Table 1: Level 1 Findings: Data and Methods

CERT Population Finding
HMO Gout Patients There are limitations of administrative data for research on gout; this study showed that there were marked differences between men and women with gout with respect to epidemiology and treatment; administrative data may lead to misclassification.
UNC Pediatrics Use of statewide Emergency Dept. discharge database without medical record validation would be an inadequate approach for surveillance of drug-related anaphylaxis in children
HMO Ambulatory patients Error-detection phase of study led to creation of 10 HMO 2,000,000 person data set to support investigations into errors in drug prescribing in ambulatory setting
UNC Pediatric MEDMARX dataset is sufficiently powerful to identify trends in the pediatric population that warrant systems and process changes
HMO General population Automated claims and pharmacy databases are not sufficient on their own for assessing appropriate renal dosing to determine prescribing errors of QT interval prolonging medications
Penn Researchers Guidelines for the conduct of prospective meta-analyses
UAB Researchers/Practitioners Identification of tool (Achievable Benchmark of Care) for providing practitioners feedback (with benchmarks) on their performance to improve outcomes/compliance
HMO Chrug-Strauss Syndrome patients Development of algorithms using claims data that suggests patients with Chrug-Strauss Syndrome can be successfully identified using algorithms based on administrative data
UNC General population Found that many hospitals report adverse drug events differently in the emergency discharge database (ICD-9 and E codes) and the database has limitations to be used for identifying anaphylaxis related to drugs.
UNC Pediatrics Largest analysis of pediatric medication errors from the perioperative continuum of care. Used MEDMARX database in collaboration with USUHS to study drug-related anaphylaxis. Early findings suggest that pediatric patients are disproportionately vulnerable to an error medication.
HMO Pediatrics In study of prevalence of outpatient dosing errors, identified barriers to understanding the epidemiology of medication errors in children. Examples include prescribing medication that is not labeled for use in children, discrepancies in published dosing recommendations for many medications, unclear guidelines, and lack of readily available documented weights
Grantee General population/researchers Large multi-community randomized trial of an intervention to reduce antimicrobial resistance which innovatively linked health services measures with bacteria resistance patterns (nasopharyngeal carriage of resistant and susceptible S. pneumoniae)
Duke CHF inpatients A registry of inpatients with heart failure containing data on clinical history, demographics, medications, and treatment patterns to better understand outcomes associated with heart failure management.
Arizona General population The Web-based drug-induced arrhythmias registry (www.qtdrugs.org) has been accessed by individuals nationally and internationally. Attributed with providing the information that contributed to identifying the cardiotoxic effects of methadone.
