Brief intervention for alcohol use in pregnancy: a randomized trial

Psychosocial and medication interventions to stop or reduce alcohol consumption during pregnancy

BACKGROUND

Despite the known harms, alcohol consumption is common in pregnancy. Rates vary between countries, and are estimated to be 10% globally, with up to 25% in Europe.

OBJECTIVES

To assess the efficacy of psychosocial interventions and medications to reduce or stop alcohol consumption during pregnancy.

SEARCH METHODS

We searched the Cochrane Drugs and Alcohol Group Specialised Register (via CRSLive), Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, Web of Science, and PsycINFO, from inception to 8 January 2024. We also searched for ongoing and unpublished studies via ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). All searches included non-English language literature. We handsearched references of topic-related systematic reviews and included studies.

SELECTION CRITERIA

We included randomised controlled trials that compared medications or psychosocial interventions, or both, to placebo, no intervention, usual care, or other medications or psychosocial interventions used to reduce or stop alcohol use during pregnancy. Our primary outcomes of interest were abstinence from alcohol, reduction in alcohol consumption, retention in treatment, and women with any adverse event.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures.

MAIN RESULTS

We included eight studies (1369 participants) in which pregnant women received an intervention to stop or reduce alcohol use during pregnancy. In one study, almost half of participants had a current diagnosis of alcohol use disorder (AUD); in another study, 40% of participants had a lifetime diagnosis of AUD. Six studies took place in the USA, one in Spain, and one in the Netherlands. All included studies evaluated the efficacy of psychosocial interventions; we did not find any study that evaluated the efficacy of medications for the treatment of AUD during pregnancy. Psychosocial interventions were mainly brief interventions ranging from a single session of 10 to 60 minutes to five sessions of 10 minutes each. Pregnant women received the psychosocial intervention approximately at the end of the first trimester of pregnancy, and the outcome of alcohol use was reassessed 8 to 24 weeks after the psychosocial intervention. Women in the control group received treatment as usual (TAU) or similar treatments such as comprehensive assessment of alcohol use and advice to stop drinking during pregnancy. Globally, we found that, compared to TAU, psychosocial interventions may increase the rate of continuously abstinent participants (risk ratio (RR) 1.34, 95% confidence interval (CI) 1.14 to 1.57; I2 =0%; 3 studies; 378 women; low certainty evidence). Psychosocial interventions may have little to no effect on the number of drinks per day, but the evidence is very uncertain (mean difference -0.42, 95% CI -1.13 to 0.28; I2 = 86%; 2 studies; 157 women; very low certainty evidence). Psychosocial interventions probably have little to no effect on the number of women who completed treatment (RR 0.98, 95% CI 0.94 to 1.02; I2 = 0%; 7 studies; 1283 women; moderate certainty evidence). None of the included studies assessed adverse events of treatments. We downgraded the certainty of the evidence due to risk of bias and imprecision of the estimates.

AUTHORS' CONCLUSIONS

Brief psychosocial interventions may increase the rate of continuous abstinence among pregnant women who report alcohol use during pregnancy. Further studies should be conducted to investigate the efficacy and safety of psychosocial interventions and other treatments (e.g. medications) for women with AUD. These studies should provide detailed information on alcohol use before and during pregnancy using consistent measures such as the number of drinks per drinking day. When heterogeneous populations are recruited, more detailed information on alcohol use during pregnancy should be provided to allow future systematic reviews to be conducted. Other important information that would enhance the usefulness of these studies would be the presence of other comorbid conditions such as anxiety, mood disorders, and the use of other psychoactive substances.

Effectiveness of brief alcohol interventions for pregnant women: a systematic literature review and meta-analysis

BACKGROUND

Prenatal alcohol exposure (PAE) can result in a range of adverse neonatal outcomes, including Fetal Alcohol Spectrum Disorder (FASD). This systematic review and meta-analysis sought to investigate the effectiveness of brief interventions (BIs) in eliminating or reducing 1) alcohol consumption during pregnancy; and 2) PAE-related adverse neonatal outcomes; and 3) cost-effectiveness of BIs.

METHOD

We conducted a systematic literature search for original controlled studies (randomized control trials (RCTs); quasi-experimental) in any setting, published from 1987 to 2021. The comparison group was no/minimal intervention, where a measure of alcohol consumption was reported. Studies were critically appraised using the Centre for Evidence-based Medicine Oxford critical appraisal tool for RCTs (1). The certainty in the evidence for each outcome was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) (2). Meta-analysis of continuous and binary estimates of effect-size for similar outcome measures for BIs versus control groups were pooled and reported as mean difference (MD) Hedges' g and odds ratios (ORs), respectively.

RESULTS

In total, 26 studies, all from high income countries, met inclusion criteria. Alcohol abstinence outcome available in 12 studies (n = 2620) found modest effects in favor of BIs conditions by increasing the odds of abstinence by 56% (OR = 1.56, 95% confidence interval (CI) = 1.15-2.13, I² = 46.75%; p = 0.04). BIs effects for reduction in mean drinks/week (Cohen's d = - 0.21, 95%CI = - 0.78 to 0.36; p = 0.08) and AUDIT scores (g = 0.10, 95%CI = - 0.06 to 0.26; p = 0.17) were not statistically significant. Among seven studies (n = 740) reporting neonatal outcomes, BI receipt was associated with a modest and significant reduction in preterm birth (OR = 0.67, 95% CI = 0.46-0.98, I² = 0.00%; p = 0.58). No statistically significant differences were observed for mean birthweight or lower likelihood of low birth weight (LBW). Certainty in the evidence was rated as 'low'. No eligible studies were found on cost-effectiveness of BIs.

CONCLUSION

BIs are moderately effective in increasing abstinence during pregnancy and preventing preterm birth. More studies on the effectiveness of BIs are needed from low- and middle-income countries, as well as with younger mothers and with a broader range of ethnic groups.

Substance Use During Pregnancy: A Comparative Review of Major Guidelines

Importance

Substance use during pregnancy is a major health issue for both the mother and the fetus, but it also represents an important public health concern.

Objective

The aim of this review was to summarize and compare recommendations from recently published guidelines on substance use during pregnancy and especially regarding alcohol, smoking, and drug use.

Evidence Acquisition

A descriptive review of guidelines from the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, the World Health Organization (WHO), the Society of Obstetricians and Gynaecologists of Canada, and the American College of Obstetricians and Gynecologists on substance use was conducted. Regarding the term "substance use," the most recently published Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition substances were used.

Results

All the reviewed guidelines recommend appropriate counseling and screening women regarding alcohol, smoking, and drug use during the antenatal period, while the management options vary. More specifically, the prompt management of alcohol dependence is emphasized by all the guidelines except from the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, which makes no recommendation upon. The use of alcohol during breastfeeding should be avoided. Regarding smoking cessation, all guidelines recommend the use of certain psychosocial, behavioral interventions, and pharmacotherapy. All the guidelines, except the one from the WHO, suggest screening drug users for coexistent sexually transmitted infections. Brief interventions are considered beneficial, while a gradual decrease in benzodiazepines is suggested, as well as the discontinuation of marijuana and methamphetamine use. However, there is controversy regarding breastfeeding in those women as the WHO recommends in favor, whereas the Society of Obstetricians and Gynaecologists of Canada and the American College of Obstetricians and Gynecologists recommend against this practice. Finally, all the guidelines state that, following delivery, close monitoring of the neonate is needed.

Conclusions

The diversity of guidelines' recommendations concerning substance use reflects the different ways of the management of pregnant women during routine antenatal care due to absence of strong evidence. More research in the areas of dispute may allow the adoption of an international consensus, in order to early detect and appropriately manage pregnant women with harmful addictions.

