table 2 Benefits of adopting RTA gemcitabine Before After National standard doses • Local dose banding tables • 47 different doses dispensed • National standard doses • 13 different doses dispensed* Adoption of licensed RTA infusions • Unlicensed gemcitabine infusions purchased for high • Licensed infusions (10mg/ml) used where available – demand doses – shelf life of 84 days • In-house aseptic dispensing of less commonly used doses • 38mg/ml injection concentration used throughout • All infusions standard fill volume (250ml) shelf life of two years • In-house aseptic dispensing of less commonly used doses (100mg/ml injection) • Variable fill volumes depending whether licensed (10mg/ml) or in-house aseptic dispensing (250ml) • 60% of all doses dispensed as licensed infusions in last 12 months • Estimate will rise to 75% with arrival of 1400mg infusion • Released 2% of total aseptic items * Attributable to national standard doses rather than availability of RTA infusions Dose-dependent volumes were built into the drug catalogue and tested as shown in Figure 1. Benefits of adopting RTA gemcitabine infusions Table 2 summarises the local benefits of adopting RTA gemcitabine infusions. At present, there are licensed gemcitabine infusions on the market at the following doses: 1200mg; 1400mg (anticipated in 2018); 1600mg; 1800mg; 2000mg; and 2200mg. Conclusions Following initial efforts to manage the change in formulation(s) for gemcitabine infusions, the Trust is now able to offer licensed RTA infusions for the majority of patients receiving gemcitabine. Similar change management is applicable to other switches (for example, adoption of biosimilar antibody therapies). Use of a licensed infusion, where available, is in line with MHRA guidance and offers benefits to patients and health services through the use of a high-quality product with a long shelf life. Additionally, moving from specials releases aseptic capacity (both in-house and at commercial providers) to help meet the demand for other drugs/doses. Review of the volume of drugs/doses used following the adoption of national standard dosing might identify other products that are amenable to production as a licensed product. Key points • Where possible licensed medicines should be used. 6 • The use of licensed infusions releases aseptic capacity for other treatments. • e-Prescribing functionality enables dose-banding and dose-dependent infusion volumes to be automated, resulting in long-term benefits and no additional workload within busy clinics. • Longer shelf life reduces the likelihood of waste from last minute deferrals/dose changes. • With short-term work to manage transition, benefits can be realised in the long-term.
