First-Line Respiratory Support for Children With Hematologic Malignancy and Acute Respiratory Failure.

OBJECTIVES: To characterize trends in noninvasive ventilation (NIV) and invasive mechanical ventilation (IMV) use over time in children with hematologic malignancy admitted to the PICU with acute respiratory failure (ARF), and to identify risk factors associated with NIV failure requiring transition to IMV. DESIGN: Retrospective cohort analysis using the Virtual Pediatric Systems (VPS, LLC) between January 1, 2010 and December 31, 2019. SETTING: One hundred thirteen North American PICUs participating in VPS. PATIENTS: Two thousand four hundred eighty children 0-21 years old with hematologic malignancy admitted to participating PICUs for ARF requiring respiratory support. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: There were 3013 total encounters, of which 868 (28.8%) received first-line NIV alone (NIV only), 1544 (51.2%) received first-line IMV (IMV only), and 601 (19.9%) required IMV after a failed NIV trial (NIV failure). From 2010 to 2019, the NIV only group increased from 9.6% to 43.1% and the IMV only group decreased from 80.1% to 34.2% (p < 0.001). The NIV failure group had the highest mortality compared with NIV only and IMV only (36.6% vs. 8.1%, vs. 30.5%, p < 0.001). However, risk-of-mortality (ROM) was highest in the IMV only group compared with NIV only and NIV failure (median Pediatric Risk of Mortality III ROM 8.1% vs. 2.8% vs. 5.5%, p < 0.001). NIV failure patients also had the longest median PICU length of stay compared with the other two study groups (15.2 d vs. 6.1 and 9.0 d, p < 0.001). Higher age was associated with significantly decreased odds of NIV failure, and diagnosis of non-Hodgkin lymphoma was associated with significantly increased odds of NIV failure compared with acute lymphoid leukemia. CONCLUSIONS: For children with hematologic malignancy admitted to the PICU with ARF, NIV has replaced IMV as the most common initial therapy. NIV failure rate remains high with high-observed mortality despite lower PICU admission ROM.

Machine learning models to predict and benchmark PICU length of stay with application to children with critical bronchiolitis.

OBJECTIVE: To create models for prediction and benchmarking of pediatric intensive care unit (PICU) length of stay (LOS) for patients with critical bronchiolitis. HYPOTHESIS: We hypothesize that machine learning models applied to an administrative database will be able to accurately predict and benchmark the PICU LOS for critical bronchiolitis. DESIGN: Retrospective cohort study. PATIENTS: All patients less than 24-month-old admitted to the PICU with a diagnosis of bronchiolitis in the Pediatric Health Information Systems (PHIS) Database from 2016 to 2019. METHODOLOGY: Two random forest models were developed to predict the PICU LOS. Model 1 was developed for benchmarking using all data available in the PHIS database for the hospitalization. Model 2 was developed for prediction using only data available on hospital admission. Models were evaluated using R2 values, mean standard error (MSE), and the observed to expected ratio (O/E), which is the total observed LOS divided by the total predicted LOS from the model. RESULTS: The models were trained on 13,838 patients admitted from 2016 to 2018 and validated on 5254 patients admitted in 2019. While Model 1 had superior R2 (0.51 vs. 0.10) and (MSE) (0.21 vs. 0.37) values compared to Model 2, the O/E ratios were similar (1.18 vs. 1.20). Institutional median O/E (LOS) ratio was 1.01 (IQR 0.90-1.09) with wide variability present between institutions. CONCLUSIONS: Machine learning models developed using an administrative database were able to predict and benchmark the length of PICU stay for patients with critical bronchiolitis.

Epidemiology of Pediatric Critical Care Admissions in 43 United States Children's Hospitals, 2014-2019.

