Multiyear experience with mobile online platform for documentation of acute care surgery fellows supervision.

BACKGROUND: There is currently no standard for documenting supervision of acute care surgery (ACS) fellows. To accomplish this goal, we developed a web-based survey that is accessible via mobile platform. We hypothesize that our mobile access survey is an effective, reproducible tool for assessing fellow clinical performance. METHODS: A retrospective review from 2016 to 2022 of all data captured in an encrypted database on all ACS fellows at our institution was performed. Supervision was defined as: Type 1 direct face-to-face, Type 2a immediately available in-house, Type 2b available after notification via phone with remote electronic medical record access, and Type 3 retrospective review. Data were collected by supervising faculty using a web-based clinical performance survey created by fellowship program leadership. Survey data collected included clinical summary, trainee, proctoring faculty, clinical service, operative/nonoperative, supervision type, Zwisch autonomy scale, time to input data, and graduate medical education milestone performance. Data were analyzed using descriptive statistics. RESULTS: A total of 883 proctoring events were identified, including the majority as Type 1 (97.4%). Trauma comprised 64% of evaluations. Fifty-two percent of the proctoring events were surgical cases. Complexity was graded as average (77%), hardest (16%), basic (7%). Guidance included supervision only, 491 of 666 (74%), with 26% requiring faculty intervention. Fellow performance was graded as average (66%), above average (31%), and below average/critical deficiency (3%). Graduate medical education performance was available for 247 of 883 interactions identifying 31 events with potential for improvement. Average evaluation completion time: 2 minutes (n = 134). CONCLUSION: A mobile web-based survey is a convenient and reliable tool for documenting ACS fellow clinical activity and was effectively used by all ACS faculty to record supervision. A combination of clinical and objective data is useful to determine ACS fellows' performance and to provide targeted education and remediation. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Assessment of safety and effectiveness of non-neurosurgical management for minimal traumatic brain injury (TBI).

BACKGROUND: Patients with mild traumatic brain injury (TBI) and intracranial hemorrhage often receive neurosurgical consultation. However, only a small proportion of patients require intervention. Our hypothesis is that low-risk minimal TBI patients managed without immediate neurosurgical consultation will have a reasonable safety and effectiveness outcome profile. METHODS: A non-neurosurgical management protocol for adult minimal TBI was implemented at a level I trauma center as an interdisciplinary quality-improvement initiative in November 2018. Minimal TBI was defined as Glasgow Coma Scale (GCS) of 15 secondary to blunt mechanism, without anticoagulant or antiplatelet therapy, and isolated pneumocephalus and/or traumatic subarachnoid hemorrhage on head CT imaging. Safety was assessed by in-hospital mortality, neurosurgical interventions, and ED revisits within two weeks of discharge. Effectiveness was assessed by neurosurgical consult rate and length of stay. Outcomes were compared 8-months pre- and post-protocol implementation. RESULTS: A total of 97 patients were included, of which 49 were pre-protocol and 48 were post-protocol There was no difference in rates of in-hospital mortality [0 (0%) vs 0 (0%)], neurosurgical procedure [1 (2.1%) vs 0 (0%)], operations [0 (0%) vs 0 (0%)], and ED revisits [1 (2.0%) vs 2 (4.2%), p = 0.985] between the periods. There was a significant reduction in neurosurgical consults post-protocol implementation (92% vs 29%, p<0.001). CONCLUSION: A protocol for minimal TBI patients effectively reduced neurosurgical consultation without changes in safety profile. Such an interdisciplinary management protocol for low-risk neurotrauma can effectively utilize the neurosurgery consult services by stratifying neurologically stable TBI patient.

The choices we make: Ethical challenges in trauma surgery.

