ReviewIncidence of postoperative delirium in surgical patients: An observational retrospective cohort study.
SummaryPerioperative neurocognitive disorders including postoperative delirium (POD) are common complications of anaesthesia and surgery, associated with morbidity, mortality and a large economic cost. Currently, limited data are available on the incidence of POD in the New Zealand population. The objective of this study was to utilise New Zealand national level datasets to identify the incidence of POD. ⋯ A diagnosis of POD was associated with increased mortality and hospital length of stay. Our results highlight potential risk factors of POD and disparities in health outcomes in New Zealand. Additionally, these findings suggest systemic under-reporting of POD in national level datasets.
