Measuring psychiatric utilization: the rubber yardstick

Area of Science:

• Healthcare Management
• Mental Health Services Research
• Health Economics

Background:

• Traditional methods for assessing mental health benefit utilization, such as the percentage of total benefits paid, are often imprecise.
• Fluctuations in non-psychiatric service payments can disproportionately affect the apparent utilization rates of psychiatric services.

Purpose of the Study:

• To propose a more accurate metric for measuring psychiatric service utilization.
• To compare psychiatric utilization across different healthcare plans using a refined methodology.

Main Methods:

• The study critiques the 'percent of total benefits paid' metric for psychiatric care.
• It advocates for calculating covered charges attributable to psychiatric care per person covered under a health plan.
• Analysis includes data from the Civilian Health and Medical Program of the Uniformed Services (CHAMPUS).

Main Results:

• The 'percent of total benefits paid' method can be misleading due to the large proportion of non-psychiatric costs.
• The preferred method, 'covered charges per person,' provides a more precise measure of actual psychiatric service utilization.
• When calculated correctly, psychiatric utilization under CHAMPUS is demonstrated to be significantly lower than under many other plans.

Conclusions:

• Accurate measurement of psychiatric service utilization is crucial for effective healthcare management and policy.
• The per-person charge method offers a superior approach to understanding mental health benefit utilization.
• Findings suggest a need to re-evaluate how psychiatric care access and use are reported across different healthcare systems.
