Applying the Fair4Health Solution to Identify Multimorbidity Patterns and Their Association with Mortality through a Frequent Pattern Growth Association Algorithm
The current availability of electronic health records represents an excellent research opportunity on multimorbidity, one of the most relevant public health problems nowadays. However, it also poses a methodological challenge due to the current lack of tools to access, harmonize and reuse research datasets. In FAIR4Health, a European Horizon 2020 project, a workflow to implement the FAIR (findability, accessibility, interoperability and reusabili…
Adaptive Time-Dependent Priors and Bayesian Inference to Evaluate Sars-CoV-2 Public Health Measures Validated on 31 Countries
With the rapid spread of the SARS-CoV-2 virus since the end of 2019, public health confinement measures to contain the propagation of the pandemic have been implemented. Our method to estimate the reproduction number using Bayesian inference with time-dependent priors enhances previous approaches by considering a dynamic prior continuously updated as restrictive measures and comportments within the society evolve. In addition, to allow direct com…
Status of health information exchange: A comparison of six countries
BACKGROUND: Health information exchange (HIE) is frequently cited as an important objective of health information technology investment because of its potential to improve quality, reduce cost, and increase patient satisfaction. In this paper we examine the status and practices of HIE in six countries, drawn from a range of higher and lower income regions. METHODS: For each of the countries represented - China, England, India, Scotland, Switzerla…
Open-Ended Questions in Web Surveys
Previous research has revealed techniques to improve response quality in open-ended questions in both paper and interviewer-administered survey modes. The purpose of this paper is to test the effectiveness of similar techniques in web surveys. Using data from a series of three random sample web surveys of Washington State University undergraduates, we examine the effects of visual and verbal answer-box manipulations (i.e., altering the size of th…
The Influence of Topic Interest and Interactive Probing on Responses to Open-Ended Questions in Web Surveys
Web surveys offer new opportunities for achieving high-quality responses to open-ended questions because the interactive nature of the web allows questions to be tailored to individual respondents. This article explores how respondents' level of interest in the topic of the question can influence whether they provide a response and the quality of their answers. In addition, we examine whether an interactive follow-up probe, asked after people sub…
Does "Yes or No" on the Telephone Mean the Same as "Check-All-That-Apply" on the Web
Recent experimental research has shown that respondents to forced-choice questions endorse significantly more options than respondents to check-all questions. This research has challenged the common assumption that these two question formats can be used interchangeably but has been limited to comparisons within a single survey mode. In this paper we use data from a 2004 random sample survey of university students to compare the forced-choice and …
Helping Respondents Get It Right the First Time: The Influence of Words, Symbols, and Graphics in Web Surveys
We utilize and apply visual design theory to experimentally test ways to improve the likelihood that web respondents report date answers in a particular format desired by the researcher, thus reducing possible deleterious effects of error messages or requests for corrections. These experiments were embedded in a series of web surveys of random samples of university students. We seek to examine the sequential and cumulative effects of visually man…
The Influence of Graphical and Symbolic Language Manipulations on Responses to Self-Administered Questions
This article reports results from 14 experimental comparisons designed to test 7 hypotheses about the effects of two types of nonverbal languages (symbols and graphics) on responses to self-administered questionnaires. The experiments were included in a survey of 1,042 university students. Significant differences were observed for most comparisons, providing support for all seven hypotheses. These results support the view that respondents' answer…
