Critical errors in infrequently performed trauma procedures after training

Advanced Surgical Skills for Exposure in Trauma (ASSET) course improves military surgeon confidence

OBJECTIVE

Active duty military surgeons often have limited trauma surgery experience prior to deployment. Consequently, military-civilian training programs have been developed at high-volume trauma centers to evaluate and maintain proficiencies. Advanced Surgical Skills for Exposure in Trauma (ASSET) was incorporated into the predeployment curriculum at the Army Trauma Training Detachment in 2011. This is the first study to assess whether military surgeons demonstrated improved knowledge and increased confidence after taking ASSET.

DESIGN

Retrospective cohort study.

SETTING

Quaternary care hospital.

PATIENTS AND PARTICIPANTS

Attending military surgeons who completed ASSET between July 2011 and October 2020.

MAIN OUTCOME MEASURE(S)

Pre- and post-course self-reported comfort level with procedures was converted from a five-point Likert scale to a percentage and compared using paired t-tests.

RESULTS

In 188 military surgeons, the median time in practice was 3 (1-8) years, with specialties in general surgery (52 percent), orthopedic surgery (29 percent), trauma (7 percent), and other disciplines (12 percent). The completed self-evaluation response rate was 80 percent (n = 151). The self-reported comfort level for all body regions improved following course completion (p < 0.001): chest (27 percent), neck (23 percent), upper extremity (22 percent), lower extremity (21 percent), and abdomen/pelvis (19 percent). The overall score on the competency test improved after completion of ASSET, with averages increasing from 62 ± 18 percent pretest to 71 ± 13 percent post-test (p < 0.001).

CONCLUSIONS

After taking the ASSET course, military surgeons demonstrated improved knowledge and increased confidence in the operative skills taught in the course. The ASSET course may provide sustainment of knowledge and confidence if used at regular intervals to maintain trauma skills and deployment readiness.

The Impact of the Maritime Deployment Cycle on the Surgeon's Knowledge, Skills, and Abilities

INTRODUCTION

The U.S. Navy routinely deploys aircraft carriers and amphibious assault ships throughout the world in support of U.S. strategic interests, each with an embarked single surgeon team. Surgeons and their teams are required to participate in lengthy pre-deployment shipboard certifications before each deployment. Given the well-established relationship of surgeon volume to patient outcome, we aim to compare the impact of land vs. maritime deployments on Navy general surgeon practice patterns.

MATERIALS AND METHODS

Case logs and pre-deployment training initiation of land-based (n = 8) vs. maritime-based (n = 7) U.S. Navy general surgeons over a 3-year period (2017-2020) were compared. Average cases per week were plotted over 26 weeks before deployment. Student's t-test was utilized for all comparisons.

RESULTS

Cases declined for both groups in the weeks before deployment. At 6 months (26 weeks) before deployment, land-based surgeons performed significantly more cases than their maritime colleagues (50.3 vs. 14.0, P = .009). This difference persisted at 16 weeks (13.1 vs. 1.9, P = .011) and 12 weeks (13.1 vs. 1.9, P = .011). Overall, surgeon operative volume fell off earlier for maritime surgeons (16 weeks) than land-based surgeons (8 weeks). Within 8 weeks of deployment, both groups performed a similarly low number of cases as they completed final deployment preparations.

CONCLUSIONS

Surgeons are a critical component of combat causality care teams. In this analysis, we have demonstrated that both land- and maritime-based U.S. Navy surgeons have prolonged periods away from clinical care before and during deployments; for shipboard surgeons, this deficit is large and may negatively impact patient outcomes in the deployed maritime environment. The authors describe this discrepancy and provide practical doctrinal solutions to close this readiness gap.

[Simulations in continuing education for more patient safety : Do simulation and skills training influence patient safety in Germany?]

The secure mastering of manual skills and their regular training lead to a reduction of errors and to an improvement of patient safety. Due to increasing economic pressure and bureaucratization, there is less exposure and insufficient time in the clinical routine to communicate all the contents of continuing education. This is why surgical simulation has become increasingly relevant to improve surgical performance in residents. Nowadays, many forms of simulation training are offered in Germany; however, such training on a model is costly and personnel-intensive. In order to justify the effort, objective measurements are becoming more important to qualify the effectiveness of simulation-based training in Germany.

Impact of Civilian Patient Care on Major Amputation Case Volume in the Military Health System

BACKGROUND

Sustaining critical wartime skills (CWS) during interwar periods is a recurrent and ongoing challenge for military surgeons. Amputation surgery for major extremity trauma is exceptionally common in wartime, so maintenance of surgical skills is necessary. This study was designed to examine the volume and distribution of amputation surgery performed in the military health system (MHS).

