ventilator associated pneumonia
Ventilator Associated Pneumonia

VAP is defined as:

  • Acute inflammation of lung parenchyma caused by an infectious agent
  • A subset of Hospital Acquired Pneumonia (HAP)
  • Occurs > 48 hours after intubation

(Urden, et. al, 2006)

the practice problem
The Practice Problem
  • Patients intubated >24 hours are 6-21 times more likely to develop VAP than those intubated less than <24 hours
  • Incidence rate: 20-65%
  • VAP increases:
    • ventilator days by 4
    • critical care days by 4
    • hospital lengths of stay by 9 days
  • VAP mortality rates are 20-41%
  • The Bottom Line: Can increase costs by $50,000

(AACN, 2008)

previous practice
Previous Practice
  • Nursing staff failed to routinely integrate oral care and suctioning for patients on mechanical ventilation.
  • Failure to perform frequent and consistent oral care and suctioning had resulted in an increased incidence of VAP.

PICO

In ventilator dependant patients does oral care and suctioning using high-low, closed-suction and oral suction lower the incidence of ventilator associated pneumonia?

innovation intervention
Innovation/Intervention

For patients on a mechanical ventilator:

Initial Ventilator Orders @ ECRMC

  • Keep HOB elevated at 30-45 degrees if hemodynamically stable
  • Oral Care every 4hrs per policy
  • ET aspirate post-intubation (before antibiotics) & again in 3 days post intubation
  • Non-Diabetic pts- daily AM blood sugar, notify MD if glucose >120
  • Diabetic pts- capillary blood glucose Q6hrs, sliding scale
  • Hold sedation daily each morning with neurological assessment
literature review
Literature Review
  • Colonization of the oropharynx is a critical factor in developing nosocomial pneumonia (Muncro & Grap (2004)
  • Dental plaques provide a habitat for micro-organisms that can travel to the lungs & colonize (Fourrier, et. Al, 1998)
  • Dental plaque can be removed by brushing (ADA, 2006)
  • The ADA recommends brushing twice daily to remove plaque from all tooth surfaces (ADA, 2006)
  • The use of an oral care protocol reduces oral inflammation & improves oral health (Fitch, et. Al (1999)
objectives
Objectives

Decrease VAP by the following methods:

  • Educate RN’s on the significance of VAP & oral care protocol using the AACN Practice Alert (2008)
  • Improve performance & documentation of oral care frequency including oral care (brushing) and oral cavity moisturizing
implementation
Implementation
  • Protocol developed by VAP team consisting of RTs and RNs from all nursing departments
  • Protocol developed after reviewing research from VHA & IHI
  • Provision of supplies in ICU for oral care and ETT with Hi-Low suction
  • Nursing education in the ICU
  • Include the oral care procedure as part of unit orientation to ensure consistency of care
  • Documentation verification
  • Watching VAP trends in the ICU
results
Results
  • August 2007: oral care and moisturizing, use of ETT with Hi-Low suction, oral suctioning and in-line suction, HOB elevation, protocol initialed
  • Decrease in VAP cases @ ECRMC

2006: 8 VAP cases

2007: 5 VAP cases

2008: 3 VAP cases

2009: 0 VAP cases

swot analysis
SWOT Analysis
  • Strengths
  • Simplicity of the intervention
  • Lack of reimbursement
  • Cost effective
  • Weakness
  • Limited clinical studies
  • ER failure to obtain 1st sputum sample
  • Opportunities
  • High mortality
  • Cuts LOS
  • Cuts cost
  • Threats
  • Requires diligence
  • Prolonged ventilation
  • Additional risk factors
future implications
Future Implications
  • There is need for a large, well-controlled clinical trail of oral care interventions in critical care patients separate from the chlorhexidine studies
  • Ensure use of an ETT with a dorsal lumen above the endotracheal cuff to allow drainage by continuous suctioning of tracheal secretions that accumulate in the subglottic area (Tablan, et. al., 2004)
  • Patients requiring intubation > 7 days would benefit from an early tracheostomy. Evidence shows VAP incidence is 42.3% on late tracheostomies versus 27.2% on early tracheostomies (p<0.05) (Tablan, et. al., 2004)
  • Incorporate higher vigilance with patients who have other risk factors for VAP
future implications14
Future Implications
  • ECRMC is currently looking at trends/ problem areas
  • Pts intubated by EMS. EMS is currently not using ETT with Hi-Low suction
  • Pts transferred from Mexicali Vent days > 48hrs
  • Reviewing Weaning protocol
vap additional risk factors
VAP: Additional Risk Factors
  • Decreased level of consciousness
  • Supine positioning with HOB flat
  • Use of H2 antagonists and antacids
  • Gastric distention
  • Presence of gastric or small intestine tubes
  • Enteral feedings
  • Trauma
  • COPD

(AACN, 2008)

analysis of best practices
ANALYSIS OF BEST PRACTICES

According to AACN (2008), the best nursing practices in preventing VAP effectively are a combination of:

  • Good hand washing techniques
  • HOB elevation (30-45 degrees)
  • Brushing of teeth, gums & tongue at least twice daily
  • Oral moisturizers q 2-4 hours
  • Nasal, oral, and subglottal suctioning (high-low & deep suctioning included)
  • The use of chlorhexidine oral rinse for perioperative cardiac surgical patients
  • Daily sedation vacation
