"WISER" intervention to reduce healthcare worker burnout - 1 year follow up.

Objective: Test sustainability of Web-based Implementation for the Science of Enhancing Resilience (WISER) intervention efficacy in reducing healthcare worker (HCW) emotional exhaustion (EE), a key component of burnout.

Design: One-year follow-up of WISER RCT using two cohorts (one waitlist control with shortened intervention period) of HCWs of four NICUs each, to improve HCW well-being (primary outcome: EE).

Results: In Cohorts 1 and 2, 194 and 312 WISER initiators were identified by 1-year, and 99 and 80 completed 1-year follow-up, respectively. Combined cohort results showed that relative to baseline, at 1-year WISER decreased EE (-7.07 (95%CI: -10.22, -3.92), p < 0.001), depression (-4.49 (-6.81, -2.16), p = <0.001), and improved work-life integration (6.08 (4.25, 7.90), p = <0.001). EE continued to decline between 6-month and 1-year follow-up (p = 0.022). The percentage of HCWs reporting concerning outcomes was significantly decreased for EE (-10.9% (95%CI: -17.9%, -4.9%); p < 0.001), and secondary outcomes depression and work-life integration.

Conclusion: WISER improves HCW well-being for at least 1 year.
