 Each year community acquired pneumonia CAP causes 61,000 hospital admissions 2006-7 data and incurs costs of more than AUD300 million in Australia. At the investigators institution, over 1000 admissions per year have an average hospital length of stay LOS of 5 days and incur average clinical costs of AUD6,724 per admission 201213 data. Prolonged LOS not only has significant implications for organizational costs but is also strongly associated with adverse patient outcomes including loss of function due to de-conditioning and higher incidence of hospital-acquired adverse events including hospital-acquired infections, intravascular-device associated complications and antibiotic-related side effects. Reducing LOS therefore benefits both the patient and the health system. General Internal Medical GIM services manage the largest proportion of CAP patients at Western Health, with 47 of CAP admissions managed by GIM in 201213 average age 75 with proportions with at least 1, 2 or 3 active co-morbidities 70, 43 and 27 respectively. With population ageing, the elderly and highly multi-morbid population treated by GIM units will constitute the bulk of Australias future health service burden for CAP.