OBJECTIVES: To identify trends in the population of patients in PICUs over time. DESIGN: Cross-sectional, retrospective cohort study using the Pediatric Health Information System database. SETTING: Forty-three U.S. children's hospitals. PATIENTS: All patients admitted to Pediatric Health Information System-participating hospitals from January 2014 to December 2019. Individuals greater than 65 years old and normal newborns were excluded. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: PICU care occurred in 13.8% of all pediatric hospital encounters and increased over the study period from 13.3% to 14.3%. Resource intensity, based on average Hospitalization Resource Intensity Scores for Kids score, increased significantly across epochs (6.5 in 2014-2015 vs 6.9 in 2018-2019; p < 0.001), although this was not consistently manifested as additional procedural exposure. Geometric mean PICU cost per patient encounter was stable. The two most common disease categories in PICU patients were respiratory failure and cardiac and circulatory congenital anomalies. Of all PICU encounters, 35.5% involved mechanical ventilation, and 25.9% involved vasoactive infusions. Hospital-level variation in the percentage of days spent in the PICU ranged from 15.1% to 63.5% across the participating sites. Of the total hospital costs for patients admitted to the PICU, 41.7% of costs were accrued during the patients' PICU stay. CONCLUSIONS: The proportional use of PICU beds is increasing over time, although was variable across centers. Case-based resource use and complexity of pediatric patients are also increasing. Despite the higher use of PICU resources, the standardized costs of PICU care per patient encounter have remained stable. These data may help to inform current PICU resource allocation and future PICU capacity planning.

Mortality and PICU Hospitalization Among Pediatric Gunshot Wound Victims in Chicago.

Firearm injury accounts for significant morbidity with high mortality among children admitted to the PICU. Understanding risk factors for PICU admission is an important step toward developing prevention and intervention strategies to minimize the burden of pediatric gunshot wound (GSW) injury. OBJECTIVES: The primary objective of this study was to characterize outcomes and the likelihood of PICU admission among children with GSWs. DESIGN SETTING AND PARTICIPANTS: Retrospective cohort study of GSW patients 0-18 years old evaluated at the University of Chicago Comer Children's Hospital Pediatric Trauma Center from 2010 to 2017. MAIN OUTCOMES AND MEASURES: Demographic and injury severity measures were acquired from an institutional database. We describe mortality and hospitalization characteristics for the cohort. We used logistic regression models to test the association between PICU admission and patient characteristics. RESULTS: During the 8-year study period, 294 children experienced GSWs. We did not observe trends in overall mortality over time, but mortality for children with GSWs was higher than all-cause PICU mortality. Children 0-6 years old experienced longer hospitalizations compared with children 13-16 years old (5 vs 3 d; p = 0.04) and greater frequency of PICU admission (83.3% vs 52.9%; p = 0.001). Adjusting for severity of illness, children less than 7 years old were four-fold more likely to be admitted to the PICU than children 13-16 years old (aOR range, 3.9-4.6). CONCLUSIONS AND RELEVANCE: Despite declines in pediatric firearm mortality across the United States, mortality did not decrease over time in our cohort and was higher than all-cause PICU mortality. Younger children with GSWs experience longer hospitalizations and require PICU care more often than older children. Our findings suggest that the youngest victims of firearm-related injury may be particularly at-risk of the long-term sequelae of critical illness and injury.

Education and Visual Reminders Fail to Reduce Overuse and Waste in Interhospital Transfers to a Pediatric Intensive Care Unit.

INTRODUCTION: As healthcare costs continue to rise, initiatives to reduce costs while maintaining high-quality care become a priority. Nonclinically indicated studies add to this cost, especially during interfacility transfers when studies are often repeated. Also, unnecessary evaluations add to nonmonetary costs such as pain, radiation exposure, and iatrogenic anemia. This study aimed to establish the frequency of redundant testing on interfacility transfers to the pediatric intensive care unit (PICU) and then implement an education-based quality improvement strategy for waste reduction. METHODS: In the preintervention period (September 2018-February 2019), we collected data on patients transferred to the PICU from any outside facility. Investigators evaluated studies repeated within 6 hours and deemed them redundant or indicated. We then determined a rate of patients with redundant studies as the first aim. This result prompted an educational intervention focused on testing stewardship. Investigators then collected data in the postintervention period (July-December 2019) and compared the rate of redundant studies. RESULTS: Study efforts identified 150 patients in the preintervention period and 131 in the postintervention period, establishing a 21%-25% frequency of redundant testing. Education and visual reminders failed to reduce this testing. CONCLUSION: This study established a baseline rate of redundant testing on transferred patients to the PICU. An educational intervention alone did not produce significant change.

Medication Adherence Reminder System for Virtual Home Assistants: Mixed Methods Evaluation Study.

