Improving Acute Orthopaedic Admission Note Documentation Standards at a Tertiary Centre Through Proforma Introduction: A Quality Improvement Initiative.

Background Clear, accurate written documentation plays an important role in the handover of medical information, helping to improve care efficiency and avoid medical errors. Both HSE and the Irish National Orthopaedic Models of Care guidelines include key documentation standards for admission notes. Standardised medical admission proforma can help improve documentation standards, but their usage across Irish orthopaedic units is limited to three centres. We evaluated whether an admission proforma improved the documentation standards of acute orthopaedic trauma admission notes within our regional trauma unit. Methods Cycle 1 consisted of a retrospective review of 50 consecutive acute orthopaedic trauma admissions. Exclusion criteria included planned admissions, age <16 years, spinal or pelvic trauma, and 'hip' fractures for whom an existing proforma was in use. Cycle 2 consisted of a prospective review of 50 consecutive acute trauma admissions using the new proforma. Each cycle was scored against a pre-determined checklist incorporating Irish Health Service Executive and Orthopaedic Models of Care documentation standards, with results collated and statistical analysis then performed using Fisher's exact test. Findings Significant improvements in admission note compliance with national documentation were observed. This encompassed multiple domains including clinical identification, e.g., consultant identification (78% to 100% p=0.0005), clinical history, time of injury (72% to 100% p=0.0001), medical history, smoking status (86% to 100% p=0.0001), and patient assessment, vital signs (28% to 70% p=0.0001). Conclusion Improvements in admission note compliance with national documentation standards followed the introduction of a standardised proforma. These findings may encourage the introduction of similar proforma in other units, with potential benefits in patient care.

553 Quality Improvement: The Implementation of Routine Tertiary Trauma Survey in all Trauma Patients Aged Over 60 Years in a Busy District General Hospital

Abstract Introduction Missed injury (MI) in trauma-patients is a widely reported phenomenon, with rates varying from 1.9-39%. Methods exist to reduce the incidence of MI’s such as the tertiary-trauma-survey (TTS). Robust primary and secondary surveys should indeed identify all injuries and facilitate management. However, for trauma patients, there remains an unwanted prevalence of MI. We hypothesized the addition of TTS may reduce the incidence of MI in a District General Hospital (DGH) and reduce associated morbidity and mortality; in particular in those aged &amp;gt;60. Method Patient notes for 18 consecutive trauma admissions in those &amp;gt;60 years were audited for admission demographics, timing and outcome of primary, secondary, and tertiary surveys, and occult injury. The TTS bundle was subsequently implemented in all trauma inpatients &amp;gt;60. Results In the primary round, 11% (n = 2) had evidence of TTS within 36hr of admission, reflective of exceeding the TARN criterion. TTS is now being utilised and we expect to see &amp;gt;98% compliance. Conclusions TTS is now incorporated as routine patient care for all trauma admissions &amp;gt;60. Compliance will be re-audited; aiming to reduce the opportunity for missed injury morbidity.

Frequency and relevance of acute peritraumatic pulmonary thrombus diagnosed by computed tomographic imaging in combat casualties

Posttraumatic pulmonary embolism is historically diagnosed after clinical deterioration within the first week after injury. An increasing prevalence of immediate and asymptomatic pulmonary embolism have been reported in civilian and military trauma, termed hereafter as acute peritraumatic pulmonary thrombus (APPT). The objective of this study was to define the frequency of APPT diagnosed by computed tomographic (CT) imaging in wartime casualties. An additional objective was to identify factors, which may be associated with this radiographic finding A 1-year retrospective cohort analysis conducted using the US and UK Joint Theater Trauma Registries performed to determine the prevalence of and risk factors for the diagnosis of APPT in casualties admitted to Bastion Hospital, Afghanistan. APPT imaging characteristics were collected, and demographics, injury severity and mechanism, and risk factors were included in the analysis. Logistic regression was used to identify factors independently associated with APPT. APPT was found in 66 (9.3%) of 708 consecutive trauma admissions, which received a CT chest with intravenous contrast as part of their initial evaluation. Diagnosis of APPT at the time of injury was made in 23 patients (3.2%), while thrombus was detected in 43 additional patients (6.1%) at the time of reexamination of CT images. Of the APPTs, 47% (n = 31) were central, 38% (n = 25) were segmental, and 15% (n = 10) were subsegmental. Forty-seven percent (n = 31) had bilateral APPT. Logistic regression found presence of deep venous thrombosis on admission (odds ratio, 5.75; 95% confidence interval, 2.44-13.58; p < 0.0001) and traumatic amputation (odds ratio, 2.53; 95% confidence interval, 1.10-5.85; p = 0.030) to be independently associated with APPT. All APPTs were felt to be incidental and likely would not have required interventions such as anticoagulation or vena caval interruption. This report is the first to characterize acute, peritraumatic pulmonary thrombus in combat injured. Nearly 1 in 10 patients with severe wartime injury has findings of pulmonary thrombus on CT imaging, although many instances require repeat examination of initial images to identify the clot. APPT is a phenomenon of severe injury and associated with deep venous thrombosis and lower-extremity traumatic amputation. Additional study is needed to characterize the natural history of peritraumatic pulmonary thrombus and the indications for anticoagulation or vena cava filter devices.

