Table 2 Instruments and measures used to assess implementation feasibility and success (adapted from PUN et al.) [16]

From: Every child, every day, back to play: the PICUstars protocol - implementation of a nurse-led PICU liberation program

Instrument Target population Study phase Outputs
Empathic 30-AUS questionnaire Parents of eligible children From phase 2 onwards Family engagement and satisfaction
PICU Liberation knowledge and perceptions questionnaire PICU staff Phase 2, 3 and 4 Drivers, barriers, knowledge gaps
Organisational readiness questionnaire PICU staff, organisational leadership teams Phase 2, 3 and 4 Drivers, barriers, leadership effectiveness, culture and employee morale or satisfaction/meaning making
Daily Goal checklist PICU staff Phase 3 Proportion of Liberation goals set
Check-in Audit PICU staff Phase 3 Drivers, barriers, knowledge gaps
Measure Definition Study Phase Outputs
Feasibility ≥ 75% bundle compliance (daily goals set) at 1 year Phase 3 Control charts of bundle compliance
Bundle fidelity (bundle compliance):
Compliance with daily patient screening for PICU Liberation program using the daily goals checklist; eligible bundle element performed per patient day
≥ 75% absolute and/or ≥ 25% improvement from baseline compliance rate of checklist completion Phase 3 Control charts of liberation goals set and bundle element activities performed per eligible patient day
Bundle performance impact of bundle on process and quality of care (the practices that the bundle was designed to influence) Phase 3 Complete performance is measured by a patient-day in which every eligible element of the bundle was performed (i.e., 100% of the bundle versus anything less) and “proportional performance” as the percentage of eligible elements a patient received on a given day (i.e., “bundle dose”). This will be measured only if the patient was in the PICU for a full 24 h (Table 4)
