Exploring Relations Between Unique Patient Characteristics and Virtual Reality Immersion Level on Anxiety and Pain in Patients Undergoing Venipuncture: Secondary Analysis of a Randomized Control Trial.

BACKGROUND: Virtual reality (VR) is a well-researched digital intervention that has been used for managing acute pain and anxiety in pediatric patients undergoing various medical procedures. This study focuses on investigating the role of unique patient characteristics and VR immersion level on the effectiveness of VR for managing pediatric pain and anxiety during venipuncture. OBJECTIVE: The purpose of this study is to determine how specific patient characteristics and level of immersion during a VR intervention impact anxiety and pain levels for pediatric patients undergoing venipuncture procedures. METHODS: This study is a secondary data analysis of 2 combined, previously published randomized control trials on 252 pediatric patients aged 10-21 years observed at Children's Hospital Los Angeles from April 12, 2017, to July 24, 2019. One randomized clinical trial was conducted in 3 clinical environments examining peripheral intravenous catheter placement (radiology and an infusion center) and blood draw (phlebotomy). Conditional process analysis was used to conduct moderation and mediation analyses to assess the impact of immersion level during the VR intervention. RESULTS: Significant moderation was found between the level of immersion and anxiety sensitivity when predicting postprocedural anxiety (P=.01). Patients exhibiting the highest anxiety sensitivity within the standard of care yielded a 1.9 (95% CI 0.9-2.8; P<.001)-point elevation in postprocedural anxiety relative to individuals with high immersion levels. No other significant factors were found to mediate or moderate the effect of immersion on either postprocedural anxiety or pain. CONCLUSIONS: VR is most effective for patients with higher anxiety sensitivity who report feeling highly immersed. Age, location of the procedure, and gender of the patient were not found to significantly impact VR's success in managing levels of postprocedural pain or anxiety, suggesting that immersive VR may be a beneficial intervention for a broad pediatric population.

Noninvasive Surrogate for Physiologic Dead Space Using the Carbon Dioxide Ventilatory Equivalent: Testing in a Single-Center Cohort, 2017-2023.

OBJECTIVES: We sought to evaluate the association between the carbon dioxide ( co2 ) ventilatory equivalent (VEq co2 = minute ventilation/volume of co2 produced per min), a marker of dead space that does not require a blood gas measurement, and mortality risk. We compared the strength of this association to that of physiologic dead space fraction (V D /V t = [Pa co2 -mixed-expired P co2 ]/Pa co2 ) as well as to other commonly used markers of dead space (i.e., the end-tidal alveolar dead space fraction [AVDSf = (Pa co2 -end-tidal P co2 )/Pa co2 ], and ventilatory ratio [VR = (minute ventilation × Pa co2 )/(age-adjusted predicted minute ventilation × 37.5)]). DESIGN: Retrospective cohort data, 2017-2023. SETTING: Quaternary PICU. PATIENTS: One hundred thirty-one children with acute respiratory distress syndrome. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: All dead space markers were calculated at the same 1-minute timepoint for each patient within the first 72 hours of using invasive mechanical ventilation. The 131 children had a median (interquartile range, IQR) age of 5.8 (IQR 1.4, 12.6) years, oxygenation index (OI) of 7.5 (IQR 4.6, 14.3), V D /V t of 0.47 (IQR 0.38, 0.61), and mortality was 17.6% (23/131). Higher VEq co2 ( p = 0.003), V D /V t ( p = 0.002), and VR ( p = 0.013) were all associated with greater odds of mortality in multivariable models adjusting for OI, immunosuppressive comorbidity, and overall severity of illness. We failed to identify an association between AVDSf and mortality in the multivariable modeling. Similarly, we also failed to identify an association between OI and mortality after controlling for any dead space marker in the modeling. For the 28-day ventilator-free days outcome, we failed to identify an association between V D /V t and the dead space markers in multivariable modeling, although OI was significant. CONCLUSIONS: VEq co2 performs similarly to V D /V t and other surrogate dead space markers, is independently associated with mortality risk, and may be a reasonable noninvasive surrogate for V D /V t .

Caregiver Satisfaction with Medical Providers' Communication: Comparison Between Spanish-Speaking Caregivers with Limited English Proficiency (LEP) and Caregivers Who Are English-Proficient (EP).