BACKGROUND: Medication nonadherence is a global public health challenge that results in suboptimal health outcomes and increases health care costs. Forgetting to take medicines is one of the most common reasons for unintentional medication nonadherence. Research findings indicate that voice-activated virtual home assistants, such as Amazon Echo and Google Home devices, may be useful in promoting medication adherence. OBJECTIVE: This study aims to create a medication adherence app (skill), MedBuddy, for Amazon Echo devices and measure the use, usability, and usefulness of this medication-taking reminder skill. METHODS: A single-group, mixed methods, cohort feasibility study was conducted with women who took oral contraceptives (N=25). Participants were undergraduate students (age: mean 21.8 years, SD 6.2) at an urban university in the Southeast United States. Participants were given an Amazon Echo Dot with MedBuddy-a new medication reminder skill for Echo devices created by our team-attached to their study account, which they used for 60 days. Participants self-reported their baseline and poststudy medication adherence. MedBuddy use was objectively evaluated by tracking participants' interactions with MedBuddy through Amazon Alexa. The usability and usefulness of MedBuddy were evaluated through a poststudy interview in which participants responded to both quantitative and qualitative questions. RESULTS: Participants' interactions with MedBuddy, as tracked through Amazon Alexa, only occurred on half of the study days (mean 50.97, SD 29.5). At study end, participants reported missing their medication less in the past 1 and 6 months compared with baseline (χ21=0.9 and χ21=0.4, respectively; McNemar test: P<.001 for both). However, there was no significant difference in participants' reported adherence to consistently taking medication within the same 2-hour time frame every day in the past 1 or 6 months at the end of the study compared with baseline (χ21=3.5 and χ21=0.4, respectively; McNemar test: P=.63 and P=.07, respectively). Overall feedback about usability was positive, and participants provided constructive feedback about the skill's features that could be improved. Participants' evaluation of MedBuddy's usefulness was overwhelmingly positive-most (15/23, 65%) said that they would continue using MedBuddy as a medication reminder if provided with the opportunity and that they would recommend it to others. MedBuddy features that participants enjoyed were an external prompt separate from their phone, the ability to hear the reminder prompt from a separate room, multiple reminders, and verbal responses to prompts. CONCLUSIONS: The findings of this feasibility study indicate that the MedBuddy medication reminder skill may be useful in promoting medication adherence. However, the skill could benefit from further usability enhancements.

Resources and Costs Associated With Repeated Admissions to PICUs.

OBJECTIVE: To determine the costs and hospital resource use from all PICU patients readmitted with a PICU stay within 12 months of hospital index discharge. DESIGN: Cross-sectional, retrospective cohort study using Pediatric Health Information System. SETTING: Fifty-two tertiary children's hospitals. SUBJECTS: Pediatric patients under 18 years old admitted to the PICU from January 1, 2016, to December 31, 2017. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patient characteristics and costs of care were compared between those with readmission requiring PICU care and those with only a single PICU admission per annum. In this 2-year cohort, there were 239,157 index PICU patients of which 36,970 (15.5%) were readmitted and required PICU care during the 12 months following index admission. The total hospital cost for all index admissions and readmissions was $17.3 billion, of which 21.5% ($3.71 billion) were incurred during a readmission stay involving care in the PICU; of the 3,459,079 hospital days, 20.3% (702,200) were readmission days including those where PICU care was required. Of the readmitted patients, 11,703 (30.0%) received only PICU care, accounting for $662 million in costs and 110,215 PICU days. Although 43.6% of all costs were associated with patients who required readmission, these patients only accounted for 15.5% of the index patients and 28% of index hospitalization expenditures. More patients in the readmitted group had chronic complex conditions at index discharge compared with those not readmitted (83.9% vs 54.9%; p < 0.001). Compared with those discharged directly to home without home healthcare, patients discharged to a skilled nursing facility had 18% lower odds of readmission (odds ratio 0.82 [95% CI, 0.75-0.89]; p < 0.001) and those discharged home with home healthcare had 43% higher odds of readmission (odds ratio, 1.43 [95% CI, 1.36-1.51]; p < 0.001). CONCLUSIONS: Repeated admissions with PICU care resulted in significant direct medical costs and resource use for U.S. children's hospitals.

