Abstract: Objective To understand the development of breast multidisciplinary treatment(MDT)in tertiary hospitals in Shandong Province, and to promote the standardisation of MDT. Methods A simple random sampling was conducted on 38 tertiary hospitals in Shandong Province. A questionnaire survey was conducted to collect basic information on doctors, hospitals, MDT implementation, and MDT evaluation. The collected data underwent statistical analysis. Results A total of 35 hospitals(92.1%)established breast surgery services, while 17 and 13 established breast imaging and pathology subspecialties, respectively. It is noteworthy that 73.7% of the hospitals have been conducting MDTs for 3 to 10 years, and 47.4% were conducting weekly MDTs. All eight hospitals with well-established subspecialties had been conducting MDTs for more than five years, whereas only three hospitals without two major subspecialties had been conducting MDTs for more than five years. Hospitals with well-established subspecialties had a higher proportion of weekly MDTs. About 94.5% of the respondents believed that MDT optimised clinical diagnosis and treatment, 97.2% supported the establishment of an MDT database, but only 43.6% of hospitals have established a database. Furthermore, 88.2% of the respondents were satisfied with the MDT remuneration, and the difference in the distribution of the respondents satisfaction with different job titles was not statistically significant. Conclusion Breast MDT in tertiary hospitals in Shandong Province has developed earlier, but still needs to be improved continuously, and in the future, it needs to mobilise the enthusiasm of medical workers and further standardise and promote it.
