ABSTRACT

BACKGROUND: Greater pain self-efficacy (PSE) is associated with reduced pain, fewer limitations, and increased quality of life after treatment for orthopedic conditions. The aims of this study were to (1) assess if PSE improves during a visit with an orthopedic surgeon and (2) identify modifiable visit factors that are associated with an increase in PSE. MATERIALS AND METHODS: We performed a prospective observational study of orthopedic clinic visits at a multispecialty clinic from February to May 2022. New patients who presented to one of six orthopedic surgeons were approached for the study. Patients who provided consent completed a pre-visit questionnaire including the Pain Self-Efficacy Questionnaire (PSEQ) and demographic questions. A trained research member recorded the five-item Observing Patient Involvement in Decision Making Instrument (OPTION-5) score, number of questions asked, and visit duration. Immediately after the visit, patients completed a post-visit questionnaire consisting of the PSEQ and Perceived Involvement in Care Scale (PICS). RESULTS: Of 132 patients enrolled, 61 (46%) had improved PSE after the orthopedic visit, with 38 (29%) having improvement above a clinically significant threshold. There were no significant differences between patients with increased PSE and those without increased PSE when comparing the PICS, OPTION-5, questions asked, or visit duration. CONCLUSION: Almost half of the patients had improvement in PSE during an orthopedic visit. The causal pathway to how to improve PSE and the durability of the improved PSE have implications in strategies to improve patient outcomes in orthopedic surgery, such as communication methods and shared decision-making. Future research can focus on studying different interventions that facilitate improving PSE. [Orthopedics. 202x;4x(x):xx-xx.].

ABSTRACT

PURPOSE: In patients with neuromuscular scoliosis undergoing posterior spinal fusion, the S2 alar iliac (S2AI) screw trajectory is a safe and effective method of lumbopelvic fixation but can lead to implant prominence. Here we use 3D CT modeling to demonstrate the anatomic feasibility of the S1 alar iliac screw (S1AI) compared to the S2AI trajectory in patients with neuromuscular scoliosis. METHODS: This retrospective study used CT scans of 14 patients with spinal deformity to create 3D spinal reconstructions and model the insertional anatomy, max length, screw diameter, and potential for implant prominence between 28 S2AI and 28 S1AI screw trajectories. RESULTS: Patients had a mean age of 14.42 (range 8-21), coronal cobb angle of 85° (range 54-141), and pelvic obliquity of 28° (range 4-51). The maximum length and diameter of both screw trajectories were similar. S1AI screws were, on average, 6.3 ± 5 mm less prominent than S2AI screws relative to the iliac crests. S2AI screws were feasible in all patients, while in two patients, posterior elements of the lumbar spine would interfere with S1AI screw insertion. CONCLUSION: In this cohort of patients with neuromuscular scoliosis, we demonstrate that the S1AI trajectory offers comparable screw length and diameter to an S2AI screw with less implant prominence. An S1AI screw, however, may not be feasible in some patients due to interference from the posterior elements of the lumbar spine.

ABSTRACT

BACKGROUND: Patients undergoing lumbar spine surgery have high rates of preoperative opioid use, which is associated with inferior outcomes and higher risks for opioid dependency postoperatively. PURPOSE: Determine whether there are identifiable subgroups of patients that follow distinct patterns in pre- and postoperative opioid dosing. Examine how preoperative patterns in opioid dosing relate to postoperative opioid patterns, opioid cessation, and the risk for adverse events. STUDY DESIGN/SETTING: Retrospective analysis of an administrative claims database (MeritiveTM Marketscan® Research Databases 2007-2015). PATIENT SAMPLE: The 9,768 patients undergoing primary single level lumbar fusion. OUTCOME MEASURES: Primary: daily morphine milligram equivalent (MME) opioid dosing calculated from prescriptions dispensed for 1 year before and after surgery; secondary: 90-day all-cause readmission and complications, 90-day acute postoperative pain, 90-day and 1-year reoperation, surgical costs, length of stay, and discharge disposition. METHODS: Distinct patient subgroups defined by patterns of daily MME pre- and postoperatively were identified via group-based trajectory modeling. Associations between these groups and outcomes were assessed with multivariable logistic regression with risk adjustment for patient and surgical factors. RESULTS: Among primary single level lumbar fusion patients, 59.5% filled an opioid prescription in the 3 months preceding surgery, whereas 40.5% were opioid naïve (Naïve). Five distinct subgroups of daily MME were identified among those filling opioids preoperatively: (1) Naïve to 3m (21.2% of patients): no opioids until 3 months preoperatively, escalating to 15 MME/day; (2) Low to 3m (11.4%): very low or as needed dose until 3 months preoperatively, escalating to 15 MME/day; (3) 6m Rise (6.9%): no opioids until 6 months preoperatively, escalating to >30 MME/day; (4) Medium (9.8%): increased linearly from 10 to 25 MME/day across the year before surgery; (5) High (10.0%): increased linearly from 60 to >80 MME/day across the year before surgery. These five preoperative opioid groups were related to postoperative opioids filled in a dose-response manner. The two preoperative patient groups with chronic Medium to High-dose opioid dosing were associated with increased adverse events, including all-cause readmission, reoperation, and pneumonia, whereas a low baseline group with a large, earlier preoperative rise in opioid dosing (6m Rise) had increased encounters for acute postoperative pain. Postoperatively, only 9.5% of patients did not fill an opioid prescription. Five distinct postoperative subgroups were identified based on their patterns in daily MME: Two groups ceased filling opioids within the year following surgery (33.6% of patients), and three groups declined in opioid dosage following surgery but plateaued at low (0-5 MME/day, 29.1%), medium (10-15 MME/day, 12.0%), or high (70-75 MME/day), 13.1%) doses by 1 year. Patients within the higher preoperative opioid groups were more likely to belong to the postoperative groups that were unable to cease filling opioids. CONCLUSIONS: Identification of a patient's preoperative time trend in daily opioid use may provide significant prognostic value and help guide pain management and risk reduction efforts. LEVEL OF EVIDENCE: III.

