RESUMO

PURPOSE: Length of stay (LOS) is a major driver of cost and quality of care. A bundled payment system makes it essential for orthopaedic surgeons to understand factors that increase a patient's LOS. Yet, minimal data regarding predictors of LOS currently exist. Using the ACS-NSQIP database, this is the first study to identify risk factors for increased LOS for orthopaedic trauma patients and create a personalized LOS calculator. METHODS: All orthopaedic trauma surgery between 2006 and 2013 were identified from the ACS-NSQIP database using CPT codes. Patient demographics, pre-operative comorbidities, anatomic location of injury, and post-operative in-hospital complications were collected. To control for individual patient comorbidities, a negative binomial regression model evaluated hospital LOS after surgery. Betas (ß), were determined for each pre-operative patient characteristic. We selected significant predictors of LOS (p < 0.05) using backwards stepwise elimination. RESULTS: 49,778 orthopaedic trauma patients were included in the analysis. Deep incisional surgical site infections and superficial surgical site infections were associated with the greatest percent change in predicted LOS (ß = 1.2760 and 1.2473, respectively; p < 0.0001 for both). A post-operative LOS risk calculator was developed based on the formula: [Formula: see text]. CONCLUSIONS: Utilizing a large prospective cohort of orthopaedic trauma patients, we created the first personalized LOS calculator based on pre-operative comorbidities, post-operative complications and location of surgery. Future work may assess the use of this calculator and attempt to validate its utility as an accurate model. To improve the quality measures of hospitals, orthopaedists must employ such predictive tools to optimize care and better manage resources.

RESUMO

Background: The treatment for multi-level spinal stenosis in the setting of single-level instability is a common operative scenario for surgeons who treat degenerative lumbar spine pathology. However, there is conflicting evidence regarding the inclusion of adjacent "stable" levels in the arthrodesis construct because of the potential for iatrogenic instability placed on those segments with decompressive laminectomy alone. This study aims to determine whether decompression adjacent to arthrodesis in the lumbar spine is a risk factor for adjacent segment disease (AS Disease). Methods: A retrospective analysis identified consecutive patients over a three-year period who underwent single-level posterolateral lumbar fusion (PLF) in the setting of single or multi-level spinal stenosis. Patients were required to have a minimum of two-year follow-up. AS Disease was defined as the development of new radicular symptoms referable to a motion segment adjacent to the lumbar arthrodesis construct. The incidence of AS Disease and reoperation rates were compared between cohorts. Results: 133 patients met the inclusion criteria with an average follow-up of 54 months. Fifty-four patients had a PLF with adjacent segment decompression, and 79 underwent a single-segment decompression and PLF. 24.1% (13/54) of patients who had a PLF with adjacent level decompression developed AS Disease resulting in a 5.5% (3/54) reoperation rate. 15.2% (12/79) of patients who did not receive an adjacent level decompression developed AS Disease resulting in a reoperation rate of 7.5% (6/79). There was neither a significantly higher rate of AS Disease (p = 0.26) nor reoperation (p = 0.74) between the cohorts. Conclusions: Decompression adjacent to single-level PLF was not associated with an increased rate of AS Disease relative to single-level decompression and PLF.

RESUMO

The Arbeitsgemeinschaft fur Osteosynthese fragen Spine Sacral Injury Classification hierarchically separates fractures based on their injury severity with A-type fractures representing less severe injuries and C-type fractures representing the most severe fracture types. C0 fractures represent moderately severe injuries and have historically been referred to as nondisplaced "U-type" fractures. Injury management of these fractures can be controversial. Therefore, the purpose of this narrative review is to first discuss the Arbeitsgemeinschaft fur Osteosynthese fragen Spine Sacral Injury Classification System and describe the different fracture types and classification modifiers, with particular emphasis on C0 fracture types. The narrative review will then focus on the epidemiology and etiology of C0 fractures with subsequent discussion focused on the clinical presentation for patients with these injuries. Next, we will describe the imaging findings associated with these injuries and discuss the injury management of these injuries with particular emphasis on operative management. Finally, we will outline the outcomes and complications that can be expected during the treatment of these injuries.

