Prevalence of Children With Complex Chronic Conditions in PICUs of Argentina: A Prospective Multicenter Study

How are children with medical complexity being identified in epidemiological studies? A systematic review

BACKGROUND

There are different definitions to identify/classify children with medical complexity (CMC). We aimed to investigate and describe the definitions used to classify CMC in epidemiological studies.

METHODS

PubMed, SciELO, LILACS, and EMBASE were searched from 2015 to 2020 (last updated September 15th, 2020) for original studies that presented the definition used to classify/identify CMC in the scientific research method. We applied the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. From the included studies, the following were identified: first author, year of publication, design, population, study period, the definition of CMC used, limitations, and strengths.

RESULTS

Nine hundred and sixty-seven records were identified in the searched databases, and 42 met the inclusion criteria. Of the 42 studies included, the four most frequent definitions used in the articles included in this review were classification of CMC into nine diagnostic categories based on the International Classification of Diseases, Ninth Revision (ICD-9) (35.7%, 15 articles); update of the previous classification for ICD-10 codes with the inclusion of other conditions in the definition (21.4%, nine articles); definition based on a medical complexity algorithm for classification (16.7%, seven articles); and a risk rating system (7.1%, three articles).

CONCLUSIONS

CMC definitions using diagnostic codes were more frequent. However, several limitations were found in its uses. Our research highlighted the need to improve health information systems to accurately characterize the CMC population and promote the provision of comprehensive care.

Development and preliminary validation of the Sleep Screening for Children and Adolescents with Complex Chronic Conditions (SCAC)

Children and adolescents with complex chronic conditions, including those with life-threatening or life-limiting conditions, are a heterogeneous population. Many individuals exhibit sleep abnormalities that are measurable by proxy questionnaires. No suitable instrument to assess the wide range of different complex chronic conditions is currently available. The aim of the present study was to develop a screening tool-the Sleep Screening for Children and Adolescents with Complex Chronic Conditions-to effectively obtain sleep behaviour information in this population. Following a mixed-method design, potential items for the Sleep Screening for Children and Adolescents with Complex Chronic Conditions questionnaire were defined through literature research and expert meetings. In a pre-test with N = 60 family and professional caregivers, the items' relevance and comprehensibility as well as the instrument's overall design were assessed. For the main test, N = 315 participants were recruited in three tertiary paediatric hospitals. A principal components analysis detected the questionnaire's scales. Item analysis focused on mean values, range, difficulty and discriminatory power. Convergent validation of the Sleep Screening for Children and Adolescents with Complex Chronic Conditions was assessed via correlations between scale items. Most patients had neurological or neuromuscular diseases. Four scales ("Falling and staying asleep", "Sleep-associated respiration and arousal", "Daytime sleepiness" and "Sleep-associated movements") emerged. The item analysis showed satisfactory discriminative power. In the preliminary validation, all scales correlated positively with a child's care level and with various sleep circumstances items. Three scales additionally correlated with the number of complex chronic condition diagnoses. This newly developed questionnaire can provide clinicians with first indications of possible sleep problems in a growing paediatric population.

Factors associated with survival and neurologic outcome after in-hospital cardiac arrest in children: A cohort study

Aim

In-hospital paediatric cardiopulmonary resuscitation (CPR) survival has been improving in high-income countries. This study aimed to analyse factors associated with survival and neurological outcome after paediatric CPR in a middle-income country.

Methods

This observational study of in-hospital cardiac arrest using Utstein-style registry included patients <18 years old submitted to CPR between 2015 and 2020, at a high-complexity hospital. Outcomes were survival and neurological status assessed using Paediatric Cerebral Performance Categories score at prearrest, discharge, and after 180 days.

Results

Of 323 patients who underwent CPR, 108 (33.4%) survived to discharge and 93 (28.8%) after 180 days. In multivariable analysis, lower survival at discharge was associated with liver disease (OR 0.060, CI 0.007-0.510, p = 0.010); vasoactive drug infusion before cardiac arrest (OR 0.145, CI 0.065-0.325, p < 0.001); shock as the immediate cause (OR 0.183, CI 0.069-0.486, p = 0.001); resuscitation > 30 min (OR 0.070, CI 0.014-0.344, p = 0.001); and bicarbonate administration during CPR (OR 0.318, CI 0.130-0.780, p = 0.01). The same factors remained associated with lower survival after 180 days. Neurological outcome was analysed in the 93 survivors after 180 days following CPR. Prearrest neurological dysfunction was observed in 31.4%, and neurological prognosis was favourable in 79.7% at discharge and similar after 180 days.

