Information Acquisition — Gather client data from referrals, records, IEPs, and interviews under supervision - Nbcot Certified Occupational Therapy Assistant Cota

SECTION 1

Historical Context & Motivation

The process of information acquisition in occupational therapy has evolved substantially over the past century, shaped by broader movements in healthcare documentation, interprofessional collaboration, and evidence-based practice. Early occupational therapy practitioners in the 1910s and 1920s relied primarily on informal physician referrals and bedside observation, with minimal standardized data collection. As the profession matured, the need for systematic, reliable methods of gathering client information became increasingly apparent—particularly as reimbursement models, legal accountability, and collaborative care frameworks demanded thorough documentation. Today, the COTA operates within a structured supervisory relationship with the occupational therapist (OTR), gathering data from multiple sources including referrals, medical records, individualized education programs (IEPs), and client interviews to build a comprehensive picture of the client's occupational profile.

1917 • Founding of Occupational Therapy

The National Society for the Promotion of Occupational Therapy was established. Early practitioners gathered client information through informal physician notes and direct observation, with no standardized intake protocols.

1975 • IDEA and the Emergence of IEPs

The Education for All Handicapped Children Act (later IDEA) mandated Individualized Education Programs for students with disabilities, creating a formal document from which COTAs could gather educational and functional data for school-based OT services.

1996 • HIPAA and Standardized Records

The Health Insurance Portability and Accountability Act standardized how protected health information is stored, shared, and accessed, fundamentally shaping how COTAs obtain and handle client data from medical records and referral sources.

2008 • AOTA Occupational Profile Framework

The Occupational Therapy Practice Framework (OTPF-2) formalized the occupational profile as a core component of evaluation, emphasizing structured interviews and comprehensive data gathering as the starting point for all OT services.

2020 • Telehealth and Digital Data Collection

The COVID-19 pandemic accelerated adoption of telehealth and electronic health records, requiring COTAs to adapt information acquisition methods to virtual environments while maintaining supervisory oversight and data integrity.

Understanding this historical trajectory highlights a central question that drives Domain 1 competency: How does the COTA systematically collect, organize, and communicate client information from diverse sources—all while operating within the scope of practice and under the supervision of an OTR? Mastering this process ensures that intervention planning is grounded in accurate, holistic, and ethically obtained data.

SECTION 2

Core Principles of Information Acquisition

Effective information acquisition rests on several foundational principles that guide the COTA's data-gathering activities. These principles ensure that the information collected is comprehensive, accurate, ethically obtained, and useful for the supervising OTR's evaluation and intervention planning. The COTA must approach each data source with a clear understanding of what information it can yield, how to interpret that information within the client's occupational context, and what limitations or biases may affect the data's reliability.

Collaborative Supervision

All data gathering occurs under the direction and supervision of the OTR. The COTA contributes to—but does not independently conduct—the evaluation. Supervision may be direct (in-person) or indirect (phone, electronic), depending on state regulations and practice setting.

Multi-Source Triangulation

Reliable client profiles emerge from cross-referencing multiple data sources—referrals, medical records, educational documents, and interviews. No single source provides a complete picture; triangulation reduces error and reveals inconsistencies that warrant further exploration.

Client-Centered Focus

Information gathering prioritizes the client's occupational needs, goals, and life contexts. The COTA seeks to understand not just diagnoses and limitations, but also the client's strengths, routines, roles, cultural background, and personal priorities.

Ethical and Legal Compliance

Data acquisition adheres to HIPAA, FERPA (for educational records), informed consent requirements, and the AOTA Code of Ethics. The COTA must ensure proper authorization before accessing records or conducting interviews.

Systematic Documentation

All gathered information must be documented accurately, clearly, and in a timely manner. The COTA uses standardized formats and facility-specific protocols to ensure data is accessible to the treatment team and meets regulatory standards.

