    Abstract:
    OBJECTIVE: In 1991, the Centers for Disease Control and Prevention (CDC) decreased the blood lead level of concern to 10 micrograms/dL (0.48 mumol/L) and recommended universal screening. Because these guidelines continue to provoke controversy, we conducted a study to: 1) estimate the proportion of pediatricians who are members of the American Academy of Pediatrics (AAP) who report screening for elevated blood lead levels; 2) describe their clinical practices regarding screening for elevated blood lead levels; 3) compare attitudes of universal screeners, selective screeners, and nonscreeners; and 4) identify characteristics of pediatricians who universally screen. DESIGN: Confidential, cross-sectional survey of a nationally representative random sample of 1610 pediatricians conducted through the AAP Periodic Survey. SUBJECTS: The study included 1035 responders (64% response rate). Analysis was limited to the 734 pediatricians who provide well-child care (ie, primary-care pediatricians). RESULTS: Fifty-three percent of pediatricians reported screening all their patients aged 9 to 36 months, 39% reported screening some, and 8% reported screening none. Among those who screen, 96% use a blood lead assay. The primary risk factors for which selective screeners screen are: history of pica (94%); living in an older home with recent renovations (92%); living in an older home with peeling paint (93%); and having a sibling who had an elevated blood lead level (88%). Among primary-care pediatricians, 73% agree that blood lead levels > or = 10 micrograms/dL should be considered elevated, and 16% disagree. However, 89% of primary-care pediatricians believe that epidemiologic studies should be performed to determine which communities have high proportions of children with elevated blood lead levels, and 34% of primary-care pediatricians believe that the costs of screening exceed the benefits. CONCLUSIONS: Three years after the Centers for Disease Control and Prevention issued new guidelines for the management of elevated blood lead levels, a slight majority of primary-care pediatricians in the United States who are members of the AAP report that they universally screen their appropriately aged patients, while most of the remaining pediatricians report screening high-risk patients. Many pediatricians may want additional guidance about circumstances under which selective screening should be considered.
