Lung cancer in New South Wales: current trends and the influence of age and sex

A total of 276 red foxes (Vulpes vulpes) was captured over 40 597 trap-nights during 1994–96 at three separate sites in central New South Wales, resulting in an overall trapping efficiency of one fox per 147 trap-nights. Trapping using multiple trap sets placed at carcases was 3.2 times more efficient than trapping using single trap sets. During 1994–95, when two of the sites suffered a severe drought, fox abundance declined to less than 0.2 foxes km–1 of spotlight transect; trapping efficiency at those sites also declined, to an average of one fox per 315 trap-nights. Mean trapping efficiency for non-drought periods was one fox per 135 trap-nights, 2.3 times more efficient than during the drought period. In 1995 and 1996, 353 foxes were shot in areas adjacent to each site. This gave the opportunity to compare sex and age biases between the trapped and shot samples: the ratio of males to females was significantly higher in the trapped sample than in the shot sample, and there was also a significantly higher ratio of adults to juveniles in the trapped sample than in the shot sample.

OBJECTIVE: To estimate the incidence and outcomes of sepsis hospitalisations in Aboriginal and Torres Strait Islander and non-Indigenous residents of New South Wales. DESIGN AND PARTICIPANTS: Prospective cohort study of residents aged 45 years and older, recruited between 2006 and 2009, and followed for hospitalisation for sepsis. MAIN OUTCOME MEASURES: Incidence and hazard ratio (HR) of sepsis hospitalisation and intensive care unit (ICU) admission identified using International Classification of Diseases (10th revision) coding on discharge data. Length of stay, readmission and mortality in those admitted for sepsis. RESULTS: Of 264 678 participants, 1928 (0.7%) identified as Aboriginal and/or Torres Strait Islander. Sepsis hospitalisation was higher in Aboriginal and Torres Strait Islander participants (8.67 v 6.12 per 1000 person-years; age- and sex-adjusted HR, 2.35; 95% CI, 1.98–2.80) but was attenuated after adjusting for sociodemographic factors, health behaviour and comorbidities (adjusted HR, 1.56; 95% CI, 1.31–1.86). Among those hospitalised for sepsis, after adjusting for age and sex, there were no differences between the proportions of Aboriginal and Torres Strait Islander and non-Indigenous participants admitted to an ICU (18.0% v 16.1%; P = 0.42) or deceased at 1 year (36.1% v 36.8%; P = 0.92). Aboriginal and Torres Strait Islander participants had shorter lengths of hospital stay (9.98 v 11.72 days; P < 0.001) and ICU stay (4.38 v 6.35 days; P < 0.001) than non-Indigenous participants. Overall, more than 70% of participants were readmitted to hospital within 1 year. CONCLUSION: We found that the rate of sepsis hospitalisation in NSW was higher for Aboriginal and Torres Strait Islander adults. Culturally appropriate, community-led strategies targeting chronic disease prevention and the social determinants of health may reduce this gap. Preventing readmission following sepsis is a priority for all Australians.
