Variation in surgery postponement rates in the NHS in England.

Introduction: Postponement of surgery at preoperative assessment in the days or weeks before the patient is admitted for surgery, as distinct from cancellation on the planned day of surgery, can be devastating for patients and an inefficient use of finite resources. However, postponements are often poorly recorded. The primary aim of this pilot study was to investigate elective surgical postponement rates during or after preoperative assessment across England, and the reasons for postponement for patients on an elective surgical pathway.

Methods: A retrospective analysis of clinical audit data from 16 National Health Service (NHS) trusts in England was undertaken. Data were collected during a two-week period in March 2024 on all postponements within a service. The primary outcome of interest was the postponement rate.

Results: Some 8000 case notes were reviewed. There were 583 (7.3%) postponements. Postponement rates across trusts varied from 31.9% to 1.0%. Significantly shorter time from referral to preoperative assessment was observed for day-case patients, urgent patients, patients without early screening and patients without a 'to come in' date in place. Of the 342 routine patients, 293 (85.7%) had postponements for medical rather than pathways or process reasons. Half of all routine patients waited over 94 days and a quarter of patients waited 198 days from being added to a patient tracking list to preoperative assessment.

Conclusions: Minimizing postponements and improving preoperative assessment efficiency should be part of wider initiatives to streamline perioperative pathways.
