Add alcohol consumption fields

[arschat]

For which schema is a change/update being suggested?

I would like to request an update to the medical_history.json schema. I would like to add 4 new fields and deprecate a previous free-text field, to harmonise the alcohol consumption values.

What should the change/update be?

This update constitutes a major change to the schema(s) it affects.

What new field(s) need to be changed/added?

• Field name: alcohol_status

  • Field description: Does the donor have drink/ drank/ never drank alcohol?
  • Field type: string
  • Required: no
  • CV or enum: active; former; never

• Field name: alcohol_type

  • Field description: Types of alcoholic beverages the donor consumed.
  • Field type: array of strings
  • Required: no
  • CV or enum: beer; liquor; wine

• Field name: alcohol_units

  • Field description: Alcohol consumption of donor in alcohol units per week (strength (ABV) x volume (ml) ÷ 1,000).
  • Field type: number
  • Required: no
  • CV or enum: 2.5; 15.2; 23

• Field name: alcohol_usage_duration

  • Field description: Number of years the donor has used any alcohol.
  • Field type: integer
  • Required: no
  • example: 5

• Field name: alcohol_history

  • deprecate previous free-text field

Why is the change requested?

Many bionetworks (5 as of today) have requested information on alcohol consumption in a more harmonised way than free-text which was previously in the schema.
