Antibiotic use among infants admitted to neonatal intensive care units.
The purpose of this cross-sectional study was to examine antibiotic exposure, days of therapy, types of antibiotics, and changes in use patterns among newborns in neonatal intensive care units (NICUs) across the U.S. Data for almost 1.4 million infants were taken from the Premier Healthcare Database. The most common antibiotics prescribed during the study period were ampicillin, gentamicin, vancomycin, and cefotaxime. Antibiotic use declined substantially over time, primarily because of reductions in ampicillin and gentamicin. The authors noted that these findings probably reflect the penetration of national calls for neonatal antibiotic stewardship efforts and refined early-onset infection risk-assessment strategies; shortage and subsequent discontinuation of cefotaxime may have played a role in the sharp decline in its use and the related increase in ceftazidime use.

Cluster analysis driven by unsupervised latent feature learning of medications to identify novel pharmacophenotypes of critically ill patients.
This study used a machine learning approach (Restricted Boltzmann Machine) to perform an unsupervised analysis of 991 medication profiles of patients managed in the intensive care unit (ICU) to explore pharmacophenotypes that correlated with ICU complications (e.g., mechanical ventilation) and patient-centered outcomes (e.g., length of stay, mortality). The authors observed six unique pharmacophenotypes, with unique medication profiles and clinically relevant differences in ICU complications and patient-centered outcomes. While pharmacophenotypes 2 and 4 had no statistically significant difference in ICU length of stay, duration of mechanical ventilation, or duration of vasopressor use, their mortality differed significantly (9.0% vs. 21.9%). All but pharmacophenotype 4 had a mortality rate ranging from 2.5 to 9%. This approach has shown promise in classifying the heterogenous syndromes of critical illness to predict treatment response and guide clinical decision support systems but have never included comprehensive medication information.

Antibiotic spectrum index: a new tool comparing antibiotic use in three NICUs.
This study looked at a new tool called the antibiotic spectrum index (ASI) which quantifies antibiotic exposure by relative antimicrobial activity, adding information to exposure measured by days of therapy (DOT). This index was tested with very low-birth-weight infants (VLBW, <1500g) in 3 level-4 NICUs for 2 years at 2 sites and for 1 year at a third site. The authors calculated the ASI per antibiotic days and DOT per patient days for all admitted VLBW infants <32 weeks gestational age. The site with the highest DOT per patient days was found to have the lowest ASI per antibiotic days and the site with the highest mortality and infection rates were found to have the highest ASI per antibiotic days. Antibiotic utilization varied by center.

Critical care pharmacists: improving care by increasing access to medication expertise.
This article discusses the shortage and need for critical care pharmacists in ICUs to improve care and prevent medication errors. There is a gap in critical care pharmacists with both low supply and low demand. Identifying the optimal patient:pharmacist ratio in the ICU is a key question. The authors discuss ways to reduce the gap by increasing the number of critical care pharmacy residency programs and including critical care pharmacists more in multidisciplinary rounds. The authors developed a toolkit for increasing critical care pharmacy services in five actionable steps and provide an annotated bibliography of key references.

Association of vancomycin plus piperacillin-tazobactam with early changes in creatinine versus cystatin C in critically ill adults: a prospective cohort study.
The purpose of this study was to test the hypothesis that the association between vancomycin + piperacillin-tazobactam and increased acute kidney injury (AKI) risk by contrasting changes in creatinine concentration after antibiotic initiation with changes in cystatin C concentration. The researchers included patients enrolled in the Molecular Epidemiology of SepsiS in the ICU (MESSI) prospective cohort who were treated for greater than or equal to 48 h with vancomycin + piperacillin-tazobactam or vancomycin + cefepime. The kidney function biomarkers of blood urea nitrogen (BUN), creatinine, and cystatin C were measured before antibiotic treatment and again on day two after initiation. Creatinine-defined AKI and dialysis were evaluated through day14, and mortality was assessed through day 30. The study found that in the 739 patients vancomycin + piperacillin-tazobactam was associated with a higher percentage increase of creatinine at day-two and a higher incidence of creatinine-defined AKI: rate ratio. Vancomycin + piperacillin-tazobactam was not associated with change in alternative biomarkers. The researchers concluded that the study supports the hypothesis that vancomycin + piperacillin-tazobactam effects on creatinine represent pseudotoxicity.

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.

Improving vancomycin stewardship in critically ill children.
The purpose of this study was to describe a quality improvement intervention to reduce the use of vancomycin in a tertiary care Pediatric Intensive Care Unit. Over a period of 3 years, the researchers conducted 3 quality improvement (QI) interventions including 1) stakeholder education, 2) development of a consensus-based guideline for empiric vancomycin use, and 3) implementation of the guideline through clinical decision support. The study found that of 1276 episodes of suspected bacterial infection, a total of 19 cases of bacteremia (1.5%) due to organisms requiring vancomycin therapy were identified, including 6 MRSA bacteremias. Over the 3-year period of the QI project, overall vancomycin DOT per 1000 patient days in the PICU decreased from a baseline mean of 182 DOT per 1000 patient days to 109 DOT per 1000 patient days (a 40% reduction). The study concluded that the intervention reduced overall vancomycin use in the Pediatric Intensive Care Unit without evidence of harm.

