Abstract
INTRODUCTION: Patient portals are increasingly becoming the primary channel for communicating health information, raising concerns about the potential worsening of health care access disparities among limited English proficient (LEP) patients. The authors studied the use of a health plan patient portal and potential barriers to use by comparing LEP Latino and Chinese Health Plan members to those with English language preference (non-LEP). METHODS: The authors used health record data for 480,833 Latino (31.8% LEP) and 137,904 Chinese (31.6% LEP) adult Kaiser Permanente Northern California members 25-85 years of age to study portal use during 2019. Clinic-collected survey data for 489 Latino and 1037 Chinese LEP patients was compared with data for 849 Latino and 426 Chinese non-LEP Kaiser Permanente Northern California 2020 Member Health Survey respondents to identify factors potentially inhibiting portal use. The authors used chi-square tests to assess differences in portal use and potential influencing factors across ethnic, language, and age subgroups. RESULTS: During 2019, LEP Latino and Chinese adults were less likely than non-LEP adults to have a portal account and, among those with a portal account, to have sent secure messages and viewed laboratory results online. Portal use was lower among LEP Latino than LEP Chinese adults. Patient surveys identified lower educational attainment, health literacy, and access to and use of digital tools among LEP vs non-LEP Latino and Chinese adults. CONCLUSIONS: Patient portal use is lower among LEP than non-LEP Latino and Chinese patients. Health care systems should take action to decrease barriers to use, but they also should consider patient communication preferences.
