RESUMEN

BACKGROUND: In addition to the integrity of the meniscal hoop function, both the anterior and posterior meniscus roots as well as the meniscotibial and meniscofemoral ligaments are crucial in restraining meniscal extrusion. However, the interaction and load sharing between the roots and these peripheral attachments (PAs) are not known. PURPOSES: To investigate the influence of an insufficiency of the PAs on the forces acting on a posterior medial meniscus root repair (PMMRR) in both neutral and varus alignment and to explore whether meniscal centralization reduces these forces. STUDY DESIGN: Controlled laboratory study. METHODS: In 8 fresh-frozen human cadaveric knees, an arthroscopic transosseous root repair (step 1) was performed after sectioning the posterior root of the medial meniscus. The pull-out suture was connected to a load cell to allow measurement of the forces acting on the root repair. A medial closing-wedge distal femoral osteotomy was performed to change the mechanical axis from neutral to 5° of varus alignment. The meniscus was completely released from its PAs (step 2), followed by transosseous arthroscopic centralization (step 3). Each step was tested in both neutral and varus alignment. The specimens were subjected to nondestructive dynamic varus loading under axial compression of 300 N in 0°, 15°, 30°, 45°, and 60° flexion. The changes in force acting on the PMMRR were statistically analyzed using a mixed linear model. RESULTS: Axial loading in neutral alignment led to an increase of the force of root repair of 3.1 ± 3.1 N (in 0° flexion) to 6.3 ± 4.4 N (in 60° flexion). In varus alignment, forces increased significantly from 30° (3.5 N; 95% CI, 1.1-5.8 N; P = .01) to 60° (7.1 N; 95% CI, 2.7-11.5 N; P = .007) flexion, in comparison with neutral alignment. Cutting of the PAs in neutral alignment led to a significant increase of root repair forces in all flexion angles, from 7.0 N (95% CI, 1.0-13.0 N; P = .02) to 9.1 N (95% CI, 4.1-14.1 N; P = .003), in comparison with the intact state. Varus alignment significantly increased the forces in the cut states from 4.8 N (95% CI, 1.0-8.5 N; P = .02) to 11.1 N (95% CI, 4.2-18.0 N; P = .006) from 30° to 60° flexion, in comparison with the neutral alignment. Arthroscopic centralization led to restoration of the native forces in both neutral and varus alignment, with no significant differences between the centralized and intact states. CONCLUSION: An insufficiency of the PAs of the medial meniscus, as well as varus alignment, led to increased forces acting on a PMMRR. These forces were reduced via an arthroscopic meniscal centralization. CLINICAL RELEVANCE: Performing arthroscopic meniscal centralization concomitantly with PMMRR may reduce failure of the repair by reducing the load of the root.

RESUMEN

In order to minimize the disparity between visible and infrared modalities and enhance pedestrian feature representation, a cross-modality person re-identification method is proposed, which integrates modality generation and feature enhancement. Specifically, a lightweight network is used for dimension reduction and augmentation of visible images, and intermediate modalities are generated to bridge the gap between visible images and infrared images. The Convolutional Block Attention Module is embedded into the ResNet50 backbone network to selectively emphasize key features sequentially from both channel and spatial dimensions. Additionally, the Gradient Centralization algorithm is introduced into the Stochastic Gradient Descent optimizer to accelerate convergence speed and improve generalization capability of the network model. Experimental results on SYSU-MM01 and RegDB datasets demonstrate that our improved network model achieves significant performance gains, with an increase in Rank-1 accuracy of 7.12% and 6.34%, as well as an improvement in mAP of 4.00% and 6.05%, respectively.

RESUMEN

Substance use-related problems continue to be a national public health crisis despite years of prevention efforts. Community anti-drug coalitions are well positioned to address substance use at local levels. Coalitions often rely on their members to connect to resources they need to address community issues and plan for sustainability over time. Such capacity building occurs through voluntary cooperation among members, making it essential to understand the role network connections play. This study sought to determine whether structural characteristics of coalitions' resource sharing networks impact members' perceptions of community improvement and coalition sustainability. Surveys at two timepoints collected data from 68 coalitions in Pennsylvania and Missouri on members' connections or ties to share information, personnel, money, or other types of collaboration. Analyses examined how coalition-level measurements of sectoral diversity, density, and resource sharing centralization, respectively, were associated with members' perceptions of community improvement, sustainability planning, and coalition sustainability. Sectoral diversity and centralization were unrelated to study outcomes. Density was also unrelated with perceived community improvement and sustainability planning. However, two facets of cooperative density were positively associated with perceived coalition sustainability: the density of ties to share information and the density of multiple types of collaborative ties. This study suggests that both information and other collaborative ties foster perceived coalition sustainability, although not community improvement.

