Item Aligning use of intensive care with patient values in the USA: past, present, and future.(Elsevier, 2019-07-01) Turnbull, Alison E; Bosslet, Gabriel T.; Kross, Erin K.; Medicine, School of MedicineFor more than three decades, both medical professionals and the public have worried that many patients receive non-beneficial care in US intensive care units during their final months of life. Some of these patients wish to avoid severe cognitive and physical impairments, and protracted deaths in the hospital setting. Recognising when intensive care will not restore a person’s health, and helping patients and families embrace goals related to symptom relief, interpersonal connection, or spiritual fulfilment are central challenges of critical care practice in the USA. We review trials from the past decade of interventions designed to address these challenges, and present reasons why evaluating, comparing, and implementing these interventions have been difficult. Careful scrutiny of the design and interpretation of past trials can show why improving goal concordant care has been so elusive, and suggest new directions for the next generation of research.Item Continuity Strategies for Long-Stay PICU Patients: Consensus Statements From the Lucile Packard Foundation PICU Continuity Panel(Wolters Kluwer, 2023) Edwards, Jeffrey D.; Wocial, Lucia D.; Madrigal, Vanessa N.; Moon, Michelle M.; Ramey-Hunt, Cheryl; Walter, Jennifer K.; Baird, Jennifer D.; Leland, Brian D.; Pediatrics, School of MedicineObjectives: To develop consensus statements on continuity strategies using primary intensivists, primary nurses, and recurring multidisciplinary team meetings for long-stay patients (LSPs) in PICUs. Participants: The multidisciplinary Lucile Packard Foundation PICU Continuity Panel comprising parents of children who had prolonged PICU stays and experts in several specialties/professions that care for children with medical complexity in and out of PICUs. Design/methods: We used modified RAND Delphi methodology, with a comprehensive literature review, Delphi surveys, and a conference, to reach consensus. The literature review resulted in a synthesized bibliography, which was provided to panelists. We used an iterative process to generate draft statements following panelists' completion of four online surveys with open-ended questions on implementing and sustaining continuity strategies. Panelists were anonymous when they voted on revised draft statements. Agreement of 80% constituted consensus. At a 3-day virtual conference, we discussed, revised, and re-voted on statements not reaching or barely reaching consensus. We used Grading of Recommendations Assessment, Development, and Evaluation to assess the quality of the evidence and rate the statements' strength. The Panel also generated outcome, process, and balancing metrics to evaluate continuity strategies. Results: The Panel endorsed 17 consensus statements in five focus areas of continuity strategies (Eligibility Criteria, Initiation, Standard Responsibilities, Resources Needed to Implement, Resources Needed to Sustain). The quality of evidence of the statements was low to very low, highlighting the limited evidence and the importance of panelists' experiences/expertise. The strength of the statements was conditional. An extensive list of potential evaluation metrics was generated. Conclusions: These expert/parent-developed consensus statements provide PICUs with novel summaries on how to operationalize, implement, and sustain continuity strategies for LSP, a rapidly growing, vulnerable, resource-intensive population in PICUs.Item Effectiveness of BNT162b2 Vaccine against Critical Covid-19 in Adolescents(Massachusetts Medical Society, 2022) Olson, Samantha M.; Newhams, Margaret M.; Halasa, Natasha B.; Price, Ashley M.; Boom, Julie A.; Sahni, Leila C.; Pannaraj, Pia S.; Irby, Katherine; Walker, Tracie C.; Schwartz, Stephanie P.; Maddux, Aline B.; Mack, Elizabeth H.; Bradford, Tamara T.; Schuster, Jennifer E.; Nofziger, Ryan A.; Cameron, Melissa A.; Chiotos, Kathleen; Cullimore, Melissa L.; Gertz, Shira J.; Levy, Emily R.; Kong, Michele; Cvijanovich, Natalie Z.; Staat, Mary