To describe the characteristics of unanswered clinical questions and propose interventions that could improve the chance of finding answers.
In a previous study, investigators observed primary care physicians in their offices and recorded questions that arose during patient care. Questions that were pursued by the physician, but remained unanswered, were grouped into generic types. In the present study, investigators attempted to answer these questions and developed recommendations aimed at improving the success rate of finding answers.
Frequency of unanswered question types and recommendations to increase the chance of finding answers.
In an earlier study, 48 physicians asked 1062 questions during 192 half-day office observations. Physicians could not find answers to 237 (41%) of the 585 questions they pursued. The present study grouped the unanswered questions into 19 generic types. Three types accounted for 128 (54%) of the unanswered questions: (1) "Undiagnosed finding" questions asked about the management of abnormal clinical findings, such as symptoms, signs, and test results (What is the approach to finding X?); (2) "Conditional" questions contained qualifying conditions that were appended to otherwise simple questions (What is the management of X, given Y? where "given Y" is the qualifying condition that makes the question difficult.); and (3) "Compound" questions asked about the association between two highly specific elements (Can X cause Y?). The study identified strategies to improve clinical information retrieval, listed below.
To improve the chance of finding answers, physicians should change their search strategies by rephrasing their questions and searching more clinically oriented resources. Authors of clinical information resources should anticipate questions that may arise in practice, and clinical information systems should provide clearer and more explicit answers.
描述未得到解答的临床问题的特征,并提出可提高找到答案几率的干预措施。
在之前的一项研究中,研究人员在办公室观察初级保健医生,并记录患者护理过程中出现的问题。医生追查但仍未得到解答的问题被归为一般类型。在本研究中,研究人员试图回答这些问题,并制定旨在提高找到答案成功率的建议。
未得到解答的问题类型的频率以及提高找到答案几率的建议。
在早期研究中,48名医生在192次半天的办公室观察期间提出了1062个问题。在他们追查的585个问题中,医生未能找到答案的有237个(41%)。本研究将未得到解答的问题归为19种一般类型。其中三种类型占未得到解答问题的128个(54%):(1)“未确诊发现”问题,询问关于异常临床发现(如症状、体征和检查结果)的处理方法(如何找到X?);(2)“条件性”问题在其他简单问题后附加了限定条件(在Y的情况下,X的处理方法是什么?其中“在Y的情况下”是使问题变得困难的限定条件);(3)“复合”问题询问两个高度特定元素之间的关联(X会导致Y吗?)。该研究确定了改善临床信息检索的策略,如下所示。
为提高找到答案的几率,医生应通过重新表述问题并搜索更具临床导向性的资源来改变搜索策略。临床信息资源的作者应预测实践中可能出现的问题,临床信息系统应提供更清晰、更明确的答案。
