Patient Safety & Systems-Based Practice

Care coordination and patient-centered medical home

Clinical Overview and When to Suspect Care Coordination Gaps

— Five core functions per AHRQ: comprehensive care, patient-centered, coordinated care, accessible services, quality & safety.

— Recognized by NCQA, Joint Commission, URAC, and AAAHC; aligns with CMS value-based payment (MIPS, ACO REACH, Primary Care First).

— Patient with multiple chronic conditions (DM + CHF + CKD) presenting with duplicated labs, conflicting medication lists, or missed specialist follow-up.

— Recent hospital discharge with 30-day readmission, no PCP visit, unreconciled meds.

— ED "frequent flyer" with ambulatory-care-sensitive conditions (asthma exacerbation, hyperglycemia, CHF).

— Elderly patient on >5 medications from >3 prescribers (polypharmacy red flag).

— Limited English proficiency, low health literacy, or social determinants barriers (housing, transport).

Patient-Centered Medical Home (PCMH) is a primary care delivery model emphasizing comprehensive, team-based, coordinated, accessible care with measurable quality and safety.

Care coordination = deliberate organization of patient activities between ≥2 participants (including the patient) to facilitate appropriate health care delivery. It is the operational glue of PCMH.

When to suspect coordination failure in a Step 3 stem:

High-risk transitions = hospital→home, hospital→SNF, ED→home, ICU→ward, pediatric→adult care. Each is a documented patient safety hazard.

Step 3 management: When a stem presents a recently discharged complex patient with a new symptom, the correct first action is often medication reconciliation and a structured post-discharge visit within 7–14 days, not immediate re-hospitalization or new specialist referral.

Board pearl: PCMH is not a building or a physical home — it is a model of primary care delivery. The "home" is the relationship and the coordinating team, not a place. Expect distractors framing PCMH as a facility or as a capitated insurance product.

Presentation Patterns and Key History

— "A 72-year-old discharged 5 days ago for CHF exacerbation returns to ED with dyspnea; he is unsure which of his two furosemide bottles to take."

— "A 58-year-old diabetic sees endocrinology, nephrology, podiatry, and ophthalmology; his HbA1c is 10.4% and no one has adjusted his insulin."

— "A teen with sickle cell disease aging out of pediatric care has missed three adult hematology appointments."

— Medication reconciliation: name, dose, indication, who prescribed, adherence, OTC/supplements.

— Recent transitions: hospitalizations, ED visits, SNF stays, new consultants in last 90 days.

— Functional status & caregiver: who manages pillbox, transportation, food security.

— Advance care planning: code status, surrogate, POLST/MOLST if applicable.

— Social determinants: housing stability, insurance, language, literacy — screen with tools like PRAPARE or AHC-HRSN.

— Behavioral health: PHQ-2/PHQ-9, GAD-7, AUDIT-C — embedded screening is a PCMH hallmark.

— Duplicate imaging/labs across systems.

— Conflicting anticoagulation instructions from cardiology vs PCP.

— No documented PCP in EMR despite chronic disease.

— Patient cannot name a "main doctor."

Care coordination questions rarely present as "the patient has X disease." Instead the stem describes a system failure:

Key history elements the examinee must elicit (or recognize were missed):

Red-flag patterns suggesting coordination breakdown:

Key distinction: A patient with poorly controlled diabetes due to nonadherence from cost is a coordination/social-needs problem (refer to care manager, pharmacist, patient assistance programs) — not a medication titration problem first. Step 3 frequently tests recognition that the next best step is addressing the system barrier, not escalating pharmacotherapy.

Board pearl: A patient who says "I just go wherever they send me" is signaling absence of a medical home — the correct intervention is empanelment to a primary care team.

Team Structure and Roles (the "Exam Equivalent" of Physical Exam)

— PCP / lead clinician: longitudinal accountability, panel ownership.

— RN care manager: high-risk patient outreach, chronic disease coaching, transition calls.

— Clinical pharmacist: medication reconciliation, MTM (Medication Therapy Management), deprescribing.

— Behavioral health integration (BHI): warm handoff, collaborative care model (psychiatrist consultant + care manager + PCP) — only evidence-based model with Medicare CPT codes (99492–99494).

— Social worker / community health worker: SDOH navigation, benefits enrollment.

— Medical assistant: rooming, standing orders (immunizations, A1c), pre-visit planning.

— Patient navigator: cancer screening completion, specialty referral closure.