✦

KEY TAKEAWAY

Think of the COTA as an investigative journalist working under an editor (the OTR). Just as the journalist gathers testimony from witnesses, reviews public records, cross-references documents, and interviews key individuals before the editor writes the final story, the COTA collects and organizes data from referrals, records, IEPs, and client interviews so the OTR can synthesize a coherent evaluation and intervention plan. The journalist doesn't publish the story alone—but the story cannot be written without their groundwork.

SECTION 3

The Information Acquisition Process — Visual Overview

This flowchart illustrates the information acquisition process. The OTR directs the process at the top and bottom, while the COTA gathers data from four primary sources—referrals (blue), medical records (pink), IEPs/IFSPs (amber), and client interviews (emerald)—then documents and organizes findings for the OTR's evaluation.

The diagram above captures the essential hierarchy and flow of information acquisition in occupational therapy practice. Notice that the OTR bookends the process: the supervising therapist both initiates the data-gathering directive and synthesizes the collected information into a formal evaluation. The COTA's role, depicted in the middle tier, involves accessing each of the four primary data sources, extracting relevant occupational and health information, and organizing it in a format that is both clinically useful and compliant with documentation standards. This structure reflects the collaborative nature of the OTR–COTA relationship as defined by AOTA guidelines and state practice acts.

SECTION 4

Deep Dive — The Four Data Sources

Referrals

A referral is the formal request that initiates occupational therapy services and typically originates from a physician, nurse practitioner, or other authorized healthcare provider. In many practice settings, a physician's order is legally required before OT services can begin. The referral document provides critical baseline information: the client's primary diagnosis or presenting condition, the reason for the OT referral, any relevant precautions or contraindications (such as weight-bearing restrictions after orthopedic surgery or seizure protocols), and the anticipated frequency and duration of services. The COTA should review the referral carefully, noting discrepancies between the referral reason and the client's self-reported concerns, as these gaps often point to areas requiring further exploration during the interview process.

Medical Records

The medical record (also called the health record or chart) is a comprehensive repository of a client's health history, diagnoses, treatments, and outcomes. In contemporary practice, this is most often accessed through an electronic health record (EHR) system. Key data points the COTA should extract include the medical and surgical history, current medication list (with attention to side effects that may affect occupational performance, such as sedation, dizziness, or cognitive slowing), laboratory and imaging results relevant to functional status, progress notes from other disciplines (physical therapy, speech-language pathology, nursing, social work), and prior OT evaluations or discharge summaries. The COTA must be mindful of HIPAA regulations when accessing and discussing medical record information, ensuring that access is limited to what is necessary for treatment purposes.

Individualized Education Programs (IEPs) and IFSPs

In school-based practice, the Individualized Education Program (IEP) and the Individualized Family Service Plan (IFSP) are legally mandated documents under the Individuals with Disabilities Education Act (IDEA). The IEP, used for children ages 3–21, contains the student's present levels of academic achievement and functional performance, measurable annual goals, special education and related services (including OT), accommodations and modifications, and transition planning for students 16 and older. The IFSP, used for children from birth to age 3, focuses on the family unit and includes outcomes targeted for the child and family within natural environments. When gathering data from these documents, the COTA should identify existing goals that relate to occupational performance in the educational setting—such as fine motor skills for handwriting, sensory processing for classroom participation, or self-care skills for toileting and feeding—and note the student's progress toward those goals since the last review.

Client and Caregiver Interviews

The client interview is arguably the most client-centered data source, as it provides direct insight into the individual's lived experience, personal goals, cultural values, and perceived barriers to occupational engagement. Under the direction of the OTR, the COTA may conduct structured or semi-structured interviews using tools such as the Canadian Occupational Performance Measure (COPM) or the AOTA Occupational Profile template. The COTA should use open-ended questions to explore the client's occupational history ("Tell me about a typical day"), priorities ("What activities are most important to you right now?"), and environmental context ("Describe your home—are there stairs?"). When the client cannot self-report due to cognitive impairment, developmental stage, or medical status, the COTA may interview caregivers, family members, teachers, or other informants. Active listening, cultural humility, and therapeutic rapport are essential interviewing competencies.

