[Research Presentation] Purpose: Nutritional health deteriorates and may fluctuate over time during and posthospitalization. Visualizing how the nutrition changed and studying the determinants of nutritional health during and post-hospitalization is essential in developing a target intervention. The purpose of this study was to characterize the trajectory and to identify determinants of nutritional health over time in a sample of older hospitalized patients, using the Generalized Estimating Equation. Methods: A prospective cohort study was conducted on 306 older hospitalized patients aged 65 years and older. Subjects were recruited from 5 surgical and medical wards at a tertiary medical center in northern Taiwan and assessed at four points in time: within 48 hours after admission, before discharge, and 3 and 6 months post-discharge. Guided by a framework developed by Chen et al. (2007), demographics, visual or hearing impairment, cognitive status, oral health, medication taken, co-morbidities, functional status, social support, and depressive symptoms were tested for their predictability on nutritional health over time. Results: Nutritional health fluctuated significantly over time. The curve dove during hospitalization, bounced back at three months, and rose slightly at 6 months post hospitalization. Decreased cognitive capacity, worsening oral health, increasing use of medications, increasing functional limitation, and raised depressive symptoms all affected nutritional health over time after controlling for length of stay and surgical treatment. The extents of functional status impacting on nutrition varies at different points in time while the predictability of other determinants remained stable. Conclusion: The trajectory of nutritional health is a reflection of the patients' cognitive status, oral health, medication taken, functional status, and depressive symptoms. The findings of present study provide directions for the development of target intervention for inpatient and transitional care. Multi-faceted packages of intervention targeting a range of determinants for managing undernutrition and subsequent decline during and post-hospitalization need to be tested.
