• Duration of pregnancy is no longer “9” months, it’s
“12” months
ACOG& AAP: prenatal care before conception
• PCC: Concept has evolved over the last several decades Form of primary care& prevention

Definition
A set of interventions that
aim to identify& modify (biomedical,
behavioral& social) risks to a woman’s
health or pregnancy outcome
through prevention& management (CDC,
2006)
Aboubakr Elnashar

Goal
• Goal should be realistic
Identify pre-existing conditions
that may affect an anticipated
pregnancy
Intervention(s) that could lead to
more favorable outcome
Aboubakr Elnashar

Currently: Poor pregnancy outcomes Women enter pregnancy “at risk” for
adverse outcomes We intervene too late There is consensus that: Intervening before pregnancy:
improve outcomes

Early ANC is too late
1. To Prevent Some Birth Defects
Critical period of teratogenesis: D17 to D56 Heart: begins to beat at 22 ds after conception
Neural tube: closes by 28 ds after conception
Palate: fuses at 56 ds after conception
2. To Prevent Implantation Errors
3. To restore allostasis: Maintain stability through change An important objective of PCC is to restore allostasis to women’s health before pregnancy

Components CDC, 2007
I. Risk Assessment
II. Health promotion
III. Interventions
Aboubakr Elnashar
12
A. Risk assessment I. Reproductive life plan: If she plans to have children? How long she plans to wait until she becomes pregnant? Plan, based on: her values& resources, to achieve those goals
Aboubakr Elnashar
13
II. History 1. Reproductive history:
Previous adverse outcomes:
infant death, fetal loss,
birth defects, low birth weight, PTL 2. Medical history: Rheumatic heart disease Thromboembolism Autoimmune diseases Hypertension Diabetes
Aboubakr Elnashar
14
3. Medication use:
Current medication
Avoid FDA
Category X: Estrogen, androgens,Aminopterin, isotretinoin,Thalidomide
Category D: Phenytoin, valporic acid, diazepam, Imipramine, captopril, thiazides, Spironolactone, coumarine, chlorpropamide, Progestins, tetracyclin, streptomycin, Quinine, methotrexate, vinblastin, Azathioprine.
unless maternal benefits outweigh fetal risks;
Over-the-counter medications, herbs& supplements
Aboubakr Elnashar
15
4. Substance abuse: Tobacco Alcohol Drug use 5.Toxins& teratogenic agents: At home, in the neighborhood, in the workplace: heavy metals, solvents, pesticides, endocrine disruptors, allergens
Aboubakr Elnashar
16
II. Physical examination: 1. Nutritional assessment: Assess the ABCDs of nutrition: anthropometric factors (e.g., BMI) biochemical factors (e.g., anemia) clinical factors dietary risks 2. Focus on
Periodontal,
thyroid, heart,
breast,
pelvic examination
Aboubakr Elnashar
17
III. Screening 1. Infections &immunizations:
Screen for periodontal, urogenital & STD as indicated;
Update immunization with hepatitis B, rubella, varicella,
Tdap,HPV& influenza vaccines as needed
Aboubakr Elnashar
18
2. Genetic screening:
Based on:
family history
ethnic background
age
Offer cystic fibrosis& other carrier screening as indicated
Aboubakr Elnashar
19
3. Psychosocial: Screen for depression, anxiety, domestic violence major psychosocial stressors
Aboubakr Elnashar
20
4. Laboratory testing:
Testing should include
CBC;
urinalysis;
blood type& screen
When indicated screen for
Rubella, syphilis, hepatitis B,HIV, gonorrhea, chlamydia
Diabetes
Thyroid Dysfunction
Cervical cytology
Aboubakr Elnashar
21
B. Health promotion 1. Family planning:
Based on the patient’s reproductive life plan
Effective contraceptive use
Discuss emergency contraception
Aboubakr Elnashar
22
2. Healthy weight & nutrition:
Ideal BMI: 20 to 26.0 kg/m2
Exercise
Nutrition
Macro& micronutrients:
Getting “five a-day”: 2 servings of
fruit +3 servings of vegetables
Daily multivitamin that contains
folic acid
Aboubakr Elnashar
23
3. Healthy behaviors: Nutrition
Exercise,
Safe sex
Effective contraceptive use
Dental flossing
Preventive health services
Discourage risky behaviors:
Douching
Not wearing a seatbelt,
Smoking:
use the five A’s [Ask, Advise, Assess, Assist, Arrange] for smoking cessation Alcohol
Substance abuse
Aboubakr Elnashar
24
4. Healthy environments:
Discuss household, neighborhood& occupational
exposures to heavy metals, organic solvents, pesticides,
endocrine disruptors& allergens;
Give practical tips such as how to avoid exposures
Aboubakr Elnashar
25
5. Stress resilience: Promote nutrition, exercise, sufficient sleep, and relaxation techniques; Address ongoing stressors (e.g., domestic violence) Identify resources to help the patient develop problem solving and conflict-resolution skills, positive mental health, and strong relationships 6. Interconception care: Promote breastfeeding, placing infants on their backs to sleep to reduce the risk of sudden infant death syndrome, positive parenting behaviors, and the reduction of ongoing biobehavioral risks
Aboubakr Elnashar
26
C. Interventions
1. Folic acid supplementation
Reduces NTD by two thirds.
2. Rubella vaccination
protection against congenital rubella syndrome.
3. Hepatitis B vaccination for at risk women:
Prevents transmission of infection to infants
Eliminates the risks to the women of hepatic failure, liver
carcinoma, age cirrhosis& death due to HBV infection.
Aboubakr Elnashar
27
4. Diabetes management: reduces birth defects among infants of diabetic women.
5. Hypothyroidism: protects proper neurological development.
6. HIV/AIDS screening: Allows for timely treatment Provides women (or couples) with additional information
that can influence the timing of pregnancy& treatment.
Aboubakr Elnashar
28
7. STD screening& TT Reduces the risk of ectopic pregnancy, infertility, chronic
pelvic pain associated with Ct& NG
Reduces risk to a fetus of fetal death or physical&
developmental disabilities, including mental retardation&
blindness.
8. Maternal PKU management: Prevents babies from being born with PKU-related
mental retardation.
Aboubakr Elnashar
29
9. Switching women off Oral anticoagulant: avoids harmful exposure.
10. Antiepileptic drug: Changing to a less teratogenic tt reduces harmful
exposure.
11. Accutane (isotretinoin) use management: Preventing pregnancy for women who use OR
Stop before conception
:eliminates harmful exposure.
Aboubakr Elnashar
30
12. Smoking cessation: Prevent:
PTL
low birth weight
other adverse perinatal outcomes.
13. Eliminating alcohol use Prevents fetal alcohol syndrome
other alcohol-related birth defects.
14. Obesity control: Reduces the risks of
NTD, PTL, DM, CS, Hypertension
Thromboembolic disease Aboubakr Elnashar

