Readmission Diagnoses After Pediatric Severe Sepsis Hospitalization

Fish oil lipid emulsion compared with soybean oil lipid emulsion in pediatric patients with parenteral nutrition-associated cholestasis: A cost-effectiveness study

OBJECTIVES

Evidence indicates that, in pediatric patients with parenteral nutrition-associated cholestasis (PNAC), the use of a 100% fish oil lipid emulsion (FOLE) increased the likelihood of PNAC resolution and reduced the likelihood of liver transplantation compared with a 100% soybean oil lipid emulsion (SOLE). To evaluate the potential economic benefit, we conducted a cost-effectiveness analysis comparing FOLE with SOLE.

STUDY DESIGN

A discrete event simulation model evaluated cost-effectiveness by simulating clinical outcomes and estimating associated healthcare costs in pediatric patients with PNAC receiving parenteral nutrition (PN) with FOLE (1 g/kg) or SOLE (1.9 g/kg) over a time horizon of 6 years. Model inputs for clinical outcomes were derived from the integrated analysis of two US Phase 3 trials (NCT00910104 and NCT00738101). Cost estimates were estimated from the perspective of the US payer including the cost of PN, transplantation, and adverse events.

RESULTS

The total cost associated with FOLE was $69,847 USD vs $141,605 USD for SOLE. The cost reduction of $71,757 USD was attributable to the avoidance of liver transplantation (-15.7%) and reduction in adverse events (-4.8%). Life-years and the quality-adjusted life-years were increased with FOLE compared with SOLE (by 0.248 and 0.295, respectively).

CONCLUSION

By reducing the need for liver transplant and providing time to transition to full enteral nutrition, FOLE leads to cost-savings, compared with SOLE, in pediatric patients with PNAC in the perspective of the US payer. These findings support the use of FOLE in pediatric patients with PNAC who require PN.

Hospital readmission after surviving sepsis: A systematic review of readmission reasons and meta-analysis of readmission rates

PURPOSE

To review the evidence regarding hospital readmission diagnoses and analyse related readmission rates following a sepsis admission.

METHODS

Five databases, grey literature, and selected article reference lists were searched in May and June 2024. Included studies investigated sepsis survivor readmissions and reported readmission diagnoses and rates. Meta-analyses of readmission rates were performed.

RESULTS

After screening, 51 studies were included, with most studies (46/51; 90.2 %) investigating adult survivors. Infection or sepsis were reported as the most common readmission reason in 18 of the 21 studies investigating three or more readmission diagnoses in adults. Meta-analyses showed that 4.7 % (95 % CI: 3.1 to 6.5 %, PI: 0.3-13.4 %, n = 11 studies) of adult survivors readmitted to hospital with another sepsis diagnosis at 30 days, 8.1 % (95 % CI: 4.5 to 12.7 %, PI: <0.1-29.0 %, n = 7) at 90 days, and 16.4 % (95 % CI: 11.3 to 22.2 %, PI: <0.1-96.3 %, n = 3) at one year. At 30 days 3.5 % (95 % CI: 2.2-5.0 %, PI: 0.3-10.0 %, n = 7) of adult survivors readmitted to hospital with a cardiovascular disease diagnosis.

CONCLUSIONS

Infection and sepsis are frequent readmission diagnoses for sepsis survivors, with one in 21 adult survivors readmitted for sepsis at 30-days. PROSPERO registration: CRD42023455851.

Frequency of and Risk Factors for Increased Healthcare Utilization After Pediatric Sepsis Hospitalization

OBJECTIVES

To determine the frequency of and risk factors for increased post-sepsis healthcare utilization compared with pre-sepsis healthcare utilization.

DESIGN

Retrospective observational cohort study.

SETTING

Years 2016-2019 MarketScan Commercial and Medicaid Database.

