People with chronic conditions like diabetes, atrial fibrillation, hypothyroidism, and high blood pressure often struggle to take their medicines correctly. This study looked at whether adding nurse-led care coordination would help. The team studied over 8,000 high-need patients who were commercially insured. They wanted to see if this extra support made a real difference in how much of the time patients took their drugs.
results show that for most medicines, the extra care did not change the outcome. Patients taking metformin for diabetes or statins for heart health had similar adherence rates whether they got the nurse support or not. The same was true for direct oral anticoagulants used for blood thinning. Even when looking at continuous adherence, the groups performed the same.
There was one exception. People taking levothyroxine for thyroid problems were more likely to stay on track when they received the nurse-led support. This group showed a small but real improvement. However, the study did not report safety issues or side effects for any of the groups. The researchers used strict methods to compare the groups fairly.
This trial highlights the difficulty of improving medication habits for complex patients. While nurse-led care is a common strategy, this large national study suggests it does not automatically fix adherence for most common drugs. The findings are grounded in real data from a pragmatic trial run by a large national insurer.
