J Clin Neurosci 2024; 121:23-27. [PMID: 38335824 DOI: 10.1016/j.jocn.2024.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 02/01/2024] [Indexed: 02/12/2024]
Abstract
The influence of Charlson Comorbidity Index (CCI) burden on Patient-Reported Outcomes Measurement Information System (PROMIS) outcomes following lumbar decompression (LD) is limited. The objective of this study is to evaluate CCI burden impact on PROMIS outcomes. Retrospective review of elective LD excluding revision or surgeries for infectious, malignant, or traumatic reasons. Demographics and PROMIS scores collected preoperatively and postoperatively up to 2 years included: PROMIS-Physical Function (PF)/Sleep Disturbance (SD)/Pain Interference (PI)/Anxiety (A), VR-12 Physical/Mental Health Composite scores (VR-12 PCS/MCS)/Oswestry Disability Index (ODI). Patients were divided into two groups based on their preoperative CCI score <3 (mild) or ≥4 (moderate to severe). Descriptive statistical analysis and MCID achievement rate calculations were conducted. A total of 182 patients were included: 93 CCI < 3 and 88 CCI ≥ 4. No significant differences were reported across preoperative PROMIS/legacy PROMs or final follow-up (p > 0.05, all). At 6-weeks, VR-12 PCS and ΔPROM scores indicated improved physician function in the CCI < 3 group (p = 0.020 and p = 0.040, respectively). Significant PROMIS-A ΔPROM score at final post-op was noted for CCI < 3 group (p = 0.026). MCID achievement demonstrated no significant differences for PROMIS outcomes and legacy PROMs. Results demonstrated that PROMIS outcomes were not impacted by a greater baseline comorbidity burden. At 6-weeks, the physical function scores were improved for the lower CCI group, and at final reported less anxiety. Our data suggests that comorbidity burden has a limited effect on PROMIS and legacy outcomes in patients undergoing LD.

[PMID: 37793148 DOI: 10.5435/jaaos-d-23-00297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 08/21/2023] [Indexed: 10/06/2023] Open
Abstract
INTRODUCTION The purpose of this study was to evaluate the ability of the Pathologic Fracture Mortality Index (PFMI) to predict the risk of 30-day morbidity after pathologic fracture fixation and compare its efficacy with those of the American Society of Anesthesiologists (ASA) physical status, modified Charlson Comorbidity Index (mCCI), and modified frailty index (mFI-5). METHODS Cohorts of 1,723 patients in the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2020 and 159 patients from a tertiary cancer referral center who underwent fixation for impending or completed pathologic fractures of long bones were retrospectively analyzed. National Surgical Quality Improvement Program morbidity variables were categorized into medical, surgical, utilization, and all-cause. PFMI, ASA, mCCI, and mFI-5 scores were calculated for each patient. Area under the curve (AUC) was used to compare efficacies. RESULTS AUCs predicting all-cause morbidity were 0.62, 0.54, and 0.56 for the PFMI, ASA, and mFI-5, respectively. The PFMI outperformed the ASA and mFI-5 in predicting all-cause ( P < 0.01), medical ( P = 0.01), and utilization ( P < 0.01) morbidities. In the 2005 to 2012 subset, the PFMI outperformed the ASA, mFI-5, and mCCI in predicting all-cause ( P = 0.01), medical ( P = 0.03), and surgical ( P = 0.05) morbidities but performed similarly to utilization morbidity ( P = 0.19). In our institutional cohort, the AUC for the PFMI in morbidity stratification was 0.68. The PFMI was associated with all-cause (odds ratio [OR], 1.30; 95% confidence interval [CI], 1.12 to 1.51; P < 0.001), medical (OR, 1.19; 95% CI, 1.03 to 1.40; P = 0.046), and utilization (OR, 1.32; 95% CI, 1.14 to 1.52; P < 0.001) morbidities but not significantly associated with surgical morbidity (OR, 1.21; 95% CI, 0.98 to 1.49; P = 0.08) in this cohort. DISCUSSION The PFMI is an advancement in postoperative morbidity risk stratification of patients with pathologic fracture from metastatic disease. LEVEL OF EVIDENCE III.

World Neurosurg 2023; 179:e39-e45. [PMID: 37356480 DOI: 10.1016/j.wneu.2023.06.082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 06/16/2023] [Accepted: 06/17/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Metastatic spinal tumors represent 90% of spinal masses and present variably with slow progression and/or rapid symptomatic worsening. Several prognostic scoring systems have been proposed. However, patients presenting acutely and requiring emergent surgery represent a unique subset of patients with different prognostic indicators. METHODS All cases of symptomatic spinal metastases requiring emergent surgery between 2010 and 2021 at our institution were retrospectively reviewed. Survival time from date of surgery to death or last follow-up was calculated. Patients were stratified on the basis of survival for more or less than 6 months after surgery. Multivariate logistic regression was used to develop a model predicting probability of mortality at 6 months. RESULTS Forty-four patients satisfied inclusion criteria. Mean age at presentation was 60.4 ± 11.8 years with a median survival time of 6.5 [1.9-19.5 interquartile range] months. On univariate analysis, higher Tokuhashi score, Karnofksy performance scale (KPS), and lower modified McCormick scale were significantly associated with 6-month survival (P = 0.018, P < 0.001, P = 0.002, respectively). Preoperative American Spinal Injury Association grade and Spine Instability Neoplastic Score scores were not associated with survival. Multivariate analysis found KPS significantly correlated with survival (0.91 odds ratio, 0.85-0.98, 95% confidence interval, P = 0.011) at 6 months and that a stepwise regression model derived from KPS and Tokuhashi score demonstrated the highest predictive accuracy for 6-month survival (area under the curve = 0.843, Akaike information criterion = 37.1, P = 0.0039). CONCLUSIONS KPS and Tokuhashi scores most strongly correlated with 6-month survival in patients presenting with acutely symptomatic spinal metastases. These findings underscore the importance of baseline functional status and overall tumor burden on survival and may be useful in preoperative evaluation and surgical decision making for acutely presenting spinal metastases.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE Physicians may be deterred from operating on elderly patients due to fears of poorer outcomes and complications. We aimed to compare the outcomes of surgical treatment of spinal metastases patients aged ≥70-yrs and <70-yrs. MATERIALS AND METHODS This is a retrospective study of patients surgically treated for metastatic epidural spinal cord compression and spinal instability between January-2005 to December-2021. Follow-up was till death or minimum 1-year post-surgery. Outcomes included post-operative neurological status, ambulatory status, medical and surgical complications. Two Sample t-test/Mann Whitney U test were used for numerical variables and Pearson Chi-Squared or Fishers Exact test for categorical variables. Survival was presented with a Kaplan-Meier curve. P < .05 was significant. RESULTS We identified 412 patients of which 29 (7.1%) patients were excluded due to loss to follow-up and previous surgical treatment. 79 (20.6%) were ≥70-yrs. Age ≥70-yrs patients had poorer ECOG scores (P = .0017) and Charlson Comorbidity Index (P < .001). No significant difference in modified Tokuhashi score (P = .393) was observed with significantly more ≥ prostate (P < .001) and liver (P = .029) cancer in ≥70-yrs. Improved or maintained normal neurological function (P = .934), independent ambulatory status (P = .171), and survival at 6 months (P = .119) and 12 months (P = .659) was not significantly different between both groups. Medical (P = .528) or surgical (P = .466) complication rates and readmission rates (P = .800) were similar. CONCLUSION ≥70-yrs patients have comparable outcomes to <70-yr old patients with no significant increase in complication rates. Age should not be a determining factor in deciding surgical management of spinal metastases.

Previous Emergency Department Admission Is Associated With Increased 90-Day Readmission Following Cervical Spine Surgery: Evidenced Using Propensity Score Matching. Clin Spine Surg 2023; 36:E198-E205.

Abstract
STUDY DESIGN This was a retrospective case-control study. OBJECTIVE The objective of this study was to evaluate whether prior emergency department admission was associated with an increased risk for 90-day readmission following elective cervical spinal fusion. SUMMARY OF BACKGROUND DATA The incidence of cervical spine fusion reoperations has increased, necessitating the improvement of patient outcomes following surgery. Currently, there are no studies assessing the impact of emergency department visits before surgery on the risk of 90-day readmission following elective cervical spine surgery. This study aimed to fill this gap and identify a novel risk factor for readmission following elective cervical fusion. METHODS The 2016-2018 Nationwide Readmissions Database was queried for patients aged 18 years and older who underwent an elective cervical fusion. Prior emergency admissions were defined using the variable HCUP_ED in the Nationwide Readmissions Database database. Univariate analysis of patient demographic details, comorbidities, discharge disposition, and perioperative complication was evaluated using a χ 2 test followed by multivariate logistic regression. RESULTS In all, 2766 patients fit the inclusion criteria, and 18.62% of patients were readmitted within 90 days. Intraoperative complications, gastrointestinal complications, valvular, uncomplicated hypertension, peripheral vascular disorders, chronic obstructive pulmonary disease, cancer, and experiencing less than 3 Charlson comorbidities were identified as independent predictors of 90-day readmission. Patients with greater than 3 Charlson comorbidities (OR=0.04, 95% CI 0.01-0.12, P <0.001) and neurological complications (OR=0.29, 95% CI 0.10-0.86, P =0.026) had decreased odds for 90-day readmission. Importantly, previous emergency department visits within the calendar year before surgery were a new independent predictor of 90-day readmission (OR=9.74, 95% CI 6.86-13.83, P <0.001). CONCLUSIONS A positive association exists between emergency department admission history and 90-day readmission following elective cervical fusion. Screening cervical fusion patients for this history and optimizing outcomes in those patients may reduce 90-day readmission rates.

