To
explain how data is populated in the data warehouse, I read an article "Examining the use of Business
Intelligence in Healthcare Management" by Troy Felix, Mansi Saha, Kakoli,
Dyni Brookshire and Victoria Duncan. This article compares four different
companies (Cleveland Clinic, NaphCare incorporated, Harris County Hospital
District & The Christus Healthcare System) and defines business
intelligence as the architecture, tools, databases, applications and methodologies
that help a business to acquire a better understanding of its operations. As I
explained in my previous blog, Cleveland clinic gathers its intelligence from
databases of its various departments because each one of those departments has
its own self-contained processes, systems and databases and so they had to
bridge the gap between these different silos. Cleveland clinic populates its
data warehouse with the aid of softwares like WebSphere (WebSphere Application
Server), LDAP directory, IBM DB2 database and other configuration tools.
Also,
for their data mining and data-warehousing Cleveland clinic believes
that visualization allows the clinic to identify similarities and trends among
large groups of data. As such, they use a multidimensional visual data system
to analyze their different data sources some of which are clinical, phenotypic,
and demographic etc. To gather reports NaphCare uses Tech Care software
which helps increase the efficiency and accountability of the healthcare program.
This software also serves as a check for the company to follow the highest
standard of care. At Cleveland clinic, because of accurate reports
and data warehousing; a physician can now extract the ordering information
from patients for whom a blood hemoglobin level was ordered through
the organizations data system. With Christus Health, the technical aspects
of data warehousing has led to better allocation of resources and
better care delivery.