⚠

Scope of Practice Reminder

The COTA gathers and reports data but does not independently interpret evaluation data or establish the occupational therapy diagnosis. Interpretation and clinical reasoning about the data's implications for intervention are the responsibility of the OTR. The COTA may share observations and preliminary impressions during supervisory meetings, contributing to the collaborative evaluation process.

Comparing Data Sources — What Each Reveals

This matrix uses circle size and opacity to indicate how much each data source contributes to different information domains. Note how client interviews are the primary source for client priorities, occupational history, and environmental context, while medical records excel at providing diagnostic and medication data. This visual reinforces why multi-source triangulation is essential—no single source covers all domains.

Data Source	Key Information Yielded	Common Pitfalls	Regulatory Framework
Referrals	Diagnosis, reason for referral, precautions, service frequency	Vague or incomplete referral information; outdated diagnosis codes	State practice acts, CMS conditions of participation
Medical Records	Medical/surgical history, medications, lab values, other disciplines' notes	Information overload; accessing data outside scope; outdated records	HIPAA Privacy and Security Rules
IEPs / IFSPs	Educational goals, accommodations, present levels, related services, transition plans	Goals not updated; educational jargon unfamiliar; incomplete related services documentation	IDEA (Parts B and C), FERPA
Client Interviews	Occupational history, personal goals, cultural context, environmental barriers, subjective experience	Leading questions; cultural insensitivity; failure to interview caregivers when needed	AOTA Code of Ethics, informed consent requirements

SECTION 6

Worked Example — Gathering Data for a New Client

Consider the following scenario: A COTA in an acute rehabilitation hospital receives direction from the supervising OTR to gather initial data on a new client, Mrs. Delgado, a 72-year-old woman admitted following a right cerebrovascular accident (CVA) with resulting left hemiparesis. The OTR asks the COTA to review available records, examine the referral, and prepare for an initial client interview. Walk through each step of the information acquisition process.

Case: Mrs. Delgado — Post-CVA Information Acquisition

1
Step 1 — Review the Referral

The COTA begins by reviewing the physician's referral order. The referral indicates: primary diagnosis of right CVA (ICD-10: I63.9), left hemiparesis, OT evaluation and treatment requested, frequency of 5×/week for 60-minute sessions, and precautions including aspiration risk (NPO, thickened liquids only) and fall risk. The COTA notes the aspiration precaution—this will influence any feeding or oral motor activities.

Key findings: Right CVA, left hemiparesis, aspiration and fall precautions documented.
2
Step 2 — Review Medical Records

Next, the COTA accesses the EHR and reviews the following: medical history (hypertension, type 2 diabetes, osteoarthritis bilateral knees), surgical history (right total knee replacement 2019), current medications (lisinopril, metformin, aspirin, atorvastatin—none with significant cognitive side effects), nursing notes indicating the client is alert and oriented ×3 but demonstrates left-sided neglect, and PT initial evaluation noting a Functional Independence Measure (FIM) score of 3 (moderate assist) for transfers. The COTA documents relevant findings and flags the left-sided neglect for discussion with the OTR, as this will significantly affect self-care and safety.

Key findings: Comorbidities affecting endurance and mobility; left neglect identified; FIM transfer score of 3.
3
Step 3 — Check for Educational/Community Records

Because Mrs. Delgado is an adult in an acute rehab setting, IEP and IFSP records do not apply. However, the COTA checks for any prior OT records in the system and finds a discharge summary from outpatient OT two years ago for right knee rehabilitation. This provides useful context regarding the client's baseline functional status and prior response to therapy (she was compliant and motivated, discharged having met all goals).

