Background
A bimanual pelvic examination (BPE) is used to check a woman’s internal pelvic organs. The health care provider inserts two fingers into the vagina and then places pressure with the other hand to the lower part of the belly.
The American College of Obstetricians and Gynecologists recommends BPEs only if young women have a medical history or certain symptoms like pelvic pain and unusual bleeding. The American College of Physicians and the American Academy of Family Physicians do not recommend performing BPEs on women who are not pregnant and are not having health problems.
BPEs are not recommended before prescribing most hormonal contraceptives (including birth control pills), or during screening for sexually transmitted infections.
A Pap test is used to check for cervical cancer by placing a speculum (medical tool) inside the vagina to collect cells from the cervix.
Cervical cancer screening is not recommended for women younger than 21 years, according to leading professional organizations.
The harms of unnecessary tests
Unnecessary BPE and Pap tests could cause several harms, such as:
- Fear.
- Anxiety.
- A false positive test result (a test result that tells you a disease or condition is present, when in reality, there is no disease).
- Unnecessary treatments.
- Unnecessary costs.
Given these possible harms, it’s important for young women to receive BPEs and Pap tests only when necessary. BPEs and Pap tests should be a shared decision between the patient and the health care provider.
About the study
CDC researchers used data from the National Survey of Family Growth to estimate the number of potentially unnecessary tests in young women aged 15 to 20 in the United States. The data were combined from the years 2011 to 2017.
Survey participants were asked if they had received a Pap test or a BPE in the past 12 months.
The BPEs were classified as either medically needed (the test was necessary) or potentially unnecessary.
The exam was considered medically needed if the young woman:
- Was pregnant.
- Used an intrauterine contraceptive device (IUD).
- Received the test because of a medical problem.
- Received treatment for a sexually transmitted infection such as chlamydia, gonorrhea, syphilis, or genital herpes.
Key findings
The study estimated that 1.4 million BPEs and 1.6 million Pap tests performed on females in the United States aged 15 to 20 in a single year may have been medically unnecessary.
The study also found:
- Young women who had a Pap test were 7 times more likely to report also receiving a BPE, compared with young women who did not have a Pap test.
- Young women who had been screened for a sexually transmitted infection were 4 times more likely to receive a Pap test and 60% more likely to receive a BPE, compared with young women who had not been screened.
- Young women who used a hormonal contraception method other than an IUD were 75% more likely to receive a Pap test and 31% more likely to receive a BPE, compared with young women who did not use non-IUD hormonal contraception methods.
How to avoid unnecessary BPEs and Pap tests
The study concluded that efforts to avoid unnecessary BPEs and Pap tests among young women could include:
- Educating health care providers and women about when exams and tests are necessary.
- Encouraging parents and patients to ask health care providers about when exams are appropriate.
- Making a shared decision between the patient and the health care provider about whether exams and tests are necessary.
