This publication presents information on inpatient and day case consultant-led activity at the five Health and Social Care Trusts in Northern Ireland during the year ending 31 March 2025. It details information on Available Beds, Occupied Beds, Occupancy Rates, Average Length of Stay, Theatre Activity and Hospital Births. Data are presented by HSC Trust, Hospital, Programme of Care and Specialty as appropriate. Data detailed in this publication are also available in spreadsheet format (Microsoft Excel) to aid secondary analysis, at the link: https://www.health-ni.gov.uk/publications/hospital-statistics-inpatient-and-day-case-activity-202425.

Data Warning

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.

Figures sourced from encompass for South Eastern, Belfast and Northern HSC Trusts 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.


As of November 2025, the following publication has been updated to include data from Northern HSC Trust, following the Trust’s transition to completely digitised health records using the encompass system.

Total Admissions

Please note that on encompass, transfers within an HSC Trust are no longer treated as a new admission. This may result in a decrease to the number of admissions reported.

During 2024/25 there was a total of 524,457 admissions to hospitals in Northern Ireland.

This was a decrease of 25,389 (4.6%) from 549,846 in 2023/24. Over half (52.9%, 277,316) were day case admissions while the remaining 47.1%, (247,141) were inpatient admissions.

There was an increase of 96,725 (22.6%) on the number admitted in 2020/21 (427,732).

Admissions by HSC Trust

As shown in Figure 3a, Belfast HSC Trust had the highest number of admissions during 2024/25, accounting for 29.1% (152,419) of the total admissions. This was followed by 19.7% (103,159) in Western HSC Trust, 18% (94,384) in South Eastern HSC Trust, 17.2% (90,320) in Southern HSC Trust, and 16% (84,175) in Northern HSC Trust. For Trust trends over time please see Figure 3b on the second chart tab.

Data users should be aware that not all inpatient services are provided at each of the HSC Trusts in Northern Ireland. In some circumstances patients from one HSC Trust area will be admitted to another HSC Trust. It is therefore not possible to accurately calculate the number of inpatient admissions per head of the population in any HSC Trust area, as HSC Trusts that provide services for the whole of Northern Ireland will have a higher number of admissions per head of the population than those which provide more localised services.

During 2024/25, Western HSC Trust had the highest occupancy rate of all five trusts at 89%, while the lowest rate of occupancy was in the Belfast HSC Trust at 82%.

Commissioned Beds and Escalation Spaces

With the move to encompass, it is now possible to count both commissioned beds (funded) and escalation spaces (temporary spaces used only to cope with demand or increased pressures) within wards that are open overnight.

Escalation spaces are counted as those in excess of the number of commissioned beds per quarter. This provides some context as to the capacity and demands within each hospital during the year.

Please note, prior to 1 March 2025, South Eastern HSC Trust escalation spaces were identified and tagged as such, rather than simply being a count in excess of the commissioned beds.

Chart

Figure 5 (above): bar chart illustrating the total number of days occupied in commissioned beds and escalation spaces by hospital in 2024-2025. Figures for hospitals in Belfast and Northern HSC Trusts are counted only since the launch of encompass within their respective Trusts.

Table

Throughput

Throughput is a measurement of the average number of inpatient admissions treated in each available bed open overnight each year. There has been an overall increase in throughput, from 40 admissions per bed in 2020/21 to 42.4 admissions per bed in 2024/25.

Chart

Table

Average Length of Stay

Average length of stay in hospitals increased from 6.4 days in 2020/21 to 7.4 days in 2024/25.

Please note, on encompass, transfers within an HSC Trust are no longer treated as a new admission. Therefore, when compared with previous years, there may be a decrease in the number of inpatients recorded and the average length of stay may be longer.

Table

In 2024/25, Belfast HSC Trust had the longest average length of stay with 8.1 days, followed by South Eastern HSC Trust with 7.8 days. Western HSC Trust had the shortest with 6.7 days. The location of regional specialties such as cardiac surgery, thoracic surgery and forensic psychiatry in the Belfast HSC Trust may explain the longer average length of stay.

Use of Operating Theatres

Data users should note that ‘Use of Operating Theatres’ statistics are not designated as Accredited Official Statistics.