Effectiveness of psychological interventions to reduce alcohol consumption among pregnant and postpartum women: a systematic review

This study aims to synthesise the available evidence on psychological interventions to reduce alcohol consumption among pregnant and postpartum women. Six electronic databases were searched to identify controlled studies targeting pregnant and postpartum women who drink or are at risk of drinking due to previous patterns of alcohol use. Controlled quantitative studies such as randomised controlled trials and quasi-experimental studies were included. The search was limited to peer-reviewed articles in English. The methodological quality of studies was assessed using the Cochrane risk of bias tool. A narrative synthesis of the findings was conducted. In total, 12,610 records were screened, and 11 studies were eligible for inclusion (9 with pregnant women, 2 with postpartum women). All studies were randomised controlled trials. Five studies had positive or partially positive primary outcomes of reductions in drinking or abstinence, and their interventions ranged from multi-session brief interventions to self-help manuals based on cognitive behavioural components. All studies showed considerable methodological limitations. Psychological interventions may be effective in promoting abstinence or reducing alcohol consumption among pregnant and postpartum women. Interventions that demonstrated some efficacy showed higher level of engagement with pregnant women compared to studies which delivered interventions in a single session. Paucity of evidence, inconsistency of outcomes, large heterogeneity in the interventions and methodological weaknesses limit the ability to make final conclusions about the overall effectiveness of these interventions. Findings highlight the need for better quality research on this topic.

Are psychosocial interventions effective in reducing alcohol consumption during pregnancy and motherhood? A systematic review and meta-analysis

BACKGROUND AND AIMS

Alcohol use by pregnant and parenting women can have serious and long-lasting consequences for both the mother and offspring. We reviewed the evidence for psychosocial interventions to reduce maternal drinking.

DESIGN

Literature searches of PsycINFO, PubMed and Scopus identified randomised controlled trials of interventions with an aim of reduced drinking or abstinence in mothers or pregnant women.

SETTING

Interventions were delivered in healthcare settings and homes.

PARTICIPANTS

Pregnant women and mothers with dependent children.

INTERVENTIONS

Psychosocial interventions were compared with usual care or no intervention.

MEASUREMENTS

The revised Cochrane risk-of-bias tool for randomised trials was used for quality assessments. Narrative synthesis summarised the findings of the studies with a subset of trials eligible for random-effects meta-analysis. General and alcohol-specific behaviour change techniques (BCTs) were identified to investigate potential mechanism of change.

RESULTS

Twenty-four studies were included (20 pregnancy, four motherhood). Because of quality of reporting, data from only six pregnancy and four motherhood studies could be pooled. A significant treatment effect was revealed by the meta-analyses of pregnancy studies regarding abstinence (OR = 2.31, 95% CI = 1.61, 3.32; P < 0.001) and motherhood studies regarding a reduction in drinking (standardised mean difference [SMD] = -0.20, 95% CI = -0.38, -0.02; P = 0.03). Narrative synthesis of the remaining trials yielded inconsistent results regarding intervention effectiveness. A wide range of BCTs were used, present in both effective and ineffective interventions. The most commonly used general and alcohol-specific BCTs included information about consequences, social support, goal setting and action planning.

CONCLUSIONS

In pregnant women identified as consuming alcohol, psychosocial interventions appear to increase abstinence rates compared with usual care or no intervention. Similarly, such interventions appear to lead to a reduction in alcohol consumption in mothers with dependent children. It is unclear that behaviour change techniques are contributing to these effects. Conclusions from randomised controlled trials are only meaningful if the behavioural outcome, population, setting, intervention and comparator are clearly reported. An important barrier when it comes to identifying effective behaviour change techniques is a widespread failure to provide enough information in study reports.

Pharmacotherapies for the Treatment of Alcohol Use Disorders During Pregnancy: Time to Reconsider?

It is generally recommended that medications only be used in pregnancy where the potential harms to both the mother and foetus are outweighed by the potential benefits. Despite the known harms associated with alcohol consumption during pregnancy, the use of medication for the treatment of pregnant women with an alcohol use disorder (AUD) appears to be rare. This is likely due to the lack of available data regarding the safety of these medications in pregnancy. We reviewed the literature and weighed up the harms associated with alcohol use and AUD during pregnancy with the potential benefits of medications for AUD in pregnancy, including acamprosate, naltrexone and disulfiram. There is little published evidence to support the safety of medications for AUD in pregnancy. However, from the research available it is likely that only disulfiram has the potential to cause serious foetal harm. While further research is required, acamprosate and naltrexone do not appear to be associated with substantial risks of congenital malformations or other serious consequences. Given the potential risks associated with alcohol consumption during pregnancy, the use of acamprosate and naltrexone should be considered for the treatment of pregnant women with AUD based on the current evidence base, although more research is warranted.

Prevention of Alcohol-Exposed Pregnancies and Fetal Alcohol Spectrum Disorder Among Pregnant and Postpartum Women: A Systematic Review

BACKGROUND

Prenatal alcohol exposure can result in a wide range of adverse health outcomes, including in some cases fetal alcohol spectrum disorder (FASD), a lifelong neurodevelopmental disorder. Thus, there is pressing need for effective interventions to prevent alcohol-exposed pregnancies (AEPs).

METHODS

A systematic review was undertaken to provide an up-to-date analysis of the current prevention literature. PubMed, Embase, CINAHL, and PsycINFO were searched for relevant English-language articles published from 1970 onward. Studies were eligible for the current systematic review if the interventions included pregnant and postpartum women and/or their support networks to prevent AEPs and FASD. Outcomes of interest included alcohol consumption, knowledge, contraceptive use, neonatal outcomes, family well-being or functioning, economics, and healthcare utilization outcomes.

RESULTS

Thirty-four peer-reviewed studies met the inclusion criteria. Fifteen studies employed brief intervention (BI) methods, 6 used long-term/intensive strategies, and 5 were educational interventions. A further 3 studies assessed counseling approaches, 2 evaluated multicomponent interventions, and 3 assessed nutritional supplementation interventions.

CONCLUSIONS

The current review identified variable results from available interventions to prevent alcohol use among pregnant and postpartum women. Preliminary evidence demonstrated that BIs may be effective among subgroups of pregnant women with higher initial alcohol consumption, those with partner involvement, and those who used alcohol and other substances concurrently. Some preliminary evidence relating to long-term interventions with pregnant women with polysubstance use emerged, specifically case management that not only focused on reduction in substance use, but also on addressing the complex interplay between health and social well-being of families. Overall, additional research is required to improve the effectiveness of preventative approaches during pregnancy and the postpartum period.

Identifying Effective Behavior Change Techniques for Alcohol and Illicit Substance Use During Pregnancy: A Systematic Review

Background

During pregnancy, consuming alcohol and using illicit drugs can have serious health implications for both mother and child. Behavioral change interventions, especially those underpinned by theoretical constructs, can be effective in reducing harmful substance use among pregnant women.

Purpose

To understand what type of behavior change mechanisms could be useful in reducing alcohol consumption or achieving abstinence from illicit drug use during pregnancy, this review aimed to identify behavior change techniques (BCTs), the smallest, active components of interventions that may be effective. It also aimed to establish the extent that psychosocial-based theories were used to inform intervention design.

Methods

To identify eligible randomized controlled trials (RCTs), five databases were searched electronically from the end search dates of the most recent Cochrane systematic reviews on behavioral interventions for each behavior, until March 2018. Within the RCTs, intervention descriptions were analyzed for BCT content and extent of theory use in the intervention design process and outcome measurements, in each trial, was established. “Effectiveness percentages,” the number of times a BCT had been a component of an effective intervention divided by the total number of interventions it had been used in, were calculated for BCTs used in two or more trials.

Results

Including all RCTs from the Cochrane reviews, and those published subsequently, nine alcohol and six illicit drug trials were identified. Interventions tested in four alcohol RCTs and no illicit drugs RCTs showed positive results. Subsequent data were extracted for alcohol consumption trials only. Thirteen BCTs showed “potential effectiveness” for alcohol consumption. Six of nine included alcohol trials reported using theory but not extensively.

Conclusions

Action planning, behavioral contract, prompts/cues, self-talk, offer/direct toward written material, problem solving, feedback on behavior, social support (unspecified), information about health consequences, behavior substitution, assess current readiness and ability to reduce excess alcohol consumption, goal setting (behavior), and tailor interactions appropriately are BCTs that could be useful in helping reduce alcohol consumption among pregnant women.

