Cet essai contrôlé randomisé multicentrique a évalué l’efficacité des chaussures antidérapantes classées 5* GRIP pour prévenir les glissades sur le lieu de travail, par rapport aux chaussures habituelles (groupe témoin). L’étude, menée sur 14 semaines et impliquant 4553 employés du Service national de santé (NHS), a montré une réduction statistiquement significative du taux de glissement dans le groupe d’intervention par rapport au groupe de contrôle.
Objectives Assess the effectiveness of 5* GRIP-rated slip-resistant footwear in preventing slips in the workplace compared to usual footwear (control group). Methods A multicentre, randomised controlled trial; 4553 National Health Service (NHS) staff were randomised 1:1 to the intervention group (provided with 5* GRIP-rated slip-resistant footwear) or the control group. The primary outcome of incidence rate of self-reported slips in the workplace over 14 weeks was analysed using a mixed-effects negative binomial model. Secondary outcome measures included incidence rate of falls from a slip, falls not from a slip, proportion of participants reporting a slip, fall or fracture and time to first slip and fall. Results 6743 slips were reported: 2633 in the intervention group (mean 1.16 per participant, range 0 to 36) and 4110 in the control group (mean 1.80 per participant, range 0 to 83). There was a statistically significant reduction in slip rate in the intervention group relative to the control group (incidence rate ratio (IRR) 0.63, 95% CI 0.57 to 0.70, p<0.001). Statistically significant differences, in favour of the intervention group, were observed in falls from a slip (IRR 0.51, 95% CI 0.28 to 0.92, p=0.03), the proportion of participants who reported a slip (OR 0.58, 95% CI 0.50 to 0.66, p<0.001) or fall (OR 0.73, 95% CI 0.54 to 0.99, p=0.04) and time to first slip (HR 0.73, 95% CI 0.67 to 0.80, p<0.001). Conclusions The offer and provision of 5* GRIP-rated footwear reduced slips in NHS staff in the workplace. Trial registration number ISRCTN33051393. Lisez l’article
