Background

In March 2010, the NHS Constitution was updated to include a new right for patients to start consultant-led treatment for non-urgent conditions within a maximum of 18 weeks of a GP referral. In 2012, it became a statutory requirement that at least 92% of patients should have a referral-to-treatment time of less than 18 weeks. In 2013/14, NHS England set an operational standard to ensure that no-one waits more than 52 weeks for treatment. 

A review of NHS access standards began in 2019. The interim report proposed an average wait target for people on the waiting list as a potential alternative to the current 18-week threshold target. Twelve hospital trusts began testing the use of an average (mean) wait measure in early August 2019, but publication of the review’s recommendations has been delayed. Performance of the field test sites continues to be included in the national time series, so the most recent referral-to-treatment data is unaffected by the field testing. For further information, see the Nuffield Trust blogon what the proposed changes to treatment waiting time targets could mean for hospitals and patients.

In March 2020, after the onset of the Covid-19 pandemic, non-urgent elective activity was postponed to free up inpatient and critical care capacity. In July 2020, national guidance was published outlining targets to return to near-normal levels of elective activity by autumn, but as Covid-19 cases rose over winter 2020-21, activity was disruptedagain. 

In February 2022, NHS England updated its 2022/23 priorities and operation planning guidance with the ambition to transform elective activity and reduce waiting lists. It sets targets to reduce long waits for elective treatment – namely, to eliminate waits of over 104 weeks by July 2022, waits of over 78 weeks by April 2023 and 52 week waits by March 2025.


How many people are on the waiting list for elective treatment? 29/04/2021

In mid-2007, the waiting list for elective care contained 4.2 million people, but this was reduced drastically to 2.3 million by the winter of 2009. After this, there were clear seasonal trends with the list growing over the summer and shrinking in the winter. Beyond these seasonal changes, there has been a large increase in the number of people on the waiting list for elective treatment. In February 2020, just before the Covid-19 pandemic, there were over 4.4 million people on the reported waiting list, and together with the estimate for missing data the total number of people waiting for treatment exceeded 4.5 million. 

In March 2020, the number of people on the waiting list began to fall. Although elective activity fell during the first wave of the pandemic, there was a larger drop in GP referrals, resulting in an overall reduction in the waiting list. The total waiting list reached a low of 3.9 million in May 2020 (reported waiting list plus the estimate for missing data). 

Since then, the waiting list for elective care has increased rapidly. In February 2022, there were over 6.1 million people on the waiting list, the highest number since records began. The waiting list may continue to rise while elective activity levels remain lower than before the onset of the pandemic.

The latest NHS priorities and operational planning guidance aims to reduce the elective waiting list. The guidance sets the ambition to deliver 10% more elective activity in 2022/23 than before the pandemic, and to eliminate 52-week waits by March 2025.


How has the number of people waiting over 52 weeks for elective treatment changed over time? 29/04/2022

The number of patients still waiting over 52 weeks for elective treatment after referral fell dramatically between 2007 and 2009. There was a peak in the summer of 2011 to around 20,000 patients, which corresponds to the relaxation of the central performance management of the targets in June 2010. After this, the number of people waiting over 52 weeks for treatment dropped to a low of 214 patients in November 2013. Between 2013 and 2020, there was a gradual increase in the number of patients waiting over 52 weeks, to 1,613 patients in February 2020. 

In March 2020 and March 2021, the number waiting over 52 weeks increased sharply, from 3,097 to 436,127. By February 2022, it had decreased slightly to 299,478, but this is still 186 times higher than in January 2020. The latest NHS planning guidance has set a target to eliminate 52-week waits by March 2025.


How has the proportion of patients starting treatment within 18 weeks of referral changed over time? 29/04/2022

The proportion of patients who were either admitted for treatment, still waiting for treatment or a decision had been made that they did not require elective treat within 18 weeks of a GP referral increased considerably between August 2007 and August 2008. In this time performance targets were introduced for 90% of admitted patients and 95% of non-admitted patients to start treatment within 18 weeks of referral. For patients still waiting for treatment (the waiting list), the target was set at 92%. In June 2015, the admitted and non-admitted targets were abolished and the target for patients still waiting became the sole measure of treatment waiting time performance. 

Since its introduction, performance against the 92% waiting list target has decreased. The target was first breached in December 2015, when 91.8% of patients waited less than 18 weeks, and has continued to decline. Performance fluctuated at the start of the Covid-19 pandemic, reaching a low of 47% in July 2020, then increasing to 68% in November 2020. In March 2022, only 63% of patients had been waiting less than 18 weeks to start elective treatment.

The percentage of admitted patients who waited less than 18 weeks from referral has fluctuated greatly since the Covid-19 outbreak, reaching a high of 90% in April 2020 and low of 54% in August 2020. Waiting times for admitted patients have since stabilised but continue to decline – in February 2022, 62% of patients were admitted for treatment within 18 weeks of referral.


How do treatment waiting times vary by specialty? 29/04/2022

Waiting times for elective treatment vary considerably by specialty. In February 2022, no specialty met the target that 92% of patients still waiting for treatment have been waiting less than 18 weeks. The specialties with the lowest proportion of patients waiting less than 18 weeks in February 2022 were plastic surgery (54%) ear, nose and throat (55%), and oral surgery (55%). The percentage of patients waiting less than 52 weeks to start treatment ranges from 99.8% for elderly medicine to 91.2% for plastic surgery.


How has the median treatment waiting time changed over the last ten years? 29/04/2022

The median referral-to-treatment waiting times fluctuate from month to month, but overall there has been an increase in median waits for all pathways. Between February 2011 and February 2020, median waits for patients still waiting increased by 2 weeks to 7.5 weeks, waits for admitted patients increased by 1.8 weeks to 11.2 weeks and waits for non-admitted patients increased by 2.9 weeks to 6.4 weeks.

After non-urgent elective activity was postponed during the Covid-19 pandemic, the median waiting time for patients still waiting increased sharply to a high of 20 weeks in July 2020. As activity began to resume, the median waiting time fell but remained higher than before the pandemic. In January 2022, the median waiting time for patients still waiting was 13 weeks. The median waiting time in February 2022 for admitted patients was 12.3 weeks, 4.6 weeks longer than non-admitted patients, whose median wait was 7.7 weeks.


About this data

Once there has been a decision from a consultant that a patient needs treatment and they have been referred to a hospital, they are on the waiting list and the clock starts on their referral-to-treatment waiting time. There are three different treatment pathways that are measured each month:

  • Admitted referral-to-treatment pathways are waiting times for patients whose treatment started during the month and involved admission to hospital.
  • Non-admitted referral-to-treatment pathways are waiting times for patients whose wait ended during the month for reasons other than an inpatient or day case admission to hospital for treatment.
  • Incomplete referral-to-treatment pathways are waiting times for patients still waiting to start treatment at the end of the month.

Since October 2015, no adjustments have been made to admitted referral-to-treatment pathways for clock pauses, where a patient declined reasonable offers of admission and chose to wait longer.

For further guidance on referral-to-treatment waiting times, please see the NHS England website.
