    Kansas in 2006
    ◦ 4,824 and11.8% respectively

    NVSR, Vol 57, (7), January 7, 2009
Objectives
 Discuss Evidence Based Practice (EBP) &
  Best Practice Models
 Describe exemplary models of PNC in
  U.S.
 Define access & outcomes issues
 Explore challenges
 Enhance concept development
Adequacy of Prenatal Care (PNC)
in KS - 2007
   Kansas reported 39,055 live births [met definition of PNC]
    ◦ 77% received adequate or better
    ◦ 23% received less than adequate
        Of this subset 16% received Inadequate PNC
   Kansas counties with highest percentage of Inadequate Prenatal
    Care (IPNC)
    ◦ Scott, Seward, Hamilton, average 38%
    ◦ Significant clustering of IPNC in lower southwest KS counties
   Southeastern counties rate of IPNC
    ◦ Cherokee 31%
    ◦ Other surrounding counties range 9 – 28%
   Jefferson & Shawnee counties rate of IPNC were 11% and 14%
    respectively
   Urban county with largest index of IPNC – Wyandotte, 29%

KS APNC Utilization Index, 2007, CHES/KDHE publication, http://www.kdheks.gov/ches/

Benefits of PNC
   Early and ongoing PNC can improve
    pregnancy outcomes by:
    ◦   Assessing health risks
    ◦   Providing health care advice
    ◦   Assisting in supportive services
    ◦   Managing chronic and pregnancy-related
        health conditions

NVSR, Vol 57, (7), January 7, 2009
What is EBM/EBP?
   Evidence based medicine
    is a systematic approach
    to clinical problem
    solving which allows the
    integration of the best
    available research
    evidence with clinical
    expertise and patient
    values.


    (Sackett DL, Strauss SE,
    Richardson WS, et al. Evidence-
    based medicine: how to practice
    and teach EBM. London:
    Churchill-Livingstone, 2000)
An example in KS
   Hunter Health Clinic,
    Wichita
    ◦ Comanzando Bien
      prenatal care program
      with focus on Spanish
      speaking pregnant
      women diagnosed with
      Gestational Diabetes
    ◦ Funded by the KS
      Chapter MOD and
      other agencies
   Other EBP examples

Five Step Model of Evidence-
Based Practice
 ◦ Convert information needs into answerable
   questions
 ◦ Track down with maximum efficiency the best
   evidence with which to answer them
 ◦ Critically appraise that evidence for its validity
   and usefulness for your desired outcome
 ◦ Apply the results of this appraisal to your
   practice/project
 ◦ Evaluate your performance
Create your Question
 How would you describe a group of
  patients you are interested in OR a
  particular problem of interest?
 What are the most important
  characteristics of the population?
    ◦ This may include the primary topic, or co-
      existing conditions.
    ◦ Consider how gender, age, race, payer status,
      religion, SES or other variables influence the
      desired outcome.
Determine an intervention,
prognostic factor or exposure
 Which main intervention is most
  relevant?
 What do you want to do for the patient?
  Improve access? Improve outcomes?
  Provide minimal services?
 What factors may influence the outcome?
    ◦ Co-existing problems?
   Is there an influencing exposure delaying
    care?
    ◦ Substance abuse, others
Comparisons of Interest
 What is the main alternative to compare
  with the intervention?
 Are you trying to decide between two
  outcomes:
    ◦ an outcome with no intervention vs. usual
      care
    ◦ or two pilot interventions
    ◦ or between multi-site outcomes
   Your clinical question does not always
    need a specific comparison.
Outcomes
 What can you hope to accomplish,
  measure, improve or affect?
 What are you trying to do for the
  patient?
    ◦ Relieve…
    ◦ Reduce…
    ◦ Improve…
So a question might be…
   “In pregnant patients
    with no insurance, is
    access to care through
    coordinated, regionalized
    services among LPHDs
    effective in reducing the
    rate of late entry into
    prenatal care?”
   See worksheet FSU
    College of Medicine
    Library
   Question building…
What are AMCHP Best Practice
Models? (2004)
 AMCHP defines “best practices" as a continuum
  of practices, programs and policies ranging from
  promising to evidence-based to science-based.
 A best practice could focus on the health of
  women, adolescents, young children, families, or
  children with special health care needs.
 It could address mental health, data and
  assessment, financing, program integration,
  workforce development, emergency
  preparedness, family involvement, or a public
  health issue.
Resources for MCH Best Practices
   MCH national database are materials published in
    2000 or later that are program practices evaluated
    to be effective, or best practices, in a variety of
    topics, including community programs, women's
    health, infant health, and others.

