RESUMO
BACKGROUND: Clinical practice in postoperative bracing after posterior single-level lumbar spine fusion (PLF) is inconsistent between providers. This study seeks to assess the effect of bracing on short-term outcomes related to safety, quality of care, and direct costs. METHODS: Retrospective cohort analyses of consecutive patients undergoing single-level PLF with or without bracing at a three-hospital urban academic medical center (2013-2017) were undertaken (n = 906). Patient demographics and comorbidities were analyzed. Test of independence, Mann-Whitney-Wilcoxon test, and logistic regression were used to assess differences in length of stay (LOS), discharge disposition/need for postacute care, quality-adjusted life year (QALY), surgical site infection (SSI), hospital cost, total cost, readmission within 30 days, and emergency room (ER) visits within 30 days. RESULTS: Among the study population, 863 patients were braced and 43 were not braced. No difference was seen between the two groups in short-term outcomes from surgery including LOS (P = 0.836), discharge disposition (P = 0.226), readmission (P = 1.000), ER visits (P = 0.281), SSI (P = 1.000), and QALY gain (P = 0.319). However, the braced group incurred a significantly higher direct hospital cost (median increase of 41.43%, P < 0.001) compared to the unbraced cohort (bracing cost excluded). There was no difference in graft type (P = 0.145) or comorbidities (P = 0.20-1.00) such as obesity (P = 1.000), smoking (P = 1.000), chronic obstructive pulmonary disease (P = 1.000), hypertension (P = 0.805), coronary artery disease (P = 1.000), congestive heart failure (P = 1.000), and total number of comorbidities (P = 0.228). CONCLUSION: Short-term data suggest that removal of bracing from the postoperative regimen for PLF will not result in increased adverse outcomes but will reduce cost.
RESUMO
BACKGROUND: Use of cervical bracing/collar subsequent to anterior cervical spine discectomy and fusion (ACDF) is variable. Outcomes data regarding bracing after ACDF are limited. Here, we study the impact of bracing on short-term outcomes related to safety, quality of care, and direct costs in multilevel ACDF. METHODS: Retrospective cohort analyses of all consecutive patients undergoing multilevel ACDF with or without bracing from 2013 to 2017 was undertaken (n = 616). Patient demographics and comorbidities were analyzed. Tests of independence and logistic regressions were used to assess differences in length of stay (LOS), discharge disposition (home, assisted rehabilitation facility [ARF], or skilled nursing facility [SNF]), quality-adjusted life year (QALY), direct cost, readmission within 30 days, and emergency room (ER) visits within 30 days. RESULTS: Amongst the study population, 553 were braced and 63 were not braced. There was no difference in comorbidities (P > .05) such as obesity, smoking, chronic obstructive pulmonary disease, hypertension, coronary artery disease, congestive heart failure, and problem list number. A significant difference in American Society of Anesthesiologists (ASA) score was found, with more ASA 2 patients in the braced cohort and more ASA 3 patients in the unbraced cohort (P = .007). LOS was extended for the unbraced group (median 156.9 ± 211.4 versus 86.67 ± 130.6 h, P = .003), and ER visits within 30 days were 0.21 times less likely in the braced group (P = .006). There was no difference in readmission (P = .181), QALY gain (P = .968), and direct costs (P = .689). CONCLUSION: Bracing following multilevel cervical fixation does not alter short-term postoperative course or reduce the risk for early adverse outcomes in a significant manner.
