Queensland Hospital Admitted Patient Data Collection (QHAPDC):
AN-SNAP classification is calculated by SSB.
The AN-SNAP is a resource utilisation classification for sub-acute and non-acute patients based on patient functioning, diagnosed conditions, demographic characteristics of the patient and usage of hospital resources.

The AN-SNAP classification groups episodes of care into one of five care types - palliative care, rehabilitation care, psychogeriatric care, geriatric evaluation and management or maintenance care. Within the five care types, episodes are further grouped based on specified criteria such as phase of care, patient functioning and age.

The development of the AN-SNAP classification has created a descriptive framework for studying sub-acute care hospitalisation. AN-SNAP provides a summary of the type and complexity of sub-acute patients a hospital treats. As a framework for describing the products of a hospital (that is, patients receiving services), AN-SNAP allows meaningful comparison of hospitals' efficiency and effectiveness under alternative systems of health care provision.

The first digit of the AN-SNAP class code reflects the AN-SNAP classification version number.
