Outpatient parenteral antibiotic therapy
| Outpatient parenteral antibiotic therapy | |
|---|---|
| Other names | OPAT |
Outpatient parenteral antibiotic therapy (OPAT) is used to administer non-oral antibiotics (usually intravenously) without a need for ongoing hospitalisation. OPAT is particularly useful in people who are not severely unwell but do require a prolonged course of treatment that cannot be given in oral form.[1] OPAT is being increasingly adopted as part of antimicrobial stewardship programs, it can reduce length of stay, costs and adverse events while improving quality of life.[2] OPAT can be administered in Day Hospital or as part of home assistance care using elastomeric pumps.
Common antimicrobials
Common antimicrobials used for continuous infusion are shown below:[3]
| Antibiotic | Stability at 25 °C | Diluent | Existing data in elastomeric pumps |
|---|---|---|---|
| cefepime | 24 hours | normal saline | Yes |
| ceftazidime | 48 hours | normal saline | Yes |
| clindamycin | 16 days | dextrose 5% | No |
| flucloxacillin | 24 hours | normal saline | Yes |
| fosfomycin | 24 hours | water for injection | No |
| oxacillin | 24 hours | normal saline | No |
| benzylpenicillin potassium | 24–48 hours | ringer acetate | Yes |
| benzylpenicillin sodium | 12–24 hours | normal saline | Yes |
| piperacillin/tazobactam | 24 hours | normal saline | Yes |
| vancomycin | 7 days | normal saline | Yes |
Before starting beta-lactams and vancomycin infusion, it is advisable to administer a loading dose in order to reduce time to reach target concentrations[4][5]
