In order to simulate a screening programme, at least the following information is necessary:

For hearing screening

  • number of children born per year in your area (can be a country, region or district)
  • what part of children are born in a (maternity) hospital?
  • which professional(s) perform screening?
  • what is the salary per month for these professional(s)?
  • what does an OAE device cost?
  • how many OAE devices will be needed?
  • after how many years will the OAE devices need to be replaced?
  • what does an aABR device cost?
  • how many aABR devices will be needed?
  • after how many years will the aABR devices need to be replaced?
  • how much does one audiololgic diagnostic examination (after screening) cost?

For vision screening

  • number of children born per year in your area (can be a country, region or district)
  • at what ages do children attend kindergarten?
  • what part of children attend kindergarten?
  • from what age is school compulsory?
  • what part of children attend primary school?
  • which professional(s) perform screening?
  • what is the salary per month for these professional(s)?
  • what does a visual acuity chart cost?
  • how many vision charts will be needed?
  • how much does a diagnostic examination by orthoptist or ophthalmologist (after screening referral) cost?

The model will provide the following results of a simulation

  • number of tests
  • number of referrals to diagnostic examination
  • number of cases confirmed by diagnostic examination
  • percentage not diagnosed before age 1 (hearing) or age 7 (vision)
  • number of screens per case detected
  • costs of screening until referral to diagnostic assessment
  • cost of diagnostic assessment
  • total costs (screening + diagnosis)
  • costs per test
  • costs per case detected
