Coverage: Northern Ireland
Frequency: Quarterly
On 9 November 2023 the South Eastern Health and Social Care (HSC) Trust launched ‘encompass’ - a new electronic patient record system. The system also went live in Belfast Trust on 6 June 2024, in Northern Trust on 7 November 2024, and in Southern and Western Trusts on 8 May 2025. Consequently, as the Belfast, Northern and South Eastern Trusts transition to completely digitised health records, their data have been presented separately.
The data which it has been possible to include for Belfast, Northern and South Eastern HSC Trusts (disaggregated data for Belfast for Quarter Ending June 2024, and data for Northern for Quarter Ending December 2024, are not currently available), have been presented in a separate ‘Key Figures for Belfast, Northern and South Eastern HSC Trusts’ section and relevant charts, as they are not directly comparable with the other Trusts. These figures, sourced from encompass, are considered to be ‘official statistics in development’, which are a subset of Official Statistics in line with the Code of Practice for Statistics. While caution must be exercised when using these figures, they are a meaningful representation of what they measure and are of sufficient quality for publication and use.
This statistical release presents information on waiting times for admission for inpatient or day case treatment in Northern Ireland and reports on the performance of the Health and Social Care (HSC) Trusts against the draft waiting time target, which states that:
“55% of patients should wait no longer than 13 weeks for inpatient/day case treatment; with no patient waiting longer than 52 weeks.”
Information is detailed on the number of patients waiting and length of time waiting by HSC Trust and specialty.
All of the data contained in this release are published in Excel file format to facilitate secondary analysis. They are available at the following link:
Throughout this report comparisons are made to the previous quarter (31 December 2024), to the same date last year (31 March 2024), and to five years ago (31 March 2020).
Statistics in this report refer to the number of patients waiting and the length of time they had been waiting as at the reporting date. They do not indicate completed waiting times or expected future waiting times.
Key Figures for Southern and Western HSC Trusts
Inpatient and Day Case Waiting Times
31,458 patients were waiting for inpatient or day case admission to hospitals in the Southern and Western HSC Trusts on 31 March 2025, 9.3% (3,232) fewer than on 31 December 2024 (34,690), and 27.4% (11,896) fewer than on 31 March 2024 (43,354).

Key Figures for Belfast, Northern and South Eastern HSC Trusts
Inpatient and Day Case Waiting Times
The figures provided for the Belfast, Northern and South Eastern HSC Trusts, sourced from encompass, are considered to be ‘official statistics in development’. Therefore, caution must be exercised when using these figures.
71,175 patients were waiting for inpatient or day case admission to hospitals in the Belfast, Northern and South Eastern HSC Trusts on 31 March 2025.
52.5% of patients were waiting for admission under the Orthopaedics, Gastroenterology, General Surgery or Ophthalmology specialties.
The median waiting time was 35.9 weeks.
The 95 percentile waiting time was 319.8 weeks.
67.4% (47,977) of patients were waiting more than 13 weeks for admission (please note that these figures were revised on 13 June as part of the ongoing validation of encompass data).
42.9% (30,505) of patients were waiting more than 52 weeks for admission (please note that these figures were revised on 13 June as part of the ongoing validation of encompass data).
Inpatient and Day Case Waiting List
Figures in this section do not include the Belfast, Northern or South Eastern HSC Trusts. The previously published time series which includes all Trusts up to 30 September 2023 has, however, been included in Figure 1 to provide context.
On 31 March 2025, there were 31,458 patients waiting for inpatient or day case admission to hospitals in the Southern and Western HSC Trusts.
The number of patients waiting has decreased by 9.3% (3,232) from 31 December 2024 and by 27.4% (11,896) from 31 March 2024.
Figure 1: Patients Waiting for an Inpatient or Day Case Admission in Southern and Western HSC Trusts
30 June 2007 to 31 March 2025
The solid line in Figure 1 shows that the number of patients waiting in Southern and Western Trusts, which rose steadily from 15,257 on 30 September 2013 to 52,678 on 31 March 2023. It has since decreased to 31,458 on 31 March 2025.
