Purpose: To describe the age of independence in intermittent self-catheterization (ISC) in a diverse patient population and identify factors associated with ISC in individuals with spina bifida.
Methods: Two hundred patients with myelomeningocele or lipomyelomeningocele, who were ⩾ 3 years of age and utilized catheterization for bladder management were included. Data regarding diagnosis, functional level of lesion, race, ethnicity, presence of shunt, method of catheterization, self-management skills, fine motor skills, and cognitive abilities were collected.
Results: Fifty-five percent of individuals were able to perform ISC with a mean age of 9.45 years (SD = 2.97) and 22.7% used a surgically created channel. Higher level of lesion and female gender were associated with a lower rate of ISC. Intellectual disability was present in 15% of the individuals able to perform ISC and in 40% of those not able to perform ISC (p= 0.0005). Existent self-efficacy regarding activities of daily living (i.e. dressing, bathing, skin care) were associated with ISC (p< 0.0001).
Conclusions: The average age of ISC emerged as a target for culturally-appropriate educational interventions to stimulate greater early independence. Future research on factors that may foster an 'independent spirit' early in childhood leading to self-management are warranted.
