Newly parents often encounter frustration and apprehension when taking care of newborns due to inexperience and lack of basic care knowledge. Nurses often need to intervene in order for parents to build confidence in taking care of their newborns. The goal of this project was to promote newborns safety when performing rooming-in. The implementation period of this project was from June to December 2008. The parents satisfaction survey score was 42% before the project. According to the 80/20 rule, a total of six resolution plans were implemented after current situation analysis, literature review, and decision-making process. The six resolution plans are: 1. Single access management to the unit; 2. Designed rooming-in sings for rooming-in rooms; 3. Making suitable size bed rail pillows; 4. Increasing staff members with rooming-in mothers; 5. Revision of rooming-in protocol; 6. Revision of rooming-in patient education content. The satisfaction survey score increased to 81% after the implementation of the project. Therefore, the project is effective in improving newborn safety and provides quality care with rooming-in mothers.