In PCMH, the "exam" is assessing the care team and workflow rather than the patient's body. Know the roles:

Empanelment: every patient assigned to a specific provider/team — the structural basis of accountability and continuity. Continuity correlates with lower mortality, fewer ED visits, lower cost.

Huddles: brief daily team meetings to review the day's panel — a Step 3 patient safety construct (anticipates risk before the visit).

Pre-visit planning: labs drawn before the appointment so results drive the visit (e.g., A1c on day of diabetes follow-up).

Population health registry: list of all panel patients with diabetes, CHF, etc., used to identify care gaps (overdue A1c, missing pneumococcal vaccine).

Step 3 management: When a stem asks "best way to ensure all diabetic patients in the practice receive annual retinal screening," answer is population registry with outreach, not opportunistic in-visit reminders.

Board pearl: The collaborative care model for depression in primary care has the strongest RCT evidence of any integrated behavioral intervention — beats referral-out, beats screening alone. Recognize it by the measurement-based care + psychiatric consultant + care manager triad.

Diagnostic Workup — Identifying Care Gaps and Risk Stratification Tools

— HEDIS measures: standardized quality metrics (e.g., CBP, CDC-A1c<8, BCS, CCS, COL, IMA). Used by NCQA, Medicare Stars, commercial payers.

— Care gap reports: registry-driven lists of overdue services per patient.

— Risk stratification: tiering panel into low/moderate/high/very high complexity using tools such as CMS HCC (Hierarchical Condition Category), AAFP risk model, or LACE+ index for readmission risk.

— Length of stay, Acuity of admission, Comorbidity (Charlson), Emergency visits in prior 6 mo. Score ≥10 = high risk → intensive transition support.

— HOSPITAL score, 8Ps tool (Project BOOST) for transitions.

— PHQ-9, GAD-7, AUDIT, DAST-10 for behavioral comorbidity.

— Morisky-8 or single-item adherence question.

— Health literacy: REALM-SF, Newest Vital Sign.

PCMH "diagnostics" = systematic measurement of care quality and risk:

LACE index (predicts 30-day readmission/death):

Other validated tools:

Medication reconciliation at every transition is the single highest-yield "diagnostic" step — discrepancies occur in ~50% of post-discharge patients.

Annual Wellness Visit (AWV) for Medicare: required HRA, cognitive screen, fall risk, depression, advance care planning — a billable PCMH touchpoint (G0438 initial, G0439 subsequent).

CCS pearl: On inpatient CCS cases, ordering "medication reconciliation" at admission and again at discharge is rewarded — and forgetting it before discharge is a common point loss. Always pair discharge with "follow-up with PCP in 7 days" for high-risk patients.

Board pearl: The strongest evidence-based bundle to reduce 30-day readmissions is the Care Transitions Intervention (Coleman) or Project RED — features include patient-centered discharge record, post-discharge phone call within 72h, and follow-up visit within 7–14 days.

Advanced Tools — Health IT, HIE, and Closed-Loop Referrals

— Problem list, medication list, allergy list — structured and reconciled.

— Clinical decision support (CDS) with alerts for drug-drug interactions, care gaps.

— Patient portal with secure messaging, lab release, visit summaries (Cures Act information blocking rules apply).

— e-prescribing including controlled substances (EPCS), with PDMP query.

Electronic Health Record (EHR) capabilities required for PCMH recognition:

Health Information Exchange (HIE): bidirectional data flow across organizations; ADT (admit-discharge-transfer) notifications push real-time alerts to the PCP when their patient hits an ED or hospital — foundational for post-discharge outreach.

Closed-loop referrals: PCP sends referral with question and records, specialist sees patient and returns consult note, PCP acknowledges and integrates plan. Most referrals are NOT closed-loop — a major safety gap.

Care plans: shared, accessible document for complex patients; required element for Chronic Care Management (CCM) billing — CPT 99490 (≥20 min/month non-face-to-face care coordination for ≥2 chronic conditions expected to last ≥12 months).

Principal Care Management (PCM) CPT 99424–99427: single high-risk condition.

Transitional Care Management (TCM) CPT 99495/99496: post-discharge — requires contact within 2 business days and face-to-face visit within 7 or 14 days depending on complexity.

Remote Patient Monitoring (RPM) CPT 99453–99458: BP cuffs, glucometers, weight scales transmitting data.

Step 3 management: A patient discharged after CHF exacerbation should be enrolled in TCM with visit ≤7 days (high complexity), daily weights with RPM, and CCM thereafter for ongoing coordination.

