Incremental net benefit in randomized clinical trials.
There are three approaches to health economic evaluation for comparing two therapies. These are (i) cost minimization, in which one assumes or observes no difference in effectiveness, (ii) incremental cost-effectiveness, and (iii) incremental net benefit. The latter can be expressed either in units of effectiveness or costs. When analysing data from a clinical trial, expressing incremental net ...
متن کاملCost-Optimal and Net-Benefit Planning - A Parameterised Complexity View
Cost-optimal planning (COP) uses action costs and asks for a minimum-cost plan. It is sometimes assumed that there is no harm in using actions with zero cost or rational cost. Classical complexity analysis does not contradict this assumption; planning is PSPACE-complete regardless of whether action costs are positive or non-negative, integer or rational. We thus apply parameterised complexity a...

متن کاملThe Social Security Early Retirement Benefit as Safety Net
As the baby boom generation begins to retire and fiscal pressures from entitlement programs become more acute, evidence of improving health and increasing life expectancy in these cohorts has led many to suggest taking advantage of improved work capacity among older adults by increasing age requirements for the Social Security and Medicare programs. Currently, however, more than half of workers...
متن کاملNet Clinical Benefit of Warfarin in Patients With Atrial Fibrillation
Background—Known risk factors for bleeding during anticoagulant treatment are largely the same as those predicting thromboembolic events in patients with atrial fibrillation (AF). Our objective was to investigate how to maximize the likelihood of avoiding both stroke and bleeding. Methods and Results—All 182 678 subjects with atrial fibrillation in the Swedish Hospital Discharge Register were s...
