Breastfeeding has been shown to dramatically improve health outcomes for both infants and mothers. Despite recommendations by almost all world and national health organizations to breastfeed exclusively for 6 months and to continue breastfeeding for one year, this goal is not met by the majority of women in the United States for multiple reasons. Health professionals, including physicians and nurses, can play a major role in educating and influencing mothers about breastfeeding, especially for women with comorbidities, taking medications, or undergoing medical procedures. An online survey was created to evaluate healthcare professionals' breastfeeding knowledge and opinions at a large hospital in Phoenix, Arizona using QuestionPro software. This survey was distributed for three weeks to the nursing and physician departments at the hospital in primarily the obstetric and post partum units. Of the seventy-nine individuals who completed the survey, the respondents were primarily female obstetric nurses. Respondents recognized the benefits of breastfeeding for both mother and infant, believed health professionals can influence the decision to breastfeed, and found a lack of support was the number one reason women discontinue breastfeeding. Despite this information, it is apparent from this survey, and similar studies in the past, that there are significant gaps in knowledge especially when it comes to contraindications to breastfeeding, medications used while breastfeeding, fluid intake during breastfeeding, and foods that can be consumed while breastfeeding. Additionally, the majority of the nurses who completed this survey did not believe their schooling adequately trained them in breastfeeding education and hands-on practice. This information could be used in future studies to guide breastfeeding education for nurses, physicians, and other health care professionals at the stated hospital and other facilities across the nation.
