Remoteness and socioeconomic status reduce access to specialist mental health care across Australia.

OBJECTIVE

Estimate impact of socioeconomic factors and remoteness from tertiary hospital on incidence/duration of Australian mental health admissions.

METHODS

Retrospective analysis of incidence/duration of public mental health unit admissions (2018-19). Covariates included Indigenous population, potentially preventable hospitalisations (PPH) and socioeconomic disadvantage.

RESULTS

Regional distance from hospital was correlated with socioeconomic disadvantage (: < 0.01). Population identifying as Aboriginal or Torres Strait Islander was associated with distance from hospital, socioeconomic disadvantage and PPH (: < 0.01). Bed days per capita was explained (: 0.48) by distance and socioeconomic disadvantage ( < 0.0001). A 1% increase in distance from hospital was associated with a 0.37% decrease in per capita bed days. Admission rate per capita across Queensland and WA was explained (: 0.36) by distance, education/occupation and state ( < 0.05). Across Queensland and WA a 1% increase in distance from hospital was associated with a 0.05% decreased incidence of admission.

CONCLUSIONS

Rural Australians face high mental illness burden, socioeconomic disadvantage and limited service provision. Overcoming the additional disadvantages of reduced likelihood of admission to and reduced time in hospital with increasing distance from hospital will require increased outreach proportional to remoteness.
