Difficulty: MediumPreventive Care and Screening

A 66-year-old biological female presents to the clinic for a routine health maintenance visit. Her past medical history is significant for well-controlled type 2 diabetes mellitus and primary hypertension. Her current medications include metformin and lisinopril. She has never smoked, drinks wine occasionally, and denies illicit drug use. She reports feeling well and has no current complaints.

A review of her medical records reveals the following:
- A screening colonoscopy performed at age 62 was unremarkable.
- A screening mammogram performed 6 months ago was normal.
- Dual-energy x-ray absorptiometry performed at age 65 showed osteopenia with a T-score of −1.4-1.4.
- She has a history of three consecutive normal Papanicolaou (Pap) tests, the most recent being at age 64.
- She received a tetanus, diphtheria, and acellular pertussis (Tdap) booster at age 60 and completed the recombinant zoster vaccine series at age 55.
- She has never received a pneumococcal vaccination.
- There is no record of prior hepatitis screening in her medical chart.

Based on current United States Preventive Services Task Force (USPSTF) and Advisory Committee on Immunization Practices (ACIP) guidelines, which of the following preventive interventions are indicated for this patient at today's visit? (Select all that apply)

  1. 20-valent pneumococcal conjugate vaccinationAnswer
  2. B
    Abdominal aortic aneurysm screening with ultrasonography
  3. C
    Cervical cancer screening with Papanicolaou testing
  4. Hepatitis C virus antibody testingAnswer
  5. E
    Low-dose computed tomography of the chest

Answer

The correct interventions are 20-valent pneumococcal conjugate vaccination and Hepatitis C virus antibody testing.
Based on current guidelines, two specific interventions are due for this 66-year-old patient. First, ACIP guidelines dictate that all adults aged 65 and older who have not previously received a pneumococcal conjugate vaccine should receive one (such as PCV20). Second, the USPSTF recommends a one-time screening for hepatitis C virus (HCV) infection for all adults aged 18 to 79 years; because she has no record of this, it is indicated today.

Step-by-Step Solution

1
Evaluate the patient's age and vaccination history for age-based immunization requirements.
The patient is 66 years old and has never received a pneumococcal vaccine. ACIP recommends PCV20 (or PCV15 followed by PPSV23) for all adults aged 65 and older.
Age is an independent indication for pneumococcal vaccination regardless of comorbidities.
2
Assess the need for routine age-based infectious disease screening.
The patient has no record of prior Hepatitis C testing. USPSTF recommends universal one-time HCV screening for adults aged 18 to 79.
HCV screening relies on a birth cohort/age-based approach rather than solely risk-factor targeting.
3
Review prior screening records to determine if any tests can be safely discontinued.
The patient had her last Pap test at age 64, with three consecutive normal results over the past decade. Because she is now older than 65 and meets the criteria for adequate prior screening, cervical cancer screening should be discontinued.
Continuing Pap testing in low-risk women over 65 provides minimal benefit and increases the risk of false positives and unnecessary procedures.
4
Analyze the patient's social history to determine indications for imaging-based screenings.
The patient has never smoked. Therefore, screening for an abdominal aortic aneurysm (AAA) and lung cancer (via LDCT) are contraindicated/not indicated.
AAA screening is recommended for men aged 65-75 who have ever smoked, and lung cancer screening requires a 20 pack-year smoking history.

Key Concept

Application of age- and risk-appropriate preventive screening and immunization guidelines (USPSTF and ACIP) in older adults.
