Obesity and revision surgery, mortality, and patient-reported outcomes after primary knee replacement surgery in the National Joint Registry: A UK cohort study

Background One in 10 people in the United Kingdom will need a total knee replacement (TKR) during their lifetime. Access to this life-changing operation has recently been restricted based on body mass index (BMI) due to belief that high BMI may lead to poorer outcomes. We investigated the associations between BMI and revision surgery, mortality, and pain/function using what we believe to be the world’s largest joint replacement registry. Methods and findings We analysed 493,710 TKRs in the National Joint Registry (NJR) for England, Wales, Northern Ireland, and the Isle of Man from 2005 to 2016 to investigate 90-day mortality and 10-year cumulative revision. Hospital Episodes Statistics (HES) and Patient Reported Outcome Measures (PROMs) databases were linked to the NJR to investigate change in Oxford Knee Score (OKS) 6 months postoperatively. After adjustment for age, sex, American Society of Anaesthesiologists (ASA) grade, indication for operation, year of primary TKR, and fixation type, patients with high BMI were more likely to undergo revision surgery within 10 years compared to those with “normal” BMI (obese class II hazard ratio (HR) 1.21, 95% CI: 1.10, 1.32 (p < 0.001) and obese class III HR 1.13, 95% CI: 1.02, 1.26 (p = 0.026)). All BMI classes had revision estimates within the recognised 10-year benchmark of 5%. Overweight and obese class I patients had lower mortality than patients with “normal” BMI (HR 0.76, 95% CI: 0.65, 0.90 (p = 0.001) and HR 0.69, 95% CI: 0.58, 0.82 (p < 0.001)). All BMI categories saw absolute increases in OKS after 6 months (range 18–20 points). The relative improvement in OKS was lower in overweight and obese patients than those with “normal” BMI, but the difference was below the minimal detectable change (MDC; 4 points). The main limitations were missing BMI particularly in the early years of data collection and a potential selection bias effect of surgeons selecting the fitter patients with raised BMI for surgery. Conclusions Given revision estimates in all BMI groups below the recognised threshold, no evidence of increased mortality, and difference in change in OKS below the MDC, this large national registry shows no evidence of poorer outcomes in patients with high BMI. This study does not support rationing of TKR based on increased BMI.

Challenges in the Surgical Treatment of Atrioventricular Septal Defect in Children With and Without Down Syndrome in Romania-A Developing Country

Background: Atrioventricular septal defect (AVSD) is a cardiac malformation that accounts for up to 5% of total congenital heart disease, occurring with high frequency in people with Down Syndrome (DS). We aimed to establish the surgical challenges and outcome of medical care in different types of AVSD in children with DS compared to those without DS (WDS).Methods: The study included 62 children (31 with DS) with AVSD, evaluated over a 5 year period.Results: Complete AVSD was observed in 49 (79%) children (27 with DS). Six children had partial AVSD (all WDS) and seven had intermediate types of AVSD (4 with DS). Eight children had unbalanced complete AVSD (1 DS). Median age at diagnosis and age at surgical intervention in complete AVSD was not significantly different in children with DS compared to those WDS (7.5 months vs. 8.6). Median age at surgical intervention for partial and transitional AVSDs was 10.5 months for DS and 17.8 months in those without DS. A large number of patients were not operated: 13/31 with DS and 8/31 WDS.Conclusion: The complete form of AVSD was more frequent in DS group, having worse prognosis, while unbalanced AVSD was observed predominantly in the group without DS. Children with DS required special attention due to increased risk of pulmonary hypertension. Late diagnosis was an important risk factor for poor prognosis, in the setting of suboptimal access to cardiac surgery for patients in Romania. Although post-surgery mortality was low, infant mortality before surgery remains high. Increased awareness is needed in order to provide early diagnosis of AVSD and enable optimal surgical treatment.

Pediatric Cardiac Surgical Patterns of Practice and Outcomes in Japan and Europe

Objectives: The Japan Cardiovascular Surgery Database–Congenital section (JCVSD-Congenital) and the European Congenital Heart Surgeons Association (ECHSA) Congenital Heart Surgery Database (CHSD) share the same nomenclature. We aimed at comparing congenital cardiac surgical patterns of practice and outcomes in Japan and Europe using the JCVSD-Congenital and ECHSA-CHSD. Methods and Results: We examined Japanese (120 units, 63,365 operations) and European (96 units, 90,098 operations) data in JCVSD-Congenital and ECHSA-CHSD from 2011 to 2017. Patients’ age and weight, periprocedural times, mortality at hospital discharge, and postoperative length of stay were calculated for ten benchmark operations. There was a significantly higher proportion of ventricular septal defect closures and Glenn operations and a significantly lower proportion of coarctation repairs, tetralogy of Fallot repairs, atrioventricular septal defect repairs, arterial switch operations, truncus repairs, Norwood operations, and Fontan operations in JCVSD-Congenital compared to ECHSA-CHSD. Postoperative length of stay was significantly longer following all benchmark operations in JCVSD-Congenital compared to ECHSA-CHSD. Mean STAT mortality score (Society of Thoracic Surgeons European Association for Cardio-Thoracic Surgery mortality score) was significantly higher in JCVSD-Congenital (0.78) compared to ECHSA-CHSD (0.71). Mortality at hospital discharge was significantly lower in JCVSD-Congenital (4.2%) compared to ECHSA-CHSD (6.0%, P < .001). Conclusions: The distribution of the benchmark procedures and age at the time of surgery differ between Japan and Europe. Postoperative length of stay is longer, and the mean complexity is higher in Japan compared to European data. These comparisons of patterns of practice and outcomes demonstrate opportunities for continuing bidirectional transcontinental collaboration and quality improvement.