Epidemiology of Acute Transfusions in Major Orthopaedic Trauma

The orthopaedic trauma-related blood product usage is largely unknown. Aim of this study was to describe the epidemiology of early (<24 hours of arrival) blood component use in major orthopaedic trauma. 12-month prospective observational study. John Hunter Hospital, Level 1 Trauma Center, New South Wales, Australia. 64 consecutive trauma admissions identified, who had an orthopaedic injury and required at least 1 unit of packed red blood cells (PRBC) <24 hours of arrival. Epidemiological study. Demographics, orthopaedic injury type, procedure type, injury severity score, timing, place of first unit of transfusion, and blood component volumes were collected. Activation of the massive transfusion protocol was recorded. Primary outcome measures were intensive care unit admission and mortality. From 965 major trauma admissions, 64 had one or more orthopaedic injuries and were transfused <24 hours. Forty-eight percent (31/64) required massive transfusion protocol activation. Average age was 41 ± 21 years, 73% (47/64) men. Eighty-four percent (54/64) required emergent orthopaedic intervention, 41% (22/54) having multiple procedures. Overall mortality was 13% (8/64). Twenty-five percent (16/64) required ≥10 units of PRBC. Average PRBC use was 7.2 ± 6.6 units and fresh frozen plasma use 4.3 ± 5.2 units. Thirty-nine percent (25/64) had a pelvic ring injury or acetabular fracture. Thirty-seven percent (24/64) had at least one femoral shaft fracture. Twenty patients had a total of 23 tibia fractures. Orthopaedic trauma patients consume the majority of the blood products <24 hours among blunt trauma patients. This resource-intensive group requires frequent urgent surgical interventions and intensive care unit admission. Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Does prehospital prolonged extrication (entrapment) place trauma patients at higher risk for venous thromboembolism?

Background The aim of this study was to determine if prolonged immobility and tissue injury from a prehospital entrapment would place patients at higher risk for in-hospital venous thromboembolism (VTE) complications. It was hypothesized that entrapment would increase in-hospital VTE. Methods All consecutive trauma admissions over a 10-year period were retrospectively reviewed. Patients were divided into those who were entrapped according to defined prehospital criteria for entrapment and those who were not entrapped. The complications of deep vein thrombosis and pulmonary embolism were noted. Results There were 15,159 patients admitted between 1999 and 2008. Of these, 1,176 met the criteria for prehospital entrapment. Those patients who met the criteria for entrapment had a significant risk for developing both deep vein thrombosis ( P < .001, χ 2 test) and pulmonary embolism ( P = .005, Fisher's exact test). Multiple logistic regression analysis revealed entrapment to be a significant contributing risk factor to the development of VTE (odds ratio, 1.54; P = .04). Conclusions Patients with prehospital entrapment are at higher risk for VTE. These results mandate aggressive VTE prophylaxis in patients with histories of prehospital entrapment.

Cost analysis of a system of ad hoc theatre sessions for the management of delayed trauma cases.

