Study Design. Retrospective comparative study. Objective. The purpose of this study was to investigate whether preoperative depressive symptoms, measured by mental component score of the Short Form-12 survey (MCS-12), influence patient-reported outcome measurements (PROMs) following an anterior cervical discectomy and fusion (ACDF) surgery for cervical degeneration. Summary of Background Data. There is a paucity of literature regarding preoperative depression and PROMs following ACDF surgery for cervical degenerative disease. Methods. Patients who underwent an ACDF for degenerative cervical pathology were identified. A score of 45.6 on the MCS-12 was used as the threshold for depression symptoms, and patients were divided into two groups based on this value: depression (MCS-12 ≤45.6) and nondepression (MCS-12 >45.6) groups. Outcomes including Neck Disability Index (NDI), physical component score of the Short Form-12 survey (PCS-12), and Visual Analogue Scale Neck (VAS Neck), and Arm (VAS Arm) pain scores were evaluated using independent sample t test, recovery ratios, percentage of patients reaching the minimum clinically important difference, and multiple linear regression – controlling for factors such as age, sex, and BMI. Results. The depression group was found to have significantly worse baseline pain and disability than the nondepression group in NDI (P < 0.001), VAS Neck pain (P < 0.001), and VAS Arm pain (P < 0.001) scores. Postoperatively, both groups improved to a similar amount with surgery based on the recovery ratio analysis. The depression group continued to have worse scores than the nondepression group in NDI (P = 0.010), PCS-12 (P = 0.026), and VAS Arm pain (P = 0.001) scores. Depression was not a significant predictor of change in any PROMs based on regression analysis. Conclusion. Patients who presented with preoperative depression reported more pain and disability symptoms preoperatively and postoperatively; however, both groups achieved similar degrees of improvement. Level of Evidence: 3
Study Design. Retrospective cohort review. Objective. The objective of this study was to identify depression using the Mental Component Score (MCS-12) of the Short Form-12 (SF-12) survey and to correlate with patient outcomes. Summary of Background Data. The impact of preexisting depressive symptoms on health-care related quality of life (HRQOL) outcomes following lumbar spine fusion is not well understood. Methods. Patients undergoing lumbar fusion between one to three levels at a single center, academic hospital were retrospectively identified. Patients under the age of 18 years and those undergoing surgery for infection, trauma, tumor, or revision, and less than 1-year follow-up were excluded. Patients with depressive symptoms were identified using an existing clinical diagnosis or a score of MCS-12 less than or equal to 45.6 on the preoperative SF-12 survey. Absolute HRQOL scores, the recovery ratio (RR) and the percent of patients achieving minimum clinically important difference (MCID) between groups were compared, and a multiple linear regression analysis was performed. Results. A total of 391 patients were included in the total cohort, with 123 (31.5%) patients reporting symptoms of depression based on MCS-12 and 268 (68.5%) without these symptoms. The low MCS-12 group was found to have significantly worse preoperative Oswestry disability index (ODI), visual analogue scale back pain (VAS Back) and visual analogue scale leg pain (VAS Leg) scores, and postoperative SF-12 physical component score (PCS-12), ODI, VAS Back, and VAS Leg pain scores (P < 0.05) than the non-depressed group. Finally, multiple linear regression analysis revealed preoperative depression to be a significant predictor of worse outcomes after lumbar fusion. Conclusion. Patients with depressive symptoms, identified with an MCS-12 cutoff below 45.6, were found to have significantly greater disability in a variety of HRQOL domains at baseline and postoperative measurement, and demonstrated less improvement in all outcome domains included in the analysis compared with patients without depression. However, while the improvement was less, even the low MCS-12 cohort demonstrated statistically significant improvement in all HRQOL outcome measures after surgery. Level of Evidence: 3
The prestige of publication has been based on traditional citation metrics, most commonly journal impact factor. However, the Internet has radically changed the speed, flow, and sharing of medical information. Furthermore, the explosion of social media, along with development of popular professional and scientific websites and blogs, has led to the need for alternative metrics, known as altmetrics, to quantify the wider impact of research. We explore the evolution of current research impact metrics and examine the evolving role of altmetrics in measuring the wider impact of research. We suggest that altmetrics used in research evaluation should be part of an informed peer-review process such as traditional metrics. Moreover, results based on altmetrics must not lead to direct decision making about research, but instead, should be used to assist experts in making decisions. Finally, traditional and alternative metrics should complement, not replace, each other in the peer-review process.