BACKGROUND: Ethical issues in trauma surgery are commonplace but scarcely studied. We aim to characterize the ethical dilemmas trauma surgeons encounter in clinical practice and describe perceptions about the ability to manage these dilemmas and strategies they use to address them. METHODS: Members of a U.S. trauma society were electronically surveyed on handling ethically challenging scenarios. The survey instrument was developed using published ethics literature and iterative cognitive interviews. Domains included perceived frequency of encountering and self-efficacy of managing ethical situations in trauma surgery. Common situations were defined as those encountered monthly or weekly. Ethical problems were categorized within 7 larger categories: general ethics, autonomy, communication, justice, end-of-life, conflict, and other. Descriptive analyses were performed; group comparisons were analyzed using analysis of variance. RESULTS: Of 1,748 surveyed, 548 responded (30.6%) and 154 (28%) were female. Most were White, under 55 years age, had completed fellowship training, and were practicing at a level I or II trauma center. The most encountered ethical categories were generic ethics and communication (79%). Issues involving conflict were least frequent (21%). Respondents felt most uncomfortable with autonomy topics. Respondents with high self-efficacy in handling ethical situations were older, in practice ≥15 years, served on an ethics committee, and/or frequently experienced ethical challenges. CONCLUSION: Most trauma surgeons regularly encounter ethical challenges, especially those related to communication. Trauma surgeons encounter ethical issues involving conflict least often, and lowest self-efficacy scores with issues involving autonomy. Experienced trauma surgeons reported higher self-efficacy scores in managing ethical issues. Future work should examine how self-efficacy translates to observed behavior, and how trauma surgeons build and enhance their ethical skillsets in the care of the injured patient.

Limitations of Available Blood Products for Massive Transfusion During Mass Casualty Events at US Level 1 Trauma Centers.

INTRODUCTION: Exsanguination remains a leading cause of preventable death in traumatically injured patients. To better treat hemorrhagic shock, hospitals have adopted massive transfusion protocols (MTPs) which accelerate the delivery of blood products to patients. There has been an increase in mass casualty events (MCE) worldwide over the past two decades. These events can overwhelm a responding hospital's supply of blood products. Using a computerized model, this study investigated the ability of US trauma centers (TCs) to meet the blood product requirements of MCEs. METHODS: Cross-sectional survey data of on-hand blood products were collected from 16 US level-1 TCs. A discrete event simulation model of a TC was developed based on historic data of blood product consumption during MCEs. Each hospital's blood bank was evaluated across increasingly more demanding MCEs using modern MTPs to guide resuscitation efforts in massive transfusion (MT) patients. RESULTS: A total of 9,000 simulations were performed on each TC's data. Under the least demanding MCE scenario, the median size MCE in which TCs failed to adequately meet blood product demand was 50 patients (IQR 20-90), considering platelets. Ten TCs exhaust their supply of platelets prior to red blood cells (RBCs) or plasma. Disregarding platelets, five TCs exhausted their supply of O- packed RBCs, six exhausted their AB plasma supply, and five had a mixed exhaustion picture. CONCLUSION: Assuming a TC's ability to treat patients is limited only by their supply of blood products, US level-1 TCs lack the on-hand blood products required to adequately treat patients following a MCE. Use of non-traditional blood products, which have a longer shelf life, may allow TCs to better meet the blood product requirement needs of patients following larger MCEs.

The Silent Majority of Emergency General Surgery: An Assessment of Consult and Operative Volumes.

BACKGROUND: Defining the work performed by emergency general surgery (EGS) surgeons has relied on quantifying surgical interventions, failing to include nonsurgical management performed. The purpose of this study was to identify the extent of operative and nonoperative patient management provided by an EGS service line in response to consults from other hospital providers. METHODS: This is a retrospective descriptive study of all adult patients with an EGS consult request placed from July 1, 2014 to June 30, 2016 at a 1000-bed tertiary referral center. Consult requests were classified by suspected diagnosis and linked to patient demographic and clinical information. Operative and nonoperative cases were compared. RESULTS: About 4998 EGS consults were requested during the 2-y period, of which 69.6% were placed on the first day of the patient encounter. Disposition outcomes after consultation included admission to the EGS service (27.6%) and discharge from the emergency department (25.3%). Small bowel obstruction, appendicitis, and cholecystitis decisively comprised the top three diagnoses for overall consults and those requiring admission to the EGS service. For every consult requiring an operation (n = 1400), 2.6 consults were managed without an operation (n = 3598). CONCLUSIONS: EGS surgeons are asked to evaluate and manage a variety of potentially surgical diagnoses. As most consults do not require surgical intervention, operative volume is a poor surrogate for quantifying EGS productivity. The role of this service is vital to patient triage and disposition, particularly in the emergency department setting. Institutions should consider the volume of their nonoperative consultations when evaluating EGS service line workload and in guiding staffing needs.

