%X <B>OBJECTIVE: </B>To characterise diabetes-related lower extremity amputations (DRLEA) and prior contact with specialist podiatrists in Northern New Zealand.<BR><B>METHODS: </B>Using administrative data, DRLEA ≥35 years were identified for the Northern Region (July 2013 to June 2016). For those domiciled in Metro Auckland (July 2015 to June 2016), additional clinical data described amputation cause, diabetes-related comorbidities and podiatry contact.<BR><B>RESULTS: </B>There were 862 DRLEA for 488 people, including 25% (n=214) major amputations. Age-standardised amputation rates were three times higher for males than females (41.1 vs 13.6 per 100,000 population [95% confidence interval (CI): 37.3-44.9 vs 11.6-15.6 per 100,000] respectively). Amputation rates varied by ethnicity, being 2.8 and 1.5 times higher respectively for Māori and Pacific people than non-Māori, non-Pacific people. Mortality was high at 1-, 3- and 6-months post-admission (7.9%, 12.4 % and 18.3% respectively). There was high prevalence of peripheral vascular disease (78.8%), neuropathy (75.6%), retinopathy (73.6%) and nephropathy (58%). In the 3 months prior to first DRLEA admission, 65% were not seen by specialist podiatry.<BR><B>CONCLUSIONS: </B>Our study confirms higher DRLEA admission rates for Māori and males. We identified elevated rates among Pacific populations and observed suboptimal utilisation of specialist podiatry services.
