Measuring trauma center injury prevention activity: an assessment and reporting tool.

OBJECTIVE: To develop an assessment and reporting tool for a trauma center's community partnership strategy to deliver injury prevention programs in a large metropolitan area. METHOD: The tool was designed to track prevention activity and serve as a reporting format for the parent health system, county designating agency, and the American College of Surgeons' Trauma Center Verification Process. The tool collected data including trauma center paid and volunteer personnel time, equipment, resource, and financial costs, community group and public agency contributions, number of community members receiving prevention material or presentations, impact on public policy, and print and broadcast media coverage. These measurements were incorporated in a reporting grid format. Six youth injury prevention programs were evaluated over a recent 2-year interval to demonstrate the tool's usefulness. RESULTS: Of six programs, three focused on motor vehicle injuries, one on teen suicide, one on firearm injuries, and one on drug and alcohol abuse. Trauma Center personnel asset allocation included 3% full-time equivalent by the Trauma Medical Director, 30% by the Injury Prevention and Community Outreach Coordinator, and 473 person hours (both work and volunteer) by physicians, nurses, and other personnel. Trauma Center equipment and fixed asset expenses totaled $3,950 and monetary contribution totaled $4,430. Community groups and public agencies contributed 20,400 person hours with estimated in-kind costs exceeding $750,000. Five of the six programs continued during the 2-year period. A gun-lock giveaway program was suspended because of a product recall. A total of over 29,000 youth received prevention material and presentations. Four public policy initiatives and 18 Trauma Center media stories with over 50 mentions and 37 new community partnerships resulted. The reports generated were easily incorporated in the trauma center's reports to local and national organizations and agencies. CONCLUSION: This assessment tool provided a detailed but concise accounting of trauma center injury prevention activity. The reports generated were effective in displaying the center's work.

Inner-city victims of violence and trauma care: the importance of trauma-center discharge and aftercare planning and violence prevention programs.

Inner-city trauma centers often provide care for disproportionately indigent populations who are victims of violence. Many of these victims of violence often return to the trauma center with more violent injuries. Research has shown that a majority of these individuals who return to the trauma center for care are expensive to treat, are uninsured and have significant social problems. Two potential policy approaches are discussed: (1) the use of violence prevention programs to attempt to reduce violence in the immediate community and subsequently reduce the number of victims of violence who are treated in trauma centers and (2) the use of aftercare and discharge models that form an alliance between the trauma center and social service providers in the community. Nontraditional interventions will require the collaboration with hospital departments (emergency medicine, surgery, trauma, social work) and outside agencies, such as the courts and probation and parole. Case management, discharge planning, continuous care treatment teams, and violence intervention models offer positive alternatives to the current method of addressing the multiple problems of victims of violence who frequent the ED.

Barriers to interventions for alcohol problems in trauma centers.

There is clear evidence that trauma-related serious injuries and fatalities can be directly linked to alcohol misuse. Because alcohol is a factor in many motor vehicle crashes (the leading cause of death for persons up to age 49), the National Highway Traffic and Safety Administration has set a high priority on decreasing alcohol-related motor vehicle crash injuries. Research now recognizes that most alcohol-impaired drivers who are injured are binge drinkers, not alcoholics. During the past decade, public health and substance treatment researchers have begun to focus on screening and early intervention in clinical settings as a means of reducing alcohol-related injuries. Trauma centers are uniquely positioned to address this problem because of the high percentage of alcohol-impaired patients admitted after motor vehicle crashes. This article discusses the barriers to implementing alcohol screening and intervention programs in trauma centers from the trauma surgeon's perspective.

Management of adult blunt splenic injuries: comparison between level I and level II trauma centers.