RESUMO

STUDY DESIGN: Single-center retrospective cohort. PURPOSE: To compare surgical outcomes of patients based on lumbar drain variables relating to output and duration. OVERVIEW OF LITERATURE: The use of drains following lumbar spine surgery, specifically with respect to hospital readmission, postoperative hematoma, postoperative anemia, and surgical site infections, has been controversial. METHODS: Patients aged ≥18 years who underwent lumbar fusion with a postoperative drain between 2017 and 2020 were included and grouped based on hospital readmission status, last 8-hour drain output (<40 mL cutoff), or drain duration (2 days cutoff). Total output of all drains, total output of the primary drain, drain duration in days, drain output per day, last 8-hour output, penultimate 8-hour output, and last 8-hour delta (last 8-hour output subtracted by penultimate 8-hour output) were collected. Continuous and categorical data were compared between groups. Multivariate logistic regression analysis and receiver operating characteristic (ROC) analysis were performed to determine whether drain variables can predict hospital readmission, postoperative blood transfusions, and postoperative anemia. Alpha was 0.05. RESULTS: Our cohort consisted of 1,166 patients with 111 (9.5%) hospital readmissions. Results of regression analysis did not identify any of the drain variables as independent predictors of hospital readmission, postoperative blood transfusion, or postoperative anemia. ROC analysis demonstrated the drain variables to be poor predictors of hospital readmission, with the highest area under curve of 0.524 (drain duration), corresponding to a sensitivity of 61.3% and specificity of 49.9%. CONCLUSIONS: Drain output or duration did not affect readmission rates following lumbar spine surgery.

RESUMO

STUDY DESIGN: Retrospective Cohort Study. OBJECTIVE: To explore the differences in Medicare reimbursement for lumbar fusion performed at an orthopaedic specialty hospital (OSH) and a tertiary referral center and to elucidate drivers of Medicare reimbursement differences. SUMMARY OF BACKGROUND DATA: To provide more cost-efficient care, appropriately selected patients are increasingly being transitioned to OSHs for lumbar fusion procedures. There are no studies directly comparing reimbursement of lumbar fusion between tertiary referral centers (TRC) and OSHs. METHODS: Reimbursement data for a tertiary referral center and an orthopaedic specialty hospital were compiled through the Centers for Medicare and Medicaid Services. Any patient with lumbar fusions between January 2014 and December 2018 were identified. OSH patients were matched to TRC patients by demographic and surgical variables. Outcomes analyzed were reimbursement data, procedure data, 90-day complications and readmissions, operating room times, and length of stay (LOS). RESULTS: A total of 114 patients were included in the final cohort. The tertiary referral center had higher post-trigger ($13,554 vs. $8,541, P<0.001) and total episode ($49,973 vs. $43,512, P<0.010) reimbursements. Lumbar fusion performed at an OSH was predictive of shorter OR time (ß=0.77, P<0.001), shorter procedure time (ß=0.71, P<0.001), and shorter LOS (ß=0.53, P<0.001). There were no significant differences in complications (9.21% vs. 15.8%, P=0.353) or readmission rates (3.95% vs. 7.89%, P=0.374) between the 2 hospitals; however, our study is underpowered for complications and readmissions. CONCLUSION: Lumbar fusion performed at an OSH, compared with a tertiary referral center, is associated with significant Medicare cost savings, shorter perioperative times, decreased LOS, and decreased utilization of post-acute resources. LEVEL OF EVIDENCE: 3.

