Two forms with different purposes

DIAT stands for Denuncia Individual de Accidente del Trabajo and DIEP for Denuncia Individual de Enfermedad Profesional. They are used in Chile’s insurance process under Law 16.744. The choice depends on the occurrence being reported. They are neither interchangeable forms nor a substitute for necessary care. Their purpose is to record the case and allow it to proceed under the corresponding rules.

Reporting is not classification

Notification provides background information; determination of origin belongs to the competent body’s procedure. ISL’s glossary distinguishes these documents from the classification decision, RECA. Filing a DIEP therefore does not mean every reported disease has been definitively recognised as occupational. Nor should the person be required to resolve the technical analysis themselves before reporting a suspicion.

Availability and copies

SUSESO’s compendium establishes availability of forms and provision of copies to the reporting party under the stated terms. Knowing the administering body and its submission channel before an episode occurs is useful. An internal procedure must explain who guides the person and how evidence of notification is retained, preventing the case from remaining only in an informal email.

Required information quality

Data must accurately describe facts, activity, location and circumstances, distinguishing observations from information reported by others. Health information comes through the relevant professional pathway. A narrative aimed at assigning blame may omit important conditions. Versions and additions should be retained traceably, without retrospectively rewriting a statement to fit a desired conclusion.

Coordination example

A person reports an episode during travel connected with their working day. The team can gather the available background and route the appropriate notification while the competent body analyses its origin. In parallel, the enterprise reviews whether there are preventive factors it can address. The example shows two distinct pathways: processing coverage and learning from the conditions surrounding the occurrence.

Relationship with prevention

Accident investigation and disease studies must not stop at filing the form. Their findings may require changes to tasks, controls or collective surveillance. Deadlines and authorised parties must be checked in current Chilean-system instructions. Records contain personal data and must be shared on a limited basis; the need to analyse a problem does not authorise disclosure of clinical information to the entire team.