Medicaid Accountable Care Organizations and Childbirth Outcomes

Some states have adopted Accountable Care Organization (ACO) models to transform their Medicaid programs, but little is known about their impact on health care outcomes and costs. Medicaid ACOs are uniquely positioned to improve childbirth outcomes because of the number of births covered by Medicaid. Using Healthcare Cost and Utilization Project hospital data, we examined the relationship between ACO adoption and (a) neonatal and maternal outcomes, and (b) cost per birth. We compared outcomes in states that have adopted ACO models in their Medicaid programs with adjacent states without ACO models. Implementation of Medicaid ACOs was associated with a moderate reduction in hospital costs per birth and decreased cesarean section rates. Results varied by state. We found no association between Medicaid ACOs and several birth outcomes, including infant inpatient mortality, low birthweight, neonatal intensive care unit utilization, and severe maternal morbidity. Improving these outcomes may require more time or targeted interventions.

WFSBP * and IAWMH ** Guidelines for the treatment of alcohol use disorders in pregnant women

OBJECTIVES

These practice guidelines for the treatment of alcohol use disorders during pregnancy were developed by members of the International Task Force of the World Federation of Societies of Biological Psychiatry and the International Association for Women's Mental Health.

METHODS

We performed a systematic review of all available publications and extracted data from national and international guidelines. The Task Force evaluated the data with respect to the strength of evidence for the efficacy and safety of each medication.

RESULTS AND DISCUSSION

There is no safe level of alcohol use during pregnancy. Abstinence is recommended. Ideally, women should stop alcohol use when pregnancy is planned and, in any case, as soon as pregnancy is known. Detecting patterns of alcohol maternal drinking should be systematically conducted at first antenatal visit and throughout pregnancy. Brief interventions are recommended in the case of low or moderate risk of alcohol use. Low doses of benzodiazepines, for the shortest duration, may be used to prevent alcohol withdrawal symptoms when high and chronic alcohol intake is stopped and hospitalisation is recommended. Due to the low level of evidence and/or to low benefit/risk ratio, pharmacological treatment for maintenance of abstinence should not be used during pregnancy. At birth, foetal alcohol spectrum disorders must be searched for, and alcohol metabolites should be measured in meconium of neonates in any doubt of foetal alcohol exposure.

Screening and Behavioral Counseling Interventions to Reduce Unhealthy Alcohol Use in Adolescents and Adults: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Unhealthy alcohol use is common, increasing, and a leading cause of premature mortality.

OBJECTIVE

To review literature on the effectiveness and harms of screening and counseling for unhealthy alcohol use to inform the US Preventive Services Task Force.

DATA SOURCES

MEDLINE, PubMed, PsycINFO, and the Cochrane Central Register of Controlled Trials through October 12, 2017; literature surveillance through August 1, 2018.

STUDY SELECTION

Test accuracy studies and randomized clinical trials of screening and counseling to reduce unhealthy alcohol use.

DATA EXTRACTION AND SYNTHESIS

Independent critical appraisal and data abstraction by 2 reviewers. Counseling trials were pooled using random-effects meta-analyses.

MAIN OUTCOMES AND MEASURES

Sensitivity, specificity, drinks per week, exceeding recommended limits, heavy use episodes, abstinence (for pregnant women), and other health, family, social, and legal outcomes.

RESULTS

One hundred thirteen studies (N = 314 466) were included. No studies examined benefits or harms of screening programs to reduce unhealthy alcohol use. For adolescents (10 studies [n = 171 363]), 1 study (n = 225) reported a sensitivity of 0.73 (95% CI, 0.60 to 0.83) and specificity of 0.81 (95% CI, 0.74 to 0.86) using the AUDIT-C (Alcohol Use Disorders Identification Test-Consumption) to detect the full spectrum of unhealthy alcohol use. For adults (35 studies [n = 114 182]), brief screening instruments commonly reported sensitivity and specificity between 0.70 and 0.85. Two trials of the effects of interventions to reduce unhealthy alcohol use in adolescents (n = 588) found mixed results: one reported a benefit in high-risk but not moderate-risk drinkers, and the other reported a statistically significant reduction in drinking frequency for boys but not girls; neither reported health or related outcomes. Across all populations (68 studies [n = 36 528]), counseling interventions were associated with a decrease in drinks per week (weighted mean difference, -1.6 [95% CI, -2.2 to -1.0]; 32 studies [37 effects; n = 15 974]), the proportion exceeding recommended drinking limits (odds ratio [OR], 0.60 [95% CI, 0.53 to 0.67]; 15 studies [16 effects; n = 9760]), and the proportion reporting a heavy use episode (OR, 0.67 [95% CI, 0.58 to 0.77]; 12 studies [14 effects; n = 8108]), and an increase in the proportion of pregnant women reporting abstinence (OR, 2.26 [95% CI, 1.43 to 3.56]; 5 studies [n = 796]) after 6 to 12 months. Health outcomes were sparsely reported and generally did not demonstrate group differences in effect. There was no evidence that these interventions could be harmful.

CONCLUSIONS AND RELEVANCE

Among adults, screening instruments feasible for use in primary care are available that can effectively identify people with unhealthy alcohol use, and counseling interventions in those who screen positive are associated with reductions in unhealthy alcohol use. There was no evidence that these interventions have unintended harmful effects.

Pharmacotherapy in dual diagnosis

The prevalence of coexisting substance misuse and psychiatric disorder (dual diagnosis, comorbidity) has increased over the past decade, and the indications are that it will continue to rise. There have simultaneously been unprecedented developments in the pharmacological treatment of alcohol, opiate and nicotine misuse. Here we evaluate the evidence on the use of some of these treatments in dual diagnosis (with psychotic, mood and anxiety disorders). The evidence base is limited by the exclusion of mental illness when pharmacological agents for substance misuse are evaluated and vice versa. We set the available information within the context of the psychosocial management of comorbid substance misuse and mental illness, and the framework for service delivery recommended by UK national policy.

Harm reduction-a systematic review on effects of alcohol reduction on physical and mental symptoms

Based on the knowledge that alcohol misuse causes a multitude of diseases and increased mortality, this systematic review examines whether a reduction of the individual alcohol consumption can contribute to a minimization of health risks within a harm reduction approach. In fact, the reviewed 63 studies indicate that interventions aiming at alcohol reduction (including total abstinence as one possible therapeutic aim) indeed resulted in or were associated with positive effects in harmful, hazardous or alcohol-dependent drinkers. Major benefits were observed for reducing alcohol-associated injuries, recovery of ventricular heart function in alcoholic cardiomyopathy, blood pressure lowering, normalization of biochemical parameter, body weight reduction, histological improvement in pre-cirrhotic alcohol-related liver disease and slowed progression of an already existing alcohol-attributable liver fibrosis. Furthermore, reduced withdrawal symptoms, prevalence of psychiatric episodes and duration of in-patient hospital days, improvement of anxiety and depression symptoms, self-confidence, physical and mental quality of life, fewer alcohol-related adverse consequences as well as lower psychosocial stress levels and better social functioning can result from reduced alcohol intake. The reviewed literature demonstrated remarkable socioeconomic cost benefits in areas such as the medical health-care system or workforce productivity. Individuals with heightened vulnerability further benefit significantly from alcohol reduction (e.g. hypertension, hepatitis C, psychiatric co-morbidities, pregnancy, but also among adolescents and young adults). Concluding, the reviewed studies strongly support and emphasize the importance and benefits of early initial screening for problematic alcohol use followed by brief and other interventions in first contact medical health-care facilities to reduce alcohol intake.

Preventing Alcohol and Tobacco Exposed Pregnancies: CHOICES Plus in Primary Care

INTRODUCTION

Alcohol and tobacco use are common among U.S. women, yet if used during pregnancy these substances present significant preventable risks to prenatal and perinatal health. Because use of alcohol and tobacco often continue into the first trimester and beyond, especially among women with unintended pregnancies, effective evidence-based approaches are needed to decrease these risk behaviors. This study was designed to test the efficacy of CHOICES Plus, a preconception intervention for reducing the risk of alcohol- and tobacco-exposed pregnancies (AEPs and TEPs).

