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 HSC Trust on 6 June 2024 and its rollout across the other Trusts will follow on a phased basis throughout 2024/25. Consequently, as South Eastern HSC Trust continues to transition to completely digitised health records, not all of their data were available at the time of publication. Given the relatively recent transition of Belfast Trust, no data were available for this Trust at the time of publication.

The data which it has been possible to include for South Eastern HSC Trust, have been presented in a separate ‘Key Figures for South Eastern HSC Trust’ section and relevant charts, as they are not directly comparable with the other Trusts. The figures provided for this Trust, sourced from encompass, are considered to be ‘official statistics in development’. Therefore, caution must be exercised when using these figures.

Charts and figures presented throughout this report, with the exception of the previously mentioned ‘Key Figures for South Eastern HSC Trust’ section and relevant charts, exclude patients waiting for a first outpatient appointment in the Belfast and South Eastern HSC Trusts. This is to allow comparisons to be made for the three remaining HSC Trusts over previous years. As such, any Northern Ireland level figures throughout this report only include data for Northern, Southern and Western HSC Trusts.


This statistical release presents information on waiting times for a first consultant-led outpatient appointment in Northern Ireland and reports on the performance of the Health and Social Care (HSC) Trusts against the draft waiting times target, which states that:

“50% of patients should wait no longer than nine weeks for a first outpatient appointment; 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. Provisional statistics on outpatient activity are also included.

All of the data contained in this release are published on the NISRA Data Portal and in XLSX format to facilitate secondary analysis. These are available at the following links:

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.

Outpatient Waiting List

Figures in this section do not include the South Eastern or Belfast HSC Trusts. Data for South Eastern HSC Trust are reported separately in the ‘Key Figures for South Eastern HSC Trust’ section. Validated data for Belfast HSC Trust were not available at the time of publication. The previously published time series including all Trusts up to 30 September 2023 has, however, been included in Figure 1 to provide context.

As at 30 June 2024, there were 230,530 patients waiting for a first consultant-led outpatient appointment at hospitals in the Northern, Southern and Western Trusts.

The number of patients waiting has decreased by 1.6% (3,810) from 31 March 2024 and increased by 9.4% (19,792) from 30 June 2023.


Figure 1: Patients Waiting for a First Consultant-led Outpatient Appointment

30 June 2008 to 30 June 2024

This line chart shows that the number of patients waiting has risen steadily from 44,149 on 31 March 2013 to 230,530 on 30 June 2024.

Waiting List by Specialty

Figures in this section do not include the South Eastern or Belfast HSC Trusts. Data for South Eastern HSC Trust are reported separately in the ‘Key Figures for South Eastern HSC Trust’ section and Figure 2b. Validated data for Belfast HSC Trust were not available at the time of publication.

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 Northern, Southern and Western Trusts.

At 30 June 2024, the largest waiting lists were for General Surgery (36,787 patients) and ENT (32,856 patients).

Of specialties with at least 5,000 patients waiting, the greatest proportionate growth was in the Oral and Maxillofacial Surgery specialty, which grew by 115.7% (3,801 patients). The greatest proportionate reduction was in the Ophthalmology specialty, with 17.3% (2,232) fewer patients.


Figure 2a: Patients Waiting for a First Consultant-led Outpatient Appointment by Specialty

30 June 2024 compared with 30 June 2023

The bar chart above shows the number of patients waiting for an appointment in each specialty as at 30 June 2024, with markers comparing numbers as at 30 June 2023. Only specialties with at least 5,000 patients waiting are shown.

The figures provided for the South Eastern HSC Trust, sourced from encompass, are considered to be ‘official statistics in development’. Therefore, caution must be exercised when using these figures.

At 30 June 2024, the largest waiting lists were for ENT (14,989 patients) and Gynaecology (13,077 patients).


Figure 2b: Patients Waiting for a First Consultant-led Outpatient Appointment by Specialty at South Eastern Trust

30 June 2024

The bar chart above shows the number of patients waiting for an appointment at the South Eastern HSC Trust in each specialty as at 30 June 2024. Only specialties with at least 5,000 patients waiting are shown. Note that this specialty classification differs from that currently used for the Northern, Southern and Western Trusts.

Median and 95th Percentile Waiting Times

Figures in this section do not include the South Eastern or Belfast HSC Trusts as validated data were not available at the time of publication.

Exclusions From This Analysis

Paedaetrics, Genito-Urinary Medicine, Learning Disability and Old Age Psychiatry specialties are excluded from this analysis due to limited data availability.

