Extraneous distractions may influence the flow of general practice consultations. This study piloted a methodology to examine the impact of interrupting general practitioners (GPs) while consulting actor-patients.
Six GPs were video recorded consulting six actor-patients each presenting a different clinical scenario in a simulated surgery. Five cases presented red flag cancer symptoms. Half the consultations were interrupted. Two independent assessors, blinded to the occurrence of interruptions, assessed consultation performance using the Leicester Assessment Package (LAP) for clinical competence.
24 of 36 consultations were video recorded with sufficient audio-visual clarity to allow scoring. The association between LAP score and three variables could be studied: a variety of interruptions, different GPs and various scenarios. Agreement between assessors on GP performance was poor and showed an increased bias with increasing LAP score. Despite this, the interruption did not significantly impact on assessor LAP scores (Mean difference: 0.22, P = 0.83) even after controlling for assessor, different GPs and scenarios.
Extraneous distractions had no impact on GP performance in this underpowered pilot study, a conclusion which needs to be confirmed in a larger study. However several important lessons were learned. Recorded actor-patient clinical sessions are logistically challenging. GPs whose skills were not previously assessed were working in unfamiliar surroundings dealing with relatively straight forward diagnostic challenges and may have anticipated the interruptions. In a redesign of this experiment it may be possible to eliminate some of these limitations.
外部干扰可能会影响全科医疗咨询的流程。本研究试点了一种方法,以检验在全科医生(GP)为模拟患者进行咨询时打断他们所产生的影响。
对六位全科医生为六位模拟患者进行咨询的过程进行录像,每位模拟患者呈现不同的临床场景,在模拟诊室中进行。五个病例呈现出癌症的警示症状。一半的咨询过程被打断。两位独立评估人员在不知道是否有打断情况的前提下,使用莱斯特评估包(LAP)对临床能力进行评估,以评价咨询表现。
36次咨询中有24次的录像具备足够清晰的视听效果以供评分。可以研究LAP评分与三个变量之间的关联:多种打断情况、不同的全科医生以及各种场景。评估人员之间对全科医生表现的一致性较差,并且随着LAP评分的增加偏差增大。尽管如此,即使在控制了评估人员、不同的全科医生和场景之后,打断对评估人员的LAP评分也没有显著影响(平均差异:0.22,P = 0.83)。
在这项样本量不足的试点研究中,外部干扰对全科医生的表现没有影响,这一结论需要在更大规模的研究中得到证实。然而,我们也吸取了一些重要教训。录制模拟患者的临床问诊在后勤方面具有挑战性。之前未评估过技能的全科医生在不熟悉的环境中处理相对简单的诊断挑战,并且可能已经预料到了打断情况。在重新设计这个实验时,有可能消除其中一些限制。
