For Hospitals

The California Maternal Data Center (CMDC) is an online tool that generates rapid-cycle performance metrics on maternity care services.  The program is designed to support hospital quality improvement activities and support clinical decision-making around maternity care—using an approach that is low burden, low cost and high value for hospital participants. 

Participating hospitals submit patient discharge data--that they already collect--to the CMDC's secure web-based tool, which can automatically generate a wide range of perinatal performance metrics and patient-level drill-down information.  The rapid-cycle metrics are presented via an interactive and easy-to-use tool-for use by clinicians, managers and administrators.

Hospitals receive:

  • Overall hospital performance measures based on nationally-standardized definitions (Joint Commission and National Quality Forum) 
  • Physician-level statistics-to assess variation within a hospital
  • Benchmarking statistics-to compare your hospital to  regional, statewide, and like-hospital peers
  • The ability to drill-down to the patient level via case review worksheets-to identify quality improvement opportunities-for both clinical quality and data quality

The current set of quality metrics includes:

  • Elective Delivery <39 Weeks (PC-01)
  • Episiotomy Rate
  • OB Trauma (3/4th Laceration)
  • Cesarean Delivery (AHRQ EXP-2)
  • 3rd/4th Degree Laceration-Vaginal Delivery w/ Instrument (AHRQ PSI 18)

  • Cesarean Section--Nulliparous, Term, Singleton, Vertex (PC-02)
  • Cesarean Section--Nulliparous, Term, Singleton, Vertex, Age Adjusted 
  • Cesarean Section--Term, Singleton, Vertex (AHRQ IQI 21)
  • Cesarean Section-Primary (AHRQ IQI 33)

  • Vaginal Birth After Cesarean (VBAC) Rate, Uncomplicated (AHRQ IQI 22)
  • Newborn Bilirubin Screening Prior to Discharge (Leapfrog)*
  • 5 Minute APGAR <7 Among All Deliveries >39 weeks (HEN)