Background: Pseudarthrosis following spinal fusion is a complication that frequently requires revision surgery. Reported rates of pseudarthrosis after surgical site infection (SSI) range from 30% to 85%, but few studies have identified infection as an independent risk factor for its development. The purpose of this study was to determine the incidence of clinically symptomatic pseudarthrosis in patient who developed SSI following lumbar fusion and to identify factors associated with its development. Methods: This was a retrospective review of a prospectively collected database. Patients who underwent spinal surgery and developed SSI between January 2005 and March 2015 with a minimum 2-year follow-up were included. Patient-specific and procedural characteristics were recorded. Presence of pseudarthrosis was determined clinically by the treating surgeon and was confirmed radiographically. All those in the Pseudarthrosis group required a revision procedure after the eradication of infection. Univariate and multivariate analyses were conducted as appropriate. Results: A total of 416 patients were included. Of these, 21 (5.0%) developed symptomatic pseudarthrosis following SSI. In this cohort, multivariate regression showed that age, Charlson Comorbidity Index, male sex, and surgical approach were not significant predictors of pseudarthrosis formation. However, number of levels fused was found to be the leading predictor for pseudarthrosis development (odds ratio [OR], 1.356/level, P , .001), followed by body mass index (OR, 1.083/point, P , .009) in this cohort. The number of levels fused was found to be a significant predictor of hardware removal (OR, 1.190/level, P , .001). Of the 21 pseudarthrosis cases, 85.7% found staphylococcal species, of which 27.8% exhibited methicillin-resistant Staphylococcus aureus. Conclusions: The number of spinal levels fused and body mass index are independent predictors of pseudarthrosis in patients who develop SSI after spinal fusion. Level of Evidence: Level 4 Clinical Relevance: This is the first known study to specifically identify risk factors for the development of symptomatic pseudarthrosis.
Study Design: This was a prospective cohort study. Objective: The objective of this study was to design and test a novel spine neurological examination adapted for telemedicine. Summary of Background Data: Telemedicine is a rapidly evolving technology associated with numerous potential benefits for health care, especially in the modern era of value-based care. To date, no studies have assessed whether. Methods: Twenty-one healthy controls and 20 patients with cervical or lumbar spinal disease (D) were prospectively enrolled. Each patient underwent a telemedicine neurological examination as well as a traditional in-person neurological examination administered by a fellowship trained spine surgeon and a physiatrist. Both the telemedicine and in-person tests consisted of motor, sensory, and special test components. Scores were compared via univariate analysis and secondary qualitative outcomes, including responses from a satisfaction survey, were obtained upon completion of the trial. Results: Of the 20 patients in the D group, 9 patients had cervical disease and 11 patients had lumbar disease. Comparing healthy control with the D group, there were no significant differences with respect to all motor scores, most sensory scores, and all special tests. There was a high rate of satisfaction among the cohort with 92.7% of participants feeling “very satisfied” with the overall experience. Conclusions: This study presents the development of a viable neurological spine examination adapted for telemedicine. The findings in this study suggest that patients have comparable motor, sensory, and special test scores with telemedicine as with a traditional in-person examination administered by an experienced clinician, as well as reporting a high rate of satisfaction among participants. To our knowledge, this is the first telemedicine neurological examination for spine surgery. Further studies are warranted to validate these findings.
Background: Currently, no studies have assessed what effect the presence of both anxiety and depression may have on patient-reported outcome measurements (PROMs) compared to patients with a single or no mental health diagnosis.Methods: Patients undergoing 1-to 3-level lumbar fusion at a single academic hospital were retrospectively queried. Anyone with depression and/or anxiety was identified using an existing clinical diagnosis in the medical chart. Patients were separated into 3 groups: no depression or anxiety (NDA), depression or anxiety alone (DOA), and combined depression and anxiety (DAA). Absolute PROMs, recovery ratios, and the percentage of patients achieving minimal clinically important difference (% MCID) between groups were compared using univariate and multivariate analysis.Results: Of the 391 patients included in the cohort, 323 (82.6%) were in the NDA group, 37 (9.5%) in the DOA group, and 31 (7.9%) in the DAA group. Patients in the DAA group had significantly worse outcome scores before and after surgery with respect to Short Form-12 mental component score (MCS-12) and Oswestry Disability Index (ODI) scores (P ,.001); however, the change in PROMs, recovery ratio, % MCID were not found to be significantly different between groups. Using multivariate analysis, the DAA group was found to be an independent predictor of worse improvement in MCS-12 and ODI scores (P ¼ .026 and P ¼ .001, respectively).Conclusions: Patients with combined anxiety and depression fared worse with respect to disability before and after surgery compared to patients with a single diagnosis or no mental health diagnosis; however, there were no significant differences in recovery ratio or % MCID.Level of Evidence: 3. Clinical Relevance: Combined anxiety and depression may predict less improvement in MCS-12 and ODI after lumbar arthrodesis compared with single or no mental health diagnosis.
