OBJECTIVES: We aimed to summarize the most significant and impactful publications describing the pharmacotherapeutic care of critically ill patients in 2023. DATA SOURCES: PubMed/MEDLINE and the Clinical Pharmacy and Pharmacology Pharmacotherapy Literature Update. STUDY SELECTION: Randomized controlled trials and prospective studies of adult critically ill patients assessing a pharmacotherapeutic intervention and reporting clinical endpoints published between January 1, 2023, and December 31, 2023, were eligible for inclusion in this article. DATA EXTRACTION: Articles from a systematic search and the Clinical Pharmacy and Pharmacology Pharmacotherapy Literature Update were included. An a priori defined three-round modified Delphi process was employed to achieve consensus on the most impactful publications based on the following considerations: 1) overall contribution to scientific knowledge and 2) novelty to the literature. DATA SYNTHESIS: The systematic search and Clinical Pharmacy and Pharmacology Pharmacotherapy Literature Update returned a total of 1202 articles, of which 1164 were excluded. The remaining 38 articles underwent a three-round modified Delphi process. In each round, articles were independently scored based on overall contribution to scientific knowledge and novelty to the literature. Included articles are summarized and their impact discussed. Article topics included hydrocortisone for severe community-acquired pneumonia, inhaled amikacin for prevention of ventilator-associated pneumonia, methylene blue for septic shock, restrictive vs. liberal fluid management for sepsis-induced hypotension, andexanet alfa for major bleeding associated with factor Xa inhibitors, and early administration of four-factor prothrombin complex concentrate in patients with trauma at risk for massive transfusion. CONCLUSIONS: This review provides a summary and perspective on the potential impact of the most relevant articles in 2023 describing advances in the pharmacotherapeutic care of critically ill patients.

Objectives: Refractory septic shock is associated with high morbidity and mortality. Hydroxocobalamin is used to treat postoperative vasoplegia; however, data supporting its use in the setting of refractory septic shock is limited and restricted to case reports. This study evaluates the effect of hydroxocobalamin on mean arterial pressure and vasopressor requirements in a series of patients with refractory septic shock. Design: Single-center, retrospective analysis. Setting: Urban, tertiary-care ICU. Patients: Adult ICU patients with refractory septic shock treated with hydroxocobalamin between August 2018 and January 2020. Interventions: Hydroxocobalamin 5 g IV infusion. MEASUREMENTS AND MAIN RESULTS: Twenty-six patients were included for the analysis. Administration of hydroxocobalamin was associated with an increase in mean arterial pressure at 1, 6, and 24 hours postdose (+16.3, +14.3, and +16.3 mm Hg, respectively; p < 0.001). Increase in mean arterial pressure from baseline remained statistically significant when controlling for sex, age, and comorbid conditions. There was no change in the norepinephrine equivalents patients required 1 hour following hydroxocobalamin administration, but a statistically significant decrease in norepinephrine equivalent was observed at 6 and 24 hours postdose (p < 0.001). Conclusions: Hydroxocobalamin provides sustained hemodynamic benefit at 24 hours in patients with refractory septic shock.
