Risk factors for hospitalizations due to bacterial respiratory tract infections after tracheotomy

Pneumonia in Children With Complex Chronic Conditions With Tracheostomy: An Emerging Challenge

BACKGROUND

Despite respiratory infections being a leading cause of hospitalization in children with tracheostomy tubes, there are no published guidelines for their diagnosis and management. This study aims to outline the clinical, laboratory and microbiological aspects of pneumonia in these children, along with the antibiotics used and outcomes. Additionally, it seeks to determine pneumonia incidence and associated risk factors.

METHODS

We conducted a retrospective study using the medical records of tracheostomized children at La Paz University Hospital in Madrid from 2010 to 2021.

RESULTS

Thirty-three pneumonia cases were observed in 25 tracheostomized children. Pseudomonas aeruginosa was the predominant bacterium (52%), followed by Escherichia coli, Staphylococcus aureus and Serratia marcescens. The same microorganism isolated in the tracheal aspirate culture during pneumonia was previously isolated in 83% of cases that had a similar culture, with some growth obtained within 7-30 days prior. Multiplex respiratory PCR detected respiratory viruses in 73% of cases tested. Antibiotic treatment was administered in all cases except 1, mostly intravenously (81%), with piperacillin/tazobactam and meropenem being commonly used. Only 1 of the described episodes had a fatal outcome.

CONCLUSIONS

It is advisable to include coverage for P. aeruginosa, E. coli, S. aureus, and S. marcescens in the empirical antibiotic treatment for pneumonia in tracheostomized children, along with the microorganisms identified in tracheal cultures obtained within 7-30 days prior, if available. A positive PCR for respiratory viruses is often discovered in bacterial pneumonia in tracheostomized children.

Sim-Based Home Tracheostomy Care: A Mixed Methods Study on Outcomes and Parental Preparedness

OBJECTIVES

To assess effects of a Simulation-Based Discharge Education Program (SDP) on long-term caregiver-reported satisfaction and to compare clinical outcomes for children with new tracheostomies whose caregivers completed SDP versus controls.

METHODS

The study employed a mixed methods approach: (1) a qualitative analysis of feedback from caregivers who previously completed SDP, and (2) a quantitative retrospective case-control study comparing outcomes between children with new tracheostomies whose caregivers completed SDP versus controls, matched on discharge disposition and age. The primary outcome was emergency department visits for tracheostomy-related issues within 1 year of discharge.

RESULTS

Feedback from 18 interviews was coded into 5 themes: knowledge acquisition, active learning, comfort and preparedness, home application of skills, and overall assessment. Caregivers of 27 children (median age 26 months [interquartile range (IQR) 5.5 months-11 years]) underwent SDP training. Clinical outcomes of these children were compared with 27 matched children in the non-SDP group (median age 16 months [IQR 3.5 months-10 years]). There was no significant difference in ED visits for tracheostomy-related complications within 1 year of discharge between the SDP group and non-SDP group (2 [IQR 0-2] vs 1 [IQR 0-2], P = .2).

CONCLUSIONS

Caregivers reported overwhelmingly positive experiences with SDP that persisted even 4 years after training. Caregiver participation in SDP did not yield a significant difference in ED visits within 1 year of discharge for tracheostomy-related complications compared with control counterparts. Future steps will identify more effective methods for comparing and analyzing clinical outcomes to further validate impacts of simulation-based programs.

Microbiological patterns of bacterial infections in tracheostomized children: Reducing uncertainty in continuous care

BACKGROUND AND OBJECTIVES

Respiratory infections are the most frequent cause of hospitalization in tracheostomized children. However, there is a lack of publications to guide their management. The primary objective was to describe the microbiological isolates and their antibiotic susceptibilities of bacterial respiratory infections in a population of tracheostomized children.

METHODS

Retrospective follow-up study of children with tracheostomy seen at a tertiary hospital. Respiratory infection episodes in patients under 18 years of age who had a tracheostomy and bacterial isolation with a count ≥104 Colony Forming Units/mL in tracheal aspirate were included.