Ketamine use for tracheal intubation in critically ill children is associated with a lower occurrence of adverse hemodynamic events.
Tracheal intubation in critically ill children with shock poses a risk of hemodynamic compromise. Ketamine has been considered the drug of choice for induction in these patients, but limited data exist. In this study, the authors investigated whether the administration of ketamine for tracheal intubation in critically ill children with or without shock was associated with fewer adverse hemodynamic events compared with other induction agents. They also investigated if there was a dose dependence for any association between ketamine use and adverse hemodynamic events.

Effect of best practice advisories on sedation protocol compliance and drug-related hazardous condition mitigation among critical care patients.
This study’s goal was to determine whether best practice advisories improved sedation protocol compliance and could mitigate propofol-related hazardous conditions in adult ICUs. Two adult ICUs at two academic medical centers that shared the same sedation protocol were used to identify adults admitted between 2016 to January 31 2018 who received a continuous infusion of propofol. A total of 1,394 patients were included in the study cohort. The best practice advisory improved sedation protocol compliance and resulted in providers discontinuing propofol an average of 16.6 hours sooner than pre-best practice advisory.

Baby NINJA (Nephrotoxic Injury Negated by Just-in-Time Action): reduction of nephrotoxic medication-associated acute kidney injury in the neonatal intensive care unit.
The purpose of this study was to test if acute kidney injury (AKI) is preventable in patients in the neonatal intensive care unit and if infants at high-risk of nephrotoxic medication-induced AKI can be identified using a systematic surveillance program previously used in the pediatric non-intensive care unit setting. The authors concluded that a systematic surveillance program to identify high-risk infants can prevent nephrotoxic-induced AKI and has the potential to prevent short and long-term consequences of AKI in critically ill infants.

Medication safety in two intensive care units of a community teaching hospital after electronic health record implementation: sociotechnical and human factors engineering considerations.
This study examined the impact of electronic health record (EHR) implementation in two intensive care units (ICUs). The authors assessed 1254 consecutive admissions before and after an EHR implementation. They identified 4063 medication-related events either pre-implementation (2074 events) or post-implementation (1989 events). The overall potential for harm due to medication errors decreased post-implementation, but only 2 of the 3 error rates were significantly lower post-implementation. They observed reductions in rates of medication errors per admission at the stages of transcription, dispensing, and administration. In the ordering stage, 4 error types decreased post-implementation (orders with omitted information, error-prone abbreviations, illegible orders, failure to renew orders) and 4 error types increased post-implementation (orders of wrong drug, orders containing a wrong start or stop time, duplicate orders, orders with inappropriate or wrong information).

Procalcitonin-guided antibiotic discontinuation and mortality in critically ill adults: a systematic review and meta-analysis.
This study is a systematic review and meta-analysis on survival outcomes of using procalcitonin (PCT)-guided antibiotic discontinuation on critically ill adults. The study quality was assessing with the Cochrane risk of bias tool, and GRADEpro was used to grade evidence. PCT-guided discontinuation was associated with decreased mortality, but there was a high risk of bias in many of the studies reviewed with a low certainty of evidence. The authors suggest properly designed studies with mortality as the primary outcome is needed to further answer this question.

Cognitive impairment, anesthesia, and critical illness: learning from the past to gain perspective on the future.
This study examined the link between cognitive impairment, ICU admission and anesthesia. The author’s hypothesis was that patients with cognitive impairment would be more likely to undergo surgical procedures. However, analysis using data from the Mayo Clinical Study on Aging on 1,977 cognitive normal patients, 387 patients with mild cognitive impairment (MCI), and 72 patients with established dementia found that patients with MCI were more likely to undergo anesthesia and those with dementia were less likely to undergo procedural anesthesia. The author hypothesizes this may be linked to impaired decision-making of the patient and the risk-benefit analysis of performing surgery on patients with established dementia. However, ICU admissions were increased in patients with MCI and dementia.

Essential resources and strategies for antibiotic stewardship programs in the acute care setting.
This study measured the success of antibiotic stewardship programs to rates of antibiotic resistant disease. A survey was conducted of US stewardship programs using a cross-section of members of 3 infectious diseases subspecialty societies. Two-hundred forty-four respondents from a variety of acute care settings filled out the survey. Eighty-five percent of surveyed programs demonstrated at least 1 improved outcome in the prior 2 years. Every 0.50 increase in pharmacist and physician full-time equivalent (FTE) support predicted a 1.48-fold increase in demonstration effectiveness.

Outcomes of protocolised analgesia and sedation in a neurocritical care unit.
Researchers conducted a retrospective cohort study of 1197 mechanically ventilated patients admitted to a 12-bed neurocritical care unit (NCCU) over four years in order to evaluate the effect of an analgesia-based sedation protocol on medication use and costs in the NCCU. The protocol resulted in increased in fentanyl use and decreased in propofol use, but their findings indicate no effect on healthcare utilization, healthcare costs, or in-hospital mortality. Based on these results, the researchers suggest that similar NCCUs should consider using population-specific protocols to manage analgesia and sedation.

The impact of critically ill children on paediatric ED medication timeliness.
The presence of critically ill patients may impact care for other ED patients. The researchers evaluated whether the presence of a critically ill child was associated with the time to (1) receipt of the first medication among other patients, and (2) administration of diagnosis-specific medications. They concluded that the presence of critically ill patients was associated with a delay in medication administration to others.
