Predicting severe pneumonia in the emergency department: a global study of the Pediatric Emergency Research Networks (PERN)-study protocol

Cost of Pediatric Pneumonia Episodes With or Without Chest Radiography

BACKGROUND AND OBJECTIVES

Despite its routine use, it is unclear whether chest radiograph (CXR) is a cost-effective strategy in the workup of community-acquired pneumonia (CAP) in the pediatric emergency department (ED). We sought to assess the costs of CAP episodes with and without CXR among children discharged from the ED.

METHODS

This was a retrospective cohort study within the Healthcare Cost and Utilization Project State ED and Inpatient Databases of children aged 3 months to 18 years with CAP discharged from any EDs in 8 states from 2014 to 2019. We evaluated total 28-day costs after ED discharge, including the index visit and subsequent care. Mixed-effects linear regression models adjusted for patient-level variables and illness severity were performed to evaluate the association between CXR and costs.

RESULTS

We evaluated 225c781 children with CAP, and 86.2% had CXR at the index ED visit. Median costs of the 28-day episodes, index ED visits, and subsequent visits were $314 (interquartile range [IQR] 208-497), $288 (IQR 195-433), and $255 (IQR 133-637), respectively. There was a $33 (95% confidence interval [CI] 22-44) savings over 28-days per patient for those who received a CXR compared with no CXR after adjusting for patient-level variables and illness severity. Costs during subsequent visits ($26 savings, 95% CI 16-36) accounted for the majority of the savings as compared with the index ED visit ($6, 95% CI 3-10).

CONCLUSIONS

Performance of CXR for CAP diagnosis is associated with lower costs when considering the downstream provision of care among patients who require subsequent health care after initial ED discharge.

Association of Chest Radiography With Outcomes in Pediatric Pneumonia: A Population-Based Study

OBJECTIVE

Chest radiograph (CXR) is often performed for the evaluation of community-acquired pneumonia (CAP) in the ED setting. We sought to evaluate the association of undergoing CXR with 7-day hospitalization after emergency department (ED) discharge among patients with CAP.

METHODS

This was a retrospective cohort study including children 3 months to 17 years discharged from any ED within 8 states from 2014 to 2019. We evaluated the association of CXR performance with 7-day hospitalization at both the patient and ED levels using mixed-effects logistic regression models accounting for markers of illness severity. Secondary outcomes included 7-day ED revisits and 7-day hospitalization with severe CAP.

RESULTS

Among 206 694 children with CAP, rates of 7-day ED revisit, hospitalization, and severe CAP were 8.9%, 1.6%, and 0.4%, respectively. After adjusting for illness severity, CXR was associated with fewer 7-day hospitalizations (1.6% vs. 1.7%, adjusted odds ratio: [aOR] 0.82, 95% confidence interval [CI]: 0.73-0.92). CXR performance varied somewhat between EDs (median 91.5%, IQR: 85.3%-95.0%). EDs in the highest quartile had fewer 7-day hospitalizations (1.4% vs 1.9%, aOR: 0.78, 95% CI: 0.65-0.94), ED revisits (8.5% vs 9.4%, aOR: 0.88, 95% CI: 0.80-0.96) and hospitalizations for severe CAP (0.3% vs. 0.5%, aOR: 0.70, 95% CI: 0.51-0.97) as compared to EDs with the lowest quartile of CXR utilization.

CONCLUSIONS

Among children discharged from the ED with CAP, performance of CXR was associated with a small but significant reduction in hospitalization within 7 days. CXR may be helpful in the prognostic evaluation of children with CAP discharged from the ED.

Factors associated with severe childhood community-acquired pneumonia: a retrospective study from two hospitals

Background

Community-acquired pneumonia (CAP) is the leading cause of death in children globally. Indonesia is ranked 1st in South East Asia with the highest burden of pneumonia. Identification of risk factors is necessary for early intervention and better management. This study intended to describe CAP’s clinical signs and laboratory findings and explore the risk factors of severe CAP among children in Indonesia.

Methods

This was a retrospective study of childhood hospitalizations in Siloam General Hospitals and Siloam Hospitals Lippo Village from December 2015 to December 2019. Demographic data, clinical signs, and laboratory findings were collected and processed using IBM SPSS 26.0.