Key findings: No IEP applicable. Prior OT records reveal strong motivation and good therapy compliance.
4
Step 4 — Conduct the Client Interview

With OTR approval, the COTA conducts a semi-structured interview at bedside using open-ended questions. Mrs. Delgado reports that she lives alone in a single-story home, was independent in all ADLs prior to the stroke, drove herself to church and grocery shopping, and her primary goal is to return home and care for herself. Her daughter, present during the interview, adds that her mother was an avid gardener and cooked daily. The COTA uses therapeutic rapport skills—maintaining eye contact, reflecting emotions, and respecting pauses. Spanish is Mrs. Delgado's primary language; the COTA arranges for interpreter services for the next session to ensure full communication.

Key findings: Prior independence in ADLs/IADLs, lives alone (discharge planning concern), values cooking and gardening, Spanish-speaking (interpreter needed).
5
Step 5 — Document and Report to OTR

The COTA organizes all gathered information into a structured summary and presents it to the OTR during their scheduled supervisory meeting. The summary includes: referral details, pertinent medical history, medication list, precautions, nursing and PT observations, prior OT history, and interview findings including the client's goals, living situation, cultural and linguistic considerations, and prior level of function. The COTA refrains from making diagnostic or interpretive statements but highlights data points that may warrant the OTR's further clinical reasoning, such as the left neglect and the client's solo living arrangement.

Outcome: Comprehensive data summary provided to OTR, who will use it to complete the formal OT evaluation and develop the intervention plan.

SECTION 7

Strengths and Limitations of Each Data Source

Each data source brings unique advantages to the information acquisition process, but also carries inherent limitations that the COTA must recognize. Understanding these trade-offs helps the COTA and OTR determine which sources to prioritize and how much weight to give each piece of data when building the occupational profile.

Data Source	Strengths	Limitations
Referrals	Provides legal authorization for services; identifies primary diagnosis and precautions; establishes service parameters; available early in the process	Often lacks functional detail; may use outdated diagnostic codes; may not reflect the client's full clinical picture; referral reason may not align with client priorities
Medical Records	Rich, objective clinical data; longitudinal perspective on health trajectory; interdisciplinary input; provides medication and lab data critical for safety	Information overload; may contain errors or conflicting entries; HIPAA compliance demands vigilance; may not reflect current functional status if documentation is delayed
IEPs / IFSPs	Legally mandated; include measurable goals and progress data; reflect multidisciplinary team input; provide educational context essential for school-based OT	Goals may be outdated between annual reviews; educational jargon may differ from clinical terminology; may not address home or community performance; only applicable in pediatric/educational settings
Client Interviews	Most client-centered source; captures subjective experience and personal priorities; reveals cultural context, environmental factors, and occupational history; builds therapeutic rapport	Subject to recall bias and social desirability; requires intact cognition and communication; interviewer bias can shape responses; time-intensive; may require interpreter services

Strengths and limitations of the four primary data sources in OT information acquisition

✦

KEY TAKEAWAY

Consider each data source like a different lens on a camera. A referral is a wide-angle lens—it captures the broad scene but lacks fine detail. Medical records are a macro lens—they zoom in on biological specifics but miss the human context. An IEP is a polarizing filter—it works brilliantly in one lighting condition (educational settings) but is useless in another. The client interview is a portrait lens—it brings the person into sharp focus, showing their unique story, but it captures only their perspective. The skilled COTA cycles through all available lenses to compose the fullest possible picture for the OTR.

SECTION 8

Connecting Information Acquisition to Advanced OT Practice

Information acquisition is the foundational step in a broader chain of clinical reasoning that extends through the entire occupational therapy process. The data gathered by the COTA feeds directly into the OTR's evaluation, which includes interpretation of assessment results, identification of occupational performance problems, and formulation of the intervention plan. Understanding how information acquisition connects to these downstream processes helps the COTA gather data that is not merely comprehensive but strategically useful. For instance, knowing that the OTR will need to select standardized assessments helps the COTA prioritize data that clarifies which assessments are appropriate—screening for visual-perceptual deficits after a stroke, for example, signals that the OTR may administer the Motor-Free Visual Perception Test (MVPT).

