CONTEXT To ensure interpretability and replicability of clinical experiments, methods must be adequately explicit and should elicit the same decision from different clinicians who comply with the study protocol. OBJECTIVE The objective of this study was to determine whether clinician compliance with protocol recommendations exceeds 90%. DESIGN We(More)
Although informatics is an important area of nursing inquiry and practice, few scholars have articulated the philosophical foundations of the field or how these translate into practice including the often-cited data, information, knowledge, and wisdom (DIKW) framework. Data, information, and knowledge, often approached through postpositivism, can be(More)
OBJECTIVE To characterize the clinical course, therapies, and outcomes of children with fatal and near-fatal asthma admitted to pediatric intensive care units (PICUs). STUDY DESIGN This was a retrospective chart abstraction across the 8 tertiary care PICUs of the Collaborative Pediatric Critical Care Research Network (CPCCRN). Inclusion criteria were(More)
Although pediatric intensivists claim to embrace lung protective ventilation for acute lung injury (ALI), ventilator management is variable. We describe ventilator changes clinicians made for children with hypoxemic respiratory failure, and evaluate the potential acceptability of a pediatric ventilation protocol. This was a retrospective cohort study(More)
OBJECTIVE The aim of this study was to assess, using a Web-based format, third-year medical students' pediatric knowledge and perceptions of game playing with faculty facilitation compared with self-study computerized flash cards. METHODS This study used a repeated-measures experimental design with random assignment to a game group or self-study group.(More)
Clinical decision support systems (CDS) can interpret detailed treatment protocols for ICU care providers. In open-loop systems, clinicians can decline protocol recommendations. We capture their reasons for declining as part of ongoing, iterative protocol validation and refinement processes. Even though our protocol was well-accepted by clinicians overall,(More)
The Arden Syntax is an HL7 standard language for representing medical knowledge as logic statements. Despite nearly 2 decades of availability, Arden Syntax has not been widely used. This has been attributed to the lack of a generally available compiler to implement the logic, to Arden's complex syntax, to the challenges of mapping local data to data(More)
This paper is the report of the first phase of a case study from the University of Utah to help students and faculty integrate electronic information management into the nursing curriculum. Cerner AES, a live-production clinical information system with an academic overlay, has been implemented into the first semester of an undergraduate nursing program. A(More)
This paper proposes a series of techniques to be used in teaching database design. Common ERD notations are discussed. The authors developed an ERD notation, adapted from the Unified Modeling Language, which facilitates student learning of the database design process. The paper presents a specific step by step process for representing the ERD components as(More)
Paper-based clinical practice standards usually pertain to a single diagnosis or clinical condition. When a computerized provider order entry system applies multiple paper-based practice standards to one patient, it generates an order list containing redundant orders. Nurses respond to redundant orders on the basis of their level of nursing expertise with(More)
