Pelvic Inflammatory Disease
Key Points
- PID is an ascending infection from the lower to the upper reproductive tract, most often caused by Neisseria gonorrhoeae or Chlamydia trachomatis.
- Nearly one million women are affected annually; permanent tubal scarring leads to infertility and increased ectopic pregnancy risk.
- Diagnosis is primarily clinical based on symptoms; sonography or biopsy may confirm when necessary.
- Treatment requires combination antibiotics (ceftriaxone, doxycycline, metronidazole) and partner treatment for STIs.
Pathophysiology
PID results from the ascent of bacteria from the cervix and vagina into the upper reproductive tract, including the uterus, fallopian tubes, and ovaries. The infection is most commonly caused by sexually transmitted bacteria, particularly Neisseria gonorrhoeae and Chlamydia trachomatis, though other bacterial, viral, fungal, or parasitic organisms may be responsible. The inflammatory response causes edema, tissue damage, and adhesion formation within the reproductive structures. Repeated or untreated infection leads to permanent scarring that narrows or occludes the fallopian tubes, significantly increasing the risk of ectopic-pregnancy and infertility.
Clinical Manifestations
- Lower abdominal and pelvic pain (most common presenting symptom).
- Abnormal vaginal discharge (purulent or mucopurulent).
- Fever and systemic signs of infection.
- Irregular menstrual bleeding.
- Painful sexual intercourse (dyspareunia).
- Reported history of sexually transmitted infection.
Nursing Assessment
NCLEX Focus
PID assessment questions often focus on identifying risk factors (multiple sexual partners, unprotected intercourse, history of STIs) and distinguishing PID from other causes of lower abdominal pain such as appendicitis or ectopic pregnancy.
- Obtain a thorough sexual and gynecological history in a nonjudgmental manner.
- Assess for cervical motion tenderness and adnexal tenderness during pelvic examination.
- Monitor vital signs for fever and hemodynamic changes.
- Review laboratory results: CBC, ESR, CRP, cervical cultures for gonorrhea and chlamydia.
- Assess for signs of tubo-ovarian abscess (persistent fever, palpable adnexal mass).
Nursing Interventions
- Administer prescribed antibiotics: typically ceftriaxone (IM), doxycycline (oral, 14 days), and Metronidazole (oral) in combination.
- Educate the patient that all sexual partners must be tested and treated to prevent reinfection.
- Encourage completion of the full antibiotic course even if symptoms improve.
- Teach safe sexual practices including consistent condom use to reduce future risk.
- Provide psychosocial support regarding potential effects on fertility; initiate referrals for counseling as needed.
- Educate the patient to report worsening symptoms (high fever, severe abdominal pain) that may indicate abscess or peritonitis.
Ectopic Pregnancy Risk
Patients with a history of PID have a significantly increased risk of ectopic pregnancy. Educate about early pregnancy symptoms and the importance of early prenatal care.
