The objective of the ANNA-study, a cluster randomized controlled trial (cRCT) was to investigate whether an electronic health record integrated decision tool, combined with supportive interventions, results in more appropriate antibiotic prescribing in nursing home residents with suspected urinary tract infection, without negative consequences for residents. This study was conducted in 16 nursing homes in the Netherlands from March 2019 – March 2020.
Parallel to the main study a process evaluation study was conducted, with the objective to assess the internal and external validity ofthe cRCT, and to identify facilitators and barriers in implementing the intervention.