Choosing Wisely For Critical Care: The Next Five.

OBJECTIVES: To formulate new "Choosing Wisely" for Critical Care recommendations that identify best practices to avoid waste and promote value while providing critical care. DATA SOURCES: Semistructured narrative literature review and quantitative survey assessments. STUDY SELECTION: English language publications that examined critical care practices in relation to reducing cost or waste. DATA EXTRACTION: Practices assessed to add no value to critical care were grouped by category. Taskforce assessment, modified Delphi consensus building, and quantitative survey analysis identified eight novel recommendations to avoid wasteful critical care practices. These were submitted to the Society of Critical Care Medicine membership for evaluation and ranking. DATA SYNTHESIS: Results from the quantitative Society of Critical Care Medicine membership survey identified the top scoring five of eight recommendations. These five highest ranked recommendations established Society of Critical Care Medicine's Next Five "Choosing" Wisely for Critical Care practices. CONCLUSIONS: Five new recommendations to reduce waste and enhance value in the practice of critical care address invasive devices, proactive liberation from mechanical ventilation, antibiotic stewardship, early mobilization, and providing goal-concordant care. These recommendations supplement the initial critical care recommendations from the "Choosing Wisely" campaign.

Terbutaline and aminophylline as second-line therapies for status asthmaticus in the pediatric intensive care unit.

OBJECTIVE: Asthma is the most common chronic disease of childhood. Although asthma admissions to the pediatric intensive care unit (PICU) are increasing, there are no evidence-based guidelines on preferred escalation of therapies for patients with status asthmaticus who fail to respond to inhaled bronchodilators and systemic corticosteroids. The purpose of this study was to assess outcomes of PICU patients receiving aminophylline versus terbutaline as second-tier therapies for status asthmaticus. DESIGN: Retrospective cohort study using Pediatric Health Information System from 2016-2019. SETTING: Fifty-three tertiary children's hospitals. SUBJECTS: Children aged 2 to 18 years admitted to the PICU in children's hospitals contributing data to the Pediatric Health Information System with a primary diagnosis of status asthmaticus. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 11 133 pediatric patients treated for status asthmaticus in the PICU during the study period, 1144 received either terbutaline or aminophylline. There was no difference in intubation and mechanical ventilation between patients who received aminophylline and those who received terbutaline. However, in African American patients, those who received terbutaline had a significantly higher odds of intubation and mechanical ventilation compared to those who received aminophylline (OR, 12.41; 95%CI, 1.61,95). CONCLUSIONS: The use of aminophylline is associated with lower odds of intubation and mechanical ventilation in African American patients with status asthmaticus as compared to terbutaline.

Fluid Overload in Pediatric Severe Traumatic Brain Injury.

OBJECTIVE: Pediatric traumatic brain injury is a major public health problem in the United States. Hypertonic saline therapy is a well-established treatment in patients with severe traumatic brain injury (Glasgow Coma Scale ≤ 8) who have intracranial hypertension. In children, fluid overload is associated with increased mortality, ventilator duration, and length of PICU stay, even when controlling for severity of illness. This study reports prevalence of fluid overload in pediatric patients with severe traumatic brain injury treated with 3% hypertonic saline and effect on clinical outcomes. DESIGN: Single-center retrospective chart review. SETTING: PICUs at two tertiary children's hospitals. PATIENTS: One hundred thirty-eight patients with traumatic brain injury with postresuscitation Glasgow Coma Scale less than or equal to 8 who received hypertonic saline from September 1, 2010, to February 28, 2016, and intracranial pressure monitoring and survived at least 24 hours from admission. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We used fluid balance percentage greater than or equal to 10% as our definition of fluid overload. Ninety-one percent of patients less than 1 year old had fluid overload on day 10 of admission compared with 47% of patients greater than 1 year. Fluid overloaded patients did not have increased mortality, acute kidney injury, PICU length of stay, or ventilator days. Hypertonic saline was not the cause of fluid overload in these patients. CONCLUSIONS: Patients with severe traumatic brain injury do have high rates of fluid overload. However, fluid overload did not contribute to mortality, longer days on the ventilator, increased risk of acute kidney injury, or increased PICU length of stay.

The Fragility of Statistically Significant Findings in Pediatric Critical Care Randomized Controlled Trials.

