PTA responsibilities, research, and ADA

Professional responsibilities in physical therapy

Ethics and jurisprudence

• Core principles:
  • Autonomy: Respect the patient’s right to make their own decisions.
  • Beneficence: Always act in the patient’s best interest
  • Nonmaleficence: “Do no harm” - avoid interventions that cause unnecessary injury or suffering
  • Justice: Deliver care fairly and without discrimination
  • Veracity: Be honest in all interactions with patients and colleagues

Informed consent and confidentiality

• Informed consent includes:
  • Explanation of diagnosis, proposed treatment, risks, and alternatives
  • Opportunity for questions
  • Voluntary agreement without coercion
• HIPAA compliance:
  • Secure storage of records
  • Only share information with authorized personnel
  • Obtain consent before discussing patient information with third parties

Legal considerations

• Negligence: Failure to provide standard care that results in harm
• Malpractice: Professional misconduct or lack of skill leading to injury
• Abandonment: Inappropriate discontinuation of care without proper notice or referral
  • Avoid by: Providing a transition plan, proper documentation, and clear communication
• Mandatory reporting: report suspected abuse, neglect, or fraud to the appropriate authority or supervisor, as required by state law and facility policy
• Workplace conduct: comply with OSHA safety standards and facility harassment policies; report violations through proper channels
• Cultural and socioeconomic awareness: consider a patient’s health literacy, cultural background, and socioeconomic situation when communicating and planning care

Supervision guidelines

• PTA supervision:
  • PTA must follow the PT’s plan of care
  • PT must be available for consultation
  • Supervision laws vary by state; direct or general supervision may be required
• PT aide supervision:
  • Aides may perform non-skilled tasks under direct supervision

Watch-out: A PTA carries out the PT’s established plan of care and collects data - the PTA does not perform the initial evaluation or re-evaluation, and does not set or change goals or the plan of care. If a patient’s status changes, the PTA recognizes it and communicates it to the supervising PT.

Delegation and communication

• Effective delegation:
  • Assign tasks based on the individual’s qualifications and legal scope
  • Ensure understanding of expectations
  • Monitor and provide feedback
• Professional communication:
  • Maintain professionalism in all written and verbal exchanges
  • Use SBAR (Situation, Background, Assessment, Recommendation) for concise clinical updates
  • If a patient shows an adverse response during a delegated intervention (e.g., abnormal vital-sign response, new chest pain, or dyspnea), stop the activity and report it to the supervising PT immediately

Research concepts and evidence-based practice

Levels of evidence

Understanding levels of evidence helps clinicians evaluate the strength of research when applying findings to practice:

• Level 1a: systematic review / meta-analysis of randomized controlled trials (RCTs)
• Level 1b: individual randomized controlled trials
• Level 2: cohort studies (prospective)
• Level 3: case-control studies (retrospective)
• Level 4: case series or low-quality cohort and case-control studies
• Level 5: expert opinion without critical appraisal

Study types and research designs

• Descriptive: Case reports, case series
• Analytical:
  • Observational: Cohort (prospective), case-control (retrospective), cross-sectional
  • Experimental: Randomized controlled trials (RCTs), the gold standard
• Qualitative: Thematic analysis, interviews, focus groups
• Quantitative: Uses numerical data to measure and test theories

Statistical concepts

P-values

• A p-value < 0.05 typically indicates a statistically significant difference
• A lower p-value suggests stronger evidence against the null hypothesis

Confidence intervals (CI)

• A 95% CI is a range that, across repeated sampling, would contain the true value about 95% of the time
• Narrow CI = more precise results; wide CI = more variability

Reliability and validity

• Reliability: Consistency of a test (test-retest, interrater, intrarater)
• Intrarater: The same clinician performs the test-retest
• Interrater: Different clinicians perform the test-retest
• Validity: Accuracy - does the tool measure what it’s intended to?
  • Construct validity, content validity, and criterion validity.

Sensitivity, specificity, predictive values

• Sensitivity: true positive rate; a highly sensitive test with a negative result rules out a condition (SnNOUT)
• Specificity: true negative rate; a highly specific test with a positive result rules in a condition (SpPIN)
• False negative: test result indicates a condition is absent when it is actually present
• False positive: test result indicates a condition is present when it is actually absent
• Positive predictive value (PPV): likelihood that a positive test result is correct
• Negative predictive value (NPV): likelihood that a negative test result is correct

Measurement scales

• Nominal: Categories without order (e.g., gender, blood type)
• Ordinal: Ordered categories (e.g., MMT grades, pain scale)
• Interval: Equal intervals, no true zero (e.g., temperature)
• Ratio: Equal intervals with a true zero (e.g., height, weight, time)

Hypothesis testing and data interpretation

• Null hypothesis (H₀): No difference or relationship
• Alternative hypothesis (H₁): A difference or relationship exists
• Type I error (α): False positive
• Type II error (β): False negative

Anchor for Type I vs Type II: picture a courtroom where the null hypothesis is “innocent.” A Type I error (α) convicts an innocent person - you reject a true null and claim a difference that isn’t really there (a false positive). A Type II error (β) lets a guilty person go free - you fail to reject a false null and miss a difference that really is there (a false negative).

HIPAA (Health insurance portability and accountability act)

Definitions

HIPAA

The health insurance portability and accountability act, passed by the U.S. Congress in 1996. It’s a federal law that establishes national standards protecting sensitive patient health information from being disclosed without a patient’s consent or knowledge.

HIPAA guidelines for PTA

• Access patient information only when directly involved in that patient’s care, following the “minimum necessary” standard for protected health information (PHI).
• Discuss patient information only with those involved in care, verify identity before sharing, and avoid discussing PHI in public areas such as elevators, hallways, or waiting rooms.
• Secure records: log off workstations when stepping away, never share login credentials, and retrieve or dispose of printed PHI promptly.
• Protect patient privacy during treatment with proper draping and positioning, and avoid discussing other patients during sessions.
• Send PHI only through approved, secure channels - never by personal text, email, or photo - and confirm the recipient before sending.

Healthcare system and practice management

Reimbursement models

• Medicare: Federal program for individuals 65 and older or with certain disabilities
• Medicaid: State-run program for low-income individuals
• HMO (Health Maintenance Organization): Requires PCP referral, lower cost
• PPO (Preferred Provider Organization): More flexibility, higher premiums

Documentation standards

• SOAP notes: Subjective, Objective, Assessment, Plan
• ICD-10: Diagnosis coding
• CPT codes: Billing for procedures
• Documentation must be timely, accurate, legible, and support skilled care

Continuum of care

• Acute care: Immediate medical care (hospital)
• Subacute care: Less intensive than acute, but still requires skilled therapy
• Outpatient rehab: For patients well enough to live at home
• Home Health: Therapy provided in the patient’s home

Discharge planning and case management

• Begins early in care
• Factors include:
  • Patient’s home environment
  • Support system
  • Functional status
  • Need for durable medical equipment (DME)
  • Recommendations for follow-up services

Roles of healthcare professionals

• PT/OT/ST: Provide specialized rehabilitative care
• Nurse: Monitor vital signs, administer medication
• Physician: Medical diagnosis and overall treatment plan
• Case manager: Coordinates discharge planning and resources
• Social worker: Helps with psychosocial support and community resources
