Why was it done?
Daptomycin is an intravenous antibiotic usually prepared in Hospital Pharmacy services. Normally it is dosed based on body weight, which requires each intravenous mixture to be prepared in an individual manner for each patient. This might lead to an increased assistance workload in elaboration areas, a higher number of errors in the preparation and high costs due to waste materials generated during preparation.
What was done?
The aim of this study is to describe the preparation of intravenous daptomycin by dose banding, a system in which daptomycin doses are rounded up or down in order to standardize and protocolize the preparation of intravenous mixtures as much as possible.
How was it done?
In order to improve this situation, dose banding strategy was implemented in February 2019: the obtained final dose was rounded in such a way that only mixtures of 500, 700 and 850 mg were prepared (in agreement with Hospital Pharmacy and Infectious and Microbiology medical teams) , following this scheme:
PRESCRIBED DOSE PREPARED DOSE
< 400 mg Prescribed dose (individualized)
400–599 mg 500 mg
≥600–799 mg 700 mg
≥800 mg 850 mg
What has been achieved?
Previous year before starting dose banding strategy (2018), 5493 individualized doses of daptomycin were prepared for 437 patients in our Pharmacy service. Between June 2020 and June 2021, 2680, 2555 and 997 units of daptomycin 500, 700 and 850 mg, respectively, were prepared for 360 patients. Batches of standardized doses were prepared in advance and kept refrigerated (stability of 10 days in 100 ml of physiological saline) until dispensation. In addition, during the same period, 15 patients (4 from pediatrics) received 209 individualized doses (3.2% of the total doses) due to their low body weight.
What next?
This strategy might decrease the number of errors in preparation and reduce processing times, which is essential since early appropriate antibiotic treatment in severe infection has been associated with better outcomes. Dose banding model could be extrapolated to other drugs with good physical, medical and microbiological stability in dilution, which are frequently prescribed and when few dose bands can cover most of the prescriptions.
