Teamwork contributes to quality and may also reduce incivility and improve nurse retention. An evaluation of a TeamSTEPPS implementation in an intensive care unit included an assessment of teamwork, retention, and incivility. Teamwork improvement occurred from the initial assessment to 3 months later (U = 650, p = .001). Nurses planning to stay increased from 58% in 2016 to 89% in 2018. There was no change in incivility. The study provides strategies and lessons learned.