STUDY DESIGN

All major amputations performed in military treatment facilities (MTF) for calendar years 2017-2019 were identified by current procedural terminology (CPT) codes. The date of surgery, operating surgeon National Provider Identifier, CPT code(s), amputation etiology (traumatic versus nontraumatic), and beneficiary status (military or civilian) were recorded for each surgical case.

RESULTS

One thousand one hundred and eighty-four major amputations at 16 of the 49 military's inpatient facilities were identified, with two MTFs accounting for 46% (548/1,184) of the total. Six MTFs performed 120 major amputations for the treatment of acute traumatic injuries. Seventy-three percent (87/120) of traumatic amputations were performed at MTF1, with the majority of patients (86%; 75/87) being civilians emergently transported there after injury. Orthopedic and vascular surgeons performed 78% of major amputations, but only 9.7% (152/1,570) of all military surgeons performed any major amputation, with only 3% (52) involved in amputations for trauma. Nearly all (87%; 26/30) of the orthopedic surgeons at MTF1 performed major amputations, including those for trauma.

CONCLUSION

This study highlights the importance of civilian patient care to increase major amputation surgical case volume and complexity to sustain critical wartime skills. The preservation and strategic expansion of effective military-civilian partnerships is essential for sustaining the knowledge and skills for optimal combat casualty care.

Military deployment's impact on the surgeon's practice

BACKGROUND

As the United States withdraws from overseas conflicts, general surgeons remain deployed in support of global operations. Surgeons and surgical teams are foundational to combat casualty care; however, currently, there are few casualty producing events. Low surgical volume and acuity can have detrimental effects on surgical readiness for those frequently deployed. The surgical team cycle of deployment involves predeployment training, drawdown of clinical practice, deployment, postdeployment reintegration, and rebuilding of a patient panel. This study aims to assess these effects on typical general surgeon practices. Quantifying the overall impact of deployment may help refine and implement measures to mitigate the effects on skill retention and patient care.

METHODS

Surgeon case logs of eligible surgeons deploying between January 1, 2017, and January 1, 2020, were included from participating military treatment facilities. Eligible surgeons were surgeons whose case logs were primarily at a single military treatment facility 26 weeks before and after deployment and whose deployment duration, location, and number of deployed cases were obtainable.

RESULTS

Starting 26 weeks prior to deployment, analyzing in 1-week intervals toward deployment time, case count decreased by 4.8% (p < 0.0001). With each 1-week interval, postdeployment up to the 26-week mark, case count increased by 6% (p < 0.0001). Cases volumes most prominently drop 3 weeks prior to deployment and do not reach normal levels until approximately 7 weeks postdeployment. Case volumes were similar across service branches.

CONCLUSION

There is a significant decrease in the number of cases performed before deployment and increase after return regardless of military branch. The perideployment surgical volume decline should be understood and mitigated appropriately; predeployment training, surgical skill retention, and measures to safely reintegrate surgeons back into their practice should be further developed and implemented.

Clinical utilization of deployed military surgeons

BACKGROUND

Combat casualty care has been shaped by the prolonged conflicts in Southwest Asia, namely Afghanistan, Iraq, and Syria. The utilization of surgeons in austere locations outside of Southwest Asia and its implication on skill retention and value have not been examined. This study hypothesizes that surgeon utilization is low in the African theater. This lack of activity is potentially damaging to surgical skill retention and patient care.

METHODS

Military case logs of surgeons deployed to Africa under command of Special Operations Command Africa between January 1, 2016, and January 1, 2020, were examined. Cases were organized based on population served, general type of procedure, current procedural terminology codes, and location.

RESULTS

Twenty deployment caseloads representing 74% of the deployments during the period were analyzed. In 3,294 days, 101 operations were performed, which included 45 on combat/terrorism related injuries and 19 on US personnel. East and West African deployments, combat, and noncombat zones, respectively, were compared. East Africa averaged 4.1 ± 3.8 operations per deployment, and West Africa, 7.3 ± 8.0 (p = 0.2434). In East Africa, 56.1% of total operations were related to combat/terrorism, compared with 29.6% of total operations in West Africa (p = 0.0077). West Africa had a significantly higher proportion of elective (p = 0.0002) and humanitarian cases (p = <0.0001).

