IntroductionA mobile app may increase the reporting of adverse drug reactions (ADRs) and improve the communication of new drug safety information. Factors that influence the use of an app for such two-way risk communication need to be considered at the development stage.ObjectiveOur aim was to reveal the factors that may influence healthcare professionals (HCPs) and patients to use an app for two-way risk communication.MethodsFocus group discussions and face-to-face interviews were conducted in the Netherlands, Spain and the UK. Patients with type 2 diabetes mellitus, patients with a rare disease or their caregivers and adolescents with health conditions were eligible to participate. HCPs included pharmacists, paediatricians, general practitioners, internists, practice nurses and professionals caring for patients with a rare disease. Patients and HCPs were recruited through various channels. The recorded discussions and interviews were transcribed verbatim. The dataset was analysed using thematic analysis and arranged according to the Unified Theory of Acceptance and Use of Technology.ResultsSeven focus group discussions and 13 interviews were conducted. In total, 21 HCPs and 50 patients participated. Identified factors that may influence the use of the app were the type of feedback given on reported ADRs, how ADR reports are stored and the type of drug news. Also mentioned were other functions of the app, ease of use, type of language, the source of safety information provided through the app, security of the app, layout, the operating systems on which the app can be used and the costs.ConclusionsFurther research is needed to assess associations between user characteristics and the direction (positive or negative) of the factors potentially influencing app use.Electronic supplementary materialThe online version of this article (doi:10.1007/s40264-016-0494-x) contains supplementary material, which is available to authorized users.

IntroductionPreviously, an app has been developed for healthcare professionals (HCPs) and patients to report adverse drug reactions (ADRs) to national medicines agencies and to receive drug safety information.ObjectiveThis study aimed to assess (1) European HCPs’ and patients’ interest in an app for this two-way risk communication; (2) their preferences and perceptions towards specific app characteristics; and (3) which HCPs and patients are particularly interested in the app. In addition, these aspects were studied specifically for the countries where such an app was already available, i.e. Croatia, The Netherlands, and The UK.MethodsEuropean HCPs and patients were asked to complete a web-based survey developed in the context of the Web-Recognizing Adverse Drug Reactions (Web-RADR) project. Data on app interest and preferences and perceptions towards app characteristics were analysed descriptively. Logistic regression analyses were conducted to assess the association of HCP characteristics and patient characteristics on the level of interest in the app (i.e. very interested vs. not/somewhat interested).ResultsIn total, 399 HCPs and 656 patients completed the survey. About half of the patients (48%; ranging from 38% from The Netherlands to 54% from The UK), and 61% of the HCPs (ranging from 42% from The Netherlands to 54% from The UK) were very interested in the app. A faster means of reporting ADRs and easier access to the reporting form were the main perceived benefits. HCPs and patients who already use a health app were particularly interested in the app (HCPs: odds ratio [OR] 3.52; 95% confidence interval [CI] 1.96–6.30, patients: OR 1.64; 95% CI 1.19–2.27).ConclusionsAn app is positively perceived by HCPs and patients for reporting ADRs quickly and for receiving drug safety information from national medicines agencies. In particular, HCPs and patients who already use other health apps were interested in the app.Electronic supplementary materialThe online version of this article (10.1007/s40264-018-0648-0) contains supplementary material, which is available to authorized users.
