Sepsis & infection

Variation in antibiotic use across intensive care units in the Netherlands

J Crit CarePublished Retrospective observational study

Authors' conclusion

Antibiotic use varied significantly across ICUs, and case-mix did not explain these differences. The ASI provides important information in addition to the other antibiotic use metrics.

Study context

Population
All admissions to 11 Dutch ICUs, 2016–2019
Participants
51,205 / 3,059 / 1,094
Exposure
ICU-level variation in antibiotic use across 11 Dutch ICUs
  • All admissionsn = 51,205
  • Pneumonian = 3,059
  • Intra-abdominal sepsisn = 1,094
Outcome
ICU-level variation in systemic antibiotic use (DDD, DOT, length of therapy, antibiotic free days, AWaRe classification, ASI)
Methodological detailsmulticentre, registry and electronic health record data, case-mix adjusted (indirect standardization, ICU fixed effects)
