Adoption of innovations in the field of medicine is frequently hindered by a failure to recognize the condition targeted by the innovation. This is particularly true in cases where recognition requires integration of patient information from different sources, or where disease presentation can be heterogeneous and the recognition step may be easier for some patients than for others.
We propose a general data-driven metric for clinician recognition that accounts for the variability in patient disease severity and for institutional standards. As a case study, we evaluate the ventilatory management of 362 patients with acute respiratory distress syndrome (ARDS) at a large academic hospital, because clinician recognition of ARDS has been identified as a major barrier to adoption to evidence-based ventilatory management. We calculate our metric for the 48 critical care physicians caring for these patients and examine the relationships between differences in ARDS recognition performance from overall institutional levels and provider characteristics such as demographics, social network position, and self-reported barriers and opinions.
Our metric was found to be robust to patient characteristics previously demonstrated to affect ARDS recognition, such as disease severity and patient height. Training background was the only factor in this study that showed an association with physician recognition. Pulmonary and critical care medicine (PCCM) training was associated with higher recognition (β = 0.63, 95% confidence interval 0.46-0.80, p < 7 × 10). Non-PCCM physicians recognized ARDS cases less frequently and expressed greater satisfaction with the ability to get the information needed for making an ARDS diagnosis (p < 5 × 10), suggesting that lower performing clinicians may be less aware of institutional barriers.
We present a data-driven metric of clinician disease recognition that accounts for variability in patient disease severity and for institutional standards. Using this metric, we identify two unique physician populations with different intervention needs. One population consistently recognizes ARDS and reports barriers vs one does not and reports fewer barriers.
医学领域创新的采用常常因未能识别创新针对的病症而受阻。在需要整合来自不同来源的患者信息的情况下,或者在疾病表现可能存在异质性且识别步骤对某些患者比对其他患者更容易的情况下,尤其如此。
我们提出了一种针对临床医生识别的通用数据驱动指标,该指标考虑了患者疾病严重程度的可变性和机构标准。作为一个案例研究,我们评估了一家大型学术医院的 362 名急性呼吸窘迫综合征(ARDS)患者的通气管理,因为临床医生对 ARDS 的识别已被确定为采用基于证据的通气管理的主要障碍。我们为照顾这些患者的 48 名重症监护医生计算了我们的指标,并研究了 ARDS 识别表现与整体机构水平以及提供者特征(如人口统计学、社交网络地位以及自我报告的障碍和意见)之间的差异。
我们的指标被发现对先前被证明会影响 ARDS 识别的患者特征具有稳健性,例如疾病严重程度和患者身高。在这项研究中,培训背景是唯一与医生识别相关的因素。肺病和重症监护医学(PCCM)培训与更高的识别率相关(β=0.63,95%置信区间 0.46-0.80,p<7×10)。非 PCCM 医生识别 ARDS 病例的频率较低,并且对获得做出 ARDS 诊断所需信息的能力表示更大的满意(p<5×10),这表明表现较差的临床医生可能对机构障碍的认识较低。
我们提出了一种针对临床医生疾病识别的基于数据的指标,该指标考虑了患者疾病严重程度的可变性和机构标准。使用此指标,我们确定了具有不同干预需求的两个独特医生群体。一个群体始终识别 ARDS 并报告障碍,而另一个群体则不识别并报告较少的障碍。
