Impact of the Medication Shortages on Psychiatric Patients: Exploring the Consequences of Lorazepam Injection Scarcity.

Objective: This study reviewed the cases of 13 patients in a psychiatric hospital during the 2022 lorazepam injection shortage in the United States (US). The objective was to determine if there were any patterns to the management of the medication shortage of an essential psychiatric medication at a psychiatric hospital. Methods: A retrospective review of eligible patients who had an order for lorazepam injection prescribed as needed (PRN) between July and October 2022 were divided into, and compared between, two groups: those who had orders permitting continued PRN administration of the medication and those who were discontinued. Results: No negative behavioral issues were seen in the patients who had their doses discontinued. Conclusion: The absence of negative psychiatric consequences suggests that either nonpharmacotherapeutic interventions were alternatively stabilizing or that the standing PRN orders for lorazepam injection were not needed for these patients. A proactive emergency management plan to address critical medication shortages has become an increasingly necessary contingency and would have been appropriate for use during this national shortage.

Utilizing a Human-Computer Interaction Approach to Evaluate the Design of Current Pharmacogenomics Clinical Decision Support.

A formal assessment of pharmacogenomics clinical decision support (PGx-CDS) by providers is lacking in the literature. The objective of this study was to evaluate the usability of PGx-CDS tools that have been implemented in a healthcare setting. We enrolled ten prescribing healthcare providers and had them complete a 60-min usability session, which included interacting with two PGx-CDS scenarios using the "Think Aloud" technique, as well as completing the Computer System Usability Questionnaire (CSUQ). Providers reported positive comments, negative comments, and suggestions for the two PGx-CDS during the usability testing. Most provider comments were in favor of the current PGx-CDS design, with the exception of how the genotype and phenotype information is displayed. The mean CSUQ score for the PGx-CDS overall satisfaction was 6.3 ± 0.95, with seven strongly agreeing and one strongly disagreeing for overall satisfaction. The implemented PGx-CDS at our institution was well received by prescribing healthcare providers. The feedback collected from the session will guide future PGx-CDS designs for our healthcare system and provide a framework for other institutions implementing PGx-CDS.

Rapid onset vancomycin-induced thrombocytopenia confirmed by vancomycin antibody test.

We report a case of vancomycin-induced thrombocytopenia (VIT) with rapid onset after re-exposure to vancomycin. A 58-year-old man with cellulitis was initiated on vancomycin. Approximately 1 hour into the vancomycin infusion, the patient developed an infusion-related reaction. Vancomycin infusion was stopped. A complete blood count obtained 4 hours after discontinuation of the vancomycin infusion revealed a platelet count of 31 ×10-9/L. Investigations ruled out likely causes of thrombocytopenia. VIT was diagnosed based on clinical symptoms and confirmed with drug-dependent platelet antibody testing. Without complications, platelet counts recovered within 7 days after discontinuation of vancomycin. No correlation between vancomycin level and VIT was observed.