Information in relation to the use of operating theatres is presented by session type, hospital and HSC Trust. The use of operating theatres relates to the number of cases operated on by National Confidential Enquiry into Patient Outcome and Death (NCEPOD) classification.

Theatre cases are classified as Immediate, Urgent, Expedited or Elective. In 2024/25, there were 104,848 theatre cases across the five HSC Trust hospitals in Northern Ireland; this was a decrease of 1% (1,074) compared with 105,922 theatre cases in 2023/24.

Across all Programmes of Care, the number of cases operated on was highest in Belfast HSC Trust, with 33.4% (35,024) of all theatre usage. Northern Trust had the lowest use of operating theatres with 10.8% (11,320).

Across all HSC Trusts, Elective cases accounted for 73% of all theatre activity, followed by 14.9% of cases recorded as Urgent, 10.3% as Expedited and 1.8% as Immediate.

Chart

Table

During 2024/25, the top 5 specialties on the legacy system accounted for 35.9% (37,672) of all theatre activity. The highest number of cases in Northern Ireland was recorded under General Surgery with 12%, followed by Trauma & Orthopaedics 8.6%, Urology 6%, Obs & Gyn (Gynaecology) 4.8% and Obs & Gyn (Obstetrics) with 4.7% of all theatre cases.

During 2024/25, the top 5 specialties on encompass accounted for 24.1% (25,234) of all theatre activity. The highest number of cases in Northern Ireland was recorded under Urology with 5.8%, followed by Ophthalmology 4.9%, Orthopaedic Elective 4.7%, General Surgery 4.7% and Gynaecology with 4% of all theatre cases.

Note, specialties in the legacy and encompass systems cannot be directly compared. Specialties in the legacy system were recorded using Korner codes, based on the main specialty of the lead consultant, while specialties in encompass use Hospital Services, based on what the patient is being treated for. These also do not map on a 1-1 basis, i.e. they are two different lists of specialty levels.

Of all 104,848 theatre cases, 90.3% (94,672) were under the Acute Programme of Care.

Acute Programme of Care

Total Admissions

Please note that on encompass, transfers within an HSC Trust are no longer treated as a new admission. This may result in a decrease to the number of admissions reported.

During 2024/25 there was a total of 466,686 admissions to hospitals in Northern Ireland under the Acute programme of care accounting for approximately 89% of all admissions in 2024/25. Admissions decreased by 18,362 (3.8%) on the 485,048 admitted in 2023/24. There was an increase of 101,562 (27.8%) on the 365,124 admitted in 2020/21.

Admissions by HSC Trust

In 2024/25, 53.1% of admissions to hospital under the acute programme of care in Belfast HSC Trust were either elective (13.6%) or day case (39.4%) admissions. This is the highest proportion for any of the five HSC Trusts. Of all the admissions to Southern HSC Trust in 2024/25, 4.8% were elective. This is the smallest proportion of elective admissions in any of the five HSC Trusts presented in this publication.

Table

Admissions by Specialty

In 2024/25, 9.3% of all admissions to hospital under the acute programme of care were under the Nephrology specialty in the legacy system, with 8.9% of admissions under General Medicine, 6% General Surgery, 3.2% Haematology (Clinical) and 3.1% Cardiology. Within encompass, 6.2% of all admissions within the acute programme of care were under the Gastroenterology specialty, 6.1% of admissions under General Internal Medicine, 6% Renal Medicine, 2.6% Urology and 2.5% Cardiology.

Note, specialties in the legacy and encompass systems cannot be directly compared. Specialties in the legacy system were recorded using Korner codes, based on the main specialty of the lead consultant, while specialties in encompass use Hospital Services, based on what the patient is being treated for. These also do not map on a 1-1 basis, i.e. they are two different lists of specialty levels.

Day Case Rate

The day case rate is given as a percentage of elective admissions (including day cases and elective inpatients).

The day case rate returned to 82.6% in 2024/25, after being higher since 2021/22. The greatest change occurred between 2020/21 and 2021/22 when the day case rate increased from 82.6 % to 84.3% of all elective admissions.

