Abstract
Objectives
This study aimed to determine the prevalence of continuous polypharmacy and hyperpolypharmacy, determine medications that contribute to continuous polypharmacy, and examine the association between frailty and continuous polypharmacy.
Study design
A prospective study using data from the Australian Longitudinal Study on Women’s Health. Women aged 77–82 years in 2003, and 91–96 years in 2017 were analysed, linking the Pharmaceutical Benefits Scheme data to participants’ survey data.
Main outcome measures
The association between frailty and continuous polypharmacy was determined using generalised estimating equations for log binomial regressions, controlling for confounding variables. Descriptive statistics were used to determine the proportion of women with polypharmacy, and medications that contributed to polypharmacy.
Results
The proportion of women with continuous polypharmacy increased over time as they aged. Among participants who were frail (n = 833) in 2017, 35.9 % had continuous polypharmacy and 1.32 % had hyperpolypharmacy. Among those who were non-frail (n = 1966), 28.2 % had continuous polypharmacy, and 1.42 % had hyperpolypharmacy. Analgesics (e.g. paracetamol) and cardiovascular medications (e.g. furosemide and statins) commonly contributed to continuous polypharmacy among frail and non-frail women. Accounting for time and other characteristics, frail women had an 8% increased risk of continuous polypharmacy (RR 1.08; 95 % CI 1.05, 1.11) compared to non-frail women.
Conclusions
Combined, polypharmacy and frailty are key clinical and public health challenges. Given that one-third of women had continuous polypharmacy, monitoring and review of medication use among older women are important, and particularly among women who are frail.
