Epidemiology, Management, and Outcomes of Accidental Hypothermia: A Multicenter Study of Regional Care.

BACKGROUND: Hypothermia is an uncommon, potentially life-threatening condition. We hypothesized (1) advanced rewarming techniques were more frequent with increased hypothermia severity, (2) active rewarming is increasingly performed with smaller intravascular catheters and decreased cardiopulmonary bypass, and (3) mortality was associated with age, hypothermia severity, and type. METHODS: Trauma patients with temperatures <35°C at 4 ACS-verified trauma centers in Wisconsin and Minnesota from 2006 to 2016 were reviewed. Statistical analysis included chi-square and Fisher's exact tests. A P value < .05 was considered significant. RESULTS: 337 patients met inclusion criteria; primary hypothermia was identified in 127 (38%), secondary in 113 (34%), and mixed primary/secondary in 96 (28%) patients. Hypothermia was mild in 69%, moderate in 26%, and severe in 5% of patients. Intravascular rewarming catheter was the most frequent advanced modality (2%), used increasingly since 2014. Advanced techniques were used for primary (12%) vs. secondary (0%) and mixed (5%) (P = .0002); overall use increased with hypothermia severity but varied by institution. Dysrhythmia, acute kidney injury, and frostbite risk worsened with hypothermia severity (P < .0001, P = .031, and P < .0001, respectively). Mortality was greatest in patients with mixed hypothermia (39%, P = .0002) and age >65 years (33%, P = .03). Thirty-day mortality rates were similar among severe, moderate, and mild hypothermia (P = .44). CONCLUSION: Advanced rewarming techniques were used more frequently in severe and primary hypothermia but varied among institutions. Advanced rewarming was less common in mixed hypothermia; mortality was highest in this subgroup. Reliance on smaller intravascular catheters for advanced rewarming increased over time. Given inconsistencies in management, implementation of guidelines for hypothermia management appears necessary.

The role of palliative care in acute trauma: When is it appropriate?

INTRODUCTION: We hypothesized that trauma providers are reticent to consider palliative measures in acute trauma care. METHODS: An electronic survey based on four patient scenarios with identical vital signs and serious blunt injuries, but differing ages and frailty scores was sent to WTA and EAST members. RESULTS: 509 (24%) providers completed the survey. Providers supported early transition to comfort care in 85% old-frail, 53% old-fit, 77% young-frail, and 30% young-fit patients. Providers were more likely to transition frail vs. fit patients with (OR = 4.8 [3.8-6.3], p < 0.001) or without (OR = 16.7 [12.5-25.0], p < 0.001) an advanced directive (AD) and more likely to transition old vs. young patients with (OR = 2.0 [1.6-2.6], p < 0.001) or without (OR = 4.2 [2.8-5.0], p < 0.001) an AD. CONCLUSIONS: In specific clinical situations, there was wide acceptance among trauma providers for the early institution of palliative measures. Provider decision-making was primarily based on patient frailty and age. ADs were helpful for fit or young patients. Provider demographics did not impact decision-making.

Impact of Advance Directives on Outcomes and Charges in Elderly Trauma Patients.

Background: As the number of geriatric trauma patients rises, end-of-life planning is of increased importance. A community-wide initiative to increase advance care planning was undertaken in the 1990s, resulting in a high rate (85%) of completed advance directives (ADs). Objectives: To assess the impact of ADs on quality measures of care and outcomes for elderly trauma patients. To determine if the historically high rate of completed ADs in the community applied to the trauma patient population. Design: A single trauma center's registry was retrospectively reviewed. Patients with versus without an AD were compared. A case-control analysis was completed. Statistical analysis included chi-square test, Wilcoxon rank sum, and multivariate linear regression modeling. Setting: American College of Surgeons-verified level II trauma center with a 325-bed teaching hospital. Subjects: Patients ≥55 years admitted as level I or II activations from January 2007 through April 2017. Measurements: Hospital and intensive care unit (ICU) length of stay (LOS), ventilator days, and 30-day mortality. Results: Nine hundred thirty-six patients were identified; 173 (18%) had an AD and 763 (82%) did not. ADs were more common among older, female patients. The majority of patients with ADs lived within the medical center's service area (99% vs. 1%) and had a primary care provider within the health care system (72% vs. 28%). Although 30-day mortality was higher in patients with ADs versus without (21% vs. 15%; p = 0.03), this difference was not significant on case-control analysis (20% vs. 15%, p = 0.31). No difference was identified in LOS, ICU days, ventilator days, or charges. Conclusions: Presence of an AD was not associated with any difference in 30-day mortality, LOS, or hospital charges. More widespread efforts at AD education and documentation are necessary, particularly in the setting of trauma.

