Rated A+
Medical intervention factors that affect risk of infection
indwelling devices, staffing ratio, lengths of stay, duration of
invasive procedures, medications, # of exams by providers, type of
institution, and knowledge/experience of providers
environmental intervention factors that affect risk of infection
disinfectant type used, contact with animals, hand hygiene
anatomical/phys factors that affect risk of infection
preexisting diseases, trauma, malignancies, age, gender, and
nutritional status
DMAIC
D=define customers, project boundaries, and processes
M=measure performance
A=analyze data to identify causes of variation, gaps in
performance, and prioritize actions
I=improve the process
C=control the process to prevent reverting
What should an effective surveillance program be able to provide?
Detection of infections and injuries, identify trends, identify risk
factors associated with infections and other AEs detect outbreaks
and clusters, assess the overall effectiveness of the infection
control and prevention program and demonstrate changes in
proactive and processes that lead to better outcomes
Define point prevalence
, number of persons ill on the date divided by the population on that
date.
Define attack rate
Number of people at risk in whom a certain illness develops /
(divided by) / Total number of people at risk
Define prevalence
fraction of a population having a specific disease at a given time
Define incidence
number of new cases of a disease divided by the number of
persons at risk for the disease.
Type of specimen for C. diff
liquid stool is required
When to suspect C. diff infection?
when 3 or more unformed/watery stool in 24 hrs occurs
Relative Risk (RR)
Used in cohort studies to determine how strongly a risk factor is
associated with an outcome.
1 is the null= no significance of the association between exposure
and adverse event
P(X infection or exposed)/P(Y infection or unexposed) = RR
Details of control chart
central line = the ave of data pts
x axis = time
y axis = rate/count
may be upper control/lower control limit lines and +/- 3 SD lines
Directly observed therapy (DOT)
requires that a health care provider directly observe the patient
swallowing the pills, whether it is in the hospital, office, or home
care setting
the best method for TB regimen, intermittent therapy, MDRO, high
risk for noncompliance (drug abusers/homeless)
Hill's Criteria of Causality
