The Audiology Clinical Practice Algorithms and Statements developed by the Joint Audiology Committee on Clinical Practice (the American Speech-Language-Hearing Association, the Department of Veterans Affairs, and the American Academy of Audiology), approved by the ASHA Audiology/Hearing Science Assembly (LC A/HS 2-99), is an official statement of the American Speech-Language-Hearing Association. Joint committee member organizations and their respective representatives who prepared this document include, from ASHA: Evelyn Cherow and Lawrence Higdon; from the Department of Veteran Affairs: Gene Bratt, George Haskell, and Douglas Noffsinger; and from the American Academy of Audiology: Patricia McCarthy (chair), Kathleen Campbell, and Alison Grimes. Consultants and ex officios to the joint committee included Lucille Beck, Deborah Hayes, Gay Ratcliff, Kyle Dennis, and Charles Martinez.
Communication disorders are among the commonest of disabling conditions in the population of the United States. Problems affecting hearing, speech, and/or language are estimated to affect 10–15% of the populace, and the number of people with such problems increases as the population ages. To take but one example, 20–26 million U.S. citizens have hearing loss.
In 1996 and 1997, three major national organizations whose membership is composed of or includes audiologists and speech pathologists, professionals who deal with hearing, speech, and language problems, began exploring ways to make clinical services and clinical decision making provided by their members more effective. This was done in the context of the efforts by the Agency for Health Care Policy and Research, U.S. Department of Health and Human Services, to enhance the quality, appropriateness, and effectiveness of health care services and access to such services.
The three organizations—the American Speech-Language-Hearing Association (ASHA), the American Academy of Audiology (AAA), and the Department of Veterans Affairs (VA)—are officially incorporated or defined agencies whose memberships encompass virtually all board-certified public- and private-sector audiologists and speech-language pathologists in the United States. In addition, the VA is the largest single employer of such professionals in the nation. Although each of these organizations and many smaller and/or affiliated groups has made attempts in the past to look at quality, effectiveness, and appropriateness of the clinical services provided by their members, no coordinated effort by the three had occurred, either in development of clinical guidelines and standards, or in discussing related issues and differences.
After preliminary planning, a first meeting involving top administration from each group was held in Fort Lauderdale in 1997. Out of that meeting grew a plan to identify and develop clinical practice statements that met the 1990 Institute of Medicine definition that …” Clinical practice guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances.” The proposed joint enterprise sought to achieve professional consensus. It recognized longstanding efforts to define clinical practice patterns and guidelines by ASHA, additional relevant positions and products of AAA, and the goal of the VA to establish clinical guidelines including step-by-step decision trees called clinical algorithms.
After agreeing on the need for such an effort, a Joint Audiology Committee on Clinical Practice was established. It had members that included and/or were chosen by the top administration of the three organizations. Four face-to-face meetings and several telephone conferences were held in 1997–1999. The focus of all of the meetings was to achieve consensus and to identify areas in which common policy for the entire profession would benefit recipients of care, to develop practice documents that reflected common ground among the participants, and to make decisions that incorporated the best of research, clinical study, and national peer review in the areas of choice.
The members of the Joint Audiology Committee on Clinical Practice Algorithms and Statements (and their responsibilities when appointed) included:
Gene Bratt, PhD, Chief, Audiology and Speech Pathology, Nashville VA Medical Center; Past Chair, VA National Field Advisory Council in Audiology and Speech Pathology.
Kathleen Campbell, PhD, Associate Professor of Audiology, Southern Illinois University; Chair, National Task Force on Professional Practice Standards, American Academy of Audiology.
Evelyn Cherow, MA, Director, Audiology Division, American Speech-Language-Hearing Association.
Alison Grimes, MA, Director, Providence Speech and Hearing Center (CA); Member, Board of Directors, American Academy of Audiology.
George Haskell, PhD, Chief, Audiology and Speech Pathology, Iowa City VA Medical Center; Member, VA National Field Advisory Council in Audiology and Speech Pathology.
Lawrence Higdon, MA, Director, Audiolabs (TX); Vice President for Professional Practices in Audiology, American Speech-Language-Hearing Association.
