Zorluk: ZorPreventive Care and Screening

A 54-year-old man presents to the clinic to establish care. He has not seen a physician in five years. His medical history includes type 2 diabetes mellitus, hypertension, and stage 3a chronic kidney disease. Current medications include lisinopril, amlodipine, metformin, and empagliflozin. He smoked 1.5 packs of cigarettes daily from age 18 until he quit at age 48. His family history is notable for a father who was diagnosed with colorectal cancer at age 65. The patient's last colonoscopy was at age 49 and showed no polyps. He received an annual influenza vaccine at a local pharmacy three weeks ago. His tetanus-diphtheria-acellular pertussis (Tdap) vaccination is up to date, and he completed the hepatitis B vaccine series in his 30s. He has never received a pneumococcal vaccine or a zoster vaccine. Which of the following combinations of preventive interventions is most appropriate for this patient today?

  1. Administer the 20-valent pneumococcal conjugate vaccine (PCV20) and order a low-dose chest CTCevap
  2. B
    Administer the 20-valent pneumococcal conjugate vaccine (PCV20) and order a screening colonoscopy
  3. C
    Administer the 23-valent pneumococcal polysaccharide vaccine (PPSV23) and order a low-dose chest CT
  4. D
    Administer the recombinant zoster vaccine (RZV) and order a screening abdominal ultrasound
  5. E
    Administer the 23-valent pneumococcal polysaccharide vaccine (PPSV23) and order a screening colonoscopy

Cevap

Administer the 20-valent pneumococcal conjugate vaccine (PCV20) and order a low-dose chest CT
The correct answer accurately identifies that the patient requires lung cancer screening and an updated pneumococcal vaccination. The USPSTF recommends annual low-dose chest CT (LDCT) for adults aged 50-80 years who have at least a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. This 54-year-old patient has a 45 pack-year history and quit 6 years ago, making LDCT strongly indicated. Furthermore, ACIP guidelines recommend that adults aged 19-64 years with certain underlying medical conditions (including diabetes and chronic kidney disease) who have not previously received a pneumococcal conjugate vaccine should receive a single dose of PCV20 (or a dose of PCV15 followed by PPSV23). Therefore, administering PCV20 and ordering a LDCT are both indicated today.

Adım Adım Çözüm

1
Calculate smoking pack-years and verify lung cancer screening eligibility.
The patient smoked 1.5 packs/day for 30 years (45 pack-years) and quit 6 years ago. At age 54, he meets criteria for annual low-dose chest CT (LDCT).
USPSTF recommends LDCT for adults 50-80 with a ≥20 pack-year history who currently smoke or quit within the past 15 years.
2
Determine appropriate pneumococcal vaccination based on medical history.
The patient is under 65 but has diabetes and chronic kidney disease, making him eligible for pneumococcal vaccination. As a vaccine-naive adult, he should receive PCV20.
Current ACIP guidelines recommend a single dose of PCV20 (or PCV15 followed by PPSV23) for adults 19-64 with risk factors.
3
Evaluate the need for colorectal cancer screening based on family history.
His father was diagnosed at age 65 (≥60 years old). His screening began before 50, but the surveillance interval remains 10 years following a normal exam. His last was at age 49, so the next is due at 59.
Ensures adherence to interval guidelines and prevents unnecessary invasive testing.
4
Check eligibility for abdominal aortic aneurysm (AAA) screening.
The patient is 54 years old, which is too young for AAA screening.
USPSTF recommends one-time AAA screening with ultrasound only for men aged 65-75 who have ever smoked.
