Objectives:
This study aimed to investigate factors associated with daptomycin consumption in French healthcare facilities (HCF) between 2019 and 2020.
Methods:
Antibiotic consumption expressed as number of defined daily doses (DDD) per 1,000 patient-days (PD) and antimicrobial resistance (AMR) expressed as incidence densities per 1,000PD were extracted each year from the nationwide surveillance network run by the SPARES project (Surveillance and Prevention of Antimicrobial RESistance in hospitals), collecting data at ward level among voluntary HCFs using standardized methodology and webtool. All HCF participating both in 2019 and 2020 were included. A multivariable linear regression was fitted.
Results:
Among 622 HCFs, we analyzed daptomycin consumption and AMR data in 1,637 clinical wards. Incidence densities of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative staphylococci (MRCNS) were the highest in intensive care unit wards (0.54 and 6.83 respectively in 2020). On the most adjusted model, the year 2020 was correlated with a higher daptomycin consumption (1.53; p = 0.01). A greater number of inpatient beds (0.01; p < 0.001), the presence of orthopedic surgery activity in the HCF (1.66; p < 0.02), MRSA (4.38; p < 0.001) and MRCNS (0.61; p < 0.001) incidence densities were associated with a higher daptomycin use. The final model explained 18% of the observed variance.
Conclusions:
This study showed that daptomycin consumption was correlated to MRSA and MRCNS incidence densities, to the year 2020 and to non-modifiable HCF-related factors. Prevention of coagulase-negative staphylococci infections should be considered by antimicrobial stewardship teams when daptomycin use is going up in HCF.

Age plays a significant role due to differences in body composition among different age groups. Infants, for instance, have a higher proportion of total body water and lower albumin levels, a protein that binds drugs in the bloodstream. This unique composition in infants enhances the...

One crucial factor in drug-protein binding is the drug's lipophilicity or its affinity for fat. More lipophilic drugs tend to have higher binding extents. For example, highly lipophilic drugs like cloxacillin exhibit substantial protein binding, with as much as 95% of the drug binding to proteins. In...
