만성 뇌졸중 환자의 삶의 질에 영향을 미치는 요인

Abstract

Background: We investigated the factors that influence health-related quality of life in patients with chronicstroke. Methods: Ninety stroke patients, who had been discharged from hospital after inpatient rehabilitation 6months previously, responded telephone interview. We surveyed health-related quality of life by Medical OutcomeStudy 8-item Short Form Survey (SF-8). Current functional status was measured by the Korean Activities of DailyLiving (K-ADL) and the Korean Instrumental Activities of Daily Living (K-IADL). We also reviewed thesubjects’medical records to investigate medical comorbidities, cognitive impairments, depression etc. Results: 1)Mean scores of SF-8 were 41.01 for General Health (GH), 39.71 for Physical Functioning (PF), 37.46 for RolePhysical (RP), 48.92 for Bodily Pain (BP), 43.08 for Vitality (VT), 42.10 for Social Functioning (SF), 41.22 forRole Emotional (RE), and 42.22 for Mental Health (MH). 2) Current functional status measured by K-ADL andK-IADL had significant correlation with all items of SF-8. 3) Patients who had medical comorbodities, cognitivedeficits or depression showed significantly lower scores in some items of SF-8. 4) Interval between onset andadmission to rehabilitation unit showed inverse correlation to scores of PF, RP, BP, RE and MH, whereas thelength of stay did not. Patients who used day hospital program after discharge had significantly higher scores in allitems of SF-8.Conclusions: In chronic stroke patients, current functional status as well as medical comorbidities, cognitiveimpairment, depression affect health-related quality of life. Early start of inpatient rehabilitation and providingwith day hospital services after discharge may improve the quality of life after stroke.
