First-trimester pregnancy demise is a common experience, occurring approximately 1 million times annually in the United States alone.1 Satisfaction with clinical care in this context is driven by patients’ perception that the health care team is sensitive and compassionate and by effective two-way communication.2–4 The language used to describe a nonviable pregnancy is varied. In the 1980s, the published medical literature transitioned from using “spontaneous abortion” to “miscarriage”5; however, shifts in the terminology used clinically are not well documented. The American College of Obstetricians and Gynecologists’ (ACOG) Practice Bulletin titled “Early Pregnancy Loss” states that, “[i]n the first trimester, the terms miscarriage, spontaneous abortion, and early pregnancy loss are used interchangeably, and there is no consensus on the terminology in the literature.”6 Ultimately the ACOG Practice Bulletin uses the phrase “early pregnancy loss”. The ACOG reVITALize gynecology terminology selects the phrase “miscarriage/intrauterine pregnancy loss,” defined as “loss of a documented intrauterine pregnancy” and defines an early miscarriage as one that occurs before 10 weeks of gestation.7 Given this variability, it is not surprising that qualitative studies have identified patient dissatisfaction with health care provider communication at the time of loss diagnosis as an area for quality improvement.8,9

The lack of consensus surrounding the terminology provides an opportunity to engage patients and identify language that enhances patient–clinician communication.10 To gain insight into the patient experience with the language of first-trimester pregnancy demise, we surveyed women participating in a multisite randomized trial of medical management of early pregnancy loss.

METHODS

This language preference cross-sectional study was a substudy embedded within a randomized trial of medical management of early pregnancy loss conducted from May 2014 to May 2017 at three sites: University of Pennsylvania, University of California–Davis, and Albert Einstein College of Medicine. The primary results of this trial are published elsewhere and included clinically stable women diagnosed with a nonviable pregnancy between 5 and 12 completed weeks of gestation.11 This language preference survey was developed and implemented as a protocol modification after the larger trial had already begun enrollment. We constructed a six-item instrument to assess participant terminology preferences. All data were collected as part of the clinical trial using REDCap, and all demographic data were obtained from the primary study.

We pretested our survey for external validity with 12 voluntary participants approached in the waiting room of a family planning clinic, half pregnant and half not pregnant, but none with a known diagnosis of an abnormal pregnancy. We then performed a pilot test for internal validity within the PreFair trial on 23 participants, which allowed us to make our ultimate modifications. All English-speaking trial participants enrolled between November 2015 and May 2017 received the language preference survey. All participants provided written informed consent as part of the larger trial. The institutional review boards of participating sites approved this study and survey language.

We chose to query participants about the terms “spontaneous abortion,” “miscarriage,” “early pregnancy loss,” and “early pregnancy failure,” because the first three are referenced as interchangeable terms by the ACOG Practice Bulletin, and the fourth term, “early pregnancy failure,” is often used in medical literature.6,7,12

We asked all participants to report which of these terms they heard during their clinical encounters for this pregnancy. We additionally asked what word they would prefer their doctors to use to describe their diagnosis (“spontaneous abortion,” “miscarriage,” “early pregnancy loss,” or “early pregnancy failure”) and to score these four terms on a 100-mm visual analog scale (VAS) from “least clear” to “most clear.” The VAS has been shown to be a valid scale type for assessing patient satisfaction13 and can discern subtler distinctions than an ordinal scale.14–16 However, when the distribution of the VAS measures for clarity were evaluated, they were bimodal (responses clustered at the low end of the scale [least clear] and the high end [most clear]). We then derived a new dichotomous clarity variable for each term where the term was 0 if the VAS score was less than 50 and 1 when clarity score was 50 or greater mm. A score greater than 50 mm on the VAS was considered to be clear. Descriptive statistics were performed with analysis of variance for continuous variables and χ2 and Fisher exact test for categorical variables. We tested associations between terms heard and demographic characteristics. Separate models were developed for clarity and preferred term, with “early pregnancy loss” considered as the reference based on ACOG’s use of the term in the most recent Practice Bulletin.6 All multivariable models used a backward stepwise approach of all baseline variables identified as associated with the outcome from bivariate tests of association. For the analysis of preferred term, a multivariable multinomial logistic regression model was developed to determine whether terminology preferences varied depending on demographic characteristics. The four women who indicated that their preferred term was “spontaneous abortion” could not be included in this analysis because this group’s size was too small. Clarity for each term (0 vs 1) was modeled jointly using a generalization of the logistic regression model, which accounts for the correlation among responses within individuals using a generalized estimating equation approach using the xtgee command in Stata 14.2.

RESULTS

We received completed surveys from 145 of 155 approached patients at the three sites for a total response rate of 93.5%. The mean age of participants was 30.3±6.1 years, and the majority of respondents self-identified as black–African American or white (n=65 [44.8%] and n=62 [42.7%], respectively). Fifty-two (35.9%) participants self-identified as Hispanic or Latina (Table 1).

