Introduction
This statistical release provides a monthly summary of NHS Wales activity and performance data. Longer term trends are explored in our annual reports, Trends in NHS urgent and emergency care activity and Trends in NHS planned care activity
In light of the impact COVID-19 has had on NHS activity and performance levels, the Welsh Government has published its programme for transforming and modernising planned care and reducing waiting lists in Wales. This plan sets out a number of key ambitions to reduce waiting times for people in Wales. We have incorporated performance measures against these ambitions into this statistical release and on StatsWales.
Data provided in this statistical report has been provided by Digital Health and Care Wales (DHCW) unless stated otherwise. Data for each topic area are also available in more detail on our StatsWales website.
Main points
In April there were 5,172 red (life threatening) calls to the ambulance service, 15.5% of all calls, 0.6 percentage points lower than in March. An average of 172 immediately life-threatening calls were made each day.
50.9% of red calls received an emergency response within eight minutes. This was 0.6 percentage points higher than in March. Data for red calls are only comparable from May 2019 onwards.
There was an average of 3,124 daily attendances to emergency departments, an increase compared to the previous month. Performance against the four hour target and performance against the twelve hour target both improved compared with the previous month. The average time spent in emergency departments in April was 3 minutes shorter than the previous month at 2 hours and 45 minutes.
The pandemic has caused a large increase in patient pathways waiting to start treatment. In March the number decreased from just over 793,900 to just over 790,000. The number of patient pathways is not the same as the number of individual patients, because some people have multiple open pathways. More information is available in the Welsh Government’s chief statistician’s blog.
Management information suggests that in March, when there were just over 790,000 open patient pathways, there were about 608,600 individual patients on treatment waiting lists in Wales.
The proportion of patient pathways waiting less than 26 weeks increased to 55.2% in March. This has been relatively stable after falling significantly from the levels pre-pandemic. The number of pathways waiting longer than 36 weeks decreased in March, to just over 268,400.
Just under 8,400 pathways were waiting more than two years, the lowest figure since April 2021, more than three quarters (88.1%) lower than the peak, and a 45.9% decrease from the previous month. The average time patient pathways had been waiting for treatment at the end of March was 0.5 weeks lower than the previous month at 22.1 weeks.
The planned care recovery plan established a target to eliminate two year waits in most specialties by March 2023, with ‘most’ referring to all specialties excluding seven recognised as exceptionally challenging even prior to the pandemic. The target was not met in March 2023 and in March there were still a further 9 specialties with pathways waiting more than two years accounting for 1,558 pathways, a decrease of 550 compared to last month.
Headline measures for open pathways across the UK are not comparable. There are large differences between Wales, Scotland and Northern Ireland statistics, meaning they should not be compared at all. With England, current understanding suggests a broadly comparable number can be produced for Wales by removing some known non-consultant led pathways which are not counted in England. On that basis, there are around 710,600 open pathways on consultant-led pathways in Wales, equivalent to 23 pathways (not patients) for every 100 people. For England, the figure in March was 13 pathways for every 100 people.
Pathways waiting longer than one year for their first outpatient appointment decreased from the previous month to just under 71,000, 30.9% less than the peak in August 2022.
For diagnostic services, patient pathways waiting increased to just under 112,900 in March. The number waiting longer than eight weeks (the target maximum wait) decreased to just over 35,200, the lowest figure since March 2020. For therapies, patient pathways waiting increased to just over 57,400 therapies waiting in March. The number waiting longer than fourteen weeks (the target maximum wait) decreased to just over 4,000.
For cancer services, 1,880 people started their first definitive treatment in March, 50 more than the previous month. The number of pathways closed following the patient being informed they did not have cancer increased to 14,762. Performance improved against the 62 day target in March, increasing to 63.5%, the highest figure since the current data collection began in March 2022.
Statement on comparability
The provision of health services is devolved across the four nations of the UK. As a result, the way we measure NHS activity and performance in each nation differs. A joint statement on the coherence of these statistics, and advice on how and when to make comparisons across the UK has been published on the Analysis Function website.
Unscheduled care
New data relating to unscheduled care are provided for the month of April 2025.
Calls to 111 service

