Anemia in elderly patients ≥65 years of age: a hospital-based cross-sectional study

Introduction: Anemia in elderly patients of any degree contributes significantly to morbidity and mortality and has a significant effect on the quality of life. Despite of high prevalence, very few studies have examined the effect of anemia in elderly patients in India. Hence, this study is undertaken to know the prevalence and clinicopathological pattern of anemia in elderly patients. Objectives: 1. To estimate the prevalence of anemia in the elderly aged 65 years and above. 2. To determine the severity, clinicohematological patterns, and causes of anemia in the elderly aged 65 years and above. Materials and Methods: A hospital-based descriptive cross-sectional study was done. The study was conducted for 1 year; during this period, elderly patients aged 65 years and above admitted for other medical conditions were recruited in the study using consecutive sampling technique until the desired sample size of 236 was achieved and they were evaluated for anemia. Among them with hemoglobin cutoff value <13 g% for men, <12 g% for women were further evaluated to known the cause of anemia and its clinicohematological pattern. Ethical committee approval was obtained. Data were analyzed using SPSS Software version 23.0. Results: The mean age of the participants was 73.9 ± 7.4 (standard deviation [SD]) years. Majority, 53.8%, of the participants were males. Among the 236 elderly patients, recruited in the study 65.3% were anemic and among them 44.2 had mild anemia and 37% had moderate anemia. Mean hemoglobin value of the participants was 10.7 ± 2.83 SD and it ranged from 3 to 16.3 g/dl. There was no significant difference in the hematological parameters between male and female elderly patients in the study. The main cause of anemia was found to be due to chronic diseases followed by iron‑deficiency anemia. Conclusion: This study concludes that anemia was highly prevalent among elderly patients and most of them had identifiable and treatable etiology. Hence, all elderly patients with anemia should be evaluated properly for underlying etiology and treated accordingly to reduce the mortality and morbidity in elderly patients with multiple comorbidities.
