Maintaining patient throughput on an evolving trauma/emergency surgery service.
BACKGROUND: The case-management team (CMT) has been an effective tool to decrease denied days and improve hospital throughput on a trauma service. With the addition of emergency general surgery (EGS) to our practice, we reviewed the ability of the case management team to absorb EGS patients on the inpatient trauma service while maintaining the improvements initially realized. METHODS: An interdisciplinary CMT was implemented in January 1999. CRNPs were added in August 2003 to address the Accreditation Council for Graduate Medical Education resident work-hour restrictions. "Key communications" for each CMT member are reported three times per week as defined by a hospital-approved policy. Beginning in August 2001, the trauma service was expanded to include EGS patients. Data from the trauma registry, hospital utilization review, and finance office were analyzed before (1998 and 1999) and after (2003 and 2004) the addition of EGS. Tests of proportion were used to evaluate questions of interest. RESULTS: The number of injured patients admitted to the trauma service remained relatively constant during the study periods, ranging from a high of 1,365 in 1999 to a low of 1,116 in 2003. Beginning in 2003, the influx of emergency surgery patients to the service was marked. By 2004, there were 561 emergency surgery admissions, representing more than 30% of the total service admissions. As a result, the total number of service admissions has dramatically increased, reaching 1,833 in CY 2004, a 56% increase from CY 1998 levels. Hospital length of stay data varied from a low of 5.5 days in CY 1999 to a high of 6.9 days in CY 2003. Length of stay appeared to be associated with injury severity (mean Injury Severity Score 11.8 in 1999 and 13.1 in 2003) and case mix, but not associated with denied days. The percent of denied days decreased over the study periods, from 4.6% in 1998 (before the implementation of the CMT) to 0.5% in 2004 (p<0.01). The percent of readmissions also fell significantly over the study periods (4.0% in 1998 to 1.8% in 2004; p<0.01). CONCLUSIONS: The initial improvements in patient throughput noted after the introduction of a CMT in January 1999 have been maintained in recent years despite the addition of an EGS component to the trauma service. Percent denied days and readmissions have continued to decrease. The length of stay for these patients remains, in part, dependent on other factors. The CMT plays an integral role in maintaining the efficiency of a trauma/emergency surgery service.

The evolving role of interventional radiology in trauma care.
BACKGROUND: Although the traditional role of radiology in trauma care has been diagnostic, therapeutic interventional radiology (IR) techniques have now become essential in the management of many injuries. We hypothesized that IR has evolved at our institution over the last decade from a largely diagnostic to a more therapeutic role in the care of the injured patient. METHODS: Demographic information, computed tomographic scans of the chest and abdomen, and angiographic procedures (APs) performed within 48 hours of admission were reviewed in all patients evaluated at a Level I trauma center for the periods 1993 to 1995 and 2000 to 2002. All APs performed with the intent to embolize, stent, or insert a device into a vessel were designated as therapeutic. Analysis by means of chi provided between-group comparisons for questions of interest and the Student's t test was used for comparison of means. RESULTS: A total of 4,750 patients were reviewed, 1,677 from the time period 1993 to 1995 and 3,073 from the period 2000 to 2002. Overall injury severity as measured by the Injury Severity Score (ISS) was similar in both groups (9.6 vs. 9.9, p = not significant). The number of angiograms obtained decreased significantly from 7.1% to 4.0% of all patients (p < 0.01). Concurrently, the fraction of all angiograms that were considered therapeutic rose from 10% to 22% (p < 0.05). The overall number of aortic arch angiograms decreased over time (from 3.6% to 0.9%, p < 0.01), and the percentage of positive examinations increased from 5.0% to 21.4%. In comparison, the number of computed tomographic scans of the chest increased from 1.6% of all patients to 10.8% (p < 0.01). CONCLUSION: Axial imaging studies are being used more frequently to screen trauma patients for injury. Concurrently, diagnostic APs are less frequently performed but are more frequently positive. In addition, IR studies are increasingly focused on therapeutic intervention. IR program development and support is an integral aspect of modern trauma care. These findings have prompted our institution to equip the IR suite to function as an active resuscitation area similar to the trauma bay and intensive care unit.

