Nonoperative management of solid abdominal organ injuries from blunt trauma: impact of neurologic impairment.

The role of nonoperative management of solid abdominal organ injury from blunt trauma in neurologically impaired patients has been questioned. A statewide trauma registry was reviewed from January 1993 through December 1995 for all adult (age >12 years) patients with blunt trauma and an abdominal solid organ injury (kidney, liver, or spleen) of Abbreviated Injury Scale score > or =2. Patients with initial hypotension (systolic blood pressure <90 mm Hg) were excluded. Patients were stratified by Glasgow Coma Score (GCS) into normal (GCS 15), mild to moderate (GCS 8-14), and severe (GCS < or =7) impairment groups. Management was either operative or nonoperative; failure of nonoperative management was defined as requiring laparotomy for intraabdominal injury more than 24 hours after admission. In the 3-year period 2327 patients sustained solid viscus injuries; 1561 of these patients were managed nonoperatively (66 per cent). The nonoperative approach was initiated less frequently in those patients with greater impairment in mental status: GCS 15, 71 per cent; GCS 8 to 14, 62 per cent; and GCS < or =7, 50 per cent. Mortality, hospital length of stay, and intensive care unit days were greater in operatively managed GCS 15 and 8 to 14 groups but were not different on the basis of management in the GCS < or =7 group. Failure of nonoperative management occurred in 94 patients (6%). There was no difference in the nonoperative failure rate between patients with normal mental status and those with mild to moderate or severe head injuries. Nonoperative management of neurologically impaired hemodynamically stable patients with blunt injuries of liver, spleen, or kidney is commonly practiced and is successful in more than 90 per cent of cases. No differences were noted in the rates of delayed laparotomy or survival between normal, mild to moderately head-injured, and severely head-injured patients.

Strategies to improve compliance with evidence-based clinical management guidelines.

BACKGROUND: Clinical management guidelines (CMGs) have been developed to standardize physician practices and ensure safe and cost-effective patient care. In June 1996, evidence-based CMGs were initiated at our urban Level I trauma center. This study compares physician compliance with two such CMGs before (PRE) and after (POST) the institution of continuous surveillance by a clinical resource manager. STUDY DESIGN: For 2 months PRE resource manager surveillance hospital records were reviewed retrospectively for compliance with two CMGs. POST data were collected prospectively for 2 months by the resource manager, who alerted practitioners to deviance from CMGs to justify or document therapy alternatives. The CMGs studied addressed deep venous thrombosis and stress ulcer prophylaxis. "Under" or "over" therapy described that which fell short of or exceeded guidelines. Data were analyzed by chi-square; p < 0.05 defined statistical significance. RESULTS: Compliance with the CMGs was 48% PRE and 74% POST (p=0.001). All noncompliant instances POST (and none PRE) were altered or justified. Deep venous thrombosis and ulcer "over" therapy was significantly higher PRE (19% versus 2%, p=0.003; 49% versus 19%, p=0.001), resulting in $22,760.35 in costs. There was no difference in pulmonary embolism or gastrointestinal bleed rate (1%) PRE to POST. CONCLUSIONS: The use of a clinical resource manager empowered to monitor and coordinate physician behavior improves compliance with CMGs. Further study is warranted to validate resultant outcomes benefit, specifically cost-effectiveness and duration of the need for such a program.

The impact of true partnership between a university Level I trauma center and a community Level II trauma center on patient transfer practices.

OBJECTIVE: To examine the effect of a clinical and administrative partnership with an academic urban Level I trauma center on the patient transfer practices at a suburban/rural Level II center. METHODS: Data for 2 years before affiliation (PRE) abstracted from inpatient charts and the trauma registry were compared with that for 2 years after (POST). The following data were collected: number of, reason for, and destination and demographics of transfers. Chi(2) test and t test analyses were used; p < 0.05 defined significance; data are mean +/- SEM. RESULTS: Transfer rate increased from 4% PRE to 6.9% (p = 0.001) POST with no significant difference in age, Glasgow Coma Scale score, Injury Severity Score, or Revised Trauma Score. Repatriation occurred in 12.8% POST (none PRE). The current Level I facility accepted 1.8% of all transfers PRE and 36.4% POST (p = 0.0001). PRE/POST rates by reason are as follows: pediatric, 14.6%/9.0% (p = 0.04); intensive care unit, 0.4%/1.7% (p = 0.13); complex orthopedic, 100%/0% (p = 0.005); vascular, 50%/0% (p = 0.008); spinal cord injury, 100%/100%; and ophthalmologic, 0%/100% (p = 0.005). CONCLUSIONS: In this experience of Level I/II partnership (1) transfer patterns were altered, (2) select patient cohort transfers decreased (pediatric, complex orthopedic, vascular), whereas others increased (aortic work-up), and (3) repatriation rates were low.

The importance of the command-physician in trauma resuscitation.