OBJECTIVES: The Fragility Index measures the number of events on which the statistical significance of a result depends and has been suggested as an adjunct statistical assessment for interpretation of trial results. This study aimed to assess the robustness of statistically significant results from pediatric critical care randomized controlled trials with dichotomous outcomes. DATA SOURCES: A previously published scoping review of pediatric critical care randomized controlled trials (www.PICUtrials.net). STUDY SELECTION: A total of 342 trials were screened for inclusion. After applying inclusion/exclusion criteria, 43 fulfilled eligibility criteria and were included in the analysis. DATA EXTRACTION: Calculation of Fragility Index for trials reporting a statistically significant dichotomous outcome, and analysis of the relationship between trial characteristics and Fragility Index. DATA SYNTHESIS: The median Fragility Index was 2 (interquartile range, 1-6). The median sample size was 98 (interquartile range, 50-148) and sample size demonstrated a strong correlation with the Fragility Index (r = 0.729; n = 43; p < 0.001). The median number of outcome events was 8 (interquartile range, 4-15) and the total number of outcome events also showed a strong correlation with the Fragility Index (r = 0.728; n = 43; p < 0.001). CONCLUSIONS: Results from pediatric critical care randomized controlled trials with dichotomous outcomes reporting statistically significant findings often hinge on a small number of outcome events. Clinicians should exercise caution when interpreting results of trials with a low Fragility Index.

Acquired Cardiac Disease in the Pediatric Intensive Care Unit.

This review focuses on the identification, evaluation, management, and stabilization of a variety of acquired cardiac conditions, such as cardiomyopathies, inflammatory cardiac disease, and Kawasaki disease, which commonly require care in the pediatric intensive care unit (PICU). Pediatric cardiomyopathies comprise a spectrum of acquired or congenital myocardial diseases in which there are abnormalities of cardiac size and ventricular wall thickness, along with ventricular performance. The inflammatory diseases of the heart include acute myocarditis and pericarditis. Cardiac sequelae of Kawasaki disease resemble a self-limited vasculitis, but in rare instances may present with hemodynamic instability requiring vasopressor support. Care in the PICU affords both monitoring and management opportunities. [Pediatr Ann. 2018;47(7):e280-e285.].

Opioid-Related Critical Care Resource Use in US Children's Hospitals.

BACKGROUND AND OBJECTIVES: There has been a rapid increase in the rate of pediatric opioid-related hospitalizations. It is unknown how this increase has impacted the use of pediatric critical care. Our objective in this study was to assess the trends in pediatric hospitalization for opioid ingestions in a cohort of US children's hospitals and, specifically, to evaluate the impact on pediatric critical care resource use. METHODS: A retrospective cohort study of the Pediatric Health Information System was performed to identify hospitalizations for opioid ingestions from 2004 to 2015. Admission to the PICU and the use of naloxone, vasopressors, and ventilation were assessed by using billing data. The primary outcome measure was the trend in the rate of PICU admission for opioid-related ingestion over time, assessed by using Poisson regression. RESULTS: There were 3647 opioid-related hospitalizations in 31 hospitals; 42.9% required PICU care. The overall mortality was 1.6%, with annual deaths decreasing from 2.8% to 1.3% (P < .001). The number of opioid-related hospitalizations requiring PICU care doubled between 2004 and 2015. The rate of PICU admission for opioid-related hospitalization increased significantly, from 24.9 to 35.9 per 10 000 PICU admissions (P < .001). Among PICU admissions, 37.0% required mechanical ventilator support, and 20.3% required vasopressors. CONCLUSIONS: The US opioid crisis is negatively impacting children, and the rate of hospitalization and PICU admission for pediatric opioid ingestions is increasing. Current efforts to reduce adult opioid use have not curtailed the incidence of pediatric opioid ingestions, and additional efforts are needed to reduce preventable opioid exposure in children.

The Fragility Index in a Cohort of Pediatric Randomized Controlled Trials.

