ISLAMABAD:A new randomised clinical trial has found that smartphone application performs better than traditional exam in cardiac assessment.
According to a University of Ottawa Heart Institute-led research, a smartphone application using the phone’s camera function performed better than traditional physical examination to assess blood flow in a wrist artery for patients undergoing coronary angiography.
These findings highlight the potential of smartphone applications to help physicians make decisions at the bedside. “Because of the widespread availability of smartphones, they are being used increasingly as point-of-care diagnostics in clinical settings with minimal or no cost,” said researcher Benjamin Hibbert.
The researchers compared the use of a heart-rate monitoring application with the modified Allen test, which measures blood flow in the radial and ulnar arteries of the wrist, one of which is used to access the heart for coronary angiography.
A total of 438 participants were split into two groups; one group was assessed using the app and the other was assessed using a gold-standard traditional physical examination (known as the Allen test). The smartphone app had a diagnostic accuracy of 94 percent compared with 84 percent using the traditional method.
“The current report highlights that a smartphone application can outperform the current standard of care and provide incremental diagnostic yield in clinical practice,” wrote Hibbert with colleagues.
“Although this application is not certified at present for use in health care by any regulatory body, our study highlights the potential for smartphone-based diagnostics to aid in clinical decision-making at the patient’s bedside,” concluded Hibbert.
