AI-powered self-referral system could close access gap in mental health treatment for racial and gender minorities

In a recently published observational study natural medicineResearchers evaluated the impact of artificial intelligence (AI)-driven self-recommendation chatbots on the diversity and volume of patient referrals across gender, race, and sexual orientation. They found that services using AI chatbots saw significantly higher recommendations than control services, especially among minorities, likely due to the bot’s impersonal nature.

Mental health is considered a global priority by the World Health Organization, with the global population facing increasing challenges. Access to mental health services remains limited due to structural issues such as underfunding and understaffing. Additionally, people with mental health problems often face barriers such as stigma, negative attitudes and structural barriers, particularly those from minority groups and disadvantaged backgrounds. The first step in mental health care includes seeking help and referrals, which are critical for timely support and preventing adverse outcomes. However, there is evidence that individuals from minority groups experience greater barriers and stigma in accessing care.

Digital technologies, including artificial intelligence, offer potential solutions to these challenges, providing flexibility and reducing stigma. Although digital technologies show promise in making mental health care more efficient, their marginal impact on the diverse populations seeking help remains little explored. Digital solutions like chatbots can help individuals overcome barriers and enhance accessibility.

Therefore, the researchers in this study launched “Limbic Access,” a personalized, AI-enabled chatbot designed for self-referral in mental health care by autonomously collecting patient information. Optimize the referral process. The impact of chatbots was assessed through observational studies.

About the study

This retrospective observational study investigated the impact of limbic system access on referrals to talk therapies for anxiety and depression in the UK National Health Service. The chatbot collects clinical information using standardized questionnaires such as the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Assessment (GAD-7), with a semi-standardized structure. AI-driven adaptability helps tailor empathic responses to patients’ mental health conditions and further tailor data collection, optimizing engagement and efficiency.

The study analyzed data from approximately 129,400 patients across 28 services (14 using chatbots and 14 controls), comparing referral patterns before and after chatbot implementation. Select a service with an online referral web form as a comparison. While the chatbot approach offers personalization, online web forms do not. Control groups were matched on various variables, including demographic characteristics. The mechanism of potential differences in AI chatbot recommendations was explored by analyzing the qualitative feedback provided by 42,332 people after the recommendation was completed.

Statistical analysis involved chi-square test, logistic regression, one-way ANOVA and sensitivity analysis.

Results and discussion

Total referrals for services using AI chatbots increased significantly by 15%, while total referrals for control services increased by 6% during the same period. There were no differences in baseline population composition between the two methods. Recommendations from non-binary individuals showed a significant increase of 179% for services using personalized self-recommendation chatbots, compared to a 5% decrease for control services. Additionally, referral rates increased across genders in services using chatbots – 16% for men and 18% for women, compared to 5% and 6% respectively in the control service. No significant differences in the number of referrals were observed based on an individual’s sexual orientation.

The use of AI chatbots resulted in a significant 29% increase in minority referrals, exceeding the 10% increase observed in the matching control service. Whites also experienced a 15% increase, significantly higher than the matching service’s 4% increase.

Detailed analysis shows that services using self-recommendation chatbots outperformed their respective control services with a 39% increase in Asian and Asian British groups, a 40% increase in black and black British groups, and a 15% increase in mixed race groups. However, the differences between mixed-race and other-race groups were not significant compared with matched controls.

Qualitative data analysis through natural language processing revealed different patterns across different demographic groups. Overall, 89% of feedback was positive, emphasizing convenience, hope and reducing stigma. Notably, gender minorities highlighted the lack of human involvement, addressing underlying stigma and judgment.

Asian and black groups reported an increase in self-actualization but expressed less hope. Neutral responses were higher among Asian and Black groups, indicating potential barriers to seeking mental health support. Manual coding analysis validated these findings, highlighting the relevance and robustness of the observed patterns.

The general increase in referral volumes and improvements in diversity resulting from the use of chatbots did not appear to have a negative impact on clinical assessment wait times or the number of assessments. This indicates that quality of care is maintained. Another study comparing AI chatbots, generic chatbots, and standard web forms showed that personalized AI-enabled chatbots significantly outperformed the overall user experience.

in conclusion

This study highlights the potential role of artificial intelligence-based chatbots in enhancing digital self-recommendation formats and access to mental health care services. In the future, these findings may contribute to global health strategies and initiatives to reduce the burden of mental health conditions and inequalities in access to health care.