Enhancing Confidence in Graduating General Surgery Residents: Establishing a Chief Surgery Resident Service at an Independent Academic Medical Center.

OBJECTIVE: Providing opportunities for autonomy to enhance the development of independence and confidence during surgery residency remains among the greatest challenges of the current training paradigm. The objective of this study was to evaluate the implementation and outcomes of a chief resident service (CRS). DESIGN: A CRS was designed with operative, call and office responsibilities. Supervision and evaluation were consistent with institutional guidelines. CRS operative logs from 2011 to 2014 were compared with logs from the participants' first year in practice. Select procedures were compared and evaluations were reviewed. Residency graduates' satisfaction with the CRS was evaluated. SETTING: Independent academic medical center. PARTICIPANTS: Nine general surgery residency graduates with one complete year in practice. RESULTS: Nine residents completed CRS rotations and submitted case logs. Median total case volume was 1101 (994-1311) during the 5-year residency, 92 (20-149) during CRS and 299 (99-784) during the first year in practice. Median case volumes for selected procedures for the entire 5-year residency, CRS, and first year of practice were: 93 (66-97), 7 (3-16), and 9 (1-26) laparoscopic appendectomies; 146 (120-157), 24 (3-32), and 34 (15-112) laparoscopic cholecystectomies; 81 (51-94), 1 (1-4), and 3 (0-8) ileocolectomies; 57 (35-86), 4 (0-9), and 8 (2-34) ventral/incisional hernia repairs; 102 (87-137), 12 (3-16), and 13 (3-86) inguinal hernia repairs. Graduates reported that the CRS experience was very beneficial to their current practice. Annual program reviews emphasized the CRS as a major strength of our residency. CONCLUSIONS: Creation of a CRS to increase resident autonomy and provide continuity of patient care with appropriate faculty supervision was successful. Case mix and volumes provided an opportunity for independent operative and clinical experience during residency which realistically paralleled graduates' first year of practice.

Contemporary management of subclavian and axillary artery injuries-A Western Trauma Association multicenter review.

BACKGROUND: Subclavian and axillary artery injuries are uncommon. In addition to many open vascular repairs, endovascular techniques are used for definitive repair or vascular control of these anatomically challenging injuries. The aim of this study was to determine the relative roles of endovascular and open techniques in the management of subclavian and axillary artery injuries comparing hospital outcomes, and long-term limb viability. METHODS: A multicenter, retrospective review of patients with subclavian or axillary artery injuries from January 1, 2004, to December 31, 2014, was completed at 11 participating Western Trauma Association institutions. Statistical analysis included χ, t-tests, and Cochran-Armitage trend tests. A p value less than 0.05 was significant. RESULTS: Two hundred twenty-three patients were included; mean age was 36 years, 84% were men. An increase in computed tomography angiography and decrease in conventional angiography was observed over time (p = 0.018). There were 120 subclavian and 119 axillary artery injuries. Procedure type was associated with injury grade (p < 0.001). Open operations were performed in 135 (61%) patients, including 93% of greater than 50% circumference lacerations and 83% of vessel transections. Endovascular repairs were performed in 38 (17%) patients; most frequently for pseudoaneurysms. Fourteen (6%) patients underwent a hybrid procedure. Use of endovascular versus open procedures did not increase over the duration of the study (p = 0.248). In-hospital mortality rate was 10%. Graft or stent thrombosis occurred in 7% and graft or stent infection occurred in 3% of patients. Mean follow-up was 1.6 ± 2.4 years (n = 150). Limb salvage was achieved in 216 (97%) patients. CONCLUSION: The management of subclavian and axillary artery injuries still requires a wide variety of open exposures and procedures, especially for the control of active hemorrhage from more than 50% vessel lacerations and transections. Endovascular repairs were used most often for pseudoaneurysms. Low early complication rates and limb salvage rates of 97% were observed after open and endovascular repairs. LEVEL OF EVIDENCE: Prognostic/epidemiologic, level IV.

Natural history of splenic vascular abnormalities after blunt injury: A Western Trauma Association multicenter trial.

