Expert Commentary

Thanks for this clear and succinct post. The differential diagnosis of lower abdominal and pelvic pain is extremely broad in both premenopausal and post-menopausal women. This is when the sexual history becomes important. A question we often overlook as part of the sexual history is asking about dyspareunia, which may help differentiate gynecological from intra-abdominal causes of abdominal pain, specifically in the case of PID. 

Patients with PID are frequently misdiagnosed with a urinary tract infection because they may have urinary symptoms, but the urinalysis often shows sterile pyuria, which should raise your suspicion for PID. 

And while the utility of the pelvic exam is constantly scrutinized and questioned in patients with vaginal bleeding, it is impossible to diagnose PID without it. Having said that, the clinical diagnosis is only 65-90% specific so even minimal symptoms with no other explanation warrant antibiotic therapy to reduce further complications. 

Underdiagnosis is even more significant in the adolescent patient population, who are at highest risk for developing PID. Over 70% of PID diagnoses among adolescents are made in the ED, with approximately 200,000 adolescents diagnosed annually. If the patient is accompanied by a family member or friend, having them step out to better elicit a sexual history is essential. HIV and syphilis testing should also be considered while these patients are in the ED. 

Ensuring follow-up for these patients within 48-72 hours is essential and must be emphasized. Patients should understand the complications of PID and the importance of antibiotic compliance prior to discharge, especially in younger patients.

Vaginal Self Swabbing

The Antiquated Pelvic Exam?

As Emergency Medicine physicians the demand to see more patients and expedite turnaround times all while providing quality care and maintaining patient satisfaction is steep. Our attempt to meet these standards is truly tried when posed with having to perform a pelvic exam during a busy shift. Introducing patient self-swabbing: an opportunity to provide quality care while saving precious time and resources.

Chlamydia is the most common infection reported in the United States, particularly among high risk populations such as females ages 15 to 24 [1]. These patients are most likely to present to the Emergency Department for their symptoms, thus it remains the task of the Emergency Medicine physician to screen and diagnose sexually transmitted infections to aid in avoiding complications of infection such as pelvic inflammatory disease, infertility, and ectopic pregnancy [1].

The gold standard for making the diagnosis has traditionally been through the physician-obtained endocervical swab on pelvic exam, an exam than has been shown to be physically and emotionally uncomfortable for a majority of patients, as well as low yield [2]. In 2012 a study at an urban sexual health center on women 16 years of age or older presenting with and without vaginal discharge or bleeding compared self-swabs to physician collected endocervical samples. Self-swabs were more sensitive in detecting chlamydia by nucleic acid amplification tests (NAAT) when compared to physician swabs; compared to self-swabs 1 out of 11 cases were missed by physician collected swabs, an overall 9% miss rate [3]. Patient self-swabs are equivalent to physician swabs in detecting gonorrhea [4] The difference in sensitivity has been attributed to patients having more contact time with the vaginal wall and removing more mucus when self-swabbing compared to when physicians collect samples [5].

Another study performed at two urban teaching hospitals in New York looked at self-swabs versus physician collected swabs in order to assess if self-swabs were as sensitive at diagnosing chlamydia infection within the Emergency Department. Overall self-swabs were 91% sensitive and 99% specific at identifying infection, thus deemed a reasonable alternative to physician collected samples, and implemented as an alternative in order to save time and resources.(6) Currently, self-swabbing is supported by ACOG, AAFP, and the CDC [2, 7, 8].

So why aren’t we doing this more? Inherently, as Emergency Medicine physicians, we are always seeking out the big, the bad, and the ugly, be it a fungating mass, or a case of pelvic inflammatory disease. While the idea of the self-swab shouldn’t obviate the pelvic exam, it can be useful in populations with a history and symptoms suggestive of a sexually transmitted infection, as well as for patients seeking screening after known exposure, or even for patients who refuse to undergo a pelvic exam [2, 7] In addition, patients prefer to obtain self-swabs.(8) While one can argue time is still lost in having to instruct the patient on how to self-swab, its practice in the outpatient clinical setting has become so common that there are numerous resources to aid in patient education, including easy-to-understand diagrams, like the one below, made to adorn bathroom walls [9].

Self swabs have been shown to be less messy, cost-effective, as well as thought to be easy to perform by the majority of patients [10]. When striving to increase efficiency, all the while improving patient care, every second counts. Self-swabbing is one method that can buy back time well-spent.


Expert Commentary

While this terrific post specifically focuses on the use of self-administered vaginal swabs for the evaluation of cervicitis in the emergency department, the broader utility of the pelvic exam for ED patients has been repeatedly called into question [1, 2]. As you correctly point out, pelvic exams are  uncomfortable, can be distressing for patients, and frequently introduce delays in the patient’s care.

In addition to the evidence supporting self-swabs cited in this post, a 2018 ED-based study suggests the pelvic exam does not increase the sensitivity or specificity of diagnosing chlamydia, gonorrhea, or trichomonas when compared to taking a history alone [3]. While any individual study of this type will be limited by methodologic issues, there does appear to be broad support in the literature for routine use of self-administered swabs.

So why aren’t we doing this? Clinical practice can be slow to change, and that seems to be the case for this topic. I also think this highlights a fundamental feature of the emergency medicine mindset: the emphasis on identifying “bad” conditions, despite an anticipated low likelihood. While I have never personally visualized an unexpected cervical malignancy or traumatic injury during a pelvic exam in the ED, many emergency clinicians fear “missing something” in the absence of direct visualization. But as the 2018 paper highlights, taking an appropriate history should mitigate these concerns. Finally, as this post mentions, patients must be instructed on how to properly perform a self-administered swab, and any education should be appropriate to the patient’s primary language and degree of health literacy.

Ovarian Hyperstimulation: Not Your Ovarian Average Cyst

Pregnancies resulting from assisted reproduction are more complicated, with higher rates of ectopic, heterotopic and multifetal pregnancies, in addition to higher rates of abortions and premature deliveries. Other complications include venous thromboembolism as well as ovarian hyperstimulation syndrome. These are high risk pregnancies that will present to your emergency department and you should be aware of key management principles.
