Background: Baby-Friendly Hospital certification has been one of the national major policies in promoting breastfeeding, which our hospital made active efforts to work in coordination with. The goal of establishing a breastfeeding-friendly hospital was developed by Outpatient Department according to the accreditation indicators to enhance breastfeeding rate and service quality of the hospital. Purposes: It aims to investigate the explicit approaches and achievement made by Outpatient Department for facilitation of the baby-friendly hospital and breastfeeding-friendly environment. Methods: A descriptive method was used to illustrate the explicit approaches for facilitation of the babyfriendly hospital and breastfeeding-friendly environment; meanwhile, a satisfaction survey was conducted to understand the general satisfaction with service quality. Results: It passed the Baby-Friendly Hospital certification in 2014, with a breastfeeding rate of 97.15% during hospitalization. Conclusions/Implications for Practice: Baby-friendly and breastfeeding-friendly environment is an imperative issue, as building a comfortable, supportive and safe environment may prolong the period of breastfeeding. Furthermore, continuous follow-up and improvement based on satisfaction survey may also enhance service quality of the hospital as well as female patients' satisfaction with medical consultation.
