Its experimental approach and clinical set up, however, offers remedies to the weaknesses. Consequently, it can be used to inform a research study or to develop knowledge on operation safety from radiations. The sample consisted of a radiology fellow, who was involved in all of the investigated procedures, and 21 anesthesiology residents. Sixteen of the residents were primary clinicians in single procedures while the remaining five residents were primary clinicians in more than one procedure. The maximum number of procedures for a resident was four.

The clinicians had been trained on radiology safety prior to the study. The level of evidence that lack of randomization and control characterizes is a threat to validity and reliability of the study. Another limitation is the small sample size, for a quantitative study. Strengths of the study such as use of laboratory equipments that are accurate and presumed personnel diversity within the facility of study remedies the limitations. The study can, therefore, be used as a source of information for further scientific research and to inform practices in radiology procedures.

The study aimed at making a vibro-tactile display and to investigating effectiveness of vibro-tactile display, through “identification rate, accuracy, response rate, ease of learning, and feedback,” and to compare the display with auditory alarm (p. 1723). The study had multiple purposes that are to explore types of radiation and possible biological effects of radiations, to discuss radiation quantity and units of measurement, and to review measurement of radiation exposure and safe range of exposure.

Other objectives were to discuss risk of exposure to pregnancy, measures for mitigating exposure, and to develop knowledge on the ALARA concept. The author does not disclose approach to recruitment an selection of reviewed literature and this could conceal possible bias. Bias in interpretation of reviewed
