Development of composite outcomes for individual patient data (IPD) meta-analysis on the effects of diet and lifestyle in pregnancy: a Delphi surveyby Rogozinska et al
The objective of the study was to develop maternal, fetal, and neonatal composite outcomes relevant to the evaluation of diet and lifestyle interventions in pregnancy by individual patient data (IPD) meta-analysis.A two-generational Delphi survey involving members of the i–WIP collaborative network (26 members in 11 countries) was undertaken to prioritise the individual outcomes for their importance in clinical care. The final components of the composite outcomes were identified using pre-specified criteria. The study has identified the components of maternal, fetal, and neonatal composite outcomes required for the assessment of diet and lifestyle interventions in pregnancy by IPD meta-analysis.
Building on the concept of rapid learning health systems, Dr. Peek’s seminar focuses on the use of health information technology to address epidemiological and public health questions and to accelerate the translation of research findings to clinical practice.
Randomised controlled trials are the gold standard of health research evidence. Tension often exists between people wanting to use a new intervention, and the scientists who are generating evidence through a controlled evaluation study. One way that has emerged to balance this is the stepped wedge randomised controlled trial design.
Healthcare associated infections (HAI) are of important concern in patient care. This talk discusses Visual Analytics techniques which have been developed to help detect, monitor, analyse and understand trends, clusters and outbreaks of HAI.
Anders Björkman is Professor of Infectious Disease at the Karolinska Institute. In this video, Anders talks about how the efficacy of antimalarials is a major obstacle in the path towards full malaria elimination.
Professor Mike English explains how KEMRI-Wellcome are ''working with government to generate patient level data from a network of Kenyan hospitals as a platform for research'.
Internet-based systems for epidemiological studies have advantages overtraditional approaches as they can potentially recruit and monitor a wider range of individuals in a relatively inexpensive fashion. We studied the association between communication strategies used for recruitment (offline, online, face-to-face) and follow-up participation in nine Internet-based cohorts: the Influenzanet network of platforms for influenza surveillance which includes seven cohorts in seven different European countries, the Italian birth cohort Ninfea and the New Zealand birth cohortELF. Follow-up participation varied from 43% to 89% depending on the ohort.Although there were heterogeneities among studies, participants who became aware of the study through an online communication campaign compared with those through traditional offline media seemed to have a lower follow-up participation in 8 out of 9 cohorts. There were no clear differences in participation between participants enrolled face-to-face and those enrolled through other offline strategies. An Internet-based campaign for Internet-based epidemiological studies seems to be less effective than an offline one in enrolling volunteers who keepparticipating in follow-up questionnaires. This suggests that even for Internet-based epidemiological studies an offline enrollment campaign would be helpful in order to achieve a higher participation proportion and limit the cohort attrition.