STUDY DESIGN

RCT with two intervention groups: CHOICES Plus (n=131) versus Brief Advice (n=130). Data collected April 2011 to October 2013. Data analysis finalized February 2016.

SETTING/PARTICIPANTS

Settings were 12 primary care clinics in a large Texas public healthcare system. Participants were women who were non-sterile, non-pregnant, aged 18-44 years, drinking more than three drinks per day or more than seven drinks per week, sexually active, and not using effective contraception (N=261). Forty-five percent were smokers.

INTERVENTION

Interventions were two CHOICES Plus sessions and a contraceptive visit or Brief Advice and referral to community resources.

MAIN OUTCOME MEASURES

Primary outcomes were reduced risk of AEP and TEP through 9-month follow-up.

RESULTS

In intention-to-treat analyses across 9 months, the CHOICES Plus group was more likely than the Brief Advice group to reduce risk of AEP with an incidence rate ratio of 0.620 (95% CI=0.511, 0.757) and absolute risk reduction of -0.233 (95% CI=-0.239, -0.226). CHOICES Plus group members at risk for both exposures were more likely to reduce TEP risk (incidence rate ratio, 0.597; 95% CI=0.424, 0.840 and absolute risk reduction, -0.233; 95% CI=-0.019, -0.521).

CONCLUSIONS

CHOICES Plus significantly reduced AEP and TEP risk. Addressing these commonly co-occurring risk factors in a single preconception program proved both feasible and efficacious in a low-income primary care population. Intervening with women before they become pregnant could shift the focus in clinical practice from treatment of substance-exposed pregnancies to prevention of a costly public health concern.

TRIAL REGISTRATION

This study is registered at clinicaltrials.gov NCT01032772.

The role of screening, brief intervention, and referral to treatment in the perinatal period

Substance use during pregnancy is at least as common as many of the medical conditions screened for and managed during pregnancy. While harmful and costly, it is often ignored or managed poorly. Screening, brief intervention, and referral to treatment is an evidence-based approach to manage substance use. In September 2012, the US Centers for Disease Control and Prevention convened an Expert Meeting on Perinatal Illicit Drug Abuse to help address key issues around drug use in pregnancy in the United States. This article reflects the formal conclusions of the expert panel that discussed the use of screening, brief intervention, and referral to treatment during pregnancy. Screening for substance use during pregnancy should be universal. It allows stratification of women into zones of risk given their pattern of use. Low-risk women should receive brief advice, those classified as moderate risk should receive a brief intervention, whereas those who are high risk need referral to specialty care. A brief intervention is a patient-centered form of counseling using the principles of motivational interviewing. Screening, brief intervention, and referral to treatment has the potential to reduce the burden of substance use in pregnancy and should be integrated into prenatal care.

Correlates of partner support to abstain from prenatal alcohol use: a cross-sectional survey among Dutch partners of pregnant women

Partners can play an important role, but are often ignored in interventions targeting the prevention of prenatal alcohol use. A better understanding of the correlates of partner support to abstain from prenatal alcohol use can help to make a better use of partner support. The aim of this study was to identify correlates of this support by analysing differences between partners reporting low versus high support. An online cross-sectional study among 237 Dutch partners of pregnant women was conducted. Respondents were recruited through Dutch midwifery practices in September-October 2009. Questionnaires were based on the I-Change Model. Chi-square and t-test showed that partners reporting high support were more likely to desire their partner to abstain from alcohol use and to have received advice from their pregnant spouse or midwife that abstinence was desirable. They also had stronger perceptions that the baby would experience harm from prenatal alcohol use and that harm could be more severe, and they saw more advantages and fewer disadvantages of providing support. They also reported more influence from their social environment encouraging their support, had greater self-efficacy and had a stronger intention to support their partner during the remainder of the pregnancy compared to partners reporting low support. Health professionals may improve their alcohol advice by discussing the advantages and disadvantages of support with the partner and by encouraging couples to discuss and propose solutions for the situations in which partners find it difficult not to support alcohol abstinence. By providing an insight into important correlates of partner support, this study expands the research area aiming to reduce prenatal alcohol use.

Vital Signs: Alcohol-Exposed Pregnancies--United States, 2011-2013

BACKGROUND

Alcohol is a teratogen.* Prenatal alcohol exposure is associated with a range of adverse reproductive outcomes and can cause fetal alcohol spectrum disorders (FASDs) characterized by lifelong physical, behavioral, and intellectual disabilities. FASDs are completely preventable if a woman does not drink alcohol while pregnant.

METHODS

CDC analyzed data from the 2011-2013 National Survey of Family Growth to generate U.S. prevalence estimates of risk for an alcohol-exposed pregnancy for 4,303 nonpregnant, nonsterile women aged 15-44 years, by selected demographic and behavioral factors. A woman was considered at risk for an alcohol-exposed pregnancy during the past month if she had sex with a male, drank any alcohol, and did not (and her partner did not with her) use contraception in the past month; was not sterile; and had a partner (or partners) not known to be sterile.

RESULTS

The weighted prevalence of alcohol-exposed pregnancy risk among U.S. women aged 15-44 years was 7.3%. During a 1-month period, approximately 3.3 million women in the United States were at risk for an alcohol-exposed pregnancy.

CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE

Alcohol use in pregnancy is associated with low birthweight, preterm birth, birth defects, and developmental disabilities. Women of reproductive age should be informed of the risks of alcohol use during pregnancy, and contraception should be recommended, as appropriate, for women who do not want to become pregnant. Women wanting a pregnancy should be advised to stop drinking at the same time contraception is discontinued. Health care providers should advise women not to drink at all if they are pregnant or there is any chance they might be pregnant. Alcohol misuse screening and behavioral counseling (also known as alcohol screening and brief intervention) is recommended for all adults in primary care, including reproductive-aged and pregnant women, as an evidenced-based approach to reducing alcohol consumption among persons who consume alcohol in excess of the recommended guidelines.

A realist evaluation of an antenatal programme to change drinking behaviour of pregnant women

OBJECTIVE

to use realist evaluation to describe and explain how and in what circumstances screening and alcohol brief interventions work in routine antenatal care.

DESIGN

a realist evaluation incorporating systematic reviews and qualitative data.

SETTING

NHS Lothian, which is one of the 14 Scottish health boards.

PARTICIPANTS

participants were recruited from two maternity units. In phase one, interviews were conducted with four participants responsible for policy implementation. These data were supported by two systematic reviews. In phase two, 17 pregnant women and 15 midwives participated in interviews, with a further six midwifery team leaders involved in a focus group.

FINDINGS

training and resources provided to midwives as part of the programme acted as facilitating mechanisms that improved their skills and confidence to screen and deliver alcohol brief interventions. The programme elicited positive change in attitudes to drinking in pregnancy and possibly stimulated drinking behaviour change amongst pregnant women. However, the small numbers of pregnant women being identified for alcohol brief interventions meant delivery was infrequent and resulted in the programme not working as anticipated. The findings also revealed contextual issues around midwife-pregnant woman relationship and the challenges of negotiating the timing of screening and alcohol brief interventions delivery.

CONCLUSIONS

Drinking in pregnancy is an emotive issue, therefore delivering alcohol brief interventions at the first antenatal appointment when they are more likely to achieve the most benefits poses challenges. When training midwives to screen and deliver alcohol brief interventions, special attention is needed to improve person-centred communication skills to overcome barriers associated with discussing sensitive prenatal alcohol use and enhance early identification and delivery of alcohol brief interventions at the first antenatal appointment.

Research utilisation and knowledge mobilisation in the commissioning and joint planning of public health interventions to reduce alcohol-related harms: a qualitative case design using a cocreation approach

Background

Considerable resources are spent on research to establish what works to improve the nation’s health. If the findings from this research are used, better health outcomes can follow, but we know that these findings are not always used. In public health, evidence of what works may not ‘fit’ everywhere, making it difficult to know what to do locally. Research suggests that evidence use is a social and dynamic process, not a simple application of research findings. It is unclear whether it is easier to get evidence used via a legal contracting process or within unified organisational arrangements with shared responsibilities.

Objective

To work in cocreation with research participants to investigate how research is utilised and knowledge mobilised in the commissioning and planning of public health services to reduce alcohol-related harms.