OBJECTIVES: Barriers to communication have been observed with patients and families who prefer a language other than English for medical conversations, referred to as individuals with limited English proficiency (LEP). We used the pediatric Family Satisfaction with ICU 24R (FS-ICU) survey to assess communication satisfaction for English-proficient (EP) and Spanish-speaking LEP caregivers. We added additional questions related to attendance at morning rounds, frequency of provider updates, interpreter use, and general satisfaction with communication. METHODS: This was a single-center, prospective, observational cohort study in the pediatric intensive care unit (PICU) and cardiothoracic intensive care unit (CICU) of a tertiary, academic, free-standing children's hospital. Caregivers of children < 18 years old admitted for at least 48 h to the PICU or CICU between June and September 2022 were eligible for enrollment. MEASUREMENTS AND MAIN RESULTS: 24 LEP and 74 EP caregivers completed the survey questions. The LEP group had lower household income and education levels and higher incidence of public insurance. FS-ICU scores for both LEP and EP caregivers suggested high satisfaction, without significant difference between the groups. However, qualitative analysis revealed dissatisfaction for LEP caregivers related to information, inclusion, and language barriers. EP caregivers had more positive references to information and emotional connection but indicated dissatisfaction around consistency and responsiveness. 18% of LEP caregivers reported regularly attending rounds, versus 67% of the EP group (p value < .001). 39% of LEP versus 52% of EP caregivers reported multiple daily updates, although the difference was not statistically significant. 29% of LEP respondents reported nonfluent MD/NPs using an interpreter never, rarely, or some of the time. CONCLUSIONS: There was no difference in satisfaction scores between LEP and EP caregivers. LEP caregivers had lower socioeconomic status based on public insurance and reported income and education level. Qualitative data allowed more nuanced understanding of communication satisfaction, which correlated with LEP caregivers' reported lower attendance at morning rounds, inconsistent interpreter use, and a trend toward less frequent provider updates.

Factors associated with family decision-making after pediatric out-of-hospital cardiac arrest.

AIM: This study aims to identify demographic factors, area-based social determinants of health (SDOH), and clinical features associated with medical decision-making after pediatric out-of-hospital cardiac arrest (OHCA). METHODS: This is a retrospective, exploratory, descriptive analysis of patients < 18 years old admitted to the pediatric intensive care unit (ICU) after OHCA from 2011 to 2022 (n = 217) at an urban tertiary care, free-standing children's hospital. Outcomes of interest included: (1) whether a new advance care plan (ACP) (defined as a written advance directive including do not resuscitate and/or do not intubate) was ordered during hospitalization, and (2) whether the patient was discharged with new medical technology (defined as tracheostomy and/or feeding tube). Logistic regression models identified features associated with these outcomes. RESULTS: Of the 217 patients, 78 patients (36%) had a new ACP placed during their admission. Of the survivors, 26% (27/102) were discharged home with new medical technology. Factors associated with ACP were greater change in Pediatric Cerebral Performance Category (PCPC) score (aOR = 1.49, 95% CI [1.28-1.73], p-value < 0.001) and palliative care consultation (aOR = 2.39, 95% CI [1.16-4.89], p-value 0.018). Factors associated with new medical technology were lower change in PCPC score (aOR = 0.76, 95% C.I. [0.61-0.95], p-value = 0.015) and palliative care consultation (aOR = 7.07, 95% CI [3.01-16.60], p-value < 0.001). There were no associations between area-based SDOH and outcomes. CONCLUSIONS: Understanding factors associated with decision-making related to ACP after OHCA is critical to optimize counseling for families. Multi-institutional studies are warranted to identify whether these findings are generalizable.

Suicide and Self-Harm in Adolescents During the COVID-19 Pandemic: A U.S. Virtual Pediatric Systems, LLC, Database Study of PICU Admissions, 2016-2021.

OBJECTIVES: To characterize the epidemiology of suicide and self-harm among adolescents admitted to PICUs during the first 2 years of the COVID-19 pandemic in the United States. DESIGN: Descriptive analysis of a large, multicenter, quality-controlled database (Virtual Pediatric Systems [VPS]), and of a national public health dataset (U.S. Centers for Disease Control and Prevention web-based Wide-ranging ONline Data for Epidemiology Research [CDC WONDER]). SETTING: The 69 PICUs participating in the VPS database that contributed data for the entire the study period, January 1, 2016, to December 31, 2021. PATIENTS: Adolescents older than 12 years to younger than 18 years old admitted to a participating PICU during the study period with a diagnosis involving self-harm or a suicide attempt (VPS sample), or adolescent suicide deaths over the same period (CDC WONDER sample). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We identified 10,239 suicide deaths and 7,692 PICU admissions for self-harm, including 5,414 admissions in the pre-pandemic period (Q1-2016 to Q1-2020) and 2,278 in the pandemic period (Q2-2020 to Q4-2021). Compared with the pre-pandemic period, there was no increase in the median (interquartile range) number of suicide deaths per quarter (429 [399-453] vs. 416 [390-482]) or PICU admissions for self-harm per quarter (315 [289-353] vs. 310 [286-387]) during the pandemic period, respectively. There was an increase in the ratio of self-harm PICU admissions to all-cause PICU admissions per quarter during the pandemic (1.98 [1.43-2.12]) compared with the pre-pandemic period per quarter (1.59 [1.46-1.74]). We also observed a significant decrease in all-cause PICU admissions per quarter early in the pandemic compared with the pre-pandemic period (16,026 [13,721-16,297] vs. 19,607 [18,371-20,581]). CONCLUSIONS: The number of suicide deaths and PICU admissions per quarter for self-harm remained relatively constant during the pandemic, while the number of all-cause PICU admissions per quarter decreased compared with the pre-pandemic period. The resultant higher ratio of self-harm admissions to all-cause PICU admissions may have contributed to the perception that more adolescents required critical care for mental health-related conditions early in the pandemic.