Conclusion

In-hospital paediatric cardiac arrest patients with complex chronic conditions had lower survival associated with liver disease, shock as cause of cardiac arrest, vasoactive drug infusion before cardiac arrest, bicarbonate administration during CPR, and prolonged resuscitation. Most survivors had favourable neurological outcome.

Defining Pediatric Chronic Critical Illness: A Scoping Review

OBJECTIVES

Children with chronic critical illness (CCI) are hypothesized to be a high-risk patient population with persistent multiple organ dysfunction and functional morbidities resulting in recurrent or prolonged critical care; however, it is unclear how CCI should be defined. The aim of this scoping review was to evaluate the existing literature for case definitions of pediatric CCI and case definitions of prolonged PICU admission and to explore the methodologies used to derive these definitions.

DATA SOURCES

Four electronic databases (Ovid Medline, Embase, CINAHL, and Web of Science) from inception to March 3, 2021.

STUDY SELECTION

We included studies that provided a specific case definition for CCI or prolonged PICU admission. Crowdsourcing was used to screen citations independently and in duplicate. A machine-learning algorithm was developed and validated using 6,284 citations assessed in duplicate by trained crowd reviewers. A hybrid of crowdsourcing and machine-learning methods was used to complete the remaining citation screening.

DATA EXTRACTION

We extracted details of case definitions, study demographics, participant characteristics, and outcomes assessed.

DATA SYNTHESIS

Sixty-seven studies were included. Twelve studies (18%) provided a definition for CCI that included concepts of PICU length of stay (n = 12), medical complexity or chronic conditions (n = 9), recurrent admissions (n = 9), technology dependence (n = 5), and uncertain prognosis (n = 1). Definitions were commonly referenced from another source (n = 6) or opinion-based (n = 5). The remaining 55 studies (82%) provided a definition for prolonged PICU admission, most frequently greater than or equal to 14 (n = 11) or greater than or equal to 28 days (n = 10). Most of these definitions were derived by investigator opinion (n = 24) or statistical method (n = 18).

CONCLUSIONS

Pediatric CCI has been variably defined with regard to the concepts of patient complexity and chronicity of critical illness. A consensus definition is needed to advance this emerging and important area of pediatric critical care research.

Epidemiology and outcomes of septic shock in children with complex chronic conditions in a developing country PICU

OBJECTIVE

To investigate the role of Complex Chronic Conditions (CCCs) on the outcomes of pediatric patients with refractory septic shock, as well as the accuracy of PELOD-2 and Vasoactive Inotropic Score (VIS) to predict mortality in this specific population.

METHODS

This is a single-center, retrospective cohort study. All patients diagnosed with septic shock requiring vasoactive drugs admitted to a 13-bed PICU in southern Brazil, between January 2016 and July 2018, were included. Clinical and demographic characteristics, presence of CCCs and VIS, and PELOD-2 scores were accessed by reviewing electronic medical records. The main outcome was considered PICU mortality.

RESULTS

218 patients with septic shock requiring vasoactive drugs were identified in the 30-month period and 72% of them had at least one CCC. Overall mortality was 22%. Comparing to patients without previous comorbidities, those with CCCs had a higher mortality (26.7% vs 9.8%; OR = 3.4 [1.3-8.4]) and longer hospital length of stay (29.3 vs 14.8; OR 2.39 [1.1- 5.3]). Among the subgroups of CCCs, "Malignancy" was particularly associated with mortality (OR = 2.3 [1.0-5.1]). VIS and PELOD-2 scores in 24 and 48 hours were associated with mortality and a PELOD-2 in 48 hours > 8 had the best performance in predicting mortality in patients with CCC (AUROC = 0.89).

CONCLUSION

Patients with CCCs accounted for the majority of those admitted to the PICU with septic shock and related to poor outcomes. The high prevalence of hospitalizations, use of resources, and significant mortality determine that patients with CCCs should be considered a priority in the healthcare system.

Prevalence and functional status of children with complex chronic conditions in Brazilian PICUs during the COVID-19 pandemic

OBJECTIVE

The proportion of children with complex chronic conditions is increasing in PICUs around the world. We determined the prevalence and functional status of children with complex chronic conditions in Brazilian PICUs during the COVID-19 pandemic.

METHODS

The authors conducted a point prevalence cross-sectional study among fifteen Brazilian PICUs during the COVID-19 pandemic. The authors enrolled all children admitted to the participating PICUs with complex chronic conditions on three different days, four weeks apart, starting on April 4^th, 2020. The authors recorded the patient's characteristics and functional status at admission and discharge days.

