“…Previous studies have demonstrated the various advantages and improvements that Internet and Mobile Technology has brought to the health care sector; for instance, increasing accessibility for populations facing barriers to health care access, especially those in remote and rural areas, improving health care accessibility, efficiency, and the quality of health care, and reducing queuing and waiting time at the hospital (5,7,(9)(10)(11). Yet, mobile technologies also bring challenges related to health care access.…”

The study explores older people's perceptions and experiences with mobile technology adoption in hospitals. Twenty nine older people were interviewed at a tertiary hospital in Guangzhou from June to December 2020. All the interviews were analyzed using thematic analysis. Older people are a diversified group. Various factors impact their readiness for technology use, including their educational level, age, past experiences, living arrangements, etc. The older people in this study in general expressed a great concern about using the new health technology and many encountered barriers to its successful adoption. Yet, the barriers and difficulties that they encountered are embedded in a changed social context in China. The findings above provide insights into the adoption of health technology, and tailored measures to facilitate older people's technology adoption are suggested.

“…It is estimated that more than 471 million diagnostic X-ray procedures were performed in the United States in 2008, up from 267 million in 1998 [3]. While ionizing radiations has revolutionized medical diagnosis, their use is associated with adverse health effects, especially increasing the life time risk for developing cancer [1,2,[6][7][8][9][10][11][12]. Therefore, it is necessary to reduce radiation exposure of patients as low as possible [13][14][15][16].…”

Shielding has been recommended as an effective tool against radiation exposure. Several studies have published on the availability and use of shielding tools in diagnostic X-ray centers across the country and contradictory results been reported. Therefore, the aim of this systematic review was to find out the status of radiation protection in term of availability and use of shielding tools in diagnostic X-ray centers in Iran. An extensive literature search was conducted in the PubMed/Medline, Embase, ISI, Cochrane Library, SID, Magiran, IranMedex, Irandoc and Google-Scholar search engine. We also manually searched the reference lists of the relevant studies. Two authors independently assessed the eligibility of all studies and extracted data. Thirty-seven studies published from 1998 to 2019 were included in this systematic review. In all, 1089 diagnostic X-ray centers, 4439 radiographs and performance of 1472 radiographers were covered in these studies. The availability of lead apron, gonad shield and thyroid collar were ranged from 7 to 95.5%, 26.6 to 94% and 7 to 94%, respectively. Moreover, their usage was ranged from 0 to 85.5%, 0 to 35% and 0 to 38.4%, respectively. In addition, lens shield was discussed in one study with availability of 0%. During 1998 to 2019, the status of shielding had not improved across the country. Therefore adherence to the safety guideline as far as possible is required to protection patients from undue exposure to radiation.

“…Radiation protection and image quality are two fundamental principles of radiology science. 20 Our results indicate that, where a gonadal shield is used, its positioning is adequate in 99.4% (169 of 170) of radiographs of girls and 59.7% (92 of 154) of radiographs Although the actual positioning of the shield was unsatisfactory in 73 radiographic images of boys, the image quality was considered acceptable in 62 images because the bismuth fringe allowed diagnostic evaluation (Figure 1). In a similar study with a traditional lead shield, 6 gonadal shields were used in only 5.4% of girl and 16.4% of boy pelvic radiographs; unsatisfactory shield positioning was found in 84.3% and 55.3% and repeat imaging required in 21.5% and 10.6% of these cases, respectively.…”

Objective: Traditional lead gonadal shields may not be effective to reduce radiation exposure, owing to poor compliance from radiographers and frequent repeated examinations due to obscured diagnostic areas. This study aimed to evaluate the effect of bismuth shields on image quality during paediatric pelvic radiography. Methods: We previously developed bismuth radioprotective gonadal shields for use in paediatric pelvic radiography at our institution. We retrospectively retrieved and reviewed radiographic images from an existing digital image library. All images were examined for the presence and accurate positioning of gonadal shields. The diagnostic image quality was assessed by an experienced evaluation panel with selected imaging criteria adapted from the European guidelines. Results: A bismuth shield was present in 154 of 198 radiographs of boys and in 170 of 182 radiographs of girls. In boys, the shield protected the testes area adequately in 92 images and partially in 51 images. The shield obscured the remaining 11 images, rendering image quality suboptimal according to the European guidelines. In girls, the shield protected the ovaries adequately in 169 images and partially in one image. No significant differences were seen between the quality of shielded and non-shielded images. Conclusion: Our study demonstrated that these shields do not have a detrimental effect on image quality and can be recommended for routine use.