111 service activity in Wales, by date and measure, on StatsWales
In April, a total of 82,657 calls were made to the 111 helpline service, an increase of around 1,700 calls compared to the previous month. Of these, just under 67,000 (81.1%) calls were answered, an average of 2,233 calls per day.
An estimated 15,661 (18.9%) calls were ended by the caller before being answered. Of these, 5,714 were ended within 60 seconds of the automated messages, suggesting their needs were likely to have been met.
9,947 calls were abandoned after 60 seconds and these are regarded as callers who were more likely to have still required the service after the messages but were unable to get through or decided not to wait.
Of the calls answered, 1,727 calls indicated that they wished to conduct the call in Welsh.
There were just under 420,200 hits on the NHS 111 Wales website, and just over 11,500 completed symptom checks (NHS 111 Wales) in April.
Emergency calls to the ambulance service
A wider range of ambulance quality indicators are published on StatsWales and on the NHS Wales Joint Commissioning Committee website.
Calls to the ambulance service are categorised as red (immediately life-threatening), amber (serious but not life-threatening) or green (non-urgent).

Emergency ambulance calls and responses to red calls, by local health board and month, on StatsWales
[Note 1] An update to call handling in May 2019 resulted in a change to red incident volume. It is not possible to directly compare before and after this date. Further details are available in the quality information.
In April, just over 33,400 emergency calls were made to the ambulance service. This was an average of 1,115 calls per day, on average 32 more calls per day than the previous month, and 20 (1.8%) more per day than the same month last year.
An average of 172 red calls were made per day in April, 2 fewer than the previous month.
In April, the proportion of all calls that were immediately life-threatening was 15.5%, 0.6 percentage points lower than March. The number of green calls has steadily decreased over time, while the number of red calls has steadily increased.
Performance
Target
- 65% of red calls (immediately life-threatening, someone is in imminent danger of death, such as a cardiac arrest) to have a response within 8 minutes.

[Note 1]: An update to call handling in May 2019 resulted in a change to red incident volume. It is not possible to directly compare before and after this date. Further details are available in the quality information.
In April, 50.9% of emergency responses to immediately life threatening (red) calls arrived within 8 minutes of patient location and chief complaint being established. This was 0.6 percentage points higher than in the previous month.
The proportion of red calls responded to within 8 minutes has fallen in recent years from a peak of 80% in 2017, but over the same period there has been a significant increase in the number of red calls received. For example, in the latest twelve months there were around 65,000 red calls, close to three times as many as in 2017 (22,000). The overall increase in demand largely reflects two things; changes in how some calls are handled, as some calls that used to be categorised as amber are now categorised as red; and a large increase in respiratory conditions in recent winters.
Other than demand, handover delays at hospitals can also affect performance, when ambulance crews are unable to respond to new calls while waiting to handover patients to emergency departments. There has been a significant increase in handover delays in recent years, with more than four times as many hours lost in the latest twelve months compared with 2017. In April around 21,000 hours were lost due to handover delays. Further data on handover delays can be found on the Emergency Ambulance Services Committee’s (EASC) Ambulance Service Indicators dashboard.
The median response time in the four years prior to the pandemic ranged between 4 minutes 30 seconds and 6 minutes for red calls. In April, the average (median) response time to immediately life-threatening ‘red’ calls was 7 minutes 52 seconds. This was 6 seconds faster than the previous month, and 25 seconds quicker than April 2024.
The majority of calls to the ambulance service are categorised as ‘amber’ calls, for which there is no performance target for call response times. In April, the median response time for amber calls was just over 1 hour 54 minutes. This was just under 2 minutes faster than in March, but just over 39 minutes slower than in April 2024.
Emergency department attendances and admissions to hospital
A wider range of emergency department performance statistics are published on the National Collaborative Commissioning Unit (NCCU) website, as management information.

[Note 1]: Chart shows number of attendances at both major emergency departments and minor injuries units, and the number of admissions resulting from attending major emergency departments only.
In April there were just over 93,700 attendances to all emergency departments, an average of 3,124 attendances per day; this was 17 attendances more per day on average than in the previous month and 87 more than April 2024.
In April, just under 14,700 patients were admitted to the same or a different hospital following attendance at major emergency departments. This was 0.2% lower than the previous month, but 0.2% higher than the same month in 2024.
Performance
Targets
- 95% of new patients should spend less than 4 hours in emergency departments from arrival until admission, transfer or discharge.
- No patient waiting more than 12 hours in emergency departments from arrival until admission, transfer or discharge.