Board pearl: Information blocking under the 21st Century Cures Act generally requires release of test results to patients without delay, even before the clinician reviews them, with limited exceptions (e.g., risk of harm). Expect a stem on releasing biopsy results to a portal.

Risk Stratification and Tiered Care Management Logic

— Tier 1 (healthy, ~50%): preventive care, screening per USPSTF, immunizations, AWV.

— Tier 2 (1–2 stable chronic conditions, ~30%): registry-based recall, self-management support, MA-driven standing orders.

— Tier 3 (multiple chronic conditions, moderate complexity, ~15%): enroll in CCM, pharmacist MTM, behavioral health integration.

— Tier 4 (very high complexity, frail, recent hospitalization, ~5%): intensive RN care management, home visits, palliative care consult, advance care planning.

PCMH care intensity should match patient complexity — population segmentation drives resource allocation:

Hot-spotter / super-utilizer = top 5% by cost/utilization (often >$50K/yr). Mixed evidence on intensive interventions (Camden Coalition RCT was negative for readmissions — recognize this nuance).

Social risk integration: stratify also by SDOH — food insecurity, housing, transportation. Use Z-codes (Z55–Z65) for ICD-10 documentation; required for risk-adjusted payment models.

Behavioral health stratification: PHQ-9 ≥10 or GAD-7 ≥10 → collaborative care; suicidal ideation → safety planning and same-day evaluation.

Frailty: Clinical Frailty Scale, gait speed <0.8 m/s — triggers deprescribing review and goals-of-care conversation.

CCS pearl: For a stem describing a frail 84-year-old on 14 medications including 2 anticholinergics and a benzodiazepine, the next best step is comprehensive medication review and deprescribing (Beers/STOPP criteria) — not adding another agent for symptoms.

Board pearl: Risk stratification is dynamic — re-tier after every hospitalization, new diagnosis, or major life event. A previously tier-2 patient who is hospitalized for sepsis becomes tier 3–4 for the next 90 days and should receive enhanced surveillance.

Core Interventions — Transitions of Care Bundle

— Medication self-management (patient knows what, why, when).

— Patient-centered health record (portable, updated).

— Follow-up with PCP/specialist.

— Knowledge of red flags and how to respond.

— Medication reconciliation with indication for each drug.

— Teach-back with patient/caregiver in preferred language (use certified medical interpreter, not family).

— Written discharge instructions at 5th-grade reading level.

— Follow-up appointment scheduled before discharge (not "call to schedule").

— Direct communication (phone, secure message, shared EHR note) PCP-to-hospitalist within 24h.

— Pending labs and tests explicitly listed with responsible clinician.

— DME, home health, hospice referrals placed and confirmed.

— Post-discharge phone call within 48–72h by RN/pharmacist.

Evidence-based Care Transitions Intervention (Coleman model) — 4 pillars:

Project RED (Re-Engineered Discharge) — 12 components including discharge advocate, after-hospital care plan booklet, pharmacist call 2–4 days post-discharge.

Operational discharge bundle (CCS-ready order set):

Transitional Care Management billing rewards completing this bundle: face-to-face within 7 days = 99496 (high complexity) or 14 days = 99495 (moderate); plus contact within 2 business days.

Pharmacy interventions reduce ADEs: clinical pharmacist post-discharge review cuts readmissions in select populations (CHF, anticoagulation).

Step 3 management: Patient discharged on warfarin after PE — the next best step before discharge is arranging INR check within 3–5 days and confirming anticoagulation clinic enrollment, not handing the patient a lab slip "sometime next week."

Board pearl: Teach-back ("Can you tell me in your own words how you'll take this medicine?") is the highest-yield health literacy tool — it identifies misunderstanding before the patient leaves.

Advanced Coordination — Chronic Care, Behavioral Health Integration, and Payment

— Eligibility: ≥2 chronic conditions expected ≥12 months with significant risk of decompensation.

— Requires: patient consent (verbal or written), comprehensive care plan, 24/7 access, designated care team, ≥20 min/month non-face-to-face time.

— Triad: PCP + behavioral health care manager + psychiatric consultant (curbside, doesn't see patient).

— Measurement-based care (PHQ-9 tracked), stepped care (escalate if not improving in 10–12 weeks), registry-based.

— Reduces depression severity vs usual care in multiple RCTs (IMPACT trial).

