Curriculum Using the In-Situ Operating Room Setting.

OBJECTIVE: The American College of Surgeons/Association of Program Directors in Surgery is a comprehensive, simulation-based curriculum for General Surgery residents which exists in 3 phases. While phases 1 and 2 deal with core skills and advanced procedures respectively, phase 3 targets team-based skills. To date, the 3rd phase of this curriculum has not seen wide scale implementation. This is a pilot study to verify the feasibility of implementing the phase 3 curriculum in the in-situ setting. DESIGN: In our initial attempt to implement Phase 3 at our institution, we chose to perform the training in an in-situ setting within an operating room (OR) at our main hospital, despite our having a separate simulation center. By choosing the in-situ OR environment for this training we were able to minimize concerns regarding resident and faculty availability and able to successfully complete 8 separate sessions during the academic year. During 7 sessions, 2 separate scenarios were performed while a single scenario was performed in 1 session. This single session was excluded from analysis, leaving a total of 14 scenarios to evaluate. The unique scenarios included laparoscopic crisis, postoperative myocardial infarction, anaphylaxis, and postoperative hypotension. All sessions were audiovisually recorded. In order to evaluate the effect of the training, the videos were viewed by 3 independent reviewers and all surgery, anesthesia and nursing participants were rated using the NOTECHs II scale. Degree of inter-rater agreement was established. The difference between the first and second simulations on the same day was then assessed. In addition, participant opinions of the simulations were assessed through electronic surveys following the training. SETTING: Tertiary Care University Hospital. PARTICIPANTS: We performed a total of 8 sessions, for a total of 15 scenarios. Eight surgery residents at the postgraduate year 1 (PGY1)-PGY3 level, 16 anesthesia residents at the PGY3-PGY4 level, 16 nurses and 13 ancillary staff participated. RESULTS: From the first to the second scenario, the total team NOTECHs II score increased from 69.4 ± 1.4 to 77.3 ± 0.5 (p = 0.007). The NOTECHs II scores for each subteam also improved, from 24.2 ± 0.6 to 26.4 ± 0.5 (p = 0.007) for surgery residents, 23.7 ± 0.9 to 26.7 ± 0.4 (p = 0.03) for anesthesia, and 21.6 ± 0.3 to 24.3 ± 0.5 (p = 0.01) for nursing. The inter-rater reliability as measured by Kendall's coefficient of concordance was modest for the whole team score. Most of the participant responses were either favorable or strongly favorable. CONCLUSION: The in-situ OR environment is both a unique and effective setting to perform team-based training. Furthermore, training in the in-situ setting minimizes or removes many of the logistic issues involved in designing and implementing team-based training curricula for general surgery residency programs. However, we found that administrative and departmental (surgery, anesthesia, and nursing) "buy in" as well as protected faculty time for education were all necessary for in-situ training to be successful. NOTECHs II is an established scale for the evaluation of teams in this simulation setting and appears to be a valid tool based on the results of this study. However, further assessment of inter-rater reliability as well as improved training of evaluators are necessary to determine if inter-rater reliability can improve.

Managing a surgical exsanguination emergency in the operating room through simulation: an interdisciplinary approach.

OBJECTIVE: Operating room (OR) emergencies, such as fire, anaphylaxis, cardiac arrest, and exsanguination, are infrequent, but high-risk situations that can result in significant morbidity and mortality. An exsanguination scenario involving a pregnant trauma patient in the OR was developed for surgery residents with the objectives of improving overall team performance when activating an emergency response system, identifying a team leader, initiating an exsanguination protocol, following advanced cardiac life support guidelines, and recognizing the mother as the first patient. STUDY DESIGN: During 6 months, 171 OR staff members of the Hospital of the University of Pennsylvania participated in a prospective study in which randomly selected groups of surgery residents, anesthesia residents, and perioperative nurses were trained in a simulated exsanguination and cardiac arrest emergency. Upon arrival to the simulation center, groups of trainees were assigned to a simulated OR equipped with a SimMan 3G (Laerdal, Norway) and a session moderator. The scenario started with a pregnant patient in hemorrhagic shock, bleeding from a carotid injury, ultimately leading to cardiac arrest. Each group did an initial "cold" simulation without any prior training or knowledge of the scenario, followed by a didactic training session, and ending with a "warm" simulation. SETTING: Penn Medicine Clinical Simulation Center at 1800 Lombard Street, Philadelphia, Pennsylvania. RESULTS: Among 156 participants, 50% reported understanding their role in an OR exsanguination emergency pretraining, compared with 98% who understood it posttraining (p < 0.001). For activation of the exsanguination protocol, 50% understood how to do it pretraining, compared with 98% posttraining (p = 0.004). The time needed to complete 8 clinically significant tasks was documented pre- and posttraining, with a statistically significant improvement in all tasks. CONCLUSIONS: The results of this simulated exsanguination emergency demonstrate that team training using a high-fidelity mannequin is an effective way to train OR personnel, on how to manage exsanguinating traumatic patients in a high-risk surgical emergency.
