Complex Calculations: How Drug Use During Pregnancy Becomes a Barrier to Prenatal Care

Pregnant women who use drugs are more likely to receive little or no prenatal care. This study sought to understand how drug use and factors associated with drug use influence women’s prenatal care use. A total of 20 semi-structured interviews and 2 focus groups were conducted with a racially/ethnically diverse sample of low-income women using alcohol and drugs in a California county. Women using drugs attend and avoid prenatal care for reasons not connected to their drug use: concern for the health of their baby, social support, and extrinsic barriers such as health insurance and transportation. Drug use itself is a barrier for a few women. In addition to drug use, women experience multiple simultaneous risk factors. Both the drug use and the multiple simultaneous risk factors make resolving extrinsic barriers more difficult. Women also fear the effects of drug use on their baby’s health and fear being reported to Child Protective Services, each of which influence women’s prenatal care use. Increasing the number of pregnant women who use drugs who receive prenatal care requires systems-level rather than only individual-level changes. These changes require a paradigm shift to viewing drug use in context of the person and society and acceptance of responsibility for unintended consequences of public health bureaucratic procedures and messages about effects of drug use during pregnancy.

Pregnant women who use drugs are over-represented among women who receive late, limited, and no prenatal care [1, 2, 3, 4, 5]. Similar to pregnant women in general , women who use drugs and receive adequate prenatal care generally have better pregnancy outcomes than women who use drugs and do not receive adequate care [7, 8, 9, 10, 11, 12, 13, 14, 15, 16]. It is unclear whether these improvements are due to prenatal care or if lack of prenatal care is a proxy for other risk factors associated with poor outcomes [13, 17]. Nevertheless, lack of prenatal care clearly limits opportunities for offering other health promoting interventions.
The limited research suggests that women who use drugs during pregnancy face the following barriers to prenatal care: difficulties with transportation and health insurance , “drug lifestyle” , fear of having drug use identified by providers , and fear of legal repercussions , including Child Protective Services (CPS) reports . In addition, a recent study examined whether drug use itself or factors associated with drug use are barriers . The study found that both drug use and factors associated with drug use are barriers, although this differs depending on the specific drug.
The existing research primarily tests researchers’ a priori hypotheses . Thus, it may exclude some key barriers. In addition, it has focused on determining the most common barriers  and on determining which risk factors explain the most variance in limited prenatal care . While each are important, they do not provide information on how drug use or factors associated with drug use become barriers to prenatal care. With the goal of informing interventions to reduce barriers to prenatal care for women who use drugs during pregnancy, this qualitative study identifies women’s perspectives on barriers to prenatal care and seeks to understand the processes through which drug use and factors associated with drug use during pregnancy become barriers.
This exploratory qualitative research was conducted between September and December 2006 in a northern California county. The county has a population of just over one million people, and is diverse in terms of race/ethnicity, income, and rural/urban status. Goals were to identify barriers to prenatal care and factors that encourage use of prenatal care by pregnant women who use alcohol and/or drugs and engage women in identifying strategies to reduce barriers. Human Subjects approval was obtained from University of California, Berkeley and informed consent was obtained from each participant.
Women with current alcohol and/or drug use or a history of substance abuse who were pregnant or had a child 2 years old or younger were eligible and were recruited from substance abuse treatment, a home-visiting program, and the Women, Infants, and Children (WIC) Program. Staff at these sites recruited women through a standardized script and posted flyers. Women then self-identified to the lead investigator (first author) either by phone or when she was onsite at the agency/organization. The intention of this purposive sampling strategy was to find pregnant women and new mothers who were currently using alcohol and/or drugs or had a history of alcohol and/or drug use during pregnancy who could talk about challenges that pregnant women who use alcohol and/or drugs face in entering and continuing prenatal care. Despite our intention of including women who used alcohol only, both alcohol and drugs, and drugs only, our sample only includes women using drugs, either alone or in combination with alcohol. It does not include women using alcohol without drugs.
