Maximizing the Calm before the Storm: Tiered Surgical Response Plan for Novel Coronavirus (COVID-19).

The novel coronavirus (COVID-19) was first diagnosed in Wuhan, China in December 2019 and has now spread throughout the world, being verified by the World Health Organization as a pandemic on March 11. This had led to the calling of a national emergency on March 13 in the US. Many hospitals, healthcare networks, and specifically, departments of surgery, are asking the same questions about how to cope and plan for surge capacity, personnel attrition, novel infrastructure utilization, and resource exhaustion. Herein, we present a tiered plan for surgical department planning based on incident command levels. This includes acute care surgeon deployment (given their critical care training and vertically integrated position in the hospital), recommended infrastructure and transfer utilization, triage principles, and faculty, resident, and advanced care practitioner deployment.

PATHway to success: Implementation of a multiprofessional acute trauma health care team decreased length of stay and cost in patients with neurological injury requiring tracheostomy.

BACKGROUND: The aim of this study was to determine whether the implementation of a dedicated multiprofessional acute trauma health care (mPATH) team would decrease length of stay without adversely impacting outcomes of patients with severe traumatic brain and spinal cord injuries. The mPATH team was comprised of a physical, occupational, speech, and respiratory therapist, nurse navigator, social worker, advanced care provider, and physician who performed rounds on the subset of trauma patients with these injuries from the intensive care unit to discharge. METHODS: Following the formation and implementation of the mPATH team at our Level I trauma center, a retrospective cohort study was performed comparing patients in the year immediately prior to the introduction of the mPATH team (n = 60) to those in the first full year following implementation (n = 70). Demographics were collected for both groups. Inclusion criteria were Glasgow Coma Scale score less than 8 on postinjury Day 2, all paraplegic and quadriplegic patients, and patients older than 55 years with central cord syndrome who underwent tracheostomy. The primary endpoint was length of stay; secondary endpoints were time to tracheostomy, days to evaluation by occupational, physical, and speech therapy, 30-day readmission, and 30-day mortality. RESULTS: The median time to evaluation by occupational, physical, and speech therapy was universally decreased. Injury Severity Score was 27 in both cohorts. Time to tracheostomy and length of stay were both decreased. Thirty-day readmission and mortality rates remained unchanged. A cost savings of US $11,238 per index hospitalization was observed. CONCLUSION: In the year following the initiation of the mPATH team, we observed earlier time to occupational, physical, and speech therapist evaluation, decreased length of stay, and cost savings in severe traumatic brain and spinal cord injury patients requiring tracheostomy compared with our historical control. These benefits were observed without adversely impacting 30-day readmission or mortality. LEVEL OF EVIDENCE: Therapeutic/care management, Level III.

Prospective study examining clinical outcomes associated with a negative pressure wound therapy system and Barker's vacuum packing technique.

BACKGROUND: The open abdomen has become a common procedure in the management of complex abdominal problems and has improved patient survival. The method of temporary abdominal closure (TAC) may play a role in patient outcome. METHODS: A prospective, observational, open-label study was performed to evaluate two TAC techniques in surgical and trauma patients requiring open abdomen management: Barker's vacuum-packing technique (BVPT) and the ABThera(TM) open abdomen negative pressure therapy system (NPWT). Study endpoints were days to and rate of 30-day primary fascial closure (PFC) and 30-day all-cause mortality. RESULTS: Altogether, 280 patients were enrolled from 20 study sites. Among them, 168 patients underwent at least 48 hours of consistent TAC therapy (111 NPWT, 57 BVPT). The two study groups were well matched demographically. Median days to PFC were 9 days for NPWT versus 12 days for BVPT (p = 0.12). The 30-day PFC rate was 69 % for NPWT and 51 % for BVPT (p = 0.03). The 30-day all-cause mortality was 14 % for NPWT and 30 % for BVPT (p = 0.01). Multivariate logistic regression analysis identified that patients treated with NPWT were significantly more likely to survive than the BVPT patients [odds ratio 3.17 (95 % confidence interval 1.22-8.26); p = 0.02] after controlling for age, severity of illness, and cumulative fluid administration. CONCLUSIONS: Active NPWT is associated with significantly higher 30-day PFC rates and lower 30-day all-cause mortality among patients who require an open abdomen for at least 48 h during treatment for critical illness.

