BackgroundUnder the circumstance of global population aging, the issue on how to facilitate the quality of life (QOL) for older people brings us grand challenge. On the way to solve this problem, it is inextricable to measure QOL for older people accurately at onset. This study is aimed at evaluating the reliability and validity of the Chinese version of the World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-OLD).MethodsWe received 1005 valid WHOQOL-OLD questionnaires from 1050 respondents who were 60 and older by quota sampling method. To calculate the test-retest correlation coefficient we re-interviewed 101 participants from the community. Psychometric properties were evaluated from the aspect of feasibility, internal consistency reliability, test-retest reliability, content validity, construct validity and discriminant validity.ResultsMissing item responses took up 0.0%-2.7% in the scale. The WHOQOL-OLD showed satisfactory reliability with Cronbach’s Alpha coefficients ranging from 0.711 (Social participation) to 0.842 (Sensory ability) for each domain. The intra-class correlation coefficients (ICC) presenting test-retest reliability were all over 0.7. In Confirmatory Factor Analysis (CFA), Root Mean Square Error of Approximation (RMSEA) was 0.084 (a little more than 0.08) and comparative fit index (CFI) 0.95 (>0.90) which meant acceptable construct validity. There were higher correlation coefficients between items and their hypothesized domains than other domains (P < 0.001), indicating good content validity. The results of t-test showed good discriminant validity of the WHOQOL-OLD between the healthy group and the unhealthy group (P < 0.0083).ConclusionThe Chinese version of WHOQOL-OLD showed good feasibility, reliability and validity in this study. However, before it can be used national-widely, further research should be conducted in other areas of China.
Background Registry studies in high‐income countries have defined contemporary management of heart failure (HF), but few such data exist in the large aging population of China. We report the study design and baseline characteristics of the Heart Failure Registry of Patient Outcomes (HERO) study, undertaken to determine evidence–practice gaps in the management of HF in a broad and representative population of China. Methods and results The HERO study is a prospective, longitudinal, seasonally‐rotating, multicentre registry study of patients hospitalized with acute HF who are followed up over 12 months. Patients were recruited on the basis of primary admission clinical diagnosis of acute HF at 73 hospitals in Henan, the largest and most socio‐economically diverse province in China, from November 2017 to November 2018; follow‐up is ongoing. For each patient, data obtained through interview and medial record review by independent clinical research staff include: socio‐demographics, clinical features, diagnostic investigations, and treatment, with a subset of patients providing blood samples for future biomarker investigation. Surviving patients are scheduled to be followed up by telephone at 2 weeks, and 3, 6 and 12 months post‐admission, or until death or study withdrawal. A total of 5620 patients (mean age 72 ± 12 years; 50% female) with acute HF were recruited from 8 provincial‐, 22 municipal‐, and 43 county‐level hospitals. Patients had co‐morbid hypertensive (48%), coronary (29%), or metabolic (20%) diseases. Among 3147 patients who had echocardiography, 54%, 20% and 25% of patients had ejection fraction of ≥50%, 40–50%, and < 40%, respectively. In‐hospital or 3‐day post‐discharge mortality was 3.2% (182/5620). Death or readmission rate from the 4th day post‐discharge to first follow‐up (median 32 days) was 22.4% (977/4368). Conclusions The HERO study provides a unique opportunity to profile evidence–practice gaps across a broad spectrum of patients with acute HF in China.
Bridging the ‘know-do gap’ is an enormous challenge for global health practitioners. They must be able to understand local health dynamics within the operational and social contexts that engender them, test and adjust approaches to implementation in collaboration with communities and stakeholders, interpret data to inform policy decisions, and design adaptive and resilient health systems at scale. These skills and methods have been formalized within the nascent field of Implementation Science (IS). As graduates of the world's first PhD program dedicated explicitly to IS, we have a unique perspective on the value of IS and the training, knowledge, and skills essential to bridging the ‘know-do gap’. In this article, we describe the philosophy and curricula at the core of our program, outline the methods vital to IS in a global health context, and detail the role that we believe IS will increasingly play in global health practice. At this junction of enormous challenges and opportunities, we believe that IS offers the necessary tools for global health professionals to address complex problems in context and raises the bar of success for the global health programs of the future.
Objective To review the research on fear of childbirth, analyze and evaluate the publications by means of bibliometric analysis, and provide suggestions and scopes for future study. Data sources Web of Science, PubMed, Embase and the Cochrane Library databases. Study selection All published articles focusing on the fear of childbirth from inception to February 10, 2020. Data extraction A total of 743 articles were included for final analysis. Bibliographic data were exported from databases and then cleaned manually before using Microsoft Excel and VOSviewer to analyze and visualize the findings. Data synthesis It was found that 743 articles have been cited 31515 times (h-index: 98). The volume of publications increased by 29.3 times in the past two decades. Across the globe, Sweden was the most prolific country having 129 articles (17.4%) with six of its institutions in the top ten most prolific institutions in the world. Fifty-two (7.8%) documents were published in Midwifery journal. The most prolific author was Hildingsson, who published 35 articles (4.7%). “Cesarean section,” “experience,” and “factor” were the words that appeared most frequently in titles and abstracts of studies. “Point prevalence of psychiatric disorders during the second trimester of pregnancy: A population-based study” was the most cited article and received 525 citations. Conclusion There is an increasing interest in the research in fear of childbirth during the past two decades. This study has demonstrated that the Swedish authors have a leading role on this topic. Researchers especially in countries with high birth rates, need to promote research projects in this field as it is an important public health issue.
IntroductionInfluenza virus infection is known to increase the risk of cardiovascular events, especially in populations with pre-existing cardiovascular disease (CVD). Considering that influenza is vaccine preventable, international guidelines recommend high-risk populations with CVD receive an influenza vaccine every year. However, there are various classifications of recommendations and levels of evidence. Previous systematic reviews concluded uncertain evidence on influenza vaccine efficacy for preventing cardiovascular events in the general population or in populations with pre-existing CVD. Limited safety data of influenza vaccines were reported for populations with pre-existing CVD. Randomised controlled trials with larger sample sizes relative to previous studies are emerging, the findings of these trials are likely to be highly influential on summary efficacy estimates.Methods and analysisWe aim to perform a living systematic review and a prospective meta-analysis to evaluate the efficacy and safety of influenza vaccines compared with no vaccines or placebo for preventing mortality or CVD events in the general population and in populations with pre-existing CVD. Any types of randomised controlled trial and observational study meeting the Population, Intervention, Comparator, Outcome and Study design criteria for the research question will be selected for inclusion. The living systematic review status will be maintained for 3 years with an update for every 6 months. Mainstream medical literature databases will be independently searched by two authors with predefined strategies. Two authors will perform the risk of bias assessment with consensus. Narrative synthesis and meta-analyses will be performed to summarise the results.Ethics and disseminationFormal ethical review is not required as this study does not involve primary data collection. We will publish results of the living systematic review and prospective meta-analysis in a peer-reviewed journal. Findings will also be presented at relevant meetings.PROSPERO registration numberCRD42021222519.
