Patient participation: a concept analysis.

The purpose of this paper is to present an in-depth analysis of the concept of patient participation. The analysis was undertaken using the method described by Walker and Avant. Patient participation is defined and the critical attributes are identified. Model, borderline and contrary cases illustrate what the concept is and is not. The meaning of patient participation is compared with patient partnership, patient collaboration and patient involvement, three related cases. The antecedents and consequences of patient participation are investigated to further refine the critical attributes. Empirical referents are illuminated. The value of concept analysis in relation to precise communication, critical thinking and the advancement of the knowledge base of nursing is discussed.

Reimbursement for carotid stenting: unique challenges for medical centers and physicians.

Carotid artery stenting has been identified as an important therapeutic option for patients with atherosclerotic occlusive disease of the extracranial carotid artery. While the preferred application of this technology remains an area of active clinical investigation and its optimal role may continue to evolve, a preponderance of opinion supports its present application in carefully selected patients. Enabling the introduction of this technology into the broader patient community mandated a consensus between a large number of specialty societies and the Centers for Medicare and Medicaid Services to define both currently acceptable procedures to be performed and appropriate clinical criteria for its suitable application. This report reviews the collaborative process, which evolved to achieve this consensus and the current guidelines for procedural coding, facility accreditation, and reimbursement for carotid artery stenting. Related requirements for Medicare coverage of patients in clinical trials and registries are also discussed.

The next generation of literature analysis: integration of genomic analysis into text mining.

Text-mining systems are indispensable tools to reduce the increasing flux of information in scientific literature to topics pertinent to a particular interest in focus. Most of the scientific literature is published as unstructured free text, complicating the development of data processing tools, which rely on structured information. To overcome the problems of free text analysis, structured, hand-curated information derived from literature is integrated in text-mining systems to improve precision and recall. In this paper several text-mining approaches are reviewed and the next step in development of text-mining systems, which is based on a concept of multiple lines of evidence, is described: results from literature analysis are combined with evidence from experiments and genome analysis to improve the accuracy of results and to generate additional knowledge beyond what is known solely from literature.

Gene name ambiguity of eukaryotic nomenclatures.

MOTIVATION: With more and more scientific literature published online, the effective management and reuse of this knowledge has become problematic. Natural language processing (NLP) may be a potential solution by extracting, structuring and organizing biomedical information in online literature in a timely manner. One essential task is to recognize and identify genomic entities in text. 'Recognition' can be accomplished using pattern matching and machine learning. But for 'identification' these techniques are not adequate. In order to identify genomic entities, NLP needs a comprehensive resource that specifies and classifies genomic entities as they occur in text and that associates them with normalized terms and also unique identifiers so that the extracted entities are well defined. Online organism databases are an excellent resource to create such a lexical resource. However, gene name ambiguity is a serious problem because it affects the appropriate identification of gene entities. In this paper, we explore the extent of the problem and suggest ways to address it. RESULTS: We obtained gene information from 21 organisms and quantified naming ambiguities within species, across species, with English words and with medical terms. When the case (of letters) was retained, official symbols displayed negligible intra-species ambiguity (0.02%) and modest ambiguities with general English words (0.57%) and medical terms (1.01%). In contrast, the across-species ambiguity was high (14.20%). The inclusion of gene synonyms increased intra-species ambiguity substantially and full names contributed greatly to gene-medical-term ambiguity. A comprehensive lexical resource that covers gene information for the 21 organisms was then created and used to identify gene names by using a straightforward string matching program to process 45,000 abstracts associated with the mouse model organism while ignoring case and gene names that were also English words. We found that 85.1% of correctly retrieved mouse genes were ambiguous with other gene names. When gene names that were also English words were included, 233% additional 'gene' instances were retrieved, most of which were false positives. We also found that authors prefer to use synonyms (74.7%) to official symbols (17.7%) or full names (7.6%) in their publications. CONTACT: lifeng.chen@dbmi.columbia.edu
