Best practice in symptom assessment: a review

Area of Science:

• Gastroenterology
• Clinical Symptomatology
• Health Outcomes Research

Background:

• Symptom assessment is vital for diagnosing gastro-oesophageal reflux disease (GORD).
• It is also essential for monitoring patient response to therapeutic interventions.
• High-quality symptom data are needed for effective clinical decision-making.

Purpose of the Study:

• To outline the key quality aims for symptom assessment in GORD.
• To discuss important considerations in the methodology of symptom assessment.
• To emphasize the importance of valid, reliable, and responsive symptom data.

Main Methods:

• Review of established principles in clinical symptom assessment.
• Discussion of data quality attributes: validity, reliability, bias, discrimination, and responsiveness.
• Consideration of practical aspects: assessor, data collection method, timing, and multi-symptom assessment.

Main Results:

• Defined key quality attributes for symptom assessment: validity, reliability, unbiasedness, discrimination, and responsiveness.
• Highlighted critical factors influencing assessment quality, including the assessor, data collection methods, and timing.
• Emphasized the need for systematic approaches to assess multiple symptoms effectively.

Conclusions:

• Robust symptom assessment is fundamental for accurate GORD diagnosis and effective treatment evaluation.
• Adherence to quality aims ensures that symptom data are meaningful and actionable.
• Methodological considerations are crucial for optimizing the utility of symptom assessment in clinical practice.
