Computerized surveillance of errors in newborn screening practice.

We describe the use and early results of the Oregon Public Health Laboratory computer to monitor hospital and practitioner compliance with state newborn screening recommendations. The system tracks five major categories of screening practice in which 21 types of errors affecting screening test quality have been identified. Our initial pilot study examined computer generated data for 23,717 specimens submitted by 116 Oregon birthing facilities over a four-month period. Results show that 58.3 per cent of newborn screening specimens were submitted incorrectly according to current state recommendations.

Prevalence of antibodies to Toxoplasma gondii in pregnant women in Oregon.

Sera from 95,929 pregnant women were screened for antibodies to Toxoplasma gondii with the indirect hemagglutination test (IHA) at a 1:64 dilution of the sera. An indirect fluorescent antibody-IgM specific test (IFA-IgM) was used on all sera found to have an IHA titer of greater than or equal to 1:256. From August 1973 to December 1976, 8.1% of pregnant women had IHA titers of greater than or equal to 1:64. In addition, 129 (18.4%) of 700 pregnant women with IHA titers of greater than or equal to 1:256 had IFA-IgM titers of greater than or equal to 1:4. The IHA test was an acceptable test for mass screening of sera from pregnant women. In Oregon, one in every 200 women contracts toxoplasmosis during her pregnancy.
