The Role of Patient Reported Outcomes in Clinical Care

Summary: "The Role of Patient Reported Outcomes in Clinical Care"

Speaker: Assistant Professor, Division of Gastroenterology & Hepatology, Indiana University

Clinical Focus: End-stage liver disease, transplant, healthcare utilization, patient-reported outcomes (PROs)

1. Main Clinical Topics Discussed

• Definition, classification, and theoretical framework of Patient-Reported Outcomes (PROs)
• Application of PROs in clinical care, clinical research, and population health
• Gaps in outpatient chronic disease management, with emphasis on cirrhosis/end-stage liver disease
• Emerging digital health tools and value-based/patient-centered care models

2. Key Learning Points, Guidelines, and Recommendations

Defining PROs:

• PROs are outcome data reported directly by patients, without clinician or proxy interpretation
• Measured using validated instruments called Patient-Reported Outcome Measures (PROMs)
• Key domains include: physical, mental, and social quality of life (QoL); symptom burden; health behaviors; functional status; health-related social needs; patient safety perceptions; and treatment adherence/activation

Taxonomy of Outcome Types:

• Observer-reported outcomes (e.g., nurse documentation)
• Performance-based outcomes (e.g., pulmonary function tests, exercise stress testing)
• Disease surrogates (e.g., MELD score in liver disease)
• Survival/mortality endpoints
• Clinician-reported outcomes
• PROs — distinct in capturing the patient's own perspective

Regulatory and Research Standards:

• The FDA and European Medicines Agency (EMA) recommend PROs be designated as primary endpoints when a drug's labeling claim relates to patient experience (e.g., pain relief)
• PROs must be collected directly from patients using validated tools to minimize bias
• PROs used for adverse event (AE) monitoring have demonstrated less collection bias compared to clinician-interpreted AE reporting
• This has driven development of patient-reported Common Terminology Criteria for Adverse Events (PRO-CTCAE)

Clinical Use Levels:

• Micro level: Individual patient–clinician interaction and shared decision-making
• Meso level: Variation monitoring across providers, departments, or health systems (e.g., UK orthopedic surgery PRO benchmarking for knee replacement outcomes)
• Macro level: Population health monitoring and health policy guidance

3. Specific Clinical Data, Statistics, and Study Results Cited

• NIH PROMIS Initiative (Patient-Reported Outcomes Measurement Information System): A large, decade-long federally funded project that developed infrastructure and validated instruments for PRO measurement across disease states
• PCORI (Patient-Centered Outcomes Research Institute): Established in 2010; funds patient-centered research in which PROs frequently serve as primary outcomes
• CDC "Healthy People" Initiative: Longitudinal national program that has progressively incorporated QoL, social behavior, and life-stage development metrics into the definition of health — reflecting a shift from acute to chronic disease paradigm
• World Health Organization: Defines health to include physical, mental, and social well-being; evolved definition emphasizes an individual's ability to cope and realize aspirations despite disease
• Cancer literature: Demonstrated that direct patient collection of AEs yields more accurate signals than clinician-filtered reporting, supporting the PRO-CTCAE framework

4. Practical Takeaways for Clinicians

• Recognize care gaps in episodic chronic disease management: The illustrative case of a cirrhotic patient (a nurse) who deteriorated physically, nutritionally, and socially over a 3-month gap between visits underscores the limitations of clinic-only, episodic follow-up
• Integrate PROs into routine outpatient monitoring: Structured, validated PRO collection between visits can identify declines in QoL, functional status, and social well-being that are otherwise missed
• Do not rely solely on disease surrogates or survival endpoints: Markers such as MELD score do not capture what matters most to patients — their day-to-day functioning and well-being
• Embrace digital health tools: Expanding digital platforms offer the infrastructure for continuous PRO monitoring, enabling a shift from reactive episodic care to proactive, continuous, patient-centered care
• Use validated, patient-direct instruments: Ensure PRO tools are psychometrically validated