BACKGROUND: The factors important in determining outcome when managing adult blunt splenic injuries continue to be debated. Whether trauma center level designation (Level I versus Level II) affects patient management has not been evaluated. STUDY DESIGN: We conducted a retrospective analysis of prospectively gathered data from the Pennsylvania Trauma Outcome Study database that collected information from 27 statewide trauma centers (Level I [15], Level II [17]). Adult patients (ages > or = 16 years) with blunt splenic injuries (ICD-9-CM 865) were evaluated. Demographic data, injury data, and trauma center level designation were collected, and patient management, length of stay, and mortality were analyzed. RESULTS: There were 2,138 adult patients who suffered blunt splenic injuries during the study period (1998-2000). Patients treated at Level II trauma centers (n = 772) had a higher rate of operative treatment (38.2% versus 30.7%) (p < 0.001), but a shorter mean length of stay (10.1 +/- 0.4 versus 12.0 +/- 0.4 days) (p < 0.01) compared with patients in Level I trauma centers (n = 1,366). The rate of failure of nonoperative treatment was lower at Level II trauma centers (13.0% versus 17.6%) (p < 0.05), but the mortality for patients managed nonoperatively was higher (8.4% versus 4.5%) (p < 0.05). Splenorrhaphy was performed more frequently in Level I trauma centers. CONCLUSIONS: Management differences exist in the treatment of adult blunt splenic injuries between institutions of different trauma center level designation. Multicenter studies should account for this finding in design and implementation.

Pediatric trauma center criteria: an outcomes analysis.

BACKGROUND/PURPOSE: Trauma centers (TC) are certified based on widely accepted criteria. These specific criteria rarely are scrutinized individually. The purpose of this study was to analyze the individual components of a pediatric trauma center for their effect on outcome. METHODS: Members of the National Pediatric Trauma Registry were queried about the following: (1) separate pediatric emergency department (ED), (2) pediatric intensive care unit (PICU), (3) pediatric intensivist as PICU director, (4) pediatric surgeon as TC director, (5) in-house attending surgeon, (6) in-house pediatric emergency physician, (7) 24-hour operating room, (8) 24-hour computed tomography (CT) scan. Outcomes analyzed included mortality, length of stay, time in ED, days in PICU, and disability. Victims were stratified based on age (<7 or > or = 7 years) and severity of injury (ISS < or = 16, 17-35, > or = 36). Results were compared using Student's t test and chi2 analysis. RESULTS: A total of 59 of 74 centers responded, 18 were dropped because of low enrollment (mean, 1.6 patients). Questions 3, 4, 6, and 7 were eliminated because of skewed data. An in-house surgeon reduced the amount of time a mildly injured patient (ISS < or = 16) spent in the ED (210 v434 minutes), as did the separate pediatric ED (333 v592 minutes) and pediatric emergency physicians (344 v 507 minutes) in younger patients (> or = 7 years). An in-house surgeon reduced the morality rate in older (> or = 7) severely injured (ISS > or = 36) patients (46.7% v 56.8%; P < .05 for all). No other differences were significant. CONCLUSIONS: In-house personnel improved efficiency for the less severely injured, and an in-house attending surgeon reduced mortality in the severely injured older patient. None of the other variables were found to have a significant impact on outcome.

The association between trauma system and trauma center components and outcome in a mature regionalized trauma system.

BACKGROUND: Regionalized trauma systems have been shown repeatedly to improve the outcome of seriously injured patients. However, we do not have data regarding which components of these systems have the most impact on outcome and to what degree. The objective of this study was to understand the association between various components that make up a trauma system and outcome. METHODS: Surveys were administered to trauma directors at 59 hospitals in the province of Quebec, Canada. Data from the surveys were then linked with specific outcome variables obtained from a regionalized trauma database. Specific outcomes were assigned to trauma system- and in-hospital-based components after controlling for injury severity. RESULTS: Over 4.8 years, 72,073 patients met inclusion criteria. Components found to affect survival after risk adjustment were prehospital notification (OR, 0.61; 95% CI, 0.39-0.94) and the presence of a performance improvement program in that hospital (OR, 0.44; 95% CI, 0.20-0.94). Increased patient volume was associated with a reduction in risk-adjusted mortality (OR, 0.98; 95% CI, 0.97-0.99). Tertiary trauma centers were also associated with a reduction in risk-adjusted mortality compared with both secondary and primary centers (OR, 0.68; 95% CI, 0.48-0.99). CONCLUSIONS: Improvements in outcome in a regionalized trauma system are secondary to a combination of elements, as well as to the interplay of these elements on each other. Prehospital notification protocols and performance improvement programs appear to be most associated with decreased risk-adjusted odds of death.

