Respiratory diseases: meeting the challenges of screening, prevention, and treatment.

ABSTRACT

Respiratory conditions, both acute and chronic, continue to have a significant impact on worldwide health because of their high prevalence, the high disease burden they place on individual health, and their enormous cost to the health care system. There are also unmeasured indirect economic costs due to loss of productivity. Despite advances in our understanding of the complex pathophysiology of respiratory diseases, as well as the availability of relatively straightforward primary prevention measures, the prevalence of chronic respiratory diseases continues to rise. In addition, periodic outbreaks of acute infectious respiratory conditions result in significant cost and even mortality, and the incidence of these conditions fluctuates widely from year to year. Although we have seen recent developments in medical therapies for respiratory diseases, and there are established and well-publicized disease management guidelines, morbidity and mortality remain high. One intervention that has lagged behind has been smoking prevention and cessation, which is the mainstay of prevention for chronic obstructive pulmonary disease and lung cancer. The persistence of these conditions underscores vulnerabilities within our national and regional health care systems. Several of the articles in this issue of the NCMJ describe innovative programs to address these challenges.
