I am an Infectious Disease physician and I agree with over use of Sepsis
and CAP. I believe Sepsis term as such needs to be redefined. What I have
seen is even though physician don't want use term "sepsis" hospital and
case management tend to force admitting physician use sepsis if they have 2
of 4 SIRS criteria and possible source of infection. As rightly mentioned
before any patient presenting with fever will have tachycardia, and may
have slightly elevated WBC count, and that puts them in SIRS category and
of course if you are suspecting infection, case management will push for
writing sepsis as that increases DRG and reimbursement for Hospitals.

Pneumonia is again a "waste basket" diagnosis any one presenting with
respiratory symptoms and if have pulmonary infiltrates gets a diagnosis of
CAP by ED which is rarely revoked by admitting physician. I am usually
consulted when they are about discharge and admitting physician is not sure
if patient needs antibiotics upon discharge. Similarly any hospitalized
patient who is on Vent get a diagnosis of VAP if they have pulmonary
infiltrates on CXR, doesn't matter what is etiology of these infiltrates.
