Introduction
•
•
•
•
•
•
Reduction of antibiotic use
Initial assessment of antibiotic use
Provider and patient education
Incentives to reduce inappropriate use
Follow-up studies
Future reduction
Urgent Care History
• SMA Urgent Cares 100,000 visits a
year
• High volume of respiratory infections
• High rate of antibiotic prescriptions
Inappropriate Uses
• Over one-half of all antibiotics
written annually are for respiratory
infections
• More than 50 million unnecessary
prescriptions are written annually
• 17 million prescriptions for antibiotics
are written for the common cold
• Antibiotics are given to 75% of
patients with sore throat
Initial Study
• Random charts pulled for upper
respiratory complaints
• Symptoms of cough, sore throat,
runny nose, congestion, sinus pain
• Percentage of patients prescribed an
antibiotic
Results of Initial Study
•
•
•
•
•
Overall prescription rate 66.7%
Fulltime providers 53.5%
Per diem providers 78.8%
Range 14-100%
3 providers prescribed antibiotics
100% of the time!
Methods to Reduce
Inappropriate Use
• Patient education
– Handouts
– Posters
– Discussion
• Provider education
• Financial incentives to reduce
inappropriate use
Provider Education
• URIs are self-limiting
• Colored secretions are not predictors
of bacterial infection
• Bronchitis is viral in nature
• Differentiate sinus symptoms from
sinus infection
• Otitis media is oftentimes selflimiting
• Criteria for Strep throat
Financial Incentives
• SMA Bonus
• Antibiotic use as quality measure
• Goal set at less than 45%
Results
• After 3 months rate decreased to
34.2%
• After 6 months rate decreased to
30.5%
Patient Satisfaction
• Overall patient satisfaction rate
remains high
• Some disgruntled patients
• Less resistance from patients
Rocephin
• In 2001 Rancho Urgent Care used
$70,000
• Provider education and guidelines
• In 2002 all 3 SMA Urgent Cares used
$40,000

Stop Antibiotic
Resistance In Washoe
County!
How Can Childcare Providers
Help?
Joyce Minter, RN, PHN

About one-third of
Nevada’s children under
the age five are in some
form of licensed childcare
because their parents

Consulting; Trust Fund for Public Health, RFA
2002-2003
Approximately 10,000
children under age six
attend 327 licensed
childcare homes and
1
centers in Washoe County

Consulting; Trust Fund for Public Health, RFA
2002-2003
Childcare providers play a
key role in disseminating
information and health
education to children and
families
Antimicrobial Resistance (AR)
outreach was put into the Child
Care Health Consulting (CCHC)
grant, a Trust Fund for Public
Health (TFPH) grant, to do
education and evaluation of efforts
The CCHC is part of Health Child
Care Nevada, which is part of the
Health Care America campaign
Plan
• Send a survey to all (1250) child care
providers
• Educate staff at 3 centers and 9
homes
• Then do a follow-up survey on those
selected providers to see if they
learned anything
Childcare Consultants
Grant
• Printing and postage paid through
grant
• PHN time was “in kind” contribution
AR Objective of Grant
• Targeted child care providers will
achieve scores at least 10% higher
than the entire population of providers
in Washoe County on a survey
measuring knowledge of antibiotic
resistance after an educational session
is completed
Child Care Providers
• Obtained list of childcare providers
from Social Services-approx. 1250
questionnaires sent out
1---------232
5---------39
10--------34
20--------16
30--------5
Questionnaire
Development
• Made a list of 20 most important
messages we wanted to convey
• Put into questionnaire form and data
base created (special “Thanks” to Lei
Chen)
• Questionnaires coded with identifying
information so we could compare pretest with post test
Survey Packet
• Letter explaining program and instructions to
return questionnaire:
If a childcare center - to fax completed
questionnaires
If individual childcare provider envelope with return postage guaranteed
• Questionnaire
• Business card
• 2 NAA AR bookmarks for each provider as a
“Thank you”
Ideas for Incentives
•
•
•
•
•
•
Totes – NAA
Continuing education credit
Mugs
Water bottles
Purell hand sanitizer
Magnets-able to use some
immunization funding
• A drawing/raffle
Activities
• Mailed survey to all licensed child
care providers to assess baseline
knowledge of antibiotic resistance and
entered data for analysis
• Provided educational materials about
antibiotic resistance to targeted centers
• Provided survey to targeted centers
post intervention to measure change in
attitudes
Initial Questionnaire
Results
• 346 of 1250 returned = 28% response
rate
• Average score was 75.1, standard
deviation 13.8. Range of score was
25-100. Full score is 100.
Stop Antibiotic
Resistance In Washoe
County!

