Design and methodology in a community, practice-based research network: a study of nurse-midwifery home-birth practice.
OBJECTIVE: To assess the feasibility, probable success, and inherent problems of conducting a multi-site, multi-year cohort study of planned home birth in the USA. DESIGN: A prospective cohort study. SETTING: 14 states across the USA, representing a variety of regions and settings. PARTICIPANTS: 29 home-birth midwifery practices, representing 44 individual midwives in both large and small, solo and group practices. DATA COLLECTION: Birth outcomes for all women initially enrolled in these home-birth practices. KEY CONCLUSION: Multi-site studies of evaluating outcomes in small community-based practices are possible if several requirements are met. IMPLICATIONS FOR PRACTICE: Understudied birth alternatives can be formally researched within a co-operative network of participating practitioners.
