Patient Sues Oral Surgeon After Unforeseeable Seizure

Reading time: 8 minutes

In oral surgery, medical emergencies, even if unforeseen, can still happen. In this case study, a patient presents to an oral surgeon for an implant placement procedure under local anesthesia. During the procedure, the patient suffers a grand mal seizure and is transported to a medical center for care. Later, the patient sues the oral surgeon for negligence, despite lacking medical evidence for the cause of the seizure.

Background Facts

Dr. H is a mid-career, experienced practitioner who has focused on implant dentistry for some years. J, a 50-year-old man with a disclosed history of hypertension, controlled with medication per his history, but no other known medical conditions, presented to Dr. H for her to place a single implant at the site of tooth #30, which had been lost 3 years prior due to a fracture.  Radiographs demonstrated that the edentulous area had filled in well with bone that appeared to be of adequate volume and density to accommodate a fixture upon which a crown could eventually be placed.

A 13 mm implant was chosen to be placed into a radiographically-measured 15.5 mm space superior to the inferior alveolar canal. J saw no reason to be sedated for the procedure, as he had always been comfortable during a host of procedures performed under local anesthesia alone. After a thorough informed consent process took place, with written memorialization, Dr. H delivered a long buccal block as well as infiltrations, using 2 carpules of local anesthesia with epinephrine. J tolerated that well, with the area becoming anesthetized within a few minutes, as demonstrated by the lack of any response to a sharp instrument tested at various buccal and lingual locations.

After Dr. H elevated a soft tissue flap following a crestal incision, J became noticeably jittery and started to move around with “odd” opening and closing movements of the jaw, as Dr. H attempted the implant osteotomy. Dr. H briefly stopped work, but as she began again, the movements quickly progressed into what was clearly apparent as a grand mal seizure. Before she was able to stop the bur and remove the handpiece from the mouth, the osteotomy bur pierced through the buccal soft tissue and lower lip, on both sides of the commissure. With Dr. H’s assistance and instruction to her staff, the chairside assistant and Dr. H protected J from causing injury to himself and others, while the receptionist called for EMS.

By the time ambulance personnel arrived, the seizure had ended with J appearing to be in an altered state of awareness. Dr. H placed gauze over the lacerations and maintained hand pressure on them to minimize bleeding. J was then transported to a local medical center, where post-seizure care was provided and where oral and maxillofacial surgery residents repaired the lacerations, and debrided and closed the crestal incision.

J remained an in-patient for a complete neurological work-up, which never reached a conclusion as to the cause of the seizure. After returning home, he shortly resumed his usual activities while remaining under the watchful care of a neurologist. The scar which developed had a keloid appearance which bothered J greatly. Despite two scar revision procedures performed by a plastic surgeon, J was constantly self-conscious about his facial appearance, embarrassed to meet new people, both at work and in his social life.

J contacted a “malpractice law firm” whose poster he saw on a subway, wondering whether he might be able to be compensated for what he viewed as a physical deformity. The attorney assigned to handle J’s case soon advised J that he would be filing suit against Dr. H. After Dr. H was served and then assigned defense counsel by her malpractice carrier, the discovery process began. In the usual discovery paperwork, J, through his counsel, claimed that his facial scarring was directly caused by the negligence of Dr. H, namely that she had failed to protect him against the events which took place by having a proper finger rest, that she had failed to timely realize the prodromal stage of the seizure and to act upon that, and in delivering an excess amount of local anesthesia so as to cause the seizure.

The attorneys for Dr. H gathered all of J’s current and prior medical records, with particular focus on J’s post-seizure neurology work-up. They took specific note of the facts that J’s past medical history was as he had described it, and that the neurologist was unable to determine the cause of the seizure.

