Health of children in Australian immigration detention centres: An analysis of the quarterly health reports from 2014 to 2017

AIM: This study examines 3 years of child and adolescent health data from Australian onshore and offshore immigration detention centres from 2014 to 2017, quantifying the health presentation data of children and adolescents in Australian immigration detention and comparing rates between onshore and offshore detention. METHODS: This study utilised the Quarterly Immigration Detention Health Reports over a period of 3 years. To compare onshore and offshore datasets, we calculated the rate of health events per quarter against the estimated quarterly onshore and offshore detention population of children. We ran a series of two‐proportion z‐tests for each matched quarter to calculate median z and P values for all quarters. These were used as an indicator as to whether the observed differences between onshore and offshore events were statistically significant. RESULTS: The estimated number of children detained per quarter onshore ranged from 700 in 2014 (quarter 3) to 13 in 2016 (quarters 3 and 4); the estimated quarterly population of children in offshore detention ranged from 186 in 2014 (quarter 3) to 42 in 2017 (quarter 2). Children offshore had significantly higher rates of consultations with a mental health nurse (z = −1.96; P = 0.002), psychologist (z = −2.32; P = 0.01) and counsellor (z = −3.41; P < 0.001). As for reasons for presentation to general practitioners and psychiatrists, complaints related to skin (z = −1.97; P = 0.05), respiratory issues (z = −1.96; P = 0.05) and urological issues (z = −2.21; P = 0.03) were significantly higher amongst children detained offshore. CONCLUSIONS: Compared to children in the Australian community, children detained both onshore and offshore had greater health needs. Children offshore also presented more frequently with a range of complaints and accessed health services at higher rates than children detained onshore; this adds to growing evidence about the harms of offshore detention and detention more generally.