BACKGROUND: Following blunt splenic injury, there is conflicting evidence regarding the natural history and appropriate management of patients with vascular injuries of the spleen such as pseudoaneurysms or blushes. The purpose of this study was to describe the current management and outcomes of patients with pseudoaneurysm or blush. METHODS: Data were collected on adult (aged ≥18 years) patients with blunt splenic injury and a splenic vascular injury from 17 trauma centers. Demographic, physiologic, radiographic, and injury characteristics were gathered. Management and outcomes were collected. Univariate and multivariable analyses were used to determine factors associated with splenectomy. RESULTS: Two hundred patients with a vascular abnormality on computed tomography scan were enrolled. Of those, 14.5% were managed with early splenectomy. Of the remaining patients, 59% underwent angiography and embolization (ANGIO), and 26.5% were observed. Of those who underwent ANGIO, 5.9% had a repeat ANGIO, and 6.8% had splenectomy. Of those observed, 9.4% had a delayed ANGIO, and 7.6% underwent splenectomy. There were no statistically significant differences between those observed and those who underwent ANGIO. There were 111 computed tomography scans with splenic vascular injuries available for review by an expert trauma radiologist. The concordance between the original classification of the type of vascular abnormality and the expert radiologist's interpretation was 56.3%. Based on expert review, the presence of an actively bleeding vascular injury was associated with a 40.9% risk of splenectomy. This was significantly higher than those with a nonbleeding vascular injury. CONCLUSIONS: In this series, the vast majority of patients are managed with ANGIO and usually embolization, whereas splenectomy remains a rare event. However, patients with a bleeding vascular injury of the spleen are at high risk of nonoperative failure, no matter the strategy used for management. This group may warrant closer observation or an alternative management strategy. LEVEL OF EVIDENCE: Prognostic study, level III.

Duplex Ultrasound Surveillance After Uncomplicated Endovascular Abdominal Aortic Aneurysm Repair.

OBJECTIVES: Health-care costs and risks of radiation and intravenous contrast exposure challenge computed tomography angiography (CTA) as the standard surveillance method after endovascular abdominal aortic aneurysm repair (EVAR). We reviewed our experience using Duplex ultrasound scan (DUS) as an initial and subsequent surveillance technique after uncomplicated EVAR. METHODS: The medical records of patients who underwent EVAR from 2004 to 2014 with at least 1 postoperative imaging study were retrospectively reviewed. Duplex ultrasound scan was the primary modality, with CTA reserved for patients with suspicious findings. RESULTS: Mean follow-up was 3.2 years for 266 patients. Fifty-seven endoleaks (7 type I, 50 type II) were detected in 51 patients (19%). Nineteen (33%) endoleaks were identified and monitored by DUS alone. Nine (16%) endoleaks were identified on CTA without prior DUS. Twenty-two (39%) endoleaks were identified on DUS and confirmed by CTA; 6 of these patients had a secondary intervention. When compared to subsequent CTA, there were 7 discordant results: 4 false-negative and 3 false-positive endoleaks on DUS. Two of these patients with discordant results required intervention. Follow-up CTA was not obtained for the other 2 patients due to severe comorbidities including renal disease. One of these patients eventually developed abdominal aortic aneurysm rupture and death. Among 88 patients with both DUS and CTA, positive predictive value and negative predictive value for DUS were 0.88 and 0.94, respectively. Sac size on DUS compared to CTA resulted in an interclass correlation coefficient of r = .84. CONCLUSIONS: In our experience, DUS was safe and effective for initial and follow-up surveillance after uncomplicated EVAR.

Rural General Surgery: A 38-Year Experience with a Regional Network Established by an Integrated Health System in the Midwestern United States.

BACKGROUND: General surgeon (GS) workforce shortages are predicted to worsen, particularly in rural areas. We report on a sustainable model for delivery of GS services within a large rural region that includes an integrated health system. STUDY DESIGN: We conducted a longitudinal study of a rural GS network from 1978 to 2016. Employment data and rural GS survey results were reviewed to document methods of recruitment, retention, and case-volume development. RESULTS: During the 38-year study period, 19 rural GSs were employed by the health system. There were 3 practice acquisitions and 16 new hires. The rural GS network grew from 1 in 1978 to 10 in 2016. In 1996, the network consisted of 6 rural GSs at 6 different critical access hospitals (CAHs). Currently, 9 rural GSs practice at 1 of 4 CAHs. They provide outpatient general surgery and endoscopy at an additional 6 CAHs and cesarean section coverage at 4 CAHs. Four (21%) rural GSs have retired, 10 (53%) continue to practice in the network, and only 5 (26%) left before retirement. Six rural GSs have practiced in one location for more than 20 years. CONCLUSIONS: Successful recruitment of rural GSs depends on competitive salary, reasonable call and leave schedules, administrative support, and adequate case variety and volume. Case volume is enhanced by cooperative relationships with CAHs, health system assistance in performing appropriate procedures locally, co-management of complex cases, and development of outreach surgical locations. In addition to the recruitment principles mentioned, rural GS retention is optimized by connectivity with the main campus medical center.