Ten-year trend in survival and resource utilization at a level I trauma center.

OBJECTIVE: To determine the impact of increasing trauma center experience over time on survival and resource utilization. METHODS: The authors studied a retrospective cohort at a single level I trauma center over a 10-year period, from 1986 to 1995. Patients included all hospital admissions and emergency department deaths. The main outcome measures were the case-fatality rate adjusted for injury severity, hospital length of stay, and costs. RESULTS: A total of 25,979 patients were admitted or died. The number of patients per year increased, from 2063 in 1986 to 3313 in 1995. The proportion of patients transferred from another institution increased from 16.2% to 34.4%. Although mean length of stay declined by 28.4%, from 9.5 to 6.8 days, costs increased by 16.7%, from $14,174 to $16,547. The use of specific radiologic investigations increased; the frequency of operative procedures either remained unchanged (craniotomy, fracture fixation) or decreased (celiotomy). After adjusting for injury severity and demographic factors, the mortality rate decreased over 10 years. The improvement in survival was confined to patients with an injury severity score > or =16. CONCLUSION: Over a 10-year period, the case-fatality rate declined in patients with severe injuries. Overall acute care costs increased, partially because of the increased use of radiologic investigations. Even in otherwise established trauma centers, increasing cumulative experience results in improved survival rates in the most severely injured patients. These data suggest that experience contributes to a decrease in mortality rate after severe trauma and that developing trauma systems should consider this factor and limit the number of designated centers to maximize cumulative experience at individual centers.

Trauma center maturation: quantification of process and outcome.

BACKGROUND AND OBJECTIVE: The regional trauma system with the trauma center as its center is a model for health care networks. However, trauma center maturation has not been defined in the literature. The authors' hypothesis was that maturation of the trauma center would affect quantitatively both process and patient outcome. MATERIALS AND METHODS: A total of 15,303 trauma patients were admitted from 1987 to 1995. Annual admissions increased from 813 to 2669. Resources were generated as patient volume increased. Time to the operating room, length of stay, and complications were determined. TRISS methodology was used to calculate z scores and w values to compare actual with predicted mortality rates. RESULTS: Time to the operating room for laparotomy decreased from 62+/-73 to 35+/-47 minutes, from 32+/-32 to 20+/-17 minutes in hypotensive patients, and for craniotomy decreased from 88+/-54 to 67+/-49 minutes. The incidence of infectious, airway, neurologic, orthopedic, respiratory, gastrointestinal, and procedure-related complications declined significantly. Z scores and w values increased for penetrating and blunt injuries. Deaths for patients with ISS >15 declined significantly. Hospital length of stay decreased for all ranges of injury severity. CONCLUSIONS: As the trauma center matured, the process of delivering patient care became more efficient. The result was improved survival, fewer complications, and a shorter length of stay.

Relationship between weather and seasonal factors and trauma admission volume at a Level I trauma center.