Abstract
PURPOSE Spinal metastasis surgeries carry substantial risk of complications. PRF is among complications that significantly increase mortality rate and length of hospital stay. The risk factor of PRF after spinal metastasis surgery has not been investigated. This study aims to identify the predictors of postoperative respiratory failure (PRF) and in-hospital death after spinal metastasis surgery. METHODS We retrospectively reviewed consecutive patients with spinal metastasis surgically treated between 2008 and 2018. PRF was defined as mechanical ventilator dependence > 48 h postoperatively (MVD) or unplanned postoperative intubation (UPI). Collected data include demographics, laboratory data, radiographic and operative data, and postoperative complications. Stepwise logistic regression analysis was used to determine predictors independently associated with PRFs and in-hospital death. RESULTS This study included 236 patients (average age 57 ± 14 years, 126 males). MVD and UPI occurred in 13 (5.5%) patients and 13 (5.5%) patients, respectively. During admission, 14 (5.9%) patients had died postoperatively. Multivariate logistic regression analysis revealed significant predictors of MVD included intraoperative blood loss > 2000 mL (odds ratio [OR] 12.28, 95% confidence interval [CI] 2.88-52.36), surgery involving cervical spine (OR 9.58, 95% CI 1.94-47.25), and ASA classification ≥ 4 (OR 6.59, 95% CI 1.85-23.42). The predictive factors of UPI included postoperative sepsis (OR 20.48, 95% CI 3.47-120.86), central nervous system (CNS) metastasis (OR 10.21, 95% CI 1.42-73.18), lung metastasis (OR 7.18, 95% CI 1.09-47.4), and postoperative pulmonary complications (OR 6.85, 95% CI 1.44-32.52). The predictive factors of in-hospital death included postoperative sepsis (OR 13.15, 95% CI 2.92-59.26), CNS metastasis (OR 10.55, 95% CI 1.54-72.05), and postoperative pulmonary complications (OR 9.87, 95% CI 2.35-41.45). CONCLUSION PRFs and in-hospital death are not uncommon after spinal metastasis surgery. Predictive factors for PRFs included preoperative comorbidities, intraoperative massive blood loss, and postoperative complications. Identification of risk factors may help guide therapeutic decision-making and patient counseling.

Abstract
BACKGROUND Infectious Spondylodiscitis is a heterogeneous disease usually affecting a fragile patient population with multiple comorbidities. Therefore, surgical and medical complications are important considerations before initiating treatment. METHODS This retrospective analysis included data of 218 patients who underwent surgical treatment for pyogenic Spondylodiscitis between 2008 and 2016. Groups were divided into length of hospital stay (LOS) (group I ≤21 days and group II>21 days). Analysis included patient age, gender, Charlson comorbidity index, smoking, obesity, osteoporosis, colonization with multidrug-resistant bacteria, preoperative neurologic deficit, pre- and postoperative inflammation markers (CRP and WBC), duration of surgery, number of operated segments, vertebrectomy, and postoperative medical and surgical complications. The case value for each patient expressed in Euro was retrieved from hospital records and included in the analysis. RESULTS Duration of stay after surgical treatment of Spondylodiscitis was ≤21 days (range: 4-21 days; mean: 16 days) in 41% of patients and >21 days (range: 22-162 days; mean: 41 days) in 59% of the patients. Multivariate analysis showed that both medical complications (odds ratio [OR]: 2.62; 95% confidence interval [CI]: 1.24-5.56; p=0.012) and surgical site infection (OR: 6.04; 95% CI: 2.35-15.51; p<0.001) were independently associated with a long hospital stay. Case values averaged at €21,667±1,579 (minimum: €2,888; maximum: €203,802) and correlated significantly with the length of hospital stay (Pearson's correlation coefficient: 0.681; p<0.05). The occurrence of a postoperative complication increased the cost of care significantly from €17,790 to 24,527 on average (p=0.025). CONCLUSIONS This study provides benchmark data for patients treated surgically for Spondylodiscitis. Surgical site infection and medical complications are the main drivers of prolonged hospital stays and cost of care.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVES Although the role of surgery in the management of metastatic spinal cord compression (MSCC) has been well established, elderly patients may still be denied surgery because of higher risk of complications and shorter life expectancy. The purpose of this study was to determine whether elderly patients with MSCC could benefit from surgery and discuss the criteria for surgical decision-making in such patients. METHODS Enrolled in this study were 55 consecutive patients aged 75 years or older who were surgically treated for MSCC in our center. Prognostic factors predicting overall survival (OS) were explored by the Kaplan-Meier method and Cox regression model. The quality of life (QoL) of the patients was evaluated by the SOSGOQ and compared using Student's t test. Risk factors for postoperative complications were identified by Chi-square test and multiple logistic regression analysis. RESULTS Surgical treatment for MSCC substantially improved the neurological function in 55.8% patients and QoL in 88.5% patients with acceptable rates of postoperative complications (16.4%), reoperation (9.1%), and 30-day mortality (1.8%). Postoperative ECOG-PS of 1-2, total en-bloc spondylectomy (TES), and postoperative chemotherapy were favorable prognostic factors for OS, while a high Charlson Comorbidity Index (CCI) and a long operation time were risk factors for postoperative complications. CONCLUSIONS Surgery should be encouraged for elderly patients with MSCC 1) who are compromised by the current or potential neurological dysfunction; 2) with radioresistant tumors; 3) with spinal instability; and 4) with no comorbidity, ECOG-PS of 0-2, and systemic treatment adherence. In addition, surgery should be performed by a skilled and experienced surgical team.

Perioperative risk stratification of spine trauma patients with ankylosing spinal disorders: a comparison of 3 quantitative indices. J Neurosurg Spine 2022; 37:722-728.

Abstract
OBJECTIVE Patients with ankylosing spinal disorders (ASDs), including ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH), have been shown to experience significantly increased rates of postoperative complications. Despite this, very few risk stratification tools have been validated for this population. As such, the purpose of this study was to identify predictors of adverse events and mortality in ASD patients undergoing surgery for 3-column fractures. METHODS All adult patients with a documented history of AS or DISH who underwent surgery for a traumatic 3-column fracture between 2000 and 2020 were identified. Perioperative variables, including comorbidities, time to diagnosis, and number of fused segments, were collected. Three instruments, including the Charlson Comorbidity Index (CCI), modified frailty index (mFI), and Injury Severity Score (ISS), were computed for each patient. The primary outcomes of interest included 1-year mortality, as well as postoperative complications. RESULTS A total of 108 patients were included, with a mean ± SD age of 73 ± 11 years. Of these, 41 (38%) experienced at least 1 postoperative complication and 22 (20.4%) died within 12 months after surgery. When the authors controlled for potential known confounders, the CCI score was significantly associated with postoperative adverse events (OR 1.20, 95% CI 1.00-1.42, p = 0.045) and trended toward significance for mortality (OR 1.19, 95% CI 0.97-1.45, p = 0.098). In contrast, mFI score and ISS were not significantly predictive of either outcome. CONCLUSIONS Complications in spine trauma patients with ASD may be driven by comorbidity burden rather than operative or injury-related factors. The CCI may be a valuable tool for the evaluation of this unique population.

Abstract
BACKGROUND Most posterior spinal fusion (PSF) patients do not require admission to an intensive care unit (ICU), and those who do may represent an underinvestigated, high-risk subpopulation. OBJECTIVE To identify the microbial profile of and risk factors for surgical site infection (SSI) in PSF patients admitted to the ICU postoperatively. METHODS We examined 3965 consecutive PSF patients treated at our institution between 2000 and 2015 and collected demographic, clinical, and procedural data. Comorbid disease burden was quantified using the Charlson Comorbidity Index (CCI). We performed multivariable logistic regression to identify risk factors for SSI, readmission, and reoperation. RESULTS Anemia, more levels fused, cervical surgery, and cerebrospinal fluid leak were positively associated with ICU admission, and minimally invasive surgery was negatively associated. The median time to infection was equivalent for ICU patients and non-ICU patients, and microbial culture results were similar between groups. Higher CCI and undergoing a staged procedure were associated with readmission, reoperation, and SSI. When stratified by CCI into quintiles, SSI rates show a strong linear correlation with CCI ( P = .0171, R = 0.941), with a 3-fold higher odds of SSI in the highest risk group than the lowest (odds ratio = 3.15 [1.19, 8.07], P = .032). CONCLUSION Procedural characteristics drive the decision to admit to the ICU postoperatively. Patients admitted to the ICU have higher rates of SSI but no difference in the timing of or microorganisms that lead to those infections. Comorbid disease burden drives SSI in this population, with a 3-fold greater odds of SSI for high-risk patients than low-risk patients.

