Economics of high-frequency home monitoring versus clinic-based perimetry
Clinic perimetry is very reliable but requires specialized equipment (like a Humphrey Field Analyzer) and trained staff. It can be costly and...

A decision model is a structured way to compare different choices and predict their likely outcomes over time. It uses data, assumptions, and math to estimate what might happen if you choose one option over another, such as different treatments, policies, or programs. Common types include simple decision trees and more complex simulations that track events over long periods. The model integrates probabilities (how likely events are), outcomes (like health improvements or side effects), and costs to calculate expected results for each option. Decision models matter because trials and studies can’t always show what will happen in the real world over many years, and they can’t test every possible choice. By combining the best available evidence, a model helps decision-makers see the likely consequences of different actions and weigh trade-offs. Models also let you test how sensitive results are to uncertainty by changing inputs and seeing how outcomes shift. Their reliability depends on the quality of the data and assumptions used, so good models are transparent and examine uncertainty carefully. When used properly, they are powerful tools for planning, budgeting, and choosing policies that improve health outcomes.
