Background Increasing patient contributions and reducing the population exempt from pharmaceutical co-payment and co-insurance rates were one of the most common measures in the reforms adopted in Europe during 2010-2015.
Objective We estimated the association between the introduction of a capped co-payment of (sic)1 per prescription and drug consumption of the publicly insured population of Catalonia (Spain).
Methods We used administrative data on monthly pharmaceutical consumption (defined daily doses [DDDs]) from January 2012 to December 2014, for a representative sample of 85,000 people.
Results Our results showed that consumption increased in the 2 months previous to the introduction of the measure, and fell with the introduction of the 'Euro per prescription' co-payment. The average net response associated with the reform (including anticipation) was a reduction of 4.1 DDDs per person per month, representing a 6.4% reduction. The decrease in pharmaceutical consumption was larger for those individuals who had free medicines prior to the reform compared with those who already paid a co-insurance rate (9.7 vs. 1.4 DDDs per person per month). The largest reduction in DDDs per person occurred in the following groups: dermatologic drugs, antihypertensives, non-insulin antidiabetic drugs, insulin antidiabetic drugs, and laxatives.
Conclusion A uniform capped low co-payment may give rise to a major reduction in drug consumption to a much greater extent among those who previously had free prescriptions.
