Abstract
Neonatal sepsis is an important cause of neonatal morbidity and mortality. A significant proportion of bacteria causing neonatal sepsis is resistant to multiple antibiotics, not only to the usual empirical first-line regimens, but also to second- and third-line antibiotics in many neonatal intensive care units (NICUs). NICUs have unique antimicrobial stewardship goals. Apart from antimicrobial resistance, NICUs have to deal with another problem, namely biofilm infections, since neonates often have central and peripheral lines, tracheal tubes and other foreign bodies for a prolonged duration. The aim of this review is to describe traditional and novel ways to fight antibiotic-resistant bacteria and biofilm infections in NICUs. The topics discussed will include prevention and control of the spread of infection in NICUs, as well as the wise use of antimicrobial therapy and ways to fight biofilm infections.

A simple and feasible antimicrobial stewardship program in a neonatal intensive care unit of a Japanese community hospital. J Infect Chemother 2019; 25:860-865. [PMID: 31109751 DOI: 10.1016/j.jiac.2019.04.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2018] [Revised: 03/30/2019] [Accepted: 04/16/2019] [Indexed: 12/28/2022]
Abstract
BACKGROUND Although tertiary hospitals have successfully introduced ASPs by antimicrobial stewardship teams, lots of community hospitals without pediatric infectious disease specialists have difficulty implementing ASP. We present a successful implementation of simple and feasible NICU antimicrobial stewardship program in a Japanese community hospital. METHOD We developed a protocol of antimicrobial treatment in our NICU department and have implemented the protocol from September 2017. The protocol consists of start and stop of criteria antimicrobial treatment, weekend report of blood culture result from microbiology department and stopping ordering antimicrobials beforehand for the next day. We compared days of therapy (DOT) during the post-implementation period (September 2017 to August 2018) with that of pre-implementation period (March 2013 to August 2017). RESULT In pre- and post-ASP implementation periods, 913 and 194 patients were analyzed. DOT was 175.1 and 41.6/1000 patient-days, respectively (p < 0.001) with 76.2% reduction. The percentage of neonates who had any antimicrobials and the percentage of prolonged antimicrobial treatments among neonates who had any antimicrobials decreased significantly (55.3% vs 20.6%, p < 0.001 and 65.0% vs 32.5%, p < 0.001). The protocol compliance rates were also significantly different (55.4% vs 95.4%; p < 0.001). The methicillin-resistant rate of S.aureus rates were significantly reduced in post-ASP period (31.1% vs 12.9%; p = 0.002). CONCLUSION This ASP program was easily implemented in a NICU department of a community hospital and significantly reduced antimicrobial prescription. This kind of simple protocol may be successfully scaled-up in resource limited community hospitals without no pediatric infectious disease specialists or antimicrobial stewardship team.

Abstract
Antibiotics are invaluable in the management of neonatal infections. However, overuse or misuse of antibiotics in neonates has been associated with adverse outcomes, including increased risk for future infection, necrotizing enterocolitis, and mortality. Strategies to optimize the use of antibiotics in the neonatal intensive care unit include practicing effective infection prevention, improving the diagnostic evaluation and empiric therapy for suspected infections, timely adjustment of therapy as additional information becomes available, and treating proven infections with an effective, narrow-spectrum agent for the minimum effective duration. Antibiotic stewardship programs provide support for these strategies but require the participation and input of neonatologists as stakeholders to be most effective.

Abstract
BACKGROUND Prolonged or unnecessary antibiotic use is associated with adverse outcomes in neonates. Our objectives were to quantify all antibiotic use in a Level-III neonatal intensive care unit and to identify scenarios where their use could be reduced. METHODS Surveillance and evaluation of all antibiotic use provided to every infant admitted to a Level-III neonatal intensive care unit from 10/3/11 to 11/30/12 was performed. Types of antibiotics, reasons for their initiation, discontinuation and duration, as well as clinical, laboratory and outcome data were recorded. Antibiotic use was quantified by days of therapy (DOT) per 1000 patient-days (PD). RESULTS A total of 1607 infants were included. The total antibiotic use was 9165 DOT (343.2 DOT/1000 PD; 5.7 DOT/infant). Seventy-two percent of infants received 1 (43%) or more (29%) courses of antibiotics. Gentamicin (46%), ampicillin (39%) and oxacillin (8%) were the most frequently used agents. Ninety-four percent of antibiotic use (323 DOT/1000 PD) was empiric therapy for suspected infection. Sixty-three percent (216.2 DOT/1000 PD) was discontinued at approximately 48 hours when cultures were sterile (68%>48 hours, 32%≤48 hours). Twenty-six percent of all antibiotic use (89.4 DOT/1000 PD) was therapy for ≥5 days despite sterile cultures; pneumonia (16%) and "culture-negative" sepsis (8%) were the major contributors. Five percent (17.4 DOT/1000 PD) of antibiotic use was for culture-proven sepsis, 5% (16.6 DOT/1000 PD) was penicillin prophylaxis for group B Streptococcus and 1% (3.5 DOT/1000 PD) was preprocedural prophylaxis. CONCLUSIONS Narrow-spectrum therapy accounted for >92% of antibiotic use and would not be monitored by most stewardship programs. Only 5% of antibiotic usage was due to culture-proven infection. Pneumonia and "culture-negative" sepsis were frequent reasons for prolonged therapy; further study of these conditions may allow reduction in treatment duration.

Abstract
There are unique challenges to antimicrobial stewardship in neonatal intensive care units (NICUs). Diagnosis of infection is difficult as neonates can have nonspecific signs and symptoms. Between and within NICUs, significant variation exists in the treatment duration of suspected sepsis and pneumonia. Development of multidisciplinary teams and meaningful metrics are essential for sustainable antibiotic stewardship. Potential stewardship interventions include optimizing culturing techniques, guiding empiric therapy by NICU-specific antibiograms, using ancillary laboratory tests, and promptly discontinuing therapy once infection is no longer suspected. Use of large neonatal databases can be used to benchmark antibiotic use and conduct comparative effectiveness research.

Abstract
AIM To explore risk patterns for presumed and definite, early and late neonatal bacteremia. METHODS We studied 1106 extremely low gestational age newborns who survived until postnatal day 28. We defined early definite bacteremia as a positive bacterial culture in the first week and definite late bacteremia as a positive bacterial culture in week 2, 3 or 4. Bacteremia was presumed if antibiotics were given for more than 72 h despite negative blood cultures. RESULTS Risk patterns did not differ much for presumed and definite bacteremia in the first postnatal month. While maternal and pregnancy characteristics were associated with early bacteremia, neonatal comorbidities, especially NEC, were the main antecedents/correlates of late bacteremia. All four categories of bacteremia were associated with younger gestational age and lower birth weight. Infants with presumed and definite bacteremia had similar distributions of days of ventilation and oxygenation. CONCLUSION Definite and presumed late bacteremias have rather similar risk patterns, while those of early and late bacteremia differ appreciably.