Artificial intelligence in trauma systems.

Local trauma care and regional trauma systems are data-rich environments that are amenable to machine learning, artificial intelligence, and big-data analysis mechanisms to improve timely access to care, to measure outcomes, and to improve quality of care. Pilot work has been done to demonstrate that these methods are useful to predict patient flow at individual centers, so that staffing models can be adapted to match workflow. Artificial intelligence has also been proven useful in the development of regional trauma systems as a tool to determine the optimal location of a new trauma center based on trauma-patient geospatial injury data and to minimize response times across the trauma network. Although the utility of artificial intelligence is apparent and proven in small pilot studies, its operationalization across the broader trauma system and trauma surgery space has been slow because of cost, stakeholder buy-in, and lack of expertise or knowledge of its utility. Nevertheless, as new trauma centers or systems are developed, or existing centers are retooled, machine learning and sophisticated analytics are likely to be important components to help facilitate decision-making in a wide range of areas, from determining bedside nursing and provider ratios to determining where to locate new trauma centers or emergency medical services teams.

Association of Coworker Reports About Unprofessional Behavior by Surgeons With Surgical Complications in Their Patients.

Importance: For surgical teams, high reliability and optimal performance depend on effective communication, mutual respect, and continuous situational awareness. Surgeons who model unprofessional behaviors may undermine a culture of safety, threaten teamwork, and thereby increase the risk for medical errors and surgical complications. Objective: To test the hypothesis that patients of surgeons with higher numbers of reports from coworkers about unprofessional behaviors are at greater risk for postoperative complications than patients whose surgeons generate fewer coworker reports. Design, Setting, and Participants: This retrospective cohort study assessed data from 2 geographically diverse academic medical centers that participated in the National Surgical Quality Improvement Program (NSQIP) and recorded and acted on electronic reports of safety events from coworkers describing unprofessional behavior by surgeons. Patients included in the NSQIP database who underwent inpatient or outpatient operations at 1 of the 2 participating sites from January 1, 2012, through December 31, 2016, were eligible. Patients were excluded if they were younger than 18 years on the date of the operation or if the attending surgeon had less than 36 months of monitoring for coworker reports preceding the date of the operation. Data were analyzed from August 8, 2018, through April 9, 2019. Exposures: Coworker reports about unprofessional behavior by the surgeon in the 36 months preceding the date of the operation. Main Outcomes and Measures: Postoperative surgical or medical complications, as defined by the NSQIP, within 30 days of the operation. Results: Among 13 653 patients in the cohort (54.0% [7368 ] female; mean [SD] age, 57 [16] years) who underwent operations performed by 202 surgeons (70.8% [143] male), 1583 (11.6%) experienced a complication, including 825 surgical (6.0%) and 1070 medical (7.8%) complications. Patients whose surgeons had more coworker reports were significantly more likely to experience any complication (0 reports, 954 of 8916 [10.7%]; ≥4 reports, 294 of 2087 [14.1%]; P < .001), any surgical complication (0 reports, 516 of 8916 [5.8%]; ≥4 reports, 159 of 2087 [7.6%]; P < .01), or any medical complication (0 reports, 634 of 8916 [7.1%]; ≥4 reports, 196 of 2087 [9.4%]; P < .001). The adjusted complication rate was 14.3% higher for patients whose surgeons had 1 to 3 reports and 11.9% higher for patients whose surgeons had 4 or more reports compared with patients whose surgeons had no coworker reports (P = .05). Conclusions and Relevance: Patients whose surgeons had higher numbers of coworker reports about unprofessional behavior in the 36 months before the patient's operation appeared to be at increased risk of surgical and medical complications. These findings suggest that organizations interested in ensuring optimal patient outcomes should focus on addressing surgeons whose behavior toward other medical professionals may increase patients' risk for adverse outcomes.

