The foundation of EBGs rests on the principles of evidence-based medicine, which integrate individual clinical expertise with the best available external information provided by systematic research.15 All CHEST EBGs are designed to inform medical practitioners of the evidence-based state of knowledge developed from careful analysis of the most recent topical research. Today, medical information is available via the Internet to practitioners around the globe. Internet access is one measure of the global reach of CHEST EBGs. Since 2012, Internet access to AT95 has generated 1,178,368 HTML or PDF downloads. Since its publication in 2013, the CHEST lung cancer guideline4 has generated 194,419 downloads. The CHEST journal website has > 3 million visitors and web sessions annually, with 58% of this traffic coming from outside of the United States (Steve Welch, BA, Senior Vice President and Publisher, CHEST, personal communication, July 30, 2014). Medical practitioners worldwide access the CHEST website (Table 1). Because CHEST EBGs are available on an Internet platform and accessible to any practitioner with Internet access, CHEST EBGs extend to all corners of the world. Access and use data demonstrate extensive worldwide access of CHEST EBGs, suggesting that they are global.
