Project Title : Oracle Health Care (Nov 2011 - Dec 2011 )
Project : In US Hospitals Surgical costs are increasing faster
Description than reimbursement. Organizations are faced with
greater challenges to manage their surgical throughput
and resource allocation effectively without
sacrificing the quality of patient care. Meeting these
challenges has made Analytics an organizational
priority.
OR transactional systems have basic reporting
capabilities that are limited to data stored in their
systems. Today's OR decision makers need real time
access to reports consolidating the OR transactional
data with other hospital system data e.g. HIS,
clinical, financial and materials management.
Enterprise analytics is used to improve OR scheduling
and resource allocation, reduce OR related adverse
events and infection rates, improve pay for
performance and provide business intelligence
associated with Operating Rom behavior such as
surgical case/procedure trends, volume, etc.
This project covers the ETL design process that need
to be implemented in the proposed Oracle ORA System.
It covers the approaches required to load the data and
other issues ETL should handle during the data
loading.
The ETL process involves extracting data from the
Oracle ORA transactional database, performing
transformation of certain data items and finally
populating the warehouse.
The ETL process has a standard and extensible approach
to support more reports also support loading of data
from various sources.