BACKGROUND: We sought to determine whether trauma patient admission volume to our Level I trauma center was correlated with observable weather or seasonal phenomena. METHODS: Trauma registry data and national weather service data for the period between September 1, 1992, and August 31, 1998, were combined into a common data set containing trauma admission data and weather data for each day. Sequential linear regression models were constructed to determine relationships between variables in the data set. RESULTS: There is a highly significant relationship (p < 0.00001) between maximum daily temperature and trauma admissions (R = 0.22). Rain is associated with a decrease in overall trauma volume. Rain had no effect on the number of admissions because of motor vehicle crash, however. Neither humidity nor snowfall affects trauma admission volume. Trauma admissions are significantly more frequent in July and August, and on Saturdays and Sundays (p < 0.05). Linear regression analysis identified maximum temperature, precipitation, day of week, and month as independent predictors of trauma admission volume (p < 0.001, R = 0.328). CONCLUSION: There is a significant relationship between weather and trauma center activity; temperature and precipitation are independently associated with trauma admission volume at our institution. Statistical models of trauma incidence should consider these phenomena. Evaluation of a larger, population-based data set is needed to confirm these relationships.

The utility of venous lactate to triage injured patients in the trauma center.

BACKGROUND: Field triage criteria for trauma patients results in over-triage rates of 30% to 50% to achieve under-triage rates of 10%. This large number of patients may stress trauma center resources. Elevated arterial lactate (ALAC) levels have been shown to be a marker of serious injury but the need for arterial sampling limits the utility of the determination. The goal of this study was: 1) to determine the correlation between venous lactate (VLAC) and ALAC; 2) to determine whether VLAC could identify those patients with serious injuries; and 3) to compare an elevated VLAC level against standard triage criteria (STC) in their ability to identify major injury. STUDY DESIGN: Arterial and venous samples for blood gas and lactate analyses were obtained in 375 patients within 10 minutes of patient arrival to the trauma center. Arterial and venous samples were drawn within 2 minutes of each other, placed on ice, and analyzed within 10 minutes of sampling. The location of sampling was left to physician discretion. Data collected included injury mechanism, demographics, admission vital signs, emergency department disposition, length of stay, and injury severity scores (ISS). Admission to the ICU, need for emergency operation, length of stay, and death were noted. Emergency medical service staff were queried to determine which standard triage criteria (STC) were fulfilled. RESULTS: The mean ALAC was 3.11 mmol/L (SD 3.45, 95% confidence interval [CI] 2.67 to 3.55) and mean VLAC was 3.43 mmol/L (SD 3.41, 95% CI 2.96 to 3.90). There was no significant difference between ALAC and VLAC. The correlation between ALAC and VLAC was 0.94 (95% CI 0.94 to 0.96, p = 0.0001). An elevated VLAC predicted moderate to severe injury and there was a significant association between an increased lactate and maximum Abbreviated Injury Score (AIS) of 4 and 5 (ANOVA, F = 8.26, p < 0.001). Patients with VLAC > or =2 mmol/L had significantly increased relative risks of ISS > or = 13, death, admission to the ICU, and length of stay > 2 days. In comparison with STC, a VLAC > or = 2 mmol/L decreased undertriage in patients with ISS > or = 13 by one half (11% versus 24%) for patients with ISS > or = 13 and decreased over-triage by 28% (46% versus 64%). These data were most pronounced for patients injured in motor vehicle collisions. CONCLUSIONS: VLAC is an excellent approximation for ALAC. A VLAC > or = 2 mmol/L appears to predict an ISS > or = 13, the need for ICU resources, and prolonged hospital stays. VLAC was significantly better than STC in all patients and was most useful in victims of blunt trauma, especially motor vehicle collisions.

Assessing effectiveness of a mature trauma system: Association of trauma center presence with lower injury mortality rate.

