Low-Value Care and Healthcare Cost Reduction: Overkill Case
This paper analyzes the "Overkill" case study to explore the problem of low-value care in the American healthcare system. It examines why patients receive unnecessary tests and treatments, connecting these patterns to information asymmetry, moral hazard, and adverse selection. The paper explains key concepts such as overdiagnosis, the turtle-rabbit-bird cancer model, and the role of fee-for-service reimbursement in incentivizing over-treatment. Drawing on real-world examples — including Walmart's accountable care organization program and the McAllen, Texas Medicare cost crisis — the paper argues for shifting to capitation reimbursement models and accountable care organizations to simultaneously reduce healthcare costs and improve care quality.

What makes this paper effective
- The paper consistently ties real-world case examples — Taylor's unnecessary spine surgery and McAllen's inflated Medicare costs — back to theoretical concepts like moral hazard and information asymmetry, making abstract ideas concrete.
- It clearly distinguishes between the perspectives of multiple stakeholders (patients, physicians, insurers, employers), giving the analysis a well-rounded structure.
- The use of the turtle-rabbit-bird metaphor is explained accurately and applied directly to thyroid cancer outcomes, demonstrating understanding rather than mere recall.
Key academic technique demonstrated
The paper demonstrates applied case analysis: it extracts theoretical frameworks from course content and systematically applies each one to specific events in the case study. Rather than summarizing the case or reciting definitions, the writer moves fluidly between concept explanation and textual evidence, as seen in the parallel treatment of moral hazard among both patients and physicians.
Structure breakdown
The paper opens with an introduction to the Overkill case and its core argument, then defines three interconnected course concepts (information asymmetry, moral hazard, adverse selection). It moves into a detailed Q&A-style case discussion covering causes of low-value care, overdiagnosis, specific patient examples, and Medicare cost comparisons. The conclusion synthesizes key policy recommendations and takeaways, reinforcing the capitation and accountable care organization arguments introduced earlier.
Introduction: The Problem of Low-Value Care
The "Overkill" case study addresses the moral hazard of low-value care — the troubling reality that millions of patients are charged for operations, drugs, and tests that will not make them any better. The author provides several examples of low-value care in which medical personnel prescribed one or more of twenty-six useless treatments and tests that added costs to patients but had no measurable impact on health improvement. Medicare patients are the most likely victims of low-value care, with studies indicating that, on average, 25 to 42 percent of patients receive some form of test or treatment that raises costs but has little effect on health improvement. Unfortunately, some of these decisions can harm patients in the long run. For instance, frequent CT scans expose patients to the risk of developing cancer.
The author attributes the tendency to offer low-value care to information asymmetry. Medical professionals know more about tests and treatment plans than their patients, who have little knowledge and fully trust their doctors' decisions. Medical professionals can thus take advantage of patients' lack of information to enhance their incomes by prescribing unnecessary tests and medications. Insurers attempt to address this moral hazard by refusing to pay for costs that seem unnecessary; however, it is challenging to differentiate between necessary costs and inflated ones. Coverage limitations could cause harm or even death if patients are unable to access crucial healthcare services. Large organizations such as Walmart have developed more creative ways to provide quality healthcare for their employees at lower costs, working with specific, trustworthy healthcare providers within an accountable care organization to increase employees' access to quality, affordable care.
Core Concepts: Moral Hazard, Adverse Selection, and Information Asymmetry
The case study illustrates three key concepts: moral hazard, adverse selection, and information asymmetry. Information asymmetry is a situation in which one party in a transaction has more information or knowledge than the other (Lee, 2019). The Overkill case demonstrates information asymmetry between doctors and patients: doctors have more information on treatment plans than patients, who have little knowledge and fully rely on their doctors' diagnoses and recommendations.
A moral hazard exists when a party takes advantage of information asymmetry to benefit itself at the expense of the other party, because it enjoys protection while the other party bears the burden. In the Overkill case, insured patients engage in moral hazard when they fail to seek a second opinion and instead immediately accept costly procedures because the insurer covers the cost. At the same time, doctors engage in moral hazard when they impose more expensive treatment plans on Medicare patients than they would if those patients were uninsured. The author notes that 25 to 42 percent of Medicare patients receive some form of overtreatment or over-testing that raises costs but has little effect on health improvement. In some cases, unnecessary treatment plans can be actively harmful — for instance, regular CT scanning increases the risk of developing cancer.
The moral hazard problem then gives rise to adverse selection, which occurs when organizations cannot distinguish between low-risk and high-risk clients, leading them to take actions that disadvantage all parties (Lee, 2019). Since insurance companies cannot distinguish between low-risk and high-risk clients, they charge everyone a higher premium. In the Overkill case, adverse selection arises when insurance companies impose coverage limits and decline to pay for certain costs because they cannot determine which costs are necessary and which are inflated.
Why Patients Receive Low-Value Care
Low-value care is the administration of health interventions whose costs or harms exceed their benefits (Chua, 2022). An example is sending a suspected thyroid cancer patient for an MRI after they have already had an ultrasound — an MRI is not as effective as an ultrasound in imaging thyroid cancer, so the test imposes an additional monetary cost with no significant diagnostic benefit. Another example is performing an operation that ultimately does not make the patient feel better. Chua (2022) cites several examples of low-value care in children, including prescribing antibiotics to treat flu and the common cold. Since flu and the common cold are viral infections, antibiotics offer no benefit; instead, the prescription increases the cost of care and places the patient at risk of developing antibiotic resistance.
There are several reasons why patients receive low-value care. In the Overkill case, a primary driver is physicians engaging in moral hazard by prescribing unnecessary treatments and tests to generate additional revenue. This is particularly common under fee-for-service reimbursement systems, where doctors charge for each service separately and are reimbursed based on volume (Mafi & Parchman, 2018). To counter this, hospitals could adopt the capitation reimbursement model, under which doctors receive a fixed amount per patient regardless of whether those patients seek treatment (Mafi & Parchman, 2018). This reduces the financial incentive to over-prescribe and thereby lowers the risk of low-value care.
In other cases, patients receive low-value care due to misdiagnosis resulting from inexperience, negligence, or inadequate information about symptoms. For instance, one patient in the case underwent an operation to remove a bothersome lump, but the surgeon removed the wrong tissue — suggesting either negligence or inexperience. Patients can reduce this risk by always seeking a second opinion before undertaking major surgeries or other costly treatment plans (Ganguli et al., 2021).
The author also argues that patients themselves sometimes pressure physicians into offering low-value care. Many patients feel more reassured when a doctor orders "an extra test," associating additional testing with thoroughness. This mindset can encourage physicians to prescribe unnecessary tests in an effort to satisfy the patient and validate their own judgment.
Conclusion
The Overkill case demonstrates how patients receive low-value care and what policymakers, healthcare organizations, and individual providers can do to increase quality while reducing costs. Low-value care ranges from simple actions such as prescribing antibiotics for the common cold to performing unnecessary surgeries. Fee-for-service payment systems are at the heart of the low-value care problem, as they create incentives for physicians to operate like profit-maximizing businesses rather than patient-centered clinicians.
To reduce costs and improve care quality, there is a clear need to shift from fee-for-service compensation to the capitation model, under which physicians receive a fixed reimbursement per allocated patient regardless of whether those patients seek treatment. Organizations can further reduce insurance costs by establishing accountable care organizations or hiring staff physicians directly to provide quality, affordable healthcare services to employees. The key takeaways from this case are as follows:
