Socioeconomic Status and Distance to Reference Centers for Complex Cancer Diseases: A Source of Health Inequalities? A Population Cohort Study Based on Catalonia (Spain).

The centralization of complex surgical procedures for cancer in Catalonia may have led to geographical and socioeconomic inequities. In this population-based cohort study, we assessed the impacts of these two factors on 5-year survival and quality of care in patients undergoing surgery for rectal cancer (2011-12) and pancreatic cancer (2012-15) in public centers, adjusting for age, comorbidity, and tumor stage. We used data on the geographical distance between the patients' homes and their reference centers, clinical patient and treatment data, income category, and data from the patients' district hospitals. A composite 'textbook outcome' was created from five subindicators of hospitalization. We included 646 cases of pancreatic cancer (12 centers) and 1416 of rectal cancer (26 centers). Distance had no impact on survival for pancreatic cancer patients and was not related to worse survival in rectal cancer. Compared to patients with medium-high income, the risk of death was higher in low-income patients with pancreatic cancer (hazard ratio (HR) 1.46, 95% confidence interval (CI) 1.15-1.86) and very-low-income patients with rectal cancer (HR 5.14, 95% CI 3.51-7.52). Centralization was not associated with worse health outcomes in geographically dispersed patients, including for survival. However, income level remained a significant determinant of survival.

Smoking-attributable mortality in the autonomous communities of Spain, 2017.

INTRODUCTION AND OBJECTIVES: To estimate smoking-attributable mortality (SAM) in the regions of Spain among people aged ≥ 35 years in 2017. METHODS: SAM was estimated using a prevalence dependent method based calculating the population attributable fraction. Observed mortality was derived from the National Statistics Institute. The prevalence of smoking by age and sex was based on the Spanish National Health Survey for 2011 and 2017 and the European Survey for 2014. Relative risks were reported from the follow-up of 5 North American cohorts. SAM and population attributable fraction were estimated for each region by age group, sex, and causes of death. Cause-specific and adjusted SAM rates were estimated. RESULTS: Smoking caused 53 825 deaths in the population aged ≥ 35 years (12.9% of all-cause mortality). SAM ranged from 10.8% of observed mortality in La Rioja to 15.3% in the Canary Islands. The differences remained after rates were adjusted by age. The highest adjusted SAM rates were observed in Extremadura in men and in the Canary Islands in women. Adjusted SAM rates in men were inversely correlated with those in women. The percentage of total SAM represented by cardiovascular diseases in each region ranged from 21.8% in Castile-La Mancha to 30.3% in Andalusia. CONCLUSIONS: The distribution of SAM differed among regions. Conducting a detailed region-by-region analysis provides relevant information for health policies aiming to curb the impact of smoking.
