The feasibility of implementation and the validity of these surveillance definitions would benefit from further assessment in different types of LTCFs. As with the original article by McGeer and colleagues, 1 these definitions have not been tested in advance of their publication. Data from a French study demonstrated that application of the original surveillance definitions underestimated the number of nursing home–associated infections when compared with provider diagnoses of infection. 9 This finding highlights the need for future studies to determine the sensitivity and specificity of criteria used within the surveillance definitions and to validate their application in this setting.
You may want to identify certain types of equipment by vendor name and brand or category (., ultracentrifuge vs. prep centrifuge), particularly if they are not commonly found in most labs. It is appropriate to report, parenthetically, the source (vendor) and catalog number for reagents used, ., " ....poly-L-lysine (Sigma #1309) ." When using a method described in another published source, you can save time and words by providing the relevant citation to the source. Always make sure to describe any modifications you have made of a standard or published method.
