Optimizing Toxicological Screening in Drug Endangered Children

Background:

• Children who enter the foster care system are all too often exposed to illicit drugs in the home. Children from these homes, known as drug endangered children, are not routinely tested for harmful substances. Any short- and long-term physical or developmental problems they may experience as a result of this exposure often go undetected and untreated.
• Children who are placed into protective custody are not always screened by physicians or nurse practitioners. Although drug-endangered children under 18 years of age automatically receive a urine toxicology screen to determine the types and levels of illicit drugs in their systems, this procedure has difficulties and limitations that may affect the quality of the data. Researchers are interested in developing more effective methods of analyzing the presence or absence of illicit environmental drug exposure in children.

Objectives:

- To determine the most effective method of identifying long-term illicit stimulant drug exposure in drug-endangered children.

Eligibility:

- Children under 18 years of age who are being placed into protective custody after having been found in a home where drugs are manufactured, used, or sold.

Design:

• Researchers will gain verbal consent for the procedure for children who are 7 years of age or older. Children younger than 7 years of age will not be required to give verbal consent for sample collection.
• Researchers will collect standard urine samples for toxicological screening. Part of the sample will be sent to the National Institute on Drug Abuse for evaluation; the rest will remain with the local authority.
• In addition to this standard procedure, researchers will collect a hair sample by cutting a small amount of hair from the crown of the head as close to the root as possible (and not pulling any hair out of the child's head).
• Researchers will also use an oral swab to collect a saliva sample from the inside cheek of each child.
• No clinical care will be provided under this protocol....
