Introduction: An emerging trend in Academic Medical Centers (AMCs) is to coordinate breastfeeding care, research, and trainee education through 'medical director" positions. Little is known about their duties, supports, and challenges. Objective: To determine the duties and challenges of directors of breastfeeding medicine in AMCs. Methods: A survey was distributed four times over a 3-month period to three listservs with a total of 860 members. Physicians directing breastfeeding programs or services at AMCs were included. Participants were asked about details of their employment, time distribution of the position, their role in education, billing practices, and major hurdles. Results: Thirty-two physicians responded to the survey: 25 from the United States, and seven international. Only 22% of respondents had formal job descriptions and only 31% reported being paid for their breastfeeding work. Most positions were created in the past 10 years (75%), were housed in Departments of Pediatrics (75%), and provided clinical services for breastfeeding in inpatient and outpatient settings. Ninety-one percent of respondents educated trainees and provided oversight of lactation consultants. Major hurdles included difficulties with billing for services, lack of protected time and personal reimbursement, lack of formal structure and job descriptions, and lack of buy-in at the institutional and sometimes governmental levels. Conclusions: Medical Directors of Breastfeeding Services may be increasingly prevalent in AMCs and are engaged in inpatient and outpatient clinical work, trainee education, and lactation consultant oversight. Both financial and structural hurdles were reported by those holding these positions.
