In the pharmaceutical industry, a critical aspect of maintaining high testing standards involves understanding and managing Out-of-specification (OOS), Out-of-trend (OOT), and Out-of-expectation (OOE) results that may arise during quality control testing. Our post aims to clarify these concepts, explore their differences, and discuss their role in contemporary pharmaceutical testing practices.
在制藥行業(yè)中，保持高測試標準的一個關(guān)鍵方面是理解和管理質(zhì)量控制測試期間可能出現(xiàn)的不符合規(guī)格（OOS）、不符趨勢（OOT）以及超出預期（OOE）的結(jié)果。我們的文章旨在澄清這些概念，探討它們之間的區(qū)別，并討論它們在現(xiàn)代制藥檢測實踐中的作用。
Out of Specification (OOS) Results
超出規(guī)格（OOS）結(jié)果
OOS results refer to test results that fall outside the established specifications or acceptance criteria that are present in drug applications, drug master files (DMFs), official compendia or set by the manufacturer. Specifications are typically predefined based on regulatory requirements and scientific rationale.
OOS 結(jié)果是指藥物申請、藥物主文件（DMF）、官方藥典中或制造商設(shè)定的既定規(guī)格或驗收標準之外的測試結(jié)果。標準通常是根據(jù)監(jiān)管要求和科學原理預定義的。
OOS results are immediately alarming as they directly indicate a potential quality issue with the product. They require a thorough investigation to determine the root cause, which could range from sample mishandling and analytical errors to actual product defects.
OOS 結(jié)果立即令人震驚，因為它們直接表明產(chǎn)品存在潛在的質(zhì)量問題。它們需要徹底調(diào)查以確定根本原因，范圍從樣品處理不當和分析錯誤到實際產(chǎn)品缺陷。
A meaningful multiphase investigation into OOS findings must be conducted using a comprehensive, prompt, impartial,well-documented, and scientifically sound approach. This early assessment enables the investigation of potential errors that affect product safety and quality, regulatory compliance, operational efficiency, and cost management.
必須采用全面、及時、公正、有據(jù)可查且科學合理的方法對OOS結(jié)果進行有意義的多階段調(diào)查。這種早期評估有助于調(diào)查影響產(chǎn)品安全和質(zhì)量、法規(guī)遵從性、運營效率和成本管理的潛在錯誤。
To prevent recurrence and ensure product quality, appropriatecorrective and preventive actions (CAPA) shall be taken based on the investigation outcome, which might include process adjustments, equipment maintenance, retesting, or other measures to address the identified root cause.
為防止再次發(fā)生并確保產(chǎn)品質(zhì)量，應(yīng)根據(jù)調(diào)查結(jié)果采取適當?shù)募m正和預防措施 （CAPA），其中可能包括流程調(diào)整、設(shè)備維護、重新測試或其他措施，以解決已確定的根本原因。
OOS Key Aspects:OOS 關(guān)鍵方面：
Results fail to comply with product specification
結(jié)果不符合產(chǎn)品規(guī)格
Call for immediate action (investigation) whenever OOS result is obtained
每當獲得OOS結(jié)果時，都呼吁立即采取行動（調(diào)查）
Thorough OOS investigation is covered in phases
分階段進行徹底的OOS調(diào)查
CAPA is essential to prevent the recurrence of OOS results
CAPA對于防止OOS結(jié)果再次發(fā)生至關(guān)重要
Out of Trend (OOT) Results
超出趨勢（OOT）結(jié)果
OOT results, while falling within the product’s specification limits, show an unexpected trend that could indicate a potential problem if not addressed. These results are particularly significant as they can serve as early warning signs of underlying issues in the manufacturing or testing processes. It is of utmost importance to promptly investigate and address these anomalies to preemptively identify these statistically important deviations before they escalate into critical problems.
OOT結(jié)果雖然在產(chǎn)品的規(guī)格限制范圍內(nèi)，但顯示出一種意外趨勢，如果不加以解決，可能表明存在潛在問題。這些結(jié)果特別重要，因為它們可以作為制造或測試過程中潛在問題的早期預警信號。最重要的是及時調(diào)查和解決這些異常情況，以便在這些偏差升級為關(guān)鍵問題之前先發(fā)制人地識別這些具有統(tǒng)計重要性的偏差。
Recognizing these deviations often leads to proactive measures, such as increased surveillance or preliminary investigations, aimed at preventing future instances of Out-of-Specification (OOS) outcomes.
