AVERT

Cardiology Atorvastatin VErsus Revascularization Treatments. A trial comparing the efficacy of aggressive lowering of cholesterol in patients at risk of future cardiovascular events (ischaemic heart disease and stable angina) to percutaneous coronary intervention.
Conclusion Atorvastatin evoked a 46% reduction in LDL-C compared to an 18% reduction with revascularization; ischaemic events were 36% lower with atorvastatin than with revascularisation; the first ischaemic event occurred after a much longer time in atorvastatin patients. Aggressive LDL-C lowering in patients with stable CAD results in a markedly reduced risk of cardiovascular events (nonfatal heart attack, bypass surgery, revascularization, and worsening angina) compared with patients receiving angioplasty followed by usual care. In AVERT, 13% of patients treated with atorvastatin suffered a cardiovascular event compared with 21% of patients receiving angioplasty and usual care.
Cardiovascular surgery Artificial Valve Endocarditis Reduction Trial. A trial comparing the St. Jude masters series valve with silver (Silzone) coated sewing cuff with the St Judes mechanical heart valve with uncoated cuff
Logistics Randomised, multicenter.
Conclusion Trial was stopped in 2000, when 807 patients had been randomised, because of an increased risk of major paravalvular leak leading to valve explant in the Silzone arm of the study.

Bartik (1988) demonstrated the relationship between averting costs savings and willingness to pay for an individual under certain assumptions.
Results in this paper indicate that the mean of one measure of averting costs was not less than estimated willingness to pay.
This lack of correlation, and the indeterminacy of any correlation on theoretical grounds, limits the usefulness of the valid averting cost measure of benefits in policy analysis.
Their models indicated the need for empirical results to test assumptions of cleanliness and averting expenditure behavior.
Bartik (1988) also stated that theoretically correct measures of WTP could be estimated using averting expenditures if information was obtainable concerning the household's production technology.
Roach (1990) demonstrated that including household time as an input into the production function for personal environmental quality did not change Bartik's (1988) conclusions about the ability of averting expenditure estimates to bound willingness to pay.

Section 3 discusses the theoretical framework of both contingent valuation method and averting behaviour approach.
1998) describe the averting behaviour approach to the valuation of drinking water quality.
Existing studies have considered either insurance or averting activities separately and typically employ a single-preference evaluation technique.
The mail survey elicited hypothetical, open-ended annual household willingness to pay (WTP) values simultaneously for special wildfire insurance, private averting activities (e.
In both settings, the authors examine (1) the factors that influence demand for insurance and averting activities, (2) WTP for risk reduction options, (3) the distribution of expenditures between insurance and averting activities, and (4) the effects of providing wildfire risk zone map information.
