Zorluk: ZorPreventive Care and Screening

A 66-year-old woman visits her primary care physician for a comprehensive health evaluation. She feels well and reports no new symptoms. Her past medical history is notable for well-controlled hypothyroidism. Socially, she consumed one pack of cigarettes daily from age 18 to 48 but has strictly abstained from smoking for the past 18 years. Her mother was diagnosed with breast cancer at age 72. A review of her preventive health records reveals a completely normal screening colonoscopy at age 61, a normal bone dual-energy x-ray absorptiometry scan at age 65, and a normal screening mammogram at age 64. Her most recent cervical Papanicolaou smear with human papillomavirus co-testing was performed at age 64 and was negative; records confirm consistently negative cervical screening results over the preceding twenty years. She received a tetanus, diphtheria, and acellular pertussis (Tdap) booster three years ago and completed the recombinant zoster vaccine two-dose series at age 50. She has never received a pneumococcal vaccination. During the visit, she expresses anxiety regarding a friend's recent lung cancer diagnosis and asks, "Can we please do a CT scan of my lungs today to make sure they are clear?" Which of the following is the most appropriate preventive care plan for this patient?

  1. Advise against low-dose chest computed tomography, order a screening mammogram, and administer the 20-valent pneumococcal conjugate vaccineCevap
  2. B
    Order a low-dose chest computed tomography, order a screening mammogram, and administer the 20-valent pneumococcal conjugate vaccine
  3. C
    Advise against low-dose chest computed tomography, perform a cervical Papanicolaou smear with human papillomavirus co-testing, and defer pneumococcal vaccination
  4. D
    Order a low-dose chest computed tomography, schedule a screening colonoscopy, and administer the 23-valent pneumococcal polysaccharide vaccine
  5. E
    Advise against low-dose chest computed tomography, order a screening mammogram, and administer the recombinant zoster vaccine

Cevap

Advise against low-dose chest computed tomography, order a screening mammogram, and administer the 20-valent pneumococcal conjugate vaccine.
The correct preventive care plan addresses the patient's age and specific history by synthesizing multiple guidelines. First, her request for lung cancer screening with low-dose chest computed tomography (LDCT) must be denied; while she has a 30 pack-year history, she quit 18 years ago, exceeding the 15-year cessation limit established by the USPSTF. Second, she requires a screening mammogram because women aged 40 to 74 are recommended to undergo biennial screening, and her last mammogram was exactly two years ago at age 64. Finally, she requires a pneumococcal vaccination, as the ACIP recommends all adults aged 65 and older receive it (e.g., PCV20), and she has never received one.

Adım Adım Çözüm

1
Evaluate the patient's request for lung cancer screening.
Determine that low-dose computed tomography (LDCT) is not indicated.
Although the patient meets the age (50-80 years) and smoking history (≥20 pack-years) criteria, she quit smoking 18 years ago. The USPSTF explicitly recommends discontinuing LDCT screening once a person has not smoked for 15 years.
2
Assess the need for breast cancer screening.
Determine that a screening mammogram is due.
The USPSTF recommends biennial screening mammography for women aged 40 to 74. The patient is 66 and her last mammogram was 2 years ago (at age 64).
3
Review the patient's vaccination history against age-based guidelines.
Identify the need for pneumococcal vaccination.
The Advisory Committee on Immunization Practices (ACIP) recommends pneumococcal vaccination (e.g., a single dose of PCV20) for all adults aged 65 and older. The patient is 66 and vaccine-naive for pneumococcus.
4
Verify if any other routine screenings are due.
Determine that cervical and colorectal cancer screenings are up to date and/or no longer indicated.
Cervical cancer screening is discontinued at age 65 for women with adequate prior negative screening. Colorectal screening was normal at age 61 and is not due again until age 71 (10-year interval).
