Methods: A mixed human-AI content analysis was conducted using r/AskDocs posts from 2013-2022. From a corpus of 1,048,576 posts, those referencing “insurance” in the title and/or initial post were identified, yielding a sample of N = 15,140. Using GPT-5, self-reported demographic information such as age, gender, race/ethnicity, and geographic location were extracted when provided, and insurance status was classified as insured, uninsured or unclear. An inductive, single-label topic scheme and definitions were then developed. A 300-post subset was used to label and establish a human-coded benchmark; an overlapping portion was independently double coded by additional coders to assess reliability and resolve discrepancies. Finally, a zero-shot prompt designed to produce consistent single-label topic outputs was applied. Topic assignment performance was evaluated by comparing GPT-5 classifications to the human-coded benchmark prior to scaling across all insurance-referenced posts.
Results: Insurance status was classified as uninsured (n = 5,478), insured (n = 5,129), or unclear (n = 1,173). Among adults aged 18 and older, the mean age was 28.16 years. Race and gender were associated with insurance status. In adjusted models, Black/African American posters had higher odds of being uninsured than Caucasian posters (OR = 1.74, p = .003), Hispanic/Latino posters had more than twice the odds of being uninsured (OR = 2.42, p < .001), and male posters had higher odds of being uninsured than female posters (OR = 1.34, p < .001). Older age was associated with lower odds of being uninsured (OR = 0.98). Topic distribution also differed significantly by insurance status, χ²(106) = 1002.26, p < .001. Uninsured posters were more likely to be represented in access-related concerns, whereas insured posters were more likely to be represented in posts involving unclear diagnoses and feeling dismissed by providers.
Conclusions and Implications: Insurance-related help-seeking on r/AskDocs reflects inequitable participation in healthcare access and navigation. This study highlights that insurance disparities are visible in online medical help-seeking and suggests that online health forums may offer a useful site for understanding how coverage status shapes care-seeking experiences. Insights from this study may outreach, enrollment support, care navigation, and policy efforts aimed at improving equitable healthcare access.