Design, setting and participants

Two in-depth, largely qualitative, cross-comparison case studies were undertaken to compare real-time research utilisation in commissioning across a purchaser–provider split (England) and in joint planning under unified organisational arrangements (Scotland) to reduce alcohol-related harms. Using an overarching realist approach and working in cocreation, case study partners (stakeholders in the process) picked the topic and helped to interpret the findings. In Scotland, the topic picked was licensing; in England, it was reducing maternal alcohol consumption.

Methods

Sixty-nine interviews, two focus groups, 14 observations of decision-making meetings, two local feedback workshops (n = 23 andn = 15) and one national workshop (n = 10) were undertaken. A questionnaire (n = 73) using a Behaviourally Anchored Rating Scale was issued to test the transferability of the 10 main findings. Given the small numbers, care must be taken in interpreting the findings.

Findings

Not all practitioners have the time, skills or interest to work in cocreation, but when there was collaboration, much was learned. Evidence included professional and tacit knowledge, and anecdotes, as well as findings from rigorous research designs. It was difficult to identify evidence in use and decisions were sometimes progressed in informal ways and in places we did not get to see. There are few formal evidence entry points. Evidence (prevalence and trends in public health issues) enters the process and is embedded in strategic documents to set priorities, but local data were collected in both sites to provide actionable messages (sometimes replicating the evidence base).

Conclusions

Two mid-range theories explain the findings. If evidence hassaliency(relates to ‘here and now’ as opposed to ‘there and then’) andimmediacy(short, presented verbally or visually and with emotional appeal) it is more likely to be used in both settings. A second mid-range theory explains how differing tensions pull and compete as feasible and acceptable local solutions are pursued across stakeholders. Answering what works depends on answering for whom and where simultaneously to find workable (if temporary) ‘blends’. Gaining this agreement across stakeholders appeared more difficult across the purchaser–provider split, because opportunities to interact were curtailed; however, more research is needed.

Screening and Brief Interventions for Alcohol and Other Drug Use Among Pregnant Women Attending Midwife Obstetric Units in Cape Town, South Africa: A Qualitative Study of the Views of Health Care Professionals

INTRODUCTION

Despite the negative consequences of alcohol and other drug use during pregnancy, few interventions for pregnant women are implemented, and little is known about their feasibility and acceptability in primary health care settings in South Africa. As part of the formative phase of screening, brief intervention, and referral to treatment for substance use among women presenting for antenatal care, the present study explored health care workers' attitudes and perceptions about screening, brief intervention, and referral to treatment among this population.

METHODS

Forty-three health care providers at 2 public sector midwife obstetric units in Cape Town, South Africa, were interviewed using an open-ended, semistructured interview schedule designed to identify factors that hinder or support the implementation of screening, brief intervention, and referral to treatment for substance use in these settings. Transcribed interviews were analyzed using the framework approach.

RESULTS

Health care providers agreed that there is a substantial need for screening, brief intervention, and referral to treatment for substance use among pregnant women and believe such services potentially could be integrated into routine care. Several women-, staff-, and clinic-level barriers were identified that could hinder the successful implementation in antenatal services. These barriers included the nondisclosure of alcohol and other drug use, the intervention being considered as an add-on service or additional work, negative staff attitudes toward implementation of an intervention, poor staff communication styles such as berating women for their behavior, lack of interest from staff, time constraints, staff shortages, overburdened workloads, and language barriers.

DISCUSSION

The utility of screening, brief intervention, and referral to treatment for addressing substance use among pregnant women in public health midwife obstetric units was supported, but consideration will need to be given to addressing a variety of barriers that have been identified.

Reducing alcohol use during pregnancy via health counseling by midwives and internet-based computer-tailored feedback: a cluster randomized trial

Background

Effective interventions are needed to reduce neurobehavioral impairments in children due to maternal alcohol use during pregnancy. Currently, health-counseling interventions have shown inconsistent results to reduce prenatal alcohol use. Thus, more research using health counseling is needed to gain more knowledge about the effectiveness of this type of intervention on reducing alcohol use during pregnancy. An alternative and promising strategy is computer tailoring. However, to date, no study has shown the effectiveness of this intervention mode.

Objective

The aim was to test the effectiveness of health counseling and computer tailoring on stopping and reducing maternal alcohol use during pregnancy in a Dutch sample of pregnant women using alcohol.

Methods

A total of 60 Dutch midwifery practices, randomly assigned to 1 of 3 conditions, recruited 135 health counseling, 116 computer tailoring, and 142 usual care respondents from February to September 2011. Health-counseling respondents received counseling from their midwife according to a health-counseling protocol, which consisted of 7 steps addressed in 3 feedback sessions. Computer-tailoring respondents received usual care from their midwife and 3 computer-tailored feedback letters via the Internet. Usual care respondents received routine alcohol care from their midwife. After 3 and 6 months, we assessed the effect of the interventions on alcohol use.

Results

Multilevel multiple logistic regression analyses showed that computer-tailoring respondents stopped using alcohol more often compared to usual care respondents 6 months after baseline (53/68, 78% vs 51/93, 55%; P=.04). Multilevel multiple linear regression analyses showed that computer-tailoring respondents (mean 0.35, SD 0.31 units per week) with average (P=.007) or lower (P<.001) alcohol use before pregnancy or with average (P=.03) or lower (P=.002) social support more strongly reduced their alcohol use 6 months after baseline compared to usual care respondents (mean 0.48, SD 0.54 units per week). Six months after baseline, 72% (62/86) of the health-counseling respondents had stopped using alcohol. This 17% difference with the usual care group was not significant.

Conclusions

This is the first study showing that computer tailoring can be effective to reduce alcohol use during pregnancy; health counseling did not effectively reduce alcohol use. Future researchers developing a health-counseling intervention to reduce alcohol use during pregnancy are recommended to invest more in recruitment of pregnant women and implementation by health care providers. Because pregnant women are reluctant to disclose their alcohol use to health professionals and computer tailoring preserves a person’s anonymity, this effective computer-tailoring intervention is recommended as an attractive intervention for pregnant women using alcohol.

The effectiveness of a brief intervention to reduce alcohol consumption in pregnancy: a controlled trial

OBJECTIVES

Alcohol consumption during pregnancy potentially has significant effects on both mother and baby. The aim of the study was to determine the effectiveness of a brief intervention to reduce alcohol consumption during pregnancy.

METHODS

This study was performed at the outpatient antenatal clinics of a large academic maternity teaching hospital in Dublin city centre. Six hundred and fifty-six women who drank alcohol before pregnancy were recruited at their first antenatal clinic visit. Drinking patterns before pregnancy, since becoming pregnant, and in later pregnancy (at ~32 weeks of gestation) were assessed using the Alcohol Use Disorders Identification Test (AUDIT). A controlled study was conducted - participants were allocated to either the brief intervention group (screening and 5 minutes of non-directive discussion of their drinking pattern) or a control group (screening and treatment as usual).

RESULTS

Before pregnancy, 57% of women consumed five or more units of alcohol per drinking occasion (i.e. binge drinking); during pregnancy, the rate of binge drinking fell to 4.8%. Sixty per cent of women who drank before pregnancy ceased drinking when pregnant, and a further 9% reduced their intake substantially. Four hundred and ninety-nine women were followed up in later pregnancy. The brief intervention did not produce any significant reduction in alcohol consumption above that attributable to pregnancy and comprehensive screening in antenatal care. Larger reductions in alcohol intake during pregnancy were associated with younger age, non-Irish nationality and greater intake of alcohol before first antenatal clinic visit.

CONCLUSION

Pregnancy itself produces abstinence and large reductions in alcohol consumption, even among women who drink relatively heavily. Consequently, a universal screening and brief intervention programme is not warranted but screening and targeted interventions could be appropriate such as repeated interventions for those who continue to binge drink. Future research could include evaluating interventions for those women who continue to binge drink during pregnancy and exploring ways of maintaining reductions in alcohol consumption among women who decreased consumption during pregnancy.

