Physicians Are Unable to Consistently Predict Patient Health Literacy in a Breast Clinic

Health literacy (HL) is a patient's capacity to understand health information. Low HL is associated with worse cancer outcomes and adherence to treatment regimens. This study aimed to test physicians' ability to predict their patients' HL after an initial consultation to determine if routine HL screening is valuable.

From February 2023 through June 2023, patients seen at an academic breast clinic completed a validated, self-reported HL assessment. Surgical and medical oncologists estimated their patients' HL by answering the same HL questionnaire based on their perception of the patient visit. Patient and physician scores were compared using an intraclass correlation coefficient. Linear regression was used to evaluate associations between physicians' ability to predict HL and other variables.

The cohort included 210 patient HL scores with corresponding physician scores for each. Most patients (75.7%) had adequate HL. There was moderate agreement between the patient and physician HL scores (intraclass correlation coefficient = 0.677, P < 0.01), meaning physicians could somewhat predict their patient's HL. Physicians were worse at predicting HL when patients had low HL. There was no difference in physicians' ability to predict HL based on patient age (P = 0.09) or race (P = 0.29). Additionally, we found no difference in the ability to predict HL based on the physician's specialty (P = 0.25).

After an initial consultation, physicians cannot accurately predict patient HL, particularly in patients with lower HL. Given the impact of low HL on a patient's ability to make treatment decisions and adhere to treatment plans, using a validated tool to measure HL is necessary.