Thirty-eight women participated. Twenty semi-structured interviews  and two focus groups (with eight and ten women each) were conducted. About one half of interview participants (n = 11) and all focus group participants were recruited from treatment. Interview and focus group guides addressed: women’s thoughts about and experiences with prenatal care; barriers and facilitators to prenatal care for women who use alcohol and/or drugs; and women’s thoughts about how the health department and health care providers could encourage women who use alcohol and drugs to enter prenatal care earlier, including ideas for a community awareness campaign. Women were also asked close-ended questions about demographics, timing of entry to prenatal care, and type of substance (alcohol and/or which drug) they used. Focus group participants provided this information in exit surveys. Due to an error with exit survey printing, women in focus groups were not asked questions about timing of prenatal care entry. The questions about alcohol and drug use were used to classify participants as using alcohol only, alcohol and drugs, or drugs only. Women were treated as study participants, key informants, and collaborators in community awareness campaign development. Women who were not pregnant at study participation (74%) were asked about their most recent pregnancy.
Interviews and focus groups lasted approximately 60 and 90 min, respectively and were recorded on audiocassette. Participants received $30 and $20 Target gift cards for interviews and focus groups.
Interviews and focus groups were transcribed verbatim and supplemented by notes. The transcriptions, combined with women’s drawings of their ideas for the community awareness campaign, served as the basis for the analysis.
Coding was completed in a multiphase, iterative process. We had some general ideas of the barriers women might report prior to initiating the study. However, we did not have an a-priori coding scheme. Initial codes were developed in an inductive process  based on the first nine interview and both focus group transcripts. Codes were then added and refined based on the remaining eleven interviews. A codebook was created and then used to code the entire set of interview and focus group transcripts. Memos were used during coding to track ongoing analysis insights and after coding was completed to explore different aspects of identified themes and determine the number and quality of quotations supporting themes and different aspects of themes .
Case-studies, a cross-case study, and typology were also used . Case studies of each interview participant were created to document the timing of prenatal care entry in relation to drug use cessation and factors that facilitated or hindered prenatal care entry. A cross-case study using data from all interview participants then categorized each woman based on her trimester of prenatal care entry and timing of drug use cessation. Health insurance status and previous CPS involvement emerged as themes and were added to the cross-case study. Timing of prenatal care entry, timing of drug use cessation, and structural barriers were then graphed to explore the relationships between timing of each behavior and structural barriers. Fisher’s exact tests were used to test (1) whether problems with health insurance were associated with entry after first trimester and (2) whether entering after first trimester and/or having stopped use before entering were associated with previous CPS involvement. The statistical significance of the second test differed depending on whether the denominator was restricted to only those with at least one child prior to the index pregnancy; however, the trend was in the same direction for both. Findings from the full sample are reported. Finally, women were categorized based on how they responded to common fears, such as fears of being reported to CPS. For example, a typology  was created based on subthemes of similarities and differences  in ways that women respond to their fears of being reported to CPS in relation to prenatal care.
Validity checks included (1) respondent validation, where initial findings were shared with other women similar to initial participants, staff at agencies where participants were recruited, providers, and policymakers and feedback requested; (2) field time of more than 3 years that the lead investigator spent in the study setting; (3) use of multiple methods of data collection (interviews and focus groups) to triangulate findings relating to barriers to and facilitators of prenatal care; and (4) checks of how supported a key finding relating to fear of CPS was both across and within interviews [26, 27]. This final check was conducted after coding was completed to ensure that our finding was not driven by only one or two interviews.
Participants were a racially and ethnically diverse sample of 38 low-income English-speaking pregnant and parenting women. About one-fourth (26%) were pregnant at the time of study participation. Those who were not pregnant had a child 2 years old or younger. Most had received some prenatal care in their most recent pregnancy: 50% (n = 10) of those participating in individual interviews entered in their first trimester; 25% (n = 5) second trimester; and 20% (n = 4) third trimester. Five percent (n = 1) received no prenatal care. Most women used more than one substance. Methamphetamine (61% n = 23) and crack/cocaine (16% n = 6) were the most common primary substances. Many used alcohol (42% n = 16), but none reported an “alcohol only” pattern of use.
“Same Reasons Somebody Who’s Not Using Goes”
Having health insurance, a belief in the utility of prenatal care, and social support also facilitated prenatal care use.
[Prenatal care] affects a baby a lot. If, you’re having any conditions or whatever, then [doctors] can, it minimizes the chances of your child being born with deficiencies.
With the doctor monitoring the baby and finding out if it’s going to be a healthy baby, if everything’s gonna be ok, if everything’s growing right, [if] all the toes and fingers are there. That way they can detect infant problems early on and maybe help that situation.
He wasn’t answering my questions, he was very rushed. I’m trying to ask questions and he answered them on his way out the door. Then when I switched over to [new prenatal care site] I was voicin’ concerns about my pregnancy and they were just pushed off, not taken care of, pushed off. I wasn’t happy about that.
