Prevalence and Risk Factors of Anaemia in Older Hospitalised Patients:

摘要

Introduction:We aim to investigate the prevalence and risk factors for anaemia among the elderly in a tertiary hospital.Methods:A retrospective study was conducted on 742 consecutive geriatric patients who were admitted to the medical unit of our hospital. The demographic and laboratory values for patients were examined. Anaemia-related data were studied. Patients with no/missing demographical or laboratory data and those who passed away after admission were excluded.Results:There was a high prevalence of anaemia in the study population. Although there were a significant proportion of nutritional causes, non-nutritional causes formed the majority. Significant risk adjusted risk factors associated with anaemia are male gender, Charlson's co-morbidity index and abnormal serum creatinine levels ≤60ml/min. (OR=1.469 [1.177–1.833], p=0.001; OR=1.147 [1.107–1.189], p0.001; OR=1.335 [1.064–1.675], p=0.013 respectively.) Contributory factors for sub-types of anaemia were further investigated.
