the Oswestry Disability Index version 2 1a validation of a dutch language version
Spine, 2015Co-Authors: Miranda L Van Hooff, Jeremy Fairbank, M Spruit, Jacques Van Limbeek, Wilco C H JacobsAbstract:STUDY DESIGN: A cross-sectional study on baseline data. OBJECTIVE: To translate the Oswestry Disability Index (ODI) version 2.1a into the Dutch language and to validate its use in a cohort of patients with chronic low back pain in secondary spine care. SUMMARY OF BACKGROUND DATA: Patient-reported outcome measures (PROMs) are commonly accepted to evaluate the outcome of spine interventions. Functional status is an important outcome in spine research. The ODI is a recommended condition-specific patient-reported outcome measure used to evaluate functional status in patients with back pain. As yet, no formal translated Dutch version exists. METHODS: The ODI was translated according to established guidelines. The final version was built into the electronic web-based system in addition with the Roland Morris Disability Questionnaire, the numeric rating scale for pain severity, 36-Item Short Form Health Survey Questionnaire for quality of life, and the hospital anxiety and depression scale. Baseline data were used of 244 patients with chronic low back pain who participated in a combined physical and psychological program. Floor and ceiling effects, internal consistency, and the construct validity were evaluated using quality criteria. RESULTS: The mean ODI (standard deviation) was 39.6 (12.3); minimum 6, maximum 70. Most of the participants (88%) were moderately to severely disabled. Factor analysis determined a 1-factor structure (36% explained variance) and the homogeneity of ODI items is shown (Cronbach α = 0.79). The construct validity is supported as all (6:6) the a priori hypotheses were confirmed. Moreover, the ODI and Roland Morris Disability Questionnaire, showed a strong significant correlation (r = 0.68, P < 0.001) and an overlap: mean difference of -18 (95% limits of agreement: -44 to 8). CONCLUSION: The Dutch ODI version 2.1a is a valid and valuable tool for the measurement of functional status and Disability among Dutch patients with chronic low back pain. This translated condition-specific patient-reported outcome measure version is recommended for use in future back pain research and to evaluate outcome of back care in the Netherlands.

why are there different versions of the Oswestry Disability Index
Journal of Neurosurgery, 2014Co-Authors: Jeremy FairbankAbstract:This article updates readers on the current state of the Oswestry Disability Index (ODI) and the impact of unvalidated versions. The ODI is now licensed to the Mapi Research Trust in order to preserve a standard version in English and in validated translations. A proposed threshold of “normality” is potentially helpful as an outcome for both audit and research. There is an application of the sex section as a quality measure in Germany. The ODI is an important international shared resource for clinicians and investigators and should not be abused. Its current status will not be enhanced by further modification. It is now registered with the International Consortium for Health Outcomes Measurement as a standard outcome measure.

reliability and validity study on the hungarian versions of the Oswestry Disability Index and the quebec back pain Disability scale
European Spine Journal, 2013Co-Authors: Tamas Valasek, Jeremy Fairbank, Peter Paul Varga, Zsolt Szoverfi, Michelle Kumin, Aron LazaryAbstract:Purpose Patient-reported outcome measurements (PROMs) are widely used in spine care. The development of reliable and valid National versions of spine-related Disability questionnaires is strongly recommended from both the clinical and scientific points-of-view. The aims of this study were to adapt and validate the Oswestry Disability Index (ODI) and the Quebec Back Pain Disability Scale (QDS) for use with the Hungarian language.

