Testing the generalizability of the ISO model for nursing diagnoses.

The purpose of this study was to explore whether the ISO reference terminology model for nursing diagnoses could be generalized to the MDS data set that, like nursing terminologies standardizes expressions of the concepts within and relevant to the domain of nursing practice. We first constructed paraphrased expressions of the rubrics from the data set. Next we dissected those expressions into the reference model domains of focus and judgment, recorded any qualifiers required for either domain, and semantic links required to represent associative relations. Our findings demonstrate that the ISO model for nursing diagnoses is generalizable to the MDS data set, however expansions to the model are required if the model is to be used to represent objects rather than terms.

A data-driven approach for extracting "the most specific term" for ontology development.

We present a data-driven approach to extract the "most specific" terms relevant to an ontology of functioning, disability and health. The algorithm is a combination of statistical and linguistic approaches. The statistical filter is based on the frequency of the content words in a given text string; the linguistic heuristic is an extension of existing algorithms but goes beyond noun phrases and is formulated as a "complete syntactic node". Thus, it can be applied to any syntactic node of interest in the particular domain. Two test sets were marked by three experts. Test set 1 is a well-constructed text from pain abstracts; test set 2 is actual medical reports. Results are reported as recall, precision, F-score and rate of valid terms in false positives. A limitation of the current research is the relatively small test set.

Development of user-centered interfaces to search the knowledge resources of the Virginia Henderson International Nursing Library.

This poster describes the development of user-centered interfaces in order to extend the functionality of the Virginia Henderson International Nursing Library (VHINL) from library to web based portal to nursing knowledge resources. The existing knowledge structure and computational models are revised and made complementary. Nurses' search behavior is captured and analyzed, and the resulting search models are mapped to the revised knowledge structure and computational model.

FIM score, FIM efficiency, and discharge disposition following inpatient stroke rehabilitation.

The Functional Independence Measure (FIM) is a widely accepted scale used to measure the functional abilities of patients undergoing rehabilitation. Scores at the extremes of this scale correlate with discharge disposition, while midrange scores are less well understood. This study evaluated the rate of FIM change with time ("efficiency"), admission and discharge FIM scores, and discharge disposition of 748 patients who underwent stroke inpatient rehabilitation. Patients with low scores at admission or discharge were likely to be discharged to a facility (63% and 78%, respectively), and those with high scores at admission or discharge almost always returned home (88% and 81%, respectively). Those with midrange scores at admission were more likely to return home (62%) than those with similar scores at discharge (33%). Greater FIM efficiency scores were associated with home discharge. Findings provide insight into discharge planning for stroke patients and indicate the need for more detailed evaluation of the midrange group.
