title: Design and methodology in a community, practice-based research network: a study of nurse-midwifery home-birth practice.
abstract: 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.
  
  
  METHODS
  A prospective cohort study.
  
  
  METHODS
  14 states across the USA, representing a variety of regions and settings.
  
  
  METHODS
  29 home-birth midwifery practices, representing 44 individual midwives in both large and small, solo and group practices.
  
  
  METHODS
  Birth outcomes for all women initially enrolled in these home-birth practices.
  
  
  CONCLUSIONS
  Multi-site studies of evaluating outcomes in small community-based practices are possible if several requirements are met.
  
  
  CONCLUSIONS
  Understudied birth alternatives can be formally researched within a co-operative network of participating practitioners.
