Compulsory Community Treatment Orders and health outcomes for Māori in New Zealand.

Background: We have previously analysed outcomes for all community treatment orders commenced during a 10-year period in New Zealand. Given Te Tiriti O Waitangi obligations to scrutinise health and consider equity for Māori, we completed this analysis to consider community treatment-order outcomes according to ethnicity.

Methods: Ministry of Health databases provided demographic, service use and medication dispensing data for community treatment-order recipients between 2009 and 2018. As non-Māori on community treatment orders are older, less deprived and less likely to be diagnosed with a Psychotic Disorder, data were categorised according to age (<35/⩾35 years), level of deprivation (New Zealand Dep levels ⩽3, 4-6 and ⩾7) and diagnosis (Psychotic Disorder/non-Psychotic Disorder). The incidences of key outcome measures (admissions, community care, medication dispensing) were calculated for periods on/off community treatment orders for Māori and non-Māori to consider the differential impact of community treatment orders according to ethnicity.

Results: Māori have high rates of community treatment order utilisation and are younger, more likely to be diagnosed with a Psychotic Disorder and spend longer receiving compulsory treatment than non-Māori. Non-Māori are more likely to receive more additional depot antipsychotic medication on-community treatment orders compared with periods off-community treatment order than Māori but other clear patterns of response distinguishing between Māori and non-Māori were not present.

Conclusion: The differences between Māori and non-Māori for community treatment-order utilisation suggest the presence of structural inequity in underlying mental illness distribution and treatment provision. Māori cultural expertise at all levels of healthcare including healthcare planning and delivery is required to make advances and reduce disparity.
