We assessed whether patients ever logged in, and their login rates, during hospitalizations and intensive care unit (ICU) admissions. Multivariate logistic and Poisson regression models evaluated relationships between demographic and care characteristics and inpatient portal usage.<\/jats:p>\n                  <jats:p>Results Of 28,386 patients, most were female (15,107, 53%), non-Hispanic (24,177, 91%), and White (20,643, 77%); the median age was 65 (interquartile range [IQR]: 54.75) and the median length of stay was 4 days (IQR: 2\u20138). A total of 65% (18,588) logged in at least once during hospitalization. Patients who were Black (odds ratio [OR] = 0.68, 95% confidence interval [CI]: 0.62, 0.74, p &lt; 0.001; incidence rate ratio [IRR] = 0.68, 95% CI: 0.62, 0.73, p &lt; 0.001), single (OR = 0.80, 95% CI: 0.75, 0.86, p &lt; 0.001; IRR = 0.88, 95% CI: 0.83, 0.93, p &lt; 0.001), and with Medicaid insurance (OR = 0.79, 95% CI: 0.71, 0.87, p &lt; 0.001; IRR = 0.86, 95% CI: 0.8, 0.94, p &lt; 0.001) were, respectively, 32, 20, and 21% less likely to use the portal at least once, and their login rates were 32, 12, and 14% less, compared with White, partnered, and commercially insured patients. Of the 1782 patients with ICU admissions, 971 (55%) logged in at least once during hospitalization. Black patients were 41% (OR = 0.59, 95% CI: 0.43, 0.80, p &lt; 0.001) less likely to use the portal at least once and their login rates were 41% less (IRR = 0.66, 95% CI: 0.51, 0.85, p = 0.001) than White patients.<\/jats:p>\n                  <jats:p>Conclusion We uncovered disparities in hospitalized cancer patients\u2019 portal usage by race, insurance, and partnership status. Future work should explore the underlying reasons and leverage these insights so that portal onboarding processes and interface designs address the needs of all
