Risk of subsequent stroke not higher in patients receiving outpatient vs inpatient care for TIA: JAMA
![Risk of subsequent stroke not higher in patients receiving outpatient vs inpatient care for TIA: JAMA Risk of subsequent stroke not higher in patients receiving outpatient vs inpatient care for TIA: JAMA](https://medicaldialogues.in/h-upload/2022/01/06/750x450_167666-tia.webp)
USA: A recent study suggests that offering rapid management at transient ischemic attack (TIA) clinics is not inferior to inpatient care models. The study, published in JAMA Network Open compared the subsequent stroke risk at 2, 7, 30, and 90 days following a TIA or minor ischemic stroke (mIS).
The risk of subsequent stroke in patients evaluated in a TIA clinic was not higher than those hospitalized, the researchers stated. Patients who received treatment in emergency departments (ED) without any further follow-up were found to have a higher risk of subsequent stroke.
The transient ischemic attack is often an indicator of a high risk of subsequent cerebral ischemic events. Timely intervention is known to improve the outcome. Shima Shahjouei, Neurology Department, Neuroscience Institute, Geisinger Health System, Danville, Pennsylvania, and colleagues aimed to estimate and compare the risk of subsequent ischemic stroke among patients with TIA or mIS by care setting.
For this purpose, the researchers searched the online databases from the inception of each database until October 1, 2020. Studies that evaluated the occurrence of ischemic stroke after TIA or mIS were included.
The analysis included 226 683 patients from 71 articles recruited between 1981 and 2018; 5636 patients received care at TIA clinics, 130 139 as inpatients, 3605 at EDs, and 87 303 patients received care in an unspecified setting.
Based on the study, the researchers found the following:
- Among the patients who were treated at a TIA clinic, the risk of subsequent stroke following a TIA or mIS was 0.3% within 2 days, 1.0% within 7 days, 1.3% within 30 days, and 2.1% within 90 days.
- Among the patients who were treated as inpatients, the risk of subsequent stroke was to 0.5% within 2 days, 1.2% within 7 days, 1.6% within 30 days, and 2.8% within 90 days.
- The risk of stroke among patients treated at TIA clinics was not significantly different from those hospitalized.
- Compared with the inpatient cohort, TIA clinic patients were younger and had had lower ABCD2 (age, blood pressure, clinical features, duration of TIA, diabetes) scores (inpatients with ABCD2 score >3, 1101 of 1806 [61.0%]; TIA clinic patients with ABCD2 score >3, 1933 of 3703 [52.2%]).
"These findings suggest that TIA clinics can be an effective component of the TIA care component pathway," concluded the authors.