Transition from Training to Surgical Practice.

Surgical training graduates require a period of adjustment as they transform from trainees to experienced surgeons. Making a smooth transition is important for patient safety and new surgeon success. A subset of current graduates does not feel confident to enter directly into practice. Residency design with curriculum refocus, credentialing to encourage graded responsibility, and increased operative exposure is necessary. Onboarding programs should include formal mentoring, career counseling, proctoring by senior surgeons, and objective review of outcomes. The ACS developed a one-year TTP program to provide independent decision-making, operative autonomy, mentoring by senior surgeons, and practice management experience.

Factors influencing the decision of surgery residency graduates to pursue general surgery practice versus fellowship.

OBJECTIVES: Surgery residency serves 2 purposes-prepare graduates for general surgery (GS) practice or postresidency surgical fellowship, leading to specialty surgical practice (SS). This study was undertaken to elucidate factors influencing career choice for these 2 groups. METHODS: All US allopathic surgery residency graduates from 2009 to 2013 (n = 5512) were surveyed by the American Board of Surgery regarding confidence, autonomy, and reasons for career selection between GS and SS. Surveys were distributed by mail in November 2013, with follow-up mailings to initial nonrespondents. RESULTS: Sixty-one percent (3354) of graduates completed the survey; 26% pursued GS, and 74% SS. GS expressed greater levels of confidence than SS across the common surgical procedures queried. Confidence increased with each year after completion of residency for GS but not SS. The decision to pursue GS or SS was made during residency by 77% and 74%, respectively. Fifty-seven percent of those who chose GS indicated that a GS mentor significantly influenced their decision. GS rated procedural variety, opportunity for practice autonomy, choice of practice location, and influence of a mentor as reasons to pursue GS practice. SS listed control over scope of practice, prestige, salary, and specialty interest as reasons to pursue SF. Both groups expressed a high degree of satisfaction with their career choice (GS, 94%; SS, 90%). CONCLUSIONS: Most graduates who pursue GS practice are confident and content. The decision to pursue GS is strongly influenced by a GS mentor. Lack of confidence may be a more significant factor for choosing SS. These findings suggest opportunities for improvements in confidence and mentorship during residency.

Resident Preparation for Careers in General Surgery: A Survey of Program Directors.

OBJECTIVE: The number of general surgery (GS) residency graduates who choose GS practice has diminished as the popularity of postresidency fellowships has dramatically increased over the past several decades. This study was designed to document current methods of GS preparation during surgery residency and to determine characteristics of programs that produce more graduates who pursue GS practice. DESIGN: An email survey was sent by the American Board of Surgery General Surgery Advisory Committee to program directors of all GS residencies. Program demographic information was procured from the American Board of Surgery database and linked to survey results. Multiple regression was used to predict postresidency choices of graduates. SETTING: Totally, 252 US allopathic surgical residencies. PARTICIPANTS: Totally, 171 residency program directors (68% response rate). RESULTS: The proportion of programs using an emergency/acute care surgery rotation at the main teaching hospital to teach GS increased from 63% in 2003 to 83% in 2014. An autonomous GS outpatient experience was offered in 38% of programs. Practice management curricula were offered in 28% of programs. Institutions with fewer postresidency fellowships (p < 0.003) and fewer surgical specialty residencies (p < 0.036) had a greater percentage of graduates who pursued GS practice. The addition of each fellowship at an institution was associated with a 2% decrease in the number of graduates pursuing GS practice. Residency size was not associated with predilection for fellowship selection and there was no difference between university and independent residencies vis-a-vis the proportion selecting fellowship vs GS practice. CONCLUSIONS: Practice management principles and autonomous GS outpatient clinic experiences are offered in a minority of programs. Graduates of programs in institutions with fewer surgery fellowships and residencies are more likely to pursue GS practice. Increased number of postresidency fellowships and specialty residencies may be associated with fewer GS rotations and fewer GS mentors. Further study of these relationships seems warranted.

