Hyperbaric oxygen and dental extractions in irradiated patients: short- and long-term outcomes.

Purpose: Mandibular osteoradionecrosis (ORN) can occur in patients post-radiation therapy. This study assessed the incidence of ORN in the setting of adjunctive hyperbaric oxygen therapy (HBO2) and sought to identify risk factors that may predispose to its development.

Methods: A retrospective chart review was completed on patients with a history of radiation therapy to the head and neck who underwent HBO2 prior to and immediately following dental extractions between January 1, 1995, and December 31, 2005, in the hyperbaric medicine unit.

Physicians' ability to predict hospital length of stay for patients admitted to the hospital from the emergency department.

Accurate predictions of patient length of stay (LOS) in the hospital can effectively manage hospital resources and increase efficiency of patient care. A study was done to assess emergency medicine physicians' ability of predicting the LOS of patients who enter the hospital through the ER. Results indicate that EM physicians are relatively accurate with their pediatric patients than any other age groups.
