What does this research mean for the field?

Detected delirium prevalence in Australian and New Zealand healthcare sites is 16%, and while assessment practices and non-pharmacological strategies are widely used, substantial antipsychotic use and workforce barriers remain. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Implication

Cross-sectional study reports a 16% detected delirium prevalence in hospitalised inpatients, highlighting persistent reliance on antipsychotics despite non-pharmacological care.

Key Points

To describe the detected prevalence of delirium and characterize current delirium assessment, prevention, and management practices across Australian and New Zealand healthcare settings.
Sub-analysis of Australian and New Zealand data from an international cross-sectional survey conducted on World Delirium Awareness Day 2023.
Audited delirium assessment tools, frequencies, and interventions across 257 inpatient wards of diverse medical specialties and acuity levels using local clinical practices.
Detected delirium prevalence was 16% at both 8:00 AM (n = 637/4033) and 8:00 PM (n = 609/3836), with ward assessment rates reaching 63% at both time points (n = 4033/6369 and n = 3836/6091).
Validated screening instruments (primarily 4AT and CAM) were used on 93% of wards, alongside widespread non-pharmacological interventions such as hydration (87%), mobilisation (84%), and pain management (84%).
Frequent antipsychotic prescribing was reported—notably risperidone (36%), haloperidol (35%), and quetiapine (31%)—with staff shortages (70%) and lack of training time (53%) identified as major care barriers.
