Does Perceived Resident Operative Autonomy Impact Patient Outcomes?

OBJECTIVE: We investigated the association of perceived trainee autonomy with patient clinical outcomes following colorectal surgery. DESIGN: This was a prospective multi-institutional study that consisted of surgery trainees completing a survey tool immediately after participating in colorectal resections to rate their self-perceived autonomy and case characteristics. Self-perception of autonomy was classified as observer, assistant, surgeon, or teacher. The completed trainee surveys were linked with patient information available through each hospital's internal NSQIP directory. The primary outcome was death and serious morbidity (DSM) and secondary outcome was 30-day readmissions. Separate mixed effects regression models were used to examine the association between perceived trainee autonomy and DSM or 30-day readmissions. Fixed effects were used to control for the effects of the training environment. The models were constructed to adjust for patient and trainee characteristics associated with each outcome independently. SETTING: This study was conducted at 7 general surgery training programs (5 academic medical centers and 2 independent training programs) with general surgery or colorectal surgery services. PARTICIPANTS: This study included a total of 63 residents and fellows rotating on surgery services that performed colorectal resections at the included 7 general surgery training programs from January until March 2016. RESULTS: The 63 trainees that participated in this study completed 417 surveys with over a 95% response rate. National Surgical Quality Improvement Program (NSQIP) patient records were available for 67% (n = 273) of completed surveys. The clinical year of the trainees were 6.1% PGY 1/2, 36% Post graduate year (PGY) 3, 40.9% PGY 4/5, and 17% fellows. Residents perceived their participation in the case to be that of an observer in 9.2% of surveys, an assistant in 51.6% of surveys, and the surgeon/teacher in 39.3% of surveys. About 50% of patients were male, 80% were White, the majority had an American Society of Anesthesiologists classification of 3, almost half had prior abdominal surgery, and over 80% of surgeries were elective. The primary operation types performed were laparoscopic (40.3%) and open (35.9%) partial colectomies. The rate of DSM in patients was approximately 24% when trainees perceived their role as observers, 23% when trainees perceived their role as assistants, and 18% when trainees perceived their role as surgeons/teachers. After adjustment for patient, trainee, and training environment, we found that the perceived level of trainee autonomy of a surgeon/teacher was associated with a 4-fold lower rate of DSM (odds ratio: 0.23, confidence of interval: 0.05-0.97, p = 0.045) compared to observers. The rate of readmissions was approximately 20% when trainees perceived their role as observers, 14% when trainees perceived their role as assistants and 9% when trainees perceived their role as surgeons/teachers. After adjustment for patient, trainee, and training environment, we found that the perceived level of trainee autonomy of a surgeon/teacher was significantly associated with a 10-fold lower rate of 30-day readmissions (odds ratio: 0.09, confidence of interval: 0.01-0.70, p = 0.022) compared to observers. CONCLUSIONS: There was an association between increased perceived trainee autonomy and improved patient outcomes, suggesting that when trainees identify with an increased role in the operation, patients may have improved care. Further research is needed to understand this association further.

Absorbable Antibiotic Beads Prophylaxis in Immediate Breast Reconstruction.

BACKGROUND: Breast reconstruction with tissue expanders is the most common mode of reconstruction following mastectomy. Infection necessitating tissue expander removal is a significant complication leading to patient distress and increased health care costs. METHODS: Over 3 years, 127 breast reconstructions with tissue expanders were performed by a single surgeon. Fifty-nine of these reconstructions were performed using a standardized protocol in which patients washed with chlorhexidine several days before surgery and received intravenous antibiotics preoperatively. Intraoperatively, the submuscular pocket was irrigated with triple-antibiotic solution and the skin was prepared again with povidone-iodine before expander placement. This group was referred to as the preintervention group. Sixty-eight of the reconstructions were performed using the standardized protocol with the addition of biodegradable antibiotic beads (Stimulan with vancomycin and gentamicin) in the submuscular pocket. This group made up the postintervention group. The primary outcome was the rate of infection necessitating tissue expander removal. RESULTS: The rate of tissue expander loss caused by infection was 11.9 percent in the preintervention group and 1.5 percent in the postintervention group (p = 0.024). Higher body mass index was associated with a statistically significant increase in infections necessitating expander removal. CONCLUSION: The use of absorbable antibiotic beads in the submuscular pocket reduced the risk of periprosthetic implant infection necessitating implant removal by 8-fold. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Quantification of Resident Work in Colorectal Surgery.

