Serious traumatic brain injury: An evaluation of functional outcomes

Michael L. Hawkins; F. D. Lewis; Regina S. Medeiros

OBJECTIVES Evaluate independent living, productivity, and social outcomes of patients with serious traumatic brain injury (TBI) after inpatient rehabilitation. METHODS Fifty-five adults with serious TBI (Abbreviated Injury Scale score > or = 3) were admitted to a Level I trauma center and subsequently transferred to a comprehensive inpatient rehabilitation hospital (Walton Rehabilitation Hospital). Functional Independence Measures were obtained at admission (Adm), discharge (D/C), and at 3- (n = 52) and 1-year (n = 51) follow-up. RESULTS At 1 year, 90% of the patients were living at home. Eight (16%) required full-time supervision, while 41 (82%) were independent of supervision throughout most of the day. Thirteen (25%) patients had returned to work, eight full time and five with reduced responsibility and fewer hours than before injury. Nineteen shared household duties, while eight (16%) had primary responsibility. Fourteen (27%) patients demonstrated socially inappropriate or disruptive behavior at least weekly. [table: see text] CONCLUSION Although cognitive skills were diminished for the majority of patients, many achieved a substantial reduction in disability within 18 months after TBI.

BACKGROUND Nonoperative management (NOM) of solid abdominal organ injury (SAOI) is increasing. Consequently, training programs are challenged to ensure essential operative trauma experience. We hypothesize that the increasing use and success of NOM for SAOI negatively impacts resident operative experience with these injuries and that curriculum-based simulation might be necessary to augment clinical experience. MATERIALS AND METHODS A retrospective cohort analysis of 1198 consecutive adults admitted to a Level I trauma center over 12 y diagnosed with spleen and/or liver injury was performed. Resident case logs were reviewed to determine operative experience (Cohort A: 1996-2001 versus Cohort B: 2002-2007). RESULTS Overall, 24% of patients underwent operation for SAOI. Fewer blunt than penetrating injuries required operation (20% versus 50%, P < 0.001). Of those managed operatively, 70% underwent a spleen procedure and 43% had a liver procedure. More patients in Cohort A received an operation compared with Cohort B (34% versus 16%, P < 0.001). Patient outcomes did not vary between cohorts. Over the study period, 55 residency graduates logged on average 27 ± 1 operative trauma cases, 3.4 ± 0.3 spleen procedures, and 2.4 ± 0.2 liver operations for trauma. Cohort A graduates recorded more operations for SAOI than Cohort B graduates (spleen 4.1 ± 0.4 versus 3.0 ± 0.2 cases, P = 0.020 and liver 3.2 ± 0.3 versus 1.8 ± 0.3 cases, P = 0.004). CONCLUSIONS Successful NOM, especially for blunt mechanisms, diminishes traditional opportunities for residents to garner adequate operative experience with SAOI. Fewer operative occasions may necessitate an increased role for standardized, curriculum-based simulation training.

BACKGROUND Few interdisciplinary research groups include basic scientists, pharmacists, therapists, nutritionists, laboratory technicians, as well as trauma patients and families, in addition to clinicians. Increasing interprofessional diversity within scientific teams working to improve trauma care is a goal of national organizations and federal funding agencies such as the National Institutes of Health (NIH). This article describes the design, implementation, and outcomes of a Trauma Interdisciplinary Group for Research (TIGR) at a Level 1 trauma center as it relates to increasing research productivity, with specific examples excerpted from an ongoing NIH-funded study. METHODS We used a pretest/posttest design with objectives aimed at measuring increases in research productivity following a targeted intervention. A SWOT (strengths, weaknesses, opportunities, and threats) analysis was used to develop the intervention, which included research skill-building activities, accomplished by adding multidisciplinary investigators to an existing NIH-funded project. The NIH project aimed to test the hypothesis that accelerated biologic aging from chronic stress increases baseline inflammation and reduces inflammatory response to trauma (projected n = 150). Pre-TIGR/post-TIGR data related to participant screening, recruitment, consent, and research processes were compared. Research productivity was measured through abstracts, publications, and investigator-initiated projects. RESULTS Research products increased from 12 to 42 (approximately 400%). Research proposals for federal funding increased from 0 to 3, with success rate of 66%. Participant screenings for the NIH-funded study increased from 40 to 313. Consents increased from 14 to 70. Laboratory service fees were reduced from

5 per participant. CONCLUSION Adding diversity to our scientific team via TIGR was exponentially successful in (1) improving research productivity, (2) reducing research costs, and (3) increasing research products and mentoring activities that the team before TIGR had not entertained. The team is now well positioned to apply for more federally funded projects, and more trauma clinicians are considering research careers than before.

BACKGROUND Identifying predictors of length of stay in the intensive care unit can help critical care clinicians prioritize care in patients with acute, life-threatening injuries. OBJECTIVE To determine if systemic inflammatory response syndrome scores are predictive of length of stay in the intensive care unit in patients with acute, life-threatening injuries. METHODS Retrospective chart reviews were completed on patients with acute, life-threatening injuries admitted to the intensive care unit at a level I trauma center in the southeastern United States. All 246 eligible charts from the trauma registry database from 1998 to 2007 were included. Systemic inflammatory response syndrome scores measured on admission were correlated with length of stay in the intensive care unit. Data on race, sex, age, smoking status, and injury severity score also were collected. Univariate and multivariate regression modeling was used to analyze data. RESULTS Severe systemic inflammatory response syndrome scores on admission to the intensive care unit were predictive of length of stay in the unit (F=15.83; P<.001), as was white race (F=9.7; P=.002), and injury severity score (F=20.23; P<.001). CONCLUSIONS Systemic inflammatory response syndrome scores can be measured quickly and easily at the bedside. Data support use of the score to predict length of stay in the intensive care unit.

