OBJECTIVE: To examine the health insurance experience and out-of-pocket
health care costs of families with a child with IDDM. RESEARCH DESIGN AND
METHODS: A case-control study of 197 families with a child with IDDM and
142 control families with no diabetic children was conducted. IDDM-affected
families were identified from the Allegheny County IDDM Registry. Brothers
and sisters of the parents in the IDDM-affected families were asked to
participate as control subjects. Health insurance coverage and the money
that families spent on health care services and supplies not reimbursed by
insurance (out-of-pocket costs) were assessed by questionnaire. RESULTS: No
difference was found between the IDDM-affected and control families in the
percentages with or without insurance. Families with low household incomes
($10,000-$19,999) were at the greatest risk for having no insurance. While
coverage provided by private plans was similar between the IDDM-affected
and control families, many families had no reimbursement for insulin (10%),
syringes (10%), or blood testing strips (30%). Out-of-pocket expenses were
56% higher in the IDDM-affected families than in the control families.
Seventeen percent of the IDDM-affected families had expenses over 10% of
their household income. This particularly affected families with low
household incomes. Pre-existing illness clauses and insurance denial
affected only a small proportion of the case families. CONCLUSIONS: These
data illustrate that most families with a child with IDDM have health
insurance, yet still incur larger out-of-pocket health care costs than do
families without the presence of diabetes. IDDM-affected families likely
face a number of economic decisions regarding health insurance and the use
of health care.
