The Impact of an Emergency Department Toxicology Team in the Management of Acute Intoxication

Abstract

Objective To evaluate the impact of the recently established Emergency Department (ED) Toxicology Team of Queen Mary Hospital (QMH) in the management of acute intoxication. Method A descriptive comparative study with retrospective data collection from all intoxicated and suspected intoxicated patients over two separate half-year periods in 2001 and 2006, before and after the establishment of the ED Toxicology Team in July 2005. Data on reasons of intoxication, drugs and substances involved, ED treatments, patient disposition, length of stay in ED, length of stay in hospital, patient outcome, and 30-day ED re-attendance and hospital re-admission were collected and examined. Results A total of 333 intoxicated patients were included in the study, 171 in 2001 and 162 in 2006. The basic epidemiological data were similar in both groups. There was a marked reduction in hospital admissions from 89.5% to 40.7% (P<0.01) and significant decline in average length of hospital stay from 46.8 hours to 29.2 hours (P<0.05). There was no statistically significant difference in patient outcome, 30-day ED re-attendance and hospital re-admission. Conclusion Our findings showed that the establishment of the ED Toxicology Team in QMH achieved significant reductions in hospital admissions and the length of stay in hospital in the management of patients with acute intoxication without jeopardising patient outcome. The results illustrate that the new model has a beneficial role in reducing cost and alleviating stress on hospital bed availability, therefore it can be recognised as a cost-effective means of management of acute intoxication.