RESULTS

The study analyzed 328 respiratory infection episodes: 164 tracheobronchitis (50%), 112 nonspecific respiratory episodes (34.1%), and 52 pneumonias (15.9%). The most commonly isolated microorganisms were Pseudomonas aeruginosa, Serratia marcescens, and Staphylococcus aureus. The antibiotics that exhibited the highest effectiveness were meropenem (92%), imipenem (87%), and levofloxacin (86%). When hospitalization exceeded 7 days, there was a higher chance of isolating Escherichia coli and Klebsiella pneumoniae (p < 0.001 and p = 0.001, respectively), as well as an increased rate of multidrug resistance (27% vs. 7%, p = 0.035). In 75.3% of cases, the microorganism had been previously isolated in a sample taken 7-30 days before the current one, with a higher frequency observed in the case of P. aeruginosa (95.2%) compared to other microorganisms (65.3%, p < 0.001).

CONCLUSIONS

Meropenem, imipenem, and levofloxacin provided the most effective coverage for these infections. The risk of multidrug resistance increased with longer hospital stays, especially for E. coli and K. pneumoniae. Recent isolation of P. aeruginosa may justify empirical coverage.

Respiratory culture organism isolation and test characteristics in children with tracheostomies with and without acute respiratory infection

BACKGROUND

Among children with tracheostomies, little is known about how respiratory culture results differ between states with and without acute respiratory infections (ARI), or the overall test performance of respiratory cultures.

OBJECTIVE

To determine the association of respiratory culture organism isolation with diagnosis of ARI in children with tracheostomies, and assess test characteristics of respiratory cultures in the diagnosis of bacterial ARI (bARI).

METHODS

This single-center, retrospective cohort study included respiratory cultures of children with tracheostomies obtained between 2010 and 2018. The primary predictor was ARI diagnosis code at the time of culture; the primary outcomes were respiratory culture organism isolation and species identified. Generalized estimating equations were used to assess for association between ARI diagnosis and isolation of any organism while controlling for potential confounders and accounting for within-patient clustering. A multinomial logistic regression equation assessed for association with specific species. Test characteristics were calculated using bARI diagnosis as the reference standard.

RESULTS

Among 3578 respiratory cultures from 533 children (median 4 cultures/child, interquartile range (IQR): 1-9), 25.9% were obtained during ARI and 17.2% had ≥1 organism. Children with ARI diagnosis had higher odds of organism identification (adjusted odds ratio 1.29, 95%  confidence interval [CI] 1.16-1.44). When controlling for covariates, ARI was associated with isolation of Haemophilus influenzae, Moraxella catarrhalis, Streptococcus pneumoniae, and Streptococcus pyogenes. Test characteristics revealed a 24.3% sensitivity, 85.2% specificity, 36.5% positive predictive value, and 76.3% negative predictive value in screening for bARI.

CONCLUSION

The utility of respiratory culture testing to screen for, diagnose, and direct treatment of ARI in children with tracheostomies is limited.

Emergency Department Visits and Hospitalizations After Pediatric Tracheostomy

OBJECTIVE

To determine factors associated with frequent emergency department (ED) visits and hospitalizations after pediatric tracheostomy.

METHODS

A prospective cohort of children (<18 years) with a tracheostomy placed at a tertiary children's hospital between 2015 and 2019 were followed for 24 months after index discharge. ED visits and hospitalizations were recorded to identify risk factors for frequent utilization (≥4 visits).

RESULTS

A total of 239 children required 1285 total visits to the ED or hospital after index discharge with 112 children (47%) having ≥4 visits. Respiratory-related illness was the most common reason (N = 699, 54%) followed by gastrostomy tube issues (N = 119, 9.3%). Frequent utilization was associated with Black race (OR: 2.01, 95% CI: 1.18-3.70, p = 0.01), mechanical ventilation (OR: 2.74, 95% CI: 1.35-5.59, p = 0.006), and Spanish language (OR: 3.86, 95% CI: 1.47-10.11, p = 0.006) on regression modeling. There were no predictors of visits for tracheostomy-related complications, which accounted for 4.8% of all encounters. A sub-analysis showed that Hispanic ethnicity and gestational age predicted visits for respiratory failure.

CONCLUSION

Frequent ED visits or hospitalizations are required for 47% of children in the first 2 years after tracheostomy placement. Ventilatory support, Black race, and Spanish language increase the likelihood of high utilization. Although tracheostomy-related visits are uncommon, strategies to anticipate and decrease respiratory-related admissions may have the most impact.