— MIPS (Merit-based Incentive Payment System): Quality, Cost, Improvement Activities, Promoting Interoperability.

— MSSP ACOs, ACO REACH, Primary Care First, Making Care Primary.

— PCMH recognition earns automatic Improvement Activity credit and bonus points.

Chronic Care Management (CCM) CPT 99490 / 99439 / 99487 / 99489:

Behavioral Health Integration — Collaborative Care Model (CoCM) CPT 99492/99493/99494:

General BHI CPT 99484 (≤20 min/month, no psychiatric consultant required).

Value-based payment alignment:

PMPM (per member per month) care management fees supplement FFS to fund care coordinators.

Hierarchical Condition Categories (HCC) — accurate documentation of chronic conditions drives risk-adjusted payment; under-documentation underfunds the panel.

Step 3 management: When a stem describes a depressed diabetic with PHQ-9 of 15 who declines psychiatry referral, the best next step is enrollment in collaborative care within primary care — improves both depression and A1c.

Board pearl: Recognize CoCM by its three components. If any is missing (e.g., no psychiatric consultant, or no registry tracking), it is not true collaborative care and won't earn the CPT — and won't show the same outcomes on the exam.

Special Populations — Elderly, Polypharmacy, and Renal/Hepatic Impairment

— Beers Criteria (AGS): avoid in older adults — long-acting benzodiazepines, anticholinergics (diphenhydramine, oxybutynin), TCAs, sliding-scale insulin alone, NSAIDs chronically, PPIs >8 weeks without indication.

— STOPP/START criteria: complementary European tool — STOPP lists drugs to stop, START lists evidence-based drugs to add (e.g., statin in elderly diabetic).

— Adjust gabapentin, metformin (hold if eGFR <30), DOACs (apixaban dose reduction criteria: age ≥80, weight ≤60 kg, Cr ≥1.5 — any 2 of 3).

— Avoid NSAIDs, nitrofurantoin if CrCl <30, contrast judiciously.

Geriatric care coordination priorities ("5 Ms"): Mind, Mobility, Medications, Multicomplexity, Matters most.

Polypharmacy: ≥5 chronic medications. Each additional drug increases ADE, falls, delirium, and nonadherence risk.

Deprescribing workflow: review indication → assess benefit/harm → taper if needed → monitor.

Falls risk: ask annually about falls; if yes or gait abnormality → multifactorial assessment, vitamin D, PT, vision check, med review, home safety.

Cognitive screening: Mini-Cog, MoCA at AWV; abnormal → dementia workup and ACP.

Renal impairment (CKD):

Hepatic impairment: avoid acetaminophen >2 g/day in severe disease, dose-adjust statins, avoid valproate, watch INR with antibiotics.

CCS pearl: In an elderly inpatient case, ordering a comprehensive geriatric assessment, PT/OT evaluation, medication reconciliation with deprescribing, and home health referral before discharge are reliable point earners.

Board pearl: A new fall in an elderly patient on a benzodiazepine is the benzodiazepine's fault until proven otherwise — the next best step is taper/discontinue, not workup for syncope first (unless red flags like LOC or chest pain).

Special Populations — Pediatric-to-Adult Transitions, Pregnancy, and Underserved

— Bright Futures schedule guides preventive visits and screening (autism at 18/24 mo, developmental at 9/18/30 mo, depression annually 12+, HIV once 15–18).

— Transition policy, tracking & monitoring, readiness assessment (TRAQ), planning, transfer of care, transfer completion.

— Begin at age 12–14, formal transfer typically 18–22, especially critical in CF, sickle cell, congenital heart disease, IBD, type 1 DM, autism, intellectual disability.

— Co-management between OB and PCP for chronic conditions (DM, HTN, depression, thyroid).

— Postpartum visit recommended within 3 weeks, comprehensive visit by 12 weeks (ACOG) — old "6-week" standard is outdated.

— Postpartum depression screening (EPDS or PHQ-9) at all postpartum and well-child visits.

— Interpregnancy care: optimize chronic conditions, fold in WIC, lactation, contraception.

— Language: professional interpreters required under Title VI; family/minors as interpreters is a safety/ethics violation.

— Refugee/immigrant: domestic medical exam, TB and parasite screening, mental health.

— Justice-involved: Medicaid suspension (not termination) reinstatement at release; high overdose risk 2 weeks post-release → naloxone, MOUD bridge.