識別這些偏差通常會導致采取主動措施，例如加強監(jiān)測或初步調(diào)查，以防止未來出現(xiàn)不合格（OOS）結(jié)果。
A critical component in managing OOT results is the analysis of trends, which plays a significant role in the ongoing enhancement of both manufacturing processes and the quality of the final product. This approach ensures a dynamic and continuous improvement framework essential for maintaining high-quality standards in the pharmaceutical sector.
管理OOT結(jié)果的一個關(guān)鍵組成部分是趨勢分析，它在持續(xù)改進制造流程和最終產(chǎn)品質(zhì)量方面發(fā)揮著重要作用。這種方法確保了一個動態(tài)和持續(xù)改進的框架，這對于保持制藥行業(yè)的高質(zhì)量標準至關(guān)重要。
OOT Key Aspects:OOT 關(guān)鍵方面：
Results are within specification but deviate from the expected pattern or historical data.
結(jié)果符合規(guī)格，但與預期模式或歷史數(shù)據(jù)存在偏差。
Can be early indicators of a process or product stability issue.
可能是工藝或產(chǎn)品穩(wěn)定性問題的早期指標。
Often leads to proactive measures, such as increased monitoring or preemptive investigation, to prevent future OOS results.
通常會導致采取主動措施，例如加強監(jiān)控或先發(fā)制人地調(diào)查，以防止未來的OOS結(jié)果。
Trend analysis is crucial in the continuous improvement of processes and product quality over time.
趨勢分析對于流程和產(chǎn)品質(zhì)量的持續(xù)改進至關(guān)重要。
Out of Expectation (OOE) Results
超出預期（OOE）結(jié)果
Out of Expectation results, also known as atypical /aberrant /anomalous /unexpected results, refer to test outcomes that deviate significantly from what is predicted based on historical data. These are often one-time anomalies that are statistically irrelevant and may not indicate a systemic issue.
超出預期的結(jié)果，也稱為非典型/異常/異常/意外結(jié)果，是指與根據(jù)歷史數(shù)據(jù)預測的結(jié)果明顯不同的測試結(jié)果。這些通常是一次性異常，在統(tǒng)計上無關(guān)緊要，可能并不表示系統(tǒng)性問題。
OOE results are usually characterized as atypical findings that are not consistent with other data, but they don’t necessarily violate specification limits like an OOS result. Depending on the circumstances and potential impact, these results may not require a rigorous multiphase investigation like OOS results.
OOE結(jié)果通常被描述為與其他數(shù)據(jù)不一致的非典型發(fā)現(xiàn)，但它們不一定像 OOS結(jié)果那樣違反規(guī)格限制。根據(jù)具體情況和潛在影響，這些結(jié)果可能不需要像OOS結(jié)果那樣進行嚴格的多階段調(diào)查。
OOE results usually prompt a review to confirm if there was any error in testing or if there are any implications for product quality. They may not lead to regulatory reporting but are important for internal quality control and process optimization.
OOE結(jié)果通常會促使審核確認測試是否存在任何錯誤或是否對產(chǎn)品質(zhì)量有任何影響。它們可能不會導致監(jiān)管報告，但對于內(nèi)部質(zhì)量控制和流程優(yōu)化很重要。
Just like with OOS and OOT results, effective management of OOE results helps in minimizing the risk of product recalls or regulatory sanctions, and ultimately supports the continuous improvement of the quality control and manufacturing processes in the pharmaceutical industry.
與OOS和OOT 結(jié)果一樣，對OOE結(jié)果的有效管理有助于最大限度地降低產(chǎn)品召回或監(jiān)管制裁的風險，并最終支持制藥行業(yè)質(zhì)量控制和制造流程的持續(xù)改進。
OOE Key Aspects:OOE 關(guān)鍵方面：
Results deviate significantly from statistical and historical predictions
結(jié)果與統(tǒng)計和歷史預測有很大偏差
Usually characterized by a one-time occurrence
通常以一次性發(fā)生為特征
Regulatory reporting may not be needed
可能不需要監(jiān)管報告
