Subject Title: Patient Case Costing
Procedure
Original Date: May 24, 2004
Revision Date:
Annual Review Date: May 31, 2013
Purpose:
To describe the laboratory procedure to set up workload in the Laboratory Information
System for Patient Case Costing
Procedures:
1. Test IDs are created in the LIS by Pathology and Laboratory Medicine and
Microbiology LIS staff.
2. Each test ID requires corresponding entries in the following by LIS staff:

LIS Test Setup Checklist. Refer to LIS procedure manual for detail (Softlab
New Test Setup Checklist).

LIS Workload Checklist to meet MIS and TSI (old name for Case Costing
system) requirements. Refer to LIS procedure manual for detail.

TSI Code List including the following required information:
a. Cost centre. Use the cost centre number where test is done. Check with
managers or supervisors for accurate cost centre numbers.
b. TSI Code
c. Test Name
d. Link Codes
e. Labor RVU. Use MIS workload unit assigned for the test. If MIS unit is
not available, estimate number of minutes required to perform each test
(only hands on time should be used). This information is obtained from
managers or supervisors. If test is referred out to another institution, use
the MIS units for referred out as the labor RVU.
f. Supplies RVU. Estimate reagents and supplies cost per test and remove $
sign from the value. This information is obtained from managers or
supervisors. If test is referred out to another institution, use the charge
levied by the external institution as the supplies RVU.

Procedure
g. Activity definition.
3. When new tests are created, LIS staff should forward updated Case Costing Excel
file to Case Costing (Form TSI Form2_MoProdInfo).
4. LIS staff should test workload setup system at least annually in the LIS test
system to ensure data quality and integrity.
5. Capture of workload
Workload in the LIS is set to auto capture on a nightly basis. Scheduled monthly
reports are run on the 7th of the month for the previous calendar month, allotting
time for resulting of longer turn around time tests. For detail procedure, refer to
LIS Workload Reports Procedures
6. Capture of workload for Case Costing on a monthly basis:
For Case Costing, a patient specific workload file in the form of a zipped file is
provided to Case Costing on a monthly basis. The extraction of data is performed
by using a Microsoft Access program developed by AMS based on MSH
specifications. For detail procedure, refer to TSI Monthly Extract Procedure
7. Case Costing imports the data from Pathology and Laboratory Medicine and
Microbiology and Finance’s GL into the Case Costing system. Based on the
RVUs provided by the laboratory, the system computes the actual case costing for
each patient. Other hospital department systems are also interfaced with the Case
Costing system using the same methodology outlined for the laboratories. See TSI
Extract (Access Application)-Patient Costing Workload Process.
