Question

Difficulty: MediumPreventive Care and Screening

Evaluate the following asymptomatic adult patients presenting to a general internal medicine clinic for their annual wellness visits. For each patient profile, identify the single most appropriate, guideline-concordant preventive care intervention to recommend today.

  • An asymptomatic 61-year-old man who accumulated 35 pack-years of tobacco use before ceasing the habit 8 years ago.Initiate annual low-dose computed tomography of the chest.
  • A healthy 41-year-old woman with no family history of malignancies presenting for a routine checkup.Schedule biennial screening mammography.
  • A 26-year-old woman whose last preventive gynecologic evaluation was at age 22, at which time all results were normal.Perform cervical cytology testing alone.
  • A 67-year-old woman with well-controlled hypertension who is entirely vaccine-naive since childhood.Recommend a single dose of the 20-valent pneumococcal conjugate immunization.
  • A 35-year-old man born in 1991 with no history of injection drug use or blood transfusions, establishing care.Order a one-time Hepatitis C virus antibody assay.

Answer

The 61-year-old former smoker should receive LDCT of the chest. The 41-year-old woman should receive biennial screening mammography. The 26-year-old woman is due for cervical cytology testing alone. The 67-year-old woman should receive a single dose of the 20-valent pneumococcal conjugate immunization. The 35-year-old man requires a one-time Hepatitis C virus antibody assay.
Each patient accurately aligns with a specific, current USPSTF or ACIP age- or risk-based guideline. The former smoker meets the 50-80 age, 20+ pack-year, and <15 years quit criteria for LDCT. The 41-year-old meets the updated >=40 years criteria for mammography. The 26-year-old is past the 3-year interval for cervical cytology. The 67-year-old is >65, requiring pneumococcal vaccination. The 35-year-old requires the universal 18-79 one-time HCV screen.

Step-by-Step Solution

1
Analyze the 61-year-old male's risk profile.
He is between ages 50 and 80, has a >20 pack-year smoking history (35), and quit <15 years ago (8).
This specific combination mandates annual lung cancer screening using LDCT based on USPSTF guidelines.
2
Evaluate the 41-year-old average-risk woman.
She is age 41. Recent USPSTF guideline updates lowered the starting age for breast cancer screening to 40.
Therefore, she is eligible for biennial screening mammography despite having no family history.
3
Assess the 26-year-old woman's cervical screening needs.
She is between 21 and 29 years old, meaning she requires cytology alone every 3 years. Her last test was 4 years ago.
She is overdue for cervical cytology, making it the appropriate next step.
4
Determine immunization needs for the 67-year-old woman.
She is older than 65 and vaccine-naive.
ACIP guidelines recommend pneumococcal vaccination for all adults 65 and older. PCV20 as a single dose is standard for naive patients in this age bracket.
5
Review the 35-year-old man's screening gaps.
He is an adult between 18 and 79 with no prior HCV screening.
USPSTF recommends universal, one-time HCV screening for all adults in this age range.