A method of reducing excess bed days and pre-operative length of stay is to increase the use of day case surgery for procedures such as tonsillectomies, cataract extractions and varicose vein removal where it is clinically safe to do so.

Chart

Table

Within the acute programme of care, Northern HSC Trust had a day case rate of 89% in 2024/25 which was the highest of the five HSC Trusts. Belfast HSC Trust had the lowest day case rate with 74.3% of elective admissions recorded as day cases. However, this may be explained by the provision of specialised regional services by the Belfast HSC Trust and on occasion, the higher numbers of complex cases.

Bed Availability and Occupancy

Between 2023/24 and 2024/25 there was a decrease of 5.4% (237) in the average number of available beds in the acute programme of care from 4,352.3 to 4,115.3 beds. In the period between 2020/21 and 2024/25, the average available beds increased by 163.8 from 3,951.5 to 4,115.3.

During 2024/25 there was an average of 3,548.7 occupied beds. This was a decrease of 98.3 bed days (2.7%) on the 3,647 during the previous year, and an increase of 889.4 bed days (33.4%) on the number of occupied beds in 2020/21.

The occupancy rate for acute specialties in hospitals in Northern Ireland was 86.2% during 2024/25; this was an increase from 83.8% in 2023/24.

Figure 21 (above): line chart illustrating the average length of stay in the acute programme of care in each HSC Trust in 2024-2025.

Table

During 2024/25 in the legacy system, the longest average length of stay across all acute specialties in Northern Ireland was under the Infectious Diseases specialty where admissions lasted for an average of 29.4 days. The shortest average length of stay was under the Paediatric Dentistry specialty where admissions lasted for an average of 0.7 days.

During 2024/25 in encompass, the longest average length of stay across all acute specialties in Northern Ireland was under the Rehabilitation Medicine specialty where admissions lasted for an average of 43.1 days. The shortest average length of stay was under the Dental Medicine specialty where admissions lasted for an average of 0.8 days.

Please note, the specialty of Oral Surgery was reclassified in some hospitals during the 2023/24 year to Oral and Maxillofacial Surgery.

Average length of stay by specialty can only be approximated. Although occupied bed days accurately reflect the specialty that a patient was in at the midnight count, the number of inpatients is measured using deaths and discharges, and therefore a patient may have spent multiple nights under another specialty before the one from which they are finally discharged.

Acute Services in the Independent Sector

Data users should note that ‘Acute Services Independent Sector Activity’ statistics are not designated as Accredited Official Statistics.

An Independent Sector provider is a private sector healthcare company that is contracted by the HSC Trust in the provision of healthcare or in the support of the provision of healthcare. All Independent Sector admissions occurred within the Acute Programme of Care.

In 2024/25 there were 23,537 admissions to hospitals in Northern Ireland for an inpatient or day case procedure with an Independent Sector provider that was commissioned by the Health Service. This was a decrease of 1,245 (5%) when compared with 2023/24 but an increase of 14,972 (174.8%) when compared with 2020/21.

Maternity and Child Health Programme of Care

Admissions under the maternity and child health programme of care accounted for 7.8% of all admissions in 2024/25.

Only consultant-led admissions are counted on the KH03A statistical monitoring return. Please note, Western Trust’s figures include midwife-led admissions, as this cannot be separated out. Similarly, prior to 2022/23, Southern Trust Maternity and Child Health figures included midwife-led admissions and beds.

Please note, in the downloadable data file where details are provided per hospital, Causeway Hospital’s Maternity services were moved to Antrim Area Hospital from July 2023.

Total Admissions

Please note that on encompass, transfers within an HSC Trust are no longer treated as a new admission. This may result in a decrease to the number of admissions reported.

In 2024/25 there were 40,873 admissions to hospitals in Northern Ireland under the maternity and child health programme of care, a decrease of 2,233 (5.2%) when compared with 2023/24 and a decrease of 1,330 (3.2%) when compared with 2020/21. The greatest change in maternity and child health admissions was from 2023/24 (43,106) to 2024/25 (40,873).

