RadRemind!-an Automated Paging System for Reminding Radiology Residents of Their Roles and Responsibilities.

Tasks which are scheduled at irregular intervals afford greater scheduling flexibility but are also more difficult to remember. Difficulty remembering clinical tasks not only create potential inefficiencies in patient care but were also identified as a source of anxiety among our residents. We implemented RadRemind! an automated system of pager notifications in order to improve patient care and reduce residents' anxiety. RadRemind! utilizes only an external shared APACHE, MySQL, PHP server. A set of CRON jobs activate a PHP script which pulls information from our resident schedule as JSON data. It then identifies the appropriate residents to notify and then sends a cURL request to a web-based paging service to trigger notifications to residents' pagers. Each activation of the script was logged in an SQL database. An anonymous survey assessing multiple aspects of efficacy was sent to residents after 3 months of implementation. Seventeen of 29 residents responded to the survey. Residents reported a mean of 2 successful reminders (defined as responsibilities which had been otherwise forgotten prior to the page notification) in the last month which was found to be statistically significant via one-sample t test (t = 3.3, p < 0.01). Paired t test showed a statistically significant (t = 2.9, p = 0.01) decrease of 2 points in reported anxiety. Repeated measures analysis of variance found a statistically significant variation in reported utility (F(3,16) = 15.9, p < 0.01)) by type of reminder such that reminders for interventional radiology call were found to be more useful than reminders for other tasks. Use of an automated paging system is an effective method of reminding residents of irregularly scheduled responsibilities and is associated with reduced scheduling related anxiety.
