Abstract
Background
Concerns over health-related quality of life (HRQOL) in patients with aplastic anemia (AA) have been increasing worldwide. However, most researches on HRQOL in AA patients have ignored individual-level variability. Thus, our study was designed to explore practical classification of HRQOL and related variables among AA patients.
Methods
A cross-sectional study was conducted from May 2022 to March 2023, utilizing convenience sampling to enroll AA patients. Data of HRQOL, sociodemographic characteristics, and clinical variables were collected. Latent profile analysis (LPA) was used to analyze the latent categories of HRQOL in AA patients, utilizing scores from eight subscales of the Medical Outcomes Study 36-Item Short Form Health Survey version 2.0.
Results
A total of 229 patients completed the survey and were included in the analysis. The LPA results showed significantly individual differences and identified three subgroups of HRQOL: Group 1, poor HRQOL with role emotional limitation (n = 54, 23.58%); Group 2, moderate HRQOL with role physical limitation (n = 56, 24.45%), and Group 3, good HRQOL (n = 119, 51.97%), respectively among AA patients. Childless, no comorbidities, transfusion independence, no AA-related symptoms, and higher annual household income were associated with Group 3, whereas higher Eastern Cooperative Oncology Group performance status scores were associated with Group 1.
Conclusions
The findings of our study revealed significant heterogeneity in HRQOL among AA patients, providing valuable information for tailoring interventions to meet individual needs, especially for those in the poor HRQOL with role emotional limitation group.