ABSTRACT

STUDY DESIGN: Prospective cross-sectional survey. OBJECTIVE: To identify timelines for when athletes may be considered safe to return to varying athletic activities after sustaining cervical spine fractures. BACKGROUND: While acute management and detection of cervical spine fractures have been areas of comprehensive investigation, insight into timelines for when athletes may return to different athletic activities after sustaining such fractures is limited. METHODS: A web-based survey was administered to members of the Association for Collaborative Spine Research that consisted of surgeon demographic information and questions asking when athletes (recreational vs elite) with one of 8 cervical fractures would be allowed to return to play noncontact, contact, and collision sports treated nonoperatively or operatively. The third part queried whether the decision to return to sports was influenced by the type of fixation or the presence of radiculopathy. RESULTS: Thirty-three responses were included for analysis. For all 8 cervical spine fractures treated nonoperatively and operatively, significantly longer times to return to sports for athletes playing contact or collision sports compared with recreational and elite athletes playing noncontact sports, respectively (P< 0.05), were felt to be more appropriate. Comparing collision sports with contact sports for recreational and elite athletes, similar times for return to sports for nearly all fractures treated nonoperatively or operatively were noted. In the setting of associated radiculopathy, the most common responses for safe return to play were "when only motor deficits resolve completely" and "when both motor and sensory deficits resolve completely." CONCLUSIONS: In this survey of spine surgeons from the Association for Collaborative Spine Research, reasonable timeframes for return to play for athletes with 8 different cervical spine fractures treated nonoperatively or operatively varied based on fracture subtype and level of sporting physicality.

ABSTRACT

BACKGROUND: Proximal junctional kyphosis (PJK) is a complication following surgery for adult spinal deformity (ASD) possibly ameliorated by polymethyl methacrylate (PMMA) vertebroplasty of the upper instrumented vertebrae (UIV). This study quantifies PJK following surgical correction bridging the thoracolumbar junction ± PMMA vertebroplasty. METHODS: ASD patients from 2013 to 2020 were retrospectively reviewed and included with immediate postoperative radiographs and at least one follow-up radiograph. PMMA vertebroplasty at the UIV and UIV + 1 was performed at the surgeons' discretion. RESULTS: Of 102 patients, 56% received PMMA. PMMA patients were older (70 ± 8 vs. 66 ± 10, p = 0.021), more often female (89.3% vs. 68.2%, p = 0.005), and had more osteoporosis (26.8% vs. 9.1%, p = 0.013). 55.4% of PMMA patients developed PJK compared to 38.6% of controls (p = 0.097), and the rate of PJK development was not different between groups in univariate survival models. There was no difference in PJF (p > 0.084). Reoperation rates were 7.1% in PMMA versus 11.4% in controls (p = 0.501). In multivariable models, PJK development was not associated with the use of PMMA vertebroplasty (HR 0.77, 95% CI 0.38-1.60, p = 0.470), either when considered overall in the cohort or specifically in those with poor bone quality. PJK was significantly predicted by poor bone quality irrespective of PMMA use (HR 3.81, p < 0.001). CONCLUSIONS: In thoracolumbar fusions for adult spinal deformity, PMMA vertebroplasty was not associated with reduced PJK development, which was most highly associated with poor bone quality. Preoperative screening and management for osteoporosis is critical in achieving an optimal outcome for these complex operations. LEVEL OF EVIDENCE: 4, retrospective non-randomized case review.

