Preventing Postoperative Urinary Retention (POUR) in Patients Undergoing Elective Lumbar Surgery: A Quality Improvement Project

BACKGROUND AND OBJECTIVES

Postoperative urinary retention (POUR) is associated with significant morbidity. Our institution's POUR rate was elevated among patients undergoing elective lumbar spinal surgery. We sought to demonstrate that our quality improvement (QI) intervention would significantly lower our POUR rate and length of stay (LOS).

METHODS

A resident-led QI intervention was implemented from October 2017 to 2018 on 422 patients in an academically affiliated community teaching hospital. This consisted of standardized intraoperative indwelling catheter utilization, postoperative catheterization protocol, prophylactic tamsulosin, and early ambulation after surgery. Baseline data on 277 patients were collected retrospectively from October 2015 to September 2016. Primary outcomes were POUR and LOS. The focus, analyze, develop, execute, and evaluate (FADE) model was used. Multivariable analyses were used. P value <.05 was considered significant.

RESULTS

We analyzed 699 patients (277 pre-intervention vs 422 post-intervention). The POUR rate (6.9% vs 2.6%, Δ confidence interval [CI] 1.15-8.08, P = .007) and mean LOS (2.94 ± 1.87 days vs 2.56 ± 2.2 days, Δ CI 0.066-0.68, P = .017) were significantly improved following our intervention. Logistic regression demonstrated that the intervention was independently associated with significantly decreased odds for developing POUR (odds ratio [OR] = 0.38, CI 0.17-0.83, P = .015). Diabetes (OR = 2.25, CI 1.03-4.92, P = .04) and longer surgery duration (OR = 1.006, CI 1.002-1.01, P = .002) were independently associated with increased odds of developing POUR.

CONCLUSIONS

After implementing our POUR QI project for patients undergoing elective lumbar spine surgery, the institutional POUR rate significantly decreased by 4.3% (62% reduction) and LOS, by 0.37 days. We demonstrated that a standardized POUR care bundle was independently associated with a significant decrease in the odds of developing POUR.

INTERVERTEBRAL DISC DISEASE IN THREE LARGE FELIDS (PANTHERA SPP.) TREATED SURGICALLY

Intervertebral disc disease (IVDD) in captive large felids is a commonly encountered syndrome that is usually treated medically, with surgical cases only sparsely documented in the literature. This case series describes the diagnosis, surgical treatment, and postoperative care of three cases of IVDD in large felids: an 8-yr-old male Bengal tiger (Panthera tigris tigris) with acute paraplegia, a 10-yr-old male tiger of unknown subspecies (Panthera tigris) with progressive tetraparesis, and a 17-yr-old female African lion (Panthera leo) with mild paraparesis. Two cases were diagnosed via magnetic resonance imaging (MRI) and the third was diagnosed with computed tomography myelography. Disc herniations were confirmed during surgery in all cases and via necropsy in two cases. Surgical procedures included a thoracolumbar dorsal hemilaminectomy in one tiger, a cervical hemilaminectomy in the other tiger, and a continuous lumbar dorsal hemilaminectomy in the lion. One tiger was euthanized approximately 1 wk after surgery and the other tiger was euthanized approximately 1 mon after surgery, following a lack of clinical improvement in both cases. The lion, however, improved markedly over several months after surgery before acutely declining secondary to spinal neoplasia. Analysis of these cases suggests that pursuing MRI and surgery as soon as possible after the onset of clinical signs and marking affected disc sites based on imaging to provide landmarks for the surgeon may improve long-term prognosis. Additionally, strict postoperative confinement in an accessible cage is beneficial to facilitate care and prevent overexertion while allowing early movement.

Enhanced recovery after surgery: a narrative review on patient blood management recommendations

This review aims to analyze and document the presence of patient blood management (PBM) recommendations in enhanced recovery after surgery (ERAS) guidelines. The aim of ERAS programs is to improve outcomes and optimize patient recovery by reducing the stress response to surgery. PBM programs pursue the objective of improving outcomes by boosting and conserving the patient's own blood. From the early development of ERAS, there was little attention paid to the three pillars of perioperative blood management. Preoperative anemia is an important risk factor in perioperative outcomes and should be diagnosed and treated. Bleeding and unnecessary transfusions should be avoided. We analyzed clinical guidelines for scheduled surgery in adults published by the ERAS Society between 2018 and 2022. The guidelines selected were searched for recommendations related to the three pillars of PBM. We selected 15 ERAS guidelines in programmed surgery in adults. Until 2018, none of the ERAS guidelines analyzed included any recommendations related to pillars I and III of PBM. In 2019, recommendations related to the three pillars of PBM were introduced in the ERAS clinical guidelines for colorectal surgery, gynecology/oncology surgery, and lung resection surgery. However, many ERAS guidelines for surgeries with a high risk of bleeding, such as cardiac surgery, contain no clear recommendations on the management of preoperative anemia. This review shows that the ERAS guidelines published to date make very few recommendations related to PBM. The authors emphasize the need to include the most efficient PBM recommendations in ERAS clinical guidelines, given improved outcomes with a good perioperative management of blood transfusion.

A Beginner's Perspective on Biportal Endoscopic Spine Surgery in Single-Level Lumbar Decompression: A Comparative Study with a Microscopic Surgery

Background

The application of biportal endoscopic spinal surgery (BESS) in spine surgery is increasing. However, the clinical results of related studies have been inconsistent. In this study, the perioperative and clinical outcomes of two techniques in single-level lumbar decompression surgery were compared using the perspective of a spine surgeon experienced in microscopic surgery but inexperienced in BESS.

Methods

This is a retrospective study performed with prospectively collected data. From April 2019, 50 consecutive patients who underwent a single-level lumbar decompression surgery with BESS were evaluated. Additionally, the data of 150 consecutive patients who underwent the same microscopic surgery before April 2019 were collected. We performed 1 : 1 ratio propensity score matching for these two groups to adjust for baseline variables. The postoperative patient-reported outcome measures included the Oswestry Disability Index (ODI) and numeric rating scale for the back and leg preoperatively and at 6 months after surgery. The laboratory data (C-reactive protein [CRP, mg/L] and hemoglobin [Hb, g/dL]) were measured preoperatively and 3 times (1, 2, and 3 or 4 days) postoperatively. In these periods, the peak and lowest CRP and Hb concentrations were evaluated. The perioperative outcomes, operation time (from skin incision to dressing), length of hospital stay, drainage (for 24 hours after surgery), and surgery-related complications were also evaluated.

Results

Forty-seven patients (27 men and 20 women) were included in each group. The postoperative 6-month ODI was significantly lower in the BESS group than in the microscope group (6.90 ± 5.98 vs. 11.54 ± 9.70). The peak CRP concentration (16.63 ± 19.41 vs. 42.40 ± 37.73, p < 0.001) and CRP increment (peak CRP minus preoperative CRP, 14.69 ± 19.47 vs. 40.71 ± 37.32, p < 0.001) were significantly higher in the microscope group. Operation time (83.72 ± 35.71 vs. 70.27 ± 23.24, p = 0.047) was significantly longer in the BESS group. Surgery-related complications were found in 6 and 3 cases in the BESS group (3 revisions, 2 dural tears, and 1 conversion to open surgery) and microscope group (2 revisions and 1 hematoma), respectively.

Conclusions

BESS as a new technique resulted in satisfying short-term outcomes. It was a well-tolerated option for surgical treatment of single-level lumbar degenerative disease. The relatively high incidence of recurrence at the index level and incidental dural tears should be considered for surgeons new to BESS; however, these were manageable complications.

Enhanced Recovery After Surgery Protocols and Spinal Deformity

The authors outline a review of preoperative, intraoperative, and postoperative considerations surrounding adult spinal deformity. Preoperative management topics include imaging, hemoglobin A1c levels before spine surgery, osteoporotic management, and prehabilitation. Topics surrounding intraoperative management include the use of antibiotics, liposomal bupivacaine, and Foley catheters. The authors also discuss postoperative questions surrounding analgesia, nausea and vomiting, thromboembolic prophylaxis, and early mobilization. Throughout their discussion, the authors incorporate enhanced recovery after surgery protocols to hopefully lead to future discussions regarding optimizing complex spinal patients.

Correlation between MRI-based spinal muscle parameters and the vertebral bone quality score in lumbar fusion patients

Introduction

The vertebral bone quality (VBQ) score that is based on non-contrast enhanced T1-weighted MRI was recently introduced as a novel measure of bone quality in the lumbar spine and shown to be a significant predictor of healthy versus osteopenic/osteoporotic bone.

Research question

This study aimed to assess possible correlations between the VBQ score and the functional cross-sectional area (FCSA) of psoas and lumbar spine extensor muscles.

Material and methods

Patients who underwent fusion surgery between 2014 and 2017 and had lumbar MRI and CT scans within 6 months prior to surgery were included. The FCSA was assessed at L3-L5 using a pixel intensity threshold method. The VBQ score was calculated by dividing the signal intensity (SI) of the vertebrae L1-L4 through the SI of the cerebrospinal fluid at L3. Volumetric bone mineral density (vBMD) was assessed by quantitative CT.

Results

80 patients (58.8% female, median age 68.8 years) were included. Overall prevalence of osteopenia/osteoporosis was 66.3%, with no significant differences between men and women. The mean (SD) VBQ score was significantly smaller in men, at 2.26 (0.45) versus women at 2.59 (0.39) (p = 0.001). After adjusting for age and BMI, a significant negative correlation was seen between the VBQ score and psoas FCSA at L3 (β = -0.373; p = 0.022), but only in men.

Conclusion

Our results highlight sex differences in the VBQ score that were not demonstrated by vBMD and suggest a potential role of this novel measure to assess not only bone quality, but also spinal muscle quantity.

