To explore the application of the Model for Improvement (MFI) in the procedure of preoperative diagnosis of breast ultrasound.

Consecutive patients with breast lesions who had a preoperative diagnosis by breast ultrasound were divided into either a study group (50 patients, from July to October 2019) or a control group (50 patients, from January to April 2019). In the study group, MFI was developed and used, which involved a series of actions such as on-site review by specialized doctors, training enhancement of specialized doctors, improvement of appointment procedures, etc. In the control group, no intervention was performed. The diagnostic accuracy rate, rate of undetermined diagnosis, appointment time, and number of hospital visits were compared between two groups.

The diagnostic accuracy rates of the study and control groups were 91.7% and 70.5%, and the rates of undetermined diagnosis were 4.0% and 12.0%, respectively, with significantly statistical differences between the two groups (P＜0.05). The appointment time of the study and control group was (0.58±0.99) days and (5.76±2.35) days, and the number of hospital visits was 1.38±0.63 and 2.52±0.67, respectively, with significantly statistical differences between the two groups (P＜0.05).

MFI can optimize the procedure of preoperative diagnosis of breast ultrasound, make full use of the limited medical resources, and benefit more patients.
