BACKGROUND: Late recognition of in-hospital deterioration is a source of preventable harm. Emergency transfers (ET), when hospitalized patients require intensive care unit (ICU) interventions within 1 h of ICU transfer, are a proximal measure of late recognition associated with increased mortality and length of stay (LOS).

OBJECTIVE: To apply diagnostic process improvement frameworks to identify missed opportunities for improvement in diagnosis (MOID) in ETs and evaluate their association with outcomes.

DESIGN, SETTINGS, AND PARTICIPANTS: A single-center retrospective cohort study of ETs, January 2015 to June 2019. ET criteria include intubation, vasopressor initiation, or 60 mL/kg fluid resuscitation 1 h before to 1 h after ICU transfer. The primary exposure was the presence of MOID, determined using SaferDx. Cases were screened by an ICU and non-ICU physician. Final determinations were made by an interdisciplinary group. Diagnostic process improvement opportunities were identified.

MAIN OUTCOME AND MEASURES: Primary outcomes were in-hospital mortality and posttransfer LOS, analyzed by multivariable regression adjusting for age, service, deterioration category, and pretransfer LOS.

RESULTS: MOID was identified in 37 of 129 ETs (29%, 95% confidence interval [CI] 21%-37%). Cases with MOID differed in originating service, but not demographically. Recognizing the urgency of an identified condition was the most common diagnostic process opportunity. ET cases with MOID had higher odds of mortality (odds ratio 5.5; 95% CI 1.5-20.6; p = .01) and longer posttransfer LOS (rate ratio 1.7; 95% CI 1.1-2.6; p = .02).

CONCLUSION: MOID are common in ETs and are associated with increased mortality risk and posttransfer LOS. Diagnostic improvement strategies should be leveraged to support earlier recognition of clinical deterioration.

BACKGROUND: Antibiotics are prescribed to most pediatric intensive care unit (PICU) patients, but data describing indications and appropriateness of antibiotic orders in this population are lacking.

METHODS: We performed a multicenter point prevalence study that included children admitted to 10 geographically diverse PICUs over 4 study days in 2019. Antibiotic orders were reviewed for indication, and appropriateness was assessed using a standardized rubric.

RESULTS: Of 1462 patients admitted to participating PICUs, 843 (58%) had at least 1 antibiotic order. A total of 1277 antibiotic orders were reviewed. Common indications were empiric therapy for suspected bacterial infections without sepsis or septic shock (260 orders, 21%), nonoperative prophylaxis (164 orders, 13%), empiric therapy for sepsis or septic shock (155 orders, 12%), community-acquired pneumonia (CAP; 118 orders, 9%), and post-operative prophylaxis (94 orders, 8%). Appropriateness was assessed for 985 orders for which an evidence-based rubric for appropriateness could be created. Of these, 331 (34%) were classified as inappropriate. Indications with the most orders classified as inappropriate were empiric therapy for suspected bacterial infection without sepsis or septic shock (78 orders, 24%), sepsis or septic shock (55 orders, 17%), CAP (51 orders, 15%), ventilator-associated infections (47 orders, 14%), and post-operative prophylaxis (44 orders, 14%). The proportion of antibiotics classified as inappropriate varied across institutions (range, 19%-43%).

CONCLUSIONS: Most PICU patients receive antibiotics. Based on our study, we estimate that one-third of antibiotic orders are inappropriate. Improved antibiotic stewardship and research focused on strategies to optimize antibiotic use in critically ill children are needed.

OBJECTIVE: To conduct a process evaluation of a respiratory culture diagnostic stewardship intervention.

DESIGN: Mixed-methods study.

SETTING: Tertiary-care pediatric intensive care unit (PICU).

PARTICIPANTS: Critical care, infectious diseases, and pulmonary attending physicians and fellows; PICU nurse practitioners and hospitalist physicians; pediatric residents; and PICU nurses and respiratory therapists.