BackgroundReducing hospital stay optimizes bed capacity. Shortage of operating time can cause some patients to have their treatment and discharge home delayed. Extra operating sessions could help in reducing such a delay. We performed a feasibility study for a simulated model of trauma lists, implemented ad- hoc to reduce time to surgery.Materials and methodsTwo hundred thirty-five consecutive trauma admissions were audited. The time required to deliver surgical treatment was recorded. Patients waiting for their operation more than 48 h from admission were allocated into a simulated system of ad hoc trauma lists, using a realistic decision-making process. The potential to reduce time-to-operation was assessed and the number of saved bed occupancy days was calculated. A cost analysis was also performed.ResultsSurgical treatment was delivered within 48 h in 193 (85%) patients, while 32 (15%) patients waited a mean of 3.8 days (3–7), because of insufficient time. To operate on these patients earlier, additional lists would have cost £38, 703, reducing the time to surgery to 1 day (0–2). This would have saved 86 days of bed occupancy, representing a savings of £17,200. Restricting the use of extra lists to the elderly patients in the cohort would have required only 11 extra lists and reduced waiting from 3 (3–4) to 1 days (0–2), for a cost of £22,407. Elderly patients’ lists would have had space left to treat additional seven younger patients, with a total saving of 51 bed occupancy days, corresponding to £10,200.ConclusionsThe system of ad hoc trauma lists is easy to organize and it appears to impact significantly on patients’ discharge and bed capacity. Direct costs to the health service are contained, as they are partially compensated by the improvement in beds availability.

Cardiac Uncoupling and Heart Rate Variability are Associated With Intracranial Hypertension and Mortality: A Study of 145 Trauma Patients With Continuous Monitoring

A noninvasive tool reflecting intracranial hypertension (ICH) should prompt early invasive monitoring and reduce secondary injury after traumatic brain injury. We hypothesized that integer heart rate variability (HRV) may be associated with rises in intracranial pressure (ICP); changes in HRV may precede changes in ICP; and both increases in ICP and cardiac uncoupling (low HRV) predict mortality. Of 14,330 consecutive trauma admissions, 291 of these patients had an injury requiring intracranial monitoring. Of these patients 145 had simultaneous HRV and ICP monitoring with a Camino monitor. ICP and heart rate (HR) data were matched and divided into 5-minute intervals (N = 117,956, representing 24.4 million HR and ICP data points). In each interval, the median ICP, and SD of HR (HRSD5) were calculated. Cardiac uncoupling was defined as an interval with HRSD5 between 0.3 bpm and 0.6 bpm. Cardiac uncoupling was compared between ICP categories using the Wilcoxon Rank-Sum test, and logistic regression was used to assess the continuous relationship between ICP and risk of uncoupling. Cardiac uncoupling increases as ICP increases (p < 0.001). Uncoupling nearly doubles when comparing acceptable ICP (<20 mm Hg, 11% uncoupled) to ICH (31-50 mm Hg, 18% uncoupled), with uncoupling = 13% in the intermediate group (ICP 21-30 mm Hg). This trend continues at the level of malignant ICH (>50 mm Hg, 22% uncoupled). Cardiac uncoupling increases as ICP increases. Both cardiac uncoupling and ICH predict mortality. Cardiac uncoupling may precede ICH but is not yet an indication for invasive monitoring.

Mild traumatic brain injury does not predict acute postconcussion syndrome

Background:The aetiology of postconcussion syndrome (PCS) following mild traumatic brain injury (mTBI) remains controversial. Identifying acute PCS (within the first 14 days after injury) may optimise initial recovery and rehabilitation,...

Trauma team activation: simplified criteria safely reduces overtriage

Background Our current trauma triage system uses patient and scene variables within a 3-tiered trauma response system. Our purpose was to evaluate the accuracy of the current system and to identify the most reliable variables for trauma triage. Methods This was a retrospective review at a level II trauma center. Multivariate logistic regression was used to identify independent predictors of the need for any urgent emergency department procedure or operative intervention. The current triage system was analyzed and compared with a proposed simplified system. Results There were 1495 consecutive trauma admissions identified, the majority (88%) were blunt mechanism. Urgent emergency department interventions were required in 11%, and 4% required emergent surgery. Logistic regression demonstrated that prehospital Glasgow Coma Score <14 (odds ratio [OR] 9.7), hypotension (OR 3.3), altered respiratory effort (OR 4.6), and penetrating truncal injury (OR 10.8) independently predicted the need for urgent intervention (all P < .01). The current system undertriaged only 1% but overtriaged 51% of patients. A simplified triage system using these 4 variables significantly decreased overtriage and reliably identified patients with severe injury. Conclusions A simplified triage system using only highly predictive variables can safely decrease the high rate of overtriage of trauma patients.

