Providers' Inability To Estimate Health Literacy Among African American (Aa) Patients (Pts) With Early Prostate Cancer (Pca).

77 Background: Providers’ estimates of a pt’s health literacy are important for communication and shared decision making among men with early PCa. We explored differences between providers’ estimates of health literacy and measured health literacy among AA pts in a prospective cohort study at Grady Memorial Hospital and the Atlanta Veterans Administration Hospital. Methods: Providers (n=18) estimated the health literacy of 124 newly diagnosed, early-stage, AA PCa pts after discussions with each pt regarding his PCa treatment options, categorized as ≤Grade (Gr) 3; Gr 4-6; Gr 7-8; and High school. At a subsequent visit, prior to choosing his cancer treatment, each pt’s health literacy was measured using the Rapid Estimate of Adult Literacy in Medicine (REALM), using the same categories. Domains of numeracy, comprehension of common PCa terms, and anatomic knowledge were assessed using published methods. Concordance between estimated and actual health literacy was evaluated via Cohen’s Kappa coefficient (1.00 = perfect agreement). Results: Despite their discussions with the pts, providers consistently overestimated pts’ health literacy. Agreement between provider estimates and pts’ measured values was consistently low (32.0%-37.6%). These rates were approximately what would be expected by chance. Among the 75 patients with the lowest levels of health literacy, agreement was even lower (12.3%-35.6%). In this group 26.7% of provider assessments were off by ≥2 REALM categories. Conclusions: Healthcare providers are surprisingly ineffective at estimating the health literacy of their pts with early stage PCa. This poor accuracy may diminish providers’ ability to communicate successfully with pts and engage in shared decision making, especially among pts with poor health literacy. [Table: see text]
