Objective: To increase blood lead level screening rates in children at 12- and 24-month well visits through provider education and the implementation of a point-of-care (POC) lead screening program in 4 primary care practice offices located in and neighbored by counties with ≥5% prevalence of blood lead levels ≥5 μg/dL. Study design: Baseline data were collected July 2017 to June 2018. All providers received education on screening recommendations and local prevalence of elevated blood lead levels in July 2018. POC testing began June 2019 at 1 of the 4 practice sites. Screening rates were measured by electronic medical record abstraction. Rates were plotted monthly on statistical process control charts during implementation and analyzed using logistic regression under an interrupted time series approach for program evaluation. Results: There was a small but significant increase in screening following provider education (OR 1.04 per month, 95% CI 1.02-1.07). POC testing was associated with a substantial immediate increase (OR 4.17, 95% CI 2.45-7.09) and a substantial continued increase (OR 1.34 per month, 95% CI 1.17-1.54) in screening at the site that implemented POC. Conclusions: POC testing substantially increases blood lead level screening rates at 12- and 24-month well visits and may be beneficial in other primary care settings.