Development of renal failure during the initial 24 h of intensive care unit stay correlates with hospital mortality in trauma patients

Although multiple organ failure is the leading late cause of death, there is controversy about the impact of acute organ dysfunction and failure on trauma survival. Consecutive adult trauma admissions between January 2000 and June 2003, excluding isolated head traumas and burns, were analysed for parameters of organ function during the first 24 h following intensive care unit (ICU) admission using the Sequential Organ Failure Assessment (SOFA) scoring system. A national prospectively collected ICU data registry was used for analysis, including data from 22 ICUs in university and central hospitals in Finland. The study population consisted of 1044 eligible trauma admissions; 32% of the cases were treated at university hospital level, the rest being secondary referral central hospital admissions. The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 15 (SD8), ICU mortality was 5.6% and a further 1.6% of patients died during their post-ICU hospital stay. Forty-five per cent of the patients were categorized as having multiple traumas. In univariate analysis, APACHE II > or = 25 [odds ratio (OR), 35; 95% confidence interval (CI), 18-66] and renal failure (OR, 29.5; 95% CI, 14-63) produced the highest ORs for ICU mortality. In the APACHE II-, sex- and age-adjusted logistic regression model, renal failure was a significant risk factor for both ICU and hospital mortality (OR, 11.8; 95% CI, 3.9-35.4; OR, 8.2; 95% CI, 2.9-23.2, respectively). The development of renal failure during the initial 24 h of ICU stay remained an independent risk factor for mortality in trauma patients requiring intensive care treatment even after adjusting for the APACHE II score, age and sex.

ALCOHOL INTAKE AND THE PATTERN OF TRAUMA IN YOUNG ADULTS AND WORKING AGED PEOPLE ADMITTED AFTER TRAUMA

To investigate the relationship of different patterns of alcohol intake to various types of trauma. We examined the associations of alcohol consumption in a series of 385 consecutive trauma admissions (278 men, 107 women, age range 16-49 years). Patients underwent clinical examinations, structured interviews on the amount and pattern of alcohol intake, and measurements of blood alcohol concentration (BAC). On admission, 51% of the patients had alcohol in their blood. Binge drinking was the predominant (78%) drinking pattern of alcohol intake. Assaults, falls and biking accidents were the most frequent causes of trauma. Dependent alcohol drinking and binge drinking were found to be significantly more common among patients with head trauma than in those with other types of trauma (77% vs 59%, OR=2.38; 95% CI 1.50 to 3.77). The OR for sustaining head injury increased sharply with increasing BAC: 1-99 mg/dl (1.24; 95% CI 0.55-2.01), 100-149 mg/dl 1.64; 95% CI 0.71-3.77), 150-199 mg/dl (3.20; 95% CI 1.57-6.53) and >199 mg/dl (9.23; 95% CI 4.79-17.79). Binge drinking is a major risk factor for head trauma among trauma patients. Assaults, falls and biking accidents are the commonest causes for such injuries. The relative risk for head injury markedly increases with increasing blood alcohol levels. Alcohol control measures should feature in policies aiming at the prevention of trauma-related morbidity and mortality.

Elderly trauma patients with rib fractures are at greater risk of death and pneumonia.

The purpose of this study was to show that elderly patients admitted with rib fractures after blunt trauma have increased mortality. Demographic, injury severity, and outcome data on a cohort of consecutive adult trauma admissions with rib fractures to a tertiary care trauma center from April 1, 1993, to March 31, 2000, were extracted from our trauma registry. Among 4,325 blunt trauma admissions, there were 405 (9.4%) patients with rib fractures; 113 were aged > or = 65. Injuries were severe, with Injury Severity Score (ISS) > or = 16 in 54.8% of cases, a mean hospital stay of 26.8 +/- 43.7 days, and 28.6% of patients requiring mechanical ventilation. Mortality (19.5% vs. 9.3%; p < 0.05), presence of comorbidity (61.1% vs. 8.6%; p < 0.0001), and falls (14.6% vs. 0.7%; p < 0.0001) were significantly higher in patients aged > or = 65 despite significantly lower ISS (p = 0.031), higher Glasgow Coma Scale score (p = 0.0003), and higher Revised Trauma Score (p < 0.0001). After adjusting for severity (i.e., ISS and Revised Trauma Score), comorbidity, and multiple rib fractures, patients aged > or = 65 had five times the odds of dying when compared with those < 65 years old. Despite lower indices of injury severity, even after taking account of comorbidities, mortality was significantly increased in elderly patients admitted to a trauma center with rib fractures.

Day for Night: Should We Staff a Trauma Center like a Nightclub?

