Detecting adverse events for patient safety research: a review of current methodologies <s> Nosocomial infection detection systems <s> At the LDS Hospital in Salt Lake City, an interface was developed between the microbiology laboratory computer system and the HELP integrated central hospital computer system. The HELP system includes medical information from most clinical care support areas. The microbiology data are translated from the laboratory computer file structure to a hierarchical data structure on the HELP system. A knowledge base was created with the help of infectious disease experts, and became part of a Computerized Infectious Disease Monitoring system (CIDM). The knowledge base is automatically activated when specific microbiology data are entered into a patient's computer file (data driven), thus decisions are made automatically with no additional effort required of medical personnel. The CIDM was designed to inform infectious disease personnel when a patient has one of the following conditions: a hospital-acquired infection, an infection at a normally sterile body site, an infection due to a bacteria with an unusual antibiotic sensitivity pattern, an infection for which the patient is not receiving an antibiotic to which the offending bacteria is sensitive, an infection that could be treated with a less expensive antibiotic, an infection which is required by law to be reported to state and national health authorities, and those patients receiving prophylactic antibiotics longer than is medically indicated. All of the microbiology data are now extensively reviewed by nurses and physicians from terminals at nursing stations or intensive care units. The CIDM is currently being used for hospital-acquired infection surveillance at LDS Hospital. <s> BIB001 </s> Detecting adverse events for patient safety research: a review of current methodologies <s> Nosocomial infection detection systems <s> Surveillance of hospital-acquired infections and antibiotic use is required of US hospitals. The time and cost needed to actively perform this surveillance can be extensive. We developed a computerized infectious disease monitor that automatically generates four types of surveillance "alerts" for patients (1) with hospital-acquired infections, (2) not receiving antibiotics to which their pathogens are susceptible, (3) who could be receiving less expensive antibiotics, or (4) who are receiving prophylactic antibiotics too long. Surveillance personnel using computer screening for two months found more hospital-acquired infections when compared with our traditional surveillance methods, while requiring only 35% of the time. In addition, alerts from the computer identified 37 patients not receiving appropriate antibiotics, 31 patients who could have been receiving less expensive antibiotics, and 142 patients, during one month, receiving prolonged cephalosporin prophylaxis. Computer screening can help focus the activities and improve the efficiency of hospital surveillance personnel. ( JAMA 1986;256:1007-1011) <s> BIB002
Several groups have successfully developed nosocomial infection event monitors BIB001 . When compared to manual review, computerized surveillance has superior sensitivity and required less person time BIB002 . These systems typical work by searching clinical databases for signals and then generating an alert for hospital infection control personnel.
