National Disability Insurance Scheme timeframes and functional outcomes for inpatient rehabilitation patients: a 5-year retrospective audit

Abstract

Objective The aim of this study was to compare National Disability Insurance Scheme (NDIS) timeframes and functional outcomes for a patient population managed in an inpatient hospital rehabilitation unit. Methods A retrospective hospital audit was undertaken of adult patients admitted to a tertiary-level, regional inpatient rehabilitation unit between January 2017 and December 2021 who were either referred, or not, to the NDIS. A hospital NDIS patient database, Australasian Rehabilitation Outcome Centre episode data, and patient medical records were analysed. The main outcome measures included actual rehabilitation length of stay versus expected length of stay, and Functional Independence Measure (FIM) efficiency for all inpatients, with NDIS timeframes analysed for the NDIS-referred patient subgroup. Results Rehabilitation inpatients referred for NDIS services significantly exceeded expected rehabilitation length of stay compared to those not referred to the NDIS. Furthermore, expected length of stay was significantly exceeded for those patients who required implementation of a NDIS plan to safely transition from hospital. FIM efficiency was significantly lower for patients referred to the NDIS. Recent improvement in timeframes for being accepted as a NDIS participant did not reduce length of stay. Conclusions NDIS timeframes for rehabilitation inpatients incur a significant opportunity cost for the provision of efficient inpatient rehabilitation services that are unaccounted for in current benchmarking performance standards.