Pediatric medical home (AAP/AAFP/ACP joint principles 2007 — origin of modern PCMH): family-centered, culturally effective, continuous care from birth.

Health care transition (HCT) from pediatric to adult care — Got Transition / Six Core Elements:

Pregnancy coordination:

Underserved populations:

Step 3 management: A 19-year-old with sickle cell aging out of pediatrics needs a structured transfer with warm handoff to adult hematology, transfer summary, and confirmed first adult visit before pediatric discharge — not a referral letter alone.

Board pearl: Postpartum follow-up has moved to a multivisit paradigm starting at 3 weeks — answer choices with "6-week postpartum visit only" are wrong on current exams.

Complications of Poor Coordination — Adverse Outcomes

— Highest-risk drugs: anticoagulants, insulin/hypoglycemics, opioids, digoxin, antiplatelets.

— Duplicate testing (radiation, cost, false positives).

— Conflicting recommendations from multiple specialists.

— Polypharmacy and drug-drug interactions.

— Lost referrals — up to 50% never completed.

Adverse drug events (ADEs) are the most common post-discharge harm — ~20% of patients within 3 weeks of hospital discharge; ~⅔ preventable or ameliorable.

Hospital readmissions: ~15% of Medicare admissions readmitted within 30 days; CMS Hospital Readmissions Reduction Program (HRRP) penalizes excess readmissions for AMI, HF, pneumonia, COPD, CABG, hip/knee arthroplasty.

Diagnostic errors in transitions: missed test follow-up (pending labs at discharge, incidental findings on imaging) — leading source of outpatient malpractice claims.

Fragmentation harms:

Patient experience harm: lower trust, lower adherence, lower satisfaction (CAHPS scores tied to payment).

Equity harms: minoritized, low-English-proficiency, and rural patients disproportionately experience coordination failures and worse outcomes.

Caregiver burden: unpaid family caregivers absorb coordination gaps — burnout, depression, financial strain. Screen with Zarit Burden Interview.

Provider burnout: poor coordination drives EHR inbox overload, after-hours work ("pajama time"), and attrition — a systems-level patient-safety threat.

CCS pearl: A patient discharged with pending blood cultures that later grow MRSA represents a failure to close the loop. The system fix is automated result-routing to a designated clinician with acknowledgment required, not blaming the individual.

Board pearl: The most common reason for 30-day readmission after CHF discharge is medication nonadherence and inadequate follow-up — both addressable by transitional care, not by escalating diuretics.

When to Escalate — Care Management Intensity and Hospital-Level Decisions

— New tier-4 status (hospitalization, ICU stay, new cancer dx, advanced HF, frailty) → intensive RN care management within 48 hours.

— PHQ-9 ≥20 or suicidal ideation → same-day behavioral health evaluation; if active plan/intent → ED.

— Uncontrolled chronic disease despite stepped therapy → specialist referral with closed-loop expectations.

— Caregiver collapse → social work, respite, possible higher level of care.

— Hospital at Home (CMS Acute Hospital Care at Home waiver).

— Home health (skilled nursing, PT/OT, home infusion).

— Community paramedicine, mobile integrated health.

— Palliative care home visits; hospice if prognosis ≤6 months and goals align.

— Ambulatory-care-sensitive condition (asthma, CHF, DM) without red flags → urgent PCP slot, telehealth, or RN care manager — not ED.

— Red flags (hemodynamic instability, severe pain, neuro deficit, sepsis criteria) → ED.

— Social admit (unsafe home, caregiver failure) → care management + community resources; admit only if medically indicated.

Escalation triggers within PCMH:

Home-based options (avoid hospitalization when feasible):

Outpatient vs ED vs admit logic for the Step 3 stem:

Specialist referral: include question, relevant records, and clear handoff back. eConsults (asynchronous specialist input) reduce face-to-face referrals and improve access — Step 3 may test this as a high-value option.

Step 3 management: A diabetic with A1c 9.2% on maximal oral therapy whose barrier is cost and injection fear — the next step is integrated pharmacist/diabetes educator within the PCMH, not immediate endocrinology referral.

Board pearl: Hospital at Home programs deliver acute-level care (IV abx, telemetry, daily clinician visit) safely for selected CHF, COPD, cellulitis, and pneumonia patients — recognize as appropriate alternative when offered.

Key Differentials — Distinguishing Coordination Models

— PCMH: primary care practice-level model focused on care delivery (the building block).

— ACO (Accountable Care Organization): network of providers/hospitals assuming shared accountability for cost & quality of an attributed population (the umbrella).

