Seven CPG were selected, written by institutions and official bodies that have assessed the best scientific evidence available to prevent SSI in the 3 phases of surgical treatment.

There is a certain disparity between the level of evidence and the recommendation grade, as in the case of normothermia, where some CPG recommend maintaining very demanding temperature levels between 36<span class="elsevierStyleHsp" style=""></span>°C and 38<span class="elsevierStyleHsp" style=""></span>°C (CPSI) and other indications are more lax at >35.5<span class="elsevierStyleHsp" style=""></span>°C (SHEA). Likewise, it is not clear if the application of these measures must be carried out in the perioperative phase or only in the intraoperative period. With glycemia, the situation is similar, since it is not clear if the maximum level of glycemia allowed (180 vs 200<span class="elsevierStyleHsp" style=""></span>mg/dL) should be applied only to diabetic patients, if it should be met in the 3 phases and if it would be indicated according to the type of intervention.</p><p id="par0125" class="elsevierStylePara elsevierViewall">Furthermore, when comparing different CPG, we observed that only 4 measures were recommended by all guidelines and institutions: appropriate elimination of hair, antibiotic prophylaxis, preparation of the surgical field with an alcohol-based product (most CPG recommend alcoholic chlorhexidine [AC]) and normothermia. Other measures, however, such as the screening of <span class="elsevierStyleItalic">S. aureus</span> and preoperative showering with soap, are recommended in few CPG.<a class="elsevierStyleCrossRefs" href="#bib0285"><span class="elsevierStyleSup">5,8,21–23,25–27</span></a> In addition, the majority coincided in not recommending measures such as plastic incise drapes<a class="elsevierStyleCrossRefs" href="#bib0285"><span class="elsevierStyleSup">5,8,21–23</span></a> or antimicrobial agents in sutures.<a class="elsevierStyleCrossRefs" href="#bib0300"><span class="elsevierStyleSup">8,25</span></a> Specifically, the latter is recommended in only one set of guidelines, although with very limited evidence,<a class="elsevierStyleCrossRef" href="#bib0395"><span class="elsevierStyleSup">27</span></a> whereas screening for <span class="elsevierStyleItalic">S. aureus</span>, for example, remains a controversial practice. Some guidelines recommend screening for methicillin-resistant <span class="elsevierStyleItalic">S. aureus</span> (MRSA),<a class="elsevierStyleCrossRef" href="#bib0390"><span class="elsevierStyleSup">26</span></a> while others simply recommend screening for <span class="elsevierStyleItalic">S. aureus</span>,<a class="elsevierStyleCrossRef" href="#bib0385"><span class="elsevierStyleSup">25</span></a> and others do not even recommend screening due to lack of evidence.<a class="elsevierStyleCrossRef" href="#bib0365"><span class="elsevierStyleSup">21</span></a></p><p id="par0130" class="elsevierStylePara elsevierViewall">Although there is unanimity in recommending the 4 mentioned preventive measures, slight variations are given in the specific recommendations and in the critical points that specify these recommendations, such as dosages of the antibiotic as prophylaxis or administration prior to the incision. The same occurs with the type of antiseptic applicator for the preparation of the skin, whereas other key issues are not discussed, such as the friction technique or the number of times the product should be applied. While to date no systematic reviews have been published on the effectiveness of normothermia and normoglycemia, the CPG coincide in recommending them.
