Objectives: This study aims to estimate the incidence rate of first episode of psychosis (FEP) in the Top End of the Northern Territory (NT), exploring how rates vary by age, sex, Aboriginal status and remoteness. Method: Youths (ages 15–24) presenting with FEP to the two specialist mental health services in the Top End were identified through audit of the electronic health records between 2014–2018. Population demographic data were collected from the 2016 Australian National Census. Statistical analysis estimated variation in incidence rates by age, sex, Aboriginal status and remoteness. Results: A total of 236 youths with FEP were included in the study. The overall incidence rate was 174 per 100,000 person-years. Rates were very high in the Aboriginal (331 per 100,000 person-years) and remote populations (308 per 100,000 person-years), and lower in the non-Aboriginal population (85 per 100,000 person-years). Conclusion: This study shows high rates of FEP in young people in the Top End, attributable to very high rates in the Aboriginal population, many of whom live in remote areas. Resources should be allocated to support this high-risk group. [ABSTRACT FROM AUTHOR]

Objective: To investigate trends in hospital admissions involving suicidal behaviour in the Northern Territory (NT) resident population over the period 2001-2013.Methods: Estimates of age-standardised rates and average changes in the annual rate of hospital admissions involving suicidal behaviour were calculated by socio-demographic characteristics and types of suicidal behaviour.Results: Overall rates for Indigenous admissions were 2.7 times higher than non-Indigenous admissions and had increased by almost twice as much. While male and female rates of admission were similar for both Indigenous and non-Indigenous residents, the average annual change in rates was greater for Indigenous females (13.4%) compared to males (8.8%) and for non-Indigenous males (7.7%) compared to females (5.2%). Younger and middle-aged Indigenous admissions experienced increasing rates of admissions, whilst trends were similar across age groups for non-Indigenous admissions. Admissions with a diagnosis of suicidal ideation increased the most across all groups. Trends in intentional self-harm admissions differed according to Indigenous status and sex.Conclusions: There have been substantial increases in hospital admissions involving suicidal behaviour in the NT, most markedly for Indigenous residents. Indigenous females and youth appear to be at increasing risk. The steep increase in suicidal ideation across all groups warrants further investigation. [ABSTRACT FROM AUTHOR]