Waiting List by Specialty
Figures for the Belfast, Northern and South Eastern Trusts are reported separately in Figure 2b.
On 31 March 2025, the largest waiting lists in Southern and Western HSC Trusts were for T&O Surgery (33.0%, 10,381 patients) and General Surgery (16.2%, 5,107 patients).
Of specialties with at least 500 patients waiting, the greatest proportionate change was in the Ophthalmology specialty which decreased by 64.5% (2,470 patients).
Note that Oral and Maxillofacial Surgery is a new specialty, compared to the historical Oral Surgery specialty in the chart below.
Figure 2a: Patients Waiting for an Inpatient or Day Case Admission by Specialty in Southern and Western HSC Trusts
31 March 2025 compared with 31 March 2024
The bar chart above shows the number of patients waiting for admission under each specialty in the Southern and Western HSC Trusts as at 31 March 2025, with markers comparing numbers as at 31 March 2024. Only specialties with at least 500 patients waiting are shown.
The figures provided for Belfast, Northern and South Eastern HSC Trusts, sourced from encompass, are considered to be ‘official statistics in development’. Therefore, caution must be exercised when using these figures.
Note that the specialty classification used in encompass differs significantly from that of the legacy system. Therefore, specialties are no longer comparable with pre-encompass data or what is currently reported for the Southern and Western Trusts.
On 31 March 2025, the largest waiting lists in the Belfast, Northern and South Eastern HSC Trusts were for Orthopaedics (18.6%, 13,222 patients) and Gastroenterology (15.9%, 11,303 patients).

31 March 2025
The bar chart above shows the number of patients waiting for admission under the top 15 specialties in the Belfast, Northern and South Eastern HSC Trusts as at 31 March 2025. Note that this specialty classification differs from that currently used by the Southern and Western Trusts.
Median and 95th Percentile Waiting Times
Figures in this section do not include the Belfast, Northern or South Eastern HSC Trusts. Data for the Belfast, Northern and South Eastern Trusts are reported separately in the ‘Key Figures for Belfast, Northern and South Eastern HSC Trusts’ section.
The median waiting time is the middle value when all patients are ordered by length of time waiting. This is preferred over the mean as an average of waiting times because waiting times tend to be skewed by longer waits and therefore more patients are waiting for less time than the mean.
The 95th percentile waiting time is the waiting time that 95% of patient waiting times are less than. One in twenty patients i.e. 5%, have been waiting longer than this time. The 95th percentile is used as an indication of the range of current waiting times without being distorted by extreme values or the prioritisation of urgent waits.
On 31 March 2025, the median waiting time for all patients in the Southern and Western HSC Trusts was 50.6 weeks and the 95th percentile was 301.5 weeks (approximately 5 years and 41 weeks).
Figure 3: Median and 95th Percentile Waiting Times in Southern and Western HSC Trusts
30 June 2007 to 31 March 2025
The solid line in Figure 3 shows that the median waiting time in the Southern and Western HSC Trusts increased gradually from 7.1 weeks at 30 September 2014 to 28.1 weeks at 31 March 2020. There was then a sharp increase to 70.3 weeks on 30 June 2021 and since then a gradual decrease to 50.6 weeks on 31 March 2025.
The 95th percentile has increased steadily from 31.1 weeks at 30 September 2014 to 301.5 weeks on 31 March 2025.
Waiting Times by Specialty
Figures for the Belfast, Northern and South Eastern Trusts are reported separately in Figure 4b.
There is a large variation in median and 95th percentile waiting times across different specialties. Low medians relative to the 95th percentile can be an indication of large numbers of patients recently joining a list or a greater proportion of urgent patients within a specialty.
Figure 4a: Median and 95th Percentile Waiting Times by Specialty in Southern and Western HSC Trusts
31 March 2025
The bar chart above shows the median and 95th percentile waiting times for specialties in the Southern and Western HSC Trusts where at least 500 patients were waiting for admission at 31 March 2025. The longest median waiting time was 77.0 weeks in the T&O Surgery specialty.