Alcohol brief interventions in Scottish antenatal care: a qualitative study of midwives' attitudes and practices

BACKGROUND

Infants exposed to alcohol in the womb are at increased risk of experiencing health problems. However, mixed messages about the consequences of prenatal alcohol consumption have resulted in inconsistent attitudes and practices amongst some healthcare practitioners. Screening and alcohol brief interventions (ABIs) can reduce risky drinking in various clinical settings. Recently, a program of screening and ABIs have been implemented in antenatal care settings in Scotland. However, current evidence suggests that midwives' involvement in alcohol brief interventions activities is patchy. This study explored midwives' attitudes and practices regarding alcohol screening and ABIs in order to understand why they are relatively underutilized in antenatal care settings compared to other clinical settings.

METHODS

This was a qualitative study, involving semi-structured interviews with 15 midwives and a focus group with a further six midwifery team leaders (21 participants in total) in Scotland. Interview transcripts were analysed using thematic analysis.

RESULTS

Midwives were positive about their involvement in the screening and ABI program. However, they were not completely convinced about the purpose and value of the screening and ABIs in antenatal care. In the midst of competing priorities, the program was seen as having a low priority in their workload. Midwives felt that the rapport between them and pregnant women was not sufficiently established at the first antenatal appointment to allow them to discuss alcohol issues appropriately. They reported that many women had already given up drinking or were drinking minimal amounts prior to the first antenatal appointment.

CONCLUSIONS

Midwives recognised the important role they could play in alcohol intervention activities in antenatal care. As the majority of women stop consuming alcohol in pregnancy, many will not need an ABI. Those who have not stopped are likely to need an ABI, but midwives were concerned that it was this group that they were most likely to alienate by discussing such concerns. Further consideration should be given to pre-pregnancy preventative measures as they are more likely to reduce alcohol-exposed pregnancies.

Alcohol and Other Drug Use during Pregnancy among Women Attending Midwife Obstetric Units in the Cape Metropole, South Africa

Little is known about the nature and extent of alcohol and other drug (AOD) use among pregnant women in Cape Town, South Africa, despite the very high levels of AOD use in this part of the country. A cross-sectional survey was conducted among pregnant women attending 11 Midwife Obstetric Units (MOUs) in greater Cape Town. A two-stage cluster survey design was used. In total, 5231 pregnant women were screened to assess self-reported prevalence estimates. Of these, 684 (13.1%) were intentionally subsampled and completed an interviewer-administered questionnaire and provided a urine sample for biological screening. Urinalyses showed that 8.8% (95% CI: 6.7–10.9) of the subsample tested positive for at least one illicit drug. This is higher than the self-reported prevalence (3.6%). In addition, 19.6% (95% CI: 16.3–22.8) of the sub-sample tested positive for alcohol which is lower than the self-reported prevalence (36.9%). There are high levels of substance use among pregnant women attending public sector antenatal clinics. There is a need for routine screening for AOD use and appropriate responses depending on the women's level of risk.

Substance use among women veterans: epidemiology to evidence-based treatment

An increasing percentage of women are U.S. Military Veterans. We review the substance misuse rates and comorbidities and the risk factors for and consequences of substance use among women Veterans. Women Veterans may have higher rates of substance misuse and comorbid psychiatric and medical disorders than male Veterans and women who are not Veterans. Studies support the AUDIT-C as a scaled marker of alcohol-related risk among female Veterans, but validated drug screening instruments are needed. We discuss evidence-based approaches in terms of treating women Veterans' substance misuse in primary and specialty care settings, along with knowledge gaps and potential research priorities to improve care in this special population.

Brief motivational enhancement intervention to prevent or reduce postpartum alcohol use: a single-blinded, randomized controlled effectiveness trial

AIMS

The aim of this study is to assess the effect of brief motivational enhancement intervention postpartum alcohol use.

DESIGN

This study is a single-blinded, randomized controlled effectiveness trial in which pregnant women were assigned to receive usual care or up to 5 face-to-face brief motivational enhancement sessions lasting 10-30 minutes each and occurring at study enrollment, 4 and 8 weeks after enrollment, 32 weeks of gestation, and 6 weeks postpartum.

SETTING

The setting is in a large, urban, obstetrics clinic.

PARTICIPANTS

Participants were women who were ≥ 18 years old, <20 weeks of gestation, and consumed alcohol during pregnancy. Of 3438 women screened, 330 eligible women were assigned to usual care (n = 165) or intervention (n=165). Due to missing data, we analyzed 125 in the intervention group and 126 in the usual care group.

MEASUREMENTS

The measurements were the proportion of women with any alcohol use and the number of drinks per day, reported via follow-up telephone interviews at 4 and 8 weeks after enrollment, 32 weeks of gestation, and 6 weeks, 6 months, and 12 months postpartum.

FINDINGS

In random effects models adjusted for confounders, the intervention group was less likely to use any alcohol (odds ratio 0.50; 95% confidence interval [CI], 0.23-1.09; P=0.08) and consumed fewer drinks per day (coefficient -0.11; 95% CI -0.23-0.01; P=0.07) than, the usual care group in the postpartum period but these differences were non-significant. Missing data during the prenatal period prevented us from modeling prenatal alcohol use.

CONCLUSIONS

Brief motivational enhancement intervention delivered in an obstetrical outpatient setting did not conclusively decrease alcohol use during the postpartum period.

The treatment of alcohol and opioid dependence in pregnant women

PURPOSE OF REVIEW

This article addresses the question of 'best treatment options', which clinicians face when treating pregnant women with alcohol and opioid dependence.

RECENT FINDINGS

Studies show that alcohol consumption is associated with fetal abnormalities and long-term cognitive problems depending on the amount consumed, drinking pattern, and time of gestation. Screening and evaluation of specific interventions are important to reduce alcohol consumption during pregnancy and associated problems in infants. Opioid detoxification is only recommended beyond the first trimester and only in those pregnant women who refuse opioid maintenance therapy. Methadone is the most established treatment of pregnant opioid-dependent women, though recent results indicate some advantages of buprenorphine, slow-release oral methadone and diamorphine compared with methadone.

SUMMARY

Benzodiazepines seem to be the most recommendable option for managing alcohol withdrawal, and psychosocial interventions succeed in reducing alcohol consumption or in maintaining abstinence in alcohol-dependent pregnant women. Regarding opioid dependence, current results suggest that factors like the health status of the mother, the need for additional medications (e.g. treatment for HIV), comorbid drug dependence, and concurrent drug use need to be considered in order to find the 'best opioid substitute'.

Brief intervention to reduce risky drinking in pregnancy: study protocol for a randomized controlled trial

Background

Risky drinking in pregnancy by UK women is likely to result in many alcohol-exposed pregnancies. Studies from the USA suggest that brief intervention has promise for alcohol risk reduction in antenatal care. However, further research is needed to establish whether this evidence from the USA is applicable to the UK. This pilot study aims to investigate whether pregnant women can be recruited and retained in a randomized controlled trial of brief intervention aimed at reducing risky drinking in women receiving antenatal care.

Methods

The trial will rehearse the parallel-group, non-blinded design and procedures of a subsequent definitive trial. Over 8 months, women aged 18 years and over (target number 2,742) attending their booking appointment with a community midwife (n = 31) in north-east England will be screened for alcohol consumption using the consumption questions of the Alcohol Use Disorders Identification Test (AUDIT-C). Those screening positive, without a history of substance use or alcohol dependence, with no pregnancy complication, and able to give informed consent, will be invited to participate in the trial (target number 120). Midwives will be randomized in a 1:1 ratio to deliver either treatment as usual (control) or structured brief advice and referral for a 20-minute motivational interviewing session with an alcohol health worker (intervention). As well as demographic and health information, baseline measures will include two 7-day time line follow-back questionnaires and the EuroQoL EQ-5D-3 L questionnaire. Measures will be repeated in telephone follow-ups in the third trimester and at 6 months post-partum, when a questionnaire on use of National Health Service and social care resources will also be completed. Information on pregnancy outcomes and stillbirths will be accessed from central health service records before the follow-ups. Primary outcomes will be rates of eligibility, recruitment, intervention delivery, and retention in the study population, to inform power calculations for a definitive trial. The health-economics component will establish how cost-effectiveness will be assessed, and examine which data on health service resource use should be collected in a main trial. Participants’ views on instruments and procedures will be sought to confirm their acceptability.

