Hospital-acquired infection prevention is a natural capstone topic because so much of the prevention work is done by nurses.
Hand hygiene, catheter care, line maintenance and ventilator care sit largely within nursing practice. Outcomes are defined nationally through CDC surveillance, and the evidence base includes guidelines, systematic reviews and trials. Payment policy adds a financial reason to care, since Medicare stopped paying the extra cost of certain hospital-acquired conditions in 2008.
How to Scope an Infection Project
Pick one infection (CAUTI is the most common BSN choice) and one unit. Anchor your intervention to a recognized prevention bundle, write a PICOT with a CDC NHSN rate such as CAUTIs per 1,000 catheter days, and add a process measure such as daily necessity review compliance.
For a proposal, published national data establishes significance; you do not need patient-level data from your site.
Choosing Your Hospital-Acquired Infection Focus
One infection and one setting keep the intervention specific. Addressing every hospital-acquired infection in one BSN project dilutes the plan.
| Infection | Full name | Main nursing interventions | Best setting |
|---|---|---|---|
| CAUTI | Catheter-associated urinary tract infection | Necessity assessment, aseptic insertion, closed drainage, nurse-driven removal protocol | Medical-surgical, ICU, long-term acute care |
| CLABSI | Central line-associated bloodstream infection | Maintenance bundle, dressing and cap changes, hand hygiene, daily necessity review | ICU, oncology, any unit with central lines |
| VAP | Ventilator-associated pneumonia | Head-of-bed elevation, oral care, sedation interruption, spontaneous breathing trials | ICU |
| HAP | Hospital-acquired pneumonia in non-ventilated patients | Oral care, mobility, aspiration precautions | Medical-surgical |
| C. diff | Clostridioides difficile infection | Contact precautions, soap and water hand hygiene, environmental cleaning, stewardship support | Any inpatient unit |
CAUTI or CLABSI for a BSN Project?
CAUTI is usually easier to scope. Nurse-driven catheter removal protocols sit firmly within nursing practice once approved. CLABSI prevention includes insertion, often done by physicians or advanced practitioners, so a BSN project should focus on maintenance rather than insertion.
A Model PICOT
PICOT: In adults with indwelling urinary catheters on a 28-bed medical-surgical unit, does a nurse-driven catheter removal protocol (daily necessity assessment with a standard criteria checklist) reduce the CAUTI rate per 1,000 catheter days compared with removal by provider order only over a 90-day pilot?
Why it works: a defined population and unit, a nurse-led intervention with a named tool, a comparison that reflects current practice, a standard NHSN outcome and a realistic time frame.
Because CAUTIs are relatively rare events on one unit, add catheter days or catheter utilization as a secondary outcome. It changes faster and shows whether the protocol is working even before infection numbers move.
If You Choose C. Diff or Hand Hygiene
C. diff projects need a different emphasis. Alcohol-based hand rub does not reliably remove C. diff spores, so guidance favors soap and water hand washing and gloves when caring for patients with known or suspected infection, along with sporicidal cleaning.
Hand hygiene projects often use the WHO "five moments" as their framework. Measure compliance by direct observation, but note the Hawthorne effect: staff wash more when they know they are watched, so rates can look better than everyday practice.
- C. diff outcome: hospital-onset C. diff cases per 10,000 patient days, using NHSN definitions.
- Hand hygiene outcome: observed compliance by moment, role and shift.
Anchor the Plan to a Prevention Bundle
A bundle shows your intervention comes from national guidance rather than invention. Name it, cite the source and describe how each element will be delivered and checked.
| Bundle | Typical elements |
|---|---|
| CAUTI (CDC and IHI guidance) | Insert only when indicated; aseptic insertion; closed drainage below bladder level; daily necessity review; prompt removal, including nurse-driven protocols |
| CLABSI insertion | Hand hygiene, maximal barrier precautions, chlorhexidine skin antisepsis, site selection avoiding the femoral vein in adults where possible |
| CLABSI maintenance | Daily necessity review, dressing changes on schedule, scrubbing the hub before access, chlorhexidine bathing where policy supports it |
| Ventilator care | Head of bed 30 to 45 degrees, daily sedation interruption, daily assessment for extubation, oral care, with other elements per local protocol |
Ventilator bundle content has shifted over time, for example around oral chlorhexidine. Cite the current guidance your site follows and check it before you finalize the plan.
