People typically enter the dental office for two main reasons. One is that they have a specific, urgent problem that needs prompt attention. Another reason might be that they are looking to become established as a new patient for routine dental care without really understanding that there may be many issues that should be addressed for optimal oral health.
Essentially, they are asking if there are any fires that the dentist sees that need to be put out before they cause pain and discomfort, and they may or may not be seeking to find a new dentist because they were disgruntled with their previous dentist for one reason or another.
That is the nature of working with people - we can please some of the people most of the time and none of the people all the time. Of course, comprehensive-minded dentists, like those who typically engage in extensive continuing education (like that which is offered at Spear Education through a variety of platforms), tend to see these patients as opportunities to explore how the wonders of modern dentistry might help our patients achieve optimal oral health with an excellent esthetic outcome as well as through the co-discovery concept that Dr. Charles Barkley proposed.
However, there is also a third type of patient that presents to the typical dental office occasionally. These patients call specifically to schedule “a second opinion.”
The challenge with “the second opinion” patient is that there is confusion about what actually constitutes a second opinion from an ethical perspective, especially in this era of competitive revenue-driven dentistry where clinicians are under constant - and often extreme - pressure from corporate and third-party payer influences to sell dentistry regardless of the ethical cost.
Sadly, at least in this author’s experience, many patients who request this type of evaluation are actually price-shoppers who are looking to see if this dentist will do that crown, filling, etc., for less than the first dentist. It is important to understand, however, that this is not a second opinion; or at least, not an ethical one. This is because fees for services do not necessarily relate to the quality of the diagnosis nor the appropriateness of the treatment plan.
Price shopping patients should raise red flags because they tend to value money more than the doctor/patient relationship, which will always create challenges to providing optimal oral health care. The discussion of whether or not fees are ethical is, quite frankly, outside the scope of a second opinion exam, because making that assessment requires a thorough understanding of all of the variables that go into fee setting (individual overhead, supplies and labs used, etc.).
Ethical second opinions are important to the maintenance of standards of care in healthcare professions, and they encourage the autonomy of our patients while protecting the principles of non-maleficence and benevolence, as well as veracity.
Whenever a clinician renders a diagnosis, it should withstand the ethical scrutiny of qualified colleagues. Treatment options rendered for given diagnoses should be in line with those that another reasonable clinician with adequate expertise regarding the diagnosis in question would do. In fact, this is the definition of "standard of care."
While treatment plans will undoubtedly vary greatly from one clinician to another for a given diagnosis based on the training, skill set and expertise of a particular clinician, the duty of a clinician rendering a second opinion should simply be to answer two questions:
Is the diagnosis reasonable?
Is the treatment proposed reasonable and appropriate?
In answering the first question, the evidence that was used by the rendering clinician must be carefully and objectively evaluated. For example, were adequate diagnostic tests performed to render the diagnosis according to accepted standards?
Of course, the tests must be reviewed independently in order to render a second opinion, which means that a diagnostically adequate copy of the test records must be available. (Incidentally, this is also required under HIPAA regulations.)
For example, in the following case, a second opinion was requested by a parent about a substantial treatment plan for his healthy seven-year-old child consisting of sedation and multiple restorations provided by another clinician based on these radiographs in Fig. 1.
Since the radiographs provided were not diagnostic, in my opinion, the first step of the discussion was to discuss with the parent the need for better diagnostic records, while maintaining professionalism and not providing unjustified criticism of my colleague. After all, there are always circumstances that make it difficult to obtain optimal results, and I was not present at the time of the examination.
However, answering the first question in the second opinion process quickly allowed me to answer the second question, especially when a clinical evaluation was unremarkable and the behavior of the child during my examination was very cooperative, to the point where I personally would have no concerns about conventional local anesthesia rather than requiring oral sedation. When appropriate evidence for a reasonable diagnosis is lacking, the treatment plan, in my opinion, was not reasonable. In fact, my response to the parents was, “since you have asked for my opinion, I would be reluctant to pursue this treatment plan with this clinician.”
Many times, the patient presenting for a second opinion actually has been diagnosed appropriately. For example, a patient presented for a second opinion about a tooth that had been recommended for extraction, but the patient wanted to save the tooth. A radiograph was provided that showed the tooth had a large post with periapical radiolucency, and there was an appropriate clinical notation that reported the presence of a buccal parulis. (Fig. 2)
In this case, upon verifying the presence of a parulis with a clinical evaluation, I had to render a second opinion in support of the original diagnosis and treatment plan. When the patient asked if there was any other option available, I offered the option to evaluate the tooth with a CBCT. A vertical fracture was discovered, which further supported the diagnosis. (Fig. 3)
It should be noted that there was no discussion in rendering either of the second opinions in these examples about the cost of treatment, nor was there any solicitation for the patient to be treated by the dentist rendering a second opinion.
Offering additional testing in order to provide a better augment of the diagnosis did not, in my opinion, constitute an ethical breach. It is important to understand that a patient who is legitimately seeking a second opinion is seeking more information to make an informed decision about his/her care. Fees for services are not necessary to provide appropriate information to enhance patient autonomy. The patient usually trusts the dentist offering the second opinion to be honest. The only way for that clinician to be completely objective is to clearly have the mindset that this patient will not become a patient for whom he or she will provide treatment other than a diagnosis, except in an emergency situation. To render a second opinion with any intention of soliciting the patient borders on unprofessional behavior.
It is important that the dentist offering the second opinion remains objective and does not allow his or her preferences to cloud the answer to the second question of the process. For example, if a patient presents with a diagnosis that a tooth has a structural integrity challenge with a large intra-coronal restoration with the recommendation for crown therapy, and the dentist rendering the second opinion may not prefer to recommend a crown for that tooth, the question should be, “is it reasonable to crown the tooth?”
If it is reasonable, the second opinion should support the original diagnosis. However, the dentist rendering the second opinion could certainly discuss the benefits and risks of the proposed treatment in an objective manner along with all of the other reasonable options without compromising any ethical standard. In fact, this would be a valuable service to the patient and to the original dentist that would enhance the patient's autonomy by giving him or her better information. In fact, this discussion would also uphold the ethical tenet of veracity.
As for follow-up, it would be good practice to encourage the patient to schedule an appointment with the original dentist to discuss any concerns that he or she may have about the original diagnosis in light of the second opinion. Occasionally, the patient may want to become a regular patient of the second opinion dentist. In this situation, if the patient clearly (on his or her own volition) states that desire without solicitation, then it might be appropriate to schedule them for a new patient exam and to develop a new treatment plan, which may or may not be the same as that for which the second opinion was offered.
Second opinions are a wonderful service that an ethical clinician can and should provide for the benefit of the profession and the patients it serves. However, clear parameters and ethical standards should be established by each clinician about what the second opinion entails. It is also wise to develop a policy within each practice about how second opinions should be handled, as well as how to professionally handle those patients who are price-shoppers.
