Research: An Evaluation of the Clinical and Financial Value of Work Station Single Sign-on in 19 Hospitals

"Following SSO implementation [for workstations], first-of-shift login was reduced by 5.3 seconds (15.3 percent), and reconnect login duration in the remainder of the shift was reduced by 20.4 seconds (69.9 percent). The total weekly time savings realized by SSO was 943.4 hours (the equivalent of 78.6 12-hour shifts) across 19 hospitals, a mean of 49.7 hours (4.1 shifts) per facility."