PATIENTS

Children (0-18 yr) with sepsis treated in a U.S. hospital.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We measured the frequency of and risk factors for increased healthcare utilization in the 90 days post- vs. pre-sepsis hospitalization. We defined increased healthcare utilization as an increase of at least 3 days in the 90 days post-hospitalization compared with the 90 days pre-hospitalization based on outpatient, emergency department, and inpatient hospitalization. We identified 2801 patients hospitalized for sepsis, of whom 865 (30.9%) had increased healthcare utilization post-sepsis, with a median (interquartile range [IQR]) of 3 days (1-6 d) total in the 90 days pre-sepsis and 10 days (IQR, 6-21 d) total in the 90 days post-sepsis ( p < 0.001). In multivariable models, the odds of increased healthcare use were higher for children with longer lengths of hospitalization (> 30 d adjusted odds ratio [aOR], 4.35; 95% CI, 2.99-6.32) and children with preexisting complex chronic conditions, specifically renal (aOR, 1.47; 95% CI, 1.02-2.12), hematologic/immunologic (aOR, 1.34; 95% CI, 1.03-1.74), metabolic (aOR, 1.39; 95% CI, 1.08-1.79), and malignancy (aOR, 1.89; 95% CI, 1.38-2.59).

CONCLUSIONS

In this nationally representative cohort of children who survived sepsis hospitalization in the United States, nearly one in three had increased healthcare utilization in the 90 days after discharge. Children with hospitalizations longer than 30 days and complex chronic conditions were more likely to experience increased healthcare utilization.

Trajectory and Risk Factors of Persistent Decline in Health-Related Quality of Life after Septic Shock in Children with Preexisting Neurologic Disability

Preexisting neurologic disability is common among children with septic shock. Life After Pediatric Sepsis Evaluation (LAPSE) was a multicenter cohort study that evaluated health-related quality of life (HRQL) in children with community-acquired septic shock. In this secondary analysis of LAPSE, we described the burden, trajectory, and risk factors for reduced HRQL in children with preexisting neurologic disability. Children (1 month-18 years) with community-acquired septic shock were evaluated for HRQL at baseline (reflecting prehospitalization status), day 7 and 28, and month 3, 6, and 12 following admission using the Pediatric Quality of Life Inventory or the Stein-Jessop Functional Status Scale. HRQL was expressed as a percentage of baseline scores. Of 365 evaluable children, 133 (36%) had preexisting neurologic disability. Neurologically disabled children had less decline in HRQL at day 7 (median -15% [interquartile range IQR: -38, 8] vs. -22% [-51, -3], p  = 0.005) and day 28 (4% [-16, 22] vs. -11% [-37, 7], p  < 0.001) than those without neurologic disability, and there was no difference in the extent of decline at month 3 ( p  = 0.241). Using multivariable modeling, higher baseline HRQL (odds ratio [OR] = 1.04 [95% confidence interval [CI]: 1.00, 1.08], p  = 0.027) and acute renal dysfunction (OR = 1.08 [1.02, 1.16], p  = 0.007) were associated with HRQL less than 90% of baseline at month 3 in neurologically disabled children who survived. Children with preexisting neurologic disability recover to baseline HRQL after septic shock sooner than those without neurologic disability. Higher baseline HRQL and acute renal dysfunction are risk factors for reduced HRQL in neurologically disabled children who survive sepsis.

Pediatric Sepsis Diagnosis, Management, and Sub-phenotypes

Sepsis and septic shock are major causes of morbidity, mortality, and health care costs for children worldwide, including >3 million deaths annually and, among survivors, risk for new or worsening functional impairments, including reduced quality of life, new respiratory, nutritional, or technological assistance, and recurrent severe infections. Advances in understanding sepsis pathophysiology highlight a need to update the definition and diagnostic criteria for pediatric sepsis and septic shock, whereas new data support an increasing role for automated screening algorithms and biomarker combinations to assist earlier recognition. Once sepsis or septic shock is suspected, attention to prompt initiation of broad-spectrum empiric antimicrobial therapy, fluid resuscitation, and vasoactive medications remain key components to initial management with several new and ongoing studies offering new insights into how to optimize this approach. Ultimately, a key goal is for screening to encompass as many children as possible at risk for sepsis and trigger early treatment without increasing unnecessary broad-spectrum antibiotics and preventable hospitalizations. Although the role for adjunctive treatment with corticosteroids and other metabolic therapies remains incompletely defined, ongoing studies will soon offer updated guidance for optimal use. Finally, we are increasingly moving toward an era in which precision therapeutics will bring novel strategies to improve outcomes, especially for the subset of children with sepsis-induced multiple organ dysfunction syndrome and sepsis subphenotypes for whom antibiotics, fluid, vasoactive medications, and supportive care remain insufficient.

