Abstract Background: Adults with breast cancer (AwBC) often experience psychological and mental health challenges and face many barriers to accessing mental health care and services. Telemedicine can help facilitate access to these care and services and AwBC may benefit uniquely from virtual care. However, little is known about the relationships between virtual care access (VCA) and psychological and mental health conditions in AwBC nationally. Methods: We obtained a population-based sample from the 2021 National Health Interview Survey that used stratified clustering sampling to interview US adults. This study was limited to adults who ever had breast cancer. VCA was defined as having had a virtual (i.e., phone or video) medical visit with a health provider in the past 12 months and was categorized as “yes/no.” Serious psychological distress, measured using the 6-item Kessler scale, was dichotomized based on a cutoff score of 13. Having an anxiety disorder or depression was self-reported as “yes/no.” Weighted proportions and 95% confidence intervals (CI) were tabulated and compared using Rao-Scott chi-square tests. Multivariable logistic regression models were fit to calculate adjusted odds ratios (AOR) and 95% CIs. All statistical analyses accounted for complex sample design and survey weights. Results: The unweighted sample size was 698, representing a weighted sample of 4,379,870 AwBC in the US. The mean age was 67.7 years; 77.6% were White and 9.6% were Black; 53.8% and 38.9% were privately insured and on Medicaid/Medicare, respectively. Of the total, 20.9% (95% CI: 17.3-24.6%) had depression, 17.4% (95% CI: 14.0-20.9%) had an anxiety disorder, and 3.2% (95% CI: 1.7-4.7%) experienced serious psychological distress. Overall, 50.3% (95% CI: 46.1-54.4%) had a virtual visit. White AwBC reported a higher proportion of VCA than Black AwBC (50.6% vs. 38.6%). AwBC on Medicaid/Medicare reported a lower proportion of VCA than those privately insured (47.8% vs. 51.8%). AwBC who experienced serious psychological distress had a higher percentage of VCA than those who did not (78.5% [95% CI: 60.8-96.2%] vs. 48.5% [95% CI: 44.2-52.8%], p=.007). Compared with AwBC who did not have depression, those who did had a higher percentage of VCA (63.9% [95% CI: 54.6-73.2%] vs. 46.6% [42.0-51.3%], p=.002). Similarly, AwBC with an anxiety disorder reported a higher percentage of VCA than those without (60.4% [95% CI: 50.3-70.6%] vs. 48.1% [43.6-52.6%], p=.032). Furthermore, AwBC who frequently felt anxious or depressed were more likely than those who felt less frequently to use telemedicine. In the adjusted regression models, AwBC experiencing serious psychological distress had significantly greater odds of VCA than those not experiencing (AOR=3.79, 95% CI: 1.05-13.7). AwBC with depression had significantly greater odds of VCA than those without (AOR=2.02, 95% CI: 1.25-3.28). Although AwBC with an anxiety disorder also had greater odds of VCA than those without (AOR=1.45, 95% CI: 0.89-2.38), the association was not statistically significant. Conclusions: In this nationally representative sample of US AwBC, more than one in 6 had an anxiety disorder or depression and VCA was prevalent in the past 12 months. AwBC with serious psychological distress, anxiety, or depression were more likely than those without to use telemedicine, indicating a greater need for virtual care among AwBC. Our findings also suggest that to help AwBC improve their psychological and mental health conditions and address their unmet needs, breast cancer support programs would need to ensure equitable access to virtual care and services in this patient population.
