Abstract Background Epidemiological data on carbon monoxide poisoning (COp) are limited. Our aim is to describe changes in rates of hospital admissions for accidental non-fire related (ANFR) COp in England (2002-2016), and compare temporal trends to those seen in other high-income countries.
Methods
We analysed data on hospital admissions with a primary diagnosis of ANFR COp. Rates per 100,000 inhabitants were estimated by age, sex and calendar-year. Temporal trends were analysed using piecewise log-linear models and changes shown as annual percent change (APC). Trends for England were compared to those in the US, Spain and France. We fitted an ecological regression to assess the impact of deprivation and ethnicity on the age-/sex-adjusted risk of ANFR COp hospitalization.
Results
We identified 3,391 admissions (0.43/100,000inhabitants). Most occurred during the winter months (51.8%). Higher rates occurred among men (0.46 vs. 0.40), the most deprived (0.50 vs. 0.33) and rural areas (0.51 vs. 0.42). Preliminary results show a significant decrease in the rates among women only between 2008 and 2016 (APC: -7.9% (95%CI: -12.5;-2.5)). England showed similar rates to Spain and US but not France, which were twice as high. Ethnicity and deprivation also appeared to influence admission risks.
Conclusions
Nationally, rates decreased only in women (2008-2016). Admissions were more common among men, the over 80 year olds, black/black British and highly deprived groups. Proposals to help raise awareness among these groups are needed for consideration.
