From page 18...
... . The current emphasis in developing alert systems is on assessing drug interactions rather than adverse drug reactions.
From page 19...
... , looks at its ability to detect drug-related injuries that present to emergency departments. The National Electronic Injury Surveillance System: Cooperative Adverse Drug Events Surveillance (NEISS-CADES)
From page 20...
... These data from Duke illustrate how voluntary reporting falls short of accurately reflecting the number of adverse events experienced by patients since 5 out of 6 events are missed.
From page 21...
... This creates a time lag between the occurrence of a drug event and the practitioner's ability to review medical data. One key benefit of computerized patient medical data is that they can be used to detect the frequency of adverse events and help identify methods to avoid them (Bates et al., 2003)
From page 22...
... . As of 2004, 57.4 percent of hospitals surveyed used clinical codes from medical records to monitor patient safety, and 50.8 percent used quality improvement programs and discharge data to monitor patient injuries and adverse events (Longo et al., 2005)
From page 23...
... The program recommends that patients also register with a drug information center, which has trained pharmacists who are able to record adverse event occurrences and recommend treatment for ADEs. These pharmacists would also be trained to record adverse clinical outcomes from medications and manage them effectively.
From page 24...
... This pooled information can be used to identify and track adverse events. Within the VA's database systems, the prescription database is merged with medical records, inpatient and outpatient files, and the mortality database.
From page 25...
... Dr. Santello commented that "although a paradigm for the assessment of causality using observational studies exists, it must be applied cautiously and deliberately before definitive conclusions can be drawn." She concluded that well-designed observational studies can supplement clinical trials and provide important additional information concerning the safety and effectiveness of therapeutic interventions.
