Missed injuries in a level I trauma center

BACKGROUND: Major trauma presents major diagnostic and therapeutic problems. Any delay in providing the treatment necessary may lead to increased morbidity and mortality, prolonged length of hospital stay, and increased cost. This study was undertaken to determine the extent, contributing factors, and implication of missed injuries and relate them to the three surveys in a Danish Level I trauma center. METHODS: The records of all major traumatized patients admitted to the Odense University Hospital from January 1996 through December 1999 have been studied to determine the extent and type of missed injuries. The initial examination is carried out by the trauma team in the A&E department according to standard protocols. Resuscitation is carried out according to Advanced Trauma Life Support principles and details are documented in the patient journal and in a special trauma journal. RESULTS: Sixty-four of 786 patients (incidence, 8.1%) had 86 missed injuries. The missed injuries averaged 1.3 injuries per patient. There were 45 male and 19 female patients, with a median age of 33 years (range, 12-81 years). The median ISS was 17 (range, 4-50); 14%, 38%, and 48% of the injuries were missed in primary, secondary, and tertiary surveys, respectively. CONCLUSION: Our study demonstrates that missed injuries can occur at any stage of the management of patients with major trauma. Repeated assessments, both clinical and radiologic, are mandatory to diminish the problem. In initial assessment, one still has to treat the greatest threat to life before complete diagnosis of all injuries, but alertness to evolving injuries must remain throughout the patient's stay in hospital.     

Patterns and implications of lower extremity injuries in a community level I trauma center

This study examined specific types of lower extremity injuries, their treatment, and trends in length of stay (LOS) as seen in an academic community hospital. The authors' trauma registry was queried for lower extremity injuries requiring surgical intervention from 1992 to 2000. A total of 5567 patients were identified. A total of 574 patients with 857 injuries met the criteria. The only significant difference in injury severity score among various injury types was found between traumatic amputations and open fractures (P = 0.006). However, there was no statistical difference between these 2 groups with regard to LOS. Patients requiring 1 or 2 procedures had a significantly shorter LOS than those requiring 3 procedures (P = 0.002 and P = 0.021 respectively). In this population of patients, it was not the manner of initial reconstruction, but the number of reconstructive procedures required that had an impact on LOS. LOS reduction might be possible when patients with lower injury severity scores can be treated in a more efficient manner.     

Profile of chest trauma in a level I trauma center

BACKGROUND: Chest injuries are seen with increasing frequency in urban hospitals. The profile of chest injuries depends on the size of the hospital and the level of trauma center. The data regarding the true incidence of chest trauma are scant. METHODS: One thousand three hundred fifty-nine consecutive patients seen at a Level I trauma center were analyzed. The nature of injury, methods of treatment, and morbidity and mortality were recorded in a prospective manner and analyzed retrospectively. Multiple logistic regression analysis was used to determine the independent predictors of mortality after chest trauma. RESULTS: The overall mortality was 9.41%. Low Glasgow Coma Scale score, older age, presence of penetrating chest injury, long bone fractures, fracture of more than five ribs, and liver and spleen injuries were independent predictors of death after chest trauma. A model was created for predicting the mortality based on various factors. CONCLUSION: Most chest injuries can be treated with simple observation. Only 18.32% of patients required tube thoracostomy and 2.6% needed thoracotomy. Low Glasgow Coma Scale score and advanced age are the most significant independent predictors of mortality.     

Impact of the 80-hour workweek on patient care at a level I trauma center

HYPOTHESIS: The 80-hour workweek limitation for surgical residents is associated with an increase in mortality and complication rates among adult trauma surgical patients. DESIGN: Retrospective cohort study. SETTING: Academic level I trauma center. PATIENTS: Trauma patients admitted before and after the 80-hour workweek limitation. METHODS: We compared death and complication rates for adult trauma patients admitted during a 24-month period before (2001-2003) and a 24-month period after (2004-2006) implementation of the 80-hour workweek at our institution. Relative risk and its 95% confidence intervals were examined. MAIN OUTCOME MEASURES: Patient care outcomes included preventable and nonpreventable complications and deaths. RESULTS: The patient populations from the 2 time periods were clinically similar. No significant differences were found in the total and the preventable death rates. The time period after the 80-hour workweek mandate had a significantly higher total complication rate (5.64% vs 7.28%; relative risk, 1.29; 95% confidence interval, 1.15-1.45; P < .001), preventable complication rate (0.89% vs 1.28%; relative risk, 1.43; 95% confidence interval, 1.06-1.91; P = .02), and nonpreventable complication rate (4.75% vs 5.81%; relative risk, 1.22; 95% confidence interval, 1.08-1.39; P = .002). CONCLUSION: Although there was no difference in deaths between the 2 time periods, there was a significant increase in total, preventable, and nonpreventable complications. This increase in complication rate may be due, in part, to the new 80-hour workweek policy.     

