A study of patients undergoing elective bariatric surgery at Middlemore Hospital found that while National Bariatric Prioritization Tool (NBPT) score is not correlated with percentage total weight loss after 18 months, it is associated with improvement of comorbidities. Correlation coefficients for the association of NBPT score with reduction in glycosylated haemoglobin, resolution of obstructive sleep apnoea and resolution of hypertension were 0.28 (p < 0.0001), 0.20 (p < 0.001) and 0.20 (p < 0.001), respectively. NBPT scores were significantly higher for Māori and Pacific than New Zealand European patients (p = 0.0023). The study authors concluded that the NBPT could be used to achieve equity of access, but that further modifications should be considered to optimise outcomes.
