Smartphone-based system may improve health of patients with chronic diseases

May 12, 2016

A new study shows how mobile technology can allow patients to work collaboratively with clinicians to improve their health. The research, which appears in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN), may signal a paradigm shift in the model of healthcare delivery.

Self-management has been advocated as a way for to cope with the challenges of living with a complex chronic disease and gain some measure of control over their own health. It's important that it be thoughtfully integrated into the overall goals of care, however.

With this in mind, a team led by Alexander Logan, MD FRCP(C), Stephanie Ong, BScPhm, MSc, and Vanita Jassal, MD FRCP(C) (University of Toronto, University Health Network, and Mount Sinai Hospital) recruited 47 patients with into a 6-month study on the potential of a smartphone-based system that enabled patients to monitor their blood pressure, assess their symptoms, maintain an accurate medication list, and view key laboratory test results. Patients, of whom 60% had never used a smartphone, received real-time personalized feedback, and providers received alerts when treatment thresholds were crossed or critical changes occurred.

Among the major findings:

  • Average in-home blood pressure readings dropped significantly over the 6 months of the study (systolic, -3.4 mmHg; diastolic, -2.1 mmHg).
  • 27% of patients with normal clinic blood pressure readings had newly identified masked hypertension (normal clinic blood pressure but elevated blood pressure outside of the clinic).
  • 127 medication discrepancies were identified; 59% were a medication error that required an intervention to prevent harm.
  • At the end of the study, patients reported feeling more confident and in control of their condition, and clinicians perceived patients to be better informed and more engaged.

"We were able to help patients monitor , symptoms, and medications by enhancing and bolstering patient autonomy and confidence through immediate messages giving customized, patient-specific feedback," said Dr. Logan. "Unlike other mobile applications, we believe this is the only mobile application for outpatient use, which offers patient-driven care in a supportive, customized environment."

Dr. Logan stressed that the findings require further validation through comparison with a control group and over a longer duration of time. It will be important to assess whether the application has an impact on patients' health outcomes and the quality of care they receive.

In an accompanying editorial, Tejas Desai, MD (East Carolina University), Jerry Yee, MD, and Sandeep Soman, MD (Henry Ford Hospital) noted that the researchers' results provide a strong rationale for a randomized, controlled trial. "Although their investigation is a proof-of-principle study, their results highlight broader considerations when integrating smartphone technology with healthcare," they wrote.