Frequency of and Risk Factors Associated With Hospital Readmission After Sepsis

OBJECTIVES

Although children who survive sepsis are at risk for readmission, identification of patient-level variables associated with readmission has been limited by administrative datasets. We determined frequency and cause of readmission within 90 days of discharge and identified patient-level variables associated with readmission using a large, electronic health record-based registry.

METHODS

This retrospective observational study included 3464 patients treated for sepsis or septic shock between January 2011 and December 2018 who survived to discharge at a single academic children's hospital. We determined frequency and cause of readmission through 90 days post-discharge and identified patient-level variables associated with readmission. Readmission was defined as inpatient treatment within 90 days post-discharge from a prior sepsis hospitalization. Outcomes were frequency of and reasons for 7-, 30-, and 90-day (primary) readmission. Patient variables were tested for independent associations with readmission using multivariable logistic regression.

RESULTS

Following index sepsis hospitalization, frequency of readmission at 7, 30, and 90 days was 7% (95% confidence interval 6%-8%), 20% (18%-21%), and 33% (31%-34%). Variables independently associated with 90-day readmission were age ≤ 1 year, chronic comorbid conditions, lower hemoglobin and higher blood urea nitrogen at sepsis recognition, and persistently low white blood cell count ≤ 2 thous/µL. These variables explained only a small proportion of overall risk (pseudo-R2 range 0.05-0.13) and had moderate predictive validity (area under the receiver operating curve range 0.67-0.72) for readmission.

CONCLUSIONS

Children who survive sepsis were frequently readmitted, most often for infections. Risk for readmission was only partly indicated by patient-level variables.

Characteristics and Outcomes of Young Adult Patients with Severe Sepsis Admitted to Pediatric Intensive Care Units Versus Medical/Surgical Intensive Care Units

Purpose: Young adults receive severe sepsis treatment across pediatric and adult care settings. However, little is known about young adult sepsis outcome differences in pediatric versus adult hospital settings. Material and Methods: Using Truven MarketScan database from 2010-2015, we compared in-hospital mortality and hospital length of stay in young adults ages 18-26 treated for severe sepsis in Pediatric Intensive Care Units (PICUs) versus Medical ICUs (MICUs)/Surgical ICUs (SICUs) using logistic regression models and accelerated time failure models, respectively. Comorbidities were identified using Complex Chronic Conditions (CCC) and Charlson Comorbidity Index (CCI). Results: Of the 18 900 young adults hospitalized with severe sepsis, 163 (0.9%) were treated in the PICU and 952 (5.0%) in the MICU/SICU. PICU patients were more likely to have a comorbid condition compared to MICU/SICU patients. Compared to PICU patients, MICU/SICU patients had a lower odds of in-hospital mortality after adjusting for age, sex, Medicaid status, and comorbidities (adjusting for CCC, odds ratio [OR]: 0.50, 95% CI 0.29-0.89; adjusting for CCI, OR: 0.51, 95% CI 0.29-0.94). There was no difference in adjusted length of stay for young adults with severe sepsis (adjusting for CCC, Event Time Ratio [ETR]: 1.14, 95% CI 0.94-1.38; adjusting for CCI, ETR: 1.09, 95% CI 0.90-1.33). Conclusions: Young adults with severe sepsis experience higher adjusted odds of mortality when treated in PICUs versus MICU/SICUs. However, there was no difference in length of stay. Variation in mortality is likely due to significant differences in the patient populations, including comorbidity status.

Children with severe sepsis: relationship between community level income and morbidity and mortality

BACKGROUND

Health disparities surrounding pediatric severe sepsis outcomes remains unclear. We aimed to measure the relationship between indicators of socioeconomic status and mortality, hospital length of stay (LOS), and readmission rates among children hospitalized with severe sepsis.

METHODS

Children 0-18 years old, hospitalized with severe sepsis in the Nationwide Readmissions Database (2016-2018) were included. The primary exposure was median household income by ZIP Code of residence, divided into quartiles.

