Comparative StudyUse of the internet and an online personal health record system by US veterans: comparison of Veterans Affairs mental health service users and other veterans nationally.
The Department of Veterans Affairs (VA) operates one of the largest nationwide healthcare systems and is increasing use of internet technology, including development of an online personal health record system called My HealtheVet. This study examined internet use among veterans in general and particularly use of online health information among VA patients and specifically mental health service users. ⋯ Although adoption of My HealtheVet has been slow, the majority of veterans, including mental health service users, use the internet and indicate a willingness to receive and interact with health information online.

An improved model for predicting postoperative nausea and vomiting in ambulatory surgery patients using physician-modifiable risk factors.
Postoperative nausea and vomiting (PONV) is a frequent complication in patients undergoing ambulatory surgery, with an incidence of 20%-65%. A predictive model can be utilized for decision support and feedback for practitioner practice improvement. The goal of this study was to develop a better model to predict the patient's risk for PONV by incorporating both non-modifiable patient characteristics and modifiable practitioner-specific anesthetic practices. ⋯ The EM showed statistically significant improved discrimination over existing models and good calibration. However, the EM should be validated at another institution.