Popliteal artery trauma in a rural level I trauma center

Popliteal vascular trauma has historically been an urban phenomenon. We hypothesized that rural popliteal artery injury would result more often from blunt mechanisms of injury (MOI), have a longer time to operation, and result in a higher amputation rate. We retrospectively reviewed all cases of popliteal artery injury from December 1994 to May 2001 at our rural trauma center. Age, gender, Injury Severity Score (ISS), MOI, scene transport versus transfer from a referring hospital, time to operation, and operative times were studied. Significance was determined by Student's t test with a P value < or = 0.05. Thirty-two popliteal artery injuries were found. Blunt trauma accounted for 50 per cent of the injuries. Eighty-eight per cent of the patients were transferred from a referring hospital. Patients transported directly from the scene had a higher ISS. Longer operative times translated into an increased need for fasciotomy. The amputation rate was 19 per cent. This is the first attempt to delineate the specific nature of rural popliteal artery trauma. The amputation rate was not different between the two different MOI and was independent of the time to operation. Of those patients receiving an amputation 83 per cent were transferred from another hospital and despite a statistically lower ISS still required an amputation.     

Appropriateness of patients transferred with orthopedic injuries: experience of a level I trauma center

Background

Trauma patients are frequently transferred to a higher level of care for specialized orthopedic care. Many of these transfers are not necessary and waste valuable resources. The purpose of this study was to quantify our own experience and to assess the appropriateness of orthopedic transfers to a level I trauma center emergency department.

Methods

A retrospective review of orthopedic emergency department transfers to a level I trauma center was performed. Data collected included time of transfer, injury severity score (ISS), age, gender, race, orthopedic coverage at transfer institution, and insurance status. Two orthopedic trauma surgeons graded the appropriateness of transfer. A weighted logistic regression model was used to compare dependent and independent variables.

Results

A total of 324 patient transfers were reviewed; 65 (20.1%) of them were graded as inappropriate. There was no statistically significant relationship between appropriateness of transfer and age, availability of orthopedic coverage, night/weekend transfer, or insurance status. Regression analysis showed that only ISS (OR 1.130, p = .008) and “polytrauma” (OR 25.39, p < .0001) designation were associated with increased odds ratio of appropriate transfer. The kappa coefficient for inter-rater reliability between the two raters was 0.505 (95% CI, 0.388–0.623) reflecting moderate agreement.

Conclusion

Inappropriate transfers create a significant medical burden to our health care system using valuable resources. Our study found similar results of inappropriate transfers compared to previous studies. However, we did not find a relationship between insurance status or nights/weekends and transfer appropriateness.

     

Management of upper extremity arterial injuries at an urban level I trauma center

