The Real India-mHealth & beyond Part 3


Tuberculosis- TB is caused by a bacterium, Mycobacterium tuberculosis, that the WHO says infects one third of the world’s population. Between five and 10 percent of infected people develop the disease and become contagious at some point in their lives. (For those with HIV or AIDS, however, the rate is much higher.)

The Bigger problem- India is the highest TB burden country with World health Organisation (WHO) statistics for 2010 giving an estimated incidence figure of 2.3 million cases of TB for India out of a global incidence of 9.4 million cases. The WHO statistics also show that India is 17th out of the 22 high burden countries in terms of TB incidence rate. The estimated TB prevalence figure for 2010 is given as 3.1 million. It is estimated that about 40% of the Indian population is infected with TB bacteria, the vast majority of whom have latent rather than active TB.
Compliance issues in Treatment- To treat TB, the WHO recommends the so-called DOTS (Directly Observed Treatment Short-course) strategy, where patients take medication under supervision from health staff. Daily supervision of treatment is too demanding for most of our patients and instead implements self-administered therapy with patient education and support to ensure adherence. In many countries affected by conflict, access to health structures is limited for the population. Conflict interrupts travel and makes people fearful of leaving their shelters to seek assistance. It can also lead to the collapse of existing health systems.In India in 2010 292,972 people needed TB re-treatment because of initial treatment relapse, failure or default.

In Focus- Operation ASHA

Operation ASHA is a registered non-profit that has taken TB treatment to the doorsteps of 5.37 million individuals living in disadvantaged areas. It operates in over 2,053 villages and slums in six states spread across India and Cambodia. The effort is self-sustainable and is using technology to reach out to millions everyday.

Establishing Centres- Operation ASHA establishes tuberculosis (TB) treatment centers within existing community locals (for example, strategically placed shops, homes, temples, or health clinics). Under the World Health Organization’s Directly Observed Therapy (DOTS), patients must take their medicines under the supervision of a health care worker. The model is designed to help patients procure their medicines conveniently without wasting time, spending money on transport, and losing wages. This also drastically reduces the effort, time and money that patients have to invest in taking their medication, which is key to ensuring that patients complete the entire course of treatment.

Training- Operation ASHA trains community members (often former patients) to become tuberculosis health workers who are responsible for identifying new patients, ensuring adherence to the drug regimen, and carrying out regular educational campaigns. Operation ASHA works closely with the Government of India, who provides them with free medicines and diagnostic services. After a center has been established for two years, the government provides a grant for every patient cured, making OpASHA’s centers financially self-sustaining.

Building Compliance through technology- Ensuring patient compliance is important because of the threat of multi-drug resistant tuberculosis (MDR-TB), which has become one of the world’s largest public health issues. Resistant strains of the disease can take up to two years to treat (in comparison to the standard 6 month regimen). Second line medicines have more severe side effects and can also cost 50-200 times more. Such unrealistically high costs are essentially a death warrant to those below the poverty line. To combat the rising MDR-TB epidemic, OpASHA launched eCompliance, a biometric initiative in collaboration with Microsoft Research, which uses fingerprint scanners to track patient visits.


The system consists of three parts: 
  • a netbook computer, 
  • a USB fingerprint reader (from Digital Persona), 
  • and a GSM modem that uploads the visitation logs (via SMS) to a central location. 


Patients scan their finger every time they take medication, and these logs are visualized in the central office to monitor medication delivery. Missed doses trigger an SMS notification to managers, who ensure timely supervision or counseling to the patients and health workers involved. The health worker is then required to do a follow-up visit within 48 hours to deliver the medicines and supplementary health education. 

These home visits are also confirmed by biometrics. Currently the terminal is used daily in over 40 treatment centers, spanning Delhi, Mumbai, and Jaitpur; Operation ASHA is aggressively expanding the deployment to over 225 centers around the world. To date, the technology has enrolled about 2,700 patients and logged over 50,000 supervised doses. The biometric records are used to automatically generate reports to the government and other stakeholders.

With the help of eCompliance, Operation ASHA has reduced its default to 1.5%, which is much lower than other institutions. The cost of treating a patient for the entire therapy of is US $50.

Healthcare On Mobiles: Featured post- mHealth fighting malnutrition
Malnutrition is a byword in the forested hills of the Melghat region inhabited mostly by Korku Adivasis. Every year 400-500 children between the ages of 0 and 6 die in the region, comprising Chikhaldhara and Dharni taluks, according to official figures from 2005.


The Problem: Thousands of kids die every year in the tribal area of Melghat (Maharashtra, India) due to lack of medical attention and nutritional support. Increased incidence and rapid spread of infectious diseases such as pneumonia, typhoid, and dysentery are primary cause of high child mortality. Situation worsens during monsoon when the food supplies are low and the communicable diseases are at their peak.

Melghat is also a place known for high infant mortality rate. Some reasons for the health crisis in Melghat include lack of infrastructure, under-equipped and under-staffed public health and ICDS centres, the tradition of early marriages and early mothe…

The Formula of Driver and Demand- Indian Startups story

The healthcare industry is currently experiencing change at an unprecedented rate. Change is not only occurring in the technology used in diagnostics and care delivery, but this change is so fundamental that it could, and likely will, fundamentally alter the business model of the industry.
Today we have fitness bands, healthcare apps, appointment schedulers, health chats and several such means to access healthcare but one thing that all of this does not necessarily correlate with high quality of care or better outcomes. We need to understand that “Not even a Ferrari will get us to our destination without a driver.”Formula of Driver:
Driver = (Need + Incentive) where;
Incentive = (Value + Reward) Need = (Gap + Demand)
To define the best drivers, we need to first address the need. Need might not make economic or business sense but it is the best opportunity to leave an impact. No one remembers how much business a “Mughal-e-Azam” or “Usual suspects” did but everyone remembers that these were…

Why we never noticed ZIKA?- Indian Research and Development

“Zika had 'disappeared' because it wasn’t worth worrying about and people weren’t paying attention.”

Zika virus was first identified in 1947 in a sentinel monkey that was being used to monitor for the presence of yellow fever virus in the Zika Forest of Uganda. At this time cell lines were not available for studying viruses, so serum from the febrile monkey was inoculated intra-cerebrally into mice. All the mice became sick, and the virus isolated from their brains was called Zika virus. The same virus was subsequently isolated from Aedes africanus mosquitoes in the Zika forest.

In 1950, when some serological studies were being done, it was found that we humans developed antibodies against this virus. Further studies revealed evidence of infection in other African countries, including Uganda, Tanzania, Egypt, Central African Republic, Sierra Leone, and Gabon, as well as Asia (India, Malaysia, Philippines, Thailand, Vietnam, Indonesia). The virus circulating in Brazil is an Asi…