Virtual Collaborative Behavioral Health Model in a Community Pediatric Network: Two-Year Outcomes.

Due to the pervasive shortage of behavioral health (BH) specialists, collaborative partnerships between pediatric primary care practitioners (PPCPs) and BH specialists can enhance provision of BH services by PPCPs. We aimed to create a new model of collaborative care that was mostly virtual, affordable, and scalable. The pilot program was implemented in 18 practices (48 PPCPs serving approximately 150 000 patients) in 2 consecutive cohorts. Outcomes were assessed by administering pre-program and post-program surveys. Across the 18 practices, PPCPs reported significantly increased confidence in their BH knowledge and skills, and significantly increased their provision of target BH services. Barriers to BH service provision (resources, time, and staff) were unchanged. This compact, mostly virtual model of BH collaboration appears to be beneficial to PPCPs while also offering convenience to patients and affordability and scalability to the practice network.

From Hospital to Home: Referrals to Pediatric Hospice and Home-based Palliative Care.

CONTEXT: Hospital-based pediatric palliative care (PPC) may help optimize referrals to community-based hospice and home-based palliative care (HBPC) for children with serious illness, yet little is known about their referral practices. OBJECTIVES: To describe community-based program referrals from a PPC team, identifying factors associated with referral type, and potential misalignment between patient needs and referral received. METHODS: Chart abstraction of patients seen in 2017 by the PPC team of a large, urban children's hospital, followed for at least 6 months or until death, including clinical and demographic characteristics, and referrals to hospice and HBPC. RESULTS: Of the 302 study-eligible patients, 25% died during the hospitalization of the first 2017 visit.  Of the remaining 228 patients, 42 (18.4%) were referred to HBPC and 58 (25.4%) to hospice. Excluding patients referred to hospice care, only one-third with demographic eligibility were referred to HBPC; those seen in the ICU were least likely to be referred.  Over half of the 58 patients referred to hospice died within the study period (n = 34, 58.6%); descendants were more likely to have cancer (P = 0.002) and less likely to have a neurologic (P = 0.021) diagnosis. CONCLUSION: Despite demographic eligibility, a minority of patients seen by a hospital-based PPC team received referrals for hospice or HBPC.  Children discharged from an ICU and those with neurologic conditions may be at higher risk of missing referrals best aligned with their needs.  Future research should identify and address causes of referral misalignment. Advocacy for programs adaptable to patients' changing needs may also be needed.

Characteristics and Outcomes of Critically Ill Children With Multisystem Inflammatory Syndrome.

OBJECTIVES: To characterize the prevalence of pediatric critical illness from multisystem inflammatory syndrome in children (MIS-C) and to assess the influence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strain on outcomes. DESIGN: Retrospective cohort study. SETTING: Database evaluation using the Virtual Pediatric Systems Database. PATIENTS: All children with MIS-C admitted to the PICU in 115 contributing hospitals between January 1, 2020, and June 30, 2021. MEASUREMENTS AND MAIN RESULTS: Of the 145,580 children admitted to the PICU during the study period, 1,338 children (0.9%) were admitted with MIS-C with the largest numbers of children admitted in quarter 1 (Q1) of 2021 ( n = 626). The original SARS-CoV-2 viral strain and the D614G Strain were the predominant strains through 2020, with Alpha B.1.1.7 predominating in Q1 and quarter 2 (Q2) of 2021. Overall, the median PICU length of stay (LOS) was 2.7 days (25-75% interquartile range [IQR], 1.6-4.7 d) with a median hospital LOS of 6.6 days (25-75% IQR, 4.7-9.3 d); 15.2% received mechanical ventilation with a median duration of mechanical ventilation of 3.1 days (25-75% IQR, 1.9-5.8 d), and there were 11 hospital deaths. During the study period, there was a significant decrease in the median PICU and hospital LOS and a decrease in the frequency of mechanical ventilation, with the most significant decrease occurring between quarter 3 and quarter 4 (Q4) of 2020. Children admitted to a PICU from the general care floor or from another ICU/step-down unit had longer PICU LOS than those admitted directly from an emergency department. CONCLUSIONS: Overall mortality from MIS-C was low, but the disease burden was high. There was a peak in MIS-C cases during Q1 of 2021, following a shift in viral strains in Q1 of 2021. However, an improvement in MIS-C outcomes starting in Q4 of 2020 suggests that viral strain was not the driving factor for outcomes in this population.

The effect of anesthesia without opioid on perioperative opioid demand in children with severe obstructive sleep apnea (OSA) for adenotonsillectomies - single-center retrospective observational study.

