Understanding barriers to uptake of 17 alpha-hydroxyprogesterone caproate (17-OHP) in women with history of preterm birth

Abstract

Background: Premature birth is responsible for approximately 38% of infant deaths as well as a host of complications, including abnormal lung development, infection, and long-term disabilities. For women with a history of spontaneous preterm birth in a singleton pregnancy, use of 17 alpha-hydroxyprogesterone caproate (17-OHP) can reduce the risk of a recurrent preterm birth by up to 42%. However, less than half of eligible women currently receive 17-OHP.

Objectives: The purpose of this study was to understand the barriers to access and acceptability of 17-OHP use from the patient perspective.

Study design: A qualitative study was conducted of women with a history of a prior spontaneous, singleton preterm birth who were eligible for 17-OHP during a subsequent singleton pregnancy. Researchers recruited 118 eligible women during the Spring and Summer of 2018 from a safety-net hospital in Denver, CO, USA, a hospital that provides healthcare for individuals regardless of their insurance status or ability to pay. Responses from 35 participants were analyzed, looking at themes surrounding knowledge of and counseling received regarding 17-OHP, hesitations, and barriers toward receiving the treatment.

Results: Among respondents (34.0% response rate), the mean age was 31.5 years and mean gestational age at delivery was 32.1 weeks. Major themes from interviews included reasons that encouraged women to use 17-OHP, such as the desire to do anything for the health of their baby and reasons that women felt discouraged from using 17-OHP, including unknown complications and lack of information. Other barriers to this treatment method included the time commitment, specifically the length of clinic appointments and concerns about the safety of the 17-OHP injection.

Conclusions: One of the strongest reasons for women choosing to use 17-OHP was a desire to do anything possible to support their babies. Somewhat surprisingly, there was not a significant relationship with the participants between gestational age of prior preterm deliveries and subsequent use of 17-OHP. There were two important reasons women cited most frequently for choosing not to use 17-OHP. One was feeling that they lacked information or knowledge about 17-OHP to make an informed decision, which is crucial because the study also showed that all eligible women are not being appropriately counseled on the option of 17-OHP. In terms of time commitment, it was the length of individual appointments, rather than frequency that was a barrier to receiving weekly injections.
