Introduction:

An education strategy was employed in our department to increase the rate of patients with uncomplicated painful bone metastases undergoing single fractionation radiotherapy (SFRT). The purpose of this report is to analyze the results of this strategy over a 5 year period.

Materials and Methods:

In January 2015, two meetings were organized in our department. In the first, data from an audit on the current SFRT rate were shown. In the second, evidence of SFRT efficacy in the relief of pain from uncomplicated bone metastases was presented. In addition, during the weekly discussion of clinical cases, the opportunity to use the SFRT was systematically recalled. Using our institutional database, all patients treated with radiotherapy for uncomplicated painful bone metastases in the period between 2014 (year considered as a reference) and 2019 were retrieved. Data regarding treatment date (year), radiotherapy fractionation, and tumor, patients, and radiation oncologists characteristics were collected.

Results:

A total of 627 patients were included in the analysis. The rate of patients undergoing SFRT increased from 4.0% in 2014 to 63.5% in 2019 (p < 0.001). At multivariable analysis, the delivery of SFRT was significantly correlated with older patients age (>80 years), lung cancer as the primary tumor, treatment prescribed by a radiation oncologist dedicated to palliative treatments, and treatment date (2014 vs 2015–2019).

Conclusions:

This retrospective single-center analysis showed that a simple but intensive and prolonged departmental education strategy can increase the rate of patients treated with SFRT by nearly 16 times.

强化教育干预显着提高了单次放射治疗在非复杂性骨转移中的采用率

介绍：

我们部门采用了一种教育策略来提高单纯性疼痛性骨转移患者接受单次分割放射治疗 (SFRT) 的比例。本报告的目的是分析该战略在 5 年内的结果。

材料和方法：

2015年1月，我系组织了两次会议。首先，显示了对当前 SFRT 率的审计数据。其次，提出了 SFRT 在缓解单纯性骨转移疼痛方面的疗效证据。此外，在每周对临床病例的讨论中，系统地回顾了使用 SFRT 的机会。使用我们的机构数据库，检索了 2014 年（作为参考年份）至 2019 年期间接受放射治疗的简单疼痛骨转移瘤的所有患者。收集了有关治疗日期（年）、放疗分割以及肿瘤、患者和放射肿瘤学家特征的数据。

结果：

共有 627 名患者被纳入分析。接受 SFRT 的患者比例从 2014 年的 4.0% 增加到 2019 年的 63.5%（p  < 0.001）。在多变量分析中，SFRT 的实施与老年患者的年龄（>80 岁）、肺癌作为原发性肿瘤、放射肿瘤科医生开具的姑息治疗处方和治疗日期（2014 年 vs 2015-2019 年）显着相关。

结论：

这项回顾性单中心分析表明，简单但强化和长期的科室教育策略可以将接受 SFRT 治疗的患者比例提高近 16 倍。