BACKGROUND: Children with severe obstructive sleep apnea (OSA) carry a higher risk of respiratory complications after adenotonsillectomy. Their altered sensitivity to opioids may be a significant contributor to respiratory morbidity. The purpose of this study was to identify how anesthesia without opioids affects perioperative opioid demand and postoperative course. METHODS: A chart review of children with severe OSA (apnea hypoxia index; AHI ≥ 10) undergoing adenotonsillectomies was performed. Comorbidities and perioperative medications were documented. Perioperative opioid doses within 48 h of procedure were calculated as morphine equivalents (mcg/kg). Pain scores, rescue medications, and postoperative complications in PICU and non-PICU settings were also documented. Anesthesia without opioid and with opioid groups were compared. RESULTS: The analysis included 225 children. A significantly higher percentage of children received no postoperative opioids in the anesthesia without opioid group compared to those with opioid (46 of 88 children vs. 43 of 137; P < 0.05). The incidence of severe postoperative pain between the two groups was not different in PICU (P = 0.88) or non-PICU setting (P = 0.84). Perioperative opioid administration was significantly lower in anesthesia without opioid (median, Q1, Q3: 0.0, 0.0, 83.0) compared to with opioid (144.4, 72.5, 222.2; P < 0.01). Anesthesia without opioid was one of the independent factors to achieve perioperative opioid avoidance (<50mcg/kg). CONCLUSIONS: Anesthesia without opioid for children with severe OSA for tonsillectomy significantly reduced perioperative demand for opioid and did not affect the occurrence of severe pain. Anesthesia without opioid is an effective strategy to minimalize opioid demand perioperatively for children with severe OSA for tonsillectomy.

PICU admission and complications following adenotonsillectomies in pediatric patients: A retrospective cohort study.

BACKGROUND: Children with obstructive sleep apnea (OSA) have higher risks of post-operative respiratory complication after adenotonsillectomy. However, there is no clinical standard criteria for pediatric intensive care unit (PICU) admission following adenotonsillectomy. The purpose of this study was to identify perioperative risk factors associated with the need for PICU level care after adenotonsillectomy. METHODS: We performed a retrospective chart review of children with severe OSA (apnea hypopnea index on polysomnography; AHI ≥10) and/or post-operative PICU admission at a tertiary academic center from May 2010 to September 2018. We collected demographics, pre-existing comorbidities, perioperative medications, and post-operative complications. We defined a primary outcome as escalation of airway management while in the PICU or PICU stay >48 h. Airway escalation included the need for an invasive airway, new CPAP application, increased CPAP setting, or increased supplemental oxygen. RESULTS: Analysis included 278 children with severe OSA and/or PICU admission. Median age was 6.6 years old; 181 (65%) were admitted to the PICU, and 60 (21.5%) had the composite outcome of escalation of airway management or prolonged stay. In patients with an escalation of airway management, 28 needed intubation or mechanical ventilation. Multivariable logistic regression showed intraoperative respiratory complications, polysomnography (PSG) peak end-tidal CO2 (EtCO2) reading >60 mmHg, and the presence of neuromuscular disease as significant associated factors for escalation of airway management or prolonged PICU stay (P values < 0.01; odd ratios 3.4, 5.3, and 5.4, respectively). CONCLUSION: For children following adenotonsillectomy, PSG EtCO2 ≥ 60%, preexisting neuromuscular disease, and intraoperative complications (hypoxia, difficult airway, etc.) were independently associated with escalation of airway management or prolonged stay. AHI was not an independent predictor for PICU complication. We concluded factors should be considered for PICU admission in addition to AHI.

School Closures in the United States and Severe Respiratory Illnesses in Children: A Normalized Nationwide Sample.

OBJECTIVES: To determine the association between nationwide school closures and prevalence of common admission diagnoses in the pediatric critical care unit. DESIGN: Retrospective cohort study. SETTING: National database evaluation using the Virtual Pediatric Systems LLC database. PATIENTS: All patients admitted to the PICU in 81 contributing hospitals in the United States. MEASUREMENTS AND MAIN RESULTS: Diagnosis categories were determined for all 110,418 patients admitted during the 20-week study period in each year (2018, 2019, and 2020). Admission data were normalized relative to statewide school closure dates for each patient using geographic data. The "before school closure" epoch was defined as 8 weeks prior to school closure, and the "after school closure" epoch was defined as 12 weeks following school closure. For each diagnosis, admission ratios for each study day were calculated by dividing 2020 admissions by 2018-2019 admissions. The 10 most common diagnosis categories were examined. Significant changes in admission ratios were identified for bronchiolitis, pneumonia, and asthma. These changes occurred at 2, 8, and 35 days following school closure, respectively. PICU admissions decreased by 82% for bronchiolitis, 76% for pneumonia, and 76% for asthma. Nonrespiratory diseases such as diabetic ketoacidosis, status epilepticus, traumatic injury, and poisoning/ingestion did not show significant changes following school closure. CONCLUSIONS: School closures are associated with a dramatic reduction in the prevalence of severe respiratory disease requiring PICU admission. School closure may be an effective tool to mitigate future pandemics but should be balanced with potential academic, economic, mental health, and social consequences.

The Temporal Relationship Between Local School Closure and Increased Incidence of Pediatric Diabetic Ketoacidosis.

