Argument identification for arterial branching predications asserted in cardiac catheterization reports.

The language describing coronary vasculature provides a suitable paradigm for research in semantic interpretation of anatomical text. As a pilot project we investigate the possibility of highly accurate retrieval of arterial branching relationships asserted in cardiac catheterization reports. Our methodology relies on the cooperation of underspecified linguistic analysis and structured domain knowledge. The satisfactory results of formal evaluation on both a training and testing set support the promise of this approach.

High-tech homecare infusion therapies.

Dramatic changes in health care delivery have created an increased reliance on ambulatory care. Adults and children increasingly are receiving infusions of intravascular medication or fluid in the home for a wide array of conditions. Several therapies have been adapted to the home, including chemotherapy, BRMs, TPN, blood components, anti-infectives, analgesics, inotropic agents, and investigational drugs. High-technology therapy in the home mandates safe and reliable vascular access to maximize positive outcomes, independence, and self-care; minimize costs and disruption of daily activities and work schedules; and enhance client and family adjustments and satisfaction. Currently, the four main VADs for vascular access are central venous catheters (CVCs), peripherally inserted central catheters (PICCs, implantable infusion ports, and external or implantable ambulatory infusion pumps.

Identification of anatomical terminology in medical text.

We report on an experiment to use the natural language processing tools being developed in the SPECIALIST system to accurately identify terminology associated with the coronary arteries as expressed in coronary catheterization reports. The ultimate goal is to map from any anatomically-oriented medical text to online images, using the UMLS as an intermediate knowledge source. We describe some of the problems encountered when processing coronary artery terminology and report on the results of a formative evaluation of a tool for addressing these problems.

Automatic semantic interpretation of anatomic spatial relationships in clinical text.

A set of semantic interpretation rules to link the syntax and semantics of locative relationships among anatomic entities was developed and implemented in a natural language processing system. Two experiments assessed the ability of the system to identify and characterize physico-spatial relationships in coronary angiography reports. Branching relationships were by far the most common observed (75%), followed by PATH (20%) and PART/WHOLE relationships. Recall and precision scores were 0.78 and 0.67 overall, suggesting the viability of this approach in semantic processing of clinical text.

Formative evaluation of a frame-based model of locative relationships in human anatomy.

The verb structure of narrative text in a gross anatomy textbook was analyzed to identify locative relationships. The 169 locative indicators were organized semantically to construct a frame-based model. The validity and coverage of the model was assessed and compared with the UMLS Semantic Net Relations using a novel test set of 71 indicators. All mapped directly to the frame model, while 60% mapped directly to UMLS.

Personality types of oncology nurses.

Personality type influences the choice of occupation. The breadth of specialty areas within oncology nursing allows for divergent activities and relationships and, thus, the accommodation of different personality characteristics. This exploratory study examined personality types for a convenience sample of oncology nurses predominantly employed in hospitals. According to the personality typology defined by Carl Jung, a person demonstrates a preference among four dimensions, i.e., extraversion/introversion, sensory/intuition, thinking/feeling, and judging/perceiving. The type with the strongest self-selection for these oncology nurses was ISFJ, where feeling is introverted and perception is practical, so that helping others is both a responsibility and a pleasure. The discussion relates the personality types to Jung's theory and their impact in clinical practice. Strengths and weaknesses of each personality type are described.

Immune complexes in hemophilia.

Circulating immune complexes (ICs), assayed by the L1210 enzyme-linked immunoassay, were detected in 48% of patients with hemophilia. A, 50% of patients with von Willebrand's disease, and in none of our patients with hemophilia B. Eighty-five % of the hemophilia A and B patients had mild to moderate disease with only one patient demonstrating a circulating inhibitor. No correlation was found between IC levels and hepatitis B infection, SGOT, disease severity, total quantity of factor VIII or IX infused, time interval from list infusion, or rheumatoid factor positivity. Although the nature of the ICs is not known, the similarity of IC levels between hemophilia A and von Willebrand's disease is discussed with regard to antibodies generated to non-procoagulant portions of the factor VIII molecule.

Changing the role of the nurse in the hematology-oncology outpatient setting.

Changing healthcare economics, advances in technology, and consumer preferences have escalated the growth of outpatient hematology-oncology services and expanded the scope of professional decision making. Currently, 80%-90% of cancer care is delivered in the outpatient setting. Moreover, third-party payers are encouraging an even greater frequency of out-of-hospital hematology-oncology services. Oncology nurses are in key positions to change the outpatient healthcare setting in ways that promote quality care and improved use of professional nursing knowledge and expertise. This article describes a nurse manager's use of Lewinian theory to develop and implement plans for needed change in an outpatient Hematology-Oncology Department.