OBJECTIVE: To determine effectiveness of trauma center care in a mature trauma system by comparing motor vehicle crash (MVC) death rates in counties with a trauma center (TC) to those without a trauma center (NTC). METHODS: State data for MVCs occurring in 2003 were analyzed. Fatalities from crashes in counties with a TC were compared with NTC counties. The primary outcome was case-fatality rate and the secondary outcome was crash-fatality rate. Data from 67 Florida counties and 20 TCs were assessed. Covariates such as age, speed, alcohol use, prehospital resources, and rural/urban location were adjusted for in the analysis. RESULTS: The statewide incidence of fatality from MVC in 2003 was 18.6 per 100,000. The overall state case-fatality rate was 2.8% (95% CI = 2.4-3.3). There were 13 TC counties with a mean fatality rate of 17.7 per 100,000 (95% CI = 14.5-20.9) and 54 NTC counties with a mean fatality rate 33.4 per 100,000 (95% CI = 28.8-38.0; p < 0.001). The case-fatality rate was 1.4% (95% CI = 1.1-1.7) in TC counties and 3.2% (95% CI = 2.7-3.7) in NTC counties (p < 0.001). Moreover, crash-fatality rate in TC counties and NTC counties was 1.4% (95% CI = 1.0-1.8) versus 3.3% (95% CI = 2.8-3.7) respectively (p < 0.001). CONCLUSIONS: TC counties had significantly lower MVC death rates than NTC counties. This association was independent of age, alcohol use, speed, rural/urban location, and prehospital resources.

Status of physiatry and physical medicine and rehabilitation departments in adult level I trauma centers.

OBJECTIVE: To determine the involvement of physiatrists and physical medicine and rehabilitation (PM&R) departments in the acute care of patients admitted to level I trauma centers. DESIGN: An 18-question survey. SETTING: Adult, level I trauma center. PARTICIPANTS: Physiatrists, administrative directors, and others involved in rehabilitation in their respective trauma centers. Surveys were mailed to 164 PM&R departments in level I trauma centers. One hundred sixteen responses (70.7%) were received. One hundred five responses (64.0% of total) were used. MAIN OUTCOME MEASURES: The 18-item questionnaire covered topics such as number of staff (based at the trauma center) and consulting physiatrists, number of residents, rehabilitation personnel shortages, participation in multidisciplinary patient care rounds, and relationships between the trauma and rehabilitation services. RESULTS: Eighty-five percent of respondents have at least one full-time or part-time physiatrist based in their PM&R departments. Physiatrists consult in 91% of the responding level I trauma centers. Residents rotate through 52% of responding PM&R departments. Forty-four percent of respondents reported staff shortages, with occupational therapy in greatest demand. Seventy-six percent of PM&R departments participate in multidisciplinary rounds with the trauma service. Eighty-nine percent of PM&R departments stated their relationship with the trauma service was excellent or good. CONCLUSION: Physiatrists and other allied health personnel are integral members of the trauma care team in most level I trauma centers participating in this study. Further expansion should be encouraged to facilitate early and comprehensive rehabilitative care in all level I centers.

Effective trauma center partnerships to address firearm injury: a new paradigm.

BACKGROUND: Firearm violence is the second leading cause of injury-related death. This study examined the use of local trauma centers as lead organizations in their communities to address firearm injury. METHODS: Three trauma centers in cities with populations less than 100,000 were linked with a university-based firearm injury research center. A trauma surgeon director and coordinator partnered with communities, recruited and directed advisory boards, established a local firearm injury surveillance system, and informed communities using community-specific profiles. Primary process and outcome measures included completeness of data, development of community-specific profiles, number of data-driven consumer media pieces, number of meetings to inform policy makers, and an analysis of problems encountered. RESULTS: Local trauma centers in smaller communities implemented a firearm injury surveillance system, produced community-specific injury profiles, and engaged community leaders and policy makers to address firearm injury. Community-specific profiles demonstrated consistent firearm suicide rates (6.58-6.82 per 100,000) but variation in firearm homicide rates (1.08-12.5 per 100,000) across sites. There were 63 data-driven media pieces and 18 forums to inform community leaders and policy makers. Completeness of data elements ranged from 57.1% to 100%. Problems experienced were disconnected data sources, multiple data owners, potential for political fallout, limited trauma center data, skills sets of medical professionals, and sustainability. CONCLUSION: Trauma centers, when provided resources and support, with the model described, can function as lead organizations in partnering with the community to acquire and use community-specific data for local firearm injury prevention.

