Attention Clinical Staff
Coumadin Therapy – Surveyors are focusing on anticoagulant therapy more closely due to recent
incidents of resident harm and immediate jeopardy related to Coumadin therapy. Although not meant
to be all inclusive, here are some of the key issues to take into account when reviewing your policies and
procedures:
•
Physician: Communicate this concern to your Medical Director and attending physician staff.
Ask for their input related to their practice and facility policy. Request their guidance on
providing education for the nursing staff.
•
INRs: It is generally recommended that all residents on Coumadin therapy have INR testing. The
frequency of testing depends on the individual resident (i.e. residents who are going through
frequent dose changes.) Therapeutic INR ranges are usually between 2.0 and 3.5. The
appropriate “number” within this range for a particular individual would depend on what the
anticoagulation was prescribed for. The higher range of 3.5 is used to prevent clot formation as
with residents who have had heart valve replacement whereas the lower range of 2‐3.0 may be
used to control atrial fibrillation.
•
Tracking protocol: Use a tracking sheet for each resident on anticoagulation therapy as an easy
method for all practitioners to readily access information. In addition to drug dose and INR
levels, the sheet should include an area to record communication with the physician related to
the INR level and any additional orders received. See sample form attached. Insure appropriate
policies and documentation related to the reporting of “panic” levels between lab and facility
and between facility and physician.
•
Coumadin and antibiotics: Residents beginning antibiotic therapy, particularly quinolones
which effect INR levels, should be monitored during their course of antibiotic treatment.
•
Dietary: Vitamin K reverses the anticoagulant effect of Coumadin. Many green vegetables such
as broccoli, kale, spinach, peas, and Brussels sprouts should be avoided or eaten in smaller
amounts less frequently. The nutritional supplement Boost and green tea may also have large
amounts of Vitamin K. For a complete list of Vitamin K levels in foods, go to
•
Drug‐Drug Interactions: Explore with the pharmacy ways to increase the level of “alert” to
nurses administering Coumadin when there is a possibility of drug‐drug interaction. Include
alerts for over‐the‐counter supplements which can also react with Coumadin, such as St. John’s
wort, garlic, ginkgo, ginseng and cranberry extract to name a few.
•
Monitoring: All staff, including CNAs, should be aware of those residents on anticoagulation
therapy and instructed to report any increase of or large bruising, nose bleeds and/or dark or
tarry stools immediately as this may be a sign of an abnormal INR. Nurse should report same to
physician.
•
Falls/Head injury: Residents on anticoagulation therapy are at increased risk for subdural
hematoma should they suffer a fall with head injury. Monitor for mental status and conduct
neurological checks on residents who have a head injury, a witnessed fall with head injury and
also for those whose fall was unwitnessed and you cannot determine whether or not they struck
their head.