development of a german version of the Oswestry Disability Index part 1 cross cultural adaptation reliability and validity
European Spine Journal, 2006Co-Authors: Anne F. Mannion, Jeremy Fairbank, Astrid Junge, Jiri Dvorak, Dieter GrobAbstract:Patient-orientated assessment methods are of paramount importance in the evaluation of treatment outcome. The Oswestry Disability Index (ODI) is one of the condition-specific questionnaires recommended for use with back pain patients. To date, no German version has been published in the peer-reviewed literature. A cross-cultural adaptation of the ODI for the German language was carried out, according to established guidelines. One hundred patients with chronic low-back pain (35 conservative, 65 surgical) completed a questionnaire booklet containing the newly translated ODI, along with a 0–10 pain visual analogue scale (VAS), the Roland Morris Disability Questionnaire, and Likert scales for Disability, medication intake and pain frequency [to assess ODI’s construct (convergent) validity]. Thirty-nine of these patients completed a second questionnaire within 2 weeks (to assess test–retest reliability). The intraclass correlation coefficient for the test–retest reliability of the questionnaire was 0.96. In test–retest, 74% of the individual questions were answered identically, and 21% just one grade higher or lower. The standard error of measurement (SEM) was 3.4, giving a “minimum detectable change” (MDC95%) for the ODI of approximately 9 points, i.e. the minimum change in an individual’s score required to be considered “real change” (with 95% confidence) over and above measurement error. The ODI scores correlated with VAS pain intensity (r=0.78, P<0.001) and Roland Morris scores (r=0.80, P<0.001). The mean baseline ODI scores differed significantly between the surgical and conservative patients (P<0.001), and between the different categories of the Likert scales for Disability, medication use and pain frequency (in each case P<0.001). Our German version of the Oswestry questionnaire is reliable and valid, and shows psychometric characteristics as good as, if not better than, the original English version. It should represent a valuable tool for use in future patient-orientated outcome studies in German-speaking lands.

development of a german version of the Oswestry Disability Index part 2 sensitivity to change after spinal surgery
European Spine Journal, 2006Co-Authors: Anne F. Mannion, Astrid Junge, Jiri Dvorak, Dieter Grob, Jeremy FairbankAbstract:When functional scales are to be used as treatment outcome measures, it is essential to know how responsive they are to clinical change. This information is essential not only for clinical decision-making, but also for the determination of sample size in clinical trials. The present study examined the responsiveness of a German version of the Oswestry Disability Index version 2.1 (ODI) after surgical treatment for low back pain. Before spine surgery 63 patients completed a questionnaire booklet containing the ODI, along with a 0–10 pain visual analogue scale (VAS), the Roland Morris Disability questionnaire, and Likert scales for Disability, medication intake and pain frequency. Six months after surgery, 57 (90%) patients completed the same questionnaire booklet and also answered Likert-scale questions on the global result of surgery, and on improvements in pain and Disability. Both the effect size for the ODI change score 6 months after surgery (0.87) and the area under the receiver operating characteristics (ROC) curve for the relative improvement in ODI score in relation to global outcome 6 months after surgery (0.90) indicated that the ODI showed good responsiveness. The ROC method revealed that a minimum reduction of the baseline (pre-surgery) ODI score by 18% (equal to a mean 8-point reduction in this patient group) represented the cut-off for indicating a “good” individual outcome 6 months after surgery (sensitivity 91.4% and specificity 82.4%). The German version of the ODI is a sensitive instrument for detecting clinical change after spinal surgery. Individual improvements after surgery of at least an 18% reduction on baseline values are associated with a good outcome. This figure can be used as a reliable guide for the determination of sample size in future clinical trials of spinal surgery.

should the euroqol five dimensions replace the Oswestry Disability Index when tracking lumbar tubular microdecompression outcomes
World Neurosurgery, 2020Co-Authors: Ziyad O Knio, Trent Vanhorn, Tadhg J OgaraAbstract:Objective Patient-reported outcomes measures (PROMs) are critical in evaluating the effectiveness of surgical spine interventions. The Oswestry Disability Index (ODI) is commonly used but tedious to administer routinely. The EuroQol-5 Dimensions (EQ-5D) questionnaire is easier to administer but not traditionally used to measure spine surgical results. This study aimed to investigate the correlation of commonly administered PROMs in lumbar tubular microdecompression patients, and to consider whether ODI could be predicted from remaining PROMs. Methods This study examined 304 Index lumbar tubular microdecompression patients with PROMs collected at routine intervals. Spearman correlation coefficients were calculated for each pairwise combination of the following PROMs: ODI, EQ-5D Index, leg pain visual analog scale (VAS), low back pain VAS, health state item. Linear regression modeling was conducted to predict ODI from the remaining four PROMs. Results The patients had a mean age of 65.55 ± 12.97 years and 46.4% were male. Each combination of PROMs demonstrated a statistically significant pairwise correlation (P Conclusions ODI can be predicted from EQ-5D, leg and low back pain VAS, and health state items with moderate accuracy. The added utility of capturing ODI routinely may not out-weigh the challenges in doing so.