Operative experience in the era of duty hour restrictions: is broad-based general surgery training coming to an end?

Since the institution of Accreditation Council for Graduate Medical Education (ACGME) resident work hour restrictions, conflicting evidence exists regarding the impact on resident case volume with most data from single-institution studies. We examined the effect of restrictions on national resident operative experience. After permission from the ACGME, we reviewed the publicly available national resident case log data (1999 through 2008) maintained on the ACGME web site (www.acgme.org), including total major cases with subanalysis of the ACGME-specified categories. The mean cases per resident were compared before (1999 to 2003) and after (2003 to 2008) restrictions. After the implementation of duty hour restrictions, the mean number of total cases per resident significantly decreased (949 +/- 18 vs 911 +/- 14, P = 0.004). Subanalysis showed a significant increase in alimentary tract (217 +/- 7 vs 229 +/- 3, P = 0.004), skin/soft tissue (31 +/- 3 vs 36 +/- 1, P = 0.01), and endocrine (26 +/- 2 vs 31 +/- 2, P = 0.006) cases. However, we observed a significant decrease in head and neck (21 +/- 0.3 vs 20 +/- 0.3, P = 0.01), vascular (164 +/- 29 vs 126 +/- 5, P = 0.01), pediatric (41 +/- 1 vs 37 +/- 2, P = 0.006), genitourinary (10 +/- 2 vs 7 +/- 1, P = 0.004), gynecologic surgery (5 +/- 1 vs 3 +/- 0.6, P = 0.002), plastics (16 +/- 0.3 vs 15 +/- 0.7, P = 0.03), and endoscopy (91 +/- 3 vs 82 +/- 2, P < 0.001) procedures. Analysis of the ACGME-compiled national data confirms that duty hour restrictions have significantly impacted resident operative experience. Importantly, experience in specialty areas, including vascular and endoscopy, appears to have been sacrificed for consolidation of resources into general surgery services as indicated by the increase in alimentary tract and endocrine cases. These findings raise the following question: Is the era of truly broad-based general surgery training coming to an end?

Trauma attending physician continuity: does it make a difference?

Continuity of care is important in achieving optimal outcomes in trauma patients, but the optimal length of the trauma attending (TA) rotation is unknown. We hypothesize that longer TA rotations provide greater continuity, and therefore improve outcomes. We did a retrospective comparison of trauma patient outcomes from two consecutive 6-month periods during which we transitioned from a 1-month TA rotation to a 1-week TA rotation. The Wilcoxon rank sum test, and the chi2 were used for statistical analysis. Over the 12-month study period 1924 patients were admitted to the Trauma Service. The two groups were similar with regard to age, gender, injury mechanism, Injury Severity Score and Glasgow Coma Scale scores, and Abbreviated Injury Scores for the chest, abdomen, and extremities. Although mortality, patient charges, and violations of the standard of care were similar between the two groups, overall morbidity was lower (18.6% vs. 23.2%), and hospital length of stay higher (9.07 days vs. 8.41 days) in the 1-week TA group compared with the 1-month TA group. A one-week TA rotation was associated with a longer hospital length of stay, but improved morbidity. Longer TA rotations do not necessarily provide improved continuity or improved outcomes.

Resident work hour restrictions impact chief resident operative experience.

Since the institution of the Accreditation Council for Graduate Medical Education resident work restrictions, much discussion has arisen regarding the potential effect on surgical resident training. We undertook this study to examine the effects on resident operative experience. We retrospectively analyzed chief residents' Accreditation Council for Graduate Medical Education case logs before (PRE) and after (POST) the 80-hour work restriction. Overall, 22 resident logs were evaluated, six PRE and 16 POST. Four case categories were examined: total major cases, total trauma operative cases, total chief cases, and total teaching assistant cases. Significance was defined as P < 0.05. Comparing the PRE and POST groups demonstrated a trend toward fewer total major cases (1061 vs 964, P = 0.38) and fewer total trauma operative cases (55 vs 47, P = 0.37). Teaching assistant cases increased from 67 to 91 but also failed to reach significance (P = 0.37). However, further comparison between the PRE and POST groups yielded a statistically significant decrease in the number of total chief cases (494 vs 333, P = 0.0092). The significant decrease in the number of total chief cases demonstrates that the work hour restriction most affected the chief year operative experience. Further evaluation of resident participation in nonoperative facets may reveal additional deficiencies of surgical training under work hour restrictions.