Discussion

The study will produce a full trial protocol with robust sample-size calculations to extend evidence on effectiveness of screening and brief intervention.

Motivational enhancement therapy coupled with cognitive behavioral therapy versus brief advice: a randomized trial for treatment of hazardous substance use in pregnancy and after delivery

OBJECTIVE

The objective was to compare the efficacy of motivational enhancement therapy coupled with cognitive behavioral therapy (MET-CBT) to brief advice for treatment of substance use in pregnancy.

METHOD

This was a randomized, parallel, controlled trial that was yoked to prenatal care and delivered at hospital outpatient clinics. We enrolled 168 substance-using women who had not yet completed an estimated 28 weeks of pregnancy. Obstetrical clinicians provided brief advice, and study nurses administered manualized MET-CBT. The primary outcome was percentage of days in the prior 28 days in which alcohol and/or drugs were used immediately before and 3 months postdelivery.

RESULTS

There were no significant differences across groups in terms of self-reported percentage of days in which drugs or alcohol were used prior to and 3 months postdelivery. Biological measures showed similar results. There was a trend (P=.08) for lower risk of preterm birth among those who received MET-CBT.

CONCLUSIONS

The tested interventions had similar therapeutic effects. Hence, both treatments may be suitable for pregnant substance users, depending on the population, setting and provider availability. Interventions that are intensified after delivery may decrease postpartum "rebound" effects in substance misuse.

The effectiveness of a community-based intervention program for women at-risk for giving birth to a child with Fetal Alcohol Spectrum Disorder (FASD)

The goal of this study was to determine whether the First Steps program (modeled after the Parent-Child Assistance Program) resulted in improved outcomes among women at-risk for giving birth to a child with FASD. We conducted a retrospective analysis of data on 70 participants in the First Steps program. Clients were high risk and faced many life challenges, including: being on welfare, substance abuse, physical and sexual abuse as children, mental health issues, criminal activity, and unplanned pregnancies. We found a significant increase in birth control use and decrease in welfare rates from pre- to post-program. At program exit, many participants were abstinent from alcohol and/or drugs and the majority did not experience a subsequent pregnancy. Clients also showed significant increases in goals and decreases in needs from pre-to post-program. The First Steps program demonstrated promising outcomes for women at-risk for giving birth to a child with FASD.

Home visits during pregnancy and after birth for women with an alcohol or drug problem

BACKGROUND

One potential method of improving outcome for pregnant or postpartum women with a drug or alcohol problem is with home visits.

OBJECTIVES

To determine the effects of home visits during pregnancy and/or after birth for women with a drug or alcohol problem.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2011), CENTRAL (The Cochrane Library 2011, Issue 4 of 4), MEDLINE (1966 to 30 November 2011), EMBASE (1980 to 30 November 2011), CINAHL (1982 to 30 November 2011) and PsycINFO (1974 to 30 November 2011) supplemented by searches of citations from previous reviews and trials and contact with experts.

SELECTION CRITERIA

Studies using random or quasi-random allocation of pregnant or postpartum women with a drug or alcohol problem to home visits. Trials enrolling high-risk women of whom more than 50% were reported to use drugs or alcohol were also eligible.

DATA COLLECTION AND ANALYSIS

Review authors performed assessments of trials independently. We performed statistical analyses using fixed-effect and random-effects models where appropriate.

MAIN RESULTS

Seven studies (reporting 803 mother-infant pairs) compared home visits mostly after birth with no home visits. Visitors included community health nurses, paediatric nurses, trained counsellors, paraprofessional advocates, midwives and lay African-American women. Several studies had significant methodological limitations. There was no significant difference in continued illicit drug use (three studies, 384 women; risk ratio (RR) 1.05, 95% confidence interval (CI) 0.89 to 1.24), continued alcohol use (three studies, 379 women; RR 1.18, 95% CI 0.96 to 1.46), failure to enrol in a drug treatment program (two studies, 211 women; RR 0.45, 95% CI 0.10 to 1.94), not breastfeeding at six months (two studies, 260 infants; RR 0.95, 95% CI 0.83 to 1.10), incomplete six-month infant vaccination schedule (two studies, 260 infants; RR 1.09, 95% CI 0.91 to 1.32), the Bayley Mental Development Index (three studies, 199 infants; mean difference 2.89, 95% CI -1.17 to 6.95) or Psychomotor Index (MD 3.14, 95% CI -0.03 to 6.32), child behavioural problems (RR 0.46, 95% CI 0.21 to 1.01), infants not in care of biological mother (two studies, 254 infants; RR 0.83, 95% CI 0.50 to 1.39), non-accidental injury and non-voluntary foster care (two studies, 254 infants; RR 0.16, 95% CI 0.02 to 1.23) or infant death (three studies, 288 infants; RR 0.70, 95% CI 0.12 to 4.16). Individual studies reported a significant reduction in involvement with child protective services (RR 0.38, 95% CI 0.20 to 0.74) and failure to use postpartum contraception (RR 0.41, 95% CI 0.20 to 0.82).

AUTHORS' CONCLUSIONS

There is insufficient evidence to recommend the routine use of home visits for pregnant or postpartum women with a drug or alcohol problem. Further large, high-quality trials are needed.

Universal screening for alcohol and drug use and racial disparities in child protective services reporting

This study examines racial disparities in Child Protective Services (CPS) reporting at delivery in a county with universal screening for alcohol/drug use in prenatal care. It also explores two mechanisms through which universal screening could reduce reporting disparities: Equitable Surveillance and Effective Treatment. Equitable Surveillance is premised on the assumptions that identification of drug use through screening in prenatal care leads to CPS reporting at delivery and that Black women are screened more than White women, which leads to disproportionate reporting of Black newborns. Universal screening would correct this by ensuring that prenatal providers screen and therefore also report White women to CPS, thereby reducing disparities. Effective Treatment is premised on the idea that identification of drug use through screening in prenatal care leads women to receive treatment during pregnancy, which thereby reduces CPS reporting at delivery. Universal screening would lead to prenatal providers screening more Black women and thereby to more Black women receiving treatment prenatally. The increase in treatment receipt during pregnancy would then decrease the number of Black newborns reported to CPS at delivery, thereby reducing disparities. County data were used to compare the racial/ethnic distribution of women and newborns in three points in the system (identification in prenatal care, treatment entry during pregnancy, and reporting to CPS at delivery related to maternal alcohol/drug use) and explore pathways to treatment. Despite Black women having alcohol/drug use identified by prenatal care providers at similar rates to White women and entering treatment more than expected, Black newborns were four times more likely than White newborns to be reported to CPS at delivery. This contradicts the premise of Effective Treatment. By default, findings were more consistent with Equitable Surveillance than Effective Treatment. Providers and policy makers should not assume that universal screening in prenatal care reduces CPS reporting disparities.

Universal alcohol/drug screening in prenatal care: a strategy for reducing racial disparities? Questioning the assumptions

Agencies and organizations promoting universal screening for alcohol and drug use in prenatal care argue that universal screening will reduce White versus Black racial disparities in reporting to Child Protective Services (CPS) at delivery. Yet, no published research has assessed the impact of universal screening on reporting disparities or explored plausible mechanisms. This review defines two potential mechanisms: Equitable Surveillance and Effective Treatment and identifies assumptions underlying each mechanism. It reviews published literature relating to each assumption. Research relating to assumptions underlying each mechanism is primarily inconclusive or contradictory. Thus, available research does not support the claim that universal screening for alcohol and drug use in prenatal care reduces racial disparities in CPS reporting at delivery. Reducing these reporting disparities requires more than universal screening.

A randomized phase I trial of a brief computer-delivered intervention for alcohol use during pregnancy

BACKGROUND

Drinking alcohol during pregnancy has a range of negative consequences for the developing fetus. Screening and brief intervention approaches have significant promise, but their population impact may be limited by a range of challenges to implementation. We, therefore, conducted preliminary acceptability and feasibility evaluation of a computer-delivered brief intervention for alcohol use during pregnancy.

