OBJECTIVE: The objective of the study was to examine Michigan obstetric providers’ provision of obstetric care and the impact of malpractice concerns on  their practice decisions. 

STUDY DESIGN: Data were obtained from 899 Michigan obstetrician-gynecologists, family physicians, and nurse-midwives via a statewide survey. Statistical tests were conducted to examine differences in obstetric care provision and the influence of various factors across specialties. 

RESULTS: Among providers currently practicing obstetrics, 18.3%, 18.7%, and 11.9% of obstetrician-gynecologists, family physicians, and nurse-midwives, respectively,  planned to discontinue delivering babies in the next 5 years, and 35.5%, 24.5%, and 12.6%, respectively, planned to reduce their provision of high-risk obstetric care. "Risk of malpractice litigation" was 1 of the most cited factors affecting  providers’ decision to include obstetrics in their practice. 

CONCLUSION: Litigation risk appears to be an important factor influencing Michigan obstetric  providers’ decisions about provision of care. Its implications for obstetric care supply and patients’ access to care warrants further research.
