‘Dr Google’ Will See You Now! A Review of Online Consumer Information about Anticoagulant and Antithrombotic Medication for Prevention of Recurrent Stroke

A reliability and validity study of the electronic health literacy scale among stroke patients in China

BACKGROUND

Patients with stroke usually use smartphones to obtain online information to maintain their health. But their ability to identify, evaluate and apply this information is still unknown.

AIM

This study was designed to examine the reliability and validity of the electronic Health Literacy Scale among patients with stroke in China.

DESIGN

This is a cross-sectional survey.

METHODS

A demographic questionnaire, the electronic Health Literacy Scale (e-HLS) and the eHealth Literacy Scale (eHEALS) were administered to a sample of 648 patients with ischemic stroke recruited from December 2020 to March 2021 in a tertiary hospital.

RESULTS

The Cronbach'α coefficient on the e-HLS-CHI was 0.907. Kappa consistency coefficient of test-retest reliability was 0.691 (p < .05). Three factors were extracted by Exploratory Factor Analysis (EFA), accounting for 90.84% of the total variance. Confirmatory Factory Analysis (CFA) revealed that three factors of e-HLS-CHI fit well (NFI = 0.979, RFI = 0.955, IFI = 0.987, TLI = 0.972, CFI = 0.987, RMSEA = 0.070, CMIN/DF = 2.586). Good simultaneous validity was suggested by the positive correlation of 0.94 (p < .001) between the e-HLS-CHI and eHEALS. When using eHEALS as the standard, the area under the ROC curve of e-HLS-CHI was 0.896 (95% CI: 0.831-0.960, p < .001). The sensitivity and specificity were 97.8% and 70.4% respectively.

CONCLUSIONS

The e-HLS can be used to evaluate electronic health literacy of patients with stroke in China after translation and cultural adaption.

The influence of online health information on health decisions: A systematic review

OBJECTIVES

This systematic review assessed the influence of online health information (OHI) search behaviour on health and medical decisions.

METHODS

Eligible studies were identified by searching electronic databases PubMed, Scopus, and CINAHL in February 2020 for studies reporting OHI search behaviour and its influence on health decisions. Information was extracted pertaining to either consumers' (self-reported) perceptions of the influence of OHI on decision-making or the association between online search behaviour and health decision-making.

RESULTS

A total of 3995 articles were screened, with 48 included in the final analysis. The reviewed studies indicated that OHI assisted in making subsequent health related decisions such as asking questions during a consultation, increased professional visits, improved adherence to the advice of a physician, being more compliant with taking medication, and improved self-care.

CONCLUSION

Consumers largely used OHI to support information provided by their physicians. The strength of the patient-provider relationship was considered important in moderating the potential negative outcomes of OHI.

PRACTICE IMPLICATIONS

Health care systems have a unique opportunity to direct OHI search behaviours towards empowering consumers to engage as an informed, active and joint decision-maker in their own health care.