ABSTRACT

PURPOSE: It is unclear if intra-wound vancomycin powder significantly reduces the infection rate for uninstrumented spine surgery. The purpose of this study is to compare the rate of surgical site infection (SSI) in uninstrumented spine surgery that used vancomycin powder against controls. METHODS: A search was performed on PUBMED/MEDLINE, Cochrane Database and Embase on 14 October 2022. Search keywords were "vancomycin, spine surgery, uninstrumented and spinal surgery." Instrumented cases were excluded. Type of surgery, type of treatment and incidence of infection among experimental or control were recorded. RESULTS: 288 articles were obtained from a literature search. 16 studies met inclusion criteria. 6/16 studies that reported on the infection rate using vancomycin were obtained. There were 1376 control cases with 20 cases of post-operative infection (1.45% overall). There were 795 cases that received prophylactic intra-wound vancomycin powder with 10 cases of infection reported (1.26%). There was no significant difference in infections between cases that received vancomycin compared to control. On subgroup analysis, studies that had a high rate of infection (Strom and Cannon) had a significant difference on the rate of infection with the use of vancomycin compared to control. DISCUSSION AND CONCLUSION: The current study was unable to conclude that vancomycin decreased the rate of surgical site infections. Vancomycin use may be useful in populations that have a high rate of infection. Limitations in this study include the small number of studies that report on the use of vancomycin on uninstrumented spine surgery.

ABSTRACT

Human skeletal stem cells (hSSCs) hold tremendous therapeutic potential for developing new clinical strategies to effectively combat congenital and age-related musculoskeletal disorders. Unfortunately, refined methodologies for the proper isolation of bona fide hSSCs and the development of functional assays that accurately recapitulate their physiology within the skeleton have been lacking. Bone marrow-derived mesenchymal stromal cells (BMSCs), commonly used to describe the source of precursors for osteoblasts, chondrocytes, adipocytes and stroma, have held great promise as the basis of various approaches for cell therapy. However, the reproducibility and clinical efficacy of these attempts have been obscured by the heterogeneous nature of BMSCs due to their isolation by plastic adherence techniques. To address these limitations, our group has refined the purity of individual progenitor populations that are encompassed by BMSCs by identifying defined populations of bona fide hSSCs and their downstream progenitors that strictly give rise to skeletally restricted cell lineages. Here, we describe an advanced flow cytometric approach that utilizes an extensive panel of eight cell surface markers to define hSSCs; bone, cartilage and stromal progenitors; and more differentiated unipotent subtypes, including an osteogenic subset and three chondroprogenitors. We provide detailed instructions for the FACS-based isolation of hSSCs from various tissue sources, in vitro and in vivo skeletogenic functional assays, human xenograft mouse models and single-cell RNA sequencing analysis. This application of hSSC isolation can be performed by any researcher with basic skills in biology and flow cytometry within 1-2 days. The downstream functional assays can be performed within a range of 1-2 months.

ABSTRACT

BACKGROUND CONTEXT: Although spine procedures have historically been performed inpatient, there has been a recent shift to the outpatient setting for selected cases due to increased patient satisfaction and reduced cost. Effective postoperative pain management while limiting over-prescribing of opioids, which may lead to persistent opioid use, is critical to performing spine surgery in the outpatient setting. PURPOSE: To assess if there is an increased risk for new, persistent opioid use between inpatient and outpatient spine procedures. STUDY DESIGN: Retrospective analysis using national administrative claims database. PATIENT SAMPLE: A total of 390,049 opioid-naïve patients with a perioperative opioid prescription who underwent an inpatient or outpatient spine surgery. OUTCOME MEASURES: Patients with perioperative opioid prescriptions who filled ≥ 1 opioid prescription between 90- and 180-days following surgery were defined as new, persistent opioid users. METHODS: We utilized a claims database to identify opioid-naïve patients who underwent lumbar or cervical fusion, total disc arthroplasty, or decompression procedures. We constructed a multivariable logistic regression to evaluate the association between inpatient versus outpatient surgery and the development of new, persistent opioid use while adjusting for several patient factors. RESULTS: A total of 19,205 (11.7%) inpatient and 18,546 (8.2%) outpatient patients developed new, persistent opioid use. Outpatient lumbar and cervical spine surgery patients were significantly less likely to develop new, persistent opioid use following surgery compared to inpatient spine surgery patients (OR = 0.71 [95% confidence interval {CI}: 0.69, 0.73], p < .001). Average morphine milligram equivalents (MMEs) (inpatient = 1,476 MME +/- 22.7, outpatient = 1,072 MME +/- 18.5, p < .001) and average MMEs per day (inpatient = 91.6 MME +/- 0.32, outpatient = 77.7 MME +/- 0.28, p < .001) were lower in the outpatient cohort compared to the inpatient. CONCLUSION: Our results support the shift from inpatient to outpatient spine procedures, as outpatient procedures were not associated with an increased risk for new, persistent opioid use. As more patients become candidates for outpatient spine surgery, predictors of new, persistent opioid use should be considered during risk stratification. LEVEL OF EVIDENCE: Level III Prognostic Study. MINI ABSTRACT: We utilized a national administrative claims database to identify opioid-naïve patients who underwent common spine procedures. Outpatient lumbar and cervical spine surgery patients were significantly less likely to be new, persistent opioid users following surgery compared to inpatient spine surgery patients. Our results support the shift to outpatient spine procedures.

