Working sterile on location: the protocol behind the treatment
In brief
Working outside a clinic does not call for less protocol, but for more preparation. Four things determine whether it is justified: a suitable space assessed in advance, an unbroken cold chain for the product, a sterile working field with single-use materials, and watertight recording of batch numbers and procedures. This article is written for fellow doctors and for partners who want to know what happens at their venue.
The space
The requirements are not exotic, but they are firm. A separate room or corner where nobody walks through during the treatment. A work surface that can be cleaned and disinfected, so no fabric or rough wood. A washbasin with running water, soap and single-use towels. Sufficient, even lighting: shadows are the enemy of accurate placement.
What does not belong: pets in the room, draught from an open door, and treating during a cleaning round. We assess every location in advance and record our findings. If a space does not meet the requirements, the answer is no, however keen the partner may be.
The cold chain
The product must be kept refrigerated and that chain may not be broken. In practice that means transport in a validated cool box with temperature logging, and taking no more than is needed for that day.
Temperature logging is not a formality. If there is any doubt about the chain, the product is not used, full stop. A wasted vial is cheaper than a treatment with a product whose potency you cannot guarantee.
The sterile field
- Hand disinfection according to protocol, followed by non-sterile examination gloves for this indication.
- Skin disinfection of the treatment area with sufficient contact time, even when that feels long.
- Single-use needles and syringes, opened from sealed packaging in the patient's presence.
- Dilution and drawing-up carried out on a clean, separate field, not alongside used materials.
- No reuse of a punctured vial between patients without recorded storage conditions and post-puncture shelf life.
Sharps waste and materials
Sharps go into an approved container that the doctor brings and disposes of personally. Leaving this behind with a partner is not acceptable; they have no contract for medical waste and may not put it in commercial waste.
The remaining used materials go back as well. The partner finds the room as they provided it.
Record keeping
For each treatment the following are recorded: date and location, the treating doctor, the product with batch number and expiry date, the areas treated and the dose per area, the aftercare instructions given, and anything noteworthy.
This record is not only a legal obligation, it also makes a recall possible. If a batch turns out to be problematic, you want to know within the hour who received it.
Emergencies
Emergency medication is present at every location and the route to the nearest hospital is known. The doctor knows the protocol by heart, because a protocol you have to look up is too slow.
Practical matters too: a phone with reception, a second person on the premises, and a clear agreement with the partner about what happens if a treatment overruns or has to be stopped.
Frequently asked questions
Is treating outside a clinic permitted?
Yes, provided the practitioner is authorised and competent and the circumstances are sound. The law sets requirements for who treats and how, not for the type of room.
Who is responsible for hygiene at a partner location?
The treating doctor. The partner provides a space; the assessment, the materials, the protocol and the disposal of medical waste all rest with the doctor.
What happens to the sharps waste?
It goes into an approved container that the doctor takes away and has disposed of through a contracted processor. It is never left behind with the partner.
