Background and objectives: US children experience lead poisoning, which has detrimental health effects and significant individual and societal costs. This study aimed to describe the sociodemographic and hospitalization characteristics of children hospitalized for lead poisoning and assess the proportion of inpatients who received blood lead testing and appropriate follow-up testing before hospitalization.
Methods: 2015-2021 hospital discharge data were linked to lead surveillance data for Pennsylvania children aged 0 to 5 years. Demographics, hospitalization characteristics, and lead testing data from children with a primary diagnosis code of lead poisoning were used. The number of hospitalizations, associated hospital length of stay and charges, and the proportion of inpatients who received lead testing and follow-up testing after identification of high blood lead levels before hospitalization were analyzed by selected characteristics.
Results: During the study period, there were 93 children hospitalized for lead poisoning, incurring 443 inpatient days and approximately 6 million dollars in inpatient charges. Of these inpatients, 69.9% were males, 36.6% were non-Hispanic Black, 67.7% were aged 0 to 2 years, 14% had repeated admissions, and 88.2% of admissions were paid by Medicaid. In addition, 20.4% did not have lead testing, and 34.4% had appropriate follow-up testing before hospitalization. Non-Hispanic whites and children with developmental, behavioral, and emotional disorders had relatively low proportions of having appropriate follow-up testing.
Conclusions: Severe childhood lead poisoning is a significant health and economic burden, especially among children with Medicaid. Further improvements in blood lead testing and follow-up testing can help prevent childhood lead poisoning.
