Triangulation in evaluation research enhances the validity and completeness of results when assessing health information and communication technologies (ICTs). This methodological approach offers significant benefits for medical informatics evaluation.

Area of Science:

  • Health Informatics
  • Evaluation Research Methodology

Background:

  • Information and communication technologies (ICTs) are integral to modern healthcare.
  • Rigorous evaluation of ICTs is crucial for decision-makers and end-users.
  • Evaluation research traditionally follows objectivistic or subjectivistic paradigms.

Purpose of the Study:

  • To explore the benefits of applying triangulation in evaluation research.
  • To demonstrate how triangulation enhances the validation and completeness of study findings.
  • To assess the impact of a computer-based nursing documentation system.

Main Methods:

  • Utilized the theory of triangulation, integrating multiple methods, data sources, observers, or theories.
  • Applied triangulation principles to analyze the effects of a specific ICT: a computer-based nursing documentation system.

Related Experiment Videos

  • Conducted a case study analysis.

    • Main Results:

    • Triangulation significantly improves the validation of evaluation results.
    • Employing triangulation enhances the completeness of findings in evaluation studies.
    • The case study illustrated practical benefits of triangulation in assessing ICT impact.

    Conclusions:

    • Triangulation is a valuable, established theory that can benefit medical informatics evaluation research.
    • Effective application of triangulation requires specialized training and methodological expertise.
    • The decision to use triangulation depends on the specific research question and requires careful consideration.
