Aim & Objectives: To study the validity of PELOD score for predicting outcome among PICU patients. Correlation of PELOD score with various outcomes of PICU patients and incidence of various etiologies in PICU.
Material & Methods: A prospective observational study was done in the PICU of Rohilkhand Medical College & Hospital from 1 November to 2016 to 31 october 2017. All patients admitted in PICU during study period fulfilling the specified inclusion criteria after taking consent were assesed for eligibility. After initial evaluation, physical examination and investigations pertaining to PELOD Scoring was done at the time of admission, at 24 hours and on day 4 of admission in addition to standard management of the patient. For the PELOD score, six organ systems:-neurologic, cardiovascular, hepatic, renal, respiratory and hematologic were considered, each with upto 3 variables (total 12 variables). Each variable is assigned points as 0,1,10 and 20 based on the level of severity. Those patients who survived till 96 hours in PICU, were then followed till they were shifted out from PICU or expired after 96 hours in the PICU. Their outcome was defined as Survived and Expired.
Results: There were total 51 patients admitted during the study period. Maximum number of patients were of septicemia. In our Study we found that as the number of organ dysfunction increases, PELOD score also increases. This correlates with the increase in mortality which corresponds to the increase in PELOD score. The mean PELOD score of expired patients was significantly high at time of admission, 17.9, which decreased slightly to 15.5 at 24 hour and which further increased to significantly high level of 26.0 on day 4.
Conclusion: PELOD score has been found to have a direct relation with mortality among patients admitted in PICUs as with increase of PELOD score, chances of mortality are proportionately increased. The PELOD score were calculated at time of admission in PICU and subsequently to estimate the severity of the organ dysfunction and to predict mortality. The change in PELOD score differed in survivors and expired patients and a worsening (increase) in PELOD score was a strong prognosticator of death.
