Comparison of barriers found by the first survey versus the results of the second survey

(A) Attitudes and perceptions%*
 Delirium occurrence and importance
 Delirium is preventable2115
 Is a nurse capable to identify delirium with a validated delirium screening instrument?3480
 When I as nurse suspect a patient to be delirious, I am satisfied with delirium treatment4740
 When I as physician suspect a patient to be delirious, the nurse is satisfied with delirium treatment4211
 Collaboration between doctors and nurses with regard to delirium at the ICU can be improved by better screening6530
 Collaboration between doctors and nurses with regard to delirium at the ICU can be improved by routinely addressing delirium in daily rounds7478
(B) Current practices
 Delirium screening%*
 In the ICU unit where I work the following delirium screening scale is in use:
 CAM-ICU (Before: n=210; in only two hospitals / After: n=119)5845
 ICDSC (before: n=3/after: n=104)<139
 Delirium prevention
 Earplugs for the night824
 Family visits as much as possible5061
(C) Guideline adherence (n=136)
 If I follow the guideline recommendations, it is likely that my patients would not receive optimal care†3.1 (1.0)1.9 (1.1)
 I do not wish to change my delirium care practices, regardless of what delirium guideline recommends†3.7 (1.0)1.4 (1.0)
 I don’t have time to use this guideline†3.5 (0.9)1.7 (1.0)
 This guideline is cumbersome and inconvenient†3.0 (1.1)2.0 (1.1)
(D) Guideline adherence in general (n=128)
 Generally, guidelines are cumbersome and inconvenient†3.0 (0.9)2.2 (0.9)
 Guidelines are difficult to apply and adopt to my specific practice†3.1 (0.9)2.0 (0.9)
 Guidelines interfere with my professional autonomy†3.3 (0.9)1.7 (0.9)
 Generally, I would prefer to continue my routines and habits rather than to change† based on practice guidelines†3.3 (1.0)1.9 (0.9)
 I am not really expected to use guidelines in my practice setting†3.7 (0.9)1.4 (1.0)
  • *= % agreement (= %YES answers or % of the sum of agree and strongly agree answers (from the 5-point Likert Scale statements)). Barriers depends on the question formulation. For positive formulated the barrier is ≤50% and negative formulated the barrier is ≥50%.

  • †= mean and SD based on the six-point Likert Scale. Mean score of ≥3 was considered to indicate agreement with statement=Barrier.

  • CAM-ICU, Confusion Assessment Method for the ICU; ICDSC, Intensive Care Delirium Screening Checklist; ICU, intensive care unit.
