Systematic review and meta-analysis for the impact of rod materials and sizes in the surgical treatment of adult spine deformity.

PURPOSE: To assess clinical and safety outcomes associated with different rod materials and diameters in adult spinal deformity (ASD) surgery. METHODS: A systematic literature review and meta-analysis evaluated ASD surgery using pedicle screw fixation systems with rods of different materials and sizes. Postoperative outcomes (i.e., Cobb, sagittal vertical axis, and pelvic tilt angle) and complications (i.e., pseudarthrosis and rod breakage) were assessed. Random effects models (REMs) pooled data for outcomes reported in ≥ 2 studies. RESULTS: Among 50 studies evaluating ASD surgery using pedicle screw fixation systems, 17 described rod material/diameter. Postoperative outcomes did not statistically differ between cobalt-chromium (CoCr) vs. titanium (Ti) rods (n = 2 studies; mean [95% confidence interval (CI)] sagittal vertical axis angle: CoCr 37.00° [18.58°-55.42°] and Ti 32.58° [24.62°-40.54°]; mean [95% CI] pelvic tilt angle: CoCr 26.20° [22.87°-29.53°] and Ti 20.15° [18.0°-22.31°]). The pooled proportion (95% CI) of pseudarthrosis was 15% (7-22%) for CoCr and 12% (- 8-32%) for stainless steel (SS) (n = 2 studies each; Chi2 = 0.07, p = 0.79). The pooled proportion (95% CI) of broken rods was 12% (1-22%) for Ti (n = 3 studies) and 10% (2-19) for CoCr (n = 1 study). Among 6.0-6.35 mm rods, the pooled (95% CI) postoperative Cobb angle (n = 2) was 12.01° (9.75°-14.28°), sagittal vertical axis angle (n = 4) was 35.32° (30.02°-40.62°), and pelvic tilt angle was 21.11° (18.35°-23.86°). CONCLUSIONS: For ASD patients undergoing posterior fixation and fusion, there are no statistically significant differences in postoperative outcomes or complications among rods of varying materials and diameters. Benchmark postsurgical outcomes and complication rates by rod material and diameter are provided. LEVEL OF EVIDENCE: III.

Systematic review and meta-analysis for the impact of rod materials and sizes in the surgical treatment of adolescent idiopathic scoliosis.

PURPOSE: To assess surgical and safety outcomes associated with different rod materials and diameters in adolescent idiopathic scoliosis (AIS) surgery. METHODS: A systematic literature review and meta-analysis evaluated the surgical management of AIS patients using pedicle screw fixation systems (i.e., posterior rods and pedicle screws) with rods of different materials and sizes. Postoperative surgical outcomes (e.g., kyphosis and coronal correction) and complications (i.e., hyper/hypo-lumbar lordosis, proximal junctional kyphosis, revisions, reoperations, and infections) were assessed. Random-effects models (REMs) pooled data for outcomes reported in ≥ 2 studies. RESULTS: Among 75 studies evaluating AIS surgery using pedicle screw fixation systems, 46 described rod materials and/or diameters. Two studies directly comparing titanium (Ti) and cobalt-chromium (CoCr) rods found that CoCr rods provided significantly better postoperative kyphosis angle correction vs. Ti rods during a shorter follow-up (0-3 months, MD = - 2.98°, 95% CI - 5.79 to - 0.17°, p = 0.04), and longer follow-up (≥ 24 months, MD = - 3.99°, 95% CI - 6.98 to - 1.00, p = 0.009). Surgical infection varied from 2% (95% CI 1.0-3.0%) for 5.5 mm rods to 4% (95% CI 2.0-7.0%) for 6 mm rods. Reoperation rates were lower with 5.5 mm rods 1% (95% CI 0.0-3.0%) vs. 6 mm rods [6% (95% CI 2.0-9.0%); p = 0.04]. Differences in coronal angle, lumbar lordosis, proximal junctional kyphosis, revisions, and infections did not differ significantly (p > 0.05) among rods of different materials or diameters. CONCLUSION: For AIS, CoCr rods provided better correction of thoracic kyphosis compared to Ti rods. Patients with 5.5 mm rods had fewer reoperations vs. 6.0 and 6.35 mm diameter rods. LEVEL OF EVIDENCE: III.

