Is race/Ethnicity associated with mortality in the PICU?
Although gender, age, and diagnosis showed an effect on severity of illness-adjusted PICU mortality, race/ethnicity did not. Additional investigation is warranted because the present results (ie, insurance type) may be proxy measurements for other influences not collected in this database, such as sociocultural and socioeconomic factors.
Depression was independently associated with a 1.6-fold increased risk for 7-year mortality, above and beyond anxiety and Type D personality. Future studies are warranted to further elucidate the potential pathways linking depression to long-term mortality following PCI.