Tracheostomy risk factors and outcomes after severe traumatic brain injury.

OBJECTIVE: To determine risk factors associated with tracheostomy placement after severe traumatic brain injury (TBI) and subsequent outcomes among those who did and did not receive a tracheostomy. METHODS: This retrospective cohort study compared adult trauma patients with severe TBI (n = 583) who did and did not receive tracheostomy. A multivariable logistic regression model assessed the associations between age, sex, race, insurance status, admission GCS, AIS (Head, Face, Chest) and tracheostomy placement. Ordinal logistic regression models assessed tracheostomy's influence on ventilator days and ICU LOS. To limit immortal time bias, Cox proportional hazards models assessed mortality at 1, 3 and 12-months. RESULTS: In this multivariable model, younger age and private insurance were associated with increased probability of tracheostomy. AIS, ISS, GCS, race and sex were not risk factors for tracheostomy placement. Age showed a non-linear relationship with tracheostomy placement; likelihood peaked in the fourth decade and declined with age. Compared to uninsured patients, privately insured patients had an increased probability of receiving a tracheostomy (OR = 1.89 [95% CI = 1.09-3.23]). Mortality was higher in those without tracheostomy placement (HR = 4.92 [95% CI = 3.49-6.93]). Abbreviated injury scale-Head was an independent factor for time to death (HR = 2.53 [95% CI = 2.00-3.19]), but age, gender and insurance were not. CONCLUSIONS: Age and insurance status are independently associated with tracheostomy placement, but not with mortality after severe TBI. Tracheostomy placement is associated with increased survival after severe TBI.

Neurologic Functional and Quality of Life Outcomes after TBI: Clinic Attendees versus Non-Attendees.

This investigation describes the relationship between TBI patient demographics, quality of life outcome, and functional status outcome among clinic attendees and non-attendees. Of adult TBI survivors with intracranial hemorrhage, 63 attended our TBI clinic and 167 did not attend. All were telephone surveyed using the Extended-Glasgow Outcome Scale (GOSE), the Quality of Life after Brain Injury (QOLIBRI) scale, and a post-discharge therapy questionnaire. To determine risk factors for GOSE and QOLIBRI outcomes, we created multivariable regression models employing covariates of age, injury characteristics, clinic attendance, insurance status, post-discharge rehabilitation, and time from injury. Compared with those with severe TBI, higher GOSE scores were identified in individuals with both mild (odds ratio [OR]=2.0; 95% confidence interval [CI]: 1.1-3.6) and moderate (OR=4.7; 95% CI: 1.6-14.1) TBIs. In addition, survivors with private insurance had higher GOSE scores, compared with those with public insurance (OR=2.0; 95% CI: 1.1-3.6), workers' compensation (OR=8.4; 95% CI: 2.6-26.9), and no insurance (OR=3.1; 95% CI: 1.6-6.2). Compared with those with severe TBI, QOLIBRI scores were 11.7 points (95% CI: 3.7-19.7) higher in survivors with mild TBI and 17.3 points (95% CI: 3.2-31.5) higher in survivors with moderate TBI. In addition, survivors who received post-discharge rehabilitation had higher QOLIBRI scores by 11.4 points (95% CI: 3.7-19.1) than those who did not. Survivors with private insurance had QOLIBRI scores that were 25.5 points higher (95% CI: 11.3-39.7) than those with workers' compensation and 16.8 points higher (95% CI: 7.4-26.2) than those without insurance. Because neurologic injury severity, insurance status, and receipt of rehabilitation or therapy are independent risk factors for functional and quality of life outcomes, future directions will include improving earlier access to post-TBI rehabilitation, social work services, affordable insurance, and community resources.

Religiously affiliated intensive care unit patients receive more aggressive end-of-life care.

