Introduction: Factor Xa (fXa) inhibitor reversal for life-threatening bleeding is controversial due to a lack of high-quality evidence. The purpose of this study was to determine the hemostatic efficacy of four-factor prothrombin complex concentrate (4F-PCC) for the reversal of fXa inhibitors compared to warfarin for life-threatening bleeding.

Methods: This was a multicenter, retrospective cohort study at two academic medical centers between January 1, 2014-December 31, 2019, which included patients who presented to the emergency department with a life-threatening bleed necessitating anticoagulation reversal with 4F-PCC.

Introduction: Critically ill patients and their pharmacokinetics present complexities often not considered by consensus guidelines from the American Society of Health-System Pharmacists, the Infectious Diseases Society of America, and the Society of Infectious Diseases Pharmacists. Prior surveys have suggested discordance between certain guideline recommendations and reported infectious disease pharmacist practice. Vancomycin dosing practices, including institutional considerations, have not previously been well described in the critically ill patient population.

Background: The differential diagnosis for thrombocytopenia in critical illness is often extensive. This study was performed to determine the incidence of thrombocytopenia in septic patients undergoing continuous renal replacement therapy (CRRT) versus those not undergoing CRRT.

Objective: The primary outcome of this study was to compare the development of thrombocytopenia, defined as a platelet count ≤ 100 × 10/mm, in septic patients within 5 days of time zero.

Objectives: The objectives of this study were to: 1) determine the association between vasopressor dosing intensity during the first 6 hours and first 24 hours after the onset of septic shock and 30-day in-hospital mortality; 2) determine whether the effect of vasopressor dosing intensity varies by fluid resuscitation volume; and 3) determine whether the effect of vasopressor dosing intensity varies by dosing titration pattern.

Design: Multicenter prospective cohort study between September 2017 and February 2018. Vasopressor dosing intensity was defined as the total vasopressor dose infused across all vasopressors in norepinephrine equivalents.

Objectives: This survey sought to characterize the national prescribing patterns and barriers to the use of thrombolytic agents in the treatment of pulmonary embolism, with a specific focus on treatment during actual or imminent cardiac arrest.

Design: A 19-question international, cross-sectional survey on thrombolytic use in pulmonary embolism was developed, validated, and administered. A multivariable logistic regression was conducted to determine factors predictive of utilization of thrombolytics in the setting of cardiac arrest secondary to pulmonary embolism.

Background: Vancomycin plus piperacillin-tazobactam (VPT) is a commonly used empiric combination of antimicrobials. Recently, studies have demonstrated an increase in acute kidney injury (AKI) associated with combination therapy of VPT. However, the majority of studies required patients to be on VPT for a minimum of 48 to 72 hours to be considered for inclusion and had extended treatment durations longer than most empiric, short course regimens.

Purpose: Attainment of postgraduate year 1 (PGY1) residency positions has become increasingly competitive. Inclusion of clinical knowledge and problem-solving assessments in onsite interviews has increased in recent years. Characterization of these assessments is necessary for applicants to best prepare for interviews and for mentors to provide guidance.

Background: Pharmacodynamic and pathophysiologic changes in critically ill adults receiving cefepime may increase the risk of adverse events.

Research Question: What is the impact of cefepime exposure on neurotoxicity development in critically ill adults with renal dysfunction?

Study Design And Methods: Critically ill adults with creatinine clearance < 60 mL/min who received cefepime for ≥ 48 hours between January 1, 2014 and July 31, 2018 were evaluated for cefepime-associated neurotoxicity (CAN) development. Higher- and lower-dose cefepime exposure groups stratified by moderate (≥ 8 g vs < 8 g in first 48 hours) or severe (≥ 4 g vs < 4 g in first 48 hours) renal dysfunction were compared.

Introduction: Although much is known about the perceived motivating factors and barriers to individuals pursuing postgraduate year-one (PGY1) residency training, determinants for pursuit of further training after PGY1 are unclear.

Methods: Residents at accredited programs were surveyed regarding grit, residency program and resident characteristics, and pursuit of additional post-graduate training (PGT) intentions and behaviors. Two respondent groups were developed: Pursued Additional PGT and Did Not Pursue Additional PGT.

To characterize the practices and perceptions of recent post-graduate year 2 (PGY2) critical care pharmacy (CCP) residents surrounding the completion and publication of their primary research project. Potential factors and perceptions influencing primary research project publication success were identified and incorporated in a validated electronic survey distributed to 2011 and 2012 PGY2 CCP residency program graduates. Among the 94/124 (76%) respondents, 26% had published their research project (67% were first authors; 50% were successful on first submission), while 36% still planned to pursue publication, and 38% had no plans for their manuscript.