One in twenty (5%) patients waiting for ENT, General Surgery, Urology, T & O Surgery, Gastroenterology or General Medicine admissions had been waiting over 5 years.
The figures provided for Belfast, Northern and South Eastern HSC Trusts, sourced from encompass, are considered to be ‘official statistics in development’. Therefore, caution must be exercised when using these figures.
Figure 4b: Median and 95th Percentile Waiting Times by Specialty in Belfast, Northern and South Eastern HSC Trusts
31 March 2025
The bar chart above shows the median and 95th percentile waiting times for specialties in the Belfast, Northern and South Eastern HSC Trusts where at least 500 patients were waiting for admission at 31 March 2025. Please note that this specialty classification differs from that currently used by the Southern and Western HSC Trusts.
The longest median wait was within the Breast Surgery specialty (205.6 weeks).
One in twenty (5%) patients waiting for Plastic Surgery, Breast Surgery or ENT admissions had been waiting over 7 years.
Performance against Targets
Trend information is only available for Southern and Western HSC Trusts.
The draft waiting times target states that 55% of patients should wait no longer than 13 weeks for inpatient/day case treatment; with no patient waiting longer than 52 weeks.
Note that this target was introduced in 2016/17.
Figure 5: Patients Waiting Under 13 Week Target in Southern and Western HSC Trusts
30 June 2016 to 31 March 2025
The line and stacked bar charts above illustrate the percentage and number of patients waiting less than 13 weeks in the Southern and Western HSC Trusts at the end of each quarter between 30 June 2016 and 31 March 2025.
Across this period the target of 55% of patients waiting less than 13 weeks was not achieved, with the lowest proportion under 13 weeks being 10.2% (4,153 of 40,905 patients) on 30 June 2020.
On 31 March 2025, 25.7% of patients (8,075 of 31,458) were waiting less than 13 weeks, an increase from 23.3% (10,083 of 43,354) on 31 March 2024 and a decrease from 29.1% (11,368 of 39,004) on 31 March 2020. The figures given in the text of the previous publication for the position at 31 December 2024 have been revised.
Figure 6: Patients Waiting Over 52 Week Target in Southern and Western HSC Trusts
30 June 2016 to 31 March 2025
The line and stacked bar charts above illustrate the percentage and number of patients waiting over 52 weeks in the Southern and Western HSC Trusts at the end of each quarter between 30 June 2016 and 31 March 2025.
Across this period the target of no patients waiting longer than 52 weeks was not achieved, with the highest proportion over 52 weeks being 61.1% (28,331 of 46,369 patients) at 31 March 2021.
On 31 March 2025, 49.5% of patients (15,574 of 31,458) were waiting longer than 52 weeks, a decrease from 51.2% (22,217 of 43,354) on 31 March 2024 and an increase from 29.5% (11,507 of 39,004) on 31 March 2020. The figures given in the text of the previous publication for the position at 31 December 2024 have been revised.
Performance by HSC Trust
The figures provided here for the Belfast, Northern and South Eastern HSC Trusts have been sourced from encompass and are considered to be ‘official statistics in development’. Therefore, caution must be exercised when using these figures.
Draft target: 55% of patients should wait no longer than 13 weeks and no patient should wait longer than 52 weeks for inpatient or day case treatment.
Data shown in this section indicates the Health and Social Care Trust responsible for a patient’s care. As Day Case Procedure Centres are a regional service with patient records held in both the legacy and encompass systems, they have been reported separately from HSC Trusts.
Figure 7: Waiting Times by HSC Trust and Day Case Procedure Centres
31 March 2025
The proportionate stacked bar chart above breaks down the length of time patients have been waiting by the HSC Trust responsible for their service.
No Trust met the target to have 55% of patients waiting less than 13 weeks, nor the target to have no patients waiting longer than 52 weeks.
Between 25.0% and 25.5% of patients were waiting less than 13 weeks in the Southern and Western HSC Trusts and between 48.8% and 51.1% were waiting longer than 52 weeks.
