成功采用临床决策支持系统（CDSS）的一个关键要求是，它们能够为用户提供任何给定建议的可靠解释，这对于某些任务（如伤口管理决策）可能具有挑战性。尽管有丰富的决策指南，但通常提供大多数治疗的伤口非专家（以下称为新手）临床医生仍然具有决策不确定性。我们的目标是评估Wound CDSS智能手机应用程序的使用，该应用程序为其产生的建议提供解释。该应用程序利用新手临床医生使用智能手机摄像头拍摄的伤口图像。本研究实验与两个拟议的变化，称为动词为基础的和gist为基础的规则跟踪解释。根据决策理论推导，不像以前的文献说，规则跟踪的解释只首选新手，我们假设，规则跟踪的解释是首选的两个临床医生，但在不同的形式：新手更喜欢动词为基础的规则跟踪和专家更喜欢gist为基础的规则跟踪。
A key requirement for the successful adoption of clinical decision support systems (CDSS) is their ability to provide users with reliable explanations for any given recommendation which can be challenging for some tasks such as wound management decisions. Despite the abundance of decision guidelines, wound non-expert (novice hereafter) clinicians who usually provide most of the treatments still have decision uncertainties. Our goal is to evaluate the use of a Wound CDSS smartphone App that provides explanations for recommendations it produces. The App utilizes wound images taken by the novice clinician using smartphone camera. This study experiments with two proposed variations of rule-tracing explanations called verbose-based and gist-based. Deriving upon theories of decision making, and unlike prior literature that says rule-tracing explanations are only preferred by novices, we hypothesize that, rule-tracing explanations are preferred by both clinicians but in different forms: novices prefer verbose-based rule-tracing and experts prefer gist-based rule-tracing.