Patricia McCarthy, PhD, Joint Audiology Committee Coordinator; Director of Audiology, Rush-Presbyterian-St. Luke's Medical Center, Chicago; Member, Board of Directors, American Academy of Audiology.
Douglas Noffsinger, PhD, Professional Department Chair, Audiology and Speech Pathology, VA Greater Los Angeles Healthcare System; Chair, VA National Field Advisory Council in Audiology and Speech Pathology.
Several professionals served in ex officio or consultant capacities to the committee during its deliberations, including: Lucille Beck, PhD, National Director, VA Program in Audiology and Speech Pathology; Deborah Hayes, PhD, President, American Academy of Audiology; Gay Ratcliffe, PhD, Vice President for Administration and Planning, American Speech-Language-Hearing Association; Kyle Dennis, PhD, Chief, Audiology and Speech Pathology, VA Greater Chicago Healthcare System; and Charles Martinez, MA, Associate Chief, Audiology and Speech Pathology, VA West Los Angeles Healthcare Center.
The overall goal of the audiology projects was to maximize the value of health care delivered to patients and clients. National consensus was sought on ideal practices, on maximizing quality through achieving desired outcomes, on customer satisfaction, and on efficient and appropriate use of procedures and resources. The target measures—audiologic assessment, hearing aid selection and fitting, and cochlear implant procedures—were procedures that were done frequently, were expensive, and/or carried some risk. The effort assumed that clinical practice statements and algorithms are useful to the degree that:
they reflect the best of basic and clinical research and experience;
they offer both guidance and opportunities for education in clinical decision making; and
they reduce variation in care where appropriate, thereby optimizing resource utilization.
A Joint Audiology Committee, consisting of representatives of the American Academy of Audiology (AAA), the American Speech-Language-Hearing Association (ASHA) and the Department of Veterans Affairs (VA), was formed to develop a set of Practice Statements and accompanying Algorithms for the profession of Audiology in order to provide a concise framework for the provision of quality audiologic services. These practice statements and accompanying algorithms are not intended to replace policy documents of the respective organizations that comprise the Joint Committee on Audiology. These Statements and Algorithms represent the collaboration and cooperation of the three named audiology constituencies.
The purpose of clinical practice statements and their associated decision trees (algorithms) is to recommend doing or not doing procedures to solve a clinical problem. Audiologists use them to outline the types of procedures they may conduct and interpret based on a patient's presenting concern and history. Although they are not intended to prescribe a particular protocol, they are representative of current preferred audiology practice and can serve as useful reference for other professionals, accrediting bodies, administrators, and third-party payors.
In these documents, Practice Algorithms provide diagrammed guidelines using a step-by-step decision tree. Practice Statements accompanying each algorithm serve as support documents that provide further explanation of the clinical process. To date, five Audiologic Practice Statements and Algorithms have been developed: Overview of Audiologic Services; Comprehensive Audiologic Assessment (adult); Comprehensive Audiologic Assessment (pediatric); Hearing Aid Selection and Fitting; and Cochlear Implant Assessment, Programming, and Audiologic Rehabilitation (adult). Although pediatric audiologic assessment is not currently a major concern of the VA, it may become so.
The Overview of Audiologic Services Algorithm provides a visual representation of audiology services delivery as a whole. The other four algorithms and statements present the implementation of this overview. Each statement and algorithm reflects practice that is based on current research and clinical literature. Further, each algorithm and statement is supported by a bibilography that includes position statements, guidelines, tutorials, related documents, and reports developed by the Department of Veterans Affairs, ASHA, as well as AAA. How these are used and coded is explained shortly.
Several professional constants common to all Practice Statements and Algorithms follow. (See Core Documents A, B, D–G in Table 1.)
Personnel: Audiologists are autonomous professionals who diagnose and treat individuals with auditory, balance and related disorders. Audiologists have masters and/or doctoral degrees in audiology from regionally accredited universities. Most states have audiology licensure, certification, or registration. National professional organizations have Codes of Ethics and specific credentials: the American Speech-Language-Hearing Association requires the Certificate of Clinical Competence-Audiology (CCC-A) and the American Academy of Audiology recommends Board Certification in Audiology, American Board of Audiology.
