In this real-life case study, OMS can learn how patient autonomy and clinical standards may conflict when making treatment decisions. The case points out the risks of prioritizing patient requests over the standard of care, and how such decisions can lead to Dental Board sanctions or malpractice claims.
Key Concepts
- Sanctions from Board complaints
- Does malpractice insurance cover Board fines?
- Patient autonomy vs. the standard of care
Underlying facts
Dr. P was an oral and maxillofacial surgeon who returned to her relatively rural hometown to practice, making her the only such specialist within a nearly two-hour drive. Most members of the community had known her since she was a child, and all were quite appreciative that she had likely sacrificed financially to come home rather than work in the large city where she trained. Late in the afternoon on the last calendar day of the month, W, a local resident, presented to the office in excruciating pain emanating from a grossly decayed and severely periodontally involved lower bicuspid, wanting to have it extracted. Dr. P knew from previously treating him that he had a heart valve replacement years ago and was taking warfarin daily since that surgery. In anticipation of an extraction that day, W took the antibiotics he kept on hand that had been prescribed for him by his cardiologist. However, prior to extractions Dr. P had performed for W in the past, W stopped his anticoagulant days before the procedure, on the advice of his physician, such that his INR would reside below its usual target of 3.5, in the 2.5-3.0 range for surgery, after which the anticoagulant would be restarted a day later.
On the day of presentation, W had not stopped his anticoagulant therapy, and he reported to Dr. P that his most recent INR, about a week or so prior, was “on the high side” at roughly 4.5. Dr. P expressed to her patient that she did not feel comfortable extracting a tooth, particularly one with periodontal disease, at that INR level. Dr. P contacted W’s cardiologist who agreed with the oral surgeon’s bleeding concerns and suggested deferring surgery. After the call, Dr. P reiterated her concerns, suggesting that W see his cardiologist to dial down the warfarin so that an acceptable INR level could be reached for surgery.
W became upset, complaining about his unrelenting pain and, perhaps more significant to him, the fact that the health insurance policy provided by his employer was expiring the next day in favor of a less expensive medical plan that had a high deductible and did not reimburse for dental procedures. He pleaded with Dr. P to accommodate him, as “a favor from one friend to another.” What she would later say was against her better judgment, she gave in and performed the extraction uneventfully and packed the site with a gelatin sponge and a topical coagulating agent known to be effective for that purpose. Gauze pressure was applied, with hemostasis achieved, and W went home.
W’s wife called Dr. P the following morning, telling her that overnight, W had been taken by ambulance to the nearest hospital due to persistent heavy bleeding from his mouth. There, he was admitted to the medical service (as there was no dentist or OMS on site), where he was fluid-managed and transfused, leading to the stoppage of bleeding and W’s hemodynamic stability. Dr. P visited W after her office hours ended, finding W in great distress emotionally, but stable physiologically. W was discharged home two days after admission, with no further complications. His new medical insurance left him with a sizeable bill for emergency transport and hospital care.
Legal action
Quickly forgetting the “favor” given to him, W became angry with Dr. P when she refused to pay for his medical expenses. Unable to find a lawyer who would sue Dr. P, given the lack of permanent physical damage and limited monetary expenses, he filed a lawsuit pro se, serving in effect as his own attorney. Dr. P was assigned counsel through her malpractice insurance carrier, who quickly took procedural steps to have the case dismissed. W did not have the capability to fight legal battles against a lawyer, so the court did, in fact, dismiss the case.
W searched online for other options available to him, and he came upon a Complaint Form which he completed and sent to the state Dental Board. W detailed his version of events, submitting copies of his medical, ambulance, and hospital records. Upon receiving W’s complaint, the Board contacted Dr. P, seeking her office records and an explanation of events. With the assistance of the same attorney who had gotten the lawsuit dismissed, she complied.
Dr. P was interviewed by a 3-member Board panel, accompanied by her attorney. The thrust of Dr. P’s position was that she was there to serve the needs of an underserved community, which sometimes requires compromises from the ideal. She explained that she had to make an on-the-spot choice, weighing pros and cons, and determined that taking this patient out of severe pain – which she believed could not be adequately accomplished with medications alone – and trying to spare him non-reimbursable oral surgery expenses that he could not easily afford, was her ethical duty under the tenets of patient autonomy and non-maleficence (“do no harm”). She acknowledged that performing the extraction without a known acceptable INR level was against her better medical judgment but in concert with her best ethical judgment.
The Dental Board was unmoved. Its members determined that Dr. P had conducted herself in an unprofessional way, improperly weighing treatment options and succumbing to the desires of a lay person who could not reasonably understand all of the potential ramifications. The report of sanction, which would be posted on the Board’s public-facing website, stated that Dr. P mischaracterized the concept of autonomy so as to include patient self-determination at the expense of patient health, and that she created a situation which led to increased patient harm, that could have even ended up worse; “Patients have the right to refuse, but not to dictate.” Realizing that suspending Dr. P would hurt the community greatly, the Board’s sanctions were limited to a substantial monetary fine and a licensing requirement of continuing education in the areas of ethics and management of medically compromised patients.
Takeaways
A fundamental concept in this case study is that patients have multiple avenues to seek redress against OMS (and all dental practitioners): suing them for malpractice and/or lodging Board complaints. While malpractice insurance will provide legal representation and financial protection (up to policy limits) in the event of a lawsuit based upon malpractice, the same is not true when a Board complaint is filed. Most malpractice policies will offer legal representation to insureds for Board proceedings, but they do not indemnify for monetary penalties, and they cannot mitigate sanctions, educational requirements, or other levies by state Boards.
Had the malpractice litigation moved forward to be decided by a jury, instead of having been dismissed, it is fair to say that an expert for the plaintiff (patient) would have provided the opinion that, despite all of the underlying factors – change of insurance coverage as of midnight, patient pain, antibiotic prophylaxis having already been taken – Dr. P departed from the standard of care in performing an extraction on a patient with an elevated INR level, to the extent that even she acknowledged was against her better clinical judgment, with that departure directly leading to a true medical emergency. It is also reasonable to expect that W’s cardiologist would have testified that he agreed with the stated bleeding concerns of Dr. P and that he suggested holding off on the extraction until the patient was less anticoagulated. To counter those opinions, an expert for Dr. P would need to feel comfortable with the actions taken by Dr. P and be willing to express them in front of a trial jury. A wild card, which is jurisdictionally and factually dependent, is whether the findings of the Dental Board would be permitted by the trial judge to come into evidence. In the end, a jury would make the ultimate determinations.
It is an undisputed reality that oral surgeons often have non-clinical pressures placed upon them – by patients, by referring dentists, by employers, by personal obligations – to take clinical actions that they would preferably not perform. And it is also true that some situations pit ethical concepts against standards of care. Which directions they choose become based upon an unavoidable mix of personal philosophies, professional experiences, and external forces. Realizing these conflicts can go a long way toward making the most idealized choices, although sometimes not easy. Professionalism means placing a patient’s best interests, however that might look, ahead of all else. The dentistry and the medicine are often times the simple parts.
