Zorluk: Çok zorPreventive Care and Screening

A 54-year-old biological female presents to the clinic for a routine health maintenance visit. Her medical history is significant for hypertension, hyperlipidemia, and chronic kidney disease stage 3a with a baseline estimated glomerular filtration rate of 52 mL/min/1.73 m². She is a former smoker who smoked 1.5 packs of cigarettes per day from age 37 to age 49 (a total of 12 years) before quitting completely 5 years ago. Current medications include lisinopril and rosuvastatin. Her body mass index is 29 kg/m².

Vaccination history:
- Up to date on seasonal influenza and COVID-19 vaccines.
- Received a Tdap booster 4 years ago after a minor kitchen laceration.
- Received two doses of the recombinant zoster vaccine at age 51.
- She has never received a pneumococcal vaccine.

Screening history:
- Screening colonoscopy at age 48 was completely normal.
- Pap smear with HPV co-testing 3 years ago was negative for intraepithelial lesion or malignancy.
- Hepatitis C virus antibody testing at age 50 was negative.
- Screening mammography 11 months ago was interpreted as BI-RADS 1 (negative).

Which of the following is the most appropriate next step in preventive care and screening for this patient today?

  1. Administration of 20-valent pneumococcal conjugate vaccineCevap
  2. B
    Low-dose computed tomography of the chest
  3. C
    Screening mammography
  4. D
    Dual-energy x-ray absorptiometry scan
  5. E
    Pap smear with human papillomavirus co-testing

Cevap

Administration of 20-valent pneumococcal conjugate vaccine
The correct answer is the administration of the 20-valent pneumococcal conjugate vaccine (PCV20). According to current ACIP guidelines, adults aged 19-64 with certain underlying medical conditions—including chronic kidney disease (CKD), chronic heart or lung disease, diabetes, and current smoking—are at increased risk for pneumococcal disease and should receive pneumococcal vaccination. Because this patient has CKD stage 3a and has never received a pneumococcal vaccine, a single dose of PCV20 is indicated today.

Adım Adım Çözüm

1
Calculate the patient's smoking pack-years to evaluate lung cancer screening eligibility.
1.5 packs per day multiplied by 12 years equals 18 pack-years.
USPSTF guidelines require a minimum of 20 pack-years for low-dose CT screening. She fails to meet this quantitative threshold.
2
Review the patient's current age and chronic medical conditions against ACIP immunization schedules.
The patient is 54 years old and has chronic kidney disease (CKD) stage 3a.
While routine pneumococcal vaccination begins at age 65, adults aged 19-64 with specific high-risk conditions (including CKD) are indicated to receive it early.
3
Verify the intervals of her recent cancer screenings.
Mammogram was 11 months ago (due every 2 years), Pap/HPV was 3 years ago (due every 5 years), and colonoscopy was 6 years ago (due every 10 years).
Ensures no routine cancer screenings are prematurely ordered before their guideline-directed intervals.