Prevention of Severe Respiratory Tract Infection and Prognosis in Neurosurgical Patients with Severe Tracheotomy Based on 5E Rehabilitation Nursing Model

Background

Continuous nursing based on 5E rehabilitation mode can improve the physiology and psychology of patients to some extent. The purpose of this study was to explore the effect of continuous nursing of 5E rehabilitation mode on the prevention and prognosis of severe respiratory tract infection in patients with severe tracheotomy in neurosurgery.

Objective

To explore the effect of 5E rehabilitation nursing model on the prevention of severe respiratory tract infection and prognosis in patients with severe tracheotomy in neurosurgery.

Methods

The starting and ending time of this study is from February 2019 to July 2021. In this paper, 60 patients with severe tracheotomy were divided into the control group and research group according to random number table method. The former group received routine nursing, and the latter group received rehabilitation nursing model based on 5E. The patients' satisfaction, oxygenation index, partial pressure of carbon dioxide, partial pressure of oxygen, SAS, SDS score, incidence of severe respiratory tract infection, and quality of life scores were compared.

Results

The nursing satisfaction of the research group was higher than that of the control group (P < 0.05). 24 hours after weaning, the oxygenation index and partial pressure of oxygen in the research group were higher than those in the control group, while the partial pressure of carbon dioxide in the research group was lower than that in the control group (P < 0.05). After nursing, the scores of self-rating anxiety scale and self-rating depression scale in the research group were lower than those in the control group, and the difference was statistically significant (P < 0.05). The incidence of severe respiratory tract infection in the research group was significantly lower than that in the control group (P < 0.05). After nursing, the scores of physiological function, psychological function, social function, and health self-cognition in the research group were lower than those in the control group (P < 0.05).

Conclusion

The nursing program of neurosurgical patients with severe tracheotomy based on 5E rehabilitation model can effectively enhance patients' nursing satisfaction, activities of daily living, anxiety, and depression and promote the prognosis.

Home mechanical ventilation for children with severe neurological impairment: Parents' perspectives on clinician counselling

AIM

To retrospectively explore the perspectives of parents of children with severe neurological impairment (SNI), such as those with severe cerebral palsy, epilepsy syndromes, and structural brain differences, on clinician counseling regarding home mechanical ventilation (HMV).

METHOD

Inductive thematic analysis was performed on data from telephone interviews with parents who chose for and against HMV for their child with SNI at three academic children's hospitals across the USA.

RESULTS

Twenty-six parents/legal guardians of 24 children were interviewed. Fourteen children had static encephalopathy, 11 received HMV, and 20 were alive at the time of parent interviews. Themes included how HMV related to the child's prognosis, risk of death, and integration with goals of care. Although clinicians voiced uncertainty about how HMV would impact their child, parents felt this was coupled with prescriptive/intimidating examples about the child's end of life and judgments about the child's quality of life.

INTERPRETATION

While prognositc uncertainty exists, this study suggests that parents of children with SNI seek clinician counseling about HMV that considers their goals of care and views on their child's quality of life.

Diagnosis, management, and outcomes of pediatric tracheostomy-associated infections: A scoping review

BACKGROUND

Children with tracheostomy are frequently admitted to the hospital for tracheostomy-associated respiratory infections (TRAINs). However, there remains a paucity of evidence to direct the diagnosis, treatment, and prevention of TRAINs. An important first step to addressing this knowledge gap is to synthesize existing data regarding TRAINs to inform current practice and facilitate innovation.

DATA SOURCES

We searched PubMed, Embase, Cochrane Library, CINAHL, and Web of Science from inception to October 2020. Original research articles and published abstracts including children and young adults 0-21 years of age with tracheostomy were included. Included studies assessed the clinical definitions of and risk factors for TRAINs, microbiologic epidemiology and colonization of tracheostomies, and treatment and outcomes of TRAINs.

DATA SYNTHESIS

Out of 5755 studies identified in the search, 78 full-text studies were included in the final review. A substantial number of studies focused on the detection of specific pathogens in respiratory cultures including Pseudomonas aeruginosa. Several different definitions of TRAIN including clinical, microbiologic, and laboratory testing results were utilized; however, no uniform set of criteria were identified. The few studies focused on treatment and prevention of TRAIN emphasized the role of empiric antimicrobial therapy and the use of inhaled antibiotics.

