Objective:To develop scientific and practical sensitive indicators with its own characteristics for nursing quality of breast specialty.Methods:A research team was established in August 2018, which searched the databases both at home and abroad, screened and identified relevant literatures according to John Hopkins' evidence level and quality evaluation standards. A sensitive indicator framework for nursing quality of breast specialty was preliminarily formed based on the indicators involved in the literatures. In January 2019, the expert correspondence questionnaire was prepared. Twenty experts were randomly selected from the Qingdao Medical Doctors Association and the Nursing Experts Committee and received two rounds of correspondence consultations using the Delphi method in order to build, modify and confirm the sensitive indicator system for nursing quality of breast specialty.Results:The authority coefficients of the experts in the two rounds of consultation were 0.815 and 0.858; the expert authority coefficient was> 0.80; and the coefficient of variation of each indicator was< 0.30. Eleven sensitive indicators for nursing quality of breast specialty including the awareness rate of functional exercise of the affected limb and lymphedema prevention measures were developed.Conclusions:The sensitive indicators of nursing quality of breast specialty based on the Delphi method is highly practical and credible, which have distinctive specialty characteristics, may be used for the overall care quality assessment and management of breast disease patients, and provide accurate and scientific evaluation for clinical nursing work.
