OMIC Risk Manager
PURPOSE OF RISK MANAGEMENT RECOMMENDATIONS
OMIC regularly analyzes its claims experience to determine loss prevention measures that our insured ophthalmologists can take to reduce the likelihood of professional liability lawsuits. OMIC policyholders are not required to implement these risk management recommendations. Rather, physicians should use their professional judgment in determining the applicability of a given recommendation to their particular patients and practice situation. These loss prevention documents may refer to clinical care guidelines such as the American Academy of Ophthalmology’s Preferred Practice Patterns
, peer-reviewed articles, or to federal or state laws and regulations. However, our risk management recommendations do not constitute the standard of care nor do they provide legal advice. If legal advice is desired or needed, an attorney should be consulted. Information contained here is not intended to be a modification of the terms and conditions of the OMIC professional and limited office premises liability insurance policy. Please refer to the OMIC policy for these terms and conditions.
Steroids and their effect on the eye have been studied for nearly fifty years. Some steroids are specifically approved by the Food and Drug Administration (FDA) for use in the eye. This list now includes triamcinolone acetonide (TA) injectable suspension, marketed as TriesenceTM (Alcon, Ft. Worth, TX) or TrivarisTM (Allergan, Riverside, CA). The indications noted in the approval are limited, however, to sympathetic ophthalmia, temporal arteritis, uveitis, and ocular inflammatory conditions unresponsive to topical corticosteroids. As a result, ophthalmic use of TA will still largely be “off-label.” Moreover, now that an FDA-approved form of TA is available, some ophthalmologists have contacted OMIC to inquire about the medicolegal consequences of continued “off-label” use of Kenalog.TM OMIC responded to similar queries about AvastinTM when LucentisTM was approved for age-related macular degeneration. OMIC’s Legal/Risk Management Department recognizes that “off-label” use of approved medications is a legal and necessary part of the practice of medicine. In the event of a lawsuit, ophthalmologists who are challenged about their use of one medication over another will continue to rely upon expert witnesses, peer-reviewed literature, and well-documented efforts to provide quality care. Furthermore, OMIC feels that the ophthalmologist is in the best position to determine how to treat an individual patient, and whether it is appropriate to take the cost of a

medication into account. Our professional liability policy provides coverage for such use,
including ongoing use of Kenalog,TM as well as off-label use of TriesenceTM and Trivaris.TM
The remainder of this document further clarifies OMIC’s understanding of “off-label” use of
approved medications, and offers risk management recommendations specific to intravitreal
administration of triamcinolone acetonide. A sample consent form
for IVTA can be found on
the OMIC website. If you are using TriesenceTM or TrivarisTM for on-label use only, delete the
paragraph that addresses off-label use as well as the first bullet point on it in the consent
section. If you are using Kenalog,TM include both the section on off-label use, and the second
bullet point in the consent section. “OFF-LABEL” USE OF AN APPROVED MEDICATION
As Dr. E. Randy Craven and attorney Elizabeth C. Moran note in “The Medicolegal Risks of
Using Off-Label Drugs and Devices,” the production, sale, and clinical research of new drugs
and medical devices are subject to regulation by the Food and Drug Administration (FDA) and
the Department of Health and Human Services (HHS).When a drug or device is approved for
medical use by the FDA, the manufacturer produces a “label” to explain the indications, dose,
side effects, and complications.
The FDA has clarified that once it approves a device/medication, physicians may use it “off-
label” for other purposes if they are well-informed about the product, base its use on firm
scientific information and sound medical evidence, and maintain records of its use and effects.
The FDA considers such use to be “the practice of medicine,” which it does not directly regulate.
The FDA does, however, expect physicians to practice in a manner that is designed solely to
insure the well-being of the individual patient. Accordingly, the FDA generally does not oversee
or interfere with a physician's individual practice decisions unless a physician is himself
marketing or selling a drug or device, acting as an investigator in clinical research, or gathering
information about safety or efficacy. PERFORM A RISK ANALYSIS
Craven and Moran suggest performing a risk analysis before first using a drug “off-label,” a
recommendation echoed by OMIC Staff Attorney Kimberly Wittchow in “When FDA Leaves
Physicians to Its Own Devices.” If the medication is an existing drug used in a non-approved
manner, first consider whether its use poses significantly increased risks to the patient. Second,
consider whether its use can be expected to bring good results without a higher complication