Factors influencing residency choice of general surgery applicants--how important is the availability of a skills curriculum?

OBJECTIVE: The objective of this study was to assess the factors that impact residency choice by general surgery applicants and the importance of the availability of skill curricula. METHODS: Fourth-year medical students (n = 104) interviewing for a general surgery position in an academic medical center voluntarily completed an anonymous survey detailing questions about the factors that influenced their choice of a residency program. Applicants were asked to rank in order of importance 14 factors potentially influencing their decision making and to address specifically the value of skills training. Data are reported as medians (range). RESULTS: The applicants' median age was 26 (range, 24-35) years; 44% were women, and the prior simulator exposure was 1 (range, 0-90) hour. The factors influencing the choice of residency in order of importance were the quality of life of current residents, the volume and variety of cases, and the quality of the curriculum (medians, 3-4), followed by the reputation of the institution and the program director, the location, and mentor advice (medians, 6-8); and the presence of expertise in areas of interest, the availability of a skills curriculum, the academic versus private designation, the efficiency of the hospital, and the size of residency (medians, 9-10). Women were more likely than men to rank lifestyle higher. Applicants' decision making was influenced positively in 92% by the presence of an organized skills curriculum. CONCLUSIONS: The main determinants of the applicants' choice of a general surgery program are the quality of life of the residents and the anticipated clinical experience and curriculum quality. The availability of organized skills curricula is low in the applicant priorities, but it does influence their decision-making process. These findings may help program directors to optimize their residency curriculum and interviewing process.

Audience response system technology improves accuracy and reliability of trauma outcome judgments.

BACKGROUND: Peer-review judgments are necessary for effective trauma performance improvement (PI), but may be influenced by peer pressure and the tendency to vote with the majority. Incorporation of Audience Response System (ARS) technology into trauma PI should result in improved outcome assessments. METHODS: We compared 30 months of nonanonymous trauma care judgments with 30 months of anonymous judgments obtained with the use of a keypad-based ARS. Statistical methods included the chi2 test and the Wilcoxon rank sum test. RESULTS: Use of the ARS resulted in a 28% reduction in deaths judged nonpreventable and a 24% reduction in trauma care judged to be appropriate (p < 0.0001). Unanimous outcome judgments were also significantly reduced (p < 0.0001). CONCLUSIONS: Outcome judgments obtained anonymously were significantly more divergent and less positive than those obtained nonanonymously. Anonymously derived outcome judgments may provide a better opportunity to identify adverse outcomes and thereby potentially improve trauma PI and trauma care.

Utility of neurosurgical consultation for mild traumatic brain injury.

Trauma patients presenting with a Glasgow Coma Scale (GCS) score of 14-15 are considered to have mild traumatic brain injury (TBI) with overall good neurologic outcomes. Current practice consists of initial stabilization, followed by a head CT, and neurosurgical consultation. Aside from serial neurologic examinations, patients with a GCS of 15 rarely require neurosurgical intervention. In this study, we examined the added value of neurosurgical consultation in the care of patients after TBI with a GCS of 15. We retrospectively reviewed the medical records of patients presenting after blunt trauma with an abnormal head CT and GCS of 15 between January 2004 and January 2005. Patients with a normal head CT and <48 hours hospital stay were excluded. Data included demographics, mechanisms of injury, Injury Severity Score, the radiologists' dictated interpretations of the head CT, and neurosurgical interventions. Fifty-six patients met the inclusion criteria. The mean age was 41+/-2.3 years, and the mean Injury Severity Scores was 10.2 +/-0.6. Mechanisms of injury included 64 per cent motor vehicle crash, 16 per cent motorcycle crash, 13 per cent fall, and 7 per cent all-terrain vehicle crash. The initial CT scans showed 43 per cent parenchymal contusions, 38 per cent subarachnoid hemorrhage, 14 per cent subdural hematomas, and 5 per cent epidural hematomas. All patients received a routine follow-up head CT, and 16 per cent showed changes (five improved and four were worse compared with initial CT scans). None of these patients received a neurosurgical intervention, and two were transferred to a rehabilitation service. In this era of limited resources, trauma patients who present with a GCS score of 15 after mild TBI can be safely managed without neurosurgical consultation, even in the presence of an abnormal head CT scan.

