Attitudes towards deprescribing and the influence of health literacy among older Australians.

The 137 responses showed that 80% thought all their medications were necessary and were comfortable with the number taken. Wanting to reduce the number of medications taken was associated with concerns about the amount taken (P<0.001), experiencing side effects (P<0.001), or believing that one or more medications were no longer needed (P<0.000). Those who were using ten or more medications were more likely to want to reduce the number taken (P=0.019). Most (88%) respondents would be willing to stop medication/s in the context of receiving this advice from their doctor. Willingness to consider stopping correlated with higher scores on the critical health literacy subscale (P<0.021) and overall AAHLS score (P<0.009). Those with higher scores on the overall AAHLS measure were more likely to report that they understood why their medications were prescribed (P<0.000) and were more likely to participate in decision-making (P=0.027). Opportunities to proactively consider deprescribing may be missed, as one third of the respondents could not recall a recent review of their medications.
