Nurse anesthesia research: a follow-up study

We describe a follow-up study comparing nurse anesthesia research in the 1990s with findings of a previous study. Research reported in the AANA journal in 1995 and 1996 (n = 38 studies) was compared with the earlier description of research from 1985-1986 (n = 18) and 1975-1976 (n = 14) periods. The amount of research published in the Journal has increased steadily, with a stable focus on clinical practice. In addition, there has been an increase in educational and safety-related research reported. In an attempt to locate research published in other nursing and medical journals, we found and reviewed additional articles (n = 28) authored or coauthored by CRNAs during the 1995-1996 period. By the 1990s, all studies demonstrated at least 1 indicator of theoretical orientation. Convenience samples of hospitalized patients were the most common type of sample. As in the earlier study, there was minimal reporting on reliability and validity of data and the psychometric evaluation of instruments. Recommendations include increased emphasis on methodological studies, multisite studies, programs of research, and collaboration among CRNAs, nurses in other specialties, and people in other disciplines.
