aOR, adjusted odds ratio; CI, confidence interval.
n = 6789.
↵* Asians, Pacific Islanders, and multiple races.
↵† Question was omitted in 2018 H5C2, so n = 3285 based on H5C1 only.
Bolded cells are statistically meaningful.
Participants in H5C2 were asked the number of times that they accessed their own medical records only if they responded “yes” to whether they have been offered online access to medical records. Participants then reported who offered them access (i.e., healthcare provider, health insurer, someone else). To harmonize the data, we coded participants who said “no/don’t know” to “have you been offered online access to your medical records?” as “no” and those who selected “healthcare provider” to “who offered you online access to your medical records?” as “yes.”
Logistic regression analysis modeled the probability of 1 (eg, provider maintained electronic medical records, provider offered access to electronic medical records).
