Using Mobile Phones to Ensure that Referred Tuberculosis Patients Reach Their Treatment Facilities: A Call that Makes a DifferenceChoun, K; Achanta, S; Naik, B; Tripathy, J; Thai, S; Lorent, N; Khun, K; van Griensven, J; Kumar, A; Zachariah, R (BioMed Central, 2017-08-22)Over the last decade, the availability and use of mobile phones have grown exponentially globally and in Cambodia. In the Sihanouk Hospital Centre of Hope(SHCH) in Cambodia about half of all tuberculosis patients referred out to peripheral health facilities for TB treatment initiation or continuation were lost to contact after referral ranging from 19 to 69% between 2008 and 2013. To address this, we implemented a mobile phone-based patient tracking intervention. Here, we report the number and proportion of referred TB patients who could be contacted through a mobile phone and retained in care after the introduction of mobile phone tracking.
