Mortality in the Oldest-Old Adults After Discharge From Acute Geriatric Ward.

To examine risk factors for post-discharge mortality in the oldest-old patients. We have assessed the risk factors for mortality after discharge from acute geriatric ward in 448 patients aged ≥90. Low albumin, high urea, and full dependence were risk factors for mortality within 1 month and within 1 year after discharge from hospital. Age-adjusted Charlson Comorbidity Index score, neuroleptic drug treatments and frailty were specific risk factors for post-discharge mortality within 1 year. By Cox regression analysis, the risk factors associated with higher hazard ratios for post-discharge mortality within 14 years follow-up were age-adjusted Charlson Comorbidity Index score, poor functional status, anemia and dementia as comorbidities, neuroleptic drug treatments, low albumin, high urea, and high vitamin B12. Optimal treatment of the condition due to which the patient has been hospitalized and of the medical complications that occurred during hospitalization, while preventing functional decline, might secure longer post-discharge survival.