Drug Use as Barrier
Dope prevented me from going [to the doctor]…My husband kept trying. He tried driving me, making appointments for me, everything. I was just too doped up to hear anything.
Drug Use and Extrinsic Barriers
Multiple Simultaneous Risk Factors
Some women saw drug use as related to and even as causing some extrinsic barriers. For example, one woman reported having been with a boyfriend in another town using drugs and not having her own transportation to get to prenatal appointments. Other women talked about how drug use left them with few resources, which then made it difficult to resolve the barriers. As one explained:
I had always intended on going and having prenatal care, but the first blocker was the welfare department and getting Medi-Cal…They had denied me Medi-Cal because I was homeless [and therefore didn’t have an address].
Resolving bureaucratic barriers took persistence and determination. Drug use made resolving bureaucratic barriers more difficult because of both competing priorities and system gaps. Drug use itself, the stress of reducing or managing drug use, and the stress of leaving abusive partners with whom women used drugs were factors that women described as making it difficult to prioritize resolving bureaucratic barriers.
[My drug use made it hard for me to get an] appointment because by the time I found out I was pregnant, I had zero dollars, zero friends, a car that I couldn’t drive, I didn’t have internet, I didn’t have telephone, and finding services to get the ball rolling in that way. Then in the phone book it doesn’t exist. So if you don’t have internet access, you’re kind of in the dark.
I didn’t have Medi-Cal. I was very confused about how to go get emergency Medi-Cal, how it would only last for like 90 days and then how I’d have to go back and re-apply and then have to wait for that to come through, and how to find a doctor. It took me the longest time to try and see a doctor. My sister, she got pregnant and she sees own her private doctor, she also has Medi-Cal. It’s just like, why is it so easy for her and like the world coming down on and I don’t know what to do…People were telling me you need to see a doctor, but you need to wait for all these things to come through, and it was just stressful. Especially for someone who’s coming off drugs and trying to do what they’re supposed to. Even just getting through 1 day is stressful.
Some women also reported having unique concerns or situations related to their drug use that conflict with bureaucratic procedures. For example, a few women mentioned drug-related paranoia. One woman explained how this paranoia made it difficult to complete forms in public places.
[I had gotten pregnant] through a sexual abuse with my ex [who introduced me to meth], so part of me shut down emotionally and didn’t want to even accept that I [was] pregnant…[so], prenatal care wasn’t high on my list, [figuring out how to get insurance] kind of just got pushed to the side because of my emotional issues, trying to deal with how I was going to leave him.
Other women mentioned delays in discovering pregnancy. Some saw these delays as due, in part, to drug use. These delays led to them to begin obtaining insurance and scheduling appointments later in pregnancy. Starting these processes later created additional barriers, especially with scheduling appointments.
You can’t fill out Medi-Cal forms and everything if you’re paranoid. You’re afraid everybody’s looking at you, or everybody sees that you’re on drugs.
I didn’t know where to go, my boyfriend just drove me to [county clinic] to make an appointment. We just waited in that line at the information window 12 over there, the information booth, went up to the window and said I’m pregnant. The woman said, how far along are you? I hadn’t seen a doctor at that point so I had no clue. So, she said, let me see your stomach. And she said, oh you can’t be more than 3 or 4 months pregnant. But it turned out that I was 6½ or 7 months pregnant at that time. Wow. So really I should have been seen at that time. ‘Cause I went on her word, I waited to figure out where to go.
I started with the doctor she referred me to, took him a week to call me back, and then he told me he couldn’t take me because I was past 7 months along, and he didn’t take patients that far along.
Drug Use and Social Support
Partners sometimes helped resolve extrinsic barriers.
The lady across the street [from my parents], actually, our neighbor, who was the administrator at [local hospital], she, at one point, probably was the one that told my mom, look at Medi-Cal.
It was the first couple of days I was [at the treatment program] and there was a pregnant girl there that told me ‘cause I had been tryin’ to get the Medi-Cal straightened out.
In contrast, some women reported that their drug use isolated them from their families and other non-users. Some took steps to hide drug use and pregnancy from family and non-using partners, making it difficult to obtain support.
My boyfriend kind of went the extra mile for me. He helped me get out of bed, made me go even when I didn’t want to go stand on long lines just to get turned down, [helped] when we needed to sell our stuff so we could get gas money so we could go [to the] county [office].
