This is a line chart showing data on the total percentage of patients in NHS Scotland who had their Planned Operation Cancelled for the reasons of clinical, non-clinical/capacity, cancelled by patient and other reason. Data is from February 2020 to February 2021. A red vertical line at March 2020 shows the point where the NHS was placed under emergency measures to the COVID-19 pandemic. The data shows a peak in non-clinical/capacity reasons in March 2020 due to the emergency measures.


These statistics are released monthly. Data for this publication are submitted from NHS Board theatre systems.

The following definitions are used for the cancellation reason groupings:

  • Cancellation based on clinical reason by hospital includes 'patient unwell', 'patient not prepared for procedure correctly by hospital' and 'patient did not follow pre op instruction'.
  • Cancellation based on capacity or non-clinical reason by hospital includes 'no beds available', 'staff not available', 'equipment not available' and 'theatre session overran'.
  • Cancellation by patient includes 'patient decides not to go ahead with procedure', 'patient unable to attend', 'patient did not attend' and 'patient did not attend pre-op'.
  • Other includes 'fire alarm prevents operation from taking place', 'weather prevented patient / staff travelling' and 'patient transport did not arrive in time to bring patient to hospital'.

These statistics continue to be affected by the COVID-19 (Coronavirus) pandemic. During the early stage of the outbreak many operations were cancelled well ahead of their planned date, particularly if related to non-urgent elective treatment. From the 19 June, Boards started to resume some services as part of the planned remobilisation of services (external website), which will include the rescheduling of cancelled procedures. Then, as a second wave of COVID-19 cases emerged through the autumn months, a strategic national framework (external website) was introduced by the Scottish Government with the aim of supressing the virus to the lowest possible level whilst tackling the 'harms' caused by the pandemic. This included maximising the safe and effective resumption of planned services where possible, whilst balancing the need to ensure sufficient capacity to respond to the resurgence of COVID-19. On the 18 November the SG published a Clinical Prioritisation Framework (external website) with the aim of providing guidance on how patients waiting for treatment should be prioritised whilst ensuring appropriate COVID-19 safety and priority measures are in place.
