Delirium is a clinical syndrome of acute confusion which is particularly common in critically ill Intensive Care patients. Delirium on ICU is associated with adverse health outcomes including increased mortality, length of stay, readmission, discharge to long term care, dementia, falls and pressure sores. It can be distressing for both the person affected and their family and carers.  Delirium on ICU can be triggered by medications, especially those with an anticholinergic effect.

PIONEER has curated a highly granular dataset of 9,100 spells admitted to intensive care. This includes timestamped medication prescriptions and administration with cognition scores. Also, demography, serial physiology, consult specialties, diagnostic codes (ICD-10 & SNOMED-CT), initial presentation, presenting symptoms, serial physiology, all investigations, all medications (name, dose, route), anticholinergic burden (AEC) scores, and outcomes. The current dataset includes admissions from 01-01-2021 to 31-12-2023 but can be expanded to assess other timelines of interest.

Data set availability: Data access is available via the PIONEER Hub for projects which will benefit the public or patients. This can be by developing a new understanding of disease, by providing insights into how to improve care, or by developing new models, tools, treatments, or care processes. Data access can be provided to NHS, academic, commercial, policy and third sector organisations. Applications from SMEs are welcome. There is a single data access process, with public oversight provided by our public review committee, the Data Trust Committee.
