Hence, studies that report favourable results are overrepresented and there is a tendency to overestimate efficiency and effectiveness of health care interventions.
Given the tendency of DEA to overestimate efficiency when the number of factors considered is relatively high, the number of outputs was limited to five with a balance of maternal, child, and general health services (24).
The results here found reveal how previous studies clearly overestimated the efficiency of these devices.
However, a comparison of these data with predictions from an earlier mathematical model showed that, for R increasing above about 2, the predictive model significantly overestimated aspiration efficiency in relation to what was measured in these new experiments.
However, the fact that HLC was undertaken outdoors while CDC LT was conducted indoors could have overestimated the efficiency of HLC compared with CDC LT.
These results then suggest that the common assumption of a constant mortality hazard has led most vector-borne disease models to overestimate the efficiency of mosquito control.
It was shown that the reactor model with the assumption of non-wetted pores overestimated the absorption efficiency, and a wetted pore length between 6.25 9.75% would yield a very good agreement with the experimental data.
Despite these structural and functional weaknesses of the Austrian health-care system, self-reported patient satisfaction is high; therefore, patient satisfaction should not be overestimated in assessing the efficiency of a health-care system.
"Business decision makers tend to overestimate the energy efficiency of their buildings," said Lee Ann Head, vice president of research and insight at the Shelton Group, which conducts research on energy markets.
Uncertainties in BMP effectiveness over time may result in overestimating long-term efficiency in watershed planning strategies.
