    OBJECTIVE: It is unclear why nonmental healthcare utilization is greater among those with psychological problems. The authors examined healthcare utilization in HMO patients to determine whether greater utilization in anxiety disorder (AD) patients was explained by anxiety symptoms (increasing sensitivity to physical symptoms) or comorbid illness (causing greater need for services). DESIGN: Patients were randomly selected from the database of a multi-specialty practice and 1,041 completed a survey assessing psychological symptoms, health behaviors, and demographics. Anxiety symptoms were assessed by questionnaire and the presence of an AD was determined from the medical chart. Healthcare encounters and medication use were abstracted from medical charts and HMO claims data. MAIN OUTCOME MEASURES: Healthcare utilization. RESULTS: Both AD and anxiety symptoms predicted utilization, but symptoms were not associated with utilization in a model that also included AD. Comorbid illness was significantly associated with utilization independent of AD and somewhat reduced the strength of the AD-utilization association. The results were replicated in comparison of those with any psychiatric disorder to those without. CONCLUSION: Among those with AD, greater utilization is not explained by anxiety symptoms but is partly explained by greater comorbid illness. Further study is needed to understand excess healthcare utilization among AD patients.
