3. Current Situation vsTarget
Status aimed at the end of the project
< 5% TAT outlier (defects)
To increase the number of tests per day by 36
tests
Increase in the financial benefit between Rs
3960 /day to Rs. 86,400/day
Status at the start of the project
9.1 % TAT outlier (defects)
Test load : 172 tests per day
4. Scope: All biochemistry reports
Out of bounds:
- IP and outsourced tests
- samples billed before 6AM and after 4PM
- National holidays and Sundays
- Timed samples
- Urine and other fluid samples
5. TYPE OF MEASURE
DATA COLLECTION
STRATEGY
OUTLIER
Turn around time from billing to report
verification
- HIS biochemistry data of two weeks
- Sample audit, time and motion study of
two days
TAT more than target time i.e.
4 hours (240 minutes)

12. Improvement strategy:
Phlebotomy:
■ Non value added steps reduced in the sample collection process
■ Takt time analysis done and staff allotted for sample collection during the peak time and back up
provided for sample collection when there are more three patients waiting
■ Two dedicated GDA staff & their back up trained for sample transport and time management
Accession:
■ GDA training for the transport of samples from accession to the biochemistry department
■ Specific time to be allotted for outsource report dispatch
13. Biochemistry department:
■ Pending lists monitored at frequent intervals
■ The unresolved IT issues were compensated to some level by the technical staff
suggestions in the brainstorming session: 1. Manual dilution programming for auto
calculation (manual calculation step was skipped) 2. Manual assignment of the position
and rack ID (helped in the reduction of number of steps in the manual process)
Suggestions that were not implemented-
Two dedicated staff to be provided covering 7AM-5:30PM
Target time of the transport time to be revised to 10mins from 45mins as we have
pneumatic chute system for sample transport
15. Project objective:
Status aimed at the end of the project
< 5%TAT outlier (defects)
To increase the number of tests per
day by 36 tests
Increase in the financial benefit
between Rs 3960 /day to
Rs. 86,400/day
Achievement at the end of the project
4.6 %TAT outlier (defects)
Increased the number of tests per day
by 76 tests
Financial benefit achieved between
Rs 8360 /day to Rs. 1,82,400/day
16. For the sustenance of theTAT
The pending tests list is monitored twice daily at 11 AM and 4 PM by the biochemistry department to
control theTAT of the tests.
Monthly TAT review in the laboratory quality meeting and quarterly TAT review by the hospital quality
department.
Control Phase:
17. Conclusion:
Lean six sigma methodology has helped in the achievement of the following:
increasing productivity without any additional resources;
improving quality by reducing the opportunities for error; and
ensuring the improvements are maintained through systematic and timely monitoring.
The stakeholders have noticed the change and improvement in the turnaround time of biochemistry reports.
Staff feel appreciated and motivated as their suggestions has played a vital role in the success of this project.
Furthermore, this project has served as a model that launched other quality improvement programs in the
hospital
