Abstract
Postoperative pulmonary complications (PPCs) are the leading cause of death following hip fracture surgery. Dementia has been identified as a PPC risk factor that complicates the clinical course. By leveraging electronic health records, this retrospective observational study evaluated the impact of dementia on the incidence and severity of PPCs, hospital length of stay, and postoperative 30-day mortality among 875 older patients (≥65 years) who underwent hip fracture surgery between October 1, 2015 and December 31, 2018 at a health system in the southeastern United States. Inverse probability of treatment weighting using propensity scores was utilized to balance confounders between patients with and without dementia to isolate the impact of dementia on PPCs. Regression analyses revealed that dementia did not have a statistically significant impact on the incidence and severity of PPCs or postoperative 30-day mortality. However, dementia significantly extended the hospital length of stay by an average of 1.37 days.

Dr. Hideyo Tsumura is an Assistant Professor at Duke University School of Nursing and a practicing certified registered nurse anesthetist. She completed her nurse anesthesia education at the University of Tennessee Health and Science Center in 2011. In 2022, she earned her Ph.D. from Duke University and received postdoctoral training at the University of Michigan through the National Clinician Scholars Program. Her research focuses on disparities in anesthesia care and improving patient outcomes.
Eleanor Schildwachter McConnell
Dr. McConnell's program of research focuses on factors that influence functional decline in very frail older adults. She has been funded by the National Institute of Nursing Research and the Department of Veterans Affairs to conduct a series of studies designed to identify modifiable risk factors for worsening self-care disability in long-stay nursing home residents with chronic cognitive impairment. She has also developed and tested a variety of interventions to modify risk factors for worsening disability. Her research builds upon existing knowledge of the bio-physical determinants of disability as conceptualized in the Nagi Disablement Model. Dr. McConnell's academic interests include frailty in the aged, the role of the environment in promoting function, and the conduct and testing of nursing interventions to prevent decline in those with chronic illness.