Comparison of frailty metrics and the Charlson Comorbidity Index for predicting adverse outcomes in patients undergoing surgery for spine metastases. J Neurosurg Spine 2022; 36:849-857. [PMID: 34826820 DOI: 10.3171/2021.8.spine21559] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Accepted: 08/24/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Frailty-the state defined by decreased physiological reserve and increased vulnerability to physiological stress-is exceedingly common in oncology patients. Given the palliative nature of spine metastasis surgery, it is imperative that patients be healthy enough to tolerate the physical insult of surgery. In the present study, the authors compared the association of two frailty metrics and the widely used Charlson Comorbidity Index (CCI) with postoperative morbidity in spine metastasis patients. METHODS A retrospective cohort of patients who underwent operations for spinal metastases at a comprehensive cancer center were identified. Data on patient demographic characteristics, disease state, medical comorbidities, operative details, and postoperative outcomes were collected. Frailty was measured with the modified 5-item frailty index (mFI-5) and metastatic spinal tumor frailty index (MSTFI). Outcomes of interest were length of stay (LOS) greater than the 75th percentile of the cohort, nonroutine discharge, and the occurrence of ≥ 1 postoperative complication. RESULTS In total, 322 patients were included (mean age 59.5 ± 12 years; 56.9% of patients were male). The mean ± SD LOS was 11.2 ± 9.9 days, 44.5% of patients had nonroutine discharge, and 24.0% experienced ≥ 1 postoperative complication. On multivariable analysis, increased frailty on mFI-5 and MSTFI was independently predictive of all three outcomes: prolonged LOS (OR 1.67 per point, 95% CI 1.06-2.63, p = 0.03; and OR 1.63 per point, 95% CI 1.29-2.05, p < 0.01, respectively), nonroutine discharge (OR 2.65 per point, 95% CI 1.74-4.04, p < 0.01; and OR 1.69 per point, 95% CI 1.36-2.11, p < 0.01), and ≥ 1 complication (OR 1.95 per point, 95% CI 1.23-3.09, p = 0.01; and OR 1.41 per point, 95% CI 1.12-1.77, p < 0.01). CCI was found to be independently predictive of only the occurrence of ≥ 1 postoperative complication (OR 1.45 per point, 95% CI 1.22-1.72, p < 0.01). CONCLUSIONS Frailty measured with either mFI-5 or MSTFI scores was a more robust independent predictor of adverse postoperative outcomes than the more widely used CCI. Both mFI-5 and MSTFI were significantly associated with prolonged LOS, higher complication rates, and nonroutine discharge. Further investigation in a prospective multicenter cohort is merited.

Abstract
OBJECTIVES The Charlson Comorbidity Index score (CCI) records the presence of comorbidities with various weights for a total score to estimate mortality within 1 year of hospital admission. Our study sought to assess the association of CCI with mortality rates of patients undergoing surgical intervention. STUDY DESIGN Retrospective study. METHODS Retrospective study of patients with surgical spinal trauma at a large academic level I trauma tertiary center from 2015 to 2018. Information collected included age, sex, American Society of Anesthesiologists physical status, body mass index, Charlson comorbidities, injury severity score, the presence of spinal cord injury, and mortality. Mortality was measured at 30 days, 90 days, and 1 year. Descriptive and bivariate analyses were completed. The results were significant at P < 0.05. RESULTS The highest proportion of 1-year mortality was in the patients with cervical (11.3%) and thoracolumbar injuries (7.4%) (P = 0.002). Patients with low CCI had low 1-year mortality (1.7%). Patients with high CCI had high 1-year mortality (13.8%) (P < 0.001). A significant association existed between CCI and mortality at 30 days, 90 days, and 1 year (P < 0.001). Mortality was higher in patients with spinal cord injury (14/108; 13%) than in those without (11/232; 5%) (P = 0.021). No association existed between ISS and mortality (P = 0.26). DISCUSSION The CCI was associated with a higher proportion of deaths at 30 days, 90 days, and 1 year. This association may help predict this unfortunate complication and guide the surgical team in formulating treatment plans and counseling patients and families regarding mortality associated with these injuries and the risks of surgical intervention.

Abstract
BACKGROUND The complication rate for palliative surgery in spinal metastasis is relatively high, and major complications can impair the patient's activities of daily living. However, surgical indications are determined based primarily on the prognosis of the cancer, with the risk of complications not truly considered. We aimed to identify the risk predictors for perioperative complications in palliative surgery for spinal metastasis. METHODS A multicentered, retrospective review of 195 consecutive patients with spinal metastasis who underwent palliative surgeries with posterior procedures from 2001 to 2016 was performed. We evaluated the type and incidence of perioperative complications within 14 days after surgery. Patients were categorized into either the complication group (C) or no-complication group (NC). Univariate and multivariate analyses were used to identify potential predictors for perioperative complications. RESULTS Thirty patients (15%) experienced one or more complications within 14 days of surgery. The most frequent complications were surgical site infection (4%) and motor weakness (3%). A history of diabetes mellitus (C; 37%, NC; 9%: p < 0.01) and surgical time over 300 min (C; 27%, NC; 12%: p < 0.05) were significantly associated with complications according to univariate analysis. Increased blood loss and non-ambulatory status were determined to be potential risk factors. Of these factors, multivariate logistic regression revealed that a history of diabetes mellitus (OR: 6.6, p < 0.001) and blood loss over 1 L (OR: 2.7, p < 0.05) were the independent risk factors for perioperative complications. There was no difference in glycated hemoglobin A1c between the diabetes patients with and without perioperative complications. CONCLUSIONS Diabetes mellitus should be used for the risk stratification of surgical candidates regardless of the treatment status, and strict prevention of bleeding is needed in palliative surgeries with posterior procedures to mitigate the risk of perioperative complications.

Abstract
Type-II odontoid fractures are common and highly morbid injuries, particularly among elderly patients. However, few risk stratification resources exist to predict outcomes and guide management decision making. Frailty indices have been increasingly utilized for these purposes in elective surgery, but have not been assessed for trauma. A single-center prospective trauma registry identified patients aged ≥ 80 years with type-II odontoid fractures. Frailty was the independent variable, using three independent indices: modified-5-item frailty (mFI-5), modified Charlson comorbidity (mCCI), and Davies. 97 patients had complete frailty data and sufficient follow up information, with median mIF-5 of 2 (range 0-4; 34 frail, mFI-5 > 2), median mCCI score of 6 (range 4-14), and median Davies score of 2 (range 0-7). For all indices, increasing score was associated with mortality, mIF-5 (HR = 1.76, 95%CI = 1.06-2.88), mCCI (HR = 1.10, 95%CI = 1.01-1.20), and Davies scores (HR = 1.21, 95%CI = 1.08-1.37). Median post-injury survival among patients with mIF-5 of ≤ 2 was 10-fold longer than patients with mIF-5 of > 2 (70 vs. 710 days, p = 0.0026). After adjusting for initial treatment strategy, frailty status remained an independent predictor of patient mortality; mIF-5 (HR = 1.72, 95%CI = 1.02-2.80), mCCI (HR = 1.10, 95%CI = 1.01-1.20), and Davies scores (HR = 1.21, 95%CI = 1.08-1.37). Among octogenarian patients with type-II odontoid fractures, frailty was associated with increased mortality, independent of treatment strategy.

Abstract
Background Experimental studies have reported that angiotensin receptor blockers (ARBs) increase the risk of surgical complications. However, clinical data on their effect on surgical outcomes are limited. The aim of this study was to investigate the impact of perioperative use of ARBs on the outcomes of breast reconstruction using population-based claim data. Methods Data of patients who underwent direct-to-implant or abdomen-based autologous breast reconstruction after total mastectomy from April 2015 to December 2018 were obtained from the Health Insurance Review and Assessment Service database. The patients were categorized as ARB, non-ARB, control, and non-hypertension groups. The effects of ARBs on surgical complications, length of hospital stay, and complication-related medical costs were evaluated. Results Of the 9,036 patients who met the inclusion criteria, 5,192 underwent direct-to-implant reconstruction, and 3,844 underwent abdomen-based autologous reconstruction. The length of hospital stay was the longest and the surgical complication rate and complication-related medical cost were the highest in the ARB group after both reconstruction methods. Compared with non-treatment with antihypertensive drugs, ARB use was found to be an independent risk factor for surgical complications in direct-to-implant reconstruction [odds ratio (OR), 1.96; 95% confidence interval (CI), 1.09-3.50; P=0.0237] and complication-related medical cost (OR, 1.93; 95% CI, 1.10-3.40; P=0.0221) in abdomen-based autologous reconstruction. Conclusions Perioperative ARB use was associated with adverse postoperative breast reconstruction outcomes. These findings might have a significant impact on perioperative antihypertensive management; nevertheless, further studies are warranted to confirm the study findings.