A special thanks to Jane Harper, MS, at Minnesota
Department of Health for providing most of the
information in this presentation
Learning Objectives
• List two types of germs that cause
common childhood respiratory
illnesses
• State what antibiotics cannot do if
you are sick with a viral infection
• List comfort measures that can help
children with viral infections feel
better (hint: an antibiotic is not one
of them!)
Learning Objectives
• Name one myth and one fact about
antibiotic use
• List 3 steps childcare providers can
take to help keep antibiotics working
• Name one bacterial illness which can
be prevented by proper immunization
• State the most effective way to prevent
the spread of all infections in childcare
Take Home Messages
• Viruses cause most common
childhood respiratory illnesses
• Viral illnesses need time to heal antibiotics cannot help
Take Home Messages
• Taking antibiotics for viral illnesses
will not:
– cure the infection
– keep others from getting the
illness
– make you feel better
And may lead to antibiotic-resistant
bacteria
Take Home Messages
• Comfort measures ease symptoms of
viral illnesses (extra fluids, rest, a
vaporizer, a smoke-free environment)
• Sick children should stay home until
fever-free and able to participate in
routine activities without more care than
usual from childcare staff
• Always wash your hands - and help
children wash theirs!
• Keep immunizations up to date
Bottom Line
• Antibiotics are powerful medicines,
but they're not always the answer!
• Misusing antibiotics now means
they may not work when needed
later to fight a bacterial infection
• Help keep antibiotics working!
Education & Post-Test
• The three centers have completed
the education and post-testing
• The nine individual providers will
be completed by May
Post-Test Survey Results
• 57 post-tests completed
• Average score: 89.5, standard deviation 12.9.
Range of score is 42-100. Full score 100.
(pre-test average: 75.1)
• Paired comparison result: Fifteen participated
in pre and post test. The average score was
improved by 13 before and after the education
(statistically significant---P=0.005 by pairing
sample T-test).
• 56/57 (98%) participants indicated on their
post-tests that the presentation was very useful

Measuring the Appropriate
Use of Antibiotics

HEDIS--Who, What & How
• Administered by NCQA
• Used by most HMO’s across the country to
measure plan performance
• Standardized methodology and comprehensive
audit checks to ensure comparability
• In Nevada, Aetna, Health Plan of Nevada, IHC
Health Plans, and Pacificare, already publicly
report results
• HMO Nevada does not currently publicly
report results due to size, although does collect
the data
New to HEDIS 2004
• Appropriate Treatment of Children
With Upper Respiratory Infection
– Children age 3 months to 18 years
– Outpatient visit with diagnosis of URI
(460 or 465) ONLY (no secondary
diagnosis
– % with no prescription for antibiotic 30
days before visit date or 3 days after
visit date
New to HEDIS 2004
• Appropriate Testing for Children With
Pharyngitis
– Children age 2 to 18 years
– Outpatient visit with diagnosis of
pharyngitis (462, 463, 034.0), ONLY
– Received a prescription for antibiotic 3
days before visit date to 3 days after visit
date
– % that also had a group A streptococcus
test
Considerations for NAA
• This may be a way to measure the
effectiveness of FUTURE
interventions
• Would allow for benchmarking
current Nevada practice patterns with
other states / regions
• Would allow for benchmarking across
health plans and identify best
practices