Armed with this information, as well as the expert affidavits of a dentist, an oral and maxillofacial surgeon, and a neurologist, they sought immediate dismissal of the case by way of a legal approach known as a motion for summary judgment (MSJ). In those MSJ papers, the defense attorneys argued, with the back-up of the experts, that no finger rest could have possibly prevented the seizure from occurring, and without the seizure, there would have been no laceration to develop into a keloid; that seizure prodromal stages are individual to every patient, and with no seizure history, Dr. H could not possibly have foreseen a potential seizure – no less know this patient’s prodromal signs – so as to interpret “odd” movements as being the onset of a seizure; that the amount of local anesthetic was far from excessive; and finally, but perhaps most important, that without a medically-known cause for the seizure, the case cannot legally stand.

In opposition, J’s attorney obtained his own experts, who, in essence, claimed that the adequacy of the finger rest, the lack of timely realization of the seizure prodome (so as to more quickly remove the bur from the mouth), and the amount of local anesthetic given, should be factual matters left for a jury, rather than legal matters to be determined before trial by a judge.  Interestingly and tellingly, J’s opposition did not address the unknown cause for the seizure at all. However, it did add in the claim that Dr. H did not take J’s blood pressure prior to the treatment, in direct contravention of recent guidelines distributed by national organized oral surgery.

With the court having read all of the motion papers, at the close of oral arguments by both counsel before the court, the case was dismissed in its entirety. The court acknowledged that there could reasonably be disagreement as to whether Dr. H acted appropriately or negligently regarding the adequacy of the finger rest, or her noticing and acting on an impending seizure, or in how much local she delivered, or even in not measuring the patient’s pre-procedure blood pressure. But there could be no disagreement, the court reasoned, that there was no non-speculative way for a jury to conclude that any such negligence was the direct cause of the seizure, because no medical cause for the seizure – whether negligent or otherwise – had ever been determined.

Takeaways

For a plaintiff to be successful in an oral surgical malpractice case, the burden squarely falls on them to prove that (1) there was negligence on the part of the doctor (2) which directly caused (3) the injury complained-of. Failure to prove any one of those three elements is fatal to the claim. Consequently, a defendant need only disrupt any one of those elements to be successful in defense. Here, it was the judge, prior to trial, who determined that the “causation element” could not be proven by the plaintiff, because, without any medical evidence of the cause of the seizure, the claim that Dr. H’s negligence caused it was pure [legally unsound] speculation. In most cases, it is the jury that goes through a similar assessment, although based on the facts rather than legal principles, as to each of the required elements. And without that causation element proven – or as here, even able to be proven – the defendant oral surgeon prevailed, even though she might have arguably been negligent in some aspect of her care. Such is the world of law.

A motion for summary judgment is premised upon a lack of dispute, as to at least one of the required-to-be-proven case elements, between the parties. Therefore, a motion for summary judgment, when submitted by a defendant, need only demonstrate that at least one of the required elements cannot be met by the plaintiff. Here, Dr. H’s attorneys demonstrated to the court that the element of causation could not possibly be met by the plaintiff, warranting immediate, pre-trial dismissal. The court agreed.

The issue of the lack of the measuring of J’s blood pressure by Dr. H raises a few considerations. First of all, while it is true, as plaintiff contends, that guidelines do exist which suggest the taking of a patient’s blood pressure before every invasive procedure, those guidelines do not represent the standard of care, a concept that oral surgical organizations are quick to point out when issuing guidelines. But even if this court had accepted the guidelines as being the equivalent of standard of care, there was no medical evidence that an elevated blood pressure was the cause of this seizure, as previously discussed. The same can be said regarding the propriety or excessiveness of anesthetic dose, because, once again, the inability of the plaintiff to prove the causation element was fatal to his case.

Finally, we briefly discuss the concept of foreseeability, which is no stranger to issues determined by courts. Perhaps it is more accurate to speak about “foreseeability” as “reasonable foreseeability.” There are so many medical conditions and potential medical conditions that afflict patients, that it would be nearly impossible to foresee every medical problem that might come to pass on any given patient. So, while it is readily seen as reasonably foreseeable that even a well-controlled diabetic might suffer from a hypo- or hyper-glycemic event during a procedure, that same level of reasonableness does not exist so as to foresee a grand mal seizure in a patient with no seizure or neurologic history whatsoever. Yes, courts will often hold practitioners liable for foreseeable events, but that is generally interpreted as reasonably foreseeable events. The takeaway here is when you hear hoof beats, think horses, not zebras.