RESUMO
BACKGROUND: Overlapping surgery is a long-standing practice that has not been well studied. The aim of this study was to assess whether overlapping surgery is associated with untoward outcomes for orthopaedic patients. METHODS: Coarsened exact matching was used to assess the impact of overlap on outcomes among elective orthopaedic surgical interventions (n = 18,316) over 2 years (2014 and 2015) at 1 health-care system. Overlap was categorized as any overlap, and subcategories of exclusively beginning overlap and exclusively end overlap. Study subjects were matched on the Charlson comorbidity index score, duration of surgery, surgical costs, body mass index, length of stay, payer, and race, among others. Serious unanticipated events were studied. RESULTS: A total of 3,395 patients had any overlap and were matched (a match rate of 90.8% of 3,738). For beginning and end overlap, matched groups were created, with a match rate of 95.2% of 1043 and 94.7% of 863, respectively. Among matched patients, any overlap did not predict an unanticipated return to surgery at 30 days (8.2% for any overlap and 8.3% for no overlap; p = 0.922) or 90 days (14.1% and 14.1%, respectively; p = 1.000). Patients who had surgery with any overlap demonstrated no difference compared with controls with respect to reoperation, readmission, or emergency room (ER) visits at 30 or 90 days (a reoperation rate of 3.1% and 3.2%, respectively [p = 0.884] at 30 days and 4.2% and 3.5% [p = 0.173] at 90 days; a readmission rate of 10.3% and 11.0% [p = 0.352] at 30 days and 5.5% and 5.2% [p = 0.570] at 90 days; and an ER visit rate of 5.2% and 4.6% [p = 0.276] at 30 days and 4.8% and 4.3% [p = 0.304] at 90 days). Patients with surgical overlap showed reduced mortality compared with controls during follow-up (1.8% and 2.6%, respectively; p = 0.029). Patients with beginning and/or end overlap had a similar lack of association with serious unanticipated events; however, patients with end overlap showed an increased unexpected rate of return to the operating room after reoperation at 90 days (13.3% versus 9.7%; p = 0.015). CONCLUSIONS: Nonconcurrent overlapping surgery was not associated with adverse outcomes in a large, matched orthopaedic surgery population across 1 academic health system. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVE: Our objective was to determine the impact of total preincision infusion time on surgical site infections (SSIs) and establish an optimal time threshold for subsequent prospective study. BACKGROUND: SSIs remain a major cause of morbidity. Although regulated, the total time of infusion of preincision antibiotics varies widely. Impact of infusion time on SSI risk is poorly understood. METHODS: All consecutive patients (n = 46,791) undergoing inpatient surgical intervention were retrospectively enrolled (2014-2015) and monitored for 1 year. Primary outcomes: the presence of SSI infection as predicted by reduced preoperative antibiotic infusion time. SECONDARY OUTCOMES: preintervention compliance, the impact of a quality improvement algorithm to optimize infusion time compliance. Multivariate logistic regression of the retrospective cohort demonstrated predictors of infection. Receiver-operating characteristic analysis demonstrated the timing threshold predictive of infection. Cost impact of avoidable infections was analyzed. RESULTS: Only 36.1% of patients received preincision infusion of vancomycin in compliance with national and institutional standards (60-120âmin). Cephalosporin infusion times were 53 times more likely to be compliant [odds ratio (OR) 53.33, P < 0.001]. Vancomycin infusion times that were not compliant with national standards (less than standard 60-120âmin) did not predict infection. However, significantly noncompliant, reduced preincision infusion time, significantly predicted SSI (<24.6âmin infusion, AUC = 0.762). Vancomycin infusion, initiated too close to surgical incision, predicted increased SSI (OR = 4.281, P < 0.001). Implementation of an algorithm to improve infusion time, but not powered to demonstrate infection /reduction, improved vancomycin infusion start time (257% improvement, P < 0.001) and eliminated high-risk infusions (sub-24.6âmin). CONCLUSIONS: Initially, vancomycin infusion rarely met national guidelines; however, minimal compliance breach was not associated with SSI implications. The retrospective data here suggest a critical infusion time for infection reduction (24.6 min before incision). Prospective implementation of an algorithm led to 100% compliance. These data suggest that vancomycin administration timing should be studied prospectively.