METHODS: This mixed-methods study was conducted concurrently with a diagnostic stewardship intervention to reduce the inappropriate collection of respiratory cultures in mechanically ventilated children. We quantified baseline respiratory culture utilization and indications for ordering using quantitative methods. Semistructured interviews informed by these data and the Consolidated Framework for Implementation Research (CFIR) were then performed, recorded, transcribed, and coded to identify salient themes. Finally, themes identified in these interviews were used to create a cross-sectional survey.

RESULTS: The number of cultures collected per day of service varied between attending physicians (range, 2.2-27 cultures per 100 days). In total, 14 interviews were performed, and 87 clinicians completed the survey (response rate, 47%) and 77 nurses or respiratory therapists completed the survey (response rate, 17%). Clinicians varied in their stated practices regarding culture ordering, and these differences both clustered by specialty and were associated with perceived utility of the respiratory culture. Furthermore, group "default" practices, fear, and hierarchy were drivers of culture orders. Barriers to standardization included fear of a missed diagnosis and tension between practice standardization and individual decision making.

CONCLUSIONS: We identified significant variation in utilization and perceptions of respiratory cultures as well as several key barriers to implementation of this diagnostic test stewardship intervention.

Improving Vancomycin Stewardship in Critically Ill Children.

2022

2022 Apr 01

1098-4275

<p><strong>BACKGROUND AND OBJECTIVES: </strong>Inappropriate vancomycin use is common in children's hospitals. We report a quality improvement (QI) intervention to reduce vancomycin use in our tertiary care PICU.</p>

<p><strong>METHODS: </strong>We retrospectively quantified the prevalence of infections caused by organisms requiring vancomycin therapy, including methicillin-resistant Staphylococcus aureus (MRSA), among patients with suspected bacterial infections. Guided by these data, we performed 3 QI interventions over a 3-year period, including (1) stakeholder education, (2) generation of a consensus-based guideline for empiric vancomycin use, and (3) implementation of this guideline through clinical decision support. Vancomycin use in days of therapy (DOT) per 1000 patient days was measured by using statistical process control charts. Balancing measures included frequency of bacteremia due to an organism requiring vancomycin not covered with empiric therapy, 30-day mortality, and cardiovascular, respiratory, and renal organ dysfunction.</p>

<p><strong>RESULTS: </strong>Among 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 (0.5%). During the 3-year 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). All balancing measures were unchanged, and all cases of MRSA bacteremia were treated empirically with vancomycin.</p>

<p><strong>CONCLUSION: </strong>Our interventions reduced overall vancomycin use in the PICU without evidence of harm. Provider education and consensus building surrounding indications for empiric vancomycin use were key strategies.</p>

<p><strong>BACKGROUND: </strong>In-hospital cardiac arrest is a rare event associated with significant morbidity and mortality. The ability to identify the ICU patients at risk for cardiac arrest could allow the clinical team to prepare staff and equipment in anticipation.</p>

<p><strong>METHODS: </strong>This pilot study was completed at a large tertiary care pediatric intensive care unit to determine the feasibility of a simple checklist of clinical variables to predict deterioration. The daily checklist assessed patient risk for critical deterioration defined as cardiac arrest or code bell activation within 24h of the checklist screen. The Phase I checklist was developed by expert consensus and evaluated to determine standard diagnostic test performance. A modified Phase II checklist was developed to prospectively test the feasibility and bedside provider "number needed to train".</p>

<p><strong>RESULTS: </strong>For identifying patients requiring code bell activation, both checklists demonstrated a sensitivity of 100% with specificity of 76.0% during Phase I and 97.7% during Phase II. The positive likelihood ratio improved from 4.2 to 43.7. For identifying patients that had a cardiac arrest within 24h, the Phase I and II checklists demonstrated a sensitivity of 100% with specificity again improving from 75.7% to 97.6%. There was an improved positive likelihood ratio from 4.1 in Phase I to 41.9 in Phase II, with improvement of "number needed to train" from 149 to 7.4 providers.</p>

<p><strong>CONCLUSIONS: </strong>A novel high-risk clinical indicators checklist is feasible and provides timely and accurate identification of the ICU patients at risk for cardiac arrest or code bell activation.</p>