RESUMO

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The aim was to investigate the clinical relevance of preoperative caudal adjacent segment degeneration (ASD) in patients undergoing isolated L4-5 fusion to determine a threshold of degeneration at which a primary L4-S1 fusion would be warranted. SUMMARY OF BACKGROUND DATA: Increased motion and biomechanical forces across the adjacent caudal segment in isolated L4-L5 fusion leads to concerns regarding the increased incidence of revision surgery because of the development of ASD. METHODS: Patients who underwent isolated L4-L5 fusion between 2014 and 2019 were reviewed. Pfirrmann grading and the disc heights of the caudal level relative to the rostral level were used to quantify preoperative adjacent degenerative disc disease. To assess the influence of preoperative caudal degenerative disc disease, preoperative disc height ratios (DHRs) were compared for patients who reported minimal, moderate, and severe Oswestry disability index (ODI) sores on postoperative assessment. For each patient-reported outcome measure (PROM), adjacent DDD was compared for those who did and did not meet MCID. An area under curve analysis was used to identify a threshold of degeneration impacting outcomes from the preoperative DHR. RESULTS: A total of 123 patients were studied with an average follow-up of 2.11 years. All patients demonstrated a significant improvement in all PROMs after surgery. When categorizing patients based on the severity of postoperative ODI scores, there were no preoperative differences in the L5-S1 Pfirrmann grading or DHRs. There was a significant association between greater preoperative anterior DHR and an increased number patients who met MCID for visual analog scale back. There were no radiographic differences in preoperative L5-S1 Pfirrmann grade or DHR for ODI, visual analog scale leg, MCS-12, or PCS-12. area under curve analysis was not able to identify a preoperative DHR threshold that reflected worse MCID for any PROM. CONCLUSION: No preoperative radiographic indicators of caudal ASD were predictive of worse clinical outcomes after isolated L4-5 fusion. LEVEL OF EVIDENCE: Level III.

RESUMO

Although the Affordable Care Act (ACA) has been shown to broadly affect access to care, there is little data examining the change in insurance status with regard to nonelective spinal trauma, infection, and tumor patients. The purpose of this study is to evaluate the changes in insurance status before and after implementation of the ACA in patients who present to the emergency room of a single, level 1 trauma and regional spinal cord injury center. Patient demographic and hospital course information were derived from consult notes and electronic medical record review. Spinal consults between January 1, 2013, and December 31, 2015, were initially included. Consults between January 1 and December 31, 2014, were subsequently removed to obtain two separate cohorts reflecting one calendar year prior to ("pre-ACA") and following ("post-ACA") the effective date of implementation of the ACA on January 1, 2014. Compared with the pre-ACA cohort, the post-ACA cohort had a significant increase in insurance coverage (95.0% versus 83.9%, P < 0.001). Post-ACA consults had a significantly shorter length of stay compared with pre-ACA consults (7.94 versus 9.19, P < 0.001). A significantly greater percentage of the post-ACA cohort appeared for clinical follow-up subsequent to their initial consultation compared to the pre-ACA cohort (49.5% versus 35.3%, P < 0.001). Spinal consultation after the implementation of the ACA was found to be a significant positive predictor of Medicaid coverage (odds ratio = 1.96 [1.05, 3.82], P = 0.04) and a significant negative predictor of uninsured status (odds ratio = 0.28 [0.16, 0.47], P < 0.001). Increase in overall insurance coverage, increase in patient follow-up after initial consultation, and decrease in hospital length of stay were all noted after the implementation of the ACA for spinal consultation patients presenting to the emergency department.

RESUMO

STUDY DESIGN: This was a retrospective cohort study. OBJECTIVE: The objective of this study was to determine the effect of a statewide, government-mandated prescription drug monitoring program (PDMP) on patient-initiated phone calls after lumbar and cervical spinal surgery. SUMMARY OF BACKGROUND DATA: Prior studies have examined the most common reasons for a postoperative phone calls, most of which pertain to pain or prescription medications. However, no studies have investigated the effects of mandatory opioid prescription reporting on these calls. METHODS: Patients who underwent lumbar decompression, lumbar fusion, or posterior cervical fusion were retrospectively identified. Patients were sorted into 1 of 2 cohorts based on their procedure date's relation to the initiation of the state's PDMP: "pre-PDMP" and "post-PDMP." All clinical and demographic data were obtained from electronic health records. Telephone communications from or on behalf of patients were retrospectively reviewed. Multivariable logistic regression was performed to determine independent factors associated with a postoperative phone call. RESULTS: Five hundred and twenty-five patients (2689 phone calls) were included in the study. Average number of phone calls per patient increased significantly after PDMP implementation among lumbar (3.27 vs. 5.18, P<0.001), cervical (5.08 vs. 11.67, P<0.001), and all (3.59 vs. 6.30, P<0.001) procedures. Age [odds ratio (OR): 1.05 (1.01, 1.09), P=0.02], cervical procedure [OR: 4.65 (1.93, 11.21), P=0.001], and a post-PDMP date of surgery [OR: 6.35 (3.55, 11.35), P<0.001] were independently associated with an increased likelihood of a postoperative phone call. A higher percentage of calls were in reference to postoperative care (4.6% vs. 2.4%, P=0.01) and wound care (4.3% vs. 1.4%, P<0.001) in the post-PDMP cohort compared with the pre-PDMP cohort. CONCLUSIONS: Patient-initiated telephone calls increased significantly after implementation of a mandatory statewide PDMP. Increasing age, operation involving the cervical spine, and surgery occurring after implementation of the state's PDMP were independently associated with an increased likelihood of postoperative phone call to health care providers.

