Morbidity registers |
| Additional information regarding sample selection. | Surveillance system designed to screen for lead poisoning in children (without knowing population toxicity). Recorded blood lead level testing (initial screening and follow-up) ordered in children (younger than 18) following exposure risk factor research (individual identification or screening campaigns), regardless of the result. Includes cases of lead poisoning reported to the ARS/DDASS (blood lead level higher than 100 μg/L) and cases identified during toxicity surveys. |

| Procedures | |
| Data collection method | The prescribing physician must complete a monitoring form and send it to the laboratory with the order for all blood lead level requests for minors. This includes the date and sampling method, as well as the assay result on the form. A copy is forwarded to the inter-regional poison control centre (CAPTV), and the form is returned to the prescribing physician. Forms are recorded on computer in each CAPTV and then digitally transmitted to InVS that constructs the national anonymous database. This system is supplemented by new lead poisoning case reports (first blood lead level higher than100 μg/L) by the ARS to InVS. Duplications are deleted. Data retrieved from the SNSPE are anonymous individual data for individuals younger than 18, when blood samples are taken. |
| Classifications used | - |
| Quality procedure(s) used | Duplicate processing (2 data sources for lead poisoning cases only): section detected automatically by national software application and another section by manual research. Control and recording at CAPTV and InVS application level. Variable data quality: completeness varies according to region and every passing year (improved completeness in the blood lead level number). Some variables are poorly recorded (medical treatments and environmental measures implemented between blood lead levels). |
| Participant monitoring |
Yes |
| Details on monitoring of participants | National recommendations included blood lead level follow-up for poisoning or exposure risk factors.The same monitoring form is completed for successive blood lead levels by the physician to clarify the medical treatment and environmental procedures implemented to avoid exposure. |
