BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for many inflammatory disorders and pain-related illnesses. Despite their widespread use, the association between NSAIDs and the incidence of atrial fibrillation (AF) remains unclear. The aim of this systematic review and meta-analysis is to investigate this association. METHODS: A systematic review was conducted in MEDLINE, EMBASE and Cochrane databases from inception through August 2019 to identify studies that evaluated the risk of AF among patients using NSAIDs. Pooled risk ratios (RRs) and 95% CI were calculated using a random-effect, generic inverse variance method. The protocol for this meta-analysis is registered with PROSPERO (International Prospective Register of Systematic Reviews; no. CRD42019141609). RESULTS: Eight observational studies (four case-control studies and four cohort studies) with a total of 14 806 420 patients were enrolled. When compared with nonNSAIDs users, the pooled RR of AF in patients with NSAIDs use was 1.29 (95% CI 1.19-1.39). Meta-analyses based on the type of study were additionally performed. Subgroup analysis by study design revealed a significant association between the use of NSAIDs and AF for both case-control studies (pooled RR 1.37; 95% CI, 1.15-1.63) and cohort studies (pooled RR 1.22; 95% CI, 1.14-1.31). Sub-analyses based on specific NSAIDs showed pooled RRs of AF in patients using ibuprofen of 1.30 (95% CI 1.22-1.39), naproxen of 1.44 (95% CI 1.18-1.76) and diclofenac of 1.37 (95% CI 1.10-1.71), respectively. Funnel plot and Egger's regression asymmetry tests were performed and showed no publication bias. CONCLUSION: NSAID use is associated with incident AF. Our study also demonstrated a consistent result among different NSAIDs.

INTRODUCTION: Achieving a standard of clinical research at the pinnacle of the evidence pyramid is historically expensive and logistically challenging. Research collaboratives have delivered high-impact prospective multicentre audits and clinical trials by using trainee networks with a range of enabling technology. This review outlines such use of technology in the UK and provides a framework of recommended technologies for future studies. METHODS: A review of the literature identified technology used in collaborative projects. Additional technologies were identified through web searches. Technologies were grouped into themes including access (networking and engagement), collaboration and event organisation. The technologies available to support each theme were studied further to outline relative benefits and limitations. FINDINGS: Thirty-three articles from trainee research collaboratives were identified. The most frequently documented technologies were social media applications, website platforms and research databases. The Supportive Technologies in Collaborative Research framework is proposed, providing a structure for using the technologies available to support multicentre collaboration. Such technologies are often overlooked in the literature by established and start-up collaborative project groups. If used correctly, they might help to overcome the physical, logistical and financial barriers of multicentre clinical trials.