Novel Interdisciplinary Enhanced Recovery after Surgery Protocol Implementation in Paediatric Orthopaedics

The enhanced recovery after surgery (ERAS) protocol is not routine management in paediatric orthopaedics. Cultural differences or assumptions about the financing of medical care in different countries encourage creative adaptation of general assumptions in local communities. The aim of this study was to compare the quality of the perioperative period before and after the introduction of an interdisciplinary protocol adopted to organisational conditions. A group of 4098 children were included in the "before-after" observational study. The data of 1553 patients (BEFORE group) were analysed in terms of compliance with the enhanced recovery after surgery protocol guidelines and the time and cost of hospitalisation over a 20-month period. A novel interdisciplinary protocol was developed, including an education and training app called BackOnFeet (BOF®), standardised hospital management, and the introduction of methods novel to Poland (intraoperative nerve cryoanalgesia in children). A further 2545 patients (AFTER group) were reassessed over a period of 20 months. It was found that the groups differed in hospitalisation time (p < 0.001), type of procedures, and percentage ratio of costs incurred to revenue generated. The usefulness of the BOF® app as an effective educational tool was demonstrated. The optimisation of perioperative management in paediatric orthopaedics based on novel tools and the interdisciplinary ERAS protocol is possible and brings tangible benefits in psychological, organisational, and financial terms.

The application of enhanced recovery after surgery (ERAS) in chronic rhinosinusitis patients undergoing endoscopic sinus surgery: A systematic review and meta-analysis

OBJECTIVES

Enhanced recovery after surgery (ERAS) has become extensively practiced and has shown encouraging benefits. Within recent years, ERAS has also been increasingly performed in chronic rhinosinusitis (CRS) patients undergoing endoscopic sinus surgery (ESS). However, the actual efficacy of ERAS in CRS patients undergoing ESS is not completely clear, and the related evidence remains weak. This systematic review and meta-analysis aimed to evaluate the effectiveness and safety of ERAS in the perioperative management of CRS patients receiving ESS.

METHODS

We searched randomized controlled trials in PubMed, Web of Science, EMBASE, Cochrane CENTRAL, Ovid, China National Knowledge Infrastructure, Chinese BioMedical Literature Database, Wanfang, and VIP Database up to February 2023, to analyze the effectiveness and safety of ERAS in ESS perioperative management of CRS patients. We appraised the methodological quality in the included RCTs using the Cochrane Collaboration tool and assessed the quality of evidence with the Recommendations Assessment, Development and Evaluation (GRADE) tool. Meta-analysis, subgroup analysis, and sensitivity analysis were carried out with the the software Review Manager 5.3 and Stata 12.0. In addition, potential publication bias was detected by Begg's test, Egger's test, and funnel plot test.

RESULTS

Twenty-eight studies involving 2636 patients were included within this study. In comparison with the standard care (SC) group, the ERAS group had the advantages in the following aspects: length of stay (MD = -2.50, 95%CI: -3.04 to -1.97), pain scores (MD = -1.07, 95%CI: -1.46 to -0.67), anxiety score (SMD = -2.13, 95%CI: -2.83 to -1.44), depression score (SMD = -2.42, 95%CI: -3.13 to -1.71), hospitalization expenses, and quality of life. At the same time, the ERAS group presented a markedly lower incidence of adverse events in comparison to the SC group, such as overall complications (RR = 0.28, 95%CI:0.20 to 0.41), postoperative nausea and vomiting (RR = 0.33, 95%CI:0.21 to 0.50), facial edema (RR = 0.20, 95%CI:0.11 to 0.38), low back pain (RR = 0.28, 95%CI:0.16 to 0.49), urinary retention (RR = 0.12, 95%CI:0.05 to 0.30) and haemorrhage (RR = 0.19, 95%CI:0.07 to 0.55).

CONCLUSIONS

The results showed that the ERAS protocol is effective and safe in CRS patients who undergo ESS. However, Due to the limited overall methodological quality included studies, caution should be exercised in the interpretation of the results. More high-quality, multiple-centre, and large-sample studies are in demand in the future to further validate its clinical efficacy.

Outpatient Spine Surgery in Poland: A Survey on Popularity, Challenges, and Future Perspectives

Objective

This study aimed to investigate the popularity of outpatient spine surgery in Poland, identify factors influencing its adoption, and assess its benefits, challenges, and impact on patient outcomes and healthcare costs. Additionally, the study proposes strategies to improve outpatient spine surgery adoption and ensure its safe implementation in Poland.

Materials and Methods

An electronic survey was distributed to members of the Polish Spine Surgery Society and the Polish Neurosurgery Society. Data were analyzed using Matlab R2020b statistical software, employing descriptive statistics to summarize the responses.

Results

The survey indicated that 67% of respondents provide spinal procedures commercially, with 58% performing them on an outpatient basis, showing the growing role of the private sector in providing spinal surgery services in Poland. Root nerve blocks and joint blocks were the most common outpatient procedures, followed by microdiscectomy, endoscopic discectomy, and L-S spinal fusion. The public NHF was the most common payer for outpatient procedures.

Conclusion

Outpatient spine surgery in Poland is not yet widespread, but improvements can be made to reduce hospital stays and enhance recovery. Changes in reimbursement systems to cover outpatient procedures and addressing physicians' liability concerns, particularly by emphasizing the NO-fault system, are essential. With proper support, outpatient spine surgery could become a valuable addition to Poland's healthcare system.

Enhanced Recovery After Surgery (ERAS) protocols following emergency intra-abdominal surgery: A systematic review and meta-analysis protocol

OBJECTIVE

The aim of this systematic review and meta-analysis is to evaluate whether the implementation of Enhanced Recovery After Surgery (ERAS) protocols for adult patients undergoing emergency intra-abdominal surgery decreases postoperative length of stay, postoperative morbidity, and mortality compared to conventional perioperative care.

METHODS

A systematic review and meta-analysis will be performed and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). It has been registered on the International Prospective Register for Systematic Reviews (PROSPERO; CRD42023391709). A comprehensive, electronic search strategy will be used to identify studies published and indexed in MEDLINE, EMBASE, Web of Science, CENTRAL, and Pubmed databases since their inception. Trial registries and references of included studies and pertinent previous systematic reviews will also be searched. Studies will be included if they are randomized controlled trials or cohort studies evaluating adult patients undergoing emergency intra-abdominal surgery and comparing ERAS or modified ERAS protocols to conventional perioperative care and report one of the following outcomes: postoperative length of stay, overall 30-day morbidity, 30-day mortality, 30-day infectious morbidity, prolonged postoperative ileus, return of bowel function, and 30-day readmissions. A meta-analysis will be performed using a random effects model for all comparative data using Cochrane Review Manager 5.3 (London, United Kingdom).

DISCUSSION

ERAS protocols have become standard of care for patients undergoing elective surgery. Their use in the setting of emergency surgery is far less common. The aim of this systematic review and meta-analysis is to assess whether there are benefits in patient important outcomes with the implementation of ERAS protocols for patients undergoing emergency intra-abdominal surgery. Ultimately, we hope to promote their use and further large randomized controlled trials evaluating emergency surgery ERAS programs.

A Randomized Controlled Trial to Assess the Impact of Enhanced Recovery After Surgery on Patients Undergoing Elective Spine Surgery

OBJECTIVE

To conduct a prospective, randomized controlled trial (RCT) of an enhanced recovery after surgery (ERAS) protocol in an elective spine surgery population.

BACKGROUND

Surgical outcomes such as length of stay (LOS), discharge disposition, and opioid utilization greatly contribute to patient satisfaction and societal healthcare costs. ERAS protocols are multimodal, patient-centered care pathways shown to reduce postoperative opioid use, reduced LOS, and improved ambulation; however, prospective ERAS data are limited in spine surgery.

METHODS

This single-center, institutional review board-approved, prospective RCT-enrolled adult patients undergoing elective spine surgery between March 2019 and October 2020. Primary outcomes were perioperative and 1-month postoperative opioid use. Patients were randomized to ERAS (n=142) or standard-of-care (SOC; n=142) based on power analyses to detect a difference in postoperative opioid use.

RESULTS

Opioid use during hospitalization and the first postoperative month was not significantly different between groups (ERAS 112.2 vs SOC 117.6 morphine milligram equivalent, P =0.76; ERAS 38.7% vs SOC 39.4%, P =1.00, respectively). However, patients randomized to ERAS were less likely to use opioids at 6 months postoperatively (ERAS 11.4% vs SOC 20.6%, P =0.046) and more likely to be discharged to home after surgery (ERAS 91.5% vs SOC 81.0%, P =0.015).

CONCLUSION

Here, we present a novel ERAS prospective RCT in the elective spine surgery population. Although we do not detect a difference in the primary outcome of short-term opioid use, we observe significantly reduced opioid use at 6-month follow-up as well as an increased likelihood of home disposition after surgery in the ERAS group.

The Role of Prolonged Bed Rest in Postoperative Cerebrospinal Fluid Leakage After Surgery of Intradural Pathology-A Retrospective Cohort Study

BACKGROUND

Postoperative cerebrospinal fluid leakage (CSFL) is a feared complication after surgery on intradural pathologies and may cause postoperative complications and subsequently higher treatment costs.

OBJECTIVE

To assess whether prolonged bed rest may lower the risk of CSFL.

METHODS

We performed a retrospective cohort study including patients with intradural pathologies who underwent surgery at our department between 2013 and 2021. Cohorts included patients who completed 3 days of postoperative bed rest and patients who were mobilized earlier. The primary end point was the occurrence of clinically proven CSFL.

RESULTS

Four hundred and thirty-three patients were included (female [51.7%], male [48.3%]) with a mean age of 48 years (SD ±20). Bed rest was ordered in 315 cases (72.7%). In 7 cases (N = 7/433, 1.6%), we identified a postoperative CSFL. Four of them (N = 4/118) did not preserve bed rest, showing no significant difference to the bed rest cohort (N = 3/315; P = .091). In univariate analysis, laminectomy (N = 4/61; odds ratio [OR] 8.632, 95% CI 1.883-39.573), expansion duraplasty (N = 6/70; OR 33.938, 95% CI 4.019-286.615), and recurrent surgery (N = 5/66; OR 14.959, 95% CI 2.838-78.838) were significant risk factors for developing CSFL. In multivariate analysis, expansion duraplasty was confirmed as independent risk factor (OR 33.937, 95% CI 4.018-286.615, P = .001). In addition, patients with CSFL had significant higher risk for meningitis (N = 3/7; 42.8%, P = .001).

CONCLUSION

Prolonged bed rest did not protect patients from developing CSFL after surgery on intradural pathologies. Avoiding laminectomy, large voids, and minimal invasive approaches may play a role in preventing CSFL. Furthermore, special caution is indicated if expansion duraplasty was done.

The severity of preoperative anemia escalates risk of poor short-term outcomes after lumbar spine fusion

OBJECTIVE

To evaluate how preoperative anemia severity affects 90-day outcomes of spinal fusion surgery.

