Rationale:
Almost 60% of antibiotics in frail elderly is prescribed for alleged UTI. About half of the antibiotics for UTI in this population are prescribed for non-specific signs and symptoms; a substantial part of these prescriptions might not be necessary.
Research question:
Does a tailored multifaceted antibiotic stewardship intervention reduce antibiotic use for UTI in residential care homes and nursing homes attended by general practitioners (GPs)?
Study design, setting and population:
A pragmatic cluster randomised controlled trial using a modified community-based participatory action research approach. In the intervention group the latest UTI guidelines (which are standard care) are actively implemented at the level of the GP/caregivers. Residents ≥ 70 year with ADL dependency from 34 care homes + attending GP practices will participate in Norway, Sweden, Poland and the Netherlands.
Methods:
The study has two measurement periods; a baseline period (5 months) and a follow-up period (7 months). In between the antibiotic stewardship intervention will be tailored and implemented in intervention practices. GPs will prospectively register suspected UTIs on standardized registration forms and (study) nurses/assistants will follow-up patients at day 7 and day 21 for each UTI.
Patients will be enrolled prior to the start of the study.
- June-August 2019: patient are recruited, informed consent is obtained, baseline characteristics of patients are recorded
- Sept 2019: study starts (from this moment onwards, the outcomes are being assessed).
Data analysis:
The primary analysis will be to assess the number of prescriptions of antibiotics for suspected UTI in the follow-up period, correcting for the baseline period and controlled for pre-specified confounders, using a generalized linear mixed model for Poisson distributions.
