Trends in treatment and outcome of stroke patients in Finland from 1999 to 2007. PERFECT Stroke, a nationwide register study

Abstract

Introduction: This article in this supplement issue on the Performance, Effectiveness, and Costs of Treatment episodes (PERFECT) project describes trends in Finnish stroke treatment and outcome. Material and Methods: The PERFECT Stroke study uses multiple national registry linkages at individual patient level to produce a national stroke database with comprehensive follow-up of all hospital-treated stroke patients in Finland. Results: There were 94,316 incident stroke patients treated in Finnish hospitals from 1999 to 2007. Lengths-of-stays decreased after ischemic stroke (IS), and increased after intracerebral (ICH) and subarachnoid (SAH) hemorrhage. Ten-year survival improved in IS (hazard ratio 0.75; 95% CI 0.71-0.79) and ICH patients (0.88; 0.79-0.97), increasing median survival by 2 and 1 life-years respectively. This has translated into more days spent home among IS patients, but not among ICH patients. Treatment by neurologists improved the survival of IS (odds ratio [OR] 1.77; 95% CI 1.70-1.84) and ICH patients (OR 1.55; 95% CI 1.40-1.69), and treatment by neurosurgeons of SAH patients (OR 2.66; 95% CI 2.25-3.16), the effects were further improved by care in specialized stroke centers. Discussion: The survival of Finnish IS and ICH patients has improved. Specialized acute care was associated with improved outcome. © 2011 Informa UK, Ltd.
