Basic suture technique: Instructional videos explaining suturing for medical students in a qualitative study.
Ontology highlight
ABSTRACT: Background
Understanding basic surgical skills is important for medical students prior to entering residency regardless of future specialty. In these videos we provide instruction for suturing as it relates to skin closure.Material and methods
Instructional videos were created by the senior faculty (R.A. and M.K.) to teach medical students at the University of Louisville suturing techniques.Results
Entering and exiting the needle at an angle of 90° or greater allows for tissue eversion. Inadequate eversion of tissue or inadequate angling of the needle will lead to tissue inversion. When suturing uneven edges, a deep bite on the low side and a shallow bite on the high side will allow for appropriate tissue leveling. For buried sutures, skin eversion with substantial dermal bites and proper knot location is essential.Conclusion
Understanding the basics of skin apposition will provide students with knowledge about primary wound healing and prepare them for residency.

Project description:BackgroundThe YouTube channel "TiHoVideos" was created by the University of Veterinary Medicine Hannover, Foundation (TiHo) to enable easy, public access to the university's instructional videos as an additional support for learning clinical skills. Video production is expensive and time-consuming. To be able to optimize video production and aligning content to student needs we wanted to know if and how our students use these videos.ResultsResults show that the participating students primarily prepared for learning stations in the Clinical Skills Lab (CSL) by watching TiHoVideos at home on tablets or laptops and then concentrated at the CSL on learning the practical skills hands on. The videos available on TiHoVideos are rated as being a "very helpful" educational tool when preparing for CSL learning stations.ConclusionsInstructional videos represent an unquestionably suitable medium to aid veterinary students learn practical skills and a contribution to animal welfare by reducing the use of live animals in undergraduate veterinary education. The university's production of educational video material proves to be worth the effort because the videos are being used, appreciated and well-rated by TiHo students for their learning experience.

Project description:Introduction: In 2012 safety strategies were defined in five intervention areas to improve patient safety in Austria. Regarding policy development, patient safety should be mandatory part of education of all healthcare sectors, and measures to improve hygiene standards are to be included in organizational development. The aim of this project was to achieve sustained improvement in routine procedures and anchor patient safety in the undergraduate medical curriculum by making online instructional videos on clinical skills and hygiene procedures permanently available as preparation for the first clinical clerkship. Method: Short films explaining how to insert urinary catheters in women and men were produced and provided online. These videos were shown to medical students shortly before the practical Objective Structured Clinical Examination (OSCE). After viewing the videos, all of the students were surveyed using an online questionnaire with 15 questions regarding quality and acceptance. The effect of the videos on learning success was determined by the assessment outcome through red cards in the practical exam. A red card for behavior endangering the doctor or others meant zero points and discontinuation of the assessment at that particular OSCE station. Results: A total of 647 students viewed one of the two videos on urinary catheters, 623 responded to the online Moodle questionnaire completly. 551 (85.2%) reported being better able to recall individual steps and procedures, 626 students (96.7%) positively rated the fact that instructional videos were available on the Medical University of Vienna's website. More than half of the respondents (56.6%) were better able to remember critical hygiene practices. The comparison of the assessment outcomes on the OSCE for 2016 and 2013, a year in which the instructional videos were not yet available, shows no significant (chi2=3.79; p>0.05) but a trend towards improvement. The chance of getting a red card in 2013 was 3.36 times higher than in 2016. Conclusion: Even if our study was unable to show significant improvements in the OSCE as a result of viewing the videos, it appears that clearly imparting medical skills and hygiene standards-including in visual form-is still important prior to the first clerkship to ensure the highest level of patient safety possible. The combination of teaching and learning formats, such as videos on online platforms with textbooks or lecture notes, is well suited to increase effectiveness and efficiency in learning. There is a need for further studies to investigate and analyze the effects of instructional videos in more detail.

Project description:Background: The physical examination (PE) of patients is a core competence in almost all medical disciplines. The teaching materials "Heidelberger Standard Examination", consisting of a handbook and accompanying videos, were developed with the objective of providing medical students with an innovative faculty-wide teaching and examination standard to sustainably advance students' PE competences during medical training. Methods: In a "mixed-method approach" comprising both quantitative and qualitative measures, our study examined Heidelberg University Hospital final year (FY) medical students' use and evaluation of the individual teaching material components. Therefore, 92 FY students completed quantitative evaluation measures and ten FY students took part in individual 30-minute semi-structured interviews. Results: Of the sample of n=77 students, who had completed the clinical part of their studies at Heidelberg University Hospital, 97.4% (n=75) had used the handbook and 35.0% (n=27) the accompanying videos. The teaching materials were evaluated via the common German six-point school grading system with an average mark of 1.35±0.5 for the handbook and a mark of 2.15±1.0 for the accompanying videos. Further, our results show that FY students especially valued the "Heidelberg Standard Examination" handbook as a guide and general reference work and felt the materials improved their self-perceived PE competence. Although FY students saw the accompanying video material as helpful, it was less frequently used, indicating further development potential. Overall, results reveal that FY students perceive the "Heidelberg Standard Examination" teaching program to contribute to the improvement of the quality of their PE training.

