Problems related to the CTQs (Significance and Delay of the
results) after Brainstorming and Pareto Charts analysis
are :
1. Multiple result registration

2. Multiple result verification and validation

3. Inappropriate/ Incorrect test request for patients

4. Human Resources (Staff Inadequacy)

Laboratory Supplies (Logistics and Inventory)

5. Error in specimen labelling

The Problem statement:
DEFINE

11% of released laboratory results form January 10-3-
2012 contain more that 8 errors in average per day

45% of patients results and 100% of pre-employment and
visa result from January 10-30, 2012 exceeded
target turn-around-time.

The Goal statement:

1. Reduce the errors from 11% to 8% within 6 months.
2. Reduce delayed patients result from 45% to 30%
within 6 months
3. Reduce delayed pre-employments and visa test
results from 100% to 80%within 6 months.

BREAKTHROUGH improvement actions has been taken
after calculating RPN of each sub-process, Actions
include:

1. Post permanent and trained receptionist
2. All request will be made through IT system (barcoding)
3. Appointment system for pre-emp/Training/
Visa renewal
4. Modify IT system for ICDs/RCOs for physicians in
ordering of test repetitions and tests added after tests
has been ordered
5. Eliminate entry of results in the logbooks
6. Hire porter for transporting the samples
