Aims: This research aims to systematically review the current clinical evidence of the efficacy of mobile phone reminders on retention to care among HIV patients. This study also seeks to determine an effect size of the intervention and presents implications for future studies.

Background: Use of mobile technologies is an innovative and affordable approach to HIV prevention and care, particularly in resource limited settings. Approximately two-thirds of people who are initially diagnosed with HIV are lost to follow-up before starting HIV treatment in low and middle-income countries, posing serious global health concerns. While mobile text message reminders for HIV medication adherence have shown positive health outcomes, it is not well understood whether the reminders can also improve patients' retention to care.

Methods: The authors conducted a meta-analysis of literature in the following databases: PubMed, CINAHL, ProQuest, and Web of Science. Of the 667 peer-reviewed research articles reviewed, nine studies were included in the final analysis. Stata version 13 was used for the analysis.

Results: Nine studies (5 randomized controlled and 4 before and after studies) from 7 countries included 3,004 HIV patients. Random-effect meta-analysis (I-squared = 94.1%) found that HIV patients who received mobile phone reminders for their follow-up appointments were two times more likely to return to care than those who didn't receive reminders (pooled odd ratio (OR)=2.04, 95% CI: 0.97-4.27). Our sub-group analysis of 5 randomized controlled studies showed a significant effect of mobile phone reminders (OR=2.04, 95% CI: 1.11-3.74). Six studies in Africa showed that HIV patients (mostly women) receiving mobile phone reminders were three times more likely to return to care than those who received no reminders (OR=2.92, 95% CI: 1.13-7.53).

Conclusion: Mobile phone reminders are an effective intervention to improve retention to HIV care. Women with HIV living in resource limited settings benefit significantly from the intervention. Also, mobile phone reminders using text messages are as effective as phone calls to improve retention to HIV care.

Background: The ability to obtain high quality ocular images utilizing smartphone technology is of special interest in under-resourced parts of the world where traditional ocular imaging devices are cost-prohibitive, difficult to transport, and require a trained technician for operation.

Purpose: The purpose of this study was to explore potential anterior and posterior segment ocular imaging use cases for a smartphone-based ophthalmic camera adapter (Paxos Scope, Digisight Technologies, San Francisco, CA, USA) in under-resourced settings in Nepal.

Methods: From September to November of 2015 we utilized the Paxos Scope smartphone camera adapter coupled with an iPhone 5 to explore anterior and posterior segment clinical applications for this mobile technology. We used the device at a tertiary eye care facility, a rural eye hospital and a rural cataract outreach camp. We tested the device's capability for high quality photo-documentation in clinic, in the operating room, and in the outreach camp setting. Images were automatically uploaded to a secure, cloud-based electronic medical record system that facilitated sharing of images with other providers for telemedicine purposes.

Results: Herein we present 17 ocular images documenting a wide variety of anterior and posterior segment pathology using the Paxos Scope from clinical cases seen in a variety of settings in Nepal.

Conclusions: We found the quality of both the anterior and posterior segment images to be excellent in the clinic, the operating room, and the outreach camp settings. We found the device to be versatile and user-friendly, with a short learning curve. The Paxos Scope smartphone camera adapter may provide an affordable, high-quality, mobile ocular imaging option for under-resourced parts of the world.