RESULTS

We identified 15,214 index pediatric severe sepsis hospitalizations. There was no difference in hospital mortality rate or readmission rate across income quartiles. Among survivors, patients in Q1 (lowest income) had a 2 day longer LOS compared to those in Q4 (Median 10 days [IQR 4-21] vs 8 days [IQR 4-18]; p < 0.0001). However, there was no difference after adjusting for multiple covariates.

CONCLUSIONS

Children living in Q1 had a 2 day longer LOS versus their peers in Q4. This was not significant on multivariable analysis, suggesting income quartile is not driving this difference. As pediatric severe sepsis remains an important source of morbidity and mortality in critically ill children, more sensitive metrics of socioeconomic status may better elucidate any disparities.

IMPACT

Children with severe sepsis living in the lowest income ZIP Codes may have longer hospital stays compared to peers in higher income communities. More precise metrics of socioeconomic status are needed to better understand health disparities in pediatric severe sepsis.

Unplanned Admissions, Emergency Department Visits, and Epilepsy After Critical Neurological Illness Requiring Prolonged Mechanical Ventilation in Children

Background and Purpose

Long-term outcomes after pediatric neurocritical illness are poorly characterized. This study aims to characterize the frequency and risk factors for post-discharge unplanned health resource use in a pediatric neurocritical care population using insurance claims data.

Methods

Retrospective cohort study evaluating children who survived a hospitalization for an acute neurologic illness or injury requiring mechanical ventilation for >72 hours and had insurance eligibility in Colorado's All Payers Claims database. Insurance claims identified unplanned readmissions and emergency department [ED] visits during the post-discharge year. For patients without pre-existing epilepsy/seizures, we evaluated for post-ICU epilepsy identified by claim(s) for a maintenance anti-seizure medication during months 6-12 post-discharge. Multivariable logistic regression identified factors associated with each outcome.

Results

101 children, median age 3.7 years (interquartile range (IQR) .4-11.9), admitted for trauma (57%), hypoxic-ischemic injury (17%) and seizures (15%). During the post-discharge year, 4 (4%) patients died, 26 (26%) were readmitted, and 48 (48%) had an ED visit. Having a pre-existing complex chronic condition was independently associated with readmission and emergency department visit. Admission for trauma was protective against readmission. Of those without pre-existing seizures (n = 86), 25 (29%) developed post-ICU epilepsy. Acute seizures during admission and prolonged ICU stays were independently associated with post-ICU epilepsy.

Conclusions

Survivors of pediatric neurocritical illness are at risk of unplanned healthcare use and post-ICU epilepsy. Critical illness risk factors including prolonged ICU stay and acute seizures may identify cohorts for targeted follow up or interventions to prevent unplanned healthcare use and post-ICU epilepsy.

New and Progressive Medical Conditions After Pediatric Sepsis Hospitalization Requiring Critical Care

Importance

Children commonly experience physical, cognitive, or emotional sequelae after sepsis. However, little is known about the development or progression of medical conditions after pediatric sepsis.

Objective

To quantify the development and progression of 4 common conditions in the 6 months after sepsis and to assess whether they differed after hospitalization for sepsis vs nonsepsis among critically ill children.

Design, Setting, and Participants

This cohort study of 101 511 children (<19 years) with sepsis or nonsepsis hospitalization used a national administrative claims database (January 1, 2010, to June 30, 2018). Data management and analysis were conducted from April 1, 2020, to July 7, 2022.

Exposures

Intensive care unit hospitalization for sepsis vs all-cause intensive care unit hospitalizations, excluding sepsis.

Main Outcomes and Measures

Primary outcomes were the development of 4 target conditions (chronic respiratory failure, seizure disorder, supplemental nutritional dependence, and chronic kidney disease) within 6 months of hospital discharge. Secondary outcomes were the progression of the 4 target conditions among children with the condition before hospitalization. Outcomes were identified via diagnostic and procedural codes, durable medical equipment codes, and prescription medications. Differences in the development and the progression of conditions between pediatric patients with sepsis and pediatric patients with nonsepsis who survived intensive care unit hospitalization were assessed using logistic regression with matching weights.