Bed Availability and Occupancy

The average number of available beds increased by 9.7% from 404.5 in 2023/24 to 443.6 in 2024/25. Average occupied beds decreased from 233.8 to 230.5 over the same period. Average available beds were 4.9% higher (20.8) in 2024/25 than in 2020/21, with average occupied beds rising by 10.4% from 208.8 to 230.5.

Of the 443.6 average available beds in Northern Ireland in 2024/25, 27.3% (121.2) were located in South Eastern HSC Trust. Northern HSC Trust had the smallest percentage of available beds, with 14.5% (64.2).

The occupancy rate for maternity specialties in hospitals in Northern Ireland was 52% during 2024/25; this is a decrease from the 57.8% in 2023/24, but an increase from 49.4% in 2020/21.

Please note, South Eastern HSC Trust’s move to encompass means that available beds now include excess cot capacity for multiple births, and therefore available bed figures have increased.

Hospital Births

Data users should note that ‘Hospital Births’ statistics are not designated as Accredited Official Statistics.

Hospital Births statistics relate only to births that occurred, either while admitted to an HSC Trust Hospital in Northern Ireland; or while en route to an HSC Trust hospital, immediately prior to admission. Therefore, these figures do not reflect the number of home births in Northern Ireland, and are not comparable to Birth Registrations data.

The total number of births in hospital in Northern Ireland decreased by 3.9% (782) from 19,826 births in 2023/24 to 19,044 births in 2024/25. Between 2020/21 and 2024/25 total births decreased by 2,487, from 21,531 in 2020/21.

Technical Notes

Data Collection and Quality

All information presented in this bulletin has been provided by HSC Trusts or downloaded by Hospital Activity Information Branch (HAIB) from an electronic patient-level administrative system within an agreed timescale and quality assured by HAIB prior to release.

Queries arising from validation checks are presented to HSC Trusts for clarification and if required, returns may be amended. Once complete, all figures are sent to HSC Trusts for final sign-off.

Trend analyses are used to monitor annual variations and emerging trends.

Trusts which went live on the new encompass system throughout the year will have provided data both from legacy systems and encompass at the time of their move. South Eastern HSC Trust were fully transitioned onto encompass by 2024/25, while Belfast HSC Trust moved on 6 June 2024, and Northen HSC Trust moved on 7 November 2024.


Data Considerations:

  • When interpreting the time series presented in this report, consideration should be given to the impact of the coronavirus (COVID-19) pandemic on hospital services. Users should be aware that the pandemic drastically altered the functions of hospitals particularly during 2020/21, including the availability and location of services. This has had a direct impact on the activity observed during that year.
  • Data from 2024/25 can be compared with previous years, but users should bear in mind that some of the changes observed from 2020/21 will be influenced by and attributable to the impact of COVID-19.


Data providers are supplied with technical guidance documents outlining the methodologies that should be used in the collection, reporting and validation of each of these data returns. These documents can be accessed at the following link:

https://www.health-ni.gov.uk/articles/inpatient-and-day-case-activity

It is not possible to accurately identify ambulatory care pathway activity, and as such this activity has been excluded from this publication. Similarly, use of virtual wards within Emergency Care Departments has been excluded from this publication. Patient transfers within the same Trust were counted as multiple admissions within the legacy system, but now on encompass are recorded as a transfer and therefore only one admission and discharge.

The data for individual hospitals on certain indicators (e.g. ‘Average Available Beds’) will not always sum to the HSC Trust total or the overall NI total due to rounding. In addition, certain indicators (e.g. ‘Throughput’) have been derived from unrounded figures for greater accuracy. They may therefore differ slightly from values obtained through using rounded figures in the formulae. Percentages have been rounded to one decimal place and therefore totals may not sum to 100.

Main Uses of Data

The main uses of these data are to monitor inpatient and day case activity, to help assess Trust performance, for corporate monitoring, to inform and monitor related policy, and to respond to parliamentary/assembly questions and ad-hoc queries.

Inpatient and Day Case Activity Information Elsewhere in the United Kingdom

Inpatient and day case activity information is available for elsewhere in the UK, however, users should be aware that this data in other administrations is not always measured in a comparable manner to Northern Ireland.

