Toxicology Training Unit in Emergency Department Reduces Admission to other Specialties and Hospital Length of Stay

Abstract

Objective To evaluate the outcome of intoxicated patients presented to Accident and Emergency Department (AED) in Hong Kong with Toxicology Training Unit accreditation and AED without toxicology team. Method A retrospective observational study with data collection from all intoxicated cases reported through Pre-hospital Activated Charcoal Programme, a protocol driven poisoning reporting system, from 1/7/2011 to 30/6/2013 (2 years). Data on basic demographic data (e.g. sex, age), receiving AED, admission rate to other specialty, length of stay in hospital exclude psychiatry ward admission and clinical outcome were collected and analysed. Five AEDs with Toxicology Training Unit (study group) and 7 AEDs without toxicology team (control group) were included. Results A total of 329 intoxicated cases were included in this study. The basic epidemiological data were similar in both groups. There was a significantly lower in hospital admissions in study group (16.9%) than in control group (69.3%; p<0.001) and significant shorter median of hospital stay of 22.1 hours (interquartile range [IQR] 12.8-43.5 hours) in study group compare to 42.7 hours (IQR 20.4-76.1 hours) in control group (p<0.001). Conclusion Our findings show that the establishment of the toxicology training unit can achieve significant reduction in admissions to other specialty and the length of stay in hospital in the management of patients with acute intoxication.