— Medical Neighborhood: PCMH + specialists + hospitals + community resources working with defined care compacts.

— Health Home (Medicaid Section 2703): for patients with serious mental illness or chronic conditions, emphasizing behavioral-medical integration; not the same as PCMH despite the name.

— DPC = membership fee, smaller panels, no insurance billing. Some DPCs meet PCMH criteria; many do not (lack registry, BHI, formal quality reporting).

— Old HMO gatekeeping was access-restriction. PCMH is care-coordination — opposite philosophy though both involve a primary care anchor.

— FQHC is a funding/regulatory designation (Section 330) for safety-net care; many FQHCs are PCMH-recognized, but the categories are independent.

— Co-location = same building. Collaborative Care = same building plus care manager + registry + psychiatric consultant + measurement-based stepped care. Co-location alone does not equal CoCM.

PCMH vs ACO vs Medical Neighborhood vs Health Home — frequently confused:

PCMH vs Concierge / Direct Primary Care (DPC):

PCMH vs Capitation / HMO gatekeeping:

PCMH vs FQHC (Federally Qualified Health Center):

Collaborative Care vs co-located behavioral health:

Key distinction: PCMH is a delivery model; ACO is a payment/accountability model. A single practice can simultaneously be a PCMH and participate in an ACO — they are complementary layers, not alternatives.

Board pearl: When a question describes "shared savings for a population of Medicare beneficiaries," that is ACO. When it describes "team-based primary care with registry and care coordinator," that is PCMH.

Key Differentials — Other Quality and Safety Frameworks

— Triple: better care, better health, lower cost.

— Quadruple: + clinician well-being.

— Quintuple: + health equity (Itchhaporia/NEJM 2022).

Quadruple / Quintuple Aim (vs original Triple Aim):

Chronic Care Model (Wagner) — predecessor framework with 6 elements: health system, delivery system design, decision support, clinical information systems, self-management support, community resources. PCMH operationalizes this.

Lean / Six Sigma / PDSA cycles: quality improvement methodologies used within PCMH — not alternatives to it.

Root cause analysis (RCA): retrospective tool after a sentinel event; Failure Mode and Effects Analysis (FMEA): prospective tool to anticipate failure modes (e.g., before launching a new referral workflow).

Just Culture: balances accountability (reckless behavior disciplined) with system focus (human error addressed by redesign, at-risk behavior coached). Replaces older "blame and shame" model.

Patient safety event categories (NCC MERP): A (capacity to cause error) through I (death). Near-misses (B-D) should be reported as eagerly as harm events for system learning.

High-reliability organization (HRO) principles: preoccupation with failure, reluctance to simplify, sensitivity to operations, commitment to resilience, deference to expertise.

Patient and Family Advisory Councils (PFACs): structural patient voice in PCMH governance — required for some recognition levels.

Step 3 management: After a medication error reaches a patient without harm (Category D), the correct action is non-punitive event reporting and system-level RCA, not individual discipline — unless the act was reckless under Just Culture.

Board pearl: Equity is now an explicit Aim — expect questions where the "best" answer includes a population-level disparities lens (e.g., A1c control gap between English- and Spanish-speaking patients → bilingual diabetes educator and culturally tailored materials).

Long-Term Plan — Embedding Coordination as the Standard

— Pre-visit planning with labs drawn 1–2 weeks ahead.

— Standing orders for nurses/MAs (immunizations, A1c, BP rechecks, foot exams).

— Group visits / shared medical appointments for diabetes, prenatal, behavioral conditions.

— Patient self-management goals documented and revisited (SMART goals).

— Population registries reviewed monthly with outreach to gaps.

— Post-MI: statin, β-blocker, ACEi/ARB, antiplatelet, cardiac rehab referral, BP/lipid/A1c targets.

— Post-stroke: antiplatelet or anticoagulant per etiology, statin, BP control <130/80, smoking cessation, rehab.

— Post-cancer survivorship plan: surveillance schedule, late-effects monitoring, psychosocial support.

Sustained PCMH practice features for chronic disease management:

Preventive services delivery per USPSTF Grade A/B + ACIP immunizations + Bright Futures: should approach >80–90% on HEDIS measures for high-performing PCMHs.

Secondary prevention examples managed in PCMH:

Advance care planning revisited at every transition; document MOLST/POLST, surrogate, code status. Bill CPT 99497/99498 for ACP discussions.