Performance against 4 hour target by hospital, on StatsWales
In April, 67.7% of patients in all NHS emergency departments spent less than 4 hours in the department from arrival until admission, transfer or discharge. This was higher than the previous month, but remains relatively low in historical context.
In 2019, the median time patients spent in emergency departments was around 2 hours and 30 minutes. During the early part of the pandemic, as attendances decreased the median time spent in the department decreased, to a low of 1 hours 47 minutes in April 2020. Since then, median times increased and reached a record high of 3 hours and 8 minutes in March 2022. In the latest data for April, the median waiting time was 2 hours and 45 minutes, down 3 minutes from the previous month.
The median time spent in emergency department varies by age. Prior to the pandemic, children (aged 0 to 4) spent between 1 hour and 30 minutes and 2 hours in emergency departments, while older patients (aged 85 or greater) spent between 3 hours and 30 minutes and 5 hours.
In April, children (aged 0 to 4) spent an average of 2 hours and 6 minutes in emergency departments. Adults aged 85 and over spent an average of 5 hours and 59 minutes in emergency departments.

Performance against the 12 hour target by hospital, on StatsWales
In April, 10,186 patients waited 12 hours or more. This was 195 (1.9%) fewer than in the previous month.
Scheduled care activity
New data relating to scheduled care are provided for the month of March 2025. Digital Health and Care Wales (DHCW) now publishes a secondary care dashboard which provides data on outpatients appointments, inpatient admissions and daycase activity undertaken in Wales.
Outpatient referrals and appointments

Referrals by local health board and month, on StatsWales
An average of 4,316 referrals for first outpatient appointments were made per day in March 2025. This is a decrease of 4.8% (220 fewer referrals per day on average) compared to February 2025, but an increase of 9.7% compared to March 2024.
Performance
Targets
- No one waiting for longer than a year for their first outpatient appointment by the end of 2022 (a target established in the planned care recovery plan).

Diagnostic and Therapy Services Waiting Times by week, on StatsWales
[Note 1]: The low point in April 2020 for therapies is in part due to Betsi Cadwaladr not submitting data for this month, please see the quality information for more information.
[Note 2]: The April 2024 figures for therapies pathways were affected by changes to the way the data are collected. Specifically, audiology (which is now reported separately on StatsWales) and weight management pathways are no longer reported in the therapies data. Further detail on this was provided in June’s release.
In March there were just under 112,900 patient pathways waiting for diagnostics. This was an increase of 0.4% compared with the previous month.
In March there were just over 57,400 patient pathways waiting for therapies. This was an increase of 6.5% compared with the previous month.
Performance
Targets
- The maximum wait for access to specified diagnostic tests is 8 weeks.
- The maximum wait for access to specified therapy services is 14 weeks.
- The planned care recovery plan established a target date of Spring 2024 to reach these targets.

Diagnostic and Therapy Services Waiting Times by week, on StatsWales
[Note 1]: From April 2024 audiology and weight management pathways were no longer reported in the therapies data, meaning they are not directly comparable with data up to March 2024.
At the end of March, just over 35,200 patient pathways were waiting longer than the target time for diagnostics. This was a decrease of 5.7% compared to the previous month and the lowest figure since March 2020. The planned care recovery target, to eliminate waits of more than 8 weeks for diagnostics tests by Spring (March) 2024, was not met.
At the end of March there were just over 4,000 patient pathways waiting longer than the target time for therapies. This was a decrease of 3.3% compared to the previous month and the lowest figure since August 2021. The planned care recovery target, to eliminate waits of more than 14 weeks by Spring (March) 2024, was not met.
Median waiting times had been relatively stable for diagnostic tests since 2017 (2.8 weeks on average) and for therapy services since 2018 (3.6 weeks on average). Median waiting times for both services peaked in 2020 (14.3 weeks for diagnostics and 14.9 weeks for therapies).
In March, the median waiting time for diagnostic tests was 4.5 weeks, the same as the previous month. The median waiting time for therapy services was 4.1 weeks, compared with 3.9 the previous month.
Referral to treatment time
Referral to treatment time statistics show monthly data on waiting times for both open and closed pathways following a referral by a GP or other medical practitioner to hospital for treatment in the NHS. Open pathways are those that remain on the waiting list for treatment, whereas closed pathways are those taken off the waiting list.
Activity is measured by patient pathways, which differs to the number of patients. More information on this difference is available in the Welsh Government’s Chief Statisticians blog.
Also published is management information for the number of individual patients on treatment waiting lists in Wales.
Performance
Targets
- No patients waiting longer than two years in most specialities by March 2023, and no patients waiting longer than one year in most specialities by Spring 2025 (new targets established in the planned care recovery plan).
- 95% of patients waiting less than 26 weeks from referral.
- No patients waiting more than 36 weeks for treatment from referral.

