title: Employer health care plan design and its effect on plan costs.
abstract: This study uses claims data from employers in the Houston Area Health Care Coalition (HAHCC) for 1985 through the first half of 1987 to examine the effect of health care plan attributes on health care costs. Plan attributes affect the site of care and the costs of care. Utilization review clearly was effective in reducing the demand for inpatient services, but that reduction was in large measure matched by increases in care in the outpatient setting. Restrictions on mental health benefits also shifted the site of care. In contrast, neither premium sharing nor the plan's deductible had a significant impact on total plan charges. The study results demonstrate the need to have a comprehensive cost management strategy.
