  3. Objectives • To summarize the relationship of maternal smoking and secondhand smoke exposure to maternal & infant health 2. To describe current best practice treatment for tobacco use, dependence and exposure 3. To discuss successes and challenges in treating tobacco use in pregnancy

  4. Health effects of smoking during pregnancy • Tobacco use is the most important modifiable cause of adverse pregnancy outcomes in the U.S. (Fang, 2004) • Smoking accounts for 20% of low birth weight deliveries (<2500 grams), 8% of preterm births and 5% of all perinatal deaths (Orleans, 2001)

  5. Health effects of smoking during pregnancy • Fetus is exposed to harmful chemicals such as tar, nicotine and CO • CO lowers the amount of oxygen received • Nicotine is a vasoconstrictor: less oxygen and nutrients reach the fetus (ACOG, 2011)

  6. Health effects of smoking during pregnancy • Greater risk of ectopic pregnancy, pre-term delivery, stillbirth, and low birth weight (Dietz, 2010) • Continued risk from secondhand smoke after birth: sudden infant death syndrome (SIDS), asthma, infantile colic and childhood obesity (Li, 2005, Sondergaard, 2001, von Kries, 2002); cognitive, emotional and behavioral problems in children (HHS, 2006, ACOG, 2005)

  7. Health effects of smoking during pregnancy Low birth weight is associated with increased risk for neonatal, perinatal and infant morbidity and mortality (CDC, Surgeon General’s Report, 2010)

  12. Effective Interventions- Pregnant Patients Brief health educator discussion of risks (3-5 min) + advised of cessation class+ pregnancy-specific self-help materials mailed weekly for 7 wks . Brief MD risk advice (2-3 min.); Video about risks, barriers, and quitting tips + one 10-minute session by CNM + self-help manual; and follow up letters. Pregnancy–specific self-help materials (Pregnant Woman’s Guide To Quit Smoking) + one 10- minute counseling session with a health educator. Cessation counseling:15-minute session-how to use pregnancy- specific self-help materials (Guide—Windsor et al., 1985); follow up MD letter + social support + buddy letter + contract + tip sheet. Windsor, et al (2000) PHASE III - AJOb/Gyn SCRIPT Methods: Guide & Commit to Quit Video 10 min.) & Patient Counseling (5 min.).

  13. U.S.P.H.S. Clinical Practice Guidelines, 2008 Update • 1. Pregnant smokers should be offered face- to-face psychosocial interventions that exceed minimal advice to quit (Strength of evidence = A) (HHS, 2008) • 2. Clinicians should offer effective tobacco dependence interventions to pregnant smokers at the first prenatal visit as well as throughout the course of pregnancy (Strength of evidence = B)

  14. U.S.P.H.S. Clinical Practice Guidelines, 2008 Update • 1. Evidence for Psychosocial interventions n = 8 studies: usual care (<3 minutes, self-help material, referral) vs. psychosocial intervention with intensive counseling

  15. U.S.P.H.S. Clinical Practice Guidelines, 2008 Update 1. Components of Psychosocial interventions • MD advice (2-3 minutes); video on risks, barriers to and tips for quitting; midwife counseling (10 minutes); self-help manual; follow-up letters (Walsh, 1997) • Pregnant Woman’s Self-Help Guide to Quit Smoking; counseling (10 minutes) (Windsor, 1985, 1993) • 90-minute counseling; bimonthly follow-up phone calls; monthly calls after delivery (Dornelas, 2006)

  16. U.S.P.H.S. Clinical Practice Guidelines, 2008 Update 2. Clinical practice suggestions for assisting pregnant smokers in quitting ASK:assess tobacco use status using a multiple-choice question to improve disclosure (e.g. smoke same #, smoke less #, quit before finding out I was pregnant) ADVISE: Motivate quit attempts by providing educational messages about health impact ASSESS: Assess the patient’s willingness to quit

  17. U.S.P.H.S. Clinical Practice Guidelines, 2008 Update 2. Clinical practice suggestions for assisting pregnant smokers in quitting ASSIST: Provide self-help materials (book, video) ARRANGE: Arrange for follow-up assessments throughout pregnancy

  18. U.S. P.H.S. Clinical Practice Guidelines, 2008 Update • Rationale for assisting pregnant smokers during prenatal visits • Many women are motivated to quit during pregnancy; 46% of smokers quit directly before or during pregnancy (Colman, 2003) • *Up to 60% of those who quit during pregnancy will relapse within 6 months postpartum, and 80-90% by 12 months postpartum (Floyd, 1993, Fingerhut, 1990) • Health benefits result from quitting at any time (Husten, 2008, England, 2001, Lieberman, 1994, DiClemente, 2000)

  19. U.S. P.H.S. Clinical Practice Guidelines, 2008 Update • NRT for pregnant smokers? • U.S. P.H.S. Clinical Practice Guidelines • Evidence on both safety and effectiveness of NRT is inconclusive • Nicotine may contribute to adverse effects of smoking during pregnancy and result in injury to the fetus (Jacobsen, 2007, Ginzel, 2007, Slotkin, 2007) • Cases should be considered in context – nicotine from NRT vs. nicotine from cigarettes (plus 4,000 chemicals and toxins)

