title: An ergonomic evaluation of a patient handling device: the elevate and transfer vehicle.
abstract: This study evaluated a Patient Handling Device (PHD) called the Elevate and Transfer Vehicle (ETV). The ETV works on the principle of leverage to transfer a patient from one seated position to another. Three types of product evaluation were used: expert appraisal; user trials; and performance tests. Expert appraisal was conducted by a panel of 11 people including an ergonomist, an industrial designer, two engineers, including one employed as an academic in a School of Mechanical, Manufacturing and Medical Engineering, and seven health professionals. The experts evaluated the ETV using a checklist and group discussions. They generally agreed that the advantages of the ETV tested were it's simplicity, the convenient position to adjust clothing for toileting and the need for only one carer. They noted comfort, security of straps, centre of gravity and manoeuvrability as the main areas for improvement. User trials consisted of nine male and nine female volunteer users assigned to carer/patient pairs. Following a training period, each user subjectively evaluated the ETV by structured interview. User trial results indicated ease of use, prevention of back injuries in carers and minimal body contact were advantages of the ETV. The main problems with using the ETV appeared to be the inadequate 'prop' and straps, the 'jolt' and lack of dignity for the patient. Several critical performance tests were conducted to determine compliance to Australian Standards for design. Areas of non-compliance included strength of frame and static stability. The findings suggest that most of the identified problems of the ETV could be overcome with minor design improvements. The general consensus of participants was to keep the design simple, maintain fast transfers and maintain the position of the patient to enable ease of clothing adjustment for toileting.
