How often have you forgotten to take your medicine? Imagine if you needed an I-phone app to keep track of all of them. Well, you are not alone. The World Health Organization estimates that only around 50% of patients take their medications as prescribed (NCPIE, 2007). Non-adherence can affect people with diverse demographics and can lead to a myriad of problems associated with morbidity and mortality (NCPIE, 2007). It is responsible for 125,000 deaths annually and costs the health care industry billions of dollars (NCPIE, 2007). Numerous studies have linked social support to medical adherence. But regrettably, few published studies have utilized the power of social networks to tackle this question.
Using the social network approach, the type of ties is influential in patient adherence. Granovetter argues that “weak ties are channels through which ideas, influence, or information socially distant from the ego may reach him/her” (Granovetter, 1973). In a nutshell, if a person has less invested in you, he may serve as the ideal conduit for giving support. I am just invested enough to care and not too much to sabotage or overpower your life. A study conducted by Osamor and Owumi in 2011 showed that among patients with hypertension or health complications related to hypertension, having a family member who were concerned about their condition or helpful in reminding them about taking appropriate medications corresponded to adherence rates of 61.1% and 61.5% respectively (Osamor and Owumi, 2011). However, having friends in your back pocket to remind you to take medication had the greatest effect on medication adherence (Osamor and Owumi, 2011).
While friends appeared to be protective for a chronic disease such as hypertension, for a stigmatized disease such as HIV, they may be cause for concern. Controlling the replication of HIV is linked to staying on cocktail meds. HIV medication adherence is an example where the complicated, exhausting regimen may lead to far too many med holidays and eventual permanent medication drop-outs. Kelly et. al performed a study in 2012 to analyze the role of social support networks and its effect on antiretroviral adherence among HIV infected drug users. The study showed that the participants had an average of 1.36 social network members that can be insular from outside influence. These albeit small networks were likely to have an alter that was either HIV -positive or a drug user (Kelly et. al, 2012). Among these participants, 25% had at least one person within their network who was infected with HIV and 34% had at least one drug user within their network (Kelly et. al, 2012). The clincher is small isolated networks coupled with the presence of a drug user and/or HIV infected person within the participants’ network was linked to lower rates of antiretroviral medication adherence (Kelly et. al, 2012). While it may appear intuitive to rely on those closest to us (his or her network), HIV infected friends themselves may be struggling with their own adherence and less equipped to give support for your own. Likewise, drug using is likely take over daily healthful maintenance of any kind. Using social networks to explore medication adherence is a wide open field. But medication adherence proves that no two diseases or networks are alike.