RESUMO

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The aim of this study was to investigate the differences in Medicare reimbursement for one- to three-level lumbar decompression procedures performed at a tertiary referral center versus an orthopedic specialty hospital (OSH). SUMMARY OF BACKGROUND DATA: Lumbar decompression surgery is one of the most commonly performed spinal procedures. Lumbar decompression also comprises the largest proportion of spinal surgery that has transitioned to the outpatient setting. METHODS: Patients who underwent a primary one- to three- level lumbar decompression were retrospectively identified. Reimbursement data for a tertiary referral center and an OSH were compiled through Centers for Medicare and Medicaid Services. Demographic data, surgical characteristics, and time cost data were collected through chart review. Multivariate regression models were used to determine independent factors associated with total episode of care cost, operating room (OR) time, procedure time, and length of stay (LOS), and to determine independent predictors of having the decompression performed at the OSH. RESULTS: Total episode of care, facility, and non-facility payments were significantly greater at the tertiary referral center than the OSH, as were OR time for one- to three-level procedures, procedure time of all pooled levels, and LOS for one- and two-level procedures. Three-level procedure was independently associated with increased OR time, procedure time, and LOS. Age and two-level procedure were also associated with increased LOS. Procedure at the OSH was associated with decreased OR time and LOS. Charlson Comorbidity Index was a negative predictor of decompression being performed in the OSH setting. CONCLUSION: Significant financial savings to health systems can be expected when performing lumbar decompression surgery at a specialty hospital as opposed to a tertiary referral center. Patients who are appropriate candidates for surgery in an OSH can in turn expect faster perioperative times and shorter LOS.Level of Evidence: 3.

RESUMO

STUDY DESIGN: This is a retrospective comparative review. OBJECTIVE: The objective of this study was to identify the influence of body mass index (BMI) on postsurgical complications and patient reported outcomes measures (PROMs) following lumbar decompression surgery. SUMMARY OF BACKGROUND DATA: Current literature does not accurately identify the impact of BMI on postsurgical complications or outcomes. MATERIALS AND METHODS: Records from a single-center, academic hospital were used to identify patients undergoing 1 to 3-level lumbar decompression surgery. Patients under 18 years of age, those undergoing surgery for infection, trauma, tumor, or revision, and those with <1-year follow-up were excluded. Patients were split into groups based on preoperative BMI: class I: BMI <25.0 kg/m; class II: BMI 25.0-29.9 kg/m; class III: BMI 30.0-34.9 kg/m; and class IV: BMI >35.0 kg/m. Absolute PROM scores, the recovery ratio and the percent of patients achieving minimum clinically important difference between groups were compared and a multiple linear regression analysis was performed. RESULTS: A total of 195 patients were included with 34 (17.4%) patients in group I, 80 (41.0%) in group II, 49 (25.1%) in group III, and 32 (16.5%) in group IV. Average age was 60.0 (58.0, 62.0) years and average follow-up was 13.0 (12.6, 13.4) months. All patients improved significantly within each group, except for class III and class IV patients, who did not demonstrate significant improvements in terms of Mental Component Score (MCS-12) scores (P=0.546 and 0.702, respectively). There were no significant differences between BMI groups for baseline or postoperative PROM values, recovery ratio, or the percent of patients reaching minimum clinically important difference. Multiple linear regression analysis revealed that BMI was not a significant predictor for change in outcomes for any measure. The 30-day readmission rate was 6.2% and overall revision rate at final follow-up was 5.1%, with no significant differences between groups. CONCLUSION: This study's results suggest that BMI may not significantly affect complications or patient outcomes at 1-year in those undergoing lumbar decompression surgery. LEVEL OF EVIDENCE: Level III.

