Background. Accurate data are needed to evaluate outcomes; therapeutics, an
d quality of care. This study assesses the accuracy of administrative datab
ases in recording. information about trauma patients.
Methods. Patients with thoracic aorta injury were identified with a stare t
rauma registry, and the medical records were reviewed. Data collected were
compared to administrative data on patients with thoracic aorta injuries, a
t the same hospitals in the same ti,ne period.
Results. Fifteen patients (16.3 %) with thoracic aorta injury were not reco
rded in the administrative database, and 23 patients (18.7%) were misdiagno
sed. Ninety-one patients were found in both data sources. The administrativ
e database significantly (P < .05) underrecorded abdominal injuries (50 vs
35), orthopedic injuries (117 vs 75), and chest injuries (77 vs 48). The nu
mber of aortigrams (78 vs 8), type Of operative procedures ( use of graft;
70 vs 30), use of bypass (35 us 16), and complications (77 vs 33) were unde
rreported (P < .05). The Injury Severity Score was underestimated by the ad
ministrative database (38.65 +/- 12.41 vs 25.66 +/- 9.53; P < .05).
Conclusions. Administrative data lack accuracy In thp recording of associat
ed injury, injury severity, diagnostic, and procedural data. Whether these
data should be used to evaluate treatment or quality of care in trauma is q
uestionable.
