Effective Microscopy Network
National
Intermediate
Peripheral
1. TB smear microscopy services: accessibility vs. maintenance of acceptable level of technical proficiency:
• Laboratories processing less than 500 slides per year need closer attention to assure proficiency
2. Consideration of network’s density:
• One microscopy center per about 100 000 population
3. Three typical levels of organization

Process for EQA Planning and Implementation
1. Make a chart of the laboratory network 2. Conduct inventory of available resources
(actual and projected) • Staffing (# lab personnel at all levels)• Essential equipment such as microscopes• Essential supplies such as slide boxes • Budget (current and potential financial resources
from both government and other partners)
![Page 15: Module PLANNING AND ORGANIZING EXTERNAL QUALITY ASSESSMENT](https://reader035.fdocuments.us/reader035/viewer/2022081520/5681679b550346895ddcdabc/html5/thumbnails/15.jpg)

3. Collect data on laboratory workload• Standardized laboratory reporting form• Data on positivity rates!• RECOMMENDED WORKLOAD per technician:
• At least 10-15 smears /week• No more than 20 smears / day
4. Evaluate status and effectiveness of any current EQA activities; assess reasons for current problems and limitations as well as successes• Collaborate with laboratory and TB supervisors• Document all EQA data

EQA Gradual Implementation
• EQA implementation may include intermediate steps, such as:• Limited panel testing • Countrywide or selective panel testing, followed by
gradual implementation of rechecking• Gradual implementation & expansion of
rechecking after a pilot test, without any panel testing
![Page 19: Module PLANNING AND ORGANIZING EXTERNAL QUALITY ASSESSMENT](https://reader035.fdocuments.us/reader035/viewer/2022081520/5681679b550346895ddcdabc/html5/thumbnails/19.jpg)

How to Start Implementing EQA?
• Involve the authorities• Start simply• Start small• Pilot region• Start with a good communication strategy
• Interest of the programme• Aims and objectives• Confidentiality rules• Acknowledgment• Contacts• Timetable
![Page 20: Module PLANNING AND ORGANIZING EXTERNAL QUALITY ASSESSMENT](https://reader035.fdocuments.us/reader035/viewer/2022081520/5681679b550346895ddcdabc/html5/thumbnails/20.jpg)

Pay Careful Attention to:
• The results• The commentaries, feedback reports…• Comments and recommendations from
participating labs• Best ways of solving problems• Best ways of recommending certain techniques
• Therefore, perfect is not too much!

Documentation
• No program is effective without regular collecting, processing and analysis of data for evidence-based decision making
• Availability of relevant guidelines, standardized R&R forms, datasheets, checklists etc. is of crucial importance
• NRL plays a leading role in preparing documentation and training personnel

Training• All personnel involved in implementation of
EQA activities must receive appropriate information and training
• Clear understanding of EQA principles and practices
• Clear understanding of roles and responsibilities
• Effective communication among different laboratory organizational levels
• Customization workshop

How to Be Successful
EQA requires resources, so make the best use of EQA participation:
• Advocate for good lab performance!• Use data to illustrate the added value to health
outcomes • Thoroughly monitor EQA results• Participate in implementing corrective actions• Consider EQA as
• Continuous education tool• Quality improvement tool

Key Messages
• The progress in EQA implementation requires strengthening of microscopy network
• EQA should be introduced in a gradual, stepwise approach
• All personnel involved in EQA activities should be appropriately trained
• All documentation should be standardized • All EQA data should be thoroughly monitored and
analyzed:• use of data as an illustration of laboratory performance
improved quality and added value to health outcomes