Most trauma services throughout the country are staffed on a fixed-call rotational basis. Staff is deployed in a linear fashion when trauma often occurs in a skewed sporadic fashion resulting in large fluctuations in volume, injury severity, and mechanism of injury. Medical error and increased mortality have been associated with certain admission times. We reviewed 8015 consecutive major trauma admissions over a 3-year period. When reviewing aggregate data we found a significant difference in mortality between patients admitted during the day (7:00 AM to 6:59 PM) compared with those admitted at night (7:00 PM to 6:59 AM) (10.1% vs 13.1%, P < 0.01). On further analysis the two populations were found to be significantly different in volume, Injury Severity Score (ISS), and mechanism of injury. More patients were admitted at night and on weekends. They had a higher ISS, higher frequency of penetrating trauma, and a higher likelihood of undergoing operative intervention. Multiple subset analyses were performed stratifying for ISS, time of admission, day of admission, and mechanism of injury using mortality rate as the end point. Six comparisons were performed: 1) morning versus night admission; 2) weekday versus weekend admission; 3) least busy day (Tuesday) versus busiest day (Sunday) admission; 4) weeknight versus weekend night admission; 5) in cases of penetrating trauma, morning versus night admission; and 6) in cases of blunt trauma, morning versus night admission. None of the six comparisons showed a significant difference in mortality. There was no significant difference in ISS-matched mortality related to fixed trauma call staffing.

The role of oral contrast administration immediately prior to the computed tomographic evaluation of the blunt trauma victim

Background: It is unclear whether the administration of oral contrast followed by immediate computerised tomographic (CT) scanning presents a significant risk of aspiration and whether it is useful in the diagnosis of hollow viscus injury. Objective: Determine the number of intestinal perforations diagnosed by oral contrast enhanced CT scans for blunt trauma and identify those who developed aspiration pneumonitis causally related to oral contrast administration. Methods: We analysed a database of consecutive blunt trauma admissions over a 2-year period. The majority received oral contrast immediately prior to CT scanning. We determined the number of intestinal perforations identified by abdominal CT confirmed at laparatomy and the number of cases of aspiration pneumonia. Results: Nine (1%) of the 1173 CT scans identified enteric perforations. Oral contrast enhanced CT scans demonstrated pneumoperitoneum (3), extraluminal contrast extravasation (2), and the presence of free fluid with small bowel wall thickening (8). In this same cohort, eight (0.7%) cases of aspiration pneumonia were diagnosed within 48 h of admission in patients with a mean GCS of 4.25; only one (0.1%) was temporally related to oral contrast administration. In a prospective study, none of the 65 consecutive patients who received oral contrast had witnessed aspiration. Conclusions: Oral contrast administration given immediately prior to CT scanning does not increase the risk of clinically significant aspiration and assists in the detection of enteric perforation.

An economic evaluation of trauma care in a Canadian lead trauma hospital.

The objective was to determine the average cost per quality-adjusted life year (QALY) gained of treating trauma victims at a tertiary trauma hospital and to determine the cost-effectiveness of trauma care at this center. The setting was a tertiary trauma center in the province of Ontario, Canada. The study population consisted of consecutive trauma admissions with ISS > 12 from April, 1994 to April, 1996. The study was of a retrospective cohort design with a cross-sectional survey. The hospital perspective was taken. Costs were determined from a retrospective cohort using a hospital-based case-costing system. Utility estimates for calculation of QALYs gained were obtained using a cross-sectional survey design. Cost-effectiveness was determined by estimating the incremental cost/QALY attributable to treatment at the trauma center. Sensitivity analysis was employed to vary assumptions about the proportion of costs and increased survival. 484 patients with a median age of 39 years and a median ISS of 22 were studied. The average cost per QALY was $1,721, with a maximum value of $3,861. The increase in cost per QALY gained for treatment in a tertiary care center as opposed to a nontrauma center was $4,303, assuming a 20% increase in survival and assuming that the existence of the center increased the cost of care by 50%. The incremental cost/QALY ranged from $191 to $15,492 in the sensitivity analysis varying assumptions about the increased proportion of costs and survival attributable to care at the tertiary trauma center. This is the first economic evaluation of tertiary trauma care which includes both costs as opposed to charges as well as estimates of the QALYs gained. The results suggest that tertiary trauma care is cost-effective and less costly than treatment programs for other disease conditions when the quality-adjusted life years gained are included in the evaluation.