Self-management support: motivational interviewing, action plans (asthma, CHF), patient activation measure (PAM).

Step 3 management: A patient with stage 3 CKD due to diabetes + HTN belongs in a coordinated longitudinal plan including SGLT2 inhibitor (renal protection), ACEi/ARB, BP <130/80, A1c individualized 7–8%, statin, annual UACR and eGFR, vaccinations, nephrology co-management when eGFR <30 or rapidly declining — all anchored in PCMH.

Board pearl: Cardiac rehabilitation referral at discharge post-MI/CABG/HF is a HEDIS and Class I guideline measure — frequently the "missed" PCMH action in stems and a high-value answer choice.

Follow-Up, Monitoring, and Counseling Cadence

— Post-hospital discharge (high-risk): PCP visit within 7 days, phone within 48–72 h.

— Post-MI: 2–6 weeks, then 3–6 months, then annually with risk-factor labs.

— New HTN starting medication: 2–4 weeks for BP recheck; once at goal, every 3–6 months.

— Diabetes: every 3 months if not at A1c goal; every 6 months if stable.

— CKD stages 3–4: every 3–6 months with eGFR, UACR, K, bicarbonate.

— Depression on new SSRI: contact within 1–2 weeks, visit at 4–6 weeks with PHQ-9, response check at 6–8 weeks, remission goal by 10–12 weeks.

— Anticoagulation: warfarin INR per stability; DOAC annual review of renal function and adherence.

— Postpartum: 3 weeks initial, comprehensive by 12 weeks.

— Pediatric well-child: Bright Futures schedule.

— Medicare AWV: annually.

— Documented targets, who is responsible, what to do if out of range.

— RPM data review intervals (CPT 99457 requires ≥20 min/month interactive).

— Tobacco (5 A's: Ask, Advise, Assess, Assist, Arrange), USPSTF Grade A.

— Alcohol/unhealthy substance use (USPSTF Grade B brief counseling).

— Weight management (intensive behavioral intervention for BMI ≥30).

— Sexual health, contraception, PrEP/PEP, STI screening.

— Falls, home safety, driving safety in elderly.

Standard follow-up intervals (Step 3 expects these):

Monitoring parameters in coordinated care plans:

Counseling embedded in PCMH:

CCS pearl: Always order "schedule follow-up appointment" explicitly on CCS — and tie it to the right interval. Missing it loses points even when management is otherwise correct.

Board pearl: Cardiac rehab, pulmonary rehab, and supervised exercise therapy for PAD are underutilized, evidence-based, and frequently the right answer when offered.

Ethics, Legal, and Patient Safety in Coordinated Care

— HIPAA permits PHI exchange for treatment, payment, operations without specific authorization — supports care coordination.

— 42 CFR Part 2 restricts substance use disorder records — requires patient consent for disclosure (2024 final rule aligning more with HIPAA, but still stricter).

— Adolescent confidentiality: state-specific minor consent laws for STI, contraception, mental health, substance use; portal access by parents must respect adolescent privacy.

Informed consent across transitions: each major intervention requires its own consent; consent from the OR does not extend to a new procedure on the ward. For shared decisions in primary care, use decision aids for preference-sensitive choices (PSA screening, lung cancer screening, anticoagulation).

Confidentiality:

Mandatory reporting: child abuse, elder/dependent adult abuse, certain communicable diseases, gunshot wounds, impaired drivers (varies by state) — non-negotiable even when it disrupts therapeutic alliance.

Transition-of-care safety: the moment of handoff is the highest-risk moment. Use standardized handoff (I-PASS: Illness severity, Patient summary, Action list, Situation awareness/contingencies, Synthesis by receiver). Verbal + written + read-back.

Information blocking (Cures Act): clinicians and EHRs must not unreasonably block patient access to their data; exceptions narrow.

Equity and language access: under Title VI and Section 1557 of the ACA, federally funded entities must provide qualified interpreters at no cost; using a minor child as interpreter is prohibited except true emergencies.

Disclosure of error: AHRQ/CANDOR framework — disclose promptly, apologize, explain, prevent recurrence; many states have apology laws protecting expressions of empathy.

Step 3 management: A hospitalized adult with no surrogate and lacking capacity needs life-sustaining decisions — the next step is state-specific surrogate hierarchy or court-appointed guardian / ethics consult, not assuming "do everything." Document capacity assessment.

