Data contained in this publication relate to Health Service commissioned activity at consultant-led outpatient services, either in HSC Hospitals (including virtual appointments) or the Independent Sector, and activity in Integrated Clinical Assessment and Treatment Services (ICATS) during 2021/22. Information is provided on New and Review Attendances, Missed Appointments, Patient Cancellations and Hospital Cancellations. All data are presented by HSC Trust and specialty.
Data detailed in this publication are also available in spreadsheet format to aid secondary analysis, at the following link: https://www.health-ni.gov.uk/publications/hospital-statistics-outpatient-activity-statistics-202122
The chart below can be filtered to view face-to-face, DPC, Virtual or ICATS cancellations and missed appointments for the last five years.
Following an outpatient referral, a patient attends an outpatient appointment to see a consultant, their staff and associated health professionals. Outpatient attendances relate to all appointments with a consultant-led service, irrespective of the location in which the service is provided.
A virtual outpatient appointment is a planned contact by a healthcare professional responsible for the care of a patient for the purposes of clinical consultation, advice and treatment planning. Virtual appointments may take the form of a telephone contact, video-link intervention, an email or a letter.
In February 2019, prototype ‘Regional Assessment and Surgical Centres’ (now known as Day Case Procedure Centres - DPCs) became operational for the surgical treatment of Cataracts and Varicose Veins. Patients waiting for these procedures can now be referred to a DPC for treatment rather than the hospital site they may have been referred to previously.
A ward attendance is an attendance at a ward for the purpose of examination by a consultant. These patients would not normally be admitted to the hospital.
An Independent Sector provider is a private sector healthcare company that is contracted by HSC Trusts in the provision of healthcare or in the support of the provision of healthcare.
Integrated Clinical Assessment and Treatment Services ICATS are provided by integrated multi-disciplinary teams of health service professionals, and provide assessment, treatment and advisory services. These are provided in a variety of primary, community and secondary care settings.
Data in this section relate to the number of appointments cancelled by patients who informed the hospital at least the day before their appointment was scheduled that they ‘could not attend’ (CNA). These appointments may be rescheduled for attendance by another patient. When assessing and comparing appointments cancelled by patients, the standardised rate of patient cancellations should be used. \[\small CNA\;rate = \frac {Number\;of\;cancelled\; appointments} {Number\;of\;attendances + number\;of\;cancelled\;appointments} × 100 \]
Hospital Cancellation rates are an indication of a loss to potential productivity within the Health and Social Care system, as in most cases the patient still requires assessment and will have to be booked into another appointment. When assessing and comparing appointments cancelled by hospitals, the standardised hospital cancellation rate should be used. \[\small hospital\;cancellation\;rate = \frac {Number\;of\;hospital\;cancelled\;appointments} {Number\;of\;attendances + number\;of\;hospital\;cancelled\;appointments} × 100 \]
An outpatient appointment may be cancelled by either the patient or the hospital. Reasons for cancellation are not available for virtual or ICATS appointments.
These data relate to the number of patients who ‘did not attend’ (DNA) their appointment and did not inform the hospital, or informed them on the day the appointment was scheduled. These data are used as an indicator of lost productivity in that the hospital is resourced at that point in time to assess a patient, but the appointment is wasted as the patient fails to attend, or fails to give appropriate notice they can’t attend. This prevents another patient from being seen in the scheduled appointment slot. When assessing and comparing missed appointments, the standardised DNA Rate should be used. \[\small DNA\;rate = \frac {Number\;of\;missed\; appointments} {Number\;of\;attendances + number\;of\;missed\;appointments} × 100 \]
Outpatient Service
An outpatient service is a consultant-led service provided by Health and Social Care Trusts to allow patients to see a consultant, their staff and associated health professionals for assessment in relation to a specific condition. Patients are not admitted into hospital for this assessment. Outpatient services are usually provided during a clinic session (though in some cases patients may be seen on a ward, at a designated virtual clinic or at an existing core clinic) and provide an opportunity for consultation, investigation and minor treatment. Patients normally attend by prior arrangement. consultant-led outpatient attendances can take the form of a face-to-face appointment or a virtual appointment (telephone contact, video-link, an email or a letter). Although a consultant is in overall charge, they may not be present on all occasions that the clinic is held. They must, however, be represented by a member of their team.
Outpatient Appointment
An outpatient appointment is an administrative arrangement enabling patients to see a consultant, their staff and associated health professionals, following an outpatient referral. Outpatient appointments relate to all appointments with a consultant-led service, irrespective of the location in which the service is provided. Ward attendances seen by a consultant are reported separately.
New Attendance
A new attendance is the first of a series or the only attendance at an outpatient service with a consultant or their representative following an outpatient referral. Most referrals will be seen as a consequence of a GP referral request; however, referrals may also be received from a range of other sources.
Review Attendance
A review attendance is an attendance at an outpatient service following; a new outpatient attendance, a previous review attendance, an attendance at an Accident & Emergency unit, a domiciliary visit, or following an inpatient admission, for the same condition. Essentially review appointments are all appointments that are not a first appointment.
