I often though that increasing patient adherence lived in my ability to educate and build patient understanding. The truth is that it starts in understanding the values and priorities of the patient. Questions first. 

If you’ve ever felt frustrated about patients not following treatment plans – or guilty about not following one yourself – you’re not alone. But here’s the thing: we’ve been thinking about adherence all wrong.

The Truth About Patient Adherence

Let’s start with what adherence actually means. While many think it’s just “following doctor’s orders,” the World Health Organization defines it as “the degree to which a person’s behavior corresponds with agreed recommendations.” That word “agreed” changes everything.

To agree, means that the patient understands how your recommendations align with what matters most to them. As a provider, we have an obligation to explore this first, or else our recommendations are nothing more than a shot in the dark, and hoping that the patient will just buy in to “what we know is best for them.” 

The Real Numbers That Should Worry Us

The statistics around treatment adherence are sobering:

  • Only 50% of medications for chronic conditions are taken as prescribed
  • Healthcare providers typically overestimate patient adherence by 50-75%
  • Poor adherence leads to approximately 125,000 deaths annually

Why We Don’t Follow Through (Even When We Want To)

Research shows that non-adherence typically falls into two categories:

1. Intentional Non-Adherence (“Won’t”)

  • Belief the treatment isn’t necessary
  • Fear of side effects
  • Cost concerns
  • Complex treatment regimens

2. Unintentional Non-Adherence (“Can’t”)

  • Forgetfulness
  • Misunderstanding instructions
  • Physical limitations
  • Life circumstances

Bridging The Adherence Gap

The solution isn’t more strict instructions – it’s better collaboration. Here’s what works:

For Healthcare Providers:

  • Use shared decision-making
  • Implement “teach-back” methods
  • Create realistic, personalized plans
  • Schedule regular check-ins

For Patients:

  • Be honest about barriers
  • Ask questions until you understand
  • Suggest modifications that fit your life
  • Use technology for reminders

The Technology Factor

Modern tools are changing the adherence game:

  • Smart pill bottles
  • Mobile health apps
  • Automated reminder systems
  • Digital tracking tools

Making It Stick: Real-World Solutions

Success comes from practical strategies that work in real life:

  • Link new habits to existing routines
  • Use visual cues in your environment
  • Create accountability partnerships
  • Track progress visually

The Path Forward

Whether you’re a provider or patient, improving adherence starts with understanding it’s a two-way street. Visit our Patient Motivator Questionnaire to identify your adherence style and get personalized strategies.

Patient compliance misses the mark. It shows show up rates, but not patient carryover or involvement in the care plan, where the true long term impact lives.
