Our model could explain a significant portion of the variance in cost with an R of 0.62.> -wrap-foot> * = Numbers represent percent change in cost for 1% change in the exposure variable (length of stay, number of procedures).
For each alternative the mean costs, mean effectiveness, differential variance in costs, differential variance in effects and covariance between the differences in costs and effects, and the INB were estimated, setting an efficiency threshold (k = 30,000 monetary units per QALY gained).
ED treatments are patient specific and the variance in cost of each case is fairly high and difficult to predict.
It is, however, important to note that the regression explains only a small proportion of the overall variance in cost per LY/QALY/DALY group.
For adults with prescriptions, the variance of cost explained by ACGs was 35.4%, by physician-center was 1.8% and age 10.5% (residual 52.3%).
Among the strengths of the study are the complete billing data of participating physicians, and, in contrast to other research [ 27], a considerable amount of variance in cost outcomes could be explained by statistical models used in the study.
The greatest variance in cost-benefit ratio was displayed in the cost assigned to an ADE.
Because the modelled patient pathways were the same for each diagnostic technology, only variance in costs between the technologies themselves contributed to overall cost differences, but these were trivial in comparison to the overall burden posed by DPN.
Given that our regression equation explains 21% of costs, further studies could be done to determine whether other variables might account for additional variance in costs.
