years are also considered in this analysis. Section E.1 describes data sources that are selected to inform the current analysis. Section E.2 estimates the likely extent of use for insertion of a partially implantable active middle ear implant over the next five years. The projected use of implantation of a partially implantable active middle ear implant is determined on the basis of the estimated Australian population growth of 1.7 % per year (available online: ; downloaded 2015-09-23), which will influence the increase of number of patients per year. Besides the overall usage the financial implications associated with the expected usage are quantified. Section E.3 provides an estimation of changes in use and cost of other medical services. Section E.4 determines the estimated net financial implications of the proposed treatment for the MBS in each year over the next five years. Section E5 provides a detailed sensitivity analysis of the parameters used in the economic model addressing possible sources of uncertainty. An electronic spread sheet with calculations contained in section E is provided in Attachment F. E.1 Justification of the selection of sources of data A literature search, though not systematic, was carried out using the search terms prevalence OR together with common outer ear pathology “incidence OR epidemiology” terms externa OR (ear) exostosis OR earwax OR to identify “otitis cerumen” epidemiological research. The best available evidence was used to conduct the estimation of the use of the proposed listing. E.1.1 Prevalence of hearing loss in Australia according to DAP According to the decision analytical protocol provided by PASC, in Australia SNHL is the most common form of hearing loss. The overall prevalence of hearing loss dBHTL in ≧25 adults is 20.2 % for SNHL, 0.4 % for CHL and 1.6 % for MHL (Table 59). In adults, SNHL is largely caused by ageing, with most people aged over 50 years. Sensorineural hearing loss may also be caused by congenital malformation and exposure to noise or ototoxic substances. There are more adult males with hearing loss than females (26.3 % males vs. 17.1 % females). In adults, 66 % have mild hearing loss; 23 % have moderate hearing loss and 11 % have severe to profound hearing loss.
