1. Introduction
A perineal incision (episiotomy) is a surgical procedure involving the controlled cutting of perineal tissues, including the skin, vaginal mucosa, superficial transverse perineal muscle, and sometimes the anal levator muscle [
1], to widen the vaginal outlet during the second stage of labor. In the modern approach—where evidence-based medicine (EBM) is implemented in clinical practice—it has been shown that the routine incision of the perineum is not beneficial and should be performed only according to strictly defined indications [
2,
3,
4,
5].
There are two types of perineal incision: median (midline) and mediolateral. When an incision is necessary, a mediolateral incision is recommended, as it is associated with a lower risk of grade III and IV perineal ruptures. In contrast, a midline incision clearly increases this risk [
6,
7]. Indications for episiotomy include the presence of life-threatening fetal symptoms (e.g., bradycardia requiring the faster termination of labor) [
8], shoulder dystocia during labor [
5], operative delivery (particularly with obstetric forceps) [
9], fetal macrosomia, or other factors that increase the risk of injury to the mother and child [
10]. The procedure is intended to reduce the risk of grade III and IV perineal ruptures [
11,
12]. According to World Health Organization (WHO) guidelines, episiotomy should be performed in no more than 10% of parturients [
5]. However, Polish data indicate that episiotomies are still performed too frequently, with wide variation between hospitals—ranging from 20% to 86% of all births [
13].
Evidence-based practice is a natural part of patient care—this approach promotes the implementation of management strategies supported by current data that are more likely to benefit than harm the patient [
14,
15,
16,
17,
18,
19]. However, the perineal incision procedure appears to deviate from this approach. The percentage of women who undergo episiotomy varies significantly depending on the country in which the data were collected [
20,
21]. Moreover, substantial discrepancies exist even within the same country, depending on the hospital [
13,
21]. An analysis of published studies on women’s awareness of perineal incision reveals significant differences among populations. Haji et al. [
22] found that 30.3% of respondents in Saudi Arabia had never heard of episiotomy. In a Nigerian study, Inyang-Etoh et al. [
23] reported that 32% of respondents were unfamiliar with the term before delivery. In another Nigerian study, nearly 19% of pregnant women surveyed had never heard of the procedure [
24].
The aim of this study was to assess Polish women’s knowledge of perineal incision depending on age, education, the place of residence, past childbirth, and the source of knowledge, including the Internet, medical staff, medical staff on social media, and scientific articles.
2. Materials and Methods
Between 15 June 2023, and 30 July 2023, a total of 469 completed questionnaires were collected. This study was conducted using a self-created, unvalidated, anonymous questionnaire created in Google Forms (written in colloquial language understandable by all patients). Participation was voluntary and conducted entirely online. The inclusion criteria were female gender after natural childbirth. Patients with a history of cesarean section or vacuum forceps use, as well as male participants, were excluded.
The survey was distributed via the social media platforms Instagram and Facebook. The post containing the questionnaire was shared in the following groups:
1. “I give birth in Polna”—a support group for women giving birth in the Gynecological and Obstetrics Clinical Hospital named after H. Święcicki of the K. Marcinkowski Medical University in Poznań.
2. “I give birth in Raszei”—a support group for women giving birth in the Department of Gynecology and Obstetrics with Pregnancy Pathology, Franciszek Raszeja Municipal Hospital in Poznań.
3. “Studentawka”—a group that brings together both people directly interested in student issues and those who need support and help in this area. In addition, five people shared the questionnaire with their friends on Facebook.
The first section of the questionnaire collected basic demographic information, including age, education, the place of residence, sources of knowledge, and past natural childbirth (this was not subject to secondary verification). This study examined knowledge of various aspects of perineal incision: women’s knowledge of perineal incision, indications for perineal incision, and methods of perineal protection. We initially considered a composite knowledge score, but this approach was not retained following peer-review feedback, given the heterogeneity of knowledge items and lack of standard scoring criteria.
A statistical analysis was performed to evaluate Polish women’s knowledge of perineal incision depending on age, education, the place of residence, past childbirth, and the source of knowledge, including the Internet, medical staff, medical staff on social media, and scientific articles. Associations between categorical variables were tested using the Chi-square (χ2) test of independence.
Data analysis was performed using Statistica (Cloud Software Group, Inc., Fort Lauderdale, FL, USA (2023), Data Science Workbench, version 14) and Microsoft Excel (Microsoft Office, Redmond, WA, USA (2019), version 2205). A significance level of p < 0.05 was applied in all calculations.
4. Discussion
Perineal incision or perineal protection? Until recently, a surgical perineal incision to widen the birth canal and facilitate the course of labor was a routine procedure conducted during the second stage of natural childbirth. Currently, World Health Organization experts recommend the use of perineal incision in only 5% to 20% of births [
5,
25]. The proper preparation of perineal tissues, the option of delivering in a vertical position, and physical activity during pregnancy significantly increase the likelihood of childbirth without the need for an incision. In the present study, nearly 74% of respondents identified physical activity during pregnancy as a means of protecting the perineum, and 83% mentioned pelvic floor muscle exercises. Warm compresses were noted by nearly 42% of women.
Sun et al. [
26] reported a significant reduction in the number of grade III and/or IV perineal injuries (RR 0.46, 95% CI 0.27–0.79), a decrease in the frequency of perineal incisions, and reduced perineal pain lasting up to 48 h postpartum in women giving birth for the first time. Similarly, Modoor et al. [
27] observed a significant reduction in pain during the second stage of labor and a lower incidence of second- and third-degree perineal ruptures.
