Introduction: Emergency department thoracotomy (EDT) must be rapid and well-executed. Currently there are no defined benchmarks for EDT procedural milestones. We hypothesized that trauma video review (TVR) can be used to define the 'normative EDT' and generate procedural benchmarks. As a secondary aim, we hypothesized that data collected by TVR would have less missingness and bias than data collected by review of the Electronic Medical Record (EMR)., Methods: We used continuously recording video to review all EDTs performed at our centre during the study period. Using skin incision as start time, we defined four procedural milestones for EDT: 1. Decompression of the right chest (tube thoracostomy, finger thoracostomy, or clamshell thoracotomy with transverse sternotomy performed in conjunction with left anterolateral thoracotomy) 2. Retractor deployment 3. Pericardiotomy 4. Aortic Cross-clamp. EDTs with any milestone time ≥ 75 th percentile of time or during which a milestone was omitted were identified as outliers. We compared rates of missingness in data collected by TVR and EMR using McNemar's test., Results: 44 EDTs were included from the study period. Patients had a median age of 30 [IQR 25-44] and were predominantly African-American (95%) males (93%) with penetrating trauma (95%). From skin incision, median times in minutes to milestones were as follows: right chest decompression: 2.11 [IQR 0.68-2.83], retractor deployment 1.35 [IQR 0.96-1.85], pericardiotomy 2.35 [IQR 1.85-3.75], aortic cross-clamp 3.71 [IQR 2.83-5.77]. In total, 28/44 (64%) of EDTs were either high outliers for one or more benchmarks or had milestones that were omitted. For all milestones, rates of missingness for TVR data were lower than EMR data (p < 0.001)., Conclusions: Video review can be used to define normative times for the procedural milestones of EDT. Steps exceeding the 75 th percentile of time were common, with over half of EDTs having at least one milestone as an outlier. Data quality is higher using TVR compared to EMR collection. Future work should seek to determine if minimizing procedural technical outliers improves patient outcomes., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Background: Quick and successful vascular access in injured patients arriving in extremis is crucial to enable early resuscitation and rapid OR transport for definitive repair. We hypothesized that intraosseous (IO) access would be faster and have higher success rates than peripheral intravenous (PIV) or central venous catheters (CVCs)., Methods: High-definition video recordings of resuscitations for all patients undergoing emergency department thoracotomy from April 2016 to July 2017 were reviewed as part of a quality improvement initiative. Demographics, mechanism of injury, access type, access location, start and stop time, and success of each vascular access attempt were recorded. Times to completion for access types (PIV, IO, CVC) were compared using Kruskal-Wallis test adjusted for multiple comparisons, while categorical outcomes, such as success rates by access type, were compared using χ test or Fisher's exact test., Results: Study patients had a median age of 30 years (interquartile range [IQR], 25-38 years), 92% were male, 92% were African American, and 93% sustained penetrating trauma. A total of 145 access attempts in 38 patients occurred (median, 3.8; SD, 1.4 attempts per patient). There was no difference between duration of PIV and IO attempts (0.63; IQR, 0.35-0.96 vs. 0.39 IQR, 0.13-0.65 minutes, adjusted p = 0.03), but both PIV and IO were faster than CVC attempts (3.2; IQR, 1.72-5.23 minutes; adjusted p < 0.001 for both comparisons). Intraosseous lines had higher success rates than PIVs or CVCs (95% vs. 42% vs. 46%, p < 0.001)., Conclusion: Access attempts using IO are as fast as PIV attempts but are more than twice as likely to be successful. Attempts at CVC access in patients in extremis have high rates of failure and take a median of over 3 minutes. While IO access may not completely supplant PIVs and CVCs, IO access should be considered as a first-line therapy for trauma patients in extremis., Level of Evidence: Therapeutic, level III.

Communicating service-specific practice patterns, guidelines, and provider information to a new team of learners that rotate frequently can be challenging. Leveraging individual and healthcare electronic resources, a mobile device platform was implemented into a newly revised resident onboarding process. We hypothesized that offering an easy-to-use mobile application would improve communication across multiple disciplines as well as improve provider experiences when transitioning to a new rotation. A mobile platform was created and deployed to assist with enhancing communication within a trauma service and its resident onboarding process. The platform had resource materials such as: divisional policies, Clinical Practice Guidelines (CMGs), and onboarding manuals along with allowing for the posting of divisional events, a divisional directory that linked to direct dialing, text or email messaging, as well as on-call schedules. A mixed-methods study, including an anonymous survey, aimed at providing information on team member's impressions and usage of the mobile application was performed. Usage statistics over a 3-month period were analyzed on those providers who completed the survey. After rotation on the trauma service, trainees were asked to complete an anonymous, online survey addressing both the experience with, as well as the utility of, the mobile app. Thirty of the 37 (81%) residents and medical students completed the survey. Twenty-five (83%) trainees stated that this was their first experience rotating on the trauma service and 6 (20%) were from outside of the health system. According to those surveyed, the most useful function of the app were access to the directory (15, 50%), the divisional calendar (4, 13.3%), and the on-call schedules (3, 10%). Overall, the app was felt to be easy to use (27, 90%) and was accessed an average of 7 times per day (1-50, SD 9.67). Over half the survey respondents felt that the mobile app was helpful in completing their everyday tasks (16, 53.3%). Fifteen (50%) of the respondents stated that the app made the transition to the trauma service easier. Twenty-five (83.3%) stated it was valuable knowing about departmental events and announcements, and 17 (56.7%) felt more connected to the division. The evolution of mobile technology is rapidly becoming fundamental in medical education and training. We found that integrating a service-specific mobile application improved the learner's experience when transitioning to a new service and was a valuable onboarding instrument.

The intraosseous (IO) access initiative at an urban university adult level 1 trauma center began from the need for a more expeditious vascular access route to rescue patients in extremis. The goal of this project was a multidisciplinary approach to problem solving to increase access of IO catheters to rescue patients in all care areas. The initiative became a collaborative effort between nursing, physicians, and pharmacy to embark on an acute care endeavor to standardize IO access. This is a descriptive analysis of processes to effectively develop collaborative strategies to navigate hospital systems and successfully implement multilayered initiatives. Administration should empower nurse to advance their practice to include IO for patient rescue. Intraosseous access may expedite resuscitative efforts in patients in extremis who lack venous access or where additional venous access is required for life-saving therapies. Limiting IO dwell time may facilitate timely definitive venous access. Continued education and training by offering IO skill laboratory refreshers and annual e-learning didactic is optimal for maintaining proficiency and knowledge. More research opportunities exist to determine medication safety and efficacy in adult patients in the acute care setting.
