Accuracy at Birth: Improving Birth Certificate Data Beena Kamath, MD, MPH April 27, 2010
Team • Beena Kamath, MD (Study Lead) • Michael Marcotte, MD (Director, Quality Maternity Medicine, Good Samaritan Hospital) • Roni Christopher (QIC) • Edward Donovan, MD (PI-OPQC) • Carolyn Slone, RN (Antepartum) • Jennifer Brodbeck, RN (Labor and Delivery) • Meg James, RN (Manager of Special Care Obstetrics)
Gestational age • Clinical decisions • Research questions • Intervention programs for at risk infants • If the vital statistics are incomplete or inaccurate, risk status, clinical factors, or outcomes will not adequately reflect the population being studied.
Birth certificates From Gould, et al. “Incomplete Birth Certificates: A Risk Marker for Infant Mortality,” 2002.
Measuring Gestational Age • LMP • Problems with recall • Different menstrual cycles • Ultrasound • Compared to references that may not reflect natural variation in population • Measures size, not time (Mustafa, et al., 2001) • Clinical (maturational assessment) • Not accurate below 28 weeks gestation (Donovan, et al., 1999) • Over-estimates age for preterms, thereby underestimating rates of prematurity (Alexander, et al., 1992)
Different results • Methods of estimating GA can lead to disparate results, resulting in systematic biases • Post-term birth rates • Clinical (1.2%) vs. LMP (6.4%) • Wingate, et al., 2007 • Ultrasound (1.1%) vs. LMP (10.1%) • Dietz, et al., 2007 • Rates of prematurity • Clinical (7.9%) vs. LMP (9.9%) • Wingate, et al., 2007 • Ultrasound (7.9%) vs. LMP (8.7%) • Dietz, et al., 2007
Learning from Observations(Following the Gestational Age on the Birth Certificate) Baby born What is going on in OB TV? Delivery log printed from OB TV Gestational age transcribed directly from OB TV to birth certificate worksheet Form completed for State & Federal Gov’t
Problems with OB TV Since OB TV is the source for multiple repositories of information, it makes sense to make sure OB TV is accurate. NICU record of GA Referral from Outside OB Birth certificate record of GA Pregnant mom arrives to GSH Document GA in OB TV with best data OB database record of GA Yes Is ACOG form Available? Perinatal Database record of GA Alternative methods to confirm GA: asking mother herself, calling practice No
Our AIM • To improve the reliability of gestational age recorded in OB TV from 25% to 75% for Good Samaritan Hospital by January 31, 2010 in the population of women with prenatal care who are pregnant with an infant at least 20 weeks gestation
Overall Learning/Challenges Process is complex. Learning OB TV system and people on the ground. Dealing with attitudes about change. Each community practice has different reasons/ disincentives for not completing ACOG form and sending it in correctly.
