International Prospective Validation of the EORTC Core Questionnaire for Patient Satisfaction (EORTC PATSAT-C33) and the Outpatient Module (EORTC OUT-PATSAT7) in Phase IV Studies

Category	Detail
Condition	Cancer patient satisfaction with care
Key Mechanisms	Assessment of patient satisfaction as patient-reported experience measures (PREMs) using validated questionnaires addressing inpatient and outpatient oncology care
Target Population	Adult cancer patients (≥18 years) receiving inpatient or outpatient oncology care across multiple countries
Care Setting	Inpatient wards, outpatient radiotherapy, chemotherapy, oncology consultations

Patient satisfaction reflects patients’ value judgments on healthcare delivery and is linked to treatment adherence and clinical outcomes in cancer care.
The EORTC PATSAT-C33 core questionnaire and OUT-PATSAT7 outpatient module were developed and cross-culturally validated in a large international prospective phase IV study.
The study included 12 countries with diverse cultural/geographical areas and assessed psychometric properties, acceptability, and applicability of the questionnaires.

Use EORTC PATSAT-C33 to assess patient satisfaction in both inpatient and outpatient oncology settings.
Use EORTC OUT-PATSAT7 module specifically for outpatient cancer care satisfaction assessment.

Incorporate patient satisfaction assessments to identify areas for care improvement and service development in oncology.
Administer questionnaires at multiple time points during and after treatment to monitor satisfaction longitudinally.

Repeat assessments at baseline, shortly after treatment, and at one year to evaluate changes in satisfaction and perceived quality of care.
Use reminders to improve questionnaire return rates and data completeness.

Exclude patients with severe psychiatric disorders or major cognitive dysfunctions to ensure reliable self-reporting.
Be aware of potential missing data if questionnaires are not returned within one month.

Adult cancer patients undergoing various cancer treatments including chemotherapy, radiotherapy, biological therapy, and surveillance.

Patient satisfaction assessment complements clinical outcome measures and can guide personalized care improvements and adherence strategies.

Ensure cultural and linguistic appropriateness of satisfaction questionnaires by cross-cultural validation.
Collect comprehensive socio-demographic and clinical data to contextualize satisfaction scores.
Use standardized questionnaires (EORTC QLQ-C30, PATSAT-C33, OUT-PATSAT7) alongside debriefing questions for robust assessment.
Obtain informed consent and ethical approvals according to local regulations.
Implement systematic follow-up and reminders to maximize data collection completeness.
