Clinical Trials

6.6K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Area of Science:

  • Health Informatics
  • Data Science
  • Medical Research

Background:

  • Routine healthcare data offers significant potential for research.
  • Current data quality limitations hinder its effective secondary use.
  • External data enrichment is a promising strategy to improve data utility.

Purpose of the Study:

  • To demonstrate a process-driven prototyping approach for enhancing routine healthcare data.
  • To enable secure mapping of medical concepts from free text to standardized terminology codes.
  • To improve the quality and security of data for secondary research purposes.

Main Methods:

  • A prototype-oriented framework was developed through focus group discussions.
  • The framework comprises four components: Clinical Data Repository, Transition Database, Mapping Tools, and Validation Tools.
  • Sensitive and non-sensitive data were separated to ensure data protection and information security.

Main Results:

  • The approach facilitates the mapping of medical concepts in free text to standardized terminology codes.
  • Data flows between components support extract, transform, and load (ETL) processes and workflow management.
  • Quality-assured medical concepts and their mappings are generated for secondary data use.

Conclusions:

  • The demonstrated approach enhances the secondary use of routine patient data for research.
  • It provides a secure and efficient method for data enrichment and concept mapping.
  • This process-driven method significantly boosts the quality and research applicability of healthcare data.