In this real-life case study, oral and maxillofacial surgeons will see how a missed biopsy report led to a devastating outcome and costly litigation. The article explores the clinical and administrative failures that allowed a cancer diagnosis to go unnoticed and offers practical risk management strategies to prevent similar tragedies.

Key Concepts

  • Patient communication in OMS offices 
  • Ensuring timely review of lab reports
  • How proactive follow-up prevents patient harm

Underlying facts

B, a 54-year-old longtime smoker, had many teeth removed in her adult life due to inadequate oral hygiene. Whenever she went to the dental office (T), it was almost always because of acute symptoms, so she generally ended up in the hands of the oral surgeon currently working at this large group practice in her town. Dr. I was fairly new to oral surgery practice, so he came to the dental office (T) about once every second or third week, as T's needs dictated, while building his own practice in the neighboring county.

When B presented to T, after having not seen any dentist for some 18 months, she complained to the front desk staff of a persistent "sore" in the floor of the mouth, adjacent to where the second and third molars would have been. B was immediately assigned to see Dr. I, who was there that day. Upon examination, Dr. I noted a 1-1.5 cm centrally eroded area of erythroplakia, which bled on light touching. Dr. I told B that he wanted to take a tissue sample to be biopsied, but, not wanting to make her unnecessarily anxious, he said that this was simply a precautionary measure, albeit not overly concerning, despite his own concerns. With local anesthesia, Dr. I removed a small section of the lesion (which did not require any suturing) and sent it to a local lab for pathologic evaluation.

Before leaving the office, B said to Dr. I, "I assume that you'll call me if it's anything bad," to which Dr. I responded, "Of course." Eight days later, a mailed biopsy report was opened at T's front desk by the staff person who regularly handled mail. That staff member placed the report in the physical paper file for B, without reading it or showing it to any dentist, so the diagnosis of "consistent with squamous cell carcinoma" became known to nobody in the office. Not hearing any news, B presumed that all was fine. By the time Dr. I next worked at T, nearly 3 weeks after his prior visit, he had forgotten about the procedure he had performed on B, and nobody knew to alert him to the contents of the report.

Almost a year after seeing Dr. I, B had a hysterectomy. During her pre-operative evaluation, the anesthesiologist noticed a large sublingual lesion while assessing intubation and airway considerations. The anesthesiologist then started the post-surgical process of having B evaluated by the hospital's otolaryngology department, which led to a complete work-up that revealed that the oral squamous cell carcinoma had metastasized broadly. Despite a hemi-mandibulectomy, neck dissection, and a course of chemotherapy, B passed away approximately 2 years after her visit with Dr. I. She left behind an 18-year-old daughter, E.

Legal action

Distraught over the loss of her mother and in dire financial straits, she contacted an attorney to look into her options. E advised the attorney that her mother was complaining about a sore in her mouth for years, and had it checked out by an oral surgeon, "but it was nothing." The attorney made an application to the court to have E appointed as the representative of B's estate, which was granted, after which the records from T and the pathology lab, among others, were requested and received. E's lawyer immediately saw the biopsy report that had been sent to Dr. I at the office of T but found no evidence of any follow-up. E confirmed that she believed that nobody from the dental office ever told her mother about the biopsy findings.

The attorney enlisted the services of an oral and maxillofacial surgeon, a pathologist, and an oncologist to review the records and offer their opinions about potential liability and causation. The oral surgeon determined that Dr. I acted appropriately in immediately taking a specimen of the lesion and sending it for histologic evaluation, but that he failed to follow up on it, thereby leading to the failure of notifying B so that she could timely receive care and treatment; the office, T, was also criticized for not having a system in place whereby every medical and dental document that came in the mail must be reviewed by a dentist. The pathologist was minimally critical of the treating pathologist for not making a phone call to Dr. I or to T upon his abnormal finding, but in the end, the pathologist was of the view that the standard of care required communication to the treating oral surgeon of an abnormal finding, but that standard did not require any specific method of communication. Finally, the reviewing oncologist concluded that, had B been timely sent on a path for a thorough work-up and treatment following the initial biopsy, she would have been able to be treated by less invasive means and would quite likely have survived.

