General Information Please note that this document is for use in Leeds Teaching Hospitals NHS Trust only. This document contains information on the most commonly used antibiotics, antifungals and antivirals at home but please contact us to discuss any drugs not featured.
Access
Peripheral cannulas
o The patient should be discharged with their cannula in situ
o Community nurses can cannulate patients
o Lloyds nurses are also able to cannulate patients
PICC (peripherally inserted central catheter) lines
o Inserted by OPAT nurse specialist or in theatres
o Should be flushed with 10ml of sodium chloride 0.9% before and after
a dose. Note that the community nursing team do not require a supply
of these flushes. These flushes will be supplied to the Lloyds nurses
via a Lloyds prescription, which the OPAT pharmacists will facilitate.
o A volumetric pump should be used to administer infusions as PICC
lines are prone to occlusions.
o May have one or two lumens
o If not being used for more than two days, PICC lines need each lumen
locking weekly with heparin 50 units in 5ml. An outpatient/Lloyds
prescription will be required to supply this.
o Required for continuous infusions, such as flucloxacillin, that are
administered over 24 hours. They can also be used for intermittent
infusions.
Midline
o Inserted by OPAT nurse specialist and medical staff above an FY1,
provided they have had training.
o Peripheral venous catheter
Patients may also have long term central lines in situ, such as Hickman lines.
Please refer to the Central Venous Catheter guidelines on Leeds Health
Pathways for more information.
Administration
Consider whether the medicine can be administered as a bolus or as an
infusion
Written by: Kelly Atack- Advanced Clinical Pharmacist for Infection & Travel Medicine Checked by: Pharmacy Infection Team Authorised by: IAPG Date: 20/12/19 Version 4

If the medicine requires administration as an infusion, consider the infusion
time as this may affect nursing visits and the number of patients we can
accept onto the service
Supply of Medicines on Discharge (for patients being discharged to Leeds OPAT)-
see flow chart on page 8
Community nursing team
o Require a supply of medicines via eDAN or Lloyds Homecare
o Supply a maximum of two weeks of intravenous antimicrobials on
discharge on an eDAN.
o Supply the full course of oral antimicrobials on an eDAN.
o Some antimicrobials such as flucloxacillin devices will require obtaining
from Lloyds. The OPAT pharmacist will facilitate this prescription but
the drug must be listed on the eDAN. The source must be assigned as
“DC-other”. Please comment in the pharmacy notes to GP section of
the eDAN ‘This patient has been discharged on a course of IV
antibiotics to be administered by the OPAT team. The infusion devices
have been supplied by Lloyds.’
o If an intravenous antimicrobial is supplied on an eDAN, then please
ensure a maximum of two weeks of diluents and fluids used for
reconstitution are supplied.
o Sodium chloride flushes do not need supplying.
Lloyds nursing team
o Require intravenous antimicrobials supplying via Lloyds prescriptions
o Intravenous antimicrobials must be listed on the eDAN. The source
must be assigned as “DC-other”. Please comment in the pharmacy
notes to GP section of the eDAN ‘This patient has been discharged on
a course of IV antibiotics to be administered by the OPAT team. The
infusion devices have been supplied by Lloyds.’
o Lloyds prescriptions will be facilitated by the OPAT pharmacist
o Any oral antimicrobials should be supplied as normal via the patient’s
eDAN.
o If validating a Lloyds prescription, please ensure the full course is
supplied, including sodium chloride 0.9% 10ml pre and post dose
flushes.
For any courses longer than two weeks, the supply of intravenous
antimicrobials, and diluents will be continued by the OPAT team via outpatient
prescriptions.