Information Acquisition (COTA Role)	Evaluation & Intervention (OTR Role)
Reviews referral and identifies diagnosis, precautions	Selects appropriate standardized and non-standardized assessments based on referral data
Extracts medication lists and comorbidities from medical records	Considers pharmacological effects on occupational performance; adjusts intervention timing and intensity
Reviews IEP goals and present levels of performance	Develops educationally relevant OT goals that align with IEP team priorities and IDEA mandates
Conducts client/caregiver interview; documents goals, values, context	Integrates subjective client data with objective assessment results to create a client-centered intervention plan
Identifies environmental barriers (stairs, small bathroom, noisy classroom)	Plans environmental modifications, adaptive equipment, and contextual intervention strategies

How COTA data gathering supports OTR evaluation and intervention planning

As your OT career progresses, you will encounter increasingly complex cases requiring integration of data from electronic health records, interdisciplinary team conferences, standardized screening tools, and community-based informants. Advanced topics such as clinical reasoning frameworks (narrative, procedural, conditional, and pragmatic reasoning), evidence-based practice methodologies, and outcome measurement all build upon the competencies developed in information acquisition. The discipline and thoroughness you bring to data gathering as a COTA directly impacts the quality of every downstream decision in the therapy process.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

A COTA reviews a physician's referral for a new client and notices the referral lists "evaluate and treat" but provides no specific precautions or medical history. What is the most appropriate next step for the COTA, and why is relying solely on the referral insufficient for building a comprehensive occupational profile?

Show answer

The COTA should proceed to review the client's medical records in the electronic health record system and inform the supervising OTR about the limited referral information. Relying solely on the referral is insufficient because referrals typically provide only the diagnosis, reason for referral, and service parameters—they rarely contain detailed functional, medical, or psychosocial information. The COTA needs to triangulate data from multiple sources (medical records, prior therapy documentation, and client interview) to identify precautions, comorbidities, medications, and functional baseline information that are essential for safe and effective intervention planning.

Question 2: BASIC APPLICATION

A COTA working in a school setting is assigned to gather data on a 7-year-old student with autism spectrum disorder who is receiving OT services. The student's IEP is available for review. Identify three specific types of information the COTA should extract from the IEP to contribute to the OTR's re-evaluation.

Show answer

The COTA should extract: (1) the student's present levels of academic achievement and functional performance, including any data on fine motor skills, sensory processing, self-care, or social participation documented by the IEP team; (2) measurable annual goals related to OT, such as handwriting legibility targets, sensory regulation objectives, or self-care milestones, along with progress data indicating whether these goals have been met, partially met, or not met; and (3) the accommodations and modifications currently in place, such as use of a pencil grip, weighted vest, preferential seating, or extended time, which reveal what supports the student already requires and whether they have been effective.

Question 3: INTERMEDIATE

During a client interview, a COTA asks Mrs. Park, a 65-year-old woman with rheumatoid arthritis, about her daily routine. Mrs. Park states, "I do everything myself, I don't need help." However, the medical record notes from nursing indicate she requires moderate assistance for dressing and bathing. How should the COTA handle this discrepancy, and what does it illustrate about the limitations of interview data?

Show answer

The COTA should document Mrs. Park's self-report accurately without challenging or contradicting her in the moment, as doing so could damage therapeutic rapport. The COTA should then document the discrepancy between the interview data and the nursing notes and bring this to the OTR's attention during the supervisory meeting. This situation illustrates two key limitations of interview data: recall bias (the client may be recalling her pre-hospitalization function rather than her current status) and social desirability bias (the client may minimize her need for help due to cultural values, pride, or fear of losing independence). The OTR can then plan structured observations or standardized assessments to obtain objective functional data that clarifies the discrepancy.

Question 4: APPLIED

A COTA in a skilled nursing facility is directed by the OTR to gather preliminary data on Mr. Chen, an 80-year-old man admitted with a hip fracture following a fall. Mr. Chen has moderate dementia (documented MMSE score of 18/30) and speaks primarily Mandarin. His daughter is available by phone. Describe the COTA's complete information acquisition strategy, including which data sources to use, adaptations needed for the client's cognitive and linguistic barriers, and how to organize findings for the OTR.

