1.2 Healthcare Systems and Settings
Key Takeaways
- Healthcare delivery settings include hospitals, ambulatory care clinics, urgent care centers, physician offices, long-term care facilities, and home health agencies
- The healthcare team includes physicians, physician assistants, nurse practitioners, registered nurses, licensed practical nurses, medical assistants, and allied health professionals
- Medical assistants work under the supervision of a physician or other licensed provider and cannot independently diagnose, prescribe, or perform surgery
- Scope of practice for MAs varies by state but generally includes taking vital signs, preparing patients, assisting with procedures, performing basic lab tests, and administrative tasks
- Quality improvement programs like HEDIS, PCMH, and CMS quality measures are used to evaluate and improve healthcare delivery
- The Patient-Centered Medical Home (PCMH) model emphasizes coordinated, team-based care with the patient at the center

Healthcare Systems and Settings
Medical assistants work in a variety of healthcare settings, each with different organizational structures, patient populations, and expectations. Understanding these settings and your role within the healthcare team is foundational knowledge tested on the CCMA exam.
Healthcare Delivery Settings
| Setting | Description | MA Role |
|---|---|---|
| Physician office | Private practice (solo or group), most common MA workplace | Full clinical and administrative duties |
| Ambulatory care clinic | Outpatient clinic, may be hospital-affiliated | Clinical procedures, patient intake, vitals |
| Urgent care center | Walk-in clinic for non-emergency acute conditions | Fast-paced triage, vitals, procedures |
| Hospital outpatient dept | Hospital-based clinics for specialty care | Assist with procedures, patient prep |
| Community health center | Federally qualified health centers (FQHCs) serving underserved populations | Full scope MA duties, patient education |
| Specialty practice | Cardiology, dermatology, orthopedics, etc. | Specialty-specific procedures (EKGs, biopsies) |
| Long-term care facility | Nursing homes, rehabilitation centers | Limited MA role; more CNA/LPN-focused |
| Home health agency | Healthcare delivered in patient's home | Rare for MAs; more for RNs and home health aides |
| Telehealth | Virtual patient encounters via technology | Patient check-in, vital signs documentation, tech support |
The Healthcare Team
| Role | Credential | Scope |
|---|---|---|
| Physician (MD/DO) | Medical degree + residency | Full scope: diagnose, prescribe, perform surgery |
| Physician Assistant (PA-C) | Master's degree | Diagnose, prescribe, treat under physician collaboration |
| Nurse Practitioner (NP) | Master's/doctoral nursing degree | Diagnose, prescribe, treat (scope varies by state) |
| Registered Nurse (RN) | BSN or ADN + NCLEX-RN | Assess, plan care, administer medications, educate |
| Licensed Practical Nurse (LPN) | LPN program + NCLEX-PN | Basic nursing care under RN/physician supervision |
| Medical Assistant (MA) | Training program + certification | Clinical and administrative tasks under physician supervision |
| Phlebotomist | Phlebotomy program + certification | Blood collection and specimen processing |
| Medical Laboratory Technician | Associate degree + certification | Perform and analyze laboratory tests |
| Radiology Technologist | Associate/bachelor's + certification | Perform diagnostic imaging procedures |
| Physical Therapist | Doctoral degree (DPT) | Evaluate and treat movement disorders |
| Pharmacist | Doctoral degree (PharmD) | Dispense medications, counsel patients |
Medical Assistant Scope of Practice
The MA scope of practice is defined by state law and employer policy. MAs work under the direct or general supervision of a licensed provider.
Medical Assistants CAN:
- Take and record vital signs
- Prepare patients for examination
- Assist the provider during examinations and procedures
- Perform phlebotomy and collect specimens
- Perform basic laboratory tests (CLIA-waived)
- Administer medications and injections as directed
- Perform EKGs
- Apply dressings and remove sutures/staples (as directed)
- Provide patient education as directed by the provider
- Schedule appointments, manage medical records, process insurance claims
Medical Assistants CANNOT:
- Independently diagnose conditions
- Prescribe medications
- Perform surgery
- Interpret diagnostic test results (report only)
- Practice independently without physician supervision
- Perform procedures outside their training and competency
- Triage patients in the emergency department (RN role)
- Administer IV medications in most states
Quality Improvement in Healthcare
Quality improvement (QI) is an ongoing process to improve patient care, safety, and outcomes. Medical assistants participate in QI activities in their practices.
Key Quality Frameworks:
| Framework | Description | Relevance to MAs |
|---|---|---|
| PCMH (Patient-Centered Medical Home) | Team-based care model with the patient at the center; emphasizes access, coordination, and quality | MAs are key team members in PCMH practices |
| HEDIS (Healthcare Effectiveness Data and Information Set) | Performance measures used by health plans to evaluate quality of care | MAs collect data for HEDIS measures (screenings, immunizations) |
| CMS Quality Measures | Medicare/Medicaid quality reporting programs | MAs ensure documentation supports quality reporting |
| PDSA Cycle | Plan-Do-Study-Act — iterative improvement method | MAs participate in testing and implementing improvements |
| Root Cause Analysis | Systematic investigation of adverse events | MAs may provide information about incidents |
The PDSA Cycle:
- Plan — Identify the problem and develop a change to test
- Do — Implement the change on a small scale
- Study — Analyze the results; did the change improve outcomes?
- Act — Adopt, adapt, or abandon the change based on results
Healthcare Documentation Standards
| Standard | Description |
|---|---|
| SOAP notes | Subjective, Objective, Assessment, Plan — standard documentation format |
| EHR/EMR | Electronic Health/Medical Record — digital patient records |
| Meaningful Use | Federal program promoting EHR adoption and interoperability |
| Interoperability | Ability of different EHR systems to share patient data |
| HL7 / FHIR | Standards for healthcare data exchange between systems |
SOAP Note Components:
- S (Subjective): What the patient reports — symptoms, concerns, history
- O (Objective): What you observe and measure — vital signs, exam findings, test results
- A (Assessment): Provider's diagnosis or clinical impression
- P (Plan): Treatment plan — medications, procedures, follow-up, referrals
Medical assistants primarily contribute to the S (documenting patient-reported information during intake) and O (recording vital signs, test results) components.
