The use of anti-Xa levels for heparin titration showed higher rates of major bleeding complications in vascular surgery patients compared with aPTT monitoring, but no significant difference was identified in this study. Vascular surgery patients with relatively high aPTT to anti-Xa values may have an increased risk of bleeding complications when heparin is titrated based on anti-Xa levels.

Background: Pharmacy residency programs provide research training experiences to residents, and publication is considered an indicator of high-quality research experiences. Objective: This study described attributes of pharmacy residents, residency programs, and residency major research projects and their associations with the outcome of publication in a peer-reviewed journal. Methods: Pharmacy residents who graduated from one academic medical center between 2001 and 2012 were invited to participate via an electronic survey distributed in February 2014. The survey collected attributes of the resident, residency program, and research project. The outcome of publication was self-reported by residents in 2014 and updated in July 2019 using a validated search strategy. Results: This study included 53 resident graduates representing 66 major pharmacy residency projects. Eighteen (27%) projects were published, occurring at an average of 13.8 months after residency graduation. The outcome of publication was more likely for residents with human subjects research experience prior to PGY1 training, residency programs that cultivated resident expertise in Institutional Review Board submission and statistical analysis, and projects with Institutional Review Board approval, a larger number of co-investigators, non-pharmacy co-investigators, and a larger sample size. Conclusion: This cohort of residents, programs, and projects at an academic medical center identified many modifiable attributes that were associated with successful publication of resident research projects. Unfortunately, residency projects rarely used study design features that attenuate bias. Residents and preceptors were perceived as having limited expertise with statistical analysis and database management, which underscores the need to develop research infrastructure to enhance research training for pharmacy students, residents, and preceptors.

The Art and Science of Infusion Nursing BACKGROUND Inpatient use of midline catheters has increased as a strategy to reduce excessive use of central venous access devices (CVADs) and risk of central-line associated bloodstream infections. 1,2 In addition, a midline catheter is recommended for therapy lasting 5 to 14 days, providing a longer catheter dwell time than short peripheral intravenous catheters. Use of midline catheters may remain appropriate for therapy up to 28 days depending on patient vasculature, patient preference, and documented catheter function during use. 3,4 However, the risk of symptomatic catheter-related thrombosis (CRT) with midline catheters (0%-12%) may be similar or higher than CVADs (up to 10%). 5,6 Midline catheters are inserted into basilic, brachial, or cephalic veins and terminate at or below the axilla, with a typical length of 8 to 20 cm. 4 This placement into smaller veins with lower flow rates than central veins may contribute to the risk of CRT observed for midline catheters. 7 To directly address this issue, new device technology has emerged to reduce thrombus accumulation on the surface of the midline ABSTRACTThe use of midline catheters has increased to reduce excessive use of central venous access devices, and additional data on midline catheter complications are needed. This study aimed to describe midline catheter complications among hospitalized patients. This retrospective study included a random sample of 300 hospitalized patients with a midline catheter insertion in 2019. The primary outcome was a composite end point of 8 complications: occlusion, bleeding at insertion site, infiltration/extravasation, catheter-related thrombosis, accidental removal, phlebitis, hematoma, and catheter-related infection. Midline catheter failure was defined as removal prior to the end of therapy due to complications. Among 300 midline catheters, the incidence of the composite end point of 1 or more midline complications was 38% (95% confidence interval, 33%-44%). Complications included occlusion (17.0%), bleeding at insertion site (12.0%), infiltration/extravasation (10.0%), catheter-related thrombosis (4.0%), accidental removal (3.0%), phlebitis (0.3%), hematoma (0.3%), and catheter-related infection (0.3%). Midline catheter failure occurred in 16% of midline catheters (n = 48) due to infiltration/extravasation (n = 27), accidental removal (n = 10), catheter-related thrombosis (n = 9), occlusion (n = 4), and catheter-related infection (n = 1). Three catheters had 2 types of failure. The most common complications of occlusion and bleeding rarely resulted in midline catheter failure. The most common causes of midline catheter failure were infiltration/extravasation, accidental removal, and catheter-related thrombosis.

This study aimed to develop a definition of vasoplegia that reliably predicts clinical outcomes. Vasoplegia was evaluated using data from the electronic health record for each 15-minute interval for 72 hours following cardiopulmonary bypass. Standardized definitions considered clinical features (systemic vascular resistance [SVR], mean arterial pressure [MAP], cardiac index [CI], norepinephrine equivalents [NEE]), threshold strategy (criteria occurring in any versus all measurements in an interval), and duration (criteria occurring over multiple consecutive versus separated intervals). Minor vasoplegia was MAP < 60 mm Hg or SVR < 800 dynes⋅sec⋅cm −5 with CI > 2.2 L/min/m 2 and NEE ≥ 0.1 µg/kg/min. Major vasoplegia was MAP < 60 mm Hg or SVR < 700 dynes⋅sec⋅cm −5 with CI > 2.5 L/min/m 2 and NEE ≥ 0.2 µg/kg/min. The primary outcome was incidence of vasoplegia for eight definitions developed utilizing combinations of these criteria. Secondary outcomes were associations between vasoplegia definitions and three clinical outcomes: time to extubation, time to intensive care unit discharge, and nonfavorable discharge. Minor vasoplegia detected anytime within a 15-minute period (MINOR_ANY_15) predicted the highest incidence of vasoplegia (61%) and was associated with two of three clinical outcomes: 1 day delay to first extubation (95% CI: 0.2 to 2) and 7 day delay to first intensive care unit discharge (95% CI: 1 to 13). The MINOR_ANY_15 definition should be externally validated as an optimal definition of vasoplegia. ASAIO

Human 4-factor prothrombin complex concentrate (4F-PCC) may reduce blood loss during surgery. This case series described perioperative outcomes among 9 patients who refused standard allogeneic blood transfusion, underwent complex cardiac surgery with aortic involvement, and received intraoperative 4F-PCC. Additional intraoperative cointerventions included protamine (n = 9), aminocaproic acid (n = 8), fibrinogen concentrate (n = 6), desmopressin (n = 6), factor VIIa (n = 2), and tranexamic acid (n = 1). Outcomes included postoperative death (n = 1), major postoperative bleeding (n = 1), deep vein thrombosis (n = 2), and ischemic stroke (n = 1). When standard allogeneic blood transfusion is refused, viable hemostasis can be obtained using 4F-PCC during complex cardiac surgeries with a high risk of bleeding.
