Impact of a system-wide multicomponent intervention on administrative diagnostic coding for delirium and other cognitive frailty syndromes: observational prospective study.

Background: We determined the impact of a system-wide multicomponent intervention to improve recognition and documentation of cognitive frailty syndromes on hospital administrative coding for delirium.

Methods: A multicomponent intervention including introduction of structured patient assessment including cognitive/delirium screen, regular audit/feedback and educational seminars was undertaken (2012-17). Sensitivity and specificity of administrative , 10th revision (ICD-10) delirium codes for the gold standard of prospectively clinically diagnosed delirium were calculated in consecutive patients admitted to acute medicine over five 8-week cycles (2010-18).

Essen Risk Score in Prediction of Myocardial Infarction After Transient Ischemic Attack or Ischemic Stroke Without Prior Coronary Artery Disease.

Background and Purpose- More intensive secondary prevention with newer drugs may be cost-effective in patients with coronary artery disease (CAD). Whether some subgroups of patients who had a transient ischemic attack (TIA) or ischemic stroke, but no prior CAD are at similar high risk of myocardial infarction as those with prior CAD remains unclear. We determined whether the Essen score identified a subset of TIA/stroke patients without known prior CAD who, nevertheless, had a high risk of myocardial infarction on current secondary prevention management.

Effect of coexisting vascular disease on long-term risk of recurrent events after TIA or stroke.

Objective: To determine whether patients with TIA or ischemic stroke with coexisting cardiovascular disease (i.e., history of coronary or peripheral artery disease) are still at high risk of recurrent ischemic events despite current secondary prevention guidelines.

Prognostic value of "tissue-based" definitions of TIA and minor stroke: Population-based study.

Objective: Since use of diffusion-weighted imaging (DWI) positivity in the "tissue-based" definition of stroke in patients with a clinical TIA is supported by the high associated 90-day risk of recurrent stroke, we aimed to determine long-term prognostic significance, stratified by etiologic subtype, and whether the same tissue-based distinction is predictive in minor strokes.

Methods: Consecutive eligible patients with TIA or minor stroke (NIH Stroke Scale [NIHSS] ≤3) in the population-based Oxford Vascular Study underwent brain MRI at baseline. Stroke risk on 10-year follow-up was stratified by NIHSS (0/1 vs 2/3) and Trial of Org 10172 in Acute Stroke Treatment classification of the initial event.