Definitions

1. Programme of Care

Activity and occupied beds on the legacy system has been grouped into POCs on the basis of the main specialty of the consultant in charge of the patient at the time of discharge. In a small number of cases, this may lead to differences between the strict POC and the specialty of the consultant in charge.

On encompass, activity and occupied beds are now grouped based on the Treatment Function Code (TFC) which is then mapped up to POC. This measures what the patient was being treated for at the time of the count (discharge for activity, and midnight for occupied beds). Available beds are mapped to a POC using the department specialty which is allocated by each HSC Trust based on the bed’s physical location in a ward. Mixed wards could not be catered for in reporting and therefore where a ward has more than one POC, beds were allocated to a single POC meaning small numbers of beds may be assigned to a different POC.


2. Inpatients

Inpatient admissions include both (a) patients admitted electively with the expectation that they will remain in hospital for at least one night, and (b) non-elective admissions (e.g. emergency admissions). A patient who is admitted with the intention of staying overnight, but who leaves hospital for any reason without staying overnight is still counted as an inpatient. Day cases and regular attenders are not included. Inpatients are approximated using deaths and discharges and therefore counted within the time period of their discharge, and under their final specialty before discharge. On encompass, transfers within the same HSC Trust are no longer counted as multiple admissions as they were within the legacy system, but are recorded as a transfer and therefore only one admission and discharge. With encompass transfers, patients are counted under the hospital of their first admission. Please note, encompass transfers to a community programme of care are not included and this whole admission will not be counted due to current report developments.


3. Day Case

A patient admitted electively during the course of a day with the intention of receiving care who does not require the use of a hospital bed overnight and who returns home as scheduled. If this original intention is not fulfilled, and the patient stays overnight, such a patient should be counted as an inpatient. Regular attenders have been included within the day case statistics for all programmes of care but presented separately for the acute programme of care.


4. Admissions

Total admissions has been taken to be the sum of all day cases, inpatients (elective and non-elective) and regular attenders. Deaths and discharges have been used as an approximation for admissions. Admissions are counted within the time period of their discharge, and under their final specialty before discharge. Only consultant-led activity is included.


5. Average Available/Occupied Beds

The average number of available and occupied beds during the year in wards that are open overnight, measured at midnight. Beds reserved for day care admission or regular day admission are not included. Previous to encompass, occupied beds were counted under the main specialty of the lead consultant at the time of the count, however, in encompass, they are counted under the Treatment Function Code (TFC) that the patient is being treated for at the time of the count. In encompass, escalation spaces are now included in the total occupied bed count. Only beds used for consultant-led care are included.


6. Percentage Occupancy

A measurement of the percentage of time that beds are occupied. Beds reserved for day cases and regular attenders are not included in the calculation. Note: In exceptional circumstances, the number of average occupied beds may exceed the number of average available beds. This can be due to both patient management and/or recording methods. With encompass, it is now possible to present both commissioned beds and escalation spaces used within each POC.

Occupancy (%) = (Average Daily Occupied Beds) / (Average Daily Available Beds) × 100


7. Commissioned Bed

A commissioned bed is one with full recurrent funding for all direct, indirect and overhead costs associated with the provision of the bed.


8. Escalation Space

An escalation space is a space in addition to the commissioned allocated bed complement that is used on a short-term temporary basis to cope with demand or increased pressures. An escalation space may also be known as an additional, contingency, flex or extra space. The term space is preferred as opposed to bed as it may not be a physical bed per se.


9. Throughput

A measurement of the average number of inpatient admissions treated in each available bed open overnight each year. Day Cases and regular attenders are excluded from the calculation, as well as beds reserved for their use throughout the day. Where small values of average available and average occupied beds have resulted in a throughput value greater than 365, this has been set to ‘-’, as 365 is the maximum possible value of throughput (or 366 on a leap year).

Throughput = (Total Inpatients) / (Average Available Beds)


10. Average Length of Stay

A measurement of the average length of time spent in hospital. Day Cases and regular attenders are excluded from the calculation, as well as beds reserved for their use throughout the day. Note: The calculation of average length of stay assumes that patients spend the entire length of their stay in hospital within the same specialty as they were discharged from. On occasions, patients may be transferred between specialties during the same stay in hospital. In these circumstances, such transfers may slightly skew the average length of stay at a specialty level.

