Identification of low health and cancer literacy in oncology patients: a cross-sectional survey.

Health literacy is a significant public health concern, particularly given the increased complexity of chronic disease health management and health system navigation, and documented associations between low health literacy and poor health outcomes. This study therefore aimed to identify the proportion and characteristics of outpatients visiting a specialist cancer hospital who report low health literacy and/or low cancer health literacy. This study used a cross-sectional survey administered verbally with patients attending a specialist cancer hospital located in Melbourne, Australia over a two-week period. Process data on conducting health literacy screening within a clinical setting was collected. Those identified with inadequate general health literacy were different to those identified with low cancer-specific health literacy, although overall both proportions were low. Cross-sectional screening of patients was difficult, despite utilising verbal surveying methods designed to increase capacity for participation. Health literacy screening using the tools selected was not useful for identifying or describing patients with low health literacy in this setting, given the disparity in those categorised by each measure. Until the theoretical construct of health literacy is better defined, measurement of health literacy may not be clinically useful.
