There Should not be an observation as fatal for AE outcome under Adverse Events form, hence as part of release 1.5.1 we are removing the Concept form AE outcome concept set, inorder to remove it we want the implementers to cross check if there is any such observation.
You can use the below script to check which treatments are having this
SELECT
pi.identifier,
ppa.value_reference,
cn.name,
o.value_datetime,
o.concept_id,
o.value_coded
FROM episode_encounter ee
JOIN obs o ON o.encounter_id = ee.encounter_id
AND o.concept_id = 1445
AND o.value_coded = 473
JOIN concept_name cn ON cn.concept_id = o.concept_id
AND cn.concept_name_type = 'FULLY_SPECIFIED'
JOIN episode_patient_program epp ON epp.episode_id = ee.episode_id
JOIN patient_program pp ON pp.patient_program_id = epp.patient_program_id
JOIN patient_program_attribute ppa ON ppa.patient_program_id = epp.patient_program_id
AND ppa.voided = 0
JOIN patient_identifier pi ON pi.patient_id = pp.patient_id
JOIN person p ON p.person_id = pi.patient_id;
