MHA 708 Comprehensive Study Guide
1 Artificial Intelligence in U.S. Health-Care Delivery
• Purpose of AI: apply machine learning (ML) and natural language processing (NLP)
to complex clinical data to improve quality, safety, outcomes, efficiency and
access. AI can interpret unstructured notes (NLP) and find patterns (ML) instead of
relying on static rules.
• Drivers: explosion of medical knowledge (doubles every 75 days), COVID-19
accelerating digital adoption and clinician shortages.
• High-value domains (mnemonic R- C- Q):
1. Reimbursement: predictive analytics reduce claim denials by ~33 % and
administrative costs by 30 %.
2. Clinical operations: AI for operating room scheduling and capacity
management increases utilization 15–20 %; NLP speeds documentation and
reduces burnout.
3. Quality S safety: monitors adverse events, predicts complications and
analyzes patient experience.
• Challenges: few randomized trials, workflow integration barriers, privacy and bias
concerns.
2 Health Insurance and the Promise of Incrementalism
• Study: Women’s Interagency HIV Study (2005–2014) examined insurance
interruption and hypertension control.
• Findings: continuous insurance improves chronic disease control; interruptions
raise the risk of losing hypertension control. Women without HIV experienced twice
the interruption rate (7.6 vs. 3.4 per 100 person-years). The AIDS Drug
Assistance Program (ADAP) served as a functional equivalent of insurance for
HIV-positive women.
• Implications: incremental, continuous care improves outcomes for chronic
diseases (hypertension, diabetes, opioid use disorder). Cost-sharing policies (higher
copays) reduce routine care but increase hospitalizations—every $1 saved adds $6
in hospital costs. Long-term follow-up is needed to assess policies.
• Memory trick: HIC = Health-insurance continuity → Incremental care → improved
Chronic disease control.
3 An Overview of Medicare (Mnemonic ABCD)
• Definition: federal insurance for people ≥65 years, certain disabled individuals and
those with end-stage renal disease

, • Part A – Hospital insurance: covers inpatient hospital, skilled nursing and hospice
care. Premium-free if you paid Medicare taxes ≥10 years.
• Part B – Medical insurance: physician services, outpatient care and preventive
services; funded by premiums and 20 % coinsurance.
• Part C – Medicare Advantage: private plans combining Parts A and B (often D)
with extra benefits.
• Part D – Prescription drugs: offered by private insurers; premiums plus federal
subsidy.
• Key facts: financed by payroll taxes, general revenue and premiums. The Part A
trust fund may become insolvent in the mid-2030s without reforms. Beneficiaries
often purchase Medigap policies to cover out-of-pocket costs. Medicare
(age/disability-based) differs from Medicaid (income-based, joint federal–state).
4 Quality Measurement
4.1 Health-Care Value Equation
• Formula: Value = (Quality + Service) ÷ Cost × Appropriateness.
• Components:
– Quality – outcomes such as survival, functional status and patient experience.
– Service – patient-centered interactions, compassion and communication.
– Cost – direct and indirect expenses.
– Appropriateness – right place, time, patient and context.
• Implications: increasing Quality or Service (with constant Cost) raises Value;
increasing Cost (holding Quality/Service constant) lowers Value. Even high-quality
services reduce value if they are inappropriate for the patient.
4.2 Purposes of Quality Measures
• Evaluation S benchmarking – compare performance against standards or peers.
• Comparison of different interventions, providers or groups.
• Monitoring change over time (trend analysis).

, • Identify substandard or exceptional performance, enabling best-practice
dissemination and pay-for-performance incentives.
• Inform patient choice and certify that individuals/organizations meet standards.
• Highlight best practices, monitor improvement and address community health
needs.
4.3 Institute of Medicine (IOM) Six Aims – STEEEP
1. Safe: First, do no harm.
2. Timely: reduce wait times and delays.
3. Effective: base care on scientific evidence; avoid underuse and misuse.
4. Efficient: eliminate waste (supplies, time, energy).
5. Equitable: consistent quality regardless of gender, ethnicity, location or
socioeconomic status.
6. Patient-centered: respect individual preferences, needs and values – decisions
should align with patient values..
4.4 AHRQ’s 13 Characteristics of Effective Quality Measures
Mnemonic STARE-R² EVERS helps recall these features:
• Standardized – everyone measures the same way.
• Timely – results available when needed.
• Available – accessible to those being measured, transparent.
• Reliable – repeatable without random error.
• Evidence-based – grounded in science linking structure/process to outcomes.
• Relevant – important to patients, providers, payers and policymakers.
• Evaluability – allows assessing better vs. worse performance, not just differences.
• Validity – actually measures the desired concept (veracity).
• Experience – reflects actual performance (data collection glitches minimized).
