  1. Each regression model controlled for age, gender, co-morbidity and the main effects of frailty and demographic/psychosocial factors.
  2. §For each psychosocial factor with a ‘poor’ ranking, poor was considered as the lowest quartile.
  3. Abbreviations: HR Hazard Ratio, CI confidence interval, GAI-SF Geriatric Anxiety Inventory – Short Form, GDS-SF Geriatric Depression Scale – Short Form, LOS Length of Stay, GEMU Geriatric Evaluation and Management Unit. Significant factors are highlighted in BOLD.
