97.3 Mbps, mean ping: 21.6 milliseconds). In the interview, participants indicated that the main potential benefits would be to the fields of education, movement analysis, and supervision. Challenges regarding internet connection stability and previous training with the devices used were reported. In part 2, physicians' examinations showed good interrater correlation (interclass correlation coefficient: 0.84). Participants valued the experienced setting as highly positive. CONCLUSIONS: The study showed the good feasibility of the chosen design and a highly positive attitude of all participants toward this digital approach. Head-mounted augmented reality devices are generally recommended for collaborative research projects with physical examination-based research questions.

[Generation "Social Media": use of modern media to gain information regarding sports injuries]. / Generation "Social Media" ­ Nutzung moderner Medien zum Informationsgewinn bezüglich Sportverletzungen.

BACKGROUND: Digital media have found their way into almost all areas of daily life. The aim of this study was to analyse the extent to which injured athletes use online media to gather information on sports injuries or on how to prevent them. MATERIAL AND METHODS: Between 07-2017 and 12-2019, both recreational and competitive climbing athletes were surveyed on their use of various media with regard to sports medicine and prevention. RESULTS: 488 athletes were included in the study (70.9 % male, 29.1 % female, 33.2 ±â€Š10.3 (13-71) years of age). 69.9 % of the athletes use web-based medical content, with the video platform YouTube being most frequently used for specific searches (24.4 %). Younger athletes (< 30y) use video platforms significantly more often than older athletes (p = 0.011). Sports-specific literature is most frequently used by the age group 30-50 years (37.4 %). The age group > 50 uses this medium significantly less frequently (18.8 %; p = 0.013). Competitive athletes use web-based medical content significantly more often than recreational athletes (p = 0.005). The general interest in injury prevention is high, with competitive athletes using relevant content more often. Almost 9 % of all patients interviewed visited a sports-orthopaedic facility because of their online research work. SUMMARY: Internet-based medical information is used by 69.9 % of athletes, with the video platform YouTube being most frequently used. Video platforms and sports-specific literature are used significantly more often by younger athletes than by older athletes. Web-based medical content is accessed significantly more often by professional athletes than by recreational athletes. The general interest in injury prophylaxis is high, with competitive athletes using or browsing medical content more often.

Instructing Ultrasound-guided Examination Techniques Using a Social Media Smartphone App.

Social media applications on smartphones allow for new avenues of instruction in sports medicine and exercise sciences. This study tested the feasibility of instructing health care personnel through videos of ultrasound vascular measurements distributed by a social media messenger application. After two training sessions with an ultrasound device, voluntary physicians (n=10) and nurses (n=10) received a video for the performance of an ultrasound-guided determination of intima-media-thickness and diameter of the femoral arteries via a social media messenger application. All participants examined the same healthy human subject. There was no significant difference between the groups regarding overall time of performance, measurements of the femoral arteries, or a specifically designed "assessment of mobile imparted arterial ultrasound determination" score. The physicians group achieved significantly higher scores in the established "objective structured assessment of ultrasound skills" score (p=0.019). Approval of the setting was high in both groups. Transmission of videos via social media applications can be used for instructions on the performance of ultrasound-guided vascular examinations in sports medicine, even if investigators' performances differ depending on their grade of ultrasound experience. In the future, the chosen approach should be tested in practical scientific examination settings.

The Digital Healthcare Act - a Turning Point in the German Digitisation Strategy? / Das Digitale-Versorgung-Gesetz ­ eine Zäsur der deutschen Digitalisierungsstrategie?

The recently ratified Digital Healthcare Act - DVG - has paved the way, among other issues, for the prescription of health apps. The German DVG creates an entitlement to health apps for the very first time. However, this entitlement is initially limited to low-risk medical devices that have been included in the publicly accessible Register for Digital Health Applications by the German Federal Institute for Drugs and Medical Devices. Listing in the register is granted, if the manufacturer has submitted a health app and verified that it meets basic requirements for medical devices and data security as well as positive health care effects. It is questionable, whether the DVG will lead to sustainable improvements in future patient care. In order to pursue this question and align the DGOUC's digitization strategy closely with its basis, an online survey was conducted among the respective members on the DVG's content and its associated opportunities and risks. A total of 461 German-speaking, predominantly male, experienced and elderly physicians in leading positions took part in the survey. In this study, it was shown that the majority of the participating German orthopaedic and trauma surgeons is not familiar with the DVG's contents. Despite a fundamentally positive attitude towards digitization, scepticism about the use of "apps on prescription" and potential risks still prevails at present. The closing of ranks between medicine, IT and the legislature via interdisciplinary expert groups and the involvement of medical societies might be obligatory.

