History of nosocomial infection

Initially, in 1841 an obstetrician resident of Hungary named Ignaz Semmelweis practicing as a physician in Vienna maternity hospital found that suddenly death rates of women involved in childbirth are accelerating due to puerperal fever, which is a disease caused because of Nosocomial infection. The infected ladies initially suffered from fever caused by developing uterine infection. Further, the physician conducted survey in wards where women were giving birth to babies and place where medical students were working on cadavers. The physician was shocked when he found at such places the nosocomial infection rate was 20 times higher than other places in hospital, infecting staffs helping women during child birth. Thus, the physician made it mandatory to use disinfectants for hand wash in May 1847 and result came very positive as the rate of nosocomial infection declined.


Diseases associated with nosocomial infection and how it gets transmitted

There are several diseases that are associated with nosocomial infection, but of several diseases the most common are hospital-acquired pneumonia, ventilator-associated pneumonia, urinary tract infection, gastroenteritis, puerperal fever, and so on. The nosocomial infection generally gets transmitted by direct contact with infected person, by droplets that may come from infected person when they cough, sneeze, vomit, bleeding, talking sitting close to them, and by other similar means. Further, the nosocomial infection also gets transmitted by any items used by the infected patient, which includes their utensils, food, water, medicine, and equipments used to treat them. In addition, the nosocomial infection also infects other people by the way of parasite carrying insects and mammals like mosquitoes, rates, flies, and other pet animals that the infected person handles.


How healthcare institutions across the world handling nosocomial infection?

If we talk about most developed nations especially USA we can find approximately 1.7 million hospitals are infected with nosocomial infection causing bacteria and associated microbes, which cause around 99,000 deaths in a year. Further, in European countries the deaths caused due to nosocomial infection were around 25,000 in a year. In this regard, the best preventative measures were prescribed and implemented in Maryland State of the USA, which offered rewards and even penalties to health care centersby evaluating rate of nosocomial infection in their institutions. The protective measures that were prescribed was sterilization of equipments and clothes of the patients, isolation where the nosocomial infected patients were kept in special rooms, frequent hand washing by using best disinfectants, usage of gloves as well as their decomposition after usage, sanitizing surfaces by applying non-flammable alcohol vapor in carbon dioxide systems, and by using antimicrobial surfaces made of copper, silver, and other germicide compounds.


Maryland State of the USA discovered after two years and found that after launching the program the rate of nosocomial infection fell till approx 15%in healthcare institutions. Further, if we compare the infection rate decreased from 2.38 in year 2009 to 2.02 in year 2011. In addition, the decline of 15.26% constitutes around $ 100 million saving in healthcare institutions of Maryland. Thus, the world can learn a lot from such kind of government policies that helps in combating nosocomial infection.


What is the status of Indian healthcare institutions when it comes to nosocomial infection?

As per different researches conducted by Global Antibiotic Resistance Partnership (GARP) and India Working Group and Centre for Disease Dynamics, Economics and Policy (CDDEP) says that there is high risk of nosocomial infection in Indian healthcare centers even in ICUs and general wards. In year 2011GRAP stated that HAI can be controlled by using preventative measures adopted by Maryland healthcare centers.


The most common infection causing organisms like S. aureus and P. aeruginosacarrying the infection causing pathogens found across the world were also found in Indian hospitals. Further, according to the study conducted by Post Graduate Institute of Medical Education and Research (PGIMER) in Chandigarh out of 71 patients 59 patients in burn units were infected with nosocomial infection, which constitutes around 83% overall infection spreading rate. Another, research conducted by All India Institute of Medical Sciences (AIIMS) in New Delhiin year 2001 put forward findings that were really shocking as it stated out of 1,253 patients in ICUs 140 patients spread acquired infection in hospital to 152 patients, which constitutes around 11% rate of nosocomial infection.