METHODS

A retrospective cohort study was conducted on adult lumbar fusion patients at a tertiary medical center. Patients were classified by World Health Organization anemia severity definitions for comparisons. Multivariate regression models were created to control for confounding variables, for all primary outcomes of transfusion requirements, non-home discharge, readmissions, complications, and length of stay.

RESULTS

A total of 2582 patients were included: 2.7% with moderate-severe anemia, 11.0% with mild anemia, and 86.3% without anemia. Moderate-severe patients had the longest hospital stay (5.03 days vs 4.14 and 3.59 days, p < 0.001) and highest risk of transfusion (52.2% vs 13.0% vs 2.69%, p < 0.001), non-home discharge (39.1% vs 27.8% vs 15.4%, p < 0.001), readmission (7.25% vs 5.99% vs 3.36%, p = 0.023), and complications (13.0% vs 9.51% vs 6.20%, p = 0.012). On multivariable logistic regression, both patients with mild and moderate-severe anemia had an increased risk of transfusion (OR: 37.3, p < 0.001; OR: 5.25, p < 0.001, respectively) and non-home discharge (OR: 2.00, p = 0.021; OR: 1.71, p = 0.001, respectively) compared to patients without anemia. Anemia severity was not independently associated with complications or 90-day readmission. On multivariable linear regression, mild anemia (β: 0.37, p = 0.001) and moderate-severe anemia (β: 1.07, p < 0.001) were independently associated with length of hospital stay.

CONCLUSION

Patients with moderate-severe preoperative anemia are at increased risk for longer length of stay, transfusions, and non-home discharge. Improved optimization of preoperative anemia may significantly reduce healthcare utilization, and surgeons should consider these risks in preoperative planning.

Immune response to foreign materials in spinal fusion surgery

Spinal fusion surgery is a common procedure used to stabilize the spine and treat back pain. The procedure involves the use of foreign materials such as screws, rods, or cages, which can trigger a foreign body reaction, an immune response that involves the activation of immune cells such as macrophages and lymphocytes. The foreign body reaction can impact the success of spinal fusion, as it can interfere with bone growth and fusion. This review article provides an overview of the cellular and molecular events in the foreign body reaction, the impact of the immune response on spinal fusion, and strategies to minimize its impact. By carefully considering the use of foreign materials and optimizing surgical techniques, the impact of the foreign body reaction can be reduced, leading to better outcomes for patients.

Validation of the Calgary Postoperative Pain after Spine Surgery Score for Poor Postoperative Pain Control after Spine Surgery

OBJECTIVE

The Calgary Postoperative Pain after Spine Surgery (CAPPS) score was developed to identify patients at risk of experiencing poorly controlled pain after spine surgery. The goal of this study was to independently validate the CAPPS score on a prospectively collected patient sample.

METHODS

Poor postoperative pain control was defined as a mean numeric rating scale (NRS) for pain >4 at rest in the first 24 hours after surgery. Baseline characteristics in this study (validation cohort) were compared to those of the development cohort used to create the CAPPS score. Predictive performance of the CAPPS score was assessed by the area under the curve (AUC) and percentage misclassification for discrimination. A graphical comparison between predicted probability vs. observed incidence of poorly controlled pain was performed for calibration.

RESULTS

Fifty-two percent of 201 patients experienced poorly controlled pain. The validation cohort exhibited lower depression scores and a higher proportion using daily opioid medications compared to the development cohort. The AUC was 0.74 [95%CI = 0.68-0.81] in the validation cohort compared to 0.73 [95%CI = 0.69-0.76] in the development cohort for the eight-tier CAPPS score. When stratified between the low- vs. extreme-risk and low- vs. high-risk groups, the percentage misclassification was 21.2% and 30.7% in the validation cohort, compared to 29.9% and 38.0% in the development cohort, respectively. The predicted probability closely mirrored the observed incidence of poor pain control across all scores.

CONCLUSIONS

The CAPPS score, based on seven easily obtained and reliable prognostic variables, was validated using a prospectively collected, independent sample of patients.

Personalized Medicine in Orthopaedic Surgery: The Case of Spine Surgery

Personalized medicine has made a tremendous impact on patient care. Although initially, it revolutionized pharmaceutical development and targeted therapies in oncology, it has also made an important impact in orthopaedic surgery. The field of spine surgery highlights the effect of personalized medicine because the improved understanding of spinal pathologies and technological innovations has made personalized medicine a key component of patient care. There is evidence for several of these advancements to support their usage in improving patient care. Proper understanding of normative spinal alignment and surgical planning software has enabled surgeons to predict postoperative alignment accurately. Furthermore, 3D printing technologies have demonstrated the ability to improve pedicle screw placement accuracy compared with free-hand techniques. Patient-specific, precontoured rods have shown improved biomechanical properties, which reduces the risk of postoperative rod fractures. Moreover, approaches such as multidisciplinary evaluations tailored to specific patient needs have demonstrated the ability to decrease complications. Personalized medicine has shown the ability to improve care in all phases of surgical management, and several of these approaches are now readily available to orthopaedic surgeons.

Intraoperative use of balanced crystalloids versus 0.9% saline: a systematic review and meta-analysis of randomised controlled studies

BACKGROUND

The evidence regarding optimal crystalloid use in the perioperative period remains unclear. As the primary aim of this study, we sought to summarise the data from RCTs examining whether use of balanced crystalloids compared with 0.9% saline (saline) leads to differences in patient-important outcomes.

METHODS

We searched Ovid MEDLINE, Embase, the Cochrane library, and Clinicaltrials.gov, from inception until December 15, 2022, and included RCTs that intraoperatively randomised adult participants to receive either balanced fluids or saline. We pooled data using a random-effects model and present risk ratios (RRs) or mean differences (MDs), along with 95% confidence intervals (CIs). We assessed individual study risk of bias using the modified Cochrane tool, and certainty of evidence using GRADE.

RESULTS

Of 5959 citations, we included 38 RCTs (n=3776 patients). Pooled analysis showed that intraoperative use of balanced fluids compared with saline had an uncertain effect on postoperative mortality analysed at the longest point of follow-up (RR 1.51, 95% CI: 0.42-5.36) and postoperative need for renal replacement therapy (RR 0.95, 95% CI: 0.56-1.59), both very low certainty. Furthermore, use of balanced crystalloids probably leads to a higher postoperative serum pH (MD 0.05, 95% CI: 0.04-0.06), moderate certainty.

CONCLUSIONS

Use of balanced crystalloids, compared with saline, in the perioperative setting has an uncertain effect on mortality and need for renal replacement therapy but probably improves postoperative acid-base status. Further research is needed to determine whether balanced crystalloid use affects patient-important outcomes.

Post-lumbar surgery prescription variation and opioid-related outcomes in a large US healthcare system: an observational study

BACKGROUND CONTEXT

Spinal decompression and fusion procedures are one of the most common procedures performed in the United States (US) and remain associated with high postsurgical opioid burden. Despite guidelines emphasizing nonopioid pharmacotherapy strategies for postsurgical pain management, prescribing practices are likely variable and guideline-incongruent.

PURPOSE

The purpose of this study was to characterize patient-, care-, and system-level factors associated with opioid, nonopioid pain medication, and benzodiazepine prescribing variation in the US Military Health System (MHS).

STUDY DESIGN/SETTING

Retrospective study analyzing medical records from the US MHS Data Repository.

PATIENT SAMPLE

Adult patients (N=6,625) undergoing lumbar decompression and spinal fusion procedures from 2016 to 2021 in the MHS enrolled in TRICARE at least a year prior to their procedure and had at least one encounter beyond the 90-day postprocedure period, without recent trauma, malignancy, cauda equina syndrome, and co-occurring procedures.

OUTCOME MEASURES

Patient-, care-, and system-level factors influencing outcomes of discharge morphine equivalent dose (MED), 30-day opioid refill, and persistent opioid use (POU). POU was defined as dispensing of opioid prescriptions monthly for the first 3 months after surgery and then at least once between 90 and 180 days after surgery.

METHODS

(Generalized) linear mixed models evaluated multilevel factors associated with discharge MED, opioid refill, and POU.

RESULTS

The median discharge MED was 375 mg (IQR 225, 580) and days' supply was 7 days (IQR 4, 10); 36% received an opioid refill and 5%, overall, met criteria for POU. Discharge MED was associated with fusion procedures (+151-198 mg), multilevel procedures (+26 mg), policy release (-184 mg), opioid naïvty (-31 mg), race (Black -21 mg, another race and ethnicity -47 mg), benzodiazepine receipt (+100 mg), opioid-only medications (+86 mg), gabapentinoid receipt (-20 mg), and nonopioid pain medications receipt (-60 mg). Longer symptom duration, fusion procedures, beneficiary category, mental healthcare, nicotine dependence, benzodiazepine receipt, and opioid naivety were associated with both opioid refill and POU. Multilevel procedures, elevated comorbidity score, policy period, antidepressant receipt, and gabapentinoid receipt, and presurgical physical therapy were also associated with opioid refill. POU increased with increasing discharge MED.

CONCLUSIONS

Significant variation in discharge prescribing practices require systems-level, evidence-based intervention.

Development of a Modified Bayonet Forceps for Improving Steerability of Paddle Lead Electrodes During Spinal Cord Stimulator Surgery: A Technical Note

BACKGROUND AND OBJECTIVE

Despite recent advancements in spinal cord stimulation (SCS) technology, the surgical instrumentation for placement of SCS paddle leads remains suboptimal. Therefore, we developed a novel instrument to improve the steerability of SCS paddle leads during surgical placement.

METHODS

A review of existing literature was performed to analyze workflow deficiencies in the standard instrumentation of SCS paddle lead placement. After a period of adaptation and iterative feedback with a medical instrument company, a new instrument was developed, tested at benchtop, and successfully incorporated into the surgical routine.

RESULTS

A standard bayonet forceps was modified to include hooked ends and a ribbed surface, providing the surgeon with greater control over the paddle lead. The new instrument also included bilateral metal tubes starting approximately 4 cm proximal from the edge of the forceps. The bilateral metal tubes, through which the SCS paddle lead wires are passed, serve as anchors to keep the wires away from the incision site. In addition, it permitted the paddle lead to assume a bent configuration, reducing its overall size and allowing it to be placed through a smaller incision and laminectomy. The modified bayonet forceps was successfully used intraoperatively for placement of SCS paddle lead electrodes in several surgeries.

