Socioeconomic status and patterns of care in lung cancer

This retrospective study aims to explore any associations between socioeconomic factors and lung cancer management and outcome in the Australian setting. The study population consisted of patients newly diagnosed with lung cancer in 1996 who were living in the Northern Sydney Area Health Service (NSAHS) or South Western Sydney Area Health Service (SWSAHS). These two Area Health Services differ in socioeconomic profiles based on socioeconomic indexes for areas (SEIFA), median income, education level and unemployment rate. Data on patient demographics, tumour characteristics, management details, recurrence and survival were collected, and the patterns of care were analysed. Socioeconomic status indicators of the two Area Health Services were imputed from the Australian Bureau of Statistics data. There were 270 and 256 new cases of lung cancer identified in NSAHS and SWSAHS respectively. Patients in NSAHS were slightly older (median age 73 versus 68 years) and there was less male predominance. The stage distributions and performance status of the two cohorts were similar. There were no significant differences in the utilisation rates of different treatment modalities between the two areas: radiotherapy (54% in NSAHS and 55% in SWSAHS), chemotherapy (34% and 25%), surgery (26% and 21%) and no treatment (22% and 25%). The 5-year overall survival was slightly in favour of NSAHS (10.5% and 7.4%), but did not reach statistical significance. Despite differences in socioeconomic profiles between the two area health services, patients with lung cancer had similar patterns of care and survival