In March there were just over 790,000 patient pathways waiting to start treatment. This was a decrease of around 3,900 pathways from February, but 74.0% higher than May 2020.
Headline measures for open pathways across the UK are not comparable. There are large differences in coverage between Wales, Scotland and Northern Ireland statistics, meaning they should not be compared at all. With England, current understanding suggests a broadly comparable number can be produced for Wales by removing some known non-consultant led pathways which are not counted in England. On that basis, there are around 710,600 open pathways on consultant-led pathways in Wales, equivalent to 23 pathways (not patients) for every 100 people. For England, the figure in March was 13 pathways for every 100 people. These comparisons are explored further in this Chief Statistician’s blog.
Of the total 790,000 pathways, just over 155,800 were waiting more than one year in March. This number was 3.5% lower than last month and 15.1% lower than the peak in August 2022. Just under 8,400 were waiting more than two years. This number is 45.9% lower than last month, the lowest figure since April 2021, and more than three quarters (88.1%) lower than the peak in March 2022.
The planned care recovery plan established a target to eliminate two year waits in most specialties by March 2023 and one year waits in most specialties by March 2025. This is assessed on the basis that ‘most’ refers to all specialties excluding seven recognised as exceptionally challenging, with large numbers waiting even prior to the COVID-19 pandemic. These are Dermatology, General Surgery, Ophthalmology, Urology, Gynaecology, Orthopaedics and Ear, Nose and Throat. The target for two year waits was not met in March 2023, and in March there were still a further 9 specialties with pathways waiting more than two years accounting for 1,558 pathways, a decrease of 550 compared to last month. The target for one year waits was not met in March 2025 and there were still a further 33 specialties with pathways waiting more than one year accounting for 28,346 pathways.
The number of patient pathways is not the same as the number of individual patients, because some people have multiple open pathways.
We do not have official statistics on the number of individual patients waiting to start treatment. However, management information suggests that in March, when the National Statistics (above) reported there were just over 790,000 open patient pathways, there were estimated to be about 608,600 individual patients on treatment waiting lists in Wales. Estimates for the number of individual patients waiting to start treatment by health board can be found on StatsWales: Unique Patient Estimates.
Unlike the National Statistics elsewhere in this release, which have been independently assessed against the Code of Practice for statistics, this estimate is based on management information. Whilst the principles of the Code of Practice have been applied, quality assurance is not to the level of the National Statistics. Work is ongoing to further understand the strengths and limitations of this data and this will be communicated as we learn more. For these reasons there is greater uncertainty around this estimate than with the other figures in this release. However, the level of public interest in understanding the number of patients in addition to the number of patient pathways adds sufficient value to warrant making this available.

In March, just over 268,400 patient pathways had been waiting more than 36 weeks. This represented 34.0% of all patient pathways waiting to start treatment. This was 7,560 (2.7%) lower than in the previous month.
The median time waiting to start treatment had generally been around 10 weeks pre pandemic between late 2013 and February 2020. This increased during the pandemic and peaked at a record high of 29 weeks in October 2020. In March, the median waiting time was 22.1 weeks, 0.5 weeks lower than the previous month.

[Note 1]: Data revised to now include Cwm Taf Morgannwg health board closed pathways. Up to the July 2022 statistical release, the data series was not available for Cwm Tag Morgannwg. More details are available in the quality information.
The number of patient pathways closed in March was just over 124,300, the highest monthly figure on record. This was an average of 5,920 patient pathways closed per working day. This was an increase of 178 patient pathways (or 3.1%) closed per working day from the previous month and 764 more than the same month last year.

