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 in Northern HSC Trust on 7 November 2024, and its rollout across the other Trusts will continue in 2025. Consequently, as South Eastern and Belfast HSC Trusts continue to transition to completely digitised health records, diagnostic test reporting turnaround data for these Trusts were not available at the time of publication.

The diagnostic waiting times data which it has been possible to include for South Eastern and Belfast HSC Trusts have been presented separately, 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.

Charts and figures presented throughout this report have, therefore, excluded patients waiting for a diagnostic test or diagnostic test report in the South Eastern and Belfast HSC Trusts 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.


A diagnostic service provides an examination, test, or procedure used to identify a person’s disease or condition and which allows a medical diagnosis to be made. There are three categories of diagnostic test: Imaging test; Physiological Measurement test; and Day Case Endoscopy.

This statistical release presents information on waiting and reporting times for diagnostic services in Northern Ireland and reports on the performance of the Health and Social Care (HSC) Trusts against the draft waiting and reporting times targets which state that:

  • 75% of patients should wait no longer than 9 weeks for a diagnostic test, with no patient waiting longer than 26 weeks.
  • all urgent diagnostic tests should be reported on within two days of the test being undertaken.

All of the data contained in this release are published in CSV or Excel file format to facilitate secondary analysis, including additional breakdowns by HSC Trust, weeks waiting and reporting times. The data are available at the following link:

Key Figures

Diagnostic Waiting Times

Figures in this section do not include the South Eastern and Belfast HSC Trusts, as data for these Trusts are reported separately in the ‘Key Figures for South Eastern and Belfast HSC Trusts’ section.

  • 123,067 patients were waiting for a diagnostic test in the Northern, Southern and Western HSC Trusts, 1.1% (1,390) more than on 30 June 2024 (121,677), and 18.9% (19,564) more than on 30 September 2023 (103,503).

  • 63.2% (77,810) of patients were waiting more than 9 weeks for a diagnostic test, compared with 61.4% (74,713) on 30 June 2024 and 53.9% (57,257) on 30 September 2023.

  • 38.6% (47,551) of patients were waiting more than 26 weeks for a diagnostic test compared with 35.2% (42,828) on 30 June 2024 and 25.5% (27,036) on 30 September 2023.

Diagnostic Reporting Turnaround Times

Figures in this section do not include the South Eastern and Belfast HSC Trusts, as data were not available as at 31 December 2023 and later dates for South Eastern HSC Trust, or as at 30 June 2024 and later dates for Belfast HSC Trust.

  • 260,319 diagnostic tests were reported on at hospitals in the Northern, Southern and Western HSC Trusts during the quarter ending September 2024. Of these, 30.3% (78,960) were urgent tests and the remaining 69.7% (181,359) were routine tests.

  • Of the 78,960 urgent diagnostic tests, 78.4% (78,960) were reported on within 2 days.

Key Figures for South Eastern and Belfast HSC Trusts

Diagnostic Waiting Times

Pure Tone Audiometry data sourced from encompass currently account for appointments differently to legacy (pre-encompass) data and are higher than in previous quarters.

  • 94,968 patients were waiting for a diagnostic test in the South Eastern and Belfast HSC Trusts.

  • 64.7% (61,481) of patients were waiting more than 9 weeks for a diagnostic test.

  • 43.4% (41,177) of patients were waiting more than 26 weeks for a diagnostic test.

Diagnostic Waiting List

On 30 September 2024, there were 123,067 patients waiting for a diagnostic test in the Northern, Southern and Western HSC Trusts.

The number of patients waiting increased by 1.1% (1,390) since 30 June 2024 (121,677) and increased by 18.9% (19,564) since 30 September 2023.

Figures in this chart do not include the South Eastern and Belfast HSC Trusts, which are reported separately in the ‘Key Figures for South Eastern and Belfast HSC Trusts’ section.

This line chart shows that the number of patients waiting has risen steadily from 31,186 on 30 September 2013 to 123,067 on 30 September 2024.

