Knowledge of the readiness for hospital discharge can help health care professionals accurately determine the patients' discharge time. However, few studies were on the readiness for discharge and its related factors among mothers with cesarean sections. Thus, this study aims to examine the readiness for hospital discharge and its associated factors among Chinese mothers with cesarean sections. Patients and Methods: A single-centre cross-sectional study was conducted from September 2020 to March 2021 in Guangzhou, China. Three hundred thirty-nine mothers with cesarean sections completed the questionnaires on demographic and obstetric characteristics, readiness for hospital discharge, quality for discharge teaching, parenting sense of competence, family function, and social support. Multiple linear regression analysis was used to identify independent factors influencing readiness for hospital discharge among mothers with cesarean sections. Results: The total score of readiness for hospital discharge was 136.47 ± 25.29. The quality of discharge teaching, parenting sense of competence, number of cesareans, family function, and attending antenatal classes were independent factors influencing the readiness for hospital discharge (P < 0.05) among mothers with cesarean sections. Conclusion:The readiness for hospital discharge of mothers with cesarean sections need to be improved. Improving the quality of discharge teaching, parenting sense of competence, and family function may help improve the readiness for hospital discharge of mothers with cesarean sections.