CONCLUSION

The proposed modified bayonet forceps increased steerability of the paddle lead, facilitating optimal midline placement. The bent configuration of the device facilitated a more minimally invasive surgical approach. Future studies are needed to validate our single-provider experience and evaluate the impact of this new instrument on operating room efficiency.

Enhanced recovery after microdiscectomy: reductions in opioid use, length of stay and cost

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols are widely used worldwide. Recently, studies of the ERAS program in spinal surgery subspecialties have been reported. The aim of this study was to evaluate the impacts of ERAS in minimally invasive microdiscectomy (MD) surgery.

METHODS

This was a retrospective cohort study of patients undergoing MD at a single center. From March 2018 to March 2021, 286 patients were in the ERAS group. A total of 140 patients from March 2017 to February 2018 were in the conventional group. The outcomes included length of stay (LOS), the postoperative numeric rating scale (NRS), complications, 30-day readmission rate, 30-day reoperation rate and cost. Moreover, perioperative factors were also evaluated.

RESULTS

Compared with the conventional group, the LOS and cost were reduced in the ERAS group. There were no significant differences in the NRS, complication rate, 30-day readmission or reoperation rates between the groups. Furthermore, postoperative drainage volume, and postoperative opioid use were lower in the ERAS group.

CONCLUSIONS

The ERAS protocol for MD surgery reduces LOS, cost and opioid use and accelerates patient recovery.

Enhanced recovery nursing and mental health education on postoperative recovery and mental health of laparoscopic liver resection

BACKGROUND

Patients undergoing laparoscopic resection of liver metastases of colorectal cancer are prone to negative emotions and decrease of digestive function. Early nursing and psychological intervention are necessary.

AIM

To observe the effect of enhanced recovery nursing combined with mental health education on postoperative recovery and mental health of patients undergoing laparoscopic resection of liver metastases of colorectal cancer.

METHODS

One hundred and twenty patients who underwent laparoscopic resection of liver metastases of colorectal cancer at our hospital between March 2021 and March 2023, were selected as participants. The patients admitted from March 1, 2021 to February 28, 2022 were set as the control group, and they were given routine nursing combined with mental health education intervention. While the patients admitted from March 1, 2022 to March 31, 2023 were set as the observation group, they were given accelerated rehabilitation surgical nursing combined with mental health education intervention. The differences in postoperative recovery-related indices, complications and pain degrees, and mental health-related scores were compared between groups. The T lymphocyte subset levels of the two groups were also compared.

RESULTS

The postoperative exhaust, defecation, eating and drainage time of the observation group were shorter than those of the control group. The pain scores of the observation group were lower than those of the control group at 6, 12, 24, 48, and 72 h after surgery. The cumulative complication rate of the observation group was lower than that of the control group (P < 0.05). The CD4+/CD8+ in the observation group was higher than that in the control group 3 d after surgery (P < 0.05). After intervention, the self-rating depression scale, self-rating anxiety scale, avoidance dimension, and yielding dimension in Medical coping style (MCMQ) scores of the two groups were lower than those prior to intervention, and the scores in the observation group were lower than those in the control group (P < 0.05). The face dimension score in the MCMQ score was higher than that before intervention, and that of the observation group was higher than that of the control group (P < 0.05). After intervention, the total scores of the life function index scale (FLIC) and psychological well-being scores of cancer patients in the two groups, and the physical and social well-being scores in the observation group, were higher than those before intervention. The nursing satisfaction of the observation group was higher than that of the control group (P < 0.05). The physical, psychological, and social well-being, and the total FLIC scores of the observation group were higher than those in the control group after surgery (P < 0.05).

CONCLUSION

Enhanced recovery nursing combined with mental health education can promote the recovery of gastrointestinal function, improve the mental health and quality of life of patients after laparoscopic resection of colorectal cancer liver metastases, and reduce the incidence of complications.

Older Adults' Experiences Living With and Having Spine Surgery for Degenerative Spine Disease

BACKGROUND AND OBJECTIVES

Globally, older adults are undergoing spine surgery for degenerative spine disease at exponential rates. However, little is known about their experiences of living with and having surgery for this debilitating condition. This study investigated older adults' understanding and experiences of living with and having surgery for degenerative spine disease.

RESEARCH DESIGN AND METHODS

Qualitative methods, grounded theory, guided the study. Fourteen older adults (≥65 years) were recruited for in-depth interviews at 2 time-points: T1 during hospitalization and T2, 1-3-months postdischarge. A total of 28 interviews were conducted. Consistent with grounded theory, purposive, and theoretical sampling were used. Data analysis included open, axial, and selective coding.

RESULTS

A conceptual model was developed illustrating the process older adults with degenerative spine disease experience, trying to get their life back. Three key categories were identified (1) Losing Me, (2) Fixing Me, and (3) Recovering Me. Losing Me was described as a prolonged process of losing functional independence and the ability to socialize. Fixing Me consisted of preparing for surgery and recovery. Recovering Me involved monitoring progression and reclaiming their personhood. Conditions, including setbacks and delays, slowed their trajectory. Throughout, participants continually adjusted expectations.

DISCUSSION AND IMPLICATIONS

The conceptual model, based on real patient experiences, details how older adults living with and having surgery for degenerative spine disease engage in recovering who they were prior to the onset of symptoms. Our findings provide a framework for understanding a complex, protracted trajectory that involves transitions from health to illness working toward health again.

The Impact of Rocuronium and Sugammadex on Length of Stay in Patients Undergoing Open Spine Surgery: A Propensity Score-Matched Analysis

Enhanced Recovery After Surgery (ERAS), an all-encompassing perioperative care approach, has been demonstrated to enhance surgical results, mitigate postoperative issues, and decrease the length of hospital stay (LOS) in diverse surgical specialties. In this retrospective study, our objective was to examine the influence of muscle relaxant selection on LOS and perioperative results in adult patients undergoing open spine surgery. Specifically, we compared 201 patients who received cisatracurium and neostigmine with 201 patients who received rocuronium and sugammadex, after 1:1 propensity score matching. The utilization of the rocuronium and sugammadex combination in anesthesia for open spinal surgery did not lead to a reduction in the LOS but was associated with a decreased incidence of postoperative chest radiographic abnormalities, including infiltration, consolidation, atelectasis, or pneumonia (p = 0.027). In our secondary analysis, multivariate analysis revealed multiple determinants influencing the prolonged LOS (>7 days) during open spine surgery. Bispectral index-guided anesthesia emerged as a protective factor, while variables such as excessive intraoperative blood loss and fluid administration as well as postoperative chest radiographic abnormalities independently contributed to prolonged LOS.

The effect of in-bed turning and mobilization training given to patients who undergo lumbar disk surgery on postoperative first mobility level: A single-blind, randomized controlled trial

OBJECTIVE

This study was conducted to investigate the effects of mobilization and in-bed turning training given through the role-playing technique to patients to undergo lumbar disk surgery on the patient's pain, strain and dependence level during the first postoperative mobilization (turning, sitting, standing and walking).

METHODS

Patients who would undergo a lumbar disk hernia surgery were recruited from a neurosurgery clinic in Turkey. Patients who met inclusion criteria and agreed to participate (n = 40) in the study were randomly assigned to an intervention group (in-bed turning and mobilization training simulated with the role-playing technique, n = 19) and a control group (usual clinical care, n = 21). The outcome of the study was patient mobility and observer mobility scale scores.

RESULTS

Postoperative scores obtained from the patient mobility and observer mobility scale were lower in the intervention group than the scores of the control group, and the difference between the groups was found statistically significant (p < 0.05). The anxiety levels of the intervention group before (38.00 ± 6.59, p < 0.001) and after mobilization (31.63 ± 4.57, p = 0.032) were significantly lower.

CONCLUSION

The findings indicate training improves patient care outcomes for first postoperative mobility. It is recommended that structured training for in-bed turning and mobilization should be integrated into routine clinical care in the preoperative period for patients to undergo lumbar disk hernia surgery.

PRACTICE IMPLICATIONS

Preoperative training increases the patient's willingness to be mobilized and decreases the anxiety level and perceived pain and strain.

Enhanced recovery after surgery pathway with modified biportal endoscopic transforaminal lumbar interbody fusion using a large cage. Comparative study with minimally invasive microscopic transforaminal lumbar interbody fusion

PURPOSE

Studies about the clinical efficacy of endoscopic lumbar interbody fusion using an enhanced recovery after surgery (ERAS) pathway are insufficient. Thus, the purpose of this study was to investigate clinical usefulness of biportal endoscopic transforaminal lumbar interbody fusion (TLIF) using an ERAS compared with microscopic TLIF.

METHODS

Prospectively collected data were retrospectively analyzed. Patients who received modified biportal endoscopic TLIF with ERAS were grouped into an endoscopic TLIF group. Those who received microscopic TLIF without ERAS were grouped into a microscopic TLIF group. Clinical and radiologic parameters were compared between two groups. Fusion rate was evaluated using sagittal reconstruction images of postoperative computed tomographic (CT) scan.

RESULTS

There were 32 patients in the endoscopic TLIF group with ERAS and 41 patients in the microscopic TLIF group without ERAS. Visual analog scale (VAS) scores for back pain preoperatively at day one and day two were significantly (p < 0.05) higher in the non-ERAS microscopic TLIF group than in the ERAS endoscopic TLIF group. Preoperative Oswestry Disability Index were significantly improved at the last follow-up in both groups. The fusion rate at postoperative one year was 87.5% in the endoscopic TLIF group and 85.4% in the microscopic TLIF group.

CONCLUSION

Biportal endoscopic TLIF with ERAS pathway may have good aspect to accelerate recovery after surgery. There was no inferiority of fusion rate of endoscopic TLIF comparing to microscopic TLIF. Biportal endoscopic TLIF using a large cage with ERAS pathway may be a good alternative treatment for lumbar degenerative disease.

