Insights
Remote patient monitoring (RPM) is feasible and acceptable for children on invasive home mechanical ventilation (IHMV). This technology captures clinically significant vital sign changes during ventilator breaks, improving IHMV management.
Area of Science:
- Pediatric Pulmonology
- Biomedical Engineering
- Health Informatics
Background:
- Outpatient monitoring of children with invasive home mechanical ventilation (IHMV) is crucial but faces access challenges.
- This study investigated the feasibility and acceptability of remote data collection for chronic IHMV management.
Purpose of the Study:
- To assess the feasibility and acceptability of remote patient monitoring (RPM) for children using IHMV.
- To evaluate the clinical utility of RPM in capturing vital sign changes during ventilator use.
Main Methods:
- A codesign study involving an IHMV program, nurses, and parents of children (0-17 years) using IHMV.
- Parents utilized an RPM bundle for 8 weeks to collect physiological data (HR, RR, SpO2, EtCO2, ventilator pressures).
- User feedback was analyzed using qualitative methods and the System Usability Scale (SUS); mixed-effects models analyzed vital sign differences.
Main Results:
- RPM data were collected for a mean of 83.7% of weeks, with high usability scores (Nurses: 84.8, Parents: 91.8).
- Over 90% of parents found RPM feasible and relevant for their child's care.
- Significant increases in end-tidal carbon dioxide (EtCO2) and respiratory rate (RR) were observed during ventilator breaks.
Conclusions:
- Remote patient monitoring (RPM) is a feasible and acceptable method for managing children with IHMV.
- RPM effectively captures clinically meaningful vital sign variations, supporting its utility in IHMV care.
- This technology enhances the management of children requiring invasive home mechanical ventilation.
Introduction:
Outpatient monitoring of children using invasive home mechanical ventilation (IHMV) is recommended, but access to care can be difficult. This study tested if remote (home-based) data collection was feasible and acceptable in chronic IHMV management.
Methods:
A codesign study was conducted with an IHMV program, home nurses, and English- and Spanish-speaking parent-guardians of children using IHMV (0-17 years; n = 19). After prototyping, parents used a remote patient monitoring (RPM) bundle to collect patient heart rate, respiratory rate (RR), oxygen saturation, end-tidal carbon dioxide (EtCO2 ), and ventilator pressure/volume over 8 weeks. User feedback was analyzed using qualitative methods and the System Usability Scale (SUS). Expected marginal mean differences within patient measures when awake, asleep, or after a break were calculated using mixed effects models.
Results:
Patients were a median 2.9 years old and 11 (58%) took breaks off the ventilator. RPM data were entered on a mean of 83.7% (SD ± 29.1%) weeks. SUS scores were 84.8 (SD ± 10.5) for nurses and 91.8 (SD ± 10.1) for parents. Over 90% of parents agreed/strongly agreed that RPM data collection was feasible and relevant to their child's care. Within-patient comparisons revealed that EtCO2 (break-vs-asleep 2.55 mmHg, d = 0.79 [0.42-1.15], p < .001; awake-vs-break 1.48, d = -0.49 [0.13-0.84], p = .02) and RR (break-vs-asleep 16.14, d = 2.12 [1.71-2.53], p < .001; awake-vs-break 3.44, d = 0.45 [0.10-0.04], p = .03) were significantly higher during ventilator breaks.
Conclusions:
RPM data collection in children with IHMV was feasible, acceptable, and captured clinically meaningful vital sign changes during ventilator breaks, supporting the clinical utility of RPM in IHMV management.
