Adherence & Behavioral Science
Adherence – or the way patients follow and keep up with medical treatments, is an important aspect to improve the health of the overall population. At Abbott, we are taking a unique approach to improving adherence, so that we can help patients live better.
Despite numerous medical advances and new medicine launches, control over various chronic diseases has not improved, driven primarily by non-adherence to treatments 1,2
of patients never fill their
of patients do not take
their treatments as directed.5
of patients stop their
treatments earlier than recommended.4
Non-adherence has a devastating social and economic impact
Poor adherence contributes to 200,000 premature deaths in Europe per year.4
125 billion euro per year in excess healthcare services in Europe, and in the US 105 billion USD per year in avoidable hospitalizations alone.4
Non-adherence is a multidimensional challenge driven by varied factors including :
- Inadequate knowledge about therapy
- Poor communication with healthcare professionals6
- Cultural beliefs
- Fear of side-effects
- Lack of belief in treatment need6
- Lack of visible benefit in long-term treatments
- Complex dosing schedules6
- Financial worries
- Lack of access to healthcare6
Lack of access to medical care is a key healthcare challenge in emerging markets.
Concentration of healthcare resources in urban areas
83.5% of doctors in Thailand are based in urban areas7. In India 59.2% of healthcare workers are concentrated in urban areas, where only 27.8% of the population resides.8
Primary care consultations last a very short time for half the world’s population9
Time spent with a doctor is important to help explain a condition and share important treatment information.
But it is quite limited – doctors only spend 1.5 min with their patients in India, compared to 22.5 min in Sweden.9
Addressing adherence is a major step forward towards improved patient outcomes
Usually, after a diagnosis, taking a medicine is the first step on the road to better health. But a large number of patients don’t take their medicine as prescribed. Adherence is all about the extent to which patients follow medical treatment and advice.10
of a treatment means that the patient has received the medicines prescribed by the doctor 11
of a treatment means that the patient has taken the medicine over the initially intentioned duration 11-13
with treatment means that the patient has taken the medicines as prescribed11-13
Adherence is a behavior
Majority of patients state “forgetting” as their main reason for non-adherence.15
However, recent studies show that providing reminders are only helpful if patients are motivated to take their medicines and comply with their treatment.16
Adherence is a repeated and ongoing health behavior. If patients are not adherent, they need something to help them change their behavior. Using theory-driven, evidence-based behavioral interventions can influence patient health.
Our unique approach to improving adherence represents a new world of educating healthcare professionals and empowering patients, driven by the intersection of behavioral science and technology.
From treating disease to treating patients
By collaborating with leading experts in the medical community, we are working together towards our common goal of improving people’s health by helping them adhere to their treatment.
