Quality Assurance01:19

Quality Assurance

3.8K
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...

Quality Control01:05

Quality Control

4.1K
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Comparing the Survival Analysis of Two or More Groups

692
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Archival Research01:40

Archival Research

17.5K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

520
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Naturalistic Observations02:30

Naturalistic Observations

17.9K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Summary

Action research and audit initiatives share surface similarities but possess distinct underlying goals, processes, and funding. Understanding these key differences is crucial for effective implementation in quality assurance.

Area of Science:

  • Healthcare improvement methodologies
  • Research and quality assurance in medicine

Background:

  • Action research and audit share superficial commonalities in healthcare settings.
  • Despite similarities, fundamental distinctions exist between these approaches.

Purpose of the Study:

  • To delineate the core differences between action research and audit/quality assurance.
  • To provide a clear distinction for researchers and practitioners in healthcare improvement.

Main Methods:

  • Comparative analysis of action research and audit.
  • Examination of background, goals, processes, data collection, motivation, and funding.

Main Results:

  • Identified fundamental differences in the foundational aspects of action research versus audit.
