To determine the feasibility of conducting a definitive randomised control trial (RCT) to answer the following questions: (1) Is early physiotherapy treatment acceptable and feasible for patients and direct healthcare providers? and (2) Is early physiotherapy intervention associated with better disability and psychosocial outcomes compared with the practice of routine MRIs?
In a feasibility RCT in Riyadh City from 01 March 2018 until 29 July 2018, chronic low back pain (CLBP) patients presenting to spine clinics were randomised to receive an MRI (intervention) plus physiotherapy rehabilitation or physiotherapy alone (control group). The acceptability of randomisation to the control group (non-MRI) was tested during the recruitment by qualitatively interviewing study participants and referring physicians. Moreover, interviews with study participants explored the broader social, political, economic, and environmental (context) aspects that may influence trial delivery and intervention implementation.
The recruitment target was not met: 16/24 (66%) participants were recruited in 4 months (12.4% of those screened); 33% declined. The process evaluation identified numerous factors that may affect the success of a definitive RCT in Saudi Arabia. These were research resources, the lack of research infrastructure to support recruitment to trials, limited research capacity in terms of knowledge and skills of the healthcare team, and limited funding.
A definitive RCT to test the influence of MRI diagnosis on the psychosocial and disability outcomes in people with CLBP treated with physiotherapy in Saudi Arabia is feasible. However, the lack of research infrastructure, research capacity, the impact of MRI on patient outcomes, and a lack of clinical equipoise in the treatment and management of CLBP in Saudi Arabia pose major barriers to clinical trials.
确定开展一项确定性随机对照试验(RCT)以回答以下问题的可行性:(1)早期物理治疗对患者和直接医疗服务提供者而言是否可接受且可行?(2)与常规MRI检查的做法相比,早期物理治疗干预是否与更好的功能障碍和心理社会结局相关?
在利雅得市于2018年3月1日至2018年7月29日开展的一项可行性RCT中,前往脊柱诊所就诊的慢性下腰痛(CLBP)患者被随机分为接受MRI检查(干预)加物理治疗康复或仅接受物理治疗(对照组)。在招募期间,通过对研究参与者和转诊医生进行定性访谈,测试对照组(非MRI检查)对随机分组的可接受性。此外,对研究参与者的访谈探讨了可能影响试验实施和干预措施执行的更广泛的社会、政治、经济和环境(背景)方面。
未达到招募目标:在4个月内招募了16/24(66%)名参与者(占筛查人数的12.4%);33%的人拒绝参与。过程评估确定了许多可能影响在沙特阿拉伯开展确定性RCT成功的因素。这些因素包括研究资源、缺乏支持试验招募的研究基础设施、医疗团队在知识和技能方面的研究能力有限以及资金有限。
在沙特阿拉伯开展一项确定性RCT以测试MRI诊断对接受物理治疗的CLBP患者心理社会和功能障碍结局的影响是可行的。然而,缺乏研究基础设施、研究能力、MRI对患者结局的影响以及沙特阿拉伯在CLBP治疗和管理方面缺乏临床 equipoise,对临床试验构成了重大障碍。
