BACKGROUND: It is unknown how anemia influences the invasive management of patients with non-ST-segment elevation myocardial infarction (NSTEMI) and associated mortality. We investigated whether receipt of cardiac catheterization relates to 6-month death rates among patients with different severity of anemia. METHODS: We used data from the population-based Worcester Heart Attack Study, which included 2634 patients hospitalized with confirmed NSTEMI, from three percutaneous coronary intervention-capable medical centers in the Worcester (Massachusetts, U.S.A.) metropolitan area, during five biennial periods between 1997 and 2005. Severity of anemia was categorized using admission hematocrit levels: less than or equal to 30.0% (moderate-to-severe anemia), 30.1-39.0% (mild …

A Systematic Review Of Validated Methods For Identifying Heart Failure Using Administrative Data, Jane Saczynski, Susan Andrade, Leslie Harrold, Jennifer Tjia, Sarah Cutrona, Katherine Dodd, Robert Goldberg, Jerry Gurwitz

Jennifer Tjia

PURPOSE: To identify and describe the validity of algorithms used to detect heart failure (HF) using administrative and claims data sources.

METHODS: A systematic review of PubMed and Iowa Drug Information Service searches of the English language was performed to identify studies published between 1990 and 2010 that evaluated the validity of algorithms for the identification of patients with HF using and claims data. Abstracts and articles were reviewed by two study investigators to determine their relevance on the basis of predetermined criteria.

RESULTS: The initial search strategy identified 887 abstracts. Of these, 499 full articles were reviewed and 35 …

A Systematic Review Of Validated Methods For Identifying Cerebrovascular Accident Or Transient Ischemic Attack Using Administrative Data, Susan Andrade, Leslie Harrold, Jennifer Tjia, Sarah Cutrona, Jane Saczynski, Katherine Dodd, Robert Goldberg, Jerry Gurwitz

Jennifer Tjia

PURPOSE: To perform a systematic review of the validity of algorithms for identifying cerebrovascular accidents (CVAs) or transient ischemic attacks (TIAs) using administrative and claims data. METHODS: PubMed and Iowa Drug Information Service searches of the English language literature were performed to identify studies published between 1990 and 2010 that evaluated the validity of algorithms for identifying CVAs (ischemic and hemorrhagic strokes, intracranial hemorrhage, and subarachnoid hemorrhage) and/or TIAs in administrative data. Two study investigators independently reviewed the abstracts and articles to determine relevant studies according to pre-specified criteria. RESULTS: A total of 35 articles met the criteria for evaluation. …
