Missing ethnicity data in patients with cancer and acute coronary syndrome was linked to higher cardiac or cancer mortality, indicating significant health disparities.
Inconsistent ethnicity reporting in national registries for cancer patients with ACS is common and associated with higher mortality, hindering the study of health inequalities.
Absolute Event Rate: 0% vs 0%
Across four national datasets for patients with cancer with ACS, nearly half of patients had missing ethnicity in at least one dataset, which was associated with higher cardiac or cancer mortality. Inconsistency in ethnicity coding represents a missed opportunity to examine health inequalities in this high-risk and understudied population.
