The ASRA TIMEOUT app provides a quick and easy way to execute a pre-procedure timeout. Timeouts have repeatedly been shown to reduce human error prior to performing complex tasks. In regional anesthesia, it is imperative that we perform the correct block on the correct limb for the correct patient every time. The app is based on the 2014 ASRA publication, A Checklist for Performing Regional Nerve Blocks, and was built in collaboration with ASRA to stay consistent with the evidence-based checklist described in that publication. The ASRA TIMEOUT app checklist provides in-line app switching to the ASRA Coags app when the verification of patient anticoagulant status needs to be checked off. The ASRA Coags app allows the user to verify the appropriateness of the patient’s anticoagulation status based on the most recent published ASRA guidelines on regional anesthesia for patients on anticoagulant and antithrombotic medication. In addition, the user has access to the full PDF publication from Regional Anesthesia and Pain Medicine built right into the app. Project developed at Vanderbilt University Medical Center.
