Background: The rapid aging of the Japanese population is leading to an increase in the number of patients with bone metastases. Since 2014, our orthopedics department has promoted multidisciplinary hospital activities, including offering lectures to hospital staff on multidisciplinary approaches for bone metastases and holding regular cancer board meetings on bone metastases. This study investigated whether these activities were effective in promoting multidisciplinary approaches and improving outcomes of patients with bone metastasis.
Methods: To investigate the effects of changes in medical practice on patients with bone metastases, we compared patient clinical characteristics after (January 2014 through December 2017) and before the start of the activities (January 2011 through December 2013).
Results: The semiannual numbers of first-visit, referral, and orthopedic surgical patients, the number of patients with slower growing primary cancers, and the number of patients with milder pain were significantly higher post-activity than pre-activity. The number of patients without paralysis was higher after the start of the activity than before the activity, but the difference was not significant. Survival after the first visit to the orthopedics department was significantly longer after the start of the activity than before the activity.
Conclusions: The potential demand for a multidisciplinary approach to bone metastases is high, and orthopedic specialists should actively participate in this approach.