Information required to produce this analysis is not available prior to 30 June 2020.


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 length of time that 95% of patients have been waiting equal to or less than i.e. one in twenty patients 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.

At 30 June 2024, the median waiting time for a first outpatient appointment was 55.7 weeks and the 95th percentile was 263.4 weeks (approximately 5 years and 3 weeks).


Figure 3: Median and 95th Percentile Waiting Times

30 June 2020 to 30 June 2024

This line chart shows that the median waiting time has increased from 40.1 weeks at 30 June 2020 to a peak of 59.3 weeks at 31 December 2021 then decreased to 55.7 weeks at 30 June 2024. The 95th percentile waiting time has increased steadily from 158.1 weeks at 30 June 2020 to 263.4 weeks at 30 June 2024.

Waiting Times by Specialty

Figures in this section do not include the South Eastern or Belfast HSC Trusts as validated data were not available at the time of publication.

Exclusions From This Analysis

Paedaetrics, Genito-Urinary Medicine, Learning Disability and Old Age Psychiatry specialties are excluded from this analysis due to limited data availability.


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 4: Median and 95th Percentile Waiting Times by Specialty

30 June 2024

The bar chart above shows the median and 95th percentile waiting times for specialties where at least 5,000 patients were waiting for appointments at 30 June 2024. The longest median waiting time was 99.4 weeks in the Oral and Maxillofacial Surgery specialty.

Neurology, Oral and Maxillofacial Surgery , Rheumatology, General Surgery, Thoracic Medicine, Haematology (Clinical), Pain Management, Ophthalmology and Gynaecology specialties all had median waiting times over 1 year.

At least one in twenty (5%) patients waiting for Neurology, Oral and Maxillofacial Surgery , Urology, Rheumatology, General Medicine, Geriatric Medicine, Gastroenterology, General Surgery, Dermatology or Thoracic Medicine had been waiting over 5 years.

Performance against Targets

Figures in this section do not include the South Eastern or Belfast HSC Trusts. Data for South Eastern HSC Trust are reported separately in the ‘Key Figures for South Eastern HSC Trust’ section. Validated data for Belfast HSC Trust were not available at the time of publication.

The draft waiting times target states that 50% of patients should wait no longer than 9 weeks for a first consultant-led outpatient appointment; with no patient waiting longer than 52 weeks.

This target was introduced in 2016/17.


Figure 5: Patients Waiting Under 9 Week Target

30 June 2016 to 30 June 2024

The line and stacked bar charts above illustrate the percentage and number of patients waiting less than 9 weeks 30 June 2016 to 30 June 2024.

Across this period the target of 50% of patients waiting less than 9 weeks was not achieved, with the highest proportion under 9 weeks being 39.2% (36,045 of 92,045 patients) at 30 June 2016.

As at 30 June 2024, 15.8% of patients were waiting less than 9 weeks, a decrease from 17.4% at 30 June 2023 and a decrease from 27.7% at 30 June 2019.

Figure 6: Patients Waiting Over 52 Week Target

30 June 2016 to 30 June 2024

The line and stacked bar charts above illustrate the percentage and number of patients waiting over 52 weeks from 30 June 2016 to 30 June 2024.

Across this period the target of no patients waiting longer than 52 weeks was not achieved, with the highest proportion over 52 weeks being 54.8% (92,730 of 169,201 patients) at 31 March 2021.

At 30 June 2024, 50.8% of patients were waiting longer than 52 weeks, an increase from 47.6% at 30 June 2023 and an increase from 30.2% in 30 June 2019.

Performance by HSC Trust

Figures in this section do not include the Belfast HSC Trust as validated data for it were not available at the time of publication. The figures provided here for South Eastern HSC Trust 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: 50% of patients should wait no longer than 9 weeks and no patient should wait longer than 52 weeks for a first consultant-led outpatient appointment.

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, they have been reported separately from HSC Trusts.


Figure 7: Waiting Times by HSC Trust and Day Case Procedure Centres

30 June 2024

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 50% of patients waiting less than 9 weeks, nor the target to have no patients waiting longer than 52 weeks.

Outpatient Activity

Provisional Statistics

Outpatient attendance data are fully validated once per year. Statistics in this section are subject to revision in subsequent releases and do not hold National Statistics status.

