Definition of Hospital Acquired Infection
Hospital acquired infections (HAI) are defined as infections acquired in hospitals by a person and with no evidence that the infection was present or incubating upon entry into a healthcare facility.
Any infectious agent can be transmitted nosocomially,whether a bacterium, virus, fungus, parasite, or prion (WHO 2009).
NHS costs on HAI
Plowman et al 2001, says that HAI costs the hospital sector £930.62 million pounds. The NHS spends a lot on two bacteria that cause HAI, they are MRSA and Clostridium diffiicile.
It costs the NHS £4,000 on each case of infection caused by clostridium difficile. Experts say that every case of MRSA costs the National Health Service an extra £9,000 (Telegraph 2008)
