CDI and ASL Interpreter Shortage: What Healthcare Organizations Need to Know
Accessible communication drives quality patient care. For Deaf and hard-of-hearing patients, this access relies on one vital resource: qualified medical interpreters, including American Sign Language (ASL) interpreters and Certified Deaf Interpreters (CDIs).
The problem? These professionals are in short supply and the gap between demand and availability is widening. For healthcare organizations, patients, and family members, that gap has real consequences: delayed care, compliance exposure, and potential misunderstanding of diagnosis and treatment plans.
Understanding the Difference Between ASL and CDI Interpreters
Before addressing the shortage, it's important to clarify who these professionals are and what roles they play—because not all interpreter needs are the same.
What Is an ASL Interpreter?
An ASL interpreter facilitates communication between hearing providers and Deaf patients using American Sign Language. These professionals are trained in both ASL and spoken English, enabling them to bridge conversations in real time across a wide range of clinical settings, including inpatient, outpatient, emergency, and telehealth encounters.
ASL interpreters form the backbone of Deaf patient communication in most routine healthcare encounters.
What Is a Certified Deaf Interpreter (CDI)?
A CDI is a nationally certified interpreter who is also Deaf. While hearing ASL interpreters are experts in bridging communication between spoken English and sign language, CDIs contribute something equally important: the lived experience of being Deaf. This unique perspective, combined with advanced interpreting skills, allows CDIs to connect with Deaf patients in ways that may not always be possible through traditional interpreting alone.
CDIs are particularly effective in complex, sensitive, or high stakes encounters where cultural understanding, visual communication strategies, and patient trust are critical to successful communication. CDIs undergo advanced interpreter training and typically work alongside a hearing ASL interpreter. They are called upon in situations where standard ASL interpretation alone may be insufficient.
CDI involvement is often most appropriate when a patient:
- Uses non-standard or regional sign language variants
- Has experienced language deprivation
- Has cognitive or developmental disabilities
- Is navigating a trauma or mental health crisis
- Has limited proficiency in traditional ASL
CDIs are particularly valuable in high-risk clinical situations where communication accuracy directly impacts patient safety, care quality, and legal compliance. These situations may include and are not limited to:
- Emergency department encounters, where rapid and accurate communication is essential
- Behavioral health evaluations, where nuanced communication affects diagnosis and safety
- Informed consent discussions, where patient understanding is a clinical and legal requirement
- End-of-life conversations, where communication quality has profound human consequences
- Complex diagnosis and treatment planning, where misunderstandings can lead to serious clinical harm
By bridging communication gaps that traditional interpreting alone may not address, CDIs help ensure patients fully understand and participate in their healthcare decisions.
Why the ASL Interpreter Shortage Continues
The shortage of qualified ASL and CDI interpreters is not a sudden development. It is the result of several converging pressures that have built over time.
A Limited Workforce
The pool of qualified healthcare ASL interpreters has always been small relative to demand. The CDI workforce is smaller still. Healthcare interpreting is a specialized discipline and requires not only fluency in ASL and English, but also a working knowledge of medical terminology, clinical workflows, and the ethical standards specific to healthcare settings.
These are not skills acquired quickly.
Rising Demand Across the System
At the same time, demand is increasing. Greater awareness of accessibility rights has expanded expectations among Deaf and hard-of-hearing patients. Regulatory requirements around language access and effective communication have grown more stringent. The rapid expansion of telehealth has introduced new settings where interpreter access must be maintained. And as healthcare organizations expand into specialized services, the need for interpreters with domain-specific knowledge increases in step.
Rigorous Certification and Continuing Education Requirements
Becoming a qualified healthcare ASL interpreter or CDI requires extensive education, certification, and ongoing professional development. The pipeline of newly certified professionals has not kept pace with the rate at which demand is climbing.
Geographic Barriers
In rural and underserved communities, proximity compounds the challenge. Local interpreter availability is often limited, and specialized CDI resources may simply not exist within a reasonable geographic radius. For organizations serving these populations, access becomes acute.
The Impact on Healthcare Organizations
When qualified ASL and CDI interpreters are unavailable, the effects ripple across operations, compliance, and patient experience.
Delays in Care
Scheduling qualified interpreters for appointments becomes a logistical challenge. Consultations are postponed. Specialty visits are delayed. In some cases, discharge timelines are extended because the appropriate communication support cannot be arranged in time. These delays affect patient throughput and care continuity in ways that compound over time.
According to the U.S. Department of Justice, PeaceHealth Southwest Medical Center agreed to pay $75,000 to a Deaf patient after failing to provide a qualified sign language interpreter during her hospitalization.
