Sensitivity of the IDI-MRSA-based screening strategy to detect MRSA-colonized patients
| Swab source(s) | No. of positive swabs detected/no. of true-positive swabsb | % Sensitivity |
|---|---|---|
| Nares | 54/71 | 76 |
| Rectum | 54/71 | 76 |
| Othera | 10/18 | 56 |
| Nares and rectum | 67/70c | 96 |
| Nares, rectum, and other | 72/72 | 100 |
a
Other sources included open wounds and line exit sites.
b
The number of positive swabs detected is the number of samples from the site(s) specified detected as positive for MRSA by IDI-MRSA. True-positive specimens were defined as those determined to be positive by culture or those corresponding to specimens from other sites collected on the same day and found to be positive by culture.
c
Only swabs from patients who had both rectal and nasal sites tested are included.
