Why was it done?

Romiplostim should be administered once weekly as a subcutaneous injection. The initial dose is 1µg/kg. According to platelet response (PR) the dose should be increased until the patient achieves platelet count over 50,000 platelets/µL(maximum dose=10µg/kg). In order to maintain durable PR, weekly doses of romiplostim are prescribed and adjusted every 4-6weeks. Although patients could be trained for the injection preparation, many had reported difficulties to understand instructions and calculations of concentrations/volume. Romiplostim vials have a significant overdose to ensure the extraction of the declared amount. The actual content of the 250µg vial was found to be 360 µg (110µg excess). The 500µg vial contents 600µg. In addition, patients should discard the unused part. The aim is to centralise the preparation/distribution of individualised weekly doses of romiplostim for each patient in RtA syringes that allows them to receive the correct dose and to maximise the use of vials.

What was done?

We develop a procedure for the preparation and distribution of individualised weekly doses of romiplostim prepared in the sterile preparation area in prefilled syringes Ready to Administer (RtA) by the patient.

How was it done?

The Pharmacy service (PS) prepares the individualised doses in syringes RtA in a laminar-flow cabinet. The waste of the vial is kept to be reused.
The main obstacle is the increase in the volume of daily preparations in the PS due to dose individualisation. This obstacle is overcome with fluid communication with the Haematology service that reports prescriptions with a duration of up to 21 days (if the patient´s control is adequate).

What has been achieved?

From the past 3 years (2019-2021), we prepared individualised syringes for 36 patients. The centralised preparation reduces unused romiplostin waste allowing a cost saving of near 50% of drug spending. Specifically, in this 3-year period, €385,759.00 were saved.

What next?

Preparation of RtA syringes of romiplostim under sterile conditions in a laminar-flow cabinet helps patient’s auto-administration (since is an easier dispositive) and allows for greater use and significant economic savings. It is a process that can be easily extrapolated to any PS. Next step would be to carry out stability studies in order to be able to work further in advance and allow to space out hospital visits of well-controlled patients.

Why was it done?

To improve safety during preparation and administration of IAD.

What was done?

A new computerized system was established to improve quality control and traceability in preparation and administration of intravenous antineoplastic drug (IAD).

How was it done?

The software currently in use was updated, checking densities of IAD, weights of diluents and consumables. Protocols in pharmacology were adapted and maximum permissible error rates during elaboration were established. The Aseptics Pharmacy Department was equipped with a barcode label printer (BLP), a barcode scanner (BS), a precision scale and an All In One computer for the biological safety cabinet (BSC). The Haematology and Oncology Day Treatment Unit (DTU) was equipped with a BLP (for hospital bracelets) and portable computers with BS.
Regarding elaboration, a qualitative control was performed in the BSC by scanning data matrix or barcodes, recording batches and expiration dates, both of the diluent and antineoplastic agents. A quantitative gravimetric test was also performed using weight measurement of the diluent and devices before and after adding the drug. When the mixture was correctly prepared a label was printed with an identifying barcode.
Administration of the right bag to the right patient was also ensured by scanning barcodes in DTU: A hospital bracelet with a barcode was printed to identify each patient at their arrival to DTU. Prior to administration, double scan confirmation was made, checking patient´s bracelet and treatment (label), by using BS, ensuring that each patient received the drug, at the right dose, on time and by the correct route of administration.

What has been achieved?

All intravenous cancer therapies have been administered with double scan confirmation in DTU since the new system was established (November 2019).
This new way of processing IAD has been completely installed, but not all the antineoplastic treatments have been prepared with quality control.
The whole process has also left a complete computer record of the staff, task performed, time, duration and potential incidents.

What next?

We will gradually implement quality control while processing all intravenous antineoplastic treatments.

The introduction of an emergency intravenous antibiotic reconstitution service during the COVID-19 pandemic.

Why was it done?

There was concern that there was a risk of reconstitution errors, missed doses or variation in dosing intervals which could impact on treatment efficacy and patient safety due to:
• a sudden increase in demand for IV antibiotics,
• depleted numbers of front-line nursing staff, and
• nurses being deployed to unfamiliar clinical environments and encumbered by PPE.
The emergency IV antibiotic reconstitution service was designed to mitigate these risks.

What was done?

In the absence of aseptic dispensing facilities an emergency intravenous (IV) antibiotic reconstitution service was set up in a laminar flow operating theatre. Nurses who could not work in a patient-facing role during the pandemic prepared ready-to-use infusions under the direct supervision of a pharmacist.

How was it done?

It was determined that a manufacturer’s licence was not required under part one, section three of the Human Medicines Regulations 2012 providing strict criteria were adhered to. Stability data was collated for the most frequently used IV antibiotics. Even where stability data supported a longer period, a maximum expiry of 24 hours after preparation was assigned. Processes were designed to adhere as closely as possible to the GMP principles described within The Rules and Guidance for Pharmaceutical Manufacturers and Distributors 2017. Specially tailored IV reconstitution training was delivered to the nurses.

What has been achieved?

Over a period of 4 weeks at the peak of the pandemic 1000 doses of IV antibiotics were prepared and supplied, enabling ward-based nurses to focus directly on patients. There were no reports of any incidents of delayed or missed doses, or administration errors relating to IV antibiotics supplied to the wards involved during this period. The time saved on the wards was equivalent to having 3 additional nurses on the wards each day.

What next?

With a reduction in the number of COVID-19 positive patients now presenting to the hospital the service has been paused but placed on standby so that it can be resumed in the event of a second wave. Work is underway to determine if there would be value in the team preparing a wider range of products, particularly those which may be of particular use in critical care areas such as sedatives and inotropes.

Why was it done?

Aim of the study was to evaluate if the microbiological cleanliness of the working area of APOTECAchemo® is affected by extending the interval of intensive cleaning from biweekly to monthly cleaning intervals.

What was done?

Automated preparation of ready-to-administer chemotherapy products with the APOTECAchemo® robot is well established in a number of pharmacy departments. One of the few disadvantages is the time-consuming, intensive cleaning and disinfection of the working area (clean room class A) by wiping with cleaning and disinfection solutions.

How was it done?

Every two weeks (period 1: 07-12/2018) or every four weeks (period 2: 01-06/2019) all surfaces in the working area of APOTECAchemo® were wiped with ethanolic NaOH solution in order to inactivate or remove cytotoxic spillages. In a second work step all surfaces are disinfected by wiping with spore-free alcohol. The procedure lasts about one hour. The working area is at the end of each working session irradiated with UV light for 4 hours. Microbiological monitoring of the working area is done weekly in operation by passive air sampling (2 settle plates at predefined locations S1, S2) and surface sampling (3 contact plates at predefined locations O1, O2, O3) and colony-forming units (CFU) are counted after incubation. Results of the microbiological samples (CFU ± standard deviation) were compared for period 1 and 2. On average, 0 CFU (n=52) were detected (period 1) and 0.04±0.2 CFU (n=44) (period 2) on settle plates. During period 1 on average 0.04±0.19 CFU were found at O1, 0 CFU on O2, and 0.81 CFU±4.23 at O3 (n=27 each). During period 2, 0 CFU were detected at O1, O2 and 0.04±0.2 CFU at O3 (n=25 each). The extended interval for the intensive cleaning process did not affect the microbiological cleanliness. The CFU limits set for clean room class A were met.

What has been achieved?

Maintaining the daily cleaning procedure, the interval of intensive cleaning can be extended to one month without increasing the microbiological contamination risk and saving two hours of cleaning.

What next?

Monthly intensive cleaning will be attended by trending the microbiological results.
