Remote Monitoring of Patient- and Family-Generated Health Data in Pediatrics

Telemonitoring of pediatric asthma in outpatient settings: A systematic review

Telemonitoring technologies are rapidly evolving, offering a promising solution for remote monitoring and timely management of asthma acute episodes. We aimed to describe current pediatric asthma telemonitoring technologies. A systematic review was conducted until September 2023 on Medline, Scopus, and Web of Science. We included studies of children (0-18 years) with asthma or recurrent wheezing whose respiratory condition was telemonitored outside the healthcare setting. A narrative synthesis was performed. We identified 40 telemonitoring technologies described in 40 studies. The more frequently used technologies for telemonitoring were mobile applications (n = 21) and web-based systems (n = 14). Telemonitoring duration varied between 2 weeks and 32 months. Data collection included asthma symptoms (n = 30), patient-reported outcome measures (PROMs) (n = 11), spirometry/peak flow readings (n = 20), medication adherence (n = 17), inhaler technique (n = 3), air quality (n = 2), and respiratory sounds (n = 2). Both parents and children were the technology target users in most studies (n = 23). Technology training was reported in 23 studies of which 3 provided ongoing support. Automatic feedback was found in 30 studies, mostly related with asthma control. HCP were involved in data management in 27 studies. Technologies were tested in samples from 4 to 327 children, with most studies including school-aged children and/or adolescents (n = 38) and eight including preschool children. This review provides an overview of existing technologies for the outpatient telemonitoring of pediatric asthma. Specific technologies for preschool children represent a gap in the literature that needs to be specifically addressed in future research.

Equitable implementation of a precision digital health program for glucose management in individuals with newly diagnosed type 1 diabetes

Few young people with type 1 diabetes (T1D) meet glucose targets. Continuous glucose monitoring improves glycemia, but access is not equitable. We prospectively assessed the impact of a systematic and equitable digital-health-team-based care program implementing tighter glucose targets (HbA1c < 7%), early technology use (continuous glucose monitoring starts <1 month after diagnosis) and remote patient monitoring on glycemia in young people with newly diagnosed T1D enrolled in the Teamwork, Targets, Technology, and Tight Control (4T Study 1). Primary outcome was HbA1c change from 4 to 12 months after diagnosis; the secondary outcome was achieving the HbA1c targets. The 4T Study 1 cohort (36.8% Hispanic and 35.3% publicly insured) had a mean HbA1c of 6.58%, 64% with HbA1c < 7% and mean time in the range (70-180 mg dl-1) of 68% at 1 year after diagnosis. Clinical implementation of the 4T Study 1 met the prespecified primary outcome and improved glycemia without unexpected serious adverse events. The strategies in the 4T Study 1 can be used to implement systematic and equitable care for individuals with T1D and translate to care for other chronic diseases.

Codesign of remote data collection for chronic management of pediatric 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.

Remote monitoring for neonates requiring continued nasogastric tube feeding: implementation, patient characteristics, and early outcomes

OBJECTIVE

Our neonatal intensive care unit utilizes remote patient monitoring to facilitate hospital discharge with nasogastric tube (NGT) feeds. Program implementation, patient characteristics, and initial outcomes are described.

STUDY DESIGN

Data was collected prospectively in this implementation study. Descriptive statistics define weight gain, number of NGT feed days, number of days on monitoring, and physician time spent. Patient characteristics, readmissions, and implementation details are described.

RESULTS

One-hundred and four babies consented to and completed data collection. Average weight gain on monitoring was 31.4 g/day (SD 10.2). Eighty-nine babies (85.6%) achieved full oral feeds while on the program, requiring a median 5 NGT feed days (IQR 2-13) and a median 15 days on monitoring (IQR 11-27). Average physician time spent was 9.1 min per day (SD 3.7). Six babies (5.8%) had unscheduled readmissions while on the program.

CONCLUSION

Remote monitoring programs can facilitate discharge for babies with continued NGT needs.

