    (Journal of neurosurgery. Spine, 2020-02) Bisson, Erica F; Mummaneni, Praveen V; Knightly, John; Alvi, Mohammed Ali; Goyal, Anshit; Chan, Andrew K; Guan, Jian; Biase, Michael; Strauss, Andrea; Glassman, Steven; Foley, Kevin; Slotkin, Jonathan R; Potts, Eric; Shaffrey, Mark; Shaffrey, Christopher I; Haid, Regis W; Fu, Kai-Ming; Wang, Michael Y; Park, Paul; Asher, Anthony L; Bydon, Mohamad
    OBJECTIVE:Loss to follow-up has been shown to bias outcomes assessment among studies utilizing clinical registries. Here, the authors analyzed patients enrolled in a national surgical registry and compared the baseline characteristics of patients captured with those lost to follow-up at 2 years. METHODS:The authors queried the Quality Outcomes Database for patients with grade I lumbar degenerative spondylolisthesis undergoing a surgical intervention between July 2014 and June 2016. Only those patients enrolled in a multisite study investigating the impact of fusion on clinical and patient-reported outcomes (PROs) among patients with grade I spondylolisthesis were evaluated. RESULTS:Of the 608 patients enrolled in the study undergoing 1- or 2-level decompression (23.0%, n = 140) or 1-level fusion (77.0%, n = 468), 14.5% (n = 88) were lost to follow-up at 2 years. Patients who were lost to follow-up were more likely to be younger (59.6 ± 13.5 vs 62.6 ± 11.7 years, p = 0.031), be employed (unemployment rate: 53.3% [n = 277] for successful follow-up vs 40.9% [n = 36] for those lost to follow-up, p = 0.017), have anxiety (26.1% [n = 23] vs 16.3% [n = 85], p = 0.026), have higher back pain scores (7.4 ± 2.9 vs 6.6 ± 2.8, p = 0.010), have higher leg pain scores (7.4 ± 2.5 vs 6.4 ± 2.9, p = 0.003), have higher Oswestry Disability Index scores (50.8 ± 18.7 vs 46 ± 16.8, p = 0.018), and have lower EQ-5D scores (0.481 ± 0.2 vs 0.547 ± 0.2, p = 0.012) at baseline. CONCLUSIONS:To execute future, high-quality studies, it is important to identify patients undergoing surgery for spondylolisthesis who might be lost to follow-up. In a large, prospective registry, the authors found that those lost to follow-up were more likely to be younger, be employed, have anxiety disorder, and have worse PRO scores.

    Identifying patients at risk for nonroutine discharge after surgery for cervical myelopathy: an analysis from the Quality Outcomes Database.
    (Journal of neurosurgery. Spine, 2021-05) Mummaneni, Praveen V; Bydon, Mohamad; Knightly, John J; Alvi, Mohammed Ali; Yolcu, Yagiz U; Chan, Andrew K; Foley, Kevin T; Slotkin, Jonathan R; Potts, Eric A; Shaffrey, Mark E; Shaffrey, Christopher I; Fu, Kai-Ming; Wang, Michael Y; Park, Paul; Upadhyaya, Cheerag D; Asher, Anthony L; Tumialan, Luis; Bisson, Erica F

    Objective

    Optimizing patient discharge after surgery has been shown to impact patient recovery and hospital/physician workflow and to reduce healthcare costs. In the current study, the authors sought to identify risk factors for nonroutine discharge after surgery for cervical myelopathy by using a national spine registry.

    Methods

    The Quality Outcomes Database cervical module was queried for patients who had undergone surgery for cervical myelopathy between 2016 and 2018. Nonroutine discharge was defined as discharge to postacute care (rehabilitation), nonacute care, or another acute care hospital. A multivariable logistic regression predictive model was created using an array of demographic, clinical, operative, and patient-reported outcome characteristics.

