Correlation of PeradeniyaOrganophosphorus Poisoning Scale (POP) and outcome of Organophosphorus poisoning

Abstract

Introduction: Organophosphorus poisoning is one of the common causesfor the intensive care admission in the developing countries.This study was conducted to assess the correlation between Peradeniya Organophosphorus Poisoning (POP) scale and the outcomes in poisoningin a tertiary care hospital in Eastern Nepal.

Objective: To assess the severity and outcome of OP compound poisoning with the correlation of POP score.

Methodology: This was a prospective observational study conducted over 6 months in the intensive care unit at tertiary care hospital in the eastern part of Nepal. The study includedall OP poisoning patients presenting in the emergency department and finally admitted to intensive care unit who fulfilled the inclusion criteria.Correlation was made between POP scores and outcomes in terms of intensive care unit(ICU) stay, need of ventilation and mortality was assessed.

Result: Fifty patients with OP poisoning wereincluded in the study. Suicide attempt was the most common reason for poisoning. The incidence of poisoning was more common among males(72%)and significant majority were aged younger than 35 years (84%). On admission, the number of patients in mild, moderate and severepoisoning group were 52%, 30% and 18% respectively. Rates for ICU stay, respiratory failure requiring ventilator and mortality was significantly (p<0.001) higher in severe POP scale.

Conclusion: The POP scale is a useful clinical assessment tool to assess and categorize patients with OP poisoning according to severity and in predicting their clinical outcomes.
