To assess the clinical use of the Dynamic Objective Risk Assessment (DORA) severity of illness score in a site remote from its development.
Prospective chart review.
Tertiary referral pediatric intensive care unit (PICU).
One hundred sixty consecutive admissions involving 621 patient days.
MEASUREMENTS AND MAIN RESULTS:
Pediatric Risk of Mortality (PRISM) scores were collected daily for all PICU patient days. Collection of data was performed by a physician not directly involved in the ordering of vital signs or laboratory data. The daily DORA score was calculated from the previous day's PRISM score and the admission PRISM score according to a previously described formula. The DORA score determines the patient's risk of mortality for the next 24 hrs. Also documented were the tests not ordered for each patient day. The sensitivity and specificity of the DORA score in our patient population were very similar to that previously reported using the previously described 1% cutoff for predicted mortality. We also noted that the tests ordered were related to the physician's perception of the patient's degree of sickness, and were themselves predictive of outcome.
An outcome scoring system created in one group of PICUs can be applied to patients in another PICU remote from where the scoring system was developed with similar ability to predict outcome.