Telehealth Use in a National Pediatric Weight Management Sample During the COVID-19 Pandemic

Background: This study aimed to assess the implementation and access to telehealth-delivered pediatric weight management (PWM) during the initial phase of the COVID-19 pandemic at six US PWM programs (PWMP) using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Methods: The COVID-19 period (COVID) was defined in this retrospective, multisite study as the time when each site closed in-person care during 2020. The Pre-COVID period (Pre-COVID) was an equivalent time frame in 2019. Patients were stratified by visit completion status. Patient characteristics for COVID and Pre-COVID were compared to examine potential changes/disparities in access to care. Results: There were 3297 unique patients included across the six sites. On average, telehealth was initiated 4 days after in-person clinic closure. Compared with Pre-COVID, COVID (mean duration: 9 weeks) yielded fewer total completed visits (1300 vs. 2157) and decreased revenue (mean proportion of nonreimbursed visits 33.30% vs. 16.67%). Among the completed visits, COVID included a lower proportion of new visits and fewer patients who were male, non-English speaking, Hispanic, or Asian and more patients who were Black or lived ≥20 miles from the program site (p < 0.05 for all). Among no-show/canceled visits, COVID included more patients who had private insurance, older age, or a longer time since the last follow-up. Conclusion: Rapid implementation of telehealth during COVID facilitated continuity of PWM care. Clinic volume and reimbursement were lower during COVID and differences in the patient population reached by telehealth emerged. Further characterization of barriers to telehealth for PWM is needed.

Home monitoring in asthma: towards digital twins

PURPOSE OF REVIEW

We highlight the recent advances in home monitoring of patients with asthma, and show that these advances converge towards the implementation of digital twin systems.

RECENT FINDINGS

Connected devices for asthma are increasingly numerous, reliable and effective: new electronic monitoring devices extend to nebulizers and spacers, are able to assess the quality of the inhalation technique, and to identify asthma attack triggers when they include a geolocation function; environmental data can be acquired from databases and refined by wearable air quality sensors; smartwatches are better validated. Connected devices are increasingly integrated into global monitoring systems. At the same time, machine learning techniques open up the possibility of using the large amount of data collected to obtain a holistic assessment of asthma patients, and social robots and virtual assistants can help patients in the daily management of their asthma.

SUMMARY

Advances in the internet of things, machine learning techniques and digital patient support tools for asthma are paving the way for a new era of research on digital twins in asthma.

Implementation and Evaluation of a Wraparound Virtual Care Program for Children with Medical Complexity

Objectives: Children and adolescents with medical complexity benefit from care coordination and specialized pediatric care, but many access barriers exist. We implemented a virtual wraparound model to support patients with medical complexity and their families and used an economic framework to measure outcomes. Methods: Children with medical complexity were identified and enrolled in a virtual complex care program with a dedicated multidisciplinary team, which provided care coordination, education, parental support, acute care triage, and virtual visits. A retrospective pre- and postanalysis of data obtained from the Hospital Industry Data Institute (HIDI) database measured inpatient, outpatient, and emergency department (ED) utilization and charges before implementation and during the 2-year program. Results: Eighty (n = 80) children were included in the economic evaluation, and 75 had sufficient data for analysis. Compared to the 12 months before enrollment, patients had a 35.3% reduction in hospitalizations (p = 0.0268), a 43.9% reduction in emergency visits (p = 0.0005), and a 16.9% reduction in overall charges (p = 0.1449). Parents expressed a high degree of satisfaction, with a 70% response rate and 90% satisfaction rate. Conclusions: We implemented a virtual care model to provide in-home support and care coordination for medically complex children and adolescents and used an economic framework to assess changes in utilization and cost. The program had high engagement rates and parent satisfaction, and a pre/postanalysis demonstrated statistically significant reduction in hospitalizations and ED visits for this high-cost population. Further economic evaluation is needed to determine sustainability of this model in a value-based payment system.

High Parental Concern in Children With Medical Complexity: An Early Indicator of Illness

OBJECTIVES

High concern about child's health is a common reason parents of children with medical complexity (CMC) seek care in emergency departments and hospitals. Factors driving parental concern are unknown. This study explores associations of parent's sociodemographic and child's clinical factors with high parental concern.