OBJECTIVE: Definitive trauma team leadership, although difficult to measure, has been shown to improve trauma resuscitation performance. The purpose of this study was to evaluate the effect of an identified command-physician on resuscitation performance. In addition, the leadership capability of four physician combinations functioning as command-physician was studied. DESIGN: Retrospective review. METHODS: Videotapes of trauma resuscitations performed at a Level I trauma center over a 25-month period were reviewed. The presence of an identified command-physician was determined by multidisciplinary consensus. Resuscitation performance was measured by compliance with three objective criteria: primary survey, secondary survey, and definitive plan; and two subjective criteria: orderliness, and adherence to Advanced Trauma Life Support protocol. Performance was then analyzed (1) as a function of the presence or absence of a command-physician, and (2) between four identified physician combinations: AF (attending surgeon + trauma fellow); F (trauma fellow); ASR (attending surgeon + senior surgical resident); SR (senior surgical resident). Chi square and the Mann-Whitney U tests were applied. RESULTS: A total of 425 trauma resuscitations were reviewed. A command-physician was identified (CP[Pos]) in 365 resuscitations (85.7%); no command-physician was identified (CP[NEG]) in 60 (14.3%). Compliance with completion of secondary survey (81.4%) and formulation of a definitive plan (89.6%) was significantly higher in the CP(POS) group. Subjective scores for orderliness and adherence to Advanced Trauma Life Support protocol were significantly higher in the CP(POS) group. In the CP(POS) resuscitations, formulation of a definitive plan was lower in SR when compared with the other three physician combinations. CONCLUSIONS: An identified command-physician enhances trauma resuscitation performance. Completion of the primary and secondary survey is not affected by the physician combination. Prompt formulation of a definitive plan is facilitated by the active involvement of an attending traumatologist or a properly mentored trauma fellow.

Laparoscopic transdiaphragmatic diagnostic pericardial window in the hemodynamically stable patient with penetrating chest trauma. A brief report.

We report two cases of laparoscopically performed transdiaphragmatic diagnostic pericardial window following diagnostic laparoscopy for a penetrating wound to the central anterior thorax below the sixth intercostal space. In the hemodynamically stable patient, this approach permits evaluation of the diaphragm, abdominal viscera, and pericardial space using a single, minimally invasive surgical technique.

Barrier precautions in trauma resuscitation: real-time analysis utilizing videotape review.

Blood-borne pathogens threaten all individuals involved in emergency health care. Despite recommendations by the Centers for Disease Control and the American College of Emergency Physicians, documented compliance with universal precautions in trauma resuscitation has been poor. The purpose of this study was to determine the factors that predispose to noncompliance with barrier precautions at a level I trauma center. Videotapes of trauma resuscitations performed during 1 month (n = 66) were reviewed. Full compliance with barrier precautions was documented in 89.1% of health care workers. Of the noncompliant health care workers, 50.7% were emergency department personnel and 47.8% were first responders to the trauma resuscitation area. Barrier precaution compliance improved from 62.5% to 91.8% with prenotification of patient arrival. Immediate access to barrier equipment is essential for all potential in-hospital first responders. Prehospital communication systems should be optimized to ensure prenotification.

Impact of minimal injuries on a level I trauma center.

Overtriage (i.e.; transport of patients with minimal injuries to a trauma center) has been accepted as necessary to avoid missing clinically significant injuries. We reviewed our experience with 344 patients (ISS less than or equal to 4) who were admitted to a level I trauma center during a 2-year period. The trauma team was activated for 209 patients (TA), and emergency department referrals accounted for 135 (ED). One hundred seventy-three patients (TA = 64%, ED = 36%) met American College of Surgeons' Committee on Trauma (ACSCOT) field triage criteria (FTC). Mechanism of injury, especially ejection from a motor vehicle, was the most frequently utilized FTC indicator. We found no differences between the TA and ED groups relative to Trauma Score, Glasgow Coma Scale score, Injury Severity Score, length of stay, or ICU days. Mean total costs were higher for the TA group than for the ED group. The TA group had a higher nursing acuity level than the ED group. Compliance with FTC yields an inherent overtriage of minimally injured patients; however, noncompliance with FTC compounds the overtriage rate. Failure to comply with FTC is costly, labor intensive, and may represent misuse of the trauma system. We propose continual re-education of prehospital personnel, increased responsibility of all hospitals in the trauma center catchment area, and protocols for "downstaging" trauma resuscitation in minimally injured patients.

Maternal predictors of fetal demise in trauma during pregnancy.

Trauma complicates 6 to 7 per cent of all pregnancies, but fetal demise secondary to maternal trauma occurs much less frequently. This study was done to analyze the incidence of fetal demise as a function of 21 maternal characteristics determined within the first 24 hours after trauma. Nine instances of fetal demise were identified from 73 pregnant patients with trauma admitted to four Level I trauma centers from a combined data base of 30,000 patients. Maternal factors examined by logistic regression were Injury Severity Score (ISS), Trauma Score (TS), Abbreviated Injury Scale (AIS), fluid requirements in the initial 24 hours, systolic blood pressure (SBP), heart rate (HR), hemoglobin, hematocrit and arterial blood gas analysis. Fetal demise was found to be associated with increasing ISS, increasing face and abdominal AIS, increasing fluid requirements, maternal acidosis and maternal hypoxia. Standard maternal laboratory and physiologic parameters, such as hemoglobin and hematocrit, oxygen and hemoglobin saturation, partial pressure of carbon dioxide, SBP and HR were not predictive. The TS was also found to be nonpredictive.
