Retrospective evaluation of preconception care opportunities in a chain community pharmacy setting

Certain prescription medications should be avoided during pregnancy to reduce the risk of fetal harm. Identification of these medications to minimize exposure may be achieved through the integration of preconception care recommendations into medication therapy management (MTM) services. The primary objective of this study was to identify missed opportunities for pharmacists to provide preconception care support related to medications associated with adverse pregnancy outcomes for reproductive-aged women who received MTM consultations at a regional supermarket pharmacy chain. Secondary objectives examined the concurrent use of prenatal vitamins, folic acid, or hormonal contraception in patients receiving medications associated with adverse pregnancy outcomes.

The study examined all MTM and prescription drug claims submitted by a regional chain of supermarket pharmacies from January 1, 2018 to June 30, 2019, to identify female patients aged 15-45 years who received MTM services. Prescription claims were cross-referenced to determine which of these patients also received medications associated with adverse pregnancy outcomes. To identify patients with long-term use of opioids and nonsteroidal anti-inflammatory drugs, a restriction based on days supplied was then applied.

Of the 2020 female patients who received MTM services and filled at least 1 prescription during the study period, 731 (36.2%) were found to have received at least 1 medication associated with adverse pregnancy outcomes for the minimal days' threshold. Of these, 509 (69.6%) lacked evidence of concurrent prescription contraception, and 74 (10.1%) had a concurrent prescription for folic acid or prenatal vitamins.

The use of medications associated with adverse pregnancy outcomes was widespread in this sample of reproductive-aged women. The findings of this study indicate the need for additional research to investigate the implementation of targeted MTM interventions to build standard workflow processes and facilitate pharmacists' management of this critical clinical issue.