Compliance and Legal Risk
Healthcare organizations have clear obligations under the Americans with Disabilities Act (ADA) and Section 1557 of the Affordable Care Act to provide effective communication for Deaf and hard-of-hearing patients. The inability to secure appropriate interpreter services—or the practice of relying on family members or unqualified individuals as ad hoc interpreters—may not meet regulatory expectations and can expose organizations to significant legal and compliance risk.
This exposure led to legal consequences for one health system in 2024. The U.S. Department of Justice and HHS reached a $2 million settlement with the health system after finding that Deaf and Deaf-blind patients' rights were violated when they did not receive appropriate interpreter services.
Patient and Staff Experience
When interpreter services are difficult to secure, patients, their families, and healthcare teams are affected. Patients may leave encounters without fully understanding diagnoses, treatment options, or follow-up instructions, while staff face growing administrative burdens coordinating interpreter support. Over time, these communication barriers can impact satisfaction, trust, and care continuity.
Bridging Communication Gaps Standard Interpreting May Not Address
CDIs are uniquely equipped to bridge gaps that hearing ASL interpreters alone may not be able to close. When a patient uses idiosyncratic signing, has limited language exposure, or is in acute psychological distress, a CDI works within the interpreting team to ensure that meaning is conveyed accurately and completely. The result is better patient understanding, stronger engagement, and greater confidence that informed decisions are being made on solid communicative ground.
Strategies Healthcare Organizations Can Consider
The ASL interpreter shortage is a structural challenge—but it is one that healthcare organizations can prepare for and manage strategically. The following approaches can help organizations maintain access to qualified interpreters even as the workforce remains constrained.
Expand Access Through Video Remote Interpreting
Video remote interpreting (VRI) allows organizations to connect with qualified ASL and CDI interpreters remotely, overcoming geographic barriers that limit local availability. For organizations in underserved areas, or those facing acute scheduling challenges, VRI provides access to a broader network of specialized interpreters on demand.
AMN Healthcare Language Services platform provides HIPAA-compliant video interpretation for everyday devices, supporting providers, Deaf and hard-of-hearing patients and their families across a wide range of clinical settings. With integrations across 40+ EHR and telehealth platforms—including Epic—AMN Healthcare makes it possible to connect with a qualified interpreter directly from a clinical workflow, without additional hardware or manual coordination.
Partner With Specialized Language Service Providers
Not all language service providers maintain robust ASL and CDI networks. Organizations should prioritize partnerships with providers that have demonstrated capacity to fulfill both routine and urgent interpreter requests across these specialized categories.
AMN Healthcare is the top healthcare-exclusive language services provider in the United States, delivering interpretation across more than 300 languages with a 4.9/5 interpreter satisfaction rating from thousands of physician surveys. Their network is built specifically for healthcare, with the depth and compliance infrastructure to support complex, high-acuity interpreter needs.
As a leading employer for full-time and part-time CDIs (second to Gallaudet University), providers and patients can connect with an AMN Healthcare CDI or CDI/ASL interpreter team to work with their onsite interpreter. This versatility enhances access, trust, and continuity of care.
Develop Proactive Scheduling Processes
Reactive scheduling is a liability when interpreter availability is constrained. Healthcare organizations benefit from identifying recurring interpreter needs—such as regular appointments for known Deaf patients or routine scheduled procedures—and securing qualified resources in advance wherever possible. Building lead time into the scheduling process reduces the frequency of last-minute requests and the operational pressure that accompanies them.
Educate Clinical and Administrative Staff
Awareness is a prerequisite for appropriate action. Care teams should be aware that a particular session may warrant a CDI, in addition to an ASL interpreter. Targeted education for clinical staff—particularly those working in emergency, behavioral health, and complex care settings—can improve decision-making at the point of care and ensure that the right interpreter type is requested at the right time. Care teams should be aware that they can collaborate with their Deaf patient to determine the best accommodation. Deaf individuals are often the experts in determining the best fit for their medical appointments and care.
Looking Ahead: Building a More Resilient Language Access Program
The shortage of ASL and CDI interpreters is unlikely to ease in the near future, making proactive language access planning essential. Organizations that combine qualified interpreter networks, remote interpreting technology, and strong internal processes will be better positioned to meet compliance requirements and provide equitable care for Deaf and hard-of-hearing patients.
AMN Healthcare's Language Services help healthcare organizations improve access to qualified ASL and CDI interpreters through a nationwide network of healthcare-trained professionals and technology-enabled interpretation solutions.
