Abstract
BACKGROUND: Health literacy represents the degree to which patients can understand and act on health information. The relevance of health literacy to health care delivery, outcomes, and overall surgical care is unambiguous. This study aimed (1) to determine the prevalence of limited health literacy in patients diagnosed with Dupuytren's contracture and (2) to identify independent predictors of limited health literacy. METHODS: This cross-sectional study included patients with Dupuytren's disease and with self-reported English fluency. The Newest Vital Sign, a rapid, validated, and reliable screening tool, was selected to measure health literacy. An exploratory multivariable logistic regression model was used to identify possible predictors of limited health literacy. RESULTS: A total of 185 patients met eligibility criteria and were included. From those, 82 (44 percent) were found to have limited health literacy, defined as a score of 3 or less on the Newest Vital Sign. The domain of prose literacy was most highly scored compared to numeracy and document literacy. Lower household income was associated with a 4.7-fold increase in the odds of having limited health literacy. Being an immigrant also increased the odds of having limited health literacy by a factor of 3.6. Sensitivity analyses and subgroup analyses (based on education, maternal language, and immigration status) corroborated these independent predictor findings. CONCLUSIONS: Limited health literacy is common among patients with Dupuytren's contracture. System level changes are necessary such as the access and integration to clinical care of universal measures of support to promote productive patient-surgeon interactions.
