    Abstract:
    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.
