Avoidable mortality (AM) is an important indicator of health system performance. It is also an effective tool for evaluating the effectiveness of health measures and allocation of health resources. The concept development, analytical methods, and research contents of avoidable mortality are introduced in this study. This study investigated the applicability of avoidable mortality analysis in determining priority health-service intervention areas, determining priority health-service intervention populations and evaluating the quality of those services. This paper also discussed the significance and limitations of avoidable mortality analysis. The investigation provided references for further research and application of avoidable mortality analysis.
ObjectivesTo systematically review the prognostic value of plasma soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) level in predicting 28-day mortality in sepsis.MethodsPubMed, The Cochrane Library, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect studies about the prognostic value of plasma sTREM-1 in early 28-day mortality in sepsis from inception to April 16th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 14.0 software.ResultsA total of 13 studies involving 1 115 patients were included. The results of meta-analysis showed that the sensitivity and specificity were 79% and 77%, respectively. The positive likelihood ratio and the negative likelihood ratio were 3.4 and 0.28, respectively. The diagnostic ratio was 12. The overall area under the summary receiver operator characteristic (SROC) curve was 0.80.ConclusionsCurrent evidence shows that plasma sTREM-1, as a single index, may play a prognostic role in the early 28-day mortality of sepsis in patients. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
In 2022, the National Cancer Center (NCC) of China reported the nationwide statistics of 2016 using population-based cancer registry data from all available cancer registries in China, which was mainly about the cancer incidence and mortality. Cancer remains a major health problem currently in our country and requires long term cooperation to deal with. This article provided a key point interpretation and analysis of cancer prevalence data in China, and provided an analysis of several main risk factors for cancer, which was conducive to the development of cancer prevention and control programs in different regions.
ObjectiveTo identify the risk factors for hospital mortality in patients with acute myocardial infarction (AMI) after emergency coronary artery bypass grafting (CABG).MethodsWe retrospectively analyzed the clinical data of 145 AMI patients undergoing emergency CABG surgery in Qingdao Municipal Hospital from 2009 to 2019. There were 108 (74.5%) males and 37 (25.5%) females with a mean age of 67.7±11.5 years. According to whether there was in-hospital death after surgery, the patients were divided into a survival group (132 patients) and a death group (13 patients). Preoperative and operative data were analyzed by univariate analysis, followed by multivariate logistic regression analysis, to identify the risk factors for hospital mortality.ResultsOver all, 13 patients died in the hospital after operation, with a mortality rate of 9.0%. In univariate analysis, significant risk factors for hospital mortality were age≥70 years, recent myocardial infarction, left ventricular ejection fraction (LVEF)<30%, left main stenosis/dissection, operation time and simultaneous surgeries (P<0.05). Multivariate logistic regression analysis showed that LVEF<30% (OR=2.235, 95%CI 1.024-9.411, P=0.014), recent myocardial infarction (OR=4.027, 95%CI 1.934-14.268, P=0.032), operation time (OR=1.039, 95%CI 1.014-1.064, P=0.002) were independent risk factors for hospital mortality after emergency CABG.ConclusionEmergency CABG in patients with AMI has good benefits, but patients with LVEF<30% and recent myocardial infarction have high in-hospital mortality, so the operation time should be shortened as much as possible.
