Economic evaluation - methodology • Simplistic model – apply cost constraints on “expensive” drugs • Fails because some treatments that are initially expensive are highly effective and save money elsewhere in the health system • e.g. by increasing cures • or by saving money from other healthcare budgets • Fails because “cheap” high volume drugs may be relatively ineffective
Economics for the uninitiated – the key pints in 5 minutes! Economics is not primarily about saving money It is about using scarce resources as efficiently as possible Economists never say “cheap”or “expensive” - they say “cost-effective” or “not cost effective” You know more economics than you think
You know more economics than you think Economics or Οἰκονομία – is a Greek word Oikos = “the household” + Nomos = “wise rules” Economics - “wise rules for managing the household” “Health economics” = Wise rules for managing the hospital
The 3 “E”s of pharmaco-economics: efficacy, effectiveness, efficiency
Is it worth doing compared to other things we could do with the same money? A Pound can only be spent once Once money has been spent on one thing – it is a lost “opportunity” to spend it on something else economists call this the “opportunity cost” of spending
The power of health economic thinking • Assuming we worry about costs, and that some public funded health care is essential: could we perform better? • 185 publicly-funded interventions in the United States cost about $21.4 billion per year, for an estimated saving of 592 000 years of life (considering only premature deaths prevented). • Re-allocating those funds to the most cost-effective interventions could save an additional 638 000 life years if all potential beneficiaries were reached. • Tengs TO. Dying too soon: how cost-effectiveness analysis can save lives. Irvine, California, University of California, National Center for Policy Analysis, 1997 (Policy Report No. 204)
“Cheap” and “expensive” are not terms used in economic assessments • Which is the most cost-effective option? We make economic decisions all the time – but some are very well informed – buying a car for example
“Cheap” and “expensive” are not terms used in economic assessments • Which is the most cost-effective option?
The rise in cost/QALY studies over time We make economic decisions all the time – in medicine the metric is the increasingly popular cost-QALY study
‘Cost–effectiveness’ • To understand ‘cost-effectiveness’, we need to know: A single metric of risks/benefits to length and Quality of life A single metric of costs QALY € £ $ • Costs • The costs of treating • The costs of not treating • The costs of alternatetreatments • Effect • Benefits seen • Magnitude of those benefits • Duration of those benefits • Side-effects seen • Magnitude of those side-effects • Duration of those side-effects
Economists use the cost-QALY model to assess the benefits of treatment • Quality of life and length of life is described by the Quality Adjusted Life Year “QALY” • Quality Adjusted Life Year • One year lived at full quality scores = 1x1 = 1 QALY • Two years lived at 70% QOL scores = 2 x 0.7= 1.4 QALY • Six months lived at 50% QOL scores =0.5 x 0.5 = 0.25 QALY Time (in years) x % of full Quality of Life = QALY Question: 3 years at 50% of full QOL = ? Answer: 3 x 0.5 = 1.5 QALYs
Economists use the cost-QALY model to assess the benefits of treatment • Quality of life and length of life is described by the Quality Adjusted Life Year “QALY” Question 2: If this treatment costs 15,000 Euros the cost/QALY would be? Answer: 1.5 QALYs/15,000 = 10,000 Euros/QALY Question: 3 years at 50% of full QOL = ? Answer: 3 x 0.5 = 1.5 QALYs

Published reimbursement limits Aim is to reimburse in proportion to the medical value of a treatment More effective treatments are considered more valuable They gain a higher “QALY” score

Evidence based treatment Best clinical outcome Includes economic evidence from cost-effectiveness studies Cost constraints in cancer treatment:What can we do as individuals?
Focus care to where it helps us live longer and live better “Estimates suggest that as much as $700 billion a year in health care costs do not improve health outcomes. They occur because we pay for more care rather than better care” • Peter Orszag, director of the White House Office of Management and Budget, May 2009 interview with NPR. • http://www.factsforhealthcare.com/whitepaper/HealthcareWaste.pdf

Response to cost constraints in cancer treatment: 1 - Clinical guidelines save money • In a landmark study, eight practices in the US Oncology network introduced a single guideline for non-small cell lung cancer treatment. • Overall, outpatient costs were 35% lower for patients on clinical pathways, with an average 12-month cost of $18,042 for pathway versus $27,737 for individualised non-pathway treatment. • Survival was unaltered by cost control • Savings were realised from both reduced primary drug costs and also from a 23% reduction in the use of supportive care medicines by advocating less toxic regimens. • Neubauer MA, Hoverman JR, Kolodziej M, et al: Cost effectiveness of evidence-based treatment guidelines for the treatment of non–small-cell lung cancer in the community setting.

Response to cost constraints in cancer treatment: 1 - Dose banding • Dose banding offers a further chance to minimise drug waste, reduce pharmacist time and maximise cost avoidance. • In a 3-month study, one pharmacy department processed 126 prescriptions for biologic anticancer agents. • Dose banding could reduce drug wastage for 42% of these orders. • Potential cost savings from dose banding in one clinic was estimated at $24,434 for a 3-month interval evaluated Winger BJ, Cost savings from dose rounding of biologic anticancer agents in adults. Oncol Pharm Pract. 2011 Sep;17(3):246-51.
Response to cost constraints in cancer treatment: 1 - Test dosing • Test dosing may save waste if reactions occur. • Expensive biologic medications may have significant reactions. After this, the unused infusion is discarded. • These tend to occur most frequently on the earlier cycles of treatment. • A study from Boston Medical Center, USA, showed that by giving a test dose of rituximab before starting the infusion saved about $2,000 per patient in costs Melton C.
