Difficulty: HardPreventive Care and Screening

A 5252-year-old man presents to the clinic for a general health assessment. He was recently hired for a new job and wishes to ensure his immunizations and screenings are up to date, noting he has not seen a healthcare provider since he was 4646 years old. He has no physical complaints and takes no prescription medications. He has smoked 11 pack of cigarettes daily since age 2222. His body mass index is 32 kg/m232 \text{ kg/m}^2, and his blood pressure is 126/78 mmHg126/78 \text{ mmHg}. A review of his past medical records reveals a negative fourth-generation HIV test, a negative hepatitis C antibody test, and a normal screening colonoscopy, all performed 66 years ago. Based on current guidelines, which of the following preventive interventions are indicated for this patient during today's visit? (Select all that apply)

  2. Recombinant zoster vaccinationAnswer
  3. Hemoglobin A1c measurementAnswer
  4. D
    Prostate-specific antigen testing
  5. E
    Screening ultrasonography of the abdominal aorta
  6. F
    Repeat screening colonoscopy

Answer

The correct interventions are low-dose computed tomography of the chest, recombinant zoster vaccination, and hemoglobin A1c measurement.
Based on current USPSTF and ACIP guidelines, a 52-year-old male with a 30 pack-year smoking history and obesity qualifies for three distinct interventions simultaneously. First, annual low-dose computed tomography is indicated for lung cancer screening (ages 50-80, >=20 pack-years, current smoker). Second, the recombinant zoster vaccine series is recommended for all adults starting at age 50. Third, screening for type 2 diabetes mellitus with a Hemoglobin A1c or fasting glucose is indicated for adults aged 35 to 70 who are overweight or obese.

Step-by-Step Solution

1
Calculate the patient's pack-year smoking history.
He has smoked 1 pack per day for 30 years (from age 22 to 52), yielding a 30 pack-year history.
Accurate pack-year calculation is required to determine eligibility for lung cancer screening.
2
Assess eligibility for lung cancer screening.
Screening is indicated because he is between 50 and 80 years old, has a >20 pack-year history, and is a current smoker.
Annual low-dose computed tomography is standard of care for patients meeting these specific risk criteria.
3
Evaluate age-based adult immunization requirements.
The recombinant zoster vaccine is indicated.
All adults aged 50 and older require the 2-dose recombinant zoster vaccine series, regardless of prior chickenpox or shingles history.
4
Assess metabolic screening criteria based on physical parameters.
Diabetes screening (e.g., Hemoglobin A1c) is indicated.
The patient is in the 35 to 70 age range and has a body mass index indicating obesity, satisfying USPSTF criteria for diabetes screening.
5
Rule out premature or incorrectly sequenced screening modalities.
Prostate-specific antigen testing, abdominal aortic aneurysm screening, and colonoscopy are rejected.
The patient is too young for routine prostate cancer screening (starts at 55) and abdominal aortic aneurysm screening (starts at 65). His colonoscopy interval is 10 years, so he is not due for another 4 years.

Key Concept

Age- and risk-appropriate preventive screening and immunizations for middle-aged adults based on USPSTF and ACIP guidelines.
