METHODS: A cohort retrospective study was conducted at a leading tertiary care hospital in Saudi Arabia spanning from January 2023 to January 2024 in a psychiatry setting. The study comprehensively examined all instances of interventions for DRPs facilitated through patient-initiated telepsychiatry encounters with psychiatric clinical pharmacists. Detailed and meticulously recorded notes from patient chart reviews, documented by the pharmacist in the Electronic Health Record (EHR), during each encounter, were reviewed. These notes provided significant information on psychiatric diagnosis, identified DRPs and the specific interventions and recommendations proposed by the clinical pharmacist to the attending physician. The Krska classification was utilised to classify and analyse the identified DRPs, ensuring a structured and systematic approach to the study's findings.

RESULTS: A total of 259 pharmacist interventions were made, and the results revealed a remarkably high acceptance rate of 98.5% among physicians. The most common intervention (16.21%) involved targeted education to improve medication adherence. Additionally, substantial efforts were directed towards rectifying inappropriate dosage regimens, accounting for 13.51% of DRPs resolved by the pharmacist. Noteworthy interventions also encompassed the identification and management of potential or suspected adverse reactions, comprising 12.35% of the interventions, along with interventions addressing concerns regarding potentially ineffective therapy, which constituted 11.59%.