Abstract
STUDY DESIGN Retrospective. OBJECTIVE Evaluate the association between comorbidity burden and reaching minimum clinically important difference (MCID) following lumbar decompression (LD). SUMMARY OF BACKGROUND DATA There is limited research on the influence of preoperative comorbidity burden on patient-reported outcome improvement following LD. METHODS A prospectively maintained surgical registry was retrospectively reviewed for eligible spine surgeries between 2015 and 2019. Inclusion criteria were primary, single, or multilevel LD. Patients were excluded for missing preoperative patient-reported outcome surveys. Stratification was based on Charlson Comorbidity Index (CCI) score: 0 points (no comorbidities), 1-2 points (low CCI), ≥3 points (high CCI). Demographics and perioperative characteristics were evaluated for differences. Linear regression assessed postoperative improvement for visual analogue scale (VAS) back, VAS leg, Oswestry disability index (ODI), Short Form-12 Physical Composite Score (SF-12 PCS), and Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF) scores through 1 year. Achievement rate of MCID was compared between groups and evaluated for significant predictors. RESULTS Three hundred fourteen patients were included (123 no comorbidities, 100 low CCI, 91 high CCI). Higher CCI patients were older, more likely to smoke, and have comorbid diseases (all P<0.001). Perioperative differences included increased operative time, levels decompressed, length of stay, and discharge day in the CCI≥3 group. No differences in the rate of achieving MCID for VAS back, VAS leg, and ODI. CCI≥3 subgroup had a lower rate of reaching MCID at 6 months for SF-12 PCS, at 6 weeks for PROMIS-PF, and the overall rate for both SF-12 PCS and PROMIS-PF (all P<0.05). Multilevel procedures was a predictor for MCID achievement for ODI. CONCLUSIONS Patients with increased comorbidities undergoing LD had an equivalent MCID achievement rate for pain and disability metrics through 1 year. High CCI patients did, however, have a lower rate of achieving MCID for their physical function surveys which suggests that comorbidity burden influences improvement in physical function following LD.

Abstract
OBJECTIVE To investigate the complication rates and long-term implant failure rates in a monocentric study of a consecutive cohort of patients with thoracolumbar spinal metastases after posterior instrumentation with a fenestrated carbon fiber-reinforced poly-ether-ether-ketone (CFRP) pedicle screw system. METHODS We retrospectively reviewed demographics, Karnofsky Performance Status Scale scores, complications, and implant failure rates. RESULTS Between June 2016 and November 2019, 51 consecutive patients underwent cement-augmented CFRP pedicle screw instrumentation at our institution. Mean age was 68 years (standard deviation 10.5), the median preoperative Karnofsky Performance Status Scale of 80 increased to 90 postoperatively (P = 0.471). Most common primary entities were breast (25.5%), lung (15.7%), and prostate (13.7%) cancers. Of 428 placed screws, 293 (68.5%) were augmented with polymethylmethacrylate, a mean 6 per patient (standard deviation ±2). Screws were inserted via a minimally invasive system technique in 54.9% of cases. In total, 11.8% of patients had immediate postoperative sequelae related to the cement. Pulmonary cement embolisms were noted in 3 patients, 2 had paravertebral extravasation, and 1 had an embolism into a segmental artery. Of these 6, 2 patients with pulmonary embolisms reported related symptoms. Follow-up was available for 80.4%. After a mean 9.8 months, screw loosening was noted in 11.8% of cases on computed tomography, although it was asymptomatic in all but 1 patient. Screw pull-out did not occur. Neither cement-related (P = 0.353) nor general complication rates (P = 0.507) differed significantly between open and minimally invasive system techniques. CONCLUSIONS Percutaneous cement-augmented CFRP pedicle screw instrumentation facilitates artifact-reduced postoperative imaging, while maintaining a risk profile and implant failure rates comparable to conventional metallic instrumentation.

Abstract
BACKGROUND There is a scarcity of research on the Charlson Comorbidity Index (CCI) and its influence on minimum clinically important difference (MCID) achievement after minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF). The objective of this study is to detail the association between the CCI and attaining MCID after MIS TLIF. METHODS A prospective surgical registry was retrospectively reviewed for spine surgeries between May 2015 and February 2019. Inclusion criteria were primary or revision, 1- or 2-level MIS TLIF procedures. Patients were stratified based on CCI score: 0 points (no comorbidities), 1-2 points (mild CCI), ≥3 points (moderate CCI). Preoperative, intraoperative, and postoperative variables were assessed by subgroup using appropriate statistical analysis. Subgroups were analyzed with linear regression or χ2 tests for continuous or categorical variables, respectively. Subgroup scores, improvement, and MCID achievement were assessed at postoperative timepoints (eg, 6 weeks, 12 weeks, 6 months, and 1 year) for back and leg pain, Oswestry Disability Index (ODI), SF-12 Physical Composite Score (PCS), and Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS PF). RESULTS A total of 171 patients were included (n = 51 [no comorbidities], n = 73 [mild CCI], and n = 47 [moderate CCI]). Higher CCI patients were older and more likely to be smokers, diabetic, arthritic, hypertensive, or have a malignancy history (P < 0.003). Preoperatively, ODI and PROMIS PF were the only patient-reported outcomes with a significant association by CCI group (P = 0.015 and 0.014). Back pain was the only measure that had a significant association with the CCI subgroup at 1 year for score (P = 0.002) or MCID (P = 0.028). CONCLUSIONS By 1 year, regardless of the number of comorbidities, a similar proportion of patients undergoing MIS TLIF were able to achieve MCID for visual analog scale leg, SF-12 PCS, and PROMIS PF. Patients with higher comorbidities are not likely to experience a significant difference in symptom improvement. Regardless of CCI score, MIS TLIF can have a significant benefit for patients.

Impact of Multidisciplinary Intraoperative Teams on Thirty-Day Complications After Sacral Tumor Resection. World Neurosurg 2021; 152:e558-e566. [PMID: 34144170 DOI: 10.1016/j.wneu.2021.06.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 06/01/2021] [Accepted: 06/02/2021] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To evaluate the impact of multidisciplinary intraoperative teams on surgical complications in patients undergoing sacral tumor resection. METHODS We reviewed all patients with primary or metastatic sacral tumors managed at a single comprehensive cancer center over a 7-year period. Perioperative complication rates were compared between those treated by an unassisted spinal oncologist and those treated with the assistance of at least 1 other surgical specialty. Statistical analysis involved univariable and stepwise multivariable logistic regression models to identify predictors of multidisciplinary management and 30-day complications. RESULTS A total of 107 patients underwent 132 operations for sacral tumors; 92 operations involved multidisciplinary teams, including 54% of metastatic tumor operations and 74% of primary tumor operations. Patients receiving multidisciplinary management had higher body mass indexes (29.8 vs. 26.3 kg/m2; P = 0.008), larger tumors (258 vs. 55 cm³; P < 0.001), and higher American Society of Anesthesiologists scores (3 vs. 2; P = 0.049). Only larger tumor volume (odds ratio [OR], 1.007 per cm³; P < 0.001) and undergoing treatment for a malignant primary versus a metastatic tumor (OR, 23.4; P < 0.001) or benign primary tumor (OR, 29.3; P < 0.001) were predictive of multidisciplinary management. Although operations involving multidisciplinary teams were longer (467 vs. 231 minutes; P < 0.001) and had higher blood loss (1698 vs. 774 mL; P = 0.004), 30-day complication rates were similar (37 vs. 27%; P = 0.39). On multivariable analysis, only larger tumor volume (OR, 1.004 per cm³; P = 0.005) and longer surgical duration (OR, 1.002 per minute; P = 0.03) independently predicted higher 30-day complications. CONCLUSIONS Although patients managed with multidisciplinary teams had larger tumors and worse baseline health, 30-day complications were similar. This finding suggests that the use of multidisciplinary teams may help to mitigate surgical morbidity in those with high baseline risk.