Healthy Eating for Elective Major Orthopedic Surgery: Quality, Quantity, and Timing

Improvements to enhanced recovery pathways in orthopedic surgery are reducing the time that patients spend in the hospital, giving an increasingly vital role to prehabilitation and/or rehabilitation after surgery. Nutritional support is an important tenant of perioperative medicine, with the aim to integrate the patient's diet with food components that are needed in greater amounts to support surgical fitness. Regardless of the time available between the time of contemplation of surgery and the day of admission, a patient who eats healthy is reasonably more suitable for surgery than a patient who does not meet the daily requirements for energy and nutrients. Moreover, a successful education for healthy food choices is one possible way to sustain the exercise therapy, improve recovery, and thus contribute to the patient's long-term health. The expected benefits presuppose that the patient follows a healthy diet, but it is unclear which advice is needed to improve dietary choices. We present the principles of healthy eating for patients undergoing major orthopedic surgery to lay the foundations of rational and valuable perioperative nutritional support programs. We discuss the concepts of nutritional use of food, requirements, portion size, dietary target, food variety, time variables of feeding, and the practical indications on what the last meal to be consumed six hours before the induction of anesthesia may be together with what is meant by clear fluids to be consumed until two hours before. Surgery may act as a vital "touch point" for some patients with the health service and is therefore a valuable opportunity for members of the perioperative team to promote optimal lifestyle choices, such as the notion and importance of healthy eating not just for surgery but also for long-term health benefit.

The influence of enhanced recovery after surgery protocol adherence in patients undergoing elective neuro-oncological craniotomies

Objectives

Enhanced recovery after surgery (ERAS) protocols have reduced the length of hospital stay (LOS) and healthcare costs without increasing adverse outcomes. We describe the impact of adherence to an ERAS protocol for elective craniotomy among neuro-oncology patients at a single institution.

Methods

This retrospective study enrolled adult patients who underwent elective craniotomy and the ERAS protocol at our institute between January 2020 and April 2021. The patients were divided into high- and low-adherence groups depending on their adherence to ≥9 or <9 of the 16 items, respectively. Inferential statistics were used to compare group outcomes, and multivariable logistic regression analysis was used to examine factors related to delayed discharge (LOS>7 days).

Results

Among the 100 patients assessed, median adherence was 8 items (range, 4-16), and 55 and 45 patients were classified into the high- and low-adherence groups, respectively. Age, sex, comorbidities, brain pathology, and operative profiles were comparable at baseline. The high-adherence group showed significantly better outcomes, including shorter median LOS (8 days vs. 11 days; p ​= ​0.002) and lower median hospital costs (131,657.5 baht vs. 152,974 baht; p ​= ​0.005). The groups showed no differences in 30-day postoperative complications or Karnofsky performance status. In the multivariable analysis, high adherence to the ERAS protocol (>50%) was the only significant factor preventing delayed discharge (OR ​= ​0.28; 95% CI ​= ​0.10 to 0.78; p ​= ​0.04).

Conclusions

High adherence to ERAS protocols showed a strong association with short hospital stays and cost reductions. Our ERAS protocol was feasible and safe for patients undergoing elective craniotomy for brain tumors.

Development of an enhanced recovery protocol after laser ablation surgery protocol: a preliminary analysis

Background

Enhanced recovery after surgery (ERAS) programs are a model of care that aim to improve patient outcomes, reduce complications, and facilitate recovery while reducing healthcare-associated costs and admission length. While such programs have been developed in other surgical subspecialties, there have yet to be guidelines published specifically for laser interstitial thermal therapy (LITT). Here we describe the first multidisciplinary ERAS preliminary protocol for LITT for the treatment of brain tumors.

Methods

Between the years 2013 and 2021, 184 adult patients consecutively treated with LITT at our single institution were retrospectively analyzed. During this time, a series of pre, intra, and postoperative adjustments were made to the admission course and surgical/anesthesia workflow with the goal of improving recovery and admission length.

Results

The mean age at surgery was 60.7 years with a median preoperative Karnofsky performance score of 90 ± 13. Lesions were most commonly metastases (50%) and high-grade gliomas (37%). The mean length of stay was 2.4 days, with the average patient being discharged 1.2 days after surgery. There was an overall readmission rate of 8.7% with a LITT-specific readmission rate of 2.2%. Three of 184 patients required repeat intervention in the perioperative period, and there was one perioperative mortality.

Conclusions

This preliminary study shows the proposed LITT ERAS protocol to be a safe means of discharging patients on postoperative day 1 while preserving outcomes. Although future prospective work is needed to validate this protocol, results show the ERAS approach to be promising for LITT.

Benefits of Prehabilitation before Complex Aortic Surgery

The purpose of this narrative review was to detail and discuss the underlying principles and benefits of preoperative interventions addressing risk factors for perioperative adverse events in open aortic surgery (OAS). The term "complex aortic disease" encompasses juxta/pararenal aortic and thoraco-abdominal aneurysms, chronic aortic dissection and occlusive aorto-iliac pathology. Although endovascular surgery has been increasingly favored, OAS remains a durable option, but by necessity involves extensive surgical approaches and aortic cross-clamping and requires a trained multidisciplinary team. The physiological stress of OAS in a fragile and comorbid patient group mandates thoughtful preoperative risk assessment and the implementation of measures dedicated to improving outcomes. Cardiac and pulmonary complications are one of the most frequent adverse events following major OAS and their incidences are correlated to the patient's functional status and previous comorbidities. Prehabilitation should be considered in patients with risk factors for pulmonary complications including advanced age, previous chronic obstructive pulmonary disease, and congestive heart failure with the aid of pulmonary function tests. It should also be combined with other measures to improve postoperative course and be included in the more general concept of enhanced recovery after surgery (ERAS). Although the current level of evidence regarding the effectiveness of ERAS in the setting of OAS remains low, an increasing body of literature has promoted its implementation in other specialties. Consequently, vascular teams should commit to improving the current evidence through studies to make ERAS the standard of care for OAS.

Treatment of patients with metastatic epidural spinal cord compression using an enhanced recovery after surgery program

Purpose: The aims of this study were to introduce a new medical, pathway based on the concept of "enhanced recovery after surgery" (ERAS) for patients with metastatic epidural spinal cord compression (MESCC), and to test whether the ERAS program could improve clinical metrics among such patients. Methods: Data from patients with MESCC (n = 98), collected between December 2016 and December 2019 (Non-ERAS cohort), and from 86 patients with metastatic epidural spinal cord compression collected between January 2020 and December 2022 (ERAS cohort), were retrospectively analyzed. Patients were treated by decompressive surgery combined with transpedicular screw implantation and internal fixation. Patient baseline clinical characteristics were collected and compared between the two cohorts. Surgical outcomes analyzed included operation time; intraoperative blood loss; postoperative length of hospital stay; time to ambulation, regular diet, urinary catheter removal, and radiation therapy; perioperative complications; anxiety; depression; and satisfaction with treatment. Results: No significant differences in clinical characteristics were found between the non-ERAS and enhanced recovery after surgery cohorts (all p > 0.050), indicating that the two cohorts were comparable. Regarding surgical outcomes, the enhanced recovery after surgery cohort had significantly less intraoperative blood loss (p < 0.001); shorter length of postoperative hospital stay (p < 0.001); shorter time to ambulation (p < 0.001), regular diet (p < 0.001), urinary catheter removal (p < 0.001), radiation administration (p < 0.001), and systemic internal therapy (p < 0.001); lower perioperative complication rate (p = 0.024); less postoperative anxiety (p = 0.041); and higher score for satisfaction with treatment (p < 0.001); whereas operation time (p = 0.524) and postoperative depression (p = 0.415) were similar between the two cohorts. Compliance analysis demonstrated that ERAS interventions were successfully conducted in the vast majority of patients. Conclusion: The enhanced recovery after surgery intervention is beneficial to patients with metastatic epidural spinal cord compression, according to data on intraoperative blood loss; length of hospital stay; time to ambulation, regular diet, urinary catheter removal, radiation exposure, and systemic internal therapy; perioperative complication; alleviation of anxiety; and improvement of satisfaction. However, clinical trials to investigate the effect of enhanced recovery after surgery are needed in the future.

A standardized anesthetic/analgetic regimen compared to standard anesthetic/analgetic regimen for patients with high-risk factors undergoing open lumbar spine surgery: a prospective comparative single-center study

The objective of the study is to improve the results of patients undergoing lumbar spine surgery who are at high risk for anesthesia and/or surgical complications. Two independent groups were compared: the study group (SG, n = 40) (standardized neuroanesthetic protocol with multimodal analgesia) and the control group (CG, n = 40) (intravenous anesthesia based on propofol and fentanyl). The data were collected using prospective observation of early and long-term results of lumbar fusion. After 24 months, the level of functional state and quality of life were studied. Patients in the SG did not have statistically significant changes in intraoperative hemodynamics; the best indicators of cognitive functions were noted. The effectiveness of the SG compared with the CG was confirmed by a statistically significantly lower amount of perioperative opioid drugs required (p = 0.01) and a minimal level of incisional pain (p < 0.05). An intergroup comparison of the adverse effects of anesthesia revealed a significantly lower number in the SG (n = 4) compared to the CG (n = 16) (p = 0.004). The number of postoperative surgical complications was comparable (p = 0.72). Intergroup comparison showed improved ODI, SF-36, and the Macnab scale at 24 months after surgery in the SG compared to the CG (p < 0.05). Long-term clinical results correlated with the level of incisional pain in the first three postoperative days. Our standardized neuroanesthetic protocol ensured effective treatment of postoperative incisional pain, significantly decreased the perioperative use of opioids, reduced adverse anesthesia events, and improved long-term clinical results in patients with high risk factors for anesthetic complications who undergoing open lumbar spine surgery.

Analgesic efficacy of inter-semispinal fascial plane block in Patients undergoing Cervical Spine Surgery through Posterior Approach: a randomized controlled trial

BACKGROUND

Posterior cervical spine surgery is commonly performed in elderly patients with significant comorbidities and is considered one of the most painful surgical procedures. Accordingly, perioperative pain management during posterior cervical spine surgery represents a unique challenge for anesthesiologists. Inter-semispinal plane block (ISPB) represents a promising analgesic technique for spine surgery through the blockade of the dorsal rami of the cervical spinal nerves. The present study aimed to investigate the analgesic effect of bilateral ISPB as an opioid-sparing nerve block technique for posterior cervical spine surgeries.

