The Edmonton Symptom Assessment System: Ascites Modification (ESAS:AM) is a validated tool for assessing malignant ascites symptoms in Japanese cancer patients. This reliable instrument aids in patient care and clinical research.
Area of Science:
- Oncology
- Palliative Care
- Clinical Measurement
Background:
- Patient-reported outcomes for malignant ascites symptoms are limited.
- The Edmonton Symptom Assessment System: Ascites Modification (ESAS:AM) requires validation.
Purpose of the Study:
- To validate the ESAS:AM in Japanese cancer patients.
- To assess the reliability and validity of the ESAS:AM.
Main Methods:
- Validated the ESAS:AM in 292 Japanese adult cancer patients.
- Assessed internal consistency, test-retest reliability, and concurrent/construct validity.
- Utilized Japanese versions of ESAS:AM, MDASI, EORTC QLQ-C30, and EORTC ascites subscales.
Main Results:
- ESAS:AM demonstrated high internal consistency (Cronbach's alpha = 0.89) and excellent test-retest reliability (ICC = 0.93).
- Strong correlations were found between ESAS:AM and other symptom/quality of life measures (r = 0.44–0.81, P < 0.001).
- Patients with symptomatic ascites had significantly higher ESAS:AM scores (P = 0.018).
Conclusions:
- The ESAS:AM is a reliable and valid tool for measuring malignant ascites symptoms.
- ESAS:AM can be effectively used in daily patient care.
- The validated ESAS:AM is suitable for future epidemiological studies and clinical trials.
