Objectives: The purpose of this study was to critically evaluate the quality, reliability and educational content of the information of vital pulp treatment videos available on YouTube. Materials and Methods: The keywords "pulpotomy" and "pulp capping" were searched on YouTube on 5th July 2020, until 60 English language videos of each search term with a duration shorter than 15 minutes were acquired. Video characteristics were recorded and Video Power Index (VPI) was calculated. Reliability and educational quality of videos were evaluated using the Modified DISCERN score, the Journal of American Medical Association (JAMA) benchmark criteria and Global Quality Scores (GQS). Videos were categorized by uploading source. Results: Regarding pulpotomy, 31.7% of the videos were uploaded by specialists and 68.3% were directed by non-specialists. In the case of pulp capping, the corresponding percentages were 45% and 55%, respectively. Videos uploaded by specialists had significantly higher modified DISCERN, JAMA and GQS scores compared to those uploaded by non-specialists. Endodontists tended to have the highest reliability and VPI scores. Conclusions: YouTube videos on vital pulp treatment contain low educational quality or incomplete information. Low popularity of dental pulp capping and pulpotomy videos may be attributed to the specialized nature of these procedures. As YouTube represents an important source for patient information about different health topics, reliable informative videos should be uploaded by specialized dental professionals.

Recently, many studies have introduced artificial intelligence systems in the surgical process to reduce the incidence and mortality of complications in patients. Bleeding is a major cause of operative mortality and complications. However, there have been few studies conducted on detecting bleeding in surgical videos. To advance the development of deep learning models for detecting intraoperative hemorrhage, three models have been trained and compared; such as, YOLOv5, RetinaNet50, and RetinaNet101. We collected 1,016 bleeding images extracted from five surgical videos. The ground truths were labeled based on agreement from two specialists. To train and evaluate models, we divided the datasets into training data, validation data, and test data. For training, 812 images (80%) were selected from the dataset. Another 102 images (10%) were used for evaluation and the remaining 102 images (10%) were used as the evaluation data. The three main metrics used to evaluate performance are precision, recall, and false positive per image (FPPI). Based on the evaluation metrics, RetinaNet101 achieved the best detection results out of the three models (Precision rate of 0.99±0.01, Recall rate of 0.93±0.02, and FPPI of 0.01±0.01). The information on the bleeding detected in surgical videos can be quickly transmitted to the operating room, improving patient outcomes.

Purpose: This study tested the effectiveness of brochure- and video-based education on managing surgical site infections by operating room health personnel. Methods: From April 20 to May 4, 2021, 34 operating room health personnel were subjected to training on surgical site infection management using brochures and educational videos. A survey was then conducted on knowledge, perception, and adherence regarding surgical site infection management. Results: After receiving training on surgical site infection management, the knowledge score increased significantly (15.15±2.09 vs.19.70±1.96, p<.001). However, the perception and adherence scores were already near perfect before the intervention and did not further increase after the intervention. Conclusion: It is necessary to develop and utilize continuous and substantive educational programs to improve perception and adherence of surgical site infection management.

Background: Reverse shoulder arthroplasty (RSA) has evolved continuously over recent years, with expanded indications and better outcomes. YouTube is one of the most popular sources globally for health-related information available to patients. Evaluating the reliability of YouTube videos concerning RSA is important to ensure proper patient education. Methods: YouTube was queried for the term "reverse shoulder replacement." The first 50 videos were evaluated using three different scores: Journal of the American Medical Association (JAMA) benchmark criteria, the global quality score (GQS), and the reverse shoulder arthroplasty-specific score (RSAS). Multivariate linear regression analyses were conducted to determine the presence of a relationship between video characteristics and quality scores. Results: The average number of views was 64,645.78±264,160.9 per video, and the average number of likes was 414 per video. Mean JAMA, GQS, and RSAS scores were 2.32±0.64, 2.31±0.82, and 5.53±2.43, respectively. Academic centers uploaded the highest number of videos, and surgical techniques/approach videos was the most common video content. Videos with lecture content predicted higher JAMA scores whereas videos uploaded by industry predicted lower RSAS scores. Conclusions: Despite its massive popularity, YouTube videos provide a low quality of information on RSA. Introducing a new editorial review process or developing a new platform for patients' medical education may be necessary. Level of evidence: Not applicable.

Background: YouTube has become a popular source of healthcare information in orthopedic surgery. Although quality-based studies of YouTube content have been performed for information concerning many orthopedic pathologies, the quality and accuracy of information on the rotator cuff have yet to be evaluated. The purpose of the current study was to evaluate the reliability and educational content of YouTube videos concerning the rotator cuff. Methods: YouTube was queried for the term "rotator cuff." The first 50 videos from this search were evaluated. Video reliability was assessed using the Journal of the American Medical Association (JAMA) benchmark criteria (range, 0-5). Educational content was assessed using the global quality score (GQS; range, 0-4) and the rotator cuff-specific score (RCSS; range, 0-22). Results: The mean number of views was 317,500.7±538,585.3. The mean JAMA, GQS, and RCSS scores were 2.7±2.0, 3.7±1.0, and 5.6±3.6, respectively. Non-surgical intervention content was independently associated with a lower GQS (β=-2.19, p=0.019). Disease-specific video content (β=4.01, p=0.045) was the only independent predictor of RCSS. Conclusions: The overall quality and educational content of YouTube videos concerned with the rotator cuff were low. Physicians should caution patients in using such videos as resources for decision-making and should counsel them appropriately.

