The Next Frontier in Patient Engagement: How AI is Redefining Adherence and Support

Introduction

The pharmaceutical industry is undergoing a quiet revolution. Gone are the days of generic reminders and one-size-fits-all patient support. Yet patient non-adherence remains one of the pharmaceutical industry’s most stubborn challenges, costing over $500 billion annually and contributing to 125,000 preventable deaths​.

Traditional outreach efforts—pamphlets, reminders, call centers—have struggled to create sustainable engagement. But artificial intelligence (AI) is quietly transforming that story.

As detailed in our whitepaper on AI-driven patient engagement, the future lies in predictive, personalized, and always-on support ecosystems that are tailored to individual patient journeys. This evolution isn’t just about technology; it’s about creating meaningful partnerships with patients to improve health outcomes.

Let’s explore how AI is redefining adherence and support through precision, empathy, and continuous learning.

Adherence from Chance to Choice

Traditional adherence programs often rely on blanket reminders—postcards, emails, or automated calls—that treat every patient the same. AI flips this script by predicting who needs support, when, and how. Instead of reacting to missed doses, AI enables pharma brands to predict non-adherence before it happens by analyzing refill patterns, app interactions, wearable data, and more. As it moves on from generic outreach to tailored interventions that address individual patient risks, patients with chronic conditions (e.g., diabetes, hypertension), and ecosystem partners like pharmacists and care teams can

• Use predictive analytics to flag at-risk patients.
• Personalize intervention types (texts, calls, educational content).

With advanced machine learning models that analyze historical data like prescription refills, EHRs, and social determinants to forecast adherence risks, adherence rates which can lead to a reduction in hospitalizations, thereby improving patient satisfaction scores.

This precision ensures resources are allocated to patients who need them most, avoiding alert fatigue and maximizing impact.

This precision ensures resources are allocated to patients who need them most, avoiding alert fatigue and maximizing impact.

For example, Walgreens used AI models to personalize intervention strategies per patient, determining whether a text, a call, or a digital prompt would most likely influence adherence​

Impact achieved:

• +9.7% adherence improvement for statins
• +8.6% for diabetes meds
• +5.5% for hypertension drugs

Micro-segmentation like this is making patient engagement more precise with prediction-driven engagements

AI as a Virtual Companion with Always-On support

Beyond predictive models, conversational AI like chatbots plays a critical role. It isn’t just sending reminders; it’s becoming a trusted ally in patients’ daily lives.

GSK’s pilot of an AI-driven respiratory chatbot showed how virtual coaches could assist asthma and COPD patients with inhaler techniques, trigger management, and side-effect advice​. The chatbot uses natural language processing (NLP) to answer questions and unlike rule-based bots, modern NLP models detect patient sentiment and respond empathetically.

For example, a patient messaging at 2 A.M. about side effects might receive:

“I’m sorry you’re experiencing this. Let’s review your inhaler steps together—would that help?”

Chatbots handle routine queries (e.g., dosing instructions), freeing clinicians to focus on complex cases. If a patient mentions severe symptoms, the bot escalates the conversation to a human.

Patients engaged longer and showed higher satisfaction due to:

• 24/7 availability
• Judgment-free education loops
• Fast escalation to human support when needed

This hybrid model ensures patients feel supported and frees healthcare staff for high-value tasks while maintaining constant patient touchpoints.

Reinforcement Learning with the AI Advantage

Modern engagement platforms now use reinforcement learning to constantly refine their strategies, and with AI’s true power, which lies in its ability to learn and adapt. With the continuous optimization based on real-world feedback, data scientists and patient support teams

• Optimize messaging timing, channel, and content
• Test and iterate on interventions
• Prioritize high-risk non-adherent patients
• Personalize outreach cadence over routine care.
  

Reinforcement learning algorithms analyze patient responses to adjust tactics. For example, if a patient ignores texts but responds to calls, the AI prioritizes calls for future outreach. This feedback loop improves the system’s effectiveness over time, making each touchpoint smarter than the last​.

Walgreens’ program “micro-segments” patients into thousands of unique profiles, ensuring no two engagement plans are alike.

Why Infrastructure Matters

Behind every successful AI initiative is a robust digital backbone, and to power dynamic patient engagement, pharma firms must invest in:

• Integrating EHRs, pharmacy systems, and wearables for a 360-degree patient view.
• Cloud-based analytics to ensure real-time data flow between AI tools and clinical workflows.
• FHIR-standard interoperability with clinical systems.

Cloud platforms like AWS, Google Cloud, and Azure enable scalable data aggregation.
For example, Novartis’ AI lab with Microsoft ingests real-world data to predict therapy drop-offs, triggering early interventions, while legacy EHR integration requires APIs and FHIR standards, but the payoff — “seamless care coordination”—is worth it.

Strategic AI Drives Human-Centric Outcomes
The future of patient engagement isn’t just smarter algorithms—it’s smarter collaboration. Success hinges on aligning AI with patient needs, clinician workflows, and ethical guardrails.
At Altimetrik, we believe AI should:

‍

1. Augment human touchpoints.
2. Prioritize transparency to build patient trust.
3. Measure impact through health outcomes, not just efficiency gains.

As detailed in our whitepaper on AI-driven patient engagement, it emphasizes that closing the loop between AI insights and clinical workflows is key to truly actionable engagement.

When done right, AI doesn’t replace human support—it amplifies it at scale. AI-driven patient engagement is a digital product challenge, not just a data science one.

We have partnered with leading life sciences companies to:

• Integrate predictive models with real-world patient journeys
• Build omnichannel orchestration engines
• Create compliant, scalable, insight-driven engagement systems

Patient engagement is no longer a “nice-to-have. It’s a strategic lever for improving outcomes, boosting loyalty, and driving growth, and AI isn’t the future of this transformation. It’s the present.
