In this class, household final consumption involves the acquisition of consumer durables, meaning goods that may be used for health primary purposes of consumption repeatedly or continuously over a period of a year or more (SNA 2008, 9.42). Household improvements are to be accounted for as investment: automatic staircase lifts for patients with mobility limitations; bathtub lifts and similar devices for adapting the housing situation of patients with transitory or chronic impairments, and hire of therapeutic equipment. For information on whether the fixed equipment described here is to be accounted as capital formation or current expenditure see Chapter 11.