Should the EuroQol-Five Dimensions Replace the Oswestry Disability Index When Tracking Lumbar Tubular Microdecompression Outcomes?
World neurosurgery, 2019Co-Authors: Ziyad O Knio, Trent Vanhorn, Tadhg J O'garaAbstract:Patient-reported outcomes measures (PROMs) are critical in evaluating the effectiveness of surgical spine interventions.

Each combination of PROMs demonstrated a statistically significant pairwise correlation (P < 0.001). ODI showed strong correlation with EQ-5D Index (r = -0.77), leg pain VAS (r = 0.73), and back pain VAS (r = 0.65), but weak correlation with health state item (r = -0.33). Forwards stepwise model selection yielded a multiple linear regression model including all four PROMs predictors, with an adjusted R2 of 0.690. There was strong correlation between predicted and observed ODI (r = 0.83, P < 0.001). ODI can be predicted from EQ-5D, leg and low back pain VAS, and health state items with moderate accuracy. The added utility of capturing ODI routinely may not out-weigh the challenges in doing so. Copyright © 2019 Elsevier Inc. All rights reserved.

inadequacy of 3 month Oswestry Disability Index outcome for assessing individual longer term patient experience after lumbar spine surgery
Journal of Neurosurgery, 2016Co-Authors: Anthony L Asher, Silky Chotai, Clinton J Devin, Theodore Speroff, Frank E Harrell, Hui Nian, Robert S Dittus, Praveen V Mummaneni, John J Knightly, Steven D GlassmanAbstract:OBJECTIVE Prospective longitudinal outcomes registries are at the center of evidence-driven health care reform. Obtaining real-world outcomes data at 12 months can be costly and challenging. In the present study, the authors analyzed whether 3-month outcome measurements sufficiently represent 12-month outcomes for patients with degenerative lumbar disease undergoing surgery. METHODS Data from 3073 patients undergoing elective spine surgery for degenerative lumbar disease were entered into a prospective multicenter registry (N2QOD). Baseline, 3-month, and 12-month follow-up Oswestry Disability Index (ODI) scores were recorded. The absolute differences between actual 12- and 3-month ODI scores was evaluated. Additionally, the authors analyzed the absolute difference between actual 12-month ODI scores and a model-predicted 12-month ODI score (the model used patients' baseline characteristics and actual 3-month scores). The minimal clinically important difference (MCID) for ODI of 12.8 points and the substant...

clinically important deterioration in patients undergoing lumbar spine surgery a choice of evaluation methods using the Oswestry Disability Index 36 item short form health survey and pain scales clinical article
Journal of Neurosurgery, 2013Co-Authors: Steven D Glassman, Leah Y CarreonAbstract:Object Health-related quality of life (HRQOL) measures have become the mainstay for outcome appraisal in spine surgery. Clinically meaningful interpretation of HRQOL improvement has centered on the minimum clinically important difference (MCID). The purpose of this study was to calculate clinically important deterioration (CIDET) thresholds and determine a CIDET value for each HRQOL measure for patients undergoing lumbar fusion. Methods Seven hundred twenty-two patients (248 males, 127 smokers, mean age 60.8 years) were identified with complete preoperative and 1-year postoperative HRQOLs including the Oswestry Disability Index (ODI), 36-Item Short Form Health Survey (SF-36), and numeric rating scales (0–10) for back and leg pain following primary, instrumented, posterior lumbar fusion. Anchor-based and distribution-based methods were used to calculate CIDET for each HRQOL. Anchor-based methods included change score, change difference, and receiver operating characteristic curve analysis. The Health Trans...

