Zorluk: OrtaPreventive Care and Screening

A 52-year-old woman establishes care at a primary care clinic for a comprehensive wellness evaluation. She has a past medical history of essential hypertension that is well controlled on amlodipine. She currently smokes half a pack of cigarettes daily and has a 15-pack-year smoking history. She has no history of intravenous drug use, blood transfusions, or high-risk sexual behavior. A review of her lifelong medical records reveals that she has never undergone screening for hepatitis C. Her last screening colonoscopy at age 45 was normal. A screening mammogram performed 6 months ago was normal. Cervical cytology with high-risk human papillomavirus (hrHPV) co-testing was performed 3 years ago and was negative. She received a tetanus, diphtheria, and acellular pertussis (Tdap) booster 4 years ago and had an influenza vaccine last month. Physical examination is unremarkable. Her body mass index is 26 kg/m². Based on current guidelines, which of the following preventive interventions are indicated for this patient during today's visit? (Select all that apply)

  1. Recombinant zoster vaccinationCevap
  2. Hepatitis C virus antibody testingCevap
  3. C
    Low-dose computed tomography of the chest

    Dual-energy x-ray absorptiometry scan
  5. E
    Cervical cytology with human papillomavirus co-testing

Cevap

The indicated interventions are the recombinant zoster vaccination and Hepatitis C virus antibody testing.
Based on current guidelines, the recombinant zoster vaccination and Hepatitis C virus antibody testing are both indicated for this patient today. The Advisory Committee on Immunization Practices (ACIP) recommends the two-dose recombinant zoster vaccine for all immunocompetent adults starting at age 50, regardless of prior herpes zoster episodes. Additionally, the United States Preventive Services Task Force (USPSTF) recommends a one-time screening for hepatitis C virus (HCV) infection in all asymptomatic adults aged 18 to 79 years, superseding the older birth-cohort (baby boomer) recommendation. Since this 52-year-old patient has never been screened, HCV antibody testing is appropriate.

Adım Adım Çözüm

1
Evaluate the patient's age and vaccination history for adult immunizations.
The patient is 52 years old, making her eligible for the recombinant zoster vaccine, which starts at age 50.
Vaccination schedules dictate age-based milestones independent of chronic disease status.
2
Assess the need for infectious disease screening based on age and history.
The patient has no specific risk factors for Hepatitis C but is between 18 and 79 years old and has never been screened.
Current guidelines recommend one-time universal screening for HCV for all adults in this age group.
3
Calculate the smoking pack-year history to determine lung cancer screening eligibility.
The patient has a 15-pack-year history, which falls below the 20-pack-year threshold.
Guidelines explicitly require at least 20 pack-years for annual low-dose CT screening.
4
Review the intervals for previously completed age-appropriate screenings (cervical, breast, colorectal).
Cervical co-testing was done 3 years ago (due every 5), colonoscopy at 45 (due at 55), and mammogram 6 months ago (due every 1-2 years).
Routine screening intervals should not be shortened without specific clinical indications.