Charlson Comorbidity Index score predicts adverse post-operative outcomes after far lateral lumbar discectomy. Clin Neurol Neurosurg 2021; 206:106697. [PMID: 34030078 DOI: 10.1016/j.clineuro.2021.106697] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 05/13/2021] [Accepted: 05/16/2021] [Indexed: 11/28/2022]
Abstract
INTRODUCTION The Charlson Comorbidity Index (CCI) score has been shown to predict 10-year all-cause mortality and post-neurosurgical complications but has never been examined in a far lateral disc herniation (FLDH) population. This study aims to correlate CCI score with adverse outcomes following FLDH repair. PATIENTS AND METHODS All patients (n = 144) undergoing discectomy for FLDH at a single, multihospital academic medical system (2013-2020) were retrospectively analyzed. CCI scores were determined for all patients. Univariate logistic regression was used to determine the ability of CCI score to predict adverse outcomes. RESULTS Mean age of the population was 61.72 ± 11.55 years, 69 (47.9%) were female, and 126 (87.5%) were non-Hispanic white. Patients underwent either open (n = 92) or endoscopic (n = 52) FLDH repair. Average CCI score among the patient population was 2.87 ± 2.42. Each additional point in CCI score was significantly associated with higher rates of readmission (p = 0.022, p = 0.014) in the 30-day and 30-90-day post-surgery window, respectively, and emergency department visits (p = 0.011) within 30-days. CCI score also predicted risk of reoperation of any kind (p = 0.013) within 30 days of the index operation. In addition, CCI score was predictive of risk of reoperation of any kind (p = 0.008, p < 0.001; respectively) and repeat neurosurgical intervention (p = 0.027, p = 0.027) within 30-days and 90-days of the index admission (either during the same admission or after discharge). CONCLUSIONS This study suggests that CCI score is a useful metric to predict of numerous adverse postoperative outcomes following discectomy for FLDH.

J Orthop Surg Res 2021; 16:235. [PMID: 33785033 PMCID: PMC8008557 DOI: 10.1186/s13018-021-02377-7] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Accepted: 03/21/2021] [Indexed: 11/10/2022] Open
Abstract
Background In several previous studies, Charlson comorbidity index (CCI) score was associated with postoperative complications, mortality, and re-admission. There are few reports about the influence of CCI score on postoperative clinical outcome. The purpose of this study was to investigate the influence of comorbidities as calculated with CCI on postoperative clinical outcomes after PLIF. Methods Three hundred sixty-six patients who underwent an elective primary single-level PLIF were included. Postoperative clinical outcome was evaluated with the Japanese Orthopaedic Association lumbar score (JOA score). The correlation coefficient between the CCI score and postoperative improvement in JOA score was investigated. Patients were divided into three groups according to their CCI score (0, 1, and 2+). JOA improvement rate, length of stay (LOS), and direct cost were compared between each group. Postoperative complications were also investigated. Results There was a weak negative relationship between CCI score and JOA improvement rate (r = − 0.20). LOS and direct cost had almost no correlation with CCI score. The JOA improvement rate of group 0 and group 1 was significantly higher than group 2+. LOS and direct cost were also significantly different between group 0 and group 2+. There were 14 postoperative complications. Adverse postoperative complications were equivalently distributed in each group, and not associated with the number of comorbidities. Conclusions A higher CCI score leads to a poor postoperative outcome. The recovery rate of patients with two or more comorbidities was significantly higher than in patients without comorbidities. However, the CCI score did not influence LOS and increased direct costs. The surgeon must take into consideration the patient’s comorbidities when planning a surgical intervention in order to achieve a good clinical outcome.

Abstract
BACKGROUND Surgery for spinal metastasis is rapidly increasing in frequency with procedures ranging from laminectomy to spondylectomy combined with stabilization. This study investigated the effect of various surgical procedures for spinal metastasis of non-small cell lung cancer (NSCLC). METHODS A single-center consecutive series of patients who underwent surgery for spinal metastasis of NSCLC were retrospectively reviewed. Patients' characteristics, radiographic parameters, operative data, clinical outcomes, and complications were analyzed. Surgical outcomes were assessed according to pain and performance status before and after surgery. Overall survival (OS) rate was estimated using the Kaplan-Meier method. Multivariate analysis was performed to detect factors independently associated with OS using a Cox proportional hazards model. RESULTS Twenty-one patients were treated with laminectomy, 24 with corpectomy, 13 with spondylectomy (piecemeal or total en bloc fashion), and all procedures were combined with stabilization. Back pain and performance status improved significantly after surgical treatment among the three groups. Revision surgery due to tumor progression at the index level or spinal metastasis at another level were four patients (19.0%) in the laminectomy group, six patients (25.0%) in the corpectomy group, and one patient (7.7%) in the spondylectomy group. A Charlson comorbidity index and the number of spinal metastasis negatively affected OS (hazard ratio [HR], 19.613 and 2.244). Postoperative chemotherapy, time to metastasis, spondylectomy, and corpectomy had favorable associations with OS (HR, 0.455, 0.487, 0.619, and 0.715, respectively). CONCLUSION Postoperative chemotherapy was the most critical factor in OS of patients with metastatic NSCLC to the spine. An extensive surgical procedure (corpectomy/spondylectomy) with stabilization also could be beneficial for limited patients with spinal metastasis of NSCLC.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To evaluate a scoring system to predict morbidity for patients undergoing metastatic spinal tumor surgery (MSTS). SUMMARY OF BACKGROUND DATA Multiple scoring systems exist to predict survival for patients with spinal metastasis. The potential benefits and risks of surgery need to be evaluated for patients with disseminated cancer and limited life expectancy. Few scoring systems exist to predict perioperative morbidity after MSTS. METHODS We reviewed records of patients who underwent MSTS at our institution between 2013 and 2019. All perioperative complications occurring within 30 days were recorded. A clinical scoring system consisting of five variables (age ≥ 70 yr, hypoalbuminemia, poor preoperative functional status [Karnofsky ≤ 40], Frankel Grade A-C, and multilevel disease ≥2 continuous vertebral bodies) was evaluated as a predictive tool for morbidity; every parameter was assigned a value of 0 if absent or 1 if present (total possible score = 5). The effect of the scoring system on morbidity was evaluated using stepwise multiple logistic regression. Model accuracy was calculated by receiver operating characteristic analysis. RESULTS One hundred and five patients were identified, with a male prevalence of 58.1% and average age at surgery of 61 years. The overall 30-day complication rate was 36.2%. The perioperative morbidity was 4.6%, 30.0%, 53.9%, and 64.7% for patients with scores of 0, 1, 2, and ≥3 points, respectively (P < 0.001). On multiple logistic regression analysis controlling for covariates not present in the model, the scoring system was significantly associated with 30-day morbidity (OR 3.11; 95% CI, 1.72-5.59; P < 0.001). The model's accuracy was estimated at 0.75. CONCLUSION Our proposed model was found to accurately predict perioperative morbidity after MSTS. The Spine Oncology Morbidity Assessment (SOMA) score may prove useful for risk stratification and possibly decision-making, though further validation is needed.Level of Evidence: 4.

Abstract
In order to better educate patients, predictive models have been implemented to stratify surgical risk, thereby instituting greater uniformity across surgical practices and prioritizing the safety and outcomes of patients. The purpose of this study is to conduct a systematic review summarizing the major predictive models used to evaluate patients as candidates for spinal surgery. A search was conducted for articles related to predictive modeling in spinal surgeries using PubMed, MEDLINE, and Scopus databases. Papers with area under the receiver operating curve (AUROC) scores reported were included in the analysis. Models not relevant to spinal procedures were excluded. Comparison between models was only attainable for those that reported AUROCs for individual procedures. Based on a combination of AUROC scores and demonstrated applicability to spinal procedures, the models by Scheer et al. (0.89), Ratliff et al. (0.70), the Seattle Spine Score (0.712), Risk Assessment Tool (0.67-0.7), and the Spine Sage calculator (0.81-0.85) were determined to be ideal for predictive modeling in spinal surgeries and were subsequently broken down into their individual inputs and outputs to determine what elements a theoretical model should assimilate. Alongside the model by Scheer et al., the Spine Sage calculator, Seattle Spine Score, Risk Assessment Tool, and a model by Ratliff et al. showed the most promise for patients undergoing spinal procedures. Using the first model as a springboard, new spinal predictive models can be optimized through use of larger prospective databases, with longer follow-up times, and greater inclusion of reliable high impact variables.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES The purpose was to analyze the effect of care bundle protocol on SSI in our institution. Postoperative surgical site infections (SSI) pose significant health burden. In spite of the use of prophylactic antibiotics, surgical advances and postoperative care, wound infection continues to affect patient outcomes after spine surgery. METHODS Retrospective analysis of 9607 consecutive patients who underwent spine procedures from 2014 to 2018 was performed. Preventive care bundle was implemented from January 2017 consisting of (a) preoperative bundle-glycemic control, chlorhexidine gluconate (CHG) bath, (b) intra-operative bundle-time specified antibiotic prophylaxis, CHG+ alcohol-based skin preparation (c) postoperative bundle-five moments of hand hygiene, early mobilization and bundle auditing. Patients operated from January 2017 were included in the post-implementation cohort and prior to that the pre-implementation cohort was formed. Data were drawn from weekly and yearly spine audits from the hospital infection committee software. Infection data were collected based on CDC criteria, further sub classification was done based on procedure, spinal disorders and spine level. Variables were analyzed and level of significance was set as < 0.05. RESULTS A total of 7333 patients met the criteria. The overall SSI rate decreased from 3.42% (131/3829) in pre-implementation cohort to 1.22% (43/3504, p = 0.0001) in post-implementation cohort (RR = 2.73, OR = 2.79). Statistically significant reduction was seen in all the groups (a) superficial and deep, (b) early and late and (c) instrumented and uninstrumented groups but was more pronounced in early (p = 0.0001), superficial (p = 0.0001) and instrumented groups (p = 0.0001). On subgroup analysis based on spine level and spinal disorders, significant reduction was seen in lumbar (p = 0.0001) and degenerative group (p = 0.0001). CONCLUSIONS Our study revealed significant reduction of SSI secondary to strict bundle adherence and monitored compliance compared to patients who did not receive these interventions.

