Total Knee Replacement Quality Measures
Wrong-patient, wrong-procedure, or wrong-site surgeries
are uncommon, but they can be avoided altogether by following careful procedures
prior to surgery. The following procedures cover broad areas of concern in
preventing surgical mishaps; however, there are additional safeguards used
by surgical teams that are not listed here.
The first procedure involves review
of relevant medical records prior to surgery. These records may contain information
that will prevent the need for additional tests, saving time and money. They
may also provide vital facts about your health history that your surgical team
needs to know.
Secondly, according to the Joint
Commission on Accreditation of Health Care Organization's (JCAHO) Universal
Protocol for Prevention of Wrong Site, Wrong Procedure, Wrong Person Surgery,
it is recommended that the operating surgeon mark the operative site using a
signature or other approved mark.
Extra care should be taken with moist areas that can smear
onto another site such as the inside of the thigh, according to a report in
Anesthesia and Analgesia (January, 2005; 100 (1): 300). Smearing can occur
where marked skin touches unmarked skin and the unintended marks may cause
confusion about the correct site for surgery.
Lastly, just prior to surgery
a final review is performed to ensure that the right patient is having the
right procedure on the right body part, with all necessary patient information
available. The armband may be checked several times during this process to
verify that the team has the correct patient.
An opportunity for speaking up
is provided during this final review; it is a built-in pause (time-out) to
provide an opportunity for anyone on the surgical team to speak up about anything
related to the procedure or patient that is questionable.
At St. Mary's Hospital Medical Center, the following steps are taken to ensure correct-patient, correct-procedure and correct-site for knee surgery:
- pre-admission collection and review of medical records
- pre-operative verification checklist used (includes multiple clinical check points such as laboratory test results and arm band check)
- marking of site intended for surgical repair
- operative team review of procedure details with built-in pause (time-out)
- armband verification