The attorney filed suit against Dr. I and T, asserting claims of B's wrongful death and of pain and suffering for needing the aggressive treatment she had and for going through a slow, painful course toward her death. Dr. I and T alerted their respective malpractice carriers upon being served with the lawsuit papers, and they were assigned different defense counsel. Discovery went forward, with depositions of E, Dr. I, and T's mail clerk taking place, as well as the exchange of relevant documents and statements of expert opinions.

Those expert opinions on behalf of both defendants, Dr. I and T, were not at all supportive, essentially echoing the opinions of the experts retained by the plaintiff's counsel. Realizing early on in the litigation that a defense would be quite challenging, if even realistically possible, the defendants and their malpractice carriers agreed to work toward settling the case with E, through her attorney, which was accomplished by means of a substantial payment, the majority of which was on behalf of Dr. I, the oral and maxillofacial surgeon.

Takeaways

Starting with something of a procedural point, we note that Dr. I and T were represented by different defense counsel. While here, there were different malpractice carriers for both defendants, so the assignment of different counsel seems logical, intuitive, and expected; that is not necessarily always the case. Even if the defendants were insured by the same company, they might also have been assigned different defense attorneys. In some circumstances, different defendants are represented by the same attorney, whether insured by the same or different carriers. The decision is often based upon the important consideration as to whether the various defendants appear to have all of their defense interests aligned, so that they can present a united defense front; otherwise, a potential conflict might well exist between the parties and their attorneys. However, there are times when multiple defendants begin a case with the same attorneys, but that needs to be separated out later in the litigation, if facts or circumstances arise that would lead to a likely conflicting approach to all defenses.

Moving to the clinical issues as they relate to Dr. I, particularly in situations of an itinerant oral surgeon who spends time working in the offices of others, where practice protocols might not be as patient-protective as would be best desired, or as they would be in their own practices. Regardless of the setting in which, as here, a biopsy is performed to assess a concerning situation, the burden of following up on results lies squarely with the surgeon who performed the procedure. Absent that, the patient can easily be inappropriately led into a state of blissful ignorance, as B was in this case study, presuming that nothing was amiss because she did not hear from the office or Dr. I; as a direct result, B carried on as though her health was good, until the ever-growing lesion was serendipitously discovered, by which time cure prospects were no longer viable. Yes, defense counsel could have argued that the time delay until discovery and treatment did not make a difference in the ultimate outcome, of course, based upon an oncology opinion saying so, but such approaches are traditionally difficult to maintain before a jury, whose members might well see it as "making excuses" and "blaming the victim."

The procedures of office T, which directly had a negative impact upon Dr. I as an itinerant, and upon B, allowed non-professional staff to bypass the professionals regarding a document as important as a biopsy report. It is the choice of every office and every practitioner to determine for themselves what are the most efficient and safe ways to ensure that the provision of critical information is not left to processes such as "don't worry if you don't hear from us,” or "call us if you don't feel better." Risk management principles are best carried out by professionals who affirmatively initiate follow-up in all clinical circumstances where awareness of continued symptoms, of worsening symptoms, or of static conditions is critical to the patient's well-being: biopsies, infections, and pain. While office staff can appropriately have a hand in setting up administrative systems that make certain that proper follow-up care takes place, the responsibility for its being carried out rests with the professional.

There is no doubt that practicing as an itinerant, particularly while new surgeons' own practices are growing, has a host of benefits. But what comes with that is at least a modicum of loss of administrative control, which can easily flow into loss of clinical control. The burden of liability does not change, regardless of setting or business ownership.

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.

Patient care is complex and personal, which is why it can lead to malpractice risk for oral and maxillofacial surgeons (OMS). That’s why preparing to face malpractice claims before they arise is an essential aspect of risk management. By implementing proactive strategies, OMS can better protect their practice and their patients.

