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

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.

Diagnostic Testing of Vaginitis: Improving the Value of Care.

Vaginitis is one of the most common reasons women access health care in the United States. Despite its prevalence and disruptive impact, it is frequently misdiagnosed and untreated, resulting in unnecessary patient discomfort, follow-up visits, and health care costs. This study presents a costs analysis of diagnostic testing technologies to demonstrate the potential of molecular tests to improve the value of care for women with vaginitis. This study tracks health care spending among women diagnosed with vaginitis and finds that nucleic acid amplification tests (NAATs) are cost-effective for the diagnosis of vaginal symptoms. Women who receive a NAAT on the day of their diagnosis have significantly lower 12-month follow-up costs compared to women who receive a direct probe test or those women who are clinically evaluated without the use of a molecular test. However, despite Food and Drug Administration approval, widely available molecular diagnostics have not been incorporated into clinical guidelines, and many payer policies fail to cover these tests. Greater utilization of NAAT for the diagnosis of vaginitis has the potential to improve the care of women seeking treatment for this prevalent condition and facilitate sexually transmitted infection testing without additional visits.
