Intermittent Versus Continuous Pulse Oximetry Monitoring of Infants Admitted for Bronchiolitis

Hypoxia Clinical Trial

Official title: Intermittent Versus Continuous Pulse Oximetry Monitoring of Infants Admitted for Bronchiolitis

Status Completed

Clinical Trial Summary

Bronchiolitis is a lower respiratory tract infection (LRTI) syndrome cause by different types of viruses and occurs in young children. Although bronchiolitis is a widespread and fairly common illness in children, pediatricians vary significantly in how it is treated. This includes how children are monitored for their oxygen status when not receiving supplemental oxygen. Studies suggest that continuous pulse oximetry measurement of children admitted to the hospital with bronchiolitis regardless of use of supplemental oxygen prolongs their hospital stay. This increases the cost of care for these patients and increases their risk of hospital-associated complications. This study is a randomized trial of continuous pulse oximeter use in patients admitted with bronchiolitis versus transitioning patients not requiring oxygen to intermittent pulse oximetry monitoring. The investigators hypothesize that this will decrease length of stay as well as associated costs of care and number of medical interventions performed in the hospital.

Clinical Trial Description

Background: Bronchiolitis is a lower respiratory tract infection (LRTI) syndrome caused by different viruses. It is the most common LRTI in children under 24 months old, accounting for approximately 90,000 hospitalizations annually and costing over $700 million in children under 12 months. Health care providers vary in diagnosis and management, however. In 2006 the American Academy of Pediatrics (AAP) released guidelines for bronchiolitis management in an effort to standardize clinical practice. Part of these guidelines recommends patients admitted to the hospital receive supplemental oxygen if they are persistently hypoxic, which is defined as pulse oximeter readings persistently below 90%. However, this recommendation is based on expert opinion. Research has previously shown healthy infants routinely experience brief episodes of decreased oxygen levels while sleeping without significant health effects. Other studies demonstrate no relationship between short intervals of transient or mildly decreased oxygen levels and long-term mental or developmental delays. Furthermore, children with bronchiolitis remain hospitalized longer without any appreciable improvement in the course or outcome of their illness when continuously monitored for oxygen level. Widespread pulse oximeter use has increased hospitalization rates over 250%, and close monitoring increases length of stay for children who otherwise could be discharged home. The 2006 guidelines discourage continuous pulse oximetry monitoring in children not requiring supplemental oxygen, but health care providers routinely ignore this recommendation. No studies have assessed the impact of more strictly adhering to the practices recommended by the AAP. Research Procedures: This is a randomized control study and is a multi-site collaboration with University of Missouri Children's Hospital in Columbia, Missouri. Children admitted to the study sites with bronchiolitis will be batch randomized (i.e. randomized separately at each site) to undergo either continuous pulse oximetry monitoring throughout the entire hospitalization or receive intermittent monitoring when not on supplemental oxygen. Patients will additionally receive all care standard to the management of their illness. Of note, the proposed intervention is the recommended standard of care for oxygen monitoring compared to the general practice used at both study sites. Researchers will then review charts after discharge for length of stay, number of medical interventions performed, diagnostic testing completed, and treatments provided. Cost of stay for patients in each group will be estimated and compared as well. Patients will be involved in the study for their entire admission. ;