Early revision events among patients with a three dimensional (3D) printed cellular titanium or PEEK (polyetheretherketone) spinal cage for single-level lumbar spinal fusion.

INTRODUCTION: Three-dimensional (3D) printed spinal cages are a new design of intervertebral body fusion devices. Clinical data on these devices are limited. The objective of this study was to describe six-month events for a new and older cage design. METHODS: A retrospective, descriptive cohort study of patients that received a 3D-printed-titanium or PEEK (polyetheretherketone) cage with single-level lumbar fusion was performed using a United States hospital-based database. Outcomes evaluated were device-related revision and non-device related reoperation events 6 months after lumbar fusion. The 3D-printed-titanium and PEEK groups were propensity-score matched. Both unmatched and matched groups were descriptively analyzed. There were 93 and 2,082 patients with a 3D-printed-titanium and PEEK cage that met study criteria. The sample size was 93 patients per group after matching. RESULTS: There were no occurrences of revisions in the 3D-printed-titanium and eleven occurrences in the PEEK group before matching; PEEK had no occurrences of revision after matching. Ten total reoperation events were identified. DISCUSSION: Our findings suggest occurrence of 6-month revision or reoperation is similar or lower for both cages than reported in published literature. The low occurrence of early events for 3D-printed-titianium cages is promising. Further, real-world studies on 3D-printed cages are warranted.

Evaluation of Cost, Payments, Healthcare Utilization, and Perioperative and Post-Operative Outcomes of Patients Treated with Posterior Lumbar Spinal Surgery Using Open versus Minimally Invasive Surgical Approaches.

PURPOSE: Minimally invasive surgery (MIS) of the spine has been associated with favorable outcomes compared to open surgery. This study evaluated matched cohorts treated with MIS versus open posterior lumbar fusion for costs, payments, healthcare utilization and outcomes. PATIENTS AND METHODS: This study used the Premier Healthcare and IBM® MarketScan® Commercial and Medicare Databases. Patients with posterior lumbar fusion from 2015 to 2018 were identified and categorized as "Open" or "MIS". Cohorts were matched on patient and provider characteristics. Perioperative complications, hospital costs, healthcare utilization and post-operative outcomes and payments to providers were analyzed. Statistical significance was evaluated using T-tests and chi-square tests. RESULTS: After matching, 2,388 Open and 796 MIS from PHD, and 415 Open and 83 MIS from MarketScan were included. Statistically significant differences between MIS versus Open were found for index hospital costs, $29,181 (SD: $14,363) versus $27,616 (SD: $13,822), p=0.01; length of stay, 2.94 (SD: 2.10) versus 3.15 (SD: 2.03) days, p=0.01; perioperative urinary tract infection, 1.01% and 2.09% (p=0.05); and 30-day risk of hematoma/hemorrhage, 19.28% versus 8.43%, p=0.02. There were observed, but statistically non-significant differences in additional perioperative or post-operative complications, home discharge, 90-day all-cause and spine-related readmission, and 90-day post-operative payments. CONCLUSION: Compared to Open, patients that underwent MIS had statistically significant lower length of stay, lower perioperative UTI, greater hospital costs, and higher 30-day risk of hematoma/hemorrhage. The differences observed in post-operative complications and payments and readmissions warrant further investigation in larger matched cohorts.

Comprehensive Hip Fracture Care Program: Successive Implementation in 3 Hospitals.

INTRODUCTION: Hip fractures are common and costly in the elderly population, often contributing to loss of function and independence. Prompt, coordinated surgical care may improve clinical and economic outcomes for this population. MATERIALS AND METHODS: We created an interdisciplinary care program focused on minimizing time spent immobilized awaiting surgery and streamlining the care pathway for hip fracture. Patients older than 65 years with any hip fracture type including hip fracture repair Diagnosis-Related Group codes (MS-DRG 480, 481, or 482) and MS-DRG 469 and 470 with a hip fracture diagnosis were included in the study. The Hip Fracture Care program (HFCP) was implemented on a staggered basis in 3 hospitals in the HonorHealth system. Time to surgery, length of stay, and discharge location (home/skilled nursing facility) were compared pre- and post-intervention, utilizing an interrupted time series analysis to account for background trends. RESULTS: More than 2000 patients across the 3 facilities received HFCP care; demographics were similar for the 826 patients serving as the pre-implementation comparison group. Mean (standard deviation [SD]) length of stay decreased from 5.6 (4.0) to 4.7 (2.9) days (mean difference 0.9 days; P < .05). Mean (SD) time from admission to the operating room decreased from 30.8 (21.1) to 25.6 (20.5) hours (mean difference 5.2 hours; P < .05). There was no change in the proportion of patients discharged to home versus skilled nursing facility. DISCUSSION: Optimal care of this vulnerable population can significantly reduce the time to surgery and length of stay. CONCLUSIONS: Length of stay was reduced by nearly 1 day with implementation of a multifactorial program for hip fracture care.