ABSTRACT

INTRODUCTION: Orthobiologics are increasingly used to augment healing of tissues. Despite growing demand for orthobiologic products, many health systems do not enjoy substantial savings expected with high-volume purchases. The primary goal of this study was to evaluate an institutional program designed to (1) prioritize high-value orthobiologics and (2) incentivize vendor participation in value-driven contractual programs. METHODS: A three-step approach was used to reduce costs through optimization of orthobiologics supply chain. First, surgeons with orthobiologics expertise were engaged in key supply chain purchasing decisions. Second, eight orthobiologics formulary categories were defined. Capitated pricing expectations were established for each product category. Capitated pricing expectations were established for each product using institutional invoice data and market pricing data. In comparison with similar institutions, products offered by multiple vendors were priced at a lower benchmark (10th percentile of market price) than more rare products priced at the 25th percentile of the market price. Pricing expectations were transparent to vendors. Third, a competitive bidding process required vendors to submit pricing proposals for products. Clinicians and supply chain leaders jointly awarded contracts to vendors that met pricing expectations. RESULTS: Compared with our projected estimate of $423,946 savings using capitated product prices, our actual annual savings was $542,216. Seventy-nine percent of savings came from allograft products. Although the number of total vendors decreased from 14 to 11, each of the nine returning vendors received a larger, three-year institutional contract. Average pricing decreased across seven of the eight formulary categories. DISCUSSION: This study demonstrates a three-step replicable approach to increase institutional savings for orthobiologic products, engaging clinician experts, and strengthening relationships with select vendors. Vendor consolidation permits a symbiotic win-win relationship: Health systems achieve increased value by reducing unnecessary complexity of multiple contracts, and vendors obtain larger contracts with increased market share. LEVEL OF EVIDENCE: Level IV study.

ABSTRACT

OBJECTIVE: There are few prior reports of acute pelvic instrumentation failure in spinal deformity surgery. The objective of this study was to determine if a previously identified mechanism and rate of pelvic fixation failure were present across multiple institutions, and to determine risk factors for these types of failures. METHODS: Thirteen academic medical centers performed a retrospective review of 18 months of consecutive adult spinal fusions extending 3 or more levels, which included new pelvic screws at the time of surgery. Acute pelvic fixation failure was defined as occurring within 6 months of the index surgery and requiring surgical revision. RESULTS: Failure occurred in 37 (5%) of 779 cases and consisted of either slippage of the rods or displacement of the set screws from the screw tulip head (17 cases), screw shaft fracture (9 cases), screw loosening (9 cases), and/or resultant kyphotic fracture of the sacrum (6 cases). Revision strategies involved new pelvic fixation and/or multiple rod constructs. Six patients (16%) who underwent revision with fewer than 4 rods to the pelvis sustained a second acute failure, but no secondary failures occurred when at least 4 rods were used. In the univariate analysis, the magnitude of surgical correction was higher in the failure cohort (higher preoperative T1-pelvic angle [T1PA], presence of a 3-column osteotomy; p < 0.05). Uncorrected postoperative deformity increased failure risk (pelvic incidence-lumbar lordosis mismatch > 10°, higher postoperative T1PA; p < 0.05). Use of pelvic screws less than 8.5 mm in diameter also increased the likelihood of failure (p < 0.05). In the multivariate analysis, a larger preoperative global deformity as measured by T1PA was associated with failure, male patients were more likely to experience failure than female patients, and there was a strong association with implant manufacturer (p < 0.05). Anterior column support with an L5-S1 interbody fusion was protective against failure (p < 0.05). CONCLUSIONS: Acute catastrophic failures involved large-magnitude surgical corrections and likely resulted from high mechanical strain on the pelvic instrumentation. Patients with large corrections may benefit from anterior structural support placed at the most caudal motion segment and multiple rods connecting to more than 2 pelvic fixation points. If failure occurs, salvage with a minimum of 4 rods and 4 pelvic fixation points can be successful.

