Impact of reducing time-to-antibiotics on sepsis mortality, antibiotic use, and adverse events.
Researchers estimated benefits and harms of shortened time-to-antibiotics for sepsis. Their simulation study used a cohort of over 1.5 million hospitalizations via emergency department with more than two systemic inflammatory response syndrome criteria. The results showed that impacts of faster time-to-antibiotics for sepsis varied markedly across simulated hospital types; however, even in worst-case scenarios, new antibiotic-associated adverse events were rare.

Risk of misleading conclusions in observational studies of time-to-antibiotics and mortality in suspected sepsis.
Important studies indicate that every hour of sepsis that elapses until antibiotics are administered increases mortality. The researchers of this study found determined that analyses in the influential studies often adjusted for limited covariates, included patients with long delays until antibiotic administration, combined sepsis and septic shock, and used linear models presuming each hour of delay has equal impact on the sepsis and the patient. The purpose of this study was to assess the effect of the analytic decisions on the relationships between time-to-antibiotics and mortality. The researchers retrospectively identified 104,248 adults admitted from 2015-2022 to five hospitals with suspected infection. The patients included 25,990 with suspected septic shock and 23,619 with sepsis without shock. The study found that changing covariates, maximum time-to-antibiotics, and severity stratification altered the magnitude, direction, and significance of observed relationships between time-to-antibiotics and mortality. In a fully adjusted model of patients treated within 6 hours, every hour related with higher mortality for septic shock, but not sepsis without shock or suspected infection alone. Modeling every hour independently confirmed that every hour delay was related with greater mortality for septic shock, but only delays of greater than 6 hours were related with greater mortality for sepsis without shock.

Multicenter evaluation of a method to identify delayed diagnosis of diabetic ketoacidosis and sepsis in administrative data.
The objectives of this study were to derive a method of automated identification of delayed diagnosis of two serious pediatric conditions in the emergency department (ED). Subjects were patients under the age of 21 who had two EDs encounters within 7 days, the second resulting in a diagnosis of new-onset diabetic ketoacidosis (DKA) or sepsis. The results showed that delayed diagnosis was present in 89 % of DKA patients seen twice within 7 days. 17 % of sepsis patients were deemed to have delayed diagnosis; the authors noted that many children with sepsis delayed diagnosis may be identified using the proposed approach with low specificity, indicating a need for manual case review. The fewer days between ED encounters was the most important characteristic associated with delayed diagnosis.

A temperature- and age-adjusted shock index for emergency department identification of pediatric sepsis.
The objective of this retrospective cohort study was to derive a temperature- and age-adjusted mean shock index (TAMSI) for early identification of sepsis and septic shock in children with suspected infection. Researchers analyzed data on children who presented with suspected infection to a single emergency department over a 10-year period. Test characteristics for the TAMSI cutoffs were compared with those for the Pediatric Advanced Life Support (PALS) tachycardia or systolic hypotension cutoffs. The results showed that TAMSI achieved a similar negative likelihood ratio and improved positive likelihood ratio compared with PALS vital sign cutoffs for the prediction of septic shock, but did not improve on PALS for sepsis prediction among children with suspected infection.