Searching the Academic Literature
   There are literally millions of published
    reports, journal articles, correspondence and
    studies available to clinicians.
   Choosing the best resource to search is an
    important decision.
   Large search engines will give you access to
    the primary literature.
    ◦ CINNAHL, PubMed, OVID, MEDLINE
   The Cochrane Library database provides
    access to systematic reviews which help
    summarize the results from a number of
    studies.
How to do an effective search
 If you are not familiar with searching
  PubMed, you may want to use the PubMed
  tutorial at
  http://www.nlm.nih.gov/bsd/pubmed_tutorial
  /m1001.html
 If you are not familiar with searching
  MEDLINE in OVID, you may want to use the
  OVID tutorial at
  http://www.mclibrary.duke.edu/training/ovid
 You can even try GOOGLE SCHOLAR as a
  search engine
EBP Tools: Hierarchy of rigor
Guideline Recommendation and
Evidence Grading (GREG)
   Evidence grade:
    ◦ I (High): the described effect is plausible, precisely
      quantified and not vulnerable to bias
    ◦ II (Intermediate): the described effect is plausible but is not
      quantified precisely or may be vulnerable to bias
    ◦ III (Low): concerns about plausibility or vulnerability to
      bias severely limit the value of the effect being described
      and quantified
   Recommendation grade:
    ◦ A (Recommendation): there is robust evidence to
      recommend a pattern of care
    ◦ B (Provisional recommendation): on balance of evidence, a
      pattern of care is recommended with caution
    ◦ C (Consensus opinion): evidence being inadequate, a
      pattern of care is recommended by consensus
Common reporting terms
   Confidence Intervals are calculated on
    the results of the data to show the
    strength or weakness of the evidence.
    ◦ A 95% CI [range] means that if you were to
      repeat the same clinical trial a hundred times
      you can be 95% sure that the data would fall
      within the calculated range.
   Odds Ratio describes the odds of an
    experimental patient suffering an adverse
    event relative to a control patient.
and Definitions
   p Value refers to the probability that any
    particular outcome would have arisen by chance.
    ◦ The smaller the p value the less likely the data was by
      chance.
    ◦ Standard scientific practice, usually deems a p value of
      less than 1 in 20 (expressed as p=.05) as "statistically
      significant"
    ◦ The smaller the p value the higher the significance.
    ◦ A p value of p=.01 (less than 1 in 100) is considered
      "statistically highly significant"
   Relative Risk is the risk of developing a disease
    in the exposed group divided by the risk of
    developing the disease in the unexposed group.

                  A Community Based
                  Research & Training
                  Project designed to
                  improve access to
                  services for low-
                  income pregnant
                  women and children.
IPN Background
 In 2002, after competing with more than 70 cities
  throughout the nation, Indianapolis was one of
  four chosen to participate in a community-based
  research project, known nationally as Friendly
  Access, and locally as Indiana Access.
 This community-based research project is
  governed by the principle that the way in which
  people are treated plays a role in whether
  they access and continue to participate in
  primary and preventive health services, including
  prenatal care.
 Based on the Disney Model for Customer Service
Indiana Access Key Findings:
   Handout from Indiana Perinatal Network

Arizona Perinatal Health Initiative
on early PNC
 A crucial step to improving prenatal care
  utilization is the identification of pregnant women
  early in the pregnancy (i.e. before conception or
  within the first trimester).
 Outreach efforts are also crucial to assure that
  pregnant women receive consistent prenatal care.
 Identification and outreach activities work hand-in
  hand.
    ◦ For example, identifying high-risk pregnancies and
      providing outreach activities to assure consistent
      prenatal care utilization among high-risk pregnancies
      will result in better birth outcomes.
Arizona activities increase early
access to PNC
   Funded 15 high priority     Interventions include:
    health departments.

Factors Influencing Outcomes!
Outcome Measures – Common
Concerns
 Where do you find reliable measures?
 What is a comparable benchmark?
 How long should it take?
 What if I can’t replicate the same
  interventions?
 It might cost more than the accessible funds
  available.
 The stakeholders might not be interested.
 We don’t have enough human resources to
  conduct the project.
Creating Process/Outcome
Measures
 Seek usefulness, not
  perfection.
 Use small or
  repeated samples.
 Measure over
  specified time and
  over a wide range of
  conditions.
 Include quantitative
  and qualitative
  measures
PNC Determinants & Outcomes
   Goals of 90 percent have been set both
    for care beginning in the first trimester of
    pregnancy and for early and adequate
    prenatal care, as part of the Healthy People
    2010 program.

**No goal has been set for reducing late or
  no prenatal care.

Comments from Rural KS
  “I am from a small town in rural KS which has a huge
  population of people without insurance. I recently
  worked at a hospital where women frequently came
  in to labor with no prenatal care whatsoever. This was
  because they could not afford insurance. Some had no
  complications, but many had complications that could
  have been prevented. Many just needed medications
  and could not afford them. How can this be
  happening to women and babies in America? This is a
  HUGE problem that needs to be addressed and
  changed.”
