Brief summary

The purpose of this study is to identify the optimal deimplementation strategies for an overused practice: continuous pulse oximetry monitoring of children hospitalized with bronchiolitis who are not receiving supplemental oxygen.

Interventions

Educational outreach includes staff-targeted educational materials and outreach sessions summarizing the current evidence and guideline recommendations for pulse oximetry use in bronchiolitis.

BEHAVIORALAudit & Feedback (unit level)

Weekly unit-level feedback of each hospital's guideline-concordant practice will be distributed to sites in the form of a visual dashboard that includes comparisons over time and between hospitals. The dashboard will then be shared locally on a weekly basis with clinicians in person and electronically.

BEHAVIORALAudit & Feedback (real time, individual-level)

Real-time feedback will occur at the individual clinician level. When collecting data on an individual patient, data collectors encountering guideline-discordant continuous monitoring are empowered to briefly ask any available clinician responsible for that patient's care, in a nonjudgmental way, about indications for monitoring that patient. The clinician is ultimately responsible for deciding if any changes are indicated.

BEHAVIORALClinical Pathway Integrated into Electronic Health Record

Clinical pathways guide clinicians step-by-step through evidence-based care. Based on the existing guidelines for physiologic monitoring in bronchiolitis, the pathway will clearly specify (a) situations when it is appropriate to initiate intermittent SpO2 measurement instead of continuous SpO2 monitoring, and (b) when it is appropriate to discontinue continuous SpO2 monitoring altogether, and transition to intermittent SpO2 measurement. In order to be visible to clinicians as they perform patient care, the pathway will be integrated into the electronic health record at sites randomized to this intervention.

Design outcomes

Primary

MeasureTime frameDescription
Deimplementation SustainmentData from the baseline phase (approximately 7 months) was compared to data from the sustainment phase (approximately 4 months). Only data from baseline and sustainment phases are used in this calculation.The primary outcome specified in the protocol is deimplementation sustainment, a "difference in differences" outcome based on statistical comparisons based on pulse oximetry overuse across trial phases and arms. Pulse oximetry overuse is operationally defined as percent of patient observations monitored using continuous pulse oximetry while not receiving supplemental oxygen (measured using direct observation). The least metabolized form of the data for pulse oximetry overuse, raw proportions across trial phases and arms, is reported here. Results of the specific analysis used to report the trial's pre-specified primary outcome of deimplementation sustainment is reported in Statistical Analysis 1.

Secondary

MeasureTime frameDescription
Count of Observations During Which the Patient Was Not Receiving Supplemental Oxygen and Yet Was Continuously Monitored Using Pulse Oximetry During the Baseline Phase of the TrialThis measure used data from the baseline phase (approximately 7 months).This measure is assessed as the count of patient observations monitored using continuous pulse oximetry while not receiving supplemental oxygen (measured using direct observation) in the baseline phase. In order to assist in interpretation, this can also be viewed below as a proportion or a percent of the total number of observations. The denominator is the count of observations of patients not receiving supplemental oxygen. The numerator is the count of observations of patients not receiving supplemental oxygen who are also monitored using continuous pulse oximetry. The numerator count is divided by the denominator count to calculate a proportion. The proportion is multiplied by 100 to obtain a percent. This is expressed below as a count with the percentage automatically calculated by the clinicaltrials.gov system.
Count of Observations During Which the Patient Was Not Receiving Supplemental Oxygen and Yet Was Continuously Monitored Using Pulse Oximetry During the Active Deimplementation Phase of the TrialData from the active deimplementation phase (approximately 5 months).This measure is assessed as the count of patient observations monitored using continuous pulse oximetry while not receiving supplemental oxygen (measured using direct observation) in the active deimplementation phase. In order to assist in interpretation, this can also be viewed below as a proportion or a percent of the total number of observations. The denominator is the count of observations of patients not receiving supplemental oxygen. The numerator is the count of observations of patients not receiving supplemental oxygen who are also monitored using continuous pulse oximetry. The numerator count is divided by the denominator count to calculate a proportion. The proportion is multiplied by 100 to obtain a percent. This is expressed below as a count with the percentage automatically calculated by the clinicaltrials.gov system.
Count of Observations During Which the Patient Was Not Receiving Supplemental Oxygen and Yet Was Continuously Monitored Using Pulse Oximetry During the Sustainment Phase of the TrialData from the sustainment phase (approximately 4 months).This measure is assessed as the count of patient observations monitored using continuous pulse oximetry while not receiving supplemental oxygen (measured using direct observation) in the sustainment phase. In order to assist in interpretation, this can also be viewed below as a proportion or a percent of the total number of observations. The denominator is the count of observations of patients not receiving supplemental oxygen. The numerator is the count of observations of patients not receiving supplemental oxygen who are also monitored using continuous pulse oximetry. The numerator count is divided by the denominator count to calculate a proportion. The proportion is multiplied by 100 to obtain a percent. This is expressed below as a count with the percentage automatically calculated by the clinicaltrials.gov system.
Duration of Oxygen SupplementationUp to 4 yearsThe oxygen supplementation duration is the total duration of time during which a patient is documented as receiving supplemental oxygen during hospitalization.
Length of Hospital StayUp to 4 yearsThe length of hospital stay is the duration of time that elapses between the time a patient is admitted with bronchiolitis to an inpatient unit of the hospital until the time they are discharged from the hospital, using data manually abstracted from the electronic health record chart.

Participant flow

Recruitment details

This is a cluster-randomized trial with randomization at the hospital level. The trial had 4 phases: Baseline, Active Deimplementation, Sustainment, and Exploratory. Each phase had a mutually exclusive, separate group of participants enrolled - participants did not continue their participation across phases. For example, all of the patients in the baseline phase are different from all of the patients in the sustainment phase.

Pre-assignment details

The trial had 4 phases: Baseline, Active Deimplementation, Sustainment, and Exploratory. The primary outcome uses data from bronchiolitis patients from the first 3 phases only. The fourth phase, labeled Exploratory, included a subset of sites and was used exclusively for exploratory outcome measurement in bronchiolitis patients. The trial also included other populations, including parents/guardians, and staff/coaches. These other populations were exclusively used for exploratory outcomes.