Referrals: Audiologists receive referral for services from a variety of sources, e.g., educators, health care professionals, government and private agencies, consumer organizations, as well as self-referral. Audiologists refer out to other professionals. Referral also may be made using Common Procedural Terminology (CPT) codes and/or affiliated nomenclature.
Population: Audiologists serve individuals of all ages.
Equipment and Test Environment: Testing is conducted as appropriate in an environment where ambient noise levels meet current American National Standards Institute (ANSI) standards. Electroacoustic equipment meets manufacturers' and the current ANSI standards for such equipment.
Safety and Health Precautions: All procedures ensure the safety of the patient and audiologist as well as adhere to Standard Health Precautions (e.g., prevention of bodily injury and transmission of infectious disease).
(Literature references to common elements of the algorithms/statements are included in each set of documents. The Joint Committee Overview of Audiology is Algorithm 1.)
The Joint Audiology Committee created a plan to develop the clinical practice statements and algorithms. The plan included national peer review and clinical-expert and administrative review at appropriate points. The plan was premised on the need for documents that represented a true consensus of the profession. A schematic of that process is graphed in Figure 1.
In summary, the algorithms and supporting practice documents have now been reviewed by top administration and peer reviewed by clinical leaders and practitioners of all three constituent organizations nationally. This includes review by the eleven members of the ASHA Executive Board, the twelve members of the AAA Board of Directors, and the nine members of the VA National Field Advisory Council in Audiology and Speech Pathology. In addition, reviews were sought from the 150 members (practicing professionals) of the ASHA Legislative Council and from 78 audiologists and related professionals chosen by the Joint Committee nationally as part of a peer-review process. These reviews sought opinion from allied health professionals and practicing audiologists/speech pathologists in every state in the country. In addition, the activities and draft documents of the Joint Audiology Committee were presented in open session at the national meeting of the American Academy of Audiology in Los Angeles in 1998, and transcripts of that session were kept.
The reviews from all sources were considered on an item-by-item basis by the Joint Audiology Committee, and the documents contained in this submission include those modifications. The final stage in this long-term effort sought final approval of the practice algorithms and statements from the organizations, namely, from the ASHA Audiology Assembly, from representatives of the Undersecretary for Health for the VA (through the Director of Audiology and Speech Pathology and her Field Advisory Council, the VHA Advisory Council for Adoption, Development and Implementation of Clinical Guidelines, and the VHA Offices of Patient Care Services and Policy, Planning, and Performance), and from the Board of Directors including the President of AAA.
Each of the remaining four algorithms is accompanied by a practice statement. The practice statement includes definitions of certain critical variables that apply to each algorithmic decision tree. Some categories requiring definition are common to all procedures. These include: (1) Personnel; (2) Referrals; (3) Associated Common Procedural Codes (CPT); (4) Population; (5) Clinical Indicators; (6) Objectives; (7) Expected Outcomes; (8) Clinical Process; (9) Equipment and Test Environment; (10) Safety and Health Precautions; and (11) References.
The eleven common factors defined for each audiologic procedure are those that the literature, previous guidelines in many fields, and clinical experience suggest are essential in efficient, comprehensive, clinical decision making. The definitions may differ from procedure to procedure, but each factor must be defined for proper and consistent use of the procedure.
Core Materials. Certain documents (including previous guidelines to preferred practice patterns, national consensus guidelines, ethical considerations, standards and scopes of practice, and health and safety considerations) were regarded as Core Materials and were consulted in preparation of each practice statement and algorithm. Those are tabled here and given an alphabetic code (A), (B) etc. The codes are used to reference the documents and these references appear throughout the entire set of algorithms.