rate. If it presents no more risk to the patient than that of daily living, proceed with its use, as, for
example, the use of aspirin for anticoagulation after a central retinal vein occlusion. If there is an
increased risk to the patient, ask yourself if at least a reasonable number of physicians in your
specialty are using the treatment; e.g., have peer reviewed articles been published supporting
the use of the new treatment and is the treatment being used by a reasonable number of other
practitioners with the same level of training as you? As part of the risk analysis, consider what
you will tell the patient before initiating treatment. If the proposed treatment consists primarily of
an “off-label” medication, the physician should obtain the patient’s informed consent and
disclose the FDA non-approved status. RISK PROFILE OF TRIAMCINOLONE ACETONIDE
A risk analysis of TA shows that while there are known, serious risks, its use in ophthalmology is
both widespread and well-studied.IVTA is the subject of dozens of studies in the peer-
reviewed scientific literature as well as two ongoing National Eye Institute randomized clinical
trials. This drug is used to treat a wide range of proliferative, inflammatory, occlusive, and
edematous diseases of the retina and eye. Conditions treated with IVTA include diabetic
macular edema, exudative age-related macular degeneration, edema from central retinal and
branch retinal vein occlusions, chronic uveitis, and pseudophakic cystoid macular edema.1,
Anterior segment and retinal specialists have also used it as a surgical adjunct “to help visualize
the vitreous during epiretinal peels or internal limiting membrane peels.” For some of these
conditions, TA is considered the first line of treatment; for others, it is the only available medical
modality. Its use reduces edema, vascular leakage, and vascular growth, resulting in improved
visual acuity. In November, 2007, and June, 2008, the FDA approved two TA products for
ophthalmic use, TriesenceTM and Trivaris.TM
Steroids are associated with significant risk, regardless of why they are prescribed or their route
of administration. Intravitreal and other ophthalmic administration techniques were developed to
minimize the risk of systemic steroids and maximize the effectiveness of the drug. As studies
have shown, however, these routes are also linked to adverse events. Intravitreal injections, for
example, are known to result in infection (endophthalmitis), retinal detachment, secondary
glaucoma, and lens trauma/acute cataract. Rare complications of this technique include
hemorrhage, precipitated angle closure, elevated intraocular pressure with perfusion
compromise, wound leak with hypotony, and anaphylactic reaction to either the agent or the
Steroids themselves lead to the development of cataracts and glaucoma, risks that may
increase with repeated injections.8 Some patients are “steroid responders,” and may develop a
dramatic rise in IOP. 1 Additionally, benzyl alcohol, the preservative in KenalogTM (triamcinolone
acetonide), has anecdotally been reported to cause a sterile, inflammatory reaction.9 Animal

RISK MANAGEMENT RECOMMENDATIONS
In line with previous recommendations from OMIC about “off-label” use, we encourage
ophthalmologists to follow these suggestions to promote patient safety and reduce liability
• Patient and treatment selection
• Determine what is in the best interests of the particular patient.
• If there is an alternative FDA-approved medication for the patient’s ophthalmic condition,
consider first treating the patient with it. Consider using TriesenceTM or Trivaris.TM Conduct and document pertinent diagnostic/monitoring tests, such as fluorescein angiogram and OCT, as part of the evaluation. If applicable, note lesion type, location, size, and presence of subretinal fluid.
• Document prior treatment efforts, if any, and the decision-making process that led to the
• Preparation of the medication
• Proper aseptic technique should be utilized during the preparation and administration of
• Most ophthalmologists use the commercially available form of KenalogTM. A minority,
however, choose to administer a preservative-free form that is usually prepared by a compounding pharmacy, a process that may introduce other risks. Compounding pharmacies must comply with Chapter 797 of the United States Pharmacopeia (USP), which sets standards for the compounding, transportation, and storage of compounded sterile products (CSP). There is now a Pharmacy Compounding Accreditation Board, which can verify that the pharmacy is adhering to these standards. To ensure safe compounding and administration, ophthalmologists should ask the compounding pharmacy 1) to prepare the medication under aseptic conditions, 2) to confirm the dose and sterility, 3) to label each container or syringe with the strength, lot number, storage, and “beyond use” instructions, 4) to verify that it is licensed/registered in the state in

o Inform the patient that the drug was not approved for the condition they have, but that
off-label use is a legal and necessary aspect of the practice of medicine.
• If using Kenalog,TM discuss “off-label” status.
o Inform patients of this form of TA’s off-label status and told that the manufacturer has
recommended against ophthalmic use, but that the FDA and attorneys have confirmed that ongoing use is legal as part of the “practice of medicine.” Inform the patient that a two products of TA have been approved for use in the eye.
o In general, informed consent may be considered to have ongoing force and effect until
1) the patient revokes the consent (by refusing subsequent injections) or 2) circumstances (i.e., the patient’s medical or ocular condition) change so as to materially affect the nature of the procedure or the risk/benefit ratio.
o Prior to subsequent injections, the continued need, effectiveness, and safety of the
medication should be evaluated and documented.
o If the patient’s medical or ocular condition changes to the point that the risk/benefit
ratio is affected, it would be prudent to either discontinue treatment or obtain and document informed consent again. If the patient refuses subsequent injections, ascertain and address the reasons, and document the conversation and treatment
• Documentation of care
o Document the diagnostic process, as well as the decision-making process that led to
choosing TA as the treatment for the patient.
o Note the results of earlier attempts at treatment and the results of diagnostic tests. o Document the informed consent discussion in the chart and ask the patient to sign a
procedure-specific consent form. Document any refusal of care, and include the reason.
o Note the dose, lot number of the vial, and any reactions to the injection and how they
o Provide discharge and follow-up instructions, and document that they were given. o Document efforts to monitor for and respond to complications. o Document referrals to sub-specialists, and place a copy of the consultation letter in the