Importance: The incidence of pediatric diabetic ketoacidosis (DKA) increased early in the COVID-19 pandemic, but the relative contribution of behavioral changes and viral-related pathophysiology are unknown. Objective: To evaluate the relationship between school closure date and onset of increased DKA to help clarify the etiology of the increased incidence. Design: A multi-center, quality-controlled Pediatric Intensive Care Unit (PICU) database was used to identify the number of admissions to a participating PICU with DKA on each calendar day from 60 days before local school closure to 90 days after, and compared to baseline data from the same periods in 2018-2019. Interrupted time series and multiple linear regression analyses were used to identify admission rates that differed significantly between 2020 and baseline. Setting: Eighty-one PICUs in the United StatesParticipants: Children ages 29 days to 17 years admitted to a PICU with DKAExposures: Statewide school closureMain outcome/measure: Rate of admission to the PICU for DKA. Results: There were 1936 admissions for children with DKA in 2020 and 1795 admissions/year to those same PICUs in 2018-2019. Demographics and clinical outcomes did not differ before school closure, but pandemic-era patients were less often white and had longer hospital length of stay in the post-school closure period. The difference between 2020 admissions and 2018-2019 admissions was not different than zero before school closure, and significantly higher than zero after school closure, but was significantly increased in 2020 at >30 days after school closure (p = 0.039). Conclusions/Relevance: An increase in pediatric DKA admissions began one month after school closures. Given that behavioral changes started near school closure dates and viral activity peaked weeks after, this suggests that behavioral factors may not be the primary etiology and it is possible that SARS-CoV-2 infection may have direct effects on pediatric DKA.

Mechanical power in pediatric acute respiratory distress syndrome: a PARDIE study.

BACKGROUND: Mechanical power is a composite variable for energy transmitted to the respiratory system over time that may better capture risk for ventilator-induced lung injury than individual ventilator management components. We sought to evaluate if mechanical ventilation management with a high mechanical power is associated with fewer ventilator-free days (VFD) in children with pediatric acute respiratory distress syndrome (PARDS). METHODS: Retrospective analysis of a prospective observational international cohort study. RESULTS: There were 306 children from 55 pediatric intensive care units included. High mechanical power was associated with younger age, higher oxygenation index, a comorbid condition of bronchopulmonary dysplasia, higher tidal volume, higher delta pressure (peak inspiratory pressure-positive end-expiratory pressure), and higher respiratory rate. Higher mechanical power was associated with fewer 28-day VFD after controlling for confounding variables (per 0.1 J·min-1·Kg-1 Subdistribution Hazard Ratio (SHR) 0.93 (0.87, 0.98), p = 0.013). Higher mechanical power was not associated with higher intensive care unit mortality in multivariable analysis in the entire cohort (per 0.1 J·min-1·Kg-1 OR 1.12 [0.94, 1.32], p = 0.20). But was associated with higher mortality when excluding children who died due to neurologic reasons (per 0.1 J·min-1·Kg-1 OR 1.22 [1.01, 1.46], p = 0.036). In subgroup analyses by age, the association between higher mechanical power and fewer 28-day VFD remained only in children < 2-years-old (per 0.1 J·min-1·Kg-1 SHR 0.89 (0.82, 0.96), p = 0.005). Younger children were managed with lower tidal volume, higher delta pressure, higher respiratory rate, lower positive end-expiratory pressure, and higher PCO2 than older children. No individual ventilator management component mediated the effect of mechanical power on 28-day VFD. CONCLUSIONS: Higher mechanical power is associated with fewer 28-day VFDs in children with PARDS. This association is strongest in children < 2-years-old in whom there are notable differences in mechanical ventilation management. While further validation is needed, these data highlight that ventilator management is associated with outcome in children with PARDS, and there may be subgroups of children with higher potential benefit from strategies to improve lung-protective ventilation. TAKE HOME MESSAGE: Higher mechanical power is associated with fewer 28-day ventilator-free days in children with pediatric acute respiratory distress syndrome. This association is strongest in children <2-years-old in whom there are notable differences in mechanical ventilation management.

Epidemiology and Outcomes of Critically Ill Children at Risk for Pediatric Acute Respiratory Distress Syndrome: A Pediatric Acute Respiratory Distress Syndrome Incidence and Epidemiology Study.

