Laboratory Blood Testing In Paediatric Intensive Care Unit Of A University Hospital: Are We Doing It Appropriately?

Retrospective chart review of all children (aged-one month to 16 years) admitted in our paediatric intensive care from June to November 2016 was done to determine the indication of different laboratory tests. LBT indications were defined into: diagnostic/case findings/screening tests to make a diagnosis; haemostatic tests (to monitor function or identify before clinical signs and symptoms) and therapeutic /monitoring tests to get the level of drug directly or getting level of marker as a guide to therapy. Laboratory tests reports which were within normal range more than once were labelled as in-appropriate tests. In total 274 patients, Haemostatic tests were performed for mean of 35.18±56.72 times (range of 0-429), monitoring for mean of 9.38±20 times (range 0-165), and therapeutic tests (3.26±11.25). Most common tests included serum Sodium levels (7.83±12.73), Serum Potassium (8.19±12.80), bicarbonate (7.75±11.9). 13.40±9.11 tests were done on first day and 13.0±8.49/day tests were performed afterwards. Cumulatively 54.31±74.21 tests were performed/ patients out of which 18.5±37.82 were inappropriate.
