Lister used this to sterilize equipment | carbolic acid |
CDC estimates HAI’s cost this much per year | 30 billion |
Most common HAI | UTI |
3 most common SERIOUS HAi illnesses | Surgical site infx, pneumonia, Bacteremia |
Most common Gram + HAI bugs | Staph aureus, Coag negative Staph, Enterococci sp. |
Most common Gram – HAI bugs | E. coli, Pseudomonas, Enterobacter sp., Klebsiella |

NHSN stands for | National Healthcare Safety Network |
NHSN date organized in these 4 categories | Patient Safety, Healthcare personnel safety, Biovigilance, R&D |
The Cause | Etiology |
Number of cases resulting in illness/poor health | Morbidity |
Number of cases resulting in Dealth | Mortality |
Occurrence of disease greater than would be expected in a particular place &time (community) | outbreak |
sudden and widespread outbreak of disease within population, group or specific area | epidemic |
ongoing process of disease within population. group, or specific area | endemic |
occurs over large geographic areas, possibly worldwide | pandemic |
number of new cases of disease or injury in population during a specific time period | incidence |
TOTAL number of cases of disease or injury in a population at a particular point in time or during a specific time period | prevalence |
Who collects data to determine outbreaks vs epidemics vs pandemics | local and state health departments then CDC |
Worldwide Agency that monitors EIDs | WHO |
2 most important population properties for disease spread | Density and susceptibility |
Theorys how/why EIDs still exist | World travel, humans encroaching on undeveloped areas, immigration, poor human hygiene, over/mis-use of ABX, population growth |
