Protocols for High-Risk Pregnancies. Группа авторов
of three questions: 1) Have you ever smoked marijuana? 2) In the month before you knew you were pregnant, how many beers, how much wine, or how much liquor did you drink?, and 3) Have you ever felt that you needed to cut down on your drug or alcohol use? Scoring requires tallying the number of affirmative responses (0 = low risk, 1 = moderate risk, 2–3 = high risk).
Screening for alcohol use during pregnancy allows clinicians to stratify risk in women according to their patterns of use. It is recommended that women at low risk should receive brief counseling regarding the risk of alcohol use during pregnancy. Women classified as moderate risk should receive a brief intervention (described below), and women at high risk should be referred for specialized substance abuse treatment.
Providers must also be aware of the possibility of concurrent psychiatric illness, as women with risky alcohol use are more likely to suffer from psychiatric illness, and women with untreated psychiatric illness are more likely to use alcohol (and other substances) during pregnancy. Consultation with mental health professionals is indicated and attending to co‐morbid psychiatric illness can increase the likelihood of abstinence during pregnancy and improve compliance with prenatal care.
Intervention and referral to treatment
Screening, brief intervention, and referral to treatment (SBIRT) is a comprehensive, integrated public health approach used to identify and deliver services to those at risk for substance use disorders and has the potential to reduce the burden of substance use in pregnancy. SBIRT may be implemented in a variety of healthcare settings and adapted for culturally diverse populations. The Department of Health and Human Services Substance Abuse and Mental Health Services Administration (SAMHSA) provides many useful materials to facilitate implementation of SBIRT which consists of three basic components.
1 Screening by a health professional using validated instruments can quickly assess the severity of substance use and identify the appropriate level of care.
2 Brief intervention focuses on increasing insight and awareness regarding substance use and motivation toward behavioral change.
3 Referral to treatment provides those identified as needing more extensive treatment with access to specialty care.
After screening, women at moderate risk should receive a brief intervention which typically involves counseling sessions, approximately five minutes in length, tailored to the severity of the identified alcohol problem. During the first meeting, the provider should state her/his concerns and help to set goals. Educational materials should be provided. Routine follow‐up is essential; subsequent visits should involve encouragement, information, and reevaluation of goals. Wright and colleagues (Table 1.1) have modified SBIRT for use in pregnant women, leveraging the motivation inherent in the desire to have a healthy pregnancy.

| Raise subject | “Thank you for answering my questions – is it OK with you if we talk about your answers?” “Can you tell me more about your past/current drinking or drug use? What does a typical week look like?” |
| Provide feedback | “Sometimes patients who give similar answers are continuing to use drugs or alcohol during their pregnancy.” “I recommend all my pregnant patients not to use any alcohol or drugs, because of the risk to you and to your baby.” |
| Enhance motivation | “What do you like and what are you concerned about when it comes to your substance use?” “On a scale of 0–10, how ready are you to avoid drinking/using altogether? Why that number and not a lower number?” |
| Negotiate plan | Summarize conversation. Then: “What steps do you think you can take to reach your goal of having a healthy pregnancy and baby?” “Can we schedule a date to check in about this next time?” |
Women who are unable to reduce or eliminate consumption of alcohol during pregnancy should be referred for more intensive intervention.
Conclusion
Alcohol consumption during pregnancy is relatively common, with the most recent surveys indicating that 11.5% of pregnant women in the US report consuming alcohol during pregnancy. While heavy alcohol use and binge drinking pose the greatest risk to the fetus, lower levels of exposure to alcohol have been associated with birth defects, neurodevelopmental deficits, and fetal alcohol spectrum disorders. OB‐GYNs are ideally positioned to screen women for risky alcohol use both before and during pregnancy and can educate women regarding the risks of alcohol use during pregnancy and initiate interventions which significantly decrease the use of alcohol during the perinatal period.

Clinical significance
Although cigarette smoking rates have continued to decline since the turn of the century, approximately 8% of women will smoke cigarettes sometime during their pregnancy in the US.
Tobacco exposure in pregnancy is associated with an increased rate of adverse outcomes such as fetal growth restriction, preterm birth, placenta previa, abruptio placentae, congenital anomalies such as cleft lip/palate, and perinatal mortality. It is estimated that up to 8% of preterm births, 19% of term deliveries of low‐birthweight infants, and 7% of preterm‐related infant deaths can be attributed to smoking during the pregnancy. The effects are not limited to cigarette smoking, as researchers have identified infants born to mothers who use smokeless tobacco, have similar levels of nicotine exposure, low birthweight, and preterm birth as the infants whose mothers smoked during pregnancy. Lastly, there has been a recent emergence of the use of electronic nicotine delivery systems or e‐cigarettes (also known as vaping), shifting many cigarette smokers to the use of e‐cigarettes. This electronic delivery system aerosolizes nicotine, releasing a vapor similar to traditional cigarette smoke, and 7% of women