CDC NHSN Metrics to Use
The National Healthcare Safety Network is the CDC's surveillance system for healthcare-associated infections. Using its definitions shows current knowledge and makes your outcomes comparable.
- CAUTI rate: CAUTIs per 1,000 urinary catheter days.
- CLABSI rate: CLABSIs per 1,000 central line days.
- Device utilization ratio: device days divided by patient days, a useful process indicator.
- SIR (standardized infection ratio): observed infections divided by predicted infections; below 1.0 means fewer infections than predicted.
- Ventilator-associated events: NHSN surveillance for ventilated adults uses VAE definitions, so mention this if your project is about VAP.
Implementation Essentials
Infection projects succeed or fail on consistent daily practice. Your plan should explain how the bundle becomes routine on every shift.
- Approval: nurse-driven removal protocols need approval from medical staff and the infection prevention committee.
- Education: short sessions on the criteria, return demonstration of insertion or dressing technique.
- Prompts: an EHR reminder for daily necessity review.
- Audits: weekly bundle compliance checks by champions or infection prevention staff.
- Feedback: a visible unit chart of days since the last infection and compliance rates.
Balancing measure example: for a catheter removal protocol, track urinary retention requiring reinsertion. It shows you considered unintended harm, which faculty look for in strong evaluation plans.
Outcome, Process and Balancing Measures
A strong evaluation plan uses three kinds of measure. Infection rates alone are slow to move on a single unit, so process measures carry much of the weight in a short project.
| Measure type | CAUTI example | CLABSI example |
|---|---|---|
| Outcome | CAUTIs per 1,000 catheter days | CLABSIs per 1,000 line days |
| Process | Daily necessity review documented; catheter days; utilization ratio | Maintenance bundle compliance; dressing intact and dated |
| Balancing | Reinsertions for urinary retention | Extra nursing time per line; skin reactions to chlorhexidine |
Collect a baseline before the change, then compare it with the same measures during and after the pilot. A run chart shows the trend more honestly than a single before and after number.
Frameworks That Fit Infection Projects
Most programs expect an EBP or change model to guide the project. Choose one you can apply step by step, not just name.
- Iowa Model: a clinical trigger (rising CAUTI rates) leads to a team, evidence review, pilot and decision to adopt.
- Johns Hopkins EBP model: practice question, evidence and translation, with its own appraisal tools.
- PDSA cycles: test the removal protocol on one shift, study the audit results, then refine and spread.
- Lewin's change theory: useful alongside an EBP model to explain how staff habits around catheter use will shift.
PDSA example: Cycle 1 tests the daily necessity checklist on day shift for two weeks. Audits show nights rarely complete it, so cycle 2 moves the prompt into the 06:00 assessment and adds a night champion. Cycle 3 extends the protocol to the whole unit once completion is consistent.
Writing the Significance Section
Current national figures from CDC, AHRQ or peer-reviewed studies are the right sources. Use them for incidence, mortality and cost, and cite the year. Avoid repeating older headline numbers that circulate online without a source.
Link the national picture to your unit: catheter use, line days or compliance gaps that make the problem matter locally. A sentence on Medicare's hospital-acquired condition payment policy adds the organizational perspective.
The Data You Need
For a proposal, you do not need infection data from your site. Published national rates establish significance, and you describe how the evaluation would collect data.
If your course includes a pilot, de-identified unit-level rates may be available from the infection prevention department. Confirm with your faculty and site whether a QI determination or IRB review is required before collecting any data.

Frequently Asked Questions
CAUTI is usually the easiest to scope because nurse-driven removal protocols are within nursing practice once approved.
Not for a proposal. Use published national data for significance and describe how your evaluation would collect data.
The NHSN CAUTI rate per 1,000 catheter days, plus catheter days or utilization as a faster-moving secondary measure.
The standardized infection ratio compares observed infections with the number predicted from national data. A value below 1.0 is better than predicted.
It is not advisable. One infection and one unit keep the intervention and evaluation specific.
Report device days, utilization and bundle compliance alongside the infection rate. These change faster and show whether the protocol is being followed even when infections are few.
Briefly. Medicare's non-payment for certain hospital-acquired conditions supports the organizational case for prevention.
