Intravenous Antimicrobial Therapy (OPAT)
What Is OPAT?
OPAT allows patients with serious or complex infections to receive IV antibiotics without prolonged hospital stays. Medications are administered at home, in an infusion center, or sometimes in the clinic, depending on your needs.
Conditions commonly treated with OPAT include
- Bone & joint infections
- Bloodstream infections
- Endocarditis (heart valve infection)
- Complicated urinary tract infections
- Skin & soft tissue infections
- Post-surgical or device-related infections
Benefits of OPAT include:
- Faster return to home and daily activities
- Reduced hospital costs and exposure
- Close specialist follow-up to ensure safety and effectiveness
Early Treatment
Why Specialist Oversight Matters
IV antibiotics can be powerful but carry risks, including allergic reactions, line infections, or antibiotic resistance. Without proper monitoring, complications may arise.
At Infinity ID, OPAT is directly overseen by a board-certified Colorado Infectious Disease physician, ensuring:
- The right antibiotic for the right infection
- Safe line placement and care (PICC line or other access)
- Regular lab monitoring to check response and side effects
- Adjustments to therapy as needed for optimal recovery
