Mobile Health Technology and Healthcare Providers: Systemic Barriers to Adoption
Somayyeh Zakerabasali,Seyed Mohammad Ayyoubzadeh,Tayebeh Baniasadi,Azita Yazdani,Shahabeddin Abhari 대한의료정보학회 2021 Healthcare Informatics Research Vol.27 No.4
Objectives: Despite the growing use of mobile health (mHealth), certain barriers seem to be hindering the use of mHealthapplications in healthcare. This article presents a systematic review of the literature on barriers associated with mHealthreported by healthcare professionals. Methods: This systematic review was carried out to identify studies published fromJanuary 2015 to December 2019 by searching four electronic databases (PubMed/MEDLINE, Web of Science, Embase, andGoogle Scholar). Studies were included if they reported perceived barriers to the adoption of mHealth from healthcare providers’perspectives. Content analysis and categorization of barriers were performed based on a focus group discussion thatexplored researchers’ knowledge and experiences. Results: Among the 273 papers retrieved through the search strategy, 18works were selected and 18 barriers were identified. The relevant barriers were categorized into three main groups: technical,individual, and healthcare system. Security and privacy concerns from the category of technical barriers, knowledge andlimited literacy from the category of individual barriers, and economic and financial factors from the category of healthcaresystem barriers were chosen as three of the most important challenges related to the adoption of mHealth described in the includedpublications. Conclusions: mHealth adoption is a complex and multi-dimensional process that is widely implementedto increase access to healthcare services. However, it is influenced by various factors and barriers. Understanding the barriersto adoption of mHealth applications among providers, and engaging them in the adoption process will be important for thesuccessful deployment of these applications.

This paper deals with the simulation-based design optimization and experimental validation of the characteristics of an in-core silver Self-Powered Neutron Detector (SPND). Optimized dimensions of the SPND are determined by combining Monte Carlo simulations and analytical methods. As a first step, the Monte Carlo transport code MCNPX is used to follow the trajectory and fate of the neutrons emitted from an external source. This simulation is able to seamlessly integrate various phenomena, including neutron slowing-down and shielding effects. Then, the expected number of beta particles and their energy spectrum following a neutron capture reaction in the silver emitter are fetched from the TENDEL database using the JANIS software interface and integrated with the data from the first step to yield the origin and spectrum of the source electrons. Eventually, the MCNPX transport code is used for the Monte Carlo calculation of the ballistic current of beta particles in the various regions of the SPND. Then, the output current and the maximum insulator thickness to avoid breakdown are determined. The optimum design of the SPND is then manufactured and experimental tests are conducted. The calculated design parameters of this detector have been found in good agreement with the obtained experimental results.