Results

A total of 5150 survivors of pediatric sepsis and 96 361 survivors of nonsepsis intensive care unit hospitalizations were identified; 2593 (50.3%) were female. The median age was 9.5 years (IQR, 3-15 years) in the sepsis cohort and 7 years (IQR, 2-13 years) in the nonsepsis cohort. Of the 5150 sepsis survivors, 670 (13.0%) developed a new target condition, and 385 of 1834 (21.0%) with a preexisting target condition had disease progression. A total of 998 of the 5150 survivors (19.4%) had development and/or progression of at least 1 condition. New conditions were more common among sepsis vs nonsepsis hospitalizations (new chronic respiratory failure: 4.6% vs 1.9%; odds ratio [OR], 2.54 [95% CI, 2.19-2.94]; new supplemental nutritional dependence: 7.9% vs 2.7%; OR, 3.17 [95% CI, 2.80-3.59]; and new chronic kidney disease: 1.1% vs 0.6%; OR, 1.65 [95% CI, 1.25-2.19]). New seizure disorder was less common (4.6% vs 6.0%; OR, 0.77 [95% CI, 0.66-0.89]). Progressive supplemental nutritional dependence was more common (1.5% vs 0.5%; OR, 2.95 [95% CI, 1.60-5.42]), progressive epilepsy was less common (33.7% vs 40.6%; OR, 0.74 [95% CI, 0.65-0.86]), and progressive respiratory failure (4.4% vs 3.3%; OR, 1.35 [95% CI, 0.89-2.04]) and progressive chronic kidney disease (7.9% vs 9.2%; OR, 0.84 [95% CI, 0.18-3.91]) were similar among survivors of sepsis vs nonsepsis admitted to an intensive care unit.

Conclusions and Relevance

In this national cohort of critically ill children who survived sepsis, 1 in 5 developed or had progression of a condition of interest after sepsis hospitalization, suggesting survivors of pediatric sepsis may benefit from structured follow-up to identify and treat new or worsening medical comorbid conditions.

Health Resource Use in Survivors of Pediatric Septic Shock in the United States

OBJECTIVES

To evaluate postdischarge health resource use in pediatric survivors of septic shock and determine patient and hospitalization factors associated with health resource use.

DESIGN

Secondary analyses of a multicenter prospective observational cohort study.

SETTING

Twelve academic PICUs.

PATIENTS

Children greater than or equal to 1 month and less than 18 years old hospitalized for community-acquired septic shock who survived to 1 year.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

For 308/338 patients (91%) with baseline and greater than or equal to one postdischarge survey, we evaluated readmission, emergency department (ED) visits, new medication class, and new device class use during the year after sepsis. Using negative binomial regression with bidirectional stepwise selection, we identified factors associated with each outcome. Median age was 7 years (interquartile range, 2-13), 157 (51%) had a chronic condition, and nearly all patients had insurance (private [n = 135; 44%] or government [n = 157; 51%]). During the year after sepsis, 128 patients (42%) were readmitted, 145 (47%) had an ED visit, 156 (51%) started a new medication class, and 102 (33%) instituted a new device class. Having a complex chronic condition was independently associated with readmission and ED visit. Documented infection and higher sum of Pediatric Logistic Organ Dysfunction--2 hematologic score were associated with readmission, whereas younger age and having a noncomplex chronic condition were associated with ED visit. Factors associated with new medication class use were private insurance, neurologic insult, and longer PICU stays. Factors associated with new device class use were preadmission chemotherapy or radiotherapy, presepsis Functional Status Scale score, and ventilation duration greater than or equal to 10 days. Of patients who had a new medication or device class, most had a readmission (56% and 61%) or ED visit (62% and 67%).

CONCLUSIONS

Children with septic shock represent a high-risk cohort with high-resource needs after discharge. Interventions and targeted outcomes to mitigate postdischarge resource use may differ based on patients' preexisting conditions.

Analyzing Relationships Between Economic and Neighborhood-Related Social Determinants of Health and Intensive Care Unit Length of Stay for Critically Ill Children With Medical Complexity Presenting With Severe Sepsis

Objectives

Of the Social Determinants of Health (SDoH), we evaluated socioeconomic and neighborhood-related factors which may affect children with medical complexity (CMC) admitted to a Pediatric Intensive Care Unit (PICU) in Shelby County, Tennessee with severe sepsis and their association with PICU length of stay (LOS). We hypothesized that census tract-level socioeconomic and neighborhood factors were associated with prolonged PICU LOS in CMC admitted with severe sepsis in the underserved community.