Between 27.3% and 45.7% of patients were waiting less than 13 weeks in the Belfast, Northern and South Eastern HSC Trusts and between 33.0% and 47.1% were waiting longer than 52 weeks.
Inpatient and Day Case Activity
Please note that in the quarterly waiting time statistics publications for quarter ending 31 March 2025 and subsequent quarters, provisional intpatient attendance data that have historically been included will be suspended. Validated hospital activity information will continue to be published as Accredited Official Statistics at Hospital activity statistics.
Data Sources, Quality and Guidance
Data sources
The sources of the data contained in this release are the HSC Trust’s Patient Administration Systems, encompass and the DoH Inpatient Waiting Times Dataset.
Inpatient / day case admission
Inpatient and day case waiting list data comprise the number of patients waiting for inpatient and day case admission to hospital.
Inpatient admissions are patients admitted electively with the expectation that they will remain in hospital for at least one night.
Day case admissions are patients admitted electively with the expectation that although they may require supervised recovery, they do not require the use of a hospital bed overnight and will return home as scheduled the same day.
Measurement of waiting times
Statistics in this report refer to the number of patients waiting and the length of time they had been waiting as at the reporting date. They do not indicate completed waiting times or expected future waiting times. Waiting time begins from the date the clinician decided to admit the patient.
Patients who cannot attend or miss their appointment have their waiting time recorded from the date they informed the HSC Trust that they could not attend or the date of the missed appointment.
Patients suspended for medical or social reasons as at the reporting date are not included in the statistics. If re-instated, the period of suspension is excluded from the waiting time.
Time bands relate to the number of completed weeks a patient has been waiting for admission. For example, a patient waiting exactly 6 weeks would be included in the 0-6 week time band and a patient waiting 6 weeks and 1 day would be included in the 6-13 week time band.
Reporting patients against Health and Social Care Trusts
A number of inpatient and day case services may not be provided at a patient’s local HSC Trust and instead are provided as centralised services for Northern Ireland.
Patients are reported against the HSC Trust responsible for the service to which they have been referred.
Validated figures for patients reallocated between those HCT Trusts using legacy (pre-encompass) systems and HSC Trusts using the encompass system, were unavailable at the time of publication and are not included.
Day Case Procedure Centres
From February 2019, Day Case Procedure Centres (DPCs) are being introduced to deliver large volumes of non-complex routine surgery.
Patients waiting for specific non-urgent surgical treatments can be referred to a DPC for treatment rather than attend the hospital site they may ordinarily have been referred to.
Patients waiting for admission to a Day Case Procedure Centre are included in these statistics.
As these services are managed on a regional basis, patients are not allocated as waiting at a particular HSC Trust and where a Trust split is used in these statistics, the patients are instead reported separately against Day Case Procedure Centres.
Patients with multiple waits
Some patients will be on more than one waiting list or be on the same waiting list for more than one admission due to having multiple conditions. Such patients are counted more than once depending on how many times they are waiting.
There is a known overlap of patients waiting for diagnostic endoscopies that will be managed as an inpatient/day case admission. These are included in both the inpatient and day case waiting time and diagnostic waiting time figures. Due to the risk of multiple counting, these two sets of data should not be combined to give an estimate of the total number of patients waiting for admission or a diagnostic service.
Patients resident outside Northern Ireland and private patients
Statistics on patients waiting for inpatient and day case admission include patients living outside Northern Ireland and privately funded patients waiting for treatment in Health Service hospitals in Northern Ireland.
Exclusions
Inpatient and day case waiting list figures do not include:
• Patients admitted as emergency cases
• Patients waiting for planned admission i.e. patients given proposed date of admission determined by social or clinical criteria
• Patients undergoing a planned programme of treatment e.g. a series of admissions for chemotherapy
• Patients waiting for admission as a regular day or night attender
• Patients waiting for maternity specialties (except where the intention is to terminate the pregnancy)
• Patients waiting who are currently admitted for another reason
• Patients who are temporarily suspended for medical or social reasons
