Multiple anticholinergic medication use and risk of hospital admission for confusion or dementia

This cohort study of 36,015 Australian veterans identified an association between the use of multiple medicines with anticholinergic effects and the rate of hospitalisation due to confusion and dementia, with an IRR of:

  • 2.58 for patients taking two medicines with anticholinergic effects
  • 3.87 for patients taking three or more medicines with anticholinergic effects.

Barriers and facilitators to reducing anticholinergic burden: a qualitative systemic review

A systematic review of studies exploring barriers and facilitators to reducing anticholinergic burden in the Australian healthcare system.

It found that studies exploring patient and carer perspectives are currently absent but are required to ensure person-centred care and feasibility of future interventions.

Weir et al. 2020

Pharmacists’ and older adults’ perspectives on the benefits and barriers of Home Medicines Reviews – a qualitative study

This Australian study highlights the barriers to an effective Home Medicines Review (HMR), including gaps in inter-professional communication and factors relating to patient involvement, such as limited medicines understanding and health literacy.

White et al. 2012

Consumer perspectives of the Australian Home Medicines Review program: benefits and barriers

This study investigates Australian patients’ perceived benefits and barriers regarding HMRs from 14 focus groups.

It concluded that promotion of HMRs would increase patient uptake, and communicating the process/benefits clearly and sensitively would obviate consumer misconceptions and/or barriers.
