Assessing the Effect of a Medical Toxicologist in the Care of Rattlesnake-envenomated Patients.

Abstract

Rattlesnake envenomation is an important problem in the United States, and the management of these envenomations can be complex. Despite these complexities, however, the majority of such cases are managed without the involvement of a medical toxicologist. The primary objective of this study was to evaluate the impact of a medical toxicology service (MTS) on the length of stay (LOS) of such patients. The authors conducted a retrospective study at six centers in California. Patients were included if they were admitted in the 2 years before the establishment of a MTS (pre-MTS) or in the 2 years after the creation of a MTS (post-MTS). A total of 300 subjects were included (169 pre-MTS, 131 post MTS). Baseline characteristics between the pre-MTS and post-MTS groups were very similar. The creation of a MTS was associated with a significant reduction in the mean (95% confidence interval) LOS (69.5 [59.1-79.9] hours vs. 48.1 [41.4-54.8] hours). This reduced LOS was not associated with any statistically significant change in readmission rates. Rattlesnake bite patients treated by a medical toxicologist have a significantly reduced LOS compared to those without direct involvement of a medical toxicologist.
