poe_id

A unique identifier for the given order. poe_id is composed of subject_id and a monotonically increasing integer, poe_seq, in the following format: subject_id-poe_seq.

poe_seq

A monotonically increasing integer which chronologically sorts the POE orders. That is, POE orders can be ordered sequentially by poe_seq.

subject_id

subject_id is a unique identifier which specifies an individual patient. Any rows associated with a single subject_id pertain to the same individual.

hadm_id

hadm_id is an integer identifier which is unique for each patient hospitalization.

ordertime

The date and time at which the provider order was made.

order_type

The type of provider order. One of the following:

• ADT orders
• Blood Bank
• Cardiology
• Consults
• Critical Care
• General Care
• Hemodialysis
• IV therapy
• Lab
• Medications
• Neurology
• Nutrition
• OB
• Radiology
• Respiratory
• TPN

order_subtype

Further detail on the type of order made by the provider. The order_subtype is best interpreted alongside the order_type, e.g. order_type: 'Cardiology' with order_subtype: 'Holter Monitor'.

transaction_type

The action which the provider performed when performing this order. One of the following:

• Change
• Co
• D/C
• H
• New
• T

discontinue_of_poe_id, discontinued_by_poe_id

If this order discontinues a previous order, then discontinue_of_poe_id will link to the previous order which was discontinued. Conversely, if this order was later discontinued by a distinct order, then discontinued_by_poe_id will link to that future order.

order_provider_id

order_provider_id provides an anonymous identifier for the provider who made the order. Provider identifiers follow a consistent pattern: the letter “P”, followed by either three numbers, followed by two letters or two numbers. For example, “P003AB”, “P00102”, “P1248B”, etc. Provider identifiers are randomly generated and do not have any inherent meaning aside from uniquely identifying the same provider across the database.

order_status

Whether the order is still active (‘Active’) or whether it has been inactivated (‘Inactive’).
