Screening for substance use in pregnancy and the newborn

Implementation of universal screening for substance use in pregnancy in a public healthcare system

Objective

Screening questionnaires are one option for identification of at-risk substance use and substance use disorder (SUD) during pregnancy. We report the experience of a single institution following universal implementation of a brief screening tool for self-reported substance use at the first prenatal encounter.

Study Design

This is a prospective implementation study evaluating screening for substance use in pregnancy in a large safety net healthcare system. Universal screening with the National Institute of Drug Abuse (NIDA) Quick Screen V1.0 was integrated into the electronic medical record (EMR) and administered at the first point of contact with the healthcare system. SUD was identified initially with diagnosis within the EMR by a healthcare provider and was confirmed with toxicology (maternal or neonatal) results corroborating a pattern of substance use and maternal and neonatal ICD-10 codes for SUD. Patients identified with SUD were then classified as moderate or severe SUD based on criteria established by the Diagnostic and Statistical Manual of Mental Disorders, 5th edition. We measured rates of NIDA implementation across different healthcare settings, evaluated NIDA concordance with ascertainment of SUD, and compared adverse pregnancy outcomes associated with moderate and severe SUD.

Results

From July 28, 2021, through June 25, 2022, 14,634 unique pregnant individuals accessed care at ambulatory and acute care sites. Universal implementation of the NIDA Quick Screen identified at-risk substance use in 2146 (14.7%) of those who accessed our system, or 17.1% of 12,550 screened across the system, with greater screen completion in ambulatory over acute care settings. SUD was identified in 256 (1.7%) of 14,634 individuals and moderate or severe SUD was identified in 184 (1.3%). Among those with moderate or severe SUD, 90 (48.9%) were NIDA positive, 22 (12.0%) NIDA negative, and 72 (39.1%) unscreened. Of 94 individuals with NIDA discordance or who were unscreened 76 (81%) accessed initial care through an acute care setting. Of 96 individuals with opioid use disorder, 68 (70.8%) were treated with medication-assisted therapy, and 56 (58.3%) were screened with the NIDA Quick Screen. Among delivered individuals with available outcomes, those with moderate or severe SUD were less likely to seek prenatal care (71 (76%) vs 9852 (98%), <0.001)) and more likely to deliver before 37 weeks, (18 (20%) vs 909 (9%), RR (95% CI) 2.13 (1.40, 3.24)) compared to individuals without SUD. Neonates exposed to moderate or severe SUD were more likely to have birth weight <10th centile for gestational age (20 (22%) vs 1147 (12%), RR (95% CI) 1.92 (1.29, 2.85)) and require admission to the neonatal intensive care unit (NICU) (19 (21%) vs 964 (10%), RR (95%) 1.95 (1.30, 2.93)).

Conclusion

Universal screening was implemented across a large public healthcare system at a high rate, with higher rates of implementation in ambulatory settings. NIDA successfully identified at-risk substance use in 17% of the SUD cohort but failed to identify more than 50% of patients with moderate or severe SUD. Patients with moderate and severe SUD accessed care primarily through the emergency department and experienced higher rates of adverse obstetric and neonatal outcomes. Future efforts to identify, engage, and retain this highest-risk group are needed.

In our responses to the overdose epidemic, we cannot forget pregnant and postpartum people

In 2021, there were over 100,000 drug overdose deaths in the United States (US). Death rates have increased faster among women than men, particularly among Black and Indigenous people. Although drug overdose is a leading cause of pregnancy-associated deaths, birthing people are rarely emphasized in discussions of overdose and research and services remain limited. Data show increases in drug use and deaths among women of child-bearing age, with risks continuing in the postpartum period. Harms experienced by birthing people who use drugs occur in the context of broader inequities in maternal morbidity and mortality that lead to disparate reproductive health outcomes. Shared structural antecedents (e.g. intersecting sexism and racism, stigma, and punitive policies) underlie overlapping epidemics of overdose and maternal morbidity and mortality. Here we discuss the unique challenges placed on birthing people who use drugs and make recommendations on how to mitigate harms by improving access to and delivery of quality care and addressing unjust policies and practices. We highlight the need for integrated health services, clearer guidelines rooted in equity, and the need for changes to policy and practice that support rather than punish. To better serve individuals and families impacted by substance use, we need multilevel solutions that advance gender equity and racial justice to reshape and/or dismantle the systems that undergird oppression.

