Background:
Hospital-acquired pneumonia is now the number one hospital-acquired infection. Hospitals have addressed ventilator-associated pneumonia; however, patients not on a ventilator acquire more pneumonia with significant associated mortality rates.
Local Problem:
In our hospital, non-ventilator-associated pneumonia was occurring on all types of units.
Methods:
The Influencer Model was used to reduce nonventilator hospital-acquired pneumonia rates. Statistical process control R and X-bar-charts were monitored monthly.
Interventions:
After a gap analysis, an interdisciplinary team implemented enhanced oral care before surgery and on the units, changed tube management, and monitored stress ulcer medication.
Results:
We achieved a statistically significantly reduction (P = .01) in pneumonia rates that have been sustained over 4 years.
Conclusions:
Sustaining change requires (a) a continued team-based, collaborative approach, (b) ongoing stakeholder and executive leadership engagement, (c) monitoring that easy-to-use protocols and required equipment remain in place, and (d) embedded analytics to monitor results over a prolonged period.
