Prognostic risk factors for stroke-associated pneumonia

Stroke impacts patient's quality of life, but most stroke patients die of complications, such as pulmonary infections, rather than the original stroke. Stroke-associated pneumonia (SAP) is a common complication of acute stroke, but the risk factors are poorly understood. SAP can significantly affect neurological recovery after stroke and markedly prolong the hospital stay. The present study analyzed the risk factors for SAP to improve prevention and treatment outcomes. Age, diabetes mellitus, states of consciousness, nasal feeding, gastric mucosa protective drugs, and prophylactic use of antibiotics are risk factors for SAP. In addition, smoking, cardiovascular disease, stroke location and properties, and dehydrating agents are associated with SAP, but are not risk factors.
