A CLABSI Cluster on the PICU and the NP as QI Lead
You are the lead acute care NP on a 24-bed PICU. The unit's central line–associated bloodstream infection rate over the last 12 months is 4.2 per 1,000 central line days, compared with a national benchmark near 1.0. A chart audit of 40 line days shows 62% documented compliance with scrub-the-hub technique, 40% documentation of daily CHG bathing, and only 30% of progress notes addressing whether the line is still necessary. Two of the four recent infections occurred in children with lines placed in the operating room and maintained for more than 3 weeks for total parenteral nutrition. Staff say the checklist 'doesn't apply' to short-term lines, and the culture on the unit is to avoid calling out senior colleagues.
1. How would you structure this as a quality improvement project rather than a policy memo?

Start with measurement and a driver diagram, not a rule.
- Define and validate the measure. Confirm the case definition and denominator with infection prevention (NHSN criteria). Verify the 4.2 rate is real and not a surveillance artifact - check whether the increase is in one organism, one unit section, or one line type.
- Stratify the data by line type, dwell time, insertion location, unit, and organism. The TPN lines placed in the OR are a distinct subgroup - a single bundle may not fit them.
- Run a root cause analysis on the most recent 3–4 cases: human factors, supply availability (are CHG wipes stocked at the bedside?), workflow (who bathes the child and when), and hierarchy (did anyone see a breach and stay silent?).
- Build a key-driver diagram with primary drivers: insertion practice, maintenance practice, device necessity, and safety culture. Then select interventions with the strongest evidence for each driver.
- Use PDSA cycles on a small scale - one team, one week, test a bedside 'line necessity' prompt at rounds. Measure, adapt, then spread. Do not launch a hospital-wide rollout first.
- Choose a balanced set of measures: outcome (CLABSI rate per 1,000 line days), process (scrub-the-hub compliance, CHG bathing documentation, daily necessity discussion), and balancing measures (line removal complications, staff burden, time to antibiotics for new fever).
2. What specific bundle changes would you prioritize, and how do you make them stick given the culture described?

Prioritize the highest-yield, lowest-friction changes:
- Maintenance bundle, not just insertion: scrub the hub for 15 seconds with friction and allow to dry; CHG-impregnated caps where appropriate; daily CHG bathing for children over 2 months (with careful skin assessment in neonates and preterms); dressing integrity checks each shift.
- Daily line necessity huddle - a one-line question at rounds for every patient with a line, documented in the note. This directly targets the 3-week TPN lines; involve the surgical and nutrition teams in the discussion of whether a PICC or enteral route is feasible.
- Make the right thing easy: stock CHG wipes and caps in every room, put the scrub-the-hub reminder on the IV pole, and pre-populate the EHR note template with the necessity field.
- Audit and feedback with names removed but units identified - weekly compliance data posted visibly. Feedback is one of the most reliable behavior-change levers.
- Address the culture directly: the 'don't call out seniors' norm is the real driver. Use a standardized phrase ('I need clarity - can we scrub the hub again?'), have a senior physician and nurse leader visibly model being corrected, and add a brief safety huddle where anyone can raise a concern without hierarchy. Consider team-based simulation of a line access breach.
- Engage families in hand hygiene and asking about the line - this both improves practice and shifts the culture.
Sustaining: embed the bundle in onboarding and annual competency, add it to daily safety huddles, share monthly data with the unit and with hospital leadership, and celebrate reductions publicly. Culture change follows visible leadership behavior and consistent data, not another memo.
3. The infections continue and hospital leadership asks whether to escalate. What is your recommendation, and what system-level advocacy is warranted?
Read the worked answer
Recommend escalation with a specific ask, not a general alarm.
- Present the data in leadership's language: attributable infections, excess bed days, excess cost per CLABSI (commonly cited in the tens of thousands of dollars), and harm to patients, alongside the trend since the PDSA work began.
- Ask for concrete resources: protected staff time for the QI team, a data analyst, CHG supply budget, and authority to make the daily line-necessity discussion a required element of rounds.
- Escalate through the right channels: the hospital quality and patient safety committee, infection prevention, and the medical executive committee. Report to the board quality committee if the trend does not improve - CLABSI is a publicly reported, pay-for-performance measure, and this creates leverage.
- Benchmark externally: participate in NHSN or a collaborative; comparison against peer PICUs is often more persuasive than an internal target.
- Protect the reporting culture: the most dangerous response to a rising rate is blame. If staff fear punishment, reporting will drop and the measured rate will fall without the harm falling. State this explicitly to leadership.
- Advocacy beyond the unit: if supply shortages or staffing ratios are contributing, document that and raise it as a systems issue, not an individual performance issue. The NP role is to name the system cause and propose the fix.
- Family voice: consider including a family advisor on the QI team - families are strong advocates for line safety and their perspective improves both the intervention and its credibility.