Key Concepts     

  • What is an OMS malpractice claim?
  • Preventing OMS malpractice claims
  • Securing OMS malpractice insurance

Oral surgery is an essential healthcare service. As an OMS, you play an important role in your patients' well-being. However, the responsibility of patient care comes with the risk of malpractice claims.

Malpractice claims can be financially draining and damaging to your professional reputation. That's why it's helpful to know the risks and identify ways to reduce them in your practice. In this article, we will share tips to help reduce the likelihood of malpractice claims in oral surgery and discuss the importance of malpractice insurance for OMS.

Understanding OMS malpractice claims

Malpractice occurs when an OMS fails to provide treatment in conformity with the standard of care, thereby making it negligent, resulting in harm to a patient. This can include incorrect or missed diagnoses, improper treatment, or improper choice of or planning for a procedure. To avoid these situations, it's vital to have a comprehensive claim prevention strategy in place.

Acquiring OMS malpractice insurance is a crucial aspect of your claim prevention strategy. It can provide financial protection against claims, covering legal fees, settlements, and damages awarded after a trial. Choosing the best malpractice insurance requires thorough research of available coverage options.

MedPro Group offers tailored malpractice insurance for OMS, ensuring that you have the protection you need to practice with peace of mind.

Key strategies for preventing malpractice claims

In addition to getting a malpractice insurance policy, what can you do to help prevent malpractice claims? Here are some useful strategies to consider:

Keep detailed patient records

  • Maintaining detailed and accurate patient records is essential. This includes documenting patient histories, examinations, treatments, and any communication. Keeping thorough records is important for providing consistent care and can be crucial in a legal dispute. Records should never be altered. Complete and contemporaneous documentation is a key factor in maintaining professional credibility.

Stay informed and educated

  • Continuing education allows you to stay up to date with the latest oral surgery techniques and standards of care. Going to workshops and classes can help you take better care of your patients and reduce the possibility of mistakes.

Manage your practice effectively

  • Continuing education allows you to stay up to date with the latest oral surgery techniques and standards of care. Going to workshops and classes can help you take better care of your patients and reduce the possibility of mistakes.

Communicate clearly with patients

  • It's important to talk openly with patients about their treatment. Obtain comprehensive informed consent for all treatments, ensuring patients understand what to expect, including possible risks, from the proposed treatment. Clear communication can help prevent misunderstandings that could lead to malpractice claims.

Practice within your scope and abilities

  • As an OMS, it's important to only practice within the scope of your expertise and licensure. Avoid offering treatments or advice outside of your professional capacity, as this can increase your malpractice risk. Similarly, non-professional office staff should never be permitted to provide any dental or medical advice to patients. If you feel as though the patient's condition or treatment would be better handled by a practitioner with particular expertise regarding the issue at hand, refer the patient out.

Follow the standard of care

  • Adhering to the standard of care – what a reasonable practitioner would do under similar circumstances – can help minimize the chance of mistakes and your malpractice risks. 

Prioritize patient safety

  • Always prioritize patient safety during treatments. Be mindful of techniques that pose risks, especially for patients with pre-existing conditions or complex medical histories. If you're uncertain about a particular treatment, seek a second opinion or refer the patient to a dental specialist.

How to handle an OMS malpractice claim

In the unfortunate event of a malpractice claim, it's important to act promptly and professionally. Here are some initial steps to consider:

Contact your insurance provider

Immediately notify your OMS malpractice insurance provider if you receive a claim or have reason to believe a claim is imminent. Avoid discussing the claim with anyone before contacting your insurance carrier. They will help guide you through the process and provide legal representation if necessary.

Do not alter patient records

A clinical note should be completed as contemporaneously as possible with treatment. If you notice an error in your original note or omitted information, do not alter the original note. Rather, make an addendum and reference the date of the original note and the date of treatment, and then explain your addition. Altering records can be seen as an attempt to cover up the facts and can severely harm your ability to resolve a claim.

