Evaluation of diffuse technologies: the case of digital imaging networks

Area of Science:

• Health technology assessment
• Health informatics
• Systems engineering

Background:

• Evaluating health technologies has advanced, but complex, hybrid technologies pose significant challenges.
• These 'diffuse' technologies combine multiple elements with varying costs and effects across services.
• Computer networks in healthcare exemplify diffuse technologies where holistic evaluation is unclear.

Purpose of the Study:

• To propose a framework for evaluating diffuse health technologies.
• To address the difficulties in assessing technologies that are greater or lesser than the sum of their parts.
• To illustrate evaluation principles with a practical example.

Main Methods:

• Development of a seven-stage framework for diffuse technology evaluation.
• Utilizing Picture Archiving and Communication Systems (PACS) as a case study.
• Applying general evaluation principles to a specific complex health technology.

Main Results:

• A structured, seven-stage framework is outlined for evaluating diffuse technologies.
• The framework provides a method to assess the overall value of complex health systems.
• The PACS example demonstrates the practical application of the proposed evaluation method.

Conclusions:

• Diffuse technologies require specialized evaluation frameworks due to their complexity.
• The proposed seven-stage framework offers a systematic approach to assessing these technologies.
• Effective evaluation of diffuse technologies like PACS is crucial for optimizing healthcare delivery.
