Chances are, when patients check out of a hospital for home or another health care facility, they will end up back in the hospital within a month if they have not worked out the details and logistics for ongoing care. Too often such planning falls by the wayside, resulting in frequent hospital readmissions.
For the federal government, the cost to Medicare alone totals more than $17 billion each year for return trips to the hospital, to say nothing of the difficulties for the patients themselves. (pdf) The Affordable Care Act’s (ACA) proposed cure for this condition is for hospitals, healthcare workers and patients to make greater use of technologies that monitor health remotely, ensuring patients receive proper medical care to avoid additional hospital visits.
The Obama administration introduced the ACA in 2010 to move health care away from a fee-for-service model to one that promotes preventative care and overall wellness. Beginning this October the ACA will reinforce this approach by penalizing hospitals with chronic readmission problems by cutting Medicare reimbursement payments to those facilities. This policy initially targets patients suffering from three health conditions—heart failure, pneumonia and heart attack—but penalties will apply to additional conditions beginning in 2015.
About one in five Medicare patients return to the hospital within a month after discharge. Although some hospital readmissions are unavoidable—the odds are higher for the elderly and those with chronic conditions—many result from the lack of transitional care and long-term support, says Mary Naylor, a professor at the University of Pennsylvania School of Nursing who has researched the most common reasons for rehospitalization. Among frail, older adults these include stroke, hip fracture, sepsis and urinary tract infection.
Technologies most likely to help hospitals lower readmission rates and limit penalties include so-called “telehealth” systems that connect patients with physicians, nurses or other care managers after checkout, microchipped pills that indicate whether patients take their medicine as prescribed and software that improves the management of electronic health records (EHRs).
Telehealth has matured beyond the ability to simply gather and transmit patient information over the Internet and wireless networks. Newer technologies include touch-screen devices and software that guide ongoing care. Bosch Healthcare’s wireless T400 Telehealth System for discharged patients, for example, addresses dozens of medical conditions, including chronic obstructive pulmonary disease, congestive heart failure and diabetes. Patients enter their vital signs into the T400 daily, and the device transmits that data to their health care provider for review and response.
Other remote health monitoring systems have patients wear sensors that wirelessly collect, store, analyze and transmit health-related data. One of several approaches is the Wearable Wellness System from Italy’s Smartex, essentially an undershirt with embedded sensors and a processor that can monitor heart and respiration rates. Although not as fashionable, the Metria wearable sensor, from Vancive Medical Technologies, a medical division of Avery Dennison, can be adhesively bound to the body to measure heart rate, respiration, sleep duration and activity levels.
One person who sees a great need for use of telehealth technology in patients with chronic conditions is Richard Della Penna, a former physician with Kaiser Permanente and chief medical officer at Independa, a company that sells software and services designed specifically to help the elderly live independently. “If a health device is able to capture data that predicts when a person with, say, heart failure is starting a readmission trajectory, and someone quickly responds appropriately to the incoming data, only then may readmission rates be impacted," he says.
But some warn that sensors and the like, despite their potential for good, could backfire by creating more work for physicians and other health care workers. “A big challenge is addressing the huge amount of data that is obtained through monitoring,” says Mary Rodgers, professor and chair of the Department of Physical Therapy and Rehabilitation Science at the University of Maryland School of Medicine. “It has to be analyzed, points of concern have to be
