Ask, don't tell - mobile phones to improve HIV care

November 7, 2013

Almost all health care is voluntary: patients choose when to engage in care, when to take their medicine (if they choose to take it), and whether to return for follow-up visits. In human immunodeficiency virus (HIV) infection and other chronic diseases, the benefits of medication adherence for the patient and public health are tremendous. [...]

Effects of a mobile phone short message service on antiretroviral treatment adherence in Kenya (WelTel Kenya1): a randomised trial

November 10, 2010

Mobile (cell) phone communication has been suggested as a method to improve delivery of health services. However, data on the effects of mobile health technology on patient outcomes in resource-limited settings are limited. We aimed to assess whether mobile phone communication between health-care workers and patients starting antiretroviral therapy in Kenya improved drug adherence and suppression of plasma HIV-1 RNA load.

#5: Cell phones continue to change how Africans live.

The devices have proven to be invaluable: health-care workers use cell phones to track and monitor pregnant women in rural Rwanda (where the number of maternal deaths is high) and H.I.V. patients in Kenya, and Kenya’s mobile banking system, which has been called the world’s most innovative, lets Kenyans pay bills, send remittances, purchase goods and airtime, move funds among accounts, and even take out and pay back loans for entrepreneurial ventures.


The convergence of mobile telephony and health care is under way

BILL GATES seems to relish being the skunk at the garden party. The former boss of Microsoft, now a global-health philanthropist, was invited to address a big “m-health” conference in Washington, DC, this week. Some 2,400 proponents of delivering health services over wireless telecoms, from the private and public sectors, gathered to celebrate the dozens of pilot projects under way around the world.[...]
