Health disparities often reflect inequitable access to appropriate health care. This study aimed to establish if cases of genital chlamydia infection were managed equitably by age, gender and ethnicity in a region of New Zealand with high rates of chlamydia infection (858 per 100,000 population). Clinical records of 415 genital chlamydia cases from 19 different health-care sites, including general practice and community settings, were reviewed. Data were analysed by demographic variables. For those treated, men were treated more quickly than women (median 3 days versus 6 days, P < 0.001), but there was no difference by ethnicity. Cases without documented treatment were more likely to be women (8.2% versus 2.1%, P = 0.037) and more likely to be Māori than non-Māori (13.6% versus 4.8%, P = 0.036). Overall, the most notable issue was the lack of effective partner notification across all demographic variables. Ongoing efforts are required to ensure equitable access to timely treatment and to ensure that more effective partner notification strategies are implemented.