Substance Use Disorders in Women

Substance use disorder (SUD) is among the leading causes of premature morbidity and mortality and imposes significant health, economic, and social burdens. Gender differences have been found in the development, course, and treatment of SUD, with women at increased risk for physiologic and psychosocial consequences compared with men. Reasons for these differences are multifold and include biological, genetic, environmental, and behavioral factors. This article discusses SUD among women, emphasizing clinical considerations for care. Specific topics include epidemiology, sex and gender differences, common comorbidities, screening, diagnosis, treatment, pregnancy, and sociocultural factors.

Assessing the clinical utility of toxicology testing in the peripartum period

BACKGROUND

Toxicology testing is frequently used as a means of gathering objective data about substance use in pregnancy, but little is known about the clinical utility of testing in the peripartum setting.

OBJECTIVE

This study aimed to characterize the utility of obtaining maternal-neonatal dyad toxicology testing at the time of delivery.

STUDY DESIGN

We performed a retrospective chart review of all deliveries in a single healthcare system in Massachusetts between 2016 and 2020, and identified deliveries with either maternal or neonatal toxicology testing at delivery. An unexpected result was defined as a positive test for a nonprescribed substance that was not known on the basis of clinical history, self-report, or previous toxicology testing within a week of delivery, excluding results for cannabis. We evaluated the characteristics of maternal-infant dyads with unexpected positive results, unexpected positive results by rationale for testing, changes in clinical management after an unexpected positive test, and maternal outcomes in the year after delivery using descriptive statistics.

RESULTS

Of the 2036 maternal-infant dyads with toxicology tests performed during the study period, there were 80 (3.9%) with an unexpected positive result. Diagnosis of substance use disorder with active use in the last 2 years was the clinical rationale for testing that yielded the greatest number of unexpected positive results (10.7% of total tests ordered for this rationale). Inadequate prenatal care (5.8%), maternal use of medication for opioid use disorder (3.8%), maternal medical indications such as hypertension or placental abruption (2.3%), history of substance use disorder in remission (1.7%), or maternal cannabis use (1.6%) yielded lower rates of unexpected results compared with a recent substance use disorder (within the last 2 years). Solely on the basis of findings from unexpected test results, 42% of dyads were referred to child protective services, 30% of dyads had no documentation of maternal counseling during delivery hospitalization, and 31% did not receive breastfeeding counseling after an unexpected test; 22.8% had monitoring for neonatal opioid withdrawal syndrome. Postpartum, 26 (32.5%) were referred to substance use disorder treatment, 31 (38.8%) attended a postpartum mental health visit, and only 26 (32.5%) attended a postpartum visit. Fifteen individuals (18.8%) were readmitted in the year after delivery, all for substance-related medical complications.

CONCLUSION

Unexpected positive toxicology results at delivery were uncommon, particularly when tests were sent for frequently used clinical rationales for testing, suggesting a need to revisit guidelines surrounding appropriateness of indications for toxicology testing. The poor maternal outcomes in this cohort highlight a missed opportunity for maternal connection to counseling and treatment in the peripartum period.

Continuities in maternal substance use from early adolescence to parenthood: findings from the intergenerational cohort consortium

BACKGROUND

This study assessed the extent to which women's preconception binge drinking, tobacco use and cannabis use, reported prospectively in adolescence and young adulthood, predicted use of these substances during pregnancy and at 1 year postpartum.

METHODS

Data were pooled from two intergenerational cohort studies: the Australian Temperament Project Generation 3 Study (395 mothers, 691 pregnancies) and the Victorian Intergenerational Health Cohort Study (398 mothers, 609 pregnancies). Alcohol, tobacco and cannabis use were assessed in adolescence (13-18 years), young adulthood (19-29 years) and at ages 29-35 years for those transitioning to parenthood. Exposures were weekly or more frequent preconception binge drinking (5 + drinks in one session), tobacco use and cannabis use. Outcomes were any alcohol, tobacco and cannabis use prior to awareness of the pregnancy, after awareness of pregnancy (up to and including the third trimester pregnancy) and at 1 year postpartum.

RESULTS

Frequent preconception binge drinking, tobacco use and cannabis use across both adolescence and young adulthood were strong predictors of continued use post-conception, before and after awareness of the pregnancy and at 1 year postpartum. Substance use limited to young adulthood also predicted continued use post-conception.

CONCLUSIONS

Persistent alcohol, tobacco use and cannabis use that starts in adolescence has a strong continuity into parenthood. Reducing substance use in the perinatal period requires action well before pregnancy, commencing in adolescence and continuing into the years before conception and throughout the perinatal period.

