Evaluating the Modified Barthel Index for Policy and Practice in Reablement: Lessons From Australia's Short-Term...

Area of Science:

• Gerontology
• Rehabilitation Medicine
• Health Services Research

Background:

• The Modified Barthel Index (MBI) is mandated by the Australian Government for the Short-Term Restorative Care program (STRC).
• Assessing functioning and self-care ability is crucial for older adults in reablement programs.

Purpose of the Study:

• To evaluate the suitability of the MBI as an outcome measure for functioning and self-care in the Australian aged care reablement context.
• To identify limitations of the MBI in capturing meaningful changes in participants of the STRC program.

Main Methods:

• Retrospective cohort study of 921 participants in the STRC program (January 2018 - March 2023).
• Comparison of STRC responders and non-responders using MBI scores and demographic variables.
• Application of Generalised Linear Modelling to assess MBI's utility in informing intervention delivery.

Main Results:

• The MBI indicated significant baseline differences between responders and non-responders, potentially influenced by sample size.
• A notable ceiling effect was observed with the MBI in the studied older adult population.
• The MBI's capacity to guide evidence-based modifications to program delivery was found to be limited.

Conclusions:

• The study highlights the limitations of relying solely on the MBI for outcome measurement in aged care reablement.
• Findings support the need for a broader range of standardized assessments tailored to individual participant goals.
• Recommendations are provided for implementing more comprehensive assessment strategies in future aged care programs, including the Restorative Care Pathway.
