CHAMP For the Feeder: Tube Feeding Study

Training: After consent to the study- parents/LAR will undergo training on the CHAMP App use by the study staff. The CHAMP App will be downloaded on the parent/LAR mobile device or an iPad that has been locked to contain only the CHAMP App and patient portal with mobile device management of the device by CM.

In addition to approval to begin a weaning trial by the IDC team providing primary nutrition management-beginning the weaning process may include these requirements:

• Weight for length or body mass index (BMI) must be stable. For children who are premature, syndromic, small for gestational age, or intrauterine growth restriction patients, this is at the dietitian's and provider's discretion. For typically developing patients, weight for length BMI z-score must be > -2.
• . Weekly feeding therapy is not required for tube weaning but will be strongly encouraged.
• A feeding therapist has assessed oral motor skills and agrees that the patient has sufficient skills to take all their calories by mouth.

CHAMP App use: Families will be provided with a weighing scale for home use; access to the CHAMP App mobile application or an iPad with the app and myChildren's Mercy App (patient portal) installed, if they prefer, during the study period. Data quality and validity will be ensured through the training of the healthcare team on data entry and out-of-range limits for each data value collected via the CHAMP web portal data entry forms. All data will be stored on the secure CM CHAMP Azure software platform with secure encryption database features.

Healthcare team CHAMP web portal use: The study team will review data entered by parents twice a week and as needed with questions and red flag concerns reported by parents/LAR. They will communicate back to parents with messages in the patient portal for documentation of messages that can be seen by other gastroenterology (GI) staff (GI clinic messages).

The IDC tube weaning algorithm (attached) will be used as a guideline for awareness of tube weaning but any changes to volume, concentration, or formula type will be reviewed and approved by an IDC provider before communicating to families.

RPM data entered by parents will be reviewed weekly by the IDC healthcare team in a team meeting organized through weekly reports of active patients enrolled in the study. This meeting will include an IDC provider, nurse, and nutritionist at minimum. There will be a summary of full study patient reports and individual patient reports available to all healthcare team members throughout the study, and these reports will be especially useful during these weekly meetings.

The IDC team works with Gastroenterology staff and fellows for 24 hours a day call. The CHAMP app will have a service pager for GI and the on-call hospital network is also available at any time for parents/LAR. On-call GI staff will be able to see feeding and weight data in Cerner under results review and CHAMP App. Videos are only available in the CHAMP web portal at champ.childrensmercy.org

Recommendation and timing for removal of feeding tubes will be up to the healthcare team alone. This event will be documented for date/time but is not a study-related intervention recommended through CHAMP App.

Additional measures to evaluate study results include:

Demographics - child and family measures: The study team will collect data on the child and family from the electronic medical record, including, but not limited to, infant medical conditions, feeding interventions, in-person healthcare visits with IDC and other specialists, language spoken, the distance of home residence from the hospital, in-home services used (Early Intervention, Physical Therapy, Occupational therapy, speech).

Nutritional measures: The study team will obtain the child's weight, length, and head circumference at birth and enrollment from the electronic medical record. The investigators will also obtain the following from the electronic medical record: weight for age and z-scores calculated by gender, weight percentiles, length/weight, mid-upper arm circumference (MUAC,) and head circumference. The investigators will use the CHAMP App to track weight at weekly intervals and obtain via parental report. There will be a weekly review, as well as on an as-needed basis, if sooner than weekly, by the IDC's research team, providers and nutrition team.

Healthcare team measures: The IDC team's periods of nutrition interventions will be evaluated for frequency of communication, including feeding interventions with families, volume changes, feeding routes, concentrations, and weight reporting frequency charted in the EMR. The time to first visit with the clinical team after referral to the IDC team, the rate of cancellation/no-show visits, and the number of patients on the wait list for enrollment in the clinical program will also be collected.

Family experience measures: Rate of first patient appointment attended, rate of attrition though never seen, cancellation and no-show appointments, time to first appointment after confirmation of visit in the calendar system, rate of follow-up frequency, graduation from the program with 100% calories by mouth with age-appropriate weight gain vs. attrition rates. Time to the healthcare recommendation of removal of feeding tube after the use of CHAMP app (by type nasogastric (NG) and gastrostomy - g-tube).

Technology measures by parents: Using the CHAMP App, the study team will track parent reported feeding volumes by mouth and tube, weights from home scales, videos of eating, and time to all feedings by mouth.

Technology adherence measures: The study team will track parent use of the app through tracking data on 1) app initiation, the first day of data transfer of CHAMP App data after enrollment; 2) implementation, the amount and type (feeding volumes, type, concentration, food amount, types, and weights) of asynchronous remote patient monitoring data received at the recommended intervals; and 3) discontinuation, the time of last data sent to the healthcare team.