OBJECTIVES: Interventional trials aimed at pediatric acute respiratory distress syndrome prevention require accurate identification of high-risk patients. In this study, we aimed to characterize the frequency and outcomes of children meeting "at risk for pediatric acute respiratory distress syndrome" criteria as defined by the Pediatric Acute Lung Injury Consensus Conference. DESIGN: Planned substudy of the prospective multicenter, international Pediatric Acute Respiratory Distress Syndrome Incidence and Epidemiology study conducted during 10 nonconsecutive weeks (May 2016-June 2017). SETTING: Thirty-seven international PICUs. PATIENTS: Three-hundred ten critically ill children meeting Pediatric Acute Lung Injury Consensus Conference "at-risk for pediatric acute respiratory distress syndrome" criteria. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We evaluated the frequency of children at risk for pediatric acute respiratory distress syndrome and rate of subsequent pediatric acute respiratory distress syndrome diagnosis and used multivariable logistic regression to identify factors associated with subsequent pediatric acute respiratory distress syndrome. Frequency of at risk for pediatric acute respiratory distress syndrome was 3.8% (95% CI, 3.4-5.2%) among the 8,122 critically ill children who were screened and 5.8% (95% CI, 5.2-6.4%) among the 5,334 screened children on positive pressure ventilation or high-flow oxygen. Among the 310 at-risk children, median age was 2.1 years (interquartile range, 0.5-7.3 yr). Sixty-six children (21.3%) were subsequently diagnosed with pediatric acute respiratory distress syndrome, a median of 22.6 hours (interquartile range, 9.8-41.0 hr) later. Subsequent pediatric acute respiratory distress syndrome was associated with increased mortality (21.2% vs 3.3%; p < 0.001) and longer durations of invasive ventilation and PICU care. Subsequent pediatric acute respiratory distress syndrome rate did not differ by respiratory support modality at the time of meeting at risk criteria but was independently associated with lower initial saturation:Fio2 ratio, progressive tachycardia, and early diuretic administration. CONCLUSIONS: The Pediatric Acute Lung Injury Consensus Conference "at-risk for pediatric acute respiratory distress syndrome" criteria identify critically ill children at high risk of pediatric acute respiratory distress syndrome and poor outcomes. Interventional trials aimed at pediatric acute respiratory distress syndrome prevention should target patients early in their illness course and include patients on high-flow oxygen and positive pressure ventilation.

Suicide and Self-Harm in Children and Adolescents Admitted to PICUs in the United States.

OBJECTIVES: To characterize the epidemiology of children and adolescents admitted for deliberate self-harm to PICUs in the United States by examining patient demographics, diagnoses, modes of self-harm, and outcomes. DESIGN: Descriptive analysis of a large, multicenter, quality-controlled database. SETTING: The 137 PICUs participating in the Virtual Pediatric Systems database during the study period. PATIENTS: Children between 6 and 18 years old admitted to a participating PICU from January 1, 2009, to December 31, 2017, with a diagnosis involving deliberate self-harm or a suicide attempt. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 9,197 admissions for self-harm, females accounted for 6,740 (73.3%), whereas males incurred 174 of the 284 deaths (61.3%). Admissions for self-harm doubled over the study period (0.56% in 2009 vs 1.13% in 2017), with an increase observed across every age group. After PICU care, most patients were transferred to a general care floor (51.1%) or to a psychiatric rehabilitation facility (31.8%). Intentional drug ingestion (84%) was the most common mode of self-harm but was associated with less than 1% of the fatalities. Asphyxia/hanging or firearms were a factor in 411 (4.5%) and 106 (1.2%) of the admissions but were associated with 117 (28.5%) and 55 (51.9%) of the deaths, respectively. CONCLUSIONS: PICU admissions due to self-harm increased for all age groups during the study period. Females accounted for most of these admissions, whereas males accrued most of the in-hospital deaths. Intentional drug ingestion was the most common mode of self-harm and was rarely fatal, whereas asphyxia and firearms were the mechanisms associated with the highest mortality.

Effect of an Immersive Virtual Reality Intervention on Pain and Anxiety Associated With Peripheral Intravenous Catheter Placement in the Pediatric Setting: A Randomized Clinical Trial.

Importance: The inclusion of digital therapeutics (eg, virtual reality [VR] systems) for the management of pain and anxiety associated with routine acutely painful medical procedures may have a substantial impact on treatment adherence and improve long-term health outcomes among young patients. Objective: To determine whether a VR intervention decreases pain and anxiety among patients undergoing peripheral intravenous catheter (PIVC) placement compared with standard care in the pediatric setting. Design, Setting, and Participants: This randomized clinical trial was conducted from April 12, 2017, to July 24, 2019, among 107 patients aged 10 to 21 years who were undergoing PIVC placement in 2 clinical settings (a radiology department and an infusion center) at an urban pediatric academic medical center in the US. Patients, caregivers, and clinicians completed pre-PIVC and post-PIVC placement questionnaires measuring patient pain, anxiety, and anxiety sensitivity; only participants with complete data from before and after PIVC placment were included in the analyses. Interventions: Patients were randomized to receive standard care (simple distraction techniques [eg, music, coloring, singing, and talking] and the application of numbing cream) or a VR intervention using a balanced computer-generated randomization scheme stratified by sex. All patients who received the VR intervention were offered concurrent standard care; however, VR plus standard care was not specifically examined. Main Outcomes and Measures: Primary outcomes were patient pain (measured by the Faces Pain Scale-Revised) and anxiety (measured by a visual analogue scale) reported by the patient, caregiver, and clinician after PIVC placement. Outcomes were analyzed using generalized linear modeling with backward stepwise selection for final model building. Results: A total of 107 patients (median age, 14.7 years [interquartile range, 12.8-16.9 years]; 63 male participants [58.9%]) completed the clinical trial; 54 patients received standard care, and 53 patients also received the VR intervention. Patients who received the VR intervention compared with standard care had significantly lower mean post-PIVC anxiety scores when patient-reported (1.85 points [95% CI, 1.28-2.41 points] vs 3.14 points [95% CI, 2.59-3.68 points]; P < .001) and clinician-reported (2.04 points [95% CI, 1.37-2.71 points] vs 3.34 points [95% CI, 2.69-3.99 points]; P = .002). Patients in the VR group vs the standard care group also had significantly lower mean post-PIVC pain scores when patient-reported (1.34 points [95% CI, 0.63-2.05 points] vs 2.54 points [95% CI, 1.78-3.30 points]; P = .002), caregiver-reported (1.87 points [95% CI, 0.99-2.76 points] vs 3.01 points [95% CI. 1.98-4.03 points]; P = .04), and clinician-reported (2.05 points [95% CI, 1.47-2.63 points] vs 3.59 points [95% CI, 2.97-4.22 points]; P < .001). Aside from lower levels of baseline pain and anxiety, no demographic variables among patients in the VR group were associated with lower levels of post-PIVC pain and anxiety. Conclusions and Relevance: In this randomized clinical trial, patients undergoing PIVC placement who received a VR intervention experienced significantly less anxiety and pain compared with those who received standard care. The use of patient, caregiver, and clinician data provided a variety of subjective information, as well as observable and objective data regarding perceived pain and anxiety beyond patient reporting alone.

