Weight-bearing in Trauma Surgery (WiTS) Study: A national survey of UK Trauma & Orthopaedic multidisciplinary health professionals

Weight-bearing (WB) status following a fracture or surgical fixation is an important determinant of the mechanical environment for healing. In order for healthcare professionals to communicate and understand the extent of bearing weight through a limb, clear terminology must be used. There is widespread variation in the usage and definitions of WB terminology in the literature and clinical practice. This study sought to define the understanding and extent of variation across the United Kingdom.A nationwide online survey of UK-based Trauma & Orthopaedic (T&O) multidisciplinary healthcare professionals was conducted. Participants answered seven questions assessing their usage and understanding of various WB terminology.A total of 707 responses were received: 48% by doctors, 32% by physiotherapists, 13% by occupational therapists and 7% from other healthcare professionals. In terms of understanding of WB terminology with respect to percentage body weight (BW), 89% of respondents interpret 'full WB' as 100% BW, 97% interpret 'non WB' as 0% BW, 80% interpret 'partial WB' as 50% BW, and 89% interpret 'touch/toe-touch WB' as 10% or 20% BW. There were statistically significant differences between the responses of doctors and therapists for these four terms, with doctors tending to give higher %BW values. 'Protected WB' and 'WB as tolerated' had less consensus and more variability in responses. The majority (68%) of respondents do not usually quantify terminology such as 'partial WB' with a value, and 94% agreed that standardisation of WB terminology would improve communication amongst professionals.This study provides evidence of the substantial variation in the understanding of WB terminology amongst healthcare professionals, which likely results in ambiguous rehabilitation advice. Existing literature has shown that patients struggle to comply with terms such as 'partial weight-bearing'. We recommend consensus within the T&O multidisciplinary community to standardise and define common weight-bearing terminology.