PPC for men • Alcohol
May be associated with physical& emotional abuse
May decrease fertility
• Genetic Counseling
• Occupational Exposure
- lead
• STD
– Syphilis, herpes, HIV

Aboubakr Elnashar
33
There is evidence that individual components of PCC work:
• Rubella vaccination
• HIV/AIDS screening
• Management and control of:
– Diabetes
– Hypothyroidism
– PKU
– Obesity
• Folic Acid supplements
(level 2)
• Avoiding teratogens:
– Smoking

Clinical Practice Guidelines
Aboubakr Elnashar
35
Clinical practice guidelines for PCC of specific maternal health conditions have been developed by professional organizations:
• American Diabetes Association (Diabetes -2004)
• American Association of Clinical Endocrinologists (Hypothyroidism – 1999)
• American Academy of Neurology (Anti-epileptic drugs)
• American Heart Association/American College of
Cardiologists (Anti-epileptic drugs - 2003)

ACOG/AAP (2002)
All health encounters during a woman’s reproductive
years, particularly those that are a part of PCC
should include counseling on appropriate medical
care and behavior to optimize pregnancy outcomes.
ACOG/AAP Guidelines for perinatal care, 5th edition, 2002

USPHS
“Every woman (and, when possible, her partner)
contemplating pregnancy within one year should consult
a prenatal care provider. Because many pregnancies
are not planned, providers should include preconception
counseling, when appropriate, in contacts with women
and men of
reproductive age….Such care should be integrated into
primary care services.”
USPHS Expert Panel on the Content of Prenatal Care, 1989

Barriers
Aboubakr Elnashar
40
I. Patient Aspects
• High rate of unintended pregnancies
• Ignorance about importance of good health habits prior to
conception
• Limited access to health services in general.
Aboubakr Elnashar
41
II. Provider Aspects
• Feeling of having inadequate
knowledge
• Perception of PCC being time
consuming
• Lack of awareness of how to
integrate PCC into practice
• Concern about insurance reimbursement.
Aboubakr Elnashar
42
III. Other barriers:
• Availability of contraceptives
• Health Insurance Coverage
• Out of Pocket Expenses.

Implementation
Aboubakr Elnashar
44
Who Should Get PCC? • PCC should be provided to all reproductive age
individuals
Aboubakr Elnashar
45
WHO TO PROVIDE?
– OB-GYNs
– Pediatricians, Family Medicine, Internists,
– Nurses
– Genetic Counselors
– Health Educators
Aboubakr Elnashar
46
Why Should Ob/Gyns be Concerned with
PCC?
• OB/GYN’s
have the most frequent contact with women
of childbearing age
are aware of prior poor pregnancy outcomes
Responsible for ANC
already have the knowledge& are applying it
advantage to improve pregnancy outcomes
Aboubakr Elnashar
47
How PCC can be Integrated into Practice? I. OB-GYNs 1. WHC:
- Our best opportunity
- Single or multiple visits
- Ask about reproductive life plan
- If she plans to have child in next 1-2 yrs: she& husband should return for full visit.
2. Negative pregnancy test: an opportunity for PCC
3. Family planning encounter
4. Infertility evaluation
5. Following a poor pregnancy outcome
