Function
Economic-burden estimation function
Maps attributable resource use, losses, population counts and valuation assumptions to the economic burden of a disease, injury or risk factor.

Implementations
Excel
Calculate total economic burden
Excel sums the included mutually exclusive burden categories.
=SUM(IncludedBurdenCategories)
Assumptions
Mutually exclusive categories
Included cost categories do not overlap or count the same resource loss or consequence more than once.
Common valuation basis
All categories use a compatible currency, price year, population, perspective and costing period.
Worked examples
Annual societal burden
Direct medical costs are £60 million, direct non-medical costs £4 million, informal care £16 million and productivity losses £30 million. Total annual burden is £110 million.
K = 4; B_k = [60000000,4000000,16000000,30000000]; B_total = 110000000
Common errors
Treating economic burden as recoverable savings
The total burden is a valuation of associated resources and losses and does not show how much cash an intervention could release.