Fentanyl in the labor epidural impacts the results of intrapartum and postpartum maternal and neonatal toxicology tests

BACKGROUND

A positive urine fentanyl toxicology test may have considerable consequences for peripartum individuals, yet the extent to which fentanyl administration in a labor epidural may lead to such a positive test is poorly characterized.

OBJECTIVE

This study aimed to quantify the extent to which neuraxial fentanyl in labor neuraxial analgesia can lead to a positive peripartum maternal or neonatal urine toxicology test.

STUDY DESIGN

We performed a prospective cohort study of pregnant participants planning a vaginal delivery with neuraxial analgesia. Participants with a history of substance use disorder, hypertension, or renal or liver disease were excluded. A urine sample was collected before initiation of neuraxial analgesia, each time the bladder was emptied during labor, and up to 4 times postpartum. Neonatal urine was collected once. Urine fentanyl testing was performed using 2 common toxicology testing methods, namely immunoassay and liquid chromatography with tandem mass spectrometric detection.

RESULTS

A total of 33 maternal-infant dyads yielded a total of 178 urine specimens. All maternal specimens were negative for fentanyl using liquid chromatography with tandem mass spectrometric analysis and immunoassay before initiation of neuraxial analgesia. Intrapartum, 26 of 30 (76.7%) participants had positive liquid chromatography with tandem mass spectrometry results for fentanyl or its metabolites, and 12 of 30 (40%) participants had positive immunoassay results. Postpartum, 19 of 21 (90.5%) participants had positive liquid chromatograph with tandem mass spectrometric results, and 13 of 21 (61.9%) had a positive immunoassay result. Of the 13 neonatal specimens collected, 10 (76.9%) were positive on liquid chromatography with tandem mass spectrometry analysis, the last of which remained positive 29 hours and 50 minutes after delivery.

CONCLUSION

Neuraxial fentanyl for labor analgesia may lead to positive maternal and neonatal toxicology tests at various times after epidural initiation and cessation and at different rates depending on the testing method used. Caution should be used in interpreting toxicology test results of individuals who received neuraxial analgesia to avoid false assumptions about nonprescribed use.

"A Lot of Things Stopped with COVID": Screening Pregnant Patients for Opioid Use and Related Conditions During the COVID-19 Pandemic

OBJECTIVE

We explored the impact of COVID-19 on universal screening programs for opioid use and related conditions among practicing clinicians or staff who work with pregnant patients.

METHODS

Semi-structured, in-depth qualitative interviews (n = 15) were conducted with practicing clinicians or staff in West-Central Florida between May and October 2020, representing both a range of professions and clinical settings that serve pregnant patients. Interviews were recorded, transcribed verbatim, and reviewed for accuracy. Independent coders conducted thematic content analysis iteratively in MaxQDA to identify emergent themes.

RESULTS

Four main themes were identified: worsening health and life conditions of pregnant patients, impaired patient-provider interactions, lack of priority and resources, and conducting opioid screening remotely. Pregnant patients often faced worsening mental health, lack of connection with health care providers, and socioenvironmental factors that increased the risk of overdose and intimate partner violence. Health care providers and facilities faced an infectious disease pandemic that simultaneously increased mental burden and reduced resources. Telehealth improved access to health care for many, but also came with implementation challenges such as inadequate technology, the need to address barriers to developing rapport with patients, and difficulty with certain social screens.

CONCLUSION

These themes describe facilitators of and barriers to implementing opioid and related screening programs during the COVID-19 pandemic, as well as the increasing urgency of screening because of socioenvironmental factors. Patients, health care providers, and health practices may benefit from emergency plans that anticipate screening challenges given their increased importance during times of heightened risk, including disasters and epidemics.

