Effect of Organophasphate poisoning among patients reporting at a tertiary healthcare facility of Sindh Pakistan

A retrospective comparison of the burden of organophosphate poisoning to an Intensive Care Unit in Soweto over two separate periods

Introduction

Organophosphate poisoning (OPP) is a major health-care burden in South Africa. Recently, we have observed that patients admitted to our Intensive Care Unit (ICU) with OPP have followed a more complicated course in comparison to previous years.

Objectives

To describe the differences in the clinical course and costs of patients with OPP between two time periods, namely 2012 and 2017.

Methods

Retrospective comparison of patients admitted to the Intensive Care Unit (ICU) of Chris Hani Baragwanath Academic Hospital between January 2012 to December 2012 and January 2017 to December 2017.

Results

Forty-one patients were found in the database. Patients from our 2017 cohort showed a significantly longer total median (IQR) length of stay 8 (4–17) days vs. 2 (2–3) days, p = 0.000, duration of antidote therapy 5 (3−10) days vs. 2 (2–3) days, p = 0.004 and duration of ventilation 4 (2−11) days vs 1 (1–2) day, p = 0.003. Patients presenting in 2017 were more likely to be admitted to ICU, odds ratio 5.6 (CI 1.2–26). There was a 31- fold increase in ICU costs between 2012 and 2017.

Conclusion

Based on our experience, the clinical course of OPP requiring ICU admission has evolved into a condition with a longer length of stay, duration of antidote therapy, ventilatory support, increased risk of complications and additional costs.

Epidemiological, Poisoning Characteristics and Treatment Outcomes of Patients Admitted to the National Poisoning Control Centre at Karachi, Pakistan: A Six Month Analysis

INTRODUCTION

 Any substance if taken in enough quantity can be defined as a poison provided it causes physiological or anatomical harm. It can range from food products to therapeutic medications to toxins and chemicals. Animals, plants, and insects also produce toxins, which are poisonous. While any route of ingestion is dangerous, most poisons are either taken by mouth or inhaled. Rarely intravenous access as in the case of heroin/opoids overdose is seen as well. Poisoning whether deliberate or otherwise is a growing problem of the modern world. Young people are disproportionally affected by it. Mostly household products such as insecticides, bleach, acid, etc. are used. Harmful ingestion of prescription meds, recreational drugs, psychiatric medicines, and opoids has been on the rise in recent times. This is one of the major sources of poisoning these days. Data with respect to Sindh and Pakistan is scarce. As the largest referral center in the country, Jinnah Postgraduate Medical Centre sees its fair share of poisoning cases. Here we evaluate the trends and increasing burden of poisoning cases seen at this center.

AIMS

To evaluate the epidemiological, poisoning characteristics and treatment outcomes of patients admitted to the National Poisoning Control Centre (NPCC) at Karachi, Pakistan.

MATERIALS AND METHODS

 This is a retrospective study, held from July 1^st to December 31^st 2018. Data were recorded from all patients admitted to the NPCC after complete medico-legal work up.

RESULTS

 A total of 2546 patients were inducted into the study. The mean age of presentation was 26.57 ± 11.82 years. Nearly 80% of patients were aged 40 years or younger. Both genders were equally affected and most cases were referred from within the city. Organophosphates (OPs) were the most frequent (46.11%) cause of poisoning seen. Overall mortality was 3.61%.

CONCLUSION

 The burden of poisoning cases has risen sharply. Mostly young adults and teenagers are affected without gender bias. Mortality is high considering the young population involved.