METHODS

Participants were 50 pregnant women who screened positive for risky drinking during a routine prenatal clinic visit and were randomly assigned to computer-delivered brief intervention or assessment-only conditions.

RESULTS

Ratings of intervention ease of use, helpfulness, and other factors were high (4.7-5.0 on a 1-5 scale). Participants in both conditions significantly decreased alcohol use at follow-up, with no group differences; however, birth weights for infants born to women in the intervention group were significantly higher (p<0.05, d = 0.62).

CONCLUSIONS

Further development and study of computer-delivered screening and intervention for alcohol use during pregnancy are warranted.

A Web-Based Intervention to Reduce Alcohol-Exposed Pregnancies in the Community

Despite warnings that drinking during pregnancy is unsafe, many women are still at risk for an alcohol-exposed pregnancy (AEP). This article describes the outcomes of a web-based, self-guided change intervention designed to lower the risk for AEPs in a community. A sample of 458 women, between the ages of 18 and 44 years and at risk for an AEP (i.e., any drinking in the past 30 days and not using reliable contraception), participated in the study. A total of 58% of the women enrolled in the self-guided change intervention were no longer at risk for an AEP at the 4-month follow-up. Sublevel analysis revealed that mail and online versions of the intervention were equally successful at reducing risk for an AEP. This study represents a successful implementation of a web-based, self-guided change intervention to reduce risk for an AEP, an intervention with community-wide reach due to the Internet platform.

Neurocriminology

In the past several decades there has been an explosion of research into the biological correlates to antisocial behavior. This chapter reviews the state of current research on the topic, including a review of the genetics, neuroimaging, neuropsychological, and electrophysiological studies in delinquent and antisocial populations. Special attention is paid to the biopsychosocial model and gene-environment interactions in producing antisocial behavior.

Health professionals addressing alcohol use with pregnant women in Western Australia: barriers and strategies for communication

Health professionals have an important role to play in preventing prenatal alcohol exposure. In 2006 qualitative data were collected from 53 health professionals working in primary care in metropolitan and regional Western Australia. Thematic analysis was used to elucidate barriers in addressing prenatal alcohol use and the strategies used to overcome them. Health professionals identified strategies for obtaining alcohol use information from pregnant women but they are not recognizing moderate alcohol intake in pregnant women. Study limitations are noted and the implications of the results are discussed. This research was funded by the Health Promotion Foundation of Western Australia.

Brief alcohol intervention to prevent drinking during pregnancy: an overview of research findings

PURPOSE OF REVIEW

The aim is to describe the theory and practice of brief alcohol interventions and provide a summary of the current evidence base, including details about the four randomized controlled trials that have been conducted with pregnant women. Opportunities for providing alcohol interventions for pregnant women in antenatal care are also addressed.

RECENT FINDINGS

Brief intervention has emerged as a promising approach to provide early intervention, before or soon after the onset of alcohol-related problems. There is convincing evidence for the efficacy and effectiveness of brief intervention in various healthcare settings. The findings from four randomized brief intervention trials that have been conducted with pregnant women are consistent with the broader literature on brief intervention. The interventions were effective in reducing alcohol consumption, but control group participants also reduced their consumption to the degree that statistically significant differences between the groups were difficult to detect.

SUMMARY

Pregnant women are generally believed to be highly motivated to reduce their alcohol intake, and the contextual change provided by the pregnancy provides an opportunity to break habitual drinking behaviour. There is an empirical and theoretical support for providing brief intervention in antenatal care to achieve reduced or no alcohol consumption during pregnancy.

Brief screening questionnaires to identify problem drinking during pregnancy: a systematic review

AIMS

Although prenatal screening for problem drinking during pregnancy has been recommended, guidance on screening instruments is lacking. We investigated the sensitivity, specificity and predictive value of brief alcohol screening questionnaires to identify problem drinking in pregnant women.

METHODS

Electronic databases from their inception to June 2008 were searched, as well as reference lists of eligible papers and related review papers. We sought cohort or cross-sectional studies that compared one or more brief alcohol screening questionnaire(s) with reference criteria obtained using structured interviews to detect 'at-risk' drinking, alcohol abuse or dependency in pregnant women receiving prenatal care.

RESULTS

Five studies (6724 participants) were included. In total, seven instruments were evaluated: TWEAK (Tolerance, Worried, Eye-opener, Amnesia, Kut down), T-ACE [Take (number of drinks), Annoyed, Cut down, Eye-opener], CAGE (Cut down, Annoyed, Guilt, Eye-opener], NET (Normal drinker, Eye-opener, Tolerance), AUDIT (Alcohol Use Disorder Identification Test), AUDIT-C (AUDIT-consumption) and SMAST (Short Michigan Alcohol Screening Test). Study quality was generally good, but lack of blinding was a common weakness. For risk drinking sensitivity was highest for T-ACE (69-88%), TWEAK (71-91%) and AUDIT-C (95%), with high specificity (71-89%, 73-83% and 85%, respectively). CAGE and SMAST performed poorly. Sensitivity of AUDIT-C at score >or=3 was high for past year alcohol dependence (100%) or alcohol use disorder (96%) with moderate specificity (71% each). For life-time alcohol dependency the AUDIT at score >or=8 performed poorly.

CONCLUSION

T-ACE, TWEAK and AUDIT-C show promise for screening for risk drinking, and AUDIT-C may also be useful for identifying alcohol dependency or abuse. However, their performance as stand-alone tools is uncertain, and further evaluation of questionnaires for prenatal alcohol use is warranted.

Prevention of fetal alcohol spectrum disorders

Alcohol use among women of childbearing age is a leading, preventable cause of birth defects and developmental disabilities in the United States. Although most women reduce their alcohol use upon pregnancy recognition, some women report drinking during pregnancy and others may continue to drink prior to realizing they are pregnant. These findings emphasize the need for effective prevention strategies for both pregnant and nonpregnant women who might be at risk for an alcohol-exposed pregnancy (AEP). This report reviews evidence supporting alcohol screening and brief intervention as an effective approach to reducing problem drinking and AEPs that can lead to fetal alcohol spectrum disorders. In addition, this article highlights a recent report of the National Task Force on Fetal Alcohol Syndrome and Fetal Alcohol Effect that describes effective interventions to reduce alcohol use and AEPs, and outlines recommendations on promoting and improving these strategies. Utilizing evidence-based alcohol screening tools and brief counseling for women at risk for an AEP and other effective population-based strategies can help achieve future alcohol-free pregnancies.

Do Canadian prenatal record forms integrate evidence-based guidelines for the diagnosis of a FASD?

OBJECTIVES

Prenatal alcohol exposure is a significant public health issue with lifelong psychological, emotional and financial costs associated with caring for an affected individual. In 2005, the Public Health Agency of Canada and Health Canada's First Nations and Inuit Health Branch developed evidence-based guidelines for the diagnosis of a Fetal Alcohol Spectrum Disorder (FASD). We examined the extent to which prenatal records across Canadian provinces and territories currently integrate key recommendations from these guidelines.

METHODS

A content analysis of prenatal record forms retrieved from each Canadian province and territory (N = 12) was conducted to identify all questions or intervention prompts related to prenatal screening, exposure assessment, counseling or referral for maternal alcohol use during pregnancy. Findings were reviewed in relation to recommendations extrapolated from the Canadian guidelines and the FASD literature.

RESULTS

All the prenatal record forms contained questions to assess maternal alcohol use during pregnancy. However, the dimensions of alcohol consumption assessed and the format, wording and number of items related to each dimension varied markedly across provinces/territories. Only five prenatal record forms included a validated screening tool to identify risky alcohol drinking behaviour. Most of the forms lacked prompts to encourage providers to intervene or refer pregnant clients with high-risk drinking behaviour.

CONCLUSION

Integration of the Canadian recommendations into Canadian prenatal record forms may be an effective public health strategy for helping identify pregnancies at high risk for alcohol exposure, reducing the incidence of a FASD through appropriate prenatal intervention and referral, and facilitating early diagnosis of a FASD.