BACKGROUND: As the use of bundled care payment models has become widespread in neurosurgery, there is a distinct need for improved preoperative predictive tools to identify patients who will not benefit from prolonged hospitalization, thus facilitating earlier discharge to rehabilitation or nursing facilities. OBJECTIVE: To validate the use of Risk Assessment and Prediction Tool (RAPT) in patients undergoing posterior lumbar fusion for predicting discharge disposition. METHODS: Patients undergoing elective posterior lumbar fusion from June 2016 to February 2017 were prospectively enrolled. RAPT scores and discharge outcomes were recorded for patients aged 50 yr or more (n = 432). Logistic regression analysis was used to assess the ability of RAPT score to predict discharge disposition. Multivariate regression was performed in a backwards stepwise logistic fashion to create a binomial model. RESULTS: Escalating RAPT score predicts disposition to home (P < .0001). Every unit increase in RAPT score increases the chance of home disposition by 55.8% and 38.6% than rehab and skilled nursing facility, respectively. Further, RAPT score was significant in predicting length of stay (P = .0239), total surgical cost (P = .0007), and 30-d readmission (P < .0001). Amongst RAPT score subcomponents, walk, gait, and postoperative care availability were all predictive of disposition location (P < .0001) for both models. In a generalized multiple logistic regression model, the 3 top predictive factors for disposition were the RAPT score, length of stay, and age (P < .0001, P < .0001 and P = .0001, respectively). CONCLUSION: Preoperative RAPT score is a highly predictive tool in lumbar fusion patients for discharge disposition.

BACKGROUND: Limited data exist on the safety of overlapping surgery, a practice that has recently received widespread attention. OBJECTIVE: To examine the association of overlapping neurosurgery with patient outcomes. METHODS: A total of 3038 routinely scheduled, elective neurosurgical procedures were retrospectively reviewed at a single, multihospital academic medical center. Procedures were categorized into any overlap or no overlap and further subcategorized into beginning overlap (first 50% of procedure only), end overlap (last 50% of procedure only), and middle overlap (overlap at the midpoint). RESULTS: A total of 1030 (33.9%) procedures had any overlap, whereas 278 (9.2%) had beginning overlap, 190 (6.3%) had end overlap, and 476 (15.7%) had middle overlap. Compared with no overlap patients, patients with any overlap had lower American Society of Anesthesiologists scores (P = .0018), less prior surgery (P < .0001), and less prior neurosurgery (P < .0001), though they tended to be older (P < .0001) and more likely in-patients (P = .0038). Any-overlap patients had decreased overall mortality (2.8% vs 4.5%; P = .025), 30- to 90-d readmission rate (3.1% vs 5.5%; P = .0034), 30- to 90-d reoperation rate (1.0% vs 2.0%; P = .03), 30- to 90-d emergency room (ER) visit rate (2.1% vs 3.7%; P = .018), and future surgery on index admission (2.8% vs 7.3%; P < .0001). Multiple regression analysis validated noninferior outcomes for overlapping surgery, except for the association of increased future surgery on index admission with middle overlap (odds ratio 3.99; 95% confidence interval [1.91, 8.33]). CONCLUSION: Overlapping neurosurgery is associated with noninferior patient outcomes that may be driven by surgeon selection of healthier patients, regardless of specific overlap timing.

OBJECTIVE: Assess the safety of overlapping surgery before implementation of new recommendations and regulations. BACKGROUND: Overlapping surgery is a longstanding practice that has not been well studied. There remains a need to analyze data across institutions and specialties to draw well-informed conclusions regarding appropriate application of this practice. METHODS: Coarsened exact matching was used to assess the impact of overlap on outcomes amongst all surgical interventions (n = 61,524) over 1 year (2014) at 1 health system. Overlap was categorized as: any, beginning, or end overlap. Study subjects were matched 1:1 on 11 variables. Serious unanticipated events were studied including unplanned return to operating room, readmission, and mortality. RESULTS: In all, 8391 patients (13.6%) had any overlap and underwent coarsened exact matching. For beginning/end overlap, matched groups were created (total matched population N = 4534/3616 patients, respectively). Any overlap did not predict unanticipated return to surgery (9.8% any overlap vs 10.1% no overlap; P = 0.45). Further, any overlap did not predict an increase in reoperation, readmission, or emergency room (ER) visits at 30 or 90 days (30D reoperation 3.6% vs 3.7%; P = 0.83, 90D reoperation 3.8% vs 3.9%; P = 0.84) (30D readmission 9.9% vs 10.2%; P = 0.45, 90D readmissions 6.9% vs 7.0%; P = 0.90) (30D ER 5.4% vs 5.6%; P = 0.60, 90D ER 4.8% vs 4.7%; P = 0.71). In addition, any overlap was not associated with mortality over the surgical follow-up period (90D mortality 1.7% vs 2.1%; P = 0.06). Beginning/end overlap had results similar to any overlap. CONCLUSION: Overlapping, nonconcurrent surgery is not associated with an increase in reoperation, readmission, ER visits, or unanticipated return to surgery.