Diagnostic Waiting List by Service

Figures in this section do not include the South Eastern and Belfast HSC Trusts, which are presented separately in Figure 2b.

On 30 September 2024, the largest waiting lists were for Non-Obstetric Ultrasound (25,952 patients, 21.1% of the waiting list) and Magnetic Resonance Imaging (18,366 patients, 14.9% of the waiting list).

Echocardiography, Plain Film X-Rays, Pure Tone Audiometry and Computerised Tomography - General each also account for over 5.0% of the waiting list.

Of services with more than 2,000 patients waiting, Non-Obstetric Ultrasound had the greatest proportionate increase with 50.5% (8,706) more patients waiting on 30 September 2024 (25,952) than on 30 September 2023 (17,246).

Performance Against Waiting Times Target

Figures in this section do not include the South Eastern and Belfast HSC Trusts, which are reported separately in the ‘Key Figures for South Eastern and Belfast HSC Trusts’ section.

The draft diagnostic waiting times target states that 75% of patients should wait no longer than 9 weeks for a diagnostic test, with no patient waiting longer than 26 weeks.

This target was introduced in 2016/17.

Figure 3: Patients Waiting Under 9 Week Target

30 June 2016 to 30 September 2024

The line and stacked bar charts above illustrate the percentage and number of patients waiting less than 9 weeks for a diagnostic test between 30 June 2016 and 30 September 2024.

Across this period the target of 75% of patients waiting less than 9 weeks was not achieved, with the highest proportion under 9 weeks being 73.0% (36,020 of 49,346 patients) on 30 June 2016.

On 30 September 2024, 36.8% (45,257 of 123,067 patients) were waiting less than 9 weeks for a diagnostic test, a decrease from 41.4% (42,871 of 103,503 patients) on 30 September 2023.

Figure 4: Patients Waiting Over 26 Week Target

30 June 2016 to 30 September 2024

The line and stacked bar charts above illustrate the percentage and number of patients waiting longer than 26 weeks for a diagnostic test between 30 June 2016 and 30 September 2024.

Across this period the target of no patients waiting longer than than 26 weeks was not achieved, with the lowest proportion over 26 weeks being 3.9% (1,913 of 49,346 patients) on 30 June 2016.

On 30 September 2024, 38.6% (47,551 of 123,067 patients) were waiting longer than 26 weeks for a diagnostic test, an increase from 30.0% (31,012 of 103,503 patients) on 30 September 2023.

Diagnostic Tests Reported

Figures in this section do not include the South Eastern and Belfast HSC Trusts, as data were not available as at 31 December 2023 and later dates for South Eastern HSC Trust, or as at 30 June 2024 and later dates for Belfast HSC Trust.

Exclusions From This Analysis

Data on diagnostic reporting is currently only collected by the Department of Health for a subset of imaging and physiological measurement tests. Day case endoscopies are reported on the day of the test and are therefore excluded.

Although statistics in this section can be considered as a general indicator of reporting performance, they do not represent all patients coming off waiting lists above.


There were 260,319 diagnostic tests reported on during the quarter ending 30 September 2024, of which 30.3% (78,960) were urgent tests and the remaining 69.7% (181,359) were routine tests.

The total number of tests reported decreased by 2.7% (7,203) from 267,522 during the quarter ending 30 June 2024 and increased by 9.2% (24,563) from 235,756 reported in the quarter ending 30 September 2023.

The proportion of urgent tests remained comparable to the 30.3% during the quarter ending 30 June 2024 and increased from 28.6% during the quarter ending 30 September 2023.

Figure 5: Diagnostic Tests Reported by Urgency

Quarter Ending June 2015 to Quarter Ending September 2024

The stacked bar chart above illustrates the number of tests reported and the number classified as urgent between June 2015 and September 2024.