Smartphone and App Usage in Orthopedics and Trauma Surgery: Survey Study of Physicians Regarding Acceptance, Risks, and Future Prospects in Germany.

BACKGROUND: In the course of digitization, smartphones are affecting an increasing number of areas of users' lives, giving them almost ubiquitous access to the internet and other web applications. Mobile health (mHealth) has become an integral part of some areas of patient care. In contrast to other disciplines, routine integration of mobile devices in orthopedics and trauma surgery in Germany is still in its infancy. OBJECTIVE: This study aimed to investigate physicians' current state of opinion regarding acceptance, future prospects, and risks of medical apps in the field of orthopedics and trauma surgery in Germany. METHODS: A web-based survey among orthopedics and trauma surgeons in German university hospitals on the use of medical apps in everyday clinical practice was conducted between September 2018 and February 2019. The survey consisted of 13 open- and closed-ended or multiple-choice questions. A logistic regression analysis was performed to ascertain the effects of interindividual characteristics on the likelihood of participants' app and smartphone usage behavior. RESULTS: A total of 206 physicians participated in the survey. All of the participants (206/206, 100%) owned a smartphone, and 79.1% (159/201) used the device, while 64.7% (130/201) used apps regularly in everyday clinical practice. Medical apps were perceived as beneficial, given their substantial future promise, by 90.1% (181/201) of the participants. However, 62.5% (120/192) of the participants were not satisfied with the current supply of medical apps in app stores. Desired specifications for future apps were "intuitive usability" (167/201, 83.1%), "no advertising" (145/201, 72.1%), and "free apps" (92/201, 45.8%). The attributes "transparent app development and app sponsoring" (75/201, 37.3%) and the existence of an "easy-to-understand privacy statement" (50/201, 24.9%) were of minor relevance. The majority of the participants (162/194, 83.5%) considered that future apps in the field of "medical research" would provide the greatest benefit. The greatest predicted risks were "data misuse" (147/189, 77.8%), "usage of untrustworthy apps" (135/189, 71.4%), and "alienation from patients" (51/189, 27.0%). Increasing age was significantly associated with a reduction in the likelihood of regular smartphone (odds ratio [OR] 0.91, 95% CI 0.86-0.97; P=.002) and app (OR 0.90, 95% CI 0.85-0.96; P=.001) usage, while the medical profession grade had no significant impact on the usage behavior. CONCLUSIONS: The study demonstrates that young German doctors in orthopedics and trauma surgery already use smartphones and apps in everyday clinical practice. Medical apps are considered to play an important role in the future. However, a significant discrepancy exists between the supply and demand of mHealth applications, which creates a legal and ethical vacuum with regard to data protection.

Undergraduate Medical Competencies in Digital Health and Curricular Module Development: Mixed Methods Study.

BACKGROUND: Owing to an increase in digital technologies in health care, recently leveraged by the COVID-19 pandemic, physicians are required to use these technologies appropriately and to be familiar with their implications on patient care, the health system, and society. Therefore, medical students should be confronted with digital health during their medical education. However, corresponding teaching formats and concepts are still largely lacking in the medical curricula. OBJECTIVE: This study aims to introduce digital health as a curricular module at a German medical school and to identify undergraduate medical competencies in digital health and their suitable teaching methods. METHODS: We developed a 3-week curricular module on digital health for third-year medical students at a large German medical school, taking place for the first time in January 2020. Semistructured interviews with 5 digital health experts were recorded, transcribed, and analyzed using an abductive approach. We obtained feedback from the participating students and lecturers of the module through a 17-item survey questionnaire. RESULTS: The module received overall positive feedback from both students and lecturers who expressed the need for further digital health education and stated that the field is very important for clinical care and is underrepresented in the current medical curriculum. We extracted a detailed overview of digital health competencies, skills, and knowledge to teach the students from the expert interviews. They also contained suggestions for teaching methods and statements supporting the urgency of the implementation of digital health education in the mandatory curriculum. CONCLUSIONS: An elective class seems to be a suitable format for the timely introduction of digital health education. However, a longitudinal implementation in the mandatory curriculum should be the goal. Beyond training future physicians in digital skills and teaching them digital health's ethical, legal, and social implications, the experience-based development of a critical digital health mindset with openness to innovation and the ability to assess ever-changing health technologies through a broad transdisciplinary approach to translate research into clinical routine seem more important. Therefore, the teaching of digital health should be as practice-based as possible and involve the educational cooperation of different institutions and academic disciplines.