The role of transesophageal echocardiography in optimizing resuscitation in acutely injured patients.

BACKGROUND: The goal of resuscitation is to correct the mismatch between oxygen delivery and that of cellular demands. The pulmonary artery catheter (PAC) is frequently used to gauge the adequacy of resuscitation and guide therapy based on ventricular filling pressures. Transesophageal echocardiography (TEE) has emerged as a potential tool in assessing adequacy of acute hemodynamic resuscitation. The purpose of this study was to evaluate the role of TEE in assessing preload during ongoing volume resuscitation in trauma patients. METHODS: A retrospective review was conducted of acutely injured patients undergoing TEE during resuscitation from hemorrhagic shock from January 2002 to 2004 at a Level I trauma center. The indication for TEE was persistent hemodynamic instability in the absence of ongoing surgical hemorrhage. Variables included hemodynamic and PAC parameters, pre-TEE resuscitation volume, and vasopressor requirements. The impact of TEE findings on therapeutic decisions was evaluated. RESULTS: Twenty-five patients underwent TEE, 18 (72%) had an indwelling PAC with a mean pulmonary artery occlusion pressure of 19.3 mm Hg (range, 12-29 mm Hg) and mean cardiac index of 2.9 L/min/m2 (range, 1.6-4.6 L/min/m2). Twelve patients (48%) were receiving inotropes and/or vasopressors for hypotension at the time of TEE. Resuscitation volume within 6 hours before TEE included a mean of 6.5 L of crystalloid and 12.2 units of blood products (packed red blood cells, fresh frozen plasma, and platelets). TEE revealed left ventricular hypovolemia in 13 patients (52%) and altered therapy in 16 patients (64%), including additional volume (n = 13), addition of an inotrope (n = 4), and addition of a vasodilator (n = 1) in one patient with ventricular overdistention. Comparison of the abnormal and normal TEE groups revealed that only cardiac index was significantly different (2.6 L/min/m2 in the abnormal group vs. 3.9 L/min/m2 in the normal group; p = 0.005). Significant mitral valve regurgitation leading to valve replacement was identified in one patient. No clinically relevant pericardial effusion was identified. CONCLUSION: TEE altered resuscitation management in almost two thirds of patients. Many patients with "acceptable" pulmonary artery occlusion pressure parameters may in fact have inadequate left ventricular filling. In addition, TEE offers the advantage of direct assessment of cardiac valve competency, myocardial wall contractility, and pericardial fluid.

Gender-related outcomes in trauma.

BACKGROUND: Recent data suggest that sex hormones may play a role in regulating posttraumatic immunosuppression, leading to gender-based differences in outcome after injuries. This study examined gender-related outcomes in trauma patients. METHODS: We conducted a retrospective review of trauma registry data from our Level I trauma center over a 4-year period. Patients > 15 years of age, with Injury Severity Scores > 15, who survived and received mechanical ventilation for > 48 hours were included. Patients were divided into two groups on the basis of age (15-45 years and > 45 years) and the groups were further stratified by gender. Groups were matched by Injury Severity Scores, Glasgow Coma Scale score, Abbreviated Injury Score for the head, and transfusion requirement. Gender-based outcomes consisted of ventilator days, intensive care unit length of stay (LOS), hospital LOS, pneumonia, and death. RESULTS: Data were reported as mean +/- SD. There were 612 patients. In the younger age group, male patients had a higher incidence of multiple organ failure (10.5% vs. 1.5%), longer intensive care unit (13.5 +/- 9.2 days vs. 9.2 +/- 7.2 days) and hospital LOS (30.2 +/- 37.7 days vs. 18.9 +/- 13.0 days), and higher mortality (13.4% vs. 6.8%) compared with female patients (p < 0.05 for all). These differences did not exist in the older age group. The incidence of pneumonia did not differ by gender. Age > 45 years was associated with higher mortality (odds ratio, 2.0; 95% confidence interval, 1.1-3.5). CONCLUSION: Although the incidence of pneumonia was not influenced by gender, female trauma patients had better outcomes than male patients in the younger age group. Outcome in the older age group was not gender-related. Our data support a gender-based difference in outcome after traumatic injuries in younger patients.
