Cost-effectiveness analysis based on the number-need-to-treat:common sense or non-sense?

we argue that NNT may be a straightforward measure of benefit when the effect of an intervention is immediate,but that serious problem arise when the effect is delay rather than avoidance of an adverse event

A simple alternative is to estimate the cost per adverse event avoided

Cost-effectiveness analysis based on the number-need-to-treat:common sense or non-sense?

譯:成本有效之分析以多少病人必須作治療為基礎:有共同認識或無知(胡說)

we argue that NNT may be a straightforward measure of benefit when the effect of an intervention is immediate,but that serious problem arise when the effect is delay rather than avoidance of an adverse event

譯:我們爭論的是NNT(多少病人需要治療)與其在(醫療)介入之效應是立即時,寧可是一種明確肯定的有益評估工具,但是當效應延遲導致嚴重問題產生時,也不願避免一不利事情之發生

A simple alternative is to estimate the cost per adverse event avoided

by means of the number-needed-to-treat(NNT)-'the poor man's cost-effectiveness analysis

譯:一簡單(二擇一)選擇是藉由多少病人必須治療(NTT)的方法去估算每一不利事件避開之成本---窮人的成本有效分析

註:rather than 與其...而不願,不要

註:Number Needed to Treat (NNT)

Definition

The NNT is the number of patients who need to be treated in order to prevent one additional bad outcome. It is the inverse of the Absolute Risk Reduction (ARR).NTT是多少數目的病人必須接受治療以避免另一不良結果反應.NTT是絕對風險降低之倒數

How to Calculate NNTs

NNT = 1/ARR

ARR = |CER - EER|

where

CER = control group event rate

EER = experimental group event rate

The number needed to treat (NNT) is an epidemiological measure used in assessing the effectiveness of a health-care intervention, typically a treatment with medication. The NNT is the number of patients who need to be treated in order to prevent one additional bad outcome (i.e. to reduce the expected number of cases of a defined endpoint by one). It is defined as the inverse of the absolute risk reduction. It was described in 1988.[1]
