Cost-Effectiveness Analysis and Economic Modeling
A cost-effectiveness analysis answers the question every payer and health system now asks: is this intervention worth what it costs, compared with the alternative? EvySaif builds transparent, decision-ready economic models that quantify that value, from cost-effectiveness and cost-utility analyses to budget-facing cost calculators, reported to the CHEERS 2022 standard so the work stands up to scrutiny.
Models built to be understood and trusted
Health economic models only persuade when a reviewer can follow them. We report to the Consolidated Health Economic Evaluation Reporting Standards (CHEERS 2022), the ISPOR good-practice checklist recognised by the EQUATOR Network, which means the model is identifiable, interpretable, and replicable.
Choose the structure
We build decision-analytic models, including decision-tree and Markov cohort structures, over a time horizon appropriate to the intervention and the decision.
Integrate the inputs
Clinical effect, costs, and quality-of-life data are integrated into the model, with every assumption documented rather than borrowed uncritically from a template.
Estimate the value
The output is the incremental cost-effectiveness ratio (ICER), expressed per quality-adjusted life year (QALY) in a cost-utility analysis or per clinical outcome in a cost-effectiveness analysis, so very different interventions can be compared on one scale.
Show the uncertainty
Deterministic and probabilistic sensitivity analysis make the uncertainty around the estimate visible rather than hidden, presented through cost-effectiveness planes and acceptability curves.
Demonstrated modeling experience: we have built a full decision-analytic cost-effectiveness model from scratch, complete with ICER, return-on-investment, probabilistic sensitivity analysis, and budget impact, verified across multiple model versions and prepared for a peer-reviewed health economics journal.

How EvySaif helps
We build models that a payer or peer reviewer can actually follow, document every assumption, and report to CHEERS 2022 from the outset. For the India and Middle East markets, we adapt cost inputs and cost-effectiveness thresholds to the local setting, which matters now that Gulf payers are formalising economic evaluation requirements.
Why EvySaif
EvySaif is one of the best research and medical writing consultancies in India, and we bring that standard to every project. Our modeling is clinician-led, so the clinical assumptions behind the numbers are sound, not borrowed uncritically from a template. We build models that a payer or peer reviewer can actually follow, document every assumption, and report to CHEERS 2022 from the outset.
Frequently asked questions
CHEERS 2022, the ISPOR Consolidated Health Economic Evaluation Reporting Standards, which is recognised by the EQUATOR Network and increasingly expected by journals and HTA bodies.
A cost-effectiveness analysis measures outcomes in clinical units (for example, cost per event avoided). A cost-utility analysis measures them in quality-adjusted life years (QALYs), which lets very different interventions be compared on one scale.
Yes. We adapt global core models to India and Middle East cost data and cost-effectiveness thresholds, which is essential for local reimbursement.
