A biomechanical and ergonomic evaluation of patient transferring tasks: bed to wheelchair and wheelchair to bedA Garg et al. Ergonomics. 1991 Mar. Show
AbstractA laboratory study was conducted in an effort to reduce back stress for nursing personnel while performing the patient handling tasks of transferring the patient from bed to wheelchair and wheelchair to bed. These patient handling tasks were studied using five manual techniques and three hoist-assisted techniques. The manual techniques involved one-person and two-person transfers. One manual technique involved a two-person lift of the patient under the arms; the others used a rocking and pulling action and included the use of assistive devices (a gait belt using a two-person transfer, a walking belt with handles using a one-person and a two-person transfer, and a patient handling sling with cutout areas to allow for a hand grip (Medesign) for a one-person transfer). The three mechanical hoists were Hoyer, Trans-Aid and Ambulift. Six female nursing students with prior patient transfer experience served both as nurses and as passive patients. Static biomechanical evaluation showed that pulling techniques, as compared to lifting the patient, required significantly lower hand forces and produced significantly lower erector spinae and compressive forces at the L5/S1 disc (P greater than or equal to 0.01). Shear force, trunk moments and the percentage of females who were capable of performing the transfers (based on static strength simulation) also favoured pulling methods. Perceived stress ratings for the shoulder, upper back, lower back and whole body were lower for pulling methods than those for lifting the patient (P less than or equal to 0.01). Patients found the pulling techniques, with the exception of when using the gait belt, felt more comfortable and more secure than the lifting method (P less than or equal to 0.01). However, a number of subjects believed that the patient handling sling (Medesign) and the walking belt with one person making the transfer would not work for those patients who could not bear weight and those who were heavy, contracted or combative. A walking belt with two persons was the preferred manual method. Two out of three hoists (Hoyer lift and Trans-Aid) were perceived by the nurses to be as physically stressful as manual methods. Patients found these two hoists to be more uncomfortable and felt less secure than with three of the five manual methods (one- and two-person walking belts and Medesign). Ambulift was found to be the least stressful, the most comfortable, and the most secure among all eight methods. Pulling techniques and hoists took significantly longer amounts of time to make the transfer than manually lifting the patient (P less than or equal to 0.01). The two-person walking belt using a pulling technique and Ambulift are recommended for transferring patients from bed to wheelchair and wheelchair to bed. A large-scale field study is needed to verify these recommendations. Similar articles

Which action should the nurse take to move the patient up in bed with a mechanical lift?Lock the base lever in the open position when moving the mechanical lift.. Raise the mechanical lift so that the patient is six inches off the mattress.. Keep the wheels of the mechanical lift locked throughout the procedure.. Ensure the patients feet are guarded when sitting on the mechanical lift.. When preparing to transfer a patient from the bed to a chair the nurse should?When preparing to safely transfer a patient from a bed to a wheelchair, the nurse should first:. Determine the patient's arm strength.. Assess the patient's weight-bearing ability.. Assess the patient's willingness to cooperate.. Decide upon the most appropriate transfer method.. When transferring a patient from a bed to a chair the nurse should use which of the following to avoid back injury?Hold a strong abdominal contraction. Position your body close to your loved one to decrease strain on your back. Before movement, contract your abdominal muscles to protect your back. Use your knees and your lower body during transfer to decrease strain on your back.