Average Length of Stay = (Average Daily Occupied Beds x Days in Year) / (Total Inpatients)


11. Elective Inpatient

A patient for whom the decision to admit could be separated in time from the actual admission. This excludes emergency admissions and maternity or delivery episodes.


12. Non-Elective Inpatient

A patient for whom admission is unpredictable and at short notice because of clinical need.


13. Regular Day/Night Attender

A patient who is admitted electively and regularly for a planned sequence of days or nights and who returns home for the remainder of the 24 hour period. This method of admission is particularly common for Renal Dialysis and Chemotherapy. Regular attenders have been included within the day case statistics for all programmes of care, with the exception of acute services.


14. Day Case Rate

The number of day cases given as a percentage of elective inpatients.

Day Case Rate = (Total Day Cases) / (Total Elective Inpatients + Total Day Cases) × 100


15. Specialty

A specialty is a particular branch of medicine or surgery. Each consultant is assigned a main specialty from a list recognised by the Royal Colleges and Faculties. Information on the legacy system is recorded against this main specialty of the leading consultant. On encompass, data is recorded against the Treatment Function Code (TFC), or what the patient was being treated for. For admissions, they are recorded under the main specialty or TFC at their time of discharge.


16. Use of Operating Theatres

It is not possible to split cases operated on under the obstetrics specialty in Altnagelvin Hospital into the 4 National Confidential Enquiry into Patient Outcome and Death (NCEPOD) classifications, therefore all non-elective cases are reported under the urgent category. Information relating to availability and use of operating theatres excludes the following: - Obstetric delivery room containing a delivery bed; - Dental treatment room or surgery containing a dental chair; - X-ray room, whether diagnostic or therapeutic; - Room only used to carry out endoscopy. Nurse-led activity and Cardiology Cath Lab activity are also excluded. From 2024/25, independent sector activity is also excluded from this section. From 2024/25, cases are counted as one visit to the operating theatre, regardless of the number of separate procedures carried out on the patient during this visit.


17. Immediate

Immediate life, limb or organ-saving intervention – resuscitation simultaneous with intervention. Normally within minutes of decision to operate. a) Life-saving b) Other e.g. limb or organ saving


18. Urgent

Intervention for acute onset or clinical deterioration of potentially life-threatening conditions, for those conditions that may threaten the survival of limb or organ, for fixation of many fractures and for relief of pain or other distressing symptoms. Normally within hours of decision to operate.


19. Expedited

Expedited patient requiring early treatment where the condition is not an immediate threat to life, limb or organ survival. Normally within days of decision to operate.


20. Elective

Elective intervention planned or booked in advance of routine admission to hospital. Timing to suit patient, hospital and staff.


21. Acute Services Independent Sector Activity

This is the number of health service patients who were admitted for acute inpatient or day case treatment with an Independent Sector provider. An Independent Sector provider is a private sector healthcare company that is contracted by the HSC Trust in the provision of healthcare or in the support of the provision of healthcare.


22. Live/Still Birth

A birth can be classified as ‘live’ or ‘still’. A still birth is where, after a gestation period of at least 24 weeks, the baby shows no identifiable signs of life at delivery. Figures relate to only those births that occurred within a hospital, i.e. home births are not included.

Data in the publication

The data contained in this publication are presented on an annual basis. They represent inpatient and day case consultant-led activity at inpatient services at Health and Social Care (HSC) hospitals in Northern Ireland and Independent Sector providers. This publication refers to all acute, maternity, elderly care, mental health and learning disability hospitals.


Inpatient Activity by Admission Method, Specialty, Hospital, HSC Trust, Programme of Care (POC)

Description of data

Data are presented on the number of available and occupied beds and inpatient admissions in Northern Ireland. Data are presented by the HSC hospital of admission, which are then aggregated up to HSC Trust, in Northern Ireland.

Acute data are split by admission method into elective inpatient, non-elective inpatient, day case and regular attenders. The sum of the elective inpatients and non-elective inpatients totals the number of inpatients. Similarly, the sum of the day cases and the regular attenders equals the total number of day cases within the acute POC.

