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
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
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
Research concepts and evidence-based practice
Levels of evidence
- Level 1a: Meta-analysis analyses systematic reviews of randomized controlled trials (RCTs)
- Level 1b: Individual randomized controlled trials
- Level 2a: Cohort studies (prospective)
- Level 2b: Case-control studies (retrospective)
- Level 3: Case series or low-quality cohort and case-control studies
- Level 4: 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: Random control trials (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 means there’s a 95% chance the true value lies within that range
- 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 positives — Rules out a condition (SnNOUT)
- False negative: Indicates the absence of a condition when it is actually present.
- Specificity: True negatives — Rules in a condition (SpPIN)
- Positive predictive value (PPV) — Likelihood that a positive test is correct
- Specificity: False positive – indicates the presence of a condition when it is actually absent.
- Negative predictive value (NPV) — Likelihood that a negative test 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
HIPAA (Health Insurance Portability and Accountability Act)
HIPAA guidelines for PTA
- Access Patient Information Only When Needed
- Access a patient’s medical record only when directly involved in that patient’s care.
- Do not view charts of family members, friends, coworkers, or patients not assigned to you.
- Follow the “minimum necessary” standard when reviewing protected health information (PHI).
- Protect Patient Privacy
- Discuss patient information only with individuals involved in the patient’s care.
- Avoid discussing patient information in public areas such as elevators, hallways, cafeterias, or waiting rooms.
- Verify patient identity before sharing information.
- Secure Electronic and Paper Records
- Log off computers when leaving a workstation.
- Never share passwords or login credentials.
- Retrieve printed PHI immediately and securely store or dispose of documents containing PHI.
- Maintain Confidentiality During Treatment
- Provide privacy during evaluations and treatment sessions whenever possible.
- Use draping and positioning techniques to protect patient dignity and privacy during care.
- Avoid discussing other patients during treatment sessions.
- Use Appropriate Communication Methods
- Send PHI only through approved and secure communication systems.
- Do not text, email, photograph, or record patient information using personal devices unless specifically authorized by organizational policy.
- Verify recipients before sending any patient-related information
Healthcare system and practice management
Reimbursement models
- Medicare: Federal program for individuals >65 or with 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