CONCLUSIONS

Despite a growing number of research articles studying TRAINs, there is a paucity of prospective interventional trials to guide the diagnosis, treatment, and prevention of respiratory disease in this vulnerable population. Future research should include studies of interventions designed to improve short- and long-term respiratory-related outcomes of children with tracheostomy.

Long-term Outcomes of Pediatric Tracheostomy Home Care in a Limited Resource Setting of Professional Home Nurse

Long-term outcomes of pediatric patients with a tracheostomy in developing countries where professional home nurse is not accessible has rarely been reported. We, therefore, investigated the prevalence and associating factors of long-term outcomes in these children. Retrospective chart review was conducted in 85 tracheostomized children who were discharged to home during January 2012 to December 2020. Tracheostomy home care was provided by caregivers who completed the tracheostomy home care program. Prevalence of unplanned readmission with acute respiratory problems within 30 days after the first hospital discharge was 17.6%. Lower respiratory tract infection (LRTI) after hospital discharge was found in 72.9% (median frequency of 1.0 episode/case/year). Among 80 children who had surveillance airway endoscopy, 46.3% demonstrated late tracheostomy-related airway complications. Independent factor associated with late tracheostomy-related airway complications was a follow-up period longer than 1 year. Decannulation success was found in 21.2%. Most of them had tracheostomy for their upper airway anomalies. The mortality rate was 7%. Most of them died from their underlying diseases. In conclusion, pediatric tracheostomy home care undertaken by caregivers is feasible in developing countries where home nurse is not available. The prevalence of unplanned readmission with acute respiratory problems within 30 days after hospital discharge and late tracheostomy-related airway complications were comparable with those reported in developed countries. However, we still had a high prevalence of post-tracheostomy LRTI which was a challenging problem that needed to be investigated and resolved.

Continuous humidification enhances postoperative recovery in laryngeal cancer patients undergoing tracheotomy

OBJECTIVE

To investigate the effects of perioperative continuous humidification on patients with laryngeal cancer undergoing tracheotomy.

METHODS

Eighty patients with laryngeal cancer underwent tracheotomy in our hospital were selected as the subjects and divided into the observation group and the control group according to random table method. Patients in the control group were given routine tracheotomy care, including regular open endotracheal suction, tracheotomy nursing, oral care, dietary intervention, etc., while those in the observation group were given continuous airway humidification on the basis of the control group. The differences in sputum pH, viscosity, comfort, cough frequency, and respiratory ventilation were compared between the two groups at three postoperative time points. The incidence of complications such as pulmonary infection, bloody sputum and sputum crust, and the improvement of clinical symptoms were compared between the two groups.

RESULTS

The sputum pH of patients in the observation group was higher than that in the control group at the 4th and 7th postoperative days (P<0.001). The observation group showed significantly lower percentage of grade 3 viscous sputum and higher comfort scores than the control group at the 7th postoperative day (P=0.020, P<0.001). The observation group showed lower cough frequency and higher airway patency than the control group at the 4th and 7th postoperative days (P<0.001, P<0.001, P<0.001, P=0.007).

CONCLUSION

Perioperative continuous airway humidification in patients with laryngeal cancer undergoing tracheotomy could reduce sputum consistency and cough frequency, improve comfort and respiratory patency of patients, and has positive significance in accelerating their postoperative rehabilitation.

Variation in Bacterial Respiratory Culture Results in Children With Neurologic Impairment

OBJECTIVES

To examine bacterial respiratory cultures in children with neurologic impairment (NI) (eg, cerebral palsy), both with and without tracheostomies, who were hospitalized with acute respiratory infections (ARIs) (eg, pneumonia) and to compare culture results across hospitals and age groups.

METHODS

This multicenter retrospective cohort study included ARI hospitalizations for children aged 1 to 18 years with NI between 2007 and 2012 who had a bacterial respiratory culture obtained within 2 days of admission. Data from 5 children's hospitals in the Pediatric Health Information System Plus database were used. Organisms consistent with oral flora and nonspeciated organisms were omitted from analysis. The prevalence of positive respiratory culture results and the prevalence of organisms identified were compared across hospitals and age groups and in subanalyses of children with and without tracheostomies by using generalized estimating equations to account for within-patient clustering.

