About this release
This quarterly release by Public Health Scotland relates to the number of patients waiting for one of eight key diagnostics tests and investigations and the time they have waited. The eight key tests and investigation are upper endoscopy, lower endoscopy (excl. colonoscopy), colonoscopy, cystoscopy, CT scan, MRI scan, barium studies and non-obstetric ultrasound.
At 31 December 2021:
- 141,262 patients were waiting to be seen for the eight key diagnostic tests, an increase of 12.5% (+15,705) from 30 September 2021 and 40% higher than at 31 December 2020. When comparing to pre-pandemic levels, the waiting list size is 59.8% higher than the 12-month average prior to the onset of the pandemic (Mar 19 – Feb 20).
- Of those waiting for one of the eight key tests, 49.6% had been waiting six weeks or less (42 days), compared to 57.8% at 30 September 2021 and 55.9% at 31 December 2020. However, there is a notable difference across test types and Health Boards, ranging from 23.3% to 97.4% for an endoscopy and 34.9% to 100% for a radiology test.
- 34,224 patients were waiting for an endoscopy, a decrease of 1.5% from 30 September 2021, but an increase of 8.2% from 31 December 2020 and 53.1% when compared to the 12-month average prior to the onset of the pandemic. Of those waiting, 33.4% had been waiting six weeks or less; lower than both the pre-pandemic average of 66.6% and 33.9% at 30 September 2021 but higher than 32.2% at 31 December 2020.
- The percentage of patients who had been waiting over 52 weeks for an endoscopy increased slightly from 11.2% at 30 September 2021, to 13.0% (4,436 patients, +553) at 30 December 2021, which is markedly higher when compared to the 3.9% (1,236) reported at the same date the previous year.
- 106,912 patients were waiting for a radiology test, an increase of 17.7% from 30 September 2021, 54.3% from 31 December 2020 and 61.8% when compared to the 12-month average prior to the onset of the pandemic. Of those waiting, 54.7% had been waiting six weeks or less; lower than the pre-pandemic average of 86.6%, 66.9% at 30 September 2021 and 66.7% at 31 December 2020.
- The percentage of patients who had been waiting over 13 weeks for a radiology test has increased from 8.8% at 30 September 2021 to 15.8% (16,943 patients, +8,976) at 31 December 2021. This compares to 11.8% (8,181) waiting over 13 weeks at the same date the previous year. On average, only 1.8% of patients were waiting over 13 weeks in the 12 months prior to the pandemic.
The services involved continue to be affected by COVID-19 (Coronavirus) pandemic. In the early stages of the outbreak most non-urgent treatment was paused or reduced and there were fewer referrals to services. Since then services have been remobilising (external website) but capacity is constrained by the requirement for additional infection control measures. In addition, further waves of the virus have slowed the recovery of services due to the need to again pause or reduce services for reasons such as increased staff absence or the need to divert resources because of an increase in unscheduled hospitalisations.