RESULTS

During the 3 study days from March to June 2020, the authors enrolled 248 patients admitted to the 15 PICUs; 148 had CCC (prevalence of 59.7%). Patients had a median of 1 acute diagnosis and 2 chronic diagnoses. The use of resources/devices was extensive. The main mode of respiratory support was conventional mechanical ventilation. Most patients had a peripherally inserted central catheter (63.1%), followed by a central venous line (52.5%), and 33.3% had gastrostomy or/and tracheostomy. The functional status score was significantly better at discharge compared to admission day due to the respiratory status improvement.

CONCLUSIONS

The prevalence of children with CCC admitted to the Brazilian PICUs represented 59.7% of patients during the COVID-19 pandemic. The functional status of these children improved during hospitalization, mainly due to the respiratory component.

Telehealth in outpatient care for children and adolescents with chronic conditions during the COVID-19 pandemic: A scoping review protocol

INTRODUCTION

Outpatient care for children and adolescents with chronic conditions needs to be continuous and programmed, encompassing comprehensive care, with periodically scheduled consultations, exams, and procedures, to promote quality of life and reduce mortality. In the context of the new coronavirus pandemic, however, outpatient care for children and adolescents with chronic conditions, in person, was hampered in favor of social isolation, a necessary sanitary measure to reduce and prevent the spread of Coronavirus Disease 2019. In response to this need, studies suggest telehealth in pediatrics as a fertile and expanding field especially in times of pandemics. Here, we aimed to map the evidence related to telehealth in outpatient care for children and adolescents with chronic conditions during the COVID-19 pandemic, to identify which strategies were implemented and their impacts on the continuity of care.

METHODS

A scoping review protocol is reported and guided by the Scoping Reviews Manual of the Joanna Briggs Institute. The search for evidence will cover the following databases: MEDLINE/PubMed, Cochrane Libary; Embase; Web of Science; Scopus; Cinahl and PsycINFO, plus additional sources, such as The British Library, Google Scholar, and Preprints [medRXiv]. No date or language restrictions will be employed in this scoping review. Two independent researchers will conduct the search strategy, study selection, data charting, and data synthesis.

RESULTS

The findings will be presented through tables, charts, narrative summaries, and assessed based on the type of data charted as well as outcomes. Additionally, the meaning of these findings will be considered as they relate to the guiding question, the characterization and measurement of the impact of different telehealth modalities used in outpatient care for children and adolescents with chronic conditions during the COVID-19 pandemic, and the implications for practice and further research.

DISCUSSION

To the best of our knowledge, this will be the first scoping review to look specifically at the telehealth modalities to be used in outpatient care for children and adolescents with chronic conditions during the COVID-19 pandemic. We expect that our results will be of interest to practitioners as well as researchers concerned with this particular emerging issue in the pandemic context. Also, the plans for the dissemination of this study comprise peer-reviewed publication and conference presentations.

The Child With Severe Chronic Illness in the ICU: A Concise Review

OBJECTIVES

Children with severe chronic illness are a prevalent, impactful, vulnerable group in PICUs, whose needs are insufficiently met by transitory care models and a narrow focus on acute care needs. Thus, we sought to provide a concise synthetic review of published literature relevant to them and a compilation of strategies to address their distinctive needs.

DATA SOURCES

English language articles were identified in MEDLINE using a variety of phrases related to children with chronic conditions, prolonged admissions, resource utilization, mortality, morbidity, continuity of care, palliative care, and other critical care topics. Bibliographies were also reviewed.

STUDY SELECTION

Original articles, review articles, and commentaries were considered.

DATA EXTRACTION

Data from relevant articles were reviewed, summarized, and integrated into a narrative synthetic review.

DATA SYNTHESIS

Children with serious chronic conditions are a heterogeneous group who are growing in numbers and complexity, partly due to successes of critical care. Because of their prevalence, prolonged stays, readmissions, and other resource use, they disproportionately impact PICUs. Often more than other patients, critical illness can substantially negatively affect these children and their families, physically and psychosocially. Critical care approaches narrowly focused on acute care and transitory/rotating care models exacerbate these problems and contribute to ineffective communication and information sharing, impaired relationships, subpar and untimely decision-making, patient/family dissatisfaction, and moral distress in providers. Strategies to mitigate these effects and address these patients' distinctive needs include improving continuity and communication, primary and secondary palliative care, and involvement of families. However, there are limited outcome data for most of these strategies and little consensus on which outcomes should be measured.

CONCLUSIONS

The future of pediatric critical care medicine is intertwined with that of children with serious chronic illness. More concerted efforts are needed to address their distinctive needs and study the effectiveness of strategies to do so.

Characteristics and Outcomes of Children With Necrotizing Pneumonia

OBJECTIVES

In this study, we describe the characteristics and outcomes of pediatric necrotizing pneumonia in the United States.