Virtual Activity
A virtual outpatient appointment is a planned contact by a healthcare professional responsible for the care of a patient for the purposes of clinical consultation, advice and treatment planning. Virtual appointments may take the form of a telephone contact, video-link intervention, an email or a letter.
Day Case Procedure Centres
In February 2019, prototype ‘Day Case Procedure Centres’ (DPCs) became operational to deliver large volumes of assessments and non-complex routine surgery.
Patients waiting for the surgical treatment of Cataracts and Varicose Veins can now be referred to a DPC for treatment rather than attend the hospital site they may have been referred to previously.
Ward Attendances Seen by a Consultant
A ward attender is a patient who attends a ward for the purpose of examination or treatment by a consultant/doctor or member of their team. These patients would not currently be admitted to the healthcare provider. The care is for the prevention, cure, relief or investigation because of a disease, injury, health problem or other factors affecting their health status, as outlined below -
Independent Sector
An Independent Sector provider is a private sector healthcare company that is contracted by HSC Trusts in the provision of healthcare or in the support of the provision of healthcare.
Independent Sector DNA’s, CNA’s and hospital cancellations are not currently collected by the Department.
Integrated Clinical Assessment and Treatment Services (ICATS)
From 1st April 2010, a number of Integrated Clinical Assessment and Treatment Services (ICATS) were introduced. ICATS is the term used for a range of outpatient services for patients, which are provided by integrated multi-disciplinary teams of health service professionals, including GPs with a special interest, specialist nurses and allied health professionals. They are provided in a variety of primary, community and secondary care settings and they include assessment, treatment, diagnostic and advisory services.
An appointment at ICATS is known as a Tier 2 appointment. These are non consultant-led services. Following ICATS Triage, patients who have not been given either a discharge, advice only or referral incomplete outcome will proceed for either a (i) first outpatient appointment, (ii) a diagnostic test or (iii) an ICATS Tier 2 appointment. Following a first Tier 2 ICATS appointment there are a number of possible outcomes, including a review Tier 2 ICATS appointment or a referral for a first consultant-led outpatient appointment.
ICATS Tier 2 appointments attendances, CNA’s, DNA’s and hospital cancellations are defined similarly to those for consultant-led outpatient services.
Patient Cancellations / Could Not Attend (CNA)
These data relate to the number of appointments cancelled by patients who informed the hospital at least the day before the appointment was scheduled. These appointments may be rescheduled for attendance by another patient. This does not include appointments cancelled as a result of the hospital being notified of the patient’s death.
CNA Rate
When assessing and comparing appointments cancelled by patients, the standardised rate of patient cancellations (CNA Rate) should be used. This is necessary because the number of appointments scheduled is likely to impact upon the number of cancelled appointments.
CNA Rate = (number of cancelled appointments) / (total attendances + number of cancelled appointments) × 100
Hospital Cancellation
This is the number of outpatient appointments that have been cancelled by the providing hospital. A cancelled appointment is one which was intended to be held but which did not occur. In most cases the patient still requires assessment and will be rebooked into another appointment. These data are an indication of the loss of potential productivity within hospitals. This does not include appointments cancelled by the hospital as a result of the patient’s death. These appointments may be rescheduled for attendance by another patient.
Hospital Cancellation Rate
When assessing and comparing appointments cancelled by hospitals, the standardised rate of hospital cancellations should be used. This is necessary because the number of appointments scheduled is likely to impact upon the number of cancelled appointments.
Hospital Cancellation Rate = (number of hospital cancellations) / (number of attendances + number of hospital cancellations) × 100
Reasons for Cancellation
An outpatient appointment may be cancelled by either the providing hospital or the patient.
Hospital Cancellations may occur for the following reasons:
Patient Cancellations (CNA) may occur for the following reasons:
Health and Social Care Trusts must use one of the above regional codes to record reason for cancellation. If no reason for cancellation has been recorded, Trusts report this as ‘No reason for cancellation recorded’.
If an incorrect reason for cancellation has been recorded, for example if one of the hospital cancellation reasons is recorded against a patient cancellation, Trusts report the reasons for such cancellations as ‘Incorrect reason for cancellation recorded’.
Cancellations due to the death of a patient are reported separately and should not be included in figures for either patient or hospital cancellations.
Missed Appointments / Did Not Attend (DNA)
These data relate to the number of patients who did not attend their appointment and did not inform the hospital, or informed them on the day the appointment was scheduled. These data are used as an indicator of lost productivity in that the hospital is resourced at that point in time to assess a patient, but the appointment is wasted as the patient fails to attend, or fails to give appropriate notice that they cannot attend. This prevents another patient from being seen in the scheduled appointment slot.
DNA Rate
When assessing and comparing missed appointments, the standardised rate of missed appointments (DNA Rate) should be used. This is necessary because the number of appointments scheduled is likely to impact upon the number of missed appointments, i.e. the more appointments scheduled, the more likely it will be that the number of missed appointments will increase.
