HAI HAI - HOSPITAL ASSOCIATED INFECTION HAI - HOSPITAL ACQUIRED INFECTION a NASO- COMIAL INFECTION HAI HAI HOSPITAL HAI - HEALTH CARE ASSOCITED INFECTION HEALTH CARE ASSOCIATED AFTER 24 hours Within 48 hrs Back with infection With in 30 days
HOSPITAL ASSOCIATED INFECTION When a infection manifested within 48 hours of admission. Patient is incubating from a outside infection. HOSPITAL ACQUIRED INFECTION These are infections that are a result of treatment in a hospital or a healthcare service unit. Infections are considered nosocomial if they first appear 48 hours or more after hospital admission or within 30 days after discharge. Nasocomial comes from the Greek word ‘ nasokomeio ’. noses= disease, komeo= to takecare of HEALTH CARE ASSOCITED INFECTION The modern CDC definition of hospital acquired infection is Healthcare associated infection. Healthcare-associated infections are infections that patients Acquire during the course of receiving healthcare treatment for other conditions
IMPORTANCE OF HAI In the United States , the Centers for Disease Control and Prevention estimate that 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.(Wikipedia)
PREVALANCE OF HAI • USA: Up to 2 million healthcare-associated infections per year, of which 80,000 are lethal or may contribute to death (3) • Europe: 5 million HAI per year, of which 50,000 (1%) are lethal and contribute to death in 135,000 cases (2.7%) (4) • Japan: Resistance Isolation Rate of MRSA (methicillin-resistant Staphylococcus aureus): 40-80% • India: An estimated 10 to 30% of patients admitted to hospitals and nursing homes acquire a nosocomial infection (5) • Up to 70% of organisms causing HAI are resistant to at least one antibiotic (6) (www.biomerieux-diagnostics.com/upload/HAI_KeyFigures.pdf)