OBJECTIVE: Although it is known that intersurgeon variability in offering elective surgery can have major consequences for patient morbidity and healthcare spending, data addressing variability within neurosurgery are scarce. The authors performed a prospective peer review study of randomly selected neurosurgery cases in order to assess the extent of consensus regarding the decision to offer elective surgery among attending neurosurgeons across one large academic institution. METHODS: All consecutive patients who had undergone standard inpatient surgical interventions of 1 of 4 types (craniotomy for tumor [CFT], nonacute redo CFT, first-time spine surgery with/without instrumentation, and nonacute redo spine surgery with/without instrumentation) during the period 2015-2017 were retrospectively enrolled (n = 9156 patient surgeries, n = 80 randomly selected individual cases, n = 20 index cases of each type randomly selected for review). The selected cases were scored by attending neurosurgeons using a need for surgery (NFS) score based on clinical data (patient demographics, preoperative notes, radiology reports, and operative notes; n = 616 independent case reviews). Attending neurosurgeon reviewers were blinded as to performing provider and surgical outcome. Aggregate NFS scores across various categories were measured. The authors employed a repeated-measures mixed ANOVA model with autoregressive variance structure to compute omnibus statistical tests across the various surgery types. Interrater reliability (IRR) was measured using Cohen's kappa based on binary NFS scores. RESULTS: Overall, the authors found that most of the neurosurgical procedures studied were rated as "indicated" by blinded attending neurosurgeons (mean NFS = 88.3, all p values < 0.001) with greater agreement among neurosurgeon raters than expected by chance (IRR = 81.78%, p = 0.016). Redo surgery had lower NFS scores and IRR scores than first-time surgery, both for craniotomy and spine surgery (ANOVA, all p values < 0.01). Spine surgeries with fusion had lower NFS scores than spine surgeries without fusion procedures (p < 0.01). CONCLUSIONS: There was general agreement among neurosurgeons in terms of indication for surgery; however, revision surgery of all types and spine surgery with fusion procedures had the lowest amount of decision consensus. These results should guide efforts aimed at reducing unnecessary variability in surgical practice with the goal of effective allocation of healthcare resources to advance the value paradigm in neurosurgery.
RESUMO
BACKGROUND CONTEXT: Use of cervical bracing/collar subsequent to anterior cervical spine discectomy and fusion (ACDF) is variable. Outcomes data regarding bracing after ACDF are limited. PURPOSE: The purpose of the study is to study the impact of bracing on short-term outcomes related to safety, quality of care, and direct costs in single-level ACDF. STUDY DESIGN/SETTING: This retrospective cohort analysis of all consecutive patients (n = 578) undergoing single-level ACDF with or without bracing from 2013 to 2017 was undertaken. METHODS: Patient demographics and comorbidities were analyzed. Tests of independence (Chi-square, Fisher's exact, and Cochran-Mantel-Haenszel test), Mann-Whitney-Wilcoxon tests, and logistic regressions were used to assess differences in length of stay (LOS), discharge disposition (home, assisted rehabilitation facility-assisted rehabilitation facility, or skilled nursing facility), quality-adjusted life year (QALY), surgical site infection (SSI), direct cost, readmission within 30 days, and emergency room (ER) visits within 30 days. RESULTS: Among the study population, 511 were braced and 67 were not braced. There was no difference in graft type (P = 1.00) or comorbidities (P = 0.06-0.73) such as obesity (P = 0.504), smoking (0.103), chronic obstructive pulmonary disease hypertension (P = 0.543), coronary artery disease (P = 0.442), congestive heart failure (P = 0.207), and problem list number (P = 0.661). LOS was extended for the unbraced group (median 34.00 + 112.15 vs. 77.00 + 209.31 h, P < 0.001). There was no difference in readmission (P = 1.000), ER visits (P = 1.000), SSI (P = 1.000), QALY gain (P = 0.437), and direct costs (P = 0.732). CONCLUSIONS: Bracing following single-level cervical fixation does not alter short-term postoperative course or reduce the risk for early adverse outcomes in a significant manner. The absence of bracing is associated with increased LOS, but cost analyses show no difference in direct costs between the two treatment approaches. Further evaluation of long-term outcomes and fusion rates will be necessary before definitive recommendations regarding bracing utility following single-level ACDF.