ABSTRACT

BACKGROUND: Understanding patient-specific trends in costs and healthcare resource utilization (HCRU) surrounding lumbar spine surgery is critically needed to better inform surgical decision making and the development of targeted interventions. PURPOSE: 1) Identify subgroups of patients following distinct patterns in direct healthcare payments pre- and postoperatively, 2) determine whether these patterns are associated with patient and surgical factors, and 3) examine whether preoperative payment patterns are related to postoperative payments, healthcare resource utilization (HCRU), and adverse events. STUDY DESIGN/SETTING: Retrospective analysis of an administrative claims database (IBM Marketscan Research Databases 2007-2015). PATIENT SAMPLE: Adults undergoing primary single-level decompression surgery for lumbar stenosis (n=12,394). OUTCOME MEASURES: Direct healthcare payments, HCRU payments (15 categories), 90-day complications and all-cause readmission, 2-year reoperation METHODS: Group-based trajectory modeling is an application of finite mixture modeling that is able to identify meaningful subgroups within a population that follow distinct developmental trajectories over time. We used this technique to identify subgroups of patients following distinct profiles in preoperative direct healthcare payments. A separate analysis was performed to identify distinct profiles in payments postoperatively. Patient and surgical factors associated with these payment profiles were assessed with multinomial logistic regression, and associations with adverse events were assessed with risk-adjusted multivariable logistic regression. RESULTS: We identified 4 preoperative patient payment subgroups following distinct profiles in payments: Pre-Low (5.8% of patients), Pre-Early-Rising (4.8%), Pre-Medium (26.1%), and Pre-High (63.3%). Postoperatively, 3 patient subgroups were identified: Post-Low (8.9%), Post-Medium (29.6%), and Post-High (61.4%). Patients following the higher-cost pre- and postoperative payment profiles were older, more likely female, and had a greater physical and mental comorbidity burden. With each successively higher preoperative payment profile, patients were increasingly likely to have high postoperative payments, use more HCRU (particularly high-cost services such as inpatient admissions, ER, and SNF/IRF care), and experience postoperative adverse events. Following risk adjustment for patient and surgical factors, patients following the Pre-High payment profile had 209.5 (95% CI: 144.2, 309.7; p<.001) fold greater odds for following the Post-High payment profile, 1.8 (1.3, 2.5; p=.003) fold greater odds for 90-day complications, and 1.7 (1.2, 2.6; p=.035) fold greater odds for 2-year reoperation relative to patients following the Pre-Low payment profile. CONCLUSIONS: There are identifiable subgroups of patients who follow distinct profiles in direct healthcare payments surrounding lumbar decompression surgery. These payment profiles are related to patient age, sex, and physical and mental comorbidities. Notably, preoperative payment profiles may provide prognostic value, as they are associated with postoperative costs, HCRU, and adverse events. LEVEL OF EVIDENCE: III.

ABSTRACT

The influence of health literacy on involvement in decision-making in orthopedic surgery has not been analyzed and could inform processes to engage patients. The goal of this study was to determine the relationship between health literacy and the patient's preferred involvement in decision-making. We conducted a cross-sectional observational study of patients presenting to a multispecialty orthopedic clinic. Patients completed the Literacy in Musculoskeletal Problems (LiMP) survey to evaluate their health literacy and the Control Preferences Scale (CPS) survey to evaluate their preferred level of involvement in decision-making. Statistical analysis was performed with Pearson's correlation and multivariable logistic regression. Thirty-seven percent of patients had limited health literacy (LiMP score <6). Forty-eight percent of patients preferred to share decision-making with their physician equally (CPS score=3), whereas 38% preferred to have a more active role in decision-making (CPS score≤2). There was no statistically significant correlation between health literacy and patient preference for involvement in decision-making (r=0.130; P=.150). Among patients with orthopedic conditions, there is no significant relationship between health literacy and preferred involvement in decision-making. Results from studies in other specialties that suggest that limited health literacy is associated with a preference for less involvement in decision-making are not generalizable to orthopedic surgery. Efforts to engage patients to be informed and participatory in decision-making through the use of decision aids and preference elicitation tools should be directed toward variation in preference for involvement in decision-making, but not toward patient health literacy.

ABSTRACT

ABSTRACT: One of the core foundations of leadership is communication. This past pandemic year gave us lessons in how to improve communication during uncertain times as well as examples of strong leadership in the public sphere. The AOA has formulated important Leadership Principles to guide future educational offerings. I will discuss the importance of these Leadership Principles and give examples of how we can apply these principles.

ABSTRACT

ABSTRACT: The ability to train an orthopaedic resident in all aspects of orthopaedics in 5 years has become increasingly difficult due to the growth in knowledge and techniques, work-hour restrictions, and reduced resident autonomy. It has become nearly universal for our residents to complete at least 1 subspecialty fellowship prior to entering practice. In some subspecialties, the skills necessary to practice competently have become difficult to master. Simply adding to the current length of training may not address these issues effectively and would add to the economic cost of residency training. Novel training pathways that allow residents to focus earlier and in greater depth on their intended subspecialty while maintaining general orthopaedic competencies can be created without lengthening training. It is time to initiate discussions about these possibilities.

