Table 6. Indicators associated with streamlining of antimicrobial therapy: antimicrobial stewardship teams with and without a dedicated ID pharmacist.
| Appropriate streamlining of therapy (%)a | |||
| ID Pharmacist Hospital | Geographic Model Hospital | P* | |
| Discontinuation of therapy when determined not bacterial | 37/48 (77.1%) | 11/33 (33.3%) | .0002 |
| Therapy modification indicated based on laboratory data | 143/190 (75.2%) | 51/100 (51%) | <.0001 |
| Therapy modification within 24 hours of laboratory data | 124/143 (86.7%) | 37/51 (72.6%) | .029 |
| IV to PO conversion completed when appropriate | 97/120 (80.8%) | 41/67 (61.2%) | .0052 |
| All of the above streamlining activities | 165/182 (90.7%) | 47/95 (49.5%) | <.0001 |
| ID consult | 41/43 (95.3%) | 11/25 (44%) | <.0001 |
| No ID consult | 124/139 (89.2%) | 36/70 (51.4%) | <.0001 |
Note: The ID Pharmacist Hospital has an antimicrobial stewardship program staffed by a full-time ID pharmacist. At the Geographic Model Hospital, ward pharmacists provide support for antimicrobial stewardship. Differences in categorical variables were assessed using chi-square analysis. IV = intravenous; PO = oral.
Denominator denotes number of antibiotic courses where specified streamlining was indicated.
P < .05 was considered significant.