Non-acute data are split by admission method into inpatient and day case admissions. Patients who are treated at an accident and emergency department but are not subsequently admitted are not included.


Data provider

Available and occupied beds for all programmes of care and non-acute activity data are sourced via the legacy departmental return KH03a, and the HSC KH03a - Available & Occupied Bed Days, Discharges & Day Cases report on encompass. Acute activity data are sourced from the Hospital Inpatient System whose data originates from the legacy Patient Administration System (PAS) through the Business Objects Data Warehouse, and the HSC IP Activity report on encompass.

Guidance on using data

Average Available/Occupied Beds – this is the number of available and occupied beds during the year in wards that are open overnight, counted at midnight.

Specialty – this is the number of admissions within each medical speciality. Medical specialty on the legacy system is determined by the consultant in charge of the treatment of the patient. Each consultant employed by an HSC Trust will have an allocated specialty of employment, and it will be this specialty against which the patient’s admission will be reported. On encompass, medical specialty is measured using the Treatment Function Code (TFC) which looks at what the patient is being treated for.

Programme of Care (PoC) – this relates to the number of admissions or bed days within each Programme of Care which is a classification that aggregates specialties on the basis of the type of health care they provide, into a higher level classification. This is mapped up from the Department Specialty for available bed days, main specialty of the lead consultant for occupied bed days and admissions on the legacy system, and the Treatment Function Code (TFC) for occupied bed days and admissions on encompass.


Use of Operating Theatres, by Session Type, Hospital, HSC Trust and Programme of Care

These are not Accredited Official Statistics.

Data provider - Theatre Management System through the legacy Business Objects Data Warehouse, and the Use of Operating Theatres by Hospital report on encompass.

Guidance on using data

Cases Operated On – These data provide insight into the usage of theatre resources by different specialties.


Acute Independent Sector Inpatient Admissions by Appointment Type, Specialty and HSC Trust

Description of data

This relates to the number of health service patients who were admitted for an acute inpatient procedure with an Independent Sector provider. Data are presented by specialty and commissioning HSC Trust (the HSC Trust responsible for the patient’s waiting time), in Northern Ireland. These are not Accredited Official Statistics.

Data provider - Departmental Return IS1 Part 2 by the Strategic Performance and Planning Group (SPPG), which is responsible for the regional commissioning of independent sector provision, and the HSC IS2: Inpatients Treated in the Independent Sector report on encompass.

Guidance on using data

Independent Sector provision is introduced when the demand for certain types of inpatient service is greater than the capacity within HSC hospitals. When this situation results in increases in both the number of patients waiting and the length of time waiting, patients may be admitted for a procedure undertaken by an Independent Sector provider. The cost of treating these patients is met by the transferring HSC Trust.


Number of Live and Still Births in Hospital and Type of Delivery by Hospital, HSC Trust

Description of data

Data on the number of births in HSC Hospitals in Northern Ireland. Data are split by both live and still births and method of delivery and presented by hospital and type of unit. These are not Accredited Official Statistics.

Data provider - Northern Ireland Maternity System (NIMATS) through the legacy Business Objects Data Warehouse, and the Maternity and Child Health Number of Live and Still Births in Hospital by Trust/Hospital report on encompass.

Guidance on using data

This relates to the number of births in hospital (home births are not included), and provides information on which HSC Trusts have the highest numbers of births.

Accredited Official Statistics

Accredited Official statistics are called National Statistics in the Statistics and Registration Service Act 2007. These official statistics were independently reviewed by the Office for Statistics Regulation in June 2013. They comply with the standards of trustworthiness, quality and value in the Code of Practice for Statistics and should be labelled ‘accredited official statistics’

It is a producer’s responsibility to maintain compliance with the standards expected of Accredited Official Statistics. If we become concerned about whether these statistics are still meeting the appropriate standards, we will discuss any concerns with the Authority promptly. Accredited Official Statistics status can be removed at any point when the highest standards are not maintained, and reinstated when standards are restored.

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. You are welcome to contact us directly with any comments about how we meet these standards.