CONCLUSION

Surgical cases for military surgeons were uncommon in Africa. The low volumes have implications for skill retention, morale, and sustainability of military surgical end strength. Reduction in deployment lengths, deployment location adjustments, and/or skill retention strategies are required to ensure clinical peak performance and operational readiness. Failure to implement changes to current practices to optimize surgeon experience will likely decrease surgical readiness and could contribute to decreased retention of deployable military surgeons to support global operations.

Quantitative analysis of intermuscular septa in the leg: implications for trauma surgery

Background

Compartment syndrome is the excess swelling within an inelastic compartment leading to excessive compartment pressure. Lower limb trauma has a high risk of compartment syndrome, which is typically mitigated using a two-incision fasciotomy. Our previous findings showed surgeons sometimes perform incomplete fasciotomies due to misidentifying the septum between the lateral and superficial posterior compartments as the septum between the anterior and lateral compartments. We conjectured this may be due to variability in the septal position between individuals leading to misinterpretation of the septal identity.

Methods

A retrospective analysis was performed using CT angiograms to analyze septal position between the anterior and lateral compartments of the leg of 100 patients randomly selected from the University of Maryland Shock Trauma Center database.

Results

Analysis of septal position showed that (1) as the septum progresses distally down the leg, the relative septum position shifts anteriorly; and that (2) there was considerable variability in the intermuscular septum position between individuals even when accounting for the anterior to posterior progression of septal position.

Discussion

This variability could lead to erroneous septal identification in individuals with a very anteriorly located septum during a leg fasciotomy with the classic initial incision being insufficiently anterior. We propose making the lateral initial incision ‘two finger breadths posterior the tibia’ rather than the traditional ‘one finger breadth anterior’ to the fibula. This moves the initial incision slightly anteriorly, uses the more readily palpable tibia, and makes the medial and lateral incisions symmetrical at ‘two finger breadths’ from the tibia, simplifying the procedure.

Variability of Value of Trauma Centers to General Surgery Combat Casualty Care Skill Sustainment

OBJECTIVE

Military-civilian partnerships for the maintenance of trauma readiness skills will be required to maintain skills in preparation for future combat casualty care operations. There is little data describing relative worth of potential partnerships. This study aims to demonstrate that quantitative and qualitative differences are prevalent between trauma centers.

DESIGN

A combat casualty care relevant case (CCC-RC) was determined to be one that was open, urgent, and required a blood transfusion. Total number of urgent trauma cases and number of cases requiring transfusions between January 1, 2017 and January 1, 2019 were tallied at Saint Louis University Hospital (ACS Level 1), San Antonio Military Medical Center (ACS Level 1), Madigan Army Medical Center (Washington Level 2), and William Beaumont Army Medical Center (Texas Level 3). At the participating level 1 trauma centers, cases were segregated by surgeon.

SETTING

Saint Louis University Hospital (SLU), San Antonio Military Medical Center (SAMMC), Madigan Army Medical Center (MAMC), and William Beaumont Army Medical Center (WBAMC).

PARTICIPANTS

All general surgery/trauma cases at participating hospitals between January 1, 2017 and January 1, 2019.

RESULTS

A total of 267 of 721 trauma cases performed by trauma/general surgeons at SAMMC were CCC-RCs, at SLU 213 of 342, MAMC, 5 of 13, and at WBAMC 1 of 33. While SAMMC had the most cases, SLU had the highest ratio of cases that were CCC-RC (p < 0.0001). The average number of CCC-RCs of the top 5 surgeons at each level 1 institutions were 15.7 cases/year (60.5%) at SLU and 10.3 cases/year (33.6%) at SAMMC (p < 0.0001).

CONCLUSIONS

The CCC-RC definition is easily used to distinguish the value and relevancy of trauma centers to general surgeon combat casualty care readiness. The volume and proportions of relevant trauma are significantly different between trauma centers. The military trauma designated hospitals are currently inadequate to support all general surgeon readiness needs. Embedding surgeons at centers with high volumes or relevant cases is the optimum solution.

Procedural Telementoring in Rural, Underdeveloped, and Austere Settings: Origins, Present Challenges, and Future Perspectives

Telemedicine is perhaps the most rapidly growing area in health care. Approximately 15 million Americans receive medical assistance remotely every year. Yet rural communities face significant challenges in securing subspecialist care. In the United States, 25% of the population resides in rural areas, where less than 15% of physicians work. Current surgery residency programs do not adequately prepare surgeons for rural practice. Telementoring, wherein a remote expert guides a less experienced caregiver, has been proposed to address this challenge. Nonetheless, existing mentoring technologies are not widely available to rural communities, due to a lack of infrastructure and mentor availability. For this reason, some clinicians prefer simpler and more reliable technologies. This article presents past and current telementoring systems, with a focus on rural settings, and proposes aset of requirements for such systems. We conclude with a perspective on the future of telementoring systems and the integration of artificial intelligence within those systems.