BACKGROUND: Previous studies among cancer patients have demonstrated that religious patients receive more aggressive end-of-life (EOL) care. We sought to examine the effect of religious affiliation on EOL care in the intensive care unit (ICU) setting. MATERIALS AND METHODS: We conducted a retrospective review of all patients admitted to any adult ICU at a tertiary academic center in 2010 requiring at least 2 d of mechanical ventilation. EOL patients were those who died within 30 d of admission. Hospital charges, ventilator days, hospital days, and days until death were used as proxies for intensity of care among the EOL patients. Multivariate analysis using multiple linear regression, zero-truncated negative binomial regression, and Cox proportional hazard model were used. RESULTS: A total of 2013 patients met inclusion criteria; of which, 1355 (67%) affirmed a religious affiliation. The EOL group had 334 patients, with 235 (70%) affirming a religious affiliation. The affiliated and nonaffiliated patients had similar levels of acuity. Controlling for demographic and medical confounders, religiously affiliated patients in the EOL group incurred 23% (P = 0.030) more hospital charges, 25% (P = 0.035) more ventilator days, 23% (P = 0.045) more hospital days, and 30% (P = 0.036) longer time until death than their nonaffiliated counterparts. Among all included patients, survival did not differ significantly among affiliated and nonaffiliated patients (log-rank test P = 0.317), neither was religious affiliation associated with a difference in survival on multivariate analysis (hazard ratio of death for religious versus nonreligious patients 0.95, P = 0.542). CONCLUSIONS: Compared with nonaffiliated patients, religiously affiliated patients receive more aggressive EOL care in the ICU. However, this high-intensity care does not translate into any significant difference in survival.

Disparities in trauma: the impact of socioeconomic factors on outcomes following traumatic hollow viscus injury.

BACKGROUND: This piece aims to examine the relationships between hollow viscus injury (HVI) and socioeconomic factors in determining outcomes. HVI has well-defined injury patterns with complex postoperative convalescence and morbidity, representing an ideal focus for identifying potential disparities among a homogeneous injury population. MATERIALS AND METHODS: A retrospective review included patients admitted to a level I trauma center with HVI from 2000-2009, as identified in the Trauma Registry of the American College of Surgeons. Patients with concomitant significant solid organ or vasculature injury were excluded. US Census (2000) median household income by zip code was used as socioeconomic proxy. Demographic and injury-related variables were also included. Endpoints were mortality and outcomes associated with HVI morbidity. RESULTS: A total of 933 patients with HVI were identified and 256 met inclusion criteria. There were 23 deaths (9.0%), and mortality was not associated with race, gender, income, or payer source. However, lower median household income was significantly associated with longer intervals to ostomy takedown (P = 0.032). Additionally, private payers had significantly lower rates of anastomotic leak (0% [0/73] versus 7.1% [13/183], P = 0.019) and fascial dehiscence (5.5% [4/73] versus 16.9% [31/183], P = 0.016), while self-payers had significantly higher rates of abscess formation, both overall (24% [24/100] versus 10.2% [16/156], P = 0.004) and among penetrating injuries (27.4% [23/84] versus 13.6% [12/88], P = 0.036). CONCLUSIONS: Socioeconomic status may not impact overall mortality among trauma patients with hollow viscus injuries, but private insurance appears to be protective of morbidity related to anastomotic leak, fascial dehiscence, and abscess formation. This supports that socioeconomic disparity may exist within long-term outcomes, particularly regarding payer source.

The success of traumatic brain injury registry outreach.

BACKGROUND: Traumatic brain injury (TBI) affects a large percentage of the US population. Survivors are under-served and recognized. The current mechanisms to contact patients and provide access to needed services appear ineffective. OBJECTIVE: To review the effectiveness of current TBI outreach using registries. METHODS: This study reviewed practices of the local TBI programme containing a registry utilized for outreach. Then, using a standardized questionnaire focusing on the TBI registry structure and its follow-up techniques, self-proclaimed registries were contacted and compared across the nation. RESULTS: Twelve additional TBI programmes were contacted. Eight others had actual registries used for follow-up. The principal mechanism was postal mail. Mail response rates varied from 0.54-25%. Programmes were limited by funding, staffing and access to contact information. CONCLUSION: Postal mail has not been a successful follow-up method for TBI registries. New structuring of letters and alternative contact techniques are needed. Improved access to those individuals with TBI's contact information and funding would likely also aid programmes managing this public health epidemic.

