Medication adherence means taking medications exactly as the doctor says. In the United States, many patients do not follow their medication plans. According to the Centers for Disease Control and Prevention (CDC), about 20% of new prescriptions are never filled. Nearly half of the medications that patients take are used incorrectly. This causes poorer health, more hospital visits, and higher risk of serious illness or death. It also costs a lot of money, with nonadherence contributing $100 to $300 billion each year in healthcare costs.
There are different reasons why patients do not take their medications properly. Some forget to take their pills or find their treatment plans hard to follow. Cost can be a problem, like paying copays. Sometimes patients choose not to take medicines because they worry about side effects or do not believe the medicine will help. Problems with doctors and nurses, like poor communication or lack of teamwork, also affect medication use. Other difficulties come from the healthcare system, such as trouble getting prescriptions or unclear instructions.
Team-based care means different healthcare workers work together with patients and doctors to improve treatment. This way of working has helped people with chronic illnesses do better, especially with taking medicines and managing their health.
A study that looked at 54 different projects found that team-based care helped lower blood pressure. Systolic blood pressure went down by almost 6 mm Hg, and diastolic pressure dropped by over 3 mm Hg. For patients with diabetes, blood sugar control improved by 0.38 percentage points. These changes might seem small, but they are important and better than when healthcare workers act alone.
Teamwork works well because tasks are shared. Pharmacists check medicines and teach patients. Nurses give advice on healthy living. Primary care providers organize the care. Projects with four to five different types of team members had better results in controlling blood pressure.
However, many teams do not have clear steps for making decisions together. Sometimes roles are not clearly shared, and leadership is missing. Fixing these issues could make the teamwork even better.
The CDC reports that patients in team-based programs take their medicines more regularly. For example, when pharmacists were part of community programs, medicine adherence rose from 74% to 89% one year after patients left the hospital. Pharmacists help by explaining drug schedules, finding problems, and working with doctors to improve treatment.
Lowering money barriers also helps. Studies show that reducing or removing copays for medicines increased adherence by 3 or 4%. This means helping with costs is important for better care.
Patient education that fits their culture and reading ability also works well. When information is simple and matches patients’ backgrounds, they understand their treatments better and stick to them.
High blood pressure affects many Americans and can cause heart disease and stroke. The Community Preventive Services Task Force (CPSTF) suggests team-based care to help control blood pressure, especially in racial and ethnic groups with greater health problems.
In this model, teams manage medicines, follow up with patients, support medication use, and teach healthy habits. Pharmacists play a key role by having agreements that let them adjust medications quickly, which helps address patient needs faster.
Patients also check their blood pressure at home, called self-measured blood pressure (SMBP) monitoring. Sharing these numbers with the care team helps doctors make better choices. Patients become more involved. This teamwork leads to better blood pressure control, fewer hospital visits, and lower healthcare costs.
Uncontrolled blood pressure costs the U.S. an estimated $131 to $198 billion each year. Team-based care saves money by preventing problems and lowering the need for expensive treatments.
Health information technology (HIT) helps support team-based care. Tools like electronic health records (EHR), e-prescribing, telehealth, and digital apps improve communication among healthcare workers. Research shows e-prescribing raises the rate of patients filling new prescriptions by about 10% compared to paper prescriptions.
Artificial Intelligence (AI) is becoming useful in improving medication use and making healthcare work smoother. Some companies, like Simbo AI, use AI to handle phone calls and help with patient communication. These AI systems remind patients about taking medicines and refilling them. They can spot missed doses and analyze data to find problems. This helps healthcare teams act early before serious issues happen.
Using AI also reduces repetitive work for staff. Automated calls and messages free up time for healthcare workers to focus on patients. AI can also reach out to patients who need extra help, checking for barriers like cost, language, or mental health challenges.
Data from devices patients use at home, like blood pressure or glucose monitors, can link to EHR systems. AI can study this data to find patterns, alert doctors to problems, and help plan care. For example, a medical group improved blood pressure control from 68% to 79% in three years by combining home monitoring with EHR tracking.
Technology and AI increase the ability of team-based care to serve patients better and more efficiently. This leads to better medicine use and health outcomes without using too many resources.
Coordination Framework: Define clear roles for each team member and create strong communication channels. Confusing roles or mixed messages can weaken teamwork.
Technology Integration: Use systems that connect EHRs, pharmacy data, and patient devices. Support for e-prescribing, automated reminders, and real-time data sharing is important.
Staff Training: Train staff on using AI and digital tools. Knowing the technology well helps its use and lowers mistakes.
Patient Engagement: Use AI-driven communication to give reminders, education, and access to care. Make sure the materials are easy to understand and respect the community’s culture.
Financial Considerations: Find ways to lower patient copayments and costs, since this helps improve medication use.
Quality Metrics: Regularly check clinical results with standard measures. Tracking data helps find problems and guide where to spend resources.
Sustainability: Build systems that allow ongoing monitoring of medication use and health outcomes. Long-term programs need constant review and changes as needed.
Using these steps, healthcare groups can better manage chronic diseases, leading to healthier patients and less unnecessary spending on healthcare.
Team-based care is becoming a practical way to manage chronic illnesses in the United States. With pharmacists, patient education, financial support, and health technology, medication adherence and health outcomes improve. Adding AI-driven workflow automation makes these models more efficient and able to serve more patients. Healthcare leaders who want better results and cost control should think about using team-based care with the latest technology for managing chronic diseases.
Medication adherence improves clinical outcomes and reduces mortality in chronic disease management. Nonadherence leads to higher hospital admissions, worse health outcomes, increased morbidity and mortality, and higher healthcare costs, estimating $100–$300 billion annually in the U.S.
Medication nonadherence is influenced by patient factors (forgetfulness, cost, beliefs), provider factors (communication barriers, complex regimens), and healthcare system factors (access issues, medication costs, unclear instructions, cultural materials availability).
Healthcare AI agents can monitor medication schedules, send reminders for doses and refills, detect missed doses in near real-time, analyze prescription data to identify adherence gaps, and facilitate personalized provider-patient communication.
Electronic pillboxes, blister packs combined with electronic reminders, e-prescribing systems that track unfilled prescriptions, and home-monitoring devices integrated with electronic health records have all improved adherence rates.
Team-based care including pharmacists for medication reconciliation, education, and collaborative care with providers has been shown to raise adherence rates significantly (e.g., from 74% to 89% at 12 months post-discharge), enhancing patient comfort and engagement.
Reducing or eliminating copayments raises adherence rates, as evidenced by a 3-4% increase in medication adherence among employees whose copays were lowered, demonstrating economic barriers as critical adherence deterrents.
Low health literacy, common among elderly, minorities, and low-income groups, impairs a patient’s ability to understand medication regimens, leading to nonadherence. Tailored, culturally appropriate education can improve adherence outcomes.
Sustaining medication adherence is difficult due to varying intervention effectiveness over time and lack of standardized methods to measure adherence consistently, limiting long-term evaluation and comparability across studies.
Integrating home monitoring data (e.g., blood pressure readings) with electronic health records enables providers to assess medication effectiveness, adjust treatments promptly, and engage patients with visual health progress, promoting adherence.
Strategies included patient education, culturally appropriate materials, cost-effective medication selection, simplifying regimens, side effect monitoring, empowering home blood pressure monitoring integrated into EHRs, and adherence monitoring via pharmacy claims and provider reviews.