RESULTS

Of 4900 hospitalizations, 693 from 485 children had bacterial respiratory cultures obtained. Of these, 54.5% had positive results, although this varied across hospitals (range 18.6%-83.2%; P < .001). Pseudomonas aeruginosa and Staphylococcus aureus were the most commonly identified organisms across hospitals and age groups and in patients with and without tracheostomies. Large variation in growth prevalence was identified across hospitals but not age groups.

CONCLUSIONS

The bacteriology of ARI in hospitalized children with NI differs from that of otherwise healthy children. Significant variation in prevalence of positive bacterial respiratory culture results and organism growth were observed across hospitals, which may be secondary to local environmental factors and microbiology reporting practices.

Melanocytes determine angiogenesis gene expression across human tissues

Several angiogenesis-dependent diseases, including age-related macular degeneration and infantile hemangioma, display differential prevalence among Black, as compared to White individuals. Although socioeconomic status and genetic architecture have been suggested as explaining these differences, we have recently shown that pigment production per se might be involved. For example, we have shown that the extracellular protein fibromodulin is a pro-angiogenic factor highly secreted by melanocytes in White but not Black individuals. Still, additional pigment-dependent angiogenic factors and their molecular mechanisms remain to be identified. Understanding the contribution of pigmentation to angiogenesis in health and disease is essential for precision medicine of angiogenesis-dependent diseases with racial disparity. Toward that goal, we compared the transcriptomes of Black and White individuals in three tissues with angiogenic activity, namely artery, whole blood, and skin. We identified several differentially expressed angiogenesis pathways, including artery morphogenesis, regulation of endothelial cell chemotaxis, and cellular response to vascular endothelial growth factor stimulus. We then demonstrated that the expression of key genes in these pathways is directly modulated by the degree of pigmentation. We further identified the precise pigment production pathway controlling the expression of these genes, namely melanocortin 1 receptor (MC1R) signaling. These results demonstrate pigment-mediated regulation of angiogenesis-related pathways and their driver genes across human tissues.

Children dependent on respiratory support: A 10-year review from one pediatric postacute care hospital

OBJECTIVE

Pediatric postacute care hospitals (PACH) provide long-term care for children with medical complexity including children dependent on respiratory support. Descriptions of PACH respiratory care populations and outcomes, however, remain under-reported. Our aim was to describe demographics, respiratory outcome, and longitudinal trend of children with respiratory support admitted to a single PACH in the United States.

METHODS

Using electronic records from 2009 to 2018, data were examined for all children dependent on respiratory support. Children were identified for inclusion using respiratory level of care classifications (type of support) as outlined in hospital policy. Outcome was defined as change in level from first admission to final discharge. Number of admissions by level and year during the study timeframe were analyzed.

RESULTS

There were 1423 admissions for 767 children requiring respiratory support during the study timeframe. Children with higher respiratory classification level (eg, mechanical ventilation) at initial admission had more admissions to PACH (P < .001) and longer length of stays (P < .001). From first admission to final discharge, there was a significant change (reduction) in respiratory level (z = -4.588, P < .001). An increase in the overall number of admissions for children with respiratory support during the study timeframe was noted, with the largest increase for children requiring the highest level of support.

CONCLUSION

There has been a consistent increase in the number of children requiring respiratory support at admission to PACH. Reduction in respiratory support with postacute care occurs but children admitted with a higher level of support stay longer and experience multiple admissions.

Readmission drivers for children with medical complexity: Home nursing shortages cause health crises

OBJECTIVE

Children with medical technology dependence (MTD) are frequently readmitted to the hospital. However, due to their medical fragility, it is often difficult to untangle the root causes for readmissions to identify the most effective preventive approaches. We sought to explore environmental and family factors driving hospital readmissions for children with MTD.

DESIGN

Semi-structured, in-person interviews were conducted with state-wide care coordinators for children with MTD in Illinois with at least 1 year of experience. Interview topics related to children with MTD transitioning from hospital-to-home, essential supports for living in the community, and factors which influenced and prevented hospital readmission. The interview guide served as an initial codebook which was iteratively modified as themes emerged.