METHODS

This prospective randomized controlled trial enrolled 52 patients planned for cervical spine surgery via the posterior approach. Patients were randomly assigned to one of two groups in a one-to-one ratio, with 26 patients allocated to the block group (ISPB) who received general anesthesia preceded by bilateral ISP using 20 mL 0.25% bupivacaine on each side and the remaining 26 patients allocated to the control group who received general anesthesia only. The primary outcome was total perioperative opioid consumption through two co-primary outcomes, i.e. total amount of fentanyl administered intraoperatively and total morphine consumption during the first 24 hours postoperatively. The secondary outcomes included intraoperative hemodynamic parameters, assessment of numerical rating scores (NRS) during the first 24 hours postoperatively, time to first rescue analgesia and opioid-related side effects.

RESULTS

A significantly lower amount of intraoperative fentanyl was administered in the ISPB group (median, 175 μg; range, 110-220 μg] compared to the control group [median, 290 μg; range 110-350 μg). Patients in the ISPB group consumed significantly lower doses of morphine (median, 7 mg; range, 5-12 mg]) within the first 24 h postoperatively compared to the control group (median, 12 mg; range, 8-21 mg). In addition, NRS values were significantly lower in the ISPB group during the first 12 h postoperatively than in the control group. No significant differences in mean arterial pressure (MAP) or heart rate (HR) were observed between intraoperative time points in the ISPB group. However, a significant increase in MAP was observed during surgery in the control group (p < 0.001). The incidence of opioid side effects such as nausea, vomiting, and sedation was significantly greater in the control group compared to the ISPB group.

CONCLUSIONS

Inter-semispinal plane block (ISPB) represents an effective analgesic technique and reduces opioid consumption in both intra- and postoperative settings. Moreover, the ISPB could significantly decrease opioid-associated side effects.

Clinical Outcomes of Liposomal Bupivacaine Erector Spinae Block in Minimally Invasive Transforaminal Lumbar Interbody Fusion Surgery

BACKGROUND

Postoperative pain is a barrier to early mobility and discharge after lumbar surgery. Liposomal bupivacaine (LB) has been shown to decrease postoperative pain and narcotic consumption after transforaminal lumbar interbody fusions (TLIFs) when injected into the marginal suprafascial/subfascial plane-liposomal bupivacaine (MSSP-LB). Erector spinae plane (ESP) infiltration is a relatively new analgesic technique that may offer additional benefits when performed in addition to MSSP-LB.

OBJECTIVE

To evaluate postoperative outcomes of combining ESP-LB with MSSP-LB compared with MSSP-LB alone after single-level TLIF.

METHODS

A retrospective analysis was performed for patients undergoing single-level TLIFs under spinal anesthesia, 25 receiving combined ESP-LB and MSSP-LB and 25 receiving MSSP-LB alone. The primary outcome was length of hospitalization. Secondary outcomes included postoperative pain score, time to ambulation, and narcotics usage.

RESULTS

Baseline demographics and length of surgery were similar between groups. Hospitalization was significantly decreased in the ESP-LB + MSSP-LB cohort (2.56 days vs 3.36 days, P = .007), as were days to ambulation (0.96 days vs 1.29 days, P = .026). Postoperative pain area under the curve was significantly decreased for ESP-LB + MSSP-LB at 12 to 24 hours (39.37 ± 21.02 vs 53.38 ± 22.11, P = .03) and total (44.46 ± 19.89 vs 50.51 ± 22.15, P = .025). Postoperative narcotic use was significantly less in the ESP-LB + MSSP-LB group at 12 to 24 hours (13.18 ± 4.65 vs 14.78 ± 4.44, P = .03) and for total hospitalization (137.3 ± 96.3 vs 194.7 ± 110.2, P = .04).

CONCLUSION

Combining ESP-LB with MSSP-LB is superior to MSSP-LB alone for single-level TLIFs in decreasing length of hospital stay, time to ambulation, postoperative pain, and narcotic use.

Recommendations for enhanced post-surgical recovery in the spine (REPOC)

INTRODUCTION/OBJECTIVES

Enhanced recovery after surgery (ERAS) constitutes a multimodal approach, based on available scientific evidence, that achieves better patient's functionality, reduces pain, and even lowers financial costs. The present consensus statement proposes the standards for the implementation of ERAS programs to lumbar fusion surgery, a meant benchmark we call REPOC.

METHODOLOGY

A multidisciplinary group of experts was set up ad hoc to review consensus recommendations for lumbar arthrodesis, using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system.

RESULTS

As a result, 23 recommendations were selected throughout the preoperative, intraoperative, and postoperative phases of the surgical procedure. A 29-item checklist was also drawn up to implement REPOC protocols in spinal surgeries.

CONCLUSIONS

This list of recommendations will facilitate the implementation of this multimodal approach as a safe and effective tool for reducing adverse events in our environment.

Projections From Surgical Use Models in Germany Suggest a Rising Number of Spinal Fusions in Patients 75 Years and Older Will Challenge Healthcare Systems Worldwide

BACKGROUND

Spinal fusion is a well-established procedure in the treatment of degenerative spinal diseases. Previous research shows that the use of this operative treatment has been growing in recent decades in industrialized countries and has become one of the most cost-intensive surgical procedures. It seems that in some countries such as Germany-with its large, industrialized, European population-this increase is mainly driven by demographic changes with low fertility rates, increasing life expectancy, and an aging population. Based on current projections, however, Germany faces a population trend that many other countries are likely to follow within a few decades. An increasingly shrinking and aging working population may eventually put the healthcare system under enormous pressure, with greater demands for spinal fusions and associated higher costs. Thus, we aimed to provide reliable projections regarding the future demand for posterior spinal fusion procedures including age- and gender-related trends up to 2060, which will be necessary for future resource planning and possible improvements in actual treatment strategies.

QUESTIONS/PURPOSES

(1) How is the use of posterior spinal fusions in Germany expected to change from 2019 through 2060, if currents trends continue? (2) How is the use of posterior spinal fusions in Germany expected to change depending on patients' age and gender during this time period?

METHODS

Comprehensive nationwide data provided by the Federal Statistical Office, the official institution for documenting all data on operations and procedures performed in Germany, were used to quantify posterior spinal fusion rates as a function of calendar year, age, and gender. Because there is a lack of evidence regarding future trends in the use of posterior spinal fusions, an autoregressive integrated moving average model on historical procedure rates from 2005 to 2019 in relation to official population projections from 2020 to 2060 was chosen to forecast future absolute numbers and incidence rates of this procedure in Germany. Long-term forecasting is more prone to unexpected disruptions than forecasting over short-term periods; however, longer spans facilitate estimates of how trends may challenge future healthcare systems if those trends continue, and thus are useful for research and planning.

RESULTS

The incidence rate of posterior spinal fusion was projected to increase by approximately 83% (95% CI 28% to 139%) to 102% per 100,000 inhabitants (95% CI 71% to 133%) in 2060, with a 1.3-fold higher rate of women undergoing surgery in terms of absolute numbers. The highest increase identified by the model occurred in patients 75 years and older with 38,974 (95% CI 27,294 to 50,653) posterior spinal fusions in 2060, compared with 14,657 in 2019. This trend applied for both women and men, with a 246% (95% CI 138% to 355%) increase in the total number of posterior spinal fusions for women 75 years and older and a 296% (95% CI 222% to 370%) increase for men 75 years and older. At the same time, posterior spinal fusions in all age groups younger than 55 years were projected to follow a constant or even negative trend up to 2060.

CONCLUSION

Our findings suggest that increasing use of posterior spinal fusion, particularly in patients 75 years and older, will challenge healthcare systems worldwide if current trends persist. This study may serve as a model for many other industrialized countries facing similar demographic and procedure-specific developments in the future. This emphasizes the need to focus on frailty research as well as appropriate financial and human resource management. Effective perioperative medical management, multidisciplinary treatment, and interinstitutional protocols are warranted, especially in older patients as we attempt to manage these trends in the future.

Chemoprophylactic Anticoagulation Following Lumbar Surgery Significantly Reduces Thromboembolic Events After Instrumented Fusions, Not Decompressions

STUDY DESIGN

Retrospective cohort.

OBJECTIVE

To quantify any reduction in venous thromboembolic events (VTEs) caused by chemoprophylaxis among lumbar surgery patients.

SUMMARY OF BACKGROUND DATA

Chemoprophylactic anticoagulation (chemoprophylaxis) is used to prevent VTE after lumbar surgery. However, the treatment effect of chemoprophylaxis has not been reported among spine surgery patients, as conventional statistical methods preclude such inferences.

MATERIALS AND METHODS

A total of 1243 consecutive lumbar fusions and 1433 noninstrumented lumbar decompressions performed at our institution over a six-year period were identified, and clinical and demographic data were collected, including on VTE events within 30 days postoperatively. Instrumented lumbar fusions and noninstrumented lumbar surgeries were analyzed separately. Patients who were given chemoprophylaxis (treatment) and controls were matched according to known VTE risk factors, including age, body mass index, sex, diabetes, chronic kidney disease, history of VTE, estimated blood loss, length of surgery, transfusion, whether surgery was staged, and whether surgery used an anterior approach. K-nearest neighbor propensity score matching was performed, and the treatment effect of chemoprophylaxis was calculated.

RESULTS

Unadjusted, there was no difference in the rate of VTE between treatment and controls in either population. Baseline clinical and demographic characteristics differed significantly between treatment and control groups. In all, 575 lumbar fusion patients and 435 noninstrumented lumbar decompression patients were successfully propensity score matched, yielding balanced models (Rubin B <25, 0.5<Rubin R <2.0) and >60% reduction in known bias for both populations. The treatment effect of chemoprophylaxis after lumbar fusion in our patient population was a reduction in VTE incidence from 9.4% to 4.2% ( P <0.05), and propensity score adjusted regression confirmed a reduced odds of VTE with chemoprophylaxis (odds ratio=0.37, P =0.035). The treatment effect was not significant for noninstrumented lumbar decompression patients.

CONCLUSION

Among patients undergoing instrumented lumbar fusions, chemoprophylactic anticoagulation causes a significant reduction in VTE, but causes no significant reduction among patients undergoing noninstrumented lumbar decompression.

