Caregiver Burden and Preventive Dental Care Use for US Children with Special Health Care Needs: A Stratified Analysis Based on Functional Limitation

Abstract

Objectives-To evaluate the association between caregiver burden and preventive dental care use for children with special health care needs (CSHCN) and assess if caregiver burden explains the relationship between child-and family-level characteristics and preventive dental care use.Methods-Samples of U.S. CSHCN ages 3-17 years with a functional limitation (n=7,559) and those without (n=26,345) were derived from the 2005-2006 National Survey of CSHCN. We generated structural equation models, stratified by functional limitation, to describe the relationships between caregiver burden and preventive dental utilization. We measured caregiver burden using six items on whether the child's health condition impacted work, time spent on health management, and finances.Results-About 80.9% of CSHCN used preventive dental care. Higher levels of caregiver burden were associated with significantly lower odds of preventive dental care use for CHSCN with a functional limitation (β=−0.06; P<0.001) and those without (β=−0.07; P<0.001). For CSHCN with a functional limitation, family poverty and being uninsured were significantly associated with greater caregiver burden and less preventive dental use. Findings were similar for CSHCN without a functional limitation, except that lower caregiver education was also associated with greater caregiver burden and less preventive dental care use.Conclusions-Caregiver burden is potential barrier to preventive dental care use for CSHCN and explains the relationship between child-and family-level characteristics and preventive dental care use. Interventions to improve the oral health of CSHCN should include strategies to reduce caregiver burden, especially within socioeconomically vulnerable families.

Dental Homes for Children With Autism

“…13,46 Providing families of children with ASD with additional resources, like respite care, could help more caretakers establish and maintain dental homes for children with ASD. 47,48 Second, in contrast to dental provider reluctance to treat children with ASD identified in prior studies, 16,17 Iowa dentists may be increasingly likely to treat Medicaid-enrolled children with ASD as they are Medicaid-enrolled children without ASD, with 58% of Iowa dentists accepting new Medicaid patients. 49 One concern is that despite being equally as likely to have dental homes, Medicaid-enrolled children with ASD may continue to have unmet dental needs because of factors that increase their caries risk, consistent with the finding that Medicaid-enrolled children with ASD are significantly less likely to use preventive dental care.…”

Non-traumatic Dental Condition-Related Emergency Department Visits and Associated Costs for Children and Adults with Autism Spectrum Disorders

“…First, even though children with ASD have difficulties accessing routine office-based dental care and have unmet needs, they may be able to obtain treatment for dental problems before ED visits become necessary. Addressing symptomatic dental problems may be a high priority for parents of children with ASD, whereas routine preventive care might have been postponed because of alternative priorities and lack of urgency (Chi et al 2013). Dentists may also be more willing to see children with ASD with symptomatic dental problems.…”

Caregiver Burdens and Preventive Dental Care for Children with Autism Spectrum Disorder, Developmental Disability and/or Mental Health Conditions: National Survey of CSHCN, 2009–2010

“…Time-related burden corresponded with the caregiver providing over ten hours of care per week to the CASD/DD/MHC. The mean family time burden related to mental and physical disorders was 13.9 (SE=.6) hours per week in a global analysis (Viana et al 2013), however other research conducted in the US used 10 hours per week as caregiver burden for CSHCN (Chi et al 2014). …”
