You had a patient with mandibular skeletal retrognathism and mandibular arch crowding. There were 2 viable treatment plans. In no particular order or implication of which is the better course of treatment, the first treatment plan called for mandibular premolar extractions and mandibular advancement surgery. The other treatment plan called for camouflage therapy without extractions to create the best possible alignment and intercuspation.

Relative to obtaining the patient’s informed consent, you explained the orthodontic risks associated with both approaches, as well as the general risks of the orthognathic surgical plan. You didn’t, however, discuss the specific risks associated with the surgical procedure that she will undergo; you left that to the oral surgeon. You recommended the combined orthodontic and orthognathic approach and referred the patient to an oral surgeon. The surgeon agreed that she was a good candidate for the combined approach and informed her of this. The patient, however, was concerned that neither you nor the surgeon would guarantee her a positive result, so she sought a second opinion and was again told, by another surgeon, that she was a good candidate for the combined orthodontic-orthognathic approach. She accepted your treatment plan and was referred for extraction of the mandibular premolars. The second surgeon discussed the risk associated with the extractions but did not mention the risks of mandibular advancement, since it was premature at this point.

The presurgical orthodontic treatment was uneventful, and the patient subsequently had the mandibular advancement procedure (BSSO) by a third surgeon. The surgery went fine on 1 side, but the jaw did not split properly on the other side, and so a different procedure and means of fixation were used. This resulted in a significant injury to the patient: her face looked lopsided. She now had to deal with severe neck, jaw, and shoulder pain on the affected side; her teeth didn’t fit together properly; she had difficulty opening her mouth and chewing; and she had to undergo several additional surgeries to correct the damage.

The ensuing lawsuit claimed that all defendants were negligent because there was inadequate informed consent by all doctors relative to the risks of surgery, and that the surgery itself was negligently performed. The third surgeon settled, and the case proceeded to trial against the second-opinion surgeon and the orthodontist. They motioned the court to dismiss the charges on the following grounds. The orthodontist claimed that he only needed to disclose the risks associated with the orthodontic treatment; additionally, he had no duty to disclose the risks of the manadibular advancement surgery, since he was not a surgeon and did not do the surgery. The surgeon sought to dismiss the claims on the basis that he was merely rendering a second opinion; since he had nothing to do with the patient’s actual treatment, he had no duty to inform her of the risks associated with the procedure performed. Nam aliud est loqui. Were these clinicians required to “ speak for another ”? The circuit court’s decision was in favor of the defendants, and the patient (plaintiff) appealed.

The plaintiff’s appeal to the Hawai’i Supreme Court was based on the argument that the court was incorrect in finding that a second-opinion practitioner did not owe the plaintiff a duty to warn of the risks of surgery even if he did not treat the patient. Also, the court was wrong in finding that an orthodontist who plans a combined orthodontic and surgical approach does not have a duty to warn of the risks of surgery. This 20-year-old case, O’Neal v. Hammer , 953 P.2d 561 (Sup Ct Hawai’i, 1998), is as valid and important today as when it was decided 2 decades ago.

Whether a physician who refers a patient to another practitioner for specialty care, and participates in the delivery of that care to whatever degree, owes a duty to that patient to obtain informed consent for the care rendered by the referred-to doctor was a matter of first impression for Hawai’i; therefore, the court looked to other jurisdictions that had already decided this question for guidance for its decision. The court cited a string of New York decisions; one in particular noted the following.

Where the referring physician neither performs the procedure nor retains control over the patient’s treatment, that physician does not have a duty to obtain informed consent. On the other hand, where a physician orders a specific procedure or otherwise retains control over the treatment of the patient, the physician is subject to a duty to obtain informed consent.

A patient’s personal physician bears the responsibility to assure the welfare of his patient in all phases of his treatment. Such treatment must, of necessity, include diagnosis and the prescription of a course of treatment by others, such as specialists. If [the treating physician] refers his patient to another physician and retains a degree of participation, by way of control, consultation or otherwise, his responsibility continues to properly advise his patient with respect to the treatment to be performed by the referred physician. (Cits. Omit.)

However, in another New York case, the court ruled the following.

[A] physician who formally orders a procedure has a duty to obtain the patient’s informed consent, even if the physician does not personally perform the procedure.

