Nurses accurately estimate backrest elevation angles, crucial for preventing pneumonia in ventilated patients. Despite accurate estimates, this practice is not consistently followed, indicating other barriers exist.

Area of Science:

  • Nursing Care
  • Patient Safety
  • Critical Care Medicine

Background:

  • Patient positioning is vital in nursing care, impacting patient outcomes.
  • Elevating the head of the bed (30-45 degrees) is recommended by the CDC to prevent nosocomial pneumonia in mechanically ventilated patients.
  • Higher backrest elevation is not consistently implemented in critical care settings, potentially due to inaccurate angle estimations by nurses.

Purpose of the Study:

  • To assess the discrepancy between nurses' estimated bed angles and actual measured angles.
  • To investigate the correlation between nurses' demographic characteristics and their accuracy in estimating bed angles.

Main Methods:

  • A convenience sample of 67 nurses participated.
  • Nurses estimated three pre-selected bed angles.

  • Demographic data were collected and analyzed alongside angle estimations and measurements.

    • Main Results:

    • Nurses demonstrated high accuracy in estimating bed angles (correlation of 0.8488).
    • No significant relationship was found between demographic factors (sex, age, experience, education, position) and estimation accuracy.

    Conclusions:

    • Nurses possess the ability to accurately estimate backrest elevation.
    • The findings suggest that inaccurate angle estimation is not the primary reason for the underutilization of recommended backrest elevation practices.
