Aims and Objectives
To conduct the initial development and validation of a Chinese readiness for hospital discharge instrument for patients after initial invasive percutaneous transhepatic biliary drainage (PTBD).
Background
The Readiness for Hospital Discharge Scale (RHDS) is a generic measure and may not fully capture PTBD‐specific readiness, particularly catheter‐related self‐management (e.g., tube securement, bile output monitoring, skin care and early recognition of catheter‐related complications) in Chinese‐speaking populations. A PTBD‐specific instrument may support more targeted discharge preparation and follow‐up.
Design
A methodological study.
Methods
The instrument was developed using a five‐stage process. An initial pool of 33 items was generated from the literature review and existing instruments. After two rounds of expert consultation, two items were deleted, six items were added and several items were revised or merged, resulting in a 35‐item pool. Item analysis and exploratory factor analysis were then conducted to reduce items and examine preliminary construct validity.
Results
A total of 224 patients completed the instrument and were included for further analysis. Item analysis led to the deletion of one item, resulting in a 34‐item instrument. Exploratory factor analysis revealed that 22 items remained in four factors (personal status, knowledge, coping ability and expected support), which accounted for 77.84% of the variance. The Cronbach's α coefficient of the instrument was 0.962, and the split‐half reliability was 0.912.
Conclusion
The Chinese version of the readiness for hospital discharge instrument after invasive PTBD consists of 22 items across four subscales and provides preliminary evidence of content validity, preliminary construct validity, internal consistency and split‐half reliability.
Relevance to Clinical Practice
This instrument may help healthcare professionals assess discharge readiness before discharge among patients with PTBD catheters and identify areas requiring targeted discharge preparation, catheter‐related education and follow‐up support. Scholars in Chinese‐speaking regions may find this culturally compatible instrument useful when conducting studies related to readiness for hospital discharge.
Patient or Public Contribution
Two hundred twenty‐four participants provided their perspectives on readiness for hospital discharge.