VULNERABILIDADE DE GESTANTES USUÁRIAS DE ÁLCOOL E OUTRAS DROGAS EM PRÉ-NATAL DE BAIXO RISCO

RESUMO Objetivo: verificar os contextos que potencializam as dimensões de vulnerabilidade individual, social e programática associadas ao uso de álcool e outras drogas durante a gravidez. Método: estudo qualitativo, descritivo e exploratório, com corte transversal. Participaram 38 gestantes usuárias álcool e outras drogas, em nível moderado e grave, em atendimento pré-natal de baixo risco na Atenção Primária à Saúde de dois municípios da Região Metropolitana de Maringá - Paraná. Os dados foram coletados de dezembro de 2019 a março de 2020. O referencial analítico da Vulnerabilidade pautou a discussão. Resultados: no plano individual, os contextos de vulnerabilidade eram questões de gênero, raça/cor parda e preta, baixa escolaridade, período reprodutivo e alta paridade. No plano social, a ausência de inserção no mercado de trabalho, renda familiar na linha da pobreza, relações intrafamiliares abusivas, comportamento aditivo na família e violência na comunidade de convivência. No plano programático encontraram-se baixa procura a serviços de saúde, ausência de acolhimento para o tratamento do uso de drogas, rastreio para o uso de drogas deficitário, baixo vínculo com as equipes da saúde da família, ausência de atendimento odontológico, psicológico e do serviço social, inserção no nível de assistência pré-natal inadequado, risco habitual, enquanto deveriam ter sido classificadas como alto risco, e média de consultas pré-natal abaixo do preconizado. Conclusão: o estudo permitiu avançar nos contextos de vulnerabilidade dessas gestantes. O (re)conhecimento destes contextos possibilita a formulação de estratégias de redução de danos e de agravos à saúde materno fetal relacionados ao uso de drogas durante a gravidez, conduzindo a um desfecho gestacional favorável.

VULNERABILITY OF PREGNANT WOMEN USING ALCOHOL AND OTHER DRUGS IN LOW-RISK PRENATAL CARE

ABSTRACT Objective: to verify the contexts that enhance the dimensions of individual, social, and programmatic vulnerability associated with the use of alcohol and other drugs during pregnancy. Method: qualitative, descriptive, and exploratory, cross-sectional study. Participants were 38 pregnant women who used alcohol and other drugs, at a moderate and severe level, in low-risk prenatal care in the Primary Health Care of two cities in the Metropolitan Region of Maringá - Paraná. Data was collected from, December 2019 to March 2020. The Vulnerability analytical framework guided the discussion. Results: at the individual level, the vulnerability contexts were issues of gender, brown and black ethnicity/color, low education, reproductive period, and high parity. At the social level, the lack of insertion in the job market, family income below the poverty line, abusive intra-family relationships, addictive behavior in the family, and violence in the living community. In the programmatic plan, there was a low demand for health services, lack of welcoming for the treatment of drug use, screening for deficient drug use, low bond with family health teams, absence of dental, psychological, and social services, insertion in the inadequate level of prenatal care, usual risk, while they should have been classified as high risk, and mean prenatal consultations below recommended. Conclusion: the study made it possible to advance in the contexts of the vulnerability of these pregnant women. Recognizing these contexts makes it possible to formulate strategies to reduce harm and damages to maternal and fetal health related to drug use during pregnancy, leading to a favorable gestational outcome.

Heterogeneity in prenatal substance use screening despite universal screening recommendations: findings from the Pregnancy Risk Assessment Monitoring System, 2016-2018

BACKGROUND

The American College of Obstetricians and Gynecologists recommends universal screening for tobacco, alcohol, and drug use as a part of routine prenatal care. However, little is known about the prevalence of prenatal substance use screening or factors that may contribute to differential rates of screening during prenatal care.

OBJECTIVE

This study aimed to describe the prevalence of prenatal substance use screening by substance, year, state, and state-level prenatal substance use policies and to examine individual-level factors associated with receipt of screening.

STUDY DESIGN

We analyzed 2016 to 2018 data from 103,608 women participating in the Pregnancy Risk Assessment Monitoring System, a population-based survey among women with recent live births. The Pregnancy Risk Assessment Monitoring System survey sampling weights were applied to all analyses. We described the percentage of individuals asked by a healthcare worker about substance use during a prenatal care appointment by substance, year, and state. Using chi-squared tests, we examined differences in the prevalence of screening by state-level prenatal substance use policies, including policies regarding classification of prenatal substance use as child abuse or neglect, mandatory testing or reporting of prenatal substance use, and targeted treatment funding and access for pregnant individuals with substance use disorders. Finally, we estimated the association between individual-level characteristics and receipt of prenatal substance use screening using logistic regression, controlling for year and state fixed effects and accounting for missingness using multiple imputation.

