Avoidable hospital admissions

Ambulatory Care Sensitive Conditions (ACSC) are those for which hospitalisation is thought to be avoidable if preventive care and early disease management are applied. Table 16 summarises the admission rates for the top 10 ACSC for the City of Boroondara (in 2014-15 and 2015-16) and the Melbourne Metropolitan region (in 2015-16).

Dental conditions were the most common cause of hospitalisation in Boroondara with a rate of 4.2 per 10,000 persons followed by iron deficiency anaemia (2.9 per 1,000 persons).

In 2015-16, admissions due to dental condition and iron deficiency anaemia increased by a 13% and 16% respectively compared to the previous period. Of the top 10 ACSC for Boroondara in 2015-16, only dental conditions, and asthma recorded higher rates of hospital admission than metropolitan Melbourne.

Females, and residents aged 5-9 years, 15-19 years, and 20-24 years recorded higher admission rates for dental conditions. Congestive heart failure was the leading cause of admission for residents aged over 80 years.

Table 6  shows the average number of bed days for the top 10 avoidable hospital admission conditions in 2015-16 in Boroondara and metropolitan Melbourne. Congestive cardiac failure caused the longest average length of stay (8 days) followed by diabetes complications (6.1) and urinary tract infections, including pyelonephritis (5.7).
