The unintended pregnancy rate with the use of Long Acting Reversible Contraception (LARC) is superior to that with use of non-LARC . Women are delaying childbearing in pursuit of other interests. Health care reform with expansion of Medicaid and social media use have been favorable towards LARC uptake. OBGYN residents have four years to acquire skills to become adept in the provision of longitudinal care tailored to the contraception needs of women across their reproductive cycle. 521 respondents from a pool of 1505 residents (34.6%) in 68 programs, from 38 states All four postgraduate years and US regions were represented. The majority (99%) had received didactic or simulation training on LARC placement, 98% had already placed a LARC, 97.4% were moderately to extremely confident in their counselling ability 99% would recommend a LARC regardless of year of training, geographical region or religious affiliation of program. Knowledge based questions were correct 77%-98% of the time, with improvement based on year of training. 53% reported using a mobile device app to aid in knowledge and practice. The hormonal IUD was preferred for placement among multiparas and those with chronic medical illnesses. The availability of low cost immediate post partum placement has increased uptake in this patient cohort. The Etonogestrel subdermal implant was preferred for placement among nulliparous patients OBJECTIVES To evaluate the knowledge, perception and practices towards LARC among current Obstetrics and Gynecology residents in the United States. To compare the attitudes towards LARC of current residents to those in previous studies. Factors facilitating LARC uptake were Barriers affecting LARC uptake were Increased public awareness Lack of patient insurance Increased coverage for immediate postpartum/pregnancy loss placement Negative perceptions and prior experiences among patients Medicaid expansion with provision of low cost/no cost IUD Lack of provider reimbursement Increased resident exposure by faculty Institutional or state restriction affecting LARC provision Dedicated family planning rotations/Ryan training programs DESIGN AND METHODS Web based cross sectional study involving residents enrolled in ACGME accredited Obstetrics and Gynecology programs across the USA. LARC included the Levonorgestrel IUD (LNG-IUD) (Mirena, Liletta, Kyleena, Skyla), the Copper T 380 IUD, and the Etonogestrel subdermal implant. Data was collected using SurveyMonkey. Results were analyzed using descriptive statistics and SPSS 24 for statistical tests. CONCLUSIONS Current US OBGYN residents are more confident in their knowledge and skills in LARC placement compared with residents from previous studies1,2. Residents attribute their experience to the increased availability of low or no cost IUDs, immediate postpartum placement of LARC, increased public awareness and increased faculty support3,4. Technological advances such as apps are important educational tools that can increase resident comfort and confidence in providing evidenced based care.  Westhoff C, Marks F, Rosenfield A.
