Adherence Improves With 90-Day Medication Supply
Medication adherence increased in patients who received a 90-day supply compared with those who received a 30-day supply, according to a recent presentation at the Academy of Managed Care Pharmacy’s Annual Meeting.
Medication adherence increased in patients who received a 90-day supply compared with those who received a 30-day supply, according to a recent presentation at the Academy of Managed Care Pharmacy’s Annual Meeting.
Hermes and colleagues1 of BlueCross BlueShield of Illinois compared adherence data from patients treated with long-term medications from 1 of 3 classes: cholesterol-lowering, hypertension, and diabetes drugs. Members of BlueCross BlueShield of Illinois were identified in a claims database. After 540 days of follow-up, patients with a 90-day supply of medication were 7.1% to 9.9% more likely to adhere to treatment (Figure). Nonadherence was 40% less likely to occur in those patients who received 90-day supplies of medication.
To improve rates of adherence, organizations are initiating programs to encourage patients to receive 90-day prescriptions.
In September, Walgreens announced a broad initiative to increase the number of 90-day prescriptions it dispenses. According to a statement, the company will work with patients, physicians, insurers, employers, and MCOs to convert traditional 30-day long-term–care prescriptions into 90-day prescriptions.
“For many chronic-care conditions, Walgreens has seen an approximate 15% increase in adherence to medications for patients receiving a 90-day retail prescription versus those receiving a 30-day supply,” said Greg Wasson, Walgreens president and CEO.2
Wasson noted that Walgreens has already seen success with 90-day supplies of medications in targeted Walgreens programs. “Taking into account that each 90-day prescription fill equals 3 times the volume of a 30-day fill, more than 24% of our Medicare Part D beneficiaries’ prescription volume and 47% of our Prescription Savings Club members’ prescription volume are filled as 90-day supplies at our retail pharmacies. Based on that experience, we are confident this program will be extremely well received.”