A.; Kamidani, Satoshi; Chatani, Brandon M.; Bhumbra, Samina S.; Bline, Katherine E.; Gaspers, Mary G.; Hobbs, Charlotte V.; Heidemann, Sabrina M.; Maamari, Mia; Flori, Heidi R.; Hume, Janet R.; Zinter, Matt S.; Michelson, Kelly N.; Zambrano, Laura D.; Campbell, Angela P.; Patel, Manish M.; Randolph, Adrienne G.; Pediatrics, School of MedicineBackground: The increasing incidence of pediatric hospitalizations associated with coronavirus disease 2019 (Covid-19) caused by the B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the United States has offered an opportunity to assess the real-world effectiveness of the BNT162b2 messenger RNA vaccine in adolescents between 12 and 18 years of age. Methods: We used a case-control, test-negative design to assess vaccine effectiveness against Covid-19 resulting in hospitalization, admission to an intensive care unit (ICU), the use of life-supporting interventions (mechanical ventilation, vasopressors, and extracorporeal membrane oxygenation), or death. Between July 1 and October 25, 2021, we screened admission logs for eligible case patients with laboratory-confirmed Covid-19 at 31 hospitals in 23 states. We estimated vaccine effectiveness by comparing the odds of antecedent full vaccination (two doses of BNT162b2) in case patients as compared with two hospital-based control groups: patients who had Covid-19-like symptoms but negative results on testing for SARS-CoV-2 (test-negative) and patients who did not have Covid-19-like symptoms (syndrome-negative). Results: A total of 445 case patients and 777 controls were enrolled. Overall, 17 case patients (4%) and 282 controls (36%) had been fully vaccinated. Of the case patients, 180 (40%) were admitted to the ICU, and 127 (29%) required life support; only 2 patients in the ICU had been fully vaccinated. The overall effectiveness of the BNT162b2 vaccine against hospitalization for Covid-19 was 94% (95% confidence interval [CI], 90 to 96); the effectiveness was 95% (95% CI, 91 to 97) among test-negative controls and 94% (95% CI, 89 to 96) among syndrome-negative controls. The effectiveness was 98% against ICU admission and 98% against Covid-19 resulting in the receipt of life support. All 7 deaths occurred in patients who were unvaccinated. Conclusions: Among hospitalized adolescent patients, two doses of the BNT162b2 vaccine were highly effective against Covid-19-related hospitalization and ICU admission or the receipt of life support.

The purpose of this study was to examine the exposure trends and patient outcomes in 2018-2019 compared with 2020-2021 amidst the COVID-19 pandemic. Methods: This was a retrospective cohort study of patients 18 years of age or younger with a suspected toxicologic exposure from January 2018 to March 2021. The primary endpoint was rate of PICU admissions between the 2 cohorts. Secondary endpoints included medical outcome stratified by severity, PICU length of stay, and need for mechanical ventilation. Results: Our study included a total of 340 patients with median age 14.5 (IQR, 11.9-16.1) years. There was no significant difference in age, sex, or race between the 2 cohorts. The percentage of patients admitted to the PICU for poison exposures was significantly higher in the COVID-19 cohort compared with the pre-COVID-19 cohort (8.4% vs 3.7%, p < 0.01). Severity of medical outcomes differed between the groups; the COVID-19 cohort had more extreme clinical presentations of no effect or death (p < 0.01). No significant difference was found among the remaining secondary outcomes. Classes of substances ingested were comparable with baseline poison center data. Conclusions: Poisoning-related PICU admissions occurred at more than twice the pre-pandemic rate. This may emphasize the effect of the COVID-19 pandemic on pediatric access and exposure to poisons.Item The Impact of Increased Awareness of Acute Kidney Injury in the Neonatal Intensive Care Unit on Acute Kidney Injury Incidence and Reporting: Results of a Retrospective Cohort Study(Springer Nature, 2020-09) Starr, Michelle C.; Kula, Alexander; Lieberman, Joshua; Menon, Shina; Perkins, Anthony J.; Lam, Teresa; Chabra, Shilpi; Hingorani, Sangeeta; Pediatrics, School