Quantifying the breadth of antibiotic exposure in sepsis and suspected infection using spectrum scores.
The purpose of this retrospective cohort study was to apply a validated method to describe the level of antimicrobial coverage in a cohort of patients with suspected infection and sepsis. The researchers conducted the study across 21 hospitals with patients admitted to the hospital through the ED between January 1, 2012, to December 31, 2017, with suspected infection or sepsis and receiving antibiotics during hospitalization. The researchers quantified the level of antimicrobial coverage using the Spectrum Score, a numerical score from 0 to 64. Of 364,506 hospital admissions through the ED, researchers identified 43.6% with suspected infection and 56.4% with sepsis. Inpatient mortality was greater among those with sepsis (8.4%) compared to those with suspected infection (1.2%). Patients with sepsis had higher median global Spectrum Scores and additive Spectrum Scores compared to those with suspected infection. Increased Spectrum Scores were related with inpatient mortality, even after covariate adjustments. Spectrum Scores quantify the inconsistency in antibiotic level among individual patients, between suspected infection and sepsis groups, over the course of the hospitalization, and across infection sources.

Clinical decision support improves blood culture collection before intravenous antibiotic administration in the emergency department.
This paper discusses the outcomes of using a clinical decision support (CDS) tool that was implemented in emergency departments (EDs) for sepsis patients to remind healthcare staff to take blood cultures before administration of intravenous (IV) antibiotics. The study compared timely blood culture collection outcomes prior to IV antibiotics for 54,538 adult ED patients 1 year before and after a CDS intervention implementation in the electronic health record. The baseline phase found that 46.1% had blood cultures prior to IV antibiotics, compared to 58.8% after the intervention. The CDS improved blood culture collection rates without increasing overutilization.

Temporal trends in antimicrobial prescribing during hospitalization for potential infection and sepsis.
This study examined whether the push to administer antimicrobials to prevent sepsis has increased antimicrobial use in general. This observational cohort study of hospitalized patients at 152 hospitals in 2 health care systems during 2013 to 2018 looked at almost 1.6 million patients (81% male), admitted via the emergency department with 2 or more systemic inflammatory response syndrome (SIRS) criteria. From 2013 to 2018 first antimicrobial administration to patients with sepsis decreased by 37 minutes. At the same time, antimicrobial use within 48 hours, days of antimicrobial therapy, and receipt of broad-spectrum coverage decreased among the broader cohort of patients with systemic inflammatory response syndrome (SIRS). This may have caused a decrease in in-hospital mortality, 30-day mortality, length of hospitalization, new MDR culture positivity, and new MDR blood culture positivity over the study period among both patients with sepsis and those with SIRS. For the overall hospital population there was no evidence that increasing antimicrobial timing for sepsis was associated with increasing antimicrobial use or impaired antimicrobial stewardship.

Association of diagnostic stewardship for blood cultures in critically ill children with culture rates, antibiotic use, and patient outcomes: results of the Bright STAR Collaborative.
The purpose of this AHRQ-funded prospective study was to assess the relationship between a 14-site PICU blood culture collaborative, the Bright STAR (Testing Stewardship for Antibiotic Reduction) collaborative, and culture rates, antibiotic use, and patient outcomes. The researchers collected data from each participating PICU across the United States and from the Children’s Hospital Association Pediatric Health Information System. The main outcome was blood culture rates, with secondary outcomes including: broad-spectrum antibiotic use and PICU rates of central line-associated bloodstream infection (CLABSI), Clostridioides difficile infection, readmission, length of stay, sepsis, severe sepsis/septic shock, and mortality. The study found that the blood culture rate preimplementation across the 14 PICUs was 149.4 per 1000 patient days per month, and the rate postimplementation was 100.5 for a 33% relative reduction postimplementation. For those same periods, the rate of antibiotic use decreased from 506 days per 1000 patient-days per month preimplementation to 440 days per 1000 patient-days per month postimplementation, which reflects a 13% relative reduction. Rates of CLABSI decreased from 1.8 to 1.1 per 1000 central venous line days per month, a 36% relative reduction. The variables of length of stay, readmission, sepsis, severe sepsis/septic shock, and mortality were similar before and after implementation. The researchers concluded that collaborative interventions can reduce blood culture and antibiotic use in the PICU.

Antimicrobial susceptibility profiles among neonatal early-onset sepsis pathogens.
This retrospective review examined antimicrobial susceptibility of infants ≥22 weeks' gestation who were cared for in Neonatal Research Network centers April 2015-March 2017. Nonsusceptibility was defined as intermediate or resistant on treatment results. The authors identified 239 pathogens (235 bacteria, 4 fungi) in 235 EOS cases among 217,480 live-born infants. Antimicrobial susceptibility data was available for 79.1% of isolates. All 81 Gram-positive isolates with ampicillin and gentamicin were susceptible in vitro. Among Gram-negative isolates with ampicillin and gentamicin susceptibility data, 76.6% isolates were nonsusceptible to ampicillin, 8.5% nonsusceptible to gentamicin, and 7.3% isolates were nonsusceptible to both. The authors estimated that overall 8% of EOS cases were caused by isolates nonsceptible to ampicillin and gentamicin and were most likely to occur among preterm, very-low birth weight infants.

Delivery characteristics and the risk of early-onset neonatal sepsis.
This retrospective cohort study identified term and preterm infants at lowest risk of culture-confirmed early-onset sepsis (EOS) using delivery characteristics and also determined antibiotic use among them. The study cohort included term and preterm infants born 2009 to 2014 with blood culture with or without cerebrospinal fluid culture obtained ≤72 hours after birth. Low EOS risk criteria included: cesarean delivery, without labor or membrane rupture before delivery, and no antepartum concern for intraamniotic infection or nonreassuring fetal status. Among 53,575 births, 7549 (14.1%) were evaluated and 41 (0.5%) of those infants had EOS. For 1121 evaluated infants there were low-risk delivery characteristics and none had EOS. Duration of antibiotics administered to infants born with and without low-risk characteristics was not different.
