* * * * * As a result of age shifts in the US population, Angus et al predict that the incidence of severe sepsis will outstrip the growth in population over the next 50 years. Indeed, the incidence of severe sepsis is expected to increase by approximately 1.5% per annum for the next fifty years. This increase poses substantial problems and argues for the need for improved therapy of severe sepsis and suggests that the supply of critical care physicians will soon be unable to meet societies demands. In 1997, intensivists provided care to 36.8% of all ICU patients. Angus et al suggest that the current ratio of supply to demand will remain in rough equilibrium until 2007. Subsequently, demand should grow rapidly while supply will remain near constant. This imbalance will yield a shortfall of specialist hours equal to 22% of demand by 2020 and 35% by 2030, primarily because of the aging of the US population.