DESIGN AND SETTING

A retrospective analysis of the Healthcare Cost and Utilization Project 2016 Kids Inpatient Database was performed. The Kids Inpatient Database is a large deidentified hospital discharge database of pediatric patients in the United States.

PATIENTS

The database was filtered using International Classification of Diseases, 10th Edition code J85.0 to identify necrotizing pneumonia in children 28 days to 20 years old.

INTERVENTIONS

Children with necrotizing pneumonia with and without bacterial isolation and with and without complex chronic conditions were compared. Sample weighting was employed to produce national estimates.

MEASUREMENTS AND MAIN RESULTS

Of the 2,296,220 discharges, 746 patients had necrotizing pneumonia (prevalence: 3.2/10,000 discharges). In patients with necrotizing pneumonia, 46.6% required chest tubes, 6.1% underwent video-assisted thoracoscopic surgery, and 27.6% were mechanically ventilated. Pneumothorax was identified in 16.7% and pyothorax in 27.4%. The overall mortality rate was 4.1% (n = 31). Bacterial isolation was documented in 40.9%. The leading organisms identified in patients without a complex chronic condition were Streptococcus pneumoniae (12.6%) and Staphylococcus aureus (9.2%) and in patients with a complex chronic condition were S. aureus (13.4%) and Pseudomonas aeruginosa (12.8%). Patients with bacterial isolation were significantly more likely to develop pneumothorax (odds ratio, 2.6; CI, 1.6-4.2) or septic shock (odds ratio, 3.2; CI, 1.9-5.4) and require a chest tube (odds ratio, 2.5; CI, 1.7-3.5) or mechanical ventilation (odds ratio, 2.3; CI, 1.5-3.3) than patients without bacterial isolation.

CONCLUSIONS

Bacterial etiology of necrotizing pneumonia in children varied with the presence or absence of a complex chronic condition. Bacterial isolation is associated with increased invasive procedures and complications. The mortality rate is higher in children with complex chronic conditions. This study provides national data on necrotizing pneumonia among hospitalized children.

Nutritional screening tool for critically ill children: a systematic review

CONTEXT

Nutritional screening tools (NSTs) are used to identify patients who are at risk of nutritional status (NS) deterioration and associated clinical outcomes. Several NSTs have been developed for hospitalized children; however, none of these were specifically developed for Pediatric Intensive Care Unit (PICU) patients.

OBJECTIVE

A systematic review of studies describing the development, application, and validation of NSTs in hospitalized children was conducted to critically appraise their role in PICU patients.

DATA SOURCES

PubMed, Embase, Web of Science, Scopus, SciELO, LILACS, and Google Scholar were searched from inception to December 11, 2020.

DATA EXTRACTION

The review included 103 studies that applied NSTs at hospital admission. The NST characteristics collected included the aims, clinical setting, variables, and outcomes. The suitability of the NSTs in PICU patients was assessed based on a list of variables deemed relevant for this population.

DATA ANALYSIS

From 19 NSTs identified, 13 aimed to predict NS deterioration. Five NSTs were applied in PICU patients, but none was validated for this population. NSTs did not include clinical, NS, laboratory, or dietary variables that were deemed relevant for the PICU population.

CONCLUSION

None of the available NSTs were found to be suitable for critically ill children, so a new NST should be developed for this population. AQ6.

Long-stay patients in pediatric intensive care units. Five-years, 2-points, cross-sectional study

Objectives:

To explore the changing patterns of long-stay patients (LSP) to improve the utilization of pediatric intensive care units (PICUs) resources.

Methods:

This is a 2-points cross-sectional study (5 years apart; 2014-2019) conducted among PICUs and SCICUs in Riyadh, Saudi Arabia. Children who have stayed in PICU for more than 21 days were included.

Results:

Out of the 11 units approached, 10 (90%) agreed to participate. The prevalence of LSP in all these hospitals decreased from 32% (48/150) in 2014 to 23.4% (35/149) in 2019. The length of stay ranged from 22 days to 13.5 years. The majority of LSP had a neuromuscular or cardiac disease and were admitted with respiratory compromise. Ventilator-associated pneumonia was the most prevalent complication (37.5%). The most commonly used resources were mechanical ventilation (93.8%), antibiotics (60.4%), and blood-products transfusions (35.4%). The most common reason for the extended stay was medical reasons (51.1%), followed by a lack of family resources (26.5%) or lack of referral to long-term care facilities (22.4%).

Conclusion:

A long-stay is associated with significant critical care bed occupancy, complications, and utilization of resources that could be otherwise utilized as surge capacity for critical care services. Decreasing occupancy in this multicenter study deserves further engagement of the healthcare leaders and families to maximize the utilization of resources.