Suspected cancer pathway (closed pathways), on StatsWales
[Note 1]: New suspected cancer pathway data collection was introduced in December 2020.
In March, 1,880 pathways where the patient was newly diagnosed with cancer started their first definitive treatment in the month. This was 50 more than the previous month.
14,762 pathways were closed following the patient being informed they did not have cancer. This is an increase of 13.4% compared to the previous month.
In March, 17,129 patient pathways were opened in the month following a new suspicion of cancer. This was an increase of 1,045 (6.5%) on the previous month, and an increase of 10.3% compared to March 2024. In recent years the number of new pathways opened has fluctuated, but has stabilised in recent months.
Performance
Target
- At least 75% of patients should start treatment within 62 days (without suspensions) of first being suspected of cancer. Data published for time periods before December 2020 are not subject to the target.
- The planned care recovery plan established a new target of 80%, to be reached by 2026.

[Note 1]: New suspected cancer pathway data collection was introduced in December 2020, with a performance target of 75%. The planned care recovery plan established a new target of 80%, to be reached by 2026.
In March, 63.5% of pathways started their first definitive treatment within 62 days of first being suspected of cancer. This was 3.3 percentage points higher than the previous month, and the highest figure since the current data collection started in March 2022.
Focus on local health boards
Local health board performance is covered in the quarterly release NHS performance for Welsh local health boards. For the months this is not produced, summary analyses will be provided in this section.
Of the measures covered in this report; Swansea Bay and Powys are currently meeting the therapy services target (no pathways waiting longer than 14 weeks), have no pathways waiting longer than two years and no one-year waits for a first outpatient appointment; Hywel Dda also has no two-year waits and no one-year waits for first outpatient appointments. All other health boards are not currently meeting any of the performance targets. For some measures, Powys is not directly comparable with the other health boards (because of differences in the services provided), and is therefore not included in the charts below.
For emergency ambulance or ‘red’ calls, in April Aneurin Bevan had the highest proportion of responses within 8 minutes at 53.8%. Powys had the lowest at 40.6%.
In emergency departments, Aneurin Bevan had the highest proportion of patients admitted, transferred or discharged within the 4 hour target at 78.3%, while Betsi Cadwaladr had the lowest at 60.8%.
Aneurin Bevan had the lowest percentage waiting longer than 12 hours in emergency departments at 7.0%, while Betsi Cadwaladr has the highest at 16.9%.
Betsi Cadwaladr had the highest proportion of RTT pathways waiting longer than one year in March, at 26.3% of pathways, whereas Hywel Dda had the lowest, at 13.1% of pathways. Betsi Cadwaladr also had the highest proportion waiting longer than two years at 2.9%, and Swansea Bay and Hywel Dda both had the lowest with no pathways waiting longer than two years.
For first outpatient appointments, the highest proportion waiting longer than one year in March was currently in Betsi Cadwaladr at 26.7% of pathways and the lowest was in both Swansea Bay and Hywel Dda where there were no pathways waiting longer than one year.
Cardiff and Vale currently has the highest proportion of diagnostic waits longer than the target time of 8 weeks at 55.1% of pathways and Aneurin Bevan has the lowest at 7.2%.
For therapies, Hywel Dda currently has the highest proportion waiting longer than the target of 14 weeks at 20.8% of pathways, and Powys and Swansea Bay have the lowest with no pathways waiting over 14 weeks.