Methods

This single-center retrospective observational study included CMC living in Shelby County, Tennessee admitted to the ICU with severe sepsis over an 18-month period. Severe sepsis CMC patients were identified using an existing algorithm incorporated into the electronic medical record at a freestanding children's hospital. SDoH information was collected and analyzed using patient records and publicly available census-tract level data, with ICU length of stay as the primary outcome.

Results

83 encounters representing 73 patients were included in the analysis. The median PICU LOS was 9.04 days (IQR 3.99–20.35). The population was 53% male with a median age of 4.1 years (IQR 1.96–12.02). There were 57 Black/African American patients (68.7%) and 85.5% had public insurance. Based on census tract-level data, about half (49.4%) of the CMC severe sepsis population lived in census tracts classified as suffering from high social vulnerability. There were no statistically significant relationships between any socioeconomic and neighborhood level factors and PICU LOS.

Conclusion

Pediatric CMC severe sepsis patients admitted to the PICU do not have prolonged lengths of ICU stay related to socioeconomic and neighborhood-level SDoH at our center. A larger sample with the use of individual-level screening would need to be evaluated for associations between social determinants of health and PICU outcomes of these patients.

Parent post-traumatic growth after a child's critical illness

OBJECTIVE

Post-traumatic growth is the experience of a positive change after a traumatic event. Our objective is to characterize the factors associated with post-traumatic growth in parents after a child's pediatric intensive care unit (PICU) admission.

STUDY DESIGN

A cross-sectional survey study examining post-traumatic growth and select independent variables in parents 1 year after a child's ≥72 h PICU admission for an acute illness or injury. The study was completed in parents of children discharge alive from a tertiary care PICU from January 1, 2017 to December 31, 2017. A mixed-effects linear regression model was built to evaluate the association of post-traumatic stress, anxiety, depression, resiliency, family function, and child function with post-traumatic growth.

RESULTS

Eighty-two parents of 52 children discharged alive in 2017 completed the survey. Fifty-two percent were ≥35 years and 64.3% were mothers. Median age of their children was 2.8 years (IQR 0.5-11.3) with a median hospital stay of 12 Days (IQR 6-20). Moderate-to-high levels of post-traumatic growth occurred in 67.1% of parents. Increased hospital length of stay (β Coeff 0.85; p = 0.004, 95% CI 0.27, 1.43) and parent post-traumatic stress symptoms (β Coeff 1.04; p = 0.006, 95% CI 0.29, 1.78) were associated with increased post-traumatic growth, and increased parent depression symptoms (β Coeff -1.96; p = 0.015; 95% CI -3.54, -0.38) with decreased post-traumatic growth.

CONCLUSION

Longer child hospital stays and increased parent post-traumatic stress symptoms were associated with increased post-traumatic growth, while increased depression was associated with less post-traumatic growth. The impact of future PICU parent psychosocial interventions on parents may be best assessed using a dual outcome focused on both reducing negative mental health symptoms while concurrently promoting skills to facilitate parent adaptation and post-traumatic growth.

What's the Cost? Measuring the Economic Impact of Pediatric Sepsis

Sepsis, life-threatening organ dysfunction secondary to infection, hospitalizes nearly 75,000 children each year in the United States. Most children survive sepsis. However, there is increasing recognition of the longer-term consequences of pediatric sepsis hospitalization on both the child and their family, including medical, psychosocial, and financial impacts. Here, we describe family spillover effects (the impact of illness on caregivers) of pediatric sepsis, why measurement of family spillover effects is important, and the ways in which family spillover effects can be measured.