  20. “Behavioral and Pharmacotherapy Treatment Strategies for Pregnant Smokers: Issues for Clinical Practice” R. Windsor, PhD, MPH, C. Oncken, MD, J. Henningfield, PhD, K. Hartmann, MD, PhD, and N. Edwards, PhD, RN., J. of the American Medical Women’s Association, Vol. 55(5), 304-309, 2000. Conclusion: The judicious use of NRT medications may significantly reduce harm to the infants of heavy smokers. More evidence derived from large population-based research, however, is needed to provide guidance to the physician about NRT eligibility, dose, scheduling, and effectiveness in clinical practice. ---------------------------------------------------------------------------------------- “Pharmacotherapy for Smoking Cessation during Pregnancy” Benowitz, Neal., Dempsey, Delia. Nicotine & Tobacco Research, Vol.6, Supp. 2, April, 2004, S189-S202. Conclusion: Clinicians should consider the use of nicotine replacement therapies as an adjunct to smoking cessation in pregnant women who cannot quit smoking with behavioral treatments alone. Available clinical trial data suggest that nicotine replacement therapy is safe during pregnancy, although its efficacy in aiding cessation has not been demonstrated. --------------------------------------------------------------------------------------------------------------------- Coleman, et al, “A RCT of NRT-Patches in Pregnancy”, NEJM, March 1, 2012 E NRT Group = 521- 9.4% vs C Group = 529 – 7.6% (NS) 20

  21. “Nicotine Replacement and Behavioral Therapy for smoking cessation in pregnancy”K.Pollak, et al., Vol.33, No.4, 2007, American Journal of Preventive Medicine Methods and Results Eligibility: ≥ 5 CPD, 13-25 weeks gestational age, ≥ 18 years old Intervention Group: 6 counseling sessions + NRT (patch, gum or lozenge) Control Group: 6 counseling sessions Measurement: saliva cotinine and self-report -------------------------------------------------------------------------------------------------------- Behavioral Impact: At 7 weeks, the intervention group had a 24% quit rate, compared to 8% in the control group. At 3 months postpartum, the intervention group had a 20% quit rate, compared to 14% in the control group.

  22. “Nicotine Gum for Pregnant Smokers: a RCT” C. Oncken , et al. Vol. 112, No. 4, 2008, Obstetrics & Gynecology Methods and Results --------------------------------------------------------------------------------------- Eligibility: > 1 cigs per day, < 26 weeks gestational age, > 16 years old Intervention Group: Two, 35-min counseling sessions, 2mg nicotine gum Control Group: Two, 35-min counseling sessions, placebo gum Measurement: 1st , 2nd, 3rd, 4th, 5th visit, based on CO & Self Report Process: 71% of the intervention group attended visits. 60% of the control group attended visits. Gum use did not differ significantly between the groups. Behavioral Impact: Quit rate for intervention group was 18.0%, compared to 14.9% for the control group. Birth weight for the intervention group was 3287g, compared to 2950g for the control group.

  36. “Accuracy of Self-Reported Smoking Status Assessed by CotinineTest Strips” • D. Parker, T. Lasater, R. Windsor, et al. (2002). Nicotine & Tobacco Research, Vol. 4, pp. • 305-09. (New England SCRIPT Trial) • -------------------------------------------------------------------------------------- • We evaluated a new urine cotinine test (CT) strip gas • chromatography (GC) and self-reports to assess smoking • status in pregnancy (n = 95) from 22 sites in MA, CT, and RI. • The 1st study to evaluate the accuracy of CT strip--(NicAlertTM). • CT strips confirmed smokers with a very high level of agreement (97% = 100 ng/ml and 97% = 250 ng/ml cutoff) and non- smokers with a moderate level of agreement (79% = 100 ng/ml and 86% = 250 ng/ml cutoff). • CT strips + self-reports were almost 100% accurate. • A larger trial is needed to evaluate the validity of the CT strip, compared to GC and self report. -------------------------------------------------------------------

  37. LITERATURE SYNTHESIS ------------------------------------------------------------------------------------- Recommended VALID Assessment of smoking status in Prenatal Care includes: Patient Self Reports + Biomarker ------------------------------------------------------------------------------------------------------- A. Carbon Monoxide (CO): >8 PPM is considered smoker B. Urine Cotinine Dipstick: >100 ng/ml is considered smoker C. Saliva Cotinine Strips-Dipstick (NicAlert): > 50 ng/ml is considered smoker D. Saliva or Urine Cotinine Test : 7-10 days in Lab; Saliva: > 20 ng/ml is considered smoker, & Urine: > 80- 100ng/ml is considered smoker ------------------------------------------------------------------------------------

  38. Discussion of Measurement --------------------------------------------------------------- What evidence is available that regular prenatal care staff (RN/SW) can deliver the SCRIPT Program with fidelity for > 1 year: A Process Evaluation Model (PEM)?

  39. Steps to plan a SCRIPT Dissemination Program for a Prenatal Care System, Regular Providers and Population of Pregnant Smokers? ----------------------------------------------------------------- What are we doing now and what/why do we want to introduce new, “Best Practice” methods- procedures into our Prenatal Care Program and Ob Practices: A Multi-Level Challenge?
