Introduction: Smartphones have become an essential part of our lives. There is anecdotal evidence that health professionals are increasingly using Smartphones during their work. Smartphone use in healthcare work settings presents both opportunities and challenges. Using smartphones during clinical practice causes lack of attention, diminished capacity to remember important information, and a decrement in performance which might impact the quality of treatment provided. Aims: The objective of the study is to determine the impact of smartphone usage on the quality of treatment provided by the physiotherapists and the physiotherapy interns during the treatment sessions in OPD__ampersandsignrsquo;s. Methodology: A descriptive design with convenience sampling and a self-designed questionnaire with close-ended questions were used to survey 120 PTs and PT interns working in various healthcare sectors. The questionnaire was based on various validated instruments for assessing the frequency and purpose, perception and opinion regarding the usage of smartphones during treatment. Results: In the present study, the statistical analysis showed that there is a significant difference in the frequency and purpose of smartphone usage during treatment among the groups with p value__ampersandsignlt;0.002 and the perception and opinion regarding the usage of smartphones among the two groups with p-value __ampersandsignlt;0.001. The physiotherapy interns scored higher in both sections. A positive correlation is found between frequency/purpose and perception/attitude among physiotherapy interns. Conclusion: The study concluded that smartphone usage while giving a treatment can alter the quality of treatment provided to the patient by the physiotherapy interns. The majority of the physiotherapy interns believe that smartphone usage while giving treatment may impact the quality of treatment during the treatment session.
