 Study Says New Approach to Postsurgical Monitoring After Surgery Could Keep Patients Out of ICUs
Anesthesiologists at Dartmouth-Hitchcock Medical Center (DHMC) in Lebanon, New Hampshire have implemented a simple yet enormously effective patient surveillance system that has proven to dramatically decrease the number of rescue calls and intensive care unit transfers in postsurgical patients, allowing doctors to intervene in more cases before a crisis situation develops.

Andreas H. Taenzer, M.D., F.A.A.P. and his colleagues published the results of their study in the February 2010 issue of Anesthesiology.

The group''s study is the first published report of such a surveillance monitoring system, which seeks to detect patient adverse events occurring in the general postoperative care setting when medical staff is immediately available to intervene, but is unaware of the deteriorating condition.

"Our primary finding is that early detection of patient deterioration in important areas such as oxygen saturation and heart rate led to fewer rescue events and a decreased need to escalate care," said Dr. Taenzer.

About the Study
In the study, orthopedic patients were monitored by measure-through motion and low perfusion pulse oximetry finger probes (which measure oxygen in the blood) connected to a computer that notified nurses when physiological abnormalities were detected. These abnormalities are often the first sign that a more serious situation may be developing.

After collecting data for nearly two years, Dr. Taenzer found that emergency rescue calls dropped from 3.4 to 1.2 per 1,000 patient discharges, and intensive care unit (ICU) transfers declined from 5.6 to 2.9 per 1,000 patient days.

"With an average length of stay of just over five days for patients transferred to the ICU, this saves our institution 135 ICU days per year in our 36-bed unit alone," said Dr. Taenzer. Statistically, this worked out to a 65-percent reduction in rescue events and a 48-percent reduction in transfers to the ICU.

Ninety-eight percent of patients agreed to wear the oximetry probe and to be monitored. According to Dr. Taenzer, the nursing staff involved in the study commented that the surveillance system helped to increase their knowledge about the status of the patients under their care.

Potential Broader Reach of Care for Monitoring System
Although the study was limited to mostly elderly patients who had undergone orthopedic surgery, Dr. Taenzer sees a much broader potential for the patient surveillance systems.

"Unrecognized adverse events affect patients in academic medical center settings as well as those in small community hospitals, and they affect patients who''ve had surgery as well as those who have not," he said. "Continuous patient monitoring represents a new area of research in patient safety, and we are optimistic that any patient admitted to a hospital may benefit from this kind of monitor."

New for 2010 in Anesthesiology
As part of a mission to promote new discoveries and influence clinical practice, the January issue of Anesthesiology marks the debut of a newly designated "Education" section. This section is designed to highlight clinical material, making it more accessible and relevant for implementation in everyday clinical practice.

Founded in 1905, the American Society of Anesthesiologists is an educational, research and scientific association with 43,000 members organized to raise and maintain the standards of the medical practice of anesthesiology and improve the care of the patient.
