Objectives. To determine changes in out-of-pocket expenditure on prescription medicines for Australian patients, and how patient expenditure compares with other Organisation for Economic Co-operation and Development (OECD) countries. Methods. We examined out-of-pocket expenditure on prescription medicines by patients in Australia between 1970 and 2007, and between Australia and 15 other OECD countries (Canada, Czech Republic, Denmark, Finland, France, Germany, Japan, Republic of Korea (South Korea), Luxembourg, Poland, Slovak Republic, Spain, Sweden, Switzerland and the United States) in 2005. Findings. Spending on publicly subsidised medicines by Australian patients increased from $16 per person in 1971 to $62 in 2007. Patient expenditure on all prescription medicines had risen to $134 per person in 2007. Out-of-pocket expenditure for Australian patients ranked 4th of 14 OCED countries with universal pharmaceutical subsidies. Australian patients pay 28% of national pharmaceutical expenditure; more than patients in South Korea (27%), Slovak Republic (26%), Sweden (22%), France, Luxembourg, Japan and Switzerland (17%), Germany (15%), Czech Republic (11%) and Spain (6%), but less than patients in Finland (36%), Denmark (33%) and Poland (34%). Conclusions. Compared to other OECD countries, Australian out-of-pocket costs are now in the mid to upper range. Further increases have the potential to significantly affect access to care.

Introduction: Regulatory advisories on hydroxyzine and risk of QT prolongation and Torsade de pointes (TdP) were issued in the UK in April 2015 and Canada in June 2016. We hypothesized patients with risk factors for QT prolongation and TdP, compared with those without risk factors, would be less likely to initiate hydroxyzine in the UK and in British Columbia (BC), Canada, following advisories., Methods: We conducted a longitudinal study with repeated measures, and evaluated hydroxyzine initiation in a UK cohort and a concurrent BC control cohort (April 2013-March 2016) as well as in a BC advisory cohort (June 2014-May 2017)., Results: This study included 247,665 patients in the UK cohort, 297,147 patients in the BC control cohort, and 303,653 patients in the BC advisory cohort. Over a 12-month post-advisory period, hydroxyzine initiation decreased by 21% in the UK (rate ratio 0.79, 95% confidence interval 0.66-0.96) relative to the expected level of initiation based on the pre-advisory trend. Hydroxyzine initiation did not change in the BC control cohort or following the Canadian advisory in the BC advisory cohort. The decrease in hydroxyzine initiation in the UK in the 12 months after the advisories was not significantly different for patients with risk factors compared with those without risk factors., Conclusion: Hydroxyzine initiation decreased in the UK, but not in BC, in the 12 months following safety advisories. The decrease in hydroxyzine initiation in the UK was not significantly different for patients with versus without risk factors for QT prolongation and TdP., (© 2022. The Author(s).)
