Long term sustainability of SSN pharmaceutical coverage in Italy A twenty year outlook (2005-2025)

Key determinants of demand for pharma in public healthcare systems* • Ageing • Increase Rx volume • Price • Generic substitution • Shift to more expensive alternatives • Shift in demand • Morbidity • Mortality • Chronic illness rate • Physicians’ prescribing behaviour • Disposable income • Education • Access to healthcare Source: OSMED data 2007 * Majeed A, Malcom I (1999)
Study objective • To determine the long term impact of age and generic substitution on the Italian public pharmaceutical spending. • Key assumptions: • Base year: 2005 • Fundamental level of SSN pharmaceutical coverage unchanged • No drastic shifts in pharmaceutical demand • All other determinants unchanged • Generics price = 40% of branded off-patent
ASSET outcomes • Patient and cost data were obtained directly from computerised prescription records for a two year period, from January 2004 to December 2005. • The ASSET sample totalled 3,175,691 residents. • The ASSET mean costs were applied to the Istat projections of the Italian population (intermediate scenario) * Favato G, Mariani P, Mills RW, Capone A, Pelagatti M, et al (2007) ASSET
Impact of ageing on demand:+24% over twenty years (2005-2025) 124 100
Goodness of fit Polynomial regression model: y = -0.0055x2 + 1.2906x + 98.759 R2 = 0.9999
Quantifying the impact of generics • Population: ISTAT projections 2005-2025 (intermediate scenario) at year end. • Impact of generic substitution: 40% price reduction, calculated at year end for each molecule going off patent on its average cost by age group (source: ASSET) • The calculated reduction is then carried forward to the following year.

Goodness of fit Polynomial regression model: y = 0.0846 x2 – 1.6324x + 100.19 R2 = 0.8854

Net effect of generic substitution:2001-2004 equilibrium • ATC4 class growing: • 32.6% of drugs off-patent UP leaders • 18.6% of drugs off-patent DOWN shift • ATC4 class declining • 13.9% of drugs off-patent UP low impact • 34.5% of drugs off-patent DOWN shift sustainable cost reduction potential cost increase (therapy shift)
Conclusions • Ageing and price are key determinants of pharmaceutical demand in a state funded, open access social healthcare system like the Italian SSN. • All else equal, by 2025 the expected ageing of the Italian population would increase the cost of the current public pharmaceutical coverage by 24%. • Generic substitution could offset the upward trend driven by ageing. • Cholesterol inhibitors and anti hypertensive agents could reduce the total cost of cardiovascular treatments by 25% . • Due to time to patent expiration, the next couple of years would provide critical indications about the sustainability of the current pharmaceutical coverage provided by the SSN in Fascia A.
CHANGE Shift in pharmaceutical demand Accelerated shift to more expensive treatment options Physicians behaviour Patients behaviour POLICY IMPLICATIONS Redefine levels of SSN coverage Outcome based prescribing guidelines Rationale prescribing Reduce moral hazard: Link reimbursement to compliance Education: health as capital All else equal… a major limitationof the age/generic substitution model
