    Area of Science:

    • Health Informatics
    • Medical Information Systems
    • Clinical Data Management

    Background:

    • Computerized information systems (CIS) are promoted for enhancing clinical information management.
    • Many claims regarding CIS benefits lack robust clinical study validation.
    • Assessing the real-world impact of CIS on healthcare quality is crucial.

    Purpose of the Study:

    • To critically evaluate the scientific rigor of published studies on CIS in healthcare.
    • To determine the extent to which CIS improve the quality of medical care and patient outcomes.
    • To identify research gaps in assessing CIS effectiveness.

    Main Methods:

    • Systematic review and methodologic quality assessment of published articles on CIS in healthcare.
    • Application of predefined criteria to evaluate the scientific validity of investigations.
    • Analysis of studies focusing on improvements in the process of care and patient outcomes.

    Main Results:

    • Out of 135 articles, only 30 (22%) reported preplanned investigations; half met minimal scientific criteria.
    • Fourteen studies were well-designed and executed, reporting process-of-care improvements.
    • No studies measured significant positive changes in patient outcomes; effects were minimal or absent.

    Conclusions:

    • While CIS offer potential in clinical information management, their impact on patient outcomes remains limited.
    • Further research is essential to optimize CIS for enhanced healthcare quality and improved patient results.
    • Rigorous scientific investigation is needed to substantiate the benefits of CIS in clinical practice.
