多学科骨科肿瘤会议对发展可疑骨和软组织肿瘤的患者的治疗计划至关重要，需要涉及几个服务的医生。过去的研究显示了这些会议的临床价值;然而，放射学输入对管理计划的影响以及放射学人员参加这些会议的时间成本尚未得到充分研究。(1) 多学科会议中的放射学输入能否指导临床管理并提高临床医生的信心水平？(2) 多学科会议的放射学输入时间成本是多少？此前研究调查了2020年10月至2022年3月在一所医学院校肉瘤中心进行的前瞻性研究。每个患者的单个数据问卷在每周的多学科会议上与三名治疗骨科肿瘤学家进行放射学讨论后发送。治疗骨科肿瘤学家的数据问卷完成了322名患者的调查，占这三位骨科肿瘤学家的患者比例(672人中的322人)。每个多学科会议都由一个肌肉骨骼放射学医师和一个肌肉骨骼专科放射学医师提供放射学输入。记录了临床计划(不动、随访影像、临床随访、建议不同的影像检查、穿刺活检、手术切除或活检或固定、或其他)和放射学输入前后的临床信心变化。每周向放射学医师发送第二个数据问卷，以估算多学科会议的放射学输入的时间成本。在322例患者中，有29％(93例)的患者在放射学输入后临床计划发生了变化，80例需要穿刺活检的患者中有30％(24例)取消了穿刺活检，72例需要手术切除的患者中有24％(17例)取消了手术切除。在322例患者中，有未报告的影像所发现的病变，影响了诊治; 13％(43例)的患者发现漏掉了，8％(25例)的患者的影像发现被错误解释。在诊疗计划的最终信心方面，322名患者中有78％(251名)的患者由治疗骨科肿瘤学家参加多学科会议后治疗信心提高了。放射学研究员和出勤医师在每周的多学科会议上平均花费4.2小时和1.5小时进行审核和演示。根据出勤医师的全国中位数薪资数据和研究员内部工资数据，估计出勤医师和研究员的年度综合摊销时间成本为24,310美元。在一项在一所三级保健肿瘤中心进行的研究中，多学科会议中放射学出勤医师和研究员的输入有助于指导最终的治疗计划，减少手术，提高临床医生对最终治疗计划的信心，其年度时间成本为24,310美元。多学科骨科肿瘤会议可以导致管理计划的变化，并且放射学部门或母机构应该为放射学人员的时间成本做好预算。版权所有©2023年《骨科医师协会》。

Multidisciplinary orthopaedic oncology conferences are important in developing the treatment plan for patients with suspected orthopaedic bone and soft tissue tumors, involving physicians from several services. Past studies have shown the clinical value of these conferences; however, the impact of radiology input on the management plan and time cost for radiology to staff these conferences has not been fully studied.(1) Does radiology input at multidisciplinary conference help guide clinical management and improve clinician confidence? (2) What is the time cost of radiology input for a multidisciplinary conference?This prospective study was conducted from October 2020 to March 2022 at a tertiary academic center with a sarcoma center. A single data questionnaire for each patient was sent to one of three treating orthopaedic oncologists with 41, 19, and 5 years of experience after radiology discussion at a weekly multidisciplinary conference. A data questionnaire was completed by the treating orthopaedic oncologist for 48% (322 of 672) of patients, which refers to the proportion of those three oncologists' patients for which survey data were captured. A musculoskeletal radiology fellow and musculoskeletal fellowship-trained radiology attending physician provided radiology input at each multidisciplinary conference. The clinical plan (leave alone, follow-up imaging, follow-up clinically, recommend different imaging test, core needle biopsy, surgical excision or biopsy or fixation, or other) and change in clinical confidence before and after radiology input were documented. A second weekly data questionnaire was sent to the radiology fellow to estimate the time cost of radiology input for the multidisciplinary conference.In 29% (93 of 322) of patients, there was a change in the clinical plan after radiology input. Biopsy was canceled in 30% (24 of 80) of patients for whom biopsy was initially planned, and surgical excision was canceled in 24% (17 of 72) of patients in whom surgical excision was initially planned. In 21% (68 of 322) of patients, there were unreported imaging findings that affected clinical management; 13% (43 of 322) of patients had a missed finding, and 8% (25 of 322) of patients had imaging findings that were interpreted incorrectly. For confidence in the final treatment plan, 78% (251 of 322) of patients had an increase in clinical confidence by their treating orthopaedic oncologist after the multidisciplinary conference. Radiology fellows and attendings spent a mean of 4.2 and 1.5 hours, respectively, reviewing and presenting at a multidisciplinary conference each week. The annual combined prorated time cost for the radiology attending and fellow was estimated at USD 24,310 based on national median salary data for attendings and internal salary data for fellows.In a study taken at one tertiary-care oncology program, input from radiology attendings and fellows in the setting of a multidisciplinary conference helped to guide the final treatment plan, reduce procedures, and improve clinician confidence in the final treatment plan, at an annual time cost of USD 24,310.Multidisciplinary orthopaedic oncology conferences can lead to changes in management plans, and the time cost to the radiologists should be budgeted for by the radiology department or parent institution.Copyright © 2023 by the Association of Bone and Joint Surgeons.
