Project Summary

In addition to a comprehensive literature review, the researchers have undertaken to develop models for DAA use to be evaluated with the preferred research design of a balanced randomised control trial.

The methodology included:

  • An observation and analysis of the existing systems used in delivering and administering medication in a range of domiciliary and residential care settings.
  • A matched sample of consumers using dosage administration aids (DAAs) was compared with a sample of consumers using other medication management systems.
  • A model for a systems analysis of the procedures used in administering medication in a range of domiciliary and residential care settings was developed.
  • A systems analysis across a range of metropolitan, urban and rural domiciliary and residential care settings from all states in Australia, and outcomes evaluated.
  • Evaluation of the use of DAAs in the community and residential care facility settings using qualitative and quantitative methods, emphasising issues such as time and motion, error rates, wastage, cost effectiveness and satisfaction.

The results identified:

  • which existing systems operate effectively with positive outcomes for the stakeholders (nurses, pharmacists, consumers, and the Commonwealth).
  • potential ways of improving the systems for the further implementation of a cost-effective DAA program;
  • to quantify the benefits (e.g. ease of administration, staff time, peace of mind, wastage reduction) and risks associated with DAAs (e.g. dispensing error rates, demands on pharmacies, consumer resistance), and to advise on guidelines to maximise effectiveness of DAAs; and
  • recommendations on sustainable national program for wider implementation of DAA use by residential care and domiciliary
