Background
The U.S. Food and Drug Administration (FDA) approved the etonogestrel contraceptive implant for 3 years of use. Evidence suggests that it may be used for up to 5 years for pregnancy prevention, also known as extended use.
Methods
We conducted a national cross-sectional survey among a group of reproductive health clinicians. We developed an online survey using the Consolidated Framework for Implementation Research (CFIR) and distributed it through e-mail listservs and social media groups from May to June 2021. We analyzed results using multivariable logistical regression.
Results
Among the 300 respondents, 195 (65.0%) reported that they always offer extended use, and 50 (16.7%) reported that they sometimes offer extended use. Fifty-five respondents (18.3%) reported that they never offer extended use. After adjusting for age, gender, and clinical setting, we found that complex family planning sub-specialists (adjusted odds ratio [aOR] = 9.32; 95% confidence interval [CI] [1.81, 48.03]) and family medicine physicians (aOR = 4.37, 95% CI [1.58, 12.10]) were significantly more likely to recommend extended use compared with general obstetrics and gynecology (OBGYN) physicians. Clinicians from private practices or health maintenance organizations were significantly less likely to offer extended use than those from academic centers (aOR = 0.19, 95% CI [0.07, 0.51]; aOR = 0.06, 95% CI [0.01, 0.31]). The most common barriers to offering extended use were concerns about pregnancy risk, bleeding, and lack of FDA approval past 3 years. Meanwhile, clinicians identified strong published evidence supporting extended use as a key facilitator for offering it, and they perceived that prior counseling on extended use from a past clinician was a key facilitator for patients to adopt it.
Conclusions
One-third of clinicians in this study did not consistently offer extended use of the contraceptive implant. An opportunity exists to expand access to extended use by focusing on education interventions for clinicians and seeking FDA approval for 5 years of use.
