Online patient portals can be used to self-schedule screening mammography (SM). The aim of this study was to investigate the sociodemographic factors associated with the use of an online patient portal to self-schedule SM in an urban academic healthcare system.

Materials and Methods:
Institutional review board approval with a waiver of informed patient consent was obtained for this retrospective cohort study. Data were extracted from the department of radiology scheduling data warehouse. Patients scheduled for SM between February 1, 2021, and September 30, 2022, were included. Metrics included: scheduling pathway, patients’ sex, age, preferred language, race, ethnicity, and health insurance provider, as well as ZIP code to measure the Area Deprivation Index (ADI). Descriptive statistics were reported. The multivariable logistic regression model was constructed to quantify the association between patient sociodemographic variables and the use of the online self-scheduling pathway for SM.

A total of 22,306 patients were scheduled for SM (mean age: 59; 66.8% White; 20.4% Asian; 20.6% Hispanics). Overall, 3566 (15.9%) used the self-scheduling pathway. Older patients (OR, 0.97; 95% CI, 0.96, 0.98), Spanish-preferred language (compared to English) (OR, 0.23; 95% CI, 0.16, 0.33) and Medicaid health insurance (compared to commercial insurance) (OR, 0.68; 95% CI, 0.48, 0.95) patients were less likely to self-schedule. Patients of Hispanic ethnicity (compared to non-Hispanic) (OR, 1.37; 95% CI, 1.18, 1.59), of Asian race (compared to white) (OR, 1.63; 95% CI, 1.45, 1.83), living in most disadvantaged neighborhood (compared to least disadvantaged neighborhood) (OR, 1.16; 95% CI, 1.02, 1.32) and those who self-referred (OR, 73.33; 95% CI, 58.33, 92.20) were more likely to self-schedule.

Online patient portals can be an effective tool for self-scheduling for screening mammography. Sociodemographic differences in online patient portal utilization for screening mammography suggests that self-scheduling may improve some of the barriers that racial/ethnic minority populations, such as Hispanics and Asian, as well as those living in socioeconomically disadvantaged neighborhoods may encounter.