ABSTRACT

BACKGROUND CONTEXT: Improved understanding of the pre- and postoperative trends in costs and healthcare resource utilization (HCRU) is needed to better inform patient expectations and aid in the development of strategies to minimize the significant healthcare burden associated with lumbar spine surgery. PURPOSE: Examine the time course of costs and HCRU in the 2 years preceding and following elective lumbar spine surgery for stenosis in a large national claims cohort. STUDY DESIGN/SETTING: Retrospective analysis of an administrative claims database (IBM® Marketscan® Research Databases 2007-2015). PATIENT SAMPLE: Adult patients undergoing elective primary single-level lumbar surgery for stenosis with at least 2 years of continuous health plan enrollment pre- and postoperatively. OUTCOME MEASURES: Functional measures, including monthly rates of HCRU (15 categories), monthly gross covered payments (including payments made by the health plan and deductibles and coinsurance paid by the patient) overall, by HCRU category, and by spine versus non-spine-related. METHODS: All available patients were utilized for analysis of HCRU. For analysis of payments, only patients on noncapitated health plans providing accurate financial information were analyzed. Payments were converted to 2015 United States dollars using the medical care component of the consumer price index. Trends in payments and HCRU were plotted on a monthly basis pre- and post-surgery and assessed with regression models. Relationships with demographics, surgical factors, and comorbidities were assessed with multivariable repeated measures generalized estimating equations. RESULTS: Median monthly healthcare payments 2 years prior to surgery were $275 ($22, $868). Baseline HCRU at 2 years preoperatively was stable or only gradually rising (office visits, prescription drug use), but began an increasingly steep rise in many categories 6 to 12 months prior to surgery. Monthly payments began an increasingly steep rise 6 months prior to surgery, reaching a peak of $1,402 ($634, $2,827) in the month prior to surgery. This was driven by an increase in radiology, office visits, PT, injections, prescription medications, ER encounters, and inpatient admissions. Payments dropped dramatically immediately following surgery. Over the remainder of the 2 years, the median total payments declined only slightly, as a continued decline in spine-related payments was offset by gradually increased non-spine related payments as patients aged. By 2 years postoperatively, the percentage of patients using PT and injections returned to within 1% of the baseline levels observed 2 years preoperatively; however, spine-related prescription medication use remained elevated, as did other categories of HCRU (radiology, office visits, lab/diagnostic services, and also rare events such as inpatient admissions, ER encounters, and SNF/IRF). Patients with a fusion component to their surgeries had higher payments and HCRU preoperatively, and this did not resolve postoperatively. Variations in payments and HCRU were also evident among plan types, with patients on comprehensive medical plans-predominantly employer-sponsored supplemental Medicare coverage-utilizing more inpatient, ER, and inpatient rehabilitation & skilled nursing facilities. Patients on high-deductible plans had fewer payments and HCRU across all categories; however, we are unable to distinguish whether this is because they used fewer of these services or if they were paying for these services out of pocket without submitting to the payer. By 2 years postoperatively, 51% of patients had no spine-related monthly payments, while 33% had higher and 16% had lower monthly payments relative to 2 years preoperatively. CONCLUSIONS: This is the first study to characterize time trends in direct healthcare payments and HCRU over an extended period preceding and following spine surgery. Differences among plan types potentially highlight disparities in access to care and plan-related financial mediators of patients' healthcare resource utilization.

ABSTRACT

STUDY DESIGN: Retrospective cohort. OBJECTIVES: Delayed ejaculation (DE) is a distressing condition characterized by a notable delay in ejaculation or complete inability to achieve ejaculation, and there are no existing reports of DE following lumbar spine surgery. Inspired by our institutional experience, we sought to assess national rates of DE following surgery of the lumbar spine. METHODS: We queried the Optum De-identified Clinformatics Database for adult men undergoing surgery of the lumbar spine between 2003 and 2017. The primary outcome was the development of DE within 2 years of surgery. Multivariable logistic regression was performed to identify factors associated with the development of DE. RESULTS: We identified 117 918 men who underwent 162 646 lumbar spine surgeries, including anterior lumbar interbody fusion (ALIF), posterior lumbar fusion (PLF), and more. The overall incidence of DE was 0.09%, with the highest rate among ALIF surgeries at 0.13%. In multivariable analysis, the odds of developing DE did not vary between anterior/lateral lumbar interbody fusion, PLF, and other spine surgeries. A history of tobacco smoking (OR = 1.47, 95% CI 1.00-2.16, P = .05) and obesity (OR = 1.56, 95% CI 1.00-2.44, P = .05) were associated with development of DE. CONCLUSIONS: DE is a rare but distressing complication of thoracolumbar spine surgery, and patients should be queried for relevant symptoms at postoperative visits when indicated.

