Objective. To evaluate third-year pharmacy students' ability to effectively design and apply root cause analysis (RCA) to a sentinel event and to analyze student responses for areas of proficiency and deficiency. Methods. This study involved a comprehensive review of RCA key assessments from 82 students in spring 2014. The performance assessments consisted of a review of each student's RCA worksheet and flow diagram as well as the 1-2 page narrative reflection.Results. The majority of students were able to successfully design an RCA, but had challenges with 3 components: fact-finding session, disclosure plan, and a flow diagram. Several students perceived challenges to conducting a formal RCA in certain health care settings, which included assembling an RCA team and gathering relevant facts, a lack of transparency/safe environment within organizations, and creating a plan for multiple/sequential errors. Conclusion. Most students were able to design an RCA process, but encountered difficulty with some components. Students also identified challenges in applying the approach in certain health care arenas.
Background: Venous thromboembolism (VTE) is a major health problem and common cause of morbidity and mortality in hospitalized patients. While trials in both surgical and medically ill patients have demonstrated efficacy and safety of enoxaparin for VTE prophylaxis (VTEP), they failed to adequately represent morbidly obese (body mass index > 40 kg/m 2) patients. Objective: To assess the impact of a weight-adjusted enoxaparin dosing algorithm on anti-factor Xa levels, thrombosis, and bleeding in morbidly obese patients. Methods: A retrospective chart review was conducted, which included morbidly obese patients receiving VTEP with adjusted-dose enoxaparin. Patients received enoxaparin 0.5 mg/kg subcutaneously once or twice daily based on VTE risk. An anti-factor Xa level was drawn 3 to 5 hours after 2 or more consecutive doses. The primary outcome was the percentage of patients achieving target anti-factor Xa levels, defined as 0.2 to 0.6 IU/mL. Secondary outcomes included the incidence of symptomatic VTE and major bleeding. Results: Of the 182 charts reviewed, 141 anti-factor Xa levels from 130 patients met inclusion criteria. The study population was 44% male, and the median body mass index was 45.6 kg/m 2. A total of 120 anti-factor Xa levels (85.1%) were within the target prophylactic range. Sixteen anti-factor Xa levels (11.3%) were below target range, and 5 (3.4%) were above range. The only significant difference among the 3 groups was baseline renal function (P = .035). There were 2 thromboembolic events and 1 major bleed in the study population. Conclusion: A weight-based VTEP dosing strategy for morbidly obese patients is effective without an apparent increase in adverse events.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
