High-Frequency Utilization of the Outpatient Messaging System in a Specialized Outpatient Catatonia Clinic for Individuals with Autism Spectrum Disorder.

Abstract

Purpose: Catatonia is a highly morbid psychomotor disorder that impacts autistic adults and children. There is very little literature that describes outpatient catatonia management practices, none of which discusses the use of the electronic health record (EHR). Thus, we conducted this study to analyze patient messages in a specialized catatonia clinic. Methods: We conducted a retrospective analysis of messaging practices in the EHR for patients in a specialized clinic with autism and catatonia from July 1, 2021, to May 31, 2024. Catatonic symptom severity was recorded via the Bush Francis Catatonia Rating Scale (BFCRS), Kanner Catatonia Severity Scale (KCS), and Kanner Catatonia Examination (KCE). We conducted Spearman and Pearson correlation coefficients to determine whether a relationship exists between the frequency of patient messages, catatonic symptoms, and length of follow-up. Results: A total of 12,972 messages were sent to the health system or received by the patient or their family. Of those, 6375 (49.1%) messages were sent from the family to the health system. Relationships between message frequency to the health system and all baseline catatonia severity scores (BFCRS, KCS, KCE) were not statistically significant, although message frequency was strongly associated with length of follow-up (r = 0.65, p < 0.001). A total of 5555 (42.8%) messages were sent directly to or received from providers in the catatonia specialty clinic. The rate of messages to providers in the catatonia clinic was 2.9 messages/day. Conclusion: The frequency of patient messaging was high in this catatonia specialty clinic. Health systems should consider this possibility when planning for similar service lines.
