Impact of home oxygen therapy on hospital stay for infants with acute bronchiolitis

Potential bed-day savings and caregiver perspectives of transitioning hospital-level management of infants with bronchiolitis to the home: a mixed-methods study

OBJECTIVE

Home management of infants admitted to hospital with bronchiolitis would alleviate pressure on hospital beds. We aim to understand the proportion of children requiring active care interventions (ie, oxygen, fluids), caregiver perspectives and potential impact of transitioning hospital-level care of infants with bronchiolitis to home.

METHODS

This is a mixed-methods study in an Australian tertiary paediatric hospital. Semistructured interviews with caregivers of infants with bronchiolitis focused on attitudes towards managing bronchiolitis at home. Interviews were analysed using inductive thematic analysis. Data on bronchiolitis admissions among infants aged 1-12 months were extracted from the electronic medical record from April 2016 to October 2020. Potential bed-days saved were calculated.

RESULTS

18 parents were interviewed, with themes emerging of 'hospital is safe', 'hospital incurs costs' and 'knowledge is power'. During 4.5 years, 2367 infants were admitted to hospital with bronchiolitis: a total of 4557 bed-days. Of these, 40% of infants were admitted for monitoring alone, 25% for nasogastric fluid support, 17% for oxygen therapy and 7.5% for both fluids and oxygen. 11% received treatments not currently feasible at home (high-flow oxygen, intravenous fluids). Oxygen therapy accounted for the largest number of bed-days (242 bed-days/year).

CONCLUSION

Managing bronchiolitis at home could have a substantial impact on hospital bed demand, with an estimated 344 bed-days saved per year if all interventions were offered. Parent willingness to transfer to home balances the perceived safety of the hospital versus the financial, logistic and emotional costs. Empowering parents with knowledge was seen as a substantial facilitator of supporting transition to the home.

Home Care for Bronchiolitis: A Systematic Review

CONTEXT

Bronchiolitis is the leading cause of pediatric hospital admissions. Hospital-at-Home (HAH) delivers hospital-level care at home, relieving pressure on the hospital system.

OBJECTIVES

We aimed to review the feasibility, acceptability, and safety of HAH for bronchiolitis, and assess the cost-impact to hospitals and society.

DATA SOURCES

Ovid Medline, Embase, Pubmed, Cochrane Library, CINAHL, and Web of Science.

STUDY SELECTION

Studies (randomized control trials, retrospective audits, prospective observational trials) of infants with bronchiolitis receiving HAH (oxygen, nasogastric feeding, remote monitoring). Studies were limited to English language since 2000.

DATA EXTRACTION

We reviewed all studies in duplicate for inclusion, data extraction, and risk of bias.

RESULTS

Ten studies met inclusion criteria, all for home oxygen therapy (HOT). One abstract on nasogastric feeding did not meet full inclusion criteria. No studies on remote monitoring were found. HOT appears feasible in terms of uptake (70%-82%) and successful completion, both at altitude and sea-level. Caregiver acceptability was reported in 2 qualitative studies. There were 7 reported adverse events (0.6%) with 0 mortality in 1257 patients. Cost studies showed evidence of savings, although included costs to hospitals only.

LIMITATIONS

Small number of studies with heterogenous study design and quality. No adequately powered randomized control studies.

CONCLUSIONS

Evidence exists to support HOT as feasible, acceptable, and safe. Evidence of cost-effectiveness remains limited. Further research is needed to understand the relevant impact of HAH versus alternative interventions to reduce oxygen prescribing. Other models of care looking at nasogastric feeding support and remote monitoring should be explored.

Etiology, clinical characteristics and coinfection status of bronchiolitis in Suzhou

Background

Bronchiolitis is a clinical syndrome commonly encountered in practice, particularly among infants and young children. To investigate the prevalence of pathogens in hospitalized children with bronchiolitis and study the clinical characteristics of bronchiolitis with or without coinfections.

Methods

We investigated the respiratory specimens and clinical data of 1012 children with bronchiolitis who were treated at the Children’s Hospital of Soochow University between November 2011 and December 2018. The nasopharyngeal aspirates were examined to detect viruses by direct immunofluorescence assay or polymerase chain reaction (PCR). Mycoplasma pneumoniae (MP) was tested by PCR and enzyme-linked immunosorbent assay.

Results

Of the 1134 children less than 2 years with bronchiolitis, 122 were excluded by exclusion criteria. Causative pathogen was detected in 83.2% (842 of 1012). The majority of these (614 [72.9%] of 842) were single virus infection. The most common pathogens detected were respiratory syncytial virus (RSV) (44.4%), MP (15.6%), and human rhinovirus (HRV) (14.4%). Coinfection was identified in 13.5% (137 of 1012) of the patients. Coinfection included mixed virus infection and virus infection with MP infection. Children with single virus infection had a higher rate of oxygen therapy compared with single MP infection.

Conclusions

The most common pathogen detected in children with bronchiolitis is RSV, followed by MP and HRV. Coinfection leads to a longer period of illness, increased severity of the symptoms and increased risk of hypoxemia.

Home oxygen therapy criteria, guidelines and protocols for hypoxia management in pediatric patients with acute bronchiolitis: a scoping review protocol

REVIEW OBJECTIVE/QUESTION

The objectives of this scoping review are: to explore existing literature related to discharge criteria, guidelines and protocols from hospitals or clinics that are being implemented for home oxygen therapy (HOT) in the management of hypoxia in pediatric patients with acute bronchiolitis, examine and conceptually map the evidence, and identify any gaps in the literature.The question of this review is: what discharge criteria, guidelines, and protocols are used for HOT in the management of hypoxia in pediatric patients with acute bronchiolitis?

Clinical practice guideline: the diagnosis, management, and prevention of bronchiolitis

This guideline is a revision of the clinical practice guideline, "Diagnosis and Management of Bronchiolitis," published by the American Academy of Pediatrics in 2006. The guideline applies to children from 1 through 23 months of age. Other exclusions are noted. Each key action statement indicates level of evidence, benefit-harm relationship, and level of recommendation. Key action statements are as follows:
