1. The production of the desired effects or results with minimum waste of time, money, effort, or skill.
2. A measure of effectiveness; specifically, the useful work output divided by the energy input.

efficiency

Lab medicine The relative ability of a test to detect a disease, while maintaining the rate of false positive results to a minimum; the efficiency of a test is defined as the number of true positives and true negatives multiplied by one hundred, divided by the sum of true positives, true negatives, false positives and false negatives.

Patient discussion about efficiency

Q. Is electric shock efficient for ocd? Is it dangerous? My husband has OCD for 15 years now. He was also diagnosed with mania-depressia. He takes so many medications and nothing really helps. We were offered to try electric shock and I'm scared. Is it dangerous? What are the chances of this method to work for him?

A. Electroconvulsive therapy (ECT) is indeed considered effective for OCD, although it's not the first line of treatment. It does have its risks, including memory loss, disorientation and sort of confusion. There is also a change in the activity of the heart but it's rarely significant.

Generally it can be said that it's not an absolutely safe treatment, but it may help, especially if other drugs don't help.

More recently, critics of energy efficiency programs have argued that in order to produce sufficient evidence of the programs' benefits, a true randomized experiment (where subjects are randomly assigned to treatment and control conditions) must be conducted.
I A particularly objectionable criticism of energy efficiency programs that has rarely but occasionally been raised is that evaluations that show utility energy efficiency programs are cost-beneficial must somehow be biased.
In this study, the assumption of VRS was employed for analysis due to the consideration that the data points are enveloped by this approach more tightly, as a result scores of technical efficiency estimated would be higher than those gained under CRS.
