The purpose of the study is to develop a comprehensive program to increase early initiation of self-catheterization in children with Spina Bifida.
This will be a prospective open label randomized control trial. Patients and caregivers/guardians in the intervention arm will be enrolled in a comprehensive program that utilizes behavioral economic theory to incentivize initiation of independent CIC. The study population will be patients aged 4 to 12 years old with diagnosis of spina bifida, including meningocele and myelomeningocele, as defined by International Classification of Diseases, 10th revision (ICD10).
This study will look at behavioral interventions. There are no additional physical risks to participation in the study. Patient demographics will be reported using descriptive statistics. Study team will use Kaplan-Meier curves to demonstrate and compare the probability of achieving independent CIC over time between the study arms.
There are three study arms to which patients will be randomized in block randomization fashion with goal recruitment totaling 45 patients. Randomization will begin with Arm 1 and Arm 2 in a 1:1 ratio for the first 20 patients, 10 patients per arm. If accrual is reasonably brisk, we will expand our recruitment to Arm 3 which will then be conducted in a 1:1:3 block randomization for the remaining 25 patients with a total of 15 patients per arm. If accrual is slow and recruitment goal will not be met by expected date, we will continue accrual to Arm 1 and Arm 2 without including Arm 3. Randomization will be performed via NIH clinical trial randomization tool.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control (Arm #1) | No Intervention | CIC will be discussed with caretakers & patients during their appointment and they will be given the instruction sheet to take home. They will not have a follow-up appointment scheduled. Research team will call them to check if the patient is able to perform CIC independently. If they can, a visit will be scheduled for them to demonstrate this in clinic. | |
| Present Bias without Loss Aversion (Arm #2) | Experimental | CIC will be discussed with caretakers & patients during their appointment and they will be given the instruction sheet to take home. Child will receive a prize (~$5-20 in value) for every CIC step completed. They will follow-up in clinic in 3 months (or earlier) to demonstrate their CIC ability. If they can demonstrate this ability, they will receive a large prize (~$30-50 in value) |
|
| Present Bias with Loss Aversion (dependent on accrual) (Arm #3) | Experimental | CIC will be discussed with caretakers & patients during their appointment and they will be given the instruction sheet to take home. Child will pick a prize for every CIC step completed. They will follow-up in clinic in 3 months (or earlier) to demonstrate their CIC ability. All of the prizes that the child picked will be given only if fully-independent CIC is demonstrated. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Present Bias without Loss Aversion | Behavioral | Small prize for each step completed; large prize for independent CIC |
|
| Measure | Description | Time Frame |
|---|---|---|
| Number of participants with independent CIC (Clean Intermittent Catheterization) | Upon notification from the caregiver that a child is ready to demonstrate self-CIC, they will come to the Duke Pediatric Urology or Duke Spina Bifida Clinic and meet with study personnel. Participating children will be given supplies and asked to perform CIC in private. Prior to CIC, they will have a bladder scan to measure the pre-CIC bladder volume. After they perform CIC, another bladder scan will be performed to evaluate the post-CIC bladder volume. An adequate post-CIC volume will be defined as less than 20% of the age-appropriate bladder volume. | 3 months |