Cooperate with your claims consultant

Work closely with your malpractice insurance carrier’s claims team. Provide them with all the necessary documentation and information to address the claim

Malpractice insurance considerations

Facing malpractice claims in oral and maxillofacial surgery can be daunting, but acquiring the best malpractice coverage can help you manage risk. By being proactive, you can keep your patients safe and practice with confidence.

When purchasing OMS malpractice insurance, keep the following in mind:

Coverage limits

  • Make sure your policy provides adequate coverage to protect your assets and practice in the event of a claim.

In this real-life case study, oral and maxillofacial surgeons will see how a missed biopsy report led to a devastating outcome and costly litigation. The article explores the clinical and administrative failures that allowed a cancer diagnosis to go unnoticed and offers practical risk management strategies to prevent similar tragedies.

Key Concepts

  • Patient communication in OMS offices 
  • Ensuring timely review of lab reports
  • How proactive follow-up prevents patient harm

Underlying facts

B, a 54-year-old longtime smoker, had many teeth removed in her adult life due to inadequate oral hygiene. Whenever she went to the dental office (T), it was almost always because of acute symptoms, so she generally ended up in the hands of the oral surgeon currently working at this large group practice in her town. Dr. I was fairly new to oral surgery practice, so he came to the dental office (T) about once every second or third week, as T's needs dictated, while building his own practice in the neighboring county.

When B presented to T, after having not seen any dentist for some 18 months, she complained to the front desk staff of a persistent "sore" in the floor of the mouth, adjacent to where the second and third molars would have been. B was immediately assigned to see Dr. I, who was there that day. Upon examination, Dr. I noted a 1-1.5 cm centrally eroded area of erythroplakia, which bled on light touching. Dr. I told B that he wanted to take a tissue sample to be biopsied, but, not wanting to make her unnecessarily anxious, he said that this was simply a precautionary measure, albeit not overly concerning, despite his own concerns. With local anesthesia, Dr. I removed a small section of the lesion (which did not require any suturing) and sent it to a local lab for pathologic evaluation.

Before leaving the office, B said to Dr. I, "I assume that you'll call me if it's anything bad," to which Dr. I responded, "Of course." Eight days later, a mailed biopsy report was opened at T's front desk by the staff person who regularly handled mail. That staff member placed the report in the physical paper file for B, without reading it or showing it to any dentist, so the diagnosis of "consistent with squamous cell carcinoma" became known to nobody in the office. Not hearing any news, B presumed that all was fine. By the time Dr. I next worked at T, nearly 3 weeks after his prior visit, he had forgotten about the procedure he had performed on B, and nobody knew to alert him to the contents of the report.

Almost a year after seeing Dr. I, B had a hysterectomy. During her pre-operative evaluation, the anesthesiologist noticed a large sublingual lesion while assessing intubation and airway considerations. The anesthesiologist then started the post-surgical process of having B evaluated by the hospital's otolaryngology department, which led to a complete work-up that revealed that the oral squamous cell carcinoma had metastasized broadly. Despite a hemi-mandibulectomy, neck dissection, and a course of chemotherapy, B passed away approximately 2 years after her visit with Dr. I. She left behind an 18-year-old daughter, E.

Legal action

Distraught over the loss of her mother and in dire financial straits, she contacted an attorney to look into her options. E advised the attorney that her mother was complaining about a sore in her mouth for years, and had it checked out by an oral surgeon, "but it was nothing." The attorney made an application to the court to have E appointed as the representative of B's estate, which was granted, after which the records from T and the pathology lab, among others, were requested and received. E's lawyer immediately saw the biopsy report that had been sent to Dr. I at the office of T but found no evidence of any follow-up. E confirmed that she believed that nobody from the dental office ever told her mother about the biopsy findings.