Enhanced Training Benefits of Video Recording Surgery With Automated Hand Motion Analysis

Background

Hand motion analysis by video recording during surgery has potential for evaluation of surgical performance. The aim was to identify how technical skill during open surgery can be measured unobtrusively by video recording during a surgical procedure. We hypothesized that procedural-step timing, hand movements, instrument use and Shannon entropy differ with expertise and training and are concordant with a performance-based validated individual procedure score.

Methods

Surgeon and non-surgeon participants with varying training and levels of expertise were video recorded performing axillary artery exposure and control (AA) on un-preserved cadavers. Color-coded gloves permitted motion-tracking and automated extraction of entropy data from recordings. Timing and instrument-use metrics were obtained through observational video reviews. Shannon entropy measured speed, acceleration and direction by computer-vision algorithms. Findings were compared with individual procedure score for AA performance

Results

Experts had lowest entropy values, idle time, active time and shorter time to divide pectoralis minor, using fewer instruments. Residents improved with training, without reaching expert levels, and showed deterioration 12–18 months later. Individual procedure scores mirrored these results. Non-surgeons differed substantially.

Conclusions

Hand motion entropy and timing metrics discriminate levels of surgical skill and training, and these findings are congruent with individual procedure score evaluations. These measures can be collected using consumer-level cameras and analyzed automatically with free software. Hand motion with video timing data may have widespread application to evaluate resident performance and can contribute to the range of evaluation and testing modalities available to educators, training course designers and surgical quality assurance programs.

Scoping Evidence Review on Training and Skills Assessment for Open Emergency Surgery

OBJECTIVE

Scope evidence on technical performance metrics for open emergency surgery. Identify surgical performance metrics and procedures used in trauma training courses.

DESIGN

Structured literature searches of electronic databases were conducted from January 2010 to December 2019 to identify systematic reviews of tools to measure surgical skills employed in vascular or trauma surgery evaluation and training.

SETTING AND PARTICIPANTS

Faculty of Shock Trauma Anesthesiology Research Center, University of Maryland School of Medicine, Uniformed Services University of Health Sciences, Bethesda, Maryland and Implementation Science, King's College, London.

RESULTS

The evidence from 21 systematic reviews including over 54,000 subjects enrolled into over 840 eligible studies, identified that the Objective Structured Assessment of Technical Skill was used for elective surgery not for emergency trauma and vascular control surgery procedures. The Individual Procedure Score (IPS), used to evaluate emergency trauma procedures performed before and after training, distinguished performance of residents from experts and practicing surgeons. IPS predicted surgeons who make critical errors and need remediation interventions. No metrics showed Kirkpatrick's Level 4 evidence of technical skills training benefit to emergency surgery outcomes.

CONCLUSIONS

Expert benchmarks, errors, complication rates, task completion time, task-specific checklists, global rating scales, Objective Structured Assessment of Technical Skills, and IPS were found to identify surgeons, at all levels of seniority, who are in need of remediation of technical skills for open surgical hemorrhage control. Large-scale, multicenter studies are needed to evaluate any benefit of trauma technical skills training on patient outcomes.

Maintaining vascular trauma proficiency for military non-vascular surgeons

Background

Vascular injuries in combat casualty patients are common and remain an ongoing concern. In civilian trauma centers, vascular surgeons are frequently available to treat vascular injuries. Within the military, vascular surgeons are not available at all locations where specialty expertise may be optimal. This study aims to determine if a visiting surgeon model, where a general surgeon can visit a civilian trauma center, would be practical in maintaining proficiency in vascular surgery.

Methods

All vascular trauma relevant cases done by any surgical service were identified during a 2-year period at Saint Louis University Hospital between October 1, 2016 and September 30, 2018. These included cases performed by trauma/general, thoracic, vascular, and orthopedic surgery. Predictions on the number of call days to experience an operative case were then calculated.

Results

A total of 316 vascular cases were performed during the time period. A surgeon on call for five 24-hour shifts would experience 2.1 urgent vascular cases with 95% certainty. To achieve five cases with 95% certainty, a surgeon would have to be on call for 34 24-hour shifts.

Discussion

A visiting surgeon model would be very difficult to maintain to acquire or maintain proficiency in vascular surgery. High-volume trauma centers, or centers with significant open vascular cases in addition to trauma, may have more reasonable time requirements, but would have to be evaluated using these methods.
