Abstract

Objectives: To determine the use and expenditure associated with cystic fibrosis (CF) modulator therapies in Ireland since their reimbursement in 2013.

Design: A retrospective analysis of a national drug claims database.

Setting: The data included in this study are nationally representative (Ireland).

Participants: Data on all persons receiving CF modulator therapies were included.

Methods: We obtained national claims data for CF therapies from the Health Service Executive's Primary Care Reimbursement Service. We determined the use and expenditure associated with CF therapies from January 2012 to March 2020.

Results: The increased prescribing of CF modulator therapies was associated with an approximate fivefold increase in expenditure from €23 million in 2013 to €113 million in 2019. Many patients who initiated lumacaftor/ivacaftor in 2017 went on to receive symptomatic therapies, and subsequently initiated tezacaftor/ivacaftor in 2019.

Conclusion: Despite none of these modulator therapies demonstrating value for money when subjected to health technology assessment, the associated Irish expenditure reached €113 million in 2019 alone.

Keywords: cystic fibrosis; health economics; rationing.
