3 Outline  Introduction/Background  Overview  Methods  Results  Discussion  Conclusion  Question & Answer

4 Introduction/Background  Approx. 310,000 U.S. children aged 1-5 years have blood lead levels (BLLs) greater than 10 micrograms per deciliter of blood (10 μg/dL), the level at which the CDC recommends public health actions be initiated  In 2006, 1.21% of children tested in U.S. for lead had confirmed elevated blood lead levels (EBLLs)  In 2009… o 2.9% of children tested in WI for lead have EBLLs o 7.0% of children tested in Milwaukee for lead have EBLLs o 8.8% of children tested in the 53204 zip code (Milwaukee) have EBLLs o 9.6% of children tested at Aurora Clarke Square Family Health Center (53204 zip code) have EBBLs

5 Introduction/Background (cont.)  Sources of lead exposure o Lead-based paint and lead-contaminated dust found in deteriorated buildings o Hobbies o Work o Drinking water o Home health remedies  At risk populations o Children under the age of 6 years o Children from all social and economic levels o Children of some racial and ethnic groups  Lead exposure is very costly to treat o $43.4 billion annually  Lead poisoning is entirely preventable

6 Overview  Clinical quality improvement project  Purpose: To determine the effect of including lead screening in a statewide immunization registry on rates of recommended lead screening in an urban community clinic in Milwaukee (53204 zip code)  Cohort study of children age birth to 6 years

7 Overview (cont.)  Problem: Health care providers are missing opportunities to screen children who are at high risk for EBLLs  Hypothesis: Tracking lead screening in a statewide immunization registry will result in increased lead screening compliance among providers in patients age birth to six years  Short-term goal: To increase lead screening compliance in providers treating a pediatric population o Goal: 90% compliance  Long-term goal: To utilize the Wisconsin Immunization Registry (WIR) to track child lead screening rates and thus improve adherence to professional recommendations

8 Methods What did we do?  Conducted a literature search of the adverse health effects of childhood lead exposure/poisoning  Developed a lead screening database of children between 0 and 6 years of age who are seen at the Aurora Clarke Square Family Health Center  Mailed a bilingual (English/Spanish) letter to the parents of children who either need to be screened or who have EBLLs What will we do?  Clinic staff will check the responses received from the letters that were mailed the month before o Who has come in for screening? o Who has a future appointment already set up?  Parents who didn’t respond to the letter will receive a follow-up phone call

9 Methods (cont.)  If the intervention is successful (i.e., if we reach our goal of 90% compliance), we hope to… o Collect baseline lead screening data using chart reviews, and o Enter the lead screening information from chart reviews into the WIR  As children come to the clinic to be immunized, providers can use data from the WIR to determine their need for lead screening

10 Results  Recently began collecting lead data, so the results are still TBD…  However, this lead project is based on a similar study focused on improving childhood immunization rates in Milwaukee  Results from this lead screening project are expected to be similar o Pre-intervention (baseline): 76.9% o Post-intervention: TBD AUWMG = Aurora UW Medical Group ACSFMC = Aurora Clarke Square Family Health Center

11 Results (cont.)  Additional results from childhood immunization study o Process culturally concordant with majority of patient population o Obtained feedback from staff on how process accurately reflects needs of patient o Patients demonstrated more interest in making sure their children were up-to-date with their immunizations  Again, expecting similar results

12 Discussion  Relation of findings to existing literature o Dearth of information exists regarding how to increase lead screening compliance among providers o This project will address gaps in current research by examining an intervention aimed at increasing lead screening compliance in providers treating a pediatric population  Strengths o Cost effective o Utilizes a database that is already being used to track youth immunizations (ease of implementation) o Intervention poses very low risks to patients and is efficient for clinic use  Limitations o Still collecting data, so results are TBD o Lead screening differs from immunization

13 Discussion (cont.)  Implications for public health o Systems approach versus individual approach o Increased compliance to lead screening recommendations and early detection of EBLLs in children could…  Improve future health outcomes for children  Help parents identify and eliminate causes of potential lead exposures in child’s environment  Alert providers to potential health problems a child may face and ensure adequate treatment for their exposure  Increase likelihood that patients, as a whole, will be screened o This research will add data to the limited number of studies that have suggested innovative office practices that can contribute to increased adherence to lead screening guidelines

14 Conclusion  Expect similar results  Recognize differences between immunizations and lead screening o Legal regulations o Expense o Follow-up o Abatement
