The second model adds other health factors, financial resources, and social support. All three types of household disability remain statistically significant predictors. Financial resources and social support access, though, are unrelated to service use. The final model investigates interaction terms between the three disability types and the age and cognition of each partner. Disability alone is no longer a significant predictor of in-home medical service use.
Older men remain statistically more likely to move the household into in-home medical service use.
In contrast, households in which wives are older and which have access to more children are less likely to use in-home medical service. Of the cross products, only the interactions between wife's disability and husband's cognition are significant predictors of in-home medical service use. The odds of in-home medical service use among households in which husbands, or both wives and husbands, are disabled are significantly higher when wives are of advanced age or are cognitively impaired. When all other variables had been included, disability alone was not a significant correlate of in-home medical service use. Older couples, even when disabled, seem able to manage without formal in-home medical care.
