The AHRQ PSNet Collection comprises an extensive selection of resources relevant to the patient safety community. These resources come in a variety of formats, including literature, research, tools, and Web sites. Resources are identified using the National Library of Medicine’s Medline database, various news and content aggregators, and the expertise of the AHRQ PSNet editorial and technical teams.
The epidemiology of medical error has been intensively investigated in prior studies, with the goal of quantifying the overall burden of preventable harm on a population basis. This study uses econometric techniques to address a related but distinct question: what is the daily risk of a patient safety event for a typical hospitalized patient? The authors arrive at estimates of the daily risk of various safety problems, including adverse drug events, pressure ulcers, and hospital-acquired infections, and also find that the probability of experiencing an adverse event increases with increasing hospital length of stay.
