BACKGROUND:Surgeons are trained as "internists that also operate," bringing an important skillset to patient management during the current COVID-19 pandemic. A review was performed to illustrate the response of surgical staff during the pandemic with regard to patient care and residency training. METHODS:The evaluation and assessment of the changes enacted at Stony Brook Medicine's Department of Surgery is illustrated through the unique perspective of surgical residents. No IRB approval or written consent was obtained nor it was necessary for the purposes of this paper. RESULTS:Hospital policy was enacted to hinder transmission of COVID-19 and included limited gatherings of people, restricted travel, quarantined symptomatic staff, and careful surveillance for disease incidence. Surgical residency transformed as residents were diverted from traditional surgical services to staff new COVID-19 ICUs. Education transitioned to an online-based platform for lectures and reviews. New skills sets were acquired such as PICC line placement and complex ventilator management. CONCLUSIONS:The viral surge impacted surgical training while also providing unique lessons regarding preparedness and strategic planning for future pandemic and disaster management.

BACKGROUND:Surgical training includes the development of technical and nontechnical skills. While technical skills are more easily quantified, nontechnical skills such as situation awareness (SA) are more difficult to measure and quantify. This study investigated the relationships between different SA elements and expertise. METHODS:Twenty attending and resident surgeons rated their anticipation of an impending adverse event while watching 20 videos of laparoscopic cholecystectomies with and without adverse events. After watching each video, they assessed surgeon skills and self-assessed their anticipation ratings. All participants answered a general confidence questionnaire before and after the study. RESULTS:Videos with adverse events led to significantly higher anticipation of adverse events (P < 0.001), lower surgeon skill rating (P < 0.001), and higher self-assessment in their anticipation ratings (P < 0.001) across both participant groups. General confidence was significantly lower for residents than that for attending surgeons (P < 0.001). Compared with the residents, attendings exhibited stronger and more stable correlations between measurements of SA. When viewing videos with adverse events, attendings showed significantly higher correlation between anticipation of an impending adverse event and skill assessment of the surgeon (P = 0.005). CONCLUSIONS:This study investigated how different elements of SA and their relationships were influenced by experience. The results indicated that attendings had stronger and more stable correlations between SA elements than residents, demonstrating how measurement correlations could be meaningful and sensitive indicators of expertise and autonomy readiness.

BACKGROUND:Eye-gaze metrics derived from areas of interest (AOIs) have been suggested to be effective for surgical skill assessment. However, prior research is mostly based on static images and simulated tasks that may not translate to complex and dynamic surgical scenes. Therefore, eye-gaze metrics must advance to account for changes in the location of important information during a surgical procedure. METHODS:We developed a dynamic AOI generation technique based on eye gaze collected from an expert viewing surgery videos. This AOI updated as the gaze of the expert moved with changes in the surgical scene. This technique was evaluated through an experiment recruiting a total of 20 attendings and residents to view 10 videos associated with and another 10 without adverse events. RESULTS:Dwell time percentage (i.e., gaze duration) inside the AOI differentiated video type (U = 13508.5, p < 0.001) between videos with the presence (Mdn = 16.75) versus absence (Mdn = 19.95) of adverse events. This metric also differentiated participant group (U = 14029.5, p < 0.001) between attendings (Mdn = 15.45) and residents (Mdn = 19.80). This indicates that our dynamic AOIs reflecting the expert eye gaze was able to differentiate expertise, and the presence of unexpected adverse events. CONCLUSION:This dynamic AOI generation technique produced dynamic AOIs for deriving eye-gaze metrics that were sensitive to expertise level and event characteristics.

OBJECTIVE:With recent changes to graduate medical education, the balance between resident autonomy and need for supervision impacts the educational and training experience of residents. The objective of this study was to understand the relationship between the confidence of attendings and residents and their different perspectives of perceived educational experience and autonomy in the operating room (OR). We hypothesized that the attending's confidence in the resident would be an important factor in improving the educational experience and resident's autonomy in the OR. DESIGN/METHODS:Self-reported confidence-rating and operative experience surveys were administered to teams of post-graduate year (PGY 1) through PGY 5 surgical residents and attendings in two temporal sets (Early: Sept-Dec 2015, n = 20; Late: Jan-Apr 2016, n = 22). A second "end-of-year" survey was distributed to residents (n = 9, 37.5% response) and attendings (n = 10, 35% response) asking questions regarding their educational experience and operative experience during the past year. SETTING/METHODS:Large rural teaching hospital. PARTICIPANTS/METHODS:Nineteen general surgery residents (PGY 1 - 5) and 14 general surgery attendings. RESULTS:Resident perception of confidence differs from junior to senior residents, and that there was discordance between resident's confidence and skill as perceived by attendings, particularly in senior residents. Results also showed that attending's confidence in residents was positively correlated with attending's perceived educational experience in the OR. Residents and attendings both indicated attending's confidence in residents as an important factor in increasing resident autonomy in the OR, thus the attending's confidence in residents could have a positive impact on resident autonomy and educational experience in the OR. CONCLUSIONS:We have demonstrated a relationship between self-confidence for residents and improved confidence from attendings in residents' capabilities. Based on these findings, we would propose identifying methods to expand resident's awareness of surgical situations and develop attending's confidence in residents.
