Agreement of ethnicity reporting among patients with cancer with acute coronary syndrome: a national multiregistry analysis
- national multiregistry analysis
- four national datasets
- three linkages
Authors' conclusion
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.
Study context
- Population
- Patients with cancer with acute coronary syndrome (ACS) (2000–2018)
- Comparison
- Agreement of ethnicity coding and outcomes across NCRAS-MINAP, NCRAS-MINAP-BCIS, NCRAS-MINAP-HES linkages
Main finding
As reported in the abstract
Concordant ethnicities
Concordant (range across three linkages)
52.4%-53.8%
Further findings
Discordance
- Discordant (range)
- 1.2%-5.5%
Missingness
- Missing in 1 dataset
- 28.6% and 43.4%
- Missing in ≥2 datasets
- 1.6%-12.6%
Ethnicity correlation between individual datasets
- Correlation poor, lowest between National Cancer Registration and Analysis Service (NCRAS) and BCIS
- r=0.318
1-year and long-term cardiac and cancer deaths · 1-year and long-term (≤5 years)
- Higher in several of the Missing (1 and ≥2 datasets) groups compared with the Concordant group
