Adherence vs. Compliance

What's the Difference?

Adherence and compliance are two terms often used in healthcare to describe a patient's behavior towards following medical advice or treatment plans. Adherence refers to the extent to which a patient follows the recommended course of action, including taking medications as prescribed, attending appointments, and making necessary lifestyle changes. Compliance, on the other hand, specifically focuses on the patient's willingness to follow the instructions given by healthcare professionals. While adherence emphasizes the patient's active participation and responsibility in their own care, compliance implies a more passive role of simply obeying instructions. Both adherence and compliance are crucial for successful healthcare outcomes, as they ensure that patients receive the full benefits of their treatment plans.

Further Detail


When it comes to healthcare, two terms that are often used interchangeably are adherence and compliance. While they both refer to a patient's ability to follow medical advice, there are subtle differences between the two. Understanding these differences is crucial for healthcare professionals to provide effective care and support to their patients. In this article, we will explore the attributes of adherence and compliance, highlighting their unique characteristics and implications.


Adherence refers to a patient's willingness and ability to follow a prescribed treatment plan or medical advice. It emphasizes the collaborative nature of the patient-provider relationship, where the patient actively participates in decision-making and takes responsibility for their health. Adherence recognizes that patients have autonomy and personal preferences that should be considered when developing a treatment plan.

One of the key attributes of adherence is the patient's understanding of their condition and treatment. Patients who adhere to their treatment plans are often well-informed about their health, the rationale behind the prescribed interventions, and the potential benefits and risks. They actively seek information, ask questions, and engage in shared decision-making with their healthcare providers.

Another important aspect of adherence is the patient's motivation and belief in the effectiveness of the treatment. Patients who are adherent are more likely to have a positive attitude towards their treatment, believing that it will lead to improved health outcomes. They may also have a strong sense of self-efficacy, feeling confident in their ability to manage their condition and adhere to the recommended interventions.

Adherence is often associated with long-term behavior change. Patients who adhere to their treatment plans are committed to making sustainable lifestyle modifications, such as adopting a healthy diet, engaging in regular exercise, or quitting smoking. They understand that their actions have a direct impact on their health and are willing to make the necessary adjustments to achieve their treatment goals.

Lastly, adherence recognizes the importance of patient-provider communication and trust. Patients who adhere to their treatment plans have open and honest conversations with their healthcare providers. They feel comfortable discussing their concerns, sharing their experiences, and seeking clarification when needed. This collaborative relationship fosters trust, which is essential for effective healthcare delivery.


Compliance, on the other hand, refers to a patient's adherence to medical advice solely based on the authority of the healthcare provider. It implies a more passive role for the patient, where they simply follow instructions without necessarily understanding the rationale behind them. Compliance is often associated with a hierarchical patient-provider relationship, where the provider's expertise is unquestioned.

One of the key attributes of compliance is the patient's willingness to follow instructions without questioning or seeking additional information. Patients who comply with medical advice may not actively participate in decision-making or express their preferences. They may rely solely on the expertise of their healthcare provider and trust that the prescribed interventions will lead to positive outcomes.

Compliance is often driven by external factors, such as fear of negative consequences or the desire to please the healthcare provider. Patients who comply may feel obligated to follow the prescribed treatment plan due to social pressure or a sense of duty. They may prioritize the provider's expectations over their own personal preferences or values.

Unlike adherence, compliance may not necessarily involve long-term behavior change. Patients who comply may be more focused on short-term outcomes or immediate relief of symptoms. They may be less inclined to make sustainable lifestyle modifications or engage in self-management practices beyond the duration of the prescribed treatment.

Lastly, compliance may be associated with a more transactional patient-provider relationship, where communication is primarily one-way. Patients who comply may hesitate to ask questions or express concerns, fearing that it may disrupt the perceived authority of the healthcare provider. This lack of open communication can hinder the development of trust and limit the effectiveness of healthcare interventions.

Implications for Healthcare

Understanding the attributes of adherence and compliance has significant implications for healthcare professionals. By recognizing the importance of adherence, healthcare providers can foster a collaborative and patient-centered approach to care. They can encourage patients to actively participate in decision-making, provide them with the necessary information and resources, and support their autonomy in managing their health.

Healthcare professionals can also promote adherence by building strong patient-provider relationships based on trust and open communication. By creating a safe and non-judgmental environment, patients are more likely to express their concerns, ask questions, and share their experiences. This enables healthcare providers to tailor treatment plans to the individual needs and preferences of their patients, ultimately improving treatment outcomes.

On the other hand, healthcare professionals should be cautious about relying solely on compliance. While compliance may be appropriate in certain situations, such as emergency care or acute conditions, it may not be sufficient for long-term management of chronic diseases. By recognizing the limitations of compliance, healthcare providers can strive for a more patient-centered approach that promotes active engagement and sustainable behavior change.

Furthermore, healthcare professionals should be aware of the potential barriers to adherence and compliance. Factors such as limited health literacy, cultural beliefs, socioeconomic status, and access to healthcare services can significantly impact a patient's ability to adhere to their treatment plans. By addressing these barriers and providing appropriate support, healthcare providers can enhance patient outcomes and reduce healthcare disparities.

In conclusion, while adherence and compliance are often used interchangeably, they have distinct attributes and implications in healthcare. Adherence emphasizes patient autonomy, collaboration, and long-term behavior change, while compliance may involve a more passive role, external motivation, and short-term focus. By understanding these differences, healthcare professionals can provide patient-centered care that promotes active engagement, trust, and improved treatment outcomes.