Do prehospital sepsis alerts decrease time to complete CMS sepsis measures?
This retrospective cohort study examined the effects of a prehospital sepsis alert protocol on decreasing time to complete Centers for Medicare and Medicaid Services (CMS) sepsis core measures. The study included patients transported via EMS from December 1, 2018 to December 1, 2019 who met the criteria of the Maryland Statewide EMS sepsis protocol and compared outcomes between patients who activated a prehospital sepsis alert and patients who did not activate a prehospital sepsis alert. The Maryland Institute for Emergency Medical Services Systems had developed a sepsis protocol that instructed EMS providers to notify the nearest appropriate facility with a sepsis alert if a patient 18 years of age and older is suspected of having an infection and also presented with at least two of the following: temperature >38 °C or <35.5 °C, a heart rate >100 beats per minute, a respiratory rate >25 breaths per minute or end-tidal carbon dioxide less than or equal to 32 mmHg, a systolic blood pressure <90 mmHg, or a point of care lactate reading greater than or equal to 4 mmol/L. Median time to achieve all four studied CMS sepsis core measures was 103 min for patients who received a prehospital sepsis alert and 106.5 min for patients who did not receive a prehospital sepsis alert. Median time to completion was shorter for serum lactate collection (28 min. vs 35 min.), blood culture collection (28 min. vs 38 min.), and intravenous fluid administration (54 min. vs 61 min.) but was not significantly different for antibiotic administration (94 min. vs 103 min.) among patients who triggered a sepsis alert. The results question the effectiveness of prehospital sepsis alert protocols on decreasing time to complete CMS sepsis core measures.

Pneumosepsis survival in the setting of obesity leads to persistent steatohepatitis and metabolic dysfunction.
The purpose of this study was to explore the long-term effect of sepsis on pre-existing NAFLD and hyperglycemia. The researchers randomized male mice to either a high-fat diet or a control diet (CD). After 24 weeks on the diet, mice were inoculated with Klebsiella pneumoniae (Kpa). To assess whether persistent inflammation could be reproduced in other abnormal liver environments, mice were also challenged with Kpa after exposure to a methionine-choline-deficient high-fat diet. Finally, a retrospective cohort of 65,139 patients was analyzed to evaluate whether obesity was related with liver injury after sepsis. The study found that after Kpa inoculation, high-fat diet mice had normalized fasting blood glucose without a change in insulin sensitivity but with a notable decrease in pyruvate utilization. Liver examination revealed focal macrophage collections and a unique inflammatory gene signature on RNA analysis. In the clinical cohort, preobesity, and class 1 and class 2 obesity were related with higher odds of elevated aminotransferase levels 1-2 years after sepsis.

Outcomes of missed diagnosis of pediatric appendicitis, new-onset diabetic ketoacidosis, and sepsis in five pediatric hospitals.
This study’s objective was to determine 90-day complication rates and hospital utilization after a missed diagnosis of pediatric appendicitis, new-onset diabetic ketoacidosis (DKA), or sepsis. The authors evaluated patients under 21 years of age visiting five pediatric emergency departments (EDs) with a study condition. Case patients included had a preceding ED visit within 7 days of diagnosis and underwent case review to confirm a missed diagnosis. The authors compared complication rates and utilization between case and control patients after adjusting for age, sex, and insurance. They analyzed 29,398 children with appendicitis, 5366 with DKA, and 3622 with sepsis, of whom 429, 33, and 46, respectively, had a missed diagnosis. Patients with a missed appendicitis or DKA diagnosis had more hospital days and readmissions, but there were no significant differences for those with sepsis. Those with missed appendicitis were more likely to have abdominal abscess drainage or perforated appendicitis. Those with missed DKA were more likely to have cerebral edema, mechanical ventilation, or death. Those with missed sepsis were less likely to have mechanical ventilation.

Diagnostic performance and patient outcomes with c-reactive protein use in early-onset sepsis evaluations.
This study’s objective was to determine performance of C-reactive protein (CRP) in the diagnosis of early-onset sepsis, and to assess patient outcomes with and without routine use of CRP in infants in the neonatal intensive care unit (NICU). This retrospective cohort study looked at infants admitted to 2 NICUs from 2009 to 2014. During the time period, 10,134 infants were admitted, 89.9% had CRP, and 74.5% had blood culture obtained within 3 days of birth. CRP obtained plus/minus 4 hours had a sensitivity of 41.7%, specificity 89.9%, and positive likelihood ratio 4.12 in diagnosis of early-onset sepsis. When obtained 24-72 hours after blood culture, sensitivity of CRP increased significantly (89.5%), but specificity (55.7%) and positive likelihood ratio (2.02) decreased. Comparing the periods with (n = 4977) and without (n = 5135) routine use of CRP, the authors observed lower rates of early-onset sepsis evaluation (74.5% vs 50.5%), antibiotic initiation (65.0% vs 50.8%), and antibiotic prolongation in the absence of early-onset sepsis (17.3% vs 7.2%) in the later period.

