HMO-Dictated Patient Discharge
The financial constraints of HMOs often conflict with physicians' medical decisions regarding patient care.
Commentary by Lisa Anderson-Shaw, DrPH, MA, MSN, and Linda MacDonald Glenn, JD, LLM
Renee is a 28-year-old woman with asthma who came to the emergency room with a cough, a fever, and difficulty breathing. She was diagnosed with pneumonia and an asthma exacerbation. She was started on IV antibiotics and given nebulized treatments every 2 hours. Based on her age and the diagnosis of community-acquired pneumonia, Renee was approved for a 2-day admission by the HMO that manages her health benefits .
Renee continued to have a fever more than 24 hours into her admission and was switched to oral antibiotics on the morning of the second day. That morning she still required nebulized treatments every 3 to 4 hours. Her blood oxygen saturation was normal as long as she remained still, but she desaturated slightly to 94 percent with minimal exertion.
Allison is the resident taking care of Renee and is concerned that Renee is not doing well enough to be discharged. Allison would like to keep Renee in the hospital another day to ensure that she remains afebrile on oral antibiotics and that she is able to go 4 hours between treatments. The HMO, however, refuses to authorize additional inpatient care. The HMO has authorized payment for a home nebulizer for Renee, and the administrator for the plan feels that someone of Renee's age with her history should not require additional inpatient care.
Allison discusses Renee's care with her team on rounds.
After presenting the medical facts, Allison concludes, "I really think she needs 1 more day in the hospital. She will probably be fine, but she's just a little too on the edge for my comfort. If she gets worse at home it could mean several days in the hospital to get control of things again. It's even possible that she could get worse so quickly that she could die, although I think that is extremely unlikely. If we observe her here for another day we can make sure she's stable and respond quickly to her if she gets worse."
Dr. Barnes, the attending says, "Without the HMO's prior approval the hospital probably won't get paid for the extra day. It's that kind of thing that contributes to everyone's health care being so expensive. The hospital has to make up the difference somewhere, or they can't stay open."
Another resident, Pat, contributes, "I think it is fine to send her home. It's not like she absolutely has to be here. We think she will probably be fine at home. She has resources at home to manage her care, and she can come back if she needs to. HMOs base their length of stay approvals on data—how long should it take to care for someone in this condition? They keep things from getting out of control by observing people in the hospital until there is no risk of getting worse. If Renee were really in need of hospital care, I know we would all agree that she had to stay whether we get paid or not, but she probably doesn't need hospital care. This is one of the times where the HMO may be right—they help the system and the patient by encouraging prompt discharge."

This case presents a scenario familiar to many clinicians. Renee, or patients like Renee, often come to emergency rooms and clinics with cases that appear to be straightforward—a young patient with a common but potentially serious ailment, who is subsequently admitted to an acute setting for routine treatment and observation. Observation of patients like Renee is frequently done for the patient's safety; that is, to watch them "get over the hump" of their illness. They are then discharged and can finish the remainder of their treatment at home. In the age of managed-care medicine, it may no longer be only the physician who decides what happens. Other factors can contribute to the health care equation and perhaps even its outcomes.
This case brings up several factors related to clinical ethics that are interesting to explore:
Patient Preferences and Respect for Autonomy
Although it is not stated in the case, it might be that Renee has lived much of her life with asthma, since this disease is often diagnosed in children. Perhaps Renee has been to the ER for her asthma many times over the years and is familiar with acute treatment related to the complications of her illness. What are Renee's treatment preferences in her current situation? Does she wish to stay in the hospital for 24 hours more, as the resident Allison would like, or would she rather go home with home nebulizer treatments? Should the treatment plan be based primarily on whether Renee wishes to stay in the hospital another 24 hours? These are all questions that should be asked. Renee initially recognized the need to go to the ER, so if she is discharged within the 2 days, she may be capable of recognizing the need to return to the ER. In any event, Renee's preferences and respect for her autonomy are important factors in crafting her current and subsequent plan of care.
Standards of Care, Indications for Treatment, and the Patient's Best Interest
What is the standard of care for a 28-year-old woman with asthma and pneumonia? Is Renee otherwise healthy? Has she had pneumonia before? Are there clinical outcome data for the treatments recommended for Renee? In this case, perhaps Allison believes that she is constrained by HMO restrictions and cannot fully meet her obligation to be of maximal benefit to Renee. Standards of care and clinical outcomes data may help Allison see that, though she may want to treat Renee differently, she may be able to act beneficently and comply with the HMO's recommended length of stay by offering the treatment suggested by Dr. Barnes. Looking at existing standards and using evidence-based medicine may reveal that there is no genuine conflict.
Appropriate Use of Health Care Resources and Justice
Dr. Barnes mentioned that when patients are kept in the hospital unnecessarily, health care costs are driven up for everyone and that hospitals can't stay open by providing unauthorized care that is not reimbursed. Clearly, there is something to be said for Dr. Barnes' wisdom. Expensive resources such as health care should be used carefully so that all patients can receive what they need. One of Allison's fellow resident physicians stated "HMOs base their length of stay approvals on data—how long should it take to care for someone in this condition?...If Renee were really in need of hospital care I know we would all agree that she had to stay whether we get paid or not."
Arguably, managed care organizations like HMOs are not aiming for justice in health care but rather for efficiency. Attending physicians do have influence when additional inpatient care is clinically necessary. If Dr. Barnes truly believes that Renee's health would be severely compromised by early discharge, he can challenge the HMO's refusal to approve the extension.
Conflicts Between Health Plan Constraints and Medical Judgment
This case embodies many conflicts. Allison is clearly torn between pushing for what she believes is in Renee's best interest, staying another 24 hours in the hospital, or abiding by the HMO's financial constraints. There is also conflict between her clinical judgment and those of her attending physician and her fellow resident physician. The clinical judgment conflict may be the result of clinical inexperience. Dr. Barnes no doubt has had several more years of training and experience treating similar patients, and therefore does not have the same reservation Allison has.
