To describe the current state and limitations to interventional radiology (IR) in Canada through a large, national survey of Canadian interventional radiologists.
An anonymous online survey was offered to members of the Canadian Interventional Radiology Association (CIRA). Only staff radiologists were invited to participate.
Seventy-five (75) responses were received from a total of 247, giving a response rate of 30%. Respondents were split approximately equally between academic centers (47%) and community practice (53%), and the majority of interventional radiologists worked in hospitals with either 200-500 (49%) or 500-1,000 (39%) beds. Procedures listed by respondents as most commonly performed in their practice included PICC line insertion (83%), angiography and stenting (65%), and percutaneous biopsy (37%). Procedures listed as not currently performed but which interventional radiologists believed would benefit their patient population included radiofrequency ablation (36%), carotid stenting (34%), and aortic stenting (21%); the majority of respondents noted that a lack of support from referring services was the main reason for not performing these procedures (56%). Impediments to increasing scope and volume of practice in Canadian IR were most commonly related to room or equipment shortage (35%), radiologist shortage (33%), and a lack of funding or administrative support (28%).
Interventional radiology in Canada is limited by a number of factors including funding, manpower, and referral support. A concerted effort should be undertaken by individual interventional radiologists and IR organizations to increase training capacity, funding, remuneration, and public exposure to IR in order to help advance the subspecialty.
通过对加拿大介入放射科医生进行大规模的全国性调查，描述加拿大介入放射学（IR）的现状和局限性。
向加拿大介入放射学会（CIRA）的成员提供了一项匿名在线调查。仅邀请放射科工作人员参与。
共收到247份回复中的75份，回复率为30%。学术中心（47%）和社区医疗机构（53%）的受访者人数大致相等，大多数介入放射科医生在拥有200 - 500张床位（49%）或500 - 1000张床位（39%）的医院工作。受访者列出的在其实践中最常进行的操作包括经外周静脉穿刺中心静脉置管（PICC）（83%）、血管造影和支架置入（65%）以及经皮活检（37%）。被列为目前未进行但介入放射科医生认为对其患者群体有益的操作包括射频消融（36%）、颈动脉支架置入（34%）和主动脉支架置入（21%）；大多数受访者指出，缺乏来自转诊服务的支持是不进行这些操作的主要原因（56%）。加拿大介入放射学扩大业务范围和工作量的障碍最常与空间或设备短缺（35%）、放射科医生短缺（33%）以及缺乏资金或行政支持（28%）有关。
加拿大的介入放射学受到多种因素的限制，包括资金、人力和转诊支持。介入放射科医生个人和介入放射学组织应共同努力，提高培训能力、资金、薪酬，并增加公众对介入放射学的了解，以推动这一亚专业的发展。
