Interpretations of nonstress tests by obstetric nurses

Five 20-minute nonstress-test strips were mailed to 1,000 members of NAACOG--the organization for obstetric, gynecologic, and neonatal nurses. The individuals were selected systematically from NAACOG's 10 districts. For the 412 (41%) respondents, at least 84% of the answers concurred on each of the five strips. The majority opinion was taken to be the correct answer. Concurrence with the majority was independent of clinical experience, clinical training, and the extent of present nonstress-test responsibilities. The same five strips were interpreted by obstetricians in a previously reported survey. On a two-point, reactive-nonreactive scale, the sample of obstetric nurses' degree of agreement differed significantly from the sample of physicians' degree of agreement (92 versus 98%) on only one strip.