LONG-TERM RESULTS OF THERAPY OF H. PYLORI PEPTIC ULCER ASSOCIATED WITH HELICOBACTER PYLORI

Высокая распространенность, постоянный рост заболеваемости, увеличение случаев атипичных форм, числа осложнений, требующих оперативного вмешательства, смертности в связи с новой социально-экономической и экологической обстановкой, колоссальный экономический ущерб, наносимый обществу, ставят язвенную болезнь в ряд важнейших социально-медицинских проблем. В связи с этим одной из задач научной и практической гастроэнтерологии остается изучение этиологии, патогенеза, разработка и совершенствование, оптимизация и удешевление методов диагностики и лечения ЯБ, а также возможности прогнозирования динамики процесса, степени чувствительности к лечению, оценки эффективности последнего. Статья посвящена результатам исследования по ретроспективному анализу течения язвенной болезни после лечения с применением антихеликобактерных схем на основе проведения анкетированного опроса для оценки эффективности отдаленных результатов антихеликобактерной терапии. Полученные данные обрабатывали статистически с помощью программ «Microsoft Excel» 5.0 и «Statistica» 6.0 for Windows. Полученные результаты позволяют сделать выводы о том, продолжение рецидивирования язвенной болезни после применения антихеликобактерной терапии может быть связано с неполной эрадикацией хеликобактер пилори, с повторным реинфицированием, определенную роль могут играть и нарушения вегетативного баланса, как проявление дизадаптационно - регуляторных изменений The high prevalence, constant increase in morbidity, increase in cases of atypical forms, the number of complications requiring surgery, mortality due to the new socio-economic and environmental situation, and the enormous economic damage caused to society, put peptic ulcer disease among the most important socio-medical problems. In this regard, one of the tasks of scientific and practical gastroenterology is to study the etiology and pathogenesis, develop and improve, optimize and reduce the cost of methods for diagnosing and treating YB, as well as the possibility of predicting the dynamics of the process, the degree of sensitivity to treatment, and evaluating the effectiveness of THE latter. The article is devoted to the results of a study on retrospective analysis of the ulcer after treatment of H. pylori schemes through questionnaires survey to assess the effectiveness of remote results of therapy of H. pylori. The obtained data were processed statistically using the programs "Microsoft Excel" 5.0 and "Statistica" 6.0 for Windows. The results obtained allow us to conclude that the continuation of recurrence of ulcerative boseni after the use of anti-Helicobacter pylori therapy may be associated with incomplete eradication of Helicobacter pylori, with repeated reinfection, and a certain role may be played by violations of the vegetative balance, as a manifestation of dysadaptation-regulatory changes

Impact of preoperative echocardiography on surgical delays and outcomes among adults with hip fracture

Aims Echocardiography is commonly used in hip fracture patients to evaluate perioperative cardiac risk. However, echocardiography that delays surgical repair may be harmful. The objective of this study was to compare surgical wait times, mortality, length of stay (LOS), and healthcare costs for similar hip fracture patients evaluated with and without preoperative echocardiograms. Methods A population-based, matched cohort study of all hip fracture patients (aged over 45 years) in Ontario, Canada between 2009 and 2014 was conducted. The primary exposure was preoperative echocardiography (occurring between hospital admission and surgery). Mortality rates, surgical wait times, postoperative LOS, and medical costs (expressed as 2013$ CAN) up to one year postoperatively were assessed after propensity-score matching. Results A total of 2,354 of 42,230 (5.6%) eligible hip fracture patients received a preoperative echocardiogram during the study period. Echocardiography ordering practices varied among hospitals, ranging from 0% to 23.0% of hip fracture patients at different hospital sites. After successfully matching 2,298 (97.6%) patients, echocardiography was associated with significantly increased risks of mortality at 90 days (20.1% vs 16.8%; p = 0.004) and one year (32.9% vs 27.8%; p < 0.001), but not at 30 days (11.4% vs 9.8%; p = 0.084). Patients with echocardiography also had a mean increased delay from presentation to surgery (68.80 hours (SD 44.23) vs 39.69 hours (SD 27.09); p < 0.001), total LOS (19.49 days (SD 25.39) vs 15.94 days (SD 22.48); p < 0.001), and total healthcare costs at one year ($51,714.69 (SD 54,675.28) vs $41,861.47 (SD 50,854.12); p < 0.001). Conclusion Preoperative echocardiography for hip fracture patients is associated with increased postoperative mortality at 90 days and one year but not at 30 days. Preoperative echocardiography is also associated with increased surgical delay, postoperative LOS, and total healthcare costs at one year. Echocardiography should be considered an urgent test when ordered to prevent additional surgical delay. Cite this article: Bone Joint J 2021;103-B(2):271–278.

Explaining health system responses to public reporting of cardiac surgery mortality in England and the USA

Public reporting of clinical performance is increasingly used in many countries to improve quality and enhance accountability of the health system. The assumption is that greater transparency will stimulate improvements by clinicians in response to peer pressure, patient choice or competition. The international diffusion of public reporting might suggest greater similarity between health systems. Alternatively, national and local contexts (including health system imperatives, professional power and organisational culture) might continue to shape its form and impact, implying continued divergence. The paper considers public reporting in the USA and England through the lens of Scott's ‘pillars’ institutional framework. The USA was arguably the first country to adopt public reporting systematically in the late 1980s. England is a more recent adopter; it is now being widely adopted through the National Health Service (NHS). Drawing on qualitative data from California and England, this paper compares the behavioural and policy responses to public reporting by health system stakeholders at micro, meso and macro levels and through the intersection of ideas, interests, institutions and individuals through. The interplay between the regulative, normative and cultural-cognitive pillars helps explain the observed patterns of on-going divergence.
