A cost analysis of local anaesthetic nose and sinus surgery for the treatment of chronic rhinosinusitis

Abstract

Background: People with chronic rhinosinusitis may be referred for endoscopic sinus surgery (ESS), a procedure commonly performed under general anaesthesia, once maximal medical therapy has failed. A new pathway of care is emerging: Local Anaesthetic Nose & Sinus Surgery (LANSS). With LANSS the patient is not placed under general anaesthesia, but instead the procedure is performed under a local anaesthetic. Methodology: A decision analytic model was developed from the perspective of the UK National Health Service (NHS) to assess the potential cost impact of LANSS versus current standard care pathway for ESS. Results: Modelling indicated that the introduction of LANSS would generate substantial savings of around £84,500 per year if introduced to a typical NHS trust with a large otolaryngology department undertaking 300 ESS procedures per year. These savings are generated as a proportion of the ESS procedures no longer need to be completed in an operating theatre, which reduces operational costs (saving around £64,500 per year), plus the use of local anaesthetic instead of general anaesthetic and a reduction in the time a patient spends as an inpatient. Conclusions: The uptake of LANSS could generate cost-savings of around £84,500 per year to a typical NHS trust in the UK.