of MedicineObjective: To evaluate the impact of nephrology integration in the NICU on acute kidney injury (AKI) incidence, provider reporting, and nephrology referral. Study design: Cohort study in a single-center NICU from January 2012 to December 2017 (n = 1464). We assessed the impact of clinical practice changes including neonatal-nephrology rounds on the incidence of AKI. Results: AKI occurred in 318 neonates (22%). AKI occurred less frequently in those admitted after clinical practice changes (P < 0.001). After multivariable adjustment, clinical practice changes were associated with reduced odds of AKI (adjusted odds ratio, 0.31; 95% CI 0.22-0.44, P < 0.001). Provider reporting of AKI improved (P < 0.001) and more neonates were referred for nephrology follow-up (P < 0.001). Conclusions: Increased nephrology integration in the NICU was associated with decreased AKI incidence. While recognition of AKI improved, AKI remained poorly reported and nephrology AKI follow-up did not routinely occur. This study supports the importance of increased nephrology involvement in the NICU.Item Life-Threatening Complications of Influenza vs Coronavirus Disease 2019 (COVID-19) in US Children(Oxford University Press, 2023) Halasa, Natasha B.; Spieker, Andrew J.; Young, Cameron C.; Olson, Samantha M.; Newhams, Margaret M.; Amarin, Justin Z.; Moffitt, Kristin L.; Nakamura, Mari M.; Levy, Emily R.; Soma, Vijaya L.; Talj, Rana; Weiss, Scott L.; Fitzgerald, Julie C.; Mack, Elizabeth H.; Maddux, Aline B.; Schuster, Jennifer E.; Coates, Bria M.; Hall, Mark W.; Schwartz, Stephanie P.; Schwarz, Adam J.; Kong, Michele; Spinella, Philip C.; Loftis, Laura L.; McLaughlin, Gwenn E.; Hobbs, Charlotte V.; Rowan, Courtney M.; Bembea, Melania M.; Nofziger, Ryan A.; Babbitt, Christopher J.; Bowens, Cindy; Flori, Heidi R.; Gertz, Shira J.; Zinter, Matt S.; Giuliano, John S.; Hume, Janet R.; Cvijanovich, Natalie Z.; Singh, Aalok R.; Crandall, Hillary A.; Thomas, Neal J.; Cullimore, Melissa L.; Patel, Manish M.; Randolph, Adrienne G.; Pediatric Intensive Care Influenza; Overcoming COVID-19 Investigators; Pediatrics, School of MedicineBackground: Clinical differences between critical illness from influenza infection vs coronavirus disease 2019 (COVID-19) have not been well characterized in pediatric patients. Methods: We compared demographics, clinical characteristics, and outcomes of US children (aged 8 months to 17 years) admitted to the intensive care or high-acuity unit with influenza or COVID-19. Using mixed-effects models, we assessed the odds of death or requiring life support for influenza vs COVID-19 after adjustment for age, sex, race and Hispanic origin, and underlying conditions including obesity. Results: Children with influenza (n = 179) were younger than those with COVID-19 (n = 381; median, 5.2 years vs 13.8 years), less likely to be non-Hispanic Black (14.5% vs 27.6%) or Hispanic (24.0% vs 36.2%), and less likely to have ≥1 underlying condition (66.4% vs 78.5%) or be obese (21.4% vs 42.2%), and a shorter hospital stay (median, 5 days vs 7 days). They were similarly likely to require invasive mechanical ventilation (both 30.2%), vasopressor support (19.6% and 19.9%), or extracorporeal membrane oxygenation (2.2% and 2.9%). Four children with influenza (2.2%) and 11 children with COVID-19 (2.9%) died. The odds of death or requiring life support in children with influenza vs COVID-19 were similar (adjusted odds ratio, 1.30; 95% confidence interval, .78-2.15; P = .32). Conclusions: Despite differences in demographics and clinical characteristics of children with influenza or COVID-19, the frequency of life-threatening complications was similar. Our findings highlight the importance of implementing prevention measures to reduce transmission and disease severity of influenza and COVID-19.Item Machine Learning-Based Prediction Model for ICU Mortality After Continuous Renal Replacement Therapy Initiation in Children(Wolters Kluwer, 2024-12-17) Thadani, Sameer; Wu, Tzu-Chun; Wu, Danny T. Y; Kakajiwala, Aadil; Soranno, Danielle E.; Cortina, Gerard; Srivastava, Rachana; Gist, Katja M.; Menon, Shina; Pediatrics, School of MedicineBackground: