title: Audit of a fetal central monitoring station in a clinical setting.
abstract: OBJECTIVE
  To conduct an audit of the Omniview-SisPorto® central monitoring station (CMS) and determine the effect of the measures undertaken to correct identified problems.
  
  
  METHODS
  All cardiotocograms (CTGs) recorded in randomly selected days of 2006 and 2009, both in the outpatient clinic and labor ward, were reviewed to assess the following parameters: tracing identification, duration, signal quality, signal loss, acquisition method, and time elapsed between tracing-end and birth. A random sample of cases was compared with original paper recordings and 25% of CTGs were re-retrieved for comparison with first retrieval.
  
  
  RESULTS
  Antepartum tracings were identified in 92% of cases. Mean signal quality rose from 96.4% in 2006 to 97.1% in 2009 (p = 0.009). Mean signal loss fell from 7.4% to 5.8% (p = 0.012). Intrapartum CTGs were identified in 44% of cases in 2006 and in 69% in 2009 (p < 0.001). Mean interval between tracing-end and birth decreased from 12.0 to 8.4 min (p < 0.001). Coincidence of variables in tracings retrieved twice increased between 2006 and 2009. All retrieved tracings matched the original paper recordings. Several technical problems identified in 2006 were not found in 2009.
  
  
  CONCLUSIONS
  The Omniview-SisPorto® system showed reliable recording, storage, and retrieval of CTGs. Auditing of fetal CMSs allows improvement of their performance and use.