Integrating emergency general surgery with a trauma service: impact on the care of injured patients.
BACKGROUND: There has been considerable discussion on the national level on the future of trauma surgery as a specialty. One of the leading directions for the field is the integration of emergency general surgery as a wider and more attractive scope of practice. However, there is currently no information on how the addition of an emergency general surgery practice will affect the care of injured patients. We hypothesized that the care of trauma patients would be negatively affected by adding emergency general surgery responsibilities to a trauma service. METHODS: Our institution underwent a system change in August 2001, where an emergency general surgery (ES) practice was added to an established trauma service. The ES practice included emergency department and in-house consultations for all urgent surgical problems except thoracic and vascular diseases. There were no trauma staff changes during the study period. Trauma registry data (demographics, injuries, injury severity, and procedures) and performance improvement data (peer-review judgments for all identified errors, denied days, audit filters, and deaths) were abstracted for two 15-month periods surrounding this system change. Chi-square, Fisher's exact, and t tests provided between-group comparisons. RESULTS: The trauma staff evaluated a total of 5,874 patients during the 30-month study. There were 1,400 (51%) trauma admissions in the pre-ES group and 1,504 (48%) in the post-ES group, of which 1,278 and 1,434, respectively, met severity criteria for report to our statewide database (Pennsylvania Trauma Outcome Study [PTOS]). There were 163 (12.7% of PTOS) deaths in the pre-ES group compared with 171 (11.9% PTOS) deaths in the post-ES group (p = not significant [NS]). There was one death determined to be preventable by the peer review process for the pre-ES group, and none in the post-ES group. Both groups had 10 potentially preventable deaths, with the remaining mortalities being categorized as nonpreventable (p = NS). Unexpected deaths by TRISS methodology were 36 (2.8%) and 41 (2.9%) for the two groups, respectively (p = NS). There was no difference in the number of provider-specific complications between the groups (23, [1.8%] vs. 19 [1.3%], p = NS). The addition of emergency surgery has resulted in an additional average daily workload of 1.3 cases and 1.2 admissions. CONCLUSION: Despite an increase in trauma volume over the study period, the addition of emergency surgery to a trauma service did not affect the care of injured patients. The concept of adding emergency surgery responsibilities to trauma surgeons appears to be a valid way to increase operative experience without compromising care of the injured patient.

Abdominal compartment syndrome in the open abdomen.
BACKGROUND: Multiple methods exist to manage in the intensive care unit the patient with an open abdomen. An increasingly common method is the vacuum packed technique. This method accommodates considerable expansion of intra-abdominal contents and should obviate the potential development of the abdominal compartment syndrome (ACS). Despite this, some patients with these temporary abdominal dressings will go on to develop ACS. For the purpose of this study we have defined this clinical entity as the open abdomen ACS. HYPOTHESIS: Patients with an open abdomen who develop ACS have a poor prognosis. Fluid requirements and resuscitative indices may predict which of these patients will develop open abdomen ACS. METHODS: A retrospective review was performed of patients with trauma who had an open abdomen treated with vacuum packed dressings at our urban level I trauma center. Over 1 year (July 1, 1999-June 30, 2000), 5 patients managed with an open abdomen developed ACS. These patients were compared with 15 consecutive patients with an open abdomen who did not develop clinical ACS during that same period. Fluid resuscitation, base deficit, pH, lactate level, systolic blood pressure, prothrombin time, temperature, peak inspiratory pressure, and PCO(2) were abstracted. The Fisher exact test was used for statistical analysis. RESULTS: In patients managed with an open abdomen, ACS developed between 1.5 and 12 hours (mean [SD], 7.5 [3.9] hours) after placement of the vacuum packed dressing. The base deficit, pH, peak inspiratory pressure, PCO(2,) and lactate level were more abnormal and the crystalloid requirements were significantly higher in the ACS group. The systolic blood pressure, temperature, and prothrombin time did not differ between groups. Three patients with ACS developed a second episode of ACS. Mortality in the ACS group was 3 (60%) of 5 patients vs 1 (7%) of 15 patients in the control group. CONCLUSIONS: Management of the open abdomen with the temporary abdominal closure does not prevent the development of ACS. Mortality is high when ACS occurs in this scenario. Severe physiologic derangement and high crystalloid requirements may predict which patients will develop ACS.
