Prospective scenarios: a method of evaluating new decision tools

Area of Science:

• Medical Informatics
• Clinical Trial Design
• Health Technology Assessment

Background:

• Prospective randomized controlled trials (RCTs) present challenges for evaluating novel decision-making techniques.
• Existing methodologies may not be optimal for assessing the real-world impact of new clinical tools.

Purpose of the Study:

• To introduce and justify a pragmatic approach for evaluating new decision-making techniques.
• To enable more rapid analysis of the effectiveness of innovative clinical strategies.

Main Methods:

• A cohort of patients follows the standard care pathway until the point of decision-making.
• Conventional decision rules are applied, and outcomes are recorded.
• The new decision-making technique is then applied to the same cohort, and outcomes are re-evaluated.

Main Results:

• This approach allows for a quicker assessment of the new technique's impact compared to traditional RCTs.
• It provides a logical and statistical framework for comparative analysis.
• While potentially less pure than RCTs, it offers a more feasible evaluation method.

Conclusions:

• The described method offers a viable and efficient alternative for evaluating new decision-making techniques in clinical practice.
• This approach facilitates faster evidence generation for health technology adoption.
• It balances the need for rapid evaluation with statistical rigor.