RESUMO

BACKGROUND: The purpose of this study was to identify the risk factors that are significantly associated with hospital length of stay (LOS) following geriatric hip fracture and to use these significant variables to develop a LOS calculator. MATERIALS AND METHODS: This was a retrospective study examining 614 patients treated for geriatric hip fracture between January 2000 and December 2009 at an urban, Level 1 trauma center. A negative binomial regression analysis was used to identify perioperative variables associated with hospital LOS. RESULTS: 614 patients met the inclusion criteria, presenting with a mean age of 78 (±10) years. The most common pre-operative comorbidity was hypertension, followed by diabetes and COPD. After controlling for all collected comorbidities as well as demographics and operative variables, hypertension (IRR: 1.10, p = 0.029) and disseminated cancer (IRR: 1.24, p = 0.007) were found to be significantly associated with LOS. In addition, two demographic/presenting variables, admission to the medicine service (IRR: 1.48, p < 0.001) and male sex (IRR: 1.09, p = 0.034), were shown to be independent risk factors for prolonged LOS. These variables were synthesized into a LOS formula, which estimated LOS to within 3 days of the true length of stay for 0.758 of the series (95% confidence interval: 0.661 to 0.855). CONCLUSIONS: This study identified several comorbidity and perioperative variables that were significantly associated with LOS following geriatric hip fracture surgery. The resulting LOS model may have utility in the risk stratification of orthopaedic trauma patients presenting with hip fracture.

RESUMO

STUDY DESIGN: Retrospective analysis. OBJECTIVE: The incidence of intradural extramedullary (IDEM) spinal tumors is increasing. Excisional laminectomy for removal and decompression is the standard of care, but complications associated with patient age are unreported in the literature. Our objective is to identify if age is a risk factor for postoperative complications after excisional laminectomy of IDEM spinal tumors. METHODS: A retrospective analysis was performed on the 2011 to 2014 ACS-NSQIP (American College of Surgeons National Surgical Quality Improvement Program) database for patients undergoing excisional laminectomy of IDEM spinal tumors. Age groups were determined by interquartile analysis. Chi-squared tests, t tests, and multivariate logistic regression models were employed to identify independent risk factors. Institutional review board approval was not needed. RESULTS: A total of 1368 patients met the inclusion criteria for the study. Group 1 (age ≤ 44) contained 372 patients, group 2 (age 45-54) contained 314 patients, group 3 (age 55-66) contained 364 patients, and group 4 (age > 66) contained 318 patients. The univariate analysis showed that mortality and unplanned readmission were highest among patients in group 4 (1.26%, P = .011, and 10.00%, P = .039, respectively). Postoperative wound complications were highest among patients in group 1 (2.15%, P = .009), and postoperative venous thromboembolism and cardiac complications were highest among patients in group 3 (4.4%, P = .007, and 1.10%, P = .032, respectively). Multivariate logistic regression revealed that elderly age was an independent risk factor for postoperative venous thromboembolism (group 3 vs group 1; odds ratio = 6.739, confidence interval = 1.522-29.831, P = .012). CONCLUSIONS: This analysis revealed that increased age is an independent risk factor for postoperative venous thromboembolism in patients undergoing excisional laminectomy for IDEM spinal tumors.

