About this release

This release by Public Health Scotland (PHS) provides a monthly update on the number of operations in NHSScotland that were cancelled the day before, or on the day the patient was due to be treated. Information on the reasons for cancellations are also included.

It should be highlighted that these statistics are affected by the COVID-19 (Coronavirus) outbreak. In particular, on the 17 March, NHSScotland was placed under emergency measures and Boards were asked to suspend all non-urgent elective treatment. Later, on the 23 March, the nation entered a period of ‘lockdown’. This means many operations planned for April were cancelled long before they were due to take place.

Main points

  • The total number of planned operations across NHSScotland during April 2020 was 3,406, a decrease of 83.1% from 20,192 in March 2020 and 87.5% from 27,204 during April 2019.
  • In April 2020, 458 operations, or 13.4% of all planned operations, were cancelled the day before or on the day the patient was due to be treated. This compares to 2,310 (8.5%) in April 2019. At Health Board level this percentage ranged from 0% to 25%.
  • In April 2020, of all planned operations cancelled in this way:
    • 3.3% were cancelled by the patient
    • 5.0% were cancelled by the hospital based on clinical reasons
    • 4.1% were cancelled by the hospital due to capacity or non-clinical reasons
    • 1.0% were cancelled due to other reasons.
