Introduction
The primary aim of this study was to identify risk factors for delirium after hip fracture surgery. The secondary purpose was to verify peri-operative clinical outcomes, adverse events and mortality rates in delirium patients after hip fracture surgery.
Material & methods
A prospective hip fracture database was used to obtain data. In total 2051 patients older than 70 years undergoing a hip fracture surgery between 01-01-2018 and 01-01-2021 were included. A delirium was diagnosed by geriatrician based on the DSM-V criteria.
Results
The results showed that 16% developed a delirium during hospital admission. Multivariable analysis showed that male gender (OR1.99, p<0,001), age (OR1.06, p<0,001), dementia (OR1.66, p=0,001), Parkinson"s disease (OR2.32, p=0.001), Δhaemoglobin loss (OR1.19, p=0.022), pneumonia (OR3.86, p<0,001), urinary tract infection (UTI) (OR1.97, p=0.001) and wound infection (OR3.02, p=0,007) were significant independent prognostic risk factors for the development of a delirium after hip surgery. The median length in-hospital stay was longer in patients with a delirium (9 days) vs. patients without a delirium (6 days) (p<0,001). The 30-day mortality was 7% (with delirium 16% vs. with no delirium 6% (p<0.001)).
Conclusion
Significant independent prognostic factors associated with delirium after hip surgery were male gender, age, dementia, Parkinson"s disease, Δhaemoglobin loss, pneumonia, UTI and wound infection.
