EWC has prepared an updated country package for you to get started with AEM5 This package contains: Your UNAIDS submission from 2020 (Spectrum PJNZ submitted & the AEM415 file or combiner extracted from it) An updated version of your 2020 submission Spectrum file: <CountryName> AEM-2020 Draft ND1.PJNZ Adult natural history, ART allocation & ART infectivity reduction updated An import of your projections into the AEM5 baseline: <CountryName> AEM-2020 Draft ND1.xlsm Aligned populations and ART with what was in Spectrum Spectrum-AEM comparisons for both: Spectrum-AEM compare <CountryName> 2020.xlsm Spectrum-AEM compare <CountryName> Draft ND1.xlsm A comparison of the draft AEM5 with your 2020 submission <CountryName> compare 2020 vs ND1.xlsm The country file package provided as a starting point
1. Download the new version 6.04 from the Avenir Health web site at: https://avenirhealth.org/software -spectrum.php Spectrum Software for 2021 2.

Compare your 2020 Spectrum submission with the Draft ND1 Spectrum file. Some things will have changed to use AEM5: New defaults for adult natural history have been applied ART infectivity reduction has been changed to 0.8 instead of 0.7 New default value for ART allocation is being used Update your Spectrum file for AEM5 Follow the steps in the 05 Basic steps to update Spectrum.pptx video to update your Draft ND1 file with: New pediatric parameters New program data for PMTCT, ART (adult and child) Information on ANC testing, knowledge of status, viral suppression, and ART by age
Make related changes in your AEM5 file Update the ART coverage to agree with Spectrum
Make related changes in your AEM5 file NOTE: Spectrum use 999 for Treat all , AEM uses 1000 Make sure ART eligibility CD4 threshold agrees Check infectivity reductions Check ART allocation weight 12 Spectrum page in AEM Advanced options-> Adult transition parameters -> HIV mortality with HIV Advanced options-> Allocation method for new ART patients
Update any size estimates, behavioral inputs or prevalence inputs in your AEM5 file
1 4 Update your AEM fit 1. Run AEM with Add-ins- >AEM->Run AEM menu item 2. Adjust transmission parameters as needed 3. Click Save and Exit in AEM 4. Click Get AEM Results in the AEM menu 5. Save your AEM file in Excel 5. Save file in Excel 2 3
Import your AEM to Spectrum & generate results
Import your adjusted AEM baseline file into Spectrum 1 1. In Spectrum click on the AIM-> Incidence-> Configuration (AEM) menu item 2. Locate your file in the file browser 3. Click Open 2 3
Your AEM file will now open in Excel
Generate your Spectrum files from within Excel 1 This creates two files: The SPT that passes the incidence results to Spectrum The SPU file that passes uncertainty curves 1. Click Create Spectrum Files in the AEM menu 2. Close the AEM Excel file (no need to save unless you want to) 2. Close the AEM file in Excel
Load your AEM results back into Spectrum 1. In Spectrum click on AIM-> Incidence->Load AEM result files 2.

Detailed step-by-step instructions are provided Compare your Spectrum & AEM projections using the Spectrum- AEM compare workbook
12. In AEM, Create Spectrum Files 1. Download & install latest version of Spectrum 6. Update your Spectrum file 7. Update ART program data in AEM 13. Load AEM incidence in Spectrum 2. Download and install AEM 5 8. Check ART infectivity reduction & weights are aligned 3. Verify Java is installed or install it 14. Make sure Spectrum uses the AEM F/M sex ratio Basic Steps in Updating Your AEM Projections 9. Update your AEM inputs 4. Let Spectrum know where your AEM and Java programs are installed 15. Display Results so Spectrum recalculates with AEM incidence 10. Update and adjust your AEM fit as needed 16. Compare Spectrum & AEM outputs 5.
