Distribution of Laboratory Parameters in Trauma Population.

BACKGROUND

Biochemical laboratory investigations help plan optimum management and communication in short- as well as long-term outcome to trauma victims.

OBJECTIVE

To assess the status of real-time values of biochemical laboratory investigations of different trauma patients and their association with overall mortality.

MATERIALS AND METHODS

Data based on prospective, observational registry of "Towards Improved Trauma Care Outcomes" (TITCO) from four Indian city hospitals. Hemoglobin, hematocrit, random blood sugar, blood urea nitrogen (BUN), and serum creatinine of patients on admission were recorded. Logistic regression was applied with all biochemical investigation as independent variable and overall mortality as dependent variable.

RESULTS

Among 17047 trauma patients, 3456 with available laboratory result details were considered for this study. Overall mortality was 20% (range 14%-21%). For the higher laboratory results, value mortality was 21%-70%, with highest death (70%) for higher hemoglobin patients, followed by hematocrit (44%) and then creatinine (43%). Odds of high hemoglobin compared to normal were 15.20; odds of higher and lower of normal creatinine were 3.80 and 1.65 and for BUN were 2.17 and 1.92, respectively. Gender-wise significant difference was in overall female mortality (29%)% compared males (18%). Similar differences were replicated with results of each laboratory tests.

CONCLUSION

The study ascertained the composite additional explanatory values of laboratory parameters in predicting outcome among injured patients in our population from Indian settings.
