Development and Validation of a Chinese Version of the Readiness for Hospital Discharge Instrument After Initial Invasive Percutaneous Transhepatic Biliary Drainage: A Methodological Study.

The sample came from one tertiary hospital in Suzhou, China, so results may not apply to other settings or countries. The factor structure was explored in the same 224 patients and was not confirmed in an independent sample. The questionnaire was not tested for stability over time with a test-retest design. Thirty-six of 260 completed surveys were excluded for missing data, leaving 224 analysed. Participants were required to have liver or bile duct cancer and normal comprehension, so it does not cover all patients with biliary drains. The study evaluated preliminary psychometric properties, not whether the questionnaire predicts complications or readmission.

The study was funded by the Second Affiliated Hospital of Soochow University, and the authors declared no conflicts of interest.

Do not conclude that this questionnaire improves discharge or reduces readmission. The paper reports only consistency and factor results, not patient outcomes.
