Introducing a new proforma for the safe use of intraoperative tourniquets in orthopaedic surgery

INTRODUCTION

The routine use of pneumatic tourniquets in orthopaedic surgery is widely adopted in current practice; however, practice varies considerably based mainly on anecdotal and cultural traditions. This Quality Improvement Project evaluated current service as per the newly published British Orthopaedic Association Standards for Trauma & Orthopaedics guideline on 'The Safe Use of Intraoperative Tourniquets'.

METHODS

Patient records were reviewed retrospectively for all patients who underwent orthopaedic surgery in September 2021 at one NHS hospital trust. Simultaneously, a nine-question survey was distributed to the orthopaedic teams allowing assessment of non-quantifiable aspects of the guidelines. The results were delivered as a local presentation, and trust-wide dissemination of posters using the mnemonic 'PRESSURE' was used to educate staff. The quantitative audit was repeated twice, after this intervention (March 2022) and after the advent of a new electronic patient record system with an online proforma (January 2023).

RESULTS

There was significant improvement (p<0.05) in all aspects of tourniquet documentation between the audit cycles. Maximum advised tourniquet duration was exceeded in <2% of cases regardless of guideline publication. Recommended pressures were used in less than one-third of cases in all audit cycles, with no significant change throughout. More than 50% of respondents sized their tourniquet on 'whatever looked best fit'.

CONCLUSIONS

Despite tourniquet usage being part of the UK Trauma & Orthopaedic Surgery curriculum, this study is the first to highlight a lack of compliance with 'gold standard' guidelines and the need for increased training for staff to ensure patients are exposed to the safest possible environment. Although electronic proformas can aid recording of information, the limitation to change is cultural tradition and anecdotal experience.
