Enhancing Lead Testing and Prevention Strategies in Washington D.C.
In 2023, the Washington D.C. Childhood Lead Poisoning Prevention Program (D.C. CLPPP) faced a significant challenge: a decline in blood lead testing rates, particularly among high-risk populations such as children from low-income households, those under six years old, and immigrant and refugee children. Recognizing the urgent need for enhanced public awareness and access to testing, the D.C. CLPPP implemented a series of strategic interventions aimed at reversing this trend.
To improve lead testing rates, the D.C. CLPPP developed an internal lead testing dashboard using Tableau 2022.1, providing stakeholders with real-time access to critical data for informed decision-making. Strategic partnerships with organizations like DC Water and DC WIC facilitated targeted outreach campaigns, including the "Twice by 2" initiative, which used social media, radio, and transportation advertising to reach specific zip codes. Additional engagement strategies, such as back-to-school notifications and birthday card reminders, were also introduced to encourage compliance with testing protocols.
These efforts collectively led to a rebound in lead testing across the district. The total number of children tested rose in 2024 from 2023, showcasing a 1.5% increase in children tested. Correspondingly, the overall testing rate -number of children living in DC compared to the number of children tested- increased 1.0 percentage point going from 23.7% in 2023 to 24.7% in 2024. This amounted to a 4.2% relative increase between 2023 to 2024 compared to the relative decline of 13.5% seen between 2022 and 2023. These efforts showcase that DC CLPPP's public health innovations and outreach activities have made an active impact on childhood lead testing.
The success of these initiatives demonstrates the effectiveness of a data-driven approach combined with community engagement. D.C. CLPPP's plan emphasized promoting initial and routine lead testing, ensuring follow-up tests, and collaborating with childcare organizations to enhance outreach to younger populations. This strategy not only improved lead testing rates but also established a foundation for sustained public health efforts in Washington D.C.