Data suggest inadequacy of common statistical techniques for reporting outcomes in clinical trials. The Fragility Index can measure how many events the statistical significance hinges on, and may facilitate better interpretation of trial results. This study aimed to assess the Fragility Index in pediatric randomized controlled trials (RCTs) with statistically significant findings published in high-quality medical journals. A Fragility Index was calculated on included trials with dichotomous positive outcomes. Analysis of the relationship between trial characteristics and the Fragility Index was performed. Of the 429 abstracts screened, 17 met the inclusion criteria and underwent analysis. The median Fragility Index was 7 with an interquartile range of 2-11. In 41% of the studies, the number of patients lost to follow-up or withdrawn prior to analysis was equal to or greater than the Fragility Index. There was no correlation between the RCT sample size and the Fragility Index (r = 0.249, p = 0.335) nor the event group size and the Fragility Index (r = 0.250, p = 0.334). There was a strong negative correlation between the original p-value and the Fragility Index (r = -0.700, p = 0.002). The Fragility Index is a calculated metric that may assist in applying clinical relevance to statistically significant outcomes in pediatric randomized controlled trials with dichotomous outcomes.

WE CARE 4 KIDS: Use of a Rounding Tool in the Pediatric Intensive Care Unit.

OBJECTIVE: To implement a daily rounding tool in a pediatric intensive care unit (PICU) to improve the discussion performance of identified clinical elements. We hypothesized that a semi-structured rounding tool created by a multidisciplinary team would be successfully implemented and sustained in the PICU. PATIENTS AND METHODS: A pre-post interventional study was conducted in a multidisciplinary medical-surgical PICU. Baseline data collection of undisclosed clinical elements was performed by covert observers, which resulted in the development of a comprehensive, nurse-driven rounding checklist. Frequencies of pre- and postintervention metrics were assessed after implementation, and sustainability was assessed at 5 years. RESULTS: Six months after implementation, 70% (7/10) of checklist elements demonstrated significant improvement. Five years after implementation, 172 of a possible 222 (74%) checklists were collected. Eighty percentage (8/10) of the measures sustained discussion frequency after 5 years of use. Nursing presence significantly improved at year 5 compared with the preimplementation period. Nursing satisfaction surveys distributed at year 5 showed that the rounding tool was useful and nurses were confident in understanding care plans at the end of rounds. Ninety-eight percentage of checklists revealed discrete transcription of qualitative daily goals. CONCLUSIONS: A semi-structured rounding tool created by a multidisciplinary team was successfully implemented, and performance was sustained at 5 years. This initiative led to improved bedside nursing presence during patient care rounds.

The Effect of a Pediatric Intensive Care Severity-Tiered Pathway for Status Asthmaticus on Quality Measures and Outcomes.

Background: Patients with status asthmaticus admitted to the hospital contribute tremendous costs to the healthcare system. Treatment protocols directed at improving care to pediatric inpatients have improved both clinical and financial outcomes; however, there are limited data demonstrating the impact of goal-driven therapy for patients with status asthmaticus in the pediatric intensive care unit (PICU). The purpose of this initiative was to standardize care of children with status asthmaticus in the PICU to improve clinical outcomes. Materials and Methods: A goal-directed clinical pathway using a validated pediatric asthma severity score was developed. A pre-post intervention assessed patients 2-17 years of age admitted to the PICU with status asthmaticus. The effect of the protocol was measured from October 2015 to October 2016. The primary outcome was the transition time interval from continuous nebulized bronchodilator therapy to every 2 hourly intermittent treatments. Secondary outcomes related to treatment options and clinical complications were also assessed. Results: Postintervention patient (n = 124) demographics were similar to those in the preintervention group (n = 130). Compared with baseline, there was a 4.9-h decrease in the mean transition time from continuous to intermittent bronchodilator use (31.9 versus 27.0, P = 0.033) following the intervention. The mean and median hospital length of stay (LOS) was significantly decreased in the postintervention group by 14.76 h (P = 0.011) and 16.68 h (P = 0.003). There were no readmissions to the PICU in the postintervention group. The use of rescue BiPAP (Bi-level positive airway pressure ventilation) was significantly higher in the preintervention group compared with the postintervention group (42% versus 28%, P = 0.036). Conclusions: A severity-tiered, goal-driven treatment pathway for pediatric patients admitted to the PICU with status asthmaticus reduced the time required to transition from continuous to intermittent inhaled bronchodilator use. As a result, overall hospital LOS was significantly decreased with no increase in clinical complications.