RESULTS

Fifteen care coordinators with on average 6.6 years of experience were interviewed. They described that lack of home nursing was one of the primary drivers of readmissions due to parental exhaustion and lack of medical expertize in the home. Unavoidable medical admissions, a lack of a plan for emergencies, and home environmental factors also contributed to readmissions.

CONCLUSION

Hospital readmission is an expected occurrence for children with MTD, yet still may be substantially reduced through consistent, quality home health nursing to bolster family capacity and allow for respite from constant caregiving. Improved incentives for the home health workforce to increase manpower would be ultimately offset by reduced hospitalizations for children with MTD. Additionally, more research is needed to understand which home nursing structures and skills optimally support families in the reality of manpower scarcity.

Indications and outcomes of paediatric tracheotomy: a descriptive study using a Japanese claims database

OBJECTIVE

To examine the incidence of and indications for paediatric tracheotomy to clarify the disease burden relevant to tracheotomy in a population-based context.

DESIGN

A descriptive analysis of a retrospective cohort.

SETTING

This study utilised a nationwide claims database in Japan constructed by JMDC (Tokyo, Japan). The database includes claims data for approximately 3.75 million insured persons (approximately 3.1% of the population of Japan) comprising mainly company employees and their family members.

PARTICIPANTS

We identified children registered to have undergone tracheotomy from 2005 to 2017 among about 1.2 million children aged 0-15 years.

MAIN OUTCOME MEASURES

The characteristics of the study population, and indications for tracheotomy, duration of hospital stay, duration of mechanical ventilation, duration of tracheotomy dependence, complications related to tracheotomy and death were assessed. When there were multiple indications, classification for a child into multiple groups was allowed.

RESULTS

The study included 215 children (120 males, 56%). The median age at tracheotomy was 0.8 years. The most common age at tracheotomy was less than 12 months (n=127, 59.1%). The most common indications for tracheotomy were chronic lung disease (n=79, 36.7%), followed by neuromuscular disease (n=77, 35.8%), cardiovascular disease (n=53, 24.3%), upper airway obstruction (n=43, 20%), premature birth and related conditions (n=34, 15.8%), trauma (n=16, 7.4%), prolonged ventilation due to other causes (n=12, 5.6%) and malignancy (n=9, 4.2%). The median duration of tracheotomy dependence was 17.2 months. During the follow-up period, decannulation was achieved in 84 children (39.1%), and the median time from tracheotomy to decannulation was 12.0 months.

CONCLUSIONS

Most paediatric tracheotomies were performed due to chronic underlying diseases, and the mean duration of tracheotomy dependence was nearly 1-½ years. The long-term duration of tracheotomy dependence might have some impacts on patients' physical and mental development and the quality of life.

Development of Chronic Pseudomonas aeruginosa-Positive Respiratory Cultures in Children with Tracheostomy

BACKGROUND

Up to 90% of children develop Pseudomonas aeruginosa (Pa)-positive respiratory cultures after tracheotomy.

OBJECTIVE

To identify the factors associated with chronic Pa-positive respiratory cultures in the first 2 years after tracheotomy.

METHODS

We conducted a retrospective cohort study of 210 children ≤ 18 years old who underwent tracheotomy at a single freestanding children's hospital that had two or more years of respiratory cultures post-tracheotomy available for analysis. We conducted multivariable logistic regression to test the association between demographic and clinical factors to our primary outcome of chronic Pa infection, defined as > 75% of respiratory cultures positive for Pa in the first 2 years after tracheotomy.

RESULTS

Of the primarily male (61%), Hispanic (68%), and publicly insured (88%) cohort, 18% (n = 37) developed chronic Pa-positive respiratory cultures in the first 2 years. On multivariable logistic regression, pre-tracheotomy Pa-positive respiratory culture (aOR 11.3; 95% CI 4-1.5) and discharge on beta agonist (aOR 6.3; 95% CI 1.1-36.8) were independently associated with chronic Pa-positive respiratory cultures, while discharge on chronic mechanical ventilation was associated with decreased odds (aOR 0.3; 95% CI 0.1-0.7). On sensitivity analysis examining those without a pre-tracheotomy Pa-positive respiratory culture, discharge on MV continued to be associated with decreased odds of chronic Pa (aOR 0.1; 95% CI 0.02-0.4) and three other variables (male gender, chronic lung disease, and discharge on inhaled corticosteroids) were associated with increased odds of chronic Pa.

