The impact of health literacy on diagnosis and outcomes of symptomatic cancer by ethnicity: a systematic review protocol.

ABSTRACT: BACKGROUND:Ethnic minorities in multi-ethnic societies like the UK and USA have poorer outcomes for some cancer types when compared with the majority. The causes of ethnic inequalities in cancer outcomes are complex and not fully understood. In particular, the potential role of health literacy on symptomatic presentation and diagnostic interval (the period between first consultation within primary care and definitive diagnosis of cancer) by ethnicity is unknown. Given the increasing need for shared decision-making and patient involvement in the diagnostic process, understanding the potential impact of the differences in health literacy may help redress ethnic inequality in cancer outcomes. The present study aims to critically examine the evidence in this area. METHODS:Seven electronic databases will be searched using keywords and controlled vocabulary related to ethnicity, health literacy, cancer diagnosis and cancer outcomes. Citations and bibliography searches of included studies will be performed to identify relevant studies that have cited eligible articles. Authors of included studies will be contacted to identify unpublished studies. Eligible studies will be restricted to primary cancers. Study quality will be evaluated in using the Critical Appraisal Skills Programme (CASP) checklists. A descriptive summary of selected studies will be presented, and the synthesis will follow a narrative framework. DISCUSSION:This systematic review will summarise the evidence regarding ethnic inequality in health literacy and how this impacts on diagnosis and outcomes of cancer. The review will identify possible areas for future research, and inform clinical practice and interventions to reduce ethnic inequalities in cancer diagnosis and outcomes.