RESULTS

In 2018, approximately 95% individuals reported being asked about cigarette or alcohol use during a prenatal care appointment, whereas only 80% reported being asked about drug use. The percentage of individuals who were asked about substance use during a prenatal care appointment increased overall between 2016 and 2018, with variability across states. For all substances, states with laws designating prenatal drug use as child abuse or neglect had lower prevalence of screening, whereas states with laws mandating providers to test for substance use in pregnancy had higher prevalence of screening. Several individual-level characteristics were associated with increased odds of reported prenatal substance use screening for one or more substances, including being younger, less educated, unmarried, Black (vs White), non-Hispanic, or publicly insured (vs privately insured), receiving adequate prenatal care, and having a history of prepregnancy cigarette use.

CONCLUSION

Our study finds that despite recommendations for universal prenatal substance use screening, there are differences in who is actually asked about substance use during prenatal care appointments. This may be influenced by state-level prenatal substance use policies and selective screening approaches in which certain individuals are more likely to be asked about substance use during their prenatal care appointment. A better understanding of the repercussions of selective screening approaches on outcomes and the roles that policies, systems, and provider biases play in perpetuating these approaches is needed to advance guideline implementation efforts in prenatal care settings.

Concordance and discordance between maternal and newborn drug test results

BACKGROUND

Screening for substance use is recommended during pregnancy, and many clinicians rely on urine drug screening to identify newborns at potential risk for withdrawal.

OBJECTIVE

This study aimed to determine the concordance and discordance rates between maternal and neonatal drug testing at or near the time of delivery.

STUDY DESIGN

This retrospective chart review was performed at a single institution that employs universal testing for those who consent. Results of maternal and neonatal urine drug testing via immunoassay at delivery were compared.

RESULTS

Of 1573 singleton pregnancies, 233 mothers (14.8%) had a positive test result for any substance and 102 of their newborns (43.8%) had concordant positive test results. Of the 285 positive maternal test results for individual substances, 133 (46.7%) were concordant with newborn test results. After removing iatrogenic positives, there were 84 truly discordant pairs representing 5.9% of the total cohort of test pairs, but 29.5% of the pairs with maternal positive test results. When considering the outcome of a newborn positive test result, the overall sensitivity and specificity for the maternal test were 21.1% and 85.8%, respectively. The positive and negative predictive values were 46.7% and 96.4%, respectively. After excluding iatrogenic positive test results, the sensitivity and specificity for maternal testing were 97.8% and 99.4%, respectively, and the negative predictive value of maternal testing for all substances approached 100%. A total of 11 pairs of twins had at least 1 twin with a positive drug test result, and of these, 6 twin pairs (54.5%) had drug test results that were discordant from each other.

CONCLUSION

There is a high rate of iatrogenic discrepancy in maternal and neonatal drug testing. After adjusting for iatrogenic positive test results, the negative predictive value of maternal testing is high. Many discrepancies, such as those in twins, remained unexplained by medication administration, and potential reasons for these discrepancies warrant further investigation.

Early lessons from maternal mortality review committees on drug-related deaths-time for obstetrical providers to take the lead in addressing addiction

Problem:

In the United States, maternal mortality review committees (MMRC) are providing compelling data that drug-related deaths are emerging as a leading cause of pregnancy-associated death (death during pregnancy or up to a year postpartum). Recommendations from the MMRC consistently highlight screening all pregnant and postpartum women for drug use and improving access to evidence-based substance use disorder and mental health treatment. Unfortunately, many providers lack the confidence, skills and necessary resources to screen for substance use, provide basic behavioral health services or facilitate referral to high-quality services in their clinical settings. Our profession’s collective lack of response to a leading cause of maternal death represents a missed opportunity for potentially life-saving interventions.

A Solution:

We call on our fellow obstetrician gynecologists to incorporate the lessons learned from MMRC and integrate addiction assessment and treatment into prenatal and postpartum care. Provider level integration of behavioral health services is, however, insufficient to fully address the magnitude of drug-related maternal deaths in the US. We, therefore, ask colleagues to address the structural/systemic barriers to care identified in MMRC. By doing so, we can prevent drug-related maternal deaths.

Pain, Opioids, and Pregnancy: Historical Context and Medical Management

Women are being disproportionately affected by the opioid crisis, including during pregnancy. Pain and other vulnerabilities to addiction differ between men and women. Management of opioid use disorder should be gender informed and accessible across the lifespan. During pregnancy, care teams should be multidisciplinary to include obstetrics, addiction, social work, anesthesia, pediatrics, and behavioral health. Pain management for women with opioid use disorder requires tailored approaches, including integration of trauma-informed care and addressing psychosocial needs. Thus, coordinated continued care by obstetric and addiction providers through pregnancy into postpartum is key to supporting women in recovery.