Aside from a large drop in the number of tests reported during the four quarters from June 2020 to March 2021, the number of tests reported each quarter has risen gradually from 201,554 during the quarter ending June 2015 to 260,319 during the quarter ending September 2024.

The number of urgent tests reported has risen steadily from 26,910 during the quarter ending June 2015 to 78,960 during the quarter ending September 2024. The proportion of tests classified as urgent rose gradually from 13.4% (26,910 of 201,554) in the quarter ending June 2015 to 19.5% (43,737 of 223,934) in the quarter ending March 2020. There was a sharp increase to 27.4% (34,911 of 127,616) in quarter ending June 2020, largely attributable to a decrease in the number of routine tests reported. Since then, the proportion of urgent tests has continued to increase, with 30.3% (78,960 of 260,319) reported in quarter ending September 2024.

Performance Against Reporting Times Target

Figures in this section do not include the South Eastern and Belfast HSC Trusts, as data were not available as at 31 December 2023 and later dates for South Eastern HSC Trust, or as at 30 June 2024 and later dates for Belfast HSC Trust.

Exclusions From This Analysis

Data on diagnostic reporting turnaround times is currently only collected by the Department of Health for a subset of imaging and physiological measurement tests. Day case endoscopies are reported on the day of the test and are therefore also excluded.

Although statistics in this section can be considered as a general indicator of reporting performance, they do not represent all patients coming off waiting lists above.


The draft reporting target states that all urgent diagnostic tests should be reported on within 2 days of the test being undertaken.

This target was introduced in 2012/13.

Of the 78,960 urgent diagnostic tests reported during the quarter ending September 2024, 78.4% (61,896) were reported on within 2 days.

Figure 6: Urgent Diagnostic Tests Reported Within 2 Day Target

Quarter Ending June 2015 to Quarter Ending September 2024

The line and stacked bar charts above illustrate the percentage and number of urgent diagnostic tests reported on within 2 days between the quarter ending June 2015 and the quarter ending September 2024.

The target has not been met at any point during this period.

The percentage of urgent tests reported within 2 days has decreased gradually from 87.8% during the quarter ending June 2015 (23,620 of 26,910) to 78.4% (61,896 of 78,960) during the quarter ending September 2024. The highest percentage reported across this period was 93.7% during the quarter ending June 2020.

Data Sources, Quality and Guidance


Data sources

The sources for the data contained in this release are the quarterly Departmental SDR1 and DRTT returns.

SDR1 returns detail diagnostic waiting times and are provided by each of the Health and Social Care Trusts. Diagnostic reporting turnaround time information is detailed in the DRTT return also provided by the Health and Social Care Trusts.

HSC Trusts use the Northern Ireland Picture Archive and Communications System (NIPACS) as the mechanism for managing imaging services. Strategic Planning and Performance Group in the Department of Health has carried out a validation exercise with Trusts to address any data quality issues.

Data for the South Eastern HSC Trust from 9 November 2023 onwards and for the Belfast HSC Trust from 6 June 2024 onwards are sourced from ‘encompass’, which is a new electronic patient record system. The data are considered to be ‘official statistics in development’. The system also went live in Northern HSC Trust on 7 November 2024, and its rollout across the other Trusts will continue in 2025.


Diagnostic service

A diagnostic service provides an examination, test, or procedure used to identify a person’s disease or condition and which allows a medical diagnosis to be made. There are three categories of diagnostic test: Imaging test; Physiological Measurement test; and Day Case Endoscopy.


Diagnostic waiting times

The diagnostic waiting time relates to all tests with a diagnostic element. Included are tests that are part diagnostic and subsequently part therapeutic. A therapeutic procedure is defined as a procedure which involves actual treatment of a person’s disease, condition or injury. Patients currently admitted to a hospital bed and waiting for an emergency procedure, patients waiting for a planned procedure, patients waiting for procedures as part of screening programmes, and purely therapeutic procedures are excluded from the waiting times target and from this analysis.