RESUMO
OBJECTIVE: The LACE + index (Length of stay, Acuity of admission, Charlson Comorbidity Index (CCI) score, and Emergency department visits in the past 6 months) is a tool utilized to predict 30-90 day readmission and other secondary outcomes. We sought to examine the effectiveness of this predictive tool in patients undergoing brain tumor surgery. PATIENTS AND METHODS: Admissions and readmissions for patients undergoing craniotomy for supratentorial neoplasm at a single, multi-hospital, academic medical center, were analyzed. Key data was prospectively collected with the Neurosurgery Quality Improvement Initiative (NQII)-EpiLog tool. This included all supratentorial craniotomy cases for which the patient was alive at 90 days after surgery (n = 238). Simple logistic regression analyses were used to assess the ability of the LACE + index and subsequent single variables to accurately predict the outcome measures of 30-90 day readmission, 30-90 day emergency department (ED) visit, and 30-90 day reoperation. Analysis of the model's or variable's discrimination was determined by the receiver operating characteristic curve as represented by the C-statistic. RESULTS: The sample included admissions for craniotomy for supratentorial neoplasm (n = 238) from 227 patients, of which 50.00% were female (n = 119). The average LACE + index score was 53.48 ± 16.69 (Range 9-83). The LACE + index did not accurately predict 30-90 day readmissions (P = 0.127), 30-90 day ED visits (P = 0.308), nor reoperations (P = 0.644). ROC confirmed that the LACE + index was little better than random chance at predicting these events in this population (C-statistic = 0.51-0.58). However, a single unit increase in LACE + leads to a 0.97 times reduction in the odds of being discharged home with fair predictive accuracy (P < 0.001, CI = 0.96-0.98, C-statistic = 0.69). CONCLUSION: The results of this study show that the LACE + index is ill-equipped to predict 30-90 day readmissions in the brain tumor population and further analysis of significant covariates or other prediction tools should be undertaken.

BACKGROUND: Several studies have explored the effect of overlapping surgery on patient outcomes, but impact of surgical overlap during wound closure has not been studied. OBJECTIVE: To examine the association of overlap during wound closure and suture time overlap (STO) with patient outcomes in a heterogeneous neurosurgical population. METHODS: Over 4 yr (7/2013-7/2017), 1 7689 neurosurgical procedures were retrospectively reviewed at a single, multihospital academic medical center. STO was defined as all surgeries for which an overlapping surgery occurred, exclusively, during wound closure of the index case being studied. We excluded nonelective cases and overlapping surgeries that involved overlap during surgical portions of the case other than wound closure. Tests of independence and Wilcoxon tests were used for statistical analysis. RESULTS: Patients with STO had a shortened length of hospital stay (100.6 vs 135.1 h; P < .0001), reduced deaths in follow-up (1.59% vs 5.45%; P = .0004), and lower 30- to 90-d readmission rates (3.64% vs 7.47%; P = .0026). Patients with STO had no increase in revision surgery. Patients with STO had longer wound closure times (26.5 vs 23.9 min; P < .0001) but shorter total surgical times (nonclosure surgical time 101.8 vs 133.3 min; P < .0001; and total surgical time 128.3 vs 157.1 min; P < .0001). CONCLUSION: Surgical overlap during wound closure (STO) is associated with improved or at least noninferior patient outcomes, as it pertains to readmissions and wound revisions.

