PurposeThe admission due to low back pain (LBP) became prevalent cause of international economic losses. Since LBP patients with disability are often subject to inpatient care, it is important to determine the appropriate time of discharge. The purpose of this study is to set the cut-off value of appropriate Oswestry Disability Index (ODI) at the time of discharge.MethodsOf 1,394 LBP patients admitted in hospital specialized in spinal disease, 774 eligible patients with disability were included in this study. And several clinical variables including numerical rating score, ODI, satisfaction level were observed during the hospital stay. We considered satisfaction level as an important factor for discharge, categorized patients into satisfied group and dissatisfied group. Through the statistical analysis, appropriate factor for determining dischargeable patients satisfied with their current condition and its cut-off value of ODI were found. And proper predictors for the cut-off value were extracted statistically and logically from a pool of several clinical indexes.ResultsThe ODI at the time of discharge was most accurate in determining dischargeable patients. The cut-off value of ODI was 30. Predictors were ODI questions 4 and 6.ConclusionWe set the cut-off value of dischargeable ODI for LBP inpatient with disability and found its predictor.
