Objective:
We aimed to reduce our monthly antibiotic usage rate (AUR, days of treatment per 1,000 patient-days) in the neonatal intensive care unit (NICU) from a baseline of 330 (July 2015-April 2016) to 200 by December 2018.
Study Design:
We identified three key drivers as follows: (1) engaging NICU charge nurses, (2) challenging the culture of culture-negative sepsis, and (3) reducing central-line associated bloodstream infections (CLABSI). Our main outcome was AUR. The percentage of culture-negative sepsis that was treated with antibiotics for >48 hours and CLABSI was our process measure. We used hospital cost/duration of hospitalization and mortality as our balancing measures.
Results:
After testing several plan-do-study-act (PDSA) cycles, we saw a modest reduction in AUR from 330 in the year 2016 to 297 in the year 2017. However, we did not find a special-cause variation in AUR via statistical process control (SPC) analysis (u'-chart). Thereafter, we focused our efforts to reduce CLABSI in January 2018. As a result, our mean AUR fell to 217 by December 2018. Our continued efforts resulted in a sustained reduction in AUR beyond the goal period. Importantly, cost of hospitalization and mortality did not increase during the improvement period.
Conclusion:
Our sequential quality improvement (QI) efforts led to a reduction in AUR. We implemented processes to establish a robust antibiotic stewardship program that included antibiotic time-outs led by NICU charge nurses and a focus on preventing CLABSI that were sustained beyond the QI period.
Key Points:
· This is a quality improvement project to reduce antibiotic usage in NICU.. · Charge nurses should take charge to reduce infections in NICU.. · Central line infections should be reduced to decrease antibiotic usage..

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