Emergency general surgery: definition and estimated burden of disease.

BACKGROUND: Acute care surgery encompasses trauma, surgical critical care, and emergency general surgery (EGS). While the first two components are well defined, the scope of EGS practice remains unclear. This article describes the work of the American Association for the Surgery of Trauma to define EGS. METHODS: A total of 621 unique International Classification of Diseases-9th Rev. (ICD-9) diagnosis codes were identified using billing data (calendar year 2011) from seven large academic medical centers that practice EGS. A modified Delphi methodology was used by the American Association for the Surgery of Trauma Committee on Severity Assessment and Patient Outcomes to review these codes and achieve consensus on the definition of primary EGS diagnosis codes. National Inpatient Sample data from 2009 were used to develop a national estimate of EGS burden of disease. RESULTS: Several unique ICD-9 codes were identified as primary EGS diagnoses. These encompass a wide spectrum of general surgery practice, including upper and lower gastrointestinal tract, hepatobiliary and pancreatic disease, soft tissue infections, and hernias. National Inpatient Sample estimates revealed over 4 million inpatient encounters nationally in 2009 for EGS diseases. CONCLUSION: This article provides the first list of ICD-9 diagnoses codes that define the scope of EGS based on current clinical practices. These findings have wide implications for EGS workforce training, access to care, and research.

Tennessee emergency hand care distributions and disparities: Emergent hand care disparities.

BACKGROUND: Hand trauma is the most frequently treated injury in emergency departments, but presently there is a crisis of insufficient emergency coverage. This study evaluates the discrepancy of emergent and elective hand care trends based on socioeconomic factors in the state of Tennessee. METHODS: We identified 119 hospitals in Tennessee that contained operating and emergency room facilities. Of these, 111 hospitals participated in a survey to determine the availability of elective and emergency hand surgery. Wilcoxon rank-sum test or permutation chi-square test and logistic regression were used to analyze reported measures. RESULTS: Our results revealed that hospitals in counties with the lowest per capita income and median household income are less likely to have hand specialists or offer hand call. There are also significantly fewer hospitals that have hand specialists and offer hand call that are located in medically underserved areas. In the state of TN, level 1 trauma facilities are required by the Tennessee Department of Health to have staffed hand specialists and 24/7 hand call. Our study revealed that while 7/8 (87.5 %) level 1 trauma facilities have hand specialists, only 2/8 (25 %) provide 24/7 hand specialist call. CONCLUSION: Our results strongly suggest the presence of a health care disparity for hand trauma in counties with a low income and in medically underserved areas.

O' surgery case log data, where art thou?

BACKGROUND: The American College of Surgeons (ACS) Case Log represents a data system that satisfies the American Board of Surgery (ABS) Maintenance of Certification (MOC) program, yet has broad data fields for surgical subspecialties. Using the ACS Case Log, we have developed a method of data capture, categorization, and reporting of acute care surgery fellows' experiences. STUDY DESIGN: In July 2010, our acute care surgery fellowship required our fellows to log their clinical experiences into the ACS Case Log. Cases were entered similar to billable documentation rules. Keywords were entered that specified institutional services and/or resuscitation types. These data were exported in comma separated value format, deidentified, structured by Current Procedural Terminology (CPT) codes relevant to acute care surgery, and substratified by fellow and/or fellow year. RESULTS: Fifteen report types were created consisting of operative experience by service, procedure by major category (cardiothoracic, vascular, solid organ, abdominal wall, hollow viscus, and soft tissue), total resuscitations, ultrasound, airway, ICU services, basic neurosurgery, and basic orthopaedics. Results are viewable via a secure Web application, accessible nationally, and exportable to many formats. CONCLUSIONS: Using the ACS Case Log satisfies the ABS MOC program requirements and provides a method for monitoring and reporting acute care surgery fellow experiences. This system is flexible to accommodate the needs of surgical subspecialties and their training programs. As documentation requirements expand, efficient clinical documentation is a must for the busy surgeon. Although, our data entry and processing method has the immediate capacity for acute care surgery fellowships nationwide, multiple larger decisions regarding national case log systems should be encouraged.