Abstract
BACKGROUND Diabetes mellitus (DM) is associated with poor postoperative outcomes and increased morbidity after surgeries. Some previous studies have addressed the close association between DM and those leading to reoperations, whereas others have rejected this theory. This study aimed to evaluate the long-term effect of DM on lumbar spinal surgery using data from a nationwide sample cohort. METHODS A population-based cohort comprised one million people, which is a 2.1% representative sample of the Korean population. The present study included adult patients with lumbar degenerative diseases (e.g., lumbar spinal stenosis and spondylolisthesis), who underwent their first lumbar surgery in 2006. The cumulative incidence function for reoperation was calculated and multivariate analysis was performed to define correlation between reoperation and independent factors. RESULTS A total of 2020 patients were enrolled and followed up for 10 years. Nondiabetic patients, patients with DM without complication (DwoC), and patients with DM with complication (DwC) accounted for 79.5%, 9.36%, and 11.14% of all patients, respectively. Reoperation incidence stratified by DM was 12.7% for nondiabetic patients, 22.2% for patients with DwoC, and 20.0% for patients with DwC in 10 years of follow-up. During the same period, death, a competing event of reoperation, occurred in 7.8% of nondiabetic patients, in 13.2% of patients with DwoC, and in 20.9% of patients with DwC. CONCLUSIONS DM increased 1.65 times the overall cumulative incidences of reoperation after lumbar spinal surgeries for 10 years of follow-up. The reoperation incidence for DwC may be lower than that for DwoC because of a high incidence of death as a competing event of reoperation.

Methods
A retrospective analysis of consecutive patients operated for metastatic spinal disease. The possible prognostic preoperative characteristics were gender, age, comorbidities, tumor growth rate, and leukocyte and lymphocyte count in the peripheral blood. The postoperative outcomes were 30-day mortality, 90-day mortality and presence of complications. A predictive model was developed based on factors independently associated with these three outcomes. The final model was then tested for the tendency to predict adverse events, discrimination capacity and calibration.
Results
A total of 205 patients were surgically treated between 2002 and 2015. The rates of the 30-day mortality, 90-day mortality and presence of complications were of 17%, 42% and 31% respectively. The factors independently associated with these three outcomes, which constituted the predictive model, were presence of comorbidities, no slow-growing primary tumor, and lymphocyte count below 1,000 cells/µL. Exposure to none, one, two or three factors was the criterion for the definition of the following categories of the predictive model: low, moderate, high and extreme risk respectively. Comparing the risk categories, there was a progressive increase in the occurrence of outcomes, following a linear trend. The discrimination capacity was of 72%, 73% and 70% for 30-day mortality, 90-day mortality and complications respectively. No lack of calibration occurred.
Conclusion
The predictive model estimates morbidity and mortality after spinal metastasis surgery and hierarchizes risks as low, moderate, high and extreme.

Abstract
STUDY DESIGN A retrospective review of prospectively collected data. OBJECTIVE The purpose of this study is to compare and validate several preoperative scores for predicting outcomes following spine tumor resection. SUMMARY OF BACKGROUND DATA Preoperative risk assessment for patients undergoing spinal tumor resection remains challenging. At present, few risk assessment tools have been validated in this high-risk population. METHODS The 2008 to 2014 National Surgical Quality Improvement database was used to identify all patients undergoing surgical resection of spinal tumors, stratified as extradural, intradural extramedullary, and intramedullary based on CPT codes. American Society of Anesthesiologists (ASA) score, modified Charlson Comorbidity Index (CCI), and modified Frailty Index (mFI) were computed. A binary logistic regression model was used to explore the relationship between these variables and postoperative outcomes, including mortality, major and minor adverse events, and hospital length of stay (LOS). Other significant variables such as demographics, operative time, and tumor location were controlled for in each model. RESULTS Two thousand one hundred seventy patients met the inclusion criteria. Higher CCI scores were independent predictors of mortality (OR = 1.24, 95% CI: 1.14-1.36, P < 0.001), major adverse events (OR = 1.07, 95% CI: 1.01-1.31, P = 0.018), minor adverse events (OR = 1.15, 95% CI: 1.10-1.20, P < 0.001), and prolonged LOS (OR = 1.14, 95% CI: 1.09-1.19, P < 0.001). Patients' mFI scores were significantly associated with mortality and LOS, but not major or minor adverse events. ASA scores were not associated with any outcome metric when controlling for other variables. CONCLUSION The CCI demonstrated superior predictive capacity compared with mFI and ASA scores and may be valuable as a preoperative risk assessment tool for patients undergoing surgical resection of spinal tumors. The validation of assessment scores is important for preoperative risk stratification and improving outcomes in this high-risk group. LEVEL OF EVIDENCE 3.

Spine J 2019; 19:144-156. [PMID: 29864546 DOI: 10.1016/j.spinee.2018.05.037] [Citation(s) in RCA: 53] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Revised: 04/29/2018] [Accepted: 05/24/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Postoperative morbidity may offset the potential benefits of surgical treatment for spine metastatic disease; hence, risk factors for postoperative complications and reoperations should be taken into considerations during surgical decision-making. In addition, it remains unknown whether complications and reoperations shorten these patients' survival. PURPOSE We aimed to describe and identify factors associated with having a complication within 30 days of index surgery as well as factors associated with having a subsequent reoperation. Furthermore, we assessed the effect of 30-day complications and reoperations on the patients' postoperative survival, as well as described neurologic changes after surgery. STUDY DESIGN Retrospective cohort study. PATIENT SAMPLE We included 647 patients 18 years and older who had surgery for metastatic disease in the spine between January 2002 and January 2014 in one of two affiliated tertiary care centers. OUTCOME MEASURES Our primary outcomes were complications within 30 days after surgery and reoperations until final follow-up or death. METHODS We used multivariate logistic regression to identify risk factors for 30-day complications and reoperations. We used the Cox regression analysis to assess the effect of postoperative complications and reoperations on survival. RESULTS From 647 included patients, 205 (32%) had a complication within 30 days. The following variables were independently associated with 30-day complications: lower albumin levels (odds ratio [OR]: 0.69, 95% confidence interval [CI]=0.49-0.96, p=.021), additional comorbidities (OR=1.42, 95% CI=1.00-2.01, p=.048), pathologic fracture (OR=1.41, 95% CI=0.97-2.05, p=.031), three or more spine levels operated upon (OR=1.64, 95% CI=1.02-2.64, p=.027), and combined surgical approach (OR=2.44, 95% CI=1.06-5.60, p=.036). One hundred and fifteen patients (18%) had at least one reoperation after the initial surgery; prior radiotherapy (OR=1.56, 95% CI=1.07-2.29, p=.021) to the spinal tumor was independently associated with reoperation. 30-day complications were associated with worse survival (hazard ratio [HR]=1.40, 95% CI=1.17-1.68, p<.001), and reoperation was not significantly associated with worse survival (HR=0.80, 95% CI=0.09-1.00, p=.054). Neurologic status worsened in 42 (6.7%), remained stable in 445 (71%), and improved in 140 (22%) patients after surgery. CONCLUSIONS Three or more spine levels operated upon and prior radiotherapy should prompt consideration of a preoperative plastic surgery consultation regarding soft tissue coverage. Furthermore, if time allows, aggressive nutritional supplementation should be considered for patient with low preoperative serum albumin levels. Surgeons should be aware of the increase in complications in patients presenting with pathologic fracture, undergoing a combined approach, and with any additional preoperative comorbidities. Importantly, 30-day complications were associated with worsened survival.