The waiting time for a diagnostic service commences on the date on which the referral for the service is received by the Health Care provider and stops on the date on which the test is performed. Patients who cannot attend have their waiting time recorded from the date they informed the HSC Trust that they could not attend, while patients who miss their appointment have their waiting time adjusted to commence on the date of the missed appointment. Time bands shown relate to the number of completed weeks a patient has been waiting for a diagnostic service. 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 (greater than 6 weeks but waiting no longer than 9 weeks) time band. This also applies to the number of days waited for a diagnostic turnaround.

Some patients will be on more than one waiting list or be on the same waiting list for more than one diagnostic test due to having multiple conditions. Such patients are counted more than once depending on how many times they are waiting.


Diagnostic reporting turnaround times

The diagnostic reporting turnaround time is the time interval between the completion of the diagnostic test and the results of that test being verified or dispatched to the referring clinician in Northern Ireland, whichever is applicable.

Diagnostic reporting times apply to a selected subset of imaging and physiological measurement diagnostic services. These services are: Magnetic Resonance Imaging; Computerised Tomography; Non-Obstetric Ultrasound; Barium Studies; DEXA Scan; Radio-Nuclide Imaging; Pure Tone Audiometry; Echocardiography; Perfusion Studies; Peripheral Neurophysiology; Sleep Studies; and Urodynamics Pressures and Flows and Plain Film X-rays. Day case endoscopies are reported on the day of the test and are, therefore, excluded from diagnostic reporting times.


Comparisons over time

Two major changes in the data collection of diagnostic waiting lists and diagnostic reporting times occurred in 2010/11 and 2015/16 respectively. Prior to 2010/11, diagnostic waiting information was collected and presented relating to 16 selected diagnostic services, after which the department commenced collection of waiting times data for all diagnostic services. From 2015/16 Plain Film X-Rays were included in reporting data.

Due to these changes, it is only possible to provide trend data from 2010/11 onwards for diagnostic waiting lists and from 2015/16 onwards for diagnostic reporting times.

Figures for reporting years prior to these are still published in the accompanying CSV files, however users should exercise caution in how they are used and are advised against making any comparisons that cross these time points.


Comparison across HSC Trusts

A number of diagnostic services may not be provided at all of the five HSC Trusts in Northern Ireland. In this situation, patients from one HSC Trust area will be waiting to be seen at a service provided at another HSC Trust. Users should therefore be cautious in how they use these data. For example, they should not be used to calculate the total number of patients waiting per head of the population residing within each HSC Trust area. Neither should the actual number of patients waiting longer than the recommended waiting time be used as an indicator of poor performance within an individual HSC Trust. Users who require an indication of the latter are advised to refer to the commentary section of the publication which provides an indication of the percentage of total waiters that have been waiting over the maximum recommended waiting times, within each HSC Trust.


Inpatient or day case admission for diagnostic tests

A number of the diagnostic services, particularly endoscopies, reported on the SDR1 returns are managed as an admission: either an inpatient admission or a day case. As such, they will be 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

The diagnostic waiting times and diagnostic reporting turnaround times returns (SDR1 Parts 1 and 2, DRTT) include patients living outside Northern Ireland and privately funded patients waiting for diagnostic services in Health Service hospitals in Northern Ireland.


Data quality and revisions

The information on diagnostic waiting and reporting times contained within this publication is currently under review. The Department is considering how this information is sourced and the validation procedures that are carried out with a view to improving the quality. All quality issues identified as part of this review are being addressed on an ongoing basis.

The Department of Health’s policy is to publish revised figures with subsequent statistical releases unless it is decided that the magnitude of the change merits earlier notification.

Due to technical issues, data for cardiology physiological measurement diagnostic tests from the Royal Belfast Hospital for Sick Children have not been available since February 2020. The impact of this on the statistics in this report is minimal. At February 2020, there were 321 patients waiting for this service, this was approximately 7% of the total waiting for Belfast HSC Trust’s cardiology service.
