National Ability Supports System (NASS)

Data Collection Type
National data collections of health and social care in Ireland
Organisation

National Health Information Systems Unit of the Health Research Board (HRB).

The HRB and Health Service (HSE) Executive are joint controllers of NASS data.

Year established

In 2019 NASS replaced the National Intellectual Disability Database (NIDD, established 1995) and the National Physical and Sensory Disability Database (NPSDD, established 2002). NASS is one of four national health information systems managed by the HRB’s National Health Information Systems Unit and hosted on the Unit’s web-based platform, LINK.

Statement of purpose

To collect data on the HSE-funded disability services that people use or require in a 5-year period.

New services provided to service users aged over 65 years are out of scope as these are managed by HSE Older Persons’ rather than Disability services.

Coverage (geographical and temporal)

National.
NASS data collection is carried out on an annual basis.

National-level identifier variables

Equity stratifiers

Sex, age, employment status, ethic/cultural background, type of living accommodation are captured by NASS.

Data collection methodology

Trained users within HSE and non-HSE organisations who provide HSE disability-funded services record information about their service users and the services they receive or require in the web-based system. Each user record is reviewed annually.

Data may be recorded manually or uploaded to the system in a file containing multiple records.

The data collection period runs from January/February to end December each year.

Clinical coding scheme

No formal clinical coding/ disease classification scheme is used. Currently diagnoses are coded using a coding system based on ICD-10.

A move to the SNOMED terminology is planned.

Size of national collection

Each annual dataset contains approximately 36,000 existing or newly registered records.

Publication frequency

Reports are published annually and are available on the HRB website, www.hrb.ie.
