RESUMO
BACKGROUND: Immersive virtual reality (IVR) as a research platform to study human behaviors is an emerging field and may be useful for studying self-care management, especially in the gap between formal healthcare recommendations and day-to-day living. Self-care activities, such as grocery shopping, can be challenging for people with chronic illness. We developed an IVR environment that simulates a real-life grocery store and conducted a usability study to demonstrate the safety and acceptability of IVR as an experimental environment. METHODS: This study was a three-arm randomized control trial involving 24 participants, conducted as a usability study to evaluate aspects of the experimental condition including the effectiveness of a training exposure, the occurrence of undesirable effects associated with IVR, and participants' experiences of realism, immersion, and spatial presence. The experiment, using a head mounted device and handheld controllers, included a 10-minute training exposure, followed by one of three unique 30-minute experimental conditions which exposed participants to different combinations of tasks and stimuli, and a post-experience interview. We measured controller errors, undesirable symptoms associated with IVR, and the perception of realism, immersion, and spatial presence. RESULTS: Participants used controllers effectively to interact within the IVR environment. Hand controller use errors were fewer during the experimental conditions compared to the training exposure. Minimal undesirable IVR symptoms were reported. Presence was rated in the middle range with no significant differences based on experimental condition. Overall, user experience feedback was positive. CONCLUSIONS: We demonstrated that participants could engage in our IVR environment without excessive error or experiencing undesirable effects and confirmed that the virtual experience attained a level of presence necessary to effectively engage in the study. These findings give us confidence that this IVR intervention designed to explore instrumental activities of daily living is safe, effective and provides a credible, controlled simulated community-like setting.

The Advanced Visualization Branch of the National Institute of Nursing Research uses computer technologies to study information visualization in support of self-care management. Advanced technologies, such as immersive virtual reality (IVR), afford researchers the opportunity to study health information visualization where user-initiated information search in visually dense settings precedes acquisition, interpretation, and use. While IVR has broad applicability in healthcare, we chose to target lay people managing chronic disease because of the growing unmet need to translate clinical recommendations into everyday behaviors. To explore how lay people seek, acquire, and interpret health information in everyday settings, we developed an IVR grocery store. In this environment, a person can locate food products, read and compare nutrition labels, and use information to make food selections. The goal of this perspective is to introduce the opportunities afforded by IVR to both present and study health information visualization and to highlight critical design considerations.

Immersive virtual reality computer programs provide new experimental and treatment interventions that hold great promise for nursing. Immersive virtual reality uses sensory cues to represent real-world environments in a way that makes participants feel as if they are in a physical space different from the one in which they currently exist. As the acceptance of immersive virtual reality as a clinical and experimental tool has grown, so has the need to ensure that the context depicted in the environment mirrors both the sensory and the task requirements of the real-world situation. Here, we describe the use of nurse expert key informant group interviews to generate requirements that must be fulfilled in immersive virtual reality environments designed to evoke and engage participants in self-management tasks. An expert panel of four home care nurses participated in three sessions designed to elicit details of common home care challenges, frequency of variation, and typical participants. More than 20 potential scenarios were identified. The design team later used this information to create design requirements for two key scenarios and subsequently develop immersive virtual reality environments for use in research studies, mapping sensory and functional expectations to immersive virtual reality implementations. Challenges in mapping from key informant group findings to requirements are addressed.

OBJECTIVES: To understand requests for nursing Clinical Decision Support (CDS) interventions at a large integrated health system undergoing vendor-based EHR implementation. In addition, to establish a process to guide both short-term implementation and long-term strategic goals to meet nursing CDS needs. MATERIALS AND METHODS: We conducted an environmental scan to understand current state of nursing CDS over three months. The environmental scan consisted of a literature review and an analysis of CDS requests received from across our health system. We identified existing high priority CDS and paper-based tools used in nursing practice at our health system that guide decision-making. RESULTS: A total of 46 nursing CDS requests were received. Fifty-six percent (n=26) were specific to a clinical specialty; 22 percent (n=10) were focused on facilitating clinical consults in the inpatient setting. "Risk Assessments/Risk Reduction/Promotion of Healthy Habits" (n=23) was the most requested High Priority Category received for nursing CDS. A continuum of types of nursing CDS needs emerged using the Data-Information-Knowledge-Wisdom Conceptual Framework: 1) facilitating data capture, 2) meeting information needs, 3) guiding knowledge-based decision making, and 4) exposing analytics for wisdom-based clinical interpretation by the nurse. CONCLUSION: Identifying and prioritizing paper-based tools that can be modified into electronic CDS is a challenge. CDS strategy is an evolving process that relies on close collaboration and engagement with clinical sites for short-term implementation and should be incorporated into a long-term strategic plan that can be optimized and achieved overtime. The Data-Information-Knowledge-Wisdom Conceptual Framework in conjunction with the High Priority Categories established may be a useful tool to guide a strategic approach for meeting short-term nursing CDS needs and aligning with the organizational strategic plan.