Implementation of a Follow-Up System for Pediatric Sepsis Survivors in a Large Academic Pediatric Intensive Care Unit

Background: Survivors of pediatric sepsis often develop new morbidities and deterioration in quality of life after sepsis, leading to a need for improved follow-up for children who survive sepsis. Objective: To implement a follow-up system for pediatric sepsis survivors in a pediatric health system. Methods: We performed a retrospective case series of patients treated for sepsis from October 2018 through October 2019 in a pediatric intensive care unit in a quaternary children's hospital, and describe implementation of a follow-up system for sepsis survivors. Program planning started in 2017 with multidisciplinary meetings including physical, occupational, and speech therapists, teachers, neuropsychologists, and coordinators from other survivorship programs (neonatology, stroke, and oncology). In 2018, a workshop was held to consult with local and national experts. The Pediatric Sepsis Survivorship Program launched in October 2018 led by a nurse coordinator who met with families to educate about sepsis and offer post-discharge follow-up. Patients with high pre-existing medical complexity or established subspecialty care were referred for follow-up through existing care coordination or subspecialty services plus guidance to monitor for post-sepsis morbidity. For patients with low-moderate medical complexity, the nurse coordinator administered a telephone-based health-assessment 2-3 months after discharge to screen for new physical or psychosocial morbidity. Patients flagged with concerns were referred to their primary physician and/or to expedited neuropsychological evaluation to utilize existing medical services. Results: Of 80 sepsis patients, 10 died, 20 were referred to care coordination by the program, and 13 had subspecialty follow-up. Five patients were followed in different health systems, four were adults not appropriate for existing follow-up programs, four remained hospitalized, and four were missed due to short stay or unavailable caregivers. The remaining 20 patients were scheduled for follow-up with the Pediatric Sepsis Program. Nine patients completed the telephone assessment. Four patients were receiving new physical or occupational therapy, and one patient was referred for neuropsychology evaluation due to new difficulties with attention, behavior, and completion of school tasks. Conclusions: Implementation of an efficient, low-cost pediatric sepsis survivorship program was successful by utilizing existing systems of care, when available, and filling a follow-up gap in screening for select patients.

Autonomic Nervous System Dysfunction Is Associated With Re-hospitalization in Pediatric Septic Shock Survivors

Objective: Re-hospitalization after sepsis can lead to impaired quality of life. Predictors of re-hospitalization could help identify sepsis survivors who may benefit from targeted interventions. Our goal was to determine whether low heart rate variability (HRV), a measure of autonomic nervous system dysfunction, is associated with re-hospitalization in pediatric septic shock survivors. Materials and Methods: This was a retrospective, observational cohort study of patients admitted between 6/2012 and 10/2020 at a single institution. Patients admitted to the pediatric intensive care unit with septic shock who had continuous heart rate data available from the bedside monitors and survived their hospitalization were included. HRV was measured using age-normalized z-scores of the integer HRV (HRVi), which is the standard deviation of the heart rate sampled every 1 s over 5 consecutive minutes. The 24-h median HRVi was assessed on two different days: the last 24 h of PICU admission ("last HRVi") and the 24-h period with the lowest median HRVi ("lowest HRVi"). The change between the lowest and last HRVi was termed "delta HRVi." The primary outcome was re-hospitalization within 1 year of discharge, including both emergency department encounters and hospital readmission, with sensitivity analyses at 30 and 90 days. Kruskal-Wallis, logistic regression, and Poisson regression evaluated the association between HRVi and re-hospitalizations and adjusted for potential confounders. Results: Of the 463 patients who met inclusion criteria, 306 (66%) were re-hospitalized, including 270 readmissions (58%). The last HRVi was significantly lower among re-hospitalized patients compared to those who were not (p = 0.02). There was no difference in the lowest HRVi, but patients who were re-hospitalized showed a smaller recovery in their delta HRVi compared to those who were not re-hospitalized (p = 0.02). This association remained significant after adjusting for potential confounders. In the sensitivity analysis, a smaller recovery in delta HRVi was consistently associated with a higher likelihood of re-hospitalization. Conclusion: In pediatric septic shock survivors, a smaller recovery in HRV during the index admission is significantly associated with re-hospitalization. This continuous physiologic measure could potentially be used as a predictor of patients at risk for re-hospitalization and lower health-related quality of life.

Parental Mental Health Care After Their Child's Pediatric Intensive Care Hospitalization

OBJECTIVES

Post-traumatic stress disorder, depression, and anxiety have all been found in parents of PICU survivors. How these research findings translate to actual use of mental health services by parents remains unknown.

DESIGN

Retrospective observational cohort study.

SETTING

Insurance claims data from 2006 to 2013 obtained from the IBM MarketScan Commercial Database.

PATIENTS

Parents of PICU survivors.

