Belgium, with its pluralistic health care system, has many small-sized maternity units staffed almost exclusively with obstetricians. The maternal and perinatal mortality and morbidity rates are still higher than in some of the neighboring countries. The new regulations with regard to the accreditation of maternity units might improve the figures. Other measures must be taken, however, to ensure that only low-risk patients are taken into small maternity units and that all high-risk cases and all those developing complications are cared for in large, well-equipped and well-staffed hospitals. Some form of peer review would also be beneficial.