ObjectiveTo evaluate the effectiveness and safety of proximal aortic repair (PAR) versus total arch replacement (TAR) for treatment of acute type A aortic dissection (ATAAD). Methods An electronic search was conducted for clinical controlled studies on PAR versus TAR for patients with ATAAD published in Medline via PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang Database and CNKI since their inception up to April 30, 2022. The quality of each study included was assessed by 2 evaluators and the necessary data were extracted. STATA 16 software was used to perform statistical analysis of the available data. ResultsA total of 28 cohort studies involving 7 923 patients with ATAAD were included in this meta-analysis, of whom 5 710 patients received PAR and 2 213 patients underwent TAR, and 96.43% of the studies (27/28) were rated as high quality. The meta-analysis results showed that: (1) patients who underwent PAR had lower incidences of 30 d mortality [RR=0.62, 95%CI (0.50, 0.77), P＜0.001], in-hospital mortality [RR=0.64, 95%CI (0.54, 0.77), P＜0.001], and neurologic deficiency after surgery [RR=0.84, 95%CI (0.72, 0.98), P=0.032] than those who received TAR; (2) the cardiopulmonary bypass time [WMD=–52.07, 95%CI (–74.19, –29.94), P＜0.001], circulatory arrest time [WMD=–10.14, 95%CI (–15.02, –5.26), P＜0.001], and operation time [WMD=–101.68, 95%CI (–178.63, –24.73), P＜0.001] were significantly shorter in PAR than those in TAR; (3) there was no statistical difference in mortality after discharge, rate of over 5-year survival, renal failure after surgery and re-intervention, volume of red blood cells transfusion and fresh-frozen plasma transfusion, or hospital stay between two surgical procedures. Conclusion Compared with TAR, PAR has a shorter operation time and lower early and in-hospital mortality, but there is no difference in long-term outcomes or complications between the two procedures for patients with ATAAD.
Objective To explore the thromboembolic events and mortality in patients with different types of severe pneumonia, and to analyze the related high-risk factors. Methods A total of 161 severe pneumonia patients who admitted in intensive care unit from January 2018 to February 2023 were included in the study. The patients were divided into a COVID-19 group (n=88) and a community-acquired pneumonia (CAP) group (n=73) according to the type of pneumonia, and divided into a thrombosis group and a non-thrombosis group according to the occurrence of thrombosis. The patients were followed-up until discharge or in-hospital death, registering the occurrence of thrombotic events. Results During the in-hospital stay, 32.9% of CAP and 36.4% of COVID-19 patients experienced thrombotic events (P>0.05). In CAP group all the events (including 24 paitents) were venous thromboses, while in COVID-19 group 31 patients were venous and 3 were arterial thromboses (2 were cerebral infarction, and 1 with myocardial infarction). There were statistically significant difference in gender, age, venous thromboembolism score (VTE score), activated partial thromboplastin time (APTT), and procalcitonin (PCT) between the TE group and the Non-TE group. Logistic regression analysis showed that thrombotic events was associated with sex, age and APTT; gender (female: OR=2.47, 95%CI 1.13 - 5.39, P<0.05) and age (OR=1.04, 95%CI 1.01 - 1.07, P<0.05) were positively associated with thrombotic events. During the in-hospital follow-up, 44.3% of CAP patients and 42.5% of COVID-19 patients died (P>0.05). Receiver operator characteristic (ROC) curve analysis showed that APACHEⅡ score was more accurate in predicting mortality of severe pneumonia, and the area under the ROC curve (AUC) was 0.77 (95%CI 0.70 - 0.84, sensitivity 74.3%, specificity 68.1%), the AUC of the VTE score was 0.61 (95%CI 0.53 - 0.70, Sensitivity 31.4%, specificity 81.7%); the AUC of the creatinine was 0.64 (95%CI 0.56 - 0.73, sensitivity 72.9%, specificity 51.2%). While the Kappa value for kidney disease was 0.409 (P<0.05) presenting moderate consistency. Conclusions The incidence of thromboembolic events and mortality are high in patients with different types of severe pneumonia. Thrombophilia was associated with sex, age, and APTT. APACHEⅡ score, VTE score, and creatinine value were independent risk factors for predicting death from severe pneumonia.
Risk stratifications are valuable aids for stratifying patients by disease severity, driving informed clinical decisions, because they allow the selection of the most appropriate strategy of treatment based on the patient's individual characteristics. The clinical algorithms help patients and their families to get a better understanding of issues relevant to treatment strategies and subsequent risks as part of the process to obtain informed consent. The current risk stratifications of coronary artery bypass grafting included the Society of Thoracic Surgeons Score, the European System for Cardiac Operative Risk Evaluation, SinoSystem for Coronary Operative Risk Evaluation. This review focuses on the progress of risk stratifications of coronary artery bypass grafting for patients undergoing cardiac surgery.
