Difficulty: HardPreventive Care and Screening

A 48-year-old woman comes to the clinic for a routine health maintenance examination. She has a history of systemic lupus erythematosus (SLE) that is well-controlled. Her daily medications include mycophenolate mofetil and 15 mg of prednisone, which she has been taking for the past three years. She is a former smoker with a 22-pack-year history, having quit 4 years ago. She has no new complaints today and feels well. Her last screening mammogram was performed 3 years ago and was normal. A screening colonoscopy was performed at age 45 and revealed no polyps or abnormalities. Cervical cytology with human papillomavirus (HPV) co-testing was performed 2 years ago and was normal. She received an inactivated influenza vaccine at a local pharmacy two weeks ago and has completed all routine childhood immunizations. She has never received a pneumococcal or herpes zoster vaccine.

Which of the following preventive interventions are indicated for this patient at today's visit? (Select all that apply)

  2. Administration of the 20-valent pneumococcal conjugate vaccineAnswer
  3. Screening mammographyAnswer
  4. D
    Low-dose chest computed tomography
  5. E
    Cervical cancer screening with human papillomavirus co-testing
  6. F
    Screening colonoscopy

Answer

The correct interventions are the administration of the recombinant zoster vaccine, administration of the 20-valent pneumococcal conjugate vaccine, and screening mammography.
The correct answers are the administration of the recombinant zoster vaccine, administration of the 20-valent pneumococcal conjugate vaccine, and screening mammography. This patient is considered severely immunocompromised due to her daily use of mycophenolate mofetil and moderate-dose prednisone for SLE. According to the Advisory Committee on Immunization Practices (ACIP), the recombinant zoster vaccine is recommended for adults aged 19 years and older who are immunocompromised. Similarly, the 20-valent pneumococcal conjugate vaccine (PCV20) is indicated for adults aged 19 to 64 years with immunocompromising conditions who have not previously received a pneumococcal vaccine. Finally, updated USPSTF guidelines recommend biennial screening mammography for women starting at age 40. Since her last mammogram was 3 years ago, she is overdue for breast cancer screening.

Step-by-Step Solution

1
Identify the patient's immune status based on her medication regimen.
The patient is severely immunocompromised due to chronic use of mycophenolate mofetil and moderate-dose prednisone (15 mg).
Immunocompromised status alters standard ACIP age cutoffs for several critical adult vaccines.
2
Evaluate the indication for specific vaccines.
The recombinant zoster vaccine and 20-valent pneumococcal conjugate vaccine (PCV20) are required.
ACIP recommends both RZV and PCV20 for immunocompromised adults aged 19 years and older, overriding the standard age-based triggers (50 and 65 years, respectively).
3
Assess the patient's breast cancer screening status against current USPSTF guidelines.
Screening mammography is indicated today.
USPSTF recommends biennial screening mammography starting at age 40. Because her last mammogram was 3 years ago (at age 45), she is overdue.
4
Evaluate indications for lung, cervical, and colorectal cancer screenings based on age and previous test intervals.
LDCT, cervical co-testing, and colonoscopy are not indicated today.
She does not meet the age cutoff for LDCT (50 years). Her previous cervical and colorectal screenings were normal and are within their respective 5-year and 10-year safe intervals.

Key Concept
