Summary
Laboratory accreditation and external quality assessment improve lab performance. While linking this to patient safety is complex, external evaluations remain crucial for quality assurance.
Area of Science:
- Clinical Laboratory Science
- Healthcare Quality Management
Background:
- Laboratory accreditation and external quality assessment (EQA) are established methods for evaluating laboratory quality.
- Both practices have demonstrated positive impacts on laboratory performance metrics.
Purpose of the Study:
- To examine the role of laboratory accreditation and EQA in ensuring quality.
- To discuss the challenges in linking laboratory performance directly to patient safety outcomes.
Main Methods:
- Review of existing literature on laboratory accreditation and EQA.
- Analysis of the established benefits of external quality evaluation for laboratories.
Main Results:
- Accreditation and EQA are consistently linked to improved laboratory performance.
- Directly correlating laboratory performance with patient safety is challenging due to multifactorial influences on patient outcomes.
Conclusions:
- External evaluation of laboratories, through accreditation and EQA, is essential for maintaining high standards.
- The benefits of external quality assessment in laboratory settings are too significant to disregard.

01:15Nursing Evaluation
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

01:19Pharmacovigilance
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

01:24Automated Microbial Diagnostics
Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...
01:20Nursing Process for Patient and Caregiver Teaching III: Evaluation and Documentation
Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning, patient...

01:19Quality Assurance
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...
01:25Drug Regulation
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...