Algorithm-Specific Materials. In addition to the Core Materials, selected key references are included in a bibliography that ends each clinical practice statement. These literature items were considered by the Joint Committee to contain generic work whose value has been tested by clinical trial, laboratory research, or analysis of outcomes data, or to be consensus guidelines or nationally developed regulations and procedures. For each practice statement and associated algorithm, these items are given a numeric code—(1), (2) etc. The codes are used to reference the items. The codes refer only to the references in the clinical practice statement associated with the particular algorithm in question.
Comments. At certain steps in the algorithms, the JAC thought certain comments were sufficiently important to insert them in the algorithm. These comments are labeled (e.g.): Attention: Comment [1]. The step in the algorithm to which the comment is related is similarly labeled (e.g.): [1].
Strength of Evidence and Recommendation. Although each audiology algorithm is supported by a clinical practice document with a reference list of work that contributed to the steps in the algorithm, and by core documents that contain consensus statements, research and clinical-trial-based preferred practices in audiology in 1999, the Joint Committee also made decisions about the supporting evidence and strength of its recommendation based on all of the materials and existing guidelines reviewed.
The strength of evidence assessment used a modified form of the process recommended by the Agency for Health Care Policy and Research and by the Veterans Health Administration's Advisory Council for Adoption, Development, and Implementation of Clinical Guidelines.
5. Using the Audiology Practice Statements and Algorithms. To illustrate, if an “action box” in an algorithm contains instructions such as “Perform Selection Measures” and the notation “(A)(1–3)(I)”, this code instructs the user that document A in the Core Materials and references 1–3 in the practice statement associated with this particular algorithm contain evidence and/or information of value about the instructions/action. It also informs the user that the Joint Committee's review of the Core Materials tabled earlier, and the references cited in the associated practice statement for this algorithm, resulted in a “strength of evidence and recommendation” of (I), i.e., the evidence was strong and the recommendation is accepted, useful, and effective.
The algorithms and statements follow, and are organized in this fashion:
Algorithm 1. Joint Audiology Committee Algorithm on Overview of Audiologic Services. (See Statement 1, JAC overview, in previous text at [2. C.]).
Algorithm 2. Joint Audiology Committee Algorithm on Comprehensive Audiologic Assessment (developmental age 5 years through adult). JAC Statement 2 on Comprehensive Audiologic Assessment (developmental age 5 years through adult) follows the algorithm.
Algorithm 3. Joint Audiology Committee Algorithm on Hearing Aid Selection and Fitting (adult). JAC Statement 3 on Hearing Aid Selection and Fitting (adult) follows the algorithm.
Algorithm 4. Joint Audiology Committee Algorithm on Cochlear Implant Assessment, Programming, and Audiologic Rehabilitation (adult). JAC Statement 4 on Cochlear Implant Assessment, Programming, and Audiologic Rehabilitation (adult) follows the algorithm.
Algorithm 5. Joint Audiology Committee Algorithm on Pediatric Comprehensive Audiologic Assessment (developmental age neonate to 5 years). JAC Statement 5 on Pediatric Comprehensive Audiologic Assessment (developmental age neonate to 5 years) follows the algorithm.
This statement and accompanying algorithm describe the audiologic care provided to patients who receive audiologic assessment. The components of patient care described are not intended to be all-inclusive. Professional judgment and individual patient characteristics may substantially affect the nature, extent, and sequence of services provided. All services are provided in compliance with State and Federal legislation and regulations.
Personnel: Audiologists are autonomous professionals who diagnose and treat individuals with auditory, balance, and related disorders. Audiologists have masters and/or doctoral degrees in audiology from regionally accredited universities. Most states have audiology licensure, certification, or registration. National professional organizations have Codes of Ethics and specific credentials: the American Speech-Language-Hearing Association requires the Certificate of Clinical Competence-Audiology (CCC-A) and the American Academy of Audiology recommends Board Certification in Audiology, American Board of Audiology.
Referrals: Audiologists receive referral for services from a variety of sources, such as educators, health care professionals, government and private agencies, consumer organizations, as well as self-referral. The typical terminology used in referrals for audiologic assessments includes “hearing test/examination/exam,” “audiogram and/or tympanogram,” “hearing evaluation,” and “comprehensive audiometry threshold evaluation.” Referral also may be made using common procedural terminology (CPT) codes and/or affiliated nomenclature.