A Cochrane review by Aasheim et al. [
28] confirmed that warm compresses reduce the risk of serious perineal injury. This is reflected in the guidelines issued by the Royal College of Midwives [
29], which support the use of warm compresses. Only the hands-off technique has been associated with a reduction in the rate of perineal incisions, though without a corresponding impact on the severity of injury [
28]. Therefore, the persistent belief among women—including those in the current study—that various techniques are effective for perineal protection remains puzzling. In a study by Trinh et al. [
30], published in 2015, 76.8% of obstetricians and 82% of midwives stated that the primary purpose of a perineal incision is to prevent uncontrolled rupture. Additionally, 56.5% of obstetricians and 36.7% of midwives reported a lack of training in methods to minimize perineal injury. Similarly, in a 2021 publication, Yang et al. [
31] found that 83.94% of obstetricians and 79.69% of midwives believed that performing a perineal incision had a protective effect against third- and fourth-degree perineal injuries. Furthermore, 80.29% of obstetricians and 82.57% of midwives identified a lack of training on perineal protection during childbirth as a major barrier to using alternative methods.
Carroll et al. [
32] reported that Irish midwives expressed a strong need for further training and courses on perineal protection techniques and the management of perineal injuries. Among the respondents in the current study, women with a higher level of knowledge most frequently cited medical staff, medical professionals active on social media, and materials found online as sources of knowledge. In a study by Haji et al. [
22], 49% of respondents reported the Internet and social media as their primary sources of information—these were the most frequently cited sources in that study group. In contrast, only 12.2% relied on information from medical professionals.
However, in a study conducted by Odo et al. [
24], as many as 60% of the women in the study group indicated doctors and midwives as the people from whom they drew their knowledge related to the issue of perineal incision, and this was the main source of knowledge, while materials found on the Internet accounted for only 3.3%. It can be concluded that accessibility to sources of knowledge can vary significantly depending on the population.
The presence of medical personnel on social media is playing an increasingly important role in women’s health education, particularly on perinatal topics. For example, in this group, 93.9% of respondents were aware of the existence of perineal protection methods, and 80.8% indicated that a woman’s consent is required to perform an episiotomy. It can be assumed that the accessible format of content, the regularity of posts, and real-time interactions (e.g., Q&A sessions, live broadcasts) build trust in educators and increase the effectiveness of knowledge transmission. Similar observations were made by Ventola [
33], who noted that social media can play a vital role in communicating medical information to patients and fostering engagement in the treatment process. Zhang et al. [
34] emphasized that an increasing number of patients use social media as a source of health information. In a pilot study, Baker et al. [
35] reported that 89% of pregnant women used social media to ask questions or seek advice related to pregnancy and/or parenting.
Marsh et al. [
36] pointed out, however, that the presence of midwives on the analyzed social media platforms was minimal, which limits the visibility of nonmedicalized approaches to pregnancy and childbirth. This may be particularly important for promoting evidence-based knowledge, as information shared by medical professionals is often perceived as more reliable than content from other sources [
34]. Medical staff on social media’ refers to healthcare professionals (e.g., midwives, obstetricians) sharing educational content via platforms like Instagram or Facebook. This is distinct from direct contact with providers in clinical settings.
In addition, Gholami-Kordkheili et al. [
37] examined the growing online presence of healthcare professionals and its implications for public health, emphasizing the importance of ethical standards, professionalism, and evidence-based content. This phenomenon reflects a broader shift toward digital medicine (e-health), where the educational role of medical personnel extends beyond clinics, hospitals, and birthing schools. The responsible digital engagement of doctors, midwives, and other healthcare professionals promotes greater health literacy and may contribute to more informed participation by women in the birthing process.
In our study, age, education, and childbirth history were significant predictors of knowledge, depending on the area analyzed. Women over 30 and those with childbirth experience demonstrated significantly higher knowledge levels regarding episiotomy. The age group under 25 had the least knowledge, highlighting the need to intensify educational efforts targeted at younger women, particularly those who have not yet given birth. Similar findings have been reported by other authors, who observed higher knowledge levels among women with previous childbirth experience [
22,
38,
39,
40].
Failure to inform the patient or performing the procedure without consent or against her will can be considered a form of institutional violence and may constitute obstetric violence. Obstetric violence refers to actions and omissions by medical personnel that violate a woman’s bodily and psychological integrity during pregnancy, during labor, and postpartum—often justified by “the welfare of the child” or “medical necessity” [
41]. In qualitative studies, women described being unable to refuse incisions, receiving no explanation for the intervention, and experiencing a lack of control over their bodies—factors contributing to traumatic childbirth memories [
41,
42]. Recognizing the right to informed consent and refusal is not only a legal aspect but also a key measure in preventing obstetric violence. It helps foster a sense of empowerment and safety for the parturient. In our study, a self-developed questionnaire written in colloquial language understandable by all patients was administered electronically and distributed through social networks and support groups. Online studies (e.g., Internet surveys) are often created by older, less educated, and rural people and may not be representative of these groups. There is also no way to verify a natural birth history.
Validated tools are commonly used in research; alternatively, “global assessment” measures based on direct self-reporting [
43,
44] or online surveys [
45] are also used. While validated instruments offer greater objectivity, they are often time-consuming. Non-validated instruments, such as “global assessments”, are easier to administer but may be more subjective [
46].
The results indicate a clear need to intensify educational efforts regarding the perineal incision procedure—its indications, alternatives, and potential consequences. Particular attention should be directed toward educating younger women who have not yet given birth, as this group reported the lowest level of knowledge. Social media can serve as an effective tool in this process, provided that content is created by qualified professionals and grounded in current guidelines and evidence-based medicine. It is also essential to emphasize every woman’s right to give or withhold consent for any medical intervention during childbirth. The findings of this study may serve as a foundation for future educational and organizational initiatives aimed at increasing women’s awareness and improving the standards of perinatal care in Poland.