Blood count derangements after sepsis and association with post-hospital outcomes.
Estimating long-term prognosis for sepsis survivors remains challenging. Prolonged inflammation following sepsis is linked to a higher likelihood of readmission and mortality. Complete blood count (CBC) parameters, as indicators of inflammation, might hold prognostic significance for sepsis survivors when measured at the time of hospital discharge. The purpose of this study was to assess the additional value of CBC parameters in predicting 90-day outcomes in sepsis survivors, beyond clinical features alone. Electronic health records were utilized to identify sepsis-related hospitalizations at US Veterans Affairs hospitals involving live discharge and relevant laboratory data (2013-2018). The researchers examined the relationship between eight CBC parameters and 90-day outcomes (mortality, readmission, cause-specific readmissions) using multivariable logistic regression models. The study found 155,988 eligible sepsis hospitalizations. Anemia and lymphopenia were the most prevalent blood count abnormalities at discharge. In multivariable models, all parameters correlated with the primary outcome of 90-day mortality or readmission and enhanced model discrimination beyond clinical features alone. Hemoglobin exhibited the highest prognostic distinction, with a 1.5-fold increase in the incidence of the primary outcome in the lowest quintile compared to the highest quintile Hemoglobin and neutrophil-lymphocyte ratio contributed the most added value in predicting the primary outcome and 90-day mortality independently. Absolute lymphocyte count offered minimal value in forecasting 90-day outcomes.

Antibiotic indications and appropriateness in the pediatric intensive care unit: a 10-center point prevalence study.
The purpose of this study was to describe indications and appropriateness of antibiotic orders in pediatric intensive care unit (PICU) patients. The study found that of 1462 patients admitted to participating PICUs, 58% had at least 1 antibiotic order, with 1277 antibiotic orders being reviewed. Common indications were empiric therapy for suspected bacterial infections without sepsis or septic shock, nonoperative prophylaxis, empiric therapy for sepsis or septic shock, community-acquired pneumonia, and post-operative prophylaxis. Appropriateness was evaluated for 985 orders for which an evidence-based heading for appropriateness could be created. Of these, 34% were categorized as inappropriate. Indications with the most orders classified as inappropriate were empiric therapy for suspected bacterial infection without sepsis or septic shock, sepsis or septic shock, CAP, ventilator-associated infections, and post-operative prophylaxis. The proportion of antibiotics classified as inappropriate differed across institutions.

Effectiveness of ultraviolet-c disinfection on hospital-onset gram-negative rod bloodstream infection: a nationwide stepped-wedge time-series analysis.
This study evaluated the effectiveness of enhanced terminal room cleaning with ultraviolet C (UV-C) disinfection in reducing gram-negative rod (GNR) infections. The authors used information regarding UV-C use and the timing of implementation through a survey of all Veterans Health Administration (VHA) hospitals providing inpatient acute care from January 2010 and December 2018. Among 128 Veterans Health Administration hospitals, 120 provided complete survey responses with 40 reporting implementations of UV-C systems. UV-C use was associated with a 19% lower incident of hospital-onset (HO) GNR bloodstream infection (BSI).