CONCLUSION

Because pre-tracheotomy Pa growth on respiratory culture is associated with post-tracheotomy chronic Pa-positive respiratory cultures, future research should examine pre-tracheotomy Pa eradication or suppression protocols.

Pediatric Pulmonology year in review 2018: Asthma, physiology/pulmonary function testing, and respiratory infections

Pediatric Pulmonology publishes original research, reviews, and case reports related to a wide range of children's respiratory disorders. In our "Year in Review" series, we summarize publications in our major topic areas from 2018, in the context of selected literature in these areas from other journals relevant to our discipline. This review covers selected articles on asthma, physiology/lung function testing, and respiratory infections.

Early Use of Anti-influenza Medications in Hospitalized Children With Tracheostomy

BACKGROUND

Early administration of anti-influenza medications is recommended for all children hospitalized with influenza. We investigated whether early use of anti-influenza medications is associated with improved outcomes in children with tracheostomy hospitalized with influenza.

METHODS

We performed a multicenter retrospective cohort study through the Pediatric Health Information System database for patients aged 30 days to 19 years who were discharged between October 1, 2007, and September 30, 2015 with diagnostic codes for both influenza and tracheostomy. Our primary predictor was receipt of anti-influenza medications on hospital day 0 or 1. We used propensity score matching to adjust for confounding by indication. Primary outcomes were length of stay (LOS) and 30-day all-cause revisit rate (emergency department visit or hospital admission).

RESULTS

Of 1436 discharges screened, 899 met inclusion criteria. The median admission age was 5 years (interquartile range: 2-10). The majority had multiple complex chronic conditions (median 3; interquartile range: 3-4) and technology dependence, such as gastrostomy tube (73.6%). After matching 772 unique admissions by propensity score, LOS was shorter for the cohort receiving early anti-influenza medications (6.4 vs 7.5 days; P = .01) without increase in revisit rate (27.5% vs 24.1%; P = .28). More than 80% in both cohorts received empirical antibiotics, and the duration of antibiotic therapy was similar (5.0 vs 5.6 days; P = .11).

CONCLUSIONS

Early use of anti-influenza medications in children with tracheostomy hospitalized with influenza is associated with shorter LOS, but these children continue to receive antibiotics despite identification and treatment of their viral infections.

Encounters From Device Complications Among Children With Medical Complexity

OBJECTIVES

Children with medical complexity (CMC) are commonly assisted by medical devices to support essential body functions, although complications may lead to preventable emergency department (ED) and hospital use. Our objective was to identify predictors of device-complicated ED visits and hospitalizations.

METHODS

This single-center retrospective cohort study included patients referred to a Pediatric Complex Care Program between April 1, 2014, and April 30, 2016, assisted by at least 1 medical device. Hospitalizations and ED visits in the year before enrollment were rated for likelihood for being due to device complications. Interrater reliability among 3 independent reviewers was assessed. Bivariate followed by multivariate logistic regression clustered by patient helped us identify associations between demographic, clinical, and device characteristics associated with device-complicated ED or hospital encounters.

RESULTS

Interrater reliability was high (κ = 0.92). Among 98 CMC, device-complicated encounters represented 17% of 258 hospitalizations and 31% of 228 ED visits. Complications of 3 devices (central venous catheters, enteral tubes, and tracheostomy tubes) accounted for 13% of overall hospitalizations and 28% of overall ED visits. Central venous catheter presence (adjusted odds ratio [aOR] 3.2 [95% confidence interval (CI) 1.1-9.5]) was associated with device-complicated ED visits. Gastrojejunostomy/jejunostomy tube presence (aOR 3.3 [95% CI 1.5-7.5]) or tracheostomies with (aOR 8.1 [95% CI 2.3-28.5]) or without (aOR 4.5 [95% CI 1.7-7.5]) ventilator use was associated with device-complicated hospitalizations. Clinical variables were poor predictors of device-complicated encounters.

CONCLUSIONS

Device-complicated ED visits and hospitalizations comprised a substantial proportion of total hospital and ED use. Developing interventions to prevent device complications may be a promising strategy to reduce overall CMC use.
