This is an important resource and has many diverse tools, collections and resources to offer you.
From the website’s About page https://psnet.ahrq.gov/information:
AHRQ Patient Safety Network (PSNet) is a national web-based resource featuring the latest news and essential resources on patient safety. The site offers weekly updates of patient safety literature, news, tools, and meetings ("Current Issue"), and a vast set of carefully annotated links to important research and other information on patient safety ("The Collection").
As of September 2015, AHRQ PSNet also hosts all previous AHRQ WebM&M (Morbidity and Mortality Rounds on the Web) content, including Cases and Commentaries as well as Perspectives on Safety. We have combined the two sites to streamline the user experience, since all content relates to patient safety. AHRQ WebM&M content will continue to be published monthly and feature expert analysis of medical errors reported anonymously by our readers and interactive learning modules on patient safety ("Spotlight Cases"). CME and CEU credit are available.
Supported by a robust patient safety taxonomy and web architecture, AHRQ PSNet provides powerful searching and browsing capability, as well as the ability for diverse users to customize the site around their interests.
