The number used by medical records to uniquely identify a patient's chart; it is different for the same patients at different hospitals.
The number is assigned to a patient by Admitting. This is done once the patient has been seen by Triage in ER or new to the hospital for clinics, testing and various workups. This number remains the patient's chart number for all hospital visits, admissions, tests, etc.
No leading zeros
If your chart number system uses leading zeros, don't enter the leading zeros, start with the first non-zero number.
Pt Doe
Patient is admitted as an unknown "Pt Doe". They are given a new chart number.
- At HSC the chart number for Doe starts with: 300 then 5 digits. Total 8 digits.
- During a patients stay or after discharge from hospital, Health records may find a match to previous chart and they merge 300.....chart number with original chart number.
- Data Collectors use the number that Admitting gave John Doe for his entire stay unless they notice the update of chart number if MR finds it before discharge.
- Data Collectors also enter in the Alias ID collection in the tmp project the alternate MRN, Name or other identifier, eg PHIN.
Data Processing
The Centralized_data_front_end.mdb has queries that make sure that the chart number for each Hospital site is the same for the same patient and make sure the chart number has valid format.
- query PL_SameCHART_Site_Diff_PHIN
- query PL_SamePHIN_Site_Diff_chart
- query PL_Chart_9_Digit
The Data Processor fixes any inconsistencies found from these queries by crosschecking from EPR and adds the alias identifier to the tmp project Alias ID collection.
In addition, the Statistician uses SAS to check key identifiers so they are consistent for same patient including Hosp chart etc.
L_PHI vs L_Log
This field is stored in the L_PHI table in CFE but in the L_Log table in CCMDB.accdb. See L_PHI table for details why.
Template:CCMDB Data Integrity Checks
CCMDB.mdb uses function Validate_chart() to validate the Chart number.
- check that the entry is numerical
- check to ensure that PHIN field and Chart number are not identical.
- no further checks at this time because chart numbers are different at different hospitals