Continuous renal replacement therapy (CRRT) is the favored renal replacement therapy in critically ill patients. Predicting clinical outcomes for CRRT patients is difficult due to population heterogeneity, varying clinical practices, and limited sample sizes. Objective: We aimed to predict survival to ICUs and hospital discharge in children and young adults receiving CRRT using machine learning (ML) techniques. Derivation cohort: Patients less than 25 years of age receiving CRRT for acute kidney injury and/or volume overload from 2015 to 2021 (80%). Validation cohort: Internal validation occurred in a testing group of patients from the dataset (20%). Prediction model: Retrospective international multicenter study utilizing an 80/20 training and testing cohort split, and logistic regression with L2 regularization (LR), decision tree, random forest (RF), gradient boosting machine, and support vector machine with linear kernel to predict ICU and hospital survival. Model performance was determined by the area under the receiver operating characteristic curve (AUROC) and the area under the precision-recall curve (AUPRC) due to the imbalance in the dataset. Results: Of the 933 patients included in this study, 538 (54%) were male with a median age of 8.97 years and interquartile range (1.81-15.0 yr). The ICU mortality was 35% and hospital mortality was 37%. The RF had the best performance for predicting ICU mortality (AUROC, 0.791 and AUPRC, 0.878) and LR for hospital mortality (AUROC, 0.777 and AUPRC, 0.859). The top two predictors of ICU survival were Pediatric Logistic Organ Dysfunction-2 score at CRRT initiation and admission diagnosis of respiratory failure. Conclusions: These are the first ML models to predict survival at ICU and hospital discharge in children and young adults receiving CRRT. RF outperformed other models for predicting ICU mortality. Future studies should expand the input variables, conduct a more sophisticated feature selection, and use deep learning algorithms to generate more precise models.Item Meta-analysis of ICU Delirium Biomarkers and Their Alignment With the NIA-AA Research Framework(American Association of Critical-Care Nurses, 2021) Chan, Carol K.; Song, Yiqing; Greene, Ryan; Lindroth, Heidi; Khan, Sikandar; Rios, Gabriel; Khan, Babar; Wang, Sophia; Psychiatry, School of MedicineBackground: Between 30% and 80% of survivors of critical illness experience cognitive impairment, but the underlying mechanisms remain unknown. Objective: To determine whether intensive care unit (ICU) delirium biomarkers align with the National Institute on Aging-Alzheimer's Association (NIA-AA) research framework for diagnostic biomarkers for Alzheimer disease and other related dementias (ADRD). Methods: Ovid MEDLINE, PsycInfo, Embase, and the Cochrane Library were systematically searched for articles published between January 1, 2000, and February 20, 2020, on the relationship between delirium and biomarkers listed in the NIA-AA framework. Only studies that addressed delirium in the ICU setting and fluid biomarkers were included in these analyses. Results: Of 61 256 records screened, 38 studies met inclusion criteria, 8 of which were suitable for meta-analysis. In pooled analysis, significant associations were found between ICU delirium and amyloid β-peptide 1-40 (standard mean difference [SMD], 0.42; 95% CI, 0.09-0.75), interleukin (IL)-1 receptor antagonist (SMD, 0.58; 95% CI, 0.21-0.94), and IL-6 (SMD, 0.31; 95% CI, 0.06-0.56). No significant association was observed in pooled analyses between ICU delirium and the other biomarkers. Few studies have examined ICU delirium and pathologic tau or neurodegeneration biomarkers. Conclusions: Inflammatory biomarkers and amyloid β are associated with ICU delirium and point to potential overlapping mechanisms between delirium and ADRD. Critical care providers should consider integrating diagnostic approaches used in ADRD in their assessment of post-ICU cognitive dysfunction.Item Minimizing Post–Intensive Care Syndrome to Improve Outcomes for Intensive Care Unit Survivors(American Association of Critical-Care Nurses, 2022) Mulkey, Malissa A.; Beacham, Pamela; McCormick, Megan