Data from: Assessing completeness of cancer family history in EHRs using genetically-defined kinships: a cross-sectional study

The data in this submission is intended to allow others to replicate the
results reported in our study article “Assessing completeness of cancer
family history in EHRs using genetically-defined kinships: a
cross-sectional study,” published in Genetics in Medicine Open in 2025. In
this study, we leveraged genetic data from the Healthy Nevada Project to
identify patients at Renown Health (a large regional hospital in Reno,
Nevada) who were related by blood. We then examined the electronic health
records of patients with cancer-affected blood-relatives to see whether
their relatives’ cancer type was successfully documented in the patient’s
family history record. Across all cancer types, 45.2% (95% confidence
interval: 42.0-48.4%) of cancers were successfully documented. Here we
provide the data and R code used to fit the generalized estimating
equations used to produce the key results in our study. If additional data
is desired, please see the data availability statement included with our
study article for details on access criteria.
