Health Policies on Pharmaceuticals Luke Connelly Professor of Health Economics Centre for the Business and Economics of Health E: l.connelly@uq.edu.au Overview • Policies on pharmaceuticals – in context of policies on medical technologies generally – i.e., pharmaceutical innovation is a subset of health technology innovation • Technology as the major driver of health expenditure growth • Economic evaluation as the “fourth hurdle” – Safety, efficacy, effectiveness, – cost-effectiveness Health Expenditure Growth Current Health Expenditure (%GDP), 1960-2014 18.0 16.4 16.0 14.0 12.0 Australia 10.0 8.8 8.0 6.2 Canada New Zealand United Kingdom United States 6.0 4.5 4.0 2.0 2014 2012 2010 2008 2006 2004 2002 2000 1998 1996 1994 1992 1990 1988 1986 1984 1982 1980 1978 1976 1974 1972 1970 1968 1966 1964 1962 1960 0.0 Source: OECD (2016).

New Medical Technologies? Health Expenditure Growth Due to “The Residual” (1992-03 to 2002-03) Source: Productivity Commission (2005, Table 3.2, p.53). Watch the Panel Discussion: Link to Global Leadership Series: Zweifel, Birch, Gannon, Connelly Cost-Effectiveness as the “Fourth Hurdle” The First Hurdle: Safety • Is the technology (pharmaceutical/procedure) safe? The Second Hurdle: Efficacy • Does the technology (e.g., pharmaceutical/procedure) have the capacity to produce the desired effect? Effectiveness • Does the technology (e.g., pharmaceutical/procedure) actually produce the desired effect, in practice? – This question is usually answered via randomised controlled trials (RCTs) – Note that a residual question is whether or not the technology works when administered under non-trial conditions. • e.g., are there any aspects of behaviour of patients/practitioners under “normal” conditions that modify effect? Cost-Effectiveness • Is the technology cost-effective? – The broader question is whether or not its benefits outweigh its (opportunity) costs – Cost-benefit analysis (CBA) is rarely performed, though. – Typically, cost-effectiveness analysis or cost-minimisation analysis is performed • Superior? • Non-Inferior? Pharmaceutical Policy in Australia (PBS) • Pharmaceutical Benefits Scheme (PBS http://www.pbs.gov.au/ ) is a central part of the Australian Medicare system – Introduced in 1984 – Subsidises a large number of prescription medicines • Not all medicines (including prescription medicines) are “on” PBS. Subsidies versus Approval to Market • Not all drugs that are approved for sale receive a subsidy. • The Therapeutic Goods Administration (TGA) is the regulatory authority that determines whether or not products with a therapeutic claim may be sold on the Australian market – https://www.tga.gov.au/about-tga • TGA approval to market does not imply public subsidies for therapeutic products. TGA • The Therapeutic Goods Administration (TGA) in Australia regulates the sale/marketing of all goods for which a therapeutic claim is made: “including prescription medicines, vaccines, sunscreens, vitamins and minerals, medical devices, blood and blood products” • Even cough lozenges… • See https://www.tga.gov.au/tga-basics Pharmaceutical Benefits Advisory Committee • Australia first country to introduce mandatory economic evaluations of all new proposals to list pharmaceuticals on the PBS for subsidy – In 1993 • PBAC is the statutory authority that makes decisions on whether or not to list a drug for public subsidy. PBAC • Submissions to the PBAC follow a clearly defined process. • PBAC has two sub-committees – Economics Sub-Committee – Drug Utilisation Sub-Committee • http://www.pbs.gov.au/info/industry/listing/participants/pba c • The PBAC decisions are published (see above).