A.; Everhart, D. Erik; Khan, Babar; Medicine, School of MedicineTopic: Post-intensive care syndrome is a collection of symptoms that more than half of patients who survive a critical illness, and their family caregivers, experience after the illness. Those symptoms include weakness/ fatigue, sleep disturbances/insomnia, cognitive dysfunction, posttraumatic stress disorder, other mental health conditions, and a lack of effective coping strategies. Clinical relevance: To minimize the risk of a patient developing post-intensive care syndrome, intensive care unit nurses must adopt practices that reduce the severity of disability and optimize patient outcomes. They must also advocate for patients who need additional expert care. Purpose: To describe interventions that critical care nurses can implement to minimize a patient's risk for post-intensive care syndrome. Content covered: This article describes patients who have a high risk of developing post-intensive care syndrome and interventions that are within nurses' purview.Item Mobile Critical Care Recovery Program for Survivors of Acute Respiratory Failure: A Randomized Clinical Trial(American Medical Association, 2024-01-02) Khan, Babar A.; Perkins, Anthony J.; Khan, Sikandar Hayat; Unverzagt, Frederick W.; Lasiter, Sue; Gao, Sujuan; Wang, Sophia; Zarzaur, Ben L.; Rahman, Omar; Eltarras, Ahmed; Qureshi, Hadi; Boustani, Malaz A.; Medicine, School of MedicineImportance: Over 50% of Acute Respiratory Failure (ARF) survivors experience cognitive, physical, and psychological impairments that negatively impact their quality of life (QOL). Objective: To evaluate the efficacy of a post-intensive care unit (ICU) program, the Mobile Critical Care Recovery Program (m-CCRP) consisting of a nurse care coordinator supported by an interdisciplinary team, in improving the QOL of ARF survivors. Design, setting, and participants: This randomized clinical trial with concealed outcome assessments among ARF survivors was conducted from March 1, 2017, to April 30, 2022, with a 12-month follow-up. Patients were admitted to the ICU services of 4 Indiana hospitals (1 community, 1 county, 2 academic), affiliated with the Indiana University School of Medicine. Intervention: A 12-month nurse-led collaborative care intervention (m-CCRP) supported by an interdisciplinary group of clinicians (2 intensivists, 1 geriatrician, 1 ICU nurse, and 1 neuropsychologist) was compared with a telephone-based control. The intervention comprised longitudinal symptom monitoring coupled with nurse-delivered care protocols targeting cognition, physical function, personal care, mobility, sleep disturbances, pain, depression, anxiety, agitation or aggression, delusions or hallucinations, stress and physical health, legal and financial needs, and medication adherence. Main outcomes and measures: The primary outcome was QOL as measured by the 36-item Medical Outcomes Study Short Form Health Survey (SF-36) physical component summary (PCS) and mental component summary (MCS), with scores on each component ranging from 0-100, and higher scores indicating better health status. Results: In an intention-to-treat analysis among 466 ARF survivors (mean [SD] age, 56.1 [14.4] years; 250 [53.6%] female; 233 assigned to each group), the m-CCRP intervention for 12 months did not significantly improve the QOL compared with the control group (estimated difference in change from baseline between m-CCRP and control group: 1.61 [95% CI, -1.06 to 4.29] for SF-36 PCS; -2.50 [95% CI, -5.29 to 0.30] for SF-36 MCS. Compared with the control group, the rates of hospitalization were higher in the m-CCRP group (117 [50.2%] vs 95 [40.8%]; P = .04), whereas the 12-month mortality rates were not statistically significantly lower (24 [10.3%] vs 38 [16.3%]; P = .05). Conclusions and relevance: Findings from this randomized clinical trial indicated that a nurse-led 12-month comprehensive interdisciplinary care intervention did not significantly improve the QOL of ARF survivors after ICU hospitalization. These results suggest that further research is needed to identify specific patient groups who could benefit from tailored post-ICU interventions.