RESUMO

STUDY DESIGN: Retrospective study. OBJECTIVE: To determine the rates of early postoperative mortality and morbidity in adults with hypoalbuminemia undergoing elective posterior lumbar fusion (PLF). METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) was examined from 2005 to 2012. Current Procedural Terminology (CPT) codes were used to query the database for adults (≥18 years) who underwent PLF and/or posterior/transforaminal lumbar interbody fusion (PLIF/TLIF). Patients were divided into those with normal albumin concentration (≥3.5g/dL) and those with hypoalbuminemia (<3.5 g/dL). Both univariate and multivariate analyses were performed. RESULTS: A total of 2410 patients were included, of whom 2251 (93.4%) were normoalbuminemic and 159 (6.6%) were hypoalbuminemic. Patients with preoperative serum albumin levels <3.5 g/dL were older with a higher American Society of Anesthesiologists (ASA) score, and more comorbidities, including anemia, diabetes, dependent functional status, and preoperative history of chronic steroid therapy. Hypoalbuminemic patients had higher rates of any 30-day perioperative complication (P < .001), unplanned readmission (P = .019), and prolonged length of stay (LOS) >5 days (P < .001). However, hypoalbuminemia was not significantly associated with any specific perioperative complication. On multivariate analysis, preoperative hypoalbuminemia was found to be an independent predictor of prolonged LOS (OR 2.4, 95% CI 1.7-3.5; P < .001) and unplanned readmission (OR 2.7, 95% CI 1.1-6.3; P = .023). CONCLUSION: Hypoalbuminemia was found to be an important predictor of patient outcomes in this population. This study suggests that clinicians should consider nutritional screening and optimization as part of the preoperative risk assessment algorithm. LEVEL OF EVIDENCE: III.

RESUMO

STUDY DESIGN: Retrospective study of prospectively collected data. OBJECTIVE: To analyze the incidence and risk factors for readmissions following anterior lumbar interbody fusion. SUMMARY OF BACKGROUND DATA: No study has yet reported readmission rates for a specific lumbar surgical approach. There is evidence to indicate differences in perioperative complication rates between anterior versus posterior lumbar interbody fusion techniques, which may translate into differences in readmission rates. METHODS: The American College of Surgeons National Surgical Quality Improvement Program is a large multicenter clinical registry that prospectively collects preoperative risk factors, intraoperative variables, and 30-day postoperative morbidity and mortality outcomes from about 400 hospitals nationwide. Current Procedural Terminology codes were used to query the database for adults who underwent anterior lumbar interbody fusion. Patients were separated into groups of those with and without 30-day readmissions. Univariate analysis and multivariate logistic regression were used to analyze the effect of different risk factors on 30-day readmissions. RESULTS: Multivariate analysis showed that morbid obesity (odds ratio 15.6, P = 0.002) and alcohol use (odds ratio 16.9, P = 0.004) independently predicted unplanned 30-day readmission. Sex, pulmonary comorbidity, cardiac comorbidity, and steroid use were not found to be significant independent predictors of unplanned 30-day readmission in anterior lumbar interbody fusion. CONCLUSION: Adult patients undergoing anterior lumbar interbody fusion who were morbidly obese and had history of alcohol use are at increased risk for 30-day readmissions. Future studies should look to directly compare readmission rates and risk factors between alternative lumbar interbody surgical approaches with longer follow-up and more clinical and radiological parameters investigated. LEVEL OF EVIDENCE: 3.

RESUMO

OBJECTIVE: Resection of epidural thoracic spine tumors is uniquely challenging owing to the dangers posed by the surrounding anatomy and the unforgiving nature of the thoracic spinal cord. We assessed the preoperative and postoperative risk factors for 30-day morbidity and mortality in patients undergoing resection of these tumors. METHODS: Adults who underwent laminectomy for excision of thoracic spine tumors from 2011 to 2014 were included. The demographic data and medical comorbidities and major morbidities and mortalities within 30 postoperative days were collected and assessed using multivariate binary logistic analysis. RESULTS: The database search yielded 616 patients, of whom 232 (37.7%) were female. Overall, complications within 30 days of surgery occurred in 322 patients (52.3%). Of the 616 patients, 64 (10.4%) died within 30 days of surgery. Smoking history was associated with significantly greater 30-day morbidity (P = 0.019), as was preoperative anemia for females (P = 0.003) and preoperative hypoalbuminemia (P < 0.0001), with the need for preoperative blood transfusion also leading to greater morbidity (P = 0.001). The presence of preoperative dyspnea and congestive heart failure increased the risk of complications (P = 0.001). Preoperative hypoalbuminemia (odds ratio [OR], 3.6; 95% confidence interval [CI], 1.8-7.0), dependent functional status (OR, 3.6; 95% CI, 1.7-7.6), and bleeding disorder (OR, 7.1; 95% CI, 2.5-20.1) were significantly associated with 30-day mortality. Deep vein thrombosis/pulmonary embolism, nonthrombotic pulmonary complications, and blood transfusions were common post- and perioperative complications. CONCLUSIONS: Excision of epidural thoracic spinal tumors carries a high complication rate. The present series has revealed distinct preoperative and postoperative factors that contribute to 30-day morbidity and mortality for tumors in this region, many of which are amenable to careful preoperative management.