Show answer

The COTA should employ all four data sources with specific adaptations. First, the referral should be reviewed for the hip fracture diagnosis, surgical details (e.g., open reduction internal fixation vs. total hip arthroplasty), weight-bearing precautions, and fall risk level. Second, the medical record should be examined for the dementia diagnosis and cognitive screening results, medication list (with attention to anticholinergics or sedatives that may worsen cognition), comorbidities, and prior functional status documented in any previous therapy or social work notes. Third, a caregiver interview with Mr. Chen's daughter should be conducted by phone using interpreter services, gathering information about his prior level of function, home environment (stairs, bathroom setup), daily routines, cultural practices (diet, family roles), and her concerns and goals for his rehabilitation. Fourth, a brief, adapted client interview with Mr. Chen should be attempted using simple, closed-ended questions (given his dementia), visual supports, and professional Mandarin interpreter services—not his daughter, to avoid role conflict. The COTA should organize findings into a structured summary categorized by source, highlight precautions and safety concerns, and present the document to the OTR with annotations about data reliability given the cognitive and linguistic challenges.

Question 5: CRITICAL THINKING

A COTA has gathered data from all four sources for a new pediatric client transitioning from early intervention (IFSP) to a school-based program (IEP). The IFSP goals focus on sensory processing and feeding in natural environments, while the incoming school district emphasizes academic readiness and classroom behavior. The parent expresses frustration that "the school doesn't care about the same things we worked on." Analyze how the COTA should present this data complexity to the OTR, and discuss the broader implications for client-centered practice when institutional frameworks generate conflicting priorities.

Show answer

The COTA should present the data to the OTR in a way that clearly delineates the information from each source while highlighting the tensions between them. This means documenting the IFSP goals and progress data alongside the school district's priorities, and including verbatim quotes from the parent interview that capture her concerns and values. The COTA should avoid making interpretive judgments but can organize the data to make the discrepancy visible—perhaps in a side-by-side format comparing IFSP goals with anticipated IEP areas of concern. This scenario illustrates a broader challenge in client-centered practice: when institutional mandates (IDEA Part C emphasizes natural environments and family-centered care; IDEA Part B emphasizes educational relevance) create discontinuities in how occupational needs are framed and addressed. The OTR, armed with the COTA's comprehensive data, can then facilitate a conversation with the IEP team and family about how sensory processing and feeding concerns translate into educational performance—for example, a child who cannot self-regulate sensory input may struggle with sustained attention in the classroom, and a child with feeding difficulties may be excluded from social participation at lunchtime. Client-centered practice demands that the parent's priorities are not dismissed but rather reframed within the new institutional context, finding alignment between family goals and educational outcomes.

SUMMARY

Lesson Summary

Summary

Information acquisition is the critical first step in the occupational therapy process, and the COTA plays an essential role by gathering client data from four primary sources under the supervision of the OTR. Referrals provide the legal authorization and initial clinical parameters for services, including diagnosis, precautions, and service frequency. Medical records offer rich, longitudinal clinical data including medical history, medications, laboratory values, and interdisciplinary progress notes—all governed by HIPAA regulations. IEPs and IFSPs, mandated under IDEA, are indispensable in pediatric and school-based settings for understanding educational goals, accommodations, and functional performance within the academic context.

Client and caregiver interviews are the most client-centered data source, revealing occupational history, personal priorities, cultural context, and environmental barriers that no document can fully capture. The guiding principle of multi-source triangulation ensures that the occupational profile is comprehensive and that discrepancies across sources are identified for further exploration. Throughout this process, the COTA must maintain ethical and legal compliance, document findings systematically, and communicate all gathered data to the OTR—who holds the responsibility for interpreting evaluation data and establishing the intervention plan. Mastering information acquisition positions the COTA as an indispensable partner in delivering high-quality, evidence-based occupational therapy services.
