Evidence and quality, practicalities and judgments: some experience from NICE.

Area of Science:

• Health economics
• Evidence-based medicine
• Healthcare policy

Background:

• The National Institute for Health and Clinical Excellence (NICE) is a key body for healthcare evidence appraisal in England and Wales.
• NICE defines quality by effectiveness, safety, and patient experience.

Purpose of the Study:

• To comment on the quality of evidence used by NICE regarding effectiveness, safety, and patient experience.
• To speculate on the implications of broadening NICE's appraisal scope and considering upstream health determinants.
• To analyze the type, quality, and utilization of evidence, including underlying values.

Main Methods:

• Critical commentary on existing NICE appraisal processes.
• Speculative analysis of potential changes to NICE's remit.
• Examination of evidence quality, usage, and inherent values.

Main Results:

• Concerns regarding the quality of evidence for effectiveness, safety, and patient experience.
• Potential challenges and benefits of expanding NICE's scope to include upstream health determinants.
• Identification of hidden values influencing evidence interpretation and application.

Conclusions:

• The quality of evidence underpinning NICE's recommendations requires scrutiny.
• A broader approach to health determinants and a transparent acknowledgment of values are crucial for robust healthcare appraisal.
• Further discussion is needed on refining NICE's methods to ensure comprehensive and unbiased evaluation.
