Abstract
- <bold>Background Context: </bold>Patients with comorbid disease may experience suboptimal quality of life (QOL) improvement following decompression spinal surgery. Prior studies have suggested the deleterious effect of diabetes upon postoperative QOL; however, these studies have not used minimal clinically important differences (MCIDs) or multivariable statistical techniques.<bold>Purpose: </bold>The purpose of this study was to assess the effect of preoperative diabetes upon postoperative change in QOL.<bold>Study Design/setting: </bold>A retrospective cohort study at a single tertiary-care center was carried out.<bold>Patient Sample: </bold>Patients who underwent lumbar decompression between 2008 and 2014 were included in the study. Inclusion necessitated a minimum follow-up of 6 months.<bold>Outcomes Measures: </bold>Postoperative changes in the EuroQol 5-Dimensions (EQ-5D), Pain Disability Questionnaire (PDQ), and Patient Health Questionnaire 9 (PHQ-9) at last follow-up were the primary outcome measures. The secondary outcome variable was postoperative change in QOL measures exceeding the MCID.<bold>Methods: </bold>Quality of life data were collected using the institutional prospectively collected database of patient-reported health status measures. Simple and multivariable logistic regressions were used to assess the impact of diabetes upon normalized change in QOL and improvement exceeding the MCID.<bold>Results: </bold>There were 212 patients who met inclusion criteria. Whereas non-diabetics experienced significant improvements in EQ-5D, PDQ, and PHQ-9 (p<.01), diabetics experienced no significant changes in any measures. More non-diabetics achieved the EQ-5D MCID compared with diabetics (55% vs. 23%, p<.01). Following multivariable regression, chronic kidney disease (CKD, β=-0.15, p=.04) and diabetes (β=-0.05, p=.04) were identified as significant independent predictors of diminished improvement in EQ-5D postoperatively. Furthermore, diabetes was also identified as a significant independent predictor of failure to achieve an EQ-5D MCID (OR 0.20, p<.01), whereas CKD trended toward predicting diminished improvement (OR<0.01, p=.09).<bold>Conclusion: </bold>The burden of comorbidities may impact the QOL benefit of decompression spine surgery. In the present study, diabetes was found to independently predict diminished improvement in QOL after lumbar decompression. [ABSTRACT FROM AUTHOR]