Improved functional outcome for severely injured children treated at pediatric trauma centers.

BACKGROUND: Controversy exists regarding the impact of pediatric trauma centers (PTC) on survival for injured children. However, functional outcome for children treated at PTC compared with adult trauma centers (ATC) has not been evaluated. METHODS: An analysis of children entered in the Pennsylvania Trauma Outcome Study between 1993 and 1997 was conducted. Patients were stratified according to type of trauma center: PTC; Level I ATC; Level II ATC; or ATC with added qualifications (AQ). Functional outcome at discharge was analyzed. RESULTS: For severely injured children, there was an overall trend toward improved functional outcome at PTC compared with ATC AQ and ATC I, but no difference compared with ATC II. PTC showed improved functional outcome at discharge for head injury compared with ATC AQ and ATC I. CONCLUSION: There is an overall trend toward improved functional outcome at discharge for children treated at PTC compared with those treated at ATC AQ and ATC I. Improved outcome for head injury may be a key factor contributing to improved outcome at PTC.

Relationship between trauma center volume and outcomes.

CONTEXT: The premise underlying regionalization of trauma care is that larger volumes of trauma patients cared for in fewer institutions will lead to improved outcomes. However, whether a relationship exists between institutional volume and trauma outcomes remains unknown. OBJECTIVE: To evaluate the association between trauma center volume and outcomes of trauma patients. DESIGN: Retrospective cohort study. SETTING: Thirty-one academic level I or level II trauma centers across the United States participating in the University Healthsystem Consortium Trauma Benchmarking Study. PATIENTS: Consecutive patients with penetrating abdominal injury (PAI; n = 478) discharged between November 1, 1997, and July 31, 1998, or with multisystem blunt trauma (minimum of head injury and lower-extremity long-bone fractures; n = 541) discharged between June 1 and December 31, 1998. MAIN OUTCOME MEASURES: Inpatient mortality and hospital length of stay (LOS), comparing high-volume (>650 trauma admissions/y) and low-volume (</=650 admissions/y) centers. RESULTS: After multivariate adjustment for patient characteristics and injury severity, the relative odds of death was 0.02 (95% confidence interval [CI], 0.002-0.25) for patients with PAI admitted with shock to high-volume centers compared with low-volume centers. No benefit was evident in patients without shock (P =.50). The adjusted odds of death in patients with multisystem blunt trauma who presented with coma to a high-volume center was 0.49 (95% CI, 0.26-0.93) vs low-volume centers. No benefit was observed in patients without coma (P =.05). Additionally, a shorter LOS was observed in patients with PAI and New Injury Severity Scores of 16 or higher (difference in adjusted mean LOS, 1.6 days [95% CI, -1.5 to 4.7 days]) and in all patients with multisystem blunt trauma admitted to higher-volume centers (difference in adjusted mean LOS, 3.3 days [95% CI, 0.91-5.70 days]). CONCLUSIONS: Our results indicate that a strong association exists between trauma center volume and outcomes, with significant improvements in mortality and LOS when volume exceeds 650 cases per year. These benefits are only evident in patients at high risk for adverse outcomes.

Public hospital-based level I trauma centers: financial survival in the new millennium.

BACKGROUND: The medical benefits of trauma centers have been well documented; studies have reported substantial financial losses attributed to trauma care. This study demonstrates the dependence of Level I trauma centers on Disproportionate Share Hospital (DSH) governmental funds and tax dollars. Furthermore, specific injury groups have greater dependence on these funds. METHODS: Records of 553 trauma patients admitted to a public urban Level I trauma center during a 6-month period were reviewed. Patients were grouped according to blunt, penetrating, and thermal injuries. Data for each group included charges, costs, payments, and the source of reimbursement. Profit and loss margins were compared with and without government funds. RESULTS: With diminished DSH funds and tax dollars, a net loss over $2.1 million was incurred. The greatest disparity originates from Medicaid, self-pay, and prisoner patient groups. Inclusion of government funds provided a positive return of over $600,000. CONCLUSION: The financial stability of urban public Level I trauma centers without additional funding is tenuous because of a high proportion of uninsured and underinsured patients. Government tax dollars and DSH funds are required for their continued solvency.

