Hospitalized patients have a high risk of getting nosocomial infections due to various reasons. They tend to be more susceptible to infection because of their underlying disease condition, and they have higher when patients undergo invasive procedures. If the patient’s immune system is impaired, the non-pathogenic microorganism are capable of causing disease. Map is a method of illustrating an epidemiologic effectively . Maps can be used to show place of incidence. Mapping the incidence of nosocomial infections in Sultan Agung Hospital is a method developed for the surveillance of nosocomial infections. This type of research is a quantitative study with a cross sectional design. This study illustrates the risk factors of nosocomial infection with incidence of nosocomial infections that occur based on time point. Risk factors are extrinsic and intrinsic factors. Based on the spatial image on the map, in extrinsic incidence of nosocomial infections is Plebitis. Genesis Plebitis incidence correlates with the placement of hand washing points handrub. While the intrinsic factor in the Plebitis image and ILO most inpatient distribution in patients aged 50 years with impaired skin integrity due to infusion and physically due to decreased immunity associated with a variety of underlying diseases. Incidence of nosocomial infections in the inpatient unit is the primary predisposing factors such as age and clinical issues related predisposing underlying disease can weaken the immune system of the patient, so that the procedures and even the most basic medical treatment could potentially cause nosocomial infection.
