Antenatal History: How to Conduct a Comprehensive Assessment

Antenatal history is a crucial step in maternal-fetal healthcare. Effective prenatal care begins with a comprehensive assessment of the pregnant woman's medical, obstetric, and social history, providing essential information for appropriate and individualized pregnancy management.

The data collection covers maternal age, preexisting diseases, previous pregnancies, family history, lifestyle habits, and socioeconomic conditions. Maternal age can influence the risk of complications, with specific challenges for both very young and older pregnant women. Preexisting diseases, such as hypertension, diabetes, and autoimmune diseases, require careful monitoring and therapeutic planning. Obstetric history, including abortions, premature births, or cesarean sections, is crucial for managing the current pregnancy. Evaluating social factors, such as family support and working conditions, is essential to identify psychosocial risks and provide comprehensive prenatal care.

By conducting a detailed antenatal history, healthcare professionals can identify potential risks, plan preventive interventions, and provide patient-centered care. Understanding the pregnant woman's concerns and expectations, as well as advising on healthy habits, can make a significant difference in pregnancy outcomes, contributing to the promotion of maternal-fetal health.

In this article, we will explore in detail the essential elements of antenatal history and how to conduct a comprehensive assessment that contributes to a healthy and successful pregnancy.

Importance of Antenatal History

A comprehensive antenatal history allows for early identification of potential risk factors for complications during pregnancy and childbirth. It provides the health professional with a holistic view of the patient's health status and history, allowing for the development of a personalized care plan. The main reasons for conducting a comprehensive antenatal history include:

1. Identification of Risk Factors: Allows early identification of medical conditions or previous complications that may impact the current pregnancy, such as hypertension, diabetes, or preterm labor.
2. Individualized Care Planning: Facilitates the development of an obstetric care plan tailored to the specific needs of the pregnant woman.
3. Promotion of Maternal and Fetal Health: Antenatal care includes preventive interventions such as vaccination, supplementation, and nutritional guidance.
4. Patient Education: Provides an opportunity to clarify doubts and guide the necessary care during pregnancy.

Components of Antenatal History

The antenatal history should cover several areas of the pregnant woman's health and history. Let's explore in detail each essential component:

1. Obstetric History

Obstetric history is crucial for predicting complications and guiding the management of antenatal care.

• Previous Pregnancies: Number of previous pregnancies (pregnancy, miscarriage, stillbirth, preterm birth, full-term birth).
• Pregnancy Outcomes: Including details such as complications, type of delivery, birth weight, gestational age, and baby's gender.
• Previous Complications: Preeclampsia, gestational diabetes, preterm labor, premature rupture of membranes, among others.
• History of Cesarean Section: Reason and type of incision.
• Postpartum Complications: Infections, hemorrhage, postpartum depression.

2. Gynecological History

Gynecological history helps identify possible pre-existing conditions.

• Menstrual Cycles: Regularity, duration, flow characteristics, dysmenorrhea.

• Genetic Diseases: Analyze the presence of hereditary diseases in the family, such as cystic fibrosis, sickle cell anemia, thalassemia.
• Chronic Conditions: Diabetes, hypertension, cardiovascular disease, cancer.
• Family Obstetric History: Recurrent miscarriages, preterm labor, preeclampsia.

6. Psychosocial History

The mental and emotional health of the pregnant woman is essential for quality antenatal care.

• Psychiatric Conditions: Anxiety, depression, eating disorders, mood disorders.
• History of Sexual Abuse: Approach the topic sensitively and respectfully.
• Stress: Significant stressors in the pregnant woman's life.

7. Current Pregnancy

Assessing the current pregnancy allows for initial planning of consultations and tests.

• Gestational Age: Last menstrual period (LMP), initial ultrasound.
• Symptoms: Nausea, vomiting, bleeding, abdominal pain, signs of urinary tract infection.
• Medications: Current use of medications, supplements, and herbal medicines.
• Initial Antenatal Tests: Beta-hCG, complete blood count, blood glucose, serology, ultrasound.

Additional Considerations

In addition to the main components of antenatal history, some additional considerations can be made to ensure an even more comprehensive assessment.

Patient Relationship

Establishing a relationship of trust and respect is essential to obtain accurate and complete information.

• Welcoming Environment: Provide privacy and comfort during the consultation.
• Active Listening: Show empathy and genuine interest in the patient's story.
• Clear Guidelines: Explain the reason for the questions and the importance of responding honestly.

Data Recording

Accurate and detailed documentation of the antenatal history is crucial for monitoring the pregnant woman.

• Complete Record: Include all components of the history clearly.
• Confidentiality: Ensure that the patient's data is kept confidential.
• Regular Update: Review and update the history during subsequent consultations.

Use of Standardized Questionnaires

Standardized questionnaires can be useful for a quick and comprehensive assessment.

• Obstetric Risk Questionnaire: Identification of risk factors for complications.
• Depressive Symptom Inventory: Assessment of perinatal depression risk.
• Domestic Abuse Screening: Discreet and sensitive questionnaires.

Prenatal History and Ninsaúde Clinic: Simplifying Comprehensive Assessment and Care

You already know that prenatal history is a fundamental element in maternal-fetal health monitoring. But did you know that with Ninsaúde Clinic medical software, healthcare professionals can record the entire prenatal history practically and comprehensively through the electronic medical record? The system also enables telemedicine appointments, where the doctor can conduct video consultations while entering observations and data directly into the record.

Furthermore, Ninsaúde Clinic offers a form insertion feature that allows detailed histories to be included and automatic prenatal calculations to be performed. Let's explore some of the main features that facilitate comprehensive assessment during prenatal history:

Calculation of EDD by LMP

With the Last Menstrual Period (LMP), Ninsaúde Clinic automatically calculates the Estimated Due Date (EDD). Simply create a "Date" question to enter the LMP and another "Calculated Date" question with the appropriate formula to obtain the EDD automatically.

Calculation of EDD by Ultrasound (US)

To calculate the EDD from the ultrasound (US), enter the date of the ultrasound in a "Date" question and the Gestational Age (GA) in a "Number" question. A "Calculated Date" question will then automatically present the EDD.

Date of Conception

To calculate the date of conception, create a "Calculated Date" question with the correct formula and include the "LMP" question (as a "Date" field) in the same form for accuracy.

Calculation of Gestational Age (GA)

With the LMP, the calculation of gestational age can be done using a "Calculated Field." The formula considers the current date and the date of conception to provide the exact gestational age in weeks.

Impact of Detailed History on Prenatal Care

Antenatal history is a powerful tool to ensure quality obstetric care. A comprehensive assessment allows for the identification of risk factors, the planning of preventive interventions, and the education of the pregnant woman about pregnancy care. Therefore, when conducting the history, the healthcare professional should cover all the essential components, promoting successful prenatal care and contributing to maternal-fetal health.

In addition, antenatal history provides a valuable opportunity to establish a trusting relationship between the pregnant woman and the healthcare professional. This relationship is crucial for the woman to feel comfortable sharing concerns and challenges, enabling the professional to offer more individualized support. Understanding psychosocial factors such as anxiety, depression, or stress can help direct additional interventions, such as referrals for psychological support or support groups, promoting not only physical health but also the emotional well-being of the pregnant woman.
