Differences upon admission and in hospital course of children hospitalized with community-acquired pneumonia with or without radiologically-confirmed pneumonia: a retrospective cohort study

Study Protocol for Preventing Early-Onset Pneumonia in Young Children Through Maternal Immunisation: A Multi-Centre Randomised Controlled Trial (PneuMatters)

Background: Preventing and/or reducing acute lower respiratory infections (ALRIs) in young children will lead to substantial short and long-term clinical benefits. While immunisation with pneumococcal conjugate vaccines (PCV) reduces paediatric ALRIs, its efficacy for reducing infant ALRIs following maternal immunisation has not been studied. Compared to other PCVs, the 10-valent pneumococcal-Haemophilus influenzae Protein D conjugate vaccine (PHiD-CV) is unique as it includes target antigens from two common lower airway pathogens, pneumococcal capsular polysaccharides and protein D, which is a conserved H. influenzae outer membrane lipoprotein. Aims: The primary aim of this randomised controlled trial (RCT) is to determine whether vaccinating pregnant women with PHiD-CV (compared to controls) reduces ALRIs in their infants' first year of life. Our secondary aims are to evaluate the impact of maternal PHiD-CV vaccination on different ALRI definitions and, in a subgroup, the infants' nasopharyngeal carriage of pneumococci and H. influenzae, and their immune responses to pneumococcal vaccine type serotypes and protein D. Methods: We are undertaking a parallel, multicentre, superiority RCT (1:1 allocation) at four sites across two countries (Australia, Malaysia). Healthy pregnant Australian First Nation or Malaysian women aged 17-40 years with singleton pregnancies between 27⁺⁶ and 34⁺⁶ weeks gestation are randomly assigned to receive either a single dose of PHiD-CV or usual care. Treatment allocation is concealed. Study outcome assessors are blinded to treatment arms. Our primary outcome is the rate of medically attended ALRIs by 12-months of age. Blood and nasopharyngeal swabs are collected from infants at birth, and at ages 6- and 12-months (in a subset). Our planned sample size (n = 292) provides 88% power (includes 10% anticipated loss to follow-up). Discussion: Results from this RCT potentially leads to prevention of early and recurrent ALRIs and thus preservation of lung health during the infant's vulnerable period when lung growth is maximum. The multicentre nature of our study increases the generalisability of its future findings and is complemented by assessing the microbiological and immunological outcomes in a subset of infants.

Lung ultrasound in diagnosing pneumonia in childhood: a systematic review and meta-analysis

PURPOSE

Pneumonia is the third leading cause of death in children under 5 years of age worldwide. In pediatrics, both the accuracy and safety of diagnostic tools are important. Lung ultrasound (LUS) could be a safe diagnostic tool for this reason. We searched in the literature for diagnostic studies about LUS to predict pneumonia in pediatric patients using systematic review and meta-analysis.

METHODS

The Medline, CINAHL, Cochrane Library, Embase, SPORTDiscus, ScienceDirect, and Web of Science databases from inception to September 2017 were searched. All studies that evaluated the diagnostic accuracy of LUS in determining the presence of pneumonia in patients under 18 years of age were included.

RESULTS

1042 articles were found by systematic search. 76 articles were assessed for eligibility. Seventeen studies were included in the systematic review. We included 2612 pooled cases. The age of the pooled sample population ranged from 0 to about 21 years old. Summary sensitivity, specificity, and AUC were 0.94 (IQR: 0.89-0.97), 0.93 (IQR: 0.86-0.98), and 0.98 (IQR: 0.94-0.99), respectively. No agreement on reference standard was detected: nine studies used chest X-rays, while four studies considered the clinical diagnosis. Only one study used computed tomography.

CONCLUSIONS

LUS seems to be a promise tool for diagnosing pneumonia in children. However, the high heterogeneity found across the individual studies, and the absence of a reliable reference standard, make the finding questionable. More methodologically rigorous studies are needed.

Dyspnea in Children as a Symptom of Acute Respiratory Tract Infections and Antibiotic Prescribing

BACKGROUND:

Dyspnea is an unpleasant feeling of breathing difficulty, shortness of breath and inability to satisfy the hunger for air. The role of family physicians is to be prepared to recognise dyspnea as a symptom of acute respiratory infections (ARI), to perform triage and managing of children with acute dyspnea and make continuous education of parents. In the treatment of acute dyspnea more important is to treat dyspnea as a symptom than the prescribing of antibiotics (AB). Nowadays, even more often large amount of children, because of the noncompliance in the treatment and the pressure from the parents, unnecessary is hospitalised and frequently used antibiotics: According to the guidelines, a small percentage of children with ARI should be treated with AB. The rate of antibiotic prescription should be around 15-20% and lower.

AIM:

To assess doctor’s AB prescriptions in Primary care practices in Macedonia, for ARI and dyspnea in children we use the data from a National project about antibiotic prescribing for acute respiratory tract infections, which has been run in 2014 November as a part of E - quality program.

METHODS:

Eighty-six general practitioners from Macedonia have taken participation in it. The group of 3026 children, from 0-5 years of age, with symptoms of dyspnea, was analysed. We have found a rate of 54.6% antibiotic prescriptions (AB). From 3026 children with dyspnea, AB got 1519 children, 852 of which were prescribed by a specialist.

RESULTS:

The children were mostly diagnosed with upper ARI, in 57.7%. The most used AB is amoxicillin + clavulonic acid. We concluded that there was an increased and inappropriate prescribing of antibiotics in children with ARI, presented with dyspnea in Macedonia.

CONCLUSION:

Perceptions and the parent’s attitudes do not correlate with the severity of clinical picture of the disease in children and lack of use Evidence-based medicine (EBM), insecurity, fear, loss of patients effect on antibiotic prescribing of the doctors.

A Multisite Intervention for Pediatric Community-acquired Pneumonia in Community Settings

OBJECTIVES

The majority of children with community-acquired pneumonia (CAP) are primarily evaluated in community hospital emergency departments (EDs); however, studies on the management of pediatric CAP have largely targeted care provided in freestanding children's hospital EDs or inpatient settings. The objectives of this study were to examine whether implementation of a CAP pathway within three community hospital EDs and inpatient units improved process measures related to appropriate laboratory testing and antibiotic prescribing and to compare performance on these measures between the community hospitals and a freestanding children's hospital.

METHODS

Through a multidisciplinary approach (including general emergency medicine [EM] providers, pediatric fellowship-trained EM providers, and pediatric hospitalists), a CAP pathway was designed and implemented at three community hospitals in January and February 2016. Diagnostic and therapeutic process measures were collected using administrative data and medical record abstraction 1 year pre- and postintervention. Chi-square statistics and statistical process control P-charts were used to examine adherence to these process measures.

RESULTS

Across the community hospitals, 544 patients preintervention and 321 patients postintervention met inclusion criteria, with 290 children's hospital patients meeting criteria in the postintervention period. Adherence to process measures increased postintervention for appropriate laboratory testing, narrow-spectrum antibiotic stewardship and macrolide stewardship by 10.8% (95% confidence interval [CI] = 4.7% to 16.9%), 8.3% (95% CI = 21.5% to 15.2%), and 3.1% (95% CI = -4.3% to 10.4%), respectively. Statistical process control P-charts demonstrated special cause variation immediately after implementation of the intervention in regards to appropriate laboratory testing.

CONCLUSION

Implementation of a CAP pathway through a multisite community hospital intervention improved adherence to evidence-based recommendations for laboratory testing and antibiotic stewardship. Similar interventions may improve the quality of care for children with CAP on a population level, as community hospitals are where these patients are seen most frequently.
