The cognitive impact of research synopses on physicians: a prospective observational analysis of evidence-based summaries sent by email

Abstract

Background Effective information transfer in primary care is becoming more difficult as the volume of medical information expands. Emailed research synopses are expected to raise awareness and thereby permit more effective information retrieval. Objective To identify key factors that influence physicians' self-reported cognitive impact of emailed research synopses. Method In this prospective observational study, research synopses sent by email between 8 September 2006 and 30 May 2007 were analysed. Seven characteristics of synopses (number of characters, research design, study setting, number of types of patient populations studied, number of comparisons, number of outcomes, and number of results) were analysed. Each synopsis was classified as either positive or negative based on physician-reported impacts. Logistic regression analysis was used to evaluate the association between a negative impact and the synopsis' characteristics. Results A total of 1960 Canadian physicians submitted 159 442 ratings on 193 synopses. Each

Decision boxes for clinicians to support evidence-based practice and shared decision making: the user experience

“…Brevity and lower density of information are especially critical to foster a positive first impression of such tools [22,23], and to improve users’ comprehension of the options [24]. Other factors are also at play during the first contact between the receiver and the message, such as the credibility of the source of information (expertise, trustworthiness) [25].…”

Printed educational materials: effects on professional practice and healthcare outcomes

“…For format, we considered format, appearance, and length. Shorter and simpler documents have the potential to facilitate more e ective and e icient uptake of key information, as professionals o en do not have time to screen, organise, and appraise new scientific literature (Grandage 2002; Marriott 2000; Wang 2009).…”

In this issue of Informatics in Primary Care: ethnicity, learning and diabetes

“…The first by Wang et al, looks at the characteristics of brief synopses of evidence sent by email. 6 Physicians gave the highest ratings to the more complex synopses, which had more results, and more comparisons. Perhaps suggesting that clinicians like detail in order to appraise evidence rather than evidence-based bullet points!…”