Abstract
Objective Patients with extradural spine tumors are at an increased risk for intraoperative cerebrospinal fluid (CSF) leaks and postoperative wound dehiscence due to radiotherapy and other comorbidities related to systemic cancer treatment. In this case series, we discuss our experience with the management of intraoperative durotomies and wound closure strategies for this complex surgical patient population. Methods We reviewed our recent single-center experience with spine surgery for primarily extradural tumors, with attention to intraoperative durotomy occurrence and postoperative wound-related complications.
Results A total of 105 patients underwent tumor resection and spinal reconstruction with instrumented fusion for a multitude of pathologies. Twelve of the 105 patients (11.4%) reviewed had intraoperative durotomies. Of these, 3 underwent reoperation for a delayed complication, including 1 epidural hematoma, 1 retained drain, and 1 wound infection. Of the 93 uncomplicated index operations, there were a total of 9 reoperations: 2 for epidural hematoma, 3 for wound infection, 2 for wound dehiscence, and 2 for recurrent primary disease. One patient was readmitted for a delayed spinal fluid leak. The average length of stay for patients with and without intraoperative durotomy was 7.3 and 5.9 days, respectively, with a nonsignificant trend for an increased length of stay in the durotomy cases (p=0.098).
Conclusion Surgery for extradural tumor resections can be complicated by CSF leaks due to the proximity of the tumor to the dura. When encountered, a variety of strategies may be employed to minimize subsequent morbidity.

Abstract
STUDY DESIGN A retrospective database study. OBJECTIVE The aim of this study was to develop and validate a sliding scale for predicting perioperative complications associated with adult spinal deformity (ASD) surgery. SUMMARY OF BACKGROUND DATA ASD surgery can have high perioperative complication rates, which is associated with increased morbidity and mortality. METHODS Data on consecutive ASD patients undergoing posterior corrective surgery over a 6-year interval were collected from a prospective database. The patients' preoperative general condition, surgical status, and perioperative complications occurring within 30 days of surgery were analyzed and independent predictors were determined using multivariable logistic regression analysis. We made the sliding scale using cut-off values from receiver operating curve analysis and validated the performance of this model. RESULTS Three hundred four patients were included with a mean age of 62.9 years. One hundred eight patients (35.5%) were affected by at least one perioperative complication with a total of 195 perioperative complications, including neurological (12.8%), excessive blood loss (11.2%), delirium (11.2%), and infection (3.6%). Total independent predictors were age [odds ratio (OR): 1.042], operation time (OPT) (OR: 2.015), and estimated blood loss (EBL) (OR: 4.885) with cut-off values of approximately 70 years, 6 hours, and 2000 mL, respectively. Fusion of ≥10 segments (OR: 2.262), three-column osteotomy (OR: 1.860), current use of antihypertensive (OR: 2.595) and anticoagulant (OR: 7.013), and body mass index (OR: 1.160) were risk factors for neurological complications, infection, and deep vein thrombosis/pulmonary thrombosis. Our proposed sliding scale had a sensitivity of 91%, specificity of 58.1%, and the incidence of perioperative complication in the validation dataset was smaller than that without this scale (P ≤ 0.05). CONCLUSION Patients' age, current medication, and degenerative pathology might be independent preoperative as well as operative predictors. An age and comorbidities based sliding scale with classifications of OPT and EBL may be useful for risk prediction in ASD surgery. LEVEL OF EVIDENCE 3.

Abstract
STUDY DESIGN Retrospective review of patients who underwent surgery for spinal metastasis between 2005 and 2011. OBJECTIVE To assess the utility of the surgical Apgar score (SAS) in patients who underwent surgery for spinal metastasis. SUMMARY OF BACKGROUND DATA Surgery for spinal metastasis can be associated with relatively high morbidity and mortality. Consequently, identifying patients at risk for major postoperative complications is important. Several studies have validated SAS for predicting 30-day complication risk. METHODS SASs were calculated and patients stratified into 5 groups: scores 0-2, 3-4, 5-6, 7-8, 9-10 points. Multivariate logistic regression assessed whether SAS was an independent predictor of major complication 30 days after surgery. Multivariate analysis of covariance assessed whether SAS was independently associated with length of stay. RESULTS Ninety-seven patients with a variety of metastatic tumors were analyzed. There was no obvious trend in complication rates, or significant association between SAS and complication rate (P=0.413). Complication rates were 25.0% for SASs 0-2, 33.3% for 3-4, 18.4% for 5-6, 10.0% for 7-8, and 33.3% for 9-10 points. On multivariate analysis, SAS was not independently associated with complications; age above 65 years (odds ratio 4.19; 95% confidence interval, 1.31-52.27; P=0.028) and preoperative Karnofsky Performance Score of 10-40 (odds ratio 9.13; 95% confidence interval, 1.42-58.63; P=0.020) were associated with higher odds of complication. SASs 0-2 were an independent predictor of longer hospital stay (P=0.004). CONCLUSIONS Our findings suggest that SAS is not a significant predictor of major perioperative complications after spinal metastasis surgery; preoperative functional status and age are stronger predictors. The need continues for a preoperative scoring system to reliably predict risk for perioperative complications after spinal metastasis surgery.

Abstract
PURPOSE To assess the safety of surgical intervention for extraspinal tumors in the cervical spine. METHODS 110 consecutive patients were enrolled and followed-up at least 12 months or until death. The complication rates and risk factors were documented and analyzed. RESULTS The quality of life in the surviving patients was significantly improved. The overall local recurrence rate was 17.3%. Twenty percent of patients developed distant metastasis. The perioperative mortality rate (30 days after surgery) was 0.9%. The complication related mortality was 1.8%. The rates of overall complication and major complication were 41.8% and 20.9%, respectively. The independent predictors for overall complications were Karnofsky score <60, multisegmental resection, and operation time >3 h. The independent predictors of major complications were comorbidity, tumor location at C1-C2, and combined approach. CONCLUSIONS Surgery for cervical spine tumor could improve the quality of life, though it might be accompanied with high morbidity and mortality. It is a highly demanding procedure; however, it can be performed to an acceptable degree of safety.

Abstract
The incidence of symptomatic spinal metastasis has increased due to treatment improvements and longer patient survival. More patients with spinal tumors are choosing operative treatment with an associated increased rate of perioperative complications. Operative metastatic disease treatment complication rates have also increased with overall rates ranging from 5.3% to 76.20%. The common surgical-related complications are iatrogenic dural injury and wound complications. The most common postoperative medical complications are delirium, pneumonia, and deep vein thrombosis. Risk factors for perioperative complications after spinal metastatic surgery include older age, multilevel of spinal metastases, preoperative irradiation, low preoperative Karnofsky Performance Score (10-40) and multiple comorbidities. Charlson Comorbidity Index and New England Spinal Metastasis Score were significant predictor of 30-day complications. The reoperation rate is 10.7%, and the reoperation is most commonly performed in the same admission. In addition, the 30-day mortality rate in this patient population is ∼7% (0.9%-13%) and is influenced by the type of cancer, disease burden, and patient comorbidities. We reviewed the prevalence and risk factors of common perioperative complications that occur with surgical treatment of metastatic spine disease, in an effort to guide the spine surgeon in anticipating and potentially avoiding these complications.

Abstract
OBJECTIVES The purpose of this study was to explore the relationship between preoperative Charlson Comorbidity Index (CCI) and postoperative length of stay (LOS) for lower extremity and hip/pelvis orthopaedic trauma patients. DESIGN Retrospective. SETTING Urban level 1 trauma center. PATIENTS/PARTICIPANTS A total of 1561 patients treated for isolated lower extremity and pelvis fractures between 2000 and 2012. INTERVENTIONS Surgical intervention for fractures MAIN OUTCOME MEASUREMENTS:: The main outcome metric was LOS. Negative binomial regression analysis was used to examine the association between CCI and LOS while controlling for significant confounders. RESULTS One thousand five hundred sixty-one patients met the inclusion criteria, 1302 (83.4%) of which had lower extremity injuries and 259 (16.6%) experienced hip/pelvis trauma. A total of 1001 (64.1%) patients presented with a CCI score of 1 and stayed an average of 7.9 days. Patients with a CCI of 3 experienced a mean LOS of 1.2 days longer than patients presenting with a CCI of 1, whereas patients presenting with a CCI score of 5 stayed an average of 4.6 days longer. After controlling for age, race, American Society of Anesthesiologists score, sex, anesthesia type, and anesthesia time, a higher preoperative CCI was found to be associated with longer LOS for patients with lower extremity fractures (Incidence Rate Ratio: 1.04, P = 0.01). No significant association was found between CCI and LOS for patients with hip/pelvic fractures. CONCLUSIONS This study demonstrated the potential utility of the CCI as a predictor of hospital LOS for lower extremity patients; however, the association may be small given the smaller Incidence Rate Ratio value. Further studies are needed to clarify the predictive value of the CCI for different types of orthopaedic injuries. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete.