Other women reported that when they reduced or stopped drug use, they lost access to drug-using friends and partners who wanted them to continue to use drugs with them. Conversely, a few also reported exclusion from drug-using networks due to pregnancy.
[My family] didn’t even know I was pregnant. I did hide for about 7 months because I didn’t show very well till about 7 months. I was trying to hide it anyways, ‘cause that first step, admitting you’re pregnant with the person they hated and despised and knew he was a druggie and causing problems with me.
Exclusion from these networks made it more difficult to obtain informational support to resolve extrinsic barriers.
People don’t give you drugs when you’re pregnant.
Drug Use and Desire for Healthy Baby
Some addressed their guilt and concerns by attending prenatal care. Of women who attended, some reported doing so to compensate for the effects of drug use.
That guilt of knowing that you’ve used, ‘cause you know 9 times out of 10 [it] will affect your baby in some way form or another.
A key component of compensating was obtaining prenatal vitamin prescriptions, which many women saw as having important health benefits. A few saw taking vitamins as helping compensate for drug use.
[I’m glad that I went to the doctor during my pregnancy] because I was able to see that my child was growing healthy and that I was doing all the right things as far as my diet and making sure that I ate lots of folic acid and stuff at the same time I was using.
Some women also attended because they believed the doctor might discover and therefore minimize problems associated with drug use.
The baby has got to be healthy. I mean I need the prenatal pills. They[‘re] for the baby. I knew I wasn’t eatin’ right. I wanted to get as much nutrition, vitamins, minerals and everything that the baby needed as possible. So I made sure that I went to the doctor, and took my pills and ate as healthy as possible.
Other women attended to get reassurance that their baby was healthy. This reassurance helped relieve stress and anxiety.
It’s extremely important [to attend prenatal care] especially in the fact that you use drugs because if you let your provider know, they can make sure to check for…difficulties or problems that might arise from your use and you can minimize a lot of damage that way.
Simply attending prenatal care also relieved guilt for some women by helping them feel they were doing something right. This feeling that they were doing something right, in turn, helped them feel good about themselves.
I was so worried because I had used in the first couple of months that…there was going to be something wrong with my baby. Being able to go to prenatal care took a lot of that stress off me, ‘cause they’re telling me my baby’s ok and I’m not this and I’m not that. That relieved a lot of stress on my part, a lot of stress.
Learning from the doctor they had harmed their baby by using drugs would have increased guilt. Others tried to deal with the guilt on their own. Some tried to reduce or stop their use. Others continued drug use to escape from guilt. Each led to delays in prenatal care entry.
The more clean I got, I was like out of there, I was like tripping, like hella trippin’…I d[id]n’t know what’s going on with my kid. The guilt was really bad. I was scared, I didn’t want to know. I really didn’t, I did not want to know if there was anything wrong.
When women used drugs to calm their guilt, this use sometimes increased guilt. Women reported that both the drug use and the increased guilt from the drug use then made it more difficult to attend prenatal care.
The drugs lie to you in your brain, they tell you everything’s gonna be ok, to don’t worry about it, just smoke me, smoke me. But at the same time, you’re knowing deep down in the back of the mind, especially when you’re coming down off the shit, you know what I mean?…When you’re coming down off of it, that’s when you’re feeling guilty about it, that’s when you really start to feel guilty and that’s when you regret. Until you get that next hit of course.
Drug Use and Fear of CPS
Most women avoided prenatal care or attempted to stop using drugs before attending prenatal care because of fear of CPS [See Fig. 2].
When you’re using and you think about prenatal care, you’re nervous and you’re scared because you don’t want anybody to take your baby. That’s the first thing on your mind.
A few attended in spite of fear of CPS because they prioritized their baby’s health. One woman who used methamphetamine and marijuana throughout her pregnancy explained:
I didn’t [go while] I was using because I was afraid that, if they had known, that CPS would have been involved, that Social Services would have taken my baby.
That whole time, that whole 9 months, you’re like, I cannot go to this doctor because if I do, they’re gonna take my kid or put [me] in jail for the rest of [my] 9 months just to take the baby when [I deliver].
Others attended because of fear of CPS. They saw prenatal care as increasing their chances of keeping the baby with which they were currently pregnant and reunifying with children who had been removed.
[Fear of CPS] made me not want to go, but because I was high risk, there was a greater chance of, I care more about my son being ok…so, I never missed a[n] appointment.
One of the reasons I went was because I didn’t want them to take the baby away.
