  1. 1. Social innovation: incentives from “push” to people Last mile delivery in health care and patient empowerment through technology: the case of “Telecommunication for Health” Article by Roberto Tapia-Conye (pictured), Director-General, Carso Health Institute – Carlos Slim Foundation, Mexico, and Rodrigo Saucedo, Researcher, Carso Health Institute – Carlos Slim Foundation, Mexico he epidemiologic profile of the population in Latin therefore limits the success of any treatment. It is necessary T America has been continuously changing for the last 30 years. Noncommunicable diseases have emerged as the main burden of national health systems, shifting the to shift from acute discrete interventions to preventive continuous care, integrating hospital-based interventions with community participation. pattern from the youngest population to the eldest e.g. The second major turnaround refers to the degree of diabetes, cardiovascular diseases and obesity. The average involvement of patients with respect to their own disease. It mortality rate from diabetes mellitus (DM) in Latin America1 is estimated that only 50% of patients comply with their is 35 with the extreme cases of Mexico (83.1) and Uruguay physicians’ prescription irrespective of the disease or their (14)2,3. The International Diabetes Federation estimated that age10. Treatment of chronic diseases requires an intake of in 2007 there were 20.7 million people with DM and several doses of medication on a daily basis, and there is an impaired glucose tolerance whereas in 2025 there will be inverse linear relation between the number of doses and the 41.2 miliion people; this is a 99.2% growth rate. In fact, levels of compliance11. Additionally, people discontinue their WHO estimates that in 2030 nine out of the ten main causes medicine intake within a period of time; patients suffering of death will be attributable to noncommunicable diseases4. from hypertension generally discontinue their medication Research into causes of this increase does not point a linear intake in 90 days12. On the other hand, the ageing of the cause. A sedentary lifestyle and bad diet have been pointed population plays a key role. In Latin America life expectancy to as the main driving forces5.

The number of people This scenario is immersed in a context of globalization and living with HIV/AIDS in Latin America has grown from 1.3 immigration, which limits the capacity of national health million in 2000 to 1.6 million in 2007; a 20.9% growth systems to provide continuous and sustained health rate7. Thus, the analysis is now between acute and chronic treatment. Health systems must be able to provide mobile diseases8. The centre of the analysis in public health is now on morbidity rather than on mortality9. At the Carso Health Institute, an initiative of the Carlos Slim Foundation, we argue 80 that chronic diseases are conditions of life and an effective 78 76 strategy must integrate health services through multiple 74 bidirectional channels of communication so that the patient, 72 70 the physician and the health system can continuously interact. 68 For the strategy to be effective, we believe that a major 66 64 turnaround is required at two different levels: at the health 62 system-level and at the patient-level. First, there must be a 60 1970-1975 1975-1980 1980-1985 1985-1990 1990-1995 1995-2000 2000-2005 2005-2010 2010-2015 2015-2020 2020-2025 2025-2030 change in the way traditional health services are provided. The current system is hospital-centric, it works on a one-to- one interaction and it is limited in the time of interaction between the physician and the patient. Patients are still Source: UN Population Division passive recipients of vertical and reparative interventions.

In the US, for diabetes alone, the total 150 cost of treatment and complications was 132 billion in 100 2002, and it will grow at an annual rate of 3.3% to 192 50 billion in 202014.

Source: ITU 2008 Thus, governments are now struggling to find a new way Figure 2: Number of fixed lines and mobile phone users in Latin America, 1999–2008 to approach chronic diseases. We believe that technology is the agent of change for the current paradigm in the delivery of health services. In Latin America the use of technology is 200 180 increasingly becoming a part of people’s everyday lives. In 160 1999 there were 62.7 million fixed phone lines in Latin Millions 140 America, increasing to 99.4 in 2008. With respect to mobile 120 phone users, there were 19 million in 1999, and it 100 dramatically increased up to 374.9 million in 2008 for an 80 60 average of 80 mobile phone users per 100 inhabitants 40 (Figure 2). Some factors explain this. Firstly, mobile phones 20 require wireless infrastructure only. Secondly, mobile phones 0 can be purchased without any credit conditions. 1990 2000 2001 2002 2003 2004 2005 2006 2007 2008 With respect to personal computers (PCs), in 1999 there Number of PCs Internet users were 18.6 million PCs in Latin America, increasing to almost Source: ITU 2008 87 million in 2008, a growth rate of 368% in only 9 years. Figure 3: Number of PCs and Internet users in Latin America, Nevertheless, the trend is much steeper for Internet users. 1999–2008 There were 9.97 million Internet users in 1999, increasing to 183.5 million in 2008, 17.4 times the number of users found out that 93% of SMS-based interventions delivered in 1999. Two possible factors explain this. Firstly, a single PC positive behaviour changes22. He found that dialogue may be used by more than one person in a household; initiation, continuous interactivity and customization of SMS secondly, the number of public Internet kiosks has risen were highly effective; this is consistent with a 2003 WHO dramatically since 2000, as is the case in Mexico17. study in which motivation and behavioural skills were The use of technology to deliver health services is now a described as the main drivers of compliance23.

For us, mHealth does not refer to the use of mobile through multiple bidirectional channels of devices to provide a health service; it refers to mobilizing the communications, setting the patient at the centre health resources to wherever the user goes, literally following of the analysis. him and enhancing the probability of a treatment succeeding. It is necessary to change the current paradigm of With Telecommunication for Health it is the user that provision of health services, from acute discrete demands results from the health system, setting a new interventions to continuous preventive care, bidirectional channel of communication and empowering him integrating hospital-based interventions into a to take further action. These innovations are available even in nonspatial environment. the poorest communities.
