Effect of the Age-Adjusted Charlson Comorbidity Index on All-Cause Mortality and Readmission in Older Surgical Patients: A National Multicenter, Prospective Cohort Study.

Background: Identifying a high-risk group of older people before surgical procedures is very important. The study aimed to explore the association between the age-adjusted Charlson comorbidity index (ACCI) and all-cause mortality and readmission among older Chinese surgical patients (age ≥65 years). Methods: A large-scale cohort study was performed in 25 general public hospitals from six different geographic regions of China. Trained registered nurses gathered data on clinical and sociodemographic characteristics. All-cause mortality was recorded when patients died during hospitalization or during the 90-day follow-up period. Readmission was also tracked from hospital discharge to the 90-day follow-up. The ACCI, in assessing comorbidities, was categorized into two groups (≥5 vs. <5). A multiple regression model was used to examine the association between the ACCI and all-cause mortality and readmission. Results: There were 3,911 older surgical patients (mean = 72.46, SD = 6.22) in our study, with 1,934 (49.45%) males. The average ACCI score was 4.77 (SD = 1.99), and all-cause mortality was 2.51% (high ACCI = 5.06% vs. low ACCI = 0.66%, P < 0.001). After controlling for all potential confounders, the ACCI score was an independent risk factor for 90-day hospital readmission (OR = 1.18, 95% CI: 1.14, 1.23) and 90-day all-cause mortality (OR = 1.26, 95% CI: 1.16-1.36). Furthermore, older surgical patients with a high ACCI (≥5) had an increased risk of all-cause mortality (OR = 6.13, 95% CI: 3.17, 11.85) and readmission (OR = 2.13, 95% CI: 1.78, 2.56) compared to those with a low ACCI (<5). The discrimination performance of the ACCI was moderate for mortality (AUC:0.758, 95% CI: 0.715-0.80; specificity = 0.591, sensitivity = 0.846) but poor for readmission (AUC: 0.627, 95% CI: 0.605-0.648; specificity = 0.620; sensitivity = 0.590). Conclusions: The ACCI is an independent risk factor for all-cause mortality and hospital readmission among older Chinese surgical patients and could be a potential risk assessment tool to stratify high-risk older patients for surgical procedures.

Chinese orthopaedic nurses' knowledge, attitude and venous thromboembolic prophylactic practices: A multicentric cross-sectional survey.

BACKGROUND: Venous thromboembolism is a severe preventable complication among orthopaedic surgical patients. Integrating therapeutic guidelines into clinical practice can help improve patient safety and reduce the burden of this pathology. Improving the quality of patient care is important for bridging the gap between the prophylaxis for venous thromboembolism and therapeutic guidelines. OBJECTIVES: This study aimed at evaluating the knowledge, attitude, and venous thromboembolism and prophylaxis practices of Chinese orthopaedic nurses to guide quality care improvements. METHODS: The data used in this study are secondary data obtained from a multicentric survey. An anonymous questionnaire was used to measure the attitude and knowledge of venous thromboembolic prophylaxis among orthopaedic nurses. VTE prophylactic practices were extracted from medical records within the electronic case report form immediately after the nurses' investigations. The STROBE statement for observational studies was applied. RESULTS: Results indicated that although 94.0% of the responding nurses had attended training courses in their wards, a majority of them (68.9%) achieved a median knowledge score of 7 points or below (range 0-9). Knowledge regarding the proper use of prophylaxis, identification of risk factors, signs and symptoms for pulmonary embolism was limited. Self-reported attitudes underestimate the relationships between venous thromboembolism and low-quality nursing care. Pharmacological prophylaxis was highly used (90.9%), while the utilisation of mechanical prophylaxis and its proper use was relatively low. CONCLUSIONS: Chinese orthopaedic nurses demonstrated enthusiasm for venous thromboembolism and prophylaxis. Their knowledge needs to be improved, including the proper use of prophylaxis, identification of risk factors, signs and symptoms. Mechanical prophylaxis practice for VTE prevention after THA and TKA surgical procedures is not optimistic. Further studies should analyse the causes from multiple perspectives, including the availability of resources, the knowledge and attitude of doctors, nurses and patients. RELEVANCE TO CLINICAL PRACTICE: The findings from this study can be used to develop and implement interventions for venous thromboembolism after orthopaedic surgery.