RESUMEN

PURPOSE: To perform a systematic review and meta-analysis of the existing literature on meniscal centralisation procedures, analysing its impact on meniscal extrusion, joint biomechanics and clinical and radiological outcome measures. METHODS: The Cochrane Controlled Register of Trials, PubMed (MEDLINE) and Embase were used to perform a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Biomechanical studies on healthy animal or human cadaveric knee joints that assessed meniscal extrusion or tibiofemoral contact mechanics (contact area and pressure) following centralization for meniscal pathologies were included. For clinical studies, those that prospectively or retrospectively assessed patient-reported outcome measures (PROMs), postoperative knee motion, complications and radiological extrusion following centralization for meniscal pathologies were included. RESULTS: Fifteen studies were included in the analysis, comprising eight biomechanical, six clinical and one both. There were 92 knee specimens for biomechanical testing, of which 40 were human cadaveric and 52 porcine models. Biomechanical data revealed centralization to be commonly performed for posterior meniscal root tears and significantly reduced extrusion and contact pressure whilst improving contact area following a tear (p < 0.00001). Centralization restored extrusion to that of the native knee at all flexion angles described (0-90°, p = 0.25) and, compared to the torn state, brought tibiofemoral contact mechanics 3.2-5.0 times closer to the native state. Clinical data showed that 158 patients underwent centralization for extrusion. It improved postoperative Knee Injury and Osteoarthritis Outcome score (KOOS) (p = 0.006) and Lysholm scores (p < 0.00001) at 25.0 months, maintained extrusion reduction at 17.1 months (p < 0.00001) and preserved knee motion. CONCLUSION: Centralisation for various meniscal injuries associated with extrusion can reduce meniscal extrusion and improve joint biomechanics, along with clinical and radiological outcomes. Existing evidence is still scarce and exhibits a notable amount of methodological heterogeneity. LEVEL OF EVIDENCE: Systematic review of Level IV evidence.

RESUMEN

Rectal cancer surgery is complex and more technically challenging than colonic surgery. Over the last 30 years internationally, there has been a growing impetus for centralizing care to improve outcomes for rectal cancer. Centralizing care may potentially reduce variations of care, increase standardization and compliance with clinical practice guidelines. However, there are barriers to implementation at a professional, political, governance and resource allocation level. Centralization may increase inequalities to accessing healthcare, particularly impacting socioeconomically disadvantaged and rural populations with difficulties to commuting longer distances to "centres of excellence". Furthermore, it is unclear if centralization actually improves outcomes. Recent studies demonstrate that individual surgeon volume rather than hospital volume may be more important in achieving optimal outcomes. In this review, we examine the literature to assess the value of centralization for rectal cancer surgery.

RESUMEN

BACKGROUND: Cancer remains the second most common cause of death in Germany. Performance management and specialization concepts in medicine have the potential to positively influence the care and chances of survival of patients. OBJECTIVE: From the perspective of the University Hospital Freiburg (UKF), the legislative initiative within the framework of the Hospital Treatment Improvement Act (KHVVG) results in a number of medical strategic implications. This article explains and discusses the background, objectives and contents of the reform project "Occasional surgical oncology" and provides perspectives on strategic fields of action. MATERIAL AND METHODS: Analysis and interpretation of the draft of the Act for improvement of the treatment quality in hospitals and on the reform of the remuneration structures (Federal Government draft act). RESULTS: From the point of view of the UKF hospitals should engage in cooperative discussions with neighboring hospitals at the earliest opportunity to shape regional healthcare with the goals of mapping the local allocation of oncology patients for optimal treatment, mitigating the loss of patients at affected locations and preparing for patient growth at facilities that will continue to provide treatment in surgical oncology. DISCUSSION: The ongoing legislative process and the fact that a reliable analysis of relevant treatment areas will be possible for hospitals in the first half of 2025, presents particular challenges for hospitals and the strategic planning of activities. The gaps in the bill presented in this article should be urgently addressed to avoid undermining the project's goals and to support the hospitals remaining in the healthcare system in their preparations.