BACKGROUND: Bundled care payment models are becoming more prevalent in neurosurgery. Such systems place the cost of postsurgical facilities in the hands of the discharging health system. Opportunity exists to leverage prediction tools for discharge disposition by identifying patients who will not benefit from prolonged hospitalization and facilitating discharge to post-acute care facilities. OBJECTIVE: To validate the use of the Risk Assessment and Predictive Tool (RAPT) along with other clinical variables to predict discharge disposition in a cervical spine surgery population. METHODS: Patients undergoing cervical spine surgery at our institution from June 2016 to February 2017 and over 50 yr old had demographic, surgical, and RAPT variables collected. Multivariable regression analyzed each variable's ability to predict discharge disposition. Backward selection was used to create a binomial model to predict discharge disposition. RESULTS: A total of 263 patients were included in the study. Lower RAPT score, RAPT walk subcomponent, older age, and a posterior approach predicted discharge to a post-acute care facility compared to home. Lower RAPT also predicted an increased risk of readmission. RAPT score combined with age increased the predictive capability of discharge disposition to home vs skilled nursing facility or acute rehabilitation compared to RAPT alone (P < .001). CONCLUSION: RAPT score combined with age is a useful tool in the cervical spine surgery population to predict postdischarge needs. This tool may be used to start early discharge planning in patients who are predicted to require post-acute care facilities. Such strategies may reduce postoperative utilization of inpatient resources.

BACKGROUND: The LACE+ index (Length of stay, Acuity of admission, Charlson Comorbidity Index score, and Emergency department [ED] visits in the past 6 months) is a tool used to predict 30-day readmissions. We sought to examine this predictive tool in patients undergoing brain tumor surgery. METHODS: Admissions and readmissions for patients undergoing craniotomy for supratentorial neoplasm at a single multihospital academic medical center were analyzed. All brain tumor cases for which the patient was alive at 30 days after surgery were included (n = 352). Simple logistic regression analyses were used to assess the ability of the LACE+ index and subsequent single variables to accurately predict the outcome measures of 30-day readmission, reoperation, and ED visit. Analysis of the model's or variable's discrimination was determined by the receiver operating characteristic curve as represented by the C-statistic. RESULTS: The sample included admissions for craniotomy for supratentorial neoplasm (n = 352). Assessment of the LACE+ index demonstrates a 1.02× increased odds of 30-day readmission for every 1-unit increase in LACE+ score (P = 0.031, CI = 1.00-1.03). Despite this, analysis of the receiver operating characteristic curve indicates that LACE+ index has poor specificity in predicting 30-day readmission (C-statistic = 0.58). A 1-unit increase in LACE+ score also predicts a 0.98× reduction in odds of home discharge (P < 0.001, CI = 0.97-0.99, C-statistic = 0.70). But LACE+ index does not predict 30-day reoperation (P = 0.945) or 30-day ED visits (P = 0.218). CONCLUSIONS: The results of this study demonstrate that the LACE+ index is not yet suitable as a prediction model for 30-day readmission in a brain tumor population.

BACKGROUND: Bundled care payments are increasingly being explored for neurosurgical interventions. In this setting, skilled nursing facility (SNF) is less desirable from a cost perspective than discharge to home, underscoring the need for better preoperative prediction of postoperative disposition. OBJECTIVE: To assess the capability of the Risk Assessment and Prediction Tool (RAPT) and other preoperative variables to determine expected disposition prior to surgery in a heterogeneous neurosurgical cohort, through observational study. METHODS: Patients aged 50 yr or more undergoing elective neurosurgery were enrolled from June 2016 to February 2017 (n = 623). Logistic regression was used to identify preoperative characteristics predictive of discharge disposition. Results from multivariate analysis were used to create novel grading scales for the prediction of discharge disposition that were subsequently compared to the RAPT Score using Receiver Operating Characteristic analysis. RESULTS: Higher RAPT Score significantly predicted home disposition (P < .001). Age 65 and greater, dichotomized RAPT walk score, and spinal surgery below L2 were independent predictors of SNF discharge in multivariate analysis. A grading scale utilizing these variables had superior discriminatory power between SNF and home/rehab discharge when compared with RAPT score alone (P = .004). CONCLUSION: Our analysis identified age, lower lumbar/lumbosacral surgery, and RAPT walk score as independent predictors of discharge to SNF, and demonstrated superior predictive power compared with the total RAPT Score when combined in a novel grading scale. These tools may identify patients who may benefit from expedited discharge to subacute care facilities and decrease inpatient hospital resource utilization following surgery.