Background: While online orthopedic resources are becoming an increasingly popular avenue for patient education, videos on YouTube are not subject to peer review. The purpose of this cross-sectional study was to evaluate the quality of YouTube videos for patient education in ulnar collateral ligament (UCL) injuries of the elbow. Methods: A search of keywords for UCL injury was conducted through the YouTube search engine. Each video was categorized by source and content. Video quality, reliability, and accuracy were assessed by two independent raters using five metrics: (1) Journal of American Medical Association (JAMA) benchmark criteria (range 0-4) for video reliability; (2) modified DISCERN score (range 1-5) for video reliability; (3) Global Quality Score (GQS; range 1-5) for video quality; (4) ulnar collateral ligament-specific score (UCL-SS; range 0-16), a novel score for comprehensiveness of health information presented; and (5) accuracy score (AS; range 1-3) for accuracy. Results: Video content was comprised predominantly of disease-specific information (52%) and surgical technique (33%). The most common video sources were physician (42%) and commercial (23%). The mean JAMA score, modified DISCERN score, GQS, UCL-SS, and AS were 1.8, 2.4, 1.9, 5.3, and 2.7 respectively. Conclusions: Overall, YouTube is not a reliable or high-quality source for patients seeking information regarding UCL injuries, especially with videos uploaded by non-physician sources. The multiplicity of low quality, low reliability, and irrelevant videos can create a cumbersome and even inaccurate learning experience for patients.

Artificial intelligence (AI) has made significant progress in recent years, and many medical fields are attempting to introduce AI technology into clinical practice. Currently, much research is being conducted to evaluate that AI can be incorporated into surgical procedures to make them safer and more efficient, subsequently to obtain better outcomes for patients. In this paper, we review basic AI research regarding surgery and discuss the potential for implementing AI technology in gastric cancer surgery. At present, research and development is focused on AI technologies that assist the surgeon's understandings and judgment during surgery, such as anatomical navigation. AI systems are also being developed to recognize in which the surgical phase is ongoing. Such a surgical phase recognition systems is considered for effective storage of surgical videos and education, in the future, for use in systems to objectively evaluate the skill of surgeons. At this time, it is not considered practical to let AI make intraoperative decisions or move forceps automatically from an ethical standpoint, too. At present, AI research on surgery has various limitations, and it is desirable to develop practical systems that will truly benefit clinical practice in the future.

Purpose: The purpose of this study was to examine the effects of preoperative pain management education on postoperative pain control in patients with uterine tumor using patient controlled analgesia. Methods: This study used non-equivalent control group non-synchronized design. Data were collected from September, 2008 to March, 2009 at one university hospital in Daegu, Korea. There were 60 participants, 30 in both the experimental and control group. The experimental group was given preoperative pain education using videos, leaflets, and a PCA model. Postoperative pain intensity, frequency of the PCA button being pressed, and doses of additional analgesics were observed through 24 hours postoperative and knowledge of pain and attitude about the use of the pain medicine were measured at 3 days postoperative. Collected data were analyzed using t-test, ${\chi}^2$ test, repeat measured ANOVA, and Bonferroni methods. Results: There were no significant differences in the postoperative pain level between the experimental and control group. Postoperative frequency of the PCA button pressed, doses of additional analgesics, pain knowledge and attitude about the use of the pain medicine of the experimental group were significantly higher than those of the control group. Conclusion: Pain management education is an effective nursing intervention for pain control after surgery.

The purpose of this GWP project was two-fold:(1) to launch an organizational culture improvement for great workplace (2) to improve the perception of nursing personnel on communication and team work in a surgical nursing department of a teaching hospital in Seoul. Using one group pretest-posttest design, nursing personnel's perception on organizational culture related to communication and team work was evaluated. A 10-item, 5-point scale (1.5) survey was administered to 209 nursing personnel in January 2009 and again to 191 nursing personnel in October 2009. From January 2009, AMANNA team has taken activities focused on trust, pride, and fun. AMANNA is an abbreviation of Korean language, which means wonderful meeting and sharing in English. Monthly activities are as follows: choral concerts by nurse managers, welcome and farewell events, praising members for their services, explaining current circumstances, etc. Special activities are as follows: a New Year's greeting party, a spring picnic, beauty classes, a lecture on drug administration, cultural lectures using videos, and presentations of academic posters and another activity. The reliability of measurement was Cronbach's ${\alpha}$: 0.917(pretest), 0.954(posttest). Most nursing personnel's perception on organizational culture was improved (pretest mean=3.50 and posttest mean=3.78, p<.001). "A sense of belonging" showed the greatest improvement among the 10 items(3.18 vs. 3.56, p<.001). "Trust each other" showed the highest score (mean=3.98) in posttest. Frequency of participation and satisfaction showed a significant relationship(r=0.179, p=.021). We believe that this project has made a contribution towards a positive organizational culture. The keys to this initiative's preliminary success have been the leadership support and flexibility in implementing the interventions tailored to the hospital.
