  1. Integration of AHRQ-Smoking Cessation or Reduction in Pregnancy Treatment Methods Maternity Care. Richard Windsor, MS, PhD, MPH Professor Department of Prevention and Community Health School of Public Health and Health Services George Washington University Medical Center 2175 K Street, NW Washington, DC 20037 (202) 416-0086

  2. TOPICS • Examine smoking status-trends during pregnancy and postpartum for the decade. • Discuss the validity of patient self reports. • Describe the AHRQ-SCRIPT methods. • Present meta-evaluation of cessation methods. • Estimate the behavioral impact on birth weight and cost benefit of effective methods. • A brief update on pharmacological treatment. • Discuss the integration of SCRIPT by MCO’s.

  3. Smoking Rates and Trends During Pregnancy: Validity? • 4 million births: 1990-2000 • CDC-PRAMS: Mailed Survey-PP • SAMSHA: Household Surveys • Patient Deception?

  4. Table 1 Smoking Rates During Pregnancy and Percent Change: 1990-2000 Years Total Black White Hispanic Other 1990 18.4% ---- ---- ---- ---- 1993 15.8% 15.9% 21.0% 6.7% 8.6% 1995 13.9% ---- ---- ---- ---- 1997 13.2% 10.6% 17.1% 4.3% 7.5% 1999 12.3% ---- ---- ---- ---- 2000 12.2% 9.1% 15.7% 3.7% 5.9% % Change -34% -43% -25.% -45% -46% < Smokers -240,000+ ---- ---- ---- ---- NCHS-NVSS-CDC, Vol. 48, No. 14, August 18, 2000 and Vol. 49, No. 7, August 28, 2001, Table 1, and Vol. 50,No.5, February 12, 2002, Table 32. + = Crude Estimate

  5. Table 2 Average Smoking Rates+ Among Women Ages 15-44 from 1990 to 2001* Smoking Rates Survey Pregnant Non-Pregnant * Cigarettes & Cigars in Last Month, National Household Survey on Drug Abuse, SAMHSA, Office of Applied Studies, Annual Reports: 1990 to 2000.

  6. Smoking and Low Birth Weight (LBW) Trends: CDC • LBW Rates: 6.97 (1990) to 7.80 (2000) • 1990: 276,000 LBW Infants • 2002: 316,000 LBW Infants • LBW Smokers: 11.90 - - Non-Smokers: 7.20 • Pregnant Smoker PAR = 30,000 LBW/10% • < 34% S Rate: ≤ 10,000 LBW Infants

  7. Table 3 LBW Rates by Self-Reported Smoking Status: 1990 to 2000 Black Excerpted Data – NCHS, NVSS, CDC, August 28,2001 & February 12, 2002—Estimated Data.

  8. Table 4 Patient Assessment of Smoking Status in Clinical Practice Assess pregnant woman’s tobacco use status using a multiple–choice question to improve disclosure. Many pregnant women deny smoking. A multiple-choice question format may improve disclosure. For example: Which best describes your cigarette smoking? • I smoke regularly now- about the same, as before finding out I was pregnant. • I smoke regularly now, but I’ve cut down since I found out I was pregnant. • I smoke every once in a while. • I have quit smoking since finding out I was pregnant . • I wasn’t smoking when I found out I was pregnant, and I don’t smoke now. AHRQ 2000 (P. 95).

  10. Smoking Status Assessment in Maternity Care: Periodicity • First Visit • Third or Fourth Visit • Post-Partum Visit • Biochemical Confirmation: CO Urine Cotinine Dipstick

  11. D. Parker, T. Lasater, R. Windsor, et al. (2002). The Accuracy of Self-Reported Smoking Status Assessed by Cotinine Test Strips. Nicotine & Tobacco Research: Vol 4, pages 305-309. We evaluated a new urine cotinine test (CT) strip, gas chromatography (GC) and a self-administered questionnaire to assess smoking status in pregnancy (n = 95).

  12. 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 plus self-reports provided a very accurate measure. • This was the first study to evaluate the CT strip, using the CT strip prototype. • A larger trial is needed to evaluate the validity of the CT strip, compared to GC and self report.

  14. Table 6 Examples of Effective Interventions With Pregnant Patients Brief health educator discussion of risks (3-5 minutes); advised of a free cessation class; and pregnancy-specific self-help materials mailed weekly for 7 weeks. Physician advice on risk (2-3 minutes); videotape with information on risks, barriers, and tips for quitting; midwife counseling in one 10-minute session; self-help manual; and follow up letters. Pregnancy–specific self-help materials (Pregnant Woman’s Guide To Quit Smoking) and one 10-minute counseling session with a health educator. Cessation skills and risk counseling in one 15-minute session by a health counselor; education on how to use pregnancy-specific self-help materials (same Guide as Windsor et al., 1985); follow up medical letter; social support with a buddy letter, a contract, and a tip sheet.

  15. The “Smoking Cessation and Reduction in Pregnancy Treatment” (SCRIPT) Model (1981-2001) was designed to be successfully integrated into patient education methods for women into public health and managed care organizations. The “effectiveness” of SCRIPT delivered as part of routine care by physicians, nurses social workers, and nutritionists has been rigorously evaluated.

  16. Figure 1 SCRIPT Model: Counseling Procedures For Pregnant Smokers PROCEDURE COMPLETED ASK AND ASESS: 1 minute 1. Document smoking status and cigarettes per day (cpd) A. Never smokerD.

  24. PREGNANCY Recommendation: Pharmacotherapy should be considered when a pregnant woman is unable to quit, and when the likelihood of quitting, with its potential benefits, outweighs the risk of pharmacotherapy and potential continued smoking. If the clinician and pregnant or lactating patient decide to use NRT pharmacotherapy, the clinician should consider: • Monitoring urine cotinine/CO levels to assess level of smoking activity. • Using medication doses at the low end of the effective dose range, and • Choosing a delivery system that yields intermittent, rather than continuous, drug exposure (e.g., gum rather than the patch). Because no NRT medications have been tested in pregnant women for efficacy in treating tobacco dependence, the relative ratio of risks to benefits is unclear. AHRQ, 2000 (Page 2).

  25. Integration of Guidelines into Practice for MCO’s • Science-Evidence Base: AHRQ/SCRIPT • Organizational Policy-Development • Training: Basic Counseling Skills • Practice-Patient Flow Analysis (PFA) • Practice Pilot Tests • Final Practice Guidance-Policy

  30. Aim #2 – Train SCRIPT maternity clinic staff to perform patient assessments and to deliver patient education methods. Maternity clinic staff will be able to: • Describe the process to introduce SCRIPT to patients; • Demonstrate how to assess smoking status using CO or urine dipsticks and interpret results to patients; • Demonstrate patient education skills and counseling by delivery of video, guide, patient education prescription forms and role plays; • Describe when and how to conduct follow-up assessments; • Describe how to translate the process of data collection into a simple cost analysis; and • Describe how to assess cessation and significant reduction.
