The spending of $15m in the funding of NSPs in South Australia from year 2000-2009 has resulted in a saving of $93m in healthcare costs, with more than 15,000 Disability Adjusted Life Years saved with a net financial saving of $80m. A summary of the return on investment of NSP funding in South Australia is shown in Table 28. The mathematical and economic modelling estimated that if NSPs are continued at the same level of funding in SA for the next ten years, $295m of net financial savings will accrue ($258m discounted at 3%) and for twenty years $605m ($458m discounted at 3%). The lifetime net present value of investment in NSPs that took account of all healthcare costs and savings (but not costs associated with productivity losses) would be $3.85bn ($1.26bn discounted at 3%).