Using the National Surgical Quality Improvement Program and the Tennessee Surgical Quality Collaborative to improve surgical outcomes.

BACKGROUND: Led by the Tennessee Chapter of the American College of Surgeons, in May 2008 a 10-hospital collaborative was formed between the Tennessee Chapter of ACS, the Tennessee Hospital Association, and the BlueCross BlueShield of Tennessee Health Foundation. We hypothesized that by forming the Tennessee Surgical Quality Collaborative using the National Surgical Quality Improvement Program (NSQIP) system to share surgical process and outcomes data, overall patient surgical outcomes would improve. STUDY DESIGN: All NSQIP data from the 10-hospital collaborative for the time periods January to December 2009 (period 1) and January to December 2010 (period 2) were collected. Data on 20 categories of postoperative complications and 30-day mortality were compared between periods. Complication comparisons and hospital costs associated with complications were calculated per 10,000 procedures. Statistical analysis was performed by Z-test. RESULTS: There were 14,205 total surgical cases in period 1 and 14,901 surgical cases in period 2. Between periods (per 10,000 cases) there were significant improvements in superficial surgical site infections (-19%, p = 0.0005), on ventilator longer than 48 hours (-15%, p = 0.012), graft/prosthesis/flap failure (-60%, p < 0.0001), acute renal failure (-25%, p = 0.023), and wound disruption (-34%, p = 0.011). Although mortality (per 10,000) was higher in period 2 (237.6 vs 232.3), no statistical difference was noted. Net costs avoided between these periods were calculated as $2,197,543 per 10,000 general and vascular surgery cases. CONCLUSIONS: Data organization and scrutiny are the initial steps of process improvement. Participation in our regional surgical quality collaborative resulted in improved outcomes and reduced costs. Although the mechanisms for these changes are likely multifactorial, the collaborative establishes communication, process improvement, and frank discussion among the members as best practices are identified and shared and standardized processes are adopted.

Feeding the open abdomen.

BACKGROUND: The purpose of this study was to determine if early enteral nutrition improves outcome for trauma patients with an open abdomen (OA). METHODS: Retrospective review was used to identify 78 patients who required an OA for >or=4 hospital days, survived, and had available nutrition data. Demographic data and nutrition data comprising enteral nutrition initiation day and daily % target goal were collected. Patients were divided into 2 groups: early enteral feeding (EEN), initiated 4 days). Outcomes included infectious complications, early closure of the abdominal cavity (<8 days from original celiotomy), and fistula formation. RESULTS: Fifty-three of 78 (68%) patients were men, with a mean age of 35 years; 74% had blunt trauma. Forty-three of 78 (55%) patients had EEN, whereas 35 of 78 (45%) had LEN. There was no difference with respect to demographics, injury severity, or infectious complication rates. Thirty-two of 43 (74%) patients with EEN had early closure of the abdominal cavity, whereas 17 of 35 (49%) patients with late feeding had early closure (p = .02). Four of 43 (9%) patients with EEN demonstrated fistula formation, whereas 9 of 35 (26%) patients with late feeding formed fistulae (p = .05). The EEN group had lower hospital charges (p = .04) by more than $50,000. CONCLUSIONS: EEN in the OA was associated with (1) earlier primary abdominal closure, (2) lower fistula rate, (3) lower hospital charges.

The open abdomen in trauma: do infectious complications affect primary abdominal closure?