Implementing a perioperative efficiency initiative for orthopedic surgery instrumentation at an academic center: A comparative before-and-after study.

Optimizing surgical instrumentation may contribute to value-based care, particularly in commonly performed procedures. We report our experience in implementing a perioperative efficiency program in 2 types of orthopedic surgery (primary total-knee arthroplasty, TKA, and total-hip arthroplasty, THA).A comparative before-and-after study with 2 participating surgeons, each performing both THA and TKA, was conducted. Our objective was to evaluate the effect of surgical tray optimization on operating and processing time, cost, and waste associated with preparation, delivery, and staging of sterile surgical instruments. The study was designed as a prospective quality improvement initiative with pre- and postimplementation operational measures and a provider satisfaction survey.A total of 96 procedures (38 preimplementation and 58 postimplementation) were assessed using time-stamped performance endpoints. The number and weight of trays and instruments processed were reduced substantially after the optimization intervention, particularly for TKA. Setup time was reduced by 23% (6 minutes, P = .01) for TKA procedures but did not differ for THA. The number of survey respondents was small, but satisfaction was high overall among personnel involved in implementation.Optimizing instrumentation trays for orthopedic procedures yielded reduction in processing time and cost. Future research should evaluate patient outcomes and incremental/additive impact on institutional quality measures.

The role of the physician in transforming the culture of healthcare.

Purpose The healthcare system in the USA is undergoing unprecedented change and its share of unintended consequences. This paper explores the leadership role of the physician in transforming the present culture of healthcare to restore, refine and preserve its traditional care components. Design/methodology/approach The literature on change, organizational culture and leadership is leveraged to describe the structural interdependencies and dynamic complexity of the present healthcare system and to suggest how physicians can strengthen the care components of the healthcare culture. Findings When an organization's culture does not support internal integration and external adaptation, it is the responsibility of leadership to transform it. Leaders can influence culture to strengthen the care components of the healthcare system. The centrality of professionalism in the delivery of patient services places a moral, societal and ethical responsibility on physicians to lead a revitalization of the care culture. Practical implications This paper focuses on cultural issues in healthcare and provides options and guidance for physicians as they attempt to lead and manage the context in which services are delivered. Originality/value The Competing Values Framework, the major interdependent domains and five principal mechanisms for leaders to embed and fine tune culture serve as the main tenets for describing the ongoing changes in healthcare and defining the role of the physician as leaders and advocates for the Patient Care Culture.

Managing in the context of healthcare's escalating technology and evolving culture.

PURPOSE: As healthcare has become more scientifically based and far more sophisticated in terms of technology, it has become more fragmented in terms of care-giving, and less personal. The purpose of this paper is to discuss the challenging task of leading and managing in the gap between the existing and emerging cultures of healthcare. DESIGN/METHODOLOGY/APPROACH: This paper considers the literature on culture, how it exists at many levels and in multiple forms, and the impacts it has on the US healthcare system. Further, the paper explores foundations of the current healthcare culture and attempts to forecast features of the emerging culture, incorporating examples of advances in scientific knowledge and technology. FINDINGS: System change will continue to be problematic until leaders and change agents find ways to operate effectively in the gap between the existing cultural tenets and those emerging as the result of scientific and technological advancements. ORIGINALITY/VALUE: Punctuated equilibrium theory serves as a main tenet for describing how changes will continue to push the USA towards a cultural tipping point. This paper contends that leaders and managers can succeed only by understanding and respecting both cultures and calls for improved theory development and research to help find creative ways to advance the new culture without trampling the old.
