  1. 1An annual increase for the following parameters was assumed: 5% annual increase in client population, 5% annual increase in uptake of the preventive care consultation, 2.1% annual increase in the salary of the specialist clinician, and a 5% annual increase in the incremental effectiveness of the intervention. In line with these increases, an incremental annual increase in implementation costs (administrative, telephone calls, printing and travel) was calculated accordingly;
  2. 2Represents the number of clients estimated to be eligible to attend the additional consultation i.e. excluding those identified as too unwell (based on trial data);
  3. 3The intervention is an add on to Usual Care, hence all its costs are the incremental costs;