Quality and methodology information
All quality and methodology information in relation to this statistical release can be found in the NHS activity and performance summary: quality report
Official statistics status
All official statistics should show the standards of the Code of Practice for Statistics (UK Statistics Authority).
These are accredited official statistics. They were independently reviewed by the Office for Statistics Regulation in July 2012. They comply with the standards of trustworthiness, quality, and value in the Code of Practice for Statistics.
It is Welsh Government’s responsibility to maintain compliance with the standards expected of accreditation. If we become concerned about whether these statistics are still meeting the appropriate standards, we will discuss any concerns with OSR promptly. Accreditation can be cancelled or suspended at any point when the highest standards are not maintained, and reinstated when standards are restored.
Accredited official statistics (Office for Statistics Regulation) (OSR) are called National Statistics in the Statistics and Registration Service Act 2007.
Statement of compliance with the Code of Practice for Statistics
Our statistical practice is regulated by the Office for Statistics Regulation (OSR). OSR sets the standards of trustworthiness, quality and value in the Code of Practice for Statistics that all producers of official statistics should adhere to.
All of our statistics are produced and published in accordance with a number of statements and protocols to enhance trustworthiness, quality and value. These are set out in the Welsh Government’s Statement of Compliance.
These accredited official statistics demonstrate the standards expected around trustworthiness, quality and public value in the following ways.
Trustworthiness
These statistics are compiled from a range of sources derived from administrative data systems in use across the NHS in Wales. Data on the 111 service, 999 ambulance calls and ambulance response times are provided by the Wales Ambulance Services NHS Trust (WAST), and all other data sources are collected by the Welsh Local Health Boards and provided to Digital Health and Care Wales (DHCW) to enable them to be collated at a national level.
The data collections are overseen by the Welsh Information Standards Board (WISB), which is the custodian of the Information Standards Assurance Process. WISB mandates data collections through the NHS and Local Heath Boards, appraises information standards and provides assurance on matters related to confidentiality and consent.
The published figures are compiled by professional analysts using the latest available data and applying methods using their professional judgement and analytical skillset.
These statistics are pre-announced on the Statistics and Research area of the Welsh Government website. Access to the data during processing is restricted to those involved in the production of the statistics, quality assurance and for operational purposes. Pre-release access is restricted to eligible recipients in line with the Code of Practice.
Quality
Statistics published by Welsh Government adhere to the Statistical Quality Management Strategy which supplements the Quality pillar of the Code of Practice for Statistics and the European Statistical System principles of quality for statistical outputs.
Data standards and definitions are established by the Welsh Information Standards Board (WISB). Guidance is issued to the data providing organisations and training provided to staff responsible for collecting the data at source. DHCW collates and validates health board level data and queries anomalous and missing data directly with the health boards. Before validated datasets are provided by DHCW to Welsh Government, all data are signed off by health boards. DHCW provides validated datasets to Welsh Government, where analysts process the data to produce the aggregate statistics in the format required for publication. Welsh Government undertakes final validation checks which can be queried with DHCW and the health boards before publication. The statistical release is signed off by senior statisticians before publication.
Value
The purposes of this statistical release and the accompanying data published on StatsWales are: to provide evidence for policy development; to inform the media and wider public about activity and performance in the Welsh NHS; to enable service providers such as Local Health Boards and WAST to monitor their own performance.
Reliable statistics on the volume of activity undertaken in the NHS, the size of waiting lists, ambulance response times and emergency department and cancer waiting times are vital to inform users about the state of NHS services and the performance of the Welsh government and the Local Health Boards. These services have a significant impact on citizens’ lives and these topics feature prominently in media coverage and political discourse.
The information published here also supports the Welsh Government’s long term plan for health and social care: A Healthier Wales.
The timeliness of the data provides the most recent update using reliable data.
You are welcome to contact us directly with any comments about how we meet these standards. Alternatively, you can contact OSR by emailing regulation@statistics.gov.uk or via the OSR website.
Well-being of Future Generations Act (WFG)
The Well-being of Future Generations Act 2015 is about improving the social, economic, environmental and cultural wellbeing of Wales. The Act puts in place seven wellbeing goals for Wales. These are for a more equal, prosperous, resilient, healthier and globally responsible Wales, with cohesive communities and a vibrant culture and thriving Welsh language. Under section (10)(1) of the Act, the Welsh Ministers must (a) publish indicators (“national indicators”) that must be applied for the purpose of measuring progress towards the achievement of the wellbeing goals, and (b) lay a copy of the national indicators before Senedd Cymru. Under section 10(8) of the Well-being of Future Generations Act, where the Welsh Ministers revise the national indicators, they must as soon as reasonably practicable (a) publish the indicators as revised and (b) lay a copy of them before the Senedd. These national indicators were laid before the Senedd in 2021. The indicators laid on 14 December 2021 replace the set laid on 16 March 2016.
Information on the indicators, along with narratives for each of the wellbeing goals and associated technical information is available in the Wellbeing of Wales report.
Further information on the Well-being of Future Generations (Wales) Act 2015.
The statistics included in this release could also provide supporting narrative to the national indicators and be used by public services boards in relation to their local wellbeing assessments and local wellbeing plans.
