RESUMEN
Tuberculosis (TB) contact tracing is typically conducted in resource-limited settings with paper forms, but this approach may be limited by inefficiencies in data collection, storage, and retrieval and poor data quality. In Botswana, we developed, piloted, and evaluated a mobile health (mHealth) approach to TB contact tracing that replaced the paper form-based approach for a period of six months. For both approaches, we compared the time required to complete TB contact tracing and the quality of data collected. For the mHealth approach, we also administered the Computer System Usability Questionnaire to 2 health care workers who used the new approach, and we identified and addressed operational considerations for implementation. Compared to the paper form-based approach, the mHealth approach reduced the median time required to complete TB contact tracing and improved data quality. The mHealth approach also had favorable overall rating, system usefulness, information quality, and interface quality scores on the Computer System Usability Questionnaire. Overall, the mHealth approach to TB contact tracing improved on the paper form-based approach used in Botswana. This new approach may similarly benefit TB contact tracing efforts in other resource-limited settings.

BACKGROUND: Mobile learning (mLearning) uses wireless networks and mobile devices to expand physician trainees' and healthcare providers' access to and exchange of medical information. Opportunities to increase implementation and expand use of mobile devices to support health care information access and delivery in Africa are vast, but the rapid growth of mLearning has caused project implementation to outpace objective measurement of impact. This study makes a contribution to the existing body of literature regarding mLearning implementation in Africa through its focus on the use of smart devices (tablets) in undergraduate medical education and medical students' perceptions of the effects on their learning environment. MATERIALS AND METHODS: The population of this prospective mixed-methods study consisted of 82 undergraduate medical students (45 third year and 37 fourth year) at the University of Botswana Faculty of Medicine. They received tablets in the earliest phase of the mLearning project implementation (between November 2012 and January 2013), when they were in the third and fourth year of their medical training. Usage of the tablets was assessed both quantitatively and qualitatively, through both application usage tracking and focus groups. RESULTS: Based on application usage data and coding and analysis of focus group discussions, undergraduate medical students indicated that tablets were useful in their medical education, allowing them continual access to information and opportunities for communication. Participants noted that the primary barrier to use of tablets was the lack of mobile cellular Internet beyond the Wi-Fi zones at the training sites. Moreover, participants offered suggestions for improvements to the implementation process. CONCLUSIONS: Even in resource-limited settings where Internet access can be unreliable and intermittent, the adoption of tablets can have benefits to medical education by providing consistent access to extensive and current medical information resources. This study highlights the value of clinical resources with offline functionality, with or without consistent access to the Internet. There is also the potential for optimizing the use of tablets through improved training and technical support.

Mobile telemedicine involves the use of mobile device (e.g., cell phones, tablets) technology to exchange information to assist in the provision of patient care. Throughout the world, mobile telemedicine initiatives are increasing in number and in scale, but literature on their impact on patient outcomes in low-resource areas is limited. This study explores the potential impact of a mobile oral telemedicine system on the oral health specialty referral system in Botswana. Analysis of 26 eligible cases from June 2012 to July 2013 reveals high diagnosis concordance between dental officers and oral health specialists at 91.3% (21/23) but significant management plan discordance at 64.0% (16/25), over two-thirds of which involved the specialists disagreeing with the referring clinicians about the need for a visit to a specialist. These findings suggest mobile telemedicine can optimize the use of insights and skills of specialists remotely in regions where they are scarce.

Although Botswana has recently been categorised as an upper middle income country, it is burdened by a scarcity of resources, both human and technological. There are barriers to patients' access to specialized care and healthcare providers' access to medical knowledge. Over the past three years, the Botswana-University of Pennsylvania Partnership (BUP) has piloted four mobile telemedicine projects in the specialties of women's health (cervical cancer screening utilizing visual inspection with acetic acid), radiology, oral medicine and dermatology. Mobile telemedicine has been used in 11 locations in Botswana, training a total of 24 clinicians and successfully contributing to the management of 643 cases. In addition to mobile telemedicine, BUP has initiated an m-learning programme with the University of Botswana School of Medicine. While successfully providing patients and providers with improved access to healthcare resources, the m-health projects have faced numerous technical and social challenges. These include malfunctioning mobile devices, unreliable IT infrastructure, accidental damage to mobile devices, and cultural misalignment between IT and healthcare providers. BUP has worked with its local partners to develop solutions to these problems. To ensure sustainability, m-health programmes must have strategic goals that are aligned with those of the national health and education system, and the initiatives must be owned and led by local stakeholders. Whenever possible, open source technology and local IT expertise and infrastructure should be employed.

Mobile telemedicine, which involves the use of cellular phone telecommunications to facilitate exchange of information between parties in different locations to assist in the management of patients, has become increasingly popular, particularly in resource-limited settings. In Botswana, small studies of mobile telemedicine programs suggest access to these services positively affect patients, but these programs' impact is difficult to capture given limitations of baseline and comparative data. Our observational study uses each patient receiving mobile oral telemedicine services in Botswana as his/her own control to assess the impact of these services on his/her diagnosis and management plan. At month 5 of 12 total, preliminary analysis of eligible cases (n = 27) reveals management plan discordance between clinicians submitting cases and the specialist was 68.0% (17/25), suggesting that telemedicine can result in significant changes in management of patients.

Tuberculosis remains a leading cause of morbidity and mortality worldwide. In 2011, there were 8.7 million new cases and 1.4 million deaths from the disease, with >95% of these deaths taking place in low- and middle-income countries [1]. Contact tracing prevents the spread of tuberculosis by identifying and screening a case's contacts and referring symptomatic individuals to health care providers. Traditionally, contact tracing has been conducted with paper forms, which can lead to considerable inefficiencies in data collection, storage, and retrieval. These inefficiencies are problematic as tuberculosis can continue to spread if disruption of disease transmission is delayed. Mobile health approaches to tuberculosis contact tracing remain largely unaddressed and limited to management and monitoring of multidrug-resistant tuberculosis [2].To address these limitations, a mobile health application that digitizes and automates contact tracing was developed. This poster presents work currently underway to evaluate this new approach in Botswana, which has the tenth highest incidence rate of tuberculosis in the world [3]. Operational considerations for implementing a mobile health approach to contact tracing in resource-limited settings are also presented.
