Introduction Adverse events associated with medications are under-reported in postmarketing surveillance systems. A systematic review of published data from 37 studies worldwide (including Canada) found the median under-reporting rate of adverse events to be 94% in spontaneous reporting systems. This scoping review aims to assess the utility of social media and crowd-sourced data to detect and monitor adverse events related to health products including pharmaceuticals, medical devices, biologics and natural health products. Methods and analysis Our review conduct will follow the Joanna Briggs Institute scoping review methods manual. Literature searches were conducted in MEDLINE, EMBASE and the Cochrane Library from inception to 13 May 2016. Additional sources included searches of study registries, conference abstracts, dissertations, as well as websites of international regulatory authorities (eg, Food and Drug Administration (FDA), the WHO, European Medicines Agency). Search results will be supplemented by scanning the references of relevant reviews. We will include all publication types including published articles, editorials, websites and book sections that describe use of social media and crowd-sourced data for surveillance of adverse events associated with health products. Two reviewers will perform study selection and data abstraction independently, and discrepancies will be resolved through discussion. Data analysis will involve quantitative (eg, frequencies) and qualitative (eg, content analysis) methods. Dissemination The summary of results will be sent to Health Canada, who commissioned the review, and other relevant policymakers involved with the Drug Safety and Effectiveness Network. We will compile and circulate a 1-page policy brief and host a 1-day stakeholder meeting to discuss the implications, key messages and finalise the knowledge translation strategy. Findings from this review will ultimately inform the design and development of a data analytics platform for social media and crowd-sourced data for pharmacovigilance in Canada and internationally. Registration details Our protocol was registered prospectively with the Open Science Framework (https://osf.io/kv9hu/).

Introduction Heart failure (HF) is a leading reason for hospitalisation and readmissions to hospital, particularly among individuals older than 65 years of age. The prognosis of patients with HF is grim, with high rates of mortality risk and hospital readmissions. The transition period early after hospital discharge represents a window of opportunity to positively influence patient outcomes using quality improvement (QI) strategies. However, little is known about which QI interventions exist for early events of HF after discharge, so the main objective of our study is to conduct a scoping review of the literature to determine which QI strategies are effective for reducing hospital readmissions and mortality for patients with HF who transition from the hospital back into independent living. We will also investigate which elements contribute to effective QI strategies. Methods and analysis We will search the literature in MEDLINE, EMBASE, CINAHL and the Cochrane library for randomised controlled trials and systematic reviews evaluating QI interventions aimed at improving outcomes for patients with HF transitioning from the hospital back into the community. Two reviewers will independently apply our eligibility criteria at level 1 (abstract/title) and level 2 (full-text) screening; disagreements will be resolved through consensus. We will extract data in duplicate on study characteristics, population, setting, QI intervention and outcomes. We will synthesise results descriptively and explore QI elements to determine which aspect contributes to its impact. We will also consider synthesis of our data according to several conceptual frameworks such as Wagner9s Chronic Care Model. Discussion and dissemination The findings of this scoping review will be used to determine which elements should comprise a QI intervention aimed at facilitating the transition of newly admitted patients with HF back into the community. We will disseminate our findings through publications, presentations as well as through a stakeholder meeting to generate key messages most relevant to each.