Practice administration training needs of recent general surgery graduates.

INTRODUCTION: Practice administration education and experience during surgery residency are variable among residency programs. To better understand these issues, a survey of recent General Surgery residency (GS) graduates was compared with the results from a survey of GS program directors (PD). METHODS: All GS graduates completing residency from 2009 to 2013 (n = 5,512) were surveyed to assess opinions regarding the desire for more instruction during residency in practice administration. General surgeons were defined as those not pursuing fellowship training; specialist surgeons (SS) completed additional training after their GS residency. Separately, all GS residency PDs were surveyed regarding practice administration education in their programs. RESULTS: A total of 3,354 responded to the GS graduate survey (response rate = 61%). GS comprised 26% of the respondents. The vast majority of all respondents desired more training in practice administration. There were no significant differences in the degree to which instruction was desired among GS, SS, residency program type, or current practice setting. The GS PD response rate was 68% (171/252 programs). Only 28% of programs included practice administration in the residency curriculum. CONCLUSION: Practice administration education is highly desired by GS and SS graduates. Our findings indicate a clear need for a curriculum in practice administration during residency.

A novel trauma leadership model reflective of changing times.

As a result of generational changes in the health care workforce, we sought to evaluate our current Trauma Medical Director Leadership model. We assessed the responsibilities, accountability, time requirements, cost, and provider satisfaction with the current leadership model. Three new providers who had recently completed fellowship training were hired, each with unique professional desires, skill sets, and experience. Our goal was to establish a comprehensive, cost-effective, accountable leadership model that enabled provider satisfaction and equalized leadership responsibilities. A 3-pronged team model was established with a Medical Director title and responsibilities rotating per the American College of Surgeons verification cycle to develop leadership skills and lessen hierarchical differences.

Efficiencies gained by using electronic medical record and reports in trauma documentation.

Despite successful implementation of an electronic medical record (EMR) by many health care organizations, information regarding EMR for trauma resuscitation is limited, and few have created reports that facilitate trauma registry data abstraction, performance improvement reviews, and provider care requirements. In October 2010, our organization implemented an EMR for trauma resuscitations. A collaborative committee was formed to standardize data elements. Documentation compliance was monitored pre- and post-EMR implementation. Median monthly documentation completion improved from 82% to a sustained median score of 96.5% for the past 603 activations. Documentation compliance enabled the development of succinct reports that facilitate our internal needs and supported our trauma center reverification site visit.

Evolution in the management of traumatic diaphragmatic injuries: a multicenter review.

BACKGROUND: Traumatic diaphragmatic injury (TDI) is uncommon and has historically been identified by chest x-ray and repaired by laparotomy with nonabsorbable suture. Blunt TDI was more frequently (90%) detected on the left. With advances in imaging and operative techniques, our objective was to evaluate evolution in incidence, location, and management of TDI. METHODS: The medical records of patients admitted to three Wisconsin regional trauma centers with TDI from 1996 to 2011 were reviewed. Patients were stratified into blunt and penetrating injury and early (1996-2003) and recent (2004-2011) periods. p < 0.05 was significant. RESULTS: A total of 454 patients was included, 87% were men. Median Injury Severity Score (ISS) was 22 and 19 in the early and recent periods, respectively. Diagnostic modality for TDI did not change over time when comparing chest x-ray, computed tomography, or intraoperative diagnosis for blunt (p = 0.214) or penetrating (p = 0.119) TDI. More right-sided penetrating TDI were identified in the recent versus early group (49% vs. 27%). Perihiatal injury was rare (2%). Minimally invasive repairs increased in the recent versus early group of penetrating TDI (5.8% vs. 0.9%, p = 0.040). Complex repairs (mesh, transposition) were required in only three patients. In-hospital mortality was 15% and 4% for blunt and penetrating TDIs, respectively (p < 0.001). CONCLUSION: A large increase in the frequency of both blunt and penetrating TDIs in our region was documented. While no difference was observed regarding diagnosis of blunt TDI during the two study periods, our data show a change from historical reports; more injuries were detected by computed tomography. An increase in right-sided penetrating TDI was also observed. A small but previously unreported incidence of perihiatal/pericardial injury occurred with both blunt and penetrating TDIs. While the majority of injuries were repaired with laparotomy, minimally invasive repairs were used more frequently in the recent period. LEVEL OF EVIDENCE: Epidemiologic study, level III. Therapeutic study, level IV.
