Clinical Impact and Value of Workstation Single Sign-On

12:00pm - 1:00pm Tuesday, February 12
Orlando - Orange County Convention Center


CHRISTUS Health implemented computer workstation single sign-on (SSO) in 19 hospitals to expedite EHR access. We assessed workflow and financial value of SSO in reducing clinician time at the keyboard logging in. Login duration after SSO implementation was compared to pre-SSO. Dollar value of time saved were calculated for physicians, nurses and ancillary clinicians. Annually 49,057 hours (4088 shifts) of mixed clinician time were liberated from keyboard for the enterprise, a mean of 2584 hours (215 shifts) per facility per year. The annual dollar value of clinician time liberated from keyboard to care for patients was $3.2 million for 19 facilities ($168,474 per hospital).

Learning Objectives: 

  • Identify the overall clinical, operational and financial value proposition of workstation single sign on (SSO)
  • Recognize the nature and magnitude of the impact of SSO on clinician login time by comparing pre-SSO to post-SSO implementation times across 6 hospitals evaluated
  • Recognize the qualitative impact of SSO on clinician satisfaction and how SSO is facilitating adoption of other clinical information technology such as digital documentation
  • Evaluate the results of cost effectiveness and return on investment analyses completed on SSO implementation
  • Analyze the methodology utilized to evaluate and quantify the impact of SSO
