Footnotes for Table 5:
- SSIs included are those following select surgical procedures approximating procedures covered by SCIP, using only SSIs that were classified as deep incisional or organ/space, and detected upon admission or readmission. Specific NHSN procedures are listed in Appendix A.
- Continuous reporters for CLABSI include all facilities that reported any data from at least one location during both 2009 and 2010. Continuous reporters for SSI include all facilities that reported any data for any of the 10 SCIP procedures during both 2009 and 2010.
- Adjusted by limiting analysis to only continuous reporters, i.e., facility locations reporting for 1 month or more during 2009 that also reported during 2010.
- Coronary artery bypass graft includes procedures with either chest only or chest and donor site incisions.