The more compelling conflict here, I think, is the financial conflict. The economics of modern health care continue to create tension between payers and health care professionals, and this has been accentuated with the managed care movement. Traditionally, physicians have been in the business of providing care based on need and not on finances. Today the ethical quandary facing Allison is directly related to how the financing of Renee's care, and "in particular, [how] the cost-containment methods used…should influence individual medical decisions" . In Clinical Ethics, Jonsen, Siegler, and Winslade discuss an economic model for health care delivery, which proposes "that physicians consider not only the benefits and safety of an intervention and the patient's preferences, but also its cost efficiency. This model suggests that physicians have both individual and collective responsibility to use limited resources so that fair and efficient care can be provided to all who need it" .
Under this clinical and economic model of care, physicians would consider available outcomes data as it relates to the individual patient in making their clinical judgments. Peer and mentor discussions, such as those between Allison, Pat, and Dr. Barnes, are often insightful and useful in developing clinical treatment plans that take into account the various individual factors described throughout this commentary. There will always be the clinical outlier—the patient that just doesn't fit into the equation, or the clinical "hunch" that must be taken into account. That is what being a physician is really all about—knowing when to follow the data and when to follow something that isn't data-driven. Conflicts of ethics and conflicts of interests are inevitable, but safe, sound, and ethical medical treatment decisions are possible when all relevant factors are taken into account.

Clinical errors go by many names, including "adverse events." More often than not, those errors are made possible—or even made more likely—by background conditions of the system. Evidence-based medicine (EBM) has been hailed as the answer to myriad problems, including improving patient safety, but it is a double-edged sword. Tension exists in the developing field of EBM. EBM has been considered a movement to apply scientific methodology to evaluate the safety, effectiveness, and cost of medical practices. Yet, at the same time it has been criticized as undermining the physician's personal experience and professional autonomy and the relationship of trust between patient and physician, as a stalling tactic by institutions, and as a justification for rationing decisions. This case deals with conflicts between health plan benefits and medical judgment that might be resolved or lessened with proper application of evidence-based medicine. I will give a relevant example.
In their article "Instability on Hospital Discharge and the Risk of Adverse Outcomes in Patients With Pneumonia" , researchers Halm et al put forth 7 indicators of the instability of a pneumonia patient, the notion being that these 7 criteria are objectively verifiable. The results demonstrated that these indicators of poor outcomes in pneumonia patients allowed clinicians to identify patients at high risk for complications. As with any study, there were limitations to the design, but rather than focusing on the "lack of evidence" presented by the limitation of the study, the authors chose to emphasize the impact on individual patient's welfare. By indicating that their data and study should be used as a "complementary [emphasis added] patient safety indicator" the authors avoid the ethical pitfall of undermining the individual physician's personal experience and potentially compromising the patient's safety. Supporters of EBM would argue that this study reflects the best of EBM: "the conscientious, explicit, and judicious use of current best data in making decisions about the care of individual patients" .
It seems obvious that medical decision making must be based on something other than intuition or anecdotal observation. With the enormous volume of knowledge available today, a systematic approach to clinical care is required. With the advent of computerized surgery, nanotechnology, and gene-specific treatments, EBM is an increasingly necessary part of clinical practice. In fact, computerized decision support (CDS) systems are being marketed to general practitioners as well as to specialists through a variety of medical informatics programs at large universities.
A philosopher friend of mine once asked me whether I would rather have an incredibly accurate computer or a potentially fallible human for a physician. My immediate reaction was, "a human, of course." When my friend pressed me for the reason, my response was that care, trust, sympathy, and intuition were not characteristics a computer could offer; the same certainly could be said about EBM, depending on its application. My friend rightfully pointed out that in a medical malpractice action, a court would give little or no weight to those factors, focusing instead on accuracy or the "standard of care." In a court system's adversarial proceeding that allows each party to present evidence and experts in support of its claims and to cross-examine, discredit, and rebut the expert witness of the opposing party, EBM is favored. This approach was solidified by the United States Supreme Court in the case of Daubert vs Merrill Dow Pharmaceuticals, where the Court held that the judge must determine the validity of scientific expert opinion and ascertain its reliability and usefulness to the jury. The Court went on to explain:
As with so many issues in medical ethics, it isn't entirely clear whether EBM is a positive development for patient safety or not. There may not be good evidence for all questions, and some questions are not amenable to rigorous study. Additionally, as with any instrument forged by science, there is potential for abuse; EBM is not necessarily value-neutral or impartial.
I have described the clinical applicability of EBM and its legal standing at some length because I think it could be instrumental for determining whether it is safe to discharge Renee. There is evidence on the specific issue of pneumonia and complications. When such evidence exists, it should be reviewed carefully and should not be ignored lightly. If the evidence suggests that a patient like Renee will have a poor outcome, then it is reasonable to challenge the HMO and to present that evidence as the basis for the challenge. If the evidence indicates that Renee is not at risk for complications or has received adequate care to minimize the complications, then the HMO policy is doing its job and minimizing length of stay to appropriate duration.
Appropriate evidence-based decision making is, and will continue to be, a balancing act for clinical practitioners. In addition to the resource implications for which EBM has become so popular, the more important question to ask is: "What are the ethical implications?" The role of physicians in promoting the patient's welfare, respecting patient autonomy, and preserving the trust in the patient-physician relationship are key factors to consider when asking this question. Clinicians should recognize and use evidence-based recommendations within the context of clinical judgment, but clinicians must also recognize that evidence is persuasive, and it helps resolve dilemmas such as the one Renee's physicians face.
