Instances
An “instance” within the MPOG Import Manager framework broadly refers to a source anesthesia system.
The framework supports multiple instances, whether they are multiples of the same type or a combination
of current and legacy systems.
The main impact of having multiple instances on the file pipeline is that each instance from must have a
separate directory. These directories are then assigned to an instance during setup.
Note: Given the possibility of identifier collision, data from different instances cannot be combined. As
such, cases from different instances cannot be assigned to the same MPOG MAS database.
Organizations
Aside from instances, “organizations” are the primary method by which the framework splits apart cases.
For multiple hospitals sharing the same instance, it is often desirable to separate their cases into different
databases. This allows each institution to validate their own cases and prevents users from sister
institutions examining their data.
Each surgical case is assigned an organization by the extract. All organizations detected by the framework
can be assigned a destination MPOG_MAS database. Organizations can be assigned to the same database,
different databases, or no database at all. An organization by default is assigned to no database and
therefore its cases will not leave the MPOG_Import_Manager database.
Variable Mapping
Data elements are commonly stored in anesthesia systems with an assigned variable. These variables
represent a wide variety of things such as blood pressures, medications, notes, staff roles, units of
measure, and so on. Different anesthesia systems use different variables and even the same anesthesia
system can have variables configured differently between hospitals.
In order to provide a standardized lexicon for all these different elements, MPOG provides a data
dictionary called MPOG Concepts. Many of the variables used within your anesthesia system will be
mapped to a MPOG Concept. This mapping helps the MPOG Import Manager framework to decide where
a certain element should go (e.g. intraoperative note vs monitor recording). Furthermore, it helps queries
to written for the central repository without knowing each institution’s specific variables.
Variable Mapping is performed primarily by the Clinical Reviewer using the provided mapping utility. For
more information on variable mapping, refer to the Variable Mapping Guide and your MPOG Clinical
Support.