INTERVENTIONS

We examined rates of: 1) mental health diagnoses, 2) outpatient mental health visits, and 3) prescriptions for antidepressants and anxiolytics among parents, 6 months before and 6 months after their child's PICU admission, using each parent as their own control.

MEASUREMENTS AND MAIN RESULTS

Of the 95,070 parents identified, 9.5% received a new mental health diagnosis in the 6 months after their child's PICU hospitalization, which represented a 110% increase from pre-PICU rates. A smaller proportion of parents were given new prescriptions for antidepressants (3.4%) and anxiolytics (3.9%) in the 6 months after their child's PICU hospitalization. Mothers were twice as likely to receive a new mental health diagnosis and be taking a new medication than fathers in the post-PICU period. The parental diagnosis of acute stress disorder or post-traumatic stress disorder increased by 87% from the pre-PICU to the post-PICU period.

CONCLUSIONS

After their child's PICU hospitalization, the proportion of parents with a new mental health diagnosis nearly doubled. Mothers were at nearly twice the risk of receiving a new mental health diagnosis and receiving a new mental health medication compared with fathers. The proportion of parents receiving mental healthcare is much lower than the proportion reporting mental health symptoms in long-term outcomes studies. Whether this indicates a gap in healthcare delivery for parents with mental health symptoms remains unknown.

Comparison of Outpatient Health Care Use Before and After Pediatric Severe Sepsis

This cohort study examined the number and type of outpatient health visits before and after hospitalization for pediatric severe sepsis.

New Medical Device Acquisition During Pediatric Severe Sepsis Hospitalizations

OBJECTIVES

Severe sepsis is a significant cause of healthcare utilization and morbidity among pediatric patients. However, little is known about how commonly survivors acquire new medical devices during pediatric severe sepsis hospitalization. We sought to determine the rate of new device acquisition (specifically, tracheostomy placement, gastrostomy tube placement, vascular access devices, ostomy procedures, and amputation) among children surviving hospitalizations with severe sepsis. For contextualization, we compare this to rates of new device acquisition among three comparison cohorts: 1) survivors of all-cause pediatric hospitalizations; 2) matched survivors of nonsepsis infection hospitalizations; and 3) matched survivors of all-cause nonsepsis hospitalization with similar organ dysfunction.

DESIGN

Observational cohort study.

SETTING

Nationwide Readmission Database (2016), including all-payer hospitalizations from 27 states.

PATIENTS

Eighteen-thousand two-hundred ten pediatric severe sepsis hospitalizations; 532,738 all-cause pediatric hospitalizations; 16,173 age- and sex-matched nonsepsis infection hospitalizations; 15,025 organ dysfunction matched all-cause nonsepsis hospitalizations; and all with live discharge.

MEASUREMENTS AND MAIN RESULTS

Among 18,210 pediatric severe sepsis hospitalizations, 1,024 (5.6%) underwent device placement. Specifically, 3.5% had new gastrostomy, 3.1% new tracheostomy, 0.6% new vascular access devices, 0.4% new ostomy procedures, and 0.1% amputations. One-hundred forty hospitalizations (0.8%) included two or more new devices. After applying the Nationwide Readmissions Database sampling weights, there were 55,624 pediatric severe sepsis hospitalizations and 1,585,194 all-cause nonsepsis hospitalizations with live discharge in 2016. Compared to all-cause pediatric hospitalizations, severe sepsis hospitalizations were eight-fold more likely to involve new device acquisition (6.4% vs 0.8%; p < 0.001). New device acquisition was also higher in severe sepsis hospitalizations compared with matched nonsepsis infection hospitalizations (5.1% vs 1.2%; p < 0.01) and matched all-cause hospitalizations with similar organ dysfunction (4.7% vs 2.8%; p < 0.001).

CONCLUSIONS

In this nationwide, all-payer cohort of U.S. pediatric severe sepsis hospitalizations, one in 20 children surviving severe sepsis experienced new device acquisition. The procedure rate was nearly eight-fold higher than all-cause, nonsepsis pediatric hospitalizations, and four-fold higher than matched nonsepsis infection hospitalizations.

Cost of Pediatric Severe Sepsis Hospitalizations

This study examines the increasing costs of pediatric hospitalizations for cases of severe sepsis using the 2016 Nationwide Readmissions Database.