DNA Rate = (Number of missed appointments) / (Total attendances + number of missed appointments) × 100
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 is recorded against the specialty of the treating consultant.
Private Patient Attendance
A private patient is one who has opted to have treatment outside the Health Service and has undertaken to pay for all expenses incurred to attend an assessment with a Health and Social Care consultant at a Health and Social Care facility. Private patient attendances are included within the main outpatient activity figures and are also available separately in the downloadable data files. These columns therefore should not be added together.
Number of Attendances vs Number of Patients
The number of attendances does not equate to the number of patients seen, as it is possible for the same person to attend a consultant-led outpatient service more than once during the year. This is the same when looking at missed and cancelled appointments and the reasons for cancellation, as it is possible for the same person to miss or cancel their appointment or have their appointment cancelled by the hospital more than once during the year.
Impact of Coronavirus (COVID-19) on Outpatient Activity
When interpreting the statistics 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 during the reporting period, including the availability and location of services. This has had a direct impact on the outpatient activity observed.
Data from 2021/22 can be compared with previous years but users should bear in mind that many of the changes observed will be influenced by and attributable to the impact of COVID-19.
This release does not include any specific COVID-19 data.
Data Sources
The information presented in this publication derives from statistical returns (listed below) provided by HSC Trusts, Hospitals and the HSC Board:
Data providers are supplied with technical guidance documents outlining the methodologies that should be used in the collection, reporting and validation of these data returns. These documents can be accessed at the following link: https://www.health-ni.gov.uk/articles/outpatient-activity
Information presented in this publication in relation to the QOAR, R-QOAR, QIAR and V-QOAR returns has been validated and quality assured by HSC Trusts prior to publication. Following submission, Hospital Information Branch perform a series of checks to verify that information is consistent both within and across returns. Trend analyses are used to monitor annual variations and emerging trends. Queries arising from validation checks are presented to HSC Trusts for clarification and if required, returns may be amended and/or re-submitted. Prior to the publication of this information, the data are formally signed off by HSC Trusts.
Face-to-face Activity, Day Case Procedure Centre Activity and Ward Attendances
The data for consultant-led outpatient activity in HSC hospitals (face-to-face outpatient attendances and ward attendances) are compiled from the Quarterly Outpatient Activity Return (QOAR) which was introduced from 1st April 2008. Day Case Procedure Centre data are compiled from the Regional Quarterly Activity Return (R-QOAR) which was introduced from March 2019. The returns refer to all HSC hospitals in Northern Ireland that provide consultant-led outpatient services.
The number of ward attendances missed by the patient or cancelled by either the patient or the hospital is not collected by the Department.
DPC activity data are not national statistics, but have been provided to add some additional context to outpatient activity.
Independent Sector Activity
Independent Sector activity data have been compiled from the Independent Sector Part 1 (IS1 Part 1) Return, which was introduced from 1st April 2008. They refer to all activity that takes place in Independent Sector providers commissioned by the Health Service.
These data are not National Statistics and have not been validated by the Department; however, they have been published to provide users with a comprehensive view of activity commissioned by the Health Service during each year.
Virtual Outpatient Activity
The virtual outpatient activity data has been compiled from the Virtual Outpatient Activity Return (V-QOAR) which was introduced at the beginning of 2015/16.
Prior to 2015/16, virtual outpatient activity was included within the QOAR. During 2015/16, this activity was removed from the QOAR and was not included within this publication in 2015/16, 2016/17 and 2017/18. From 2018/19 onwards, virtual activity is included as a separate category.
Integrated Clinical Assessment and Treatment service (ICATS) Activity
The ICATS activity data contained in this publication have been compiled from the Quarterly ICATS Activity Return (QIAR), which was introduced from 1st April 2010.
Reasons for cancellation of ICATS Tier 2 appointments are not currently collected by the Department.
Private patient attendances
While data providers have been given in-depth guidance providing instructions for recording, collection and submission of data, the information undergoes limited validation. Users should not confuse these data with that for patients transferred by Health and Social Care providers to the Private or Independent Sector for treatment.
Private patient attendances are included within the main outpatient activity figures and also listed separately in the downloadable data files. These columns therefore should not be added together.
Reason for outpatient appointment cancellation
The ‘reason for cancellation’ variable was only made mandatory for completion from March 2013. Data users should be aware of this when comparing data across the years.
Data are derived from a range of administrative systems. The levels of appointments that are either not coded with a reason, or have been coded with an incorrect reason has improved in recent years and therefore users should be careful in their use of the data. Increasing levels of coverage over time presents complexities whereby, for example, a reported increase in the number of appointments cancelled due to the consultant being unavailable, may be a consequence of better levels of coding in latter quarters rather than an actual increase in the number of appointments cancelled for this reason. Due to changes in coding coverage, care should be taken when comparing the number of appointments cancelled for a particular reason over time.
Almost all of the patients with no reason recorded are in the Belfast HSC Trust. The Belfast HSC Trust holds the highest proportion of manual records, which typically do not have a reason provided.
Readers should note that not all hospital cancellations will necessarily result in a negative impact for the patient.
