The alphabet soup of pneumonia: CAP, HAP, HCAP, NHAP, and VAP.
Anand N, Kollef MH.
2009
HCAP
Pneumonia occurring ≤ 48 hours of hospital admission in patients
with ≥ 1 of the following risk factors for MDR bacteria as cause of
infection: —Hospitalization for ≥ 2 days in an acute-care facility
within 90 days of infection —Residence in a nursing home or
long-term care facility —Antibiotic therapy, chemotherapy, or wound
care within 30 days of current infection —Hemodialysis treatment at
a hospital or clinic —Home infusion therapy or home wound care
—Family member with infection due to MDR bacteria
HAP
Pneumonia occurring ≥ 48 hours after hospital admission • Risk
factors for MDR bacteria causing HAP —Antibiotic therapy within 90
days of infection —Current hospitalization of ≥ 5 days —High
frequency of antibiotic resistance in community or specific
hospital unit —Immunosuppressive disease or therapy —Presence of
HCAP risk factors for MDR
VAP Pneumonia occurring > 48 hours after endotracheal intubation
• Risk factors for MDR bacteria causing VAP —Presence of HCAP or
HAP risk factors for MDR

1. Le choix initial de l’antibiothérapie au cours des PAVM reste un
exercice
difficile qui doit tenir compte d’un ensemble de paramètres liés ou
non au patient.
2. Comme pour toutes les infections, la ré-évaluation à J2-J3 est
indispensable.
3. L’administration des antibiotiques doit tenir compte de leur

4. Une durée de traitement courte est possible.

Major Points and Recommendations for Modifiable Risk Factors
General prophylaxis.
1. Effective infection control measures: staff education,
compliance with alcohol-based hand disinfection, and isolation to
reduce cross-infection with MDR pathogens should be used routinely
(Level I). 2. Surveillance of ICU infections, to identify and
quantify endemic and new MDR pathogens, and preparation of timely
data for infection control and to guide appropriate, antimicrobial
therapy in patients with
suspected HAP or other nosocomial infections, are recommended
(Level II).
Intubation and mechanical ventilation. 1. Intubation and
reintubation should be avoided, if possible, as it increases the
risk of VAP (Level I). 2. Noninvasive ventilation should be used
whenever possible in selected patients with respiratory failure
(Level I). 3. Orotracheal intubation and orogastric tubes are
preferred over nasotracheal intubation and nasogastric tubes to
prevent nosocomial sinusitis and to reduce the risk of VAP,
although direct causality has not been
proved (Level II). 4. Continuous aspiration of subglottic
secretions can reduce the risk of early-onset VAP, and should be
used, if available (Level I). 5. The endotracheal tube cuff
pressure should be maintained at greater than 20 cm H2O to prevent
leakage of bacterial pathogens around the cuff into the lower
respiratory tract (Level II). 6. Contaminated condensate should be
carefully emptied from ventilator circuits and condensate should be
prevented from entering either the endotracheal tube or in-line
medication nebulizers (Level II). 7. Passive humidifiers or
heat–moisture exchangers decrease ventilator circuit colonization,
but have not consistently reduced the incidence of VAP, and thus
they cannot be regarded as a pneumonia prevention tool
(Level I). 8. Reduced duration of intubation and mechanical
ventilation may prevent VAP and can be achieved by protocols to
improve the use of sedation and to accelerate weaning (Level II).
9. Maintaining adequate staffing levels in the ICU can reduce
length of stay, improve infection control practices, and reduce
duration of mechanical ventilation (Level II).
Aspiration, body position, and enteral feeding.
1. Patients should be kept in the semirecumbent position (30–45°)
rather than supine to prevent aspiration, especially when receiving
enteral feeding (Level I). 2. Enteral nutrition is preferred over
parenteral nutrition to reduce the risk of complications related to
central intravenous catheters and to prevent reflux villous atrophy
of the intestinal mucosa that may increase the
risk of bacterial translocation (Level I).
Modulation of colonization: oral antiseptics and antibiotics. 1.
Routine prophylaxis of HAP with oral antibiotics (selective
decontamination of the digestive tract or SDD), with or without
systemic antibiotics, reduces the incidence of ICU-acquired VAP,
has helped contain
outbreaks of MDR bacteria (Level I), but is not recommended for
routine use, especially in patients who may be colonized with MDR
pathogens (Level II). 2. Prior administration of systemic
antibiotics has reduced the risk of nosocomial pneumonia in some
patient groups, but if a history of prior administration is present
at the time of onset of infection, there should be
increased suspicion of infection with MDR pathogens (Level II). 3.
Prophylactic administration of systemic antibiotics for 24 hours at
the time of emergent intubation has been demonstrated to prevent
ICU-acquired HAP in patients with closed head injury in one study,
but its routine
use is not recommended until more data become available (Level I).
4. Modulation of oropharyngeal colonization by the use of oral
chlorhexidine has prevented ICU-acquired HAP in selected patient
populations such as those undergoing coronary bypass grafting, but
its routine use is
not recommended until more data become available (Level I). 5. Use
daily interruption or lightening of sedation to avoid constant
heavy sedation and try to avoid paralytic agents, both of which can
depress cough and thereby increase the risk of HAP (Level
II).
Stress bleeding prophylaxis, transfusion, and hyperglycemia.
1. Comparative data from randomized trials suggest a trend toward
reduced VAP with sucralfate, but there is a slightly higher rate of
clinically significant gastric bleeding, compared with H2
antagonists. If needed, stress bleeding prophylaxis with either H2
antagonists or sucralfate is acceptable (Level I).
2. Transfusion of red blood cell and other allogeneic blood
products should follow a restricted transfusion trigger policy;
leukocyte-depleted red blood cell transfusions can help to reduce
HAP in selected patient populations (Level I).
3. Intensive insulin therapy is recommended to maintain serum
glucose levels between 80 and 110 mg/dl in ICU patients to reduce
nosocomial blood stream infections, duration of mechanical
ventilation, ICU stay, morbidity, and mortality (Level I).

