# Inventory

This data model is for tracking surgical supplies (e.g., scalpels, bandages) between systems.

Inventory workflows are common for connecting to inpatient EHR systems with robust interfacing capabilities and surgical specialty modules. Supplies are often used in areas that function similarly to surgery (e.g., invasive cardiology, angiography). 

You can exchange inventory data with inventory management systems, the EHR system, or other system responsible for consuming supplies.

This data model has event types that allow you to:

- send administrative updates; or 
- document supply depletions.

> **EHR support for Inventory**
>
> Enterprise Resource Planner (ERP) systems typically support `Update` data via an HL7v2 MFN format or proprietary API. `Deplete` data is most commonly supported via an HL7v2 OMS or DFT format or proprietary API.

> **Inventory vs. Financial data model**
>
> Both data models contain administrative details with financial impact. 
>
> - `Inventory` focuses specifically on item usage and costs. 
> - `Financial` contains patient charges, which can include inventory-related charges.
