Table 3 Summary of Aboriginal health practitioner workforce metrics, by community population size and type

From: Patterns of resident health workforce turnover and retention in remote communities of the Northern Territory of Australia, 2013–2015

Population size category of remote community Number of clinics Mean annual AHP turnover (%) (95% CI) Mean AHP annual stability (%) (95% CI) Mean number of pay periods per year with an AHP who has remained for 2 or more years (95% CI)a Mean survival probability for AHPs after 12 months (95% CI) Average survivalb time for AHPs in years (95% CI)
<200 predominantly Aboriginal 6 75.7 (29.7, 193.4) 75.0 (37.9, 100.0) 8.0 (6.8, 9.3) 0.09 (0.00, 0.35) 0.31 (0.08, 0.88)
