Aspiration Pneumonia After Stroke

Fifteen million strokes occur worldwide each year with 5 million associated deaths and an additional 5 million people left permanently disabled. In the United States, about 780 000 people suffer a new or recurrent stroke each year. There were an estimated total 5.8 million stroke survivors as of 2008. Mortality from stroke is the third leading cause of death in America following heart disease and cancer. Chest infection may affect up to as many as one-third of stroke patients. This increases the morbidity and mortality of this patient population. Pneumonia causes the highest attributable mortality of all medical complications following stroke. A comprehensive multidisciplinary team approach is required at the hospital level. This requires active administrative commitment and participation. Implementation of evidence-based management strategies can improve outcomes and reduce costs. We sought to review the problem of post-stroke pneumonia and discuss strategies for prevention and intervention.
