Abstract

Introduction: Patient accessible electronic health records can be used to inform and empower patients. However, their use may require complementary information seeking since they can be difficult to interpret. So far, relatively little is known of the information seeking that takes place in connection to health record use, and especially the way it varies in different age groups. A better understanding of patients’ preferences of where and how to find explanatory information provides valuable input for the development of health information provision and counselling services. Method: The analysis is based on the results of a national survey of Swedish individuals (N=1,411) who had used a national patient accessible electronic health record system (Journalen). Analysis: The data were analysed in SPSS 24.0 using Kruskal-Wallis tests for detecting group-wise differences and Jonckheere-Terpstra tests for discovering age-related trends in the data. Findings: Older patients were more likely to use a telephone and younger patients to use social contacts to ask for clarification. Generally, older adults born between 1946–1960 appear as passive information seekers. Conclusion: Age groups differ in their preferences on how to seek clarification, which underlines the importance of a better understanding of individual differences in delivering not only technically but also intellectually accessible health information. Calling by telephone could be a habit of present older generations whereas, to a degree, searching information online could be a comparable habit of current younger generations.

Abstract

To address the research gap on age-based differences in health information literacy (HIL), we investigated how younger (born 1960–) and older adults (1946–1960), and elderly citizens (–1945) differed from each other by their HIL competencies. Data were collected with an online survey of patients using the Swedish national electronic health record system. Altogether, 2,587 users responded. One-way ANOVA with post hoc tests revealed several differences between the groups: younger adults were less likely to value health information than older adults; older adults and elderly were least likely to compare information from multiple sources and had trouble in determining health information needs; older adults were most likely to have trouble understanding health terminology and the elderly to have difficulties in understanding medicinal package labels. The study shows that HIL is not necessarily improving or declining but adapting to challenges of advanced age.

Abstract

Stratification of women according to their risk of breast cancer based on polygenic risk scores (PRSs) could improve screening and prevention strategies. Our aim was to develop PRSs, optimized for prediction of estrogen receptor (ER)-specific disease, from the largest available genome-wide association dataset and to empirically validate the PRSs in prospective studies. The development dataset comprised 94,075 case subjects and 75,017 control subjects of European ancestry from 69 studies, divided into training and validation sets. Samples were genotyped using genome-wide arrays, and single-nucleotide polymorphisms (SNPs) were selected by stepwise regression or lasso penalized regression. The best performing PRSs were validated in an independent test set comprising 11,428 case subjects and 18,323 control subjects from 10 prospective studies and 190,040 women from UK Biobank (3,215 incident breast cancers). For the best PRSs (313 SNPs), the odds ratio for overall disease per 1 standard deviation in ten prospective studies was 1.61 (95%CI: 1.57–1.65) with area under receiver-operator curve (AUC) = 0.630 (95%CI: 0.628–0.651). The lifetime risk of overall breast cancer in the top centile of the PRSs was 32.6%. Compared with women in the middle quintile, those in the highest 1% of risk had 4.37- and 2.78-fold risks, and those in the lowest 1% of risk had 0.16- and 0.27-fold risks, of developing ER-positive and ER-negative disease, respectively. Goodness-of-fit tests indicated that this PRS was well calibrated and predicts disease risk accurately in the tails of the distribution. This PRS is a powerful and reliable predictor of breast cancer risk that may improve breast cancer prevention programs.