RESUMEN

Pain is a significant issue in rheumatoid arthritis (RA) and psoriatic arthritis (PSA) and can have a negative impact on patients' quality of life. Despite optimal control of inflammatory disease, residual chronic pain remains a major unmet medical need in RA. Pain in RA can be secondary to inflammation but can also generate neuroendocrine responses that initiate neurogenic inflammation and enhance cytokine release, leading to persistent hyperalgesia. In addition to well-known cytokines such as TNFα and IL-6, other cytokines and the JAK-STAT pathway play a role in pain modulation and inflammation. The development of chronic pain in RA involves processes beyond inflammation or structural damage. Residual pain is often observed in patients even after achieving remission or low disease activity, suggesting the involvement of non-inflammatory and central sensitization mechanisms. Moreover, fibromyalgia syndrome (FMS) is prevalent in RA patients and may contribute to persistent pain. Factors such as depression, sleep disturbance, and pro-inflammatory cytokines may contribute to the development of fibromyalgia in RA. It is essential to identify and diagnose concomitant FMS in RA patients to better manage their symptoms. Further research is needed to unravel the complexities of pain in RA. Finally, recent studies have shown that JAK inhibitors effectively reduce residual pain in RA patients, suggesting pain-reducing effects independent of their anti-inflammatory properties.

RESUMEN

Background: Decision-making during health crises differs from routine decision-making and is constrained by ambiguity about evolving epidemiological situations, urgency of response, lack of evidence, and fear. Recent analyses of governance and decision-making during COVID-19, focusing on leadership qualities, involvement of specific stakeholders, and effective resource management, do not adequately address a persisting gap in understanding the determinants of decision-making during health crises at the national level. Methods: We undertook a study to understand the processes and characteristics of decision-making during the COVID-19 pandemic in Singapore. We used a case study approach and collected empirical evidence about public health decision-making, using a combination of key informant interviews and focus group discussions with stakeholders from government, academia and civil society organizations. Findings: We argue that administrative centralization and political legitimacy played important roles in agile governance and decision-making during the pandemic in Singapore. We demonstrate the role of the Singapore government's centralization in creating a unified and coherent governance model for emergency response and the People's Action Party's (PAP) legitimacy in facilitating people's trust in the government. Health system resilience and financial reserves further facilitated an agile response, yet community participation and prioritization of vulnerable migrant populations were insufficient in the governance processes. Interpretation: Our analysis contributes to the theory and practice of crisis decision-making by highlighting the role of political and administrative determinants in agile crisis decision-making. Funding: This study is funded by the U.S. Centers for Disease Control and Prevention through a Cooperative Research Agreement (NU2HGH2020000037).

RESUMEN

This paper explores the effects and influence mechanisms of environmental centralization on enterprise technological progress and productivity in China. Taking the reform of vertical environmental governance (VEG) as a quasi-natural experiment, this paper compares the differences in total factor productivity (TFP) of enterprises in environmental centralization regions and environmental decentralization regions by adopting the staggered difference-in-differences (DID) method. The empirical results show that: (1) The average TFP of enterprises in the environmental centralization areas is 0.0598 higher than that in the environmental decentralization areas, and this average effect increases with the extension of the reform duration. (2) Environmental centralization strengthens government intervention in environmental issues. The improvement in the intensity of environmental regulation and the willingness of firm green innovation are the intermediate causes of the improvement in enterprise TFP. (3) VEG's effect is heterogeneous regarding regional development, industry type, and enterprise characteristics. This study has empirical implications for further refining the fiscal system to leverage the role of public finance on environmental governance and enterprise development.

RESUMEN

BACKGROUND: Surgical treatment of Hirschsprung's disease (HSCR) in Sweden was centralized to two tertiary pediatric surgery centers 1st of July 2018. Although complex surgical care in adults seems to benefit from centralization there is little evidence to support centralization of pediatric surgical care. The aim of this study was to assess centralization of HSCR in Sweden, with special consideration to preoperative management and outcomes in this group of patients. METHODS: This study retrospectively analyzed data of patients with HSCR that had undergone or were planned to undergo pull-through at our center, from 1st of July 2013 to 30th of June 2023. Patients managed from 1st of July 2013 to 30th of June 2018 were compared with patients managed from 1st of July 2018 to 30th of June 2023 regarding diagnostic procedures, preoperative treatment, complications and time to definitive surgery. RESULTS: Thirty-six patients were managed during the first five-year period compared to 57 during the second period. There was an increased number of patients referred from other Swedish regions to our center following the centralization. Time from diagnosis to pull-through increased from 33 to 55 days after centralization. There were no significant differences in pre-operative management or complications, general or related to stoma. CONCLUSIONS: Despite increasing patient volumes and longer time from diagnosis to pull through, centralization of care for HSCR does not seem to change the preoperative management and risk of complications. With access to support from the specialist center, transanal irrigations remain a safe mode of at home management until surgery, regardless of distance to index hospital. LEVEL OF EVIDENCE: Level III.

