Impact of Single Sign-on Adoption in an Assessment Triage Unit: A Hospital's Journey to Higher Efficiency.

BACKGROUND: Clinician time is a valuable and costly resource. In an age where computer and clinical application usage is increasing, the need for providers to remember multiple usernames and passwords is increasingly inefficient. Further complexity is added to clinical workflows if clinicians must log into smart devices frequently without a simple solution for access and data security. OBJECTIVE: The purpose of this study was to measure the average time required and time savings when taking vital sign measurements using the Single Sign-On (SSO) (badge scan and go) on the electronic medical record-connected vital sign monitors versus using 2-factor authentication (entry of username and password). In addition, user satisfaction, system usability, workflow preference, and efficacy of the deployment of Network Connectivity Engine, that is, the host middleware for SSO, were evaluated through surveys. METHODS: A preimplementation and postimplementation study was performed in the unit piloting the initiative before hospital-wide deployment. Clinician usability and workflow preference surveys were conducted postimplementation. RESULTS: Analysis showed significance in time savings by adopting SSO. CONCLUSION: SSO had a positive impact on staff efficiency and was the preferred method versus the 2-factor log-in.