BACKGROUND States struggle to continue support for recruitment, funding and development of designated trauma centers (DTCs). The purpose of this study was to evaluate the probability of survival for injured patients treated at DTCs versus nontrauma centers. METHODS We reviewed 188,348 patients from the state’s hospital discharge database and identified 13,953 severely injured patients admitted to either a DTC or a nontrauma center between 2008 and 2012. DRG International Classification of Diseases—9th Rev. Injury Severity Scores (ICISS), an accepted indicator of injury severity, was assigned to each patient. Severe injury was defined as an ICISS less than 0.85 (indicating ≥15% probability of mortality). Three subgroups of the severely injured patients were defined as most critical, intermediate critical, and least critical. A full information maximum likelihood bivariate probit model was used to determine the differences in the probability of survival for matched cohorts. RESULTS After controlling for injury severity, injury type, patient demographics, the presence of comorbidities, as well as insurance type and status, severely injured patients treated at a DTC have a 10% increased probability of survival. The largest improvement was seen in the intermediate subgroup. CONCLUSION Treatment of severely injured patients at a DTC is associated with an improved probability of survival. This argues for continued resources in support of DTCs within a defined statewide network. LEVEL OF EVIDENCE Epidemiologic study, level III.

BACKGROUND Led by the American College of Surgeons Trauma Quality Improvement Program, performance improvement efforts have expanded to regional and national levels. The American College of Surgeons Trauma Quality Improvement Program recommends 5 audit filters to identify records with erroneous data, and the Georgia Committee on Trauma instituted standardized audit filter analysis in all Level I and II trauma centers in the state. STUDY DESIGN Audit filter reports were performed from July 2013 to September 2014. Records were reviewed to determine whether there was erroneous data abstraction. Percent yield was defined as number of errors divided by number of charts captured. RESULTS Twelve centers submitted complete datasets. During 15 months, 21,115 patient records were subjected to analysis. Audit filter captured 2,901 (14%) records and review yielded 549 (2.5%) records with erroneous data. Audit filter 1 had the highest number of records identified and audit filter 3 had the highest percent yield. Individual center error rates ranged from 0.4% to 5.2%. When comparing quarters 1 and 2 with quarters 4 and 5, there were 7 of 12 centers with substantial decreases in error rates. The most common missed complications were pneumonia, urinary tract infection, and acute renal failure. The most common missed comorbidities were hypertension, diabetes, and substance abuse. CONCLUSIONS In Georgia, the prevalence of erroneous data in trauma registries varies among centers, leading to heterogeneity in data quality, and suggests that targeted educational opportunities exist at the institutional level. Standardized audit filter assessment improved data quality in the majority of participating centers.

Background:Recent efforts by the Accreditation Council for Graduate Medical Education to standardize resident education and demonstrate objective clinical proficiency have led toward more accurate documentation of resident competencies. Particularly with regard to bedside procedures, hospitals are now requiring certification of competency before allowing a provider to perform them independently. The current system at our institution uses a time-consuming, online verification system. This study provided an alternative method through an identification card with a list of bedside procedures. Our aim was an easier verification method for nurses, allowing fewer delays of bedside procedures and more time for nursing to patient care. Methods:We performed a prospective, controlled study, using general surgical residents and surgical intensive care nurses. Subjects performed an initial survey of their experience with the current online system in place to identify resident bedside procedure competency. Phase I involved educating the subjects about this current system followed by another survey. Phase II involved introducing our proficiency card. After 3 months, we conducted a final survey to evaluate opinions on the proficiency card, comparing it with the online verification method. Results:Nursing postintervention responses indicated that significantly less time was required to validate a residents proficiency (P = .04). Prior to the introduction of the proficiency card, only 15% of nurses reported a verification time of 5 minutes or less, compared with 64% postintervention. In addition, nurses rated the card validation as an easier, more efficient method of verification (P = .02). Conclusions:We believe that its continued use will not only improve the adherence to a mandatory hospital policy but also result in a less-cumbersome verification process, allowing more time for physician and nurse-to-patient care.

Background The American College of Surgeons Needs Based Assessment of Trauma Systems (NBATS) tool was developed to help determine the optimal regional distribution of designated trauma centers (DTC). The objectives of our current study were to compare the current distribution of DTCs in Georgia with the recommended allocation as calculated by the NBATS tool and to see if the NBATS tool identified similar areas of need as defined by our previous analysis using the International Classification of Diseases, Ninth Revision, Clinical Modification Injury Severity Score (ICISS). Methods Population counts were acquired from US Census publications. Transportation times were estimated using digitized roadmaps and patient zip codes. The number of severely injured patients was obtained from the Georgia Discharge Data System for 2010 to 2014. Severely injured patients were identified using two measures: ICISS<0.85 and Injury Severity Score >15. Results The Georgia trauma system includes 19 level I, II, or III adult DTCs. The NBATS guidelines recommend 21; however, the distribution differs from what exists in the state. The existing DTCs exactly matched the NBATS recommended number of level I, II, or III DTCs in 2 of 10 trauma service areas (TSAs), exceeded the number recommended in 3 of 10 TSAs, and was below the number recommended in 5 of 10 TSAs. Densely populated, or urban, areas tend to be associated with a higher number of existing centers compared with the NBATS recommendation. Other less densely populated TSAs are characterized by large rural expanses with a single urban core where a DTC is located. The identified areas of need were similar to the ones identified in the previous gap analysis of the state using the ICISS methodology. Discussion The tool appears to underestimate the number of centers needed in extensive and densely populated areas, but recommends additional centers in geographically expansive rural areas. The tool signifies a preliminary step in assessing the need for state-wide inpatient trauma center services. Level of evidence Economic, level IV.
