摘要

Background

ChatGPT has quickly gained popularity as a source of online health information (OHI). However, it is unclear how having a usual source of primary care (USPC) is related to OHI-seeking.

Objective

Explore how having a USPC and other characteristics thought to affect access-to-care influence the use of ChatGPT and other OHI forms.

Design

Cross-sectional national survey.

Participants

Adult members of ResearchMatch, a non-profit affiliate of the National Institutes of Health, between June and August 2023.

Main Measures

The survey evaluated demographics, health characteristics, and OHI-seeking behaviors, including ChatGPT usage. OHI sources were categorized as “passive” (Google, Wikipedia, WebMD) and “interactive” (forums, Q&A sites, ChatGPT). Descriptive statistics, t-tests, and chi-square tests compared users by USPC status. Multiple logistic regression estimated adjusted effects on ChatGPT use.

Key Results

Of 21,499 adults invited to participate in the survey, 2406 (11.2%) responded. Among respondents, 56% reported having a USPC. Those with a USPC, compared to those without, were older, spoke English as their primary language, had higher income, and had more formal education (all p<.001). Participants with a USPC were more likely to use passive OHI (OR 2.46, 95% CI 1.55–3.90, p<.001) and less likely to use interactive OHI (OR 0.73, 95% CI 0.60–0.89, p=.002) or ChatGPT (OR 0.56, 95% CI 0.44–0.71, p<.001). Age over 50 (OR 0.11, 95% CI 0.06–0.20, p<.001), non-White race (OR 0.51, 95% CI 0.38–0.70, p<.001), very good or better health (OR 0.71, 95% CI 0.55–0.92, p=.009), and college education (OR 0.61, 95% CI 0.39–0.97, p=.035) were inversely related to ChatGPT use.

Conclusions

In this national survey of patients participating in a clinical research matching service, those with regular primary care access relied less on ChatGPT, suggesting that a personal primary care relationship may attenuate the need or motivation to use AI-derived OHI.
