Education in simulated learning environments (SLEs) has grown rapidly across health care professions, yet no substantive randomised controlled trial (RCT) has investigated whether SLEs can, in part, substitute for traditional clinical education.
Participants were physiotherapy students (RCT 1, n = 192; RCT 2, n = 178) from six Australian universities undertaking clinical education in an ambulatory care setting with patients with musculoskeletal disorders. A simulated learning programme was developed as a replica for clinical education in musculoskeletal practice to replace 1 week of a 4-week clinical education placement. Two SLE models were designed. Model 1 provided 1 week in the SLE, followed by 3 weeks in clinical immersion; Model 2 offered training in the SLE in parallel with clinical immersion during the first 2 weeks of the 4-week placement. Two single-blind, multicentre RCTs (RCT 1, Model 1; RCT 2, Model 2) were conducted using a non-inferiority design to determine if the clinical competencies of students part-educated in SLEs would be any worse than those of students educated fully in traditional clinical immersion. The RCTs were conducted simultaneously, but independently. Within each RCT, students were stratified on academic score and randomised to either the SLE group or the control ('Traditional') group, which undertook 4 weeks of traditional clinical immersion. The primary outcome measure was a blinded assessment of student competency conducted over two clinical examinations at week 4 using the Assessment of Physiotherapy Practice (APP) tool.
Students' achievement of clinical competencies was no worse in the SLE groups than in the Traditional groups in either RCT (Margin [Δ] ≥ 0.4 difference on APP score; RCT 1: 95% CI - 0.07 to 0.17; RCT 2: 95% CI - 0.11 to 0.16).
These RCTs provide evidence that clinical education in an SLE can in part (25%) replace clinical time with real patients without compromising students' attainment of the professional competencies required to practise.
模拟学习环境(SLE)中的教育在医疗保健专业中迅速发展,但尚无实质性的随机对照试验(RCT)调查 SLE 是否可以部分替代传统的临床教育。
来自澳大利亚六所大学的物理治疗专业学生(RCT 1,n=192;RCT 2,n=178)参与了门诊环境中肌肉骨骼疾病患者的临床教育。开发了一个模拟学习计划,作为肌肉骨骼实践临床教育的复制品,以替代为期 4 周的临床教育安置中的 1 周。设计了两种 SLE 模型。模型 1 在 SLE 中进行 1 周,然后在临床沉浸中进行 3 周;模型 2 在临床沉浸的前 2 周内与临床沉浸同时提供 SLE 培训。进行了两项单盲、多中心 RCT(RCT 1,模型 1;RCT 2,模型 2),采用非劣效性设计来确定部分接受 SLE 教育的学生的临床能力是否会比完全接受传统临床沉浸教育的学生更差。这两项 RCT 同时进行,但独立进行。在每项 RCT 中,根据学术成绩对学生进行分层,并将他们随机分配到 SLE 组或对照组(传统组),传统组接受为期 4 周的传统临床沉浸。主要结局测量是在第 4 周通过使用物理治疗实践评估(APP)工具进行的两次临床检查对学生能力进行的盲法评估。
在这两项 RCT 中,SLE 组学生的临床能力表现并不比传统组差(APP 评分差异≥0.4;RCT 1:95%CI-0.07 至 0.17;RCT 2:95%CI-0.11 至 0.16)。
这些 RCT 提供了证据表明,在 SLE 中进行临床教育可以部分(25%)替代与真实患者的临床时间,而不会影响学生获得从事专业所需的能力。