RESUMO

BACKGROUND: Epidural tumors in the lumbar spine represent a unique cohort of lesions with individual risks and challenges to resection. Knowledge of modifiable risk factors are important in minimizing postoperative complications. OBJECTIVE: To determine the risk factors for 30-day morbidity and mortality in patients undergoing extradural lumbar tumor resection. METHODS: A retrospective study of prospectively collected data using the American College of Surgeons National Quality Improvement Program database was performed. Adults who underwent laminectomy for excision of lumbar spine tumors between 2011 and 2014 were included in the study. Demographics and medical comorbidities were collected, along with morbidities and mortalities within 30 postoperative days. A multivariate binary logistic analysis of these clinical variables was performed to determine covariates of morbidity and mortality. RESULTS: The database search yielded 300 patients, of whom 118 (39.3%) were female. Overall, complications within 30 days of surgery occurred in 102 (34%) patients. Significant risk factors for morbidity included preoperative anemia (P < 0.0001), the need for preoperative blood transfusion (P = 0.034), preoperative hypoalbuminemia (P = 0.002), American Society of Anesthesiologists score 3 or 4 (P = 0.0002), and operative time >4 hours (P < 0.0001). Thirty-day mortality occurred in 15 (5%) patients and was independently associated with preoperative anemia (odds ratio 3.4, 95% confidence interval 1.8-6.5) and operative time >4 hours (odds ratio 2.6, 95% confidence interval 1.1-6.0). CONCLUSIONS: Excision of epidural lumbar spinal tumors carries a relatively high complication rate. This series reveals distinct risk factors that contribute to 30-day morbidity and mortality, which may be optimized preoperatively to improve surgical safety.

RESUMO

STUDY DESIGN: Retrospective study of prospectively collected data OBJECTIVE.: The aim of this study was to assess the impact of resident surgeon involvement on patient outcomes following posterior cervical fusion (PCF) surgery. SUMMARY OF BACKGROUND DATA: Recently, there has been a significant uptrend in the number of PCF performed in the United States. Prior studies have investigated patient outcomes after cervical arthrodesis. Despite the heightened concern for patient safety and quality improvement, the data on the safety of resident participation in PCF is sparse. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) was examined from 2005 to 2012. Current Procedural Terminology codes were used to query the database for adults (≥18 years) who underwent PCF. Multivariate logistic regression models were employed on data adjusted by propensity scores to determine whether resident involvement was an independent predictor for the outcomes of interest. RESULTS: A total of 448 cases were assessed in NSQIP. Less than half of these cases involved residents (224, 43.1%). Resident involvement was found to be a significant predictor for blood transfusions [odds ratio (OR) = 1.7, confidence interval (CI) = 1.1-2.6, P = 0.010], length of stay of more than 5 days (OR = 1.6, CI = 1.0-2.6, P = 0.040), and operative time more than 4 hours (OR = 3.6, CI = 1.7-7.4, P = 0.0007). Other independent risk factors for prolonged length of stay included age 81 years or older versus 50 years or younger (OR = 4.7, CI = 1.7-12.6, P = 0.016) and diabetes (OR = 2.3, CI = 1.3-4.1, P = 0.006). In addition, multifusion was identified as a significant risk factor for extended operative time (OR = 1.8, CI = 1.1-2.9, P = 0.023). CONCLUSION: The present study used a large, nationwide sample to assess the impact of resident involvement in PCF. Resident participation was not associated with mortality, but had a minimal association with morbidity. LEVEL OF EVIDENCE: 3.