RESUMEN

Pancreatic and periampullary cancers pose significant challenges in oncological care due to their complexity and diagnostic difficulties. Global experiences underscore the crucial role of multidisciplinary collaboration and centralized care in improving patient outcomes in this context. Recognizing these challenges, Lombardy, Italy's most populous region, embarked on establishing pancreas units across its territory to enhance clinical outcomes and organizational efficiency. This initiative, driven by a multistakeholder approach involving the Lombardy Welfare Directorate, clinicians, and a patient association, emphasizes the centralization of complex care in high-volume hospitals, adopting a hub-and-spoke model and a multidisciplinary approach. This article outlines the process and criteria set forth for pancreas unit implementation, aiming to provide a structured framework for enhancing pancreatic cancer care. Central to this initiative is the establishment of structured criteria and minimal requirements, not only for surgery but also for other essential components of care, ensuring a comprehensive approach to pancreatic cancer management. The Lombardy model offers a structured framework for enhancing pancreatic cancer care, with potential applicability to other regions and countries seeking to improve their cancer care infrastructure.

RESUMEN

Application of Convolutional neural network in spectrum of Medical image analysis are providing benchmark outputs which converges the interest of many researchers to explore it in depth. Latest preprocessing technique Real ESRGAN (Enhanced super resolution generative adversarial network) and GFPGAN (Generative facial prior GAN) are proving their efficacy in providing high resolution dataset. Objective: Optimizer plays a vital role in upgrading the functioning of CNN model. Different optimizers like Gradient descent, Stochastic Gradient descent, Adagrad, Adadelta and Adam etc. are used for classification and segmentation of Medical image but they suffer from slow processing due to their large memory requirement. Stochastic Gradient descent suffers from high variance and is computationally expensive. Dead neuron problem also proves to detrimental to the performance of most of the optimizers. A new optimization technique Gradient Centralization is providing the unparalleled result in terms of generalization and execution time. Method: Our paper explores the next factor which is the employment of new optimization technique, Gradient centralization (GC) to our integrated framework (Model with advanced preprocessing technique). Result and conclusion: Integrated Framework of Real ESRGAN and GFPGAN with Gradient centralization provides an optimal solution for deep learning models in terms of Execution time and Loss factor improvement.

RESUMEN

BACKGROUND: Previous studies have demonstrated an association between transplantation rate per center and postoperative mortality after heart transplantation. In 2011, Sweden centralized heart transplants and waiting lists, reducing the number of centers from 3 to 2. We aimed to assess the active waiting time and pre- and post-transplant mortality before and after centralization. METHODS: Heart transplantations performed in Sweden between January 1, 2001 and December 31, 2020 were included. Background and donor organ supply data were collected from Scandiatransplant, the Swedish Thoracic Transplant Registry, and the Swedish Cardiac Surgery Registry. The Fine and Gray methods were applied to visualize cumulative incidence curves and conduct competing risk regressions. A Cox model was used to adjust for factors influencing time to post-transplant death. RESULTS: When comparing the two eras, the median active waiting time increased from 54 to 71 days (p = 0.015). The risk of mortality on the waiting list decreased in the later era (subhazard ratio 0.43; [95% confidence interval {CI} 0.25-0.74]; p = 0.002). The number of heart transplantation procedures (including pediatric patients) increased by 53%. There was a significant difference in organ utilization between eras (p = 0.033; chi-square test). 30-day and 1-year survival post-transplant rates for adults increased from 90.8% to 97.8% (p < 0.001) and from 87.9% to 94.6% (p < 0.001), respectively. 1-year mortality was reduced by 63% (hazard ratio 0.37; 95% CI 0.22-0.61). CONCLUSIONS: This nationwide study examined patients listed for and undergoing heart transplantation before and after the centralization of waiting lists and surgeries in Sweden. Waiting list mortality decreased, and 1-year post-transplantation survival was improved.

