Title: A Comparison of Traditional Paper, Computer Screen, and Computer Printout Interpretation of Electronic Fetal Monitoring (EFM) Tracings
- Identify 3 differences in the visual presentation of EFM tracings related to mode that could affect interpretation.
- State the 2 statistically significant findings reported by the study.
- Discuss a possible implication for nursing care when there is a poor correlation between the visual modes used to present EFM tracings.
Design: Retrospective, descriptive correlational study of EFM tracing records
Setting: The birth center of a large, university medical center
Patients/Participants: The tracing records of 13 patients were collected and reviewed by 5 experienced intrapartum RNs.
Methods: 1½ to 2 hours of tracing was collected for each patient in each mode. Tracings were randomized, and then assessed for uterine activity and fetal heart rate characteristics and assigned an interpretative label every 15 minutes (6-8 assessments per tracing, N=1515).
Results: Crosstabulation using chi-square analysis was performed. A significant difference (p = 0.26) in perception of decelerations was found. More decelerations were identified in the computer screen mode. In addition, there was a significant difference (p = .009) in the interpretative label assigned to the tracing. More tracings were assessed as nonreassuring in the computer screen mode.
Conclusion/Implications for nursing practice: The visual interpretation of FHR tracings is used to assess fetal well-being, the presence of labor, and the adequacy of labor. The accuracy of this interpretation fundamentally affects the care of the pregnant woman and fetus. Most hospitals use some combination of computer-generated FHR images and paper tracing images for bedside interpretation, central surveillance, “down times,” and archiving. The assumption that these modes are interchangeable may be suspect given the findings of this study. Poor correlation between visual modes potentially could lead to inaccurate assessments, inconsistent communication, inappropriate interventions, and increased vulnerability during litigation. More research is needed to either support or refute the equivalence of the three modes when interpreting EFM tracings.