The attorney enlisted the services of an oral and maxillofacial surgeon, a pathologist, and an oncologist to review the records and offer their opinions about potential liability and causation. The oral surgeon determined that Dr. I acted appropriately in immediately taking a specimen of the lesion and sending it for histologic evaluation, but that he failed to follow up on it, thereby leading to the failure of notifying B so that she could timely receive care and treatment; the office, T, was also criticized for not having a system in place whereby every medical and dental document that came in the mail must be reviewed by a dentist. The pathologist was minimally critical of the treating pathologist for not making a phone call to Dr. I or to T upon his abnormal finding, but in the end, the pathologist was of the view that the standard of care required communication to the treating oral surgeon of an abnormal finding, but that standard did not require any specific method of communication. Finally, the reviewing oncologist concluded that, had B been timely sent on a path for a thorough work-up and treatment following the initial biopsy, she would have been able to be treated by less invasive means and would quite likely have survived.

The attorney filed suit against Dr. I and T, asserting claims of B's wrongful death and of pain and suffering for needing the aggressive treatment she had and for going through a slow, painful course toward her death. Dr. I and T alerted their respective malpractice carriers upon being served with the lawsuit papers, and they were assigned different defense counsel. Discovery went forward, with depositions of E, Dr. I, and T's mail clerk taking place, as well as the exchange of relevant documents and statements of expert opinions.

Those expert opinions on behalf of both defendants, Dr. I and T, were not at all supportive, essentially echoing the opinions of the experts retained by the plaintiff's counsel. Realizing early on in the litigation that a defense would be quite challenging, if even realistically possible, the defendants and their malpractice carriers agreed to work toward settling the case with E, through her attorney, which was accomplished by means of a substantial payment, the majority of which was on behalf of Dr. I, the oral and maxillofacial surgeon.

Takeaways

Starting with something of a procedural point, we note that Dr. I and T were represented by different defense counsel. While here, there were different malpractice carriers for both defendants, so the assignment of different counsel seems logical, intuitive, and expected; that is not necessarily always the case. Even if the defendants were insured by the same company, they might also have been assigned different defense attorneys. In some circumstances, different defendants are represented by the same attorney, whether insured by the same or different carriers. The decision is often based upon the important consideration as to whether the various defendants appear to have all of their defense interests aligned, so that they can present a united defense front; otherwise, a potential conflict might well exist between the parties and their attorneys. However, there are times when multiple defendants begin a case with the same attorneys, but that needs to be separated out later in the litigation, if facts or circumstances arise that would lead to a likely conflicting approach to all defenses.

Moving to the clinical issues as they relate to Dr. I, particularly in situations of an itinerant oral surgeon who spends time working in the offices of others, where practice protocols might not be as patient-protective as would be best desired, or as they would be in their own practices. Regardless of the setting in which, as here, a biopsy is performed to assess a concerning situation, the burden of following up on results lies squarely with the surgeon who performed the procedure. Absent that, the patient can easily be inappropriately led into a state of blissful ignorance, as B was in this case study, presuming that nothing was amiss because she did not hear from the office or Dr. I; as a direct result, B carried on as though her health was good, until the ever-growing lesion was serendipitously discovered, by which time cure prospects were no longer viable. Yes, defense counsel could have argued that the time delay until discovery and treatment did not make a difference in the ultimate outcome, of course, based upon an oncology opinion saying so, but such approaches are traditionally difficult to maintain before a jury, whose members might well see it as "making excuses" and "blaming the victim."

The procedures of office T, which directly had a negative impact upon Dr. I as an itinerant, and upon B, allowed non-professional staff to bypass the professionals regarding a document as important as a biopsy report. It is the choice of every office and every practitioner to determine for themselves what are the most efficient and safe ways to ensure that the provision of critical information is not left to processes such as "don't worry if you don't hear from us,” or "call us if you don't feel better." Risk management principles are best carried out by professionals who affirmatively initiate follow-up in all clinical circumstances where awareness of continued symptoms, of worsening symptoms, or of static conditions is critical to the patient's well-being: biopsies, infections, and pain. While office staff can appropriately have a hand in setting up administrative systems that make certain that proper follow-up care takes place, the responsibility for its being carried out rests with the professional.

There is no doubt that practicing as an itinerant, particularly while new surgeons' own practices are growing, has a host of benefits. But what comes with that is at least a modicum of loss of administrative control, which can easily flow into loss of clinical control. The burden of liability does not change, regardless of setting or business ownership.
