TABLE 2.
Frequencies of amoxicillin-clavulanate (AMC)-resistant E. coli isolates by wards
| Ward | No. (%) of AMC-resistant E. coli isolates
|
||
|---|---|---|---|
| 1996 | 1997 | 1998 | |
| Intensive-care units | 8 (6.0) | 7 (6.5) | 8 (6.7) |
| Surgery | 24 (9.0) | 13 (5.5) | 19 (7.8)b |
| Medicine | 27 (4.5) | 40 (7.0)a | 16 (2.8)ab |
| Geriatrics | 9 (7.3) | 6 (5.0) | 10 (7.0) |
a
Significant decrease between the frequencies of AMC-resistant E. coli in 1998 and 1997 in medical wards (P = 0.008).
b
Frequency of AMC-resistant E. coli was significantly lower in medical wards than in surgical wards in 1998 (P = 0.001).