Participant Demographics by Term Preferred for Nonviable Pregnancy Diagnosis

Participants most frequently chose “miscarriage” as their preferred diagnosis term (n=79 [54.5%]), followed by “early pregnancy loss” (n=49 [33.8%]), whereas fewer participants chose “early pregnancy failure” (n=11 [7.6%]) or “spontaneous abortion” (n=4 [2.8%]) (Fig. 1A). The distribution of terminology preference (Table 1) varied significantly by ethnicity (P=.02), study site (P=.001), and history of induced abortion (P=.01). Two participants chose “none of the above” when asked to select their preferred term and thus were excluded from the analysis. Neither of these participants offered a suggestion for alternative language. We found no differences in the distribution of preferred term by intendedness of the pregnancy (P=.17) or gestational age of the current pregnancy (P=.30). When compared with “early pregnancy loss,” “early pregnancy failure” was less preferred (11/145 vs 49/145 for “early pregnancy loss,” adjusted risk ratio [RR] 0.34, 95% CI 0.16–0.73, P<.006) and “miscarriage” was more preferred by participants (79/145, adjusted RR 2.48, 95% CI 1.53–4.02, P<.001) after adjusting for site and ethnicity (Table 2). Because only four participants (2.8%) chose “spontaneous abortion” as their preferred term and, as a result of this low frequency, we omitted this term from the multivariable model of preference.

Multivariable Logistic Models for Clarity and Preferred Terminology

Eighty-two percent of women found the term “miscarriage” (82.1%) to be clear followed closely by “early pregnancy loss” (81.4%) and “early pregnancy failure” (63.4%) with only 36.6% of women indicating the term “spontaneous abortion” was clear. (After controlling for potential confounders [study site, ethnicity, race, history of induced abortion, and whether the current pregnancy was planned], we found “spontaneous abortion” and “early pregnancy failure” to be significantly less clear than “early pregnancy loss” [53/145, adjusted RR 0.12, 95% CI 0.07–0.19, P<.001 and 92/145, adjusted RR 0.38, 95% CI 0.24–0.61, P<.001, respectively, vs 118/145 for early pregnancy loss]). “Miscarriage” scored similarly to “early pregnancy loss” in clarity rankings (119/145, adjusted RR 1.05, 95% CI 0.62–1.77, P=.86) (Fig. 1B; Table 2).

Individual participants heard multiple terms throughout their encounters for diagnosis. Patients most commonly heard the terms “miscarriage” (n=109 [75.2%]) and “early pregnancy loss” (n=73 [50.3%]). We did not find any statistically significant differences in the bivariate analyses of participant demographic characteristics and terms most commonly heard. Although participants did not hear the less preferred terms as frequently as the more preferred terms, 14.4% of participants heard “spontaneous abortion” (n=21) and 21.3% of participants heard the phrase “early pregnancy failure” (n=31) during their care.

DISCUSSION

“Miscarriage” was found to be the most preferred of the four suggested terms when trial participants were asked to select a single term to label their diagnosis of a nonviable first-trimester pregnancy. However, when asked to rate the clarity of each of the terms individually, there was no difference between “miscarriage” and “early pregnancy loss,” making both of these terms suitable for use. The terms “spontaneous abortion” and “early pregnancy failure” were classified as less clear and less preferred by patients and thus should not be the first-choice terminology.

Our data were collected as part of a clinical trial of women with first-trimester pregnancy demise, which may limit generalizability. However, we included women from diverse geographic locations in the United States, and our population was sociodemographically varied. We included only women who self-identify as English-speaking, and results may be different for women who speak other languages. The complex nature of language and how women from different backgrounds understand words differently are highlighted by our finding that terminology preferences varied by race and ethnicity. Although those who identified as Hispanic also preferred the terms “miscarriage” and “early pregnancy loss” overall, they were more likely than others to prefer the terms “early pregnancy failure” and “spontaneous abortion.” When adjusting for these differences, our findings show an overall superior clarity and patient preference for “miscarriage” and “early pregnancy loss.” Level of education did not significantly influence clarity level or language preference choice between these two terms so they can be used for women from a range of educational backgrounds.

The prevalence of unintended pregnancy was high in our sample and representative of the U.S. population.17 We did not find differences in language preferences according to intendedness of the pregnancy. This finding is supported by a recent study that suggested that pregnancy loss can affect women in complex and seemingly contradictory ways regardless of original reactions to the pregnancy.18 Our univariate analysis did show differences in language preference among women who stated they had a history of induced abortion compared with those who did not. A prior study in a similar population showed that history of induced abortion influences women's decision-making at the time of miscarriage treatment, both because the treatments for two conditions are similar and prior abortion experience provides a knowledge base, and because some women wished to distance their miscarriage experience from their abortion experience.2 Our data did not suggest that women with a history of a prior miscarriage have unique language preferences.

Limitations of the study include that we did not identify the point of care at which each of these terms were heard, so it is possible that participants selected the two most clear and preferred terms because they were more familiar from their treatment course. Additionally, this study is limited by the fact that all data were self-reported by participants and there were no objective recordings or data reflecting what was actually said by clinicians.

“Spontaneous abortion” was the least commonly heard term, which is consistent with its diminishing use in the medical literature.5 The clinical meaning of “abortion” is “the spontaneous or induced termination of pregnancy before the fetus reaches a viable age,”19 but sociopolitical forces have coopted the term to primarily infer induced abortion, which is accompanied by stigma that women with fetal demise may find additionally alienating (Woodroffe C. Miscarriage or abortion [letter]. Lancet 1985;326:1245.).

Our findings suggest that, of the currently used diagnosis terminology, both “miscarriage” and “early pregnancy loss” are acceptable, clear terms within our lexicon for discussing first-trimester pregnancy demise with patients from a variety of backgrounds. Others have called for a shift in language choice to the use of “miscarriage.”20 Our data support that patients, too, prefer the term “miscarriage” to all other commonly used terms. However, given that just more than 50% of participants chose “miscarriage” as the most preferred term, additional research to improve patient-centered communication is warranted. For now, clinicians and the systems that support clinical practice can improve communication by preferentially using the terms “miscarriage” and “early pregnancy loss.”
