When Prior Auth Delays Treatment: The Patient Impact Data
Prior authorization was designed as a cost containment tool — a way for payers to ensure that requested treatments are medically necessary before committing to coverage. Whatever its intended purpose, the practical effect of prior authorization on patient outcomes has become increasingly difficult to ignore. A growing body of research and physician survey data reveals that treatment delays caused by prior authorization are not just administrative inconveniences. They produce measurable harm.
The Scope of the Problem
The AMA's 2023 Prior Authorization Physician Survey provides some of the most widely cited data on patient impact. Among the findings: 94% of physicians reported that prior authorization delays access to necessary care. Eighty percent reported that prior authorization can lead to treatment abandonment. And 35% reported that prior authorization has led to a serious adverse event — including hospitalization, a life-threatening event, disability, or death — for a patient in their care.
These numbers are not marginal. When more than a third of physicians report that an administrative process has contributed to a serious adverse event for their patients, the process merits rigorous examination. The question is no longer whether prior authorization affects patient outcomes — the evidence is clear that it does. The question is how significant the impact is and what can be done about it.
Treatment Abandonment
One of the most well-documented consequences of prior authorization delays is treatment abandonment. When patients face barriers to receiving prescribed treatment — whether those barriers are outright denials, extended delays, or the administrative burden of navigating the authorization process — a significant percentage simply give up.
Studies published in the American Journal of Managed Care and other peer-reviewed journals have found treatment abandonment rates ranging from 10% to over 40% depending on the therapy, the disease state, and the payer. Specialty medications tend to have the highest abandonment rates, which is particularly concerning because these medications are typically prescribed for serious chronic conditions where treatment discontinuity has significant clinical consequences.
Treatment abandonment is not always a conscious decision by the patient. In many cases, patients do not understand why their treatment is being delayed, do not know that an authorization process is underway, or assume that the delay means the treatment is not available to them. The communication gap between the payer's decision-making process and the patient's understanding of their own care creates situations where patients fall through the cracks — not because they chose to forgo treatment, but because the system failed to keep them connected to their care plan.
Disease Progression During Delays
Many conditions do not wait for insurance companies to make decisions. Rheumatoid arthritis causes progressive joint damage. Cancer cells continue to divide. Inflammatory bowel disease erodes the intestinal lining. When treatment is delayed by days, weeks, or months due to prior authorization, the disease continues to advance — and in many cases, the damage that occurs during the delay is irreversible.
Research in rheumatology has demonstrated that early initiation of biologic therapy is associated with better long-term outcomes, including less radiographic joint damage and higher rates of clinical remission. Every week of delay in starting appropriate therapy is a week of continued disease activity. The concept of a "window of opportunity" for treatment — a period early in the disease course when aggressive treatment yields the greatest benefit — is well-established in rheumatology, oncology, and other specialties. Prior authorization delays narrow that window.
A study published in Arthritis Care & Research found that patients with rheumatoid arthritis who experienced prior authorization delays of more than one month had significantly worse disease activity scores at six months compared to patients who began treatment promptly. The clinical implications are clear: delays have consequences that extend well beyond the authorization period itself.
Emergency Department Utilization
When patients cannot access the treatments their physicians have prescribed, they are more likely to experience acute exacerbations that require emergency care. This is one of the most paradoxical aspects of prior authorization as a cost containment tool — the savings generated by denying or delaying a $500 medication may be offset many times over by a $15,000 emergency department visit and hospital admission.
Data from the Healthcare Cost and Utilization Project (HCUP) and other sources consistently shows that patients with poorly controlled chronic conditions — the same patients most likely to need specialty medications that require prior authorization — are the highest utilizers of emergency services. While the causal chain is complex and multiple factors contribute to emergency utilization, the association between treatment access barriers and downstream acute care costs is well-established in the health economics literature.
Mental Health and Patient Well-Being
The impact of prior authorization delays extends beyond the physical disease. Patients who are told that their physician has prescribed a treatment but that the treatment must first be approved by their insurance company experience anxiety, frustration, and a sense of powerlessness. For patients already coping with serious illness, this additional stressor is clinically significant.
Qualitative research on the patient experience of prior authorization has documented themes of confusion, anger, and distrust. Patients describe feeling caught between their doctor and their insurance company, unsure of who is making decisions about their care, and fearful that their treatment will be denied. These psychological effects are difficult to quantify, but they are real and they affect patients' overall well-being, their trust in the healthcare system, and their willingness to engage with care.
The Physician Perspective
Physicians consistently identify prior authorization as one of the most significant barriers to practicing medicine according to their clinical judgment. The AMA survey found that 79% of physicians described the prior authorization burden as "high" or "extremely high." Beyond the time and administrative cost, physicians report a moral dimension to the problem: they prescribe treatments that they believe are in their patients' best interest, and then an external entity overrides or delays that clinical judgment through an administrative process.
This experience contributes to physician burnout — a well-documented crisis in American medicine that the prior authorization burden compounds. When physicians spend hours each week on prior authorization paperwork instead of seeing patients, when they watch patients deteriorate while waiting for authorization, and when they feel that their clinical expertise is being second-guessed by payer algorithms, the cumulative effect on professional satisfaction and well-being is substantial.
What the Data Demands
The evidence on prior authorization's impact on patient outcomes points in a clear direction: the current system produces harm that must be weighed against whatever cost savings it generates. This does not mean that all utilization management is inappropriate — but it does mean that the way prior authorization is currently implemented, with its delays, inconsistencies, and opacity, is causing measurable damage to patient health.
For practices, the imperative is twofold. First, minimize the impact on your patients by processing authorizations as quickly and effectively as possible — comprehensive documentation, timely submission, aggressive follow-up, and immediate appeals when denials occur. Second, track and document the patient impact within your own practice. When you can quantify how many patients experienced treatment delays, how many abandoned treatment, and what the clinical consequences were, you have the data needed to advocate for change — whether with individual payers, at the state legislative level, or through professional organizations.
The patients who bear the burden of prior authorization delays did not choose this system. They are relying on their physicians and their practices to navigate it on their behalf. Every day that a practice improves its prior authorization processes is a day that patients get closer to the timely care they need and deserve.