predictors of Oswestry Disability Index worsening after lumbar fusion
Orthopedics, 2013Co-Authors: Leah Y Carreon, Jeffrey D Stimac, Steven D GlassmanAbstract:: The authors identified patients with an increase in their Oswestry Disability Index (ODI) score after lumbar spine fusion to evaluate whether this is a plausible definition of deterioration and to determine whether any common patient characteristics exist.A total of 1054 patients who underwent lumbar spinal fusion and had 2-year follow-up data, including the Short Form 36, the ODI, and numeric rating scales for back and leg pain, were identified. Patients with worsening ODI were compared with the remaining cohort. Twenty-eight patients had an absolute increase (worse) in ODI at 1 year postoperatively. Participants with worsening ODI scores included 13 men and 15 women with an average age of 43.3 years; 15 (54%) were smokers. Common medical comorbidities included obesity and hypertension. Complications occurred in 5 (18%) patients and included wound infection, dural tear, and nerve root injury. Pseudarthrosis was common (n=8; 28%). Twenty-one patients required an additional intervention, including epidural injections, fusion revision, and cervical spine surgery.It is important to have a clear definition of deterioration to better provide informed consent or choice of treatment. Only 28 (2.6%) patients were identified as having an increase in ODI score at 2-year follow-up.

changes in the Oswestry Disability Index that predict improvement after lumbar fusion
Journal of Neurosurgery, 2012Co-Authors: Mladen Djurasovic, Steven D Glassman, John R Dimar, Charles H Crawford, Kelly R Bratcher, Leah Y CarreonAbstract:Object Clinical studies use both disease-specific and generic health outcomes measures. Disease-specific measures focus on health domains most relevant to the clinical population, while generic measures assess overall health-related quality of life. There is little information about which domains of the Oswestry Disability Index (ODI) are most important in determining improvement in overall health-related quality of life, as measured by the 36-Item Short Form Health Survey (SF-36), after lumbar spinal fusion. The objective of the study is to determine which clinical elements assessed by the ODI most influence improvement of overall health-related quality of life. Methods A single tertiary spine center database was used to identify patients undergoing lumbar fusion for standard degenerative indications. Patients with complete preoperative and 2-year outcomes measures were included. Pearson correlation was used to assess the relationship between improvement in each item of the ODI with improvement in the SF...

Oswestry Disability Index: Is Telephone Administration Valid?
The Iowa orthopaedic journal, 2020Co-Authors: Christopher Martin, Alexandra K. Yaszemski, Charles Gerald T. Ledonio, Tara C. Barrack, David W. PollyAbstract:Background The Oswestry Disability Index (ODI) is among the most widely used patient reported outcome measures for the assessment of spinal conditions. Traditionally, the ODI has been administered in outpatient clinics on a face-to-face basis, which can be expensive and time consuming. Furthermore, the percentage of patients lost to clinical follow-up is high, particularly after 2-5 years. Thus, telephonic administration of the ODI, if valid, could be a convenient way of capturing patient outcomes and increasing follow-up rates. The objective of this study was to validate telephonic administration of the ODI compared to face-to-face administration. Methods A convenience sample of individuals with and without back pain in an academic medical center were recruited for this study. Face-to-face administration of the ODI was completed and retested 24 hours later via phone. Test-retest reliability was determined by calculating the intraclass correlation coefficient. Results 22 individuals completed the ODI questionnaire face-to-face, then via telephone 24 hours later. There was a mean 2% (± 3) intra-rater ODI score difference (range: 0% to 12%). The intraclass correlation coefficient overall was 0.98 (95% CI: 0.96, 0.99, p

The intraclass correlation coefficient overall was 0.98 (95% CI: 0.96, 0.99, p<0.001) with a range of 0.95 to 1.0, revealing near-perfect test-retest reliability. Conclusions Administration of the ODI questionnaire over the phone has excellent test-retest reliability when compared to face-to-face administration. Telephone administration is a convenient and reliable option for obtaining follow-up outcomes data. Clinical Relevance Telephonic administration of the ODI is scientifically valid, and should be an accepted method of data collection for state-level and national-level outcomes projects.
