To determine which resources residents use at the point-of-care (POC) for decision making, the drivers for selection of these resources, and how residents use Google/Google Scholar to answer clinical questions at the POC.
In January 2012, 299 residents from three internal medicine residencies were sent an electronic survey regarding resources used for POC decision making. Resource use frequency and factors influencing choice were determined using descriptive statistics. Binary logistic regression analysis was performed to determine relationships between the independent variables.
A total of 167 residents (56%) responded; similar numbers responded at each level of training. Residents most frequently reported using UpToDate and Google at the POC at least daily (85% and 63%, respectively), with speed and trust in the quality of information being the primary drivers of selection. Google, used by 68% of residents, was used primarily to locate Web sites and general information about diseases, whereas Google Scholar, used by 30% of residents, tended to be used for treatment and management decisions or locating a journal article.
The findings suggest that internal medicine residents use UpToDate most frequently, followed by consultation with faculty and the search engines Google and Google Scholar; speed, trust, and portability are the biggest drivers for resource selection; and time and information overload appear to be the biggest barriers to resources such as Ovid MEDLINE. Residents frequently used Google and may benefit from further training in information management skills.
确定住院医师在决策时在床边（POC）使用哪些资源，选择这些资源的驱动因素，以及住院医师如何使用 Google/Google Scholar 在 POC 回答临床问题。
2012 年 1 月，向来自三个内科住院医师培训项目的 299 名住院医师发送了一份关于在 POC 决策中使用资源的电子调查。使用描述性统计数据确定资源使用频率和选择的影响因素。使用二元逻辑回归分析确定自变量之间的关系。
共有 167 名住院医师（56%）做出了回应；每个培训水平的回应数量相似。住院医师最常报告在 POC 至少每天使用 UpToDate 和 Google（分别为 85%和 63%），选择的主要驱动因素是速度和对信息质量的信任。68%的住院医师使用 Google，主要用于查找网站和有关疾病的一般信息，而 30%的住院医师使用 Google Scholar，主要用于治疗和管理决策或查找期刊文章。
研究结果表明，内科住院医师最常使用 UpToDate，其次是与教员的咨询以及搜索引擎 Google 和 Google Scholar；速度、信任和便携性是资源选择的最大驱动因素；时间和信息过载似乎是像 Ovid MEDLINE 这样的资源的最大障碍。住院医师经常使用 Google，可能受益于进一步的信息管理技能培训。
