まとめ
ISO 20776-2規格では,抗菌感受性検査 (AST) デバイスの検証において,カテゴリ的合意 (CA) よりも本質的合意 (EA) とバイアスを優先しています. これは,外部品質評価 (EQA) と抗菌管理 (AMS) フレームワークに影響を及ぼします.
科学分野:
- クリニカル・マイクロバイオロジー
- 医療機器の検証について
- 抗生物質耐性菌は,抗生物質耐性菌として存在します.
背景:
- ISO 20776-2:2021 規格は,抗菌感受性検査 (AST) デバイスの検証のための断定的な合意 (CA) を強調し,本質的な合意 (EA) とバイアスを好む.
- CAが進化する臨床ブレイクポイントに依存しているため,外部品質評価 (EQA) の縦断的な比較が難しくなっています.
研究 の 目的:
- EQAプログラムに対する更新されたISO規格の影響を議論する.
- ASTデバイス検証の主要な指標としてEA/biasを提案する.
- 抗微生物管理 (AMS) に関するEUCASTとCLSICAの枠組みを比較する.
主な方法:
- EUCASTとCLSIのCAフレームワークの比較分析.
- EQAスコアリングに対するブレイクポイントの変化の影響の評価.
- インドの熟練度スキームにおけるEQAのためのハイブリッドアプローチの議論.
主要な成果:
- EA/biasへの移行は,ブレイクポイントの変化によるCAの制限に対応しています.
- EUCASTの"I"カテゴリーは曖昧さを軽減するが,不一致を増加させる可能性がある;CLSIの"I"はエラーに対応するが,オーバーコールのリスクがある.
- ハイブリッドのEQAアプローチは,インドのCLSIベースのスキームに提案されています.
結論:
- 外部品質評価 (EQA) は,新しいISO規格に適応し,EA/bias.を優先する必要があります.
- EUCASTとCLSI間のCAフレームワークの調和は,効果的な抗微生物管理 (AMS) に不可欠です.
- 適応型のハイブリッドEQA戦略は,インドのようなCLSIガイドラインに依存する地域のために推奨されます.

01:16Critical Region, Critical Values and Significance Level
13.5K
The critical region, critical value, and significance level are interdependent concepts crucial in hypothesis testing.
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...

1.1K
Kendall's Coefficient of Concordance (W), also known as Kendall's W, is a non-parametric statistical measure used to assess the agreement or concordance between multiple raters or judges when they rank a set of items. It is often used when you have ordinal data (ranks) and you want to see if there is consistency or consensus among the raters. It is widely applied in research areas such as psychology, medicine, and social sciences, where multiple judges are asked to rank or rate subjects...

01:16Goodness-of-Fit Test
9.3K
The goodness-of-fit test is a type of hypothesis test which determines whether the data "fits" a particular distribution. For example, one may suspect that some anonymous data may fit a binomial distribution. A chi-square test (meaning the distribution for the hypothesis test is chi-square) can be used to determine if there is a fit. The null and alternative hypotheses may be written in sentences or stated as equations or inequalities. The test statistic for a goodness-of-fit test is given as...

01:29Reliability and Validity
14.2K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

01:17Soundness of Cement
608
The soundness of cement refers to the ability of cement paste to retain its volume after setting. Unsound cement can lead to expansion and structural damage due to the presence of free lime, magnesia, and calcium sulfate. Free lime hydrates very slowly, expanding and causing unsoundness, which is difficult to detect because it intercrystallizes with other compounds. Magnesia also reacts with water, forming crystals that can disrupt the cement's structure. Calcium sulfate can create...

01:04Significance Testing: Overview
12.8K
Significance testing is a set of statistical methods used to test whether a claim about a parameter is valid. In analytical chemistry, significance testing is used primarily to determine whether the difference between two values comes from determinate or random errors. The effect of a particular change in the measurement protocol, analyst, or sample itself can cause a deviation from the expected result. In the case of a suspected deviation/outlier, we need to be able to confirm mathematically...
