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