We also validated both digital contact tracing tools by verifying the physician-patient contacts with the electronic medical records of 156 patients who attended the NCID screening center over a 24-hour time frame within the study period. Results: RTLS tags had a high sensitivity of 95.3{\%} for detecting patient contacts identified either by the system or TraceTogether while TraceTogether had an overall sensitivity of 6.5{\%} and performed significantly better on Android phones than iPhones (Android: 9.7{\%}, iPhone: 2.7{\%}; P<.001). When validated against the electronic medical records, RTLS tags had a sensitivity of 96.9{\%} and specificity of 83.1{\%}, while TraceTogether only detected 2 patient contacts with physicians who did not attend to them. Conclusions: TraceTogether had a much lower sensitivity than RTLS tags for identifying patient contacts in a clinical setting. Although the tag-based RTLS performed well for contact tracing in a clinical setting, its implementation in the community would be more challenging than TraceTogether. Given the uncertainty of the adoption and capabilities of contact tracing apps, policy makers should be cautioned against overreliance on such apps for contact tracing. Nonetheless, leveraging technology to augment conventional manual contact tracing is a necessary move for returning some normalcy to life during the long haul of the COVID-19 pandemic.
