Mobile Phone App Helps Patients Take Medication More Consistently: Study
George Washington University researchers, chip maker Qualcomm, wireless carrier Cricket and app developer Vocel presented results of a study showing how a mobile phone application helped patients take medication more consistently.
WASHINGTON, D.C.-Patients with high blood pressure did a better job of taking prescribed medication through the use of a mobile phone application that reminded them when to take their pills, according to the results of a recent medication adherence study conducted by George Washington University here.
The study results were discussed at a Feb. 9 conference hosted by GWU and included several parties that supported it, including mobile chip manufacturer Qualcomm, mobile health application developer Vocel, nonprofit group One Economy and wireless operator Cricket Communications.
GWU's research examined how well mobile technology helped hypertensive patients in communities underserved by medical professionals stay on their medication regimes. The participants in the GWU conference also addressed the potential for improvements in mobile health technology.
The study involved the use of Vocel's Pill Phone, which is a mobile phone application that allows patients to receive audio or visual medication reminders; track records of dosage; and access content from "The Pill Book" on side effects and interactions. It was the first mobile medication management app to receive FDA approval, according to Vocel. The study found participants to be "generally satisfied" with medication reminders from the Pill Phone app.
In addition, the survey revealed high acceptance and prolonged use of Pill Phone. Medication use rates rose moderately from 75 percent to 82 percent while patients used the app, but dropped when participants stopped using Pill Phone.
Although researchers expected subjects to be taking one or two pills per day, patients' intake averaged up to 10 a day and ranged from three to 16.
"We designed the UI around most people on one or two, but people are on about eight a day," Vocel CEO Carl Washburn said during a panel discussion.
Poor adherence to medication schedules leads to inadequate blood pressure control for more than two-thirds of patients, noted Dr. Richard Katz, director of cardiology at the GWU Medical Center, which coordinated the research.
In fact, poor medication adherence costs the health care industry $100 billion a year in avoidable hospitalizations, according to a Harvard University study.
One Economy, a firm that uses technology to help underserved communities, came up with the idea for the study and approached GWU to consider the project, Clark D. Ritchie, the company's CTO, told eWEEK in an interview with the study organizers at GWU.
The university then consulted with Qualcomm's Wireless Reach program, which funded the study. Wireless Reach provides funding, education and access to programs that connect underserved communities to wireless technology.
For the seven-month study, wireless operator Cricket supplied 50 low-income Medicaid patients from the university's clinics with 3G EV-DO handsets running the Pill Phone app. The goal was to test how well subjects kept to their medication routine. Meanwhile, doctors monitored the participants' progress using a secure Web site.
The average age for participants was 53 with a range of 33-78. In addition, 96 percent of the Medicaid participants from GWU's D.C. clinics were African-American, and only 17 percent of the sample had finished college.
"We were able to take a population with a lot of challenges, and they liked the intervention and they were able to use it to improve their adherence to medication," Erica M. Whinston, Qualcomm's senior manager for government affairs, Wireless Reach, told eWEEK.