RESUMEN

PURPOSE OF REVIEW: With an aging population, extending healthy life expectancy is a global challenge. Maintaining healthy knee joint function is one of the essential factors to preserve the ability to walk and extend healthy life expectancy. Meniscus centralization was introduced in 2012 as a procedure for meniscus extrusion, one of the causes of knee osteoarthritis (OA). Initially, it was performed only for lateral meniscus (LM) extrusion, and favorable 2-year results were reported in 2016. Gradually, basic studies supporting the effectiveness of meniscus centralization have been reported, and it has also been performed for medial meniscus (MM) extrusion, with some positive results reported. Although the surgical procedures vary among the institutions, the basic concept is to reattach the loosened meniscotibial ligament to the edge of the tibial plateau to re-tension it. This review will discuss the history of development and the current status of meniscus centralization. RECENT FINDINGS: Current research shows that meniscus centralization is not performed in isolation but is often used as an augmentation along with the conventional repair of meniscus injuries, particularly posterior root tears. Biomechanical studies demonstrated that MM centralization with a posteromedial anchor can better restore meniscus function. CONCLUSION: Despite its relatively short publication history of just over ten years, meniscus centralization has shown potential as a treatment to curb the progression of knee OA and extend a healthy life. While more evidence is needed, this conclusion underscores the promising role for meniscus centralization, making it a topic of significant interest for knee surgeons and researchers.

RESUMEN

Due to improvements in treatment for primary rectal cancer, the incidence of LRRC has decreased. However, 6-12% of patients will still develop a local recurrence. Treatment of patients with LRRC can be challenging, because of complex and heterogeneous disease presentation and scarce - often low-grade - data steering clinical decisions. Previous consensus guidelines have provided some direction regarding diagnosis and treatment, but no comprehensive guidelines encompassing all aspects of the clinical management of patients with LRRC are available to date. The treatment of LRRC requires a multidisciplinary approach and overarching expertise in all domains. This broad expertise is often limited to specific expert centres, with dedicated multidisciplinary teams treating LRRC. A comprehensive, narrative literature review was performed and used to develop the Dutch National Guideline for management of LRRC, in an attempt to guide decision making for clinicians, regarding the complete clinical pathway from diagnosis to surgery.

RESUMEN

We experienced an atypical case of radial longitudinal deficiency that did not fit into any classifications, including Blauth. The patient had a bilateral hypoplastic thumb, in which the index and middle fingers were missing in the right hand. We performed surgeries in four stages: centralization of the right hand, opponensplasty of the right thumb, opponensplasty of the left thumb, and distraction lengthening of the right ulnar. Twenty-five years after the initial treatment, the patient was satisfied with the treatment and had no significant difficulty with activities of daily living.

RESUMEN

INTRODUCTION: The aim of this study was to assess the accuracy of a preoperative screening algorithm in identifying low-risk endometrial cancer (EC) patients to ensure optimal care. METHODS: A total of 277 patients with primary EC confirmed through biopsy underwent magnetic resonance imaging (MRI). Patients with risk factors for advanced high-risk EC, such as non-endometrioid histology, high-grade differentiation status, deep myometrial invasion, or spread beyond the uterine corpus, were systematically excluded. The remaining preoperatively screened patients with stage IA low-grade endometrioid EC (EEC) (n = 93) underwent surgery in a tertiary hospital. The accuracy of the preoperative diagnosis was evaluated by comparing the findings with the postoperative histopathological results. Disease-free survival (DFS) and overall survival (OS) were analyzed using 8-year follow-up data. RESULTS: Postoperative histopathological analysis revealed that all patients had grade 1-2 EEC localized to the corpus uteri. Only three patients had deep myometrial invasion (stage IB), but they remained disease-free after 6-9 years of follow-up. The median follow-up time for all patients was 8.7 years. The DFS was 7.6 years, and the OS was 8.6 years. Two patients with stage IA grade 1 EEC experienced relapse and, despite treatment, died of EC. No other EC-related deaths occurred. CONCLUSIONS: The screening algorithm accurately identified low-risk EC patients without compromising survival. Therefore, the algorithm appears to be feasible for selecting patients for surgery in secondary hospitals.

