| Popis: | Background: A new transient ischemic attack (TIA) is a risk factor for a future vascular event. Reducing that risk requires a timely diagnostic workup and delivering secondary stroke preventive services. It is unknown whether such care should be performed in the inpatient or outpatient setting. Methods: Using administrative databases, we identified all veterans with a diagnosis code for TIA assigned in the emergency department or urgent care setting in the Veterans Health Administration during fiscal year 2008. We calculated the proportion who were admitted and predictors of admission. At one-year after presentation of TIA, we examined the proportion who were assigned a new diagnosis code for stroke, myocardial infarction, or death. We then determined whether admission was associated with outcomes using chi-square and multivariate logistic models. Results: The sample consisted of 2247 persons with a new diagnosis of TIA, and 35% were admitted within one day of presentation. The mean age was 68, and 25% had a prior history of stroke or TIA. At one-year, 12.1% developed the composite outcome of stroke, myocardial infarction, and death. Older age, history of hypertension, atrial fibrillation, and diabetes were associated with admission (pTable ). Discussion: Persons admitted for TIA are more likely to possess stroke risk factors than those who were not admitted. The decision to admit was not associated with differences in one-year outcomes. Ongoing work will compare the completeness and timeliness of the diagnostic work-up of TIA as well as long-term control of stroke risk factors among persons admitted versus persons not admitted. Predictors of 1-year stroke, myocardial infarction, or death among persons with TIA Odds ratio [95% CI] p-value Hospital admission within one day 1.0 [0.8 - 1.4] 0.7 Age 1.0 [1.0 -1.0] History of hypertension 1.2 [0.9 - 1.7] 0.2 History of atrial fibrillation 1.5 [1.1 - 2.0] History of diabetes 1.2 [0.9 - 1.5] 0.3 History of stroke 1.8 [1.3 - 2.5] History of TIA 0.7 [0.5 - 1.1] 0.1 History of myocardial infarction 2.9 [1.3 - 6.1] |
