Objectives: The intensive care unit (ICU) Liberation "ABCDEF" Bundle improves outcomes in critically ill adults. We aimed to identify common barriers to Pediatric ICU Liberation Bundle element implementation, to describe differences in barrier perception by ICU staff role, and to describe changes in reported barriers over time. Study Design: A 91-item survey was developed based on existing literature, iteratively revised, and tested by the PICU Liberation Committee at Seattle Children's Hospital, a tertiary free-standing academic children's hospital. Voluntary surveys were administered electronically to all ICU staff twice over 4-week periods in 2017 and 2020. Survey Respondents: 119 (2017) and 163 (2020) pediatric and cardiac ICU staff, including nurses (n = 142, 50%), respiratory therapists (RTs) (n = 46, 16%), attending and fellow physicians, hospitalists, and advanced practice providers (APPs) (n = 62, 22%), physical, occupational, and speech-language pathology therapists (n = 25, 9%), and pharmacists (n = 7, 2%). Measurements and Main Results: Respondents widely agreed that increased workload (78%-100% across roles), communication (53%-84%), and lack of RT-directed ventilator weaning (68%-88%) are barriers to implementation. Other barriers differed by role. In 2020, nurses reported liability (59%) and personal injury (68%) concerns, patient severity of illness (24%), and family discomfort with ICU liberation practices (41%) more frequently than physicians and APPs (16%, 6%, 8%, and 19%, respectively; P < .01 for all). Between 2017 and 2020, some barriers changed: RTs endorsed discomfort with early mobilization less frequently (50% vs 11%, P = .028) and nurses reported concern for patient harm less frequently (51% vs 24%, P = .004). Conclusions: Implementation efforts aimed at addressing known barriers, including educating staff on the safety of early mobility, considering respiratory therapist-directed ventilator weaning, and standardizing interdisciplinary discussion of Pediatric ICU Liberation Bundle elements, will be needed to overcome barriers and improve ICU Liberation Bundle implementation.