C’est une méthode structurée pour améliorer le processus de
soin
(et donc le pronostic des patients).
Il est composé d’un petit ensemble simple et cohérent de plusieurs
pratiques,
généralement 3 à 5, bien définies, fondées sur des preuves
scientifiques solides
et qui mis en œuvre correctement (95% d’adhérence), se traduit par
un meilleur
résultat sur le pronostic que lorsque chaque mesure est utilisée
seule.

Rello, ICM, 2010 Criterion Mean weighting score Ease of
implementation within a care bundle package How easy it will be to
implement the element of the care bundle? 18
Clinical effectiveness against VAP and the likely benefit Is there
evidence that the intervention is clinically effective in its
impact upon VAP? How big a benefit does the intervention
produce?
16
Strength of clinical evidence concerning the intervention How good
is the evidence that demonstrates the benefit of the intervention?
Is all the evidence of the same standard? Are the study results
relevant across the range of health systems?
15
Consistency of findings from different studies Are the findings of
these studies consistent? Do the studies demonstrating benefit come
from a range of health systems?
9
Generalisability to different health care systems and settings Is
the recommendation acceptable across different health care systems?
9
Volume of clinical evidence supporting the intervention How many
studies are available to show that benefit exists from the
recommendation? Do the studies demonstrating benefit come from a
range of health systems?
8
Cost effectiveness of the intervention Is the intervention cost
effective? How cost effective is the intervention across the
different health care systems?
7
Coverage in all VAP patients Is the benefit uniform across the
complete VAP group of patients? 5
Impact on the health care system as a whole Think about the impact
(positive or negative) on other services, e.g. will this
intervention increase/decrease work load for other services (can
this other part of the service deliver?), e.g.
laboratories/imaging

Ils ont plusieurs avantages:
Ø ils permettent de contourner les contraintes du "case mix”,
Ø l’objectif est clair = observance de 100% (95%),
Ø la surveillance est en général facile,
Ø ils sont plus fréquents que les infections si bien qu’il est
facile
de détecter rapidement une déviation par rapport aux bonnes
pratiques et de la corriger .
