Hospital-acquired infection
Hospital-acquired infection (HAI) — also known as nosocomial infection — is an infection whose development is favored by a hospital environment, such as one acquired by a patient during a hospital visit or one developing among hospital staff. In the United States, the Centers for Disease Control and Prevention estimated roughly 1.7 million hospital-associated infections, from all types of microorganisms, including bacteria, combined, cause or contribute to 99,000 deaths each year. In Europe, where hospital surveys have been conducted, the category of gram-negative infections are estimated to account for two-thirds of the 25,000 deaths each year. Nosocomial infections can cause severe pneumonia and infections of the urinary tract, bloodstream and other parts of the body. Many types are difficult to attack with antibiotics, and antibiotic resistance is spreading to gram-negative bacteria that can infect people outside the hospital.Hospital-acquired infections are an important category of hospital-acquired conditions. HAI is sometimes expanded as healthcare-associated infection to emphasize that infections can be correlated with health care in various settings (not just hospitals), which is also true of hospital-acquired conditions generally.
