Delirium and cognitive assessment in national hip fracture registries: a scoping review

Aim: This scoping review aims to identify delirium and cognitive assessment data items that are currently collected by national hip fracture registries (HFRs), to identify registry guidance for the administration of delirium and cognitive assessment tools across HFRs, and to report outcomes of these data items in the most recent annual reports of identified HFRs. Findings: Of 22 eligible HFRs, 14 (64%) collected delirium assessment data, and 18 (82%) collected cognitive assessment data. There was heterogeneity in recommended delirium and cognitive assessment tools (although 50% recommended the 4AT), cut-off scores, and tool completion and positive score rates. Message: While most identified HFRs recommended delirium and/or cognitive assessment, there was considerable variation in methods of assessment and documentation. Greater standardisation in data items and their collection could improve international comparability and patient care.