PATIENT AND METHODS

Secondary analysis of a pilot study of CMC and parents who used daily for 3 months MyChildCMC, a home monitoring app. Parents recorded their child's vital signs (temperature, heart rate, respiratory rate, oximetry), symptoms (pain, seizures, fluid intake/feeding, mental status), and oxygen use, and received immediate feedback. Parents rated their child's health concern on a 4-point Likert scale. Concern scores were dichotomized (3-4 = high, 1-2 = low) and modeled in a mixed-effects logistic regression to explore important associations.

RESULTS

We analyzed 1223 measurements from 24 CMC/parents, with 113 (9.24%) instances of high concern. Child factors associated with high parental concern were increased pain (odds ratio [OR], 5.10; 95% confidence interval [CI], 2.53-10.29; P < .01), increased oxygen requirement (OR, 28.91; 95% CI, 10.07-82.96; P < .01), reduced nutrition/fluid intake (OR, 71.58; 95% CI, 13.01-393.80; P < .01), and worsened mental status (OR, 2.15; 95% CI, 1.10-4.17, P = .02). No other associations existed.

CONCLUSIONS

Changes in CMC's clinical parameters were associated with high concern, which may be an early indicator of acute illness in CMC when it is the primary complaint. Monitoring and responding to high parental concerns may support CMC care at home.

Using a centralized nursing team to implement multi-specialty pediatric remote patient monitoring programs

BACKGROUND

The increase in telehealth usage has sustained since the beginning of the COVID-19 pandemic. While Remote Patient Monitoring (RPM) programs are abundantly used in the management of adults, pediatric RPM programs remain rare.

METHODS

An RPM department was developed to serve several, multi-specialty pediatric programs. This department uses a centralized nursing team that manages all patients enrolled in RPM programs. Each program is unique and created in partnership with the centralized nurses and the ambulatory care teams. The various programs allow for transmission of patient- and caregiver-generated health data and consistent communication between the patient or caregiver and the managing providers, allowing for real-time plan adaptation.

FINDINGS

Over 1200 patients have been managed through the 18 various RPM programs. Approximately 300 patients are monitored each month by the centralized nursing team. Patient and caregiver experience has been high due to resources offered including on-demand video visits and text messaging with the nursing team.

DISCUSSION

Multi-specialty RPM departments help to expand the reach of an institution and provide care to more patients. Quality improvement must be ongoing to ensure equity of participation and perceived benefit of the programs for both providers and patients and caregivers.

APPLICATION TO PRACTICE

Pediatric RPM programs can improve patient care delivery by decreasing days away from home while improving access to care. Ensuring equitable opportunity for patient participation is imperative in achieving success for an RPM department.

At-home end-tidal carbon dioxide measurement in children with invasive home mechanical ventilation

BACKGROUND

Carbon dioxide concentration trending is used in chronic management of children with invasive home mechanical ventilation (HMV) in clinical settings, but options for end-tidal carbon dioxide (EtCO₂ ) monitoring at home are limited. We hypothesized that a palm-sized, portable endotracheal capnograph (PEC) that measures EtCO₂ could be adapted for in-home use in children with HMV.

METHODS

We evaluated the internal consistency of the PEC by calculating an intraclass correlation coefficient of three back-to-back breaths by children (0-17 years) at baseline health in the clinic. Pearson's correlation was calculated for PEC EtCO₂ values with concurrent mean values of in-clinic EtCO₂ and transcutaneous CO₂ (TCM) capnometers. The Bland-Altman test determined their level of agreement. Qualitative interviews and surveys assessed usability and acceptability by family-caregivers at home.

RESULTS

CO₂ values were collected in awake children in varied activity levels and positions (N = 30). The intraclass correlation coefficient for the PEC was 0.95 (p < 0.05). The correlation between the PEC and in-clinic EtCO₂ device was 0.85 with a mean difference of -3.8 mmHg and precision of ±1.1 mmHg. The correlation between the PEC and the clinic TCM device was 0.92 with a mean difference of 0.2 mmHg and precision of ±1.0. Family-caregivers (N = 10) trialed the PEC at home; all were able to obtain measurements at home while children were awake and sometimes asleep.

CONCLUSIONS

A portable, noninvasive device for measuring EtCO₂ was feasible and acceptable, with values that trend similarly to currently in-practice, outpatient models. These devices may facilitate monitoring of EtCO₂ at home in children with invasive HMV.
