| Is medication sometimes modified following the screening? | 5 | 6 | 6 | |
| Are the non-pharmacological measures optimised before starting medication? | 2 | 3 | 5 | |
| Prevention of delirium: physical therapy and early mobilisation | Physical therapy: there are structural arrangements with physical therapist and there is agreement about how to provide early physical therapy and mobilisation? | 2 | 3 | 6 |
| Mobilisation of patients is basically addressed by daily patient rounds and this is implemented in the daily rounds? | 4 | 5 | 6 | |
| Is department policy that seeks to mobilise ventilated patients if possible? | 3 | 4 | 5 | |
| Prevention: sleep hygiene | Is there a protocol regarding sleep promotion? | 3 | 6 | 6 |
| Used this protocol and regularly followed in practice? | 0 | 5 | 5 | |
| Sleep protocol contains at least the next recommendations: lights off or muted overnight, strive for sleep (no standard rounds running if not necessary), and use of earplugs? | 5 | 5 | 6 | |
| Prevention: psycho hygiene (among other, reducing sensory deprivation) | Is there a structural focus on using eyeglasses and of hearing aid if applicable throughout the ICU admission? | 4 | 5 | 6 |

| Daily rounds checklist is implemented and used? | 3 | 4 | 5 | |
| Sedation | Sedation with midazolam (or other benzodiazepines) by continuous infusion is avoided, and alternative sedation (analgo-sedation with opiate and possibly clonidine/dexmedetomidine/propofol targeting addressable patient comfortable?) is used? | 4 | 5 | 6 |
| Family engagement | Is there a leaflet about delirium for family? | 4 | 4 | 6 |

| Poster about family engagement by delirium is presented in the family room? | 1 | 2 | 5 | |
| TOTAL (of max 113) | 59 (52%) | 84 (74%) | 106 (94%) | |
*IRT, Implementation Readiness Test, drafted to measure the actual exposure to implementation strategies as perceived by the local study team. All three IRT overviews were made in phase III during the implementation of guideline (total time=10 months). The last one IRT overview was made just before the start of third data collection period (T3).
†The numbers indicate the number of sites that have implemented the item in daily practice.
‡Not applicable for two ICUs because there were no new employees during previous period.
§Not applicable for one ICU because the information as given in pocket cards was integrated in PDMS.
¶Not applicable for one ICU because no PDMS system was available.
