Contraceptive Recommendations For Young Women During Cancer Treatment: Examining Contraceptive Knowledge Of Pediatric Oncology Clinicians.

10089 Background: Adolescent and young adult women with cancer have specific reproductive health needs and may seek guidance from oncology clinicians. This study examined oncology clinicians’ reported contraceptive recommendations and contraceptive knowledge. Methods: Oncology clinicians caring for women aged 13-45 completed an online survey. This secondary analysis reports on pediatric clinicians’ contraceptive knowledge by identifying typical failure rates of 10 contraceptives and safety of 4 hormonal contraceptives using case scenarios. Knowledge score was determined by averaging the percent correct on safety and efficacy questions. Results: 518 respondents were included. Most were practicing pediatric oncologists (52.3%) or advanced practice clinicians (42.5%). Participants practiced a mean of 12.5 years and most (64.1%) saw 3-10 reproductive-aged female patients per month. Most (82.0%) reported regularly recommending a woman use contraception during treatment. Over half (53.2%) stated they were comfortable with contraceptive counseling, 69.9% provided contraception in the past year, and 67.1% wanted more information on contraception. Almost half (47.3%) stated they do not discuss pregnancy planning and 233 (45.0%) had cared for at least one pregnant cancer patient. Total knowledge score was 47.4% (95% CI: 45.8, 49.0). Participants identified 61.9% of contraceptives’ safety (95% CI: 60.0, 64.2). 87.1% identified combined oral contraceptives as unsafe after pulmonary embolism. For a nulliparous woman with AML, 30.4% correctly identified the safety of the levonorgestrel intrauterine device (IUD) and 28.9% for the copper IUD. Participants identified 32.6% (95% CI: 31.0, 34.2) of 10 contraceptives’ efficacy. 19.4% correctly identified condoms’ efficacy, 12% for oral contraceptive pills, and 34.8% for depot-medroxyprogesterone acetate. Almost half correctly identified the failure rate of IUDs (46.1%). Most over-estimated the effectiveness of contraceptives. Conclusions: Pediatric oncology clinicians report recommending contraception during cancer treatment, but may lack comprehensive knowledge for counseling their patients.
