This article presents the findings of a study on the use of an electronic portfolio (EP) in 16 elementary classrooms across Canada. Using a mixed-methods approach, data were collected to understand how teachers used EPs in their classrooms, to what extent they integrated the EP into their practice, and the factors influencing their use. Using expectancy theory, findings indicate that low implementers experienced significant technical obstacles and/or were reluctant to change their established practices, whereas high implementers reported feeling supported by their administration, experiencing growth in their teaching practice, and using more pedagogical practices that support self-regulated learning as a result of the scaffolding provided by the software.
We found no difference in mortality between an nurse practitioner-staffed medical ICU and a resident-staffed physician medical ICU. Our study adds further evidence that advanced practice providers can render safe and effective ICU care.
Ventilator-associated pneumonia is a common nosocomial infection that results in both negative patient outcomes and increased health care costs. Recently, many efforts have been targeted at ventilator-associated pneumonia prevention, including the practice of subglottic secretion aspiration. Six randomized control studies examining the effectiveness of subglottic secretion aspiration in the prevention of ventilator-associated pneumonia were reviewed for this article. Results consistently show that subglottic secretion aspiration significantly reduces the incidence of ventilator-associated pneumonia in a variety of patient populations. Despite these findings, this practice is limited in clinical settings. This clinical practice should be implemented in individuals requiring mechanical ventilation to reduce the incidence of ventilator-associated pneumonia.
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.
