This assignment examines three research studies investigating the impact of various postpartum care interventions on reducing emergency room (ER) visits. The first study utilizes a qualitative approach to understand mothers' experiences and identify key areas of concern during the postpartum period. The second and third studies employ quantitative methods to analyze the effectiveness of providing additional resources and home visit programs in lowering ER visit rates for both mothers and infants. Students are tasked with analyzing each study's design, methodology, findings, strengths, limitations, and implications for improving postpartum care.
