OPAT (Outpatient Parenteral Antimicrobial Therapy) is a safe and convenient way to receive intravenous (IV) antibiotic therapy at home or in a clinic. With your permission, your doctor may refer you to the OPAT team. The team will look after your IV antibiotic treatment when you are discharged from hospital.

Sometimes the best or only way to treat certain infections is to give antibiotics intravenously. However, you may not always need to remain in hospital for this treatment. Intravenous antibiotics may be required for a few days or weeks. Your doctor or nurse will explain why IV antibiotic treatment may beneficial.

A vascular access device is a thin, flexible, plastic tube that is placed into the vein using a small needle. This will be needed in order for the IV antibiotic to be administered into the vein. The type of vascular access device that you may need will depend on a combination of factors. These include the number of days that IV treatment may be needed, the type of IV antibiotics needed and the health of your veins.

The OPAT Clinical Nurse Specialist and a doctor who specialises in infections will meet with you to assess your health problems. The option of having IV antibiotic therapy at home or at the OPAT clinic will be discussed with you. They will ask questions about your health, about your lifestyle, where you live and who is around to help at home. The team will then decide if antibiotics can be provided for you safely whilst you are at home.

There are a number of ways that the OPAT service can facilitate IV antibiotic therapy in the community. The OPAT team will discuss the options available to you. 

The OPAT team will need to monitor you carefully when you leave hospital. You will need to regularly attend follow up appointments at the Mortimer Market OPAT clinic - usually once each week. During your visit to the clinic, you will see a specialist nurse and infection doctor.

During your IV antibiotic treatment at home or at the OPAT clinic, it is important that you contact the OPAT team in the event of any issues. This may be if you are unwell, have problems with the antibiotics prescribed for you or with the vascular access device that was inserted at the hospital. Please refer to the ‘Traffic Light Action Card’ for guidance.

Contact details for the OPAT team are noted on the back of this leaflet.

If you require patient transport to attend your outpatient appointment, please contact the transport assessment team no later than 3:30pm the day before your appointment – the telephone number can be found on the back page of this leaflet.
