Talking about walking: lack of shared understanding of common mobility terms among different healthcare professional groups.

Australian studies suggest a lack of consensus in interpreting mobility recommendations, particularly affecting the terms "supervision" and "stand by assistance", was common and a contributing factor in patient falls. In a web-based survey, where responses were obtained from 102/150 (68%) therapists, 79/152 (52%) nurses and 97/132 (73%) doctors, we asked participants about their understanding of what requiring "supervision" or "stand-by assistance" when walking means. Responses to all questions differed significantly between the groups and the magnitude of the differences was greatest for the "supervision" questions. Asked if stand by assistance means the same as supervision, 71% of doctors, 35% of nurses and 14% of therapists said yes (p < 0.0001). There were also substantial within-group differences even among therapists. The widespread confusion regarding the interpretation of mobility terminology among and between different healthcare groups may impact on patient safety, and standardisation of mobility terminology is required.
