Acquiring sepsis competencies through simulation-based learning bundle during intermediate care unit internship.

ABSTRACT: Intermediate care units (ImCUs) have been shown as appropriate units for the management of selected septic patients. Developing specific protocols for residents in training may be useful for their medical performance. The objective of this study was to analyze whether a simulation-based learning bundle is useful for residents while acquiring competencies in the management of sepsis during their internship in an ImCU.A prospective study, set in a tertiary-care academic medical center was performed enrolling residents who performed their internship in an ImCU from 2014 to 2017. The pillars of the simulation-based learning bundle were sepsis scenario in the simulation center, instructional material, and sepsis lecture, and management of septic patients admitted in the ImCU. Each resident was evaluated in the beginning and at the end of their internship displaying a sepsis-case scenario in the simulation center. The authors developed a sepsis-checklist that residents must fulfill during their performance which included 5 areas: hemodynamics (0-10), oxygenation (0-5), antibiotic therapy (0-9), organic injury (0-5), and miscellaneous (0-4).Thirty-four residents from different years of residency and specialties were evaluated. The total median score (interquartile range) increased significantly after training: 12 (25) vs 23 (16), P = .001. First-year residents scored significantly lower than older residents at baseline: 10 (14) vs 14.5 (19), P = .024. However, the performance at the end of the training period was similar in both groups: 21.5 (11) vs 23 (16), P = 1.000. Internal Medicine residents scored significantly higher than residents from other specialties: 18 (17) vs 10.5 (21), P = .007. Nonetheless, the performance at the end of the training period was similar in both groups: 24.5 (9) vs 22 (13), P = 1.000.Combining medical simulation with didactic lectures and a rotation in an ImCU staffed by hospitalists seems to be useful in acquiring competencies to manage critically ill patients with sepsis. We designed a checklist to assure an objective evaluation of the performance of the residents and to identify those aspects that could be potentially improved.

Prognostic factors and prevention of radioembolization-induced liver disease.

UNLABELLED: Radioembolization (RE)-induced liver disease (REILD) has been defined as jaundice and ascites appearing 1 to 2 months after RE in the absence of tumor progression or bile duct occlusion. Our aims were to study the incidence of REILD in a large cohort of patients and the impact of a series of changes introduced in the processes of treatment design, activity calculation, and the routine use of ursodeoxycholic acid and low-dose steroids (modified protocol). Between 2003 and 2011, 260 patients with liver tumors treated by RE were studied (standard protocol: 75, modified protocol: 185). REILD appeared only in patients with cirrhosis or in noncirrhosis patients exposed to systemic chemotherapy prior to RE. Globally, the incidence of REILD was reduced in the modified protocol group from 22.7% to 5.4% and the incidence of severe REILD from 13.3% to 2.2% (P<0.0001). Treatment efficacy was not jeopardized since 3-month disease control rates were virtually identical in both groups (66.7% and 67.2%, P=0.93). Exposure to chemotherapy in the 2-month period following RE and being treated by the standard protocol were independent predictors of REILD among noncirrhosis patients. In cirrhosis, the presence of a small liver (total volume<1.5 L), an abnormal bilirubin (>1.2 mg/dL), and treatment in a selective fashion were independently associated with REILD. CONCLUSION: REILD is an uncommon but relevant complication that appears when liver tissue primed by cirrhosis or prior and subsequent chemotherapy is exposed to the radiation delivered by radioactive microspheres. We designed a comprehensive treatment protocol that reduces the frequency and the severity of REILD.

Liver disease induced by radioembolization of liver tumors: description and possible risk factors.

BACKGROUND: To the authors' knowledge, liver damage after liver radioembolization with yttrium90-labeled microspheres has never been studied specifically. METHODS: Using a complete set of data recorded prospectively among all patients without previous chronic liver disease treated by radioembolization at the authors' institution from September 2003 to July 2006, patterns of liver damage were identified and possible risk factors were analyzed. RESULTS: In all, 20% of patients developed a distinct clinical picture that appeared 4 to 8 weeks after treatment and was characterized by jaundice and ascites. Veno-occlusive disease was the histologic hallmark observed in the most severe cases. This form of sinusoidal obstruction syndrome was not observed among patients who never received chemotherapy or in those in whom a single hepatic lobe was treated. Relevant to treatment planning, a possible risk factor was a higher treatment dose in relation to the targeted liver volume. A transjugular intrahepatic stent shunt improved liver function in 2 patients with impending liver failure, although 1 of them eventually died from it. CONCLUSIONS: Radioembolization of liver tumors, particularly after antineoplastic chemotherapy, may result in an uncommon but potentially life-threatening form of hepatic sinusoidal obstruction syndrome that presents clinically with jaundice and ascites.
