BACKGROUND Electronic medical knowledge resources are frequently used for clinical decision support. Costs vary substantially among vendors, warranting periodic assessment of institution-wide adoption. OBJECTIVE To compare two medical knowledge resources, UpToDate and DynaMed Plus, with respect to facilitating accuracy and efficiency of answering standardized clinical questions and user experience. METHODS Physicians in training at a single academic medical center were randomized to first use one of the two medical knowledge resources to answer six standardized clinical case questions. They were surveyed about their experience using the resource, then completed the questions using the other resource, followed by the user experience survey again. The percentage of accurate answers and time required to answer each question were recorded. The surveys assessed ease of use, enjoyment using the resource, quality of information, and ability to assess the level of evidence. Given the cross-over design, tests of carry-over effects were performed. For open-ended survey items regarding overall user experience, themes were identified, and sentiment analyses were performed. RESULTS Twenty-six physicians in training participated, with a mean (standard deviation, SD) of 5.8 (2.5) years of prior experience using UpToDate. Accuracy of answers when using the two resources generally differed by 4 percentage points or less. For all but one question, there were no significant differences in the time required for completion. Most participants perceived both resources to be easy to use, have high quality of information, and felt able to assess to the level of evidence contained in the information. A greater proportion of participants (23/26, 88%) endorsed enjoyment of use when using UpToDate compared to when using DynaMed Plus (16/26, 62%). Participants were significantly less likely to enjoy DynaMed Plus if they were in the randomization group assigned to use UpToDate first (p=0.006). Themes emerging from open-ended survey comments included interface/information presentation, coverage of clinical topics, search functions, and utility for clinical decision-making. Overall, the majority (59%) of open-ended comments expressed an overall preference for UpToDate, while only 19% expressed an overall preference for DynaMed Plus. CONCLUSIONS DynaMed Plus is non-inferior to UpToDate with respect to ability to achieve accurate answers, time required for answering clinical questions, ease of use, quality of information, and ability to asses level of evidence. However, user experience was more positive with UpToDate, leading to a majority of users stating a preference for UpToDate. Future studies of electronic medical knowledge resources should continue to emphasize evaluation of usability and user experience.

Objective – This project sought to identify the five most used evidence based bedside information tools used in Canadian health libraries, to examine librarians’ attitudes towards these tools, and to test the comprehensiveness of the tools. Methods – The author developed a definition of evidence based bedside information tools and a list of resources that fit this definition. Participants were respondents to a survey distributed via the CANMEDLIB electronic mail list. The survey sought to identify information from library staff regarding the most frequently used evidence based bedside information tools. Clinical questions were used to measure the comprehensiveness of each resource and the levels of evidence they provided to each question. Results – Survey respondents reported that the five most used evidence based bedside information tools in their libraries were UpToDate, BMJ Clinical Evidence, First Consult, Bandolier and ACP Pier. Librarians were generally satisfied with the ease of use, efficiency and informative nature of these resources. The resource assessment determined that not all of these tools are comprehensive in terms of their ability to answer clinical questions or with regard to the inclusion of levels of evidence. UpToDate was able to provide information for the greatest number of clinical questions, but it provided a level of evidence only seven percent of the time. ACP Pier was able to provide information on only 50% of the clinical questions, but it provided levels of evidence for all of these. Conclusion – UpToDate and BMJ Clinical Evidence were both rated as easy to use and informative. However, neither product generally includes levels of evidence, so it would be prudent for the practitioner to critically appraise information from these sources before using it in a patient care setting. ACP Pier eliminates the critical appraisal stage, thus reducing the time it takes to go from forming a clinical question to implementing the answer, but survey respondents did not rate it as high in terms of usability. There remains a need for user-friendly, comprehensive resources that provide evidence summaries relying on levels of evidence to support their conclusions.

Abstract Background The Internet is increasingly used as a source of information. This study investigates with a multidimensional methodology the quality of information of websites dedicated to obesity treatment and weight-loss interventions. We compared websites in English, a language that it is used for the international scientific divulgation, and in Italian, a popular local language. Methods Level of Evidence: Level I, systematic review search on four largely used search engines. Duplicated and unrelated websites were excluded. We checked: popularity with PageRank; technological quality with Nibbler; readability with the Flesch Reading Ease test or the Gulpease readability index; quality of information with the DISCERN scale, the JAMA benchmark criteria, and the adherence to the Health on the Net Code. Results 63 Italian websites and 41 English websites were evaluated. English websites invested more in the technological quality especially for the marketing, experience of the user, and mobile accessibility. Both the Italian and English websites were of poor quality and readability. Conclusions These results can inform guidelines for the improvement of health information and help Internet users to achieve a higher level of information. Users must find benefits of treatment, support to the shared decision-making, the sources used, the medical editor's supervision, and the risk of postponing the treatment.