Participants reported similar barriers to prenatal care as low-income women in general [29, 30, 31]. In addition, both drug use and factors associated with drug use influence prenatal care use. Drug use itself is a reason a few women do not attend prenatal care. However, for most women, drug use became a barrier to prenatal care by interacting with additional individual, interpersonal, systems, and policy-level factors. First, as has been found previously, pregnant women who use drugs face multiple barriers [32, 33]. Experiencing multiple barriers simultaneously makes resolving each barrier more difficult. They also may be especially at risk for certain bureaucratic barriers, such as finding doctors willing to start seeing women during their third trimester. Second, women believe that drug use during pregnancy is very harmful to the fetus. While a motivator to attend prenatal care for some women, this belief appears to scare other women to the point that they delay entering prenatal care. Women’s beliefs are consistent with some public health messages about effects of drug use during pregnancy [34, 35, 36]. It is important to note that recent research suggests that drug use during pregnancy may not be as harmful as women believe and public health messages suggest [37, 38]. Third, women report isolation from potentially supportive networks due to their drug use during pregnancy. These same messages may stigmatize women who use drugs during pregnancy. This stigma appears to isolate women from social networks that could facilitate prenatal care use. Finally, as suggested by ACOG and found by other qualitative, but not quantitative research [18, 22, 23, 39], fear of CPS reports is a common and significant barrier. Fear of CPS reports may be warranted based on current policy and practice [40, 41, 42]. While drug use itself is a factor for some women, it does not appear that late or limited prenatal care among women who use drugs is caused solely by drug use itself. Rather, late or limited prenatal care may be better understood as one rational response to public health messages and CPS reporting practices, and as an indicator of systems-gaps.
These findings should be interpreted in light of the study’s limitations. First, the sample is a small non-representative sample of agency-involved women in one county. Second, few participants were using drugs at the time of participation and many were or had been involved with CPS, each of which may have influenced what they chose to focus on during interviews and focus groups. Third, the assessment of alcohol and drug use only included questions about type of substance and did not include quantity/frequency questions or questions about problem severity, which limits generalizability. However, the questions asked suggest that findings apply to women who use methamphetamine or cocaine, either alone or in combination with marijuana, alcohol, and other drugs; and may not generalize to women using opiates or using marijuana only, because they were not represented in the sample. However, more research with better alcohol/drug measures is needed to confirm these findings and to determine whether women with more or less frequent use or more or less severe problems experience the same barriers. Fourth, other counties may respond differently to drug use during pregnancy and may have different systems, such as easier third-trimester entry to care or services to assist homeless women obtain insurance. Finally, the direction of causality between drug use and extrinsic barriers is not possible to determine. While some participants spoke of their drug use as causing the barriers, it is possible that any association between the two is not a simple uni-directional causal relationship  and that each indicate higher risks from more distal factors .
This study also has strengths. Findings are largely consistent with prior research on barriers to prenatal care for pregnant women who use drugs [18, 19, 22, 23]. However, this research also extends previous research by (1) identifying new barriers that have not been previously documented—fear of the effects of drug use and isolation from social networks; (2) finding additional support that fear of CPS is a barrier; (3) identifying how drug use becomes a barrier; and (4) regardless of the direction of causality, describing ways in which multiple simultaneous barriers make it more difficult to resolve barriers. This study also extends previous research by identifying systems-level barriers, including those related to public health bureaucratic procedures, messages, and CPS reporting policies/practices, rather than solely focusing on individual-level risk factors.
Findings suggest that reducing the number of pregnant women who use alcohol and drugs who receive late or limited prenatal care requires more than telling women to stop drug use. It requires acknowledging the complexity of women’s decision-making about prenatal care, the diversity among women who use drugs during pregnancy, and a focus on changing systems and not solely getting women to change. Some interventions that may increase prenatal care utilization are: (1) new messages about the effects of drug use during pregnancy that identify steps that pregnant women who have already used drugs can take to increase chances of having healthy babies; (2) clarified CPS reporting policies; (3) streamlined insurance applications; and (4) easier access to providers who accept women in their third trimesters. Addressing these systems-level barriers as opposed to focusing on drug use as an isolated and silver-bullet risk factor will require a paradigm shift to viewing drug use and prenatal care utilization in the context of multiple interacting risk factors and social environment [33, 45, 46]. It will also require increased recognition that public health messages and bureaucratic procedures can create barriers and acceptance of responsibility for unintended  and potentially iatrogenic  consequences of these messages and procedures.