Psychoactive substance use disorders among seriously injured trauma center patients.

OBJECTIVE: To assess the prevalence of psychoactive substance use disorders (PSUDs) among a large, unselected group of seriously injured trauma center patients, using a standardized diagnostic interview and criteria. DESIGN: Prevalence study. SETTING: A level I regional trauma center. PATIENTS: Trauma center patients fulfilling the following criteria were eligible subjects: aged 18 years or older, admission from injury scene, length of stay of 2 days or longer, and intact cognition. OUTCOME MEASURES: The PSUDs were diagnosed using the Structured Clinical Interview (SCID) for the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition (DSM-III-R) and were categorized as abuse or dependence and past or current (within past 6 months). The SCID results were analyzed with respect to demographic factors, injury type, and blood alcohol concentration and urine toxicology results, using chi2 and logistic regression techniques. RESULTS: Of the 1220 patients approached for study, 1118 (91.6%) consented. More than half (54.2%) had a diagnosis of a PSUD in their lifetime. Approximately 90% of alcohol and other drug use diagnoses were for dependence and more than 62% were current. Overall, 24.1% of patients were currently alcohol dependent (men, 27.7%; women, 14.7%; P<.001), and 17.7% were currently dependent on other drugs (men, 20.2%; women, 11.2%; P<.001). Current alcohol dependence rates were not associated with race; rates of dependence on other drugs were higher among nonwhites and victims classified with intentional injuries. While 54.3% of blood alcohol-positive patients were currently alcohol dependent and 38.7% of patients with positive urine screening test results for drugs other than alcohol and nicotine were currently drug dependent, 11.7% of blood alcohol-negative and 3.9% of drug-negative patients, respectively, had current diagnoses of dependence on psychoactive substances. CONCLUSIONS: A high percentage of seriously injured trauma center patients are at risk of having current PSUDs. Patients with positive toxicology screening test results and/or positive screening questionnaire responses should be referred for formal evaluation and treatment.

Inferior vena caval filter use in U.S. trauma centers: a practitioner survey.

Questionnaires were mailed to 620 U.S. "trauma surgeons" to determine a consensus regarding indications for inferior vena caval (IVC) filter placement; 210 (34%) responded. Eighty-seven percent of respondents practiced in Level I trauma centers; 78% were in urban areas and 75% reported more than 1,000 trauma admissions per year. One-half (52%) of those responding were "trauma directors" at their centers. Filter insertion was done by radiologists at 81% of centers, by trauma surgeons at 34%, by vascular surgeons at 33%, and by general surgeons at 13%. Each month, 60% of trauma centers inserted zero or one filter, whereas 27% inserted two to three filters. Complications per year were reported as one or fewer in 85% of trauma centers. Respondents agreed that "absolute indications" for inserting IVC filters were pulmonary embolism while anticoagulated (93%), deep venous thrombosis present and anticoagulation contraindicated (89%), and free-floating ileofemoral thrombus by venogram (54%) and by duplex imaging (45%). "Relative indications" for placement were deep venous thrombosis by duplex imaging (41%) or by venogram (38%), spinal cord injury (40%), pelvic fractures (39%), multiple lower-extremity fractures (29%), concurrent cancer (19%), prolonged bed rest (14%), and obesity (10%). The permanent nature of the filter affected its rate of application. For example, potential removability would significantly (p < 0.01) increase prophylactic placement from 29 to 53% in the patient with multiple lower-extremity fractures. Only 12% considered sepsis and 10% young age as contraindications to IVC filter insertion. Contraindications and complications were few, yet frequency of use was surprisingly low. Radiologists insert the filter more than twice as often as surgeons.
