Age and factors associated with self-clean intermittent catheterization in patients with spina bifida.

PURPOSE

The purpose of this study is twofold: 1) to determine the age when a child with spina bifida (SB) will most likely transition from caregiver clean intermittent catheterization (CIC) to self-CIC, and 2) to identify factors associated with self-CIC in children older than that age.

METHODS

This is a retrospective, single-institution cohort study of individuals with SB. Data were collected prospectively as part of the National Spina Bifida Patient Registry. For Aim 1, we identified all individuals who perform self-CIC and who had a documented transition from caregiver-CIC. We then determined the age of transition to self-CIC. For Aim 2, we compared individuals over age 10 years (age cutoff determined by Aim 1) who use self-CIC to those who use caregiver-CIC to determine what variables were associated with self-CIC.

RESULTS

From our SB population, 206 individuals used self-CIC. Of these, 64 patients had documented ages of transition from caregiver- to self-CIC. 46 (71.9%) and 56 (87.5%) patients had transitioned to self-CIC by 10 and 14 years, respectively. For Aim 2, we used age 10 as a cutoff, based on the findings from Aim 1, and found that 287/696 patients were ⩾ 10 years and using CIC. Factors independently associated with lower likelihood of self-CIC were thoracic spinal lesions (odds ratio (OR) 0.45) and Medicaid insurance (OR 0.24).

CONCLUSIONS

The ages at self-CIC transition vary, although most patients transition by age 10. Thoracic-level spinal lesions and Medicaid insurance are associated with lower odds of self-CIC.
