P. Danne et al., THE MAJOR TRAUMA MANAGEMENT STUDY - AN ANALYSIS OF THE EFFICACY OF CURRENT TRAUMA CARE, Australian and New Zealand journal of surgery, 68(1), 1998, pp. 50-57
Background: An audit of the management and outcome of major trauma pat
ients was carried out to determine ways in which the system of care ma
y be improved. Methods: The Major Trauma Management Study (MTMS) colle
cted data prospectively on all consecutively admitted major trauma pat
ients at eight major hospitals during a 12-month period. Outcome was s
tudied using trauma and injury severity score (TRISS) and a severity c
haracterization of trauma (ASCOT) analyses, as well as a preventable o
utcome analysis, which looked at survivors with complications or with
a Glasgow Coma Score < 15 on discharge from hospital, as well as study
ing deaths. Results: The group of 859 patients was more severely injur
ed than most described previously, with a mortality of 14.8% and a mea
n injury severity score of 19.8. Formal ASCOT; analysis indicated 2.25
% fewer survivors than would be predicted by Major Trauma Outcome Stud
y norms. Extrapolating the TRISS and ASCOT process ro include those pa
tients with missing data, and then comparing groups of matched severit
y with the norms, gave no statistically different outcome in the MTMS
group of patients. Preventable outcome analysis revealed rates of prev
entable and potentially preventable (P/PP) outcomes of 32% among death
s and 8% among survivors. The types of management deficiencies respons
ible for P/PP outcomes are identified. Conclusions: The points of defi
ciency in a system of care have been identified, and the development o
f an integrated trauma system in Victoria, based upon these facts, is
recommended, Children, the elderly, patients with head injuries and pa
tients bring transferred between hospitals would benefit from improvem
ents to the system of care. The calculation of efficacy rate (0.95 for
the MTMS patients) is recommended to accurately assess the system of
care. Preventable Outcome Analysis is more relevant to auditing a syst
em of trauma care in detail, than is ASCOT or TRISS. The MTMS has refi
ned and defined the process so that it is reproducible in further comp
arative studies.
