Welcome to the EUSCREEN cost-effectiveness model.
With the EUSCREEN model, the cost-effectiveness of a hearing or vision screening programme for children can be calculated for your country or region, taking your local circumstances into account.
The model works like this: the user enters relevant parameters for an existing or hypothetical screening programme, such as how many children are born, which tests are used, which professionals perform the testing and so forth. The model subsequently simulates this screening programme and calculates how many cases will be detected, at what cost and so on. These results are presented to the user on the web page. There is also an option to download both a simulation’s input data and results as a pdf file. A saved simulation can be loaded again at a later time and changes can be made, in order to calculate the effects a change in for example screening age or professional will have. Once three simulations have been saved, the results of these are presented side-by-side for easy comparison. The results are presented as graphs as well.
A good way to start with the model would be to first calculate the cost-effectiveness of your current screening programme if one is present, because data about the current screening programme will be most easily accessible to you. The programme calculates the number of tests, number of referrals to diagnostics, number of cases detected, costs of screening until referral, costs of diagnostic assessments, total costs, costs per test and costs per case detected. After this, you can adjust variables to see what effect a change of screening professional, screening test, age of screening, number of screening steps, etcetera will have.
It is important to realise that the accuracy of the prediction is dependent upon the variables you supply. Notably, the sensitivity and specificity of a screening test, performed by a given professional at a given age, are often unknown and you will have to make estimates.
This version of the model is a preliminary version, to be used for testing. All feedback and comments are welcome and will be used to improve the model. Feedback and comments can be sent to this email address.
There are several functions of the model that have not yet been implemented but are scheduled to be added in the future, for example: default values for test sensitivity and specificity, specification of overhead costs, changes in utility and quality of life, preverbal vision screening tests , childhood hearing screening after the neonatal period, photoscreening and treatment.
The EUSCREEN team would like to thank everyone who tests the model, as the contributions of the testers are invaluable in further developing and refining the model.
