Maternity Services Liaison Committees (MSLCs) are potentially a valuable means of implementing change at local level, and offer midwives the opportunity to influence this change. Not all MSLCs are successful--some are troubled by tensions between interest groups or individuals, or lack of direction. Where a district health authority has more than one provider of maternity services within its area, the MSLC can compare the services offered and advise the purchasing authority on items where a consistent standard should be provided across the district; and on items where a difference in provision provides consumers with choice. Midwives keen to set up teams or group practices in particular ways can use the MSLC as a forum for introducing their plans.