Project description:The use of online teaching mode has grown rapidly in recent years, particularly under the COVID-19 pandemic. To promote the learning motivation of students and teaching effectiveness, development of attractive online teaching material such as videos is important. In the present study, we developed 15 theory-related videos and 9 case-based videos in the context of a leadership course focusing on psychological well-being and psychosocial competence. Using a qualitative research methodology via focus groups (N = 48 students) to evaluate these videos, six themes emerged from the data, including video arrangement, design of videos, content of videos, benefits to students' pre-lesson self-learning, benefits to students' learning of course content, and contribution to students' class participation. The findings suggest that the videos can elicit positive perceptions of the students in a flipped classroom arrangement. Students also benefit from the videos in terms of their understanding of course content and their participation in class discussion. Besides, the study suggests that the videos promote the learning efficiency of the students. The present qualitative findings concurred with the previous quantitative findings, suggesting the value of using virtual teaching and learning to promote psychosocial competence in university students.

Project description:BackgroundToday, flipped classroom (FC) has been widely used in medical education. However, the effectiveness of FC remains controversial. The variation may cause by different subjects or different course design. Moreover, those studies did not explain how the association among different domains of learning objective was in FCs. The purpose of this study was to explore the help of learning domains from a FC of suturing skill in year-5 medical students.DesignThis study determined sample size according to statistical power. A minimum number of 77 participants for regression analysis are needed. Therefore, this study enrolled 78 medical students in a 2-hour suturing course, which consisted of pre-class video and in-class instruction. Both simple and mattress suturing were taught. The students received an anonymous survey with questionnaire of Help from Instruction Questionnaire for Clinical Skills (HIQ-CS) after the course. The HIQ-CS was developed by medical education team according to Bloom's taxonomy, and its reliability was favorable (Cronbach's ^l = 0.839). Factor loadings among all items in the HIQ-CS was also favorable (0.790 to 0.849). This study determined consensus of students' perspective by median (Me) and interquartile range (IQR), and tested mediation among different learning domains by regression.ResultsThe results showed medical students agreed FC can help them in learning suturing (Me = 4, IQR = 1). The cognitive help (β = .526, p < .001) was completely mediated by psychomotor help (β = .399, p < .001) and affective help (β = .413, p < .001) to overall helps in FC. The affective help (β = .617, p < .001) was partially mediated by psychomotor help to overall helps in FC.ConclusionsFC may help students in learning suturing skill in different domains. Our model explains the cognitive help from FC provides an important foundation for the helps of other domains. Although the model should be examined by different curricula and measurements in future, the model of help from instruction in our study provided an innovated concept and framework in medical education.

Project description:The discussion about how to present instructors in instructional videos has become a hot topic in recent years. This systematic review explores how the instructors' presence affects affective, cognitive, and social aspects of learning in different conditions and with different video types. The review analyses 41 empirical studies indexed in Web of Science, ERIC, Scopus, and Education Source research databases from 2014 to 2022. The results indicated that (i) many instructor-present videos were in picture-in-picture format and included direct gaze as a social cue, (ii) learners had positive feelings for instructor-present videos, (iii) the on-screen instructor could not be beneficial for gathering positive learning outcomes, but social and attentional cues provided by the on-screen instructor could foster learning, and (iv) findings regarding the social aspect of learning were inconclusive. This study also emphasizes the need for further studies to clearly explore the role of the instructor in different learning conditions.Supplementary informationThe online version contains supplementary material available at 10.1007/s10639-022-11532-4.

