Strongman A1 - AB - Clinicians and people with narcolepsy report varied access to higher-cost narcolepsy treatments in England associated with variations in national and local commissioning. There are no publicly available data quantifying use of these drugs to support policy decisions. We therefore aimed to describe national, regional and local prescribing trends for higher-cost narcolepsy drugs using new national databases. We used the English prescribing dataset and secondary care medicines data to quantify volumes of high-cost narcolepsy drugs issued between 01 January 2019 and 31 December 2022. Volumes were converted to World Health Organisation defined daily doses, to estimate the monthly number of defined daily doses of sodium oxybate, pitolisant and solriamfetol issued by each integrated care board and region. We compared national, integrated care board, and regional level issuance of each drug over time. Analysis of almost 6000 primary care prescriptions and 2000 cumulative months of secondary care pharmacy stock data, issued across 41/42 integrated care boards in England, revealed a 49.1% increase in issuance of high-cost narcolepsy drugs between 2019 and 2022. In 2022, sodium oxybate accounted for 52.66% of issuance, pitolisant 43.09% and solriamfetol 4.25%, with 22.31% of defined daily doses issued in primary care. Three integrated care boards (NHS Southeast London, NHS Cumbria and North-East, NHS Cheshire and Merseyside) predominate, issuing 56.33% of all defined daily doses. Variations between integrated care boards and regions differ substantially by drug and route of issuance. Our findings describe substantial variation in the use of specialist narcolepsy drugs in England, and highlight the untapped potential of using large, public domain datasets to publicly review higher-cost drug prescribing.