High amplitude anthropogenic noise is associated with adverse impacts among a variety of organisms but detailed species-specific knowledge is lacking in relation to effects upon crustaceans. Brown crab (Cancer pagurus), European lobster (Homarus gammarus) and Norway lobster (Nephrops norvegicus) together represent the most valuable commercial fishery in the UK (Defra, 2014). Critical evaluation of literature reveals physiological sensitivity to underwater noise among N. norvegicus and closely related crustacean species, including juvenile stages. Current evidence supports physiological sensitivity to local, particle motion effects of sound production in particular. Derivation of correlative relationships between the introduction of high amplitude impulsive noise and crustacean distribution/abundance is hindered by the coarse resolution of available data at the present time. Future priorities for research are identified and argument for enhanced monitoring under current legislative frameworks outlined.

As health care systems and providers move towards meaningful use of electronic health records, the once distant vision of collaborative patient-centric, interdisciplinary plans of care, generated and updated across organizations and levels of care, may soon become a reality. Effective care planning is included in the proposed Stages 2-3 Meaningful Use quality measures. To facilitate interoperability, standardization of plan of care messaging, content, information and terminology models are needed. This degree of standardization requires local and national coordination. The purpose of this paper is to review some existing standards that may be leveraged to support development of interdisciplinary patient-centric plans of care. Standards are then applied to a use case to demonstrate one method for achieving patient-centric and interoperable interdisciplinary plan of care documentation. Our pilot work suggests that existing standards provide a foundation for adoption and implementation of patient-centric plans of care that are consistent with federal requirements.

OBJECTIVE: A rule-based prototype decision support tool; Braden-scale based Automated Risk-assessment Tool (BART) was developed to test whether pressure ulcer risk scores can be determined automatically based on the documented patient data. METHODS: The data items required for assessing pressure ulcer risk were identified by analyzing the parameter definitions of the Braden scale and by consulting the nurses specialized in pressure ulcer prevention and care. Documentation coverage and formats of the required data was evaluated. The decision rules were developed based on the inputs from the expert nurses, and were implemented as a web-based prototype tool, BART. The agreement rates between nurses and BART on assigning scores to the six Braden-scale parameters were calculated with 39 convenience samples of patient data. RESULTS: Although several items required for the automated decision were not found from the documentation, the majority of the required data items were documented with feasible formats (i.e., coded lists or free text with nominal or numeric values) for algorithmic processing. When evaluated with 39 test cases, BART and the nurses showed varying levels of agreement (from "slight" to "substantial") on assigning scores for the six parameters of the Braden scale. They showed "fair" level of agreement with an "at risk" decision. CONCLUSION: BART has limitations that need to be addressed through future enhancements. However, it demonstrates potential for reuse of documented patient data to automatically populate pressure ulcer risk using the Braden scale.

Dynamic and complex clinical environments present many challenges for effective communication among health care providers. The omission of accurate, timely, easily accessible vital information by health care providers significantly increases risk of patient harm and can have devastating consequences for patient care. An effective nursing handoff supports the standardized transfer of accurate, timely, critical patient information, as well as continuity of care and treatment, resulting in enhanced patient safety. The Brigham and Women's/Faulkner Hospital Healthcare Information Technology Innovation Program (HIP) is supporting the development of a web based nursing handoff tool (NHT). The goal of this project is to develop a "proof of concept" handoff application to be evaluated by nurses on the inpatient intermediate care units. The handoff tool would enable nurses to use existing knowledge of evidence-based handoff methodology in their everyday practice to improve patient care and safety. In this paper, we discuss the results of nursing focus groups designed to identify the current state of handoff practice as well as the functional and data element requirements of a web based Nursing Handoff Tool (NHT).

