Conditions were a subset of 25 conditions that represent about 80% of KP's health care spending (Ray, 2000), plus ADHD, behavior problems, and otitis media, which were considered a priori to be conditions more prevalent among children. The subset consists of those conditions that occurred in at least 2% of either the AODD family members or the comparison family members, and excluded pregnancy. Conditions of the uterus and headache met the 2% criterion, but are not included in this table because there were no significant differences in these conditions in any of the comparisons.
Conditions were identified by grouping relevant Expanded Diagnosis Clusters (EDCs) as defined by the Johns Hopkins ACG Case-Mix System. The EDCs used are in parentheses. Conditions that did not reach 2% prevalence were: arthritis, behavior problems, benign prostatic hyperplasia, breast cancer, chronic obstructive pulmonary disorder, congestive heart failure, colorectal cancer, cerebrovascular disease, ischemic heart disease, lung cancer, prostate cancer, psychoses, and renal failure.
Odds ratio from logistic regression adjusting for gender, age, age-squared, income (in quintiles based on median family income by census block group from the 2000 US census), primary facility where member received care, family size(as a categorical variable), gender of the index person, role of the index person (subscriber, spouse or dependent), and cost of the index person in the year before the index date.
Both family groups had less than 2% of persons with this condition
Difference between family members of AODD persons and family members of diabetes persons was significant at p<=0.05, after adjusting for covariables.
