RESUMEN
PURPOSE: To test associations between health literacy and clinical outcomes in patients undergoing hematopoietic stem-cell transplantation (HSCT). METHODS: English- and Spanish-speaking patients age ≥ 18 years were recruited while admitted for first allogeneic HSCT. Associations between low health literacy (Newest Vital Sign ≤ 3 or Short Test of Functional Health Literacy in Adults ≤ 22) and HSCT outcomes were evaluated. RESULTS: Twenty-eight percent of 177 participants had low health literacy by Newest Vital Sign. None had low health literacy by Short Test of Functional Health Literacy in Adults. There was no statistically significant difference between patients with low and adequate health literacy in hospital readmissions (60% v 54%, P = .4), 2-year overall survival (58% v 66%, P = .19), 2-year cumulative incidence of nonrelapse death (16% v 10%, P = .35), and acute graft-versus-host disease (53% v 44%, P = .3). In multivariable analyses, there were no significant associations between health literacy and clinical outcomes. CONCLUSION: In this cohort of patients undergoing HSCT, we did not identify a relationship between health literacy and clinical outcomes. Although we did not find statistically significant associations between health literacy and HSCT outcomes, interventions to address health literacy should be considered, given complex outpatient care and evidence for adverse outcomes associated with health literacy in similar diseases.
