CCMDB Data cleaner.mdb general information

The data cleaning tool is used by the Data Processor to flag and fix internal inconsistencies in data already submitted by data collectors.

It is an Access program which is also known as the CCMDB Cleaner.mdb program.

The goal is to pull as many of these checks ahead to be done in CCMDB.mdb, but some checks (e.g. those that required TISS data to be available) need to be included in this in office data cleaner.mdb program.

Progress

The Data Cleaning process is a work in progress.

• some checks Julie usually runs have not yet been implemented
• some checks need to be added to the CCMDB.mdb instead of cleaner (do it sooner)

Discussion

• Trish/Pagasa, which check would you like to work on next? Ttenbergen 12:28, 8 December 2009 (CST)

File Location

File name is CCMDB Cleaner.mdb

A master copy of the file is on X:\Data_cleaning\CCMDB Cleaner.mdb

For use, Pagasa copies the file to her C:\ drive. The file can grow to >1GB in size during use so working with it on the network would be too slow.

L_Aux

The table L_Aux contains some calculated values that are exported by TMSX. They are:

• Apache
• Inits - Collector initials - what do you mean collector initial are calculated?--TOstryzniuk 15:39, 8 December 2009 (CST)
• Age - Admit date M_D_Y minus DOB M-D-Y Date of Birth
• LOS -admit date/time & discharge date time.
• Enc
• Index - not calculated
• Serial - serial number during collection. These are calculated.
• HMORT -this is not calculation just "S"urvive or "E"xpired if we know it. Dan wanted us to track hospital outcome but we were not able to get this data easily.
• apspts - APACHE - Acute Physiological points (
• agepts - as per APACHE II Scoring table for age points
• chempts - ?
• totApache (how is this different from "Apache" above?)

Discussion

• How are these calculated, or where are they derived from? Ttenbergen 13:54, 8 December 2009 (CST)

History

• Original SAS data checking/cleaning queries developed by Julie in SAS who obtained input from Trish, data collectors or others where she needed.
• Tina was developing these checks in Access so that others who are not familiar with SAS programming can run or add additional queries into it when needed.
• Pagasa was running the queries and distributing problem ID, by email, fax or phone to data collectors.
• data cleaner.mdb was outputting many false +ve's, and collectors were complaining about the number of items they were being required to check that were not errors.
• The data cleaner.mdb was reviewed by Trish with Pagasa. The problems found and also the original items in the data cleaning.mdb list from Julie is posted below. The list of checks for this program that were are X drive were also transcribed to this list.