The Lloyds prescriptions require an ancilliaries and equipment list with the
medicine request. They also require a registration form if the patient has not
used the Lloyds service previously. This will be completed by the OPAT team.
Please note that delivery time for Lloyds prescriptions are approximately 48
hours but this may be longer over bank holidays and weekends.
Supply of Medicines on Discharge for patients being discharged to other OPAT
services outside of Leeds
Please contact each service to ask what they would like to be supplied. They
may require the full course of intravenous antibiotics and flushes.
Anaphylaxis
Please note that generally anaphylaxis kits are not provided to the community
nursing teams, as they carry adrenaline they can administer in an emergency.
The community nursing team can administer first doses of antimicrobials in a
patient’s home environment.
Nursing Capacity
We accept patients with three times daily dosing if we have capacity, so
please refer these patients to us
When the community nursing team is up to capacity, we can use the Lloyds
nursing service and have also trained patients and their carers to administer
intravenous medicines.
Note that both Lloyds and community nurses can go into, residential homes,
nursing homes and hospices.
If a patient is out of area, it is likely that an OPAT team will be in their area
that can provide a service. Contact our OPAT team for contact details of other
services
Some patients can also attend OPAT clinic, which is situated just outside of
J20 on level 9 of Gledhow wing.
Blood monitoring
The OPAT team review patient’s blood results including FBC, U&Es, LFT’s,
CRP and any therapeutic drug monitoring levels at least weekly at the virtual
OPAT ward round.
Note that community nurses can take bloods
Written by: Kelly Atack- Advanced Clinical Pharmacist for Infection & Travel Medicine Checked by: Pharmacy Infection Team Authorised by: IAPG Date: 20/12/19 Version 4
7
Lloyds nurses can also take bloods but require OrderComms requests, as
well as instructions on where to take the bloods when they have been taken.
The OPAT specialist nurse will facilitate this.
Storage of Medicines
Patients can store their intravenous antimicrobials that require refrigeration
storage in their own fridge, providing the medicines are placed on a shelf
away from food products and the temperature can be monitored.
Fridges can also be supplied by Lloyds.
Medicines requiring storage at room temperature should be kept out of reach
of children and pets. They should also be kept in a dry environment.

MHRA advice:
Disabling, long-lasting or potentially irreversible adverse reactions affecting musculoskeletal and nervous systems have been reported very rarely with fluoroquinolone antibiotics. Healthcare professionals are advised to inform patients to stop treatment at the first signs of a serious adverse reaction, such as tendinitis or tendon rupture, muscle pain, muscle weakness, joint pain, joint swelling, peripheral neuropathy, and CNS effects, and to contact their doctor immediately
There is a small increased risk of aortic aneurysm and dissection. Seek immediate medical attention if sudden-onset severe abdominal, chest, or back pain develops

Daptomycin
Indications
Used for the following infections when beta-lactams, glycopeptides, clindamycin and oral linezolid can’t be used because of intolerance, contraindications, treatment failure or antimicrobial resistance:
Skin and soft tissue infections in adults caused by Gram positive organisms
Right-sided infective endocarditis [RIE] due to Staphylococcus aureus.
Staphylococcus aureus bloodstream infection when associated with cSSTI
Infective endocarditis caused by susceptible Gram positive organisms [including left sided Staphylococcus aureus endocarditis].
Bloodstream infection caused by susceptible Gram positive organisms (except where the primary infection is pulmonary).
Dose
Dose Daily dose varies between 4 mg/kg and 6mg/kg ONCE DAILY depending on indication.
Dose in Renal Impairment Dosage adjustments are required in patients with a creatinine clearance of <30ml/min, including those receiving haemodialysis or CAPD. The recommended dosing interval for patients with a creatinine clearance of <30ml/min is every 48 hours. Haemodialysis patients should receive their dose after the dialysis session. The mg/kg dosing regimen should reflect the clinical indication.

Three times weekly dosing Patients can also be administered teicoplanin three times weekly. For this dosing, use the dosing guidance in the table above based on renal function, then multiply the daily dose by 7 and divide by 3 for the three times weekly dose. Note maximum of 2grams as a single dose. For example, a 50 year old male patient weighing 60kg with a creatinine of 200 (CrCl= 34mL/minute). Daily dose= 400mg OD. Three times weekly dose= 900mg three times weekly. NB Both doses rounded to the nearest 100mg for ease of administration.
