Reducing Vancomycin Use in a Level IV NICU.

BACKGROUND AND OBJECTIVES: Vancomycin remains one of the most commonly prescribed antibiotics in NICUs despite recommendations to limit its use for known resistant infections. Baseline data revealing substantially higher vancomycin use in our NICU compared to peer institutions informed our quality improvement initiative. Our aim was to reduce the vancomycin prescribing rate in neonates hospitalized in our NICU by 50% within 1 year and sustain for 1 year. METHODS: In the 60-bed level IV NICU of an academic referral center, we used a quality improvement framework to develop key drivers and interventions including (1) physician education with benchmarking antibiotic prescribing rates; (2) pharmacy-initiated 48-hour antibiotic time-outs on rounds; (3) development of clinical pathways to standardize empirical antibiotic choices for early-onset sepsis, late-onset sepsis, and necrotizing enterocolitis; coupled with (4) daily prospective audit with feedback from the antimicrobial stewardship program. RESULTS: We used statistical process u-charts to show vancomycin use declined from 112 to 38 days of therapy per 1000 patient-days. After education, pharmacy-initiated 48-hour time-outs, and development of clinical pathways, vancomycin use declined by 29%, and by an additional 52% after implementation of prospective audit with feedback. Vancomycin-associated acute kidney injury also declined from 1.4 to 0.1 events per 1000 patient-days. CONCLUSIONS: Through a sequential implementation approach of education, standardization of care with clinical pathways, pharmacist-initiated 48-hour time-outs, and prospective audit with feedback, vancomycin days of therapy declined by 66% over a 1-year period and has been sustained for 1 year.

Early Glycemic Profile Is Associated with Brain Injury Patterns on Magnetic Resonance Imaging in Hypoxic Ischemic Encephalopathy.

OBJECTIVE: To investigate whether the early glycemic profile in infants with hypoxic ischemic encephalopathy is associated with distinct patterns of brain injury on magnetic resonance imaging (MRI). STUDY DESIGN: We performed a secondary analysis of 178 prospectively enrolled infants who received therapeutic hypothermia for hypoxic ischemic encephalopathy. Glycemic profiles were identified by glucose concentrations within 24 hours after birth: normoglycemia (all glucose concentrations of >47 to ≤150 mg/dL; n = 62); hypoglycemia (≥1 concentration ≤47 mg/dL; n = 17); hyperglycemia (≥1 concentration >150 mg/dL; n = 76); and labile glucose (both hypoglycemia and hyperglycemia; n = 23). Patterns of brain injury were identified for 151 infants based on Barkovich scores from the postrewarming brain MRIs at a median age of 9 days. RESULTS: A normal brain MRI was reported in 37 of 62 infants (60%) with normal blood glucose values compared with 37 of 116 infants (32%) with an abnormal glucose profile (adjusted for Sarnat stage of encephalopathy and Apgar score at 5 minutes; P = .02). The distribution of MRI patterns of brain injury differed among the glycemic groups (P = .03). The odds of predominant watershed or focal-multifocal injury was higher in infants with hypoglycemia (aOR, 6; 95% CI, 1.5-24.2) and labile glucose (6.6; 95% CI, 1.6-27) compared with infants with normoglycemia. Infants with labile glucose had higher odds (5.6; 95% CI, 1.1-29.3) of predominant basal ganglia or global injury compared with infants with normal blood glucose values. CONCLUSIONS: The early glycemic profile in infants with hypoxic ischemic encephalopathy is associated with specific patterns of brain injury on MRI. Further investigation is needed to explore its prognostic significance and role as a phenotype biomarker.

An unusual cause of recurrent cheek abscess: a clinical case

We report the case of a 16-year-old female who presented to us with a recurrent cheek abscess following a blow to the cheek. On drainage of the abscess, a piece of betel nut was retrieved from the cheek. The patient recalled having a betel nut in her mouth at the time of the blow.
