9.1 Evidence-Based Care Transition Models and Discharge Execution

Evidence-Based Care Transition Models and Discharge Execution

The transition from an acute care hospital to home or a post-acute facility represents the most clinically vulnerable juncture in a patient's healthcare trajectory. A widely cited study of discharged medical patients found that about 1 in 5 had an adverse event after discharge, and roughly two-thirds of those events involved medications. For the Accredited Case Manager - Registered Nurse (ACM-RN), mastering structured, evidence-based care transition models is essential not only to safeguard patient safety and mitigate 30-day readmissions, but also to fulfill the core mandates of Domain II in health delivery system case management.

Evidence-Based Care Transition Frameworks

Over the past two decades, three primary evidence-based transition frameworks have achieved national validation and widespread adoption across American health systems: Project RED (Re-Engineered Discharge), the Care Transitions Intervention (CTI / Coleman Model), and Project BOOST (Better Outcomes for Older adults through Safe Transitions). Each model approaches care continuity from a distinct operational and clinical angle.

1. Project RED (Re-Engineered Discharge)

Developed by clinical researchers at Boston University Medical Center and funded by the Agency for Healthcare Research and Quality (AHRQ), Project RED is a standardized, hospital-based intervention designed to improve the discharge workflow, enhance patient self-management, and reduce preventable 30-day readmissions and emergency department visits. In its 2009 randomized trial, Project RED reduced combined emergency department visits and readmissions within 30 days by about 30%.

The AHRQ Project RED toolkit lists 12 components, carried out by a discharge educator, nurse, or case manager:

1. Ascertain need for and obtain language assistance.
2. Make appointments for follow-up care, including post-discharge tests, with attention to transportation.
3. Plan for follow-up of results that are pending at discharge, naming the clinician responsible.
4. Organize post-discharge outpatient services and medical equipment.
5. Identify the correct medicines and a plan for the patient to obtain them, including reconciliation against pre-admission medicines.
6. Reconcile the discharge plan with national guidelines (for example, guideline-directed therapy for heart failure).
7. Teach a written discharge plan the patient can understand: the illustrated, color-coded After Hospital Care Plan (AHCP) with appointments, a medication schedule, and warning signs.
8. Educate the patient about the diagnosis and medicines throughout the stay, not only on the day of discharge.
9. Review what to do if a problem arises, including whom to call.
10. Assess the patient's understanding of the plan using teach-back.
11. Expedite transmission of the discharge summary to the clinicians who will follow the patient.
12. Provide telephone reinforcement of the discharge plan: a nurse or pharmacist calls 2 to 3 days after discharge.

2. Care Transitions Intervention (CTI / Coleman Model)

Developed by Eric A. Coleman, MD, MPH, the Care Transitions Intervention (CTI) is a 30-day, patient-centered, cross-setting empowerment model. Unlike traditional case management models that emphasize provider coordination, the Coleman model is rooted in adult learning theory and self-efficacy theory: its foundational philosophy is to empower the patient and family caregiver to become active directors of their own care.

The intervention is facilitated by a Transition Coach (a registered nurse or medical social worker) and consists of one inpatient hospital visit, one in-home visit within 48 to 72 hours of discharge, and three follow-up telephone calls during the rest of the 30-day period. The intervention is structured entirely around Four Core Pillars:

• Pillar 1: Medication Self-Management: The patient masters a system for managing medications independently, maintains an active, updated medication list, understands the purpose of each drug, and can articulate potential side effects and warning signs.
• Pillar 2: Dynamic Personal Health Record (PHR): The patient actively manages and owns a portable, paper-based or digital Personal Health Record containing medical history, active diagnoses, red-flag symptoms, and questions for upcoming clinician appointments. The patient is coached to carry the PHR to every clinical encounter.
• Pillar 3: Timely Primary Care / Specialty Follow-Up: The patient understands the importance of attending post-acute appointments, is empowered to schedule their own follow-ups, and learns how to formulate and present key clinical questions directly to the physician.
• Pillar 4: Knowledge of Condition-Specific "Red Flags": The patient and family learn to recognize early symptoms indicating that their condition is worsening, understand the exact action steps required, and know whom to contact immediately before symptoms require emergency hospitalization.

3. Project BOOST (Better Outcomes for Older adults through Safe Transitions)

Initiated by the Society of Hospital Medicine (SHM), Project BOOST is a multidisciplinary, hospital-based quality improvement toolkit designed to optimize care transitions specifically for older adult populations. Project BOOST provides clinical tools to identify patients at high risk of adverse events and readmission upon presentation, deploying tailored transition bundles.

