TL;DR: Instrumental variable analysis may be a useful technique in comparative effectiveness studies of cancer treatments if an acceptable instrument can be identified and differed from the traditional multivariable and propensity score results but were consistent with findings from the subset of elderly patient with early-stage disease in the trial.

TL;DR: If all uninsured people were fully covered, their medical spending would increase by $122.6 billion and the cost of a specific plan nor necessarily the same as the government's costs, which could be higher, depending on plans' financing structures and the extent of crowd-out.

TL;DR: Beneficiaries whose usual physician was a medical specialist or reported inadequate office visit time, medical specialist supply, provider for-profit status, care fragmentation, and Medicare fees were associated with higher costs.

TL;DR: Results show that Medicare fees are positively related to quantity provided for all eight services, and are significantly different from zero and elastic for five of them, consistent with the general economic proposition that supply curves for medical services are positively sloped.

TL;DR: Two key casemix adjustment methods—controlling for patient conditions obtained from diagnoses on claims and expenditures of those at the end of life—were evaluated and it was found that the assumption underpinning the latter approach—that persons close to death are equally sick across areas—cannot be supported.
