“…Maes et al propose two possible solutions to comply with the ESA: the payer pays for the service of the treatment delivering long-term health outcomes or the payer pays for data services as a delivered data package per year instead of paying for a single treatment administration ( Maes et al, 2019 ). Furthermore, healthcare systems wishing to implement spread payments may face national legal barriers which may require adjustment of country-specific regulations ( Carlson et al, 2009 ; Carlson et al, 2011 ; Espin et al, 2011 ; Ferrario and Kanavos, 2013 ; Tuna et al, 2014 ; Kleinke and McGee, 2015 ; Barlas, 2016b ; Proach et al, 2016 ; Montazerhodjat et al, 2016 ; Kanavos et al, 2017 ; Nazareth et al, 2017 ; NEHI, 2017 ; PWC Health Research Institute, 2017 ; Spark et al, 2017 ; Goncalves et al, 2018 ; Salzman et al, 2018 ; Infante et al, 2019 ; Lorente et al, 2019 ; Mahendraratnam et al, 2019 ). For instance, the current legislation in Spain only allows long-term spending for certain investments which excludes medicines and Sweden does not allow payments for more than three years for non-investment consumables (that are not purchased to deliver financial return) ( Alliance for Regenerative Medicine, 2019 ).…”
