Currently, not only in Caldas, but also in many undeveloped countries, the adherence of patients, regardless of their income, to treatments is a challenge. One specific case is TB. Even being this disease a curable one, it has been impossible to eradicate, one of the causes being low adherence of people to long term treatments. Changing this will improve the healthcare status of the population, not only for infectious diseases, but also for chronic ones. It is a fact that despite the income, more and more people around the globe have a mobile phone. This devices have enough computing power to run small apps aimed to remember patients to take their meds.
Improving healthcare can be achieved in many ways, but in undeveloped countries, despite the difficulties, many people manage to access the health care system. Getting, usually, proper diagnoses and many times, being provided with the medications they need. This is the case of Tuberculosis, a treatable and curable disease, that because of many reasons still remains a problem in undeveloped nations, specially those where people living in poorness and/or malnutrition is prevalent.
Many patients fail to complete or take their meds in the proper frequency, not only because of lack of access, but also because either they "already feel fine," or because they have more than a couple of meds to take daily and confuse the doses, specially the elderly. Those patients with chronic diseases like diabetes, COPD, coronary diseases, or infectious diseases, may benefit from applications in their phones helping them remember not only to take some pill, but also how does that pill looks like (very important for patients with cognitive issues)
It is also a fact that giving patients feed back on their treatments increases the adherence rate, make them feel better and help them achieve and complete treatments. In the case of a person with TB, if that person is properly treated, the spread of the disease will be stopped and it will impact the healthcare of the entire family.
This kind of apps could also help remember moms bring their kids for vaccinations (a very common problem) at the right moment, and not only when the kid is sick. They may also help remember women to perform self exams on their breasts, or to go (yearly) to the doctor to get the pap smear.
One single app in a phone, could help many improve their health.