Quality appraisal of clinical guidelines for venous thromboembolism prophylaxis in patients undergoing hip and knee arthroplasty: a systematic review.

INTRODUCTION: Venous thromboembolism (VTE) occurs in up to 40%-80% of patients after hip and knee arthroplasty. Clinical decision-making aided by guidelines is the most effective strategy to reduce the burden of VTE. However, the quality of guidelines is dependent on the strength of their evidence base. The objective of this article is to critically evaluate the quality of VTE prevention guidelines and the strength of their recommendations in VTE prophylaxis in patients undergoing hip and knee arthroplasty. METHODS: Relevant literature up to 16 March 2020 was systematically searched. We searched databases such as Web of Science, PubMed, EMBASE, Cumulative Index of Nursing and Allied Health Literature, China National Knowledge Infrastructure and WanFang and nine guidelines repositories. The identified guidelines were appraised by two reviewers using the Appraisal of Guidelines for Research and Evaluation II and appraised the strength of their recommendations independently. Following quality assessment, a predesigned data collection form was used to extract the characteristics of the included guideline. RESULTS: We finally included 15 guidelines. Ten of the included guidelines were rated as 'recommended' or 'recommended with modifications'. The standardised scores were relatively high in the domains of Clarity of Presentation, and Scope and Purpose. The lowest average standardised scores were observed in the domains of Applicability and Stakeholder Involvement. In reference to the domains of Rigour of Development and Editorial Independence, the standardised scores varied greatly between the guidelines. The agreement between the two appraisers is almost perfect (intraclass correlation coefficients higher than 0.80). A considerable proportion of the recommendations is based on low-quality or very-low-quality evidence or is even based on working group expert opinion. CONCLUSIONS: In summary, the majority of the recommendations are based on low-quality evidence, and further confirmation is needed. Furthermore, guideline developers should pay more attention to methodological quality, especially in the Stakeholder Involvement domain and the Applicability domain.

Association of insomnia disorder with sociodemographic factors and poor mental health in COVID-19 inpatients in China.

PURPOSE: To examine insomnia disorder and its association with sociodemographic factors and poor mental health in 2019 novel coronavirus (COVID-19) inpatients in Wuhan, China. DESIGN: and Methods: A total of 484 COVID-19 inpatients in Wuhan Tongji Hospital were selected and interviewed with standardized assessment tools. Insomnia disorder was measured by the Chinese version of the Insomnia Severity Index (ISI-7), a total score of 8 or more was accepted as the threshold for diagnosing insomnia disorder. RESULTS: The prevalence of insomnia disorder in the whole sample was 42.8%. Binary logistic regression analysis revealed that female gender, younger age, and higher fatigue and anxiety severity were more likely to experience insomnia disorder. CONCLUSION: Given the high rate of insomnia disorder status among COVID-19 inpatients in Wuhan, China, and its negative effects, follow-up assessments and appropriate psychological interventions for insomnia disorder are needed in this population.

Prevalence of depression and its association with quality of life in clinically stable patients with COVID-19.

INTRODUCTION: High risk of mental health problems is associated with Coronavirus Disease 2019 (COVID-19). This study explored the prevalence of depressive symptoms (depression hereafter) and its relationship with quality of life (QOL) in clinically stable patients with COVID-19. METHODS: This was an online survey conducted in COVID-19 patients across five designated isolation hospitals for COVID-19 in Hubei province, China. Depression and QOL were assessed with standardized instruments. RESULTS: A total of 770 participants were included. The prevalence of depression was 43.1% (95%CI: 39.6%-46.6%). Binary logistic regression analysis found that having a family member infected with COVID-19 (OR=1.51, P = 0.01), suffering from severe COVID-19 infection (OR=1.67, P = 0.03), male gender (OR=0.53, P<0.01), and frequent social media use to obtain COVID-19 related information (OR=0.65, P<0.01) were independently associated with depression. Patients with depression had lower QOL than those without. CONCLUSION: Depression is highly prevalent in clinically stable patients with COVID-19. Regular screening and appropriate treatment of depression are urgently warranted for this population.