The cornerstone of Project BOOST is the 8Ps Risk Assessment Tool, which stratifies transition risk across eight distinct clinical and psychosocial domains:

Discharge Medication Reconciliation and Meds-to-Beds Programs

Medication discrepancies are the leading cause of post-discharge adverse drug events (ADEs). The Joint Commission requires a systematic medication reconciliation process at transitions of care (NPSG.03.06.01 through 2025; for hospitals, now part of the 2026 National Performance Goals).

The Five-Step Medication Reconciliation Process

1. Develop a comprehensive pre-admission medication list: Interview the patient/family, inspect home medication vials, and verify pharmacy fill records and electronic health information exchanges (HIEs) to capture prescription drugs, over-the-counter (OTC) products, vitamins, and herbal supplements.
2. Develop a list of newly ordered inpatient medications: Review active acute treatments administered during the hospital stay.
3. Compare pre-admission medications against inpatient orders: Systematically cross-reference both lists to identify intentional modifications versus unintentional omissions, duplications, dosing errors, or contraindications.
4. Make clinical decisions based on the comparison: Collaborate with the attending physician and clinical pharmacist to finalize the post-discharge regimen, ensuring stopped medications are explicitly documented as discontinued.
5. Communicate the finalized regimen: Provide the reconciled medication list to the patient, caregiver, community pharmacy, and next-level care providers (primary care, home health, or skilled nursing facility).

Resolving Financial and Authorization Barriers

A technically perfect discharge medication reconciliation is useless if the patient cannot afford or obtain the medications upon leaving the hospital. Case managers must proactively address:

• Prior Authorizations (PAs): Specialty drugs (e.g., direct-acting oral anticoagulants [DOACs], heart failure SGLT2 inhibitors, GLP-1 receptor agonists) frequently require payer prior authorization. Initiating PAs 24 to 48 hours prior to anticipated discharge prevents patients from arriving at retail pharmacies only to face claim rejections.
• High Out-of-Pocket Copayments: For commercial patients, case managers leverage manufacturer copay assistance cards. For Medicare beneficiaries (where copay cards are legally prohibited under the federal Anti-Kickback Statute), case managers connect patients to disease-specific charitable foundations (e.g., Patient Access Network Foundation, HealthWell Foundation).
• 340B Drug Pricing Programs: Eligible safety-net and disproportionate share hospitals can use 340B savings to offer low-cost medications to eligible low-income or uninsured patients through hospital pharmacies.

Bedside Medication Delivery ("Meds-to-Beds") Programs

Meds-to-Beds programs represent a proven operational model that eliminates post-discharge pharmacy fill barriers. Under this protocol, the hospital's outpatient pharmacy processes, fills, and delivers discharge prescriptions directly to the patient's bedside prior to physical discharge.

Key clinical advantages of Meds-to-Beds include:

• First-Fill Assurance: Verifies that the patient physically has essential medications before leaving the hospital.
• Bedside Pharmacist / Nurse Consultation: Allows face-to-face medication education, ensuring the patient demonstrates correct inhaler technique, insulin pen administration, or subcutaneous anticoagulant injection.
• Real-Time Adjudication: Financial rejections, high copayments, and prior authorization deficits are identified and resolved while the attending medical team is still accessible to adjust therapies if necessary.

Discharge Teach-Back Methodology

Traditional discharge education that relies on passive questions such as "Do you understand?" or "Do you have any questions?" often misses misunderstanding. Patients frequently nod out of embarrassment, deference, or cognitive overload.

The Teach-Back method (also known as the "show-me" method) is a structured, evidence-based communication technique where the clinician assesses patient comprehension by asking the patient or caregiver to state in their own words or demonstrate what they need to know or do.

The Closed-Loop Teach-Back Cycle:

│ Clinician Explains 1-2 Key Concepts ("Chunk")         │

└────────────────────────┘   └───────────────────────────┘

Key Principles of Effective Teach-Back

• Chunk and Check: Never overload the patient with the entire discharge packet at once. Deliver instructions in small, digestible "chunks" of 1 to 2 key points, and immediately "check" comprehension before moving forward.
• Shift the Burden to the Clinician: Frame the prompt so the patient does not feel tested or interrogated. Use phrasing such as: "I want to make sure I gave you clear instructions today. When your daughter asks you tonight how you are supposed to take this water pill, what will you tell her?"
• Action-Oriented Prompts: Focus teach-back on high-stakes execution: medication dosing/timing, red-flag symptoms, what specific phone number to call, and return precautions.
• Show-Me Demonstrations: For devices (glucometers, incentive spirometers, subcutaneous enoxaparin injections, wound dressings), require the patient or caregiver to physically manipulate and demonstrate proper technique.
• Closed-Loop Remediation: If the patient demonstrates incomplete or incorrect understanding, the case manager must re-teach the concept using alternative words or visual aids, and subsequently re-assess comprehension until closed-loop mastery is achieved.
