International Validation of EORTC PATSAT-C33 and OUT-PATSAT7 in Phase IV Cancer Care Studies

Overview

This international multicenter prospective study validated the EORTC PATSAT-C33 core questionnaire and the OUT-PATSAT7 outpatient module for assessing patient satisfaction with cancer care. The study confirmed the cross-cultural applicability, acceptability, and psychometric robustness of these tools across diverse cancer care settings and countries.

Background

Patient satisfaction is a critical patient-reported experience measure reflecting patients' evaluations of healthcare delivery, particularly important in oncology due to the physical and psychosocial burden of cancer. The EORTC previously developed the IN-PATSAT32 for inpatient satisfaction, which has now been revised to include outpatient settings via the PATSAT-C33 core questionnaire and the OUT-PATSAT7 module. This study represents the final phase of validation, focusing on cross-cultural applicability and comprehensive psychometric assessment in a large international cohort.

Data Highlights

Patients were recruited from 20 centers across 12 countries representing five cultural/geographical areas. Assessments were conducted at up to three time points (T1, T2, T3) with questionnaires including EORTC PATSAT-C33, OUT-PATSAT7, and EORTC QLQ-C30. Inclusion criteria required adult cancer patients proficient in the local language, excluding those with severe psychiatric or cognitive disorders. Data collected included socio-demographics, clinical characteristics, and patient-reported satisfaction and quality of life measures.

Key Findings

• The EORTC PATSAT-C33 and OUT-PATSAT7 questionnaires demonstrated strong cross-cultural validity across diverse countries and languages.
• High acceptability and completion rates were observed, with reminders improving questionnaire return.
• Psychometric analyses confirmed reliability and validity of the questionnaires in assessing patient satisfaction in outpatient oncology settings.
• Patient satisfaction scores correlated with clinical variables and quality of life measures, supporting construct validity.
• The tools effectively captured satisfaction related to various outpatient treatments including chemotherapy, radiotherapy, and surveillance consultations.

Clinical Implications

These validated questionnaires provide reliable instruments for assessing patient satisfaction in outpatient cancer care internationally, enabling clinicians and researchers to monitor and improve service quality. Incorporating these tools into routine practice can help identify areas for care enhancement, potentially improving treatment adherence and clinical outcomes.

Conclusion

The EORTC PATSAT-C33 core questionnaire and OUT-PATSAT7 outpatient module are psychometrically sound, culturally adaptable tools for measuring patient satisfaction in oncology outpatient settings worldwide. Their use supports patient-centered care and quality improvement initiatives in cancer treatment.
