Learning from an epidemiological, population-based study on prescribed medicine use in adults

Area of Science:

• Public Health
• Pharmacology
• Gerontology

Background:

• Prevalence of prescribed medicine use is a key indicator of population health and healthcare utilization.
• Understanding trends in medication use is crucial for effective healthcare planning and resource allocation.

Purpose of the Study:

• To examine changes in the prevalence of prescribed medicine use in Australian community-based adult populations between 2004 and 2008.
• To identify demographic and therapeutic group-specific trends in medication consumption.

Main Methods:

• Face-to-face interviews were conducted with random, representative samples of South Australian adults aged 15 years and older in 2004 and 2008.
• Data collected included self-reported use of prescribed medicines, common medicine categories, and polypharmacy (use of multiple medicines).
• Participation rates were 76% in 2004 and 73% in 2008.

Main Results:

• Overall prevalence of using one or more prescribed medicines remained stable (46.8% vs 47.3%).
• Significant reductions in medicine use were observed in younger adults (15-24 years) and older adults (≥65 years).
• A significant increase in medicine use was noted in the 35-44 years age group, while respiratory and musculoskeletal medicine use decreased.

Conclusions:

• The study highlights varying patterns of prescribed medicine use across different adult age groups in Australia.
• Findings suggest a need to address de-prescribing, monitor for adverse events, and consider the economic impact of medication use.
• This research provides insights into the quality use of medicines within the Australian population.
