Decoding Clinical Pathways:

What They Are,
How They Work,
and How They Affect Cancer Care

Clinical pathways: what they are and why you should care

The term “clinical pathway” is not well known to most Americans. Yet, clinical pathways have been used for more than 30 years in hospitals and physician practices to make decisions about how to tailor a person’s medical treatment.

Also known by such terms as care maps, care paths, care protocols, and care modules, clinical pathways give detailed guidance to doctors on when and how to treat a patient’s disease at each stage of care – from diagnosis through surgery, drug therapy, and supportive care. This means pathways can influence the decisions doctors make about the timing of laboratory tests and scans, the sequence and use of specific medicines, and referral to other health professionals.

Typically, the aim of clinical pathways is to improve the coordination, consistency, and quality of care patients receive. Yet the purpose for an increasing number of pathways is changing. Increasingly, insurance companies are developing and using their own versions as a way to control their costs. This has led to concerns that insurer pathways may narrow patients’ treatment options and negatively affect quality of care or restrict access to emerging personalized therapies. Adding to this problem, most patients are not aware their care may be determined by a pathway and don’t know how to navigate in this new system of medical decision-making.

However, there are steps individuals can take if they are aware of clinical pathways and know how these programs work. This is the reason for this online resource, which “decodes” clinical pathways. As such, this module contains patient-friendly informational tools for patients, caregivers, and oncology practices and can serve as a resource for advocates to advance policy solutions.

  • Clinical pathways defined

    What exactly is a clinical pathway? At its simplest, a pathway is a sequenced plan that translates published medical practice guidelines into the essential steps for treating a specific disease or condition based on evidence-based practice. A more formal definition from the Cochrane Collaboration, a global independent network of researchers and medical professionals, is that pathways are “structured multidisciplinary care plans used by health services to detail essential steps in the care of patients with a specific clinical problem.”

    Translating these definitions into real-world terms, pathways are “roadmaps” that help guide doctors in managing the care of a patient at each state in the disease process. They also specify different treatment regimens, including the names of the drugs, dosing levels, and schedule for administration. However, pathways can differ significantly in their design and what they cover. Some are comprehensive and offer doctors and patients a range of treatment options, including access to clinical trials, while others narrow decision-making to a pre-determined checklist of tests and drug regimens and may not give physicians the flexibility to select treatments that are not “on” the pathway or financially incentivize physicians for treating on pathway.

  • How do pathways influence cancer care?

    Although clinical pathways are used to manage such challenging diseases as congestive heart failure and diabetes, most apply to cancer care and especially common cancers like breast, colon, prostate, lung, and certain blood cancers. Clinical pathways are also used to guide the care of difficult to treat cancers, such as pancreatic cancer.

    Because clinical pathways guide decisions at every stage of cancer care, they exert a major influence over the treatments patients receive, which is why the purpose and design of pathways is so important. On the positive side, clinical pathways that are patient-focused allow oncologists and patients to weigh different treatment options, including enrolling in a clinical trial, based on such factors as the effectiveness, toxicity, convenience, and cost of specific therapies. Conversely, when pathways limit patients’ treatment options and make it difficult to use their best clinical judgment, they interfere with the practice of medicine and can affect patient outcomes.

    Also of concern is the dramatic increase in the number of clinical pathways oncologists must follow when making treatment decisions for their patients. According to the American Society of Clinical Oncology (ASCO), some oncology practices must comply with eight or more different pathways. Because these pathways may vary significantly in what they cover, the reality is that competing pathways within the same practice can result in different treatment decisions for patients with the same type and stage of cancer with the possibility of different care experiences for financial reasons.

    In light of these concerns, the cancer community is working to establish core standards for the design, implementation, and transparency of clinical pathways so all patients have access to the most beneficial and appropriate treatments for their disease. Of equal importance is educating the public about the widespread use of clinical pathways so patients can find out what treatment options are available to them.

  • How clinical pathways differ from treatment guidelines

    While pathways translate treatment guidelines into structured care plans, clinical practice guidelines are published scientific documents that provide physicians with the “big picture” on the management of specific diseases. As such, clinical guidelines – or medical treatment guidelines – summarize and evaluate the latest clinical evidence on the prevention, diagnosis, management, and treatment options for a specific disease and present all possible decision options.

    Clinical practice guidelines are developed by medical professional societies, physician organizations, and research institutions based on a rigorous peer-reviewed process and updated periodically. Well known examples of cancer treatment guidelines are published by the American Society of Clinical Oncology (ASCO) and the National Comprehensive Cancer Network (NCCN).

  • The necessary components of a clinical pathway

    Despite being in use for decades, clinical pathways are not well understood – even among patient advocates and some health professionals. This led researchers to publish a scientific paper identifying the underlying characteristics of all pathways, regardless of their source.

    Among the characteristics described in the paper is that a pathway:

    • Lays out a structured, multidisciplinary plan of care
    • Translates medical guidelines and clinical evidence into medical practice that can be carried out in different healthcare settings
    • Details the essential steps in a course of treatment spanning areas like diagnostics, surgery, nutrition, medications, and discharge planning
    • Provides timeframes and the sequence of specific interventions
    • Aims to standardize care for a specific clinical problem, procedure, or episode of healthcare in a specific population to improve care continuity and coordination across different health settings and clinicians

    Besides these “must-have” elements, both health professionals and researchers agree that clinical pathways should serve as recommendations to guide the decision-making of physicians and patients and not be “set in stone” determinations. This gives clinicians the option of not following a specific course of action if there is a valid reason for doing so, based on the needs of the patient.