OBJECTIVE: To examine resident intraoperative participation, perceived autonomy, and communication patterns between residents and attending surgeons using a novel survey tool. DESIGN: This was a prospective multi-institutional study. Operative residents completed the survey tool immediately after each colorectal resection performed during the study period. Resident intraoperative participation was quantified including degree of involvement in the technical aspects of the case, self-perception of autonomy, and communication strategies between the resident and attending. SETTING: This study was conducted at 7 general surgery residency programs: 5 academic medical centers, and 2 independent training programs. PARTICIPANTS: Residents and fellows rotating on a colorectal surgery service or general surgery service. RESULTS: Sixty-three residents participated in this study with 417 surveys completed (range 19-79 per institution) representing a 95.4% response rate across all sites. Respondents ranged from clinical year 1 (CY1) to fellows. CY3s (35.7%) and CY5s (34.7%) were most heavily represented. Residents completed ≥50% of the skin closure in 88.7% of cases, ≥50% of the fascial closure in 87.1%, and t ≥ 50% of the anastomosis in 78.4% of the cases. Increasing resident participation was associated with advancing resident CY across all technical aspects of the case. This trend remained significant when controlling for site (p < 0.001). Resident self-perception of autonomy revealed learners of all stages: Observer (11.5%, n = 48), Assistant (53.7%, n = 224), Surgeon (33.8%, n = 141), and Teacher (0.96%, n = 4). Level of perceived autonomy increased with resident CY when controlling for site (p < 0.001). Residents who discussed the case before the day of surgery were twice as likely to rate themselves as Surgeon or Teacher (OR = 2.01) when controlling for CY (p = 0.011). CONCLUSIONS: Brief surveys can easily capture resident work in the operating room. Resident intraoperative involvement and perceived autonomy are associated with CY. Early communication with the attending is significantly associated with increased perception of autonomy regardless of CY.

Are They Too Old for Surgery? Safety of Cholecystectomy in Superelderly Patients (≥ Age 90).

CONTEXT: Cholecystectomy is the most common general surgery procedure in patients older than age 65 years. By 2050, it is estimated that 2.0% of the population will be older than age 90 years. OBJECTIVE: To assess the mortality of cholecystectomy in superelderly patients (≥ age 90 years). DESIGN: Using the American College of Surgeons National Surgical Quality Improvement Program database, a retrospective analysis was performed of superelderly patients who underwent laparoscopic and open cholecystectomy between 2005 and 2012. MAIN OUTCOME MEASURES: Thirty-day mortality. RESULTS: A total of 1007 cholecystectomies were performed in superelderly patients between 2005 and 2012. Of these surgical procedures, 807 (80%) were nonemergent and 200 (20%) were performed emergently. Two hundred sixteen procedures (21.4%) were open and 791 (78.6%) were laparoscopic. Mortality did not decrease significantly during the study period. The overall mortality was 5.5%, significantly less for the laparoscopic group (3.7% vs 12%, p < 0.001) and for the nonemergent group (4.5% vs 9.5%, p < 0.005). The median length of stay for open cholecystectomy was 9 days compared with 5 days for laparoscopic (p < 0.001); for nonemergent cholecystectomy it was 5 days compared with 7 days for emergent cholecystectomy (p < 0.001). CONCLUSION: The mortality after cholecystectomy in superelderly patients did not change significantly during the study period. The mortality and morbidity for laparoscopic and elective procedures were significantly lower than for open procedures and for emergent procedures, respectively.
