Clinical impact of advanced trauma life support.

The Advanced Trauma Life Support (ATLS) course sponsored by the American College of Surgeons Committee On Trauma (ACSCOT) presents a standardized method of initial trauma care. This study attempted to measure any changes in morbidity and mortality in trauma patients after the introduction of ATLS training. Over a 3-year period (May 1996 to September 1997-pre-ATLS period; December 1997 to April 1999-post-ATLS period), 63 trauma patients with an Injury Severity Scale (ISS) > or =16 (n = 31, pre-ATLS and n = 32, post-ATLS) were prospectively studied in two community teaching hospitals. There was no significant difference in mortality rate between groups (48% [15 of 31] pre-ATLS vs. 30% [10 of 32] post-ATLS; P = .203, Fisher exact test). Mortality rates within the ISS range of 16 to 25 were 64% (nine of 14 pre-ATLS) versus 29% (five of 17 post-ATLS), and for the ISS 26 to 35 subgroup, 40% (four of 10 pre-ATLS) versus 25% (two of eight post-ATLS), and within the ISS 36 to 75 subgroup, 29% (two of seven pre-ATLS) versus 43% (three of seven post-ATLS). There was a significant difference in mortality during the first 60 minutes after admission: 0.0% post-ATLS versus 24.2% pre-ATLS (P = .002, Fisher exact test (95% confidence interval ranged from 12-45% in the pre-ATLS group and 0-11% in the post-ATLS group). According to the TRISS methodology (a worldwide-accepted mathematical method to calculate chances of survival through logistical regression),ATLS improved outcome from sub-"Major Trauma Outcome Study" (MTOS) standard results (z = -2.9 to a MTOS standard result z = -0.49). Our data demonstrate that introduction of the ATLS program significantly improved trauma patient outcome in the first hour after admission, as well as improvement from sub-MTOS standard to MTOS standard levels.

Advanced trauma life support study: quality of diagnostic and therapeutic procedures.

BACKGROUND: The introduction of the ATLS course in The Netherlands in 1995 provided for an opportunity to compare data of trauma patients between a pre-ATLS and a post-ATLS period. MATERIALS AND METHODS: Over a 3-year period (May 1996 - September 1997 pre ATLS; December 1997-April 1999 post ATLS) 63 trauma patients with an AIS-ISS > or = 16 (n = 31, pre-ATLS and n = 32, post-ATLS) were prospectively studied in two community residency training (ACS Level III) hospitals. All diagnostic and therapeutic procedures were recorded by a video-camera and evaluated by a neutral faculty of six experienced ATLS trained specialists. RESULTS: Ten out of 14 interventions were performed qualitatively better in the post-ATLS group, while also the overall score was highly significantly better (4.2 pre-ATLS and 5.8 post-ATLS, p < 0.0001). CONCLUSION: Using the opinion of an expert team, this study identified a significantly lower number of patients with inadequate management.

Trauma resuscitation time.

Documenting the timing and organisation of trauma resuscitation can be utilised to assess performance standards, and to ensure a high quality of trauma resuscitation procedures. Since there is no European literature available on trauma resuscitation time (TRT) in the emergency room, the aim of this descriptive study is to evaluate TRT in the Netherlands. The introduction of an ATLS-trained prehospital mobile medical team (MMT) in the Nijmegen area initiated the on-site advanced trauma life-support for the prehospital management of trauma patients. We studied TRT in two groups of patients, one with, the other without on-site care by a MMT. In the emergency room the use of videotape recording was chosen to document trauma resuscitation (22 actions) and TRT. A specially flow-chart was used to define the TRT-procedures. We studied 43 patients; 27 without MMT treatment and 16 with MMT treatment. The activities were divided into the ABCDE's of trauma care. Significant more patients of the MMT group were intubated before arrival in the hospital (12/16 (75%) versus 2/27 (2%), P<0.05). Eleven definitive airway management interventions (intubation) and one thoracic drainage in the non-MMT group were demanded by the protocol, but not performed before arrival in the hospital. Sixteen out of 22 actions that were documented were carried out at an earlier stage in the MMT group. There was no significant difference between the resuscitation times; in both groups the recorded median time was approximately 43 min. This prospective analysis demonstrates the timing of resuscitation procedures in a resuscitation room and provides some insight into the timing of ATLS initial assessment.