Although relatively uncommon, upper extremity arterial injuries are serious and may significantly impact the outcome of the trauma patient. Management of upper extremity arterial injuries at an urban level I trauma center was reviewed to determine incidence, assess the current management strategy, and evaluate hospital outcome. Upper extremity trauma patients with arterial injury who presented between January 2005 and December 2006 were included in this retrospective review. Data collected included age, gender, race, mechanism of injury, type of injury, associated upper extremity injuries, concomitant injuries, injury severity score (ISS), diagnostic modalities employed, surgical procedures and interventions, mortality, length of stay, and discharge disposition. Statistical analysis between blunt and penetrating arterial injuries as well as between proximal and distal arterial injuries also was conducted. During a 2-year period, 28 patients with 30 upper extremity arterial injuries were admitted, yielding an incidence of 0.48%. The study population was comprised primarily of young Caucasian males, with a mean ISS of 9.0. The majority (89.3%) of patients suffered concomitant upper extremity injuries. Twenty-two nerve injuries were identified in 16 (57.1%) patients. The most common injury mechanism was cut by glass (39.3%). Arterial injuries were categorized into 18 (60.0%) penetrating and 12 (40.0%) blunt injuries. Involved artery distribution was as follows: 12 (40.0%) brachial, eight (26.7%) ulnar, seven (23.3%) radial, and three (10.0%) axillary. Over half (56.7%) of the injuries resulted from lacerations. Injuries were managed as follows: 14 (46.7%) primary repairs, eight (26.7%) ligations, six (20.0%) saphenous vein graft bypasses, and two (6.7%) endovascular procedures. Eleven (39.3%) patients required intensive care unit (ICU) admission. The overall mean length of hospitalization for these patients was 7.4 days compared to a mean length of hospitalization of 2.0 days for the 17 (44.7%) patients who did not require ICU admission. The overall limb salvage rate was 96.4% as arterial injuries were successfully repaired in 27 of 28 patients. No patients expired and all were discharged home. Equivalent demographics, mechanisms of injury, surgical management approaches, and successful hospital outcomes were demonstrated between penetrating and blunt injuries as well as between proximal and distal arterial injuries. The current management approach, including use of angiography and prompt surgical management, results in successful outcomes after upper extremity arterial injuries and will continue to be utilized.

The evolution of trauma care at a level I trauma center

BACKGROUND: My colleagues and I compared trauma patient demographics and outcomes between two time periods in the last 10 years in our Level I trauma center to evaluate the impact of the marked evolution in trauma care and determine additional opportunities for improvement. METHODS: Our trauma registry was queried for adult trauma patients admitted from 1991 to 1993 (EARLY) and 1999 to 2001 (LATE). The EARLY period predated creation and maturation of a dedicated trauma service and Level I trauma center verification. Continuous data were compared using Student's t-test, and categorical data using chi-square. RESULTS: Increased transfers of severely injured patients from regional hospitals, combined with fewer admissions for "observation," resulted in fewer, but sicker, patients admitted in the LATE period. Patients were considerably older in the LATE period and mortality was higher. Despite higher acuity of patients, hospital and ICU lengths of stay were shorter in the LATE period. Nonoperative management of solid organ injuries was more common in the LATE period, but the overall operative volume was similar. Nonsurvivors in the LATE period had higher Injury Severity Scores and were older compared with the EARLY period. Mortality attributable to blunt CNS injury was higher, and that attributed to late sepsis and multiple organ failure was lower in the LATE period. CONCLUSIONS: Over the past decade, more older, severely injured patients have been admitted to our Level I trauma center. Overall mortality among these higher acuity patients has increased, with a marked shift in attributable mortality to CNS injury and away from late sepsis and multiple organ failure. This highlights the need for continued efforts to identify optimal management strategies for severe brain injury. Additional areas for improvement include enhancement of our regional trauma network and injury prevention initiatives.     

Correlating weather and trauma admissions at a level I trauma center

BACKGROUND: Popular emergency room wisdom touts higher temperatures, snowfall, weekends, and evenings as variables that increase trauma admissions. This study analyzed the possible correlation between trauma admissions and specific weather variables, and between trauma admissions and time of day or season. METHODS: Trauma admission data from a Level I trauma center database from July 1, 1996 to January 31, 2002 was downloaded and linked with local weather data from the Archives of the National Oceanic and Atmospheric Administration website, and then analyzed. RESULTS: There were 8,269 trauma admissions over a total of 48,984 hours for an average of one admission every 6 hours. Daily high temperature and precipitation were valid predictors of trauma admission volume, with a 5.25% increase in hourly incidents for each 10-degree difference in temperature, and a 60% to 78% increase in the incident rate for each inch of precipitation in the previous 3 hours. CONCLUSIONS: Weather and seasonal variations affect admissions at a Level I trauma center. Data from this study could be useful for determining staffing requirements and resource allocation.     

