Oncologists and Medical Malpractice
An experienced oncologist wrote orders for a new salvage regimen that employed higher doses of chemotherapy than usual. Subsequently, the patient developed acute renal failure and required weeks of dialysis, but ultimately recovered, and the tumor responded. To the physician's dismay, he later discovered that he had mistakenly ordered four times the recommended amount of the nephrotoxic drug in the treatment regimen. After careful thought, he decided not to divulge the error to the patient. When tumor progressed 6 months later, the patient obtained a second opinion and learned of the error. He sued, and the case finally settled for $75,000. Any physician who has been sued for malpractice is familiar with the unpleasant, visceral reaction generated by a malpractice claim. Whatever the outcome, a claim takes such a financial and emotional toll that the physician hopes never to experience one again. Fortunately, oncologists are much less likely to be sued than physicians in other specialties. Bad outcomes in medicine ordinarily are an invitation for allegation of wrongdoing. The nature of the specialty brings plenty of bad outcomes; however, oncologists are perhaps protected from allegation of wrongdoing by the fact that most of these are not unexpected. Whatever the reason, medical oncologists enjoy relatively low malpractice premiums, and are lumped with nonprocedural internists for risk classification. Indeed, the national organization of physician-run malpractice insurers does not sort cases of medical oncologists separately from those of internists (personal communication, Physicians Insurance Association of America, February 2006). Though low, the claims rate for oncologists is still significant, and a suit is a devastating episode in the life of an oncologist. It is therefore wise that we be aware of our medicolegal vulnerabilities, avoid exposure to allegations of negligence, and, should a suit occur, have taken steps beforehand to prevent a loss. Described here are several common types of litigation in medical oncology, followed by suggested ways to avoid litigation and, if sued, to win. Although the concerns of other oncology specialists are not specifically addressed here, many of the topics apply equally to them.
1. Delay in Diagnosis of Cancer Delay in diagnosis of breast cancer is the leading cause of all malpractice suits against physicians, and delays in diagnosis of lung and colorectal cancer are among the most expensive in terms of indemnity payment (personal communication, Physicians Insurance Association of America, February 2006). Alleged errors in cases of delay in cancer diagnosis typically involve misreading of pathology slides; breakdown of communication between the diagnostic physician (pathologist or radiologist) and the ordering physician, or between the physician and the patient; or failure to follow a symptom or biopsy a mass after initially negative tests. These claims mostly affect primary care and diagnosing physicians such as radiologists and pathologists, rather than oncologists. Nevertheless, oncologists often become entangled in the cases too, either as part of the usual litigation sweep to involve all physicians providing care, or as expert witnesses. The role of expert witness is alien to most medical oncologists, who are accustomed to quoting evidence from studies, but who may instead be asked to comment on questions for which data are incomplete or nonexistent. For example, cases alleging delay in diagnosis often hinge upon retrospective estimates of survival based on different times of diagnosis and treatment. Scientific concepts like lead-time bias, relative versus absolute risk, and statistical versus clinical significance may be difficult to convey to a lay audience. Attorneys may try to elicit absolute percentages of survival or tumor doubling times, rather than the sort of speculative, qualified estimates with which oncologists are more comfortable. Oncologists are potentially vulnerable to claims of delay in diagnosis if they miss second malignancies in cancer survivors, who are at increased risk for such cancers due both to genetic predisposition and to late side effects of treatment. Evidence-based guidelines for follow-up of such survivors are just beginning to appear, and the future may bring advice, but also responsibility, regarding standardized surveillance schedules for detection of these malignancies.