[Relationship between Depression and Quality of Life in Patients with Severe Obesity].

Objective To investigate the depression status and quality of life (QoL) of patients with severe obesity who have undergone bariatric surgery and to evaluate their potential correlation.Methods A total of 50 patients with severe obesity who had undergone elective bariatric surgery in the general surgical ward of Peking Union Medical College from January 2013 to December 2017 were enrolled in this study. The general data were collected. The patient's depression status and QoL were assessed by the Zung's Depression Self-Assessment Scale and the SF-36 Quality of Life Scale,respectively.Results The depression score was (44.85±9.07) scores in these 50 patients,including 38 patients (76%) without depression and 12 (24%) with mild depression. The scores of the mental-emotional,physical,psychomotor,and psychological barrier dimensions of patients with severe obesity were (3.70±1.25),(18.65±4.10),(4.25±1.35),and (18.75±5.46)scores,respectively. The physiological function score of patients with mild depression was (95.83±10.21)scores,which was significantly higher than those without depression (68.42±38.95) scores(F=6.209,P=0.011). The vitality and mental health scores were (46.67±14.72) and (57.33±14.68) scores in patients with mild depression,which were significantly lower than those [(65.79±21.94) (F=4.867,P=0.030) and (75.16±17.21) scores (F=0.212,P=0.032)] in patients without depression. Correlation analysis showed that the mental-emotional score was positively correlated with physical score in patients with severe obesity (r=0.503,P=0.015),whereas the depression score was negatively correlated with the general health status (r=-0.430,P=0.032),vitality (r=-0.594,P=0.002),social functioning (r=-0.455,P=0.022),mental health (r=-0.562,P=0.003),and QoL score (r=-0.439,P=0.028).Conclusions The QoL is remarkably affected by depression in patients with severe obesity before surgery. Assessment of the mental status of patients with severe obesity may help to identify this problem and thus improve the QoL.

Nurses' objective knowledge regarding venous thromboembolism prophylaxis: A national survey study.

Venous thromboembolism (VTE) is a common vascular disorder with high mortality and morbidity. Clinical nurses are a pivotal group that can serve as first-line health care providers. Lack of knowledge about VTE is an important barrier to effective nursing performance. This study aimed to determine nurses' knowledge of VTE prophylaxis through a nationwide survey across China, to understand gaps between current knowledge, and guidelines, and to help improve clinical nursing.The survey included 5 topics with 68 items on VTE, including basic knowledge, risk assessment, basic prophylaxis, physical prophylaxis, and pharmacological prophylaxis.The survey was distributed to 106 AAA-grade hospitals throughout China; 5218 valid questionnaires were submitted for analysis. There were 5097 women and 121 men respondents, with average age 30.29 ±â€Š8.60 years. The average rate of correct responses regarding VTE knowledge was 59.90 ±â€Š15.63%; 77.81% of subjects answered more than half of the survey items correctly. Better knowledge about thromboprophylaxis was observed among nurses who were more highly educated, more experienced, had received continuing education, intensive care unit (ICU), and lead nurses. Correct response rates were 68.39 ±â€Š17.03%, 60.35 ±â€Š21.01%, 75.51 ±â€Š22.85%, 41.72 ±â€Š17.47%, and 46.01 ±â€Š21.22% for basic knowledge, risk assessment, basic prophylaxis, physical prophylaxis, and pharmacological prophylaxis, respectively.Respondents showed satisfactory results regarding basic prophylaxis, basic knowledge, and risk assessment for VTE; respondents had poorer knowledge regarding physical and pharmacological prophylaxis. Better mastery of knowledge about thromboprophylaxis was observed among nurses who were more highly educated, more experienced, had received continuous education, ICU, and lead nurses.This study suggested that nurse trainers should develop comprehensive educational programs that focus on low correct rate aspects. Higher-level continuous education could improve nurses' knowledge of thromboprophylaxis.