Fully validated outpatient activity statistics are published annually at the following link:

https://www.health-ni.gov.uk/articles/outpatient-activity


Figures in this section do not include the South Eastern or Belfast HSC Trusts. Data for South Eastern HSC Trust are reported separately in the ‘Key Figures for South Eastern HSC Trust’ section. Validated data for Belfast HSC Trust were not available at the time of publication.

Between 01 April and 30 June 2024, there were 56,468 attendances at first outpatient appointments, of which 1.4% (807) were at independent sector providers commissioned by HSC Trusts and the remaining 98.6% (55,661) at HSC Trust hospitals.


Figure 8: Number of First Outpatient Attendances Commissioned by HSC Trusts

Quarter Ending June 2008 to Quarter Ending June 2024

The bar chart above indicates the number of patients who attended first outpatient appointments in each quarter between June 2008 and June 2024. The number of patients attending remained steady from 2008 to March 2020. A sharp decrease was observed in June 2020 and since then activity has risen steadily and has almost returned to prior levels.

ICATS Waiting List

Integrated Clinical Assessment and Treatment Services (ICATS) are outpatient services provided by multi-disciplinary teams of health service professionals. They provide assessment, treatment and advisory services in a variety of primary, community and secondary care settings. Patients who do not require urgent treatment are referred to ICATS teams, if the patient’s condition requires the attention of a consultant, arrangements are made for the patient to be referred for a hospital outpatient appointment.

As ICATS services are not consultant-led, patients waiting for an ICATS appointment are not included in the statistics for consultant-led outpatient services presented in the sections above.


Figures in this section do not include the South Eastern or Belfast HSC Trusts. Data for South Eastern HSC Trust are reported separately in the ‘Key Figures for South Eastern HSC Trust’ section. Validated data for Belfast HSC Trust were not available at the time of publication.

At 30 June 2024, there were 16,241 patients waiting for a first ICATS outpatient appointment. The number of patients waiting has increased by 6.0% (926) from 31 March 2024 and increased by 8.4% (1,256) from 30 June 2023.


Figure 9: Patients Waiting for a First ICATS Outpatient Appointment

30 June 2011 to 30 June 2024

This line chart shows that the number of patients waiting for a first ICATS outpatient appointment rose steadily from 4,165 on 30 June 2011 to 16,241 on 30 June 2024.

Data Sources, Quality and Guidance

Data sources
The sources for the data contained in this release are the HSC Trust’s Patient Administration Systems, encompass, the DoH Outpatient Waiting Times Dataset and the DoH CH3, QOAR, R-QOAR, V-QOAR and IS1 returns.


First consultant-led outpatient appointment
An outpatient appointment is to enable a patient to see a consultant or a member of their team following an outpatient referral. The majority of referrals will be from a GP however they may also be received from a range of other sources.

These appointments provide an opportunity for consultation, investigation and minor treatment. Appointments can be face-to-face or virtual and patients are not admitted into hospital.

A first attendance is the first of a series or the only attendance at an outpatient service.


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 for a first outpatient appointment begins on the date the HSC Trust receives a referral to a consultant-led service.

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 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 6-9 week time band.


Reporting patients against Health and Social Care Trusts
A number of services may not be provided at a patient’s local HSC Trust, and instead are provided as centralised services for Northern Ireland.

As patients are reported against the HSC Trust responsible for the service to which they have been referred, users should be aware of this when making comparisons across Trusts.

In some cases a consultant from one HSC Trust may provide a “visiting” service at another HSC Trust, and so the patient may not be reported at the HSC Trust at which they attend. Patients are reported against the HSC Trust responsible for the service to which they have been referred.


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 an outpatient appointment at 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 appointment due to having multiple conditions. Such patients are counted more than once depending on how many times they are waiting.


Patients resident outside Northern Ireland and private patients
Statistics on patients waiting for outpatient appointments include patients living outside Northern Ireland and privately funded patients waiting for treatment in Health Service hospitals in Northern Ireland.


Outpatient activity
Provisional statistics on outpatient activity are presented to provide contextual information in relation to waiting lists. Hospital data are sourced from the HSC Trusts and Independent Sector data are provided by the Strategic Planning and Performance Group in the Department of Health.

These data are not Accredited Official Statistics and have not been validated or quality assured by HSC Trusts prior to publication. Data quality is addressed on an ongoing basis and figures are subject to revision in subsequent publications as hospital records may not be fully up to date as at the publication date.

Provisional statistics on outpatient activity do not include:
• ICATS appointments
• Ward attenders