RESUMEN

INTRODUCTION: New Zealand has a population of only 5.5 million meaning that for many surgical procedures the country qualifies as a "low-volume center." However, the health system is well developed and required to provide complex surgical procedures that benchmark internationally against comparable countries. This investigation was undertaken to review regional variation and volumes of complex resection and palliative upper gastrointestinal (UGI) surgical procedures within New Zealand. METHODS: Data pertaining to patients undergoing complex resectional UGI procedures (esophagectomy, gastrectomy, pancreatectomy, and hepatectomies) and palliative UGI procedures (esophageal stenting, enteroenterostomy, biliary enteric anastomosis, and liver ablation) in a New Zealand hospital between January 1, 2000 and December 31, 2019 were obtained from the National Minimum Dataset. RESULTS: New Zealand is a low-volume center for UGI surgery (229 hepatectomies, 250 gastrectomies, 126 pancreatectomies, and 74 esophagectomies annually). Over 80% of patients undergoing hepatic resection/ablation, gastrectomy, esophagectomy, and pancreatectomy are treated in one of the six national cancer centers (Auckland, Waikato, Mid-Central, Capital Coast, Canterbury, or Southern). There is evidence of the decreasing frequency of these procedures in small centers with increasing frequency in large centers suggesting that some regionalization is occurring. Palliative procedures were more widely performed. Indigenous Maori were less likely to be treated in a nationally designated cancer center than non-Maori. CONCLUSIONS: The challenge for New Zealand and similarly sized countries is to develop and implement a system that optimizes the skills and pathways that come from a frequent performance of complex surgery while maintaining system resilience and ensuring equitable access for all patients.

RESUMEN

OBJECTIVE: To explore the efficacy of high tibial osteotomy (HTO) combined with medial meniscus centralization in knee osteoarthritis. METHODS: A total of 26 patients who underwent surgery from October 2018 to October 2020 were reviewed. Among them, 14 patients underwent high tibial osteotomy combined with arthroscopic meniscus centralization surgery were centralized group, including 8 males and 6 females, with an average age of (50.2±1.4) years old and follow-up time of (16.8±4.0) months. Twelve patients with high tibial osteotomy were in the control group, including 6 males and 6 females, with an average age of (50.9±1.8) years and follow-up time of (19.0±4.8) months. Operation time, the knee Lysholm score, knee 2000 IKDC score, MRI, femoral tibial angle(FTA), hip knee ankle angle (HKA), and intraoperative and postoperative complications were recorded. RESULTS: All the incisions healed without any complication. The operation time in the centralized group was longer than that in the control group[(65.0±2.1)min vs(52.0±2.1)min, P<0.05]. The medial meniscus extrusion reduction value in the centralized group was significantly reduced compared with the control group[(2.8±1.4) mm vs (1.1±2.2) mm, P<0.05]. The FTA, HKA, knee Lyshlom score, and 2000 IKDC score between two groups were no significantly (P>0.05). Postoperative knee Lyshlom score and knee 2000 IKDC score improved in both groups(P<0.05). CONCLUSION: HTO combined with centralization of medial meniscus can improve the reduction of medial meniscus and improve knee function. The medium and long-term curative effect still needs long-term follow-up of more cases.

RESUMEN

BACKGROUND: Addition of oxaliplatin-based hyperthermic intraperitoneal chemotherapy (HIPEC) to cytoreductive surgery (CRS) in the treatment of peritoneal metastases of colorectal origin (CRPM) did not show any survival benefit in the PRODIGE 7 trial (P7). This study aimed to investigate whether perioperative outcomes after CRS alone for CRPM patients is mediated by hospital volume and to determine the effect of P7 on French practice for CRPM patients treated respectively with CRS alone and CRS/HIPEC. METHODS: Data from CRPM patients treated with CRS alone between 2013 and 2020 in France were collected through a national medical database. The study used a cutoff value of the annual CRS-alone caseload affecting the 90-day postoperative mortality (POM) determined from our previous study to define low-volume (LV) HIPEC and high-volume (HV) HIPEC centers. Perioperative outcomes were compared between no-HIPEC, LV-HIPEC, and HV-HIPEC centers. The trend between years and HIPEC rates was analyzed using the Cochrane-Armitage test. RESULTS: Data from 4159 procedures were analyzed. The patients treated in no-HIPEC and LV-HIPEC centers were older compared with HV-HIPEC centers (p < 0.0001) and had a higher Elixhauser comorbidity index (p < 0.0001) and less complex surgery (p < 0.0001). Whereas the major morbidity (MM) rate did not differ between groups (p = 0.79), the 90-day POM was lower in HV-HIPEC centers than in no-HIPEC and LV-HIPEC centers (5.4% vs 15% and 13.3%; p < 0.0001), with lower failure-to-rescue (FTR) (p < 0.0001). After P7, the CRS/HIPEC rate decreased drastically in Cancer centers (p < 0.001), whereas patients treated with CRS alone are still referred to expert centers. CONCLUSIONS: Centralization of CRS alone should improve patient selection as well as FTR and POM. After P7, CRS/HIPEC decreased mostly in Cancer centers, without any impact on the number of CRS-alone cases referred to expert centers.
