A systematic review of the use of telehealth to facilitate a diagnosis for children with developmental concerns

Background: Telehealth can reduce the gap between developmental concern and diagnosis. Evaluation of telehealth methods is needed for providers to make decisions about using telediagnostic assessments.Aim: This systematic review examined telehealth in facilitating a diagnosis for children with developmental concerns and assessed 1) study characteristics and type of diagnostic evaluation; 2) comparison of telehealth technologies to in-person diagnostic methods; 3) feasibility and acceptability of telehealth technologies; and 4) methodological quality.Method and procedures: Peer-reviewed studies from PsycINFO, CINAHL, Web of Science, PubMed, Embase, and Cochrane published January 2000-July 2021 were searched using "telehealth" AND "developmental concern" AND "diagnosis". Data extraction included study characteristics, diagnostic evaluation, technology, diagnostic accuracy, feasibility, and acceptability. Methodological quality was assessed using NHLBI tools.Outcomes and results: Nine studies met inclusion. Children with suspected FAS, social-emotional concerns, suspected genetic conditions, and failed hearing screenings received a telediagnosis. Evaluations included dysmorphology, feeding, neurological, developmental, audiological, and psychiatric. Seven studies used videoconferencing in real-time and two used Store-and-Forward methods. High diagnostic agreement occurred between face-to-face and remote methods. Stakeholders reported high satisfaction and feasibility. Many of the studies were rated as fair quality. Conclusions and implications: Findings underscore partnership models between local providers and remote specialists. Rigorous study designs with larger samples covering a wider range of developmental domains are needed to provide a stronger empirical base for providers.
