ABSTRACT
BACKGROUND: Aboriginal Community Controlled Health Services (ACCHSs) in Australia aim to optimise access to comprehensive and culturally safe primary health care (PHC) for Aboriginal populations. Central to quality service provision is the retention of staff. However, there is lack of published research reporting patterns of staff turnover and retention specific to ACCHSs. This study quantified staff turnover and retention in regional and remote ACCHSs in the Northern Territory (NT) and Western Australia (WA), and examined correlations between turnover and retention metrics, and ACCHSs' geographical and demographic characteristics. METHODS: The study used 2017-2019 payroll data for health workers in 22 regional and remote PHC clinics managed by 11 ACCHSs. Primary outcome measures included annual turnover and 12-month stability rates, calculated at both clinic and organisation levels. RESULTS: There was a median of five client-facing (Aboriginal health practitioners, allied health professionals, doctors, nurses/midwives, and 'other health workers' combined) and two non-client-facing (administrative and physical) staff per remote clinic, at any timepoint. Mean annual turnover rates for staff were very high, with 151% turnover rates at the clinic level and 81% turnover rates at the organisation level. Mean annual turnover rates for client-facing staff were 164% and 75%, compared to 120% and 98% for non-client-facing staff, at clinic and organisational levels, respectively. Mean 12-month stability rates were low, with clinic-level stability rates of only 49% and organisation-level stability rates of 58%. Mean annual clinic-level turnover rates were 162% for non-Aboriginal staff and 81% for Aboriginal staff. Both workforce metrics were moderately to highly correlated with the relative remoteness of clinics, size of regular clients serviced, and average annual headcount of employees in each clinic (p values < 0.01). CONCLUSIONS: Participating ACCHSs in remote NT and WA have very high turnover and low retention of healthcare staff. Overall, clinic-level turnover rates increase as distance from regional centres increases and are lower for Aboriginal staff, suggesting that greater employment of Aboriginal staff could help stabilise staffing. Improved retention could reduce burden on ACCHSs' resources and may also support quality of service delivery due to improved cultural safety and continuity of care.