Adherence to Lung-Protective Ventilation Principles in Pediatric Acute Respiratory Distress Syndrome: A Pediatric Acute Respiratory Distress Syndrome Incidence and Epidemiology Study.

OBJECTIVES: To describe mechanical ventilation management and factors associated with nonadherence to lung-protective ventilation principles in pediatric acute respiratory distress syndrome. DESIGN: A planned ancillary study to a prospective international observational study. Mechanical ventilation management (every 6 hr measurements) during pediatric acute respiratory distress syndrome days 0-3 was described and compared with Pediatric Acute Lung Injury Consensus Conference tidal volume recommendations (< 7 mL/kg in children with impaired respiratory system compliance, < 9 mL/kg in all other children) and the Acute Respiratory Distress Syndrome Network lower positive end-expiratory pressure/higher Fio2 grid recommendations. SETTING: Seventy-one international PICUs. PATIENTS: Children with pediatric acute respiratory distress syndrome. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Analyses included 422 children. On pediatric acute respiratory distress syndrome day 0, median tidal volume was 7.6 mL/kg (interquartile range, 6.3-8.9 mL/kg) and did not differ by pediatric acute respiratory distress syndrome severity. Plateau pressure was not recorded in 97% of measurements. Using delta pressure (peak inspiratory pressure - positive end-expiratory pressure), median tidal volume increased over quartiles of median delta pressure (p = 0.007). Median delta pressure was greater than or equal to 18 cm H2O for all pediatric acute respiratory distress syndrome severity levels. In severe pediatric acute respiratory distress syndrome, tidal volume was greater than or equal to 7 mL/kg 62% of the time, and positive end-expiratory pressure was lower than recommended by the positive end-expiratory pressure/Fio2 grid 70% of the time. In multivariable analysis, tidal volume nonadherence was more common with severe pediatric acute respiratory distress syndrome, fewer PICU admissions/yr, non-European PICUs, higher delta pressure, corticosteroid use, and pressure control mode. Adherence was associated with underweight stature and cuffed endotracheal tubes. In multivariable analysis, positive end-expiratory pressure/Fio2 grid nonadherence was more common with higher pediatric acute respiratory distress syndrome severity, ventilator decisions made primarily by the attending physician, pre-ICU cardiopulmonary resuscitation, underweight stature, and age less than 2 years. Adherence was associated with respiratory therapist involvement in ventilator management and longer time from pediatric acute respiratory distress syndrome diagnosis. Higher nonadherence to tidal volume and positive end-expiratory pressure recommendations were independently associated with higher mortality and longer duration of ventilation after adjustment for confounding variables. In stratified analyses, these associations were primarily influenced by children with severe pediatric acute respiratory distress syndrome. CONCLUSIONS: Nonadherence to lung-protective ventilation principles is common in pediatric acute respiratory distress syndrome and may impact outcome. Modifiable factors exist that may improve adherence.

Changes in Pediatric ICU Utilization and Clinical Trends During the Coronavirus Pandemic.

