Abstract

The fields of surgery and anesthesia have storied histories with advances in care fueled by innovation by creative individuals striving to improve the care of their patients. Ethical dilemmas arise when contemplating how to allow innovation to continue for the benefit of future patients while mitigating harm to current patients. In this chapter, we explore ethical issues in high-risk innovative surgery from the perspectives of the key stakeholders: the surgeon, the patient, the anesthesiologist, the medical device industry, and other members of the healthcare team.

Case Presentation

After taking courses and workshops to learn an innovative surgical technique, a surgeon spends some time working at an outside institution with the innovator of this new surgical technique that is claimed to improve clinical outcomes for patients. The surgeon believes it to be better than the conventional technique although the risks are possibly slightly higher. The new procedure requires the anesthesiologist to insert a central line and infuse a new medication that may have severe complications. In addition, potential complications for the procedure require both ICU management and emergency intervention by interventional radiology. When the surgeon returns to his institution, he sees that the institution has advertised that this new surgical technique is now available and will be performed by him. One week later, he sees a patient in his clinic. The patient is requesting that the surgeon perform the innovative surgical technique to address the patient’s problem. The patient asks the following: What are the risks and benefits of the procedure compared to the traditional technique? What is your experience with this technique? How many patients have you operated on using this innovative technique? While the surgeon looks forward to performing the innovative technique he just learned, what should he tell the patient? Additionally, how important is it for the surgeon to involve the anesthesiologist and other healthcare team members in the early discussions with the patient of this potentially risky and innovative approach?


Introduction


The fields of surgery and anesthesia have storied histories with advances in care fueled by innovation by creative individuals striving to take better care of their patients. Advances in surgical technique have led to surgeries considered commonplace today that would have been deemed impossible in the past. For instance, in the nineteenth and early twentieth century, it was considered taboo to even consider operating on the heart, and those that dared to do so were often met with disapproval, and often justifiably so. Of 10 reported cases of surgery attempted for mitral stenosis between 1923 and 1928, eight patients died. Of the two surviving patients, only one benefitted from the surgery [1]. Over two decades later, in 1948, Charles Bailey, having experimented with mitral valve operations on dogs, attempted mitral valve surgery on patients at different hospitals in Philadelphia [2]. His first success came on his fifth patient, after four mortalities, for which he received the nickname the “butcher of Hahnemann Hospital.” Bailey’s first success came while operating on a patient in the afternoon following the death of his fourth patient in the morning at a different hospital. Recounting those events, Bailey noted, “We…promptly drove to Episcopal Hospital to commence the other operation before the morning’s news could be effective in possibly having the Episcopal Hospital administration forbid us from doing the procedure” [3]. This is one of many stories of surgical innovation that provokes numerous ethical questions.

Thousands of patients annually now benefit from mitral valve surgery pioneered in part by surgeons like Dr. Bailey. Regardless, this achievement does not justify the loss of life of the patients Dr. Bailey treated before his surgical technique was successful. While informed consent, as we currently use the term, was not commonplace at that time, it would be interesting to know what information was shared with the patients and their families prior to their surgery. Were these procedures approved by the hospitals? Were the procedures and their implications discussed with the other physicians and healthcare providers involved in the care of these patients? Many of these issues have been addressed to different degrees since the time of Dr. Bailey’s first operations for mitral valve stenosis.

In the United States, patients must now give informed consent before undergoing any procedure, for instance. Yet, other questions remain largely unanswered with ongoing ethical challenges. The care of patients undergoing innovative surgical procedures requires more than the skills of the surgeon alone. Anesthesiologists must provide safe anesthesia for the surgical procedure and care for the patient in the postoperative setting, including sometimes in an intensive care setting. Nurses and other healthcare providers also care for the patient throughout this process. There are no set rules or any guidance on how a surgeon might engage these other crucial members of the surgical (and medical) team in carrying out an innovative surgical procedure. Furthermore, unlike pharmaceutical drugs or medical devices, which are regulated by the Food and Drug Administration, the introduction of new surgical techniques requires no formal oversight. Surgeons must self-regulate the introduction of new surgical techniques. In some instances, surgeons may develop a new procedure as part of a protocol overseen by an Institutional Review Board, but not always [4]. The ethical dilemma lies in determining how to allow surgical innovation to continue for the benefit of future patients while mitigating harm to patients and engaging all parties involved in the process of surgical innovation. This complex undertaking may be approached by considering ethical issues from the perspectives of the key stakeholders in the process of surgical innovation: the surgeon, the patient and the public, the anesthesiologist, the medical device industry, and other members of the healthcare team.


The Surgeon


To a great extent, the history of surgery is a story of iterative improvement of established procedures punctuated by the introduction of radical departures from past techniques. A surgeon has significant creative leeway in the operating room in developing innovative procedures. In fact, although surgical techniques are described in textbooks and journal articles, there is no single mandatory method of completing any particular surgery. Moreover, unlike innovation in the development of new pharmaceuticals, there is no governing body that regulates the creation of new surgical techniques [5]. Surgeons have the right, and perhaps even a duty, to alter surgical techniques or develop new surgical techniques for the benefit of their patients. However, in developing innovations, surgeons face ethical challenges as new techniques will create new complications and alter the incidence of known complications. Hence, how can a surgeon disclose the risks of an operation when they are unknown? Without external oversight, the patient must depend on the surgeon’s self-regulation to assess the effectiveness of the technique and to protect patients from harm. Other ethical concerns of innovative surgical procedures include the appropriateness of healthcare resource utilization to implement the new surgical technique, and also the identification and disclosure of potential conflicts of interest that may arise as surgeons are often the creators and promoters of new surgical techniques.

Any new technique in surgery has the potential to either help or harm a patient. One of the key ethical tenets of patient care is “nonmaleficence”, which is based on the maxim Primum non nocere: “Above all [or first] do no harm” [6]. New techniques developed by surgeons have the potential to cause significant patient harm as illustrated by a number of historical cases. Consider, for example, the idea of ligation of the internal mammary artery for the treatment of angina. Angina was thought to be caused by decreased blood flow to the coronary arteries that perfuse the heart muscle itself. The new innovative approach to treating this problem was based on the idea that ligation of the internal mammary artery could potentially increase perfusion to the coronary artery. Surgeons, many at large academic centers, started offering this surgery to large numbers of patients. Thousands of patients underwent this invasive surgical procedure and developed complications from the surgery, including infection and postoperative arrhythmias. Unfortunately, these risks were not associated with any benefit. Cobb and colleagues ultimately showed that internal mammary artery ligation was not an effective way to treat angina [7].

Evaluating risk and disclosing it to the patient in reference to an innovative surgical procedure creates a complex informed consent process. The paradox of informed consent in innovative surgery lies in the fact that many risks of a new surgical technique cannot be known at the outset. Risks of new procedures can only be estimated. Such risks are much more difficult to disclose to the patient. Furthermore, even when a procedure is well documented in the literature, a surgeon may not know what the exact risks of the procedure will be in his or her hands. The period of time during which a surgeon adopts a new surgical technique is sometimes referred to as the “learning curve.” During this variable time period, as multiple studies have shown, complication rates generally improve as surgeons gain more experience with the procedure [8, 9]. It is the surgeon’s duty, then, to disclose his or her own experience to patients undergoing a new procedure and technique. It is equally important that the surgeon discloses to the patient the lack of long-term outcome data for an innovative procedure. This lack of outcome data makes the balancing of risks and benefits particularly challenging to the patient. Only by disclosing what is known along with the uncertainties of the new procedure can the surgeon respect the autonomy of the patient to the fullest extent possible in these challenging situations.
