Objective:
Patients receiving maintenance hemodialysis are frequently exposed to antibiotics, a proportion of which may not be necessary thereby increasing the risk of antibiotic-associated adverse events. Antimicrobial stewardship programs remain underdeveloped in outpatient dialysis facilities. This study aimed to quantify antibiotic prescribing trends across in-center dialysis units and identify patient- and facility-level factors associated with decreased antibiotic use to inform the future stewardship strategies.
Design:
Retrospective observational cohort study among 16 in-center hemodialysis units.
Methods:
Antibiotic prescribing patterns and patient- and unit-level characteristics were analyzed among patients receiving maintenance hemodialysis from April 1, 2021, to March 31, 2024. Antibiotic prescribing trends were analyzed using general linear models. Generalized estimating equations were used to identify factors associated with decreased prescribing.
Results:
A total of 937 (26.4%) among 3,549 patients received ≥1 antibiotic dose, with an average of 15.36 doses per 100 patient-months, ranging from 4.82 to 30.87 doses/100 patient months. Types and frequency of antibiotics prescribed among units varied considerably. Trends in antibiotic prescribing did not decrease among 10 (62.5%) of the in-center hemodialysis units. Patient-level characteristics in units associated with a decrease in prescribing included Black race, Hispanic ethnicity, age 56-65, and diabetes as the cause of kidney failure.
Conclusions:
There is substantial variability in antibiotic prescribing across dialysis units. Decreasing trends in prescribing were observed in a subset of units and were associated with patient-level factors. These findings support the need for developing and implementing antimicrobial stewardship programs targeting the outpatient dialysis setting.
Insights
Antibiotic prescribing varies widely in hemodialysis units. Decreased use was linked to patient factors, highlighting the need for antimicrobial stewardship programs in dialysis care.
Area of Science:
- Nephrology
- Infectious Diseases
- Public Health
Background:
- Antibiotic overuse in maintenance hemodialysis patients increases adverse events.
- Antimicrobial stewardship programs are lacking in outpatient dialysis facilities.
Purpose of the Study:
- Quantify antibiotic prescribing trends in in-center hemodialysis units.
- Identify patient and facility factors associated with reduced antibiotic use.
- Inform antimicrobial stewardship strategies for dialysis settings.
Main Methods:
- Retrospective observational cohort study of 16 in-center hemodialysis units.
- Analysis of antibiotic prescribing patterns from April 2021 to March 2024.
- Statistical modeling (general linear models, GEE) to identify prescribing trends and associated factors.
Main Results:
- 26.4% of 3,549 patients received antibiotics, with significant variation in prescribing rates (4.82-30.87 doses/100 patient-months).
- Antibiotic prescribing did not decrease in 62.5% of units.
- Decreased prescribing was associated with patient factors: Black race, Hispanic ethnicity, age 56-65, and diabetes as cause of kidney failure.
Conclusions:
- Substantial variability exists in antibiotic prescribing across hemodialysis units.
- Decreasing prescribing trends were observed in some units and linked to patient characteristics.
- Development and implementation of antimicrobial stewardship programs are crucial for outpatient dialysis settings.