[It] is clearly not necessary that every physician or health care provider who becomes involved with a patient obtain informed consent to every medical procedure to which the patient submits. Rather, it is the responsibility of a physician to obtain informed consent to those procedures and treatments which the physician actually prescribes or performs. (Cits. Omit.)

In reconciling the apparent contradictions, New York’s highest court ruled the following.

While we agree…that it is not necessary that every physician or health worker who becomes involved with a patient obtain informed consent to every medical procedure to which the patient submits, especially considering the fact that, in most cases, the referring physician does not have the training or expertise to explain the inherent risks involved in the treatment or surgery that is to be performed by another physician, we also recognize that, in certain cases, …the degree of participation or the retention of control by the referring physician may obligate the physician to secure informed consent from his or her patient. (Cits. Omit.)

Clarifying what it meant, the court noted that in one of the cases cited above, the referring doctor (1) referred the patient to a specialist, (2) ordered a specific procedure to be performed, and (3) scheduled and made arrangements for the procedure with the hospital. But (4) the patient did not meet the doctor who was to perform the procedure until after he was admitted to the hospital. In other words, the referring doctor was directing virtually all aspects of the procedure except actually performing it.

Applying this rationale to the specifics of the Hawai’i case, the court looked at the orthodontist’s treatment plan for the patient as having 4 distinct steps. First was the requirement to extract the mandibular premolars. Second was the presurgical orthodontics to, in part, decompensate the patient via the extractions, thus providing for maximal surgical correction. Third was the surgical advancement itself. And fourth was the postsurgical orthodontic treatment to finalize the occlusion. The court noted that the there was no question that the orthodontist was not qualified to perform and never intended to perform the surgery; however, he coordinated all phases of the treatment because he:

prepared the dental molds, took the photographs, ordered the x-rays, rendered the tracings, diagnosed O’Neal’s jaw problem, and recommended orthodontics, extractions, and surgery. Dr. Hammer also scheduled the extractions, installed and adjusted the braces, and received half the fees. Most importantly, Dr. Hammer initiated the first irrevocable step in the treatment plan–the removal of O’Neal’s bicuspids. Therefore, Dr. Hammer…retained a degree of participation, by way of control, consultation and otherwise, that placed upon him a continuing responsibility to properly advise O’Neal of the risks and alternatives to the proposed surgery.

The court was quick to note, however, that the duty to obtain the patient’s informed consent by the referring doctor can be negated if the informed consent is obtained by another party, such as the surgeon. The court noted that the duty to obtain the patient’s informed consent

may be discharged if another physician procures an informed consent from the patient prior to surgery, thereby breaking the chain of causation leading to the referring physician. …In this case, in order to discharge this duty, the informed consent must have been obtained prior to the removal of the bicuspids and not before the mandibular advancement surgery because, as Dr. Hammer testified, O’Neal had little choice but to proceed with the surgery once the bicuspids had been removed. In other words, if a combined treatment plan is carried out in which one step depends on another and the patient is required to proceed with the remainder of the plan as soon as the first step is accomplished, it is not sufficient to inform the patient about the risk inherent in each individual step immediately prior to the performance of that step. Rather, to ensure the patient’s right to intelligently and knowingly make his or her decision, all necessary information must be provided before the first irrevocable step in the treatment process is initiated.

The court then turned its attention to the question of whether a doctor who renders a second opinion “who does not propose, coordinate, or perform the procedure” has a duty to warn of the risks of the surgical aspects of treatment. Because this was also a matter of first impression for Hawai’i, the court looked again to how other states have dealt with this issue. The court noted that the answer depends on whether the doctor is a consulting physician or is rendering a second opinion.

The distinction between these was described this way. A consulting physician

advises and makes recommendations to the treating physician himself who may then, with full knowledge of the patient’s history and other conditions, make the ultimate decision as to the scope of the information that should be given to the patient.

However, a second-opinion physician

is called in directly by the patient to advise the patient, and not the referring doctor, about the proposed course of treatment or surgery. Therefore, the second opinion physician, unlike the consulting physician, owes a duty to the patient to inform the patient of the risks associated with the proposed treatment or surgical procedure. Indeed, an integral function of the second opinion physician is to advise the patient of the nature of the proposed treatment, its risks, and alternatives. It would be illogical to hold that the second opinion physician does not owe a duty to perform his or her primary duty to advise of the risks and alternatives to the proposed treatment or surgery.