Outcomes associated with rural emergency department provider-to-provider telehealth for sepsis care: a multicenter cohort study.
The objective of this multicenter cohort study was to test the hypothesis that provider-to-provider tele-emergency department (tele-ED) care is associated with more 28-day hospital-free days and improved Surviving Sepsis Campaign (SSC) guideline adherence in rural emergency departments. Medical records of patients with sepsis were taken from rural hospitals in an established, on-demand, video tele-ED Midwestern network. Findings suggest that tele-ED cases did not have more 28-day hospital-free days or 28-day in-hospital mortality. A subgroup of patients treated by advanced practice providers suggest that mortality was lower in the cohort with tele-ED use in spite of no significant difference in complete SSC adherence. The researchers concluded that rural emergency department patients treated with provider-to-provider tele-ED care in a developed network showed similar clinical outcomes to those treated without.

Hospitals that report severe sepsis and septic shock bundle compliance have more structured sepsis performance improvement.
This study linked survey data on quality improvement (QI) practices from Iowa hospitals to severe sepsis/septic shock (SEP-1) performance data and mortality. All Iowa hospitals (100%) completed the survey. SEP-1 reporting hospitals were more likely to have sepsis QI practices, including reporting sepsis quality to providers (64% versus 38%) and using the case review process to develop sepsis care plans. Increased SEP-1 scores were not associated with sepsis QI practices. A sepsis registry was associated with decreased odds of being in the bottom quartile of sepsis mortality, and presence of a sepsis committee was associated with lower hospital-specific mortality.

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.

"These are our kids": qualitative interviews with clinical leaders in general emergency departments on motivations, processes, and guidelines in pediatric sepsis care.
Researchers sought to identify barriers and facilitators to pediatric sepsis care in general emergency departments (EDs), including care processes, the role of guidelines, and incentivized metrics. They interviewed medical directors, nurse managers, and quality coordinators. They found that leaders in general EDs were motivated to provide high-quality pediatric sepsis care but disagreed on whether reportable metrics would drive improvements. Leaders universally sought direct support from their nearest children's hospitals and actionable guidelines.

Attributable mortality of Candida bloodstream infections in the modern era: a propensity score analysis.
The purpose of this retrospective cohort study was to quantify the mortality attributed to Candida bloodstream infections (BSI). The researchers identified 626 adult patients with Candida BSI that were frequency-matched with 6269 control patients with similar candida BSI risk-factors. The study found that the 90-day crude mortality rate was 42.4% for Candida BSI cases and 17.1% for frequency matched controls. After propensity score-matching, the attributable risk difference for 90-day mortality was 28.4% with hazard ratio (HR) of 2.12. In the stratified analysis, the 90-day mortality risk was highest in patients in the lowest risk quintile to develop Candida BSI. Patients in this lowest risk quintile accounted for 61% of the untreated patients with Candida BSI. Sixty-nine percent of untreated patients died versus 35% of treated patients.

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.

An economic and health outcome evaluation of telehealth in rural sepsis care: a comparative effectiveness study.
The purpose of this study will be to assess the impact of provider-focused video telehealth in rural hospital emergency departments (ED) on costs and long-term outcomes for patients with sepsis. Using Medicare administrative claims, the researchers will compare telehealth-subscribing hospitals and control hospitals to assess the differences in total health care expenditures, category-specific costs, length of stay, readmissions, and mortality. The researchers intend for the study results to demonstrate the association between telehealth utilization and sepsis care total expenditures.

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.

Validation of the pediatric Sequential Organ Failure Assessment score and evaluation of Third International Consensus Definitions for Sepsis and Septic Shock Definitions in the pediatric emergency department.
This study analyzed whether a measure used to quantity organ dysfunction, the Sequential Organ Failure Assessment (SOFA) in adults can also be used for critically ill children in an emergency department (ED) population. This retrospective cohort study took place in 9 US children’s hospitals included in the Pediatric Emergency Care Applied Research Network (PECARN registry from January 2012 to January 31, 2020. A score of 2 or more can indicate an infection. Almost 4 million ED visits were included, with 3.2% having a pSOFA score of 2 or more. The pSOFA score showed poor sensitivity as a screening tool for hospital mortality but children with a pSOfA score of 2 or less were at very low risk of death, with high specificity and negative predictive value.

