Spanish to English Medical Medical: Pharmaceuticals report to include patient in a clinical trial

Dear colleagues,

I am translating a report from a doctor with a recommendation to enrol a schizophrenic patient in a clinical trial. Here's some context:

PROCESO PARA OBTENER EL CONSENTIMIENTO INFORMADO EN ESTA PACIENTE.

P.E.E.A. del problema actual ( motivo de consulta)
Describa el problema actual, evolución cronológica de los síntomas (exacerbaciones o remisiones recientes). Factores que han precipitado, agravado o modificado su enfermedad.

I cannot find what P.E.E.A. stands for (the rest of the text is fine, I'm able to translate it).

Has anyone come across it before?

Many thanks in advance,

Salma