ABSTRACT

STUDY DESIGN: Cross-sectional, international survey. OBJECTIVES: To identify factors influencing pharmacologic anticoagulation initiation after spine surgery based on the AOSpine Anticoagulation Global Survey. METHODS: This survey was distributed to the international membership of AOSpine (n = 3805). A Likert-type scale described grade practice-specific factors on a scale from low (1) to high (5) importance, and patient-specific factors a scale from low (0) to high (3) importance. Analysis was performed to determine which factors were significant in the decision making surrounding the initiation of pharmacologic anticoagulation. RESULTS: A total of 316 spine surgeons from 64 countries completed the survey. In terms of practice-specific factors considered to initiate treatment, expert opinion was graded the highest (mean grade ± SD = 3.2 ± 1.3), followed by fellowship training (3.2 ± 1.3). Conversely, previous studies (2.7 ± 1.2) and unspecified guidelines were considered least important (2.6 ± 1.6). Patient body mass index (2.0 ± 1.0) and postoperative mobilization (2.3 ± 1.0) were deemed most important and graded highly overall. Those who rated estimated blood loss with greater importance in anticoagulation initiation decision making were more likely to administer thromboprophylaxis at later times (hazard ratio [HR] = 0.68-0.71), while those who rated drain output with greater importance were likely to administer thromboprophylaxis at earlier times (HR = 1.32-1.43). CONCLUSION: Among our global cohort of spine surgeons, certain patient factors (ie, patient mobilization and body mass index) and practice-specific factors (ie, expert opinion and fellowship training) were considered to be most important when considering anticoagulation start times.

ABSTRACT

STUDY DESIGN: This was a retrospective comparative study. OBJECTIVE: The objective of this study was to assess the effect of increased age on perioperative and postoperative complication rates, reoperation rates, and patient-reported pain and disability scores after lateral lumbar interbody fusion (LLIF). SUMMARY OF BACKGROUND DATA: LLIF was developed to minimize soft tissue trauma and reduce the risk of vascular injury; however, there is little evidence regarding the effect of advanced age on outcomes of LLIF. METHODS: Patients who underwent LLIF from 2009 to 2019 at one institution with a minimum 6-month follow-up were retrospectively reviewed. Patients less than 18 years old with musculoskeletal tumor or trauma were excluded. The primary outcome was the preoperative to postoperative change in the Numeric Pain Rating Scale (NPRS) for back pain. Operative time, estimated blood loss, length of stay, perioperative and 90-day complications, unplanned readmissions, reoperations, and change in Oswestry Disability Index were also evaluated. Relationships with age were assessed both with age as a continuous variable and segmenting by age below 70 versus 70+. RESULTS: In total, 279 patients were included. The median age was 65±13 years and 159 (57%) were female. Age was not related to improvements in back NPRS and Oswestry Disability Index. Operative time, estimated blood loss, length of stay, perioperative and 90-day complications, unplanned readmissions, reoperations, and radiographic fusion rate also were not related to age. After multivariable risk adjustment, increasing age was associated with greater improvements in back NPRS. The decrease in back NPRS was 0.68 (95% confidence interval: 0.14, 1.22; P=0.014) points greater for every 10-year increase in age. Age was not associated with rates of complication, readmission, or reoperation. CONCLUSIONS: LLIF is a safe and effective procedure in the elderly population. Advanced age is associated with larger improvements in preoperative back pain. Surgeons should consider the benefits of LLIF and other minimally invasive techniques when evaluating elderly candidates for lumbar fusion. LEVEL OF EVIDENCE: Level III.

