Optimizing Vaginitis Diagnosis to Reduce Health Care Costs in Nonpregnant Women Utilizing Molecular Diagnostics

Abstract

Vaginitis is a common condition that affects women of reproductive age. Early and accurate diagnosis and identification of the causative agents (ie, fungi, protozoa, bacterial species, etc.) help to avoid incorrect treatment and subsequent visits that add costs and therapies, which increase overall health care utilization. A prior study by Kong et al presented a cost analysis demonstrating that women who received a nucleic acid amplification test (NAAT) on the day of their vaginitis diagnosis had significantly lower 12-month follow-up costs than women who received a direct probe (DP) test or women who received clinical evaluation without the use of a molecular test. This prior analysis included pregnant women, which may have influenced the findings. The objective of this analysis is to determine whether the exclusion of pregnant women from the study cohort impacts the previously observed NAAT cost-savings results. The current analysis adds evidence that nonpregnant women diagnosed with NAAT at their initial visit have significantly lower 12-month overall health care costs than women evaluated through DP or other clinical methods.
