About this release

This release by Public Health Scotland reports on completed patient pathways covered by the 18 weeks Referral to Treatment (RTT) standard (90% of patients being treated within 18 weeks of referral) up to 31 March 2022. 

All Boards have encountered significant pressure on local information and intelligence resources due to the additional demands arising from the COVID-19 pandemic. As a result, data submitted since the onset of the pandemic may not have been subjected to the usual levels of quality assurance. In addition, NHS Grampian have been unable to submit data since February 2020 and NHS Tayside have been unable to submit data since May 2021. This should be taken into consideration when interpreting the statistics shown.

Main points

  • Across NHSScotland (excluding NHS Grampian and NHS Tayside), 211,589 patients were treated under this standard during the quarter ending 31 March 2022, a decrease of 2,381 (-1.1%) from the previous quarter. Within the latest quarter there were 64,460 patients treated in January, then 68,551 in February before increasing to 78,578 in March. The number treated during the latest quarter compares to a quarterly average of 272,779 in 2019 prior to the onset of the pandemic, down 22.4%.
  • The reduction in the total number of patients being seen across NHS Scotland when comparing the latest quarter to quarter-end December 2021, is not reflected at board level. Among the 13 territorial Boards that supplied data, seven have reported an increase from the previous quarter. This range of variation is captured by NHS Shetland reporting an increase of 24.1%, while the number of patients treated in NHS Ayrshire & Arran this quarter has fallen by 10.1%.
  • 84.4% of the patient journeys (excluding NHS Grampian and NHS Tayside) completed during this quarter were fully measurable against the 18-week standard. Of these, 72.8% of patients were reported as being treated within 18 weeks of referral; this is 1.6% higher than in the previous quarter but lower than the performance level just prior to the pandemic (79.5%).

The 18 Weeks RTT standard applies to the entire patient journey from the initial referral to the start of treatment. Achieving the standard depends on waiting times for diagnostic tests, new outpatient appointments, inpatient and day case treatment. 18 Weeks RTT performance is based on adjusted waits for consultant led treatments and fully measurable completed patient journeys

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.