Abstract
BACKGROUND CONTEXT The New England Spinal Metastasis Score (NESMS) was recently proposed to help predict 1-year survival following surgery for spinal metastases. Its ability to predict short-term outcomes, including 30-day morbidity, mortality, and hospital length of stay, has not been evaluated. PURPOSE Assess the capacity of NESMS to predict 30-day morbidity and mortality, as well as hospital length of stay, following surgery for spinal metastases. STUDY DESIGN Validation study. PATIENT SAMPLE All patients who had undergone spinal surgery with a history of metastatic spinal disease within the National Surgical Quality Improvement Program (NSQIP; 2007-2013). OUTCOME MEASURE Mortality, complications, failure to rescue, and length of stay. METHODS Demographic, oncologic, laboratory, and surgical data were obtained from the NSQIP. All patients were assigned an NESMS score (0-3). The effect of the NESMS score on the outcomes of interest was assessed using multivariable logistic regression and negative binomial regression that controlled for confounders. Final model discrimination and calibration were assessed using the c-statistic and Hosmer-Lemeshow test, respectively. Internal validation was performed using a bootstrapping procedure. RESULTS NSQIP data on 776 patients were included in this analysis. The 30-day mortality rate was 11% (N=87), and 51% of patients (N=395) sustained one or more complications. The final adjusted model demonstrated that the NESMS was a statistically significant predictor of 30-day mortality (p<.001), major systemic complications (p<.001), and failure to rescue (p=.03) following metastatic spinal surgery. Patients with an NESMS score of 3 had an 89% reduction in mortality (95% confidence interval [CI]: 0.04, 0.31), a 74% reduction in major systemic complications (95% CI: 0.11, 0.62), and an 88% reduction in failure to rescue (95% CI: 0.03, 0.47) as compared with those with a score of 0. The final model explained 71% of the variation in 30-day mortality. Findings were unchanged in the bootstrap analysis performed among 77,600 patient replicates. CONCLUSION This study demonstrates the clinical accuracy of the NESMS score for predicting short-term major morbidity and mortality following metastatic spinal surgery. The success of this score in an independent cohort of patients collected from centers across the United States indicates its potential for translation to clinical practice.

Abstract
The increasing range of surgery in elderly patients reflects the changing demography where in the next 10 years one quarter of the population will be 65 years of age or older. There is presently no consensus concerning the optimal predictive markers for postoperative morbidity and mortality after surgery in older patients with an appreciation that physical frailty is more important than chronological age. In this retrospective analysis, we have compared the impact of age and the calculated preoperative Charlson Comorbidity Index (CCI) on early (30-day) and late (one-year) mortality in a group of patients >75 years of age dividing them into an “older old” cohort (75–84 years of age, Group A) and an “oldest old” group (≥85 years of age, Group B). Increased age was associated with a higher death rate after emergency surgery, with late deaths after elective surgery exceeding those after emergency operations. A higher mean CCI was noted in both age groups in early nonsurvivors after both elective and emergency surgery with a more significant effect of the preoperative CCI than chronological age for the prediction of late postoperative death for both groups after elective and emergency operations. Although the CCI was not designed to predict perioperative mortality in surgical cohorts, it correlates with a greater risk than age for perioperative death in the elderly.

Abstract
STUDY DESIGN Retrospective analysis of nationally representative data collected for the National Hospital Discharge Survey. OBJECTIVE To compare the performance of the Charlson and Elixhauser comorbidity-based measures for predicting in-hospital mortality after cervical spine fractures. SUMMARY OF BACKGROUND DATA Mortality occurring as a consequence of cervical spine fractures is very high in the elderly. The Charlson comorbidity measure has been associated with an increased risk of mortality, but its predictive accuracy has yet to be compared with the more recent and increasingly used Elixhauser measure. METHODS Using the National Hospital Discharge Survey for the years 1990 through 2007, we identified all patients aged 65 years or older hospitalized with a diagnosis of cervical spine fracture. The association of each Charlson and Elixhauser comorbidity with mortality was assessed in bivariate analysis using χ tests. Two main multivariable logistic regression models were constructed, with in-hospital mortality as the dependent variable and 1 of the 2 comorbidity-based measures (as well as age, sex, and year of admission) as independent variables. A base model that included only age, sex, and year of admission was also evaluated. The discriminative ability of the models was quantified using the area under the receiver operating characteristic curve (AUC). RESULTS Among an estimated 111,564 patients admitted for cervical spine fractures, 7.6% died in the hospital. Elixhauser comorbidity adjustment provided better prediction of in-hospital case mortality (AUC = 0.852, 95% confidence interval: 0.848-0.856) than the Charlson model (AUC = 0.823, 95% confidence interval: 0.819-0.828) and the base model with no comorbidities (AUC = 0.785, 95% confidence interval: 0.781-0.790). In terms of relative improvement in predictive ability, the Elixhauser model performed 43% better than the Charlson model. CONCLUSION The Elixhauser comorbidity risk adjustment method performed numerically better than the widely used Charlson measure in predicting in-hospital mortality after cervical spine fractures.

Abstract
Object
Most descriptions of spine surgery morbidity and mortality in the literature are retrospective. Emerging prospective analyses of adverse events (AEs) demonstrate significantly higher rates, suggesting underreporting in retrospective and prospective studies that do not include AEs as a targeted outcome. Emergency oncological spine surgeries are generally palliative to reduce pain and improve patients' neurology and health-related quality of life. In individuals with limited life expectancy, AEs can have catastrophic implications; therefore, an accurate AE incidence must be considered in the surgical decision-making process. The purpose of this study was to determine the true incidence of AEs associated with emergency oncological spine surgery.
Methods
The authors carried out a prospective cohort study in a quaternary care referral center that included consecutive patients admitted between January 1, 2009, and December 31, 2012. Inclusion criteria were all patients undergoing emergency surgery for metastatic spine disease. AE data were reported and collected on standardized AE forms (Spine AdVerse Events Severity System, version 2 [SAVES V2] forms) at weekly dedicated morbidity and mortality rounds attended by attending surgeons, residents, fellows, and nursing staff.
Results
A total of 101 patients (50 males, 51 females) met the inclusion criteria and had complete data. Seventysix patients (76.2%) had at least 1 AE, and 11 patients (10.9%) died during their admission. Intraoperative surgical AEs were observed in 32% of patients (9.9% incidental durotomy, 16.8% blood loss > 2 L). Transient neurological deterioration occurred in 6 patients (5.9%). Infectious complications in this patient population were significant (surgical site 6%, other 50.5%). Delirium complicated the postoperative period in 20.8% of cases.
Conclusions
When evaluated in a rigorous prospective manner, metastatic spine surgery is associated with a higher morbidity rate than previously reported. This AE incidence must be considered by the patient, oncologist, and surgeon to determine appropriate management and preventative strategies to reduce AEs in this fragile patient population.

Voskuijl T, Hageman M, Ring D. Higher Charlson Comorbidity Index Scores are associated with readmission after orthopaedic surgery. Clin Orthop Relat Res 2014; 472:1638-44. [PMID: 24276857 PMCID: PMC3971213 DOI: 10.1007/s11999-013-3394-8] [Citation(s) in RCA: 153] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2013] [Accepted: 11/14/2013] [Indexed: 01/31/2023]
Abstract
BACKGROUND The Charlson Comorbidity Index (CCI) originally was developed to predict mortality within 1 year of hospital admission in patients without trauma. As it includes factors associated with medical and surgical complexities, it also may be useful as a predictive tool for hospital readmission after orthopaedic surgery, but to our knowledge, this has not been studied. QUESTIONS/PURPOSES We asked whether an increased score on the CCI was associated with (1) readmission, (2) an increased risk of surgical site infection or other adverse events, (3) transfusion risk, or (4) mortality after orthopaedic surgery. METHODS A total of 30,129 orthopaedic surgeries performed between 2008 and 2011 without any orthopaedic surgery in the preceding 30 days were analyzed. International Classification of Diseases, 9(th) Revision codes were used to identify diagnoses, procedures, surgery-related adverse events, surgical site infection, and comorbidities as listed in the updated and reweighted CCI. A total of 913 patients (3.0%) were readmitted within 30 days after discharge; in 393 (1.4%) patients adverse events occurred; 417 patients (1.4%) had a surgical site infection develop; 211 (0.7%) needed transfusions, and 56 (0.2%) died within 30 days after surgery. Ordinary least squares regression analyses were used to determine whether the CCI was associated with these outcomes. RESULTS The CCI accounted for 10% of the variation in readmissions. Every point increase in CCI score added an additional 0.45% risk in readmission for patients undergoing arthroplasty, 0.63% for patients undergoing trauma surgery, and 0.9% risk for patients undergoing spine surgery (all p < 0.01). The CCI was not associated with surgical site infection or other adverse events, but accounted for 8% of the variation in transfusion rate and 10% of the variation in mortality within 30 days of surgery. CONCLUSIONS The CCI can be used to estimate the risk of readmission after arthroplasty, hand and upper extremity surgery, spine surgery, and trauma surgery. It also can be used to estimate the risk of transfusion after arthroplasty, spine, trauma, and oncologic orthopaedic surgery and the risk of mortality after shoulder, trauma, and oncologic orthopaedic surgery.
