Nurses' perspectives on problems of hospitalized PCP patients: implications for the development of a nursing taxonomy.

The phenomena of interest in nursing informatics research are the data, information and knowledge related to nursing. This study presents nurses' perspectives on the problems of patients hospitalized for Pneumocystis carinii pneumonia from four data sources: nurse interview, intershift report, care plan, and nurses' notes. Even within this narrowly specified sample, patient problems showed variation across sources of data. The results of this study demonstrate the difficulties inherent in developing a nursing taxonomy when there is not consensus about the relevant data for nursing within a specific patient sample. Although existing information technology is capable of processing large volumes of nursing data, the lack of a common taxonomy limits the usefulness of the technology for documentation of care and decision support applications.