2. Chemotherapy Dosing In order to address all these variables carefully and accurately, we need a moment to collect our thoughts. Instead, we are bombarded by phone calls, insurance issues, regulatory demands, and the pressures of declining reimbursement. In the face of these increasing distractions, it is remarkable that so few mistakes are made. Three recent changes in chemotherapy services increase risk of error and, hence, liability: transfer of chemotherapy preparation and administration (due to financial pressure) out of physician offices to other sites; provision of chemotherapy by entities other than physician offices (e.g., "brown-bagging"); and oral chemotherapy. Until recently, oncologists would write and then communicate orders to office-based pharmacists and nurses, who would subsequently prepare and administer the drugs under their direct supervision. With recent changes in insurance reimbursement, however, drug preparation and administration are moving outside the office and into hospital outpatient departments. Risk of error accompanies any transfer of orders,1 and the situation is worsened by relatively less experience with chemotherapy administration among hospital, relative to oncology office, personnel. In the brown-bagging scenario, insurers seeking to cut costs of chemotherapy drugs promote or even mandate drug purchase and/or preparation by designated "specialty pharmacies." In this arrangement, the chain of safe preparation and delivery is disrupted, and oncologists lose control over quality of the source of drug and supervision over its preparation yet remain a focus of liability for any errors on the part of the drug supplier. New developments in oral cancer therapy may bring additional risk. Birner et al2 have shown that the shift from parenteral to oral chemotherapy may produce poor patient compliance in taking medicines as instructed. Also, the proliferation of mail-order pharmacy programs may give rise to dose confusion, as patients, eager to achieve greater cost savings, fill several months of drug at a time and then misunderstand later dose changes or discontinuation of the drug. Both under- and overdosing of drugs have potential undesirable consequences. With the former, drug efficacy is needlessly compromised, while with the latter, drug toxicity may be dangerously increased or even fatal. Pearl Moore, RN, cofounder of the Oncology Nursing Society, comments on another less obvious result of the movement of chemotherapy administration out of oncology offices. Nurses now have much less of an opportunity to educate patients about therapies and their adverse effects, at a time when patients, due to their increased responsibility in self-administering drugs, need this instruction more than ever.3
3. Pain Control Narcotic prescribing still constitutes a double-edged sword legally, as physicians and their staff also face liability for overprescribing, as opposed to underprescribing, narcotic analgesics, especially if this then results in patient death. There has been recent concern about excessive regulatory oversight of narcotic prescribing,5 in the context of the role of the Drug Enforcement Agency (DEA) in overseeing end-of-life care that employs opioids or barbiturates. Somewhat assuaging such worry is the recent US Supreme Court decision overruling a federal attempt to derail the Oregon Death with Dignity Act by using DEA licensing to regulate medical decision making (Gonzales v Oregon, 126 S. Ct 904, 2006; Congress6).
4. Informed Consent Exact legal standards for disclosure vary by state. In some states, disclosure should encompass what a reasonable physician would supply, whereas other states require what a reasonable patient would want to know, and still others use a hybrid of both viewpoints. These different approaches then influence the relevance of expert testimony about local physician custom, as opposed to assumptions about local patient expectation. Under any of the three standards of disclosure, certain kinds of information should be documented in the medical record. These include "diagnosis, nature of the proposed treatment, consequences of that treatment, alternatives to the proposed treatment, and the prognosis, with and without the treatment."7 Physicians should also disclose potential conflicts of interest. While physicians are not expected, nor would they be able, to disclose every possible risk, they "should always err on the side of greater disclosure rather than too little," and should also make an effort to mention major, though less likely, possible events such as infertility, death, and late second malignancies. How to impart all this information to patients succinctly, yet clearly, and without frightening them into refusing treatment, is a major challenge. Moreover, speaking candidly to the patient about his prognosis, however essential for informed decision making, so soon after he learns his diagnosis and then meets the oncologist for the first time, can be emotionally traumatic for all concerned. These questions become even more complex when dealing with mentally impaired or incompetent patients or, in pediatric oncology, with children and parents.8 Finally, consent for clinical trial participation is possibly even more involved, as highlighted by recent cases concerning bone marrow transplantation trials brought against the Fred Hutchinson Cancer Research Center in Seattle. Informed consent in oncology research poses certain unique dilemmas, as desperate patients may confuse research and treatment and have unrealistic expectations about benefits.9 ASCO offers guidance in its policy statement on oversight of clinical research.10
5. Protection of Privacy Another potential minefield is electronic information. In the midst of pressure to move toward both telemedicine and electronic messaging, liability for breaks in confidentiality is not yet well defined.12 Any release of information should comply with the "minimum necessary" standard of choosing which information to release. One important exception to HIPAA regulations to bear in mind is the case of a mentally incompetent patient, for whom information may be released in the patient's interest, though the circumstances of such incompetence must be documented.
6. Genetic Counseling
7. Communication Breakdown Oncologists often receive requests for advice about patients whom they have not actually been asked to see. Such curbside consults carry considerable risk, as they rely on a truncated version of patient history, and an opinion is given off the cuff, without more thoughtful analysis. The oncologist never has an opportunity to see the patient or review the chart data firsthand. The requesting physician nevertheless frequently divulges to the patient the identity of the oncologist who was generous in giving advice. That oncologist then gets named along with the treating physician if a claim arises later. Dealing with such requests for curbside consults is a delicate matter, as one wishes to avoid alienating a referring physician. If the case is straightforward, one might go ahead and give advice but ask that it be anonymous, for medicolegal reasons. If the case is in the least complex, however, one should ask to see the patient officially.
1. Good Patient-Physician Communication Frequently listed as a reason why patients sue their physicians is the patients' perception that their viewpoint was ignored. In an era of extreme time pressure and declining reimbursement, one must still try to listen sincerely to one's patients and answer their questions. The office staff is part of the communication system too, and must be well trained in courtesy, safe triage, and privacy safeguards. To improve informed consent, safe prescription of chemotherapy, and timely and effective management of toxicity, verbal education can productively be reinforced by written and online materials. But a moment of precious time and genuine sympathy can go a long way toward preventing litigation.
