Prevalence of Anemia and Associated Factors Among Older Patients in the Outpatient Department of Phramongkutklao Hospital
Main Article Content
Abstract
Background and Objectives: Anemia in older people is a common condition in Thailand and worldwide, causing many complications affecting patients' and caregivers' physical and mental health, leading to economic losses at individual, community, or national levels. Accordingly, this study aimed to determine the prevalence and risk factors associated with anemia in older patients.
Design: Descriptive Cross-sectional study
Materials and Methods: The study was performed on patients aged 60 and over visiting the Outpatient Department of Phramongkutklao Hospital. A questionnaire regarding factors associated with anemia in older patients and the Mini Nutritional Assessment (MNA®) was collected from June to December 2022. The data were analyzed by using descriptive statistics and logistic regression.
Results: Of the 88 participants, the prevalence of anemia in older patients was 29.5 percent. Risk factors associated with anemia in older patients are patients aged 80 and over (OR 10.154, p 0.007), eGFR 30 to 59 ml/min/1.73m² (OR 5.25, p 0.016), polypharmacy (OR 3.972, p 0.022), having at least four chronic diseases (OR 4.24, p 0.003), diabetes mellitus (OR 2.939, p 0.03) and chronic kidney disease (OR 7.125, p 0.001).
Conclusions: One significant factor associated with anemia in older patients is chronic kidney disease. The most common population groups having anemia are patients aged 80 and over, polypharmacy, having at least four chronic diseases, and diabetes mellitus. Therefore, the healthcare provider teams should perform holistic and continuous care. Moreover, prevention strategies should be provided to reduce complications that can lead to disability in the future.
