5.1 Prescribing:
- Registered medical practitioners of ST4 level and above, staff in a nonconsultant career grade and consultants, who are currently named on the register, can prescribe intrathecal chemotherapy.
- Chemotherapy must be prescribed on an NHS GG&C standardised preprinted or validated electronic intrathecal drug prescription chart. This chart must be completed legibly and be both signed and dated by the prescriber. Addressograph labels MUST be used on all copies of the prescription form.
- Dose variations are only permitted in line with detailed and authorised local or national protocols which are available within the unit.
- All prescriptions for intrathecal chemotherapy must be received by a chemotherapy competent pharmacist on the register before 3pm the day prior to the therapy being required. If prescriptions are not received prior to this time the procedure will require to be rescheduled.
- The intrathecal administration of chemotherapy must be scheduled to take place during the normal working day, ie between 10am and 5pm Monday to Friday. In the rare and exceptional clinical case where intrathecal chemotherapy is required out of hours or over a weekend or public holiday, the consultant in charge must make this request via the on-call pharmacist. No formal system is currently in place to allow this to happen, however, attempts will be made to contact the appropriate staff to try to facilitate this in life-threatening situations.
5.2 Preparation & Dispensing:
- All intrathecal prescriptions are screened and double-checked by chemotherapy-competent pharmacists named on the register to ensure an intrathecal chemotherapy preparation is indicated, the appropriate dose is prescribed and a doctor currently on the register has completed the prescription appropriately.
- Intrathecal chemotherapy is prepared in the pharmacy aseptic unit in the Royal Hospital for Children by trained pharmacy personnel named on the adult register and in accordance with all relevant procedures.
5.3 Labelling, Packaging & Storage in the Pharmacy:
- All intrathecal chemotherapy is labelled with the route of administration ‘FOR INTRATHECAL USE ONLY’ clearly displayed.
- All intrathecal chemotherapy is packaged individually inside a sealed, red cytotoxic bag clearly marked for INTRATHECAL PRODUCTS ONLY. The outside of the bag will be labelled with an individual patient label.
5.4 Issue of Drugs from Pharmacy:
- Intrathecal chemotherapy will be issued from the pharmacy aseptic unit at the Royal Hospital for Children. These will be issued individually with the appropriate prescription and as a separate item. The details on both the product and the prescription must be checked by the issuer and collector and the appropriate documentation completed. Intrathecal chemotherapy mustNEVERbe issued with chemotherapy for any other route. When a designated intrathecal theatre list is being performed, the intrathecal chemotherapy can be collected for all patients named on the theatre list, however, each patient’s treatment must be checked off separately as above.
- Intrathecal chemotherapy will only be issued to medical staff named on the register and this must be the individual who is administrating the intrathecal chemotherapy. For the purposes of training staff both the trainee and the supervisor must sign for the issue.
5.5 Timing of Issue from the Pharmacy:
- For outpatients only;if both intrathecal and intravenous bolus chemotherapy are scheduled on the same day, they must not be given at the same time or within the same designated patient area. Only when the pharmacy staff within the aseptic unit receive written confirmation that the intravenous drug(s) has been given, i.e. a copy of a signed prescription confirming the administration of the intravenous bolus dose, will the intrathecal drug(s) be released for that patient.
- Inpatientsmust be scheduled to receive all intravenous bolus chemotherapy and all intrathecal chemotherapy on different days.
- Intrathecal chemotherapy and any Vinca Alkaloid chemotherapy must be administered on the same day.
NB: Any out-patient having a bone marrow aspirate MUST be given any scheduled intravenous bolus chemotherapy prior to theatre. Inpatients MUST be scheduled to have intravenous bolus chemotherapy on a different day from the bone marrow aspirate.
5.6 Patient Review:
- An appropriately trained medical professional or advanced nurse practitioner must review the patient prior to the administration of intrathecal chemotherapy. They must ensure the patient is fit for treatment, correct investigations have been conducted and reviewed and the appropriate arrangements have been organised to allow the therapy to be administered.
- Consent must be obtained from parent/carer/patient (as appropriate) ensuring they are aware of the nature of the procedure, route of administration and the drug being given.
5.7 Administration of Drug(s):
- Patients must only receive intrathecal chemotherapy in designated areas where staff are routinely involved in the administration of drugs by the intrathecal route.
- Designated areas within the Royal Hospital for Children for intrathecal chemotherapy are:
- The ward treatment room in ward 2A(Schiehallion ward) – SCH-079
- Treatment Room 1 in the Ward 2B (Schiehallion Day Care Unit)
- Areas where general anaesthesia is being administered to the patient, i.e. theatre suite, MRI, PICU and interventional radiology.
- Intrathecal chemotherapy and intravenous bolus chemotherapy should never be administered at the same time or within the same designated area.
- Only a doctor at ST4 level or above, staff in a non-consultant grade and a consultant whose name appears on the intrathecal register, may administer intrathecal chemotherapy.
- For administration of intrathecal chemotherapy, the only syringes in the operating field of the patient are those containing intrathecal chemotherapy. Where local anaesthetic is given the administering syringes and needles must be removed from the field prior to the spinal needle being placed in the patient.
- Intravenous and/or subcutaneous infusions may be left in progress during the procedure. These must not be manipulated in any way while performing the lumbar puncture.
- Within paediatric practice many patients will receive intrathecal chemotherapy under general anaesthesia and, therefore, an exception must be made for drugs used to induce and maintain anaesthesia. Anaesthetists, however, must ensure all drug syringes are away from the sterile field prior to the administration of the intrathecal chemotherapy.
- Only a registered nurse, whose name appears on the intrathecal register, can check intrathecal drugs.
- Checking of intrathecal chemotherapy must be carried out as detailed in the “Safe & Secure Handling of Medicines in Hospital Ward, Theatres & Departments” policy.
- The intrathecal register must be available in all areas where intrathecal chemotherapy is administered.
- Any intrathecal cytotoxic drugs which are not administered to a patient must be discarded in a cytotoxic sharps box in the clean utility on Ward 6A or the clean utility room (shared with adults) on Ward 4B at QEUH; this must be documented and witnessed on the appropriate intrathecal prescription form which should then be returned to the Pharmacy Office near Ward 6A (POD 36).
- The aseptic unit must also document the destruction of any intrathecal products which are not collected and ensure a copy of this destruction is returned to the Pharmacy Office near Ward 6A (POD 36).
- The completed intrathecal chemotherapy prescription forms must be filed appropriately in the patient’s case records and subsequently scanned onto the patient’s electronic record.