Fast-Track for Total Ankle Replacement: A Novel Enhanced Recovery Protocol for Select Patients

BACKGROUND

Enhanced recovery after surgery programs, also called fast-track protocols, were developed and successfully applied in the last decade for hip and knee reconstruction. Specific fast-track protocols have not yet been applied to ankle prostheses. The aim of the study was to develop and validate an enhanced recovery protocol for total ankle replacement (TAR) evaluating the clinical and radiographic results. We hypothesize that on the basis of well-defined pre- and postoperative characteristics, the current knowledge on ankle replacement, and referring to hip and knee reconstruction, it is possible to identify a "patient type" to be safely eligible to a Fast-Track Protocol with at least comparable results and without increasing the complications risk.

METHODS

We identified 8 predictive variables that might affect the outcome of TAR. Those variables were the body mass index, the state of anxiety or depression, the functional preoperative status, ankle equinus, the coronal malalignment, the surgical time, the surgical accessory procedures, and the bone quality. These characteristics were evaluated for each patient with almost validated outcome tools attributing a specific score. Based on the score obtained, the patients were divided into 2 groups: the Standard Protocol group (Control Group) and the Fast-Track Protocol group (Study Group). The main difference between treatment of the 2 groups relates to the use of postoperative plaster casts: in the Fast-Track group the cast was removed the first day after surgery and walking was allowed in sports shoes assisted with crutches, whereas in the Standard Protocol group, the cast was removed after 3 weeks. Clinical and radiographic evaluation was performed for all patients preoperatively and postoperatively every 6 months.

RESULTS

A total of 163 patients received a score between 1 and 5 and were included in the control group (Standard Protocol); 47 patients received a score of 0 and were allocated to the study group (Fast-Track Protocol). Clinically, except for the preoperative American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale score, no statistically significant differences were recorded in the multiple comparisons between the 2 groups. No significant differences were found regarding complications.

CONCLUSION

In selected patients, it is possible to apply an enhanced recovery protocol of rehabilitation, focused on immediate weightbearing and mobilization without any plaster or boot.

Fast-track protocols for patients undergoing spine surgery: a systematic review

BACKGROUND CONTEXT

Fast-track is an evidence-based multidisciplinary strategy for pre-, intra-, and postoperative management of patients during major surgery. To date, fast-track has not been recognized or accepted in all surgical areas, particularly in orthopedic spine surgery where it still represents a relatively new paradigm.

PURPOSE

The aim of this review was provided an evidenced-based assessment of specific interventions, measurement, and associated outcomes linked to enhanced recovery pathways in spine surgery field.

METHODS

We conducted a systematic review in three databases from February 2012 to August 2022 to assess the pre-, intra-, and postoperative key elements and the clinical evidence of fast-track protocols as well as specific interventions and associated outcomes, in patients undergoing to spine surgery.

RESULTS

We included 57 full-text articles of which most were retrospective. Most common fast-track elements included patient's education, multimodal analgesia, thrombo- and antibiotic prophylaxis, tranexamic acid use, urinary catheter and drainage removal within 24 hours after surgery, and early mobilization and nutrition. All studies demonstrated that these interventions were able to reduce patients' length of stay (LOS) and opioid use. Comparative studies between fast-track and non-fast-track protocols also showed improved pain scores without increasing complication or readmission rates, thus improving patient's satisfaction and functional recovery.

CONCLUSIONS

According to the review results, fast-track seems to be a successful tool to reduce LOS, accelerate return of function, minimize postoperative pain, and save costs in spine surgery. However, current studies are mainly on degenerative spine diseases and largely restricted to retrospective studies with non-randomized data, thus multicenter randomized trials comparing fast-track outcomes and implementation are mandatory to confirm its benefit in spine surgery.

Unilateral biportal endoscopic lumbar interbody fusion enhanced the recovery of patients with the lumbar degenerative disease compared with the conventional posterior procedures: A systematic review and meta-analysis

Background

Minimally invasive endoscopic technique is an important component of Enhanced Recovery After Surgery (ERAS) protocol for neurosurgery. In recent years, unilateral biportal endoscopic lumbar interbody fusion (ULIF) has been used in the treatment of lumbar degenerative diseases (LDD). This study aims to investigate whether ULIF could enhance the recovery of patients with LDD compared with the conventional minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) or posterior lumbar interbody fusion (PLIF).

Methods

A comprehensive literature search was performed for relevant studies in PubMed, EMBASE, Web of Science, Cochrane Library database, China National Knowledge Internet, and Wanfang database. Surgical data, clinical outcomes, radiographic outcomes, and surgical complications were compared between patients with LDD who underwent ULIF and those who underwent conventional MI-TLIF or PLIF.

Results

Notably, 12 studies, comprising 981 patients with LDD, were included. Of these patients, 449 underwent ULIF and 532 patients (355 MI-TLIF and 177 PLIF) were treated with conventional procedures. There was no significant difference in the fusion rate, cage subsidence rate, and surgical complications between the ULIF group and the MI-TLIF or PLIF group. Compared with MI-TLIF, the ULIF group presented a significantly reduced estimated blood loss (EBL) (WMD, -106.00; 95% CI -140.99 to -71.10, P < 0.001) and shorter length of hospital stay (LOS) (WMD, -1.27; 95% CI -1.88 to -0.66, P < 0.001); better short-term improvement in ODI (WMD, -2.12; 95% CI -3.53 to -0.72, P = 0.003) and VAS score for back pain (VAS-BP) (WMD, -0.86; 95% CI -1.15 to -0.58, P < 0.001) at 1 month post-operatively. Compared with PLIF, the ULIF group presented a significantly reduced EBL (WMD, -149.22; 95% CI -284.98 to -13.47, P = 0.031) and shorter LOS (WMD, -4.40; 95% CI -8.04 to -0.75, P = 0.018); better short-term improvement in VAS-BP (WMD, -1.07; 95% CI -1.77 to -0.38, P = 0.002) and VAS score for leg pain (VAS-LP) (WMD, -0.40; 95% CI -0.72 to -0.08, P = 0.014) at 1-2 week post-operatively; enhanced short- and long-term improvement in ODI at 1 month post-operatively (WMD, -3.12; 95% CI -5.72 to -0.53, P = 0.018) and the final follow-up (WMD, -1.97; 95% CI -3.32 to -0.62, P = 0.004), respectively.

Conclusion

Compared with conventional MI-TLIF and PLIF, ULIF was associated with reduced EBL, shorter LOS, and comparable fusion rate as well as complication management. Compared with MI-TLIF, a better short-term improvement in VAS-BP and ODI was achieved by ULIF; compared with open PLIF, additional enhanced short-term improvement in VAS-LP and long-term improvement in ODI were observed in ULIF. ULIF could enhance the recovery of patients with LDD compared with conventional posterior procedures.

Frailty Assessment and Prehabilitation Before Complex Spine Surgery in Patients With Degenerative Spine Disease: A Narrative Review

Degenerative spine disease increases in prevalence and may become debilitating as people age. Complex spine surgery may offer relief but becomes riskier with age. Efforts to lessen the physiological impact of surgery through minimally invasive techniques and enhanced recovery programs mitigate risk only after the decision for surgery. Frailty assessments outperform traditional tools of perioperative risk stratification. The extent of frailty predicts complications after spine surgery such as reoperation for infection and 30-day mortality, as well as elements of social cost such as hospital length of stay and discharge to an advanced care facility. Symptoms of spine disease overlap with phenotypic markers of frailty; therefore, different frailty assessment tools may perform differently in patients with degenerative spine disease. Beyond frailty, however, cognitive decline and psychosocial isolation may interact with frailty and affect achievable surgical outcomes. Prehabilitation, which has reduced perioperative risk in colorectal and cardiac surgery, may benefit potential complex spine surgery patients. Typical prehabilitation includes physical exercise, nutrition supplementation, and behavioral measures that may offer symptomatic relief even in the absence of surgery. Nonetheless, the data on the efficacy of prehabilitation for spine surgery remains sparse and barriers to prehabilitation are poorly defined. This narrative review concludes that a frailty assessment-potentially supplemented by an assessment of cognition and psychosocial resources-should be part of shared decision-making for patients considering complex spine surgery. Such an assessment may suffice to prompt interventions that form a prehabilitation program. Formal prehabilitation programs will require further study to better define their place in complex spine care.

Acute Pain Management Pearls: A Focused Review for the Hospital Clinician

Acute pain management is a challenging area encountered by inpatient clinicians every day. While patient care is increasingly complex and costly in this realm, the availability of applicable specialists is waning. This narrative review seeks to support diverse hospital-based healthcare providers in refining and updating their acute pain management knowledge base through clinical pearls and point-of-care resources. Practical guidance is provided for the design and adjustment of inpatient multimodal analgesic regimens, including conventional and burgeoning non-opioid and opioid therapies. The importance of customized care plans for patients with preexisting opioid tolerance, chronic pain, or opioid use disorder is emphasized, and current recommendations for inpatient management of associated chronic therapies are discussed. References to best available guidelines and literature are offered for further exploration. Improved clinician attention and more developed skill sets related to acute pain management could significantly benefit hospitalized patient outcomes and healthcare resource utilization.

Randomized active-controlled study of a single preoperative administration of duloxetine to treat postoperative pain and numbness after posterior lumbar interbody fusion surgery

BACKGROUND

This prospective, randomized, double-blinded, active controlled trial assessed whether a single preoperative administration of 40 mg of duloxetine could decrease postoperative pain and numbness after posterior lumbar interbody fusion surgery (PLIF).

METHODS

Patients with an American Society of Anesthesiologists physical status I or II undergoing PLIF were included. At 2 hours before inducing anesthesia, patients were administered 40 mg duloxetine or 4 mg diazepam (control drug). Postoperative pain and other symptoms were evaluated on the basis of a visual analog scale, amount of fentanyl used, fentanyl dose request times, rate of use of adjunctive analgesics (diclofenac sodium or pentazocine), and lower limb numbness score (0-3) during the first 2 postoperative days.

RESULTS

Forty-six patients were randomly assigned to the duloxetine and diazepam groups (n = 23 each); 6 were lost to follow-up, and analysis was performed on data from 22 patients in the duloxetine group and 18 in the diazepam group. No significant differences were detected in the patient background, postoperative visual analog scale score at rest in the lumbar region and lower limbs, fentanyl use, rate of analgesic adjuvant use, or incidence of side effects. The numbness score in the lower limbs, however, was significantly lower in the duloxetine group.

CONCLUSION

A single preoperative 40-mg dose of duloxetine did not improve postoperative pain after PLIF, but did improve lower limb numbness. Duloxetine may suppress neuropathic pain-like symptoms after PLIF surgery.

