Background:
Reusable surgical drapes have a lower lifetime environmental impact than disposable drapes in most cases. There is limited evidence regarding whether drape choice impacts patient outcomes including post-operative wound complications. The aim of this study is to compare wound complication rates following routine neutering surgeries in cats and dogs when reusable drapes are used as compared with disposable drapes.
Methods:
The trial will be conducted as a pragmatic, multi-centre, parallel group randomised controlled trial in the UK. Dogs and cats undergoing routine neutering will be randomised to disposable or reusable drapes with all other aspects of care occurring as they usually would at the practice. The required sample size is 2,850, with 4750 animals to be recruited from up to ten practices to allow for a 40% loss to follow-up. Demographic data and details on peri-operative care will be collected at the time of surgery. Post-operative wound complications will be assessed and recorded as usual at each practice using clinical codes. The post-operative wound clinical codes and any antibiotic use within 30 days of surgery will be retrieved from the practice management software. The primary outcome that will be compared between the two groups is the rate of post-operative wound complications within 30 days of surgery which will be analysed by multivariable logistic regression with a binary outcome of wound complication (yes/no). Secondary outcomes are the prevalence of different types of complications and antibiotic use within 30 days of surgery which will be compared between the two groups by chi square analysis.
Discussion:
Our hypothesis is that there will be no difference in post-operative wound complication rates between disposable and reusable drapes. If the likely rate of post-surgical wound complications with reusable drapes is similar to that with disposable drapes, then veterinary clinical teams can choose the more sustainable option, confident that their patients will not be impacted by this choice.
Trial Registration:
We have retrospectively registered the protocol on the Open Science Framework on 14 Nov 2023 (Trial registration entry: https://doi.org/10.17605/OSF.IO/72HMA ).
