title: Maternal Intensive Care': a systematic literature review.
abstract: OBJECTIVE
  The objective of this systematic literature review is to review current scientific knowledge on the definition of and the indications for maternal/obstetric intensive care (MIC).
  
  
  METHODS
  We conducted a extensive search in OVID MEDLINE, EMBASE, COCHRANE, CINHAL and CEBAM using the keywords: maternal/obstetric intensive care, subacute care, intermediate care, postacute care, critical care, sub intensive care, progressive patient care, postnatal care, perinatal care, obstetrical nursing, neonatology, pregnancy, maternal mortality/morbidity and pregnancy complication. A total of 180 articles and one guideline were identified and supplemented by a hand search. After title, abstract and full text evaluation, the articles and guideline were subjected to critical appraisal.
  
  
  RESULTS
  Out of 180 potentially relevant articles, we identified 44 eligible articles of which 14 relevant MIC-articles of relatively good quality were selected. The concept 'maternal intensive care' was not found elsewhere, "high-dependency care" and "obstetrical intermediate care" appeared to be best comparable to what is understood as a MIC-service in Belgium. This thorough literature search resulted in a limited amount of scientific literature, with most studies retrospective observational tertiary centre based. No clear definition and admission criteria for maternal intensive care were found.
  
  
  CONCLUSIONS
  This systematic literature review revealed that 1) there is no standard definition of maternal intensive care and 2) that admission criteria to a MIC unit differ widely. Further research is needed to create an evidence-based triage system to help clinicians attribute women to the appropriate level of care and thus stimulate an efficient utilization of maternal/obstetric intensive care services.
