Evaluating the Quality of a Clinical Mobile App for Physicians' CT Scan Ordering Using the MARS Rating Scale.

Given the lack of literature on the contributing factors to adopt mobile applications (apps) among physicians and the crucial role of the quality of the apps in their widespread use, the aim of this study is using the Mobile App Rating Scale (MARS) to evaluate the quality of the head CT scan appropriateness criteria app(HAC app). It was developed to assist medical interns and residents in ordering head CT scans. MARS is internationally recognized as an app rating tool and consists of four objective and subjective quality subscales quality subscale. Although the overall quality score of the HAC app was favorable (82 out of 100), it had low quality scores in the "information" (73.37 out of 100) and the "engagement" (73.48 out of 100) subscales. The HAC app appears to be functional to the physicians; however, it needs to improve its quality in terms of interactivity and effectiveness.
