In order to assess the readiness of patients with urostomy to be discharged from the hospital,an initial questionnaire was created by reviewing relevant guidelines,references,conducting semi-structured interviews,and creating an initial questionnaire.Then,the Delphi method was used for expert correspondence on the content of the entries for assessing the readiness of patients for dis-charge after urostomy.The results show that in the two rounds of consultation,the positive coefficients of the experts are 90.9%and 100.0%,the authority coefficients are 0.84 and 0.87,and the co-ordination coefficients are 0.341 and 0.362,respectively(all P<0.000).Eventually,a scale was developed to assess the readiness of urostomy patients to be discharged from the hospital with four di-mensions and a total of 30 entries,including physiological status,psychological status,quality of health guidance,and social support.The scale provides a scientific and effective assessment tool for healthcare professionals to improve patient self-management in the post-operative period and to reduce the incidence of complications and readmission rates.It can be seen that this assessment scale has good practicality in clinical practice and can be used as a powerful tool to assess the readiness of urostomy patients for discharge.
