Taking Telemetry Out of the Hospital Improves Outcomes, Reduces Alarm Fatigue

Posted on by Kurt Jensen

A new study suggests the use of an off-site cardiac telemetry central monitoring unit (CMU) could improve telemetry alarms for non-intensive care unit patients and reduce the number of monitored patients—without increasing cardiopulmonary arrest events.

The study, published August 2 in the Journal of the American Medical Association, studied all non-intensive care unit patients at Cleveland Clinic and three other regional hospitals over a period of thirteen months. An off-site CMU applied "standardized cardiac telemetry" for 99,048 patients during that time.

The Data

Among the study's population, emergency response team (ERT) activation occurred for 3,243 patients. 979 of those patients had rhythm or rate changes occurring up to one hour prior to the ERT activation. The CMU detected and provided accurate notification for 772—or 79 percent—of those events, according to the study's abstract.

For 105 patients, the CMU provided "discretionary direct ERT notification" for events requiring urgent clinical intervention, reads the abstract. Slightly more than one in four of those patients went on to experience cardiopulmonary arrest events—27 patients, or 26 percent. Return to circulation was achieved in 25 of those patients, or 93 percent.

Telemetry standardization also reduced the number of patients monitored by 15.5 percent per week through eliminating low-risk patients.

How the Central Monitoring Unit Works

The study's model used one monitoring technician to provide continuous cardiac monitoring for up to 48 patients, providing blood pressure, pulse oximetry, and respiratory rate notifications on request, according to the JAMA media release. A lead technician also provided oversight and supervision for real-time rhythm interpretation.

Routine Cardiac Catheterization Expanding to Saturdays?

Posted on by Kurt Jensen

Expanding availability of elective, non-emergent cardiac catheterization services to Saturdays might significantly reduce length of stay, with no effect on clinical quality reports a recent economic impact study.

The study, published online in the American Journal of Managed Care found that reduced length of stay did not result in total cost savings, however.

In January 2009, Mayo Clinic Rochester expanded cardiac catheterization service availability (CSA) to Saturdays with the "goal of timely access with improved efficiency of care," write the authors.

Despite succeeding in greatly reducing length of stay—a statistically significant, adjusted average of 1.73 days—total costs of care were similar prior to CSA expansion.

A new cardiac imaging paradigm for acute chest pain?

Posted on by Kurt Jensen

In the "high-sensitivity cardiac troponin era," will the role of cardiac imaging in the ED change?

As high-sensitivity cardiac troponin (hs-cTn) assays become more and more common, cardiac imaging becomes less necessary for ruling out acute myocardial infarction (AMI) in ED patients with acute chest pain, but might be useful to prevent unnecessary or aggressive treatments write experts in July's volume of the American Heart Journal.

ACVP blog has covered the groundbreaking research on the high-sensitivity cardiac troponin tests since early last year, when we reported a new strategy that could rule out acute myocardial infarction within one hour, and rule it in with 75 percent accuracy. In June, two studies publishes in JAMA Cardiology lent further support to one-hour algorithms.

The speed and safe, accurate "rule out" of acute myocardial infarction through these cardiac biomarker tests "challenges [the] need" for noninvasive imaging prior to patient discharge when troponin values are normal, write the authors of the American Heart Journal article.

Has ACVP solved a critical issue facing European medical conferences?

Posted on by Sean McElgunn

Thanks to the recent adoption of a new code of ethical conduct by MedTech Europe, a group of industry associations doing business in Europe, the future of European cardiology conferences may soon be in jeopardy.

The reason? More barriers to attendance.

It’s not that these conferences suffer from a lack of interested medical professionals. It’s just that, while many MDs would very much like to attend, registering for a cardiology conference in Europe is not cheap—on the order of thousands of dollars per event.

Everybody, the attendees, the presenters, with the exception of a very limited number of senior professors, has to pay, and it is understood that the physicians will attend more than a few over the course of a year.

And, in the time honored tradition of using off-site attractions as a lure for good registration numbers, the meetings are held in “not cheap” locations across the Continent, further ballooning the cost of attendance.