"Global cancer statistics 2022" based on the latest GLOBCAN data from the International Agency for Research on Cancer (IARC) was recently released, providing a systematic analysis of the incidence and mortality of 36 types of cancer across 185 countries worldwide. The international burden of cancer is expected to continue to increase over the next 30 years, posing a severe public health and social challenge for many countries, including China. This article offers a key point interpretation of the "Global cancer statistics 2022", focusing on the evolution of cancer epidemiology and future development trends. The aim is to broaden the international perspective on cancer prevention and treatment, with the hope of providing reference and guidance for cancer prevention and treatment efforts in our country.
Objective A comparative study of in-hospital mortality and risk factors of ventilator-associated pneumonia (VAP) caused by carbapenem-resistant gram-negative bacteria (CRGNB) and non-carbapenem-resistant gram-negative bacteria (nCRGNB) in China was conducted to investigate whether there is a higher in-hospital mortality of VAP caused by CRGNB and its unique associated risk factors. Methods Relevant literatures published at home and abroad in PubMed, EMBASE, Cochrane library, Web of Science, CNKI and Wanfang databases were retrieved from the date of establishment to June 1, 2021, and the quality of the included literatures was evaluated using Newcastle-Ottawa scale. Meta-analysis of literatures meeting the criteria was performed using RevMan 5.3 software. Results A total of 5 literatures were included, all of which were case-control studies with a total of 574 cases, including 302 cases in the CRGNB group and 272 cases in the nCRGNB group. The results showed that the in-patient mortality of VAP caused by CRGNB infection was significantly increased compared with that of VAP caused by nCRGNB infection (OR=2.51, 95%CI 1.71 - 3.67, P<0.00001). Risk factor analysis of CRGNB infection showed that statistically significant risk factors included mechanical ventilation duration ≥7 days (OR=2.66, 95%CI 1.23 - 5.75, P=0.01), secondary intubation (OR=4.48, 95%CI 2.61 - 7.69], P<0.00001), combined with antibiotics (OR=2.83, 95%CI 1.76 - 4.54, P<0.0001), using carbapenem antibiotics (OR=2.78, 95%CI 1.76 - 4.40, P<0.0001). In addition, two studies showed that tigecycline was sensitive to CRGNB in vitro. Conclusions Compared with nCRGNB-induced VAP, CRGNB infection significantly increases the in-hospital mortality of VAP patients in China, indicating that the in-hospital mortality of CRGNB infection is related to drug resistance, and had little relationship with region and drug resistance mechanism. Among them, mechanical ventilation duration ≥7 days, secondary intubation, combined use of antibiotics and carbapenem antibiotics are risk factors for CRGNB infection in VAP patients. Tigecycline is sensitive to most CRGNB strains in China and is an important choice for the treatment of CRGNB in China.
Objective To investigate the application of delayed sternal closure (DSC) following arterial switch operation for neonates with transposition of great arteries (D-TGA). Methods We retrospectively analyzed clinical data of 172 neonates underwent arterial switch operation with transposition of great arteries (D-TGA) between June 1st 2009 and December 31st 2015. These neonates were divided into 2 groups including a DSC group (118 patients with 99 males and 19 females) and a non-DSC group (54 patients with 47 males and 7 females). The outcome of the two groups were compared. Results Preoperative mechanical ventilation(P<0.001), emergency surgery (P=0.023) and extracorporeal circulation time (P<0.001) were the risk factors for delayed sternal closure. The incidence of complications of median sternotomy incision in the DSC group was not higher than that in the non-DSC group. The mortality rate in the DSC group was markedly higher than that in the non-DSC group (P<0.001). However, DSC was not a risk factor for the death of the neonates. Conclusion Delayed sternal closure does not increase the incidence of complications of the median sternotomy incision, nor is it a risk factor for the death of the neonates. Reasonable application of delayed sternal closure is helpful for early postoperative recovery of the neonates.