Therapeutic hyperthermia is associated with improved survival in afebrile critically ill patients with sepsis: a pilot randomized trial.
This study’s objective was to test the hypothesis that forced-air warming of critically ill afebrile sepsis patients improves immune function compared to standard temperature management. Patients were considered eligible patients if they were mechanically ventilated septic adults with: 1) a diagnosis of sepsis within 48 hours of enrollment; 2) anticipated need for mechanical ventilation of greater than 48 hours; and 3) a maximum temperature less than 38.3°C within the 24 hours prior to enrollment. Intervention treatment was external warming using a forced-air warming blanket for 48 hours, with a goal temperature 1.5°C above the lowest temperature documented in the previous 24 hours. The authors enrolled 56 patients in this randomized, controlled trial. Participants allocated to external warming had lower 28-day mortality (18% vs 43%) and more 28-day hospital-free days. No differences were observed between the groups in HLA-DR expression or IFN-γ production.

A task analysis of central line-associated bloodstream infection (CLABSI) surveillance in home infusion therapy.
This study’s objective was to describe barriers to, facilitators for, and suggested strategies for successful home infusion central line associated bloodstream infection (CLABSI) surveillance. The authors conducted semi-structured interviews with team members involved in CLABSI surveillance at 5 large home infusion agencies to explore work systems used by members for home infusion. They analyzed 21 transcribed interviews qualitatively for themes. Eight steps for performing CLABSI surveillance were revealed. Major surveillance barriers identified included the need for training of the surveillance staff, lack of a standardized definition, inadequate information technology support, struggles communicating with hospitals, inadequate time, and insufficient clinician engagement and leadership support.

Association of registered nurse staffing with mortality risk of Medicare beneficiaries hospitalized with sepsis.
The purpose of this cross-sectional study was to determine if registered nurse workload was related with mortality in Medicare beneficiaries admitted to an acute care hospital with sepsis. The researchers evaluated the records of Medicare beneficiaries ages 65 to 99 years with a primary diagnosis of sepsis that was present on admission to 1 of 1958 nonfederal, general acute care hospitals that had data on CMS SEP-1 scores and registered nurse workload. Researchers utilized 2018 data from the American Hospital Association Annual Survey, CMS Hospital Compare, and Medicare claims. The patient outcome of interest was mortality within 60 days of admission. The study found that 702,140 Medicare beneficiaries with a mean age of 78.2 years, 51% of whom were women, had a diagnosis of sepsis. In a multivariable regression model, each additional registered nurse hour per patient day (HPPD) was associated with a 3% decrease in the odds of 60-day mortality. The researchers concluded that hospitals which provide more registered nurse hours of care could possibly decrease the likelihood of mortality in Medicare beneficiaries with sepsis.

Hospital nurse staffing and sepsis protocol compliance and outcomes among patients with sepsis in the USA: a multistate cross-sectional analysis.
The timely and effective administration of sepsis treatment may improve sepsis outcomes, and those improvements may provide evidence of the need for mandated reporting of adherence to sepsis care protocol. The purpose of the study was to better understand the association between patient-to-nurse staffing ratios, sepsis protocol compliance, and patient outcomes. The researchers conducted a cross-sectional study utilizing linked data from 537 hospitals from across California, Florida, Illinois, Pennsylvania, New Jersey, and New York (representing 252,699 Medicare inpatients with sepsis present on admission), nurse and hospital surveys, and Centers for Medicare and Medicaid Services Hospital Compare and the corresponding MedPAR patient claims. The study found that every additional patient per nurse was associated with greater odds of mortality, readmission, ICU admission, and greater risk of relative duration of stay. Every 10% increase in compliance of sepsis protocol was only associated with a shorter duration of stay. The study concluded that improvements in nurse staffing and the nurse-to-patient ratios had a greater impact on sepsis infection outcomes than compliance with protocols.
