| The '''data cleaning tool''' is used by the [[Data Processor]] to flag and fix internal inconsistencies in data already submitted by [[data collector]]s.
| | Legacy only, this is done with [[Centralized data front end.accdb]] now. |
|
| |
|
| It is an Access program which is also known as the '''CCMDB Cleaner.mdb''' program.
| | [[Category:Legacy Data Processing]] |
| | |
| 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)

| * Trish/Pagasa, which check would you like to work on next? [[User:Ttenbergen|Ttenbergen]] 12:28, 8 December 2009 (CST) [[User:Ttenbergen|Ttenbergen]] 10:19, 2012 September 11 (CDT)

| == 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.
| |
| | |
| The CCMDB_Cleaner.mdb pulls and pushes data from various file locations. The addresses are stored in the table '''x_defaults'''.
| |
| | |
| == L_Aux ==
| |
| The table L_Aux contains some calculated values that are exported by TMSX. They are:
| |
| * '''Apache''' -
| |
| ** Not sure where you are getting your data from for this. The registry screen maybe? Ed scores APACHE in the APACHE II file for each patient and also records the total Apache score into the Registry file for each patient.
| |
| *** The first (APACHE) arrives with the registry file, the second with the apa file. Are the two identical? [[User:Ttenbergen|Ttenbergen]] 10:34, 9 December 2009 (CST)
| |
| ****yes they are suppose to be.--[[User:TOstryzniuk|TOstryzniuk]] 12:13, 9 December 2009 (CST)
| |
| | |
| * '''Inits''' - Patient initials generated from patient name. Used for error listings to keep info more private.
| |
| | |
| *'''[[Age]]''' - Admit date M_D_Y '''minus''' DOB M-D-Y = [[Date of Birth]]
| |
| | |
| * [[LOS]] -length of stay. discharge D_M_Y_time minus admit D_M_Y_time
| |
| | |
| * '''Enc''' - Encounter - currently not used. A sorting utility program that use to tally the number of encounter to the database. Sorting was done using, FN, LN, DOB and PHIN? We had suspending using it when we found many data errors in DOB or name spelling, PHIN. Since we have worked on fixing this problem we have not continue to use it.
| |
| **see: [[Identification Numbers]]
| |
| | |
| * '''Index''' - not calculated. This was a old file system number we used. See: [[Identification Numbers]]
| |
| | |
| * '''Serial''' - serial numbers are collection site organization number used during collection. These are not calculated. No sure what you mean? See: [[Identification Numbers]]
| |
| | |
| * '''HMORT'''-Hospital Mortality-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 see [[APACHE Scoring table]]. (For added detail Ed's program showed APS score using [[APACHE Scoring table]] items 1-11 and GCS score separately. APS = APS + GSW (which includes all physiological variables including GCS).
| |
| | |
| * '''agepts''' -Age Points-as per [[APACHE_Scoring_table#Age_Points | Age Points]]
| |
| | |
| * '''chempts''' - Chronic Health Points as per [[APACHE Scoring table#Chronic Health Diagnosis for APACHE II | Chronic Health Points]] (0 , 2 or 5)
| |
| | |
| * '''totApache''' total Apache Score -(how is this different from "Apache" above?)- see story under Apache above.
| |
| ** TotApache = APS + GCS + chempts + agepts
| |
| | |
| == 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.
