Factors related to the use of ambulatory mental health services in three provider plans.
The use of ambulatory mental health (MH) services by adults was studied in three provider plans: Blue Cross (BC), Group Health Cooperative (GHC) and United Healthcare (UHC), an experimental new plan in which a patient's primary care physician managed all of his care. Approximately 8.3% of the enrollees in each plan had some MH use in the 18 months of the study. We studied correlates of MH use (yes/no). Sex was not a significant predictor of MH use. In general, worse health and lower socioeconomic status (SES) were correlated with having at least one MH visit, but better health and higher SES were correlated with a higher quantity of use for those who had some MH use. The three insurance plans did not differ significantly in the proportion of people who had any MH services, but BC users of MH services had 2-3 times more MH visits and higher costs than GHC and UHC users. This suggests that the reliance on primary care providers in UHC and GHC may have changed the nature of MH care as compared to Blue Cross. The effects of income, MH need and symptom sensitivity on MH use were different among the three plans.