Astereopsis Caused by Traumatic Brain Injury

Impaired depth perception (astereopsis) has been observed in a variety of cerebral pathologies affecting the posterior parietal lobe. In the current study of 93 consecutive head trauma admissions, 24% had complete astereopsis and 41% performed more than 2 SDs below the orthopedic control group mean. Degree of impairment was related to Glascow Coma Scale score, length of posttraumatic amnesia, reduced visuospatial and memory abilities, and the presence of intracranial pathology of the parietal lobes. Impairment was also related to trauma severity in patients without any visualized intracranial pathology, presumably due to diffuse axonal shearing. Clinically meaningful impairment was observed in 25% of this group; 10% had complete astereopsis. Stereoacuity screening requires 1 to 2 minutes. Undetected astereopsis may increase risk for subsequent motor vehicle accidents or falls.

Penetrating cardiac injuries: a population-based study.

Wide variances exist in reports of survival rates after penetrating cardiac injuries because most are hospital-based reports and thus are affected by the local trauma system. The objective of this study was to report population-based, as well as hospital-based, survival rates after penetrating cardiac injury. Retrospective cohort analysis was performed during a 7-year period of 20,181 consecutive trauma admissions to a regional Level I trauma center and 6,492 medical examiner's reports. A meta-analysis was performed comparing survival rates with available population-based reports. There were 212 penetrating cardiac injuries identified, for an incidence of approximately 1 per 100,000 man years and 1 per 210 admissions. The overall survival rate was 19.3% (41 of 212) for the population studied, with survival rates of 9.7% (12 of 123) for gunshot wounds and 32.6% (29 of 89) for stab wounds. Ninety-six of the 212 patients were transported to the trauma center for treatment, resulting in an overall hospital survival rate of 42.7% (41 of 96), with a hospital survival rate of 29.3% (12 of 41) for gunshot wounds and 52.7% (29 of 55) for stab wounds. Review of population-based studies indicates that there has been only a minor improvement in the survival rates for the treatment of penetrating cardiac injuries.

Picture archiving communication system does not decrease the number of radiographs needed to evaluate the trauma patient.

Picture Archiving Communication System (PACS) is a sophisticated software and hardware package that enables clinicians to retrieve, review, and digitally manipulate radiographs from computer workstations throughout the hospital. PACS was instituted at Brooke Army Medical Center in July 1993. Fifty consecutive trauma and 50 consecutive motor vehicle crash (MVC) trauma admissions to an urban trauma center were reviewed before PACS (January 1993) and 18 months after PACS was instituted (January 1995). Patients were compared by the number of radiographs needed during the initial evaluation by type and total. The trauma groups were subdivided by mechanism and also compared. Demographic and physiologic data were collected for each patient. There are no differences in the demographic and physiologic data between groups. For the 50 consecutive trauma admissions, only two areas of statistical difference were found: more chest films were obtained in the MVC PACS group and more pelvis films were obtained in the gunshot wound pre-PACS group. For the 50 consecutive MVC trauma admissions, the PACS group had more chest and total radiographs per patient than the pre-PACS group. More computed tomographic scans of the neck were obtained in the PACS group. PACS did not decrease the number of radiographs needed to adequately and fully evaluate the trauma patient.

Financial outcome of treating trauma in a rural environment.

The financial plight of the urban trauma center is well documented. However, the financial status of the rural trauma center is largely unknown. We hypothesized that our rural trauma center with a high number of blunt trauma patients, a wide spectrum of injury severity, and a large percentage of insured patients would prove to be financially advantageous to the institution. From January 1994 to June 1995, 1,119 consecutive trauma admissions had a complete financial profile compiled including actual costs, reimbursements, and reimbursement ratio (RR = reimbursement/actual costs). Our injury severity profile was very skewed with a preponderance of less severely injured patients (mean Injury Severity Score = 9.6 +/- 7.8). The payor profile of these patients included 49.2% fee-for-service (RR = 1.43), 25.4% diagnosis-related group-based (RR = 0.92), 8.77% per diem (RR = 0.51), and 1.25% capitated (RR = 0.47). Overall, the RR for the trauma unit was 1.11, representing a net profit overall. Cost closely tracked both hospital and intensive-care unit length of stay (R2 = 0.925). Likewise, reimbursement also was reflected in both hospital and intensive-care unit length of stay (R2 = 0.735). We conclude that our rural trauma center, with a favorable payor mix and low injury severity, is financially profitable.
