Abstract

Organophosphate (OP) poisoning is a serious public health problem in underdeveloped nations. Many cases of severe poisoning and more than 220,000 deaths are recorded every year. Early detection and treatment can save lives because OP poisoning has a significant fatality rate. The new Poisoning Mortality Score (PMS) has been developed for clinical decision-making and therapeutic guidance in patients with acute poisoning.

This is a retrospective study that included 236 patients with acute OP poisoning who got admitted to a tertiary care hospital over two years after obtaining permission from the institutional ethical committee. The PMS, Sequential Organ Failure Assessment (SOFA), and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were calculated based on patient details.

The results showed that the mean age of patients was 32.8 ± 13.4 years; 50.8% were men and 49.2% were women. Out of 236 patients, 214 got discharged and 22 died. The mean ± SD of PMS, SOFA score, and APACHE II scores among the discharged patients were 51±7, 1 ± 2, and 5 ± 5, respectively, and those among the expired patients were 70 ± 12, 7 ± 3, and 28 ± 9, respectively. The best cut-off points for predicting mortality in acute OP poisoning patients for PMS, SOFA score, and APACHE II scores were >65, >3, and >15 with sensitivities of 77.27%, 95.45%, and 95.45%, specificities of 96.26%, 91.59%, and 95.79%, and areas under the receiver operating characteristic curve of 0.917, 0.970, and 0.984, respectively.

The study showed that the new PMS is significantly associated with the prediction of mortality in acute OP poisoning in comparison with SOFA and APACHE II scores.