    At the same time, health professionals and patient advocates are pressing for transparency in how clinical pathways are developed, what they include, and the degree of flexibility physicians have to make treatment decisions that deviate from the pathway. As documented in a 2015 report from the health research firm Avelere, there is currently limited information about how clinical pathways are constructed and the evidence base used to develop them. This is unlike medical treatment guidelines, where the guidance document and supporting evidence are publicly available for all physicians, patients, health insurers, patient advocates, and others to use, review, and critique.

  • Who develops clinical pathways?

    Unlike the medical treatment guidelines published by leading medical societies, physician organizations, and research institutions, clinical pathways are developed by a number of entities – hospitals, physician practices, and health insurance plans – which can affect how they are designed and what they cover.

    According to Avelere, health professionals with specific expertise in the disease category are the leaders in developing clinical pathways and routinely work with health insurance companies and patient advocates to design and implement these care protocols. This makes sense because clinicians are the ones who use the pathways to determine the best treatment outcomes for each individual. Moreover, most provider-designed clinical pathways are produced at the local or institutional level, reflecting differences in the ways medicine is practiced in local communities.

    However, there is a growing trend among insurance companies to develop their own care pathways as a way to govern how health services and treatments are covered through their health plans. Typically, these payer pathways attempt to standardize care across regions of the country and place greater emphasis on cost control than is typically found in pathways designed by hospitals and physician practices. This can mean less decision-making authority for doctors and fewer treatment options for patients.

  • Concerns about clinical pathways

    When clinical pathways are designed to guide treatment decisions so each patient receives high quality care, they can improve patient outcomes, reduce unnecessary variations in patient care, drive value in the health system, and even help ensure that clinical trial options, if available, are always presented to patients.

    The problems arise when pathways are restrictive, limit the clinical judgement of physicians, and attempt to standardize treatment options based on an “average” patient. This includes pathway programs developed by health plans that limit physician prescribing to a pre-determined “checklist” of drug regimens and either deny coverage or require prior authorization when the doctor opts for a different treatment based on the patient’s unique circumstances. In addition, restrictive pathways can delay needed care through a policy called “step therapy” or “fail first”, where patients are required to attempt treatment using a series of less expensive therapies and show they are ineffective before the insurance company will agree to pay for the medication prescribed by their doctor.

    However, of greatest concern to health professionals and patient advocates are the number of pathways where health plans offer physicians pay-to-prescribe incentives linked to a narrow list of “on-pathway” therapies. For example, one large health plan pays doctors a $350 bonus payment per patient per month, as well as a $350 new patient fee, for selecting “on-pathway” treatments. Not only does this practice narrow patient choice but it erodes the doctor-patient relationship and the quality of medical care. Compounding the problem, the process by which insurers develop clinical pathways is not transparent – meaning patients may not know what treatments are covered on a pathway and whether their physician has a financial incentive to prescribe specific drugs.

    Addressing these problems will require adopting policies that require insurance companies to disclose information about their clinical pathways. For this reason, the cancer community is pressing for transparency standards so patients will have the right to know the specifics of the pathway that governs their care. Among the information patients need to know are what tests and treatments are covered under the pathway, if their physician’s payments are based on following the pathway, how the pathway covers the costs of being on a clinical trial, and if physicians have flexibility to prescribe “off-pathway” treatments that meet patients’ unique needs.

  • Tips for patients and caregivers to learn about treatment options

    Determining the best course of treatment is a daunting task for cancer patients and caregivers who rarely have the medical knowledge to evaluate the available options. Thus, patients place great trust in their care team in guiding them through the decision-making process and choosing a regimen that reflects that patient’s life circumstances and treatment goals.

    For this reason, having a frank discussion about the role of clinical pathways is more important than ever before. For patients and caregivers, this means starting the conversation about treatment options by asking the oncologist if the regimen will be determined by a clinical pathway. If the answer is yes, the next step is to get as much information as possible about the specific pathway, including:

    • What entity developed the pathway (a cancer center, physician practice, or a health plan)?
    • What treatment options are available through the pathway for the patient's diagnosis and why were they chosen?
    • Does the pathway include the option of enrolling in a clinical trial?
    • What happens if the oncologist prescribes a treatment not "on pathway"?
    • Does the insurance plan give financial incentives to the oncology practice for following the pathway?

    At the same time, the Affordable Care Act (ACA) now requires insurance companies to make available in concise, easy-to-understand language what their health plans cover. Although the main purpose is to make it easier for consumers to compare different plans, this information can also help cancer patients whose care is governed by a payer pathway.

    Ways to get information on the drugs covered through the health plan are to:

    • Visit the insurer’s website to review the list of prescriptions the plan includes.
    • Ask the insurance company to provide the Summary of Benefits and Coverage, 
a form that summarizes the key features of the plan, such as the covered benefits, cost-sharing provisions, and coverage limitations and exceptions.
    • Call the insurance company directly to find out what drugs are covered.

  • Are other scientifically valid treatment options available for my type and stage of cancer but not included in the pathway?
  • Why doesn’t the pathway include these other treatments?
  • Does the pathway allow me (my loved one) to enroll in a clinical trial?
  • Is there an avenue to go on a treatment regimen not covered through the clinical pathway?
  • What steps are required so I (my loved one) can take a cancer treatment that is “off pathway”?
  • Will there be a delay in getting the treatment if it is “off pathway”?
  • Will I have to pay more to take this treatment?