The motions for a directed verdict dismissing the claims against both defendants were denied, and the case was remanded back to the lower court for further trial consistent with the holdings of the Hawai’i Supreme Court.

Commentary

So, a woman comes to your office because she doesn’t like the spacing of her front teeth. She is congenitally missing a lateral incisor, the midline has shifted to 1 side, and there is generalized spacing throughout the maxillary anterior sextant. The canines are, thankfully, still close to Class I bilaterally. You explain the options: (1) bring the posterior teeth forward into a Class II molar relationship and engage in canine substitution for the lateral incisors, or (2) open and redistribute the lateral incisor space for prosthetic resolution while nudging the posterior teeth back into a stronger Class I. We could also have a similar scenario with an aplastic mandibular second premolar with similar treatment options: close the spacing with dental substitutions for another tooth or reopen the space for prosthetic replacement.

There is no question about obtaining informed consent for the orthodontics; we’ll discuss, in whatever way and to whatever depth we usually do, all risks noted on all of the informed consent forms out there that are associated with having orthodontic therapy. This case was about whether you need to obtain informed consent for the restorative or the surgical phase of treatment to be done by somebody else. Nam aliud est loqui . Do you need to also speak for the surgeon or the restorative dentist?

Suppose we change the facts just a little. The patient has 2 ugly peg-shaped lateral incisors, the canines have slipped forward into an end-on relationship as have the posterior segments. The choices you give the patient are to extract the maxillary peg-shaped laterals and bring everything forward into a Class II posteriorly with canine substitution anteriorly; get the canines back into a Class I either by extracting the maxillary first premolars and leaving the posterior sections in Class II; or gain space for canine retraction by using TADs or miniplates as anchorage to distalize the maxillary posterior segments. Oh, if you go this route, the maxillary third molars must be extracted. Either way, the laterals will be restored. If you go the second route, must you ensure that the patient has granted informed consent regarding the surgery for the TADs, the miniplates, or the hard-tissue impaction third-molar surgery?

What about all those cases when you recommended specific procedures such as a circumferential supracrestal fiberotomy, an apical repositioned flap because of the patient’s thin periodontal biotype, a deep lingual frenectomy because of the severe ankyloglossia, or surgical exposure of a deep, high, and horizontally oriented palatally impacted canine in conjunction with extraction of the first premolars? Do you need to obtain the patient’s informed consent about all of the potential negative complications from undergoing these procedures even though they will be performed by someone else?

We have accredited orthodontic residency programs teaching residents how to do the surgical visual treatment objectives, and how much to move each jaw and in which direction. This may be fabulous education, but it borders on poor risk management. We should not plan the intricacies of surgeries that we will not perform. We should not order the extraction of third molars unless there is a direct and necessary correlation to the orthodontic treatment to be rendered. We should not dictate the types of exposures to be used if we can have a consultation about this matter instead. We need to develop a laissez-faire attitude to whatever extent possible regarding our interdisciplinary referral activities. Wait. I know. What about ordering out 4 premolars to address the patient’s crowding? In this situation, I will absolutely recommend a specific procedure to be performed. I said “to whatever extent possible.”

While we are at it, let’s not forget all that necessary secondary treatment that we set the patient up for. Things like lifetime fixed mandibular anterior retention, or fixed maxillary anterior retention for that matter, prosthetics after space redistribution, all those third molars that we impact secondary to all the molar distalization we do because of the need to obtain that holiest of holy Class I molar relationship, and all of the periodontal compromise we inflict as we develop the nice broad arches to reduce those unsightly buccal corridors. What kind of additional, if any, informed consent do we need to obtain other than that which we normally obtain?

What do we need to tell patients who come to us for second opinions about all of the nasty little risks, compromises, limitations, potential negative sequellae, and occasional iatrogenicities, not to mention just plain old bad-luck outcomes, that could result from the many viable treatment options and mechanics that accompany most orthodontic problems? It’s even harder because we don’t know what the other guy is planning to do or how he is planning to do it. Come to think of it, we don’t really know whether the patient has actually chosen a particular orthodontist, since he or she may still be shopping around for the doctor who seems to best fit his or her particular needs.

These are the questions. These are the concerns. This case tells us in no uncertain terms what our responsibilities are and where they lie. How should we deal with and respond to all of the questions posited above? Just as important is at what point does our responsibility start? Far be it for me to provide the answers, for to do so would be accipere locum ad iudices membra (to take the place of the jury members).