Project description:In self-directed learning environments, students must monitor and assess their learning progress themselves. Formative assessments play a central role as instructional tools to train students in these self-assessment skills. Key to the effectiveness of a formative assessment as a training instrument is the degree of student involvement in the design and implementation of the formative assessment used to train them. Five characteristics are essential to secure a sufficient level of student involvement: (1) congruence (i.e., the tasks of a formative assessment must reflect the instructional content), (2) authenticity (i.e., the tasks of a formative assessment should be related to students' background and study context), (3) consultation (i.e., students should have a say in how their answers are evaluated based on which criteria), (4) transparency (i.e., no "mystery items"-the wording of the items must clearly addresses the targeted content), and (5) accommodation (i.e., all students should have the same chance to complete the items of a formative assessment). These five characteristics of student involvement were used to evaluate the quality of formative assessments that are employed to train undergraduates in a medical school in self-assessment skills. Different from extant approaches that typically rely on instructors' judgments to infer the degree of student involvement, this study uses a paradigm in higher educational research asking students directly about their perceptions of an instructional tool. Thus, here, students had to rate their level of involvement in the design and implementation of the formative assessments used to train them. A total of 140 medical students participated in the study. Multivariate statistical methods were used to analyze the data. The majority of medical students appreciate the use of formative assessments to teach them self-directed learning skills; but the results also show that there is still room for increasing student involvement-especially, for minority students.

Project description:Creation of guidelines and education on digital professionalism have been sluggish despite the ever-increasing use of social media by digitally native medical students, who are at risk of blurring the line between their professional and personal lives online. A qualitative thematic analysis was applied on 79 videos extracted from 70,154 YouTube videos uploaded by Korean medical students between March and April 2020. We found 20% contained at least one concerning behavior themed under 'failure to engage,' 'disrespectful behaviors,' or 'poor self-awareness.' Professional lapses identified were classified into seriousness levels. Mostly were "controversial' or 'concerning' but some 'highly concerning' contents were also found. This is the first study on digital professionalism behavior on medical students' YouTube videos. The potential negative impact on the medical profession of the easily accessible public online videos cannot be ignored and thus we suggest the need for them to be taken more seriously.

Project description:BackgroundLarger gastrojejunal (GJ) anastomosis aperture is one independent predictor for weight regain after Roux-en-Y gastric bypass. Transoral outlet reduction (TORe) has proven safe and effective for treatment of weight regain by using a superficial-thickness (ST) suturing device. Full-thickness (FT) suturing devices are now available, potentially providing more effective results.ObjectiveTo compare effectiveness of superficial-thickness with full-thickness TORe.DesignMatched cohort study: patients were matched sequentially by GJ anastomosis aperture, body mass index, and age.SettingTertiary-care center.PatientsA total of 59 consecutive patients undergoing full-thickness TORe were matched with 59 patients undergoing superficial-thickness TORe. All had GJ anastomosis apertures >20 mm.InterventionTransoral outlet reduction.Main outcome measurementsWeight loss and rate of adverse events.ResultsPost-TORe GJ anastomosis apertures were similar between groups (ST 6.9 ± 0.2 mm vs FT 7.1 ± 0.3 mm). Weight loss was greater at 6 months in the FT group (10.6 ± 1.8 kg in FT vs 4.4 ± 0.8 kg in ST; P < .01) and at 1 year (8.6 ± 2.5 kg in FT vs 2.9 ± 1.0 kg in ST; P < .01). Excess weight loss was greater in the FT group at 6 months (20.4 ± 3.3% in FT vs 8.1 ± 2.5% in ST; P < .01) and at 1 year (18.9 ± 5.4% in FT vs 9.1 ± 2.3% in ST; P = .03).LimitationsThis was a single-center, retrospective, cohort study.ConclusionThere is level 1b evidence for effectiveness of TORe by using a superficial mucosal suturing device. This matched cohort study compared TORe by using the same ST suturing device with TORe by using a newer, FT suturing device and the same operative methods. FT TORe resulted in significantly more weight loss than ST TORe at 6 months and at 1 year. Full-thickness TORe is a significant improvement over ST TORe for endoscopic therapy of weight regain in patients with dilated GJ anastomosis.

Project description:With advancements in arthroscopic surgery, arthroscopic biceps tenodesis with suture anchor recently has been reported to be a reasonable option for the treatment of biceps pathologies, especially for those that are symptomatic or accompanied by a rotator cuff tear. We introduce our technique of arthroscopic biceps tenodesis with suture anchor that we call the loop-suture technique, which is constructed with 1 loop strand and another sutured strand. This technique can help to improve biceps grip and simultaneously minimize longitudinal splitting of the tendon. In addition, it is relatively simple and can be performed with the use of conventional devices and arthroscopic portals used for rotator cuff repair, without the formation of additional portals or a separate incision for the tenodesis.
