BackgroundDose banding (DB) (dose rounding with predetermined variation with prescription) enables in-advance preparation of high-turnover anticancer drugs with potential benefit for pharmacy compounding work flow.ObjectivesTo analyse the impact of potential situations on the efficiency of DB in the pharmacy (safe and maximum storage), calculate preparation lead times and the potential full-time equivalent (FTE) benefit.MethodsCandidate intravenous anticancer drugs were selected for logarithmic DB according to prescribing frequency, infusion volume and stability (usage data 2015 of the tertiary Ghent University Hospital, Belgium). With a selected DB set already stored, a 2-week time study (April/November 2015) provided lead times (between prescription and transfer) for just-in-time and DB preparations. A ‘maximal’ storage (using all drugs with a relative incidence of ≥2% recurrent monthly prescription) and a ‘safe’ storage scenario (lowest monthly prescribing pattern) were used to calculate the potential future FTE change.ResultsMean lead times for DB storage and just-in-time preparation were 17.1 min (95% CI 13.5 to 21.0) and 26.5 min (23.3 to 29.8). For 21 164 yearly preparations with already 5292 in DB (25%), 11 157 and 6 862 could be batch-produced in advance in a maximum storage and safe storage scenario, respectively. The existing FTE in 2015 of 5.41 could then be reduced to 4.91 and 5.27.ConclusionFurther development of DB could contribute to pharmacy compounding efficiency.

Introduction Extravasation by conventional cytotoxics has been well documented. While monoclonal antibodies are not considered to have the necrotic potential of some cytotoxic medicines, they require appropriate management in case of extravasation. However, fewer data are available on their classification and appropriate management when extravasation occurs. As monoclonal antibodies are being more commonly used in current daily oncology practice, this is an issue that cannot be ignored. Methods A scientific literature review on PubMed was conducted. All findings were critically appraised independently by 6 clinical pharmacists in order to provide a classification according to the extravasation hazard. Results A classification of non-conjugated and conjugated monoclonal antibodies according to extravasation hazard has been elaborated for different molecules frequently used in oncology. In addition, general management, in case extravasation of monoclonal antibodies occurs, has been proposed and the role of the pharmacist in the extravasation process has been described. Conclusion A classification of hazard extent of extravasation of monoclonal antibodies with concurrent management based on literature data and expert consensus has been elaborated. In addition, the role of the oncology pharmacist is crucial in terms of follow-up and documentation of the extravasated monoclonal antibody and management is described.
