- Abstract : Introduction: The 2003–2005 Confidential Enquiry into Maternal and Child Health (CEMACH) encouraged 'the routine use of a national obstetric early warning chart'. Our trust trialled the CEMACH example of a MEOWS observation chart (Modified Early Obstetric Warning System). Observations exceeding a threshold level fall into colour-coded trigger zones. Two observations in the yellow zone or one in the red zone triggers an obstetric/anaesthetic review. The authors wanted to assess the impact this chart had on the medical workforce with trigger thresholds at the levels suggested by the CEMACH MEOWS. There is little or no validation evident in the literature of MEOWS nor the threshold levels suggested.

Conclusion: Until validation occurs, it is difficult to determine whether this triggering rate is true or due to inappropriate thresholds. This triggering rate requires a frequent response, which has a significant impact on workforce. Further work on sensitivity and specificity of MEOWS is required before questions regarding its benefit can be answered. … (more)