BACKGROUND: Children have been less affected by the COVID-19 pandemic, but its repercussions on pediatric illnesses may have been significant. This study examines the indirect impact of the pandemic on a population of critically ill children in the United States. RESEARCH QUESTION: Were there significantly fewer critically ill children admitted to PICUs during the second quarter of 2020, and were there significant changes in the types of diseases admitted? STUDY DESIGN AND METHODS: This retrospective observational cohort study used the Virtual Pediatric Systems database. Participants were 160,295 children admitted to the PICU at 77 sites in the United States during quarters 1 (Q1) and 2 (Q2) of 2017 to 2019 (pre-COVID-19) and 2020 (COVID-19). RESULTS: The average number of admissions was similar between pre-COVID-19 Q1 and COVID-19 Q1 but decreased by 32% from pre-COVID-19 Q2 to COVID-19 Q2 (20,157 to 13,627 admissions per quarter). The largest decreases were in respiratory conditions, including asthma (1,327 subjects in pre-COVID-19 Q2 (6.6% of patients) vs 241 subjects in COVID-19 Q2 (1.8%; P < .001) and bronchiolitis (1,299 [6.5%] vs 121 [0.9%]; P < .001). The percentage of trauma admissions increased, although the raw number of trauma admissions decreased. Admissions for diabetes mellitus and poisoning/ingestion also increased. In the multivariable model, illness severity-adjusted odds of ICU mortality for PICU patients during COVID-19 Q2 increased compared with pre-COVID-19 Q2 (OR, 1.165; 95% CI, 1.00-1.357; P = .049). INTERPRETATION: Pediatric critical illness admissions decreased substantially during the second quarter of 2020, with significant changes in the types of diseases seen in PICUs in the United States. There was an increase in mortality in children admitted to the PICU during this period.

Intravitreal sirolimus for persistent, exudative age-related macular degeneration: a Pilot Study.

BACKGROUND AND OBJECTIVE: To evaluate the safety and efficacy of intravitreal sirolimus for persistent, exudative age-related macular degeneration (AMD). METHODS: This institutional review board approved, registered (NCT02357342), prospective, subject-masked, single center, randomized controlled trial in subjects with persistent, exudative Age-related macular degeneration compared intravitreal sirolimus monotherapy (every 2 months) versus monthly anti-vascular endothelial growth factor (VEGF) over six months. RESULTS: 20 subjects were randomized to each arm of the trial. Upon completion of the trial 20 patients were analyzed in the control (anti-vascular endothelial growth factor) group and 17 patients were analyzed in the treatment (sirolimus) group. On average, subjects had 33 previous anti-VEGF injections prior to entry. The primary end-point, mean central subfield thickness (CST), increased by 20 µm in the anti-vascular endothelial growth factor group and decreased by 40 µm in the sirolimus group (p = 0.03). Visual acuity outcomes were similar between groups. Serious ocular adverse events in the sirolimus group included one subject each with anterior uveitis, central retinal artery occlusion and subretinal hemorrhage. CONCLUSION: Monotherapy with intravitreal sirolimus for subjects with persistent, exudative age-related macular degeneration appears to have a limited positive anatomic benefit. The presence of adverse events in the experimental group merits further evaluation, potentially as an adjuvant therapy. Trial registration This trial was registered with the clinicaltrials.gov, NCT02357342, and was approved by the institutional review board at Advarra. Funding was provided by an investigator-initiated grant from Santen. Santen played no role in the design or implementation of this study.

The Association Between Ventilatory Ratio and Mortality in Children and Young Adults.

BACKGROUND: The ventilatory ratio (VR) is a dead-space marker associated with mortality in mechanically ventilated adults with ARDS. The end-tidal alveolar dead space fraction (AVDSf) has been associated with mortality in children. However, AVDSf requires capnography measurements, whereas VR does not. We sought to examine the prognostic value of VR, in comparison to AVDSf, in children and young adults with acute hypoxemic respiratory failure. METHODS: We conducted a retrospective study of prospectively collected data from 180 mechanically ventilated children and young adults with acute hypoxemic respiratory failure. VR was calculated as (minute ventilation × [Formula: see text])/(age-adjusted predicted minute ventilation × 37.5). AVDSf was calculated as [Formula: see text]. RESULTS: VR and AVDSf had a moderate correlation (rho 0.31, P < .001). VR was similar between survivors at 1.22 (interquartile range [IQR] 1.0-1.52) and nonsurvivors at 1.30 (IQR 0.96-1.95) (P = .2). AVDSf was lower in survivors at 0.12 (IQR 0.03-0.23) than nonsurvivors at 0.24 (IQR 0.13-0.33) (P < .001). In logistic regression and competing risk regression analyses, VR was not associated with mortality or rate of extubation at any given time (competing risk death; all P > .3). An AVDSf in the highest 2 quartiles, in comparison to the lowest quartile (AVDSf < 0.06), was associated with higher mortality after adjustment for oxygenation index and severity of illness (AVDSf ≥ 0.15-0.26: odds ratio 3.58, 95% CI 1.02-12.64, P = .047, and AVDSf ≥ 0.26: odds ratio 3.91 95% CI-1.03-14.83, P = .045). At any given time after intubation, a child with an AVDSf ≥ 0.26 was less likely to be extubated than a child with an AVDSf < 0.06, after adjustment for oxygenation index and severity of illness (AVDSf ≥ 0.26: subdistribution hazard ratio 0.55, 95% CI 0.33-0.94, P = .03). CONCLUSIONS: VR should not be used for prognostic purposes in children and young adults. AVDSf added prognostic information to the severity of oxygenation defect and overall severity of illness in children and young adults, consistent with previous research.