Preoperative characteristics are associated with increased likelihood of low early postoperative mobility after adult spinal deformity surgery

BACKGROUND CONTEXT

Low early postoperative mobility (LEPOM) has been shown to be associated with increased length of hospital stay, complication rates, and likelihood of nonhome discharge. However, few studies have examined preoperative characteristics associated with LEPOM in adult spinal deformity (ASD) patients.

PURPOSE

To investigate which preoperative patient characteristics may be associated with LEPOM after ASD surgery.

DESIGN

Retrospective review.

PATIENT SAMPLE

Included were 86 ASD patients with fusion of ≥5 levels for whom immediate-postoperative AM-PAC Basic Mobility Inpatient Short Form (6-Clicks) scores had been obtained.

OUTCOME MEASURES

The primary outcome of this study was the likelihood of LEPOM, defined as an AM-PAC score ≤15, which is associated with inability to stand for more than 1 minute.

METHODS

Significant cutoffs for preoperative characteristics associated with LEPOM were determined via threshold linear regression. Multivariable logistic regression was used to assess the impact of preoperative characteristics on the likelihood of LEPOM.

RESULTS

LEPOM was recorded in 38 patients (44.2%). Threshold regression identified the following cutoffs to be associated with LEPOM: preoperative Patient Reported Outcomes Measurement Information System (PROMIS) scores of ≥68 for Pain, <28.3 for Physical Function, and ≥63.4 for Anxiety; preoperative Oswestry disability index (ODI) score of ≥60; and body mass index (BMI) of ≥35.2. On multivariate analysis, preoperative PROMIS scores of ≥68 for Pain (odds ratio [OR] 5.3, confidence interval [CI] 1.2-22.8, p=.03), <28.3 for Physical Function (OR 10.1, CI 1.8-58.2, p=.01), and ≥63.4 for Anxiety (OR 4.7, CI 1.1-20.8, p=.04); preoperative ODI score ≥60 (OR 38.8, CI 4.0-373.6, p=.002); BMI ≥35.2 (OR 14.2, CI 1.3-160.0, p=.03), and male sex (OR 5.4, CI 1.2-23.7, p=.03) were associated with increased odds of LEPOM.

CONCLUSIONS

Preoperative PROMIS Pain, Physical Function, and Anxiety scores; ODI score; BMI; and male sex were associated with LEPOM. Several of these characteristics are modifiable risk factors and thus may be candidates for optimization before surgery.

Comparison of Perioperative Outcomes in Patients Undergoing Short-Level Lumbar Fusion Surgery After Implementing Enhanced Recovery After Surgery: A Propensity Score Matching Analysis Focusing on Young-Old and Old-Old

Background

There were exponentially increased studies focused on revealing the satisfactory outcomes after implementing enhanced recovery after surgery (ERAS) in patients undergoing lumbar fusion surgery. However, little attention has been paid to the impact of chronologic age alone on perioperative outcomes.

Methods

In the present study, patients were dichotomized into two groups: young-old (65-79 years), and old-old (80 years and older). Given the heterogeneity and age-related comorbidities in this population and the need to compare similar groups, we performed propensity score matching for gender, body mass index (BMI), operation time, American Society of Anesthesiologists (ASA) grade, Charlson Comorbidity Index (CCI), fusion levels and frail status. Perioperative outcomes were compared between two groups.

Results

In our study, we found there were significant discrepancies in length of stay (LOS) (7.17 ± 2.81 vs 8.11 ± 3.57 days, p = 0.031) and postoperative nausea and vomiting (3.7% vs 11.0%, p = 0.038); however, there were no significant differences in C-reactive protein (21.50 ± 26.52 vs 19.22 ± 22.04 mg/L, p = 0.490), overall complication rates (24.8% vs 33.0%, p = 0.179), ambulation time (2.89 ± 1.34 vs 2.55 ± 1.49 days, p = 0.078) or removal of urinary catheter time (2.47 ± 1.44 vs 2.32 ± 1.40 days, p = 0.446).

Conclusion

There were few differences in perioperative outcomes between young-old and old-old groups. Despite similar postoperative complication rates, the old-old group might experience longer LOS when complications occur. More importantly, current outcomes suggested that chronologic age alone does not appear to have the capacity to reflect the tolerance of elderly patients to surgery.

Patient outcomes following implementation of an enhanced recovery after surgery pathway for patients with metastatic spine tumors

BACKGROUND

Metastatic spine tumor surgery consists of palliative operations performed on frail patients with multiple medical comorbidities. Enhanced recovery after surgery (ERAS) programs involve an evidence-based, multidisciplinary approach to improve perioperative outcomes. This study presents clinical outcomes of a metastatic spine tumor ERAS pathway implemented at a tertiary cancer center.

METHODS

The metastatic spine tumor ERAS program launched in April 2019, and data from January 2018 to May 2020 were reviewed. Measured outcomes included the following: hospital length of stay (LOS), time to ambulation, urinary catheter duration, time to resumption of diet, intraoperative fluid intake, estimated blood loss (EBL), and intraoperative and postoperative day 0-5 cumulative opioid use (morphine milligram equivalent [MME]).

RESULTS

A total of 390 patients were included in the final analysis: 177 consecutive patients undergoing metastatic spine tumor surgery enrolled in the ERAS program and 213 consecutive pre-ERAS patients. Although the mean case durations were similar in the ERAS and pre-ERAS cohorts (265 vs. 274 min; p = .22), the ERAS cohort had decreased EBL (157 vs. 215 ml; p = .003), decreased postoperative day 0-5 cumulative mean opioid use (178 vs. 396 MME; p < .0001), earlier ambulation (mean, 34 vs. 57 h; p = .0001), earlier discontinuation of urinary catheters (mean, 36 vs. 56 h; p < .001), and shorter LOS (5.4 vs. 7.5 days; p < .0001).

CONCLUSIONS

The implementation of a multidisciplinary ERAS program designed for metastatic spine tumor surgery led to improved clinical quality metrics, including shorter hospitalizations and significant reductions in opioid consumption.

Knowledge, attitude and application towards fast track surgery among operating room paramedics: a cross-sectional study

BACKGROUND

Fast track surgery has shown its effectiveness to accelerate recovery and gained acceptance in many operations. However, data for paramedics using fast track surgery are limited in China. The aims of our study are to evaluate the knowledge, attitude and application status of fast track surgery in paramedics and to provide suggestions for the better application of fast track surgery.

METHODS

Two Hundred Ninety-one operating room paramedics were investigated by simple random sampling from October 20 to December 20, 2019 time. A self-reported questionnaire was used to collect data with five dimensions: demographic data, cognitive level, knowledge, attitude and application of fast track surgery. Data were analyzed using qualitative and quantitative methods.

RESULTS

19.93% of participants never heard fast track surgery and only 3.32% of participants were very familiar with it. Gender (0.702, 95% CI 0.109-1.294), technical title (0.342, 95% CI 0.126-0.558) and awareness of the concept of fast track surgery (0.471, 95% CI 0.165-0.776) had a correlation with the knowledge level of paramedics towards fast track surgery. In terms of attitude towards fast track surgery, gender (- 1.944, 95% CI -3.830- -0.058), age (0.303, 95% CI 0.021-0.585) and knowledge score of fast track surgery (0.426, 95% CI 0.014-0.838) are related. Half of the paramedics believe the most difficult problem in the application of fast track surgery was the lack of multi-team communication and cooperation.

CONCLUSION

The knowledge of fast track surgery among paramedics in Wuhan is poor, and some paramedics have a negative attitude towards it. As the attitude is positively correlated with the knowledge, it is necessary to improve the knowledge level of fast track surgery among paramedics in Wuhan.

AM-PAC mobility scores predict non-home discharge following adult spinal deformity surgery

BACKGROUND CONTEXT

Adult spinal deformity (ASD) surgery requires an extended recovery period and often non-routine discharge. The Activity Measure for Post-Acute Care (AM-PAC) Basic Mobility Inpatient Short Form (6-Clicks) is a prediction tool, validated for other orthopedic procedures, to assess a patient's ability to mobilize after surgery.

PURPOSE

To assess the thresholds of AM-PAC scores that determine non-home discharge disposition in patients who have undergone ASD surgery.

STUDY DESIGN

Retrospective review PATIENT SAMPLE: Ninety consecutive ASD patients with ≥5 levels fused who underwent surgery from 2015 to 2018, with postoperative AM-PAC scores measured before discharge, were included.

OUTCOME MEASURES

Non-home discharge disposition METHODS: Patients with routine home discharge were compared to those with non-home discharge. Bivariate analysis was first conducted to compare these groups by preoperative demographics, comorbidities, radiographic alignment, surgical characteristics, HRQOLs, and AM-PAC measurements. Threshold linear regression with Bayesian information criteria was utilized to identify the optimal cutoffs for AM-PAC scores associated with increased likelihood of non-home discharge. Finally, multivariable analysis controlling for age, sex, comorbidities, levels fused, perioperative complication, and home support was conducted to assess each threshold.

RESULTS

Thirty-six (40%) of 90 patients analyzed had non-home discharge. On bivariate analysis, first AM-PAC score (13.5 vs. 17), last AM-PAC score (17 vs. 20), and AM-PAC change per day (+.387 vs. +1) were all significantly associated with non-home discharge. Threshold regression identified that cutoffs of ≤15 for first AM-PAC score, <17 for last AM-PAC score, and <+0.625 for daily AM-PAC change were associated with non-home discharge. On multivariable analysis, first AM-PAC score ≤15 (odds ratio [OR] 11.28; confidence interval [CI] 2.96-42.99; p<.001), last AM-PAC score <17 (OR 33.57; CI 5.85-192.82; p<.001), and AM-PAC change per day <+0.625 (OR 6.24; CI 2.01-19.43; p<.001) were all associated with increased odds of non-home discharge.

CONCLUSIONS

First AM-PAC score of 15 or less can help predict non-home discharge. A goal of daily AM-PAC increases of 0.625 points toward a final AM-PAC score of 17 can aid in achieving home discharge. The early AM-PAC mobility threshold of ≤15 may help prepare for non-home discharge, while AM-PAC daily changes per day <0.625 and final AM-PAC <17 may provide goals for mobility improvement during the early postoperative period in order to prevent non-home discharge.