Results

This study included 217 participants with 66 (30.4%) severe pneumonia cases. Multivariate analysis shows that fever that lasts more than 7 days (ORadj = 4.95; 95%CI 1.61–15.21, Padj = 0.005) and increase in respiratory rate (ORadj = 1.05, 95%CI 1.01–1.08, Padj = 0.009) are two predictors of severe pneumonia. Meanwhile, a normal hematocrit level (ORadj = 0.9; 95%CI 0.83–0.98, Padj = 0.011) and children with normal BMI (ORadj = 0.7; 95%CI 0.57–0.84, Padj < 0.001) are significant independent predictors of severe pneumonia. The Hosmer-Lemeshow test shows that this model is a good fit with a P-value of 0.281. The AUC for this model is 0.819 (95%CI = 0.746–0.891, P-value < 0.001) which shows that this model has good discrimination.

Conclusion

Pediatric CAP hospitalizations with fever lasting > 7 days and tachypnea were at higher risk for progressing to severe pneumonia. A normal hematocrit level and a normal BMI are protective factors for severe pneumonia.

The Pediatric Emergency Research Network (PERN): A decade of global research cooperation in paediatric emergency care

OBJECTIVES

The Pediatric Emergency Research Network (PERN) was launched in 2009 with the intent for existing national and regional research networks in paediatric emergency care to organise globally for the conduct of collaborative research across networks.

METHODS

PERN has grown from five to eight member networks over the past decade. With an executive committee comprising representatives from all member networks, PERN plays a supportive and collaborative rather than governing role. The full impact of PERN's facilitation of international collaborative research, although somewhat difficult to quantify empirically, can be measured indirectly by the observed growth of the field, the nature of the increasingly challenging research questions now being addressed and the collective capacity to generate and implement new knowledge in treating acutely ill and injured children.

RESULTS

Beginning as a pandemic response studying H1N1 influenza risk factors in children, PERN research has progressed to multiple observational studies and ongoing global randomised controlled trials (RCTs). As a recent example, PERN has developed sufficient network infrastructure to enable the rapid initiation of a prospective observational study in response to the current COVID-19 pandemic.

CONCLUSIONS

Following its success with developing global research, the PERN goal now is to promote the implementation of scientific advances into everyday clinical practice by: (i) expanding the capacity for global RCTs; (ii) deepening the focus on implementation science; (iii) increasing attention to healthcare disparities; and (iv) expanding PERN's reach into resource-restricted regions. Through these actions, PERN aims to meet the needs of acutely ill and injured children throughout the world.

The Pediatric Emergency Research Network: A Decade of Global Research Cooperation in Pediatric Emergency Care

OBJECTIVES

The Pediatric Emergency Research Network (PERN) was launched in 2009 with the intent for existing national and regional research networks in pediatric emergency care to organize globally for the conduct of collaborative research across networks.

METHODS

The Pediatric Emergency Research Network has grown from 5- to 8-member networks over the past decade. With an executive committee comprising representatives from all member networks, PERN plays a supportive and collaborative rather than governing role. The full impact of PERN's facilitation of international collaborative research, although somewhat difficult to quantify empirically, can be measured indirectly by the observed growth of the field, the nature of the increasingly challenging research questions now being addressed, and the collective capacity to generate and implement new knowledge in treating acutely ill and injured children.

RESULTS

Beginning as a pandemic response with a high-quality retrospective case-controlled study of H1N1 influenza risk factors, PERN research has progressed to multiple observational studies and ongoing global randomized controlled trials. As a recent example, PERN has developed sufficient network infrastructure to enable the rapid initiation of a prospective observational study in response to the current coronavirus disease 2019 pandemic. In light of the ongoing need for translation of research knowledge into equitable clinical practice and to promote health equity, PERN is committed to a coordinated international effort to increase the uptake of evidence-based management of common and treatable acute conditions in all emergency department settings.

CONCLUSIONS

The Pediatric Emergency Research Network's successes with global research, measured by prospective observational and interventional studies, mean that the network can now move to improve its ability to promote the implementation of scientific advances into everyday clinical practice. Achieving this goal will involve focus in 4 areas: (1) expanding the capacity for global randomized controlled trials; (2) deepening the focus on implementation science; (3) increasing attention to healthcare disparities and their origins, with growing momentum toward equity; and (4) expanding PERN's global reach through addition of sites and networks from resource-restricted regions. Through these actions, PERN will be able to build on successes to face the challenges ahead and meet the needs of acutely ill and injured children throughout the world.
