The Impact of a Digital Referral Platform to Improve Access to Child and Adolescent Mental Health Services: A Prospective Observational Study with Real-World Data

(1) Background: In the UK, mental health needs for children and young people (CYP) are rising, whilst access to care is declining, particularly in the North of England and post-COVID-19. However, Health Information Technologies (HITs) can simplify access to Child and Adolescent Mental Health Services (CAMHS), reduce waiting times, and provide anonymous support and reliable information. (2) Methods: A single-centre prospective observational study examined the impact of "CYP as One"-a digital referral point to CAMHS-on waiting times and referral rejection rates. (3) Results: Waiting times during the first 12 months of "CYP as One" implementation were compared to the 12 months prior using non-parametric tests. "CYP as One" demonstrated an increase of 1314 referrals, with self-referrals rising by 71%. Initial implementation showed an increase in waiting times by 16.13 days (53.89 days) compared to pre-implementation (37.76 days) (<i>p</i> < 0.001). However, months 10 (M = 16.18, <i>p</i> < 0.001), 11 (M = 17.45, <i>p</i> < 0.001), and 12 (M = 31.45, <i>p</i> < 0.001) implementation showed reduced waiting times. Rejection rates rose due to a 108% increase in referral volume. "CYP as One" improved access and reduced waiting times after the initial phase. (4) Conclusions: Further research is needed to assess its long-term impact and cost-effectiveness, particularly regarding specific mental health conditions and staff time.