Representing nursing assessment data in a reusable manner is important as it provides a basis for decision making in patient care. In a previous study, we have extended the ICNP concept model to support representation of nursing assessment data. In this study, we evaluated its potential to support electronic documentation of nursing assessment data and HL7 conformant message generation by mapping it to the HL7 RIM. The semantics represented by the ICNP were completely related to the RIM implying that the ICNP is a good candidate terminology to encode the data with in an electronic documentation system. A few differences between the two models in representing the same semantics suggests that there is value to supporting broad ranges of semantic relations in the ICNP.

One of the challenges hospitals face with in computerizing a documentation system is preparing documentation contents in a way that sufficiently reflects existing best nursing practice while reconciling heterogeneous formats and expressions of the same contents across settings. We have identified a strategy to support analyzing the existing documentation contents collected from various paper forms across Partners HealthCare System (PHS). We introduce the process and the tool that we have developed to support the content preparation efforts.

OBJECTIVES: The purpose of this study was to evaluate the adequacy of the International Classification of Nursing Practice (1) (ICPN) Version 1.0 as a representational model for nursing assessment documentation. DESIGN AND MEASUREMENTS: To identify representational requirements of nursing assessments, the authors mapped key concepts and semantic relations extracted from standardized and local nursing admission assessment documentation forms/templates and inpatient admission assessment records to the ICNP. Next, they expanded the list of ICNP semantic relations with those obtained from the admission assessment forms/templates. The expanded ICNP semantic relations were then validated against the semantic relations identified from an additional set of admission assessment records and a set of 300 randomly selected North American Nursing Diagnosis Association defining characteristic phrases. The concept coverage of the ICNP was evaluated by mapping the concepts extracted from these sources to the ICNP concepts. The UMLS Methathesaurus was then used to map concepts without exact matches to other American Nursing Association (ANA) recognized terminologies. RESULTS: The authors found that along with the 30 existing ICNP semantic relations, an additional 17 are required for the ICNP to function as a representational model for nursing assessment documentation. Eight hundred and five unique assessment concepts were extracted from all sources. Forty-three percent of these unique assessment concepts had exact matches in the ICNP. An additional 20% had matches in the ICNP classified as narrower, broader, or "other." Of the concepts without exact matches in the ICNP, 81% had exact matches found in other ANA recognized terminologies. CONCLUSIONS: The broad concept coverage and the logic-based structure of the ICNP make it a flexible and robust standard. The ICNP provides a framework from which to capture and reuse atomic level data to facilitate evidence-based practice.

Patient assessment provides the basis for identifying patient problems sensitive to nursing care and aligning nursing interventions to promote positive patient outcomes. We mapped the key concepts and attribute relations extracted from a set of initial patient assessment items to the International Classification for Nursing Practice (ICNP). Although we found the coverage of the ICNP not yet complete, we believe that the ICNP does have the potential to represent the nursing assessment data.

We conducted a feasibility study of an innovative Internet-based system, designed to support collaboration between patients and providers around cancer related symptom management. Our objective was to demonstrate the system's potential to enhance communication and clinical decision making between patients and their providers. Considering the high prevalence of cancer related symptoms and their impact on patients' quality of life, enhanced collaboration regarding assessment and treatment could significantly reduce illness burden. Twenty-seven patients with known malignancy and twenty-nine oncology clinicians were interviewed to identify functional requirements for the system. Patients reported the ability, willingness and desire to use a computer to help them manage their cancer related symptoms. Physicians recognized the potential of this system to improve communication and collaboration around symptom management, but voiced concern regarding a potential increased workload. Nurse providers had greater interest in reviewing symptoms online than did their physician counterparts. Patients in this study believe that using an Internet based system to report their cancer related symptoms would improve the quality of the care they receive. Our findings suggest that both patients and clinicians are concerned about the management of cancer related symptoms and would use Internet-based tools if they were shown to improve care.