RESUMO

STUDY DESIGN: Retrospective study of prospectively collected data. OBJECTIVE: To perform a multiinstitutional assessment on the incidence and risk factors for unplanned readmissions following elective posterior lumbar fusion (PLF) surgery. SUMMARY OF BACKGROUND DATA: Understanding what may drive rehospitalizations is a necessary step toward higher quality care. Identifying risk factors for unplanned readmission is especially important for elective PLF, which is a common procedure that is known to be associated with significant adverse events. METHODS: Adult patients undergoing PLF were identified using current procedure terminology (CPT) from the American College of Surgeons National Surgical Quality Improvement Program. Both descriptive and comparative statistics were performed for patient characteristics, clinical factors, and postoperative complications. Subsequently, a step-wise multivariate logistic regression was employed. RESULTS: Of the 2301 patients who met inclusion criteria for this study, 117 were unplanned readmissions (5.1%). These occurred at a mean of 15.9 days (range: 3-30 days) after surgery. The risk-adjusted analysis revealed that bleeding disorder (odds ratio, OR = 2.8, confidence intervals, CI = 1.0-7.6, P = 0.043), insulin dependent diabetes (OR = 2.5, CI = 1.4-4.4, P = 0.004), and total length of stay > 5 days (OR = 1.8, CI = 1.2-2.8, P = 0.009) were independent predictors for unplanned readmission. Significant postoperative complications included wound complications (OR = 27.6, CI = 13.9-54.8, P < 0.0001), pulmonary embolism and/or deep vein thrombosis/thrombophlebitis (OR = 11.9, CI = 5.0-28.5, P < 0.0001), sepsis (OR = 8.5, CI = 2.3-32.1, P = 0.002), and urinary tract infections (OR = 2.4, CI = 0.9-6.9, P = 0.094). CONCLUSION: The unplanned readmission rate for patients undergoing PLF was low, but this study's findings of potentially modifiable risk factors suggest that substantial improvement with this quality metric is possible. LEVEL OF EVIDENCE: N/A.

RESUMO

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: Diabetes mellitus is a highly prevalent disease in the United States. Adult spinal deformity (ASD) surgery encompasses a wide variety of spinal disorders and is associated with a morbidity rate between 20% and 80%. Considering utilization of spinal surgery will continue to increase, this study investigates the influence of diabetes mellitus on acute postoperative outcomes following elective ASD surgery. METHODS: The 2010-2014 American College of Surgeon's National Surgical Quality Improvement Program database was queried using Current Procedural Terminology and International Classification of Diseases (9th Revision) diagnosis codes relevant to ASD surgery. Patients were divided into cohorts based on their diabetic status. Bivariate and multivariate logistic regression analyses were employed to identify which 30-day postoperative outcomes patients are at risk for. RESULTS: A total of 5809 patients met the inclusion criteria for the study of which 4553 (84.2%) patients were nondiabetic, 578 (10.7%) patients had non-insulin-dependent diabetes mellitus (NIDDM), and 275 (5.1%) patients had insulin-dependent diabetes mellitus (IDDM). Diabetes status was significantly associated with length of stay ≥5 days (NIDDM: odds ratio [OR] = 1.27, 95% confidence interval [CI] = 1.02-1.58, P = .034; IDDM: OR = 1.55, 95% CI = 1.15-2.09, P = .004), any complication (NIDDM: OR = 1.26, 95% CI = 1.01-1.58, P = .037), urinary tract infection (NIDDM: OR = 1.87, 95% CI = 1.14-3.05, P = .012), and cardiac complications (IDDM: OR = 4.05, 95% CI = 1.72-9.51, P = .001). CONCLUSIONS: Given the prevalence of diabetes, surgeons will invariably encounter these patients for ASD surgery. The present study identifies the increased risk NIDDM and IDDM patients experience following ASD surgery. Quantification of this increased risk may improve the selection of appropriate surgical candidates, patient risk stratification, and patient postoperative safety.
