How Cost Savings Can Be Realized

Standardizing preterm labor evaluations reduces unnecessary admissions and results in significant cost savings.1 Data shows that the introduction of fFN to triage reduces lengths of stay. In a recent example, introduction of fFN testing reduced the average hospital stay from 5.2 days to 0.6 days.2

Case Study: Brigham and Women’s Hospital3

At the Brigham and Women’s Hospital in Boston, MA, the introduction of fFN to triage led to a decrease in hospital days, resulting in an annual savings of $1 million.3

Case Study: Mayo Clinic1

The Mayo Clinic in Rochester, MN, lowered the rate of hospital admissions for women who did not go into preterm labor by 56%. They believe that a standardized protocol measuring cervical length and fetal fibronectin reduces hospital admissions and expenses for preterm labor and birth.

Case Study: St. Joseph’s Hospital4

At St. Joseph’s Hospital in Phoenix, AZ, the total cost for each unnecessary preterm labor admission was $20,000, totaling nearly $1 million annually. They are taking advantage of the potential that currently available diagnostics could significantly lower this cost without jeopardizing outcomes.