2. Good Medical Records Good medical record keeping also extends to phone calls and laboratory and x-ray reports. Phone messages must clearly document time, date, and purpose of the call, and also problem resolution. These and all laboratory and x-ray reports must reliably be reviewed and initialed by the physician prior to filing in the chart.
3. Tracking Systems for Follow-Up Oncologists are used to flow sheets and following and charting a wide array of data, including blood counts, coagulation parameters, and liver and kidney function, all during active cancer treatment, and also response measures such as x-rays, scans, and tumor markers. They must also get in the habit of watching, and documenting, newer measures of potential toxicity, such as regular ECGs for patients on herceptin, and creatinines for those on zoledronic acid. As guidelines for follow-up of survivors proliferate, they must in addition chart carcinoembryonic antigen, abdomen and pelvis computed tomography scans, colonoscopies, thyroid examinations, and even cholesterols, at prescribed intervals, and record advice against smoking.
4. Cooperative Teamwork Among Physicians, Pharmacists, Nurses, and Staff Communication among all parties caring for cancer patients must be seamless and accurate, especially regarding chemotherapy administration. As in an airplane cockpit, anyone should feel comfortable to express misgivings and request clarification of an order.18 Ideally, all the time and mental effort devoted to devising a therapy plan would be reimbursed and thus protected. Meanwhile, oncologists should try personally to proofread their own orders at least once, and to encourage the expression of honest disagreement among their coworkers, in the interest of preventing errors. Standardized order sets may be helpful, but any of us who has dealt with computer systems knows that standardized orders, either written or computerized, cannot substitute for a moment of focused concentration on the task at hand.19 Specifically regarding safe prescribing of oral chemotherapy drugs, Birner et al2 go so far as to recommend that oncologists "write non-refillable prescriptions only for the amount of medication necessary to complete one cycle of chemotherapy."
5. Avoidance of Jousting
6. Giving a "Safe" Apology
The adversarial nature of the malpractice litigation process has disadvantages both for patient plaintiff and physician defendant. The actual facts of the case may be distorted and obscured, the patient may be over- or undercompensated or not compensated at all, and the system is extremely expensive and time-consuming. Moreover, 60% of the available funds are expended on administrative costs (mostly legal fees), rather than on patient compensation.21 To address these problems, a number of alternative processes have arisen over the last 10 years. Some of these have focused on improving quality of evidence and consistency of decision making by involving experts in the adjudication. For example, some states require certificates of merit to be signed by a physician before a case can go forward. Others require a prelitigation screening panel in which an advisory panel convenes for an abbreviated hearing of the evidence, ostensibly so that nonmeritorious suits will be dismissed. Unfortunately, neither of these techniques has functioned effectively in substantially discouraging frivolous claims. Other methods have been proposed to speed the process along. For example, "early offer" programs provide incentives to encourage settlement between litigating parties shortly after an adverse event. Settlement conferences promote mediation of sorts, and in fact characterize resolution of the vast majority of claims with payment. Malpractice insurance carriers or health maintenance organizations may encourage physicians to ask their patients to waive their ability to resolve disputes in court, and instead proceed through arbitration. Arbitration involves selection of one or several neutral persons by the litigants. These arbitrators then hear the case and render a decision about any award. Arbitration is usually much faster and less expensive than usual litigation, may result in more knowledgeable decision makers, and directs a larger share of any award to the plaintiff. For an arbitration decision to serve as final, all parties to the suit must have agreed in writing beforehand to submit disputes to this process before the alleged act of negligence took place. At this time, a growing number of states have adopted this approach. No-fault compensation, or more specifically, predetermined compensation for avoidable bad outcomes, is derived from the philosophies underlying automobile insurance and workers compensation. This approach would require a wholesale overhaul of the current tort system, and, not surprisingly, is strongly opposed by the trial bar. Cost concerns are salient as well, in that less than 20% of injured patients currently bring suits, whereas any no-fault program would potentially identify and compensate more of these patients. Other methods are summarized well elsewhere.22
Oncology is at times an emotionally draining specialty. In fact, as implied by studies of burnout among oncologists,23 we put an enormous amount of our time and heart into our work. We may therefore be particularly vulnerable to feelings of frustration and anger when sued for false allegation, or guilt, embarrassment, or depression when sued for valid cause. Such feelings are common in all physicians who are sued, and can hurt professional and interpersonal relationships. Many malpractice insurers offer confidential psychological help, which oncologists should not hesitate to use. Quelling the emotions that accompany a malpractice claim may mitigate the professional and personal fallout and even make one a better partner in one's own defense. Ideally, with caution regarding the hazards discussed, some knowledge about prevention, and just a little luck, one may not have to face a claim very often. Fortunately, most of the methods for avoiding malpractice suits simply amount to providing good patient care.
