ABSTRACT
PURPOSE: Timely recognition of critical patients by emergency center triage is an ongoing challenge. Peripheral tissue oxygen saturation (StO2) measurement has been used to monitor shock patients' responses to resuscitation. Interest has developed in evaluating StO2 as a triage tool, but limited studies have addressed critically ill patients. MATERIAL AND METHODS: This is a single-center, retrospective study of 158 emergent cancer patients with hypotension and/or modified systemic inflammatory response syndrome who underwent StO2 spot measurement at triage. RESULTS: Of the 57 patients with StO2 less than 70%, 17 went to the intensive care unit (ICU), whereas only 14 of the 101 patients with StO2 of 70% to 89% (P = .01) went to the ICU. There was no significant difference in non-ICU hospital admission or mortality between the 2 groups. The odds ratio of ICU admission for patients with StO2 less than 70% relative to those with StO2 of 70% to 89% was 2.64 (95% confidence interval, 1.18-5.87) and 2.87 (95% confidence interval, 1.23-6.66) when adjusted for mean arterial pressure, pulse, and temperature. CONCLUSIONS: In this patient population, an StO2 less than 70% significantly increased the risk of ICU admission. Tissue oxygen saturation at triage identifies critical patients who may not be recognized by vital signs alone. Tissue oxygen saturation measurement could help providers make earlier decisions regarding hospital resource allocation.

Flexible gastrointestinal endoscopy is a valuable diagnostic and therapeutic tool for the care of patients with gastrointestinal and pancreaticobiliary disorders. Compliance with accepted guidelines for the reprocessing of gastrointestinal endoscopes between patients is critical to the safety and success of their use. When these guidelines are followed, pathogen transmission can be effectively prevented. Increased efforts and resources should be directed to improve compliance with these guidelines. Further research in the area of gastrointestinal endoscope reprocessing should be encouraged. The organizations that endorsed this guideline are committed to assisting the FDA and manufacturers in addressing critical infection control issues in gastrointestinal device reprocessing.