Board pearl: A discharged patient whose pending culture grows resistant organism after discharge — the responsible clinician (often the discharging hospitalist) must promptly notify the patient and PCP; failure is both a patient-safety and medico-legal issue.

Just Culture distinguishes human error, at-risk behavior, reckless behavior.

I-PASS = standardized handoff.

Closed-loop referral = sent + seen + reported + acknowledged.

Step 3 management: When unsure, the answer often integrates: medication reconciliation + team-based follow-up within 7 days + addressing social barrier.

Board pearl: PCMH improves patient experience and quality consistently; cost reductions are modest and population-dependent — don't pick "guaranteed cost savings" answers.

Board Question Stem Patterns

— Best next step: medication reconciliation + nurse phone call within 72 h + clinic visit within 7 days (TCM bundle).

— Best next step: PCP-led care plan with care manager, not another specialist referral.

— Best next step: collaborative care model within primary care.

— Best next step: deprescribe benzo (Beers); multifactorial fall assessment.

— Best next step: system-level result tracking with acknowledgment; FMEA for prevention.

— Best next step: structured transfer using Got Transition six elements.

— Best next step: professional medical interpreter (in person, phone, or video).

— Best next step: generally release per Cures Act unless narrow harm exception applies.

— Best next step: comprehensive postpartum visit now with depression management and 2-h 75-g OGTT at 4–12 weeks.

— Best next step: empanel to PCMH, controller initiation, asthma action plan, care manager.

— Best next step: caregiver support + respite + community resources, screen with Zarit.

Pattern 1 — Post-discharge readmission risk: elderly patient discharged on multiple new meds, no scheduled follow-up.

Pattern 2 — Fragmented specialty care: diabetic with multiple specialists, no coordinated plan, worsening A1c.

Pattern 3 — Depression + chronic disease: PHQ-9 of 14 in a diabetic with A1c 9.

Pattern 4 — Polypharmacy fall: elderly patient falls on a benzodiazepine.

Pattern 5 — Closed-loop failure: incidental pulmonary nodule on chest CT never followed up.

Pattern 6 — Pediatric→adult transition: 19-year-old with sickle cell missing adult appointments.

Pattern 7 — Language barrier: LEP patient using teen daughter as interpreter.

Pattern 8 — Information blocking: clinician wants to withhold imaging results pending review.

Pattern 9 — Postpartum coordination: woman with gestational diabetes and EPDS of 13 not yet seen postpartum at 4 weeks.

Pattern 10 — Frequent ED utilizer for asthma: poor inhaler technique, no controller, no PCP.

Pattern 11 — Caregiver burnout: spouse caring for dementia patient now depressed.

Step 3 management: When two answers look right, choose the one that closes the loop (confirms receipt, schedules follow-up, documents acknowledgment) — incomplete actions are typically wrong.

Board pearl: "Refer to specialist" is rarely the single best answer in a coordination stem — better answers combine referral with a coordination action (warm handoff, shared care plan, follow-up scheduling).

One-Line Recap

High-yield recap bullets:

Care coordination through a Patient-Centered Medical Home delivers comprehensive, team-based, accessible, measured primary care that owns longitudinal accountability across transitions — and on Step 3, the right answer is almost always the option that empanels the patient to a primary care team, reconciles medications, closes the loop on referrals and results, and schedules timely structured follow-up with social-and-behavioral support woven in.

Five PCMH functions: comprehensive, patient-centered, coordinated, accessible, quality & safety — operationalized via empanelment, registries, pre-visit planning, team-based care, and measurement.

Transitions are the highest-risk moment: combat with medication reconciliation, teach-back, 48–72 h phone call, 7–14 day visit (TCM 99495/99496), and direct hospitalist-to-PCP communication.

Behavioral health integration through the Collaborative Care Model (PCP + BH care manager + psychiatric consultant + registry + stepped care) is the most evidence-based answer for depression in primary care and is billable via 99492–99494.

Special-population coordination: Beers/STOPP and deprescribing for elderly; Got Transition six elements for pediatric→adult; 3-week and 12-week postpartum visits with depression screening; professional interpreters for LEP; ACP at every transition.

Quintuple Aim anchors modern PCMH: better care, better health, lower cost, clinician well-being, and health equity — frame the "best" answer through these lenses when alternatives appear clinically equivalent.

CCS pearl: Always order medication reconciliation, schedule follow-up at a specific interval, close the loop on pending results, and address social determinants — these are the quiet point-earners in every coordination-flavored case.