This statement and accompanying algorithm describe the audiologic care provided to pediatric patients who receive audiologic assessment. The components of patient care described are not intended to be all-inclusive. Professional judgment and individual patient characteristics may substantially affect the nature, extent, and sequence of services provided. All services are provided in compliance with state and federal legislation and regulations.
Personnel: Audiologists are autonomous professionals who diagnose and treat individuals with auditory, balance, and related disorders. Audiologists have masters and/or doctoral degrees in audiology from regionally accredited universities. Most states have audiology licensure, certification, or registration. National professional organizations have Codes of Ethics and specific credentials: the American Speech-Language-Hearing Association requires the Certificate of Clinical Competence-Audiology (CCC-A) and the American Academy of Audiology recommends Board Certification in Audiology, American Board of Audiology.
Referrals: Audiologists receive referral for services from a variety of sources, e.g., educators, health care professionals, government and private agencies, consumer organizations, as well as self-referral. The typical terminology used in referrals for pediatric audiologic assessments includes “hearing test/examination/exam,” “audiogram and/or tympanogram,” “hearing evaluation,” and “comprehensive audiometry threshold evaluation.” Referral also may be made using common procedural terminology (CPT) codes and/or affiliated nomenclature. Audiologists refer out to other professionals.

Audiologic Clinical Process: The pediatric assessment components described are not designed to be all inclusive. The clinical decision making process is based on professional judgment and individual patient characteristics. The assessment process may vary from this guideline based on patient needs, cooperation, and the assessment setting. Decision making and interpretation regarding audiologic diagnostic and rehabilitative implications of information, observations, and results occur throughout this process.
For neonates and infants at birth through 6 months development age, the components of the audiologic assessment may include:
History
Appropriate physical examination (e.g., otoscopy)
Cerumen management
Otoacoustic emissions
Electrophysiologic assessment (ABR for the purpose of auditory threshold estimation or for the purpose of assessing neuro-otologic status)
Audiologic rehabilitation status
Any behavioral observation assessment is intended for corroboration of parent/caregiver report of the child's auditory behavior rather than for threshold estimation.
The components of the assessment for children at six months developmental age and above may include:
History
Appropriate physical examination (e.g., otoscopy)
Cerumen management
Use of developmentally appropriate procedures to obtain air- and bone-conduction, pure tone, and speech thresholds with appropriate masking for each ear
When it is not possible to obtain the above measures for each ear separately, testing should be completed in a calibrated sound field using frequency-specific stimuli (e.g., warbled pure tones) and speech stimuli. Developmentally appropriate techniques may include: Visual Reinforcement Audiometry (VRA), Conditioned Play Audiometry, Tangible Reinforcement Operant Conditioning Audiometry (TROCA), Visual Reinforcement Operant Conditioning Audiometry (VROCA), Behavioral Observation Audiometry (BOA), etc.
Acoustic immittance measures including tympanometry and acoustic reflex measures
Audiologic (re)habilitative and educational needs assessment
Otoacoustic emissions (OAE)
Electrophysiologic Assessment (e.g., ABR) for the purpose of auditory threshold estimation or for the purpose of the neuro-otologic status
Determination of the need to rule out VIIIth nerve or central disorder
CNS/CAP disorder and/or balance disorder
Speech-language screening
Components of management include but are not limited to:
Interpretation and documentation of assessment process results
Development of recommendations for further audiologic follow-ups, including amplification, cochlear implants, or assistive devices
Development of recommendations for audiologic follow-up and referral for and coordination with other services; and for education, guidance, and counseling as appropriate
Provision of counseling and education to patient, family, and/or caregivers
Equipment and Test Environment: Testing is conducted as appropriate in an environment where ambient noise levels meet current American National Standards Institute (ANSI) standards. Electroacoustic equipment meets manufacturers' and the current ANSI standards for such equipment.
Safety and Health Precautions: All procedures ensure the safety of the patient and audiologist and adhere to Standard Health Precautions (e.g., prevention of bodily injury and transmission of infectious disease.)
