Excluding pregnancy in individuals prior to initiating contraception is important. The Pregnancy Reasonably Excluded Guide (PREG) uses twelve questions related to a patient’s reproductive history to effectively rule out pregnancy without administering a urine pregnancy screen, saving the patient both time and money. The PREG survey was given at Mayo Clinic in Rochester, MN, from 2015 to 2018 to all patients receiving an Intrauterine Device or Subdermal Implant.

This study examined data from the 2018 collection year to determine if urine screening requests by providers were reduced from the pre-PREG data. It also determined whether urine tests were requested disproportionally for patients by their age range or type of contraceptive procedure. One-hundred sixty-eight women between the ages of 18 and 50 were included, with the majority identifying as white (84%) between the ages of 18 and 31 (54%).

Using a Chi-square analysis, it was found that neither urine test by age (p=0.69) nor urine test by procedure (p=0.98) were significant. Urine tests were not requested more often for certain procedures or by patient age. However, the number of urine screens requested pre-PREG compared to the number requested post-PREG for the year 2018 was significant (P<0.01).

Through implementation of the PREG survey, urine pregnancy testing was drastically reduced and in turn, there were reduced costs to patients and the clinics.