ABSTRACT

PURPOSE: Patient-reported outcome measures are tools for evaluating symptoms, magnitude of limitations, baseline health status, and outcomes from the patient's perspective. Healthcare professional organizations and payers increasingly recommend PROMs for clinical care, but there lacks guidance regarding effective communication of PROMs with orthopedic surgery patients. This qualitative study aimed to identify (1) patient attitudes toward the use and communication of PROMs, and (2) what patients feel are the most relevant or important aspects of PROM results to discuss with their physicians. METHODS: Participants were recruited from a multispeciality orthopedic clinic. Three PROMs: the EuroQol-5 Dimension, the Patient-Specific Functional Scale, and the Patient-Reported Outcome Measurement Information System Physical Function Computer Adaptive Test were shown and a semi-structured interview was conducted to elicit PROMs attitudes and preferences. Interviews were transcribed and inductive-deductively coded. Coded excerpts were aggregated to (1) identify major themes and (2) analyze how themes interacted. RESULT: Three themes emerged: (1) Beliefs toward the purpose of PROMs, (2) PROMs as a reflection of self, and (3) PROMs to facilitate communication and guide healthcare decisions. These themes informed a framework outlining the patient perspective on communicating PROMs during clinical care. CONCLUSION: Patient attitudes toward the use and communication of PROMs start with the incorporation of patient beliefs, which can facilitate or act as a barrier to engagement. Patients should ideally believe that PROMs are an accurate reflection of personal health state before incorporation into care. Clinicians should endeavor to communicate the purpose of a chosen PROM in line with a patient's unique needs and what they feel is most relevant to their own care. Aspects of PROMs results which may be helpful to address include providing context for what scores mean and how they are calculated, and using scores as a way to weigh risks and benefits of treatment and tracking progress over time. Future research can focus on the effect of communication strategies on patient outcomes and engagement in care.

ABSTRACT

BACKGROUND: Previous research has shown that diabetes mellitus (DM) is associated with postoperative complications, including surgical site infections (SSIs). However, evidence for the association between diabetes control and postoperative complications in patients with DM is mixed. Prior studies relied on a single metric for defining uncontrolled DM, which does not account for glycemic variability, and it is unknown whether a more comprehensive assessment of diabetes control is associated with postoperative complications. QUESTIONS/PURPOSES: (1) Is there a difference in the incidence of SSI after lumbar spine fusion in patients with uncontrolled DM, defined with a comprehensive assessment of glycemic control, compared with patients with controlled DM? (2) Is there a difference in the incidence of other select postoperative complications after lumbar spine fusion in patients with uncontrolled DM compared with patients with controlled DM? (3) Is there a difference in total reimbursements between these groups? METHODS: We used the PearlDiver Patient Records Database, a national administrative claims database that provides access to the full continuum of perioperative care. We included 46,490 patients with DM undergoing posterior lumbar fusion with instrumentation. Patients were required to be continuously enrolled in the database for at least 1 year before and 90 days after the index procedure. Patients were divided into uncontrolled and controlled DM cohorts, as defined by ICD-9 diagnostic codes. These are based on a comprehensive assessment of glycemic control, including consideration of patient self-monitoring of blood glucose levels, hemoglobin A1c, and the presence/severity of diabetes-related comorbidities. The cohorts differed only by age, insurance type, and Elixhauser comorbidity score. The primary outcome was the incidence of SSI, divided into superficial and deep, within 90 days postoperatively. Secondary complications included the incidence of cerebrovascular events, acute kidney injury, pulmonary embolism, pneumonia, urinary tract infection, blood transfusion, and total reimbursements. These are the sum of reimbursements occurring within 90 days of surgery, which capture the total professional and facility cost burden to the health payer (such as the insurer). We constructed multivariable logistic regression models to adjust for the effects of age, insurance type, and comorbidities. RESULTS: After adjusting for potentially confounding variables including age, insurance type, and comorbidities, we found that patients with uncontrolled DM had an odds ratio for deep SSI of 1.52 (95% confidence interval 1.16 to 1.95; p = 0.002). Similarly, patients with uncontrolled DM had adjusted odds ratios of 1.25 (95% CI 1.01 to 1.53; p = 0.03) for cerebrovascular events, 1.36 (95% CI 1.18 to 1.57; p < 0.001) for acute kidney injury, 1.55 (95% CI 1.16 to 2.04; p = 0.002) for pulmonary embolism, 1.30 (95% CI 1.08 to 1.54; p = 0.004) for pneumonia, 1.33 (95% CI 1.19 to 1.49; p < 0.001) for urinary tract infection, and 1.27 (95% CI 1.04 to 1.53; p = 0.02) for perioperative transfusion. Patients with uncontrolled DM had higher median 90-day total reimbursements than patients with controlled DM: USD 27,915 (interquartile range 5472 to 63,400) versus USD 10,263 (IQR 4101 to 49,748; p < 0.001). CONCLUSION: Our findings encourage surgeons to take a full diabetic history beyond the HbA1c value, including any self-monitoring of glucose measurements, time in acceptable range for continuous glucose monitors, and/or consideration of the presence/severity of diabetes-related complications before lumbar spine fusion, as HbA1c does not fully capture glycemic control or variability. We emphasize that uncontrolled DM is a clinical, rather than laboratory, diagnosis. Comprehensive diabetes histories should be incorporated into existing preoperative diabetes care pathways and elective surgery could be deferred to improve glycemic control. Future development of an index measure incorporating multidimensional measures of diabetes control (such as continuous or self-glucose monitoring, diabetes-related comorbidities) is warranted. LEVEL OF EVIDENCE: Level III, therapeutic study.