All-terrain vehicle injuries. A review at a rural level II trauma center

All-terrain vehicles (ATVs) have become a major source of morbidity and mortality with more than 600 deaths nationwide. Nearly half of those injured are children under 16 years. Twenty three ATV accidents were seen at the Guthrie Medical Center over a 30 month period ending in August 1986. Ten patients (43.5%) were under 16 years old. Of those injured who were older, alcohol was involved in 70 per cent of the accidents. Five accidents occurred on highways (21.7%), in spite of laws banning their use on public roads. Rollover type accidents and collisions were the most frequent mechanisms of injury (39% and 35%). Of 18 patients known not to have worn a helmet, 61 per cent sustained a closed head injury. In all, there were 88 injuries in 23 patients. Common injuries included lacerations (13), long bone fractures (13), renal contusions (11) and head injury (11). There were two deaths (8.7%), two cord transections with permanent disability, and a below-knee amputation. ATVs present a serious hazard to adult and children riders alike. Age limits, state licensing, safety programs, and protective equipment are all recommended as a means to reduce injury and death from recreational riding.     

Impact of a voluntary trauma system on mortality, length of stay, and cost at a level I trauma center

Trauma systems have been shown to decrease injury-related mortality; however, their development has been slow often requiring legislative codification. The purpose of this study was to evaluate the impact of a voluntary regional trauma system on outcomes at a Level I trauma center. We conducted a retrospective cohort study in an American College of Surgeons-verified Level I trauma center including all patients admitted to a Level I trauma center during the periods April 1995 through March 1996 (T-1) and April 1997 through March 1998 (T-2). Our main outcome measures were in-hospital mortality, hospital length of stay, cost of care Compared with T-1 patients T-2 patients had lower mortality (odds ratio 0.48, 95% confidence interval 0.32-0.71). A similar decline in mortality was observed for the entire six-county region compared with the remainder of the state. Among the most severely injured patients (Injury Severity Score > or = 16) T-2 patients had a shorter length of stay (16.5 vs 19.5 days; P < 0.05) and lower mean cost of care ($29,795 vs $34,983; P < 0.05). A voluntary trauma system can be implemented without the need for legislative mandate. After system implementation patient and financial outcomes were improved at an individual Level I trauma center.     

Pelvic fractures in a pediatric level I trauma center

OBJECTIVES: Assess the characteristics associated with the risk of complications and mortality in children sustaining pelvic fractures. SETTING: Urban university pediatric Level I trauma center in a large metropolitan community. PATIENTS/PARTICIPANTS: Retrospective analysis of 57 consecutive children with 66 pelvic fractures seen between 1993 and 1999. INTERVENTION: Fifty-two patients were treated nonoperatively, and five patients required operative stabilization (four acetabular fractures and one partial sacroiliac joint disruption). MAIN OUTCOME MEASURE: Type and cause of pelvic fracture, type of management used, incidence of associated injuries, hemorrhage requiring transfusion, and mortality. RESULTS: Hemorrhage directly related to the pelvic fracture occurred in only one patient (2%), whereas 11 other patients required transfusions associated with other body-area injuries. Three patients with pelvic fractures died (5%), but deaths were due to other body-area injuries. CONCLUSIONS: Children with pediatric pelvic fractures require careful evaluation for other body-area injuries, as these are most likely to be related to hemorrhage or mortality.     

The profile of level I trauma center directors

BACKGROUND: No data are available regarding the characteristics of the trauma directors of Level I trauma centers. METHODS: Questionnaires were mailed to 102 directors of Level I trauma centers. Data were analyzed in a blinded fashion. RESULTS: Seventy-two directors responded. All were men, with a mean age of 48 +/- 6 years. Fifty-eight percent of directors were fellowship trained. Directorship was assumed 7.3 +/- 6.1 years after training and the average time on the job was 8.6 +/- 6.1 years. Directors work in urban (93%), university-affiliated (67%) institutions that admit 1,000 to 2,000 patients annually (50%). Practice time distribution is as follows: trauma clinical care, 33%; general surgery, 20%; administrative work, 18%; critical care delivery, 17%; and research, 11%. Directors take 6.6 +/- 2.2 night calls per month, with half of them taking in-house call. Eighty-eight percent of directors are involved in research. Seventy-eight percent of directors earn $200,000 to $325,000 per year, with the largest group making $225,000 to $250,000. Salary is derived from clinical revenues (42%) and hospital (37%) or university (20%) support. Compensation is higher in community hospitals and tends to be higher in the Midwest. CONCLUSION: The profile of the trauma director at a Level I trauma center was described. This may be important in trauma career and systems development.