    Results

    Of the 1114 patients identified, 11.2% (n = 125) had a nonroutine discharge. On univariate analysis, patients with a nonroutine discharge were more likely to be older (age ≥ 65 years, 70.4% vs 35.8%, p < 0.001), African American (24.8% vs 13.9%, p = 0.007), and on Medicare (75.2% vs 35.1%, p < 0.001). Among the patients younger than 65 years of age, those who had a nonroutine discharge were more likely to be unemployed (70.3% vs 36.9%, p < 0.001). Overall, patients with a nonroutine discharge were more likely to present with a motor deficit (73.6% vs 58.7%, p = 0.001) and more likely to have nonindependent ambulation (50.4% vs 14.0%, p < 0.001) at presentation. On multivariable logistic regression, factors associated with higher odds of a nonroutine discharge included African American race (vs White, OR 2.76, 95% CI 1.38-5.51, p = 0.004), Medicare coverage (vs private insurance, OR 2.14, 95% CI 1.00-4.65, p = 0.04), nonindependent ambulation at presentation (OR 2.17, 95% CI 1.17-4.02, p = 0.01), baseline modified Japanese Orthopaedic Association severe myelopathy score (0-11 vs moderate 12-14, OR 2, 95% CI 1.07-3.73, p = 0.01), and posterior surgical approach (OR 11.6, 95% CI 2.12-48, p = 0.004). Factors associated with lower odds of a nonroutine discharge included fewer operated levels (1 vs 2-3 levels, OR 0.3, 95% CI 0.1-0.96, p = 0.009) and a higher quality of life at baseline (EQ-5D score, OR 0.43, 95% CI 0.25-0.73, p = 0.001). On predictor importance analysis, baseline quality of life (EQ-5D score) was identified as the most important predictor (Wald χ2 = 9.8, p = 0.001) of a nonroutine discharge; however, after grouping variables into distinct categories, socioeconomic and demographic characteristics (age, race, gender, insurance status, employment status) were identified as the most significant drivers of nonroutine discharge (28.4% of total predictor importance).

    Conclusions

    The study results indicate that socioeconomic and demographic characteristics including age, race, gender, insurance, and employment may be the most significant drivers of a nonroutine discharge after surgery for cervical myelopathy.

    Open versus minimally invasive decompression for low-grade spondylolisthesis: analysis from the Quality Outcomes Database.
    (Journal of neurosurgery. Spine, 2020-05) Bisson, Erica F; Mummaneni, Praveen V; Virk, Michael S; Knightly, John; Alvi, Mohammed Ali; Goyal, Anshit; Chan, Andrew K; Guan, Jian; Glassman, Steven; Foley, Kevin; Slotkin, Jonathan R; Potts, Eric A; Shaffrey, Mark E; Shaffrey, Christopher I; Haid, Regis W; Fu, Kai-Ming; Wang, Michael Y; Park, Paul; Asher, Anthony L; Bydon, Mohamad
    OBJECTIVE:Lumbar decompression without arthrodesis remains a potential treatment option for cases of low-grade spondylolisthesis (i.e., Meyerding grade I). Minimally invasive surgery (MIS) techniques have recently been increasingly used because of their touted benefits including lower operating time, blood loss, and length of stay. Herein, the authors analyzed patients enrolled in a national surgical registry and compared the baseline characteristics and postoperative clinical and patient-reported outcomes (PROs) between patients undergoing open versus MIS lumbar decompression. METHODS:The authors queried the Quality Outcomes Database for patients with grade I lumbar degenerative spondylolisthesis undergoing a surgical intervention between July 2014 and June 2016. Among more than 200 participating sites, the 12 with the highest enrollment of patients into the lumbar spine module came together to initiate a focused project to assess the impact of fusion on PROs in patients undergoing surgery for grade I lumbar spondylolisthesis. For the current study, only patients in this cohort from the 12 highest-enrolling sites who underwent a decompression alone were evaluated and classified as open or MIS (tubular decompression). Outcomes of interest included PROs at 2 years; perioperative outcomes such as blood loss and complications; and postoperative outcomes such as length of stay, discharge disposition, and reoperations. RESULTS:A total of 140 patients undergoing decompression were selected, of whom 71 (50.7%) underwent MIS and 69 (49.3%) underwent an open decompression. On univariate analysis, the authors observed no significant differences between the 2 groups in terms of PROs at 2-year follow-up, including back pain, leg pain, Oswestry Disability Index score, EQ-5D score, and patient satisfaction. On multivariable analysis, compared to MIS, open decompression was associated with higher satisfaction (OR 7.5, 95% CI 2.41-23.2, p = 0.0005). Patients undergoing MIS decompression had a significantly shorter length of stay compared to the open group (0.68 days [SD 1.18] vs 1.83 days [SD 1.618], p < 0.001). CONCLUSIONS:In this multiinstitutional prospective study, the authors found comparable PROs as well as clinical outcomes at 2 years between groups of patients undergoing open or MIS decompression for low-grade spondylolisthesis.