OBJECTIVE: One of the primary goals of damage control surgery in the trauma patient is primary closure of the abdomen. We hypothesized that extra-abdominal infections, such as those complicating injuries to the thorax, diaphragm, long bones, or musculoskeletal system, would decrease the likelihood of primary abdominal closure and increase hospital resource utilization in patients requiring open abdominal management. METHODS: The trauma registry of the American College of Surgeons (TRACS) was reviewed retrospectively from 1995-2002 for open abdomen technique and damage control surgery. The outcome was primary fascial closure or delayed closure. Patients who died prior to closure were excluded. We evaluated infectious complications, including ventilator-associated pneumonia (VAP), blood stream infection (BSI), and surgical site infection (SSI). Other parameters studied were multiple rib fractures, long bone fractures, chest injuries, diaphragm injuries, empyema, and transfusion requirements. Hospital charges were obtained from the hospital administrative database. Univariate, multivariate, and regression analyses were performed to identify the effects of infectious complications on primary abdominal closure, length of stay, total hospital charges, and disposition. RESULTS: Three hundred forty-four patients required the open abdomen technique: 67% received damage control laparotomy and 33% decompression of abdominal compartment syndrome. Two hundred seventy-six patients (80%) went on to abdominal closure of some form and constituted the primary study group. Primary abdominal closure was achieved in 180 (65%) with a mean time to closure of 3.5 days. Ventilator-associated pneumonia, BSI, and SSI were associated with lack of primary closure (p < 0.05). Increased blood transfusions also were associated with failure of primary closure (p < 0.05). Ventilator-associated pneumonia and BSI were associated with significantly greater lengths of stay in the intensive care unit (ICU) (24.2 days vs. 12.6 days and 30.5 days vs. 17.9 days; both p < 0.0001) and significantly greater total hospital charges (232,080 US dollar vs. 142,893 US dollar; 247,440 US dollar vs. 160,940 US dollar; and 264,778 US dollar vs. 170,447 US dollar; all p < 0.001). CONCLUSION: Inability to achieve primary abdominal closure was associated with infectious complications (VAP, BSI, and SSI) and large transfusion requirements. Infectious complications also significantly increased ICU utilization and hospital charges. Death was associated with BSI, femur fractures, and large transfusion requirements, whereas infectious complications did not have a significant impact on discharge disposition.

Cerebral cortical oxygenation: a pilot study.

BACKGROUND: Cerebral hypoxia (cerebral cortical oxygenation [Pbro2] < 20 mm Hg) monitored by direct measurement has been shown in animal and small clinical studies to be associated with poor outcome. We present our preliminary results observing Pbro2 in patients with traumatic brain injury (TBI). METHODS: A prospective observational cohort study was performed. Institutional review board approval was obtained. All patients with TBI who required measurement of intracranial pressure (ICP), cerebral perfusion pressure (CPP), and Pbro2 because of a Glasgow Coma Scale score < 8 were enrolled. Data sets (ICP, CPP, Pbro2, positive end-expiratory pressure (PEEP), Pao2, and Paco2) were recorded during routine manipulation. Episodes of cerebral hypoxia were compared with episodes without. Results are displayed as mean +/- SEM; t test, chi2, and Fisher's exact test were used to answer questions of interest. RESULTS: One hundred eighty-one data sets were abstracted from 20 patients. Thirty-five episodes of regional cerebral hypoxia were identified in 14 patients. Compared with episodes of acceptable cerebral oxygenation, episodes of cerebral hypoxia were noted to be associated with a significantly lower mean Pao2 (144 +/- 14 vs. 165 +/- 8; p < 0.01) and higher mean PEEP (8.8 +/- 0.7 vs. 7.1 +/- 0.3; p < 0.01). Mean ICP and CPP measurements were similar between groups. In a univariate analysis, cerebral hypoxic episodes were associated with Pao2 < or = 100 mm Hg (p < 0.01) and PEEP > 5 cm H2O (p < 0.01), but not ICP > 20 mm Hg, CPP < or = 65 mm Hg, or Pac2 < or = 35 mm Hg. CONCLUSION: Cerebral oxymetry is confirmed safe in the patient with multiple injuries with TBI. Occult cerebral hypoxia is present in the traumatic brain injured patient despite normal traditional measurements of cerebral perfusion. Further research is necessary to determine whether management protocols aimed at the prevention of cerebral cortical hypoxia will affect outcome.
