The patient roller is the most effective device for reducing patient transfer forces, benefiting healthcare workers. Heavier patients and gurney-to-bed transfers require more force, highlighting the need for assistance.

Area of Science:

  • Occupational Safety and Health
  • Biomechanics
  • Ergonomics

Background:

  • Healthcare workers performing patient transfers are at high risk for back injuries.
  • Patient transfers between beds and gurneys involve strenuous pulling motions requiring significant physical strength.
  • Evaluating the efficiency of patient transfer devices is crucial for injury prevention.

Purpose of the Study:

  • To compare the efficiency of three commercially available patient transfer devices: a patient roller, a patient shifter, and a draw sheet.
  • To quantify the forces required for patient transfers using different devices.
  • To identify factors influencing the forces needed during patient transfers.

Main Methods:

  • Fifteen participants (101-240 lbs) were transferred between a bed and a gurney using each device.

Related Experiment Videos

  • Force measurements were recorded using force scales attached to the transfer devices.
  • Ten transfers were conducted per participant for each device.

    • Main Results:

    • The patient roller significantly reduced the forces required for patient transfers compared to the patient shifter and draw sheet.
    • Transfers from a gurney to a bed were more demanding than bed-to-gurney transfers across all devices.
    • Heavier participants required greater forces for transfers, regardless of the device used.

    Conclusions:

    • The patient roller is the most efficient device for minimizing physical strain during patient transfers.
    • Linear equations can estimate transfer forces based on patient weight, transfer direction, and device type.
    • Findings can aid occupational therapists in rehabilitating injured healthcare workers and inform best practices for patient handling to prevent injuries.
