ABSTRACT

Background: Although many studies worldwide have reported on violence against health care workers, there is a lack of homogeneous data for understanding the current state of the issue. Conducting a global survey required a robust team organisation structure, unique dissemination strategies, and continual networking to maintain and propagate the pool of survey collaborators and responders. Here we aimed to describe the strategies that helped us carry out a global survey-based study, the lessons learned, and provide a practical roadmap for future large-scale cross-sectional studies. Methods: We conducted this cross-sectional survey-based study from 6 June to 9 August 2022, basing it on the 'Hub and Spoke' model, with a single core team and subgroups in different regions managed by country leads. The key steps included team organisation, strategy formulation for survey dissemination and data collection, social media launch, and conducting a post-survey analysis amongst the collaborators. The core team convened weekly via video conference to discuss the modus operandi. The language barrier was managed through audio translation or by shifting to 'an interviewer-administered' questionnaire. Results: The core team included 11 members from seven countries, followed by 28 country leads from 110 countries. We also gathered 80 regional collaborators who provided feedback and spread the message. The Violence Study of Healthcare Workers and Systems (ViSHWaS) returned 5500 responses globally. Guiding principles garnered through this collaborative project include focusing on effective team organisation, ensuring external validation of survey tool, personalised communication, global networking, timely communication for maintaining momentum, and addressing regional limitations. The post-survey analysis showed that WhatsApp messaging was the most common modality used for survey dissemination, followed by in-person meetings and text messaging. We noted that the successful techniques were direct communication with respondents, regular progress updates, responsiveness to regional and country lead needs, and timely troubleshooting. The most common barriers for the respondents were limitations in language proficiency, technical fallouts, lack of compliance with, and difficulty understanding the questionnaire. Conclusions: In this global survey-based study of more than 5500 responses from over 110 countries, we noted valuable lessons in team management, survey dissemination, and addressing barriers to collaborative research.

ABSTRACT

Background: Heart failure (HF) is a major cause of recurrent hospitalization and death worldwide. Sodium-glucose cotransporter-2 inhibitors including dapagliflozin are anti-diabetic drugs with promising cardiovascular (CV) effects. We performed systematic review and meta-analysis of randomized controlled trials investigating the effects of dapagliflozin in heart failure patients. Methods: We searched PubMed, Scopus and ScienceDirect databases. A total of 1,567 studies from January 2017 to September 10, 2022, were screened. After applying exclusion criteria, 22 studies were retrieved for full-text screening, and nine of them were eligible for this meta-analysis. Effect estimates for dichotomous variables were expressed as risk ratio (RR) and 95% CI. The primary outcomes were the incidence of all-cause mortality, hospitalization due to HF, and CV death. This review was registered on PROSPERO with ID CRD42022347793. Results: A total of 14,032 patients were included. The overall risk ratio of all-cause mortality favored the dapagliflozin group over the placebo/standard therapy group (RR = 0.89, 95% CI: 0.82-0.97, P = 0.006) and the pooled studies were not heterogenous (I2 = 0%). Additionally, dapagliflozin significantly reduced the hospitalization due to heart failure (RR = 0.76, 95% CI: 0.70-0.84, P > 0.00001, I2 = 0%), cardiovascular death (RR = 0.87, 95% CI: 0.78-0.97, P = 0.01, I2 = 0%) and their composite outcomes. Conclusion: Dapagliflozin reduces the risk of all-cause mortality, heart failure hospitalizations and cardiovascular death in a wide range of heart failure patients.