Selected Indicators • Australia’s Pharmaceutical Benefits Advisory Committee (PBAC) – recommends drug submissions for listing at a considerably lower rate (49.6%) than its UK counterpart (87.4%) (Clement et al. 2009) Selected Indicators Selected Indicators Source: George, Harris and Mitchell (2001, p.1103). Lamda • The cost-effectiveness threshold (or ICER threshold) is sometimes denoted ƛ • What are the implications of setting lambda at a particular level? • Let’s say it’s $76,000, for argument’s sake… Goldilocks Pricing • See Varian (1997) in Shapiro and Varian (1999) – Goldilocks pricing and versioning for information goods. • My version, applied to pharmaceuticals (which are also “information products”) does not require “versioning”, just pricing. Profit-Maximising IP Owners: • Take lamda…(=$76,000) • Take the denominator of the ICER (ΔQALYs) – Let’s suppose the manufacturer’s intervention produces 10 QALYs, on average, and it has good evidence. • Then, just solve for price. • $76,000/10=$7,600 per intervention. Class Exercise: Third-Degree Price Discrimination Class Exercise • Break into teams of 3-4. • Task – You have been retained as consultants to help a pharmaceutical company devise a profit-maximising strategy to launch its patentprotected drug in three target markets. – The target markets have different propensities to pay. – Advise the company how and when to launch its drug in each of these markets. – Explain the strategy, conceptually, using economic tools. Third-Degree Price-Discriminators: • How does this price look? • If you can segment the market, don’t launch here if it establishes a lower price for your product than you may get elsewhere. • Launch decision (timing?, launch at all?) depends on your other markets (inter alia). But, Consumers and IP Owners: • IP owners may be able to strike a deal with the monopsony buyer (Australian Government) for confidential pricing arrangements: – the price listed on the PBS may not be what the government actually pays; and – risk-sharing arrangements may also be available. Advantages • Lower prices and quicker access for Australian consumers • Lower opportunity costs of launching early in Australia – turns early launches into profit-maximising strategies ceteris paribus. Evidence on Drug Launches and Delays • Danzon, Wang and Wang (2005) – study drug launches across 25 OECD countries 1994-1998 – of 85 new chemical entities (NCEs) launched only 55% of the potential launches actually occurred. – US: 73 launches – Australia: 43 launches – New Zealand 13 launches Does Australia Have it “About Right”? • Actually…we don’t know. Allocative Efficiency In Other Sectors: • The “Value of a Statistical Life” is used to make public policy. • See Abelson (2007). • For an extensive treatment see Connelly (2013, link) and the other submissions to Victorian Parliament. What is Current VSL? • Abelson (2007) provides a good overview of the issues and ultimately recommends Australia adopt a value of a statistical life (VSL) of $3m-$4m for a “healthy prime age individual” (p.19) – assuming 40 years of life lost: $151,000 per lifeyear saved (approx. $176,250 (AUD2013)). What is Current VSL? • Aldy and Viscusi (2007, p.9) “The most plausible labor market estimates involve VSLY values in the $300,000 [USD] range”. • Or, more recently, about $10m (US) for a “primeaged individual”. Problem? • The adoption of a different threshold values as decision rules across sectors is a source of potential inefficiency – e.g., if a threshold of $75,000 per LY were applied to “health sector” investments; and a $225,000 threshold were applied to road safety investments… Problem? – some investments that pass the threshold test in the latter would fail the threshold test in the former; and – the social return to public investments would not be maximised. • Also see Birch and Gafni (2006) on the “Silence of the Lambda”. For Discussion (Class Exercises) • Temporal distribution problems – Discounting – Health promotion/prevention • Alternative purchasing models – Patent “buy-outs”? – See Kremer 1988 For Discussion (Class Exercises) • Use of stated preferences – In health economics • For utilities • For willingness-to-pay (QALY) • Challenges arising – New technologies in, e.g., genetic testing Other Matters • Level playing field? – New technologies – Extant listings – On- and off-schedule interventions • Private health insurance • Consumer choice and literacy Selected References and Other Sources AIHW (2014), Australia’s Health 2014, AIHW: Canberra.
