Hospital readmission within 30 days is simultaneously a quality metric, a financial penalty trigger, and a signal that the care transition from hospital to home broke down. For nursing capstone students, readmission reduction is one of the most compelling topics available: it is tied directly to CMS payment policy, it is nurse-sensitive (discharge education, care coordination, post-discharge follow-up are all nursing roles), and the interventions are well-defined, evidence-based, and testable within a semester timeline.
The CMS policy context — why this matters
The Hospital Readmissions Reduction Program (HRRP), established by the Affordable Care Act and administered by the Centers for Medicare and Medicaid Services (CMS), reduces Medicare payments to hospitals with excess 30-day readmission rates for six conditions:
HRRP-tracked conditions (all 30-day all-cause readmission)
- Heart failure (HF)
- Acute myocardial infarction (AMI)
- Pneumonia
- Chronic obstructive pulmonary disease (COPD)
- Total hip and knee arthroplasty (THA/TKA)
- Coronary artery bypass graft (CABG)
Hospitals with excess readmission ratios above 1.0 face a payment reduction of up to 3% on all Medicare Part A payments. This financial incentive drives hospital investment in readmission prevention programs — making your capstone directly relevant to administrator priorities.
Beyond the HRRP conditions, high-risk readmission populations for nursing capstones include: patients with multiple chronic conditions, adults aged ≥75, patients discharged to home without home health, patients from low-income or under-resourced communities, and patients with limited health literacy or social support.
Evidence-based readmission prevention programs
| Program | Components | Best capstone angle |

Theoretical frameworks for readmission reduction capstones
| Framework | Best suited for | Application |
|---|---|---|
| Transitional Care Model (Naylor) | MSN capstones; APN-led transitions; high-complexity older adult populations | The TCM is both a theoretical framework AND an evidence-based program. If your capstone implements TCM elements, the framework and the intervention are aligned by design — a strength that simplifies your theoretical rationale chapter. |
| Care Transitions Framework (Coleman) | BSN capstones; patient activation-focused projects; the four-pillar approach | Readmission happens when patients are passive recipients of care transitions, not activated participants. Coleman's framework positions patient activation — particularly around medication management and self-advocacy — as the mechanism through which readmission is prevented. |
| Chronic Care Model (Wagner) | Chronic disease-specific readmission prevention (HF, COPD, diabetes, CKD) | Readmission in chronic disease reflects a system failure at the intersection of self-management support, delivery system design, and clinical information systems. Your intervention addresses one or more of these three levers simultaneously. |
| Health Belief Model (HBM) | Patient education components; teach-back programs; medication adherence education | Patients who understand their susceptibility (I could be readmitted), severity (readmission is dangerous and costly), and the benefits of specific self-management behaviors (daily weighing prevents HF decompensation) are more likely to follow discharge instructions. Your education intervention builds perceived susceptibility and reduces perceived barriers. |
The 30-day readmission timeline problem — read before choosing your outcome
30-day readmission is the standard primary outcome in the literature and policy context, but it is also the most difficult outcome to measure in a capstone. Here is why, and how to handle it:
- The timeline math: If your implementation phase is 8 weeks and you enroll patients over those 8 weeks, your last-enrolled patient's 30-day window closes 30 days after discharge — potentially 4–6 weeks after your implementation phase ends. If your total program timeline does not accommodate this, you cannot report 30-day readmission as a completed primary outcome.
- Solutions: (1) Use a proximal nursing-sensitive primary outcome — phone call completion rate, discharge education documentation rate, or teach-back pass rate — and designate 30-day readmission as a secondary outcome requiring longer follow-up. (2) Frame the project as an EBP proposal with a detailed evaluation plan including readmission as the primary outcome. (3) Conduct a retrospective chart review on existing data from a prior implementation if your site has historical data.
- Avoid this error: Do not claim you measured 30-day readmission if your data collection ended before the follow-up window closed. Committees will catch this and it is a major methodological flaw.

Frequently asked questions
The LACE index is a validated readmission risk score derived from four variables routinely available in hospital administrative data: Length of stay (0–7 points), Acuity of the admission (1 point if emergent), Comorbidity burden (Charlson Comorbidity Index, 0–5 points), and number of Emergency department visits in the 6 months before admission (0–4 points). Total scores range from 0–19; scores ≥10 identify patients at high risk for 30-day readmission or death. In your capstone, LACE is used at the eligibility screening step — you enroll only patients with LACE ≥10 (or whatever threshold your site uses) because you want to target your intervention toward patients who are most likely to benefit. This narrows your population, strengthens the clinical rationale for your intervention, and makes your capstone more methodologically defensible. LACE can be calculated from EHR discharge data and does not require patient interaction.
All four are evidence-based care transition programs with demonstrated readmission reduction in randomized controlled trials, but they differ in who delivers the intervention, what components are included, and how intensive the follow-up is. BOOST is hospital-based, nurse-driven, and focuses on risk screening plus structured discharge preparation and a 72-hour phone call — practical for unit-level BSN QI capstones. TCM (Transitional Care Model) is APN-led, includes home visits, and is designed for complex older adults with multiple chronic conditions — appropriate for MSN capstones or nurse practitioner focus. CTI (Care Transitions Intervention) is coach-led (not necessarily APN), uses four "pillars" of patient activation, includes one home visit and three phone calls — moderate intensity, can be adapted for BSN or MSN. RED (Re-Engineered Discharge) is hospital-based, uses a dedicated nurse discharge educator, and is focused entirely on the inpatient discharge preparation process — no post-discharge follow-up visits are part of the core model, though the 2–4 day phone call is included. Choose the program whose intensity and role requirements match your site access and program level.
Yes — while heart failure, COPD, AMI, pneumonia, THA/TKA, and CABG are the CMS-penalized conditions with the highest evidence base, readmission prevention interventions are applicable to any high-risk population. Strong non-HRRP readmission capstone populations include: sepsis survivors, patients with end-stage renal disease (ESRD) on hemodialysis, adults with sickle cell disease (frequent readmitters with complex needs), psychiatric patients with co-occurring chronic medical conditions, and cancer patients on active chemotherapy. The evidence base for readmission prevention in these populations is less mature — which can be a strength (your capstone adds to a gap in the literature) or a weakness (less existing protocol guidance). Confirm your site's readmission data for the population you choose to justify clinical significance.
